3A1008606138.jsonld | Sanierungsgeschäftsführung in Krise und Eigenverwaltung : Kompetenzen und Haftung der GmbH-Geschäftsführung nach dem ESUG | The author analyzes the competences and liabilities of managing directors in a corporate crisis as well as in self-administrated insolvency proceedings and gives his view on further questions raised by the more recent legislative reform. In particular, the reform of the insolvency law by the ESUG of 2012, which promotes restructurings and self-administrated proceedings, raised various questions leading to uncertainty in practice on all sides. Those relate to insolvency law such as questions on the judicial competences regarding applications for self-administrated proceedings or the self-administrating debtor’s right to create debts of the insolvency assets. Particularly, the relation between insolvency law and corporate law needs to be reconsidered which has direct impact on the competences and liabilities of managing directors in a corporate crisis and self-administrated proceedings. The author’s position on these questions is expressed in this book. Der Verfasser untersucht die Kompetenzen und die Haftung von Geschäftsführern in der Unternehmenskrise sowie im Insolvenzverfahren in Eigenverwaltung und nimmt zu weiteren durch die jüngeren Gesetzesreformen aufgeworfenen Fragen Stellung. Gerade die Insolvenzrechtsreform durch das ESUG im Jahr 2012, die Sanierungen und insbesondere das Eigenverwaltungsverfahren fördert, hat viele Fragen aufgeworfen, die in der Praxis zur Verunsicherung auf allen Seiten führen. Diese sind etwa insolvenzrechtlicher Natur wie die Prüfungskompetenzen des Insolvenzgerichts bei Anträgen auf Eigenverwaltung oder das Recht des eigenverwaltenden Schuldners zur Begründung von Masseverbindlichkeiten. Vor allem aber muss das Verhältnis zwischen Insolvenzrecht und Gesellschaftsrecht neu bewertet werden, welches unmittelbare Auswirkungen auf die Kompetenzbereiche und die Haftung der Geschäftsführung in der Krise und im Eigenverwaltungsverfahren hat. Zu diesen Fragen wird in der vorliegenden Arbeit Stellung genommen. | [

3A775976865.jsonld | Competition mechanisms of native and exotic tree species | The amount of exotic plant species introduced to new regions by humans has considerably increased in the last two centuries. Worldwide, the invasion of exotic species represents an important threat to native biodiversity and ecosystem functions. Several biological traits (e.g., high growth rate and rapid propagation) result in a superior competitiveness of invasive species and often cause changes in natural species composition. Specifying the attributes that turn exotic species into strong competitors may improve the ability to understand and effectively manage plant invasions in the future...

Weltweit gefährdet die Invasion von Neophyten beträchtlich die einheimische Biodiversität und Ökosystemfunktionen. Verschiedene biologische Eigenschaften (z.B. hohe Zuwachsrate und schnelle Vermehrung) führen zu einer besseren Konkurrenzfähigkeit von invasiven Arten und verursachen Veränderungen in der natürlichen Artzusammensetzung.

3A1657025632.jsonld | Strangeness and Charge Symmetry Violation in Nucleon Structure | This thesis discusses two key topics: strangeness and charge symmetry violation (CSV) in the nucleon. It also provides a pedagogical introduction to chiral effective field theory tailored to the high-precision era of lattice quantum chromodynamics (QCD). Because the nucleon has zero net strangeness, strange observables give tremendous insight into the nature of the vacuum; they can only arise through quantum fluctuations in which strange–antistrange quark pairs are generated. As a result, the precise values of these quantities within QCD are important in physics arenas as diverse as precision tests of QCD, searches for physics beyond the Standard Model, and the interpretation of dark matter direct-detection experiments. Similarly, the precise knowledge of CSV observables has, with increasing experimental precision, become essential to the interpretation of many searches for physics beyond the Standard Model. In this thesis, the numerical lattice gauge theory approach to QCD is combined with the chiral perturbation theory formalism to determine strange and CSV quantities in a diverse range of observables including the octet baryon masses, sigma terms, electromagnetic form factors, and parton distribution functions. This thesis builds a comprehensive and coherent picture of the current status of understanding of strangeness and charge symmetry violation in the nucleon.

