3A670964557.jsonld | Synthesis, characterization, antitumor and antimicrobial activities of heterocyclic transition metal complexes | Transition metal complexes play a crucial role in antitumor therapy. Complexes of platinum, ruthenium as well as lanthanum and gallium have been investigated in preclinical as well as in clinical studies. The best known platinum(II) agents approved worldwide, cisplatin or carboplatin, are used in nearly 50% of all cancer therapies. This work focused on the development of new metal-based drugs that could act against human cancer cells. It was motivated in part by previous work with Cu(II) complexes, reporting new coordination compounds of SOD mimicking and cytotoxic activities. On the basis of this work we chose several commercially available heterocyclic ligands to synthesize new metal ion complexes in search of their interesting biological activity. New as well as previously reported Cu(II), Co(II), Pt(II) and Zn(II) complexes were synthesized using various ligands (1-6). Almost all chelating 2:1 ligand-metal complexes were obtained generally in water at room temperature in the reaction of metal(II) chloride with corresponding aromatic nitrogen ligands bearing an O-carboxylate group ligand. The synthesized chelating complexes were characterized by the use of spectroscopic methods, elemental analyses and HPLC chromatography and some by X-ray crystallography. Such coordination compounds are easily formed by transition metals with free orbitals d that can accept the donor electron pairs. The coordination is through the heterocyclic nitrogen and carboxylate ...

3A1653375485.jsonld | Das Unrecht der privaten Korruption im geschäftlichen Verkehr | The book examines the legal wrong of commercial bribery. Three central dogmatic and criminal-political issues of the reformed § 299 StGB are scrutinised, namely the criminal liability of the business owner de lege ferenda, the relevance of the principal's consent and the assessment of combined cases of third party advantages in favour of the principal. The unsatisfactory handling of these issues – especially by the prevailing opinion in case law and in literature – is seen as a symptom of a still-missing correct concept for the legal wrong of private corruption. After a critical analysis of traditional approaches, in particular of the prevailing “competition model”, a new approach is developed. This is done on the basis of the concept of corruption, which is characterised by the principal-agent approach, and of the normative foundations of a liberal criminal law. The legal wrong of private corruption is then seen as affecting the economic freedom or the freedom of competition of the entre-preneur (business owner). Finally, the consequences de lege lata and de lege ferenda of this reorientation for the interpretation and application of § 299 StGB are outlined. Die Arbeit untersucht das Unrecht der privaten Korruption im geschäftlichen Verkehr. Dabei werden drei zentrale, dogmatische und kriminalpolitische Fragen des reformierten Tatbestands des § 299 StGB unter die Lupe genommen, nämlich nach der Strafbarkeit des Geschäftsinhabers de lege ferenda, der Relevanz der Einwilligung des Geschäftsherrn und der Beurteilung der Konstellation der Drittvorteile zugunsten des Prinzipals. Deren unbefriedigende Behandlung – vor allem durch die herrschende Meinung in der Rechtsprechung und in der Literatur – werden als Symptome eines noch fehlenden, korrekten Konzepts zum Unrecht der Korruption im privaten Bereich angesehen.Nach einer kritischen Analyse der herkömmlichen Lösungsansätze, insbesondere des herrschenden Wettbewerbsmodells, wird der eigene Ansatz in Rückbesinnung auf den durch den Prinzipal-Agent-Ansatz geprägten Korruptionsbegriff und auf die normativen Grundlagen eines liberalen Strafrechts entwickelt. Das Unrecht der privaten Bestechung wird sodann in der Beeinträchtigung der wirtschaftlichen Freiheit bzw. der Wettbewerbsfreiheit des Unternehmers (Geschäftsinhabers) gesehen. Schließlich werden die Konsequenzen de lege lata und de lege ferenda dieser Neuorientierung für die Auslegung und Anwendung des § 299 StGB gezogen. | [

3A1040664725.jsonld | Minderheitenrechte und Interessenvermittlung : die Wirkung von Autonomie- und Konsultationsrechten in Lateinamerika aus vergleichender Perspektive | (How) Do autonomy and consultation rights foster indigenous self-determination? The book presents answers to this question, with its author proposing a comparative, methodologically innovative approach that takes particular account of the (often informal) patterns of interaction between indigenous groups and other stakeholders and examines them with network-analytical methods. By combining process tracing for within-case analyses of decision-making processes on infrastructure and extractive projects in Colombia, Panama and Chile with a cross-case analysis, the author demonstrates both causal mechanisms and causal patterns, and shows that indigenous rights are less decisive than expected. Instead, the book stresses the relevance of actor-specific and interaction-based conditions for safeguarding indigenous self-determination. In this respect, formalised internal modes of action and mobilisation resources of indigenous organisations are vital, as are prior interactions with public authorities. (Wie) Fördern Autonomie- und Konsultationsrechte indigene Selbstbestimmung? Um diese Frage zu beantworten, schlägt die Autorin einen vergleichenden, methodisch innovativen Ansatz vor, der die Ebene der (oft informellen) Interaktionsmuster zwischen unterschiedlichen Akteursgruppen besonders berücksichtigt und netzwerkanalytisch untersucht. Über die Kombination aus prozessanalytischen Fallstudien zu Entscheidungsverfahren über infrastrukturelle und extraktive Projekte in Kolumbien, Panama und Chile und deren vergleichender Analyse werden sowohl Wirkungszusammenhänge als auch kausale Muster aufgezeigt. Sonderrechte sind weniger ausschlaggebend als erwartet. Stattdessen wird die Bedeutung akteursspezifischer und interaktionsbasierter Voraussetzungen für die Wahrung indigener Selbstbestimmung betont: Formalisierte interne Handlungsmodi und Mobilisierungsressourcen indigener Organisationen sowie vorangehende Interaktionen mit staatlichen Institutionen sind entscheidend. | [

3A1010269682.jsonld | Art and Language: Explorations in (Post) Modern Thought and Visual Culture | Art and Language: Explorations in (Post) Modern Thought and Visual Culture sheds new light on the symbiotic relationship between art and language by exploring how these cultured sets consociate on philosophical and art-historical levels. Against the backdrop of (visual) semiotics the first section of the book considers the differences between art and language from various vantage points: meaning-making, asking if art is a language, Ernst Cassirer's symbolic forms, Jan Mukařovský's signs, and Gilles Deleuze's philosophy. The second section of the book deals with the works of (post) modern artists from diverse cultural backgrounds who unfasten traditional linguistic and artistic systems by destabilising the viewer and blurring the boundaries between art and language. The author argues that this is the most productive, cutting-edge aspect of the word-image relationship of that period. Language provides (post) modern art with its thrust and focus and offers a site for critical intervention. The artistic forays the author embarks on cover a wide range touching on Surrealism, Dada, Arabic Calligraphy, and Chinese Conceptualist Art. | [

3A1679321587.jsonld | Informationelle Selbstbestimmung und effektiver Rechtsschutz im Strafvollzug : Verwirklichungsbedingungen von Datenschutz und Informationsrechten im Vollzug von Freiheitsentziehungen | Data protection certainly isn’t the main concern of penitentiary inmates or administrations. But the issue of privacy in correctional institutions is especially well-suited to ask about the requirements for „good legislation“. This work makes suggestions how informational self-determination can be effective in prison thanks to appropriate statutory law. One of the main factors is the limited effectiveness of legal redress in prisons: How can the administration be “programmed” in such a way as to let the basic right to privacy come to fruition, if possible automatically?The correctional institution usually still confronts the inmates as a total institution. It can define and register their lives almost entirely. Therefore life behind bars is of particular interest in order to analyse the importance of data handling for individual freedom and social interactions. Based thereon the author develops practical guidance for legislation in the field of privacy that can easily be adopted for other fields of law. Fragen des Datenschutzes stehen bei Gefangenen und Vollzugsverwaltung meist nicht im Zentrum der Aufmerksamkeit. Doch stellen sich bei der informationellen Selbstbestimmung im Justizvollzug bespielhaft grundsätzliche Fragen „guter Gesetzgebung“. Diese Arbeit entwickelt Vorschläge, wie die informationellen Selbstbestimmung im Gefängnis durch zielgerichtete Rechtssetzung praktisch wirksam werden kann. Dabei misst sie der begrenzten Effektivität des Rechtsschutzes in der Haft besondere Bedeutung bei: Wie lässt sich das Handeln der Verwaltung in einer Weise anleiten, die die Bedeutung des Grundrechts möglichst von allein entfaltet?Der Vollzug tritt den Gefangenen weiterhin vielfach als totale Institution gegenüber. Er kann ihr Leben weitgehend bestimmen und erfassen. So eignet er sich besonders, um Fragen nach der Bedeutung von Datenverarbeitungen für die Persönlichkeit der Betroffenen und ihre sozialen Interaktionen zu stellen. Auf dieser Grundlage entwickelt die Arbeit konkrete Vorschläge für die Gesetzgebung, deren Grundgedanken sich leicht auf andere Lebensbereiche übertragen lassen. | [

3A1869979303.jsonld | Warum wir eine Erbschaftssteuer brauchen : eine philosophische Verteidigung | This volume conducts a defense of estate tax. Due to its progressive structure, tax is a tool well suited to counteracting growing economic inequality and, ultimately, to promoting various egalitarian ideals (political equality, equal opportunity). The defense rejects the most important objections against estate tax (property law, earnings, and family arguments) In der vorliegenden Arbeit wird eine normative Analyse und Verteidigung der Erbschaftssteuer unternommen. Zunächst wird eine egalitaristische Argumentation für die Steuer entfaltet. Aufgrund ihrer progressiven Struktur ist die Erbschaftssteuer ein geeignetes Instrument, um der wachsenden ökonomischen Ungleichheit entgegenzuwirken und letztlich verschiedene egalitäre Ideale (politische Gleichheit, Chancengleicheit etc.) zu befördern. Anschließend wird untersucht, wie aus normativer Perspektive zu beurteilen ist, dass der Erblasser bei Erhebung der Steuer nicht mehr lebt. Die restliche Arbeit besteht in einer Auseinandersetzung mit den wichtigsten Einwänden gegen die Erbschaftssteuer. So wird oft behauptet, diese verletze die natürlichen Eigentumsrechte des Erblassers bzw. des Erben und sie ignoriere zudem die Verdienstansprüche des Erblassers. Schließlich sei die Steuer aus diversen "familien-basierten" Erwägungen abzulehnen. Nicht nur werden diese Einwände erfolgreich zurückgewiesen; ferner wird gezeigt, dass einige der, diesen Argumenten zugrundeliegenden, Prinzipien selbst zur Verteidigung einer egalitären Erbschaftssteuer (also einer Erbschaftssteuer, die aus egalitären Prinzipien folgt) herangezogen werden können | [

3A87223827X.jsonld | Earthquake-induced landsliding : earthquakes as erosional agents across timescales | Earthquakes deform Earth's surface, building long-lasting topographic features and contributing to landscape and mountain formation.However, seismic waves produced by earthquakes may also destabilize hillslopes, leading to large amounts of soil and bedrock moving downslope. Moreover, static deformation and shaking are suspected to damage the surface bedrock and therefore alter its future properties, affecting hydrological and erosional dynamics. Thus, earthquakes participate both in mountain building and stimulate directly or indirectly their erosion. Moreover, the impact of earthquakes on hillslopes has important implications for the amount of sediment and organic matter delivered to rivers, and ultimately to oceans, during episodic catastrophic seismic crises, the magnitude of life and property losses associated with landsliding, the perturbation and recovery of landscape properties after shaking, and the long term topographic evolution of mountain belts.

