From RationalWiki
Jump to: navigation, search
Hop on, it'll be loads of fun
A "bandwagon" argument says that because "everyone is doing it (or thinking it or saying it), you also should".[1]
Contents
[edit] Form
The logical argument here is:
• Everyone (the majority) is doing it.
• The majority is always right.
• If I do it, I will be in the majority, and therefore right.
The argument is problematic because unfortunately, the premise "the majority is always right" may not be true. When phrased like this, few people would say that they'd fall for such a stupid thing - but it's still a remarkably easy trap to fall into, precisely because people don't realise that it's a bandwagon that they're jumping on. In a manner similar to the Matthew effect[wp], something that gains attention (legitimately or otherwise) will attract more interest. This interest generates more interest, like an internet meme circulating around internet forums, and before you know it everyone is on the bandwagon shouting "yee haw!!" While this is merely just how information tends to propagate, the bandwagon argument truly becomes fallacious when people use it as an excuse to say that an issue is important or that the circulating opinion must be correct.
[edit] Examples
Jumping on the bandwagon is the seizing of current events or taking on board of recent popular opinion, by politicians or political parties in order to attract popular support.
In the UK the tabloid press (red tops) are sometimes accused of 'rabble rousing' (e.g. paedophilia hysteria), leading to much public debate and political posturing. Politicians are forced to take a position on such events and the opposition, of whatever party, 'jumps on the bandwagon' by condemning the Government's record and their legislative plans. An recent example was widespread flooding in South-West England caused by heavy rain and the political reaction to it; the opposition parties made great capital of the state of flood defences, the preparedness and financing of the emergency services and building of homes and businesses on flood plains.
It should be noted that it is not necessary for the facts to get in the way of a good argument, the bandwagon has its own momentum and will carry its passengers whether true or not.
Sometimes, when events are due to external causes, both political sides will jump onto the same bandwagon and each will accuse the other of doing so (e.g. Terrorism).

Nairobi
From Wikitravel
Jump to: navigation, search
Nairobi is the capital of Kenya and the largest city in the country.
Contents
[edit] Understand
Nairobi has a population of three million plus. Situated on the Nairobi River, the city is not only the largest and fastest growing city in Kenya, but one of the largest in Africa.
[edit] History
The word Nairobi derives from a water hole known in Maasai (an Eastern Nilotic language) as Enkare Nyirobi, which means "cool waters." Nairobi, which was a swamp area, was founded in 1899 and was first a railway camp for the Uganda Railway. The city became Kenya’s capital, which was Mombasa initially, and it also became the capital of the British East Africa Protectorate in 1905. With the spread of plagues in the early 1900s, the town was burnt down and had to be rebuilt. Having a railroad system in the system helped it to have drastic growth, becoming the second largest city in Kenya behind Mombasa.
The city of Nairobi also grew due to administration and tourism businesses (mostly big game hunting). The British, who were one of Kenya’s colonizers, set up shop in Nairobi, leading to the creation of big hotels primarily for the British hunters. Also, Nairobi has an East Indian community from those who are the descendents of original colonial railway laborers and merchants.
[edit] Get in
Citizens from most countries will have to obtain a visa upon arrival. Currently, this costs US$50 for a single-entry visa and $100 for a multiple-entry visa (Euros, British Pounds and Swiss Francs are accepted as well). However, some countries require a visa before arrival, and some don't require one at all.
For more information, see the Kenya article. If you are only traveling through the country via a connecting flight and will not leave the secure area of the airport you will not need a visa.
The yellow fever vaccination is no longer required if you're coming from EU, Asia or North America. However, a vaccination certificate might be required if you're coming from a country where yellow flu is endemic.
[edit] By plane
Regular flights to Nairobi are operated by Air France,Air Kenya, British Airways, Egypt Air, Etihad Airways, Fly Emirates, Kenya Airways, KLM, Lufthansa, Qatar Airways, Swiss International Airlines, Turkish Airlines, and Virgin Atlantic. Kenya Airways is the national airline and travels throughout Europe, Africa, and the Asia-Pacific region. Nairobi’s main airport is JKIA Jomo Kenyatta International Airport (IATA: NBO), 15 kilometers (9 mi) southeast from the center of the city.
If taking a taxi from JKIA, use a reputable taxi; many are waiting outside to give you conveyance, and the cost should be very near 1,500KSh to the city center; Westlands or such places more west or north will be more. When taking a taxi to your accommodation, avoid being talked into taking their recommendation for accommodation, although this is very at your own risk. There is also Wilson Airport, 11 km (7 mi) south from the city's center, for domestic flights. Lighter, Cessna-type aircrafts can be seen there. The military/government airport is in Eastleigh district (pron: "East-Lee"), a very large residential area of housing in the east/north-east of Nairobi, but the government airport is fenced around and does not handle civilian traffic. From the center, you can take Bus #34 for 50KSH, to the international airport, from the front of the Ambassador Hotel.
[edit] By train
The city is also accessible by train, with daily arrivals and departures at the Nairobi Railway station. The trains go east to Mombasa and west to Kisumu. There are 3 classes: First, Second and General. First and Second are sleepers. First have 2 seats in a cabin, Second have 4. In Second Class genders are separated unless you purchase the entire compartment of 4 seats. First-class includes bedding, breakfast, and dinner all-inclusive for around $50; Second is $35 all-inclusive. Both can be purchased without bedding or food. Tickets have to be booked through the office on Station Road in south-central Nairobi, or online.
[edit] By bus
Kenya’s bus system is mostly reliable. There are many bus companies that have routes going to and from the country’s different cities, including Nairobi, the center of the bus network.
[edit] By matatu
Matatus (14-18 seater minibuses) and shuttles (6-seater cars) are convenient, inexpensive (and often the only) modes of public transport connecting Nairobi to towns and tourist destinations in the Rift Valley and Central Highlands such as Naivasha, Nyeri, Nanyuki, Isiolo, and Thika. Matatus can be obtained from the River Road area.
Exercise extreme caution in this area: petty theft is a major concern, and valuables such as mobile phones and wallets should not be prominently displayed here, particularly after dark and even while in the matatu (see safety section below). The best method of connecting to a matatu is to arrange for a taxi to drop you off and pick you up directly at the location of the matatu that you are boarding or alighting from. If you're boarding a matatu from Nairobi, tell the taxi driver your destination and they will drop you off at the correct location. If you are being picked up, then tell the taxi driver the location you're coming from as well as the matatu company that you are using (your ticket should have the operator's name). It is best to arrange for a taxi from the hotel you're staying at. Matatu prices can cost anything from 200 KSh (matatu to Naivasha) to 450 Ksh (shuttle to Nanyuki). The price is dependent on the distance of travel.
[edit] By boat
Entry into Nairobi by boat is of course not possible, however, one could certainly arrive in Kenya by boat via Mombasa or Lamu, and proceeding by road, air, or rail to Nairobi. Immigration should be processed at the port facility.
[edit] Get around
Be careful getting around Nairobi. Traffic is very bad like any other major city, but if you use common sense and a local or guide, you should be able to get where you want.
Car Hire And Rental
Car hire and rental options are available. You can hire cars with a driver(chauffeur-driven) or on self-drive basis. Nairobi car hire companies offer salons, 4x4, and safari cars.
Carefully read the rental contract to check for rules on insurance liabilities in case of accident or theft of the vehicle.
Nairobi Car Hire [1] offers good services for 4x4 and other categories of cars.
Central car hire [2] is a reliable, trustworthy, and helpful rental company based in Nairobi. Two-wheel drive and four-wheel drive vehicles are available and are well-maintained.
[edit] By taxi
Taxis are not very cheap, but will make city life easier and safer, at least at night. Always set and agree on prices before the trip, and pay afterwards. You can find taxis parked around hotels and tourist areas. The taxis tend to be marked with a yellow line on each side. Your best bet is to ask a local or at your hotel.
[edit] By bus (matatu)
A matatu (public minibuses/commuter buses) is typically used for traveling between downtown Nairobi and the suburbs. Matatus vary in size, between the van sized 14 seat Matatus and the larger 50-seat buses. While generally safe, you should be aware that matatus are involved in a high number of accidents every year. Matatus are often overcrowded, with more people than seatbelts and therefore can be dangerous if involved in accidents. Because there are no licensing requirements, matatus are often poorly driven, with drivers passing on curbs, speeding, or passing in oncoming lanes while cars are oncoming.
On each bus is a conductor who will hang out of the matatu and call out a price (usually between 10ksh and 40ksh) and location the matatu is driving. Recently, the government has decided to ban the 14-seat matatus inside Nairobi, effective January 2011 in hopes of reducing traffic and accidents in town (which is actually not in effect since 2011-2013, that is until now). The best choice is probably the Double M Commuter Buses or the City Hoppa bus service and of late, the revived Kenya Bus Service. Beware of traffic jams on the large motorways, not only in the rush hours.
[edit] By foot
Walking around Nairobi is fairly easy since the city is small and places are easy to get to. However, there are some areas within the city where tourists should not go; minimise walking around at night. Thugs are rampant in many areas.
[edit] By road
Car hire from the airport is possible, and fairly painless with prices in line with other African countries. In the recent past, Nairobi had a severe car-jacking problem, but because of increased police check-points, it has become marginally safer. Travelling during the day reduces your chances of getting car-jacked, as most car-jackings occur after dark.
[edit][add listing] See
Nairobi is known as the safari capital of Africa, however the city has still managed to keep up with modernization. Unlike other cities, Nairobi is surrounded by 113 km² (70 mi²) of plains, cliffs and forest that makes up the city’s Nairobi National Park. The city is filled with many things to do during the day and the night. Tourists can have their pick from numerous safaris (wildlife, cultural, sport, adventure, scenic and specialist), ecotourism tours, restaurants, culture, shopping and entertainment. While in Nairobi, tourists can also engage in numerous sports from golf, rugby, athletics, polo, horse-racing, cricket and football (soccer).
• Nairobi National Park, just outside Nairobi. This is home to large herds of Zebra, Wildebeest, Buffalo, Giraffe, Lion, Cheetah, Hippo, Rhino and even birdlife (over 400 species). Here you can also go on the Nairobi Safari Walk, an educational centre to make people aware of wildlife and habitat conservation. Also in the park is the Nairobi Animal Orphanage.
• Sheldrick Elephant Orphanage, close to the Nairobi National Park. This Orphanage takes in elephant calves and rhinos from all over Kenya which were orphaned by poaching. Showing is only once per day from 11am-12pm (admission 500Ksh) and gives you a great opportunity to interact directly with baby elephants.
• Giraffe Centre, in Lang'ata right outside of Nairobi. The Centre breeds the endangered Rothschild Giraffe and has conservation/education programmes for Kenyan children. It also has many warthogs. Here you can feed giraffes by hand and even get a kiss (their tongues can get up to 20" long and are antiseptic).
• Mamba Village. Typically the 3rd stop for most tourists after the Elephant Orphanage and Giraffe Center, this pleasant park is home to ostriches and crocodiles. Surprisingly quite interesting as you get the chance to interact directly with crocodiles and even hold a baby, with very knowledgable employees serving as guides.
• Lake Naivasha. About 1.5hrs outside of central Nairobi, this area is a haven away from the chaos of the city where many 3rd and 4th generation British colonialists continue to reside. Crescent Island [3] is a particularly nice place to visit, even if you have already done a safari. Unique because it gives you the opportunity to walk around the grounds literally alongside giraffes, zebras, wildebeest, impalas, etc.
• Ol Donyo Sabuk National Park, 65 km from Nairobi, is centred around a 2,146-m (7,141 ft) mountain. This is a mountain forest and plain land, with a large population of Buffalo. It also serves as a refuge for Colobus monkeys, bushbuck, duiker, leopard, and a large variety of bird species.
• 14 Falls, a waterfall at Thika.
• Kenyatta International Conference Center (K.I.C.C), (Central District), [4]. The best place to get that far ranging view over the sprawling, congested metropolis that is Nairobi. You can go up to the saucer-shaped top of the conference centre's round viewing tower and depending on smog and fog, you might be able to see as far as the slums and the national park. 400KSH / 200KSH reduced. edit
• US Embassy Memorial Site, (Central District), [5]. In 1998 a blast rocked downtown Nairobi. A truck had exploded next to the US Embassy building, reducing it to rubble and killing 212 people some on staff, most bystanders. On the same day, August 7, the US embassy in Dar Es Salaam, Tanzania, was also subject to a similar terrorist attack. 21 people have been charged with the crime, including Osama Bin Laden. The former embassy site today contains a memorial that can be visited. edit
• Tana River, is an hour's drive from the city. White water rafting throughout cataracts, which leads to the 14 falls can be done here. The rafting trip also includes a full BBQ lunch.
• Nairobi National Museum, [6]. 8:30AM-5:30PM. Where visitors can learn about Nairobi, its history and culture. The museum celebrated 100 years in 2010. edit
• National Railway Museum, visitors can learn more about the history of Kenya’s railroads and the Kenya/Uganda railway. It also houses, some of the engines and rolling stock from the country’s colonial period.
• Nairobi Gallery, P.O.Box 40658-00100, +25420216566. This is a museum housing only special exhibits, so the featured artwork is always changing. edit
• Karen Blixen Museum, P.O Box 40658-00100, +254208002139 (). is based on the Karen Blixen’s book "Out of Africa". Her house is now the home of the museum. It is on the outskirts of Nairobi and a taxi or bus can get you to the museum. edit
• Bomas of Kenya, portrays Kenya’s culture. Visitors can see exhibits of traditional Kenyan homes, artifacts, dances, music, and song.
• Uhuru Gardens, built in remembrance of the struggle for independence, which Kenya was granted in 1963. The monument is a 24-m (79 ft) high triumphal column supporting a pair of clasped hands and the dove of peace, high over a statue of freedom fighter raising the flag. The monument is surround by fountains and lush-landscaped gardens.
• Westlands by night, Visit the bustling and hip Westlands district, which has turned into the new nightlife center of Nairobi. Many restaurants and bars line the busy Woodvale Grove and Mpaka Road. A visit to 'Tree house' club is a must if you are looking for a spacious one and crowd outnumbered with expats, rather than the otherwise congested natives dominated ones. Traffic can become hectic, well into the early hours. Security is generally tight and the action spills out from packed clubs into the street.
• Jamia Mosque, (Central District), [7]. While Jamia Mosque is tucked away in between other buildings their are striking views to be glimpsed of its intricate structure from many different angles. Easily the most impressive religious structure in the capital, the interior is off-limits to non believers edit

There are quite a number of networked banking machines in major shopping areas of Nairobi as well as the arrivals area of the airport. A Barlays ATM can be found near Gate 9 within the security area, easily accessible when arriving, and another one on the left side immediately after leaving the security area. Most transactions are cash only, so it is best to have enough cash on hand to pay for purchases and transport. Major banks such as Barclays, Kenya Commercial Bank, and Standard Bank give better exchange rates than any of the FOREX bureaus. Independent machines such as Pesa-point have lower cash limits and may have a higher fee. For example, in 2007, Barclays did not charge any additional fee for a cash withdrawal but gave a lower exchange rate than Kenya Commercial Bank. KCB charges a CDN$5 fee for a withdrawal with a maximum of 40,000/= per day.
Cash is dispensed in units of 1000/=. Note: Many smaller businesses do not have much change, so be sure to have a good selection of smaller notes before going shopping for curios.
Forex Bureaus are located in many parts of the city where tourists are common. They will exchange cash of different currencies, and may also accept a personal cheque for Kenyan cash. They will want a photocopy of your passport before they exchange money. Rates are not bad, but will be worse than a banking machine will offer. Be aware that many exchange bureaus and hotels will NOT accept or exchange American currency printed before 2000. When the exchange bureaus do accept pre-2000 notes, they typically offer substantially lower exchange rates than for curreny printed after 2000. Exchange rates are also typically lower for small denomination currency than for $100 and $50 bills.
Credit Cards Many specialty stores accept international credit cards, however they normally tell you up front that they will charge you bank fees, typically 5% of the purchase. The Nakumat and Uchumi supermarket chains would accept credit cards without a surcharge.
This may also be a good place to repeat the warning about safety: Pickpockets are rampant in Nairobi and have been known to keep an eye on people getting cash from a machine. It is best to carry cash in a hidden pouch rather than a wallet. Men: do not carry your wallet in your back pocket, and women: do not carry your purse to your side or behind you, particularly in busy locations.
The four primary supermarkets in Nairobi are Tusky's, Uchumi, Naivas and Nakumatt. For goods beyond supermarket fare, try Yaya Centre on Argwings Kodhek Road in the Kilimani area, The Junction on Ngong Road, or the Sarit Centre and Nakumatt Westgate which are both located in the Westlands suburb.
The Sarit Centre will be recognizable to any Western traveller as a shopping mall, with an Uchumi supermarket inside. Clothing, shipping, and Internet are all available here. In addition, there is a small movie theater. Other malls in Nairobi include Yaya Centre near Hurlingham and The Mall in Westlands.
Nakumatt Westgate is a just finished competitor to Sarit Centre. It is a large building with many spaces for stores to move in to (they have yet to move in at the time of this writing, however the building is still unfinished). Currently, the primary occupant is the Nakumatt itself, which has modeled itself to emulate a Super Wal-Mart type experience. Any taxi driver will know these two shopping centers by name, so getting there is not a problem.
An additional smaller supermarket, catering more to expatriates, is in ABC Plaza, along Waiyaki Way. Chandarana supermarket carries a wide variety of imported goods, Zucchini greengrocer is a highly dependable spot for clean and varied veggies, and Gilani's is a well stocked western style butchery.
For local curios and souvenirs, the most easily accessible and tourist-friendly is the Maasai Market, held on Fridays at the Village Market, an upscale, open concept shopping center near the United Nations and American Embassy complexes. Bargaining is necessary, and one should probably not spend more than 1000KSh on one item, except in extraordinary circumstances. The Masai Market is also held on Thursdays at the parking lot of the Junction Shopping Center and Tuesdays at the parking lot of the Westgate shopping center. Bargain hard, and do not let that deter you from speaking with many of the friendly shopkeepers who are apt to offer gifts with no other incentives.
For slightly better prices, visit the Tuesday market in town, just down from the Norfolk hotel. This market is less secure, but is larger and offers more variety and opportunity for bargaining.
Another Nakumatt is located at Nakumatt Junction, past Lavington towards the Ngong Racecourse (Horse Flat-Racing takes place 3 Sundays a month, and is a great way to spend an afternoon). The Nakumatt Junction shopping complex features a few more boutiques - one of note being Zebu, a store highlighting local Designer Annabelle Thom's leather bags and more, where you will find higher quality and higher prices for beautiful designs.
Biashara Street, located downtown, is the spot for textiles. Make sure you pick up at least one kikoi or kikoy (a traditional wrap for Swahili men, predominantly at the coast). Haria's Stamp Shop (been around for more than 70 years!) (www.hariastamp.com) has one of the best selections of kikoy as well as other african fabrics and souvenirs.

[edit] Mid-range
Nairobi has a fantastic array of mid-range eateries.
Open House [9] is an excellent Indian restaurant nearby Westlands area of Nairobi. With such a high predominance of Indians in the country, this is one of the best places to get authentic cuisine in an upscale environment at a reasonable price. Do not miss the ginger chicken wings - very unique!
Mesob is an authentic Ethiopian restaurant located at the China Centre on Ngong Road near the Chinese embassy. Meals cost around Ksh 500 and the food is excellent.
Java House, with quite a few locations, including The Junction, ABC Place, and close to the United Nations, features a western coffee house menu, from bagels to burritos, with excellent coffees and milkshakes, and a full breakfast menu. 500KSh-750 for a complete meal. Another popular coffeehouse is Dormans
Trattoria is an Italian restaurant. Do not expect anything decent when it comes to the mains (all around 700KSh). However, there is a fabulous and extensive dessert menu, including crepes, tiramisu, souffle, and a coffee granita with fresh cream (250KSh-500).
Motherland, is an authentic Ethiopian restaurant with great and affordable food (typical of Ethiopian restaurants in Nairobi!).
Havana Bar, Woodvale Grove, Westlands. Popular bar and restaurant with a laid-back Latin theme. Renowned for their sizzling Fajitas, steaks and seafood dishes. Reasonably priced. The kitchen is open daily from noon til late. [10] Tel: 020-4450653

Nairobi has a wide range of Indian restaurants that speaks to the significant South Asian community in Kenya. The city also offers other restaurants specializing in different European and Asian cuisine.
Common fast food restaurants include Steers, Debonairs, Wimpy, Galito's, local favourite, Kenchic among others.
In addition, there are several local restaurants that cater to local cuisine like sukuma wiki (green spinach-like vegetable, 'Kale' in English), ugali (corn bread, ground maize flour and made to a tasty white bread/porridge form), nyama choma (lit: meat roast), chapati, and other specialties.
[edit] Splurge
The Carnivore, located just outside the city, close to the Uhuru Gardens, is a luxury restaurant famous for its meats. In 2006, the restaurant was listed as one of the top 50 restaurants in the world. Once seated, different masai grilled meats will be carried around on sticks and carved to your plate at request. Very expensive by Kenyan standards, beware of additional taxes and catering levys. Reservations might be a good idea, ask at your hotel.
Furusato, located in Westlands, has fantastic Japanese food. For a price.
The Rusty Nail, in Karen, has been super in the past, but mediocre of late. No reason not to give it another chance.
The Lord Errol, past Village Market and into Runda, is said to have very good food, and is popular with the expat crowd.
"Moonflower," on State House hill at the Palacina hotel, is a very upscale bistro / fusion / grill restaurant in a lovely outdoor setting. Fantastic food.
"Pango Brasserie" at the Fairview Hotel features upscale french and continental dishes. Dinner begins in an underground stone wine cellar where the chef will send out complimentary tasters while you sip a bottle of wine of your choice.
"Alan Bobbe's Bistro" is a venerable, legendary restaurant now located on Rhapta Road (near St. Marys School). Founded in 1962, the restaurant features French haute cuisine at about a third of what you would pay in Paris!

[edit] Stay safe
Nairobi has a reputation for thievery. Beware of snatch and grab, con artists, or groups of people following you. Scams are elaborate and can involve up to 10 or more people working together. The best advice for a tourist is to stay in the city centre, know where you are at all times, and pretend you know where you're going (even if you don't). If you find yourself in an unfamiliar area your best bet is to find a taxi (although you will probably pay dearly if the driver suspects a panicked westerner!). Don't carry large quantities of money or passports on the street, and assume that anyone trying to engage you is up to no good or trying to sell you something. In recent years, crime has significantly reduced, though one should still be wary. If one stays smart and plays safe, without going around much after dark, Nairobi is a safe place to stay. Most locals are honest people who will happily help you if you approach them.
Kenyans are proud people and there is not a lot of begging like you find in some other countries. Some opportunistic people will hang around shopping centres and beg, but they will generally accept a simple 'sorry' and leave you alone if you do not give. Many of these 'beggars' are middle class kids or adults who have realised they can profit from exploiting foreigners, and should not be encouraged. If you are ever lucky enough to visit a slum as a local (not on some perverse tourist safari) you will discover the poorest of the poor do not even beg.
Outside of tourist and expat communities, young children will become excited at the sight of foreigners. If you are fair-skinned, children may run towards you to try to shake your hand, or yell "mzungu" (white person) or "how are you?". Older kids are more reserved, and you should be wary of kids who are older than 9 or 10 who are trying to distract or get close to you.
Slums should be avoided by tourists as you will attract a lot of attention which can quickly turn into a dangerous situation.
Apart from the inner city centre, Nairobi dies out at night. Streets are mostly empty. Do not walk alone after nightfall. Always use taxis. The areas north and east of River Road should be avoided, especially if you're not a local!
Biashara Street is a safe shopping street due to the presence of 10-15 Maasai guards. A place to avoid as a tourist is the City Market; you could end up paying a much higher price than on Biashara Street.
If you are in a matatu and moving slowly through traffic, particularly after dark, you should keep your window closed if your valuables are in reach to prevent people snatching them from the outside (there are thieves who walk through traffic looking for such opportunities). Mobile phones and wallets should be securely kept and not displayed prominently during calls or cash transactions in the River Road area, particularly after dark.
Eastleigh (known as 'little Mogadishu') is an area near the city centre that is decaying due to years of neglect by the government (including the police). It is predominantly populated by Somalian migrants and refugees, and most Kenyans will not go there for fear of their safety. Tourists would be wise to avoid it day and night.
There have been several grenade attacks in the city for which Al-Shabaab have claimed responsibility. These are likely to be ongoing while the Kenyan army has a presence in Somalia. They are random and often fatal, and one should be weary and report any suspicious behaviour.
[edit] Stay healthy
It is recommended that before tourists come to Nairobi, that they should be vaccinated well in advance (6 weeks) of their trip. The most common recommended vaccines for people traveling to Africa are Tetanus, Diphtheria, Polio, Typhoid, Hepatitis A, Hepatitis B, Yellow Fever, Rabies and Meningitis.
[edit] Food and beverages
Be careful with the food that you eat outside the more upscale establishments. Before eating, make sure that the food is freshly and thoroughly cooked and served hot. Also avoid seafood,apart from the upmarket restaurants and hotels, and make sure that your fruits and vegetables have been properly sterilized in clean water. The safest fruits to eat are bananas and papayas. Do not drink tap water or brush your teeth with it. Only use bottled or canned drinks (especially popular brands). Also, do not use ice as it may also be contaminated water, and remember that alcohol does not sterilize a drink. The general rule of thumb is, the more high end an establishment is, the greater the safety of the food and drink within.
[edit] Insects
In Africa you are going to be exposed to yellow fever, dengue fever, other viral diseases, sleeping sickness, filariasis and malaria, although none of these diseases are a concern in Nairobi itself. When insects are biting you should cover up and wear long-sleeved shirts and trousers, socks and pyjamas especially when night falls. It is best to use an insect repellent that contains DEET on your exposed skin and clothing. As for mosquito nets, it is best to use a permethrin-impregnated net along with an insecticide such a pyrethrum coils or an electric mosquito killer during the night. And remember to spray your hotel room every evening.
[edit] Heat & Sun
Make sure to drink plenty of fluids (not coffee, alcohol or strong tea) to avoid dehydration. The average temperature is around 25 C (maximum might reach 30 C) throughout the year. Try to avoid plenty of physical exertion and try to stay in the shade and keep cool as much as possible. Increase the amount of salt intake in your food and water. Also, apply a lot of high factor sunscreen, avoid direct sunlight, and try to wear a hat and shady clothing.
[edit] Contact
There are very many internet cafés around Nairobi, but connection speeds and computers are not always super fast, but still you will manage to open your email, probably even use a webcam or watch YouTube. Prices are usually at ranges from 0.5KSh/minute to 1KSh/minute, usually with a minimum fee of 5-20KSh. The more expensive internet cafés are rarely better and the best ones charge 1KSh/minute with discounts for using the internet for longer. Most of the good cafés are found in Norwich Union which has quite a number just opposite Hilton Hotel next to Nandos while the expensive ones are found in malls in Westlands. Although it may be more appropriate for tourists to use the ones in Westlands since they are usually less crowded and are more exclusive but not necessarily faster or better in terms of equipment.
Free wireless internet is available at Java House restaurants and Doorman's coffee shops in the city and malls. Some bars like Havana in Westlands also offer free wifi. The internet cafe in Sarit Centre also has wireless internet available at a good speed and a reasonable price.
Mobile Phones are ubiquitous in Kenya with fairly good coverage from all providers (Safaricom, Orange and Airtel) that extends to most populated parts of the country. Safaricom has the best national coverage especially if you are using 3G data. The phone system is GSM 900 and 3G 2100 (Asian and European standard). Phones and SIM cards are available at many locations throughout Nairobi and the country including at the airport. Phone prices are very competitive and priced for average income Kenyans. A basic phone may be obtained new from an independent dealer for ~2000/=. A vast majority of people use pre-paid phones with scratch-card top-ups available at a huge number of merchants across the country. All phones are sold "unlocked" for use on any network. Much business is conducted via mobile phone, so possession of one for even a relatively short stay in the country can be beneficial. Rates are extremely affordable with in-country calls at around 3/= per minute. Overseas calls cost around 5/= per minute to the United States (~USD$0.06/minute) and 3/= per minute to India (~INR 1.80, USD 0.04) on the Airtel network.
3G data service is available in most coverage areas on Safaricom and is of a fairly high standard. The other networks have 3G in major population areas and EDGE/GPRS everywhere else. If you have a smart phone you should buy a data pack (200mb, 500mb or 1.5gb) or your credit will go down very fast!
[edit] Cope
Smoking is against the law out on the streets in the city center (the downtown grid area with numerous skyscrapers). There are certain smoking zones, and outside of the city center it becomes much easier to find locations where it is acceptable. However, a general rule would be to not smoke along the side of any roads or streets with pedestrians and/or vehicles. Be observant and take your cues from other smokers - if there are no smokers or cigarette butts on the ground, it is likely a non-smoking location.

[edit] Get out
Lake Naivasha is worth at least a day's visit and has enough to keep you occupied for two or three days. Lakeshore country clubs are a good place for lunch. You can take a boat ride on the lake to see hippos, go for a walk among zebra and giraffes on Crescent Island, ride thoroughbred horses among zebra, giraffes and wildebeest at the Sanctuary Farm, and ride bicycles among wildlife and dramatic scenery at Hell's Gate National Park.
Further afield, Nakuru National Park deservedly warrants a 1-night stay for a late-afternoon and early-morning game drive.

UNDERSTANDING AGRICULTURAL EXPORTS DATA
INTRODUCTION
The Australian Bureau of Statistics has had a long history of producing international trade statistics. These are used by economic analysts and policy advisers to monitor, evaluate and forecast developments in Australia's external trade and the general level of economic wellbeing. However, measuring the importance of this trade has, for the agricultural industry, become increasingly difficult and complex as the economy develops.
In relation to agricultural production and exports this article illustrates how different classifications, methodologies and assumptions can be used with the same body of data to provide quite different outcomes, depending on the perspective from which users wish to view the data, and the purpose of the analysis. Like most economic statistics, agricultural export and production data are based on underlying assumptions relating to industry and commodity classification, as well as market and business functions. In addition, the methodology used in collecting export data from customs records introduces its own set of limitations.
The article seeks to provide an understanding of the most appropriate methods available for comparing agricultural production with exports. The year selected for the comparison is 1997-98; however, due to fluctuations in agricultural production, overseas market access, availability of stocks etc., any comparison undertaken on the basis of a single year needs to be treated with caution.
Background
Since settlement a proportion of Australia's agricultural output has been exported. Initially, measuring the importance of agricultural exports was relatively straightforward as most of the exports were in raw form, and could be easily identified and compared with agricultural production. However, as the Australian economy developed, proportionally more agricultural output was exported in a processed or manufactured form, such as processed meat products, wine and woollen products.
In situations where agricultural production is directly exported as a raw or unprocessed product one can compare production quantities or values with export quantities or values for individual commodities, although in comparing values one needs to take account of the differences between the valuation basis for production ('farm gate') and that for exports ('free on board' (f.o.b.)). Difficulties arise, however, for those agricultural commodities which have undergone some manufacturing process and are indirectly exported as part of the manufactured product. For example, how might analysts compare the value of grape production with the value of a transformed agricultural product such as wine?
Making legitimate comparisons between production and trade is further complicated by the variety of trade data available. ABS merchandise trade data can be manipulated and grouped in a number of ways by both the ABS and external clients, depending on the use being made of the data.
Agricultural export statistics
The ways in which agricultural export data can be presented include:
• a commodity based approach
• an industry based approach
• a balance of payments approach
• an input-output approach
• an embedded commodities approach
These approaches are discussed below.
Commodity based data
For exports, the ABS uses the Australian Harmonised Export Commodity Classification (AHECC). The details and descriptions of the statistical codes of the AHECC are identified in the Australian Harmonised Export Commodity Classification (1233.0).
Commodity-based trade data are useful for monitoring changes in levels of trade over time. For example, for a particular commodity, or group of commodities, monthly or yearly data can be compared to provide an accurate picture of changes in the levels of those commodities exported. However, commodity based trade data alone should not be used to measure the complete proportion of agricultural output which is exported. This measure offers no method of calculating the agricultural component in exported processed goods.

In analysing table S4.1, the following points should be noted:
• Many commodities (e.g. wool) can draw on stocks accumulated in previous years, which can distort yearly comparisons of exports and production.
• Unprocessed commodities only are shown. Any embedded agricultural output contained in processed goods, such as meat, sugar, canned fruit, processed wool, woollen products, wine etc. are not included. In other words, the table shows only direct exports of agricultural commodities.
• Different valuation bases are used for measuring production and exports. Value of production is the gross value received by the farmer at the market place, which in general is the metropolitan market in each State and Territory. Exports are valued at the point of export (f.o.b.), and therefore include any distributional and marketing costs incurred up until the point of export.
Industry based data
Export data are also available on an 'Industry of origin' basis. The Australian and New Zealand Standard Industrial Classification (ANZSIC) is the standard classification used by the ABS for the presentation and analysis of industry statistics. It provides a framework for classifying businesses to industries according to the predominant activities undertaken by a business.
The classification is used in international merchandise trade statistics to provide an indication only of the industry which is determined to have produced the goods which are exported or imported. This is undertaken by allocating AHECC items to the ANZSIC industry which is considered to have ultimately produced the commodity. Any agricultural commodity that has undergone any form of processing is, under the ANZSIC classification system, coded to the manufacturing industry.
Therefore while raw cows' milk production is classified to the Agricultural ANZSIC Class 0130 'Dairy cattle farming', the sale of pasteurised liquid whole milk would be classified to the Manufacturing ANZSIC Class 2121 'Milk and cream processing'.
In addition, any exported items that have confidentiality restrictions on the publication of value details are not classified to their industry of origin, but are instead included in the category 'Other industries'. In 1997-98, no exported commodity items that would be allocated to agriculture under the 'Industry of origin' classification had confidentiality restrictions, but this is not always the case.
Table S4.2 shows data for exports emanating from agriculture on an 'Industry of origin' basis, and data for production from agricultural holdings classified to those ANZSIC industries. The production data shown for each Agricultural class relate to the total value of agricultural production from holdings that are primarily involved in the activity to which the class relates. For example a holding that is primarily involved in vegetable farming would be classified to the ANZSIC Class 0113, 'Vegetable growing'. The value of production data for that holding which is attributed to Class 0113 includes the value of all agricultural commodities produced by that holding, which may include commodities such as livestock, fruit and other non-vegetable crops. However, the export data for that holding would be classified on an 'Industry of origin' basis and any non-vegetable commodities exported from that holding would be classified to a different ANZSIC class.

Table S4.2 suffers from the same limitations as the data in table S4.1, in that a run-down of stocks can influence export levels and only direct agricultural exports are included. It is important to realise that the production and export data in tables S4.1 and S4.2 are derived from the same source, but that table S4.2 is classified on the basis of industry rather than commodity.
Balance of payments exports data
The balance of payments (BOP) exports data are based on international trade statistics, adjusted where necessary for timing, coverage, classification and valuation in order to meet the change of ownership conventions and classification requirements contained in the international statistical standards for BOP statistics. For example, wool exported to stockpile abroad before being sold will be excluded from the BOP when shipped, but included when sold. The ABS publication Balance of Payments and International Investment Position, Australia, Concepts, Sources and Methods 1998 (5331.0) provides a detailed description of balance of payments methods.
The broadest level commodity breakdown for general merchandise goods credits (exports) shown in BOP is 'Rural' and 'Non-rural', followed by more detailed commodity dissections within those groupings. Allocation to these groupings is largely in terms of Section(s) or Division(s) of the Standard International Trade Classification (SITC). This commodity breakdown was adopted by the ABS in the early 1960s in response to user demand.

Source: International Trade in Goods and Services, Australia (5368.0).
The category 'rural goods' is broad, and attempts to provide an indication of those exports most closely associated with the agriculture, forestry and fishing industries. For example, while meat and meat preparations, cereal preparations, canned fruit salad and timber boards are all classified as 'rural goods', beverages (including wine) are excluded. Non-rural exports, therefore, can include agricultural production embedded in other products. Because of this, and because of different valuation bases, BOP and production data cannot be directly compared.
Input-output based data
Input-output tables show the flows of inputs into and outputs from each industry for a country's entire production system for a given period. In doing this, input-output tables identify which goods and services are produced by each industry and how they are used (for example goods and services used in the production of more goods and services, or goods and services consumed by final consumers). The tables are based on the principle that the value of the output of each industry can be expressed as the sum of the values of all inputs to that industry, including any profits made. All exports data used in input-output analysis undergo some transformation, including conversion from an f.o.b. basis to a basis of 'basic prices' (for agriculture, basic prices are those received at the 'farm gate'). This has the effect of removing transport and distribution margins, and product taxes, from the export values so that the values are consistent with those received by producers. Similarly, agricultural output is also valued at basic prices in input-output tables.
Input-output tables are produced using the Input-Output Industry Classification (IOIC) and the Input-Output Product Classification (IOPC). These classifications have been specifically developed for the compilation and the application of Australian Input-Output tables. Additional information on input-output tables can be found in Australian National Accounts: Input-Output Tables (5209.0)
Value of exports from an industry
Input-output tables provide a means of tracing flows of goods and services step by step through the production process, and this information can be used to calculate the contribution made by various industries to the final value of a commodity. It is therefore possible to derive the value of the output from the agricultural industry which is embedded in products produced by other industries, and therefore to derive the value of agricultural output contained in exports of these products. This is illustrated in table S4.4.

Table S4.4 shows that $7.9b of agricultural output is exported indirectly through the export of processed products. For example, much food, which is a basic output of agriculture, requires some processing before being exported. From table S4.4 it can be seen that indirect exports from the beef cattle industry ($1.9b) are more than direct exports ($312b). On the other hand, direct exports of grains ($4.0b) are more than indirect exports from the grains industry ($1.3b).
From table S4.4 it can be established, using the input-output approach, that the total value of agricultural production exported directly or indirectly in 1997-98 was $14.5b. It is important to realise that a number of factors, such as run-down of stocks, weather conditions and changes in the availability of export markets, mean that this is a short period on which to make long term judgements on the overall level of agricultural output exported.
In addition, certain basic assumptions apply when analysing both direct and indirect exports estimates calculated using the input-output approach. These are:
• Commodities exported from a particular industry consist of the same quality and content as those sold on the domestic market. It follows that, if the proportion of agricultural output embedded in an exported processed food product is significantly different to the average for that product, any estimate of the value of agricultural output exported will be deficient to that extent.
• Export prices are similar to domestic prices for the output of a particular industry. It follows that, if prices paid for output which is indirectly exported are significantly higher than domestic prices, the value of output exported indirectly would be underestimated.
Proportion of industry output exported
Estimating the proportion of total agricultural output which is exported adds further complexities.
The simplest approach would be to use the value of production shown in table S4.4 as the denominator. Doing so provides an estimate of approximately 51% for 1997-98. This estimate has been calculated without making any adjustments for agricultural output that is subsequently consumed within the agricultural industry. If such adjustments are made, a similar estimate is derived because, using the input-output approach, the reduction in the value of agricultural output is almost exactly offset by a proportional reduction in the value of indirect exports. However, for certain analyses it may be appropriate to deduct from the estimate of value of production the value of livestock produced for breeding purposes (on the basis that this production is not available for sale until the livestock is slaughtered) and the value of commodities produced for own account consumption (on the basis that this production is not available to the market). If both of these adjustments are made, the proportion of agricultural output that is exported under the input-output approach rises to about 56%.
Embedded commodities approach
This approach estimates the volumes of agricultural commodities contained in indirect exports using factors which calculate the percentage of raw product contained in various processed goods. These volumes are then added to the volumes of direct exports of agricultural commodities. The value of exports for any commodity is derived by multiplying the gross unit value received by farmers for that commodity by the volume of product exported.
When this method is used, production estimates need to be adjusted to remove production used within the agriculture industry, in order to derive the denominator necessary to calculate the proportion of agricultural output that is exported. The denominator can also be adjusted to take account of the value of livestock produced for breeding purposes and commodities produced for own-account consumption. Using this approach, the Australian Bureau of Agricultural and Resource Economics (ABARE), has estimated that the proportion of agricultural output exported in 1997-98 was approximately 65%.
Conclusion
Analysis of data about the exports of agricultural commodities requires an understanding of the concepts, classifications and methodology.
This article illustrates that the value of agricultural output finally exported is very much influenced by the value of agricultural output included in processed exports. For example, table S4.4 shows that, using the input-output approach, the percentage of output exported from the beef cattle industry increases from 8% (direct exports), to 58% (direct and indirect). Equally importantly, this article shows that the assumptions used in defining agricultural output and exports, and the methodologies used to derive these estimates, can also affect results, and users need a basic understanding of these methodologies in order to interpret the data effectively.
Given the variety of methodologies used to estimate exports and production, and the assumptions required to use these methodologies, any estimate of the proportion of agricultural output which is exported will only be an approximation, and should not be interpreted as an exact result. Finally, while this article presents some illustrative estimates in respect of 1997-98, agricultural production and exports of agricultural commodities can vary from year to year, and users are cautioned about making firm conclusions based on only one year's data.