3A100277151X.jsonld | The collateral framework of the Eurosystem and its fiscal implications | This thesis was written by Jakob Eberl while having been a research assistant at the Center for Economic Studies (CES) at the University of Munich. It was completed in December 2015 and accepted as a doctoral thesis by the Department of Economics at the University of Munich in May 2016. The thesis tells the story of the Eurosystem's collateral framework and its fiscal implications in seven chapters (neglecting the introduction and the conclusion), which can be conceptually assigned to two parts. Die vorliegende Arbeit wurde von Jakob Eberl während seiner Tätigkeit als Wissenschaftlicher Mitarbeiter am Center for Economic Studies (CES) an der Ludwig-Maximilians-Universität (LMU) München erstellt. Sie wurde im Dezember 2015 abgeschlossen und von der Volkswirtschaftlichen Fakultät der LMU München als Dissertation angenommen. Die Arbeit beschäftigt sich mit dem Sicherheitenrahmen des Eurosystems und dessen fiskalischen Implikationen. Sie umfasst sieben Kapitel (ohne Einleitung und Schluss), die in zwei Teile gegliedert werden können. Der erste Teil beinhaltet die Kapitel 2 bis 5 und analysiert den Sicherheitenrahmen des Eurosystems. Kapitel 2 gibt eine Einführung in die Entwicklung der Geldpolitik des Eurosystems während der Finanz- und Staatsschuldenkrise. Die Pfänderkriterien des Eurosystems werden dabei als essentiell für das Umsetzen dieser Geldpolitik identifiziert. Kapitel 3 präsentiert eine umfassende Analyse der im Sicherheitenrahmen des Eurosystems verankerten Pfänderkriterien, indem es eine narrative Datenbank von allgemeinen Prinzipien und Änderungen erstellt. Darüber hinaus werden Effekte von Änderungen der Pfänderkriterien auf die notenbankfähigen Sicherheiten („Sicherheitenpool“) hinsichtlich verschiedener Aspekte herausgearbeitet. Kapitel 4 beschäftigt sich mit der Risikokontrolle des Eurosystems und legt dar, wie diese in den vergangenen Jahren angepasst wurde. Ferner werden Schwächen der Risikokontrolle aufgezeigt. Kapitel 5 untersucht Effekte der Pfänderkriterien und der Risikokontrolle, indem es die Entwicklung der Bonität der dem Eurosystem verpfändeten Sicherheiten nachvollzieht. Das innerhalb dieses Kapitels erarbeitete Modell zeigt, dass Banken Sicherheiten minderer Qualität dem Eurosystem verpfänden, während qualitativ hochwertige Sicherheiten am Markt genutzt werden („adverse Selektion von Pfändern“). Der zweite Teil der Dissertation umfasst die Kapitel 6 bis 8 und untersucht die fiskalischen Implikationen des Sicherheitenrahmens. Kapitel 6 entwickelt das Instrumentarium zur Analyse der fiskalischen Implikationen, welche vor dem Hintergrund der fiskalischen Tragfähigkeit durchgeführt wird. Das Erweitern des Konzepts der fiskalischen Tragfähigkeit um Unsicherheit ermöglicht das Formulieren eines intuitiven Indikators zur Beurteilung der fiskalischen Implikationen. Kapitel 7 untersucht die fiskalische Implikation, die aus der Bedeutung dieser Kriterien für die finanzielle Lage einer Notenbank und der engen Verbindung zwischen dieser finanziellen Lage und dem Staatshaushalt resultiert. Das Kapitel bestimmt ein aus fiskalischer Sicht optimales Niveau der Pfänderkriterien und zeigt, dass einheitliche Pfänderkriterien in einer Währungsunion aus heterogenen Staaten länderübergreifende fiskalische Implikationen bergen. Kapitel 8 adressiert die fiskalische Implikation, die aus der Bedeutung der Kriterien für den Anreiz eines Staates explizite Garantien auszusprechen, resultieren. Das Kapitel zeigt, dass der Sicherheitenrahmen des Eurosystems Spielraum für Staaten birgt, notenbankfähige Sicherheiten durch explizite Garantien zu schaffen. Dieser Spielraum muss berücksichtigt werden, wenn das aus fiskalischer Sicht optimale Niveau expliziter Staatsgarantien bestimmt wird. Abschließend schlägt die Dissertation auf Basis der gewonnenen Ergebnisse Verbesserungen der im Sicherheitenrahmen des Eurosystems verankerten Pfänderkriterien und Risikokontrolle vor. | [

Based on Niklas Luhmann's social theory of politics, Thorsten Hasche investigates three central movements of Sunnite Islamism in the AKP, al-Qaida and the Muslim Brotherhood. Historically and comparatively, he considers their thought leaders, their political ideologies and their structures. It becomes clear that Sunnite political Islam will remain a powerful presence in global political systems, at least in the medium term. Sowohl der »Arabische Frühling« als auch das Erstarken der dschihadistischen Kampfgruppe »Islamischer Staat« haben die diversen islamistischen Bewegungen in den Fokus der medialen und publizistischen Aufmerksamkeit rücken lassen. Auf der Basis der Gesellschaftstheorie der Politik Niklas Luhmanns untersucht Thorsten Hasche mit der AKP, der al-Qaida und der Muslimbruderschaft drei zentrale Bewegungen des sunnitischen Islamismus. Historisch und vergleichend nimmt er dabei ihre Vordenker, ihre politischen Ideologien und ihre Strukturen in den Blick. Es wird deutlich: Der sunnitische politische Islam wird auch mittelfristig ein wirkmächtiger Bestandteil des weltpolitischen Systems bleiben. | [

3A1759389544.jsonld | The Modern Greek dialect of the Karagouns in West Thessaly | The theme of this dissertation is the research, prescription and examination of the modern Greek dialect of the Karagouns, a Greek population in West Thessaly, Greece. The geographical center of the dialect coincides with the central area of the geographical distribution of the population. It includes communities in the prefecture of Karditsa, which were located around the large marsh, now drained, almost at the centre of the plain of West Thessaly. The informants were elderly males and females who lived permanently in their villages, had not moved for a long time and were involved in the traditional occupations of the Karagouns. The research and the material collection took place in the physical premises of the informants, in their home or in the workplaces (field, pastoral place) where they felt comfortable and could speak without showing any tendency to correct their speech. The material recorded constitutes the sources for this linguistic and dialectological research. The goal of the thesis is to give a comprehensive prescription and analysis of the grammar and to examine other dialectological fields such as vocabulary, loans from other languages and the relation of the Karagoun dialect to other varieties in Thessaly. In the first part of this thesis, the nomination of the population is examined; the geographical, historical and cultural elements which also form their identity in Thessaly. In the second part all grammatical fields are examined. The analysis is developed in two axes, a synchronic approach particularly in phonetics and phonology and a diachronic view which attempts to document the relationship between this dialect and other northern Greek dialects. In the third part, archaisms contributing to the research of the relationship between Modern Greek dialects and medieval and ancient Greek are presented. In the fourth part, loans from foreign languages and Balkanisms are examined and quoted, since the Karagoun dialect is part of the Balkansprachbund. | [