3A1667882805.jsonld | Ich poste, also wähl' mich! : Parteien auf Facebook im Bundestagswahlkampf | This study investigates the communication strategies of German political parties on Facebook during the federal election campaign in 2013. Based on a model of digital communication in election campaigns designed by the author, it provides a detailed analysis of the topics, actors and instruments involved in election campaigning on social media. Using qualitative as well as quantitative social science research methods, the study relates the contents and objectives of the campaign to the reactions of potential voters. Analysing the debates that evolved from the posts by the political parties, the study provides important insights and knowledge, not only for further research but also for the future planning of social media campaigns. The research results not only reveal considerable differences in the campaign management between established actors and newcomer parties, but also confirm German parties' overall lack of dialogue and orientation towards demand. Instead of using the deliberative potential of network publicity, they merely seemed to reproduce the tried-and-tested marketing strategies of their offline campaign in the digital world. Mit der Analyse der Ziele und Inhalte der Facebook-Kampagne zur Bundestagswahl 2013 liegt nun eine Studie vor, die auf Basis eines eigenen Modells digitaler Wahlkampfkommunikation einen Überblick über die Themen, Akteure und Strategien postmoderner Kampagnen im Social Web vermittelt. Im Rahmen eines Mehrmethodendesigns wurden die Ergebnisse qualitativer Interviews und einer quantitativen Inhaltsanalyse im Anschluss mit den Reaktionszahlen der User verknüpft und um Einblicke in die qualitative Beteiligung in den Kommentarspalten ergänzt.Die Untersuchung legt dabei nicht nur erhebliche Unterschiede in der Kampagnenführung zwischen etablierten Akteuren und Newcomern offen, sie attestiert den deutschen Parteien insgesamt auch eine geringe Dialog- und Nachfrageorientierung. So nutzen die politischen Akteure das deliberative Potenzial der Netzwerköffentlichkeit nur rudimentär und übertragen stattdessen lediglich bewährte Marketingstrategien der Offline-Kampagne in die digitale Welt. | [

Therefore Thauera aromatica, Geobacter sulfurreducens, and Desulfococcus multivorans; bacteria belonging to different (predominant) anaerobic metabolisms, have been used. Despite smaller growth rates of the investigated anaerobic bacteria, toxicities of the chemicals were estimated using a growth inhibition test, which had already been established for aerobic bacteria. The compound toxicities were expressed as the 50% effective concentrations (EC50), which is the concentration of the chemical required to reduce the microbial growth rate by 50%. Direct relationships between toxicity and hydrophobicity (log P values) of organic compounds were ascertained for the different anaerobic bacteria ...

3A1748691821.jsonld | Der kartellrechtliche Marktbegriff und unentgeltliche Leistungen | How is the definition of the word market interpreted in German and European antitrust law? Julius Conrad Vocke develops a market definition and, based on examples from various sectors, studies which gratuitous performance relationships can be qualified as a market in accordance with this definition. In conclusion, he deals with the special requirements of the definition of gratuitous markets. Die Bestimmung des relevanten Marktes ist bei der Prüfung kartellrechtlicher Normen oft von entscheidender Bedeutung. In der bisherigen Praxis erfolgte sie regelmäßig primär anhand des Wettbewerbsparameters Preis. Bei unentgeltlichen Leistungen, die vor allem von digitalen Plattformen erbracht werden, stößt diese Vorgehensweise aber auf Schwierigkeiten: Unter welchen Voraussetzungen handelt es sich dabei um einen Markt? Wie ist ein solcher Markt abzugrenzen? Ausgehend von einer Auslegung des Marktbegriffs im deutschen und europäischen Kartellrecht entwickelt Julius Conrad Vocke eine Marktdefinition. Anschließend untersucht er anhand von Beispielen aus verschiedenen Branchen, welche unentgeltlichen Leistungsbeziehungen nach Maßgabe dieser Definition als Markt zu qualifizieren sind. Abschließend geht er auf die besonderen Anforderungen der Abgrenzung unentgeltlicher Märkte ein. Dabei beschäftigt er sich vor allem mit der Theorie der zwei- oder mehrseitigen Märkte und dem Wettbewerbsparameter Qualität. | [

3A87916218X.jsonld | Investigating cellular nanoscale with x-rays : from proteins to networks | The advances and technical improvements of X-ray imaging techniques, taking advantage of X-ray focussing optics and high intensity synchrotron sources, nowadays allow for the use of X-rays to probe the cellular nanoscale. Importantly, X-rays permit thick samples to be imaged without sectioning or slicing. In this work, two macromolecules, namely keratin intermediate filament (IF) proteins and DNA, both essential components of cells, were studied by X-ray techniques. Keratin IF proteins make up an integral part of the cytoskeleton of epithelial cells and form a dense intracellular network of bundles. This network is built from monomers in a hierarchical fashion. Thus, the keratin structure formation spans a large range of length scales from a few nanometres (monomers) to micrometres (networks). Here, keratin was studied at three different scales: i) filaments, ii) bundles and iii) networks. Solution small-angle X-ray scattering revealed distinct structural and organisational characteristics of these highly charged polyelectrolyte filaments, such as increasing radius with increasing salt concentration and spatial accumulation of ions depending on the salt concentration. The results are quantified by employing advanced modelling of keratin IFs by a core cylinder fl anked with Gaussian chains. Scanning micro- diffraction was used to study keratin at the bundle scale. Very different morphologies of keratin bundles were observed at different salt conditions. At the network scale, new imaging approaches and analyses were applied to the study of whole cells. Ptychography and scanning X-ray nano-diffraction imaging were performed on the same cells, allowing for high resolution in real and reciprocal space, thereby revealing the internal structure of these networks. By using a fitting routine based on simulations of IFs packed on a hexagonal lattice, the radius of each fi lament and distance between fi laments were retrieved. In mammalian cells, each nucleus contains 2 nm-thick DNA double helices with a total length of about 2 m. The DNA strands are packed in a highly hierarchical manner into individual chromosomes. DNA was studied in intact cells by visible light microscopy and scanning X-ray nano-diffraction, unveiling the compaction und decompaction of DNA during the cell cycle. Thus, we obtained information on the aggregation state of the nuclear DNA at a real space resolution on the order of few hundreds nm. To exploit to the reciprocal space information, individual diffraction patterns were analysed according to a generalised Porod’s law at a resolution down to 10 nm. We were able to distinguish nucleoli, heterochromatin and euchromatin in the nuclei and follow the compaction and decompaction during the cell division cycle. | [

3A1879441322.jsonld | Economic growth and environmental policy : a theoretical approach | The use of dynamic models to address the problem of environmental degradation is central to environmental policy because decisions taken now affect not only the current generation but have a profound impact on the future. In this innovative book, Frank Hettich uses dynamic modelling to study the interactions between economic growth, environmental policy and tax reform. He incorporates pollution and abatement technologies into different endogenous growth models that take into account consumer preferences and physical and human capital accumulation. He focuses on the effects of environmental policy in closed and open economies in the short, medium and long term. He sheds light on the following questions: * what kind of environmental policy can reverse tendencies towards increasing pollution? * will tighter environmental policy inevitably reduce economic growth? * does environmental taxation provide an efficient source of revenue for governments? * how will higher preferences for a clean environment affect optimal growth rates? * what are the effects of international cooperation on growth, welfare and pollution? * does sustainable environmental development necessarily preclude economic growth? This book will interest all students and scholars of environmental economics and particularly those interested in the relationship between economic growth and environmental quality | [

3A655424482.jsonld | Solidarische Ökonomie. Selbstverwaltung und Demokratie in Brasilien und Deutschland | Die vorliegende Doktorarbeit ist Ergebnis des Nachdenkens über Selbstverwaltung als ein Weg für Demokratisierung und solidarisches Wirtschaften. Begriff und Praxis der Selbstverwaltung wurden im Kontext der Bewegung für eine Solidarische Ökonomie untersucht. Deren Grundlage ist der Ansatz einer gesellschaftlich qualitativen Entwicklung, im Unterschied zum momentanen Entwicklungsmodell. Die Selbstverwaltung wurde insbesondere auf ihr Potenzial hin befragt, Männer und Frauen aus entfremdeten Verhältnissen zu befreien und sie wieder zu Akteuren ihrer eigenen Geschichte werden zu lassen. Zusammen mit der Achtung der individuellen Freiheit kann sich so ein demokratischer Prozess ergeben. Ein spezielles Augenmerk lag auf Entscheidungsprozessen und -instanzen innerhalb der Unternehmen, die sich dem solidarischen Wirtschaften verpflichtet fühlen. Hier wurde der Frage nachgegangen, wo konzentriert sich Macht in einer Person oder einer Gruppe, die einer Selbstverwaltung zuwider läuft. Für die vorliegende Untersuchung wurden zwei Studienobjekte ausgesucht, eines in Brasilien, ein anderes in Deutschland. Es sollten die Entscheidungsprozesse und -instanzen miteinander verglichen und ihre Wirkungen festgestellt werden, die diese auf die Entwicklung der Unternehmen ausgeübt haben. Die Tatsache, dass die beiden Studienobjekte verschiedenen sozialen und kulturellen Kontexten entstammen, erlaubt uns, den Rahmen der Analyse und Reflektion zu erweitern. Jedes Studienobjekt wies unterschiedliche Elemente auf. In der Gesamtschau ermöglicht dies einen breiteren Ansatz für die zukünftige Auseinandersetzung mit dem Thema Selbstverwaltung. / The thesis is the result of a study on self-management as a way to democratization and solidarity economy. The concept and practice of self-administration have been analyzed in the context of the movement for solidary economy, which is based on a social qualitative development in contrast to today's models of development. Selfmanagement has been analyzed in particular with regard to its potential to liberate men and women from the alienated conditions they are living in and making them agents of their own history. Together with the respect for individual freedom this can lead to a democratic process. Specific attention has been paid in this thesis to decision-making processes and authorities inside enterprises; there are committed to solidary economy. In this context the thesis has analyzed the concentration of power of individual people or groups counteract to solidary economy. The thesis focuses on two different case studies, one in Brazil and the other one Germany. The study's aim was to compare decision-making processes and authorities and their impact on the enterprises' development. The fact that both case studies are situated in different social and cultural contexts has allowed for expanding the study's analysis and discussion. Each case study has had specific characteristics. In summary, the thesis offers a new approach for future studies on self-management. | [