PASTURES AND CROPS IRRIGATED
Australia
Australian irrigating agricultural businesses applied 18% less irrigation water to agricultural land in 2007-08 than the previous year. The area irrigated nationally decreased 4% to 1,851 thousand hectares.
The rice industry showed the effects of dry conditions and limited irrigation water with only 23 rice producers using 27 gigalitres of irrigation water, a drop of 89%. This drop in application of irrigation water follows the 81% reduction in 2006-07.
Cotton growers faced similar conditions in 2007-08 and applied 309 gigalitres of irrigation water to 58 thousand hectares. This was in comparison to the 868 gigalitres used for irrigation and 134 thousand hectares irrigated in 2006-07.
State/Territory
While in 2006-07 cotton growers were the primary users of irrigation water in New South Wales, accounting for 26% of irrigation water use, in 2007-08 the major irrigators were irrigating other cereals for grain or seed, using 34% of all irrigation water applied. The area of cotton crop irrigated in New South Wales fell 62 thousand hectares (63%).
The volume of water applied to grapevines nationally dropped from 639 gigalitres in 2006-07 to 517 gigalitres in 2007-08. Victoria accounted for over half of this reduction, with water used on grapevines declining to 153 gigalitres. Pasture, cereal and other crops for grazing used the majority of Victoria's irrigation water (50%), irrigating 221 thousand hectares at an application rate of 3.0ML/ha.
Whilst reporting a downturn in area under crop, sugar cane producers continued to be the largest irrigator in Queensland, using 45% of the state's irrigation water at an application rate of 4.5ML/ha. Queensland saw a large increase in irrigation of other cereals for grain or seed (327 gigalitres).
In 2007-08, pasture, cereal and other crops used for grazing was the major use of irrigation water in South Australia, Western Australia and Tasmania, accounting for 32%, 35% and 62% of irrigation water applied in each state respectively.
Grapevines were the second largest irrigation water consumers in South Australia (23%) in 2007-08. The second largest irrigators in Western Australia were fruit tree, nut tree, plantation or berry fruit producers, irrigating 67% of the area of these crops, at an application rate of 4.7ML/ha. In Tasmania, 44 gigalitres of water was applied to vegetables for human consumption or seed, the second largest irrigated agricultural area in the state at 14 thousand hectares.
Irrigation of fruit trees, nut trees, plantation fruit or berries in the Northern Territory continued to decline from 13 gigalitres in 2006-07, to 7 gigalitres in 2007-08.
Murray-Darling Basin
The area of agricultural land irrigated in the Murray-Darling Basin continued to decrease in 2007-08, to 958 thousand hectares, with 30% less irrigation water being applied than in 2006-07. These drops follow the declines of 2006-07 where the area irrigated fell 33%, and the volume of irrigation water applied fell 40%.
In contrast, irrigation water use outside the Murray-Darling Basin decreased much less in both years, down 1% between 2006-07 and 2007-08, following on from a decline of 6% between 2005-06 and 2006-07.
All of Australia's rice producers were located in the Murray-Darling Basin in 2007-08, and the impact of limited irrigation water was seen at the national level. Similarly, 92% of Australia's cotton growers are located in the region, irrigating 81 thousand hectares (60%) less land than in 2006-07.
In 2007-08, other cereals for grain or seed accounted for the highest proportion of irrigation water in the region (26%) followed by pasture, cereal and other crops for grazing (21%) and grapevines (14%).

MINING
Mining broadly relates to the extraction of minerals occurring naturally as solids such as coal and ores, liquids such as crude petroleum, or gases such as natural gas. Activities carried out at or near mine sites as an integral part of mining operations, such as dressing or beneficiation of ores or other minerals, are included. Natural gas absorption and purifying plants are also included. However, the first stage processing of minerals and mineral extracts, while closely related to the mining industry, is included as part of the manufacturing industry.
Australia continues to rank as one of the world's leading mining nations with substantial identified resources of major minerals and fuel close to the surface. In 2006 it had the world's largest economic demonstrated resources of brown coal, lead, mineral sands (rutile and zircon), nickel, tantalum, uranium and zinc.
Australia was the largest producer of bauxite, mineral sands (ilmenite, rutile and zircon) and tantalum in 2006. It was also one of the largest producers of uranium, iron ore, lead, zinc and nickel.
The contribution of the mining industry to Australia's gross domestic product remained around 4-5% over the period 1996-97 to 2004-05 but increased to 7% in 2005-06. The mining industry is Australia's second largest export earner (after manufacturing), accounting for 37% of the total value of exports in 2006-07, principally from the metal ore and coal mining industries.
This chapter concludes with the article Sustaining the mineral resources industry - overcoming the tyranny of depth.

Abstract
Background
In the last decade, techniques were established for the large scale genome-wide analysis of proteins, RNA, and metabolites, and database solutions have been developed to manage the generated data sets. The Golm Metabolome Database for metabolite data (GMD) represents one such effort to make these data broadly available and to interconnect the different molecular levels of a biological system [1]. As data interpretation in the light of already existing data becomes increasingly important, these initiatives are an essential part of current and future systems biology.
Results
A mass spectral library consisting of experimentally derived tryptic peptide product ion spectra was generated based on liquid chromatography coupled to ion trap mass spectrometry (LC-IT-MS). Protein samples derived from Arabidopsis thaliana, Chlamydomonas reinhardii, Medicago truncatula, and Sinorhizobium meliloti were analysed. With currently 4,557 manually validated spectra associated with 4,226 unique peptides from 1,367 proteins, the database serves as a continuously growing reference data set and can be used for protein identification and quantification in uncharacterized biological samples. For peptide identification, several algorithms were implemented based on a recently published study for peptide mass fingerprinting [2] and tested for false positive and negative rates. An algorithm which considers intensity distribution for match correlation scores was found to yield best results. For proof of concept, an LC-IT-MS analysis of a tryptic leaf protein digest was converted to mzData format and searched against the mass spectral library. The utility of the mass spectral library was also tested for the identification of phosphorylated tryptic peptides. We included in vivo phosphorylation sites of Arabidopsis thaliana proteins and the identification performance was found to be improved compared to genome-based search algorithms. Protein identification by ProMEX is linked to other levels of biological organization such as metabolite, pathway, and transcript data. The database is further connected to annotation and classification services via BioMoby.
Conclusion
The ProMEX protein/peptide database represents a mass spectral reference library with the capability of matching unknown samples for protein identification. The database allows text searches based on metadata such as experimental information of the samples, mass spectrometric instrument parameters or unique protein identifier like AGI codes. ProMEX integrates proteomics data with other levels of molecular organization including metabolite, pathway, and transcript information and may thus become a useful resource for plant systems biology studies. The ProMEX mass spectral library is available at http://promex.mpimp-golm.mpg.de/ webcite.
Background
Large-scale protein analysis is closely linked to mass spectrometric techniques. Peptide fragmentation in an ion trap mass spectrometer (IT-MS) is one of the most used approaches for protein identification in complex samples [3]. One such technique, referred to as "shotgun proteomics", can be exploited for rapid screening and – in combination with further fractionation – comprehensive qualitative protein identification in complex samples [4,5]. Proteins are extracted from tissues and analysed after separation on gel electrophoresis or directly via tryptic digestion. Thousands or tens of thousands of peptide mass spectra are generated in a typical analysis. For high throughput identification, these mass spectra can be matched against theoretical amino acid sequences derived from the annotated or predicted proteome of an organism. However, in many of the available algorithms, only the appearance of specific mass fragments in a CID-MS, but not their intensity distribution is considered specifically, because it can not easily be predicted from the amino acid sequence of peptides alone. Therefore, the approach of establishing a mass spectral reference library as used routinely in metabolic and metabolite profiling by gas chromatography coupled to mass spectrometry appears promising [6-8]. We investigate here the utility of a mass spectral reference library by implementing a database consisting of 4,557 manually validated tryptic peptide product ion spectra of divers plant proteins generated by LC-IT-MS and mass fragment intensity correlation search for protein identification.
Construction and content
Creation of the mass spectral library
A library of 4,557 manually validated peptide/phosphopeptide product ion spectra from approximately 330,000 collision-induced dissociation (CID) fragment spectra analysed in various LC-MS/MS analyses from recent studies was generated [4,5,9-12]. These CID spectra were annotated with Sequest and Mascot using the filter and search criteria as described in these studies [4,5,9-12]. In addition to the filtering, the resulting spectra were further validated manually using the SILVER web application [13].
ProMEX database system
ProMEX was designed as a web-based service in a Linux/Apache environment using Perl-CGI for HTML page generation. A Microsoft SQL Server 2005® was utilised as the relational database backend for storing the library spectra as well as the query spectra uploaded by the user. Algorithms for comparing spectra to identify matching hits were implemented using the Common Language Runtime (CLR) .Net framework using the C# programming language. Library mass spectra as well as user-uploaded query spectra are saved using a User-defined Data Type (UDT) in the database permitting us to calculate the score values directly within the database by using standard T-SQL to access the spectra. Using indices to select matching library spectra according to a given precursor ion mass and a charge state of a user-submitted product ion spectra and taking advantage of the server's memory management system, we achieved high performance and efficient memory usage.
Because of the server's limitation of the UDT size to 8,000 Bytes, it was necessary to limit the product ion spectra to maximally 1,000 fragment peaks each (1,000 peaks with 4 Byte m/z and 4 Byte intensity each). Upon evaluating the intensity distribution (Figure 1), we assessed the dependence of the identification process on the level of noise removal; i.e. peaks with very low intensity. Applying the receiver operating characteristic (ROC) analysis, peptide identification accuracy was observed to be robust with regard to noise filtering and a level of 2% relative peak intensity was chosen as a conservative threshold for noise removal (Figure 2).
Figure 1. Peak intensity distribution from product ion spectra. 70% of all fragment peaks have a relative intensity less or equal 0.02. The peak on the right hand side originates from the prior scaling of all spectra to a maximum peak intensity of 1.
Figure 2. Assessment of the effect of noise removal on the identification performance illustrated by the receiver operating characteristic (ROC). The identification rate is robust against different levels of peak noise filters up to 10%. We decided to use a conservative noise removal level of 2%. Recall (true positives) reflects the number of correctly identified peptides based on SEQUEST search, whereas 1 specificity corresponds to all ProMEX peptide identifications which did not match to the SEQUEST identifications. As a comparison, results from using the Euclidean distance are also included which proved to be inferior to the dot product.
As described in [2], the performance of peak-list comparison is influenced by several factors, most importantly by the choice of the distance measurement itself. Here, we found a modified dot product [7] distance measure
to perform best on the mass spectra used in this study where x and y denote the two spectra to be compared, are the mass-charge ratios and are the normalised intensity values of the i-th peak in the spectrum x, likewise for spectrum y and index k. A and B are the total number of peaks in the spectra x and y, respectively. The term
is a windowed, linear weighting factor accounting for the match accuracy with regard to mass-charge ratio difference of fragment peaks xi and yk where a corresponds to the fragment ion mass tolerance specified by the user. The same strategy was applied in a recent mass spectral match algorithm [2]. Because all peaks are normalised to
where I refers to the raw intensities of a given spectrum with l peaks including only those peaks above the noise threshold discussed above, D is always within the range of (0, 1) with values closer to zero indicating better matches between two spectra. The dot product distance is calculated looping through both MS/MS spectra x and y under comparison sorted in ascending order according to their m/z ratios and using a reference pointing to the next fragment peak for a potential fragment match for each peak list. In case the mass difference between those referenced peaks is less than or equal to the fragment ion mass tolerance a, both referenced peaks are used in Eq. 1 with their respective intensities. Otherwise a zero-intensity peak is "matched" to that referenced peak. In the first case, both peak reference pointers are incremented simultaneously, whereas only the index pointing to the peak with the smaller m/z ratio is incremented in the latter case. We iterate that loop until all peaks are checked off.
To balance flexible process parameterisation and performance of mass spectra identification, we limited the user interface to a subset of parameters (Figure 3):
Figure 3. Screenshot of the ProMEX user interface. Input can be inserted into the textbox or uploaded as file using the file selection dialog.
Precursor ion mass tolerance defines a window for considering two distinct MS/MS spectra coming from the same parent ion;
Fragment ion mass tolerance defines a window for considering two ion peaks from different peak lists as identical;
Threshold defines a threshold value to ignore mass spectra hits above this score value; i.e. spectra are not considered as matching.
ProMEX is able to handle uploads of merged MS/MS text files (dta or mgf) [14] or mzData http://psidev.sourceforge.net/ms/ webcite standard http://psidev.sourceforge.net/ms/xml/mzdata/mzdata.xsd webcite. User-uploaded data are verified and parsed using Perl, and the spectra submitted as queries to the database. Spectra contained in the library are sorted according to their matching score ignoring hits above a given score threshold value. The hit list of identified proteins is further augmented by information contained in the database including peptide annotations, information regarding the biological experiment, instrument settings as well as links to online resources of the National Center for Biotechnology Information (NCBI), the Kyoto Encyclopedia of Genes and Genomes (KEGG), and the Comprehensive Systems-Biology Database (CSB.DB) (Figure 4).
Figure 4. Screenshot of the result page showing four identified peptides associated with the candidate hit protein At1g13440 which was tagged in the sample by 8 submitted fragment spectra. For visual inspection of the spectra match, a north-south-plot of the library versus query spectra is shown below.
Considering widespread use of the BioMOBY http://www.biomoby.org/ webcite environment in web-based bioinformatics and as a common framework for biological resources, we implemented a service getTrypticPeptideSequenceByAGI that returns a list of experimentally measured tryptic peptides for Arabidopsis genes identified by their Arabidopsis Genome Initiative (AGI) code.
To obtain maximal performance and limit temporary disk space usage, all uploaded spectra, results, and session information will be deleted within 24 hours after transmittal. Using current standard hardware equipment, a typical ProMEX analysis of a 196 MB merged dta file with >30,000 MS/MS spectra is completed within approximately 13 minutes.
Utility and Discussion
Mass spectral library and experimental metainformation
A library containing 4,557 measured peptide MS/MS spectra from 1,367 distinct proteins represented by 4,226 peptides including the corresponding experimental information was created. In case of replicated fragment spectra contained in the database – a small fraction of all spectra, only the best matching spectrum is returned. In addition to existing algorithms which use mass spectral library searches such as GPM X!Hunter http://www.thegpm.org webcite or SpectraST [6], we attempted to link the identification process to experimental metainformation and quantification. The latter is facilitated by the possibility to upload complete LC-MS runs in mzData format and to search them against the database. The result of peptide/protein identifications is accompanied by a semiquantitative measure called spectral count giving the possibility to estimate the relative abundance of proteins in the sample [4,15] (see also below). Furthermore, we optimised the database search to allow analyses of large file sizes (up to 200 Mbyte and more, see below) which to our knowledge is not yet implemented in other databases. The peptide spectra presently stored in the database were mainly derived from Arabidopsis thaliana, Medicago truncatula, Chlamydomonas reinhardii and Sinorhizobium meliloti, acquired in 18 experiments through fragmentation with LCQ, LTQ or Orbitrap mass spectrometers [5,9,10,12].
ProMEX mass spectral library search of unknown samples
For the analysis of protein identification efficiency of ProMEX, LC/MS analyses were processed by both ProMEX and SEQUEST http://fields.scripps.edu/sequest/ webcite. The disadvantage of ProMEX may lie in the use of an inherently incomplete dataset compared to a genomic database. On the other hand, a mass spectral library consisting of experimentally observed and validated spectra as implemented in ProMEX can be expected to provide clear advantages over genome-based prediction of mass spectra [6].
To set a suitable default cutoff threshold for the search algorithm implemented in ProMEX, two different distance measures – the dot product and Euclidean distance – were compared by searching mzData files of LC-MS analyses against the ProMEX mass spectral library. The results were compared to the SEQUEST result file ("true positives"). Figure 2 illustrates the gain of correct predictions by the dot product in comparison to the Euclidean distance. Because of the better performance, the dot product distance was chosen and the default threshold value was set to 0.5. In Figure 5, the resulting peptide identification output was examined for the number of false hits against true positive peptide hits (list of peptides identified by SEQUEST) as a function of threshold score for the dot product distance. Using the default threshold, the false peptide detection rate was found to be less than 1%, while the number of false negatives reached a level of 25% in our dataset.
Figure 5. Comparison of peptide identification rate as a function of match score. True positive identifications are all matches found by SEQUEST and ProMEX. False positives are defined as residual peptide identifications by ProMEX which did not match to the SEQUEST hits. The default threshold value for ProMEX was set to 0.5 according to this diagram.
For 86 proteins, the list of protein identifications was identical in both systems. From subsequent searches, it became clear that the specificity for peptide identification increases with ProMEX because fragment intensity distributions in product ion spectra are taken into account as an additional parameter.
Very importantly, spectra which are not assigned by SEQUEST or MASCOT can easily be included in the ProMEX mass spectral library as unknowns. This allows recognizing these spectra again in new analyses which is not possible by using algorithms based on genome-derived theoretical mass spectra. Another potential advantage of a mass spectral reference database lies in the identification of phosphorylated peptides which usually give very ambiguous results in genome-based database searches [11,16]. For proof of concept, we included CID-MS of synthetic phosphopeptides in the ProMEX reference database which were based on in vivo and in vitro protein phosphorylation sites detected in Arabidopsis thaliana samples [11,17-19]. Subsequently, we were able to identify these phosphopeptides in a set of different plant samples. Several of these peptides were not identified reproducibly with genome-based search algorithms like SEQUEST.
Protein quantification using ProMEX
ProMEX provides a quantitative estimate for the abundance of a protein/peptide in the sample. In case a complete LC/MS run is uploaded in mzData-format the ProMEX result table has an entry for each protein/peptide how often it was identified. This measure is similar to spectral count (SC) [4,15] and has been shown to be a valuable parameter for semi-quantitative mass spectrometry analysis.
Identifying bottlenecks and limits
Setting the threshold too high or uploading LC/MS runs with large numbers of mass spectra results in computation times proportional to the number of submitted spectra in parallel to an overwhelming number of matches which is difficult to handle using a web server and HTMLformatted output. It may also appear that implementing such a tool with high computational demands as a web-based service may not be the best choice and client-site applications may be more suitable. On the other hand, this approach requires only a web browser to be accessible for the research community, thereby facilitating access to large amounts of available reference data. Some of the shortcomings could be addressed by utilizing a computer cluster and parallelising the task of scoring or by limiting the allowed file upload size. However, data file sizes will likely increase in the future. Therefore, restricting to file size may not be a viable option. Another option might be to implement a Microsoft Windows binary for a local computer utilization.
The ProMEX library will be extended by the ongoing proteomic analyses. Considering quality assurance reasons, an automated upload facility is not yet intended. However, linking ProMEX to other databases with similar background in plant proteomics research as well as databases such as peptide atlas http://www.peptideatlas.org/ webcite is an ongoing project and greatly appreciated by the authors. Further, other groups are encouraged to submit their data directly to the ProMEX database curators for inclusion. In the future we aim to apply further quality algorithms to improve the library based on spectral replicate analyses.
Interconnecting different molecular levels through databases – a systems biology approach
As described earlier, ProMEX provides also metainformation for every mass spectrum, thereby allowing the user to trace back the experimental origin of the protein appearance. Additionally, the protein identification is linked to transcript and metabolite data via CSB.DB and the Metabolome database (GMD) [1,20]. Gene expression databases such as AtGenExpress can be directly searched with AGI codes of identified proteins looking for correlations with other genes. Metabolite data together with experimental data and reaction pathways are linked automatically via the AGI code of the identified protein. By accessing this interconnected information network data interpretation becomes more convenient. Even more important is that due to the unbiased nature of such large-scale data sets the immediate understanding is complicated. Therefore data storage in a useful way is in our experience indispensable to allow subsequent interpretation in the light of new biochemical knowledge. Thus, the data have to be made available for the community to revalidate, reconfirm or explore new information. These linked databases are probably one of the most important challenges for systems biology in the future.
Conclusion
Here we present the plant proteomics reference database ProMEX. The database consists of tryptic peptide/phosphopeptide fragmentation mass spectra and has the potential to include all different kinds of mass spectra as demonstrated with phosphorylation site mass spectra. Search algorithms are implemented which allow the identification of proteins/peptides based on mass spectral library matching. In case complete LC/MS runs are uploaded as mzData formats it is possible to obtain semiquantitative information in form of the cumulative sum of spectra per peptide and protein. The database allows text searches based on metadata like experimental information of the samples, mass spectrometric instrument parameters or unique protein identifier like AGI codes. ProMEX integrates proteomics data with other levels of molecular organization by linking the peptide-identification to metabolite, pathway, and transcript databases. Based on these capabilities we will exploit the search function of the database in future and extend the approach to metabolite spectra.

Abstract
Background
Students may encounter difficulties when they have to apply clinical skills trained in their pre-clinical studies in clerkships. Early clinical exposure in the pre-clinical phase has been recommended to reduce these transition problems. The aim of this study is to explore differences in students' experiences during the first clerkships between students exclusively trained in a skills laboratory and peers for whom part of their skills training was substituted by early clinical experiences (ECE).
Methods
Thirty pre-clinical students trained clinical skills exclusively in a skills laboratory; 30 peers received part of their skills training in PHC centers. Within half a year after commencing their clerkships all 60 students shared their experiences in focus group discussions (FGDs). Verbatim transcripts of FGDs were analyzed using Atlas-Ti software.
Results
Clerkship students who had participated in ECE in PHC centers felt better prepared to perform their clinical skills during the first clerkships than peers who had only practiced in a skills laboratory. ECE in PHC centers impacted positively in particular on students’ confidence, clinical reasoning, and interpersonal communication.
Conclusion
In the Indonesian setting ECE in PHC centers reduce difficulties commonly encountered by medical students in the first clerkships.

Background
Medical institutions across the world have installed clinical skills laboratories to train students’ clinical skills [1]. Skills laboratory are used to train pre-clinical, clinical, and post graduate students, however in this study we will focus on skills training for pre-clinical students. In skills laboratories, pre-clinical students practice their clinical skills with peers, manikins and simulated patients. Skills laboratories provide a safe environment for practice and learning processes therein can be well structured [2].
However, recent studies have indicated that pre-clinical students entering their clerkships may encounter difficulties when they have to apply clinical skills learned, especially in patient contacts [3-5]. For example, students feel anxious when they have to perform diagnostic or therapeutic procedures with patients because they fear to harm patients [6].
To mitigate transition problems as described above, Dornan et al. [7] recommended inclusion of early clinical experiences (ECE) in the curriculum for pre-clinical students. ECE are supposed to improve preparation of pre-clinical students for their clinical rotations by immersing them in the reality of the clinical environment, by facilitating application of knowledge to clinical practice, and by improving students’ motivation for learning.
In principle ECE can be offered in any clinical setting, including facilities for primary, secondary and tertiary health care. With respect to primary health care (PHC) some studies have shown the relative advantage of PHC centers to provide opportunities for “hands on” practice by pre-clinical students, availability of general practitioners (GPs) to supervise the students, and with respect to the scope of PHC, which next to patient care also includes community health education [8,9]. We have shown the advantages of PHC for practical training of pre-clinical students, compared with secondary and tertiary hospital settings in the Indonesian context [10]. Furthermore, we demonstrated that pre-clinical students who were trained in PHC centers felt better prepared for entering their clerkships. [11]. For this study, the same students involved in the previous one were interviewed for this study after they had entered the clinical phase of their studies.
This study was undertaken to explore the effect of ECE in PHC on students’ performance in their first clinical clerkships. To this aim, we compared experiences of students exclusively trained in a skills laboratory and peers for whom part of their skills training was substituted by ECE in PHC centers.
Materials and Methods
This study was conducted with 60 pre-clinical students who were randomly sampled based on student numbers from a full class of 197 fourth year students of the Faculty of Medicine at Gadjah Mada University (FM-GMU) in Jogjakarta, Indonesia. These students were in the last semester of their pre-clinical studies since the medical curriculum of FM-GMU has a pre-clinical phase of 3.5 years (and a clinical phase of 1.5 years).
All 60 students sampled attended the regular clinical skills training program conducted in the skills laboratory. In duos or trios, 30 of these students were offered in addition an 11-day clinical skills training program in PHC centers (PHC-trained: PT). In the PHC centers PT students were supervised by GP’s who had been trained to become aware of the standard procedures for clinical skills as taught in FM-GMU’s skills laboratory. For their training, GP’s were invited to the skills laboratory to be introduced to the skills training program for pre-clinical students, to attend demonstrations of some skills trainings to instruct them how to train students on certain clinical skills.
In Indonesia, each sub-district has at least one PHC center (called Puskesmas). For example in 2000 in Jogjakarta a sub-district encompassed on average 35,278 people [12]. Each center hosts one or some doctors and paramedics, the latter including nurses, midwives, and pharmacists who may be involved in the teaching of pre-clinical students. The characteristics and the availability of PHC centers in the proximity of any medical school in Indonesia have led us to elect PHC centers to arrange for ECE for pre-clinical students, particularly to prepare these students for their clinical rotations [13]. Eleven PHC centers around Yogyakarta city were involved in this study. Each centre hosted groups of five or six students for 11 days dispersed over a five-week period. PT students were assigned to provide health services, patient management, and health promotion in communities. The other 30 students received for the same time span additional clinical skills training in the skills laboratory, facilitated by senior students trained to act as skills laboratory assistants (not PHC-trained: NPT). Those senior students had received intensive training from staff to assure that training given by them would be equal to that provide by skills laboratory teachers [14,15]. In tha additional program NPT students practiced (“doctor-to-patient”) communication, physical examination, procedural, and clinical reasoning skills in the laboratory with manikins, their peers and simulated patients.
After conclusion of their pre-clinical program students commenced their clinical rotations in the teaching hospital. Six months after commencing their clinical clerkships 30 PT and 30 NPT students were randomly invited to participate in Focus Group Discussions (FGDs). By that time, each student had completed three or four clerkships (out of the total of 14 clinical departments). During those periods, the students have opportunity to interact with real patients in particular clinical departments in the hospital, such as internal medicine, ENT, surgery, etc. Those students were randomly assigned to three focus groups of ten NPT or PT students, respectively.
FGDs were facilitated by the first author and a research assistant. Discussions were structured by the following questions: 1) What is your opinion about pre-clinical training in the skills laboratory as preparation for your clerkships?; 2) What difficulties did you encounter in your first clerkships?; 3) What is your opinion about ECE in PHC centers?; and 4) What is your impression of the performance of students in the other group, compared with the performance of your own group?”. Each focus group convened twice and each session continued until no more new items emerged.
FGDs were audiotaped and transcribed verbatim by a research assistant. Transcripts were analyzed using ‘inductive content analysis’ by three persons: the first author, a senior clinical supervisor from the teaching hospital, and a research assistant. The first author briefed his co-analyzers about the objective of the study and how to perform open coding using Atlas-Ti version 6. Each coder worked independently to analyze the texts and assigned codes in accord with the main categories (i.e., the four questions asked) and tried to distinguish sub-categories therein [16,17]. To finalize the coding process, a meeting was held with the three coders to discuss their results until consensus was reached. A written summary of the outcomes was distributed among all FGD participants for checking its validity and to solicit comments. Two research assistants met with groups of students and sent e-mails to those not attending to solicit their comments on the summary of the outcomes of the FGDs [18]. The design of this study was approved by the ethical committee of FM-GMU.
Results
All 60 students attended at least one of the FGD sessions. Each small group had two FGD sessions; the number of participants in each FGD sessions varied between six to twelve.
In the coding process 1,433 issues were identified in the 12 FGD transcripts. During the meeting of the coders consensus was reached that ten sub-categories could be identified, based on the issues most frequently emerging in each main category. In reporting on the outcomes of the FGDs the focus will be on issues mentioned eight times more frequently in either NPT or PT groups to condense presentation of the data in Table 1. Of course all issues mentioned were recorded and the most striking ones will be presented in the text.
Table 1. Issues referred to eight times more frequently in FGDs with NPT and PT students
In the checking process with FGD participants only minor comments were made with respect to weaknesses of training in the skills laboratory and expectations to practice in PHC centers during the pre-clinical studies. Those comments have been integrated in the final outcome of the FGDs.
Pre-clinical training in skills laboratory
NPT students more often made positive remarks about their preparation for interpersonal communication skills and had more suggestions for improvement of the skills training program than PT students. On the other hand, PT students more frequently recognized differences between standards for skills as taught in skills laboratory and the way those skills were performed in clinical practice. Both NPT and PT students frequently advised to include ECE in the pre-clinical curriculum.
“…the [ECE] program is good, because it improves students’ clinical performance [in early clerkship] … all [pre-clinical] students should have it from the beginning… (NPT/1/1)
Difficulties met in first clerkships
In this main category large differences emerged in the number of difficulties mentioned by NPT students as compared with PT students. NPT students brought up 202 different problems whereas PT students mentioned only 52. Difficulties to perform clinical skills were mentioned 74 times by NPT students versus 14 times by PT students. Difficulties mentioned by NPT students related to communication skills, including difficulties with interpersonal communication (e.g. greeting, showing empathy), taking an anamnesis, and understanding the local dialect. NPT students had also encountered more difficulties than PT students with physical examination (e.g., in ophthalmology and neurology) and recognizing pathological signs in patients (e.g., wheezing sounds, liver enlargement, and cardiac murmurs). Both NPT and PT students frequently mentioned that different guidelines given by distinct clinical supervisors negatively impacted on their performance in physical examination. With therapeutic skills NPT students had suffered most from differences between manikins and patients, e.g. with insertion of intravenous lines, minor surgery, tracheal intubation, urethral catheterization, and assisting at a delivery. More often than PT students NPT students mentioned to be afraid to harm the patient.
“…when we insert an intravenous catheter or perform minor surgery on a manikin, they [the manikins] are not screaming, but pediatric patients are always screaming from the beginning (…) Performing wound suturing on a patient feels really different, [real] skin is much more stretchy…” (NPT/3/1)
Beyond difficulties with the application of clinical skills, NPT more frequently than PT students referred to difficulties in adapting to the clerkship environment, cooperation with other health workers, and with clinical reasoning. NPT students also more often than PT students mentioned low confidence, confusion, and anxiety in front of patients. NPT students shared that they first needed to watch a clinical procedure before performing it themselves.
“…Yes, indeed, because we [PT students] had earlier [clinical] experiences, we are confident and courageous if the supervisors give us opportunities to perform clinical procedures on patients, like inserting an intravenous infusion, venapuncture, minor surgery, delivering a baby, etc. … It is different with our [NPT] colleagues who prefer to observe prior to performing…” (PT/3/1)
Both NPT and PT students frequently stated that insufficient supervision had been a problem in their first clerkships.
Students’ opinions on ECE for pre-clinical students
Based on their personal experiences, PT students commented extensively on their attachment in PHC centers. Based on their observations also students in NPT groups shared opinions on ECE. The main advantages of ECE identified by many PT students was the opportunity to practice clinical skills in a real health care setting. ECE made PT students aware of differences between the skills laboratory and a clinical environment. ECE had positively impacted on PT students’ motivation for learning, on their confidence, clinical reasoning, and interpersonal communication. More than NPT students, PT students were given opportunities by their clerkship supervisors to perform clinical skills.
“…in the ENT department [when students sought permission to perform a clinical skill] the supervisor would always ask: “Did you ever perform this skill [on a patient]?” (…) On the first day [of that clerkship] we [NPT students] observed our [PT] peers [performing that skill] and practiced with them. Then in the second day the supervisor would also allow us [NPT students] to perform that skill…” (NPT/1/2)
Both NPT and PT students recognized that the effectiveness of ECE depends on the quality of supervision in the PHC centers. In particular NPT students were worried that the range of clinical procedures which could be practiced in PHC centers would be too limited.
“…opportunities to observe various clinical procedures are more available in the Sardjito [teaching] Hospital than in Puskesmas [PHC centers]…” (PT/2/1)
In addition, NPT students recognized the advanced functioning of their PT peers in the first clerkships.
“…the way my peer [PT] student Tasya interacted with patients differed strongly from my [NPT student] performance … she looked ready [for practice] and knew what should she do with the patient… and I was not.” (NPT/1/1)
Discussion
This study shows that students who participated in ECE in PHC centers had less difficulties than NPT students with the transition from the pre-clinical phase of their studies to the clerkships. In the setting of Indonesia PHC centers proved to be suitable to offer ECE to medical students.
PT students and NPT students spent the same time on clinical skills training but in different contexts. PT students had the opportunity to interact with real patients in PHC centres. We assume this context to be more challenging for them than for NPT students who expanded their training in the skills laboratory setting. Even though the NPT group cannot be regarded as a true ‘control group’, we feel the advantages of ECE as experienced by the PT students clearly demonstrate the advantage of inclusion of such activities in the pre-clinical medical curriculum.
ECE impacted in particular on students’ confidence, clinical reasoning abilities and interpersonal communication skills. With respect to confidence, PT as well as NPT students (based on experience and observation of peers, respectively) frequently felt ECE had or would boost their confidence. As far as the NPT students are concerned this may be explained by their anxiety and lack of confidence when in their first clerkships they were confronted with patients. Apparently PT students had passed this stage in the PHC centers, where possibly close supervision by GP’s had supported them in overcoming this barrier.
Expectations with respect to improving clinical reasoning through ECE were far more frequently voiced by NPT students than by PT students. Perhaps expectations were set too high in the NPT students who had not participated in ECE, or the NPT students were highly impressed by the progress PT students had made with respect to clinical reasoning during ECE, often demonstrated by their ability to appropriately perform an anamnesis and to arrive at a diagnosis.
Opinions of students with respect to interpersonal communication yielded the most convincing data in support of ECE. NPT students mentioned frequently to feel they had been adequately prepared for interpersonal communication by training in the skills laboratory, but apparently this perception was challenged in practice because PT students expressed this opinion less frequently than their NPT peers. On the other hand, when PT students had entered the clerkships ECE had apparently erased their difficulties with interpersonal communication, whereas understandably those difficulties persisted in NPT students. This explanation is corroborated by the high frequency by which PT students advocated ECE for practicing interpersonal communication skills.
The reduction of difficulties encountered by PT students in their first clerkships as compared to those encountered by their NPT peers resulted in frequent recommendation by students from both groups to include ECE in the pre-clinical curriculum. It is remarkable that NPT students did not mention the advantage of having clinical experiences in the pre-clinical curriculum, although in the first clerkships they had been impressed by the advanced functioning of their PT peers. Perhaps their failure to see this advantage reflects the doubt whether attachments to PHC centers can adequately prepare them to perform advanced clinical procedures.
The data gathered from the students confirm the shortcomings of clinical skills training in the skills laboratory to prepare students for the clinical phase of their studies as also observed by others [2,19,20]. Perhaps offering more sessions with simulated patients and patients manifesting certain pathological conditions (e.g. liver enlargement, heart murmurs), if possible situated in a hospital environment might compensate for some of the shortcomings of skills laboratory training as experienced by NPT students (and thus also by regular students) [21]. Furthermore, involving clinical supervisors in the hospital in trainings with (simulated) patients may assist in further adjustment of clinical procedures as taught in the skills laboratory and as performed in practice. On the other hand, ECE seems more efficient to improve preparation of pre-clinical students for their clinical rotations than considerable expansion of the skills laboratory training program. This may be particularly important in developing countries where budget restrictions call for the selection of the most cost-efficient solutions [11].
Insufficient supervision experienced in the clerkships by both NPT and PT students may have elicited their joint comment that also effectiveness of ECE in PHC relies on the quality of supervision. Also for this pilot experiment FM-GMU skills laboratory staff extensively informed supervisors-to-be in PHC centers about the pre-clinical students’ level of competency and their derived learning needs, and about standards for execution clinical procedures as taught in the skills laboratory [22,23]. Unfortunately in many developing countries (including Indonesia), PHC centers may be severely understaffed [11,24]. Therefore, in the selection of PHC centers for ECE availability of adequate numbers of supervising staff must be carefully considered, because medical students need close supervision particularly in their first encounters with patients [25].
In the Indonesian setting PHC centers proved to be suitable to offer ECE for pre-clinical students. Although more advanced equipment and procedures may not avail in PHC centers, this setting was apparently ‘clinical’ enough to satisfactorily prepare pre-clinical students for functioning in the hospital setting. Training in PHC centers also fits in with the policy of the Indonesian government which requires that every medical graduate must serve for at least half a year in PHC. Furthermore, ECE in PHC centers may motivate some students to opt for a future career in PHC [7].
A limitation of this study is that the assessment of the effectiveness of ECE in PHC centers was only based on student opinions. By involving students representing two different groups (i.e., PT and NPT) and by comparing their mutual opinions we aimed to improve the validity of these subjective data. Furthermore, we have taken the paucity of significant comments by FGD participants on the summary of the FGD sessions as support for the validity of the analyzing process as applied.
In a future study we intend to involve objective assessment tools to compare the clinical performance of NPT and PT students during their first clerkships. A suitable approach in this respect could be assessment by direct observation using the Mini-Clinical Evaluation Exercise (Mini-CEX) [25].
Conclusion
In the setting of a developing country, an 11-day ECE program in PHC centers was demonstrated to significantly reduce difficulties as commonly encountered by pre-clinical students in their first clinical clerkships.

} | cccc_CC-MAIN-2013-20 | THE BEST OF DADA POKEY !!!
Dada Pokey provides grist for the Pokey hilarity mill, but, as with all things dada, does not distinguish between that which is truly funny or weird in human eyes, and that which is merely random. "The Best of Dada Pokey" is in no means a contradiction in terms or an imposition on the random nature of Dada Pokey; rather it is a celebration of the human spirit. Or something. You know, there are probably classes I could take where I would get credit for this.
HERE IT IS, WENCH!