3A1653710942.jsonld | Gesteuerte Gesundheit : Grund und Grenzen verhaltenswissenschaftlich informierter Gesundheitsförderung und Krankheitsprävention | Public health policy can contribute significantly to the improvement of an individual’s health. But how and by which means can this goal be achieved? Under the influence of behavioural economics, allegedly “mild” regulatory instruments such as incentives and nudges are increasingly being used to influence individual behaviour. However, the use of behavioural economics in public health regulation can threaten individual freedoms; the state should be required to justify such regulatory action. But is it the state’s responsibility to improve the health of the individual? In order to answer this question, this dissertation examines the rationale behind public health policy, systemises the different regulatory instruments used to influence individual health behaviour, and reveals their potential to interfere with personal freedoms. Thereafter, it sheds light on the possible justifications for such state actions. Eine gesundheitsfördernde Politik kann einen wesentlichen Beitrag zur Verbesserung der Bevölkerungsgesundheit leisten. Doch wie und mit welchen Mitteln kann dieses Ziel erreicht werden? Unter Einfluss verhaltensökonomischer Erkenntnisse rücken zunehmend vermeintlich freiheitsschonende Instrumente individueller Verhaltenssteuerung wie etwa Anreize und sog. Nudges in den Fokus der Debatte.Die verhaltensökonomisch informierte Steuerung im Gesundheitswesen stellt jedoch eine Freiheitsgefährdung dar. Der Staat bedarf damit guter Rechtfertigungsgründe. Doch ist es seine Aufgabe, über die bloße Krankenversorgung hinaus für die Gesundheit Einzelner zu sorgen? Zur Beantwortung dieser Frage werden nach Aufarbeitung der gesundheitspolitischen Hintergründe die präventiven gesundheitspolitischen Steuerungsinstrumente systematisiert und ihr Eingriffspotential aufgezeigt. Sodann werden der damit ausgelöste Rechtfertigungsbedarf und die in Frage kommenden Rechtfertigungsmöglichkeiten untersucht. | [

3A1015216838.jsonld | A framework for incremental view graph maintenance | Nowadays, graph data models are employed, when relationships between entities have to be stored and are in the scope of queries. For each entity, this graph data model locally stores relationships to adjacent entities. Users employ graph queries to query and modify these entities and relationships. These graph queries employ graph patterns to lookup all subgraphs in the graph data that satisfy certain graph structures. These subgraphs are called graph pattern matches. However, this graph pattern matching is NP-complete for subgraph isomorphism. Thus, graph queries can suffer a long response time, when the number of entities and relationships in the graph data or the graph patterns increases. One possibility to improve the graph query performance is to employ graph views that keep ready graph pattern matches for complex graph queries for later retrieval. However, these graph views must be maintained by means of an incremental graph pattern matching to keep them consistent with the graph data from which they are derived, when the graph ... | [

3A1702144879.jsonld | Gesetzlich bestimmte Strafbarkeit des Eigendopings : Formelle und materielle Implikationen des Verfassungsrechts für das Strafrecht | To fight doping in sport, Germany enacted a new anti-doping law in 2015. Its novel regulation of making self-doping an offence is considered a success by the legislator. But is the state even allowed to prohibit athletes from doping themselves – and then punish them for it? Trotz jahrzehntelanger Bemühungen vermochten sportrechtliche Anti-Doping-Maßnahmen die Dopingproblematik im Sport nicht in den Griff zu bekommen. Verständlich ist es daher, dass sich der Gesetzgeber zum Einschreiten berufen sah und im Jahr 2015 das Anti-Doping-Gesetz (AntiDopG) erließ. Mit der darin neu geschaffenen Strafbarkeit des Eigendopings sieht er sich in einer Vorreiterstellung. Zu Recht? Darf der Staat den Sportlerinnen und Sportlern verbieten, sich selbst zu dopen – und dies gar mit Strafe bewehren? Verena Groß entwickelt Antworten auf diese Fragen im Rahmen eines grundlagenorientierten, akzessorischen Strafrechtssystems. Anhand der Strafbarkeit des Eigendopings nach dem AntiDopG erarbeitet sie exemplarisch die verfassungsrechtlichen Anforderungen, die bei der Schaffung neuer und bei der Analyse bereits bestehender Strafvorschriften zu beachten sind. | [

3A1004871317.jsonld | Transport properties of LaAlO3/SrTiO3 nanostructures | The quasi two-dimensional electron gas (2DEG) at the interface of two band insulators (LaAlO3 and SrTiO3) has very intriguing properties like high mobility, induced ferromagnetism and superconductivity. In this study, an industry compatible nano-patterning technique is developed, to pattern the LaAlO3/SrTiO3 interface down to 100 nm by using e-beam lithography and reactive ion etching (RIE). The process preserves the conductivity of interface, except a narrow depletion region. Moreover, in the nanostructures, the correlation between the interface conductivity and local structure of the SrTiO3 is studied. At low temperature structural phase transition of SrTiO3 leads to formation of domains within SrTiO3. These domains modulate the conductivity of the LaAlO3/SrTiO3 interface and the current is no more homogeneous within the domains, rather it flows in filaments at the boundaries of the domains and leaving the domain area basically insulating. Oxide materials; electron gas; band insulator; lithography; reactive ion etching (RIE); domains; structural transition; domain walls Das quasi-zweidimensionale Elektronengas (2DEG) an der Grenzfläche zweier Bandisolatoren (LaAlO3 und SrTiO3) hat sehr faszinierende Eigenschaften wie hohe Mobilität, induzierter Ferromagnetismus und Supraleitung. In dieser Studie wird eine industrietaugliche Nanostrukturierungstechnik entwickelt, um mittels Elektronenstrahllithographie und reaktives Ionenätzen (RIE) eine LaAlO3/SrTiO3-Grenzfläche auf 100 nm zu strukturieren. Der Prozess bewahrt die Leitfähigkeit der Grenzfläche mit Ausnahme einer schmalen Verarmungszone. Zudem wird in den Nanostrukturen die Korrelation zwischen Grenzflächenleitfähigkeit und der lokalen Struktur von SrTiO3 untersucht. Bei niedriger Temperatur führt der strukturelle Phasenübergang von SrTiO3 zur Bildung von Domänen innerhalb von SrTiO3. Diese Domänen modulieren die Leitfähigkeit der LaAlO3/SrTiO3 -Grenzfläche, und der Strom ist innerhalb der Domänen nicht mehr homogen, sondern fließt in Filamenten an den Grenzen der Domänen.