3A862573734.jsonld | Die exotisierte Stadt : Kulturpolitik und Musikvermittlung im postmigrantischen Prozess | This dissertation sketches the interaction between music mediation, cultural policies, and identity construction in today’s complex societies. Likewise, this study reveals how a global transcultural youth culture is emerging and developing under the influence of institutional structures. The debates on migration, which have continued to flare up in Germany since the early 1990s, and which are dominated by defensive attitudes regarding what is «one’s own» and other segregating tendencies, show the need for counteracting these tendencies by uncovering the underlying «imagined intercultural identities». The analysis of the «othering» in discourses of multi- or interculturalism within the «dispositive of interculture» and its educational and political objectives demonstrates how one tries to present the «exotic other» as homogenous. The ethnographic field study analyses how intercultural policies construct and label their target group through ascriptions of otherness, and, in doing so, uncovers which concepts of culture are applied by those responsible for intercultural projects and policies. Furthermore, it displays whether the attributed meanings and identities prove to be right at all. The results of this analysis demonstrate how a «transcultural» perspective can reveal an alternative point of view in cultural policies. This leads to the conclusion that cultural politics should and need to adapt to the realities of today’s post-migrant social processes. A transcultural post-migrant perspective in cultural politics centers on interactions, crossroads and (contradictory) commonalities, without emphasizing segregating tendencies. Likewise, these features are regarded as advantages within globalized settings and can lead to policies that underline the promotion of post-migrancy as a part of normal life. Die Analyse der Wechselwirkungen von Kulturpolitik, Musikvermittlung und jugendlichen Identitätskonstruktionen im Spannungsfeld der durch Migration und andere Einflüsse wie die hohe Mobilität von Informationen globalisierten Komplexität heutiger Gesellschaften legt die Entstehung von Jugendkulturen am Beispiel Hamburg offen. «Imaginäre Identitätsmythen» als Repräsentationssystem der Interkultur werden analysiert und ihre Zuschreibungsmechanismen, ihr exotisierendes Othering offengelegt. Durch die Feldstudie werden die Perspektiven der Kultur- und Bildungspolitik und der freien Kulturträger mit den Perspektiven der Jugendlichen in Korrelation gebracht. Gefragt wird, ob der Blickwinkel der Kulturpolitik einschränkend oder fördernd auf Jugendliche wirkt, und ob er mit den kulturellen Bedürfnissen der Jugendlichen übereinstimmt. Die Aktualität der Analyse liegt nicht zuletzt in der Brisanz segregierender Tendenzen im öffentlichen Meinungsklima in Bezug auf «Jugendliche mit Migrationshintergrund». Die Ergebnisse der Forschung liefern Empfehlungen, deren Umsetzung eine wünschenswerte, wenn nicht gar notwendige Adaption der Kulturpolitik an die Realitäten des heutigen postmigrantischen Gesellschaftsprozesses darstellt. Anstelle der Verfestigung von segregierenden Zuschreibungen Vorschub zu leisten, bietet eine solche transkulturelle Perspektive die Möglichkeit, Verflechtungen, Interaktionen und (auch widersprüchliche) Gemeinsamkeiten im globalisierten Kontext als Vorteil zu begreifen und sich der Ermöglichung von postmigrantischer Normalität zu verschreiben. | [

If the transfer is not properly executed, the question of restitution of the transfer amount and compensation for any consequential damage arises. In determining the law applicable to these issues, conflict-of-law rules traditionally follow a segment-related approach. Jaroslav Cejka deals specifically with the question of whether this approach should be maintained in international credit transfer law or whether the factual context of the individual giro relationships requires the application of one single legal system to the entire credit transfer operation. Eine grenzüberschreitende Überweisung besteht regelmäßig aus einer Kette von Giroverhältnissen, die vom Überweisenden über eine oder mehrere Banken bis zum Überweisungsempfänger reicht. Bei einer fehlerhaften Ausführung der Überweisung stellt sich zum einen die Frage nach der Rückgewähr des Überweisungsbetrags. Zum anderen ist zu klären, ob und auf welche Weise dem Überweisenden etwaige Folgeschäden ersetzt werden müssen. Traditionellerweise wird das anwendbare Recht für jeden bilateralen Girovertrag in der Überweisungskette gesondert ermittelt, wodurch Normenwidersprüche entstehen können. Jaroslav Cejka setzt sich mit der Fragestellung auseinander, ob dieser segmentbezogene Ansatz im internationalen Überweisungsrecht interessengerecht ist, oder ob der sachliche Zusammenhang der einzelnen rechtlichen Glieder einer Überweisung es erfordert, eine einzige Rechtsordnung auf den gesamten Überweisungsvorgang anzuwenden. | [

Sauer's study examines the instruments of gendered policy analysis and the conditions under which they are being used by the Canadian federal government and the European Commission. Interviews with experts from public administration and instrument designers as well as document analyses reveal benefits and challenges and show that the success of equality governance depends upon whether knowledge about gendered policy and appropriate administrative practices are embedded, embodied and entrenched in public administration. | [

3A1013753658.jsonld | Metabolomic analysis of the allelopathic interactions between marine planktonic microalgae | Diatoms are of essential importance for marine and terrestrial ecosystems, especially in bloom events. It is thus of high interest to unravel underlying mechanisms of allelopathic phytoplankton dynamics, particularly in bloom situations. So far, research focused on negative allelopathic effects and, if at all, allelochemicals involved in negative allelopathic effects were described. By choosing an untargeted, comparative GC/TOF-MS - based metabolomic approach with continuous monitoring of diatom cultures, this thesis aims at further characterizing diatom interactions in the context of allelopathy. The focus is set on the interaction of Skeletonema sp. with the co-occurring species T. weissflogii. Compared to previous studies, the identification of significant interaction-induced metabolomic responses was advanced by combining elaborate co-cultivation set-ups with GC/TOF-MS metabolomic profiling techniques. In this context, available MS libraries facilitated the identification of significant metabolites. ... | [

Apart from providing the world’s first measurement of these interactions in a mostly unexplored energy region, the data presented advances the neutrino community’s preparedness to search for an asymmetry between matter and anti-matter that may very well provide the physical mechanism for the existence of our universe. The details of these measurements are preceded by brief summaries of the history of the neutrino, the phenomenon of neutrino oscillations, and a description of their interactions. Also provided are details of the experimental setup for the measurements and the muon antineutrino cross-section measurement which motivates the need for dedicated in situ background constraints. The world’s first measurement of the neutrino component of an antineutrino beam using a non-magnetized detector, as well as other crucial background constraints, are also presented. By exploiting correlated systematic uncertainties, combined measurements of the muon neutrino and antineutrino cross sections described in the book maximize the precision of the extracted information from both results | [

3A1010263080.jsonld | Signaling cascades of the Aspergillus fumigatus virulence factor Gliotoxin in mediating apoptosis and invasive aspergillosis | Abstract: Gliotoxin (GT) is the major virulence factor of the fungus Aspergillus fumigatus (A.f.) and necessary to promote invasive aspergillosis (IA) in immunocompromised patients. Disease progression requires GT-mediated loss of epithelial barrier function to allow the invasiveness of A.fumigatus. GT-induced apoptosis of epithelial cells could contribute to such function. <br>Here we further characterize the apoptotic signaling induced by GT. We show that GT triggers RhoA activation, which induces a kinase cascade via the Rho-associated kinase (ROCK) and the MAPK kinases MKK4/7. MKK4 and MKK7 activation precedes phosphorylation of c-Jun N-terminal kinases (JNK) and subsequent phosphorylation of Bim. Phosphorylated Bim is released from anti-apoptotic Bcl-2 and interacts with Bak to execute GT-induced apoptosis. In this context, ROCK functions as a MAPKK kinase to relay apoptotic signaling in addition to its known function on the cytoskeleton. We found that cells were resistant to GT-induced apoptosis if they were either (i) treated with JNK or ROCK inhibitors or (ii) genetically deleted or knocked-down for ROCK-1 or MKK4/7. <br>GT triggers cell death by a cell detachment-induced mode of apoptosis, termed anoikis. We report that GT can directly bind to cysteines in the ligand binding domain of integrin αVβ3. Furthermore, GT rapidly inactivates integrins to trigger anoikis. Integrin inactivation resulted in the inhibition of focal adhesion kinase (FAK) and p190RhoGAP to activate the RhoA-dependent kinase cascade. We establish GT as a novel, physiological trigger to study anoikis and integrin signaling.<br>Both loss of epithelial cells by apoptosis and/or cell detachment could underlie the reduced barrier integrity. Here we show that ROCK inhibitors not only block GT induced cell death but also maintain the physiological morphology by preventing detachment of bronchial epithelial cells. Pharmacological inhibition of ROCK might therefore be a promising strategy to prevent the invasive potential of A.fumigatus Abstract: Gliotoxin (GT) ist der zentrale Virulenz Faktor des Schimmelpilzes Aspergillus fumigatus (A.f.) und verantwortlich für die Manifestation von invasiver Aspergillose (IA) in immunsupprimierten Patienten. Die Invasivität von A.f. beruht hierbei auf dem GT-induzierten Verlust der Barrierefunktion des Lungenepithels. GT-induzierte Apoptose von Epithelzellen könnte in diesem Zusammenhang eine wichtige Rolle spielen.<br>Ziel dieser Arbeit war es die GT-abhängigen, pro-apoptotischen Signal Kaskaden zu charakterisieren. GT aktiviert die GTPase RhoA, welche über die nachgeschaltete Kinase ROCK, die folgende Kinase-Kaskade stimuliert: ROCK phosphoryliert die MAPK Kinasen MKK4 und MKK7, welche wiederum JNK phosphorylieren und somit aktivieren. Diese Kaskade endet mit der JNK-abhängigen Phosphorylierung von Bim und der damit verbundenen Freisetzung von Bcl-2. Bim ist dann in der Lage mit dem Effektor Protein Bak zu interagieren, um die GT-induzierte Perforation von Mitochondrien und somit Zelltod umzusetzen. <br>In diesem Zusammenhang fungiert ROCK als eine pro-apoptotische MAPKK Kinase, zusätzlich zu seiner bekannten Funktion in der Regulation von Zellmorphologie. Dementsprechend wurde gefunden, dass Zellen resistent gegen GT induzierte Apoptose waren, wenn sie (i) mit JNK oder ROCK Inhibitoren behandelt wurden, oder (ii) ROCK oder MKK4/7 genetisch reduziert beziehungsweise ausgeschaltet waren.<br>Interessanterweise bewirkt GT das Ablösen von Zellen. Dieser Vorgang kann den programmierten Zelltod einleiten und wird dann als Anoikis bezeichnet. Wir konnten zeigen, dass GT direkt relevante cysteine in der Ligandenbindungsdomäne von Integrin αVβ3 modifiziert. Zusätzlich inaktiviert GT Integrine, um Anoikis zu vermitteln. Integrin Inaktivierung induziert die Inhibition der Focal Adhesion Kinase (FAK) und des nachgeschalteten Faktors p190RhoGAP, um die RhoA abhängige Signal Kaskade zu stimulieren. Somit wirkt GT als ein neuartiger und physiologischer Stimulus, um Anoikis zu induzieren und Integrin-abhängige Signaltransduktion zu studieren.<br><br>Wir zeigen, dass ROCK Inhibitoren sowohl den GT-induzierten Zelltod als auch das Ablösen von Zellen verhindern konnten und daher in der Lage waren, die Epithelzell-Morphologie zu erhalten. Da diese beiden Mechanismen ursächlich für die GT vermittelte Invasivität von A.f. sein könnten, könnte die pharmakologische Inhibition von ROCK eine interessante Strategie zur Bekämpfung von IA ... | [