Note: This post was originally written on August 16, 2012 in response to the announcement of Rockman Xover. It was updated on October 13 with a slightly more general tone to reflect new developments since then. It is still focused on Mega Man as I still feel it best epitomizes everything wrong with Capcom today.
When I read the post on Destructoid about a new game called Rockman Xover, I got a pretty good laugh. I laughed because I totally saw it coming and a lot of people are upset that the all-important silver anniversary of Mega Man is going to be celebrated with what looks to be a trashy cell phone game. I'm usually not one to judge on early appearances, but there's precedent for this one not looking like it's going to be a barn burner, and even the venerable Tony Ponce agrees. I've gone on record multiple times playing devil's advocate for issues like this. This time, I see a solution. Hear me out, because it's not going to be easy.
A lot of commenters on that post and the original source they cited are understandably farty over this announcement, claiming that Mega Man Legends 3 and Mega Man Universe were canned to make room for this and the infamous Mega Man X port on iOS, among other travesties, like they always do when a Mega Man thing is announced that isn't a new game. I think they're wrong, because Capcom made the right call pulling the plug on those projects when their hearts weren't in it. They know that a whole new game is too much for them to handle, so they don't do it. I'd rather have nothing at all if the developers would not have been proud of the result had they continued. For that reason, I tend to side with the developer when a game gets cancelled and I still do in these cases. I know what it's like to abort a project I invested a lot of time and effort into and how much it sucks, so I sympathize with the developer any time they announce a big cancellation. (Update: It's been suggested to me that their hearts actually were in it and it was cancelled because the executives wanted it dead, not the actual coders. If that's true, it doesn't change the points I'm about to make.)
It makes me churn a little when I see people not caring about the quality of a cancelled game because they just want to play it. They're the ones who enable Capcom to make sequels that do not need to be. But I'm getting off point. This isn't about sequels, it's about what led to this pitiful milestone release. This has been a long time coming, because for all the wrongdoing Capcom has been pulling the last few years, they got off relatively scot-free, if not a little worse for wear in reviews. Now that the big name developers and directors have bailed, maybe this is all they're capable of doing with Mega Man anymore. Predictably, early impressions for Rockman Xover are not looking good. Despite this, for the last few years, Capcom has gotten the idea that they can act with impunity because
1. The people who are boycotting or otherwise taking a stand against them aren't doing it right
2. There aren't enough people doing so
3. Sales figures are still counterbalancing any boycotting efforts
This is what happens when people don't properly punish a company that acts out of line. To this day, Capcom is getting money it should not be getting. Now everyone pays the price. By not completely starving Capcom of all profit, they are doing whatever they please and you all swallow it up (or so it seems to them anyway). When I say "you", I mean the gaming community as a whole, because the minority that knows what's what is being drowned out by the people who only talk in dollar signs. For all the people who complain, a few months later, Capcom announces some kind of remake or sequel of a series everyone used to like just to appease to the people calling them out. A shadow of their lofty greatness as opposed to the genuine article will restore their image, just like they did with Jojo's Bizarre Adventure and Darkstalkers and Marvel vs. Capcom recently, and no one learns a thing. Capcom will profit with this title (because Mega Man is still a big name franchise and "social RPGs" almost always make money) and the change that desperately needs to happen never will, because gamers are too short-sighted and selfish to effect any real change in the industry. If you don't like this, then buckle up because I'm going to tell you how to cause that change. And you have a lot of work to do.
I've observed something during this console generation which applies to every major gaming company that missteps more than a few times. No matter what happens, Capcom has enough diehard fans and casual fans who don't know any better to survive the worst beatings that those in the know have to offer. I recall the Wii version of Okami as a particular sticking point with the community at the time over failure to properly credit those involved in that port and even those who worked on the original game. Gamers took offense and a number of them vowed to boycott Capcom for their flagrant disrespect for the hard work of the individuals who worked on this game, but in the end, nothing happened. Okami on the Wii sold well enough and everyone forgot about it by the time the sequels came out. (Funny how Capcom's scramble to fix the infamous cover watermark was viewed as a token of respect before word of this got out.)
Earlier this year, there was a case regarding Dragon's Dogma where a junior developer was nearly driven to suicide, and people still bought the game even after the story broke. Whatever horrid working conditions caused that case live on because there's no incentive to change it -- that is, poor sales as a result of people boycotting Capcom out of principle, just like they didn't with Okami. Granted, this has more to do with Japanese business culture than Capcom and is on the same level as the people who refuse to shop at Walmart. I bet it happens all the time and this is a case that managed to make headlines. But since Capcom was outed for it, why not make an example of them?
After those missed opportunities to make a change, the failing I'm seeing is that gamers are saying Capcom should pay, but no one is doing anything to make them. People tell me that Capcom learned their lesson with Ultimate Marvel vs. Capcom 3 and Street Fighter X Tekken in regard to mishandling gamers' trust with their money (free 2013 update to the latter notwithstanding), and they also tell me I'm silly for thinking Capcom needs even more punishment. Yeah, Capcom has learned its lesson, which is why they're still going at it with these half-hearted cash grabs and suboptimal working conditions. Isn't that right, Yoshinori Ono? How is anyone going to learn anything with that kind of attitude?
Actions speak louder than words, and for years I've been seeing a whole lot of words and barely any action. Forgive the hypocrisy on my part, but I can't do it alone. You can't do it. One person cannot do it. Nor can a hundred. Nor can a thousand. Nor can a hundred thousand, no matter how strong they all think they are as a group. VGChartz shows that Capcom-published games routinely push millions of copies, even the "bad" ones like Resident Evil 6 that still broke the one million barrier. That's how many people we need to do it. Capcom is big, and we need to be bigger. Gamers need to all stand up at once and give them the biggest middle finger a Japanese gaming company has ever seen for any change to happen, because we've been taking it in the rear for far too long.
Unfortunately, with the way the industry is set up now, no one can communicate to the most important game companies and tell them off directly, never mind foreign companies. Community websites and Facebook pages are only for advertising, not for feedback. Yeah, bad feedback on social media has pressed Capcom to say they are reconsidering how they'll handle DLC in the future, but that's just more words.
(Update about Resident Evil 6: I don't want to have to bring up the fact that it has on-disc DLC because development on it started long before Capcom made the claim that they'll rethink that policy. I don't care that the DLC is free; this should never have happened in the first place. That said, it was going to happen eventually, like all potential ways to abuse monetization schemes, so it just sucks that it had to be a company with such a fine pedigree as Capcom.)
Speaking of words, petitions mean squat. They imply support for a cause other than the surgical extraction of everything wrong with a company, which in Capcom's case is probably no longer feasible. Let me digress here for a moment: Suppose a petition does work. We get one game, maybe a handful, the signers wanted. Then what? Does the company change in any meaningful way as a result of listening to the fans? Are more games in their vein promised immediately regardless of sales and the company's current direction just because the fans made their voices known when they should not have needed to in the first place? Or do the fans wait and write up another petition for the next game they decide is worth more than the company decides it's worth? Given how long the petition process takes, I just don't think it's worth the effort and I'd rather see that effort bettering the industry rather than racing toward short-term gains.
That tangent aside, we need unprecedented backlash to make Capcom turn over a new leaf, because like everyone else, I desperately want this bad Capcom to go away forever and a good Capcom, or even the old Capcom that did cool things in the last console generation and before, to appear in its place. But Exy, you're being too hard on them! Why kill the whole company off? Capcom still does good stuff once in a while. I know. Capcom was very good just a few years ago. I know this because of the lengths they went to to spread Tatsunoko vs. Capcom: Ultimate All-Stars around the planet. No one saw it coming, and Capcom did everything they could to make it work, and it totally did. They fixed the original up and even threw in new characters just because. They listened, even though it wasn't the most anticipated game of its season, and now few people play it anymore. (I believe it's due to poor timing, but I'm told that it was because it was on the one console most of the target audience didn't have, but that's for another article.) I can't emphasize enough just how much of a miracle Ultimate All-Stars is, and I feel it's been wasted. Who knows how long it'll be before we see such a defiance of region boundaries again?
Then something happened and Capcom got greedy. I don't know what that something was or how long it took, but here we are. Whatever trace of good is left in the current Capcom is being overshadowed far too heavily by the bad. The way the industry is set up, we can't help them differentiate. If we buy only what we want and not what we don't want, we will get more of the good. "Voting with your wallet," as gamers like to say, regardless of how fundamentally broken that concept is. (Gotta write that rant sometime.) Unfortunately, too many people buy everything regardless if it's good or bad. Since the undiscerning gamers who make up a majority of the paying customer base aren't being reached, this ideal has no chance of success. The people who don't know any better are voting with their wallets as well, and their votes outnumber yours. I don't care about what the reports say about games held up by DLC and/or gems, games farmed out to subpar contractors, and ill-advised cell phone remakes not selling well. That they're being developed at all means something is wrong higher up. Kenji Inafune and Shinji Mikami and now Seth Killian all jumped ship just before and even during this all went down, and people still held hope. That's all gone now.
Speaking of regions, I need to go back to something that's very personal to me: Voting with your wallet. Sure, it works fine for the usual domestic competitions of highly-rated games versus not-so-highly rated mediocrity, but how do you vote for a game that's not even in the ballot? But first, how do democracies work? Correct me if I'm wrong, but a big part of it is being able to vote out the people who run a state badly and then vote in good people, yes? When was the last time that happened with a game company? Who's going to tell the CEOs who keep companies from being supportive of their customers to go away just because a few hundred thousand people on the internet think they're Jerky McJerkfaces? Does anyone even know what the names of those Capcom executives are? Are they as bad as Bobby Kotick or even worse? Let's ignore the fact that we non-Japanese gamers shouldn't even have any votes in a Japanese ballot, so to speak, or even the fact that I have yet to suggest giving this article to the Japanese since they matter more to Japanese companies like I usually do. The only thing that ousts bad executives is major scandal, and below-average sales is not an example of it. Super bad sales, sure, but there needs to be a string of those, or something really, really bad. I'm talking Virtual Boy bad. You're not going to be able to just vote the problematic executives out, the people who actually make development decisions--not with your wallet, not with Facebook petitions, and certainly not with your internet posts. If there is actually a way to vote executives out, by all means go do it right now. But get all the shareholders to vote with you while you're at it.
I'm assuming the reader of this article is not a Capcom shareholder, so to go back to my previous point, the next best thing is to coordinate a number of people comparable to Capcom's VGChartz numbers to make a difference. The best example I can think of that many gamers working together to remove a problematic individual from gaming is Jack Thompson, and he's never even worked for a gaming company! Countless people contributed to his demise, exposing his misinformed attitudes on gaming, wearing away at his reputation and possibly his mental state, and culminating in disbarment. Why can't we use that synergy to fix a gaming company? Probably because unlike Jack Thompson, gaming companies can distract gamers from their cause with a game. It works every single time, as the biggest American game companies can attest. But that's a whole different battle.
There's hope, however, assuming the problems with Capcom are really all about the money as opposed to any respect for the Mega Man name. A comment on the Destructoid post from Tubatic gave me an idea:
"I propose a year long Game Jam in which people make tons of Mega Man sidescrollers. It's the only way to revive and reclaim it, I think. Capcom just isn't going there."
To which I replied, why not go all the way? Not only do we stand up all together and tell Capcom off, we should blatantly tread all over their copyright and sell such games en masse to send the message that people are willing to pay for them, even if they don't come from Capcom. Capcom doesn't get to see a cent of that money for something that belongs to them. (They don't care about it, right? Is that what you're trying to say, Exy?) Gamers think they vote with their wallets, so I further propose that those people who are still deluded into thinking that gaming is a democracy vote for write-in candidates. Disgruntled fans with talent and a drive to see this franchise retake its place in the top game series of all time should steal the franchise and hold it for ransom. Then we'll see just how much Capcom cares about Mega Man. The fans would essentially be detaining Mega Man against his will, but better for fans to do that than Capcom.
This will only work if:
1. A lot of developers participate in selling Mega Man "tributes" for profit
2. None of those developers give any proceeds to Capcom for any reason, be it respect, hope for a new good game, or anything else
3. A balance between such projects made out of spite to Capcom and out of tough love to them is made
4. At least one of them sells big and the developer openly brags about all the money he's making from a Mega Man fan product
That last point is the most important. A handful of the best Mega Man fan works needs to make bank and have everyone know it. After seeing Rockman 4 Minus Infinity, I have faith in the indie and hacker communities to make games good enough for this to work. As an even more compelling proof of concept, fans decided to make a playable mock-up of Rockman Xover in Flash based on currently available media and assets just to spite Capcom. This is exactly what I envisioned: People taking the fight straight to Capcom and not to the online forums where anything of consequence rarely occurs.
It's like what the old Japanese proverb says--and I'm paraphrasing here so correct me if I'm off--if a whole lot of people all illegally cross the street, none of them can get in trouble because there's too many of them. The same mindset needs to be applied to this Game Jam idea to have any effect. It will end in either a lot of lawsuits, a lot of buyouts, or desperation on Capcom's part, but if it's construed as a mass rebellion, it's my best idea to get Capcom to panic and rethink their strategy. Some people suggest that Capcom should sell the rights to Mega Man to a company that cares more about it. If they take Mega Man games to the heights seen in the best ROM hacks and fan games, then I would be for it. But the problem of Capcom being Capcom would still exist. It would be a half-fix: Mega Man gets a chance at redemption, while Capcom just has one less franchise to work with. I would rather all of it be fixed at once.
Mega Man needs to be taken by force if it's to get any better. Of course, this is a horrible idea--mostly because Capcom always has their other departments to make up the slack, not just because it's stupidly illegal--but Capcom is clearly hurting for cash whether they actually need it or not, so let's hit them where it counts. The title of this post is about fixing Capcom, but I really think we need to tear them down. There are just too many issues with this Capcom to expect a few fixes to make everything right. If this Capcom falls, the shock will be felt throughout the entire industry, like when Sega stopped making consoles. Again, Capcom is big, but we are bigger.
The best legal way to do this, of course, is to boycott. Let me tell you how. Three steps.
A lot of customers have claimed over the years on news posts that they are through with Capcom for some mistake they made. To me, this means cutting off all financial support completely. It's simple, really. If they get any money, they win. They interpret that statement as meaning that their current strategy is profitable, so there's no incentive to change. What you need to do is say no. No more appeasements. No more second chances. No buying anything of theirs on Virtual Console or whatever. No buying incremental upgrades for fighting games just to stay competitive. Nothing. This step is the easiest, but it is by no means easy or even the most important, as I'll explain below.
The next step is the most overlooked: Don't just stop buying anything Mega Man or anything Capcom, make sure everyone else stops too. Urge random civilians everywhere, in game shops, online, at gaming meetups, not to support Capcom. Educate them. Maybe we'll get a fraction of the millions of people needed to change Capcom this way. It's our best chance. I would predict a great many of them won't listen or won't help, but if you really want Capcom to change, you won't let that slow you down. This is what I took issue with most with Operation Rainfall. Their primary goal wasn't about convincing the gaming community at large that there needs to be significant change to the localization process, but rather about getting three games that appeal to JRPG and Wii owners. Now that they have them, they're resting on their laurels. And now people are questioning if the effort was worth it. Like I said in my spiel about petitions above, they should be focusing their efforts on fixing the industry, ideally from the inside out, not begging to it. Don't make their mistake -- Remember, this isn't about Mega Man, it's about the industry. Get everyone you can to join your cause. There is a lot more at stake here than a bunch of cancelled games and a hideous iOS "anniversary celebration." Why should we still have to expect mediocrity at this point? How can any of you get excited for Ace Attorney 5 when we're missing an entire game of investigating? Maybe it wasn't that great, but on principle we still should have seen a glimpse of it anyway.
Now here's the hardest--and most important--part: Stand strong and don't buy anything from Capcom, no matter how good the games are. It sounds like I'm repeating myself at this point, but this is where a great majority of boycotts fail: The boycotters let themselves be won over by announcements of new games. A lot of would-be boycotters don't seem to understand that getting excited for a new release is the opposite of a boycott. Still others hold the "Damn you Capcom, I want to boycott you so stop releasing games I'm going to buy" mentality. Even if tongue-in-cheek, that mentality is pushing us two steps back for every step forward. Then the whole process starts anew. Enough is enough. Say you're going to boycott Capcom, then stick to your guns. Resist the temptation to give them a dime. Give that money to talented fans instead, just as long as that money doesn't end up in Capcom's bank account. This isn't a vote, it's a protest.
When a boycott is done right, it hurts the executives and the other people poisoning the company from within, but it also hurts the programmers, it hurts the artists, it hurts the musicians, and most of all, it hurts you. It's sad and unfair to the hard-working employees and maybe even to you, the Capcom fan or ex-fan, but it's the only way -- after all, this is what boycotts do. There's going to be a lot of collateral damage, but it's that or allow Capcom to destroy themselves. This Capcom needs to know the suffering everyone involved had to put up with for years. Think about what they've gotten away with, all the people they hurt, all the disappointments and the times they cheated you, because they are not. No matter how painful it is for you, hurt them hard. Show no mercy, for they have none. If they announce a new game, hurt them by not caring. When the new game is released, hurt them by stifling week one sales. When DLC is announced, hurt them by not buying it. Every time this happens, hurt them again and again. Once they're on their knees begging for another chance, hurt them more. Hurt them because you love them. If you really care about Mega Man, then hurt Capcom for all the times they hurt Mega Man. If you love Street Fighter or Resident Evil or Devil May Cry or what have you, hurt them for what they did to those series. Hurt them for every old Capcom series you love that has not been given a chance this generation. If you care about Capcom, hurt them for all the times they hurt their customers and their employees. Hurt them nonstop until their bad influences are completely driven out, and then we can rebuild with whatever's left. Hopefully, the affected programmers and artists and musicians will take Kenji Inafune and Shinji Mikami's lead and find better companies that are more than willing to take them in, and then they can hurt Capcom as well. For all I know, maybe that's what a lot of them want. If you're a Capcom employee or ex-employee and you're reading this, I'm sorry if it made you feel bad. Most likely, this isn't your fault. But I'm not one for third chances.
If it sounds like I'm saying Capcom is beyond hope, notice how I've been using the term "this Capcom" throughout this post. I believe this Capcom has been corrupted from the one I grew up with, the old one I mentioned earlier. I don't like this Capcom and it pains me to see Capcom fans supporting them. This Capcom is not Capcom. This Capcom is the enemy. This Capcom did not give the world Mega Man X, Street Fighter IV, Resident Evil 4, or Mega Man Legends. Instead, this Capcom gave us Mega Man X on iOS, Street Fighter X Tekken, Resident Evil: The Mercenaries 3D, and now Rockman Xover. This Capcom would never have given us Ultimate All-Stars. The only thing that will stop it is a mercy killing, not just a mild prolonged sting.
If Capcom dies tomorrow, then we can start talking recovery tomorrow. Clearly, no one at Capcom is listening now. If alarmingly low sales is what they need to reconsider anything they're doing, then so be it. Something is seriously wrong with Capcom and it's not going away without a fight. We can only claim victory once the people who made Capcom what it is now leave Capcom forever, or ideally, retire from the game industry forever. Once they're gone, only then will Capcom be able to find new direction, pick up the pieces, and win any fans back for good. It will be a slow, grueling process, but it can happen. It can happen when everyone in the world wants it to happen. I want it to happen. Let's make it happen. And if you don't want to shoulder that responsibility, don't interfere with the people who want this Capcom to perish.

But of course, none of this is going to work. I'm just as ineffectual at getting millions of people around the world to listen as the best games writers are, and that's to say nothing of speaking to Japanese gamers, even if some of them do agree already that this game is the beginning of the end. And for that, I am truly sorry. I'm sorry for wasting your time with bitter rambling and dangerous ideas. I'm just as naive as everyone else involved. I've asked too many questions and the few answers I gave are not very encouraging, but I felt they had to be said. I don't know if any of this has a chance of reaching out to the people who can fix Capcom or can get enough people to get the process started. All I know is this: Capcom used to be good. Now they are not. I refuse to accept that this Capcom is Capcom. They are an evil that must be slain by any means necessary. Boycotting is so hip these days, but no one knows how to do it anymore. Until they learn, everything is for naught.
All things considered, this is probably not the last straw for the fraction of the fanbase that can make this plan go, which is truly tragic since this means that this sad story will only continue. But once you've decided that enough is enough, this article will be here for you. I've said it too many times already, but things will get worse before they get better, and they need to. If you don't think so, if you want to show me that not everyone has to suffer to make things right, if you want to be the change, then prove me wrong. I beg you. But at the end of the day, the real question is this: What is it going to take for gamers to snap and take an actual stand? How much lower can Capcom go? What will Capcom at its most pathetic look like? Are they really getting close to hitting rock bottom? I don't want to think about the answers to these questions. I want them solved before we ever get there. But then again, I am naive.
Note 1: For the record, I just want to say that I'm not the sort who cares very much for milestones and anniversaries. They're great when a game released on an anniversary happens to be very good because we humans like assigning sentimental importance to nice, round numbers, but the pressure to not miss anniversaries for frankly unimportant things is like a big arbitrary deadline. I bet Nintendo did nothing for Metroid's big one this year because they didn't have anything good to offer in time. Better that than, say, Other M part 2.
Note 2: I don't want to suggest that you bomb Amazon and Metacritic reviews with unfairly low scores for legitimately good games because I think that's extremely petty and unproductive, but if that actually hurts them, don't let me stop you.
The past few months have seen a PR fiasco unlike any other. A throng of fans banding under the name Operation Rainfall have decided that they want a select three games because Nintendo has not delivered on their word to bring it over sooner. Their efforts have brought out the absolute worst in irrational fans with a scant few trying to keep them in check. Despite that, it's never going to work. I've been sitting on this post for some time since I heard about Operation Rainfall, but now that Nintendo of Europe is lording it over us poor, poor American gamers, it's a perfect time to get it off my chest. While the majority sees this as a group of concerned gamers trying to reach out to a company, I see it as a subset of Western gamers waging war on a subset of Eastern gamers. And frankly, it won't end well for either side.
The illusion of democracy
This movement and others like it operate under the assumption that the relationship between gamers and companies is democratic. In an ideal world, that would indeed be how the business worked. Gamers speak, game makers listen. That's how it's supposed to go. Instead, neither is happening: Gamers are screaming and game makers are turning a deaf ear. As you will see on any of Nintendo's social network profiles, the vast majority of gamers affected by this don't see a business opportunity, but rather an enemy. Nintendo is the devil for not giving them what they ask for. Not allowing them to give them their money, as a lot of them like to put it. There has been a breakdown in communication and the only way to solve it is to write letters and compare them to Justin Bieber.
There are, unfortunately for them, two fallacies with this thinking. The first is that the hardcore fans that comprise these movements don't realize is they are not the majority they think they are. Nintendo's fanbase is composed largely of the dreaded casuals who aren't aware of the pressing issues that sites like this report on so heavily. With Nintendo, much of their customer base is unaware of the problems plaguing their hardware and software. (I have plenty of grievances against them myself, but that's for another post.) The hardest part for them to accept is that even though they're the most aware of what makes the gaming industry work, they are the minority of the total number of gamers. To put it in perspective, Operation Rainfall has 2860 followers on Twitter and 8522 people on their Facebook page as of this writing. Nintendo of America has 133730 followers and 296621 on their Facebook page. If Operation Rainfall is to be taken seriously by the people who matter, they need to expand and fast. They need to compete directly against Nintendo for the market share that the latter adores so much. They need to convince the casuals that outnumber them. If the true majority speaks out, I guarantee you that Nintendo will actually listen. A PSA isn't going to cut it. Some nobody with a webcam and the gall to wave cash in front of it isn't going to change any minds at Nintendo. Despite what anyone says, Nintendo's number one demographic is still younger gamers and their parents. The only thing they know about boycotts is that a bunch of dudes dumped crates of tea into the river and became a nation. This is no way to get anything done in this industry.
In the case of decidedly hardcore companies like Activision and Ubisoft, petitions against things like bad DRM work because it actually is a majority of their customers making those outrages. Companies like Capcom, Valve, and Atlus, which are famed for their attention toward their respective fanbases, are in fact comprised almost exclusively of the hardcores that populate sites like this. (In Capcom's case, it's arguable, but that's for another post.) They're fully aware of any backlash and do whatever they can to fix it whenever they're in the mood to. And yet, they don't always do what we ask them for one reason or another. Worse yet, they are the exception, not the rule. They only exist for hardcores, who, as I've said before, are the minority in this climate of phone games and casual throwaway titles. Make no mistake, I have nothing against petitions for bad business decisions like abusive DRM. In this case, this is a decision that has a lot more to do with freedom. It has to do with demographics, which leads me to my next point.
Excel-2011 goes political
The second problem is that these fans are the most selfish, ungrateful, myopic, inconsiderate gamers on the planet. I see right through the purpose of these supposed grassroots movements. They don't care about Nintendo's future or allowing them to take their money. They just want three games they think they deserve just because they're loyal customers. You would think such loyal fans would do anything to meet their favorite company halfway. Sadly, all they can think to do when there's a misunderstanding is shout and spit and cry. While Operation Rainfall puts up an air of pretentiousness to distance themselves from the babies, the people that make up the rest of the operation do not hesitate to threaten to violate Nintendo's intellectual property rights if their demands aren't met. What you probably don't know is that the organizers behind the operation are no better than their constituents. They're just as selfish, except they let others revel in their delusions. Their stated goal is to convince Nintendo of America to bring notable titles to the worldwide markets. Who is anyone to decide what titles are "notable"? They see something that looks cool to them and sit around waiting for the big announcement that they can play too. When it doesn't come, rather than accept that Nintendo decided it wasn't a risk worth taking, they declare war. This isn't the first time it's happened, and yet Operation Rainfall has thousands of supporters even from people who don't need it. They have successfully manipulated thousands of people into putting aside their rationality. They won't stop until the entire world knows that they are starting a revolution.
What all of these fan movements fail to do is consider the other side of the equation, what their enemy thinks about them. Running a business is a very difficult thing. Running an international business is even harder. Do you honestly believe Nintendo of America would announce that they would publish some Japanese games and then turn back on their word after seeing the support for it? Do you really think they're trying to spite you? There could very well be some bigger force at work that's conspiring against them to not release it right away that doesn't exist in Europe. It could be plain old incompetence or it could be some legitimate issue that they can't disclose. Even after acknowledging the outcry and turning the other cheek on Facebook and their mailboxes, Nintendo will not hear the end of it. They're the real victim here, not the gamers who feel betrayed. Here's the key: Nintendo did not betray you. They did not ever "join" you in the first place. No matter how hardcore you are, you're just another customer who can't give more than $50 at a time for a single title. Which is worth more? A dollar from a hardcore supporting Operation Rainfail, or a dollar from a casual gamer who has never played an RPG in his life? Whether they think badly of Nintendo or not, a dollar is a dollar. That's all that matters.
Gamers want nothing more than to be heard by the game companies. They want to be pampered and given what they want, when they want it. Social media has so far not gotten us anywhere close to that ideal. If the game industry is to ideally be a democracy, we are heading the wrong way fast. Petitions should not be the norm as Operation Moonfall is looking to be. In a real democracy, interest groups are often ignored or ridiculed if their motives aren't in line with common sentiments. Here, they get unanimous support if they aren't 100% insane. We have "operations" that fashion themselves after subversive groups looking to effect change from the ground up by any means necessary. This isn't a compliment; that they think this is the only way to get things done is a very sad thing. I am frankly afraid that Operation Rainfall has gotten as far as it has. Should it succeed, it will set a very bad precedent. It will show that the minority of hardcore gamers get what they want, regardless of whether it is in the best interest of the companies they fight so hard. More importantly, it will show that being irrational and naive to the larger workings of an international corporation really is the way to get products. They think that just offering money is the solution. They honestly believe it's that simple. Sadly, it costs money to earn money. Nintendo of America has decided that it's not worth the financial risk that localizing these relatively unknown games requires. They have determined that their customer base neither needs nor wants this game, simply because the part of it that matters hasn't made a stance on it. It's fortunate that Nintendo of Europe didn't think so, but I'll get to that later. Nintendo of America claims it will track sales of Monado in Europe, but when was the last time that correlated to potential American sales?
Something to think about
I've talked a lot about the Western demographic, so here's a question about the other side to mix it up: When was the last time a group of Japanese gamers clamored for the release of a Western game in Japan? How is it that Japanese gamers are content with what they have and we Westerners bicker amongst ourselves over whether we deserve any of what they have? Is it really right for Japanese companies to listen to their customers who are right there next to them and mistreat the Americans just because their American branch isn't doing their job?
An aside: Region locking
A lot of people hate region locking, and with good reason, not least of which is that the successors of systems that did not feature it now enforce it with an iron fist. The real reason for its continued existence evades many gamers who, as I've said, are selfish. They don't consider the economic or political justifications for region locking, notwithstanding the taking away of freedom from one generation to the next. They just see it as another weapon pointed at them to keep them from enjoying something that wasn't made for them. Sure, those reasons may not be good ones. DRM is a complicated affair under the hood, whereas region locks are a single line of code (so to speak) in software that can be set on and off at the publisher's whim, as proven by the handful of region-free releases on the Xbox 360 and the region-unlocking solutions effected by hackers. If that's the case, why keep them? Why not just erase them and let the money flow in from all over the world? Why keep fighting the hackers who will eventually get their way in order to get less money? Heck, why not go all out and make every single game be released internationally at the same time?
Off the top of my head, I can think of two reasons. You've probably heard them before and think they're a load of crap, but I feel the need to bring them up as they are relevant to my next points. I don't claim to know a thing about economics, but I would think that keeping domestic income in its own region rather than allowing it to cross borders and be subject to conversion fees is better for all involved, not least of which is a regional branch of a Japanese company. The second is that keeping regional releases in markets made for them ensures that nobody is accidentally sold the wrong regional version of a game. It can happen, especially on the internet. Differences in culture and social mores are far too vast to risk violating by releasing games internationally without any consideration. You may not mind or even actually know the original language, but, as mentioned, you're the minority. Nintendo is not willing to take that risk on you. Region locking is one step toward ensuring that people in a given region don't see what they don't need to see. It may not be the best solution, but no one has proposed an alternative. I would like to point out that I hate region locking as much as anyone, but I can at least respect why they're there.
On the issue of importing, there are those who also pledge that they will buy an import version of the games. Unfortunately for them, this is equally futile, as import markups benefit only import dealers. It may help your conscious, but when has moral fiber ever made any money? The money also goes to foreign developers, and even then it's a fraction of what you paid; not a cent goes to the people who actually need to see that money. They're willing to accept a foreign product rather than canvass for support for something that they don't have to jump through hoops to get. Should we be willing to subject ourselves to breaking the law just to play a video game? Yes, the import numbers can be a powerful figure, especially when a company decides to take a risk by making their game region-free. But Western stores generally don't market region-free games from overseas despite it being playable on Western systems. So the customers who want them still have to go through the extra trouble of paying extra for a game they will have no trouble playing just because it's not made for their market. Why do you suppose this is? Why, in an age where everyone is aware of every culture in the world, do game companies still have to worry about regions? Do you think game companies like how they have to go through the trouble of making multiple versions of the same game for different languages even when it may not be necessary? Why does Nintendo and Microsoft have to put up with anti-region locking sentiment? (Sony region-locks too, but they do it in a way that happens to keep them out of this debate.) Do you really think they're the ones you should be fighting about this? I believe there is a much bigger force that is conspiring to keep region locking in place, but no one can see them. No one wants to look at the big picture, so they continue to attack the people doing the region-locking instead of the people making them do the region-locking. I can go on, but this is a post for people being immature about three specific games, not a general practice.
How to get your way
As far as money goes, in order to effect any real change, we have to communicate to the decision makers. As you might have guessed, they only speak in terms of income, not social media trends or fan voices because history has shown that they don't always correlate to income. Your first instinct is to "vote with your wallet." Therefore, there are three ways to "vote": Buy, don't buy, or pirate. Two of these options gets you what you want. Two of them leave the company worse off. One of them does neither. It's impossible to count sales that were not made. The only numbers that can be calculated are legitimate copies and illegitimate copies. In a real democracy, constituents can pick and choose which issues they want to voice their opinions on. In a commercial industry, you're either all for or all against a company. That is the real problem with these movements. Not buying is the obvious choice, but there aren't enough people for that option to make an appreciable mark on sales records. It's a self-defeating strategy.
But let's assume that's not the case. The only way to speak out to Nintendo is to, as some members of this site put it, "not reward bad behavior." Fully cutting off your support to Nintendo, financially or otherwise, is the only real way to speak to the people holding the money, and therefore power, in the company. You have to show them that if you don't get what you want, you will give your money to someone else who will. It's been said before, but this is how real boycotts work. If you still support them by buying other Nintendo-published products, you accomplish absolutely nothing. Flinging complaints, slurs, and slander over their social media gates also does nothing for you, since bad PR hasn't stopped Nintendo from making any decisions in the past. They've made good and bad decisions in the past, and a large majority of them had nothing to do with what you had to say, only what you wanted to pay for.
This is enough for the more sensible people, but I want to challenge them to go one further. Speak out to the people who really matter. Take it to the Japanese branches. Learn Japanese and play the games the way they were meant to be played. With some exceptions, Japanese gamers matter more to Japanese companies than gamers from other regions. They turn to them first for input on their design decisions and wonder later why the prospective American customers hate the changes. They're generally better about it now, but there is still a massive barrier that no one is willing to overcome. Those who do are still only the exception. They aren't setting an example. There aren't more than a handful of Cave Co., Ltd.s in the world in 2011. I'm going to leave it to you to figure out why.
A hint that's lost on you
As a technically concerned gamer, I have one other solution for the guys who think petitioning an old-fashioned company is going to work, and it's one that goes back at least a decade. Mother 3 is a game that, despite much demand from overseas, has never been considered for release even by Nintendo of Europe. As ruthless as the Mother fan community can be, they knew that after years of crying about it, that wouldn't get their holy grail to them any sooner. What did they do? They took it into their own hands. They made a frankly marvelous translation patch and released it into the wild for all to enjoy, and they did it without shedding a single drop of blood.
Fatal Frame IV is the same story. It was supposed to be released in Europe, but a fallout between Nintendo and Tecmo had those plans fall through. Did the Fatal Frame community start a minor firestorm over that? God, no. They made a translation patch of their own and went out of their way to ensure it would only work with legal copies and any kind of Wii, modified or not. Countless other games that fans in America and Europe think they want were translated by other fans who were willing to cross legal boundaries to bring back a treasure.
This is, in my opinion, the right way to get what you want. Nintendo failed two sizable communities but didn't get any harsh PR for it. Those communities knew that Nintendo doesn't care about them or their money, so they didn't care for what they thought either. They supported themselves and even made sure that money went to Nintendo anyway for trying. I personally think that last part doesn't help matters any, but at least they aren't greedy about their work. Heck, even Pokémon Black and White got translation patches for the Japanese ROMs well before the English versions were released, and they didn't even have to. It's illegal, but they didn't want to wait, so they didn't.
So where are the translation patches for Xenoblade Chronicles, Pandora's Tower, and The Last Story? Why did no one even attempt to beat Nintendo to the punch for their sake? Why did the community resort to throwing tantrums? Why is Operation Rainfall not taking a stronger anti-piracy stance when so many of its supporters are pledging to do exactly that? Because the periphery for Mistwalker's fanbase is selfish. They don't want to find a champion that will get them what they want despite Nintendo. They think that only official action will do it. They don't want to show Nintendo that it could be done. They expect that saying they'll buy an English version will do it rather than show them that they will support an actual thing. They aren't giving their support to an alternative group of workers. They are supporting only a group of dreamers. Granted, as a technically concerned gamer, I am confident that someone will come up with a region unlocker homebrew that will run European copies of Monado in a similar fashion to Fatal Frame IV within hours of its release, but again, it won't help Nintendo of America one bit. It certainly won't help Operation Rainfall, who have stated that not only do they hate homebrew, their goal is an NTSC release, not a PAL release. They cannot be happy that Europe is getting something we still don't have just because they don't have it too.
Why Operation Rainfall must not succeed
The only way to speak to the decision makers is to realize that business is all or nothing. Failing that, invent an alternative and support that. I would personally have you learn Japanese and never worry about a company deciding to bring a game or three you want in a package that's convenient for you. But all of that is too much work for you, isn't it? You can't just change all of your ways and think of the other side for a change, can you? You want to continue this war until Nintendo gets it. You don't want to back down now. You can't even think a little about why region locking still exists in 2011 before assuming that Japan hates you. Europe gets one nice thing for once in their entire miserable gaming history and rather than be happy about it, you're consumed with jealousy. You want more. You want to be equal. America built its history on complaining that things aren't right and you don't want to turn back on that legacy. I'm afraid that's not how life works. That's not how this industry works. You're either for or against Nintendo in this case, and a large number of the combatants are lukewarm. They want very badly for Nintendo to deliver, but they will still support them until they do. What kind of movement is this, again? I find it hard to believe so much is at stake when not nearly enough people are taking this movement seriously enough to realize this.
Even if Operation Rainfall goes absolutely perfectly and follows the above plan by holding their support to Nintendo hostage until their demands are met, they're still only a small fraction of Nintendo's customers. If you feel offended that I'm insinuating that you are one of the irrational people who shout before they think, I would like to remind you that you are the minority. The vast majority of people being heard are the ones typing in all caps why Nintendo sucks and that they're going to pirate and be proud of it, neener neener. There is nothing that can be done for them. Sadly, they're the ones representing your movement, not Operation Rainfall. They're the ones on the front lines disregarding Operation Rainfall's tiny notice to not pirate. They're the ones calling Nintendo the enemy. They're the ones who make it on the news. If Operation Rainfall succeeds, these fans are the ones who are going to take the credit. I shudder to think that they'll take the credit for making Nintendo do something they were going to do in the first place but weren't able to at the time the fans wanted. It won't be a victory for mistreated fans. It will be a victory for greedy fans.
YOUR FAULT
We've gotten to the point where when one promise is broken, dreams are shattered. It makes so much sense for Nintendo to publish three little games, and yet they don't. Rather than think about what reasons they have for doing so, we call bloody murder and throw fits on the internet. We have to resort to full-scale campaigns just to get something that we obviously should have gotten years ago or even games that we shouldn't get due to real quality concerns by the developers. This is some democracy we gamers have built. Countless people are proudly proclaiming that they are going to pirate without regard for the consequences. They claim that Nintendo forced them to turn to crime just so they can play some games. This is obviously not true; no one has forced you to do anything. But no one listens, and the war rages on. So who is to blame for this? Who allowed the state of gaming to get to the point where we have to petition in the first place? Who is the real enemy here?
Everyone. Everyone in the world, without exception. I blame Mistwalker for acknowledging the international support and starting this whole mess. I blame Nintendo of Japan for not being built to handle this kind of feedback. I blame Nintendo of America for that Facebook post that fanned the flames to record highs. I blame Destructoid and all other sites like this for encouraging the poor behavior on the part of the fans. I blame the fans for not knowing better. I blame Nintendo's shareholders for not sharing the fans' opinions on this matter. I blame whoever thought region locks were a good idea, and I'm 100% positive that they aren't involved in video games. I blame fan translators for taking away incentive to learn the original language. I blame you personally for being a part of the problem. But most importantly, I blame myself for not noticing any of this sooner. The problems that led to this are far too advanced to do anything about them now. Despite what I or anyone else who thinks as I do say, there will still be unstoppable crowds of complainers at Nintendo's door and there will still be petitions organized by idealists who still don't get it. They never will. They're too set in their greedy ways to sympathize with Nintendo's problems, instead content with savaging them for falling off their pedestal. They're all fighting the wrong fight and nothing can be done to set them on the right track. Somewhere along the line, things got out of hand and nobody did a thing about it. It's simply too little too late.
Therefore, my message to you, the reader, is this: Give it up. Just stop. You do not matter as much as you think. Nintendo will survive despite you. They don't care about you, so you should not care about them. Be thankful that we got anything at all from Japan while they fear us mighty Westerners so much. I would say that you should either get supporters from a demographic that matters or do Nintendo's job for them since they obviously won't, but that's not going to happen. Not on a site like this, where not even my older brother, who is much more hardcore than me, dare tread. It's a lost cause. Just let it go. Let these titles stay in Japan, where they belong. Just cut your losses and be happy for someone else for a change. You'll live longer if you do. If we were truly meant to get these games, we will. Nintendo is not stupid. We don't need to petition. We need to be adults. And if you still can't accept that message, these fellows said it much better than I ever could.
Welcome to the minority.
La-Mulana is one of the few upcoming games I'm looking forward to. Fortunately, I discovered just in time that the developers were holding a Ustream of their panel at the Tokyo Game Show, which I was able to capture and put on YouTube. Regrettably, I was not able to save the chat, which brought up a few points I didn't record.
Highlights:
Hell Temple is DLC. No price or release date has been set at this time.
The bosses shown are drastically updated.
Mantras are accessible from the pause screen.
Many more traps in previously safe areas.
Release date is targeted for this year.
Some people actually asked me if I ever got my copies of Sakura Wars 1-4 to run. After discussing it with a professional, we concluded that my Dreamcast had somehow lost the ability to execute signed code, meaning I had to get another. Luckily, a local used game store had a bunch of Dreamcast stuff at very reasonable prices. A few solder points and burned discs later and I'm now in the possession of a Japanese Dreamcast with a black swirl in its boot-up splash, two controllers, a giant box with 10 discs I can actually play now and some of my favorites from back in the day: NBA Showtime, Power Stone 2 and Ready 2 Rumble (only the demo of which I actually played in the past). However, that soldering turned out to be completely pointless since I still need a boot disc to run imports for more than ten minutes. What's all that about? I could change its region back to American, but I'm not going through all of that unscrewing again any time soon, especially since now I sometimes have to close the disc door twice to get the drive to spin. Anyway, to justify this blog I guess I'll write up some (re-)impressions.
Sakura Wars isn't an entirely new experience for me. My Social Link training is coming into play here, but I'm less than an hour in and already I'm beginning to see why people appreciate it. In Persona 3 and other dating sim-like games, I'm inclined to do the engineer thing and carefully consider every option given when I'm presented with a branch instead of answering impulsively like I think I should. Here, I don't get that opportunity. If you haven't been following the news of the English release, when you encounter a dialogue option, you get only a few seconds (3-10) to think about what you say. You're always on your toes and always under pressure because the more important ones take you by surprise. The LIPS system as it's known is quite flexible, as demonstrated very early on: in one event, I found myself at the door of the dressing room looking for one of the performers of a play about to open. I was given a single choice: open the door. I did the gentlemanly thing and waited out the 10 seconds until it went away and was rewarded for it. I can't wait to see what combat is like, but to play it I need to have my laptop next to my television because I'm not printing out 100 pages and flipping through them like a madman. I recently had to change out the power strip to one with only six plugs instead of seven and my laptop battery will last for all of three seconds (literally), so until I come up with a workaround for all of that, it will have to wait just a little longer. Time will tell if this was worth the effort.
For whatever reason, NBA Showtime, or as I've always known it, NBA on NBC, was always my favorite sports game. There's nothing remarkable about it: it's your standard 2-on-2 basketball game with a character editor. It's no different now. I think what captivated me a decade ago was its commercial tie-in. I thought the idea of playing something based on a non-fictional television show was the coolest thing. The inclusion of all of the NBC markings and voices ("This is the NBA on NBC") strengthened that impression. It just seemed so authentic and real back in the day despite the fact that my older brother always played an emaciated horse man nicknamed "Phat". I remember one time my little sister tried playing it. She held the controller upside-down and managed to score a 3-point shot. How broken is that?
Power Stone 2 is just as chaotic as I remember, even on single-player. I still find it a little hard to believe that it actually came out in the arcades because it feels much more at home on a console. I hear that there's a PSP compilation that combines this and the first game out now, but I have yet to come across it. All I know about the first game is that the players get five lifebars instead of just one.
I can't believe that someone at Midway thought that a single first-person camera for a two-player game would be a good idea. Ready 2 Rumble becomes a very interesting experience when only one of you can actually see your fighter. It might be one of the few second-person games in existence. Also, don't try maximizing the time and round count to the regulation setting of 12 three-minute rounds because odds are you won't make it to the second round if you don't fully remember how to play. I've heard nothing but bad things about the Wii remake and I'm guessing that's because this is just Fight Night for Morons with one analog stick and a single memorable character: Afro Thunder.
Maybe one day I'll do the right thing and pick up a proper copy of Seaman on eBay. After that maybe I could find some shmups and get a PS-to-Dreamcast adapter so I can use my stick on it. Also, would anyone be interested in taking that clock off my hands?
I have no idea what to do with any of this. Playing them is certainly out of the question and I don't have any safe place to store them. No clue what the lanyard is for, by the way.
Dreamcast is retro, right?
I wanted to just post this in the forum, but since I've posted a blog about Card Sagas Wars preview videos in the past, I figured I should follow with another. This video shows that more of the cards in the frankly impressive gallery than previously thought will be in the game. In particular, the Green Series cards, none of which have gallery entries yet, are demonstrated as strikers that can be triggered after sustaining damage. This mechanic finally explains what the letters on the cards refer to: they indicate the strength of supporting attacks by that card. Earlier updates explain that combos and special attacks are done by inputting very simple button commands, making it more like a party fighter and less traditional. I don't think MUGEN has ever been implemented this way. Its release cannot come soon enough.
The last five seconds of the video are golden. Also, I call dibs on Soma Cruz. | v0 |