3A1656907593.jsonld | Die Kompetenzverteilung zwischen Justiz und Jugendhilfe bei Entscheidungen zu erzieherischen ambulanten Maßnahmen im JGG, insbesondere § 10 JGG : eine rechtliche und empirische Untersuchung mit Reformvorschlag | The book aims to contribute to the current discussion on criminal politics in German theory and practice. Focusing on the controversial relations between juvenile criminal justice and youth welfare, this PhD project provides a new perspective on questions of discretionary competence regarding ambulant socio-educational measures for juvenile offenders – educational and disciplinary measures or the so-called ‘Hilfen zur Erziehung’. Bearing crucial practical implications, the thesis tackles the question of who is in charge of carrying out and financing such ambulant measures as imposed by juvenile court. In addition to analyzing the legal-theoretical background of the cooperation between justice system and youth welfare, the author puts forward an empirical study evaluating its practice and develops a potential reform proposal. The study is aimed at scientific and political audiences as well as practitioners in the German juvenile criminal justice system and youth welfare. Die Arbeit liefert einen Beitrag für die aktuelle kriminalpolitische Diskussion in Wissenschaft und Praxis zum umstrittenen Verhältnis von Jugendstrafjustiz und Jugendhilfe. Sie beschäftigt sich mit der bislang noch kaum ausführlich bearbeiteten, jedoch für die Praxis äußerst relevanten und seit Jahren diskutierten Frage der Entscheidungskompetenz bei erzieherischen ambulanten Maßnahmen – den Weisungen und Auflagen bzw. den Hilfen zur Erziehung. Konkret betrifft dies die ungeklärte Frage der Durchführung und Finanzierung der durch das Jugendgericht verhängten ambulanten Maßnahmen. Neben einer rechtlichen Analyse der rechtstheoretischen Grundlagen der Zusammenarbeit von Justiz und Jugendhilfe sowie des Streitgegenstandes umfasst die Arbeit eine empirische Untersuchung zur Evaluation der Praxis sowie einen eingehend begründeten Reformvorschlag zur Auflösung des Konfliktfeldes. Sie richtet sich sowohl an Wissenschaft und Politik als auch an Praktiker in Jugendstrafjustiz und Jugendhilfe. | [