3A1760914371.jsonld | An exploration of context updating mechanisms from a cross-linguistic perspective | Presupposition is what people make use of on a daily basis. It is therefore crucial to comprehend how a presupposition gets projected in a sentence. This thesis focuses on three major presupposition projection mechanisms, namely left-right asymmetric, symmetric and hierarchical approaches. For the reason that the majority of previous research is undertaken on the basis of English data, this thesis evaluates these mechanisms employing Japanese and Chinese empirical evidence. The analyses and experimental data in this thesis confirm that, firstly, the left-right asymmetric account which is substantiated by English empirical evidence is not tenable in Japanese and Chinese. Secondly, the symmetric approach appears to be promising in both English and Japanese, though it has not been sufficiently investigated. Thirdly, the hierarchical framework can account for English, Japanese and Chinese empirical evidence preliminarily. Much more attention should be paid to the hierarchical approach to presupposition projection in further studies. Further investigation into this topic can deepen the comprehension of human language and language processing. | [

3A870290177.jsonld | Characterization and modeling of the influence of the ageing treatment on the precipitation process and the mechanical behavior of the AlSi10Mg(Cu) aluminum alloy | A major objective of the current engine development projects is the downsizing of engines, which leads to more demanding specifications for the design of aluminum cylinder head castings such as higher operating temperatures or increased combustion pressures. As a result, these internal combustion engine components are subjected to more severe thermal loads related to the start-operate-stop cycles of the engine which produces low-cycle fatigue loading conditions in the material. Therefore, the initial ageing condition of the alloy as well as the subsequent thermal loading during the component service have a great impact on the cylinder head mechanical response and lifetime predictions. For this reason, mechanical models which can consider the ageing condition in the alloy are highly appreciated in this field. A comprehensive analysis of the effect of the artificial ageing on the precipitation process of the age-hardenable AlSi10Mg(Cu) aluminum alloy from T6 to T7 condition and its influence on the mechanical behavior of the alloy at elevated temperatures is presented in this work, considering the influence of temperature and time ageing conditions of interest. The influence of the artificial ageing on the material microstructure is carried out considering the most important microstructure compounds usually present in Al-Si-Mg alloy systems. A complete quantitative characterization of the Mg2Si precipitation distributions covering a broad range of ageing conditions is obtained using the small angle neutron scattering (SANS) technique, complemented with high-resolution transmission electron microscopy (HTEM). This information is used to fit Robson's precipitation model for the prediction of the precipitation distribution as function of time and temperature. Based on the measured precipitation behavior, a sigmoidal interface energy function is added to Robson's model. As a result a unique set of modeling parameters is obtained for the whole precipitation process. Therefore, Robson's model is shown to be a powerful tool for predicting the evolution of these nanometer-scale particles in industrial and complex ageing processes. The influence of the ageing condition on the mechanical response of the alloy to different loading conditions is also examined. Hardness measurements and tensile tests are performed at room temperature. At higher temperatures, creep and low-cycle fatigue tests are carried out to analyze the relationship existing between the precipitation distributions and the mechanical response of the alloy. The predominant strengthening mechanism at this high temperature regime is determined from these results. The information obtained from this analysis is of great importance for the mechanical modeling using Steck's viscoplastic material model considering both isotropic and kinematic hardening. This constitutive mechanical model is further developed in this work to consider combined cyclic and relaxation loading conditions by using a unique set of modeling parameters independent of each other and of temperature. According to the results presented, Steck's model is especially useful at elevated temperatures, of interest in this work. Finally and based on the physic principles of both precipitation and material models, Steck's material model is extended to consider the alloy ageing condition in the kinematic and isotropic hardening components. The results obtained for an intermediate overaged condition of the alloy using the extended Steck's constitutive model make this model combined with Robson's precipitation model a good approach to predict the mechanical behavior of the AlSi10Mg(Cu) aluminum cast alloy at high temperatures considering the potential effect of further thermal loading, which is of great interest for its industrial application in future cylinder head design projects. | [

3A873726804.jsonld | Präparation, Charakterisierung und Anwendung von photovernetzbaren Mikrogelen | Zusammenfassung: The goal of this thesis was the development of photo-crosslinkable model colloids and their application to permanently link transient crystallites and clusters in dispersions of polystyrene microgels. The photo-crosslinking was conducted by a [2+2]-cycloaddition of covalently attached coumarin derivative on the particles’ surfaces. For further analysis of the persistent clusters a technique to produce small, fluorescent microgels was developed.Following other theses of the work-group polystyrene particles were synthesized by emulsion polymerization. These particles were crosslinked to microgels by add-ing 1mol-% of diisopropylene benzene (crosslinking density 1:50). The coumarin derivative and the fluorescent dye were functionalized as methacrylic acid esters to ensure the covalent attachment of the chromophores to the polymer. By employ-ing the seeded growth-method the photocrosslinkable coumarin groups were ex-clusively located on the particles surface. The influence of the solvent on the pho-toreaction and different sources of radiation were investigated in a comparing study. It was found that the photocrosslinking works most efficiently in 1-methyl naphthalene and with a UV-laser (λ = 355 nm). These experimental parameters allowed for photocrosslinking, fluorescent microscopy and light scattering on the same samples | [

3A820501735.jsonld | Opportunities of Cross-fertilization between law and experimental economics | In Chapter II we investigate consumer behavior when facing target rebates, a rebate practice challenged by antitrust law. In three experiments, we confirm the hypothesis derived from Cumulative Prospect Theory (CPT), that target rebates are likely to create psychological switching costs that can make target rebates a tool dominant firms can use to inefficiently foreclose markets. In an experiment reported in Chapter III I confirm that guilt aversion, i.e., a preference to fulfill other people’s expectations, plays out stronger if agents are socially close. The hypothesis was triggered by legal intuition but can also be derived from psychological theory and seems to structure the previous literature on guilt aversion well. The cautious ingroup-outgroup manipulation that generates the result makes allows the presumption that the effect is way stronger in the field where relationships rest on friendship, family ties or co-workership. In Chapter IV we study how intra-team conflict and knowledge thereof influence inter-team competition. We model intra-team conflict (hereafter: “conflict”) by connecting a team’s pricing decision to the intra-team profit division. Inter-team competition is modeled as a Bertrand duopoly with homogeneous goods. We vary market composition (two conflict-teams, one conflict-team and one no-conflict-team, two no-conflict teams) and the availability of information regarding conflict of the other team (hereafter: “information”). We find that (1) prices are higher in homogenous markets of conflict-teams than in homogeneous markets of no-conflict teams. (2) With information, prices in heterogeneous markets are as low as in homogenous markets of no-conflict teams. (3) Without information on the other team’s conflict, prices in heterogeneous markets are as high as in homogenous markets of conflict-teams. (4) Information on the other team’s conflict leads to higher prices in homogeneous markets but to lower prices in heterogeneous markets. | [

Therefore, the physiological differences along the intestinal tract regarding pH, transit and microbial colonization can be used. However, various factors such as food intake or pathophysiological changes can lead to a fail of pH - , time - or enzyme -triggered dosage forms. They could release their active pharmaceutical ingredient (API) either too early, too late or not at all. With the development of new dosage forms releasing their active ingredient based on a defined pressure, these problems could possibly be avoided. Another point which can negatively affect the bioavailability in the human body, with particular respect to poorly soluble drugs, is the exact time and duration of the disintegration of a dosage form and a lack of the required volume of liquid in the gastrointestinal tract. Especially drugs with a narrow absorption window in the upper small intestine depend on a rapid dissolution process of the active ingredient of a dosage form to provide an optimal absorption. For this reason, the aim of the present work was the development of new pressure-sensitive dosage forms, releasing their content immediately and completely at a defined pressure of 300 mbar, which is predominant at the pylorus.

3A1700420836.jsonld | High-harmonic generation with Laguerre-Gaussian beams | High-harmonic generation is a versatile process, for one thing, useful to explore the structure of atoms or molecules during the generation itself and apart from that a source of bright, short, coherent extreme ultraviolet radiation. Thereby the harmonic radiation can be controlled by the shape of the driving laser with respect to its polarization or frequencies. Recent advances show that Laguerre-Gaussian beams, which carry in addition to their spin also orbital angular momentum, can be utilized for high-harmonic generation. In this thesis, we analyze high-harmonic generation with Laguerre-Gaussian beams in the framework of the strong-field approximation and show that this requires both the interaction of a single atom with the driving laser and the macroscopic superposition of all single atom contributions. We first investigate high-harmonic generation with linearly polarized Laguerre-Gaussian beams. There, we show how the orbital angular momentum of the driving laser is transferred to the generated harmonics. Here, we developed vivid photon diagrams to explain the conservation of orbital angular momentum. We then consider phase matching of the generated radiation in order to increase the conversion efficiency. In particular, we analyze the coherence length at different positions in the generating beam. Furthermore, we investigate high-harmonic generation with a pair of counter-rotating circularly polarized Laguerre-Gaussian beams. Here, we derive selection rules that take account of the conservation of energy, spin and orbital angular momentum. In addition, we show that the orbital angular momentum of the generated harmonics can be precisely controlled by the orbital angular momentum of the driving beam. | [