Here are some links to information and projects related to Linux system size.
Contents
Documentation on reducing kernel size
There is a draft of a comprehensive document on the subject of measuring and reducing the size of the Linux kernel following page:
Kernel Size Tuning Guide
Technologies for decreasing system size
The Linux-tiny patchset
• see the Linux Tiny page. There is a project to characterize the sub-patches in the Linux-tiny patchset, in order to prioritize them for porting to non-x86 architectures.
• see Linux Tiny Test Project
Compiler options for reducing kernel size
An LWN article talks about three gcc options to shrink the kernel.
Shrinking the Kernel with GCC
The first option is -Os which is already in the tiny kernel patch.
The second option is new in gcc 3.4, -funit-at-a-time. This apparently makes gcc do a much better job of inlining and dead code removal. It reduces the size of both text and data. It depends on another inlining patch that I think is in the tiny kernel patch (maybe same idea but different details).
The third option, -mregparm=3, seems to be x86 specific, it instructs the compiler to use registers for the first three function arguments. by John Rigby
SquashFS file system
For read-only data, it is useful to utilize a compressed file system. The following are used heavily in embedded systems:
• Cramfs - [should put some information or link here]
• SquashFS - see the Squash Fs page
Use of a smaller libc
• uClibc - small footprint but complete C library
• klibc - very small library for use in init ram filesystems
• dietlibc - another library to produce very small statically compiled executables.
• Subset Libc Specification - CELF is researching the possibility of creating a subset libc specification
Kernel XIP
By executing the kernel in-place from flash, it is possible to save RAM space.
Application XIP
By executing applications in-place from flash, it is possible to save RAM space.
• see ApplicationXIP
Data Read In Place (DRIP)
This is a technique for keeping data in flash, until it is written to, and then making a RAM page for it.

How to measure the memory usage at runtime
See Runtime Memory Measurement for a description of ways to measure runtime memory usage in Linux.
Also, see Accurate Memory Measurement for a description of techniques (and patches) which can be used to measure the runtime memory more accurately.
Linux size increase from 2.4 to 2.6
Linux increased in size by between 10% and 30% from version 2.4 to 2.6. This incremental growth in kernel size has been a big concern by forum members.
Please see the Szwg Linux26Data page for supporting data.
GCC Code-Size Benchmarking
CSiBE is a code size benchmark for the GCC compiler. The primary purpose of CSiBE is to monitor the size of the code generated by GCC. In addition, compilation time and code performance measurements are also provided.
CSiBE
Case Studies
• Motorola reduction of system size (presumably for cell phones) using 2.4 Linux: see Mot Size Reduction.ppt
Other Tidbits on System Size
Memory leak detection for the kernel
Catalin Marinas of ARM has been recently (as of 2.6.17?) been posting a memory leak detector for the Linux kernel. It may get mainlined in the future. Here's a link to the LKML discussions around it: http://lkml.org/lkml/2006/6/11/39
How System Size may affect performance
It has long been theorized that reducing system size could provide a performance benefit because it could reduce cache misses. There does not appear to be hard data to support this theory on Linux, but this has been discussed on the kernel mailing list.

The Great barracuda (Sphyraena barracuda) is a large predatory fish in the Family Sphraenidae that is found worldwide in tropical waters.
Great barracuda. © 2004-08 Florent Charpin
Scientific Classification
Kingdom: Animalia (Animals)
Phylum:--- Chordata
Class:------ Osteichthyes (Bony Fishes)
Order:-------- Perciformes
Family:-------- Sphraenidae (Damselfishes)
Genus:----------Sphyraena
Species:--------- Sphyraena barracuda (Edwards, 1771)
Physical Description
Great barracudas are long (0.45 to 2.00 meters) silvery fish, with large scales, and may grow to 50 kilograms in body mass. The species pointed head ends in a large mouth that contains two rows of knife-like teeth. The lower jaw projects beyond the upper jaw, which feature is helpful in biting.
They are a grayish brown above and silvery below, which color combination is quite universal throughout the geographic range. They often have dark ink-like spots that are arranged in no particular pattern on their sides. The young have dark crossbars on their backs and blotches on their sides. The young also have a soft dorsal fin, with anal and caudal fins manifesting as blackish. Males and females are superficially indistinguishable to humans.
Distribution
Distribution of the Great barracuda. Florida Museum of Natural History.
This species is almost always found in warm seas. In the Indo-Pacific they are found in the Red Sea, and from the east coast of Africa to Hawaii and the Marquesan and Tuamoto Islands. In the Western Atlantic they are occur from Massachusetts (USA) and Bermuda throughout the Caribbean Sea to Brazil. In the Eastern Atlantic they occur in Sierra Leone, Côte d'Ivoire, Togo, Nigeria, Senegal, Mauritania, St. Paul's Rocks, and São Tomé Island.
Habitat
Adult Great barracudas live in and around the edges of coral reefs at depths ranging from one to 100 meters, most commonly between three and 30 meters. They tend to avoid brackish water unless they are getting ready to spawn. Juveniles occur among mangroves, estuaries and shallow sheltered inner reef areas. When adults attain a large enough stature to protect themselves, they move out into the open ocean and then to the margins of the coral reefs.
Feeding Behavior
Great barracuda chiefly consume fish, but they also feed on cephalopods and shrimp. Their large teeth are quite useful for capturing fish prey. They have a large gape which allows them to feed on extremely large fish by chopping them in half. They devour what they can catch using their combination of a sit-in-wait and active predator style. Their narrow head-on profile and silvery color reduces their visibility to prey. They feed on both bottom-dwelling species as well as species of the higher water column. They rely on their acute vision to locate prey. Great barracudas may herd schools of fish into shallow water and guard them until their previous meal has been digested, and they are hungry again.
Behavior
S.barracuda is usually a solitary fish in its adult phase, especially at night. Juveniles and adults may form groups during the day, sometimes containing hundreds, or even thousands, of individuals.
Great barracudas are inquisitive and may follow divers or snorkelers. However, attacks by barracudas on humans are very rare, and may most often occur when the fish attempt to take food from spear fishers .
Reproduction
It is still unclear about the timing and location of spawning of the Great barracuda. In fact, great barracudas appear to show different spawning patterns in different areas of the world. They typically spawn in shallow waters such as estuaries. Great barracuda do not care for their fertilized eggs, which drift out into the ocean, and after hatching the larvae enter the planktonic stage. The larvae settle in shallow areas on the margins of clear-water estuaries. When the larvae reach about 30 centimeters they move to open waters and eventually they move out of the estuaries completely when they reach about half a meter in length. They reach sexual maturity at 60 centimeters and may live for about 14 years.
Associations
As juveniles, these fish compete for food supplies with needlefishes and small snapper. This competition consists of killifishes, herrings, sardines, gobies, silversides, anchovies small mullets, and lizardfishes to name a few. As the fish get older and bigger, they may compete with larger fish like mackerel, or even dolphins, depending on their habitat
The Great barracuda may be parasitized by fish, such as remoras or pilotfish, that attach to their bodies and use them as a source of propulsion.
Conservation Status
The Great barracuda is not listed as a threatened or endangered species.

Survey into impacts from Queensland disasters
19 March 2012
Business operators in areas of Queensland affected by Tropical Cyclone Yasi and the 2011 floods in southeast Queensland will have an opportunity this month to highlight their experiences.
Geoscience Australia will circulate a survey to a total of 1900 businesses to gather information on the impacts and losses attributable directly to the events as well as the disruptions they caused to business revenue and operations. It will seek details also on how businesses coped with that loss and disruption.
Geoscience Australia researcher, Shelby Canterford, said the information will help to develop a better understanding of various effects on the business community and assist with planning to help mitigate problems encountered by communities as a result of natural disasters.
"Information from Tropical Cyclone Yasi and the 2011 floods will complement existing knowledge about natural hazards and their impact on buildings and other structures," she said.
"Understanding the impacts on businesses is important to developing an appreciation of the community's economic vulnerability to disasters," Mrs Canterford said.
Businesses willing to participate in the survey can complete it online at:
2011 Floods: https://www.surveymonkey.com/s/2011flood;
Tropical Cyclone Yasi: https://www.surveymonkey.com/s/TCYasi; or
by emailing Geoscience Australia Hazards: [email protected].
The survey of the business community will be followed by a survey of households which will focus on gathering information on the social impacts of a disaster.

How Urban Planners Use Web-Based Crowdsourcing
One of the most difficult things for urban planners to do is to garner accurate and worthwhile public opinion. Coincidentally, public opinion happens to be the driving force behind the concept of “urban planning.” After all, planners exist to serve the public, and if they can’t figure out what the public’s opinions are on construction and design issues, then there’s no way for them to do their job effectively.
As many would argue, this speed-bump in the planning process could be due to the lack of awareness and/or availability of the public to attend scheduled zoning, policy, or planning forums. These meetings, which usually include overviews of potential construction projects and developments going on in the community, are crucial to any bottom-up planning division. Unfortunately, many valued members of the general public don’t have the time or transportation means of attending these meetings to express their opinions.
There have been recent attempts, however, to remedy this situation with input from the general public garnered via web-based crowdsourcing. As Planning Theory states, “The medium of the web enables us to harness collective intellect among a population in ways face-to-face planning meetings cannot.” With web-based crowdsourcing, there are minimal time constraints, and nearly everyone would be able to give their input to planners. Awareness of planning topics could even be promoted via email marketing or social media marketing.
As seen in this thesis on public participation in transportation planning, web-based crowdsourcing has seen success in trial runs in the past. As the report describes, “The collective intelligence of communities is largely untapped by traditional [public participation] methods, which may result in less-than-ideal transit plans that neglect the needs of diverse constituencies.” The thesis found that utilizing web-based crowdsourcing was “effective in many ways,” including higher-than-normal volumes of participation and a diverse amount of participants.
The use of web-based crowdsourcing has a bright future in urban planning and public participation. What do you think planning departments should do when it comes to garnering more public participation in the planning process?

} | cccc_CC-MAIN-2013-20 | DCOM & related technologies
This is an article on DCOM & related technologies in Engineering Concepts.
The Component Object Model (COM) is a softwarearchitecture that allows applications to be built frombinary software components. COM is the underlyingarchitecture that forms the foundation forhigher-level software services, like those provided byOLE. OLE services span various aspects of commonlyneeded system functionality, including compounddocuments, custom controls, interapplicationscripting, data transfer, and other software interactions.
In information technology, a compound document is anorganized collection of user interfaces that form asingle integrated perceptual environment. A compounddocument includes a data structure that containsdifferent data types, such as text, audio files, andmotion video files. A compound document is also anapplication environment containing program objectsthat can be interlinked and interacted with by a user.
Compound documents can be formed of information partsthat originate from different sources and that areassembled on the fly. Microsoft's Internet Explorerdesktop uses the compound document concept.Microsoft's Object Linking and Embedding is aframework for assembling and managing compounddocuments. OpenDoc is an alternative standard.Component Object Model (COM) is Microsoft's frameworkfor developing and supporting program componentobjects. In object-oriented programming anddistributed object technology, a component is areusable program building block that can be combinedwith other components in the same or other computersin a distributed network to form an application.
Examples of a component include:�
• a single button in agraphical user interface
• a small interest calculator
• an interface to a database manager
Components can bedeployed on different servers in a network andcommunicate with each other for needed services. Acomponent runs within a context called a container.Examples of containers include pages on a Web site,Web browsers, and word processors.
It is aimed at providing similar capabilities to thosedefined in the Common Object Request BrokerArchitecture (COBRA), a framework for theinteroperation of distributed objects in a networkthat is supported by other major companies in thecomputer industry. Whereas Microsoft's Object Linkingand Embedding provides services for the compounddocument that users see on their display, COM providesthe underlying services of interface negotiation, lifecycle management (determining when an object can beremoved from a system), licensing, and event services(putting one object into service as the result of anevent that has happened to another object).
The reason for the broad use of COM technologies issimple: for a tremendously wide range of problems, COMallows the creation of better software.Using COM, objects (or classes) and their methods andassociated data are compiled into binary executablemodules, that are, in fact, files with a dynamic linklibrary (DLL) or EXE file name suffix. A module cancontain more than one class.COM allows components of an application to be split upamong different, computers. Because of COM local andremote transparency the client access a component without the knowledge or concern of where the component isrunningHere are some of the facts about COM today:
• COM is in use on well over 150 million systemsworldwide.
• COM consists of a well-defined, mature, stable, andfreely available specification, as well as a referenceimplementation, which has been widely tested andadopted worldwide as a de-facto standard.
• COM provides the richest set of existing servicesfor applications today, as well as the largest set ofdevelopment tools available from a wide variety ofvendors.
• COM supports the only currently viable componentmarketplace. The market for third-party componentsbased on COM has been estimated at US$670 milliondollars in 1998, with a projected 65 percent compoundannual growth rate, growing to approximately US$3billion dollars by 2001. (Source: Giga InformationGroup)
• COM supports thousands of available applications,including all of today's highest volume applications.Major system vendors such as Hewlett Packard, DigitalEquipment Corporation, Siemens-Nixdorf, and SiliconGraphics have announced plans to ship COM on UNIX andother operating systems within the year, with morevendor commitments on the way.
• COM is supported by the largest number ofdevelopment tools available for any component orobject model on the market.
COM includes COM+, Distributed Component Object Model (DCOM), and ActiveX interfaces and programming tools.The Component Object Model (COM) and its relatedCOM-based technologies of DCOM, COM+, MTS and ActiveX�comprise the most widely-used component software modelin the world.
ActiveX:
ActiveX is the name Microsoft has given to a set of"strategic" object-oriented programming technologiesand tools. The main technology is the Component ObjectModel (COM). Used in a network with a directory andadditional support, COM becomes the DistributedComponent Object Model (DCOM). The main thing that youcreate when writing a program to run in the ActiveXenvironment is a component, a self-sufficient programthat can be run anywhere in your ActiveX network(currently a network consisting of Windows andMacintosh systems). This component is known as anActiveX control. ActiveX is Microsoft's answer to theJava technology from Sun Microsystems. An ActiveXcontrol is roughly equivalent to a Java applet.If you have a Windows operating system on yourpersonal computer, you may notice a number of Windowsfiles with the "OCX" file name suffix. OCX stands for"Object Linking and Embedding control." Object Linkingand Embedding (OLE) was Microsoft's program technologyfor supporting compound documents such as the Windowsdesktop. The Component Object Model now takes in OLEas part of a larger concept. Microsoft now uses theterm "ActiveX control" instead of "OCX" for thecomponent object.
One of the main advantages of a component is that itcan be re-used by many applications (referred to ascomponent containers). A COM component object (ActiveXcontrol) can be created using one of several languagesor development tools, including C++ and Visual Basic,or PowerBuilder, or with scripting tools such asVBScript.
Currently, ActiveX controls run in Windows95/98/NT/2000 and in Macintosh. Microsoft plans tosupport ActiveX controls for UNIX.
DCOM:
DCOM (Distributed Component Object Model) is a set ofMicrosoft concepts and program interfaces in whichclient program objects can request services fromserver program objects on other computers in anetwork. DCOM is based on the Component Object Model(COM), which provides a set of interfaces allowingclients and servers to communicate within the samecomputer (that is running Windows 95 or a laterversion).
For example, you can create a page for a Web site thatcontains a script or program that can be processed(before being sent to a requesting user) not on theWeb site server but on another, more specializedserver in the network. Using DCOM interfaces, the Webserver site program (now acting as a client object)can forward a Remote Procedure Call (RPC) to thespecialized server object, which provides thenecessary processing and returns the result to the Webserver site. It passes the result on to the Web pageviewer.
DCOM can also work on a network within an enterpriseor on other networks besides the public Internet. Ituses TCP/IP and Hypertext Transfer Protocol. DCOMcomes as part of the Windows operating systems. DCOMis or soon will be available on all major UNIXplatforms and on IBM's large server products. DCOMreplaces OLE Remote Automation.
DCOM is generally equivalent to the Common ObjectRequest Broker Architecture (COBRA) in terms ofproviding a set of distributed services. DCOM isMicrosoft's approach to a network-wide environment forprogram and data objects. COBRA is sponsored by therest of the information technology industry under theauspices of the Object Management Group (OMGDCOM is simply "COM with a longer wire"-a low-levelextension of the Component Object Model, the coreobject technology within Microsoft� ActiveX�.
Majordevelopment tools vendors-including Microsoft,Borland, Powersoft/Sybase, Symantec, ORACLE, IBM, andMicro Focus-already sell software development toolsthat produce ActiveX components. These tools and theapplications they produce automatically support DCOM,providing the broadest possible industry support.Additionally, over 1,000 existing commercial softwarecomponents that will work with DCOM are alreadyavailable for use by developers.�
COM+:
COM+ is an extension of Component Object Model (COM),Microsoft's strategic building block approach fordeveloping application programs. COM+ is both anobject-oriented programming architecture and a set of operating system services. It adds to COM a new set ofsystem services for application components while theyare running, such as notifying them of significantevents or ensuring they are authorized to run. COM+ isintended to provide a model that makes it relativelyeasy to create business applications that work wellwith the Microsoft Transaction Server (MTS) in a Windows NT or subsequent system. It is viewed asMicrosoft's answer to the Sun Microsystems-IBM-Oracle approach known as Enterprise JavaBeans (EJB).
Among the services provided by COM+ are:
• An event registry that allows components to publishthe possibility of an event and other components tosubscribe to be notified when the event takes place.For example, when a sales transaction is completed, itcould trigger an event that would allow other programsto be notified for subsequent processing.
• The interception of designated system requests forthe purpose of ensuring security.
• The queues of asynchronously received requests for aservice.
A "component" is a building block program that isself-describing. This means that it can be run with amix of other components and each will be able tounderstand the capabilities and characteristics of theother components. Practically, this means that a newapplication can be built by reusing components alreadyknown to exist and without having to compile theapplication. It also makes it relatively easy todistribute different components of an applicationamong different computers in a network. Microsoft'sDistributed Component Object Model (DCOM) addsinterfaces to do this.
In addition to its self-description, a componentconsists of one or more classes that describe objectsand the methods or actions that can be performed on anobject. A class (or coclass in COM+ terminology) hasproperties described in an interface (or cointerface).The class and its interface are language-neutral.Associated with the class are one or more methods andfields that are implemented in a specific languagesuch as C++ or Java or a visual programmingenvironment. When you instantiate a class, you createan object (something real that can be executed in thecomputer). Sometimes the term "class" is also used forthe instantiated object (which can be confusing).
MTS:
Microsoft� Transaction Server (MTS) is the transactionservice in the Windows NT� operating system. Firstavailable in 1996, MTS is now in use at manyorganizations. Enterprise JavaBeans (EJB) is aspecification for a Java-based transaction service.
Created by a group of companies led by SunMicrosystems Inc., the initial specification for EJBwas released in spring 1998. Both MicrosoftTransaction Server and Enterprise JavaBeans target thecreation of component-based, transaction-orientedapplications. This paper provides a comparison ofthese two technologies. More specifically, the paperanalyzes the similarities and differences between theways the two component models handle objects,transaction support, controlling complexity,portability, interoperability, language choice andadministration.
Put simply, a transaction can be thought of as a setof events that are committed or rolled back as aunit-either all of the events happen, or none of themdo. For example, transferring $100 from your savingsaccount to your checking account requires bothsubtracting the money from your savings account andadding it to your checking account. To achieve aconsistent result, either both operations should occuror neither one should. Transaction-orientedapplications like this are very common, and so manyvendors provide software that makes writingtransactional applications easier. And becausetransactional applications often need to handlehundreds or thousands of clients (i.e., users atworkstations), services that make it easier to buildscalable applications are commonly built into productsthat support transactions.
Both Microsoft Transaction Server and EnterpriseJavaBeans support transactional applications andprovide services for scalability. Because the twotechnologies attempt to solve many of the sameproblems, they have much in common. The easiest way toillustrate their similarities is to describe the basicarchitecture and terminology of each MTS is based on the Component Object Model (COM), andan MTS application is implemented as one or morecomponents.

} | cccc_CC-MAIN-2013-20 | 10 years of Bt cotton: false hype and failed promises
Ten years after Bt cotton first made its appearance in India, the Coalition for GM-free India has released this special report and demands an immediate halt to the policy of promoting Bt cotton.
In summary, the story of Bt cotton is clearly that of false hype and failed promises. Bt cotton has failed to meet its promise in terms of sustained yield gains, pest protection and reduction in pesticide usage. It is time for the government, scientists and policy-makers to reject the hype around Bt cotton, and focus on sustainable solutions and pro-farmer measures to achieve production, environmental safety and farmers’ welfare that are long-lasting.

October 11-13, 2012
Paris
For the fifth year running we, at OW2, are organizing the Community Summit at the Open World Forum (October 11-13, Paris). This year, free and open source software communities practitioners will debate on the changes brought by the emergence of cloud computing to the roles and functioning of free and open source software communities.
Today's cloud computing software innovation is mostly open source. Open source innovation leads in all compartments of the cloud computing stack: virtualization, VM management, security, file systems, monitoring, big data, broker, etc. A fertile terrain for free and open source software communities.
However, as we all know, what customers get with cloud computing is a service, not software. With cloud computing, software is hosted and vendors do not distribute it. Since the code is no longer circulating, improvements to the software are no longer shared.
Is cloud computing changing the fate of open source software communities? Open source software community members are the primary implementors of the software, they create value directly for the end user. With cloud computing, the value creators are the hosting companies; they mediate the software value creation process and they have the ability to generate new kind of proprietary lock-in, foe example at the data level.
Whereas IT freedom used to be broadly defined in terms of software accessibility, in the age of cloud computing it must now be defined in terms of service accessibility and data freedom. How do we define free service? Is open data the new open source? Is cloud computing a paradigm shift that makes open source claims irrelevant? What does “open” and “free” mean in the age of cloud computing? What new challenges are posed to free and open source software communities?

Community Summit details and abstracts: (to be completed progressively)
Speaker: Lars Kurt, Xen, Citrix.
Title: Cloud Computing and the Xen Community
Abstract: The Xen Hypervisor open source project was founded in 2003 as a direct result of Cambridge Universities XenoServer research project that defined Cloud Computing as we know it today. In 2006 Amazon Web Services built their business on top of Xen, followed by Slicehost and many other cloud and hosting providers. In other words: the Xen project provided the technology that enabled many multi-million dollar businesses to thrive. However, until recently cloud and service providers have not been active members of the Xen community. This talk will look at characteristics of the Xen community, its evolution over time, consider licensing and related topics. We will also look at incentives to engage service providers and help them become more active members of your open source community.
Biography
Speaker: Michael Meeks
Title: LibreOffice: turning vinegar into wine
Abstract: Come and hear the story of how the development community around LibreOffice was created from the ashes of the OpenOffice.org project. Hear some of the lessons we learned from both projects, and the ways we use to ensure that corporations play a constructive role with an interest in a diverse developer community. Hear a detailed rational for our release process, and how it helps to reduce problems around conflicting goals. Hear about our progress to date, see some community diversity metrics we track, and more. Finally enjoy a gratuitous plug for our new features and functionality.
Biography:
Michael is a Christian and enthusiastic believer in Free software. He very much enjoys working for SUSE where as the Linux Desktop Architect he tries to understand and nudge the direction of our Linux investment. He has appreciated working on various pieces of infrastructure and applications over the years: from GNOME office, through component technologies, to Evolution, Accessibility, MeeGo, and latterly LibreOffice much of the time. Prior to this he worked for Quantel gaining expertise in both hardware and software for real time on-line AV editing systems.
Speaker: Ross Turk
Title: The Dangers of Apathetic Abstraction
Abstract: What began as a vague shape on a diagram (indicating something so incomprehensibly vast the diagrammer decided against trying to draw it) has changed everything. Yesterday, the network was out of your control and too complicated to understand; now your entire operation is. But one thing hasn't changed: you probably don't care how most of it works, just that it continues to. Every day, scores of excited entrepreneurs build new companies on cloud infrastructure without a second thought. Every day, established companies relinquish their data centers. The reason is clear: it's far easier to build something amazing when you can stop paying attention to what makes large portions of it work. Abstraction is not having to worry how underlying technology functions; apathetic abstraction is not caring. This session will discuss how to avoid the danger of relying on something you don't control and don't understand.
Biography:
Ross Turk is Vice President of Community for Inktank, responsible for building a strategic relationship with users, contributors, and the open source community. Ross brings more than 15 years of experience creating software, managing complex IT systems, and helping companies understand and serve developers.

In the more distant past, Ross ran the engineering team for SourceForge and provided architectural leadership.
Speaker: Leslie Hawthorn, Red Hat
Title: Compromise and Collaboration: Engaging FOSS Contributors in the Age of Cloud Computing
Abstract: As FOSS communities look to bring on new contributors, we're faced with a fundamental challenge - our new would-be users, contributors and advocates are largely operating in a world of non-free software. While the fact that most folks are using proprietary software - and that FOSS advocates would prefer they use FOSS - is nothing new, the rise of cloud computing puts a different spin on the problem. The ease of use promised by software as a service applications, the ubiquity and popularity of non-free social networks and the great increase in non-free real-time communications tools presents us with a more difficult use case: how do we convince folks of the value of FOSS when they expect things to "just work" and want to "hang out" where their friends are? In this talk, Leslie Hawthorn will explore the tensions between effectively engaging our audience of would-be converts to FOSS while maintaining the values of software freedom. Specifically, she will explore the activist roots of the free software movement and how these activist principles can be channelled to effectively amplify the value of FOSS amongst users of cloud services and other non-free tools. Last but not least, she will discuss some libre tools that can be used in our community outreach activities, allowing us to effectively engage with our audience's user experience expectations while preserving software freedom in our discourse.
Biography:
An internationally known community manager, speaker and author, Leslie Hawthorn has over 10 years experience in high tech project management, marketing and public relations. In March 2012 she joined Red Hat, Inc., where she is responsible for Community Action & Impact on the company’s Open Source and Standards team. Prior to Red Hat, she served as Outreach Manager at Oregon State University’s Open Source Lab and as a Program Manager for Google’s Open Source Team, where she managed the Google Summer of Code Program, created the contest now known as Google Code In and launched the company’s Open Source Developer Blog.
Speaker: Dave Neary, Red Hat
Title: Do Androids Dream of Electric Sheep? Cultivating Empathy in Increasingly Disconnected Communities
Abstract: With the advent of communities which are distributed around the world, and increasingly with the professionalisation of Open Source development, we have seen the human bonds between participants in Open Source projects weaken. As projects grow, and we hit the limits of Dunbar's Numbers, newcomers have a higher bar to clear to become part of the group, and our sense of belonging decreases.
Project leaders have tried many approaches to mitigate the effect, but more and more our tools insulate us from human contact and turn collaboration problems into co-operation problems.
What can we do to ensure that our community members keep in mind that behind every user name is a person, that the sum of our interactions defines us as a community? In short, what can we do to encourage empathy in contributors

April 2009 Newsletter
[OW2 Newsletter - April 2009 - From the OW2 Management Office]
Dear OW2 Members, Dear All,
The first OW2 Annual Conference is over. We had 1200 individual registrations! This means OW2 is now among the main open source communities in the world.
Fortunately not everyone showed up; we wouldn't have had enough for all at the free beer party :-) We have uploaded for you the presentations and some pictures.
The next major event for us is LinuxTag in Berlin where OW2 is staging the "Enterprise Development" track. The full program is here.
In the meantime you might want to attend one of the webinars organized by the Europe Local Chapter; please register here first.
If you are a student, you should take part in our programming contest, we have 21 topics for you to practice your skills on OW2 projects.
I'd like to inform our project leaders that they can now take advantage of a new service we have negotiated specially for OW2 projects: an appliance factory!
And if you have some time left, download our new paper on OW2 strategy: we are not just an open source community, we are a
"platform" and this paper explains why.
Thank you for your support!
Cedric Thomas

Lewistown is a borough in and the county seat of Mifflin County, Pennsylvania, United States. It is the principal city of the Lewistown, Pennsylvania Metropolitan Statistical Area which encompasses all of Mifflin County. It lies along the Juniata River, northwest of Harrisburg. The number of people living in the borough in 1900 was 4,451; in 1910, 8,166; in 1940, 13,017; and in 2000, 8,998. The population was 8,338 at the 2010 census. It is the principal borough of the Lewistown Micropolitan Statistical Area. Of the four communities in the United States named "Lewistown", this borough is the largest.

History
the text in this section is copied from an article in Wikipedia
Early history
The borough was incorporated in 1795 and was named for William "Bill" Lewis, a Quaker and a member of the legislature, who was responsible for the designation of the borough, which was then known as the Village of Ohesson, as the county seat of Mifflin County.
During the late 19th century Mifflin County became the crossroads of the Commonwealth. Located near the geographic center of the state, the area became a hub for traffic moving in every direction.
Early roads crisscrossed the region, but it was the eventual construction of the Pennsylvania Canal and the railroads that followed that truly positioned Mifflin County as an economic force in the state.
Lewistown, as the major city in Mifflin County, saw its economy expand dramatically as entrepreneurs launched companies to construct canal boats or build inns offering lodging for travelers and workers.
At its zenith, Mifflin County was one of the busiest centers for cargo and passenger traffic in the United States. But with the demise of the canal system, Mifflin County eventually lost its place as a major transportation hub.
American Civil War
On April 16, 1861, Lewistown sent its Logan Guards, a militia group originally formed in 1858, to Washington, D.C. for its defense. They were one of only five companies, all recruited in Pennsylvania, to share the honor of being the first U.S. troops sent to the capital. Monument Square, situated at the intersection of Main and Market Streets in Lewistown, serves as a memorial to these men.
Tropical Storm Agnes
Lewistown lost its role as a major transportation hub, but still boasted a strong industrial economy until the early 1970s when the county's industries began a slow decline. A ruinous natural event in June 1972 would cripple the local economy and Lewistown has never recovered.
One June 19, Agnes made initial landfall along the Florida Panhandle as a weak Category 1 Hurricane. Agnes then proceeded through Georgia, South Carolina and North Carolina before she moved back over the Atlantic off the North Carolina coast on June 21.
After regaining strength over the Atlantic, she made landfall again over southeastern New York on June 22 and moved westward in an arc over southern New York into north-central Pennsylvania. She became nearly stationary over Pennsylvania by morning of June 23, but was soon absorbed by a low-pressure system that slowly drifted northeastward from Pennsylvania into New York.
Rainfall from storm over the Mid-Atlantic region ranged from 2-3 inches in the extreme upper basins of the Potomac and North Branch Susquehanna Rivers to near Shamokin, Pennsylvania, in the Main Stem Susquehanna River basin. An average of 6-10 inches of rain fell over the Mid-Atlantic region. The soil, already well watered by spring rains, could not absorb so much water so quickly.
While flooding from the Juniata River was somewhat controlled due to a dam at Raystown Lake, west of Lewistown, the county experienced extensive flooding from the river and major streams which resulted in the permanent closure of many businesses along the river. Most notably, the flood submerged much of the American Viscose Plant, then a division of FMC Corporation. The facility, located on the banks of the Juniata River across from Lewistown proper, manufactured rayon fiber (primarily for rayon-belted automobile tires), polyester and Avistrap.
FMC was one of two major employers in the area at the time, the other being the Standard Steel Works. The "Viscose" plant was only marginally profitable before the storm and the cost to reopen was prohibitive. (Ironically, the demand for rayon fabric for trendy clothing shot upward only a few years later.) Rayon production, and with it, thousands of good-paying jobs, moved to another FMC plant in Front Royal, Virginia. The Lewistown polyester plant reopened, but it rehired only a fraction of the previous workforce. The site eventually became the Mifflin County Industrial Plaza and a variety of businesses have come and gone since then.
Present day
While Lewistown did receive the prestigious All-American City award in 1973 for its rebuilding process following the disaster, many of the blue collar workforce left the area to head south, along with the companies which chose not to rebuild in Lewistown.
Lewistown is home to the Pennsylvania State Fire School, which is the only such facility in the state. Firefighting in Lewistown is very important, as volunteer firefighters have strong allegiance to the multiple independent fire companies in the borough to which they devote their time.
Today, Lewistown is still looking to rebuild, but is now overshadowed by nearby State College. Due to the growth of Penn State and the construction of a new highway system, Lewistown is now struggling to avoid becoming the last rest stop for travelers coming from the east on their way to State College.
The Embassy Theatre, McCoy House, Mifflin County Courthouse, Montgomery Ward Building, and Wollner Building are listed on the National Register of Historic Places.