3A1801213011.jsonld | Elektrisch angesteuerte Gold-Polymer-Gold-Ultrafiltrationsmembranen zur Aufbereitung NOM-haltiger Wässer | Humanity is facing a water crisis due growing water demand of an increasing population, economic development, water pollution, and climate change. Ultrafiltration (UF) is a promising technology for countering the global water crisis due to its high removal potential for pathogens and turbidity at high recovery and low demand of chemicals. However, it suffers from membrane fouling and low removal performance for organic water constitutes such as natural organic matter (NOM). The selectivity for NOM increases when the pore size of the UF membrane is decreased but this also leads to reduction of permeability and energy efficiency. This problem is called the selectivity-permeability trade-off. Electrically conductive UF membranes are a new approach which might offer a solution to these problems. Most NOM are negatively charged. By application of a negative or positive electrical potential to the membrane surface, a repulsive or attractive force is induced on the charged substances in the feed water, respectively, which influences the rejection and fouling behavior of these membranes. In this work, an ultra-thin gold coating was applied on the active and support layer of flat-sheet polymer membranes to achieve electrical conductivity. Due to the coating of both sides of the membrane, no additional counter electrode was necessary to apply an external potential. An intrinsically negatively charged polyethersulfone (PES, UP150) and an intrinsically positively charged polyamide (M5) membrane were used for electro-repulsive and electro-sorptive filtration experiments, respectively. In the first part of this thesis, the membranes were characterized before and after the gold-coating regarding its filtration and electrochemical properties. Sputter coating only slightly changed the filtration properties of the membranes. The molecular weight cut-off was almost not affected by the gold coating. However, the pure-water permeability was reduced by 15 % and 40 % for the M5 and UP150 membrane, respectively. In the second part of this thesis, electro-repulsive filtration was conducted with model NOM solutions and natural lake water with the UP150 membrane. At filtration of Hohloh lake water the permeability decreased by 49 % (± 2 %) when no external potential was applied (0 V). However, when negative potential was applied the permeability only decreased by 17 % (± 3 %) (at -2.5 V). The application of negative potential to the membrane active layer led to less fouling and an increased NOM rejection at cross-flow mode. The molecular weight cut-off was shifted from 150 kDa at no applied potential to 5 kDa at -2.5 V (cell potential). Therefore, it could be seen that the duplex-coated membrane configuration was almost as effective as conventional counter electrode configuration in fouling mitigating and rejection enhancement. In the third part, electro-sorptive dead-end filtration experiments showed that the application of a positive potential led to adsorption of NOM and negatively charged organic dye molecules. When the potential was reversed to negative potential, the previously adsorbed substances could be desorbed. The process of electrosorptive UF worked with the intrinsically positively charged M5 membrane but not with the intrinsically negatively charged UP150. The molecular weight cut-off of the M5 membrane was shifted from approx. 1000 kDa at no applied potential to approx. 0.7 kDa at +2.5 V (cell potential). Therefore, the electrosorptive UF achieved a NOM rejection performance in the range of commercially available nanofiltration membranes. At the same time, the positively charged M5 membrane showed permeability in the range of loose UF membranes and fouling was not observed to be problematic. The additional energy consumption for the application of the external potential was low with 0.03 kWh/m³ of permeate. Overall, electro-repulsive and electro-sorptive UF membranes, both, broke the selectivity-permeability trade-off of the UF process. Whereas, the electrosorptive enhancement of NOM removal was more pronounced than the electro-repulsive. Weltweit steigt der Wasserbedarf aufgrund von Bevölkerungszuwachs, wirtschaftlicher Ent-wicklung, Verschmutzung von Wasserressourcen und dem Klimawandel. Die Ultrafiltration (UF) ist eine vielversprechende Technologie zur Aufbereitung von Trinkwässern und Recycling von Abwässern, welche zur Lösung des globalen Problems der Wasserverknappung beitragen kann. Jedoch unterliegen UF-Membranen dem Problem des Foulings und zeigen einen nur geringen Rückhalt für gelöste Wasserinhaltsstoffe, insbesondere organische Substanzen. Das Trennverhalten von UF-Membranen wird einerseits von der Po¬rengrößenverteilung bestimmt, jedoch auch von der elektrischen Ladung der Membran. Generell gilt, dass mit zunehmendem Rückhalt von natür¬lichen organischen Wasserinhaltsstoffen (NOM) auch die Permeabilität der Membran abnimmt, was zu einem erhöhten spezifischen Energiebedarf führt. Dieser Zusammenhang wird als Selectivity-Permeability-Trade-off bezeichnet. Voran-gegangene Studien zeigten, dass Membranen, welche eine negative Ladung aufweisen, zu weniger Fouling und höheren NOM-Rückhalten neigen. Dies wird auf die negative Ladung der NOM und die daraus resultierende elektrostatische Abstoßung dieser von der Membran-oberfläche zurückgeführt. Durch die Erzeugung einer ultra¬dünnen leitfähigen Schicht auf der Oberfläche einer UF-Membranen, ist es möglich ein externes elektrisches Potential an UF-Membranen anzulegen und somit Einfluss auf das Filtrationsverhalten der Membran zu nehmen, indem die elektrostatischen Wechselwirkungen verstärkt werden. Im ersten Teil dieser Arbeit wurden zwei kommerzielle UF-Membranen auf der Trenn- und Stützschicht mit einer ultradünnen Goldschicht besputtert (15 bzw. 40 nm). Dafür wurden eine intrinsisch negativ geladene (Polyethersulfon, UP150) und eine intrinsisch positiv geladene (Polyamid, M5) UF-Membran verwendet. Die Membranen wurden zunächst im unbeschichteten und dann im beschichteten Zustand charakterisiert. Hierbei wurden u. a. die Permeabilität, die elektrische Leitfähigkeit, die Hydrophilie, die BET-Oberfläche, das Zetapotential sowie der elektroosmotische Fluss untersucht. Durch die Sputterbeschichtung wird auf der Trennschicht der Membranen eine vergleichsweise hohe elektrische Leitfähigkeit generiert, wobei die Permeabilität sowie die Trennleistung der UP150 und M5-Membran weitgehend erhalten bleibt. Im zweiten Teil dieser Arbeit wurden Versuche zur elektrorepulsiven UF im Crossflow-Betrieb durch¬geführt. Dabei wurde gezeigt, dass sich NOM-Fouling vermindern und der NOM-Rückhalt stei¬gern lässt, wenn ein negatives Potential an die Membran angelegt wird. Ohne das Anlegen eines Potential (0 V) nimmt die Permeabilität während der Filtration von Hohlohsee-wasser um 49 % (± 2 %) ab, wobei beim Anlegen eines negativen Potentials (-2,5 V) die Permeabilität lediglich um 17 % (± 3 %) absinkt. Gleichzeitig führt die gesteigerte elektro-repulsive Absto¬ßung zu einer Zunahme des NOM-Rückhalts von 27 % (± 2 %) bei 0 V auf 72 % (± 5 %) bei -2,5 V. Im dritten Teil dieser Arbeit wurden Versuche zur elektrosorptiven UF im Deadend-Betrieb durchgeführt. Durch das Anlegen eines positiven Potentials (+2,5 V) an die M5-Membran können NOM-Rückhalte wie im Bereich von Nanofiltrationsmembranen er¬reicht werden. Durch Umpolen des Potentials (von positiven zu negativen Werten), werden die zuvor elektrosorbierten NOM wieder von der Membran desorbiert. Die Trennleistung der UP150 wird durch Elektrorepulsion von 150 kDa (0 V) auf ca. 5 kDa ( 2,5 V) und die Trennleistung der M5 wird durch Elektrosorption von 1000 kDa (0 V) auf 0,7 kDa (+2,5V) gesteigert. Demnach können sowohl mit der elektrorepulsiven wie auch mit der elektrosorptiven UF der Permeability-Selectivity-Trade-off überwunden werden, wobei sich die elektrosorptive UF (hinsichtlich Permeabilität und Rückhalt) als vorteilhafter herausstellt. | [

This exploratory study examines the transition from school to post-school adulthood of young people with mental disability, asking for the conducive or prejudicial factors at school as well as at home. Thus, 40 students of professional practice level in three special schools for mentally disabled, as well as their parents and teachers were interviewed in a panel design, semi-standardized qualitative approach. The study shows that young adults with mental disability want to be recognized as a full member of society. Also, they want to be actively involved according to their resources. While students’ parents support them fully, teachers do not tap the full potential of the young, for instance by person centered future planning. The study concludes with indications for a reform of the professional practice level. <engl.> Der sonderpädagogische Diskurs fordert als Leitbilder für den Umgang mit Menschen mit Behinderung Inklusion, Selbstbestimmung und soziale Teilhabe.