3A56555915X.jsonld | Beyond the shadows of utility : evolutionary consumer theory and the rise of modern tourism | A generic feature of advanced economic development is the rapid emergence of what Konrad Lorenz dubbed the ‘Pleasure Economy’ the rising percentage of household income spent on leisure consumption (Lorenz 1970). To explain such long run shifts in consumption, it is necessary to do away with the shadow that modern utility theory casts on the nature of consumer tastes and to investigate how these have indeed evolved in the face of a continuously expanding and increasingly heterogeneous set of consumption opportunities. Starting with the basic conjecture that the expansion of consumption is shaped by a set of biologically evolved behavioral predispositions which are inherent in the consumer’s genetic endowment (Witt 2001), we examine the historical emergence of certain types of tourism to show how the interplay between these ‘wants’ and the act of recreational travel may account for the explosive growth of modern tourism activity. | [

3A1664910514.jsonld | Basic cognitive processes of intelligence | Abstract: This thesis discusses important issues concerning the basic cognitive processes of intelligence. In recent empirical research on individual differences on cognitive abilities, several cognitive processes have been related to intelligence. Specifically, the capacity of working memory, processing speed or executive function (i.e. attention regulation mechanisms) have been identified as important cognitive correlates of intelligence. Within this thesis, I discuss how cognitive models as measurement tools for theoretically sound indicators of these cognitive processes may enrich research on the basic cognitive processes of intelligence. In addition, I provide an example how to establish that parameters from cognitive models poses trait like properties and thus qualify as adequate predictors of intelligence. Furthermore, I present a new methodological approach for analyzing the worst performance rule, an important phenomenon in intelligence research that has been linked to processing speed and attention regulation. And finally, I present results from an empirical study that aimed to bridge the gap between working memory capacity, processing speed, and executive functions as important predictors of intelligence. All in all, this work summarizes the core aspects of process oriented research on intelligence and outlines how future research may provide more comprehensive results identifying specific process parameters that underlie individual differences in our cognitive abilities In der vorliegenden Doktorarbeit werden wichtige Fragen zu den grundlegenden kognitiven Prozessen der Intelligenz behandelt. In der jüngsten empirischen Forschung zu individuellen Unterschieden in der kognitiven Leistungsfähigkeit wurden verschiedene kognitive Prozesse mit Intelligenz in Verbindung gebracht. Insbesondere wurden die Kapazität des Arbeitsgedächtnisses, der Verarbeitungsgeschwindigkeit oder von Exekutiven Funktionen (d.h. Aufmerksamkeitsregulationsmechanismen) als wichtige kognitive Korrelate von Intelligenz identifiziert. In dieser Arbeit diskutiere ich, wie kognitive Modelle als Messinstrumente für theoretisch fundierte Indikatoren dieser kognitiven Prozesse die Erforschung der grundlegenden kognitiven Prozesse der Intelligenz bereichern können. Außerdem gebe ich ein Beispiel, wie man feststellen kann, dass Parameter kognitiver Modellen Trait-Eigenschaften aufweisen und somit als adäquate Prädiktoren für Intelligenz verwendet werden können. Darüber hinaus präsentiere ich einen neuen methodischen Ansatz zur Analyse der Worst Performance Rule, einem wichtigen Phänomen in der Intelligenzforschung, das mit der Verarbeitungsgeschwindigkeit und der Aufmerksamkeitsregulierung verknüpft ist. Abschließend stelle ich Ergebnisse einer empirischen Studie vor, die darauf abzielte, die Lücke zwischen Arbeitsgedächtniskapazität, Verarbeitungsgeschwindigkeit und Exekutiven Funktionen als wichtige Prädiktoren für Intelligenz zu schließen. Alles in allem fasst diese Doktorarbeit die Kernaspekte der prozessorientierten Forschung im Bereich der Intelligenz zusammen und skizziert, wie zukünftige Forschung umfassendere Ergebnisse liefern kann und spezifische Prozessparameter identifiziert, die individuellen Unterschieden in unseren kognitiven Fähigkeiten zugrunde liegen. | [

3A1002759765.jsonld | Studies on issues in political economy since the Global Financial Crisis | The dissertation includes four studies broadly connected to the causes and consequences of the Global Financial Crisis of 2007-8 from a political economy perspective. Following the intro-duction, Chapter 2 analyzes the political roots of massive foreign reserves accumulation, which has contributed to the American credit boom before the financial crisis. The study shows that elections tend to explain why democracies have acquired less foreign reserves than authoritarian regimes. Basel III was a regulatory consequence of the Global Financial Crisis, which is scheduled to impose liquidity requirements as a prudential measure for commercial banks. Chapter 3 examines whether these liquidity requirements could have an unintended negative effect on monetary stability. Based on a new dataset of reserve and liquidity requirements, the results show that inflation is more robust to changes in the velocity of money if reserve and liquidity requirements are low. Increases in the velocity of money are associated with higher inflation rates if reserve and liquidity requirements are high. The ability of partisan politics to shape economic policies according to ideological goals has been regularly questioned in an era of globalization and austerity. Chapter 4 suggests that government ideology still has a pronounced impact on economic policy-making based on a sample of OECD and new EU member states. Chapter 5 analyzes why major business leaders in France and Germany have publicly supported the euro in the weeks before a bailout program got enacted by the European Council in July 2011. The study shows that direct corporate interest did not appear to matter. Instead, business leaders appeared to be more likely to join the campaign if they were well-connected in business and political networks. The findings suggest that managers disregarded their short-term economic interest to improve their long-term ties with political decision-makers. Die Dissertation behandelt in vier Kapiteln Themen zu den Ursprüngen und Auswirkungen der globalen Finanzkrise 2007-8. Nach der Einleitung untersucht Kapitel 2, warum autoritäre Regime im Vergleich zu Demokratien vor und nach der Finanzkrise eher in der Lage waren, größere Bestände an Währungsreserven anzuhäufen. Die empirische Analyse zeigt, daß Wahlzyklen ausschließich in Demokratien zu einer signifikanten Reduzierung von Währungsreserven führten. Kapitel 3 zeigt, daß die Deregulierung der Banken-Mindestreserve einen negativen Einfluß auf die Volatilität der M2-Geldmenge und der Inflationsrate hat. Dies könnte eine weitreichende Bedeutung haben, da die Mindestreserve in Form von Liquiditätsanforderungen ein Hauptbestandteil der Basel III Regulierung ist, die bis 2019 in Kraft treten soll. In Kapitel 4 gehe ich der Frage nach, ob die Regierungsideologie in Zeiten von Globalisierung und Austeritätsprogrammen noch eine Rolle in der Wirtschaftspolitik spielt. Basierend auf einen Index, der die wirtschaftliche Freiheit für diverse Politikfelder mißt, zeigt das Kapitel, daß rechte bzw. klassisch liberale Regierungen dazu tendieren, die wirtschaftliche Freiheit signifikant zu erhöhen, während sie unter linken bzw. sozialdemokratischen Regierungen stagniert. Das fünfte Kapitel untersucht, warum deutsche und französische Top-Manager - auf dem Höhepunkt der Eurokrise - den Euro öffentlich in einer Anzeigenkampagne unterstützten. Während die Firmeninteressen anscheinend keinen direkten Einfluß haben, verfügten die Unterstützer der Euro-Kampagne über mehr Netzwerkkontakte zu Wirtschaftsverbänden und Politik. Dieses Ergebnis suggeriert, daß führende Manager den Euro öffentlich unterstützten, um ihr politisches Kapital zu EU- und nationalen Entscheidungsträgern zu wahren oder zu verbessern. | [

In this context, the role of the US Congress in directing the outcome of national security policies is often overlooked. This book illustrates how Congress played a key role in the War on Terror during Barack Obama’s presidency. Instead of arguing that Congress was a compliant bystander and incapable of making successful counterterrorism policy, the legislative branch did more than hand the president a blank check. In using an innovative data set on congressional debates and policymaking, the book shows that the interaction between congressional entrepreneurs and senior committee/party leaders determined the outcome of controversial policies, including drone warfare, Guantanamo and the NSA’s mass surveillance activities. Welche Rolle spielte der US-Kongress im Krieg gegen den internationalen Terrorismus während der Präsidentschaft Obamas? Die außenpolitiktheoretische Studie weist die vorherrschende These einer willfährigen amerikanischen Legislative in der nationalen Sicherheitspolitik zurück und betont den Einfluss des Kongresses bei der Diskussion um die Schließung Guantanamos, den Drohnenkrieg oder der Reform der NSA-Überwachungsaktivitäten. Während die inhaltsanalytische und prozessuale Falldiskussion einerseits die Bedeutung von Kongress-Entrepreneuren zur Verteidigung der verfassungsrechtlichen Autorität des Kongresses gegenüber dem Präsidenten belegt, zeigt sie andererseits den institutionellen Schulterschluss der Fraktionsspitzen und Vorsitzenden der Fachausschüsse beider Kammern mit der Exekutive. | [

3A588765198.jsonld | Formation and characterization of stochastic subwavelength structures on polymer surfaces | When PMMA is exposed to plasma, a stochastic surface morphology forms under certain conditions. The surface shows a notable transmittance increase in the visible spectral region. Moreover, the technology is an inexpensive alternative to the deposition of interference coatings to increase the light transmission of polymeric optical elements. The principle of antireflective subwavelength structures is also known from the "moth's eye". This work is driven by the need to fabricate such broadband antireflective morphologies on arbitrary shaped surfaces of different kinds of polymers. Beside PMMA, three transparent thermoplasts were chosen to analyze the physical processes in order to understand the structure formation. The plasma-polymer interaction was supported by Monte Carlo method to investigate the energy transfer of the ions on the substrate. The optical effect of the structured surfaces has been optimized by the use of spectrophotometry. The structure formation has been analyzed by AFM and SEM. The revealed effective pin shape was correlated with the results from spectral reverse engineering. The structure formation has been established on the surface of the polymers and shows a self-organized nature, since the topography was not prescribed from outside before or during the process. The differences in size, shape, and antireflective effect are specific for the particular polymer. The structure formation results from a combination of physical sputter-erosion and chemical etching. Aspect ratios of the pin structure above 1 can only be explained by anisotropic etching due to impact of high energetic plasma-ions. The structure has been modeled as effective medium, which allows for the subsequent description by means of graded-index layers. The occurrence of scatter losses can be kept low and might be negligible for many applications. Particular PET surfaces show an industrially appropriate transmittance increase in the visible spectral region after plasma treatment. | [