O'Reilly's Radar: Remix Patterns
Tim O'Reilly delivers O'Reilly's Radar (click to enlarge)
Tim's keynote was on patterns for remixing. Patterns consist of three parts: an issue, a prescription, and examples. Here are some of Tim's patterns (I missed much of it):
Issue: A successful open source project consists of "small pieces, loosely joined."
Therefore: Architect your software or service so as to be used easily as a component of a larger system: keep it modular, document your interfaces and use a license that doesn't hinder the recombinations.
Example: missed it
Issue: There is great benefit to sharing your development efforts with users
Therefore: release early and often. Set up mechanisms for user feedback, bug reports and so on.
Issue: On today's web you no longer need to build or own all the components of your application.
Example: isbn.nu
Therefore: don't lock away the interfaces to your ecommerce application.
Issue: When devices and program are connected to the Internet, applications are no longer software artifacts, they're on-going services.
Therefore: don't package up new features into monolithic releases, rather, fold them in on a regular basis. Let your users into the process. Engage your users as real-time testers and instrument such that you know how new features are faring. Operate as if you're in perpetual beta.
Examples: Google, Flickr, del.icio.us, Safari U.
Issue: The key to competitive advantage in networked applications is the extent to which users augment your data with their own.
Therefore: Architect for participation beyond design and development.
Example: Amazon using its user's intelligence to create new value. Adding user data to their own.
Issue: Only a small percentage of user will go to the trouble of explicitly adding value.
Therefore: make participation the default, aggregating user data as a side-effect of their using your application.
Example: Flickr's defaults for sharing is for "everyone." The default for annotation is "open."
Issue: Many of the limiting factors from the physical world are absent on the Internet.
Therefore: Use the power of the computer to monetize niches formerly too small to be commercial.
Example: Google Ad Sense.
Issue: The PC is no longer the only access point for networked applications.
Therefore: Design your application from the get-go to integrate services and share data on multiple devices.
Example: iSync.
Issue: Social networking are a by-product of social application like email, instant messaging, photo sharing, and book buying.
Therefore: Architect your application to capture and share the social fabric underlying you application (rather than artificially constructing another.
Example: The ETech Attention Stream (which is displayed on a flat panel in the lobby).
Issue: As demonstrated by container shipping, IP packages, and HTML pages, a standard content-agnostic packet is the most effective way to ship for good and data.
Therefore: Understand the optimum "packet size" for your application domain and devise products that fit it.
Example: Books don't fit on a Web page. O'Reilly Make and the new Cookbook series are examples of repackaging content in an effort to more closely match the right "packet size."
Issue: When content is digital, it lends itself to being broken down and remixed.
Therefore: Create your business model so that it make money from the atomic units of your products.
Example: Safari U.
Although they're not patterns, Tim also mentions AJAX and Ruby on Rails. | v0 |

ABOUT THIS ISSUE
This publication updates the preliminary estimates released in Construction Work Done, Australia (cat. no. 8755.0) on 26 May 2010, and Dwelling Unit Commencements, Australia (cat. no. 8750.0) on 16 June 2010. The data in this publication are based on a response rate of approximately 96% of the value of building work done during the quarter. The data are subject to revision when returns from the following quarter are processed. Final data for the March quarter 2010 will be released in Building Activity, Australia (cat. no. 8752.0) on 13 October 2010.
CHANGES IN THIS ISSUE
There are no changes in this issue.
DATA NOTES
The trend estimates should be interpreted with caution as the underlying behaviour of building activity may be affected by initiatives within the Government stimulus package, which included the "Building the Education Revolution" (BER) program and the Social Housing Initiative as well as other developments associated with global economic conditions. As with the publication Construction Work Done, Australia (cat. no. 8755.0) BER impacts have been quantified and removed from the trend estimates because of its short term nature. For more details on trend estimates, please see paragraphs 28 to 30 of the explanatory notes.

We sell software online. Our international trial to purchase ratio is abysmal compared to US domestic. I'm trying to determine why? Some possible answers:
• Higher piracy overseas
• PayPal and PO are only purchase options
What other possibilities am I missing?
What can I do to help my int'l customer purchase my product?
NOTE: We sell a B2B product for US$399.

International vs US Domestic markets are fundamentally of different magnitude.
Not sure who your target audience is and whether they face the same issues your Software addresses.
The following may be some reaons:
1. Target Audience : Are they facing same issues you are trying to solve?
2. Visibility : Do you have some kind of advertisement/marketing in other Countries?
3. Price Point : Does it take local market information ?
4. Localization : !
5. Local partners : In many cases local partners will help to identify market opportunities
Good luck.

Probably it will be best that you reach out to those international users and ask them the same question. Give them incentives to participate in your survey.
My guesses would be:
• They don't see value for money.
• Its too expensive for them.
• Not enough payment options.
Piracy should not be an issue cuz it looks like your products targets enterprises and software houses.
share|improve this answer
What language is your software and documentation written in? If you haven't localized then it is clear that you really are trying to cherry-pick as opposed to getting involved in the lives of your customers.
Don't market by U.S. vs. world but by English vs. other languages.
share|improve this answer
Paypal has a poor international reputation as a payment scheme. I'd wager that at least some of your problem is associated with the fact that it's hard to pay you. Investigate more locally adopted payment forms, and seriously consider accepting bare credit card payments. Many corporate purchasers don't want to mess with a PO, but aren't authorized to sign up for a company paypal account.
share|improve this answer
This may sound trivial but do you give the option to view the price equivalent for different currencies? This would at least establish you as something to be used internationally and not just within the US.
share|improve this answer
The first thing you need to do is to break you sales into domestic and international. The world's a big place and different things will work for different places.
So start by analyzing your western European sales. The British are probably the best candidates to start with since there are almost no language issues. How are you sales there?
Also, you don't mention the source of your sales. Could it be that many of your sales in the US are word of mouth, and you need to generate that in other parts of the world too? Are you using Google ads?
Yes, there are large parts of the world where the ratio is going to be much lower than in the US, including India and China, though you can do well in India, since yours is a business tool.
share|improve this answer
I think rather than guess it would be best if you gave them some kind of offer to tell you why they're leaving. Say I'll give you a $10 certificate to whatever in return for 5 minutes of your time.
If you follow a systematic process, you'll find out pretty quick. Good luck.
share|improve this answer
Back when I sold software development tools in the mid-late 1990s we reckoned on 50% US, 50% "international" sales as a rough benchmark for an established product in an established market.
If you're new you will need to establish credibility outside the US before you'll see acceptable sales. In particular:
• You must have a full trial version that is unrestricted. $399 is a lot of money for someone (even a company) to ante up for software that can't be tested. Screencams etc. won't be enough, it needs to be the full version.
• Investigate whether you can create a lower band price point with reduced features.
• Get some buzz around the product on well respected blogs. Consider SO advertising: according to traffic India is the #2 destination for SO users.
• Don't worry about piracy too much, especially for a B2B product. Things like dongles, copy protection and whathaveyou really just get in the way. For B2B at that price point I'd consider a simple serial number and a call-home on startup.
• Make sure that you don't have latent cultural assumptions in your product or supporting material. For instance, most people outside the US (and Japan) have no clue about baseball, so samples that do e.g. baseball scoring will be completely incomprehensible.
• On uninstallation, consider opening a browser window to a page that has a simple text box asking why the user uninstalled the software. There's no need for an incentive.
Hope this helps, best of luck

A concrete example: our main product is made in EU and we have 50% sales in EU, 30% USA, 20% rest of the world. We sell only through paypal and bank transfers. Paypal is not a concern for selling in EU. We just offer the double currency pay buttons. Our site, forum and documentation is only in English - otherwise maintenance would be costly - and hardly anyone complains. Sales are good.
Your product seems linked to administrering Windows servers; consider that in the EU the penetration of Linux servers is probably higher than in the USA. Maybe you should do a version for Linux servers and windows clients?

Perhaps you could offer a bounty hunter for everyone that wants to translate your software to other languages (for example Spain and France are very nationalist countries and they would prefer the software translated).

International markets vary wildly. Some countries are very price sensitive, while others demand features. You have to tailor your marketing for each one.
-Price. Your $399 piece of software might sell well in first world countries like the US, but in developing economies like India, you probably have thousands of customers looking for something $99 to free due to the difference in market rates there.
-Payment. Even in the age of technology, payment through internet or electronic transfer is difficult. Each country has a different system of banking that can cause numerous issues. This forces customers and vendors to go through third party services adding an additional layer of cost. Very undesirable.
-Support. Customers still like to be able to pick up a phone and reach you when they are having difficulties getting your gadget to work. Problem is, your 2pm might be 2am for an international customer. Unless you have 24 hours international support, they might look closer to home.
-Awareness. Sure adwords and google work well for getting customers to your site, but not all countries have high internet connectivity. In some places printed media still rules. Find ways of getting an ad into a local publication or newspaper.
The best way to solve many of these problems is to start a channel sales program. Search for and develop relationships with overseas vendors who do business in these overseas markets. Work out contracts with them for pricing tailored to their location. They will be able to handle all the marketing and support a lot better than you in their own area. Just make sure they know the product inside and out.

I have a decade experience in software developement and specially web related applications. As a geek, I have a nice contacts but I do not see any of my contact turning into a perspective client. Recently I got an offer to incubate a small consulting firm inside another bigger firm. My firm will work in a specific niche. Say Mobile development consulting.
As of now I do not have any client and am dependent upon the various lead generation tools available on web.
My question is, I have heard bigger consulting firms do subcontracting, is there any specific process of becoming a subcontractors. And is this the right path to get into consulting business when we have bigger giants ruling.

Seems like you dont have any expeirence in sales. If you start consulting co you would need to do sales. Get yourself comfortable with that.
I think for consulting most important is to start building relationships. Try doing first projects really, really free and make sure people are happy about your results. Then start asking for recommendations. Then you can start slowly increasing the price.
Hope it helps Mark

Being a subcontractor just means you're not the prime contractor, nothing more nothing less - so no, there's nothing special about it. That said, some very large contracts require that a percent of the contract be subcontracted to disadvantaged business enterprises. On the other end of the spectrum, some contracts forbid subcontractors.
As for getting subcontracts, just find the people who have the primes, find out who writes the proposals, management the projects, handles outsources, etc. -- and make contact in a meaningful way to them; really depends on your pitch, meaning you're able to do something they can't, are a disadvantaged business enterprise, etc.
Honestly most bizdev on subcontracts comes down to building relationships, but professionally speaking, this is one of many great books on doing business development as a consultant, "Rain Making: The Professional's Guide to Attracting New Clients".

Lawal Sa'adu, M. A. Hashim, Karsono A. Dasuki, Bahrom Sanugi
Abstract
This paper discusses the numerical solution of the 1-dimensional Schrödinger equation using method of lines approach (MOL) where the spatial dimension is discretize using some finite difference approximation leaving the time dimension to be the only independent variable in the resulting system of initial value problems. The effect of changing the discretization size on the stability of the solution procedure with respect to the absolute stability property of the numerical method used has been studied. In the study the use of Simpson’s rule in MATLAB has also been incorporated. The result indicates that there is some relationship between the discretization size and the convergence property. Further work will look into the modeling this equation to the application in Physics.

} | cccc_CC-MAIN-2013-20 | To Study the Prevalence of Chronic Respiratory Morbidities and Related Epidemiological Factors among Spinning Mill Workers
Ajeet Vasantrao Saoji, Deoke Aniruddha, Kulkarni Meenal, Nayse Jaydeep, Abhay Bhausaheb Mudey
Abstract
Background: Cotton and synthetic textile industry in India is the largest industry in the country accounting for 14 percent of industrial output and providing employment to around 35 million workers. The workers are at risk of suffering from various chronic respiratory illnesses like byssinosis, chronic bronchitis due to exposure to the cotton dust in the worksites. Even though quite a few studies have been conducted in textile mills in India enough emphasis has not been given on the epidemiological aspects of chronic respiratory illness among the workers in these mills. The present study was, therefore, undertaken with two fold objectives to determine prevalence of respiratory morbidities and to find out the epidemiological aspects of the respiratory morbidities in spinning mill workers.
Methodology: A Cross sectional study was conducted among 462 cotton textile workers in Babashaheb Kedar Sut Girni Pvt. Ltd. of Central India. Interview technique was used to collect sociodemographic, anthropometric & addiction information on a predesigned proforma followed by detailed general and systemic examination.
Results: Present study revealed that among 462 workers (25.3%) workers had chronic respiratory morbidities. The morbidities included Byssinosis (11.7 %), chronic bronchitis (5.8%), Bronchial asthma (4.5%), Tuberculosis (1.5%), other obstructive pulmonary diseases (1.7 %) All the workers were male and age ranged from 21 – 58 years. Majority of the study subjects i.e. 97.4 % were literate and 94.6% belonged to class III & IV according to modified Kuppu swamy’s classification. The spinning process was carried out in seven main sections. Majority of the workers belonged to ring frame section (47%). The present study showed that (32.7%) had cotton dust exposure for more than 20 years. Only masks were provided as protective devices and (41.3%) of the workers were using it. Total (34.7 %) workers were smokers.
Conclusion: Advancing age, sections, duration of exposure, non usage of protective devices and smoking were seen as major determinants of chronic respiratory morbidities in spinning mill workers.
Key Words: Spinning Mill workers, smoking, Byssinosis, chronic respiratory morbidities

Perfect Multiweapon Fighting [Epic]
Prerequisite
Dex 25, three or more hands, Greater Multiweapon Fighting, Multiweapon Fighting.
Benefit
The character can make as many attacks with each extra weapon as with his or her primary weapon, using the same base attack bonus. The character still takes the normal penalties for fighting with two weapons.
Normal
A creature without this feat can make only one attack per round with each extra weapon (or two attacks per round with each weapon if it has Multiweapon Fighting, or three attacks per round with each extra weapon if it has Greater Multiweapon Fighting). Each attack after the first extra attack has a cumulative –5 penalty.
Special
This feat replaces the Perfect Two-Weapon Fighting feat for creatures with more than two arms.

Stunning Fist [General]Edit
PrerequisitesEdit
Dex 13, Wis 13, Improved Unarmed Strike, base attack bonus +8.
BenefitEdit
You must declare that you are using this feat before you make your attack roll (thus, a failed attack roll ruins the attempt). Stunning Fist forces a foe damaged by your unarmed attack to make a Fortitude saving throw (DC 10 + 1/2 your character level + your Wis modifier), in addition to dealing damage normally. A defender who fails this saving throw is stunned for 1 round (until just before your next action). A stunned character can’t act, loses any Dexterity bonus to AC, and takes a –2 penalty to AC. You may attempt a stunning attack once per day for every four levels you have attained (but see Special), and no more than once per round. Constructs, oozes, plants, undead, incorporeal creatures, and creatures immune to critical hits cannot be stunned.
SpecialEdit
A monk may select Stunning Fist as a bonus feat at 1st level, even if she does not meet the prerequisites. A monk who selects this feat may attempt a stunning attack a number of times per day equal to her monk level, plus one more time per day for every four levels she has in classes other than monk.
A fighter may select Stunning Fist as one of his fighter bonus feats.

Libya: Obama Speaks, Tweeps Heckle
This post also available in:

Español · Libia: Obama habla, los tuiteros le reprochan
This post is part of our special coverage Libya Uprising 2011.
United States President Barack Obama broke his silence on Libya in a speech at the White House on Wednesday, but his words did little to satisfy the listening masses on Twitter who for the most heckled the president in tweets throughout the speech.
Without mentioning Libyan leader Colonel Muammar Gaddafi by name, Obama condemned the violence unleashed on Libyans since anti-government protests began on the night of February 16 (#Feb17) and offered condolences for those killed.
Obama said that Secretary of State Hillary Clinton would soon be meeting with the Human Rights Council in Geneva, and offered the following condemnation:
The suffering and bloodshed is outrageous, and it is unacceptable. So are threats and orders to shoot peaceful protesters and further punish the people of Libya. These actions violate international norms and every standard of common decency. This violence must stop.
The United States also strongly supports the universal rights of the Libyan people. That includes the rights of peaceful assembly, free speech and the ability of the Libyan people to determine their own destiny. These are human rights. They are not negotiable.
On Tuesday, Gaddafi delivered a furious, rambling speech, calling for death to anyone who threatens his rule.
Below, is a selection of tweets made during Obama's speech.
@mafouad: Obama condemns use of Violence n Libya adding “The entire world is watching”. Isnt the “watching” piece that got us where we freekin are!
@Abdulla_AlAthba: Obama offered nothing to Libya, he is just selling nice words in silly way, and insulted us #Libya #Gaddafi #Obama #SecClinton #Tripoli
@Kim_AE: Is it a coincidence that Obama waited to condemn the violence in Libya till the UN did so on Tuesday? http://tinyurl.com/4tjxat9
@JacksonDiehl: Gaddafi was surely worried about US military intervention–instead, Obama announces a meeting of the UN Human Rights Council #Libya
@PressSecret: After 9 days of silence, commenting on Libya Obama fails to condemn or mention genocidal Gaddafi by name. Strange. || #Obama #Gaddafi #Libya
@MassimoBianchi1: I am tired to see obama speech he need to take actions in LIBYA RIGHT NOW!
@bangkolo88: It is a nice thing that Obama has finally involve in the crises in Libya. But we wish he was clearer on his plan of action.
@ranty_man: Obama finally comes out with a statement on Libya now that the outcome looks certiain
@tristamsparks: hey #Obama the world has been watching #Libya for 8 days. #hardlydecisive
@EmyDib: @seedsown the thing in times like these how soon is soon enough!? #Feb17 #Libya #Egypt #Obama #Algeria
@obamafoodorama: #Obama took no questions after he made his statement on #Libya. #Clinton made no statement.
@alienmedia: #Bahrain & #Yemen were NOT in Obama's speech on #Libya. Urged for peaceful transition to democracy in #Tunis & #Egypt. http://bit.ly/gAf2L6
@Algerian_Dude: President Obama didn't say suffering and bloodshed in #Gaza is “outrageous & unacceptable” #Libya
@Pkatt: @aldamario Lets see what Obama does… Im bettin nothing but a stern look and a tongue lashing.. YOU? #p2 #tcot #ocra #teaparty
@MagButter: One common thing between #Obama & #Gaddafi: Both speeches are useless! #Libya #Feb17
@klaus_eduard: #Obama basically said US won't irritate #Gaddafi until US citizens are out. Should have been out long time ago. Will he ever act? #Libya
@StephenMullen: Dear Obama, Gaddafi is respecting the rights of Libyans. It's a dictatorship, they have none. That what the protests are about.
@AliTweel: so, Obama has no deal with Libya, but Gaddafi says this revolution is all made by “the west” as he described! who is right and who is wrong?
@RuwaydaMustafah: #Obama didn't mention #Gaddafi by name, why? #Libya
@aishes: Maybe Obama refusing to mention #Gaddafi was his way of delegitimizing him? I'm still trying to glean something substantial from his speech.
@TheGaryRuppert: Gaddafi mentioned murdering protesters 17 times in his speech. But Obama thinks they can go to Geneva and have a peace summit? #tcot #p2
@Abdulla_AlAthba: @PhoenixRising4O I'm not after Mr. Obama speech, I wanted free fly-zone in #Libya right away, to make sure #Gaddafi wont bomb his ppl.
@Jim_Gardner: #Obama speech on #Libya didn't mention #Gaddafi by name. Not once. Is he trying to safeguard Americans living in Libya? Could be.
@Afterseven: If Gaddafi's not careful, Obama could write him a very sternly worded letter of rebuke. Framed of course, with an accompanying iPod
@shablibi: To be fair I think that @obama's statement was smart, he distant himself from #Gaddafi and talked simply about #Libya therefore no cause
@RamsayShort: Obama talks crap.He has not mentioned the word Gaddafi once.He is buying time, ignoring the reality.His nation supported Gaddafi.A joker.
@mattklewis: Obama must show leadership. Should call on Gaddafi to immediately step down. Should work with UN to set up a no-fly zone to protect citizens
@Doylech: Obama has finally decided to say something re #gaddafi. Several thousand lives too late #libya
@bengalbabydaddy: But suffering elsewhere is okay. @foxnews: #BreakingNews: Obama Calls Suffering and Bloodshed in Libya ‘Outrageous’ and ‘Unacceptable’

} | cccc_CC-MAIN-2013-20 | A GUIDE TO THE DESIGN OP AIR BUBBLERS FOR MELTING ICE
Simon Ince
Abstract
The use of air bubblers for maintaining ice-free areas in lakes and in the sea has been reported abundantly in the technical literature. This author (1962) reported his observations on two air bubbler installations in the Canadian Arctic to the Eighth International Conference on Coastal Engineering. The results of these investigations were, at that time, still inconclusive. Today, some of the mystery is resolved and it is the author's opinion that the existence of a heat reserve is the answer to the problem. Based on this premise, an attempt is made here to develop some guide lines for the proper utilization of this thermal reserve.
Keywords
air bubbles; melting of ice; ice deterrance

W.M. Jeong, J.W. Chae, W.S. Park, K.T. Jung
Abstract
A series of simultaneous field measurements for long and short-period waves under storm and calm wave conditions were made to understand harbor resonances in a partially enclosed harbor. During storm condition the frequency spectra show peaks of considerable magnitude around the wave period of 1 ~ 5 minutes, which are bounded long waves and their harmonics. They are strongly related with storm waves but longer period (free long) waves are not in the harbor. Numerical tests were also carried out by using the hybrid element model including entrance separation losses in a simple rectangular harbor to validate the model for a mostly constricted entrance case. Further the model was used to simulate the long period oscillation in Muko harbor. Comparisons were made between field data and numerical results to discuss the effect of storm waves on the long period oscillations. Tests demonstrate the effect of input parameters on model results and proper choice of them are stressed.

Majority Rules is Democracy But so Is Dissent Democratic
If you go here, you can find the entire decision but for a short survey, here is okay.
The story? The Chief Justice of the US Supreme Court was in the minority on a question of constitutional validity of a search. What was at issue was the justification the judges used to alter the law, something similar here in Israel in terms of sociall norms, etc.
Excerpts:-
Writing for the majority, Justice David H. Souter said the search was unreasonable, given the vocal objection of the husband, Scott Randolph. True, Justice Souter said, the court had long permitted one party to give consent to a search of shared premises under what is known as the "co-occupant consent rule." But he said that rule should be limited to the context in which it was first applied, the absence of the person who later objected.
The presence of the objecting person changed everything, Justice Souter said, noting that it defied "widely shared social expectations" for someone to come to the door of a dwelling and to cross the threshold at one occupant's invitation if another objected.
"Without some very good reason, no sensible person would go inside under those conditions," he said.
"We have, after all, lived our whole national history with an understanding of the ancient adage that a man's home is his castle," Justice Souter said. "Disputed permission is thus no match for this central value of the Fourth Amendment."
The dissenters, in addition to Chief Justice Roberts, were Justices Antonin Scalia and Clarence Thomas. In his opinion, the chief justice took aim at the majority's description of social custom, as well as its reliance on that description to reshape "a great deal of established Fourth Amendment law."
Every lower federal court to have considered the issue, as well as most state courts, had concluded that one party's consent was sufficient. The Georgia Supreme Court, in its 2004 decision that the justices affirmed, was in the minority, ruling in this case that the evidence of Mr. Randolph's cocaine use was inadmissible.
"The fact is that a wide variety of differing social situations can readily be imagined, giving rise to quite different social expectations," Chief Justice Roberts said. For example, he continued, "a guest who came to celebrate an occupant's birthday, or one who had traveled some distance for a particular reason, might not readily turn away simply because of a roommate's objection."
Noting that "the possible scenarios are limitless," he said, "Such shifting expectations are not a promising foundation on which to ground a constitutional rule, particularly because the majority has no support for its basic assumption — that an invited guest encountering two disagreeing co-occupants would flee — beyond a hunch about how people would typically act in an atypical situation."
The majority missed the point, the chief justice said; the fact is that someone choosing to share space has also, already, chosen to share privacy.
"Our common social expectations may well be that the other person will not, in turn, share what we have shared with them with another — including the police," he said, "but that is the risk we take in sharing."
In a concluding paragraph of his dissent, he said: "The majority reminds us, in high tones, that a man's home is his castle, but even under the majority's rule, it is not his castle if he happens to be absent, asleep in the keep or otherwise engaged when the constable arrives at the gate. Then it is his co-owner's castle."
In Israel, I can't recall the judges voting that way. In fact, they usually kowtow to Professor Aharon Barak's activism and liberalism.

Throughout the history of commercial life nobody has ever quite liked the commission man. His function is too vague, his presence always seems one too many, his profit looks too easy, and even when you admit that he has a necessary function, you feel that this function is, as it were, a personification of something that in an ethical society would not need to exist. If people could deal with one another honestly, they would not need agents. Chandler, Raymond

A healthy self-love means we have no compulsion to justify to ourselves or others why we take vacations, why we sleep late, why we buy new shoes, why we spoil ourselves from time to time. We feel comfortable doing things which add quality and beauty to life. Matthews, Andrew

Dafydd,
I think your experience shows how in the future governments will have to start to get involved with the legislation relating to robotics.
In Fukokua in Japan, they have already started with these laws to allow future robots to roam freely in the streets and move about without human interference.
Tim B.

"Viva Mars Vegas" is the one hundred and twenty-sixth episode of Futurama, the twelfth of the seventh production season and the ninth broadcast season. The Planet Express crew stages a casino heist to recover stolen property from the Robot Mafia.
Contents
[edit] Plot
[edit] Act I: "Category Five Sucker Now Arriving."
The Robot Mafia steals some money from a delivery company. Meanwhile, the crew decides to go to a casino in Mars Vegas. Zoidberg is excited to go, but Amy tells him not to come because of his poor money managing skills. Dejected, he goes back to his dumpster. Meanwhile, the Robot Mafia is being chased by the police, so they decide to dump their money in Zoidberg's dumpster, where Zoidberg takes it. Zoidberg goes to Mars Vegas, and after a few risky bets, he loses all of the money. When he gets back to the dumpster, he finds it occupied by the Robot Mafia wanting their money back.
[edit] Act II: "Mr. Wong, we have a mafia proposal for you. Your casino...give it to us."
After Zoidberg tells them that he lost all of the money to the casino, they try to kill them, but Zoidberg escapes by triggering his ink defense, which covers him in ink. He goes to the Planet Express building, where Professor Farnsworth accidentally uses a ink remover to make all the ink on Zoidberg invisible. This makes Zoidberg invisible as well, and then the Robot Mafia break into the PE bulding and look for Zoidberg. Because Zoidberg is invisible, he cannot be found by them. The mafia decide to get their money back by taking over the casino. In the process, they take away all of Leo and Inez Wong's property, including their mansion, which reduces them to living in the area they set aside for their employees. However, Amy comes up with a plan to get the money back, with a little help from Zoidberg.
[edit] Act III: "He STINKS like the inside of a Tauntaun."
Using a smelly shrimp cart to hide Zoidberg's stench, the crew goes upstairs to the area with the safe. Leela, Amy, and Fry, who are pushing the cart, pretend to have a broken wheel so that they have a reason to stay up there, while Professor Farnsworth, Hermes, and Bender distract Donbot to keep him from closing the safe door prematurely. Meanwhile, Zoidberg gets into the safe and eats all of the money, except a few bills he coughs up, making it just as invisible as he is. He also eats a black box. However, after eating all of this, he becomes too heavy to move, so the Professor, Hermes, and Farnsworth have to carry him out until they can get him on the shrimp cart. They had intended to escape through the roof, but Zoidberg's weight made the elevator fall to the first floor, forcing them to escape through the main lobby. Zoidberg starts coughing up money as they go. Despite this, they almost make it to the exit, until a blind guard, Blind Joe catches them. He tries to force them to give him the money, but Amy tries to make a deal with him. Because the guard is a Native Martian, he doesn't like making deals with the Wong Family. Amy says that this is because he doesn't know about the original deal, which only gave the Wong family the right to occupy the land for 100 years before they gave the land back to the Native Martians. Because of this, the Native Martians own the casino, and they kick the Robot Mafia out. Fortunately for the Wong family, the Native Martians give back the Wong's mansion and their other casino. Professor Farnsworth tells Zoidberg that he'll become visible again as soon as he takes a bath, and he goes with Amy to the other casino.
[edit] Production
On 29 February 2012, CGEF revealed the episode's title, its writer to be Josh Weinstein and its director to be Frank Marino.[1][2] On 10 July, MSN TV updated their Futurama episode guide, revealing the episode's plot and air date.[3] The same day, Zap2it released a TV listing of Futurama which showed the same information about the episode, with slight variation from the plot published by MSN.[4]
On 12 July, following the broadcast of the episode "Zapp Dingbat", the public were given the opportunity to participate in a live chat with the Futurama cast and crew. Several clips of "Viva Mars Vegas" during the live stream.[5]
[edit] Additional information
[edit] Continuity
[edit] Allusions
• The episode's title is a reference to the 1964 Elvis Presley film Viva Las Vegas.
• The song played through the montage of Zoidberg spending his cash and sung by Zoidberg himself at the end of the episode is a parody of the song Big Spender from 1966 musical Sweet Charity.
• The Binks Armored Express truck at the beginning of the episode is a reference to the Star Wars character Jar Jar Binks from Episode I: The Phantom Menace, and the Brink's armored trucks. The truck is also piloted by two aliens that bear a striking resemblance to the Gungans, Jar Jar's species, and they also speak like him.
• The Donbot refers to the stolen money as "De Niros", a play on "denaros" and Robert De Niro whom the Donbot is based upon. Of De Niro's various films is Casino which involves mob connections in Vegas.
• The Professor says "Dude, where's my ship?", in reference to the 2000 stoner comedy film Dude, Where's My Car?
• The ball that the croupier uses in the roulette game flaps its "wings" and flies around the roulette wheel, making it very similar to a Golden Snitch from Harry Potter. It does not behave this way during the final spin that results in Zoidberg losing, though.
• The plot of an orchestrated casino heist has been the subject of many films including Ocean's Eleven.
• The deal made by Sir Reginald Wong with the Native Martians was supposed to last as long as the deal the deal the British made with the Chinese to gain control of Hong Kong.
• Wong Island is a parody of the Las Vegas hotel and casino Treasure Island. Its name may also be a reference to New York's Long Island.
[edit] Trivia
The opening caption of the live recreation of the opening sequence.
• When the vault scans the Donbot's finger, it identifies him as Don "Smith".
• The title sequence for this episode is a live-action recreation, which was also used to promote the new season through ads on Comedy Central. It is also the second major alternate one-off title sequence since Into the Wild Green Yonder.
• Zoidberg reads a newspaper called "The Daily Bum Blanket".
• This is the second episode (in production order) of season 7 to be aired out of order, as the broadcast order of both this episode and "31st Century Fox" were swapped.
• It is confirmed in the commentaries that this swap was requested by Comedy Central as they wanted to advertise Patrick Stewart being in the season finale (which they subsequently did not).
• The Professor says that he is a young internet billionaire, in reference to Mark Zuckerberg, who created Facebook whilst at University.
• Arriving at the parking lot of the casino, Planet Express Ship crushes what appears to be Mars Curiosity rover, although it appears larger than the real life robot compared to the size of the ship.
[edit] Quotes
Zoidberg: Look out, penny slots, I've got a system! It's to put all my money in you! [He laughs to himself.]
Zoidberg: [He sighs then puts his claws together and begins to pray.] God, it's Zoidberg. I hate to bother you, but- [A huge bag full of money lands directly in front of him, he looks inside.] Okay, okay, I'll shut up!
Joey Mousepad: [He bangs on the door.] It's no use, Zoidberg! We're like 85% sure you're in there!
Professor: My God! He was so saturated with ink that his entire body structure was polarized!
Zoidberg: You mean I'm invisible?
Professor: No, no, no, not in any sense of the word. But essentially, yes, entirely.
[As Zoidberg risks the $8 million on a single game of roulette.]
Amy: Zoidberg, what are you doing?
Zoidberg: I don't know. I think it's called "roulette".
[edit] Goofs
• Native martians are seen here, but they all left Mars in "Where the Buggalo Roam".
• That doesn't mean some few would not return possibly out of a sense of attachment to their ancestral lands.
• Zoidberg spends a lot of money before he gets to the table, so he couldn't have had eight million left. Because of this, he shouldn't have been able to buy eight chips, each worth a million dollars.
• At the beginning of the episode Donbot said "It's over eight million bucks". So Zoidberg could only spend the "over" part.
• If the Wongs had two casinos, then why not just go there when the mafia take their first casino and their house? Furthermore, if this is New Mars Vegas as in Into the Wild Green Yonder, wouldn't the Wong family have many business holdings over the entire planet?
• It might have been possible that most of the building were damage during the Farewell to arms' incident with only those two casino being operational at the time.
• None of the mafia, or the native martians seemed to question, why the old shrimp carriers, and all those people turned up (the crew in disguise) in the money counting room, despite the fact its supposed to be the most secure area.
• This may have been done intentionally as a joke.
• The deal between the native martians and the Wongs here is different to the deal mentioned in "Where the Buggalo Roam".
• The deal only involved paying for the land, there was no mention of whether Sir Reginald was purchasing or leasing it. Thus his compassionate intentions to give back the land must have been a lost detail that only Amy was familiar with.
• Amy also might have told Blind Joe something that he'd want to hear to make him side with her family.
• Zoidberg doesn't eat the two 100 dollar bills that fall out of his mouth.
• The ink on Zoidberg's mouth is wiped off, exposing it. When Amy escorts Zoidberg to Wong Island, the ink on Zoidberg's mouth has returned, as the pink of his skin would have been able to see from the back of him.
• It's possible that it doesn't show because the ink on the back of his head covers it, which would be why we can't see inside of him.
• The Professor says that the ink will wash off when Zoidberg takes a bath. But in the bath scene, the ink doesn't wash off.
• As a robot, Bender doesn't possess a scent, so how could Blind Joe smell, he was stealing money?
• Bender would have a strong scent of alcohol and tobacco.
• In Godfellas the Professor notes that Bender does have an odor, however mild.
• Why didn't the ink come off on the money or Amy when Zoidberg touched them?
• The ink would have dried by then.
• When Zoidberg places his third bet on 34 red, he pushes all the chips away to his left onto 34 on the roulette board, but while the wheel is spinning the chips are right in front of him again. His sardinie has also filled back up after he loses, although it could be a refilling glass like the ones seen in "That Darn Katz!".
• Zoidberg's eyes weren't covered with ink, neither was the inside of his mouth. So, while he is invisible, you should have been able to see his eyes and see his tongue when he speaks.

Hi Fiona - I am extremely interested in the integration of sustainability into the curriculum and am embarking on research in this area. In particular I will be looking at current practice/s and models within the NZ fashion industry and the implications for fashion education & educators. Havent had the chance to set up my blog yet but can keep u posted on progress - this is brand new research and I am a new researcher with limited hours so it will be slow progress. Will post this on ur blog too. Cheers Tracy

Abstract
Background
The MAL2 gene, encoding a four-transmembrane protein of the MAL family, is amplified and overexpressed in breast and other cancers, yet the significance of this is unknown. MAL-like proteins have trafficking functions, but their molecular roles are largely obscure, partly due to a lack of known binding partners.
Methods
Yeast two-hybrid screening of a breast carcinoma cDNA expression library was performed using a full-length MAL2 bait, and subsequent deletion mapping experiments were performed. MAL2 interactions were confirmed by co-immunoprecipitation analyses and confocal microscopy was employed to compare protein sub-cellular distributions. Sucrose density gradient centrifugation of membranes extracted in cold Triton X-100 was employed to compare protein distributions between Triton X-100-soluble and -insoluble fractions.
Results
The tumor-associated protein mucin 1 (MUC1) was identified as a potential MAL2 partner, with MAL2/MUC1 interactions being confirmed in myc-tagged MAL2-expressing MCF-10A cells using co-immunoprecipitation assays. Deletion mapping experiments demonstrated a requirement for the first MAL2 transmembrane domain for MUC1 binding, whereas the MAL2 N-terminal domain was required to bind D52-like proteins. Confocal microscopy identified cytoplasmic co-localisation of MUC1 and MAL2 in breast cell lines, and centrifugation of cell lysates to equilibrium in sucrose density gradients demonstrated that MAL2 and MUC1 proteins were co-distributed between Triton X-100-soluble and -insoluble fractions. However co-immunoprecipitation analyses detected MAL2/MUC1 interactions in Triton X-100-soluble fractions only. Myc-MAL2 expression in MCF-10A cells was associated with both increased MUC1 detection within Triton X-100-soluble and -insoluble fractions, and increased MUC1 detection at the cell surface.
Conclusion
These results identify MUC1 as a novel MAL2 partner, and suggest a role for MAL2 in regulating MUC1 expression and/or localisation.
Background
Human MAL2, a 19 kDa protein with four transmembrane (TM) domains [1,2] is a member of the MAL protein family. The founding member MAL [3] resides in lipid rafts [4,5] and is required in apical vesicle transport [6-9]. The MAL family also includes less characterised members, including BENE, which is also a raft-associated integral membrane protein [10], plasmolipin, a 20 kDa proteolipid expressed in compact myelin and epithelial cells [11] and chemokine-like factor superfamily 8 (CKLFSF8), a novel regulator of EGF-induced signalling [12]. MAL2 was identified as a partner for tumor protein D52-like proteins through yeast two-hybrid (Y2H) expression screening of a human breast carcinoma library [1]. The MAL2 protein is now known to be expressed in many epithelial cell types, as well as peripheral neurons, mast cells and dendritic cells [13]. In HepG2 hepatoma cells, MAL2 resides exclusively within lipid rafts, and represents an essential component for indirect basolateral-to-apical transcytosis [2], where it shows a highly dynamic subcellular localisation [14]. MAL2 has also been reported to be distributed in both lipid raft and non-raft fractions in primary thyrocytes [15] and PC-3 prostate carcinoma cells [16], predicting additional, uncharacterised cellular functions for MAL2 outside lipid rafts.
The initial identification of MAL2 suggested its overexpression in breast cancer [1], which is supported by the MAL2 gene being found at chromosome 8q24, which is frequently gained in breast and other cancers [17]. Several studies have now identified MAL2 amplification and/or overexpression in breast cancer [18-22]. Overexpression of MAL2 has also been reported in other cancers, including primary ovarian carcinoma [23,24] and ascites [25], and pancreatic carcinoma [26], where MAL2 has since been employed as a discriminator of pancreatic carcinoma versus chronic pancreatitis [27]. Expression profiling has also indicated MAL2 overexpression in malignant pleural mesothelioma of the epithelial type [28], and in head and neck squamous cell carcinoma [29]. Immunohistochemical analyses first revealed differential MAL2 expression in renal carcinomas [15], with this being recently confirmed in chromophobe renal cell carcinoma versus oncocytoma [30].
Despite numerous reports of MAL2 overexpression in breast cancer, little is known about how increased MAL2 expression may provide an advantage to cancer cells. While MAL2 cellular localisation and function have been explored in previous studies [2,14,15], the only known MAL2 partners are members of the D52-like protein family [1]. Interactions between MAL2 and both D52 and D53 have since been identified in a large scale Y2H analysis [31], which supports further use of the Y2H system to analyse MAL2 function. We therefore carried out a Y2H screening of a breast carcinoma cDNA expression library [1,32] to identify novel MAL2 binding partners. One protein thus identified was mucin 1 (MUC1), a transmembrane protein expressed on the apical surface of epithelial cells [33] and overexpressed in multiple cancers [34], in part through MUC1 gene amplification [35]. Like other mucins, MUC1 protects and lubricates normal glandular epithelia, whereas MUC1 overexpression in cancer alters many cellular properties, including intercellular adhesion and immune recognition [33,34]. As MUC1 therefore represented a candidate MAL2 partner of particular interest, subsequent experiments were performed to confirm MAL2/MUC1 interactions, and examine their significance in breast epithelial and cancer cells. As we will describe, this work identifies a MAL2 as a cytoplasmic MUC1 partner which binds MUC1 in non-lipid raft fractions, and may regulate MUC1 expression and/or subcellular distribution.
Methods
Plasmid constructs
Bait proteins for use in the Y2H system were expressed from the pAS2-1 vector (Clontech, Mountain View, California, USA), and prey proteins were expressed from the pACT2 (Clontech) or pAD-GAL4 (Stratagene, La Jolla, CA, USA) vectors. The pAS2-1MAL2 bait construct was obtained by subcloning an EcoRI-XhoI fragment, representing the entire MAL2 cDNA insert, into the EcoRI and SalI sites of pAS2-1 vector. For the pAS2-1MAL and pACT2MAL constructs, a MAL cDNA insert was amplified by PCR amplification to introduce a 5' NcoI site, and a 3' XhoI site downstream of the stop codon, which was then subcloned into the corresponding or compatible sites in pAS2-1 and pACT2. Constructs including truncated versions of the MAL2 coding region were amplified by the polymerase chain reaction (PCR) using specific primers (Table 1). For the pAS2-1MAL2ΔN and pACT2 MAL2ΔN constructs, primers introduced a 5' NcoI site, and a 3' XhoI site downstream of the stop codon. For the pAS2-1MAL2ΔNTM1, pAS2-1MAL2ΔNTM12, pAS2-1MAL2ΔNTM123 and pAS2-1MAL2ΔNTM1234 constructs, primers introduced a 5' EcoRI site, and a 3' XhoI site downstream of the stop codon. All subcloned constructs were verified by DNA sequencing, with PCR-generated inserts being fully sequenced on one DNA strand. The pCR3.1/Myc-MAL2 expression construct has been previously described [2]. All constructs encoding D52-like fusion proteins, and the human breast carcinoma cDNA library constructed in the HybriZAP vector (Stratagene) have been previously described [1,32].