3A1735447951.jsonld | Tailoring the interface of magnetic Nano-Composites | The work presented here aims for the artificial variation of magnetic nanoparticle surfaces using different macromolecular building blocks and grafting methods which incorporated straightforward grafting approaches of various commonly used polymers and furthermore the introduction of novel functional (weak) polyzwitterions as surface ligands. The latter polymers gave access to multifunctional nanocarriers that react both to external magnetic fields and the surrounding pH value. The majority of the polyzwitterions currently investigated consists of functional groups that enable permanent zwitterionic state over a very wide pH range. The novelty of the polymers presented in this work lies in the pHdependent charge through the use of weak acid and base groups. These weak polyzwitterions expand the latest scope of polymer coatings for magnetic nanoparticles and enable ways of charge-based transport or catch and release at the nanoscale. The synergistic effects by combination of magnetic core and pH responsive shell enable possible applications in various fields, ranging from recyclable wastewater treatment agents to tailored drug delivery nanocarriers, as outlined in this work. The investigation of interfacial electrostatic interactions with charged guests was of great interest according to the application areas. A fundamental understanding of the underlying mechanisms could be obtained by varying both the surrounding pH, guest molecules and polyzwitterion on the surface of the MCNPs. Three different coatings based on polyampholytes enabled hereby changes in the electrostatic interactions and gave insights into the underlying and as yet hardly investigated dependency of functional groups and electrostatic interactions on surfaces. The electrostatic interactions have furthermore been studied intensively to provide a straightforward approach to the synthesis of magnetic nanoparticles with versatile new properties such as fluorescence and plasmonic resonance based on interface adsorption, which allowed the merging of different properties by a noncovalent combination of individual building blocks resulting in new types of nanocomposites. | [

3A862799864.jsonld | Lernförderung im Mathematikunterricht durch Advance Organizer : eine quantitativ-empirische Erhebung zur Untersuchung der Wirksamkeit eines Advance Organizer für heterogene Lerngruppen im Mathematikunterricht der 3. Jahrgangsstufe | Advance organizer can contribute to activate prior knowledge, for example by providing the students with an organizational help that can be used for new learning contents in a teacher-centered phase at the beginning of the lesson. Findings from meta-analyses confirm the overall effectiveness of this method. The research objective of this project is the evaluation of advance organizers in heterogeneous groups in mathematics. Following an empirical quantitative approach in a randomized control group design with pretest, intervention, post-test, and two follow-up assessments, this method is evaluated in terms of its effectiveness. Positive effects of the advance organizer are particularly achieved in remembering specific content by the entire group. Higher effects regarding remembering specific and general mathematics performance can be identified for students at risk. Regardless of the use of the advance organizer, prior knowledge and learning behavior particularly affect the learning and retention of knowledge. <engl.> Zur Aktivierung des Vorwissens kann ein Advance Organizer eingesetzt werden, mit zu Beginn des Unterrichts in einer lehrerzentrierten Präsentation eine Organisationshilfe für neue Lerninhalte zur Verfügung gestellt wird.

3A736167137.jsonld | Chaotic diffusion in nonlinear Hamiltonian systems | This work investigates diffusion in nonlinear Hamiltonian systems. The diffusion, more precisely subdiffusion, in such systems is induced by the intrinsic chaotic behavior of trajectories and thus is called chaotic diffusion''. Its properties are studied on the example of one- or two-dimensional lattices of harmonic or nonlinear oscillators with nearest neighbor couplings. The fundamental observation is the spreading of energy for localized initial conditions. Methods of quantifying this spreading behavior are presented, including a new quantity called excitation time. This new quantity allows for a more precise analysis of the spreading than traditional methods. Furthermore, the nonlinear diffusion equation is introduced as a phenomenologic description of the spreading process and a number of predictions on the density dependence of the spreading are drawn from this equation. Two mathematical techniques for analyzing nonlinear Hamiltonian systems are introduced. The first one is based on a scaling analysis of the Hamiltonian equation… | [

3A1824140142.jsonld | Vegetation dynamics in northern south America on different time scales | The overarching goal of this doctoral thesis was to understand the dynamics of vegetation activity occurring across time scales globally and in a regional context. To achieve this, I took advantage of open data sets, novel mathematical approaches for time series analyses, and state-of-the-art technology to effectively manipulate and analyze time series data. Specifically, I disentangled the longest records of vegetation greenness (>30 years) in tandem with climate variables at 0.05° for a global scale analysis (Chapter 3). Later, I focused my analysis on a particular region, northern South America (NSA), to evaluate vegetation activity at seasonal (Chapter 4) and interannual scales (Chapter 5) using moderate spatial resolution (0.0083°). Two main approaches were used in this research; time series decomposition through the Fast Fourier Transformation (FFT), and dimensionality reduction analysis through Principal Component Analysis (PCA). Overall, assessing vegetation-climate dynamics at different temporal scales facilitates the observation and understanding of processes that are often obscured by one or few dominant processes. On the one hand, the global analysis showed the dominant seasonality of vegetation and temperature in northern latitudes in comparison with the heterogeneous patterns of the tropics, and the remarkable longer-term oscillations in the southern hemisphere. On the other hand, the regional analysis showed the complex and diverse land-atmosphere interactions in NSA when assessing seasonality and interannual variability of vegetation activity associated with ENSO. In conclusion, disentangling these processes and assessing them separately allows one to formulate new hypotheses of mechanisms in ecosystem functioning, reveal hidden patterns of climate-vegetation interactions, and inform about vegetation dynamics relevant for ecosystem conservation and management. | [