3A834855739.jsonld | Electronic and topological properties of low-dimensional α-Sn and HgTe structures | The electronic and topological properties of alpha-Sn (a-Sn) and HgTe and their low-dimensional systems are studied by means of ab-initio calculations. The used approximate quasiparticle theory including spin-orbit coupling (SOC) gives the correct band ordering, band gap and SOC-splitting for bulk a-Sn, HgTe and CdTe. Calculating the topological invariants, a-Sn and HgTe are shown to be topological insulators, whereas CdTe is identified as trivial insulator. These findings suggest the occurrence of the quantum-spin Hall (QSH) phase in the respective low-dimensional systems, which is characterized by topologically protected spin-polarized edge-of surface states. For a-Sn nanocrystals, a topological transition indicated by an inversion of the electronic level-ordering for a certain critical diameter is found. In addition, the diameter-dependent optical absorption-and emission properties are investigated in detail. In a-Sn(001) surfaces, the occurrence of spin-polarized topological surface states, although inside the inverted bulk band gap is demonstrated in agreement to recent angle-resolved photoemission studies. The investigation of HgTe/CdTe and a-Sn/CdTe quantum-well (QW) structures shows a topological transition from the topological trivial insulating state into a non-trivial QSH insulator with increasing QW thickness. The spatial localization of the wave functions near the interfaces and the spin polarization are demonstrated for the edge states for QWs with thicknesses near the critical one. They do not depend on the QW orientation and are therefore topologically protected. We show that the inclusion of inversion symmetry, the non-axial rotation symmetry of the QWs, and the real QW barriers lead to some agreement but also significant deviations from the predictions within toy models. Real structure effects becom most improtant in a-Sn/CdTe(001) Qws, where the QSH phase is suppressed by an intrinsic electrostatic saw-tooth potential. | [

3A1852703261.jsonld | Salience in decision-making : a neuroeconomic analysis | Attention and the closely related concept of salience play an important role in the complex process of human decision-making. In 2012, Bordalo et al. (2012a) proposed a theory on human decision-making that is based on salience. They suggest that salience differences within a decision problem may explain many decision biases. Concerning decisions under risk, Bordalo and colleagues developed a formula to calculate salience differences that are shaped by bottom-up processes. These salience differences have been experimentally investigated. Reaction times in a dot-probe task served as indicator of attentional biases. Data revealed a significant salience effect after a lottery exposure duration of 150 ms. This supports the salience concept proposed by Bordalo et al. (2012a) and suggests an early attentional orienting towards salient payoffs. In order to further differentiate attentional processes involved in the salience effect EEG has been recorded. Different ERP-components may indicate attentional biases at different stages of attentional processing and give a hint at more detailed reasons behind the salience effect. All investigated components, namely, P1, N1, P3a and P3b, showed no significant salience differences. Part III presents a further experiment that was devoted to nudges. These interventions often work by altering the salience within a decision problem or by directing the attention to the decision task itself. Since these interventions influence decisions at least partly on an unconscious level, nudges are subject to criticism. The experiment aimed at investigating the effect of transparent information accompanying the nudges on their efficacy. In line with previous research adding information on the nudge itself, on its purpose and the combination of both had no significant effect on the efficacy of the nudge, even though this additional information again alters salience ratios within the decision problem. | [

Thus, this method yields films with applications in diverse areas including biology and medicine. Sequential adsorption of different oppositely charged macromolecules can be used to prepare tailored films with controlled molecular organization. In biomedical research, electrically conductive coatings are of interest. In manuscript 1, we investigated films sequentially assembled from the polycation poly (diallyldimethyl-ammonium) (PDADMA) and modified carbon nanotubes (CNTs), with CNTs serving as the electrically conductive material. We assume that charge transport occurs through CNT contacts. We showed that with more than four CNT/PDADMA bilayers, the electrical conductivity is constant and independent of the number of CNT/PDADMA bilayers. A conductivity up to 4∙10^3 S/m was found. It is possible to control the conductivity with the CNT concentration of the CNT deposition suspension. A higher CNT concentration resulted in thicker CNT/PDADMA bilayers, but in a lower conductivity per bilayer. We suspect that an increased CNT concentration leads to a rapid CNT adsorption without the possibility to rearrange themselves. If PDADMA then adsorbs on the disordered CNTs in the next deposition step, the average thickness of the polymer layer is thicker than on the more ordered CNT layer from the dilute ... | [

The dissertation focuses on the elements within these works which anticipate the later Revisionist Western genre. The study explores the Classic American Western’s role in expressing contemporary conditions of non-normative issues and socio-cultural groups in canonical fiction. This focus ranges from defining the Classic and Revisionist Western genres whose narratives are informed by the normative elements of white, heterosexual working-class masculinity, to inclusive research which expands canonical readings to African American and Native American Western fiction. This work explores how the intersectional convergence of class, race, and gender was accomplished by these authors through appropriating the thematic and mytho-nationalist ethos of the Western in order to challenge subaltern positions | [

3A1655152858.jsonld | Search for supersymmetric particles in final states with leptons, jets and missing transverse energy with the ATLAS detector. | Abstract: Supersymmetry (SUSY) is one of the most studied models to extend the Standard Model (SM) of Particle Physics beyond the electroweak scale. <br>In many supersymmetric models, the lightest supersymmetric particle is stable and can be a suitable candidate for dark matter.\\<br>This dissertation summarises a search for supersymmetric phenomena produced via the strong or the electroweak interaction leading to final states with two leptons (electrons or muons) of the same electric charge, or three leptons, jets and missing transverse momentum. While the same-sign or three leptons signature is present in many SUSY scenarios, SM processes leading to such events have very small production rates. Therefore, this analysis benefits from a small SM background in the signal regions leading to a good sensitivity especially in SUSY scenarios with compressed mass spectra or in which the R-parity is not conserved. The search was performed with cut-and-count analyses exploiting the full dataset recorded with the ATLAS detector at the Large Hadron Collider during the years 2015 and 2016, corresponding to a total integrated luminosity of 36.1 fb$^{-1}$. No significant excess above the Standard Model expectations is observed. The results are interpreted<br>in several simplified supersymmetric models featuring R-parity conservation or R-parity violation, extending the exclusion limits from previous searches.\\<br>Since no sign of SUSY particles has been observed, this dissertation presents prospects for a search for compressed electroweakino production. This supersymmetric scenario is particularly challenging for LHC experiments since the products of the decay chain have low energies and are therefore difficult to detect. <br>Results are obtained with a parameterised simulation of the ATLAS detector performances at a centre-of-mass energy of 14 TeV and for an integrated luminosity of 3000 fb$^{-1}$.\\ | [

The prevailing opinion understands the basic rights in part one of the constitution as a prima facie freedom for every man. The study points out that this broad understanding of freedom does not apply to the arms industry. According to Art. 26(2) of the German constitution weapons designed for warfare may be manufactured, transported or marketed only with the permission of the Federal Government. Details shall be regulated by a federal law. This affects the arms industry's basic rights. They are not established directly by the constitution. Instead they are granted by the federal legislature within certain boundaries and provide only a limited protection against state interference. The Federal Government has a wide discretion to grant or deny a permission. Der Autor untersucht den Zusammenhang zwischen den Grundrechten von Rüstungsunternehmen, die Kriegswaffen herstellen, befördern und in Verkehr bringen, und dem Genehmigungsvorbehalt für diese Tätigkeiten in Art. 26 Abs. 2 GG. Er gelangt zu dem Ergebnis, dass die Verfassung einen Mittelweg zwischen grundrechtlicher Freiheit und effektiver Kriegswaffenkontrolle vorsieht. Dies geschieht durch eine in Art. 26 Abs. 2 Satz 2 GG enthaltene Ermächtigung des Bundesgesetzgebers zur normativen Ausgestaltung der Grundrechte. Die Rüstungsunternehmen haben danach einen grundrechtlichen Anspruch auf ermessensfehlerfreie Entscheidung. Wegen des weiten Ermessens der Bundesregierung besteht jedoch nur im Ausnahmefall ein Anspruch auf eine Genehmigung.

3A797041826.jsonld | Spatial and temporal investigation of localized electric fields in randomly arranged dielectric media | The main research aspect of this thesis is experimental evidence for the spatial and temporal localization dynamics of light in strongly scattering, randomly arranged dielectric media. The physical concept is the Anderson localization, an interference phenomenon based on multiply scattered electromagnetic waves. The localization of light occurs on subwavelength length scales of a few hundred nanometers. For this reason the scattering events occur on timescales of a few femtoseconds. The combination of time-resolved experiments using ultrashort laser pulses and high-resolution optical microscopy to examine the localization properties of nanostructures is the key method and innovation presented in this thesis. It is based on a technique of ultra fast second harmonic microscopy and interferometric autocorrelation. Randomly distributed zinc oxide nano-needles turned out to be well suited for the investigation of the localization of light. The investigation of these nanostructures showed strongly localized photon modes (hotspots) with increased photon mode lifetimes. The fluctuations of the local electric field allow the classification of the localization strength. The localized photon modes can be classified into the regime of strong localization (Anderson localization). This shows that the localization strength and the photon mode lifetime are correlated. Many parameters influence localization, like the diameter of the needles and the distance to another adjacent needle. Therefore, the geometric shape and distribution of the needles scattering the light is crucial for the localization. Furthermore, gold coated zinc oxide nano-needles have been investigated with a higher spatial resolution by using a photo-emission electron microscope (PEEM). It allows the detection of localized electron emission generated by localized light and surface plasmon polaritons. Within this work, the used laser intensities are kept below the threshold to avoid "random lasing" from the sample. Nevertheless even random lasing can be observed by using higher intensities to pump the nano-needle array. By using the above mentioned techniques, we were able to verify the spatial and temporal dynamics of the localization of light for the first time. <engl.> Zentraler Bestandteil dieser Arbeit ist die Untersuchung der Lokalisierung von elektromagnetischen Feldern in zufällig angeordneten dielektrischen Strukturen. Der zugrunde liegende physikalische Prozess der Anderson-Lokalisierung ist die kohärente Vielfachstreuung von Wellen und deren Interferenz. Die auf diese Weise hervorgerufene Lokalisierung erfolgt auf Sub-Wellenlängen Längenskalen, im Falle von Licht im Nanometerbereich. Dabei finden die Streuprozesse auf Zeitskalen von wenigen Femtosekunden statt. Die zeitaufgelöste Untersuchung von Nanostrukturen hinsichtlich ihrer Lokalisierungseigenschaften mit ultrakurzen Laserimpulsen in Verbindung mit hochaufgelöster Mikroskopie stellt die eigentliche Innovation dar. Die experimentelle Verifikation erfolgt unter Verwendung eines 2-Photonen-Mikroskops in Kombination mit einem interferometrischen Autokorrelator. Zufällig angeordnete Zinkoxid-Nanonadeln stellen dabei ein ideales Material zur Untersuchung der raum-zeitlichen Lokalisierungsdynamik von Licht dar. Untersuchungen an diesen Nanostrukturen zeigen dabei stark lokalisierte Photonmoden (Hotspots) mit verlängerten Lebenszeiten im fs-Bereich. Dabei ermöglicht die Untersuchung der räumlichen Feldverteilung und deren Fluktuation die Klassifizierung der Lokalisierungsstärke. Die gemessenen Photonmoden lassen sich somit in den Bereich der starken Lokalisierung einordnen. Dabei sind die Stärke der Lokalisierung und die Lebenszeit der Photonmode miteinander korreliert. Die Stärke der Lokalisierung hängt von vielen Faktoren, wie dem Durchmesser der einzelnen Nadeln sowie deren Abstand zur nächsten Nadel, ab. Dies bezüglich konnte gezeigt werden, dass die geometrischen Eigenschaften der Nadeln und ihre räumliche Verteilung entscheidende Faktoren für die Lokalisierung sind. Des Weiteren wurden goldbeschichtete Zinkoxid-Nanonadeln mit einem Photo-Emissions-Elektronen-Mikroskops (PEEM) untersucht. Diese Methode ermöglicht die Charakterisierung der von den Nadeln emittierten Elektronen und damit die Charakterisierung der lokalen elektrischen Felder mit noch höherer räumlicher Auflösung. Die im Falle dieser Arbeit verwendeten Laser Intensitäten liegen weit unterhalb der Schwelle für einen "random laser", jedoch kann eine solche Probe von Zinkoxid Nanonadeln bei hinreichend hoher Pumpleistung auch zum lasen angeregt werden. Unter Verwendung der zeitaufgelösten 2-Photonen-Mikroskopie konnte zum ersten Mal die raum-zeitliche Dynamik der Lokalisierung von Licht experimentell verifiziert werden. <dt.> | [