Yeast two-hybrid system and screening
Yeast cultures of the Saccharomyces cerevisiae Hf7c strain were grown at 30°C in standard liquid or solid media, based upon either rich YPD media (2% bacto-peptone, 1% yeast extract, 2% dextrose), or minimal SD medium (0.67% yeast nitrogen base without amino acids, 2% dextrose, with appropriate amino acid supplements) for expression library screening and direct interaction testing. For cDNA library expression screening, bait (pAS2-1MAL2) and human breast carcinoma pAD-GAL4 library plasmids were transfected simultaneously into Hf7c cells. Subsequent screening and the recovery of plasmid DNA from yeast cells were carried out as described [32]. For the direct testing of interactions, paired baits (pAS2-1 constructs) and preys (pACT2 or pAD-GAL4 constructs) were transfected into Hf7c cells as described [32]. Interactions between baits and preys were assessed by qualitatively determining HIS3 reporter gene activity [1].
Antibodies
The BC2 (an anti-MUC1 VNTR epitope mouse IgG1 monoclonal) and FITC-BC2 antibodies have been previously described [36]. Rabbit polyclonal c-Myc (A-14) and CAV1 antibodies were purchased from Santa Cruz Biotechnology (Santa Cruz, CA, USA) and BD Biosciences (BD Biosciences, San Jose, CA, USA), respectively. Affinity-purified D52 rabbit polyclonal antibody has been described previously [37]. Peroxidase-conjugated donkey anti-rabbit and anti-mouse, FITC-conjugated donkey anti-mouse and CY3-conjugated donkey anti-rabbit secondary antibodies were purchased from Jackson ImmunoResearch, Inc (West Grove, PA, USA).
Preparation and affinity purification of polyclonal MAL2 antisera
For the production of sheep antisera, one sheep was injected subcutaneously with 2 mg coupled MAL2 C165-P176 peptide antigen on 2 occasions, spaced by 3 weeks. For the production of rabbit antisera, two rabbits were injected subcutaneously with 0.5 mg coupled N13-V24 and C165-P176 MAL2 peptide antigens on 2 occasions, spaced by 2 weeks. Antisera were affinity-purified using relevant MAL2 peptides as previously described [37].
Human breast cell lines
The MDA-MB-435 (a kind gift from Dr Janet Price, MD Anderson Cancer Centre, Houston, TX), MDA-MB-453, SK-BR-3 and MCF-7 breast cancer cells were cultured as described in the American Type Culture Collection Catalogue. MCF-10A cells are described in the American Type Culture Collection Catalogue and were cultured as described [38].
Derivation of stably-transfected cell lines
The Myc-tagged MAL2 expression construct was stably transfected into MCF-10A cells. Cells were seeded at approximately 60% confluence in 100 mm dishes and transfected 18 h later with 20 μg plasmid DNA using LipofectAMINE 2000 Reagent (Life Technologies, Inc., Gaithersburg, MD, USA), according to the manufacturer's instructions. After 24 h, G418 was added to a concentration of 1 mg/ml. Media were replenished every 2–3 days and a G418-resistant mixed population was selected 14 days post-transfection. MDA-MB-435 and MDA-MB-453 breast cancer cells were transfected by electroporation with a MUC1 cDNA containing 22 VNTR repeats in the pcDNA3 vector (Invitrogen) or the vector alone. Stable G418 resistant clones were isolated and MUC1 expression determined by flow cytometry.
Preparation of total protein extracts and Western blot analyses
Cells were harvested in cold PBS, pelleted and washed twice in cold PBS. Total cell protein extracts were prepared by resuspending the pellet in SDS extraction buffer (125 mM Tris-HCl pH 6.8, 3% SDS, 5% 2-mercaptoethanol, 1 mM PMSF, and protease inhibitors [Roche, Basel, Switzerland]), which were then briefly sonicated. Samples were resolved using SDS-PAGE on 12.5% polyacrylamide gels, and electrotransferred to nitrocellulose filters (Millipore, Billerica, MA, USA). Protein loading was analysed using Ponceau S staining, and filters were blocked overnight at 4°C in 5% skim milk powder in TBS. Membranes were washed twice with TBS and incubated with either affinity-purified rabbit polyclonal MAL2 antisera (1/100), affinity-purified rabbit polyclonal D52 antisera (1/100), BC2 (1/100) or CAV1 antibody (1/2000) in 0.1% Tween 20 in TBS, for 2 h. Membranes were washed 3 times in 0.1% Tween 20 in TBS, and then incubated with horseradish peroxidase-conjugated donkey anti-rabbit or donkey anti-mouse secondary antibody (Jackson ImmunoResearch, Inc) (1/5000) for 2 h. Blots were washed 4 times with 0.1% Tween 20 in TBS, followed by 2 washes in TBS and antigen-antibody complexes were visualised by Western lightning chemiluminescent reagent (Perkin Elmer, Waltham, Massachusetts, USA).
Co-immunoprecipitation analyses
MCF-10A cells were grown to 80% confluence in 100 mm dishes and washed with cold PBS. For each co-immunoprecipitation, proteins were extracted by scraping cells from 6 dishes into 0.15 ml lysis buffer per dish. For co-immunoprecipitation of MAL2 and D52 proteins, 10 mM Tris with 1 mg/ml Saponin (Sigma-Aldrich, St. Louis, MO, USA) was employed as a lysis buffer [39]. For co-immunoprecipitation of MAL2 and MUC1 proteins, SDS lysis buffer (125 mM Tris-HCl pH 6.8, 3% SDS, 5% 2-mercaptoethanol, 1 mM PMSF, and protease inhibitors (Roche) was employed. Protein A-Sepharose beads (Sigma-Aldrich) plus rabbit MAL2 antisera (1/50), either alone or with 1 μg/ml synthetic peptides N13-V24 and C165-P176, or protein G-agarose beads (Sigma-Aldrich) plus BC2 (1/50) were added to cell lysates and incubated on a rotary mixer at 4°C for 16 h. Beads were washed 4 times with 1 ml lysis buffer, followed by a final wash with PBS. Eluted proteins (15 μl) were separated using SDS-PAGE on 12.5% polyacrylamide gels and electrotransferred to nitrocellulose filters (Millipore) for Western blot analyses, as above.
Immunofluorescent labelling of breast cell lines
Cell lines were cultured to near confluence, and harvested by trypsinisation. Cells were diluted 3- to 10-fold and cultured overnight on glass coverslips. For immunofluorescent staining, cells were washed twice with PBS, and fixed in 4% paraformaldehyde supplemented with 0.1% saponin for 20 min at RT. Cells were washed twice with PBS, and incubated at RT for 2 h with affinity-purified rabbit MAL2 (1/50), D52 (1/100) antisera or mouse BC2-FITC (40 μg/ml), in 0.1% bovine serum albumin (BSA) in PBS. Primary antibody was omitted in control incubations. Cells were washed twice with PBS and incubated with a CY3-conjugated donkey anti-rabbit secondary antibody (1/500) (Jackson ImmunoResearch) in 0.1% BSA in PBS, for 1 h in the dark. Cells were washed again and DNA was counterstained with 10 nM DAPI (Sigma-Aldrich). Following 2 washes in PBS, cells were mounted in DAPCO (Sigma-Aldrich) prepared according to the manufacturer's instructions. Images were taken using a TCS SP2 Laser Scanning Confocal microscope (Leica Technologies, Wetzlar, Germany), using a 63× oil-immersion objective and a 4× zoom factor.
Membrane fractionation analyses
Triton X-100 soluble and insoluble fractions were prepared essentially as described [40]. Cells grown in 4 × 100 mm dishes were treated with 20 mM methyl β-cyclodextrin (MβCD) at 37°C for 30 min. Cells were then rinsed with PBS and lysed for 20 min in 1 ml 25 mM Tris-HCl pH 7.5, 150 mM NaCl, 5 mM EDTA, 1% Triton X-100 at 4°C. The lysate was brought to 40% sucrose in a final volume of 4 ml, placed at the bottom of a 12 ml tube, and then layered with 6 ml 30% sucrose followed by 2 ml 5% sucrose, made in the same buffer without Triton X-100. Gradients were centrifuged for 22 h at 36,000 rpm at 4°C in a Beckman SW41 rotor. Fractions of 1 ml were harvested from the top of the tube and aliquots were subjected to Western blot analyses.
Results
Yeast two-hybrid screening identifies MUC1 as a putative MAL2 partner
To identify MAL2 partners expressed in breast cancer tissue, a Y2H screen of a breast carcinoma cDNA expression library [1,32] was performed with a full-length MAL2 bait. Screening 5,000,000 cfu in Hf7c cells identified 72 Hf7c colonies that remained His+ on restreaking on solid SD/-Leu-Trp-His media. Sequencing the corresponding cDNA inserts identified 6 novel candidate MAL2 binding partners, of which MUC1 was most frequently isolated. DNA sequencing indicated that all 7 MUC1 prey constructs [preys #1–#7] encoded N-terminally truncated MUC1 proteins, which commonly included the SEA module, the TM domain and the cytoplasmic tail (Figure 1a). Testing whether MUC1 (prey#1, Figure 1a) could reproducibly bind MAL2 and/or the related protein MAL showed that MUC1 could bind both MAL2 and MAL baits in the Y2H system (Figure 1b). In contrast, D52-like baits bound MAL2 prey as previously reported [1], but not MAL (Figure 1b). Since MAL and MAL2 sequences differ in their N-terminal regions [1] and a full-length MAL2 prey was originally isolated using a D54 bait [1], the MAL2 N-terminal domain (M1-T34) was hypothesised to represent the interaction interface with D52-like proteins. Deleting this region abolished interactions with all D52-like proteins tested, but did not affect interactions with MUC1 (Figure 1b), suggesting that MUC1 and D52-like proteins bind discrete regions of MAL2.
Figure 1. (a) Schematic diagram of MUC1 preys (prey#1-prey#7) isolated during Y2H screen. All prey proteins were predicted to include the SEA module, the transmembrane domain (TM) and the cytoplasmic tail (CT). The length of the extracellular tandem repeat is not shown to scale in full-length MUC1. (b) Deleting the MAL2 N-terminus does not affect its binding to MUC1 but abrogates its interaction with D52-like proteins. Interactions were tested between MAL, MAL2 or MAL2ΔN, and MUC1 (prey#1) or D52-like proteins in Hf7c cells using the Y2H system. (-) indicates no detectable growth of co-transformants on triple drop-out plates after 6–8 days at 30°C, (++) indicates growth after 3–4 days and (+++) indicates growth after 1–2 days. Identical results were obtained for all 3 D52-like baits, which were grouped together in a single column. Results shown are representative of those obtained in 3 independent experiments.
Derivation of polyclonal antisera which specifically recognise MAL2 protein
To confirm MAL2/MUC1 interactions in other systems, MAL2 antisera were generated in two species. Polyclonal antisera were generated in sheep and targeted the MAL2 C-terminus (C165-P176). An N-terminal MAL2 peptide (N13-V24) [2] as well as the C-terminus (C165-P176) were also targeted for polyclonal antibody production in rabbit [1]. Both peptide sequences are poorly conserved in other MAL-like proteins [1]. Rabbit MAL2 antisera were employed in Western blot analyses of total protein extracts from a panel of human breast carcinoma cell lines, as well as MCF-10A breast epithelial cells. A MAL2 species of the predicted molecular weight of 19 kDa was detected in extracts from MDA-MB-435 and MDA-MB-453 cell lines stably transfected with a MUC1 expression vector (M) or the corresponding vector (V), and from MCF-10A, SK-BR-3 and MCF-7 cells. This is in agreement with previous detection of the 19 kDa MAL2 species in other cell types [2,13]. Higher molecular weight MAL2 species were also detected (Figure 2), and are likely to represent glycosylated MAL2 forms [1,2,15].
Figure 2. MAL2 antisera detect glycosylated and non-glycosylated MAL2 forms in human breast cell lines, as indicated above the top panel. Total protein extracts were subjected to Western blot analysis using rabbit MAL2, D52 and MUC1 antisera, as indicated to the left of each panel. Sizes of detected proteins are indicated at the right. Results shown are representative of at least 3 independent experiments.
Co-immunoprecipitation of MUC1 and MAL2 from MCF-10A/Myc-MAL2 cells
Co-immunoprecipitation analyses were used to confirm interactions between MAL2 and MUC1 proteins in MCF-10A breast epithelial cells, stably-transfected with a Myc-tagged MAL2 construct (MCF-10A/Myc-MAL2 cells). Protein extracts were immunoprecipitated with either MUC1, c-Myc or MAL2 antisera, the latter in the absence or presence of MAL2 peptides. Immunoprecipitated proteins were then subjected to Western blot analyses with MUC1, MAL2, c-Myc and D52 antisera. These analyses demonstrated that MUC1 monoclonal antibody immunoprecipitated MUC1 and co-immunoprecipitated MAL2, as demonstrated by both MAL2 and c-Myc antisera, and that c-Myc and MAL2 antisera immunoprecipitated MAL2 and co-immunoprecipitated MUC1 (Figure 3). Interactions between MUC1 and MAL2 proteins were also reproducibly demonstrated in MCF-7 cells and MUC1-transfected MDA-MB-435 cells (data not shown). As expected, D52 co-immunoprecipitated with MAL2 and c-Myc antisera, and interestingly with MUC1 as well (Figure 3), suggesting that MUC1 and D52 may form a multi-molecular complex with MAL2. Inclusion of MAL2 peptide abolished immunoprecipitation of MAL2 and co-immunoprecipitation of both MUC1 and D52 (Figure 3).
Figure 3. Co-immunoprecipitation analyses verifying interactions between MAL2 and MUC1. Total cell lysate from MCF-10A/Myc-MAL2 cells was immunoprecipitated with MUC1, c-Myc, or rabbit MAL2 antisera, either alone or with MAL2 peptides, as indicated above the top panel. Total cell lysate and immunoprecipitates were separated by SDS-PAGE and subjected to Western blot analyses with antisera against MUC1, MAL2, c-Myc and D52, as indicated at the left. Sizes of detected proteins are indicated at the right. Results shown are representative of at least 3 independent experiments.
Mapping the MAL2 region required for MUC1 binding
The differential binding of D52-like proteins and MUC1 to MAL2ΔN and MAL (Figure 1b) suggested that D52 and MUC1 bind different MAL2 domains. To map the MUC1 binding domain in MAL2, additional N-terminal MAL2 deletion mutants were constructed, to serially delete the four MAL2 TM domains (Figure 4a). The TM domains were specifically targeted as the MUC1 TM domain was encoded by all prey constructs isolated (Figure 1a). Interactions were detected between MUC1 prey and MAL2ΔN bait, but not MAL2 bait additionally lacking the first TM domain (MAL2ΔNTM1). Another putative MAL2 partner identified through Y2H screening showed detectable interactions with MAL2ΔNTM1, indicating that the lack of MUC1 binding to MAL2ΔNTM1 was not artifactual (S. Fanayan, unpublished results). These analyses therefore indicate that the first MAL2 TM domain (Y35-S56) is required for MUC1 binding (Figure 4b). Similar deletion mapping experiments involving MUC1 indicated that the minimal MAL2 binding region was contained within the shortest MUC1 prey (prey #7) identified through yeast two-hybrid screening (Figure 1a) (S. Fanayan, unpublished results).

(b) Results of testing interactions between full-length and deleted MAL2 bait proteins and MUC1 (prey#1) prey protein in Hf7c cells using the Y2H system. (-) indicates no detectable growth of co-transformants on triple drop-out plates after 6–8 days incubation at 30°C while (++) indicates growth after 3–4 days. Results shown are representative of those obtained in 3 independent experiments.
MAL2 and MUC1 co-localise in the cytoplasm of breast carcinoma cells
The intracellular localisation of MAL2 in breast cancer cells was determined using indirect immunofluorescence and confocal microscopy, and compared with that of MUC1. As shown in Figure 5, SK-BR-3 and MUC1-overexpressing MDA-MB-435(M) cells showed punctate distributions of MAL2 and MUC1 throughout the cell cytoplasm, with partial co-localisation. In MCF-7 and MDA-MB-453(M) cells, MAL2 was similarly detected throughout the cytoplasm, while MUC1 was concentrated towards the cell periphery, and showed only partial co-localisation with MAL2. These results indicate that MAL2 and MUC1 co-localise within the cytoplasm, regardless of the predominant site of MUC1 localisation. Furthermore, MUC1 overexpression in MDA-MB-435 and MDA-MB-453 cells did not alter MAL2 distribution in these cells (Figure 5).
Figure 5. MAL2 and MUC1 co-localise in the cytoplasm of breast carcinoma cell lines. Indirect immunofluorescent analyses were carried out using the cell lines indicated to the left of each row, and MUC1 and sheep MAL2 antisera. MUC1 antibody was identified as green color using a FITC-conjugated secondary antibody (left column) and MAL2 antisera was identified as red color using a Cy3-conjugated secondary antibody (middle column). Overlap between MUC1 and MAL2 proteins is shown as yellow in merged images (right column). Results shown represent those obtained from 3–4 independent experiments.
MAL2 and MUC1 are present in lipid raft fractions in human breast carcinoma cells
MAL2 has consistently been found in lipid raft-containing membrane fractions in hepatoma HepG2 cells [2,14] as well as in human thyroid epithelial cells [15]. We therefore examined the distribution of MAL2 and MUC1 in Triton X-100-soluble and -insoluble fractions from breast carcinoma cell lines. Following centrifugation to equilibrium in sucrose density gradients, the distributions of MAL2 and MUC1 was compared in fractions 2–4, which include Triton X-100-insoluble lipid rafts, and fractions 8–12, which include Triton X-100-soluble cytoplasmic proteins and cell membranes. The distribution of the MAL2 partner D52 was also determined, and compared with that of caveolin-1 (CAV1), a known lipid raft protein [16]. MUC1 was detected in both Triton X-100-soluble and -insoluble fractions when endogenously expressed in SK-BR-3 cells (Figure 6a) and exogenously expressed in MDA-MB-435(M) (Figure 6c) and MDA-MB-453(M) cells (Figure 6e), with MUC1 being predominantly detected in lipid raft fractions in MDA-MB-453(M) cells (Figure 6e). In MDA-MB-435(V) (Figure 6b) and MDA-MB-453(V) cells (Figure 6d), MUC1 was weakly detected in soluble fractions only. MAL2 was detected in both soluble and insoluble fractions in all cell lines examined (Figure 6). The D52 protein was predominantly detected in soluble fractions but weakly detected in insoluble fractions in most cell lines (Figure 6a, b–e). As expected, CAV1 was exclusively detected in lipid raft fractions (Figure 6a and data not shown).
Figure 6. Distribution of MUC1, MAL2 and D52 in membrane fractions from breast cancer cell lines. (a) SK-BR-3, (b) MDA-MB-435(V) (c) MDA-MB-435(M) (d) MDA-MB-453(V) and (e) MDA-MB-453(M) cells were extracted with 1% Triton X-100 at 4°C, and subjected to centrifugation to equilibrium in sucrose density gradients. Twelve 1 ml fractions (Fr, shown above each top panel) were collected from the top of the gradient and 15 μl aliquots from each were subjected to SDS-PAGE and Western blot analysis with antibodies against MUC1, MAL2 and D52, as indicated to the left of each panel. SK-BR-3 fractions (a) were also immunoblotted with CAV1 antibody. In all panels, vertical lines between fractions 8 and 9 distinguish samples loaded on different gels. Sizes of detected proteins are indicated at the right. Results shown represent those obtained from 2–3 independent experiments.
The effect of cholesterol depletion on MUC1 and MAL2 distributions was examined by treating SK-BR-3 and MDA-MB-435(M) cell lines with MβCD. In SK-BR-3 cells, MβCD treatment rendered MUC1, MAL2 and CAV1 virtually undetectable in fractions 2–4 (Figure 7). The apparent disappearance of CAV1 from SK-BR-3 fractions after MβCD treatment is consistent with CAV1 expression being reported as undetectable in whole SK-BR-3 cell extracts [41,42]. In MDA-MB-435(M) cells, MβCD treatment reduced MUC1, MAL2 and CAV1 detection in the same fractions, which was accompanied by increased detection in Triton X-100-soluble fractions (Figure 7), further supporting co-distribution of MUC1 and MAL2 within lipid rafts. We then carried out (co)-immunoprecipitations of MUC1 and MAL2 from pooled soluble and insoluble membrane fractions from MCF-10A/Myc-MAL2 cells. Both MAL2 and MUC1 were detected in insoluble fractions (Figure 8a), yet MAL2 antisera co-immunoprecipitated MUC1 from pooled soluble fractions only (Figure 8b). The ability of MAL2 antisera to co-immunoprecipitate MUC1 from fractions 5–8 despite low MUC1 concentrations supports an association between MAL2 and MUC1 in Triton X-100 soluble fractions.
Figure 7. Effect of MβCD treatment on MUC1 and MAL2 distribution in lipid raft fractions. SK-BR-3 and MDA-MB-435(M) cells were treated (+Mβ), or not (-Mβ), with 20 mM MβCD, extracted with 1% Triton X-100 at 4°C, and subjected to sucrose gradient centrifugation. Twelve fractions of 1 ml (Fr, as shown above each top panel) were collected and 15 μl aliquots were subjected to SDS-PAGE and Western blot analysis with antibodies to MUC1, MAL2 or CAV1, as indicated at the left, with sizes of detected proteins indicated at the right. In all panels, vertical lines between fractions 8 and 9 distinguish samples loaded on different gels. In fractions 2–4, MUC1, MAL2 and CAV1 were not detected in SK-BR-3 cells, or were significantly reduced in MDA-MB-435 [M] cells following MβCD treatment. Results shown represent those obtained from 3 independent experiments.

Antisera employed in Western blot analyses are shown at the left, and sizes of detected proteins are shown at the right. (a) Fractions (Fr, as shown above the top panel) of 1 ml were collected, and aliquots from each were subjected to SDS-PAGE and Western blot analysis with MUC1 and MAL2 antisera. Vertical lines between fractions 8 and 9 distinguish samples loaded on different gels. (b) Pooled fractions (fractions 1–4, which include lipid rafts, fractions 5–8 and fractions 9–12) were immunoprecipitated with MUC1 or MAL2 antisera either alone or with MAL2 peptides (+Pep), as shown at the top of the panel. Immunoprecipitates were separated by SDS-PAGE and subjected to Western blot analysis with MUC1 monoclonal antibody. Results shown represent those obtained from 3 independent experiments.
Increased MAL2 expression leads to increased cell surface expression of MUC1
Interactions between MUC1 and MAL2, together with previous data showing MAL2 involvement in basolateral-to-apical transport [2] suggested a role for MAL2 in localising MUC1 to the cell surface. The effect of ectopic Myc-MAL2 expression on MUC1 subcellular localisation was therefore compared in parental and MCF-10A/Myc-MAL2 cells. As shown in Figure 9a, MCF-10A/Myc-MAL2 cells showed a dramatically elongated morphology relative to the parental cell line, which did not reflect a change in differentiation status, as assessed using neuronal and epithelial-mesenchymal transition markers (data not shown). Increased detection of glycosylated MAL2 in both raft and non-raft fractions from MCF-10A/Myc-MAL2 cells was also accompanied by increased MUC1 detection across all membrane fractions (Figure 9c). Comparing the sub-cellular localisations of these proteins using confocal microscopy revealed an accumulation of MUC1 at the periphery of MCF-10A/Myc-MAL2 cells compared with parental cells, which incompletely co-localised with MAL2 (Figure 9b). Taken together, these data show that ectopic Myc-MAL2 expression in MCF-10A/Myc-MAL2 cells expands the plasma membrane domain, and increases MUC1 detection at the cell periphery.

(b) MCF-10A and MCF-10A/Myc-MAL2 cells were co-stained for MUC1 (left panel) and MAL2 (middle panel). Overlap between the MUC1 and MAL2 proteins are shown in merged images (right panel). Images shown are single horizontal x-y sections. (c) MCF-10A and MCF-10A/Myc-MAL2 cells were extracted with 1% Triton X-100 at 4°C, and centrifuged to equilibrium in sucrose density gradients. Twelve fractions of 1 ml were collected (Fr, as shown above each top panel), and aliquots were subjected to SDS-PAGE and Western blot analysis with MUC1, MAL2 or CAV1 antisera, as indicated at the left, with sizes of detected proteins indicated at the right. Vertical lines between fractions 8 and 9 distinguish samples loaded on different gels. Results shown represent those obtained from 3 independent experiments.
Discussion
MAL2 was first identified through its expression in breast carcinoma and interactions with D52-like proteins within the Y2H system [1]. We therefore undertook a Y2H screen to identify MAL2 binding partners expressed in human breast cancer tissue, which identified a number of novel putative binding proteins, including MUC1. MUC1 represented a candidate partner of particular interest, given the fact that it is overexpressed in cancer types where MAL2 overexpression has also been reported, and as MUC1 overexpression contributes to cancer progression through a number of mechanisms [43,44]. Interactions between human MUC1 and MAL2 proteins are also broadly consistent with the previously reported interactions between the yeast signalling mucin Msb2 and the tetraspanin protein Sho1 [45]. Subsequent results collectively identify MAL2 as a novel cytoplasmic MUC1 partner, and a possible regulator of MUC1 expression and/or subcellular distribution. It is striking to note that MAL2, a chromosome 8q24 amplification target, has now been shown to bind MUC1 and D52, both of which are amplified and/or overexpressed in breast and other cancers [21,22,34,35,46] strongly suggesting that these proteins have co-operating functions in cancer cells.
While a recent study by Kinlough et al. [47] indicated that palmitoylation is the dominant feature modulating MUC1 recycling to the plasma membrane, the mechanisms by which MUC1 is targeted and maintained at the plasma membrane are not fully understood. Since ectopic Myc-MAL2 expression in MCF-10A cells was associated with increased MUC1 detection at the cell periphery in the present study, MAL2 may play a direct or indirect role in MUC1 targeting. Interestingly, MAL2 incompletely co-localised with peripheral MUC1 in MCF-10A/Myc-MAL2 cells, which supports previous findings that altering MAL2 expression can alter cargo accumulation distant to the predominant site of MAL2 expression [2,14]. However, ectopic Myc-MAL2 expression also produced an apparent expansion of cell surface domains in MCF-10A cells, which may also contribute to increased MUC1 detection at the cell periphery. Similar observations have been made in a previous study where MAL overexpression altered the morphology of MDCK cells, by seemingly expanding apical cell surface domains through increased apical delivery [6]. Finally, we also noted that ectopic MAL2 expression produced an increase in MUC1 detection across Triton X-100-soluble and -insoluble protein fractions in MCF-10A/Myc-MAL2 cells, indicating that Myc-MAL2 may positively regulate MUC1 expression. This may also lead to increased peripheral MUC1 detection. While it remains to be determined whether MAL2 can alter MUC1 distribution in other cell types, the broad expression of MAL2 within epithelia [13] is consistent with MAL2 contributing to MUC1 targetting under physiological conditions. It will also be of interest to examine whether MAL2 can similarly regulate MUC1 secretion.
If MAL2 similarly regulates MUC1 expression and/or distribution in cancer cells, increased MAL2 levels could alter cancer cell biology in several ways. Increased MUC1 localisation at the cell surface could reduce intercellular adhesion and promote invasiveness [44], and increased MAL2 expression would thus be expected to have adverse significance in cancer cells. Accordingly, MAL2 has been included within a gene signature of poor prognosis in breast cancer [48], and MAL2 overexpression was associated with resistance to doxorubicin therapy in breast cancer patients [49]. MAL2 overexpression might also reduce cytoplasmic MUC1 accumulation, which has been indicated to be an adverse finding in breast and ovarian carcinomas [50-52], tumor types which also overexpress MAL2 [20,24,25]. Interestingly, suppression of MUC1 expression in a pancreatic cancer cell line reduced these cells' metastatic potential, and was accompanied by reduced MAL2 levels [53]. Further direct analyses are therefore required to determine whether MAL2 and MUC1 levels are positively correlated in cancer types commonly expressing these proteins, and whether MAL2 expression is significantly associated with cell surface expression of MUC1 in cancer cells.
The present study also provides the first report that MUC1 localises within lipid raft fractions in breast carcinoma cells, and raises the possibility that some of MUC1's signalling functions [43,44] may occur within lipid rafts. Previous studies reported that MUC1 in T-lymphocyte cell lines was insoluble in cold Triton X-100 and associated with low density membrane fractions [54,55], yet Kinlough et al. [47] showed MUC1 from MDCK cells was fully soluble in Triton X-100. The reported differences in MUC1 solubility may be due to cell specific differences in membrane composition and their selectivity for detergents, as reported by Schuck et al. [56], or alternatively MUC1 may not reside in lipid rafts in all cell types. We demonstrated associations between MUC1 and MAL2 in Triton X-100 soluble fractions, in agreement with MUC1 and MAL2 being predominantly detected in non-raft fractions in all cell lines analysed, which was also noted for the MAL2 partner D52. While we were unable to determine whether MAL2 and MUC1 associate within lipid rafts, our results indicate that MAL2 associates with MUC1 and potentially other proteins outside lipid raft membrane microdomains, as indicated for other tetraspanins [57], and highlights the fact that MAL2 may have independent functions within and outside lipid rafts.
Our analysis of MAL2 partners has also indicated that MAL2 may represent a multifunctional transmembrane adaptor protein, capable of binding more than one partner simultaneously. We noted that both MAL2 and D52 co-immunoprecipitated with MUC1 in the present study, despite the fact that direct interactions between MUC1 and D52 were not detected in the Y2H system. Independent interaction domains for MAL2/MUC1 and MAL2/D52 binding were also indicated by the MAL2 N-terminal domain being required to bind D52-like proteins, yet the first TM domain was required for binding MUC1. Correspondingly, D52-like proteins did not bind MAL, whose N-terminal sequence is poorly conserved with respect to that of MAL2 [1], yet MUC1 bound both MAL and MAL2 in the Y2H system. These results therefore predict shared and isoform-specific functions for MAL-like proteins, through shared and discrete binding partners.
Conclusion
This study has identified MAL2 as a novel cytoplasmic MUC1 partner and a potential regulator of MUC1 subcellular distribution. MAL2/MUC1 interactions were detected in Triton X-100-soluble membrane fractions, indicating that MAL2 has specific functions within non-raft membrane compartments in breast cancer cells. Since MAL2 is known to be amplified and overexpressed in breast and other cancers, it is striking that MAL2 has now been shown to bind two proteins, MUC1 and D52, which are also amplified and/or overexpressed. Based on these results, and a previous study highlighting the co-amplification of MAL2 and D52 genes in breast cancer [21], it will be interesting to examine whether MAL2 and MUC1 are commonly amplified and overexpressed in breast cancer, and whether MAL2 expression is significantly associated with cell surface expression of MUC1.

Abstract
Background
Lower extremity peripheral arterial disease (PAD) is a marker of widespread atherosclerosis. Individuals with PAD, most of whom do not show typical PAD symptoms ('asymptomatic' patients), are at increased risk of cardiovascular ischaemic events. American College of Cardiology/American Heart Association guidelines recommend that individuals with asymptomatic lower extremity PAD should be identified by measurement of ankle-brachial index (ABI). However, despite its associated risk, PAD remains under-recognised by clinicians and the general population and office-based ABI detection is still poorly-known and under-used in clinical practice. The Prevalence of peripheral Arterial disease in patients with a non-high cardiovascular disease risk, with No overt vascular Diseases nOR diAbetes mellitus (PANDORA) study has a primary aim of assessing the prevalence of lower extremity PAD through ABI measurement, in patients at non-high cardiovascular risk, with no overt cardiovascular diseases (including symptomatic PAD), or diabetes mellitus. Secondary objectives include documenting the prevalence and treatment of cardiovascular risk factors and the characteristics of both patients and physicians as possible determinants for PAD under-diagnosis.
Methods/Design
PANDORA is a non-interventional, cross-sectional, pan-European study. It includes approximately 1,000 primary care participating sites, across six European countries (Belgium, France, Greece, Italy, The Netherlands, Switzerland). Investigator and patient questionnaires will be used to collect both right and left ABI values at rest, presence of cardiovascular disease risk factors, current pharmacological treatment, and determinants for PAD under-diagnosis.
Discussion
The PANDORA study will provide important data to estimate the prevalence of asymptomatic PAD in a population otherwise classified at low or intermediate risk on the basis of current risk scores in a primary care setting.

Background
Lower extremity peripheral arterial disease (PAD) is considered to be a marker of widespread atherosclerosis. In patients without overt cardiovascular disease (CVD), the presence of PAD predicts approximately a 30% risk of myocardial infarction, ischaemic stroke, and vascular death over 5 years. Patients with PAD show a 2- to 6-fold increase in death from cardiovascular causes and a greater risk of limb amputation than those without PAD. Individuals with PAD also experience higher 1-year rates of cardiovascular death (2.5%) and major cardiovascular events (21.1%) caused by an increase in atherothrombotic events, compared with patients with coronary artery disease (1.9% and 15.2%, respectively) or with any cerebrovascular disease (2.1% and 14.5%, respectively) [1-7].
Despite its association with severe health risk, PAD remains under-recognised by clinicians and the general population [8,9]. This may be due to the fact that the majority of individuals with lower extremity PAD do not experience recognisable ischaemic symptoms in the limb and are considered 'asymptomatic'. Nevertheless, these individuals share the unfavourable cardiovascular prognosis of symptomatic patients, as they show a risk profile comparable to that of patients with symptomatic lower extremity PAD or with coronary heart disease (CHD) [1,2,10,11]. Patients diagnosed with PAD, including those with asymptomatic PAD, should be treated to reach the recommended therapeutic goals, including low-density lipoprotein cholesterol (LDL-C) target levels <2.6 mmol/L (100 mg/dL) [12], which are similar to those recommended for high risk patients, i.e. those with CHD or CHD risk equivalents - although more challenging than that recommended for individuals at moderate CVD risk, i.e. 3.3 mmol/L (130 mg/dL) [2,12,13].
Ankle-brachial index (ABI) value ≤0.90 is the recognised cut-off for diagnosis of PAD. According to a few observational studies, pathological ABI values are frequently observed among elderly patients (aged 70+ years or 50-69 years but with a history of cigarette smoking) who are otherwise not classified as high risk [1,2]. Indeed, the prevalence of a pathological ABI still remains substantially unknown among patients classified at intermediate or low risk according to the current risk scores. The American College of Cardiology (ACC)/American Heart Association (AHA) guidelines recommend screening for both symptomatic and asymptomatic PAD, by physical examination and/or ABI measurement, in order to identify patients with asymptomatic lower limb PAD and to offer appropriate therapeutic interventions that diminish risk of myocardial infarction, stroke, and death.
Hence, the Prevalence of peripheral Arterial disease in patients with a non-high CVD risk, with No overt vascular Diseases nOR diAbetes mellitus (PANDORA) study was designed to provide updated information on the prevalence of PAD, in the context of traditional risk factor assessment, and insight on clinical characteristics as possible determinants for PAD under-diagnosis.
Methods/Design
PANDORA is a non-interventional, cross-sectional, pan-European study of patients with a non-high CVD risk, defined as having at least two CVD risk factors according to National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III [ATP III]) guidelines, with no overt CVDs or diabetes mellitus. Patients with definite symptoms of PAD will be also excluded (ClinicalTrials.gov Identifier: NCT00689377).
Approximately 1,000 sites will participate in the study in six European countries (Belgium, France, Greece, Italy, The Netherlands, Switzerland). Study objectives and selection criteria are listed in Table 1. Since the majority of individuals with a CVD risk factor score of 0 or 1 have a low 10-year risk, i.e. below 10%, these patients are excluded from the study population [13]. Study variables, as listed in Table 2, are collected in the Subject Record Form. Data are captured electronically in most participating countries.
Table 1. Study objectives and selection criteria
Table 2. Data captured in the Patient Record Form (PRF)
Prior to the inclusion of the first patient, investigators are requested to complete an Investigator Questionnaire regarding their personal experience and perception of the management of CVD risk, and attitude towards CVD diagnosis, guidelines and goals. The study will collect data on knowledge and behaviour in CVD diagnosis and management, quantity of CVD cases experienced, and attitudinal statements about guidelines and goals.
Patients recruited will be asked to complete a Patient Questionnaire which aims to collect data on awareness of CVD risk factors, knowledge and awareness of PAD, CVD risk perception and treatment, frequency of medical appointments.
The study conforms to the ethical principles outlined in the Declaration of Helsinki and is consistent with ICH/Good Clinical Practice, applicable regulatory requirements, and the AstraZeneca policy on Bioethics.
ABI measurement
Each investigator receives theoretical and practical training on the ABI measurement technique according to ACC/AHA guidelines for the management of patients with PAD [1,2]. Right and left ABI measurement is performed at rest by measuring the systolic blood pressure from both brachial arteries and from both the dorsalis pedis and posterior tibial arteries after the patient has been at rest in the supine position for 10 minutes. Measurements are taken with blood pressure cuffs that are appropriately sized to the patient's lower calf (immediately above the ankle). The hand-held Doppler ultrasonography instrument Elite 100R, Nicolet Vascular Inc. (Golden, Colorado, USA), with an 8 MHz vascular probe, is used to measure systolic pressures and ABI. The Elite 100R vascular Doppler device was chosen since it has been used in major published studies on PAD detection [1,14]. The 8 MHz probe is preferred over the 5 MHz probe, due to its higher sensitivity and reliability in detecting both superficial and deep arteries.
For ABI calculations, the higher of the two brachial artery systolic pressures, and the higher of the dorsalis pedis and posterior tibial pressures in each ankle, are selected. The right and left ABI values are separately calculated by dividing the higher of the two ankle systolic pressures in that leg by the higher brachial artery systolic pressure. Calculated ABI values are recorded to two decimal places. Each patient is considered to have PAD if ABI in either leg is 0.90 or less [1,2,15].
Statistical analysis
The statistical analyses will be descriptive in nature. Data will be presented as mean ± standard deviation or median with minimum and maximum. Summary data will be presented from all available data. Categorical data will be described by the number and percentage of patients in each category. Missing observations will be presented in tables as a separate category. The calculation of proportions will not include the missing category.
The primary objective of this survey is to determine the proportion of patients with pathological ABI, according to ACC/AHA guidelines for the management of patients with PAD. The overall sample size calculations were based on a confidence interval approach to ensure that the estimates will have adequate precision. A reasonable requirement on the precision is that the incidence should be determined within ± 1%, i.e. the length of the two-sided 99% confidence should not exceed 1 percentage value in each direction from the estimated value. Based on these calculations and expecting a 15% prevalence of individuals with pathological ABI in the selected population [14], the minimum sample size considered sufficient to meet the objectives of this protocol is 8,454 patients. However, to account for potential drop-outs, the survey plans to enrol 9,000 patients. Such sample size also ensures that the proportion reporting on the primary endpoint can be estimated with sufficient precision, on a 'by-country' basis, to represent the country-based heterogeneity of this population.
Results and discussion
PAD, especially in the asymptomatic stage is common, and its prompt screening and treatment can reduce cardiovascular risk [2].
Although PAD shares the same risk factors of other CVDs and the guidelines recommend the same preventive treatments and therapeutic targets, there is low awareness of PAD (26% for PAD, compared with 74% for stroke, and 67% for coronary artery disease and heart failure, respectively) [8]. There appears to be greater awareness even of a rare disease such as Lou Gehrig's disease (36%), or conditions such as multiple sclerosis (42%) and cystic fibrosis (29%) [12].
The detection of asymptomatic people with an ABI ≤0.90 allows for the identification of a subgroup at higher cardiovascular risk than can be determined based on the usual CVD risk assessment. Diagnosis of asymptomatic PAD in such a population assigns these individuals to the 'secondary prevention risk level' [12].
ABI measurement is now accepted as a simple and reliable vascular test to assess leg perfusion. ABI testing is appropriate in populations targeted from the epidemiological database to be at risk for PAD. Among patients with no history of CVD or diabetes, ABI measurement is recommended in certain categories appearing to be at moderate CVD risk, including individuals at higher-risk ages, and with risk factors typically associated with PAD, such as cigarette smoking [2]. Quite recently, Cacoub et al. assessed the prevalence of PAD in a population of patients with two or more cardiovascular risk factors [16]. Diehm et al. provided data on the prevalence of PAD in a large population of unselected individuals aged ≥65 years from the primary care setting [17]. However, data on the prevalence of asymptomatic PAD in a large population otherwise classified at low or intermediate risk are lacking.
Office-based detection of ABI is the most cost-effective tool for lower extremity PAD detection and provides objective data both for the diagnosis in epidemiological surveys and in-office practice, and monitoring of efficacy of therapeutic interventions [2,18,19].
ACC/AHA guidelines state that the initial responsibility for the detection of lower extremity PAD should be with primary-care providers, because such providers are best positioned to determine an at-risk population and to initiate educational, lifestyle, and cardiovascular risk reduction therapies [2].
Conclusions
Low awareness of PAD and scarce familiarity with the ABI technique seems to greatly undermine the diagnosis of asymptomatic PAD patients, who are at comparable risk to patients with CHD and should be appropriately treated. Unfortunately, most asymptomatic patients do not receive a diagnosis of PAD prior to the occurrence of a morbid or fatal ischaemic disease or event [1,2]. This is particularly true for individuals with asymptomatic PAD otherwise classified at low or intermediate risk on the basis of current risk scores. Information on the prevalence of asymptomatic PAD in such a setting is lacking. Improving PAD awareness among clinicians and the public is crucial for effective CVD prevention, early detection and integrated treatment. The PANDORA study will provide important pan-European data to estimate the prevalence of asymptomatic PAD in people with a non-high CVD risk in a primary care setting, by using the ABI technique, a risk-free gold-standard diagnostic test for PAD. This study may provide additional insights on identifying an at-risk segment of population that may benefit from appropriate preventive therapy.