3A668019573.jsonld | How Islamic parties organize at the local level in post-Suharto Indonesia : an empirical study of six major Islamic parties In The Tasikmalaya District, West Java Province | Many studies have explored the phenomena of Islamic parties in Indonesia, the largest predominantly Muslim country in the world. However, little effort has been made to explore the organizational structures of Islamic parties in post-Suharto Indonesia. The existing studies have also paid little attention to the role of Islamic parties at the regional level in the implementation of the decentralized system in terms of the relationship between the central and regional governments. This study is an attempt to provide a more comprehensive analysis of the way the Islamic parties at the regional level in post-Suharto Indonesia organize. In doing so, the organization of the Islamic parties is examined in three different dimensions, i.e., the party organization on the ground (political linkage between the Islamic parties and their members or supporters), the party organization in central office (leadership of the Islamic parties), and the party organization in public office (the role of the Islamic parties in policy-making). As the units of analysis, this study selects six major Islamic parties, i.e., the National Mandate Party (Partai Amanat Nasional or PAN), National Awakening Party (Partai Kebangkitan Bangsa or PKB), Reform Star Party (Partai Bintang Reformasi or PBR), United Development Party (Partai Persatuan Pembangunan or PPP), Justice and Prosperity Party (Partai Keadilan Sejahtera or PKS) and Star and Crescent Party (Partai Bulan Bintang or PBB). Despite the fact that these parties experienced a significant decrease at the national level, most of them succeeded in maintaining or increasing their level of political support at the regional level. Meanwhile, this study focuses on the Tasikmalaya district as the locus of study because it has become one of the regional bases for these parties to maintain or increase their political achievement. The district also has a long historical root in the Islamic state movement in Indonesia. As a result, Muslims in the district have a strong Islamic sentiment. This study proposes two major findings. Firstly, the way the Islamic political actors organize the Islamic parties in Tasikmalaya district suggests that these parties contain some elements of the elite-based party, mass-based party, electoralist party, and cartel party models. In other words, the Islamic parties in post-Suharto Indonesia have hybrid features. Therefore, the organizational features of the Islamic parties in post-Suharto Indonesia are not completely exceptional or unique compared to the organizational features of party politics in other developing countries. Moreover, the organizational development of the contemporary Islamic parties in Indonesia takes different trajectories. In the case of the PAN and PPP, these parties are in a transitional stage from the mass-based party model to the electoralist party model. The organizational development of the PKS suggests that this party is experiencing a maturation process of the mass-based party model, while the organizational development of the PKB, PBR and PBB shows that these parties are experiencing a stagnation process in the stage of the elite-based party. Secondly, the case of the Tasikmalaya district also indicates that the Islamic political actors in Indonesia rely on rational calculations rather than ideological considerations when they manage their Islamic parties. In this sense, the PBB, PKS, PPP and PBR as the Indonesian Islamist parties have experienced a moderation process. The way these parties organize has not led to the Islamisation of the state, but it has led to the long term Islamisation of society. Das Phänomen islamischer Parteien in Indonesien, dem größten vorwiegend muslimischen Land der Welt wurde bereits vielfach untersucht. Bisherige Studien haben allerdings bisher zu wenig Augenmerk auf die Organisationsstrukturen dieser Parteien in der Post-Suhartoära gerichtet. Ebenso versäumten es bisherige Studien, die Rolle islamischer Parteien auf der regionalen Ebene für die Zentrums-Peripheriebeziehungen unter den Bedingungen der Dezentralisierung zu untersuchen. Diese Studie analysiert die Organisation islamischer Parteien auf der regionalen Ebene im Indonesien der Post-Suhartoära entlang der Dimensionen Parteiorganisation vor Ort (politische Bindungen zwischen den islamischen Parteien und ihren Mitgliedern oder ihrer Anhängerschaft), Parteiorganisation in der Parteizentrale (Führung der islamischen Parteien) und Parteiorganisation in öffentlichen Ämtern (die Rolle der islamischen Parteien bei der Politikgestaltung). Untersuchungsgegenstand dieser Studie sind sechs bedeutende islamische Parteien: die Partei des Nationalen Mandats (Partai Amanat Nasional oder PAN), die Partei des Volkserwachens (Partai Kebangkitan Bangsa oder PKB), die Stern Reform Partei (Partai Bintang Reformasi oder PBR), die Vereinigte Entwicklungspartei (Partai Persatuan Pembangunan oder PPP), die Partei für Wohlstand und Gerechtigkeit (Partai Keadilan Sejahtera oder PKS) und die Partei Halbmond und Stern (Partai Bulan Bintang oder PBB). Trotz eines deutlichen Rückgangs an politischer Unterstützung auf der nationalen Ebene konnten diese Parteien ihren Stimmenanteil auf der regionalen Ebene beibehalten oder sogar vergrößern. Räumlich konzentriert sich diese Studie auf den Bezirk Tasikmalaya (Provinz West Java), der eine besondere Hochburg islamischer Parteien darstellt. Zusätzlich ist auch die Bewegung zur Islamisierung des Staates in diesem Bezirk tief verwurzelt, so dass davon ausgegangen werden kann, dass die Muslime des Bezirks über eine besonders streng islamische Gesinnung verfügen. Die Studie gelangt zu zwei Hauptergebnissen. Erstens kombiniert die Organisation islamischer Parteien im Bezirk Tasikmalaya Elemente von Eliten-, Massen-, elektoralen und Kartellparteimodellen. Islamische Parteien in Post-Suharto Indonesien besitzen damit hybride Eigenschaften. Die Organisation islamischer Parteien in Post-Suharto Indonesien ist folglich weder außergewöhnlich noch einzigartig im Vergleich zu Parteien in anderen Entwicklungsländern. Ferner entwickeln sich moderne islamische Parteien in Indonesien in unterschiedliche Richtungen. So befinden sich PAN und PPP in einer Übergangsphase von der Massen- zur elektoralen Partei. Die organisatorische Entwicklung der PKS deutet auf eine Konsolidierung des Modells der Massenpartei hin, während die organisatorische Entwicklung der PKB, PBR und PBB im Elitenstadium stagniert. Zweitens zeigt der Fall des Bezirks Tasikmalaya, dass auch islamisch gesinnte politische Akteure in Indonesien auf rationale Kalkulationen statt ideologischer Erwägungen bei der Verwaltung ihrer Parteien setzen. So zeigt diese Studie etwa, dass PBB, PKS, PPP und PBR einen Mäßigungsprozess durchlebt haben. In diesem Sinne hat die Organisationsform islamischer Parteien in Indonesien nicht zur Islamisierung des Staates geführt, wohl aber zur langfristigen Islamisierung der Gesellschaft beigetragen. | [