3A1046554018.jsonld | Photon-pair generation in photonic crystal waveguides | In this thesis, I overcome the challenges and fill the gaps in knowledge for the design and analysis of photonic crystal slab waveguides (PCSWs) as spontaneous parametric down-conversion (SPDC) sources of photon-pairs, as well as to investigate their potential for engineering the properties of the photon-pair quantum state. I have developed the required formalism for analyzing both the quantum process of SPDC and its classical counterpart of second-harmonic generation (SHG). In studying SHG, I verified my formalism through comparing its results with direct nonlinear simulations. In these formulations, special attention was given to treating lossy modes, as they prove to be an inherent part of the SPDC designs in PCSWs. Moreover, I have found a practical set of PCSW designs, phase-matched for three-wave-mixing processes, while demonstrating that PCSWs can offer a strong control over the phase-matching configuration. This includes reaching phase-matching between modes of different propagation directions, reaching simultaneous phase-matching between multiple processes, and controlling the group velocity of the modes at the point of phase-matching. These capabilities proved to be the key to discovering the unique strength of PCSWs for the SPDC application. Through the use of various phase-matching configurations, I showed how compact SPDC sources can be designed using PCSWs that are capable of creating entanglement and tuning its extent in different degrees of freedom, with specific examples for path and spectral degrees of entanglement, all in a fully integrated way and directly at the generation step. This work also includes my experimental results on characterizing lithium niobate nanostructured ridge waveguides, demonstrating phase-matched SHG. Finally, I propose the concept of atom-mediated SPDC, for interfacing a single-emitter source with a photon-pair source, relying on the bandgap evanescent modes of a periodic waveguide. | [

3A1684701570.jsonld | Untersuchungen zur positionsspezifischen Integration des LTR-Retrotransposons DGLT-A im Genom von Dictyostelium discoideum | Transposable elements (TE) are able to amplify as selfish DNA elements in genomes. Their intrinsic integration can cause insertional mutagenesis of protein-coding genes and challenge their host‘s fitness. To avoid compromising the genome integrity some TEs developed mechanisms for site specific integration. This study describes the molecular mechanism of position specific integration by the LTR retrotransposon DGLT A in the social amoeba Dictyostelium discoideum. In the gene dense haploid genome of D. discoideum DGLT A integrates position specifically 15 bp upstream of tRNA genes. DGLT A uses contacts with the preinitiation complex of RNA polymerase III, which is composed of the complexes TFIIIB and TFIIIC, to identify integration sites upstream of tRNA genes. Yeast two hybrid screening and in vitro pulldown experiments determined that DGLT A uses two retrotransposon encoded proteins to interact with the TFIIIC complex: ribonuclease H (RNH) and integrase (IN). Both proteins interact with TFIIIC subunit Tfc4. Tfc4 contains 12 tetratricopeptide repeats (TPRs) of which TPR1 10 are arranged in a central TPR array. We discovered that DGLT A RNH and IN interact with an interface that covers TPR 7 and 8. A major function of this interface is to connect TFIIIC subcomplexes τA and τB and to facilitate TFIIIB assembly in the RNA polymerase III transcription complex. Thus, we hypothesize that the DGLT A intasome gets access to genomic DNA for integration during tRNA gene transcription by competing with τB for binding at theTPR 7/8 surface in τA. Results from this study suggest that the distantly related amoebozoan D. discoideum LTR retrotransposon DGLT A and the yeast Saccharomyces cerevisiae element Ty3 evolved targeted integration upstream of tRNA genes by convergent evolution. Both retrotransposons solved the problem of finding safe integration sites in compact genomes by targeting to regions close to tRNA genes, but they use different molecular mechanisms to identify their target site 15 bp upstream of tRNA genes. Whereas Ty3 encoded integrase interacts with the TBP/Brf1 heterodimer of TFIIIB suggesting competition of Ty3 during the initiation of POLIII transcription, DGLT A RNH and IN presumably compete with τA/τB interaction during transcription elongation. | [

3A387870016.jsonld | Investigation of the dwarf galaxy population in Hickson compact groups | The nature of compact galaxy groups, which is important concerning the influence of the environment on member galaxies, is largely unknown. In this work dwarf galaxies are investigated in the outer regions of compact galaxy groups in order to determine the evolutionary state of the groups. This is reasonable, because dwarf galaxies are the most common galaxy type and their evolution is influenced by their environment. The results of this work show, that the investigated compact galaxy groups are not chance configurations, but physically bound systems. In all investigated groups dwarf galaxies extend far beyond the density centers of the groups. Further the extension of the groups was estimated and the calculated radii are of the order of 2 Mpc indicating sizes similar to large galaxy groups. This result suggests that compact galaxy groups are centers of larger systems. | [

3A725614579.jsonld | Natur- und sozialwissenschaftliche Analysen anthropogen bedingter Mortalitätsfaktoren und deren Einfluss auf die Überlebenswahrscheinlichkeit des Luchses (Lynx lynx) | Zusammenfassung: The return of large carnivores to the densely populated cultural landscapes of Central Europe represents a major challenge for conservation management. Particularly for the establishment of new populations - through immigration or active reintroduction - human-induced mortality like vehicle collisions or poaching are factors of major concern. This interdisciplinary thesis investigates the key factors for long-term survival and a successful management of lynx (Lynx lynx) by integrating natural scientific and social scientific analyses. The natural scientific part encompassed the analysis of habitat suitability, road mortality and population survival. Models were calibrated using data from the lynx population in the Swiss Jura Mountains and were extrapolated to Baden-Württemberg (BW), Germany, with no current presence of lynx. The social scientific part of the analysis addressed the motivation of hunters for poaching, and was carried out for Germany. Using a logistic regression of telemetry data from lynx in the Swiss Jura Mountains 11 habitat-related variables could be identified which significantly influence the animals’ spatial distribution pattern. Besides slope and human land use, particularly aspect and the distance to roads had the greatest impact on the habitat selection of lynx. Applying the model to BW it could be shown that 10 % of the area is suitable for lynx, which would give room to a population of 108 resident individuals. The most important regions for the establishment of a population are the Black Forest (71 animals) and the Swabian Alb (27 animals). To investigate the specific risk of road sections for lynx, the location of 39 road kills in Switzerland were analysed using logistic regression. Road category, habitat suitability for lynx within 400 meters to both sides of the roads and the distance to urban areas were shown to have a significant effect on the risk of road kills | [

3A630345465.jsonld | Analysis of large-scale metabolic networks : organization theory, phenotype prediction and elementary flux patterns | Analyzing metabolic networks is one of the central topics in systems biology. Thus, different methods for analyzing the structure of such networks have been proposed. The methods used here can be broadly divided into two types: flux-centered approaches like elementary mode analysis (EM analysis), the closely related extreme pathway analysis as well as flux balance analysis (FBA) and approaches like chemical organization theory (OT), that additionally explicitly takes into account metabolites. The aim of this work is the integration of these concepts in order to allow for a more comprehensive analysis of metabolic networks. Indeed, EM analysis and OT can complement each other in two ways. First, the set of chemical organizations of a reaction network allows for a clustering of EMs and helps to identify those EMs that cannot operate at steady state. Second, the set of EMs can be used to compute chemical organizations. In another direction, the combination FBA and EM analysis helps to overcome the problem that the entire set of EMs cannot be computed in large metabolic networks. The framework behind this integration, elementary flux pattern analysis (EFP analysis), allows one to identify all possible routes through a subsystem that are part of a pathway in a genome-scale metabolic network. An important benefit of this concept is that it allows to apply many approaches building on EM analysis to genome-scale metabolic networks. Furthermore, using EFP analysis, we identified several EMs in a subsystem of a metabolic model of Escherichia coli that are not compatible with a pathway on the genome scale. Additionally, we discovered several alternative routes to metabolic pathways in the central metabolism of E. coli. Using EFP analysis in a genome-scale metabolic model of humans we found several pathways that contradict the widely held assumption in biochemistry that the conversion of even-chain fatty acids into glucose is infeasible in humans. | [

Under certain assumptions on the intensity the existence of such a point process is shown. A fundamental example turns out to be the Pólya sum process, whose conditional intensity is a generalisation of the Pólya urn dynamics. A Cox process representation for that point process is shown. A further process considered is a Poisson process of Gaussian loops, which represents a noninteracting particle system derived from the discussion of indistinguishable particles. Both processes are used to define particle systems locally, for which thermodynamic limits are determined. | [

The Kondo effect and the scaling theory of localization are among the fundamental and early discoveries which revealed the novelty hidden in impure or disordered systems. Recent advances in condensed matter physics have emphasized the role of topology, spin-orbit coupling, and certain discrete symmetries such as time reversal in many physical phenomena. These have irreversibly transformed the essential ideas and purview of condensed matter physics, both in theoretical and experimental directions. However, many of these recent developments and their implications are limited to, or by, ideas that pertain to clean systems. This thesis deals with various aspects of these new developments, but in the case of unclean systems.

Up to now no other legal system is familiar with such a general clause. It is therefore neither surprising nor striking that a variety of different meanings has been associated with this general clause, e.g., the duty of solidarity between the contract parties to the inclusion of public interest in the contract. This goes along with its nebulous history. However, the courts focus on one specific meaning, to wit, the judicial revision of contracts.This dissertation, therefore, compares the judicial revision of contracts in Brazilian law with the judicial revision of contracts according to § 313 BGB. On basis of her comparative investigation the author discusses the cultural dimension of Brazilian law and its characteristics, to wit, flexibility, the animosity towards private autonomy, the role of consumer law and the so called “constitutionalisation” of civil law. Das neue brasilianische Zivilgesetzbuch von 2002 hat als Generalklausel des allgemeinen Vertragsrechts die soziale Funktion des Vertrages (Art. 421) eingeführt.