Kee Sze Seen, Shamsul Bahri Mohd Tamrin, Goh Yong Meng
Abstract
Introduction: Motor vehicle accident is a major problem in Malaysia. The statistics shows an increasing number
of accidents (year 1997 to 2007). Fatigue and drowsiness among the drivers has been identified as one of the
main reasons behind fatal crashes and injuries especially driving in long and monotonous motorway. This study
aims to determine the driver’s driving performance and physiological change of EEG in association with external
factors such as driving condition and environmental background factors in a prolonged simulation study. Result:
The study showed that time-on-task effect had significantly deteriorated drivers’ alertness and impaired driving
performance in an extended driving period, when certain driving condition and environmental factors considered.
Conclusion: This study shows that prolong driving had significantly induced drivers’ fatigue level exclusively
with monotonous environment. Extended driving period deteriorated drivers’ performance, revealing that
time-on-task effect could possibly put drivers on a higher risk to be involved in traffic accident.

T. Doan, D. Babu, R. Buescher
Abstract
This study investigated the inhibition of yeasts in brines from fermented cucumber pickles using 2, 4-hexadienoic (sorbic), hexanoic and (E)-3-hexenoic acids. Native yeast population and chemical composition of commercial brines were analyzed and the minimum inhibitory concentrations of inhibitors on yeast growth were established. Commercial brines were treated with 100-350 ppm of 2, 4-hexadienoic (sorbic), hexanoic and (E)-3-hexenoic acids individually and at 2.5 to 10% salt (sodium chloride) concentrations. Yeast populations in the treated brines were monitored for 30 days of incubation. Hexanoic and (E)-3-hexenoic acids at 350 ppm caused reduction in yeast populations by about 4 and 2 log CFU/ml, respectively, within 24 hours of treatment. However, when brines were treated with 2, 4-hexadienoic acid at salt concentrations of 7.5 to 10%, there were no significant differences noted in yeast inhibition between the three acids. Hexanoic and (E)-3-hexenoic acids at 200 ppm caused longer lasting inhibitory effects (30 days) on yeasts than the traditionally used 2, 4-hexadienoic acid (10 days) in fermentation brine. Thus, the hexanoic and (E)-3-hexenoic acids are potential alternatives to 2, 4-hexadienoic acid for controlling yeasts during storage of spent cucumber fermentation brines.

Climate Adaptation of Rice
Symbiogenics: A New Strategy for Reducing Climate Impacts on Plants
Rice–which provides nearly half the daily calories for the world’s population–could become adapted to climate change and some catastrophic events by colonizing its seeds or plants with the spores of tiny naturally occurring fungi. In an effort to explore ways to increase the adaptability of rice to climatic scourges such as tsunamis and tidal surges that have already led to rice shortages, USGS researchers and their colleagues colonized two commercial varieties of rice with the spores of fungi that exist naturally within native coastal (salt-tolerant) and geothermal (heat-tolerant) plants.
The rice plants thrived, achieving notable increased tolerance to cold, salt and drought, even though the rice varieties they tested were not naturally adapted to these stressors. Conferring heat tolerance to rice is the next step for the research team since rice production decreases by 10 percent for every temperature increase of 1-degree centigrade during the rice-growing season.
"This is an exciting breakthrough," Rusty Rodriguez, Ph.D. said. "The ability of these fungi to colonize and confer stress tolerance, as well as increased seed yields and root systems in rice–a genetically unrelated plant species from the native plants from which the fungi were isolated—suggests that the fungi may be useful in adapting plants to drought, salt and temperature stressors predicted to worsen in future years due to climate change."
In fact, said Rodriguez, using these tiny fungi–called endophytes–is one of the only real strategies available for mitigating the effects of climate change on plants in natural and agricultural ecosystems. "We have named this emerging area of research symbiogenics for symbiosis-altered gene expression. The DNA of the rice plant itself, however, is not changed. Instead, we are re-creating what normally happens in nature. And with rice yields projected to decrease by 15 percent in developing countries by 2050, such strategies are needed."
The way it works is this. All plants seem to have symbiotic endophytes—microscopic fungi or bacteria—living in them that do not cause disease in the plant. The kind of endophytes that Rodriguez and his colleagues examined are all mutualistic, meaning the plant and the fungi have a close and positive relationship that bestows benefits on both partners: stress tolerance for the plant, nutrients and a lack of competition for the fungus.
The scientists took fungal endophytes from dunegrass, a species exposed to seawater and therefore salt-tolerant, and colonized the rice plants and seeds with its fungal spores, which germinated and infiltrated the plant’s tissue. The results were dramatic: the endophytes reduced water consumption of the plant by up to one half, and increased its growth, the number of seeds it produced, and how much it weighed by as much as 50 percent.
"Conventional thinking was that the dunegrass is salt tolerant because of genetic adaptations that occurred over time (the process of Darwinian evolution), but we found that when we removed the fungus from dunegrass, the plants were no longer salt tolerant," Rodriguez said. "This means that plants in natural habitats may not be adapting themselves genetically to the stress, but instead are establishing a beneficial partnership with a fungus that makes them more salt tolerant."
During the last 40 years of climate change, the authors pointed out, the minimum air temperature in rice-growing season has increased in China and the Philippines, resulting in a substantial decrease in rice yields there, decreases predicted to continue. "Collectively, these events, along with an increasing world population, have contributed to shortages and increased prices of rice, exacerbating hunger and famine issues globally."
The authors emphasized that even though it may be possible to compensate for some of the effects of climate change by incorporating, say, earlier-producing varieties of rice into agricultural practices, the adaptive capabilities of rice will be what ultimately determines how severely climate change affects the annual yield of rice.
The research, Increased Fitness of Rice Plants to Abiotic Stress via Habitat Adapted Symbiosis: A Strategy for Mitigating Impacts of Climate Change, was published in PLoS One, and is available online.

Abstract
Shilajit is a natural substance found mainly in the Himalayas, formed for centuries by the gradual decomposition of certain plants by the action of microorganisms. It is a potent and very safe dietary supplement, restoring the energetic balance and potentially able to prevent several diseases. Recent investigations point to an interesting medical application toward the control of cognitive disorders associated with aging, and cognitive stimulation. Thus, fulvic acid, the main active principle, blocks tau self-aggregation, opening an avenue toward the study of Alzheimer's therapy. In essence, this is a nutraceutical product of demonstrated benefits for human health. Considering the expected impact of shilajit usage in the medical field, especially in the neurological sciences, more investigations at the basic biological level as well as clinical trials are necessary, in order to understand how organic molecules of shilajit and particularly fulvic acid, one of the active principles, and oligoelements act at both the molecular and cellular levels and in the whole organism.
1. Introduction
Shilajit also known in the north of India as salajit, shilajatu, mimie, or mummiyo is a blackish-brown powder or an exudate from high mountain rocks, especially in the Himalayans mountains between India and Nepal, although it has been also found in Russia, Tibet, Afghanistan, and now in the north of Chile, named as Andean Shilajit [1]. Shilajit has been known and used for centuries by the Ayurvedic medicine, as a rejuvenator and as antiaging compound. There are two important characteristics of a rasayana compound in the ancient Indian Ayurvedic medicine: that is, to increase physical strength and to promote human health [2]. The health benefits of shilajit have been shown to differ from region to region, depending on the place from which it was extracted [3, 4].
2. Origins of Shilajit
Considering its unique composition as a phytocomplex, very rich in fulvic acid, researchers hypothesize that Shilajit is produced by the decomposition of plant material from species such as Euphorbia royleana and Trifolium repens [4, 5]. This decomposition seems to occur through centuries, and on this basis, shilajit is considered a millenary product of nature. However, further studies have identified that several other plant organisms may generate shilajit, such as molds as Barbula, Fissidens, Minium, and Thuidium and other species like Asterella, Dumortiera, Marchantia, Pellia, Plagiochasma, and Stephenrencella-Anthoceros [4].
3. Molecular Composition of Shilajit
Shilajit is composed mainly of humic substances, including fulvic acid, that account for around 60% to 80% of the total nutraceutical compound plus some oligoelements including selenium of antiaging properties [6, 7] (Figure 1). The humic substances are the results of degradation of organic matter, mainly vegetal substances, which is the result of the action of many microorganisms. Components are divided operationally in humins, humic acid, and fulvic acids according to their solubility in water at different pH levels. Humins are not soluble in water under any pH condition. Humic acid is soluble in water under alkaline conditions and has a molecular weight of 5–10 kDa. Fulvic acid is soluble in water under different pH conditions, and because of its low molecular weight (around 2 kDa), it is well absorbed in the intestinal tract and eliminated within hours from the body [8, 9]. It is likely that the curative properties attributable to shilajit are provided by the significant levels of fulvic acids that shilajit contains, considering that fulvic acid is known by its strong antioxidant actions [9] and likely has systemic effects as complement activator [10]. Recent studies on the composition of Andean Shilajit in Chile have evidenced an ORAC index between 50 and 500 Trolox units/g of material, which is substantially higher than Noni and blueberries (Quinteros et al., unpublished data). In this context, shilajit seems to be a powerful antioxidant phytocomplex.
Figure 1: Shilajit, its main components, and potential uses based on properties of fulvic acid. This phytocomplex known as shilajit is mainly composed of humic substances. One of them, fulvic acid, is known by its properties such as antioxidant, anti-inflammatory, and memory enhancer. Novel investigations indicate that fulvic acid is an antiaggregation factor of tau protein in vitro [1], which projects fulvic acid as a potential anti-Alzheimer’s disease molecule.
Other molecules present in shilajit preparations are eldagic acid, some fatty acids, resins, latex, gums, albumins, triterpenes, sterols, aromatic carboxylic acids, 3,4-benzocoumarins, amino acids, polyphenols, and phenolic lipids [3, 6, 11]. Certainly its molecular composition varies from region to region. Newer investigations based on high-performance size exclusion chromatography (HP-SEC) show that shilajit contains specific molecular species of polysaccharides and lignins [10]. As humic components, humins, humic acids, and fulvic acids are found in all shilajit preparations, being the last one, fulvic acids, the biologically active compound, along with dibenzo--pyrones, which acts as carrier of other substances [3].
4. Traditional Uses of Shilajit
Shilajit is an important, known component of the ayurvedic medicine given its characteristics as a rasayana. In this context, health benefits such as an increase in longevity, rejuvenating, and arresting aging roles have been attributed to it [3]. Traditionally, shilajit is consumed by people from Nepal and the North of India, and children usually take it with milk in their breakfast. The Sherpas claim to have shilajit as part of their diet; they constitute a population of strong men with very high levels of a healthy longevity. Our laboratory has found evidence on the high activity of the Andean form of shilajit in improving cognitive disorders and as a stimulant of cognitive activity in humans [1] (Table 1).
Table 1: Morphometric study of primary cultured rat hippocampal cells exposed to Shilajit and the Brain Up-10 formulae that contain Shilajit plus complex B vitamins (Vit B6, B9, and B12).
Considering the actions of fulvic acid in preventing tau self-aggregation into pathological filaments, this compound appears to be of interest for prevention of Alzheimer’s disease [1]. Other common traditional uses include its action in genitourinary disorders, jaundice, digestive disorders, enlarged spleen, epilepsy, nervous disorders, chronic bronchitis, and anemia [2]. Shilajit has been also useful for the treatment of kidney stones, edema, and hemorrhoids, as an internal antiseptic, and to reduce anorexia. Also, it has been claimed in India to be used as yogavaha [12, 13], that is, as synergistic enhancer of other drugs. Organic components of shilajit play also a role in transporting different mineral substances to their cellular targets.
5. Novel Investigations
Preclinical investigations about shilajit indicate its great potential uses in certain diseases, and various properties have been ascribed, including (1) antiulcerogenic properties [14]; (2) antioxidant properties [15, 16]; (3) cognitive and memory enhancer [1, 10, 17]; (4) antidiabetic properties [18]; (5) anxiolytic [12]; (6) antiallergic properties and immunomodulator [2, 19, 20]; (7) anti-inflammatory [21]; (8) analgesic [16]; antifungal properties [22]; (9) ability to interact positively with other drugs [23]; (10) protective properties in high altitudes [24]; (11) neuroprotective agent against cognitive disorders [1, and Farias et al. unpublished clinical trials]. Unfortunately shilajit lacks systematic documentation and well-established clinical trials on its antioxidative and immunomodulatory actions in humans, and it is expected that considering the reported benefits evidenced from trials will be obtained in the near future [25].
6. Patenting
A few patents already exist that protect the use of shilajit in India and Nepal, such as US Patent 5,405,613—vitamin/mineral composition [26]; US Patent application number 20030198695—Herbo-mineral composition [27]; US Patent number 6,440,436—Process for preparing purified shilajit composition from native shilajit [28]; US Patent number 6,558,712—Delivery system for pharmaceutical, nutritional and cosmetic ingredients [29]. Other recent patent about a phytocomplex with vitamins added is WO 2011/041920 [30].
7. Potential Risks
Studies indicate the shilajit consumption without preliminary purification may lead to risks of intoxication given the presence of mycotoxin, heavy metal ions, polymeric quinones (oxidant agents), and free radicals, among others [3]. Therefore, a purified, ready-for-use preparation for human consumption must be used. However, recent studies indicate that several ayurvedic products including shilajit and other Indian manufactured products commercialized by the Internet may contain detectable heavy metals levels as lead, mercury, and arsenic [31]. This study showed the presence of heavy metals and other minerals, including gems, is associated with the belief that when mixed with shilajit or other herbal preparations they generate a better response from the body in a synergic manner. This is what is known as rasa-shastra in ayurvedic medicine. Rasashastra experts claim that if this is prepared, administered, and consumed properly, it is safe and has therapeutic advantages [31]. It is worth considering that recent clinical reports indicate cases of lead poisoning in patients who have used ayurvedic products against weakening [32, 33].
8. Commentary and Discussion
Shilajit has a comfortable position as the rasayana because of its excellence, well known in the Eastern culture, and now being introduced with great interest in the occidental world. The vast majority of published papers on this theme are from India, leaving this sector of the planet as an expert in their field, since this is a product that is extracted, marketed, and investigated in these latitudes. However, this generates a segmentation of shilajit, relegating it only to what has always been assumed: a natural product that is part of natural alternative medicine and not as a result of medical and biotechnology innovation worldwide. This is evidenced quite clearly by reviewing the literature today, and note that the journals where studies on shilajit are published (jobs are plentiful) are mainly reviewed in the Eastern. Given this, it is necessary that shilajit break the cultural paradigm and enter into the rest of the world by the hand of rigorous research at the molecular and cellular levels, which could elucidate the interactions of the active ingredients of the different shilajit preparations with biomolecules. This will facilitate our understanding of their mechanisms of action.
9. Conclusion
Shilajit is a potent and very safe dietary supplement, potentially able to prevent several diseases, but its main medical application now appears to come from its actions in benefit of cognition and potentially as a dietary supplement to prevent Alzheimer’s disease. In essence, this is a nutraceutical product. Considering the expected impact of shilajit applications in the medical field, especially in neurological sciences, more investigations at the basic biological level are necessary, and certainly well-developed clinical trials, in order to understand how its active principles act at molecular and cellular levels.

} | cccc_CC-MAIN-2013-20 | Nancy Pelosi's Bar Tab Proves That Absolute Power Corrupts, (Intoxicates)
by the Left Coast Rebel
Nancy (Nasty) Pelosi is a Horrible Woman. Yes she is, simply one of the worst of a lot of bad characters in Washington that stretches a mile long. The picture above is the only one that I could find of her with her mouth shut too, by the way. For every time that she does open it, I hear another precious freedom (or a trillion dollars) get whisked away. At a time when Americans are suffering Nancy Pelosi jetted over to Copenhagen with 3 military jets last month spending (millions?) at taxpayer's expense to prove what an elitist, smug, aristocrat she is.
The most ridiculous thing about aristocrats like Nasty Pelosi, Harry Reid, Schumer, Obama, Clinton(s), Frank....fill in the rest here, is that these 'royalty' preach to masses from atop the perch of the altruist socialist-progressive. They are for the little guy. They feel your pain. They will stick it to the man. And you know what? It is just a simple way to take away our freedoms and liberties, bring all income levels down to a lower level and increase the entire nation's misery. Except for them.
Today's leadership is probably one (if not the) worst in American history. They are power drunk and Nancy Pelosi is one of the drunkest of the drunks, literally:
Maker's Mark whiskey,
Courvoisier cognac,
Johnny Walker Red scotch,
Grey Goose vodka,
J&J brandy,
Bailey's Irish Crème,
Bacardi Light rum,
Jim Beam whiskey,
Beefeater gin,
Dewars scotch,
Bombay Sapphire gin,
Jack Daniels whiskey … and Corona beer
.
Nancy Pelosi's bar tab, paid for by the United States taxpayer, all above. 2 year cost to the taxpayer for drinks catered to her by you and I while gallivanting all over the nation (and world)?
--$101,000.00
Cost of the Air Force Fleet that she uses to whisk between DC and San Francisco over the last 2 years?
--$2,000,000.00
Why not, if we let them do this to us?
UPDATED:
Thomas Paine did some heavy lifting and the legwork involved digging up history on 'Queen' Pelosi including her lack of business experience whatsoever. It is quite illimunating when you read the background of someone like Pelosi. Thanks for the research Thomas. Visit his excellent site, Save Us From the World Improvers

From the Super Mario Wiki
Jump to: navigation, search
Wario using Gas Mask!.
Gas Mask! is the name of a Super Ability executed by Wario in Mario Strikers Charged. Wario will only be able to use Gas Mask! when he collects his special item, which is shown as his own head. When Wario uses Gas Mask!, he will fart, leaving a trail of toxic gas behind him. A player can use this ability at nearly any time, such as when he's standing up, or when Wario's getting back up from being tripped. Also, when using Gas Mask! while running, Wario runs a little bit faster, like when Waluigi uses Wall-Luigi!. When doing a one-timer and using Gas Mask!, the sound effects will play in slow motion. Any player (besides Wario or Kritter) that walks into this gas will have their controls flipped as if the player were holding his or her Wii Remote and Nunchuk sideways. This will sometimes lead the players into the Electric Fence, or on Thunder Island, straight off the edge. Wario can use this Super Ability four times in one item. Gas Mask! can be used to trap Wario in a corner, allowing a safe Mega Strike. However, if another player uses a Starman, they can run into the gas and get the ball back without any harmful effects. This Super Ability, like Wario's Wario Waft in Super Smash Bros. Brawl, probably caused the Crude Humour label on the ESRB Rating. However, the slightly rude things they do to each other could also cause the label.
If any opposing Captains walk into the gas, they will say something to Wario. For example, Mario will say "Mamma mia," and start choking, or say "Oh, Wario," and cough. Waluigi will tell Wario to change his pants, hold it in, or say "Oh, Wario, you're killing me!". For Daisy, she will say "Ohhh, Wario!!". If Bowser's Fire Storm! is used nearby Gas Mask!, a big explosion will occur, and if Wario is nearby, both Wario and Bowser will be sent flying.

} | cccc_CC-MAIN-2013-20 | In House: Big SEO
Apr 10, 2007 • 10:17 am | (3) by | Filed Under Search Engine Strategies 2007 New York
What matters when doing big SEO for big brands or big sites with thousands of products? This session will discuss the problems and solutions that marketers run into when faced with such large issues and the best way to handle them.
Jeffery Rohrs opens the session welcoming everyone to the session. It is a very packed and hot session with this the first session about doing SEO in house. Looks like it will be a very good session.
Bill Hunt the CEO of Global Strategies starts first to talk about SEO for big brands. He begins talking about Enterprise key focus areas for large companies and what has the most success. He recommends integrating SEO best practices into the organization at the right levels. Next, implement internal protocols to minimize unexpected problems. Third, integrate search into the web development and management workflow. Style guides and web rule books are important to help dictate search practices. Style guides tell developers where exactly pixels go and so on. These documents can be very detailed but also very important part of the SEO process. Bill will next discuss proving the concept and discussing any missed opportunity matrix will get management support.
So how do you change management? You need to centralize your efforts for success. He puts up a very useful chart of the ways to integrate all the various parts of a big brand into the search marketing initiates. He gives the example of the management team has never met the web team. They meet and exchange cards and chat up the meeting. They can been in the same building but never interact. He says that you need to get these various groups together. Press release team, TV, advertising all need to be part of the process. In a large organization you need to segment the program and look at the infrastructure of the organization. He says they usually hold a best practices session and invites everyone to come. They look at it a couple ways. One from the brand level, group level, and corporate level. What will appeal to these various groups.
Bill broke the process down and asks where is the organization today. He recommends to have executive do searches in Google to see where they are. Having standards work very well in organization because it gives them something to follow. After you have identified the problems and set standards you need to next implement the SEO program. Finally you need to attack the web analytics and reporting tool framework. Bill says that search is one of the easiest to measure in the organization.
He talks next about site wide algorithm compliance audit. Look at things of link popularity, contextual relevancy. What is happening? He recommend building a template for page level audits by putting these into an excel spreadsheet. Start with the basics and work to more advanced topics. He says working with the big three is a good place to start. These are things such as the title tag, headers, and content. The second part to his recommendation is to integrate SEO into your content supply chain. He provides an example of mapping out the clients content creation work flow. There are many ways to track the content through a wiki, blog, articles, etc.. His company also takes a look at style guides. Monitor the infrastructure is also important in order to look for problems that big arise. Pages ranking for words that don’t make sense is a good idea to look at. He recommends creating a page ranking score card and additionally identifying a missed opportunity matrix. He next puts up a document showing the success for certain keywords. He said they call the slide the no bullshit slide, because it highlights how the site is doing in the rankings.
One important ways to understand the cost of not ranking is to show missed opportunity for not ranking well. What does it cost in PPC when you don’t rank in the organic results.
Marshall Simmons from the New York Times starts saying they work with a lot of specific content and organization. He says there are a lot of challenges dealing with 11 million documents, such as looking at why an email registration wall might not be a good idea, also a paid subscription wall and dealing with journalists, editors and guides. The New York times has a company ego which makes it difficult to change different styles of writing and a lot of effort involved in changing the approach to content and SEO.
He next talks about About.com and the integration with the New York Times. About.com is very serious about search and says there will also be opportunity for growth in traffic. So how does About.com get results? They say organized, there is an on-site SEO program manager. They want to engage the team of marketing, technology, research, editorial, and even sales. The SEO are imbedded strategists. In charge of breaking down the areas that need to be analyzed. Small changes could generate major results, affecting vast majority of pages. He gives an example of moving the NYT registration wall back 5 pageviews. More making templates changes that affected entire sections. Cleaning up code is also important. Global search and replaces to remedy spam problems.
Marshall mentions that education is very a important part of the process. Everyone gets one sheet they can refer too. Do ongoing in-depth training sessions. Perform separate training session for technical staff, design, and editorial. Execute strategy and measure results on an ongoing basis. Funny, he says that metrics saves jobs! You have to track way is going on. You need to set baselines monthly, not weekly in order to no what is going on. If you are a publicly traded company these numbers are beneficial to report to investors and all those involved.
So what can big brands do today? Hire an in-house search specialist or SEO project manager. Establish an internal SEO team. Start looking at where you can make the most money. Use solutions like Omniture, WebTrends, Hitwise, etc.. Monitor spider visits, cozy up to IT and do some logfile analysis. Use those results to manage up. Think about metrics that make sense across the company.

Hempstead County is Arkansas's fourth county, formed on December 15, 1818, alongside Clark and Pulaski counties. The county is named for Edward Hempstead, a delegate to the U.S. Congress from the Missouri Territory, which included present-day Arkansas at the time. It is an alcohol prohibition or dry county.
Hempstead County is part of the Hope Micropolitan Statistical Area.
Historic Washington State Park is located in Hempstead County some nine miles northwest of Hope in the historic village of Washington, Arkansas. The state park opened in 1973 as "Old Washington Historic State Park", but the "Old" was dropped from the name in 2006. The park offers walking tours of the historic village, which contains more than a dozen historic structures from the 19th and early 20th centuries.

For information on the insititutional environment of the Australian Bureau of Statistics (ABS), including the legislative obligations of the ABS, financing and governance arrangements, and mechanisms for scrutiny of ABS operations, please see ABS Institutional Environment.
RELEVANCE
Microdata from the Survey of Education and Training (SET) are available as both a Basic and an Expanded CURF.

TIMELINESS
The Survey of Education and Training has been conducted throughout Australia every four years since 1989. The 2009 SET was conducted from March to June 2009. CURFs are also available from previous surveys. The next SET CURF is expected to be released in 2014 based on the survey to be conducted during 2013.
ACCURACY
The 2009 SET CURFs contain individual person level data (unit records) as well as details about qualifications (qualification level) and non-formal training courses (non-formal training level). The CURFs generally contain finer levels of detail of data items than what is otherwise published in other formats, for example, in Education and Training Experience, 2009 (cat. no. 6278.0). The Expanded CURF contains extra data items and a finer level of detail than the Basic CURF. For more information on the level of detail provided in the CURFs, please see the associated data item listing.
Steps to confidentialise the data made available on the CURFs are taken in such a way as to maximise the usefulness of the content while maintaining the confidentiality of respondents selected in the survey. As a result, it may not be possible to exactly reconcile all the statistics produced from the CURFs with other published statistics.
For more information on the survey methodology see Technical Manual: Survey of Education and Training, Basic and Expanded CURFs, Australia (cat. no. 6278.0.55.001).
COHERENCE
Essentially the same methodology has been used in the Survey of Education and Training since 1993, however, the scope of the surveys has differed. While the scope of the 2009 survey included persons aged 15–74 years, the questions focused on persons aged 15–64 years and persons aged 65–74 years who were in or marginally attached to the labour force. The 2005 survey included all persons aged 15 years and over, with those aged 70 years and over asked a subset of questions regardless of their employment status. The 2001 survey included all persons aged 15–64 years. In comparison, the scope of the 1997 and 1993 surveys was narrower still.
A major review of SET, involving consultation with key stakeholders, was undertaken during 2007. The content of the 2009 SET therefore differed somewhat from the 2005 collection reflecting changes that have occurred in the education and training sector in recent years and increased demand for internationally comparable data. In terms of comparison with the 2005 SET, there have also been a number of key questionnaire changes, which include; the collection of detailed information about all qualifications completed (up to a maximum of 15) compared with only the 3 highest qualifications in 2005, and significant definitional changes to the 'work related training' topic.
For more information on the comparability of the 2009 SET with previous collections see Technical Manual: Survey of Education and Training, Basic and Expanded CURFs, Australia (cat. no. 6278.0.55.001).
INTERPRETABILITY
The Technical Manual: Survey of Education and Training, Basic and Expanded CURFs, Australia (cat. no. 6278.0.55.001) is a key reference document when using the CURFs. It includes survey objectives, methods and design; survey content; data quality and interpretation; output data items; and information about the availability of results; comparability with previous surveys; and the content of the CURF files. Further information can also be found in the Explanatory Notes section of Education and Training Experience, 2009 (cat. no. 6278.0).
ACCESSIBILITY
CURF microdata are not available to the public without special access being granted. All CURF users are required to read and abide by the Responsible Access to ABS Confidentialised Unit Record Files (CURFs) Training Manual. Application to access a particular CURF can be completed and submitted for approval by following the step-by-step guide at theHow to apply for Microdata web page. A full list of available CURFs can be viewed via the Expected and available Microdata.
The 2009 SET Basic CURF can be accessed on CD-ROM, in addition to being accessed through the Remote Access Data Laboratory (RADL) and the ABS Data Laboratory (ABSDL). The Expanded CURF can only be accessed through the RADL and the ABSDL.
More detail regarding types and modes of access to CURFs can be found on the CURF Access Modes and Levels of Detail web page.
Any questions regarding access to CURF Microdata can be forwarded to the Microdata Access Strategies Section at <[email protected]> or phone (02) 6252 7714.

This article based on work done by Ramuk on Linkstationwiki.org
How to use a USB cabled Palm-OS device as an external (20x4) character LCD display for your Linkstation using the PalmOrb emulator
USB LCD : These instructions are essentially for a USB LCD Display, a USB docking Palm-OS device can emulate a USB LCD interface so that no external adapter is needed. The same instructions could be used with some modification to add an LCD with the Articles/PPCSerialHeader
Contents
Abstract
This article is for people that want to add an LCD display to their Linkstation, but don't want to crack it open, and happen to have a USB cabled Palm OS device lying around.
Prerequisites
This article assumes that you have installed Projects/FreeLink. A 2.6 Kernel Articles/GeneralUpgradeTo26-Kernel has better USB support, but a 2.4 Kernel would probably work as well. For these instructions you will need a USB cabled Palm-OS Device.
Method
• Install PalmOrb on your USB cabled Palm-OS Device. The v1.1a4 version has the most font options for a (20x4) emulated LCD, there are several other versions available on the sourceforge site. It emulates a Matrix Orbital LK204-25 LCD.
Configure the PalmOrb app to use the USB Port Menu -> Options -> Serial:Device:USB
• Install and remove LCDProc using apt-get (this should take care of any dependencies) The Debian Stable Version only has the LCDd Daemon program but not the lcdproc client, so you'll have to install lcdproc from a tarball. Kind of an ugly solution to get the dependencies resolved, but it works:
apt-get install lcdproc
apt-get remove lcdproc
• Get the LCD Proc tarball and compile/install it.
wget http://lcdproc.omnipotent.net/download/lcdproc-0.4.5.tar.gz
tar -xvzf lcdproc-0.4.5.tar.gz
cd lcdproc-0.4.5
./configure
make
make install
........
[MtxOrb]
# Matrix Orbital driver
# Select the output device to use [/dev/lcd]
device=/dev/ttyUSB0
#device=/dev/usb/tts/1
#device=/dev/ttyS1
# Set the display size [20x4]
size=20x4
........
• Attach the USB enabled Palm-OS device and start the PalmOrb app. Do a dmesg of your linkstation; if things went well you should see lines like this at the end:
usb 3-1: Handspring Visor / Palm OS converter now attached to ttyUSB0
usb 3-1: Handspring Visor / Palm OS converter now attached to ttyUSB1
• Run the LCDd (LCDproc Daemon) and LCDproc client with some options to see if it works.
LCDd &
lcdproc C M X
• Hopefully you got some output on the Palm-OS device as an LCD. For other clients Google:lcdproc to see what other LCDProc clients you can find. Or just go here: LCDProc Site:Clients
What's the point?
PALM AS A TERMINAL untested: Enable terminal access with this command: getty -h -L ttyUSB0 9600 vt100, and use a terminal program like ptelnet
Well if you happen to have a USB enabled older Palm OS PDA lying around and want an external LCD display for the price of nothing, now you have it!
Shell Scripts
#!/bin/sh
# lcdmon.sh
# Kill any LCDd that are running first, Start the Daemon and
# fork it to the background. Then run LCDProc with the Time option and
# fork it to the background.
# You can run lcdproc -? alone to see what options there are.
# Run another client: netlcdclient which gives U/Dl speed
# You could run this script at startup.
killall LCDd
LCDd &
lcdproc T &
netlcdclient -i eth0 -a LinkSTN -d

Xiaochuan Zhang
Abstract
This paper generalizes research of university students’ political socialization as four issues, namely, the issue of formation of university students’ “political self”, the issue of a variety of transmission media for political culture, the pattern of university students’ political socialization and the mechanism of university students’ political socialization. It also summarizes and analyzes studies on these four issues in the recent years with an expectation to provide reference for further research.

Building a Notification
This lesson explains how to create and issue a notification.
The examples in this class are based on the NotificationCompat.Builder class. NotificationCompat.Builder is in the Support Library. You should use NotificationCompat and its subclasses, particularly NotificationCompat.Builder, to provide the best notification support for a wide range of platforms.
Create a Notification Builder
When creating a notification, specify the UI content and actions with a NotificationCompat.Builder object. At bare minimum, a Builder object must include the following:
For example:
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("My notification")
.setContentText("Hello World!");
Define the Notification's Action
Although actions are optional, you should add at least one action to your notification. An action takes users directly from the notification to an Activity in your application, where they can look at the event that caused the notification or do further work. Inside a notification, the action itself is defined by a PendingIntent containing an Intent that starts an Activity in your application.
How you construct the PendingIntent depends on what type of Activity you're starting. When you start an Activity from a notification, you must preserve the user's expected navigation experience. In the snippet below, clicking the notification opens a new activity that effectively extends the behavior of the notification. In this case there is no need to create an artificial back stack (see Preserving Navigation when Starting an Activity for more information):
Intent resultIntent = new Intent(this, ResultActivity.class);
...
// Because clicking the notification opens a new ("special") activity, there's
// no need to create an artificial back stack.
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
this,
0,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
Set the Notification's Click Behavior
To associate the PendingIntent created in the previous step with a gesture, call the appropriate method of NotificationCompat.Builder. For example, to start an activity when the user clicks the notification text in the notification drawer, add the PendingIntent by calling setContentIntent(). For example:
PendingIntent resultPendingIntent;
...
mBuilder.setContentIntent(resultPendingIntent);
Issue the Notification
To issue the notification:
• Get an instance of NotificationManager.
• Use the notify() method to issue the notification. When you call notify(), specify a notification ID. You can use this ID to update the notification later on. This is described in more detail in Managing Notifications.
• Call build(), which returns a Notification object containing your specifications.
• For example:
NotificationCompat.Builder mBuilder;
...
// Sets an ID for the notification
int mNotificationId = 001;
// Gets an instance of the NotificationManager service
NotificationManager mNotifyMgr =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// Builds the notification and issues it.
mNotifyMgr.notify(mNotificationId, mBuilder.build()); | v0 |

Berkeley County (or precinct) replaced the name of Perquimans County (or precinct) in 1680. Due to citizen objections to the name change, by 1681, or the mid-1680s Berkeley Precinct was changed back to Perquimans Precinct. Records of Berkeley County or Precinct are now found in repositories of Perquimans County, North Carolina.[1][2]

#7753 closed defect (duplicate)
plugin management: unable to activate plugin after aborted download
Reported by: e-blu@… Owned by: team
Priority: minor Component: Core
Version: tested Keywords:
Cc:
Description
Windows XP; Ubuntu 11.10
When clicking "cancel" while downloading a plugin (e.g. ImageImportPlugin which is larger and therfore taking longer than most others), the partially downloaded file remains in the plugin directory. Due to this, the plugin cannot neither be used (as it is incomplete) nor be downloaded again (as it is existing) from within JOSM without manually deleting the file in the plugin directory.
If possible, shouldn't cancelling the download remove the partially downloaded file from the plugin directory?

This kind of announces/advertisments would probably belong to the
maemo-announce list, if even there (I'm not sure about the policy,
the listinfo page states that "any announcement related to Maemo" but
that might be a little broad).