3A1024670759.jsonld | Key players : selected chemosensory sensilla in the tobacco hawkmoth Manduca sexta | The natural environment of insects comprises a variety of volatile chemical signals that provide essential information about intraspecific communication, host plant location, suitability of oviposition sites or presence of natural enemies. The detection of volatile cues by sensory neurons on chemosensory organs is thus a fundamental process to ensure the survival of an insect. The aim of this thesis was to investigate the peripheral chemosensory system on a molecular and functional level. For this approach we employed the tobacco hawkmoth Manduca sexta as a valuable model organism, which has been studied intensively from various aspects like morphology, physiology, ecology and olfactory guided-behaviors. The main chemosensory organ is the antenna, which bears several types of olfactory sensilla. These sensilla contain dendrites of olfactory sensory neurons (OSNs) in which the chemosensory receptors are expressed. Three major families of chemosensory receptors have been described in insects: olfactory receptors (ORs), ionotropic receptors (IRs) and gustatory receptors (GRs), which include CO2 receptors. By generating a high-quality genomic data set for M. sexta (manuscript I), accompanied by RNAseq data from several chemosensory tissues we could establish an excellent chemosensory receptor reference gene set (manuscript II). In this process we improved and corrected gene models, and verified receptor genes by cloning. In total, we identified 73 ORs, 21 IRs and 2 CO2 receptors in M. sexta. The reference gene set provides a base for further comparative genomic approaches and may support the identification of new chemosensory receptor genes in other species. Our analysis revealed that M. sexta has one of the largest antennal IR repertoires found in lepidopteran species. In contrast to the divergent ORs, IRs are far more conserved, which suggests that the functions of IRs seem to be conserved as well. Olfactory IRs are usually expressed by sensory neurons housed in coeloconic sensilla. Since no previous study was conducted on functional characterization of coeloconic sensilla on the antenna of M. sexta, we determined ligand profiles for this type of olfactory sensillum (manuscript III). By using electrophysiological measurements we could demonstrate that OSNs of coeloconic sensilla on the antenna of M. sexta respond predominantly to acids, amines and aldehydes, highly matching the ligand profiles of coeloconic sensilla of D. melanogaster, but not to its other olfactory sensillum types. Similar results were obtained in electrophysiological studies on other lepidopteran species. This indicates that the function of coeloconic sensilla in the detection of such substances is conserved. ... | [

3A864720483.jsonld | Child migration and educational progression in the Savannah regions of Ghana : Implications for planning and spatial development | Child migration in Ghana has moved beyond the concerns of individual child migrants and their families, to one of national development concerns. Streets, pavements and other public spaces in the cities and towns - especially Accra - are flooded with children engaged in various activities. These children are not only a nuisance to road users and city authorities, but exert pressure on social amenities as well as threat to security. However, little is known about the education of children when they migrate. This requires research attention, to shed light on the phenomenon. In this study, I explore the motivations for migration of children from Bongo district to Accra in Ghana and examine how migration influences their pursuit of basic education. The study employed a mixed methods design involving observation, interviews with 35 child migrants, community discussions, interviews with experts and schedule officers of government and non-governmental organisations working on issues of child migration. Furthermore, questionnares were administred to 490 (250 migrant and 240 non-migrant) children in 10 schools in the district and their academic performance data obtained and analysed, using Mann-Whitney U Test, to find differences in their performance. Poverty, peer influence and pursuit of education emerged as major motivational factors, while non-migrant school children performed relatively better than their migrant counterparts. Nevertheless, the overall effects of migration on education was found to be mixed. Whereas it was negative or positive for some, others pursued apprenticeship as an alternative. I conclude that children in deprived regions migrate to escape unfavourable living conditions and to accumulate wealth in urban areas. However, involvement in migration has negative effects on performance in class with the likelihood of stalling progress in education. Furthermore, I recommend affirmative action by national and local government actors, in order to reduce poverty in rural areas while confronting the daunting challenges in rural schools to improve access and quality. | [

3A1837639701.jsonld | Sensor-based human activity recognition for assistive health technologies | The average age of people has increased due to advances in health sciences, which has led to an increase in the elderly population. This is positive news, but it also raises questions about the quality of independent living for older people. Clinicians use Activities of Daily Living (ADLs) to assess older people's ability to live independently. In recent years, portable computing devices have become more present in our daily lives. Therefore, a software system that can detect ADLs based on sensor data collected from wearable devices is beneficial for detecting health problems and supporting health care. In this context, this book presents several machine learning-based approaches for human activity recognition (HAR) using time-series data collected by wearable sensors in the home environment.In the first part of the book, machine learning-based approaches for atomic activity recognition are presented, which are relatively simple and short-term activities. In the second part, the algorithms for detecting long-term and complex ADLs are presented. In this part, a two-stage recognition framework is also presented, as well as an online recognition system for continuous monitoring of HAR.In the third and final part, a novel approach is proposed that not only solves the problem of data scarcity but also improves the performance of HAR by implementing multitask learning-based methods. The proposed approach simultaneously trains the models of short- and long-term activities, regardless of their temporal scale. The results show that the proposed approach improves classification performance compared to single-task learning | [

3A1667708643.jsonld | Religion - marketing's unwitting godparent : a case study of coffee branding and consumer loyalty | This book provides an in-depth understanding of the analogy between marketing and religion: how an effective marketing campaign makes consumers construct an entire worldview with a corresponding ethos regarding an advertised commodity, which results in exceptional consumer loyalty and high profit margins. This book scrutinises the advertising campaign ‘Nespresso. What else?’. The study is based on an audio-visual analysis of selected commercials, and on an analysis based on primary data about Nespresso drinkers and, as a control group, about consumers of other coffee brands. The statistically highly significant results are impressive and to some degree disturbing. They shed light on how the exchange value of a profane consumer item is increased to a multiple of its use value and how, in accordance with Walter Benjamin’s thesis, the symbolic charging of a commodity, stripped of its profane attributes, is taken to extremes. Dieses Buch vermittelt ein tiefes Verständnis der Analogie zwischen Marketing und Religion. Konsument*innen werden mit nahezu perfekter Werbung dazu angeregt, bezüglich des beworbenen Produkts ein Weltbild mit dazu passendem Ethos zu konstruieren. Extreme Kundenloyalität und hohe Gewinnmargen sind die Folgen. Untersucht wird die Werbekampagne „Nespresso. What else?“. Die Studie basiert auf einer audio-visuellen Analyse ausgewählter Werbespots und auf einer Analyse von Primärdaten von Nespresso-Kund*innen sowie, als Kontrollgruppe, von Konsument*innen anderer Kaffee-Marken. Die statistisch hoch signifikanten Ergebnisse sind eindrücklich und machen betroffen. Sie vermitteln ein Verständnis dafür, wie der Tauschwert eines an sich profanen Konsumguts auf ein Vielfaches seines Gebrauchswerts gesteigert werden kann, und wie, ganz im Sinne Walter Benjamins, losgelöst von nüchternen Produktattributen, ein Produkt eine äußerst starke symbolische Aufladung erfährt. | [

3A1774349639.jsonld | Struktur und Grenzen des Missbrauchsbegriffs : zur Frage der Heranziehung außerkartellrechtlicher Rechtsverstöße zur Begründung des Missbrauchsvorwurfs | Christian Schönberger gives a basic definition of the determinants for the interpretation of the prohibition of abuse of a dominant position in antitrust law. What is the significance of a statutory violation within the framework of the established – competition-related – concept of abuse, and does the previous teleology have to be broadened as the circumstances require? VBL-Gegenwert, Pechstein, Facebook – zur Begründung des Missbrauchs einer marktbeherrschenden Stellung wurden zuletzt zunehmend außerkartellrechtliche Wertungen wie die des AGB-Rechts, der Grundrechte oder des Datenschutzrechts herangezogen. Doch aus welchem Grund sollte ein Verstoß eines marktbeherrschenden Unternehmens gegen eine Vorschrift, die mit dem Kartellrecht zunächst einmal nichts zu tun hat, auch einen kartellrechtlichen Unwert im Sinne von Art. 102 AEUV bzw. § 19 GWB beinhalten? Christian Schönberger widmet sich der grundsätzlichen Bestimmung der Determinanten für die Auslegung des Missbrauchsverbots. Ist zur Gewährleistung des Normzwecks der Nachweis einer Ausbeutung der Marktgegenseite bzw. einer Behinderung der Wettbewerber anhand einer plausiblen ökonomischen Schadenstheorie unabdingbar? Oder kann aufgrund der damit verbundenen Nachweisschwierigkeiten auf Bewertungsmaßstäbe ohne näheren Wettbewerbsbezug zurückgegriffen werden? | [

3A664340873.jsonld | Public liability in EU law : Brasserie, Bergaderm and beyond | "Over the last two decades public law liability for breach of European Union law has been subject to remarkable developments. This book examines the convergence between its two constituent systems: the damages liability of the EU and that of its Member States for failing to comply with EU rules. Member State liability, based as it is on the Francovich case (1991) and Brasserie du Pêcheur and Factortame (1996) judgments of the European Court of Justice (ECJ) is well established. But it is yet to be closely scrutinised by reference to the detailed rules on the liability of the European Union. The focus of the book is on the two key legal criteria that are common to both systems, namely the grant of rights to individuals by EU law and the notion of sufficiently serious breach of such rights. The analysis concentrates on developments in the case law of the ECJ and the General Court since the Bergaderm judgment (2000), which consolidated the convergence of the two liability systems that was first indicated in Brasserie du Pêcheur and Factortame. These two criteria are set side by side to evaluate the extent, in real terms, of the convergence of Member State and EU institutional damages liability, and to determine the extent to which one has influenced the other. This book shows that although full convergence between the two liability systems is not likely, each stream of case law should look to the other more actively as this important element of EU remedial law develops. Convergence in EU law public liability is supported by developments in adjacent areas, most notably European tort law and European administrative law. This study also illustrates how convergence in the EU liability systems to date has had spill-over effects into national public liability law"--Provided by publisher | [

3A1685628346.jsonld | Assessment of individual- and group-level behavioral variation in dairy cattle : from personality to social networks | Currently little consideration is given to individuality and social behavior when managing dairy cow groups. This thesis assessed three objectives: 1) Investigating personality in adult lactating cows, 2) comprehensive analysis of social networks in a free-stall barn, 3) facilitating the automated assessment of agonistic behavior. Findings suggest that the level of individuals and the level of social groups should also be taken into account when assessing dairy cattle welfare. The presented automatic method for detecting agonistic behavior and dominance is one important step in this direction.<eng> | [