I'm pretty sure anyone subscribing to maemo-devel would already know that ;)

Vang Vieng (ວັງວຽງ)(also Vang Viang) is a riverside town in Central Laos.
Contents
Understand
NOTE: The majority of the bars from the start of tubing into the town are closed, and it is unknown when, or even if, they will re-open: further available are in the Vientiane Times. Tubing without the drugs and alcohol remains available.
Once little more than a bus stop on the long journey between Vientiane at the Thai border and the World Heritage Site of Luang Prabang, it has managed to become a destination in its own right. Still not much more than three streets and a bus station, the main attractions are the river, laid back countryside and cave-filled rock formations.
Many who have travelled around South East Asia have heard about tubing, an activity that dominates the town and its visitors. Originally opened up by hedonistic backpackers, the atmosphere of the town itself is one of lethargy by day and debauchery by night: tourists sprawl out in the pillow-filled restaurants, termed "TV Bars", watching re-runs of US sitcoms, Friends and Family Guy episodes until the sun goes down, and then party heavily until the early hours.
A couple of kilometres upstream, the pulsating music, drinking games and drug-fuelled debauchery of the increasingly lively riverside "tubing" bars starts at lunch-time.
NOTE: Be aware that roughly one tourist dies every month while jumping or tubing. Several more get severe injuries - every month, as there are many sharp rocks not visible under the water in many places along the river.
Do not jump at all if you are drunk.
It's very difficult to always predict where you will land in the water while jumping and there are almost always some rocks nearby!
Vang Vieng may have established itself as the exception to the rule that Laos doesn't have nightlife. It does have potential as a base for adventure tourism which attracts a few more sedate foreign sightseers. However, it can be considered a noisy "back-packer hell" and so those wishing to avoid noisy, selfish teenagers away from their parents for the first time and instead seek something Laotian would do as well to either use Vang Vieng only as a base to explore the surrounding countryside or avoid it all together.
Get in
Vang Vieng is on Highway #13 between Vientiane and Luang Prabang - by bus (road and bus conditions permitting) about 6-8 hrs from Luang Prabang, around 3-4 hr from Vientiane.
Highway #13 is a sealed two lane road that is slowly deteriorating. The road between Vang Vieng and Luang Prabang is mountainous and boasts amazing scenery. The road between Vang Vieng and Vientiane is flatter and less interesting.
By bus
Tickets for tourist buses and minivans can be purchased at almost every guesthouse and should include transport to the bus station.
VIP buses from Vientiane cost about 50,000 kip. Minivans leave Vientiane all day and cost in between 35,000-50,000 kip. The Express bus to Vientiane costs 60,000 kip (Feb 2011). Slower local buses to Vientiane without air conditioning run in the early morning (5:30AM-10AM) and cost about 40,000 kip for a 5 hour journey - you can board them either at the northern bus station or the bus stop south of the airstrip.
From Luang Prabang, VIP buses cost 150,000 kip and minivans cost 120,000 kip (June 2012). If you're susceptible to motion sickness you'll be much better off on the slower bus than the minivan.
Get around
From the bus station
From Vientiane, buses will drop you off either at the old airstrip (from the Vietnam war, it's now just a giant gravel pad) and the tourist buses will drop you in front of a hotel on the main street in town. The airstrip is directly behind the main street, so in either case there is no need to take a tuk tuk or cyclo if you plan to stay in the main area of town. The island and bungalows along the river are about a 10 min walk away. Buses to and from the North of Laos leave from the new bus terminal 2 km North of town. When leaving Vang Vieng, transport to the bus station is usually included in the price of your ticket.
Around town
Vang Vieng is so small that everything is easily reachable by foot. If you want to venture outside of town, bicycles are widely available and can be rented from hotels or local businesses. You should not have to pay over 10,000 kip for a day's rental.
Motorcycle rentals are also widely available. It's quite easy to rent a motorcycle from a local business for only 40,000-60,000 kip. Petrol may not be included in the rental fee, so check before paying. If not included, it's an extra 10,000 kip (Nov 2012). Always check the details of the contract. At some places you will have to sign a contract which makes you responsible if something breaks or fails to function, even if it's normal wear and tear. If riding out of Vang Vieng to the surrounding villages, be very careful of buses, minivans and trucks, and take extra precautions against the poor road conditions. Gravel, potholes, mud puddles and other hazards litter the road, so it pays to keep your eyes on the road and not on the mountain scenery. Also you are not allowed to go out of the Vang Vieng district, so don't count on renting a bike here to go on a longer tour of the district.
Several tuk tuks are also scattered around town. 10,000 kip per person will be plenty to get to anywhere within Vang Vieng - it's also the price you'll pay to get to the tubing bars irrespective of how many other people are on board. It's better to sort out exact change with fellow passengers as tuk tuk drivers are notorious for giving incorrect change.
To rent a tuk-tuk for the day costs about 130,000-150,000 kip.
See
The town itself offers no real attractions, but the row of limestone karst mountains across the river provides a stunning backdrop and is the setting for some impressive caves.
• Tham Poukham - Blue Lagoon, (7 km west from town, maps provided where you can rent bicycles, accessible by mountain bike or motorbike. Be careful along the way, in recent years a number of imposters have shown up, all claiming to be the 'blue lagoon'. Keep to the main road and you should be OK). 8AM-6PM. A spring fed lagoon at the bottom of "Golden Cave". Nice place to relax, swim and play on the rope swing. The waters are inhabitated with a few hundred carp that will eat locally sold fish food out of your hand. The cave above requires a modest 100 m climb up a makeshift bamboo ladder. Once inside, there is a short walk to the Sleeping Golden Buddha and glimmering stalactites about 300 m further inside. 10,000 kip entry and 10,000 kip to rent a head-torch, mandatory if you go deeper into the cave than the Buddha (check the battery in advance). Guides for the cave advertised at 50,000 kip but this is probably negotiable. Guides are recommended as finding the best way to climb through the cave can be quite difficult.
• Padeng cave and Ring cave, (cross a footbridge over the river, follow the signs and white flags (garbage bags) on sticks through the field). Across the river a 1.5 km path marked by white flags cuts through the fields towards the limestone mountains. The smallest hill has very rickety ladders (which can be dangerous) to aid in climbing to the top. Halfway up the mountain is a cave. Another 1 km along the path past the mountain goes through a small forest and arrives at a cave. A few sleepy Laotians guard the cave's entrance and a hand painted sign says that guides are mandatory. It costs extra to go to the lagoon in the cave, and the guides will let you know that "tipping extra is ok". 10,000 kip for the hill, 15,000 kip for the cave, 30,000 kip to go to the cave lagoon.
• Xang Cave, (on the south end of the main road. Turn right at the sign to Jam Mee Guesthouse). Decent cave but not worth the 15,000 kip entrance fee plus 2,000 kip per person/3,000 kip per motorbike bridge crossing fee. The cave is well lit and has stairs running throughout that makes it an easy self-guided tour. One part has a really nice view of the farms surrounding the city. If you've been to other caves it's really not worth it.
Do
Vang Vieng bar with rope swing on tubing route
• Tubing, (There is an office in downtown Vang Vieng that now organizes all tube rentals. It's pretty easy to find--just ask around. They will rent you the tube and organize transportation up the river a few miles.). From around midday to 2PM is reasonable to go because earlier everyone else would be still asleep. Look at the magnificent view of the mountains rising directly beside the river. Many beer and other pit stops along the way. Also, try the diving stop and the swing. Some dry bags may not be of the best quality & so cameras can get ruined. To get the deposit back tubes have to be returned by 18:00. In winter temperatures fall from 16:00, so start back early. Ride at least one rapid before starting the party to avoid disturbing guests visiting the Organic Farm. The party scene has taken over and the owners use large loudspeakers, effectively blocking out any singing of birds. Beware of tubes getting stolen while stopping at bars, you may lose your deposit and the ride down. Tubes get stacked up at each bar so keep an eye on how many are left, especially at the first few bars where lots of people arrive without their own tube. If you're not used to drinking stromg alcohol: stick with beer, and for reasons of safety & common sense consider avoiding alcohol if entering the water. The amount of alcohol in buckets can be high, and the effect can kick in suddenly; you won't be the first one to be too drunk to make your way back on the river. During rainy season there is more water in the river and eye infections are common. 55,000 kip for the Tube + 60,000 kip deposit.
• Lao-style steam sauna.
• Kayaking the river. This covers the same part of the river as tubing (and a more untouched part further upriver). Kayaking includes lunch and different caves. Some of the caves takes more than an hour to walk through, with bats and other animals.
• Watch movies. The US TV-series Friends is shown at many restaurants, and seems to be very popular with the younger party crowd.
• Uncle Toms Trails, 2 (On the west side of the river (the path to the blue lagoon )), 856 (0)2029958903. Uncle Toms is a dirt bike tour operator offering tours of the beautiful trails around Vang Vieng. All new bikes, 125cc four stroke trail bikes. Prices are US$30 for a half day or US$55 for the full day.
• High swings. Playing on the very high swings over the river and sliding on a slide. Be careful: perforated eardrums, broken ribs, foot injuries and permanent hearing damage are common injuries, and deaths are not unknown. The local hospital is not equipped to diagnose or treat these serious injuries - Vientiane has the closest, if spartan, ENT facility but no English speaking specialists, so you may have to travel to Udon Thani for treatment. You might have to rely on other tourists for rescue. Most of these swings and slides have been taken down.
• Organic farm, 3 km north of Vang Vieng, close to where the main tubing run starts, is an organic farm offering volunteering opportunities. It is noise-free until about 11:00 and again when the last revellers return to town around 18:00. They teach the village children, build mud brick buildings, learn/teach farming, eat organic food and go to sleep at 22:00. The farm has also a kitchen and sells organic food. The organic farm has dormitory (30,000 kip ), budget and more luxurious rooms for rent.
• Rock climbing, [1]. There are walls suitable for first timers and professionals. The established climbing outfits in town are Adam rockclimbing and GreenDiscovery. A new shop opened in 2012, Central Climbers, managed by seasoned climber Nom.
• Hot Air Ballooning. A flight over the surrounding countryside with stunning views.
• SAELAO Project, (Nathong Village, 7km outside of Vang Vieng, near of Poukham Cave and the Blue Lagoon), 020 2292-8630, [2]. SAELAO project is trying to set an example of sustainable development for local people. There are different projects including building, organic farming and teaching English to the locals. They are always looking for volunteers, but if you don't have time to volunteer you can visit their restaurant to have lunch & learn about the project.
• Vang Vieng Paintball, Tham long road (Behind Fluid Bar, about half way to start of tubing), [3]. When you think of Vang Vieng, you think of tubing and drinking. Vang Vieng Paintball brings the first and only paintball field to Vang Vieng, located next to the river with spectacular views of the jungle and the mountains. Western run, you are guaranteed the quality and satisfaction you would expect from back home while saving well over half of what you would normally pay. Full service bar and a kitchen for all your needs. Any age welcome, please make sure to bring proper footwear, overalls will be supplied. $15.
• FruitFriends, ([email protected]), [4]. A transparent organisation providing volunteer the opportunity to immerse in Lao society. FruitFriends profits are used to execute community activities, building schools, set-up youth movement, English classes, ... If you want to participate in a transparent organisation respecting its staff and following the law on labor FruitFriends is the place to be. More information on their website www.fruitfriendslaos.org
Buy
The small shops scattered throughout Vang Vieng sell the standard assortment of snacks, trinkets, sunglasses, and bathing suits. The majority of tourists seem to leave with at least one T-shirt, vest or dress with "In the Tubing - Vang Vieng" emblazoned on it.
Prices for tourist packages are quoted in both kip and US dollars. Restaurants, hotels, and pretty much everything else is priced in kip. Most places will accept kip, US dollars and Thai baht for larger purchases.
There are several ATMs that now take all major credit cards but are known for running out of cash. Some tourists have reported only being able to use cards on the Maestro (Mastercard) network.
The Lao Development Bank changes money at good rates and processes cash advances. BCEL will also do cash advances on credit cards.
Eat
The numerous TV restaurants are interchangeable and all have a similar theme. When it comes to wifi some offer it free, others sell access. Others offer access only at certain times only. They all have similar menus. A selection of Lao, American, Italian, Chinese and Thai food is normally fresh but often of indifferent quality and poorly executed. Small serves average 20,000-45,000 kip.
For quick eats and late night snacks, numerous pancake and sandwich stalls dot the streets. But be careful, food hygiene may have been compromised by being in the heat all day and your gastro-intestinal system may react accordingly. The street running next to the river just to the west of the tube rental office has a few vendors selling large chicken and pork kebab skewers for 5,000 kip each.
• Mister Potato, (in the small street along the hospital) is a food cart with tables and chairs to sit. They serve fresh homemade beef sandwiches with potato twists and drinks. The set menu is good value..
Be aware that many restaurants offer "happy" shakes and pizzas: food or drink with the words "happy", "special" or "ecstatic" will contain marijuana or magic mushrooms
• B&P Restaurant & Bar, (in between Babylon guest house and Organic farm restaurant). Lao, Thai and Western cooking. Homebaked applepie with vanilla icecream accompanied with an espresso, cappuccino or a big pot of mulberry tea. Very cosy, clean and nice looking restaurant. Free wifi for customers. Friendly staff with a Lao/Dutch management.
• Jungle Bar, (turn left at the fork by the tubing centre, beside TCK Tours). Good quality food, relaxed environment with cheap meals. Does not play Friends or Family guy. The friendly owner, Jackie, serves good fruit shakes, pizza and Pad Thai.
• Q Bar and Restaurant, [5]. Food and drinks from as little as £1. Steak+drink for 30,000 kip, curry+drink 15,000 kip.
• Nisha Indian Food, only open from 2PM. Serves great Indian food.
• Organic Farm Cafe. Original and interesting menu. Deep-fried mulberry leaves in honey for 15,000 kip. Goat cheese sandwich for 30,000 kip.
• Peeping Som's Bar and Restaurant, Main Rd (just past Wat Kang, next to Chilllao Guesthouse). A small menu offering a change from most other restaurants in town. The English chef focuses on the quality of dishes, preferring to offer a few very well executed meals. Lao drinks such as Lao Hai, Flavoured Lao Lao also on offer.
• Pan's Place Guesthouse, (Pan's Place Resteraunt), (on the main street), Vang Vieng (300 Meters South of the centre), 023 511484, [6]. 7am - 11pm. Western-style menu, including: All day English Breakfast, Spaghetti Bolognase, Beef Goulash, Cottage Pie, fresh fruit shakes, snacks & drinks. Helpful & friendly staff under Kiwi/Lao management.
• The Meeting Place, 047 Ban Vieng Kaew (end of the main street, 3 blocks from city centre, beside Laos Haven Hotel & Spa), +856 23511900. 11am - 10pm. Newly opened restaurant that serves Thai, Lao & Western cuisine. A small, 20-seater establishment. Phad Thai, Spring rolls, Larb and Som Tum(green papaya salad) are their more specialised dishes. USD 3 onwards per pax.
Drink
Beerlao is available everywhere in Vang Vieng, but the drink of choice is a cheap plastic bucket filled with liquor and soft drinks. A bottle of Tiger Whisky costs the bar 10,000 kip, so around a third of a bottle goes into your bucket, normally with a choice of 7up or Pepsi, lime and Redbull.
Tubing area
The ramshackle wooden bars in the first stretch of the tubing area are too numerous to single out any individual ones and heave with people in the early afternoon even though many of them haven't rented tubes and some of them have no intention of even going in the water - there are plenty of pathways and bridges to get around. Lie on plastic mats by the river and drink Beer Lao, or dance the day away on an outdoor dance floor.
Westerners employed by the bars for food and accommodation hand out free shots and organise drinking games to encourage you to stick around; many will also offer promotions to encourage you to their visit twin bars in town later in the evening. The competition among the night bars is so fierce that the deals are often genuinely pretty amazing, and if you time it right you can go from bar to bar for free buckets and cheap deals.
Too much alcohol or "special" or "happy" shakes which can contain cannabis, magic mushrooms or any manner of substance are not a good idea if you plan on going back in the river.
In town
Beer and buckets are available all around Vang Vieng in bars covered with Christmas lights (including all the "TV restaurants") and the buckets are usually very strong because Lao whisky is cheaper than soft drinks. There's no shortage of choice but a distinct lack of diversity, especially if you're looking for live music.
• The Kangaroo Sunset Bar, Next to New Bridge, River Road., +856 20 7714291. Australian owned and claims to offer the coldest beer in town. Now run by an English guy and Lao woman. Has some things you cannot get anywhere else such as Marmite, Vegemite, Yorkshire tea, Branston pickle and chilli con carne. Beautiful view.
• Kiwi Sports Bar, In between the hospital and Pan's Place Guesthouse, +856 2028779796. The cheapest beer in town. Play your own music. Free pool, dartboard, internet, whisky and sports on a 60" LCD. Excellent variety of Italian and Lao food. Also has mountain bikes for rent.
• Q-Bar, (on the main street). A club environment. Depending on the revolving staff of westerners they play Dnb, dubstep and pop. Open for food all day, and closes between 12 midnight-1AM, depending on the numbers.
• The Rising Sun (The Irish bar), +856 20 7928266 (), [7]. The only Irish pub in Vang Vieng. Regular live music, 2 free pool tables upstairs and downstairs and 3 TVs showing live sport. Cold beers and homemade pies.
• Sakura, (In the village centre), +856 20 6506993 (), [8]. Is a step above the standard Friends and Family guy bars. They have a projector, with a fairly solid library of both Hollywood and art House films, although you have to be lucky or go in with a sizeable group to get your first choice. They also offer dice roll bucket deals, if you're lucky you win a free bucket. Free wifi here but only available from 9AM-8PM.
The Island
For serious drinking, the bars referred too collectively as The Island, reached via some ramshackle bamboo and wood bridges are where most of the tubers end up after a day on the river, particularly after the bars in town start to close. The sandwich pancake pushers hover in a long line as people stumble over the bridge, waiting to prey on drunken western tourists. But be aware of trying to buy eye drops for conjunctivitis around this area. Stories abound of people being drunkenly extorted as much as 5x the normal price for conjuntivitis treatments.
• The Bamboo bar, stands out a bit from the rest and offers mojitos (also alcohol free) served in bamboo with bamboo straws whilst watching the late tubers come in and watching the sometimes spectacular sunsets and thunderstorms over the mountains. Located on the island in the river at the end of the tubing surrounded by bamboo. A sauna is being built for the high season and vegetarian buffet is ready after one hour on demand by a larger group. Cheaper bars close by also offer drinks and food.
• Limbo bar, so named for fire limbo stays open very late.
• Rock bar, offers a change in music.
• Joker Bar and Sunset Bar, stay open the latest.
Sleep
There are now a couple of halfway-decent midrange "hotels" and attempts at boutique style residences.
Generally though, double rooms go for US$6-15, make sure you see the room (and bathroom!) before paying. More local, low-key (which is pretty low-key in Vang Vieng to start with) places are by the market and more shiny set ups are on the main road. The party crowd tend to advocate a bungalow on the island, but expect it to be too noisy if you want to sleep during the night.
Most guesthouses have large TV-viewing areas, practically coated in the Southeast Asia signature triangular cushions, where they serve food. But be forewarned - you'll be hard pressed to find a place screening something other than the US sitcoms "Friends" and "Family Guy".

Stay safe
Thousands of tourists pass through Vang Vieng without incident every year, but the combination of outdoor activities, drink and drugs still makes it one of South East Asia's most dangerous destinations for travellers.
Even the town's main street can injure the unwary traveller: you'll need to watch out for the large holes in the pavement through to the drainage ditch below as they are not fenced off.
The medical care available in the town's hospital is rudimentary at best - for serious injuries you'll want to go to Vientiane, or better still, Thailand.
Watersports and alcohol
Floating downstream at a sedate pace in an inflated rubber tube shouldn't be a dangerous activity, provided you leave enough time to get back before darkness falls.
What raises the danger level is the bars offering a combination of strong alcoholic drinks and high platforms to jump from.
Whilst you may find that risk reduced somewhat by the dismantling of some of Vang Vieng's infamous ziplines, swings and slides following recent deaths, you're still going to have use your common sense. If you want to jump into the river, be very careful about where you do so - the Nam Song isn't very deep except where the bar staff have cleared rocks from the river bed. Don't even think of pushing others in: at least one person has died that way.
Needless to say, if the alcohol or drugs you've consumed may impair your ability to swim or climb out, don't enter the water, even on a rubber tube. Remember whisky buckets can be deceptively strong and their effects can kick in very quickly.
The river current is strong in many places - even those who are sober should avoid sapping their strength by swimming against it. It should be easy enough to swim across to shallower water instead.
Drugs
Historically accepted drugs, such as marijuana, mushrooms and opium are freely available in many bars and restaurants around town. The majority of bars have 'magic menus' with most of these things on. Consuming these drugs on the premises is fairly safe, although drugs are illegal in Laos and nothing is totally safe.
Southeast Asian 'crystal meth' is known as yabba and is available in both pill and smokeable forms. Formerly legal in Thailand as a way for longhall truck drivers to keep awake. Yabba is an epidemic due to its highly addictive qualities. Manufactured locally, the drug can be cut with any number of substances.
Aside from the drugs already mentioned it is inadvisable to attempt to purchase any other substances not freely available on the 'magic menus' around town. The dangers of most drugs should be well known to visitors, and additionally there is also a police presence. Plain-clothed policemen frequently take unsuspecting tourists to the local police station for smoking a joint. The usual outcome of this involves having your passport seized until you cough up a hefty fine typically of 3-5 million kip. Once the fine is paid however the matter is generally taken no further and the passport returned; however, the punishment will depend on the officer you are dealing with. Several local policemen are friendly with restauranteurs who sell opium, mushrooms, cannabis and yaba. Customers are not harassed at these establishments: the police wait until they leave. Some of the same police own guesthouses near the island. Never surrender your passport if you can help it, and often the best way out of the situation is simply to pay.
Medical Issues
A minor annoyance around Vang Vieng (refered too by locals and long time residents as the Vang Vieng plague) is conjunctivitis, or 'Pink Eye'. This is a viral, and sometimes bacterial, infection which can be caught from the river or other tubers. The onset of pink eye is often felt as an unnatural tiredness, and inability to properly fully open your eyes. If you sense this, or have been sharing buckets with people with pink eyes or wearing sunglasses at night, the best thing to do is shell out for eyedrops as soon as possible to prevent the onset. If this should happen late at night, be aware that eye drops alone should cost a maximum of 20,000 kip. Some of the late night pharmacies attempt to extort tourists, charging up to 5x the normal price for eyedrops.
As well as eye drops, general antibiotics are available from any pharmacy. In some cases eye drops will cause an intense stinging sensation, this can be soothed with an eye bath formula also available at pharmacies. Of course the sensible solution would be to rest your eyes and ease the drinking, but Vang Vieng's non-stop party atmosphere makes this a hard option for most. Should your pink eye last longer than a week you should probably seek proper medical advice, and stop drinking all that Tiger Whisky to give your body time to heal.
Taxiboat
When tubing home late, taxi boats may offer to take you back for around 10k each. Howeber, they may just take you to somewhere else, stop and refuse to continue. If you don't want to pay the tuk tuk, the only way to get home is to walk.
Get out
• The adventurous can make their way Vientiane down the river by kayak. The trip should leave in the early morning, placing you in the capital by 6PM. For your belongings, dry bags are available or you can opt to place them in the accompanying van which will take them along and carry you at least part of the way. Expect to pay 170,000-220,000 kip
• You can book trips all the way to Bangkok (via Vientiane) but since you'll change mode of transport at least once anyway it's just as easy to arrange this trip at your own pace.
• Buses to Vietnam are notorious for taking even longer than expected and being a really unpleasant experience.
• Buses also go directly from Vang Vieng bus station to Udon Thani bus station. Bus departs at 9.30am (more like 10am) and schedulied to arrive at 5pm, though this may be on conservative. 100,000 kip for tickets if bought at the bus station.

Although the Australian Capital Territory had the highest average income from Wages and salaries in each year from 2001-02 to 2005-06, Western Australia recorded the highest average annual growth rate (5.3%) over this five year period. The average annual income from Wages and salaries in Australia in 2005-06 was $42,250 with an annual average growth rate of 4.2% between 2001-02 and 2005-06.
The ten SLAs with the highest average Wage and salary income in 2005-06 were all located within their respective capital city Statistical Divisions. A high proportion of Wage and salary earners in these SLAs were in Manager and Administrator or Professional occupations.

MEDIA RELEASE

Embargoed 11.30 am (AEST)
60/2007
Many employees are working extra hours
Over a third (37%) of the 8 million employees (excluding owner managers of incorporated enterprises) in November 2006 usually worked extra hours or overtime in their main job, according to figures released today by the Australian Bureau of Statistics (ABS).
Of the 2.9 million employees who worked extra hours or overtime, 43% usually worked paid extra hours only, 48% usually worked unpaid extra hours only and 9% usually worked both paid and unpaid extra hours.
There were 1.4 million (17%) employees who usually work shift work. Approximately one in five (21%) employees aged 15-19 years reported they usually work shift work, and 20% of those aged 20-24 years. A slightly higher proportion of men work shift work (18%) than women (16%).
Other findings from the Working Time Arrangements, Australia survey include:
• 60% of the 8 million employees 'did not have any say in their start and finish times'
• 72% could choose when their holidays were taken
• 38% were able to work extra hours in order to take time off
• 23% had earnings which varied from one pay period to the next
• 36% had hours that varied weekly or they were usually required to be on call or standby.
The Working Time Arrangements Survey also collected some information on the employment characteristics and working patterns of all 8.6 million employees (including owner managers of incorporated enterprises). Almost all (8.1 million) of these employees held only one job, and nearly half a million (493,900) held more than one job. One in five multiple jobholders worked 7 days a week, compared with 4% of single jobholders. The majority (56%) of multiple jobholders usually worked some hours between 7.00pm and 7.00am compared with 28% of single jobholders.
Media note:
Owner managers of incorporated enterprises are legally defined as employees but some of their employment characteristics and working arrangements differ from other employees. Some information is not collected from owner managers of incorporated enterprises for this reason.
Further information can be found in Working Time Arrangements, Australia, November 2006 (cat. no. 6342.0).

Yao Zheng, Eric Osmer
Abstract
This paper investigates the link between exchange-traded funds (ETFs) and the macroeconomy. Using a nonlinear approach, we find that the one-month T-bill rate, default risk premium, change in the money supply, growth of industrial production, and dividend yield have predictive power with regards to the return on ETFs. Moreover, the predictive power of these macro variables depends both on the underlying volatility state as well as the focus of the ETF. Additionally, our evidence suggests that ETFs have asymmetric risk exposure across expansion and recession states.

Abstract
Introduction
Hemophilia A is an X linked recessive hemorrhagic disorder caused by mutations in the F8 gene that lead to qualitative and/or quantitative deficiencies of coagulation factor VIII (FVIII). Molecular diagnosis of hemophilia A is challenging because of the high number of different causative mutations that are distributed throughout the large F8 gene. Molecular studies of these mutations are essential in order to reinforce our understanding of their pathogenic effect responsible for the disorder.
Aim
In this study we have performed molecular analysis of 28 Tunisian hemophilia A patients and analyzed the F8 mutation spectrum.
Methods
We screened the presence of intron 22 and intron 1 inversion in severe hemophilia A patients by southern blotting and polymerase chain reaction (PCR). Detection of point mutations was performed by dHPLC/sequencing of the coding F8 gene region. We predict the potential functional consequences of novel missense mutations with bioinformatics approaches and mapping of their spatial positions on the available FVIII 3D structure.
Results
We identified 23 different mutations in 28 Tunisian hemophilia A patients belonging to 22 unrelated families. The identified mutations included 5 intron 22 inversions, 7 insertions, 4 deletions and 7 substitutions. In total 18 point mutations were identified, of which 9 are located in exon 14, the most mutated exonic sequence in the F8 gene. Among the 23 mutations, 8 are novel and not deposited in the HAMSTeRS database nor described in recently published articles.
Conclusion
The mutation spectrum of Tunisian hemophilia A patients is heterogeneous with the presence of some characteristic features.

Introduction
Hemophilia A is an X linked hereditary bleeding disorder which results from a deficiency or abnormality in FVIII activity. The FVIII protein is composed of structural domains represented as A1-A2-B-A3-C1-C2 and is activated after the dissociation of the B domain. A large and heterogeneous spectrum of mutations has been identified in the F8 gene [1]. They include partial or complete gene deletions, duplications, large insertions, splice alteration, frameshifts as well as nonsense and missense mutations (FVIII mutation database: http://hadb.org.uk webcite). The most common mutations in severe hemophilia A are the intron 22 inversion mutations which occur in 45-50% of severe hemophilia A patients and the intron 1 inversion mutation which has been reported to be present in approximately 5% of patients with severe phenotypes [2,3]. The development of inhibitors in patients presents a major complication of treatment with FVIII, especially in patients with severe forms of hemophilia A [4]. The Hemophilia treatment centre of Aziza Othmana Hospital in Tunisia follows 143 hemophilia A patients. 72 of these patients have been diagnosed with severe, 49 with moderate and 22 with mild hemophilia A.
In a previous study we have determined the haplotype frequency in Tunisian hemophiliacs A concerning only single nucleotide polymorphisms (SNPs) [5]. Our aim in this study has been to identify the molecular genetics of hemophilia A patients for the first time in Tunisia. The characterization, molecular analysis and spectrum of these genetic alterations are reported in this paper.
Patients and methods
Patients
28 patients with hemophilia A from 22 unrelated families were included in this study. At the time of the study their age ranged between 4 to 38 years. 19 patients had severe form, 5 had moderate form and 4 had mild form of hemophilia A (Figure 1). All the patients gave informed consent for molecular studies.

Molecular genetic analysis
DNA was extracted from whole blood samples using a phenol chloroform protocol. Severe hemophilia A patients were first screened for intron 22 inversion. Negative patients were then tested for intron 1 inversion. Intron 22 inversion was detected using LD PCR and confirmed with southern blot as described [6]. Intron 1 inversion was performed using the Bagnall’s protocol [7].
PCR amplification was performed for mild, moderate and severe hemophilia A patients without intron 22 or intron 1 inversions. The coding sequence of F8 gene was divided into 33 amplicons (200-480 bp). Exon 14 was divided into 8 fragments for PCR amplification and the other exons were amplified as unique fragments. Primer sequences, annealing temperatures and the size of PCR fragments are available from the corresponding author, on request. Mixtures of patients and wild type DNA were screened by denaturing high liquid performance (dHPLC) on a WAVE DNA Fragment Analysis System (Transgenomics, San Jose, USA). All large deletions were defined as a consistent absence of PCR amplification products. Altered profile revealed by dHPLC were then sequenced in both strands using ABI Dye Terminator Cycle Sequencing (Perkin-Elmer Applied Biosystems, Foster City, CA, USA) and analyzed using a capillary sequencer Genetic Analyser ABI PRISM310 (Perkin-Elmer Applied Biosystems, Foster City, CA, USA). Mutations were confirmed by a second PCR and sequencing. Results were analyzed using BLAST (http://www.ncbi.nlm webcite. nih.gov/blast) program in comparison with the wild-type F8 gene sequence. Mutation nomenclature was given according to HAMSTeRS as well as in parentheses according to the international recommendations for the description of sequence variants on the Human Genome Variation Society (HGVS) website (http://www.hgvs.org webcite).
Analysis of missense mutations
All identified F8 mutations were compared to those described in the HAMSTeRS database (http://www.HAMSTeRS.ac.uk/ webcite). PolyPhen software (Polymorphism Phenotyping) was used to perform the sequence alignment of the homologous FVIII from four mammalian species (human, murine, canine and pig) and to predict the possible impact of an amino acid substitution on the structure and function of FVIII. The 3D structure of FVIII was visualized using the PyMOL Molecular Graphics System (http://www.pymol.org webcite) [8].
Result
In this study, 28 hemophilia A patients from 22 unrelated families were investigated. In total we identified 23 different mutations, which included 5 intron 22 inversions, 8 substitutions, 6 insertions and 4 deletions identified in 4 severe hemophilia A patients (Figure 2, Tables 1 and 2). Among the 23 different mutations, 8 are novel mutations and have not been described in HAMSTeRS database or reported in recently published data. Of these novel mutations, 6 occur in severe hemophilia A patients (del exons 1–13, intron 22 inversion (18 kb, 15.5 kb and 14 kb), p.1595(1614)DfsX40, p.12(31)LfsX11, p.C179(198)R and p.N784(803)N) and 2 occur in moderate hemophilia A patients (p.727(746)SfsX7 and p.G520(539)R).

Analysis of the two novel missense mutations p.C179(198)R and p.G520(539)R using the PolyPhen Software suggested both mutations to be considered as structurally damaging. Further analysis, mapping the substitution sites on the 3D structure of FVIII, show that both of these mutated residues are involved in interaction that can be considered important for the structural integrity of the mature FVIII protein. Residue C179(198) forms a disulfide bond with the residue C153. The mutation p.C179(198)R disrupts this disulfide bond formation, and thereby most likely leads to destabilization of the A1 domain (Figure 3). The second novel mutation p.G520(539)R is located in the interface between the A1 and A2 domains. Substitution of this neutral glycine with a charged arginine probably disturbs the interactions in this interface and destabilizes the interaction between the A1 and A2 domains (Figure 3).

Discussion
We report the first molecular study performed in Tunisian hemophilia A patients belonging to Hemophilia Treatment Center of Aziza Othman Hospital. Our cohort consists of 28 patients from 22 unrelated families. Despite the limited number of our cohort, the novel mutations occur with a significant frequency (34%) indicating that our patients have a specific mutational profile in comparison with previously reported data. Each studied family was found to have its unique mutation except for one. Among the 18 identified point mutations 9 were located in exon 14, the largest exonic coding sequence of the F8 gene. The correlation between genotype/phenotype was assessed for the identified mutations in order to clarify the effect of mutations on the phenotype and to compare our data with previously reported data.
Severe hemophilia A patients
Inversions (5)
In the 19 patients with severe hemophilia A, intron 22 inversion was identified in 7 patients (36.84%) belonging to five different families, while no family present intron 1 inversion (0%). This result indicates that the intron 22 inversion, which is reported in severe hemophilia A in the general population with a frequency of 45%-50% [9], is less frequent in our patient cohort. The same tendency was found for the intron 1 inversion, which is reported with a frequency of 5% [10]. When we compare our findings with previous data from other Arab countries the frequencies of these 2 inversions are lower in our patients [11-14]. This result shows that our patients have a specific genetic profile which is confirmed by other molecular studies concerning our country [15]. Nevertheless, this data must be confirmed with a larger number of studied patients.
Among the identified intron 22 inversion types, the type I inversion was the most frequent in our patients (families 10, 11 and 12), which correlates with what previously has been reported in the literature [16]. The type II inversion was identified in one patient (family 9) and a novel atypical pattern (family 8) with 3 bands (18 kb, 15.5 kb and 14 kb), since the amplification of exons 22 and 23 gave the expected size this atypical pattern may be explained by a deletion of 2 kb in the INT22-h1 or in the INT22-h3 homologous regions (Table 1).
Insertions and deletions (8)
In our cohort of severe patients we identified 7 frameshift mutations (Table 2). All of them are associated with very low or undetectable FVIII:C in plasma leading to a severe phenotype as expected, since frameshift mutations resulting from insertions or/deletions in most cases lead to severe phenotypes [17]. The new large deletion spanning exons 1-13 was found in one patient with severe hemophilia A and was associated with development of inhibitors (family 4).
Substitutions (3)
We identified 3 substitutions in 3 unrelated families with severe hemophilia A (Table 2), among these the novel mutation p.C179(198)R, which occurs in exon 4 within the A1 domain (family 5). In the encoded protein this mutation substitutes a conserved cystein residue and disrupts the disulfide bond formation leading to destabilization of the A1 domain. The severe phenotype associated with this mutation is in accordance with previously reported genotype/phenotype correlation. For instance, the mutation p.C179(189)G, which is also associated with a severe phenotype, is reported twice in HAMSTeRS [18]. Previous studies have also highlighted that mutations of conserved amino acids in FVIII frequently are associated with a severe phenotype [19,20].
The second novel mutation, p.N784(803)N, is a silent mutation identified in one patient with severe hemophilia A (family 22). This silent mutation has no effect on the mature FVIII protein structure, but it might play a role in the expression levels of the protein, such as other silent mutations which have been recently identified [21]. To confirm this hypothesis we need to screen this point mutation in healthy individuals in order to exclude that it is not associated with a SNP, since it is not reported in the HAMSTeRS data base or in recent identified SNPs [22]. The exact effect of this mutation remains elusive and will be of interest for future studies to reveal. The finding that the mutation p.L7(26)P identified in family 17 is associated with a severe phenotype is in accordance with previous findings, which have shown that the same mutation causes a severe phenotype [23].
Inhibitor development
The type and location of the F8 gene mutation is an important determinant of inhibitor development in patients with severe hemophilia A. In a recent study, nonsense mutations and large deletions were shown to be associated with a higher risk of inhibitor development than intron 22 inversion, small deletions/insertions and missense mutations [24]. In our cohort no nonsense mutation was identified and only one patient with a large deletion spanning the exons 1–13 developed inhibitors. None of the patients with insertions/small deletions or missense mutations developed inhibitors. The low incidence of inhibitor development in our cohort (1/28) and (6/143) in total for all patients followed in Hemophilia Treatment Center [25] may be explained by the low frequency of nonsense mutations and large deletions in our cohort. In order to confirm this hypothesis we need to increase the number of the investigated hemophilia A patients in our study.
Moderate hemophilia A patients
Insertions (2)
The novel insertion c.2236-2237insT and the previously reported insertion c.3870-3871insA identified in family 7 and 20 respectively (Table 2), are due to insertions of a ‘T’ nucleotide in the stretch of 3Ts at codon 727(746) and of an ‘A’ nucleotide in the stretch of 9As at codon1271(1290). Insertions in the stretch of poly A nucleotides in exon 14 of the F8 gene are the cause of the moderate clinical severity in some cases [26,27]. Accordingly to these reported data, we can consider that also the new insertion of T in the stretches of poly T can be associated with moderate phenotype in our patient.
Substitutions and splicing site mutations (3)
The novel p.G520(539)R mutation associated with the moderate phenotype is located within the A1 domain and is part of the A1-A2 domain interface. Reported mutations in HAMSTeRS from position 516(525) to 521(540) located at A1-A2 interface are all associated with moderate or mild phenotypes http://www.HAMSTeRS.ac.uk/ webcite, [28]. Studies of residues involved in interaction at the A1-A2 domain interface have showed that reducing the charge and increasing hydrophobicity at this interface yield FVIII with improved stability [29,30]. Thus, the mutation p.G520(539)R, which increases the charge at the A1-A2 interface, most likely has the opposite effect and leads to destabilization of the protein. The reported missense mutation p.G479(488)R, which is associated with a moderate phenotype in our patients, is described in HAMSTeRS with mild moderate or severe form [20]. The splicing site mutations are often associated with a severe phenotype [31]. In contrast, the unique identified splicing mutation (ag/GGC > ac/GGC) in our study, which interferes in the splicing process resulting in the skipping of exon 15, is associated with a moderate phenotype (Table 2).
Mild hemophilia A patients
Substitutions (2)
The mutation p.A704(723)T is reported 9 times in the HAMSTeRS data base, in 5 cases it is associated with the mild form which is in accordance with our result (Table 2). On the other hand the p.L547(566)F has previously been reported in one severe patient while in our study it is associated with a mild form (Table 2). The discrepancy between mutations predicted to be responsible for severe, mild or moderate forms may be explained by the intervention of other hemostatic factors which can modify the clinical severity of hemophilia [32].
Conclusion
We report here the first molecular analysis of causative mutations in Tunisian hemophiliac A patients. In total we have identified 23 mutations including 8 novel mutations. In the future we will continue this study on patients from our Hemophilia Treatment Center in order to reinforce our understanding in the molecular defect of hemophilia A in Tunisia and to set up counseling genetic and the prenatal diagnosis for Tunisian families with hemophilia A.