3A1809924626.jsonld | The Walking Dead at Saqqara : strategies of social and religious interaction in practice | Funerary rituals and the cult of the dead are classics of research in religious studies, especially for ancient Egypt. Still, we know relatively little about how people interacted in daily life at the city of Memphis and its Saqqara necropolis in the late second millennium BCE. By focussing on lived ancient religion, we can see that the social and religious strategies employed by the individuals at Saqqara are not just means on the way to religious, post-mortem salvation, nor is their self-representation simply intended to manifest social status. On the contrary, the religious practices at Saqqara show in their complex spatiality a wide spectrum of options to configure sociality before and after one's own death. The analytical distinction between religion and other forms of human practices and sociality illuminates the range of cultural practices and how people selected, modified, or even avoided certain religious practices. As a result, pre-funerary, funerary and practices of the subsequent mortuary cults, in close connection with religious practices directed towards other ancestors and deities, allow the formation of imagined and functioning reminiscence clusters as central social groups at Saqqara, creating a heuristic model applicable also to other contexts | [

Vielmehr übernimmt sie die sortalen Besonderheiten der jeweiligen Verblesart; die Weglassung wäre somit sortal‐semantisch neutral.Umfangreiche Einzelverbuntersuchungen werden zeigen, dass einzig die Festlegung auf kontextuell gegebene Argumente bei definiter Weglassung als Effekt von lexikalisch bedingter Weglassung analysiert werden kann.

3A785279199.jsonld | Regulatory elements in the terpenoid biosynthesis of defensive secretions in leaf beetle larvae | Chrysomelina larvae possess a sophisticated strategy in terms of chemical defense eminently adapted to their natural habitat. In case of predatory attack, the deterrent secretions are released from dorsal thoracic and abdominal glands. The source of the deterrent compound for this ingenious mechanism depends on different biosynthetic strategies and subdivides the Chrysomelina in three different groups. The ancestral strategy represents the de-novo production of iridoids. Species belonging to this group e.g. Phaedon cochleariae and Gastrophysa viridula produce the deterrent compound independently of host plant derived precursors. More evolved species of the Chrysomela as well as Phratora vitellinae use the approach of sequestering phenol glucosides to produce salicylaldehyde. Based on the precursor salicin, this defense strategy is highly adapted to the secondary metabolites of the salicaceous plant which restricts the larvae in their forage. The third group is represented by several species of the interrupta-group belonging to the genus Chrysomela. They exhibit a combined biosynthetic strategy by using de-novo produced and phytogenic derived precursors to generate butyrate-esters as defensive compounds. Irrespective of different deterrent substances, the defensive systems of all groups exhibit per se a uniform architecture and morphology. Together with the self-contained biosynthesis of these compounds, the Chrysomelina larvae represent an excellent system to analyze regulatory processes as well as uncover evolutionary relationships regarding the defensive system. In the present thesis, I identified and characterized enzymes essentially involved in the de-novo biosynthesis of the defensive compound Chrysomelidial of P. cochleariae. | [

They are increasingly moving in a technologically advanced environment and information and communication technologies are influencing their profession. Advantages of the technologies can conflict with the data privacy rights of patients who have an interest in the self-determined data transfer. This tense situation and the previously neglected topic of health data protection are gaining in importance, as a result of the recent European legal development. The area is also characterized by specific regulations for the electronic health card and is regulated by the need for medical confidentiality. This results in a highly complex system of standards, which so far has not been systematically recorded. The author is concerned with the regulatory framework for health related technology and systems (e-health), including the legal aspects of national and European law. Ärzte sind seit jeher auf Informationen ihrer Patienten angewiesen, um eine hochwertige medizinische Versorgung zu gewährleisten. Sie bewegen sich zunehmend im technikgeprägten Umfeld und Informations- und Kommunikationstechnologien beeinflussen ihren Beruf. Vorteile der Technologien können mit Persönlichkeitsrechten von Patienten kollidieren, die ein Interesse am selbstbestimmten Datenumgang haben. Diese Spannungslage und das bisher tendenziell vernachlässigte Thema des Gesundheitsdatenschutzes erlangen – beflügelt durch die jüngere europäische Rechtsentwicklung – immer größere Bedeutung. Das Gebiet ist zudem durch spezifische Regelungen für die elektronische Gesundheitskarte geprägt und wird flankiert von der ärztlichen Schweigepflicht. Daraus resultiert ein hochkomplexes Normengeflecht, das bislang systematisch kaum erfasst wurde.

Perturbation methods are used to determine the leading-order effects of friction and drag uncertainty in tidal stream power assessment. The methods for uncertainty transfer presented in this thesis could readily be applied to numerous other problems encountered in hydraulic engineering, such as flow routing, urban flood risk, and reservoir sedimentation.

3A1820607569.jsonld | Violence and educational quality : effects of violence on the learning outcomes of students in Cameroon | This study examines violence and its relation to learning outcomes of secondary school students in Cameroon. The study interconnected with educational quality values of accessibility, inclusiveness, favorable learning climate, tolerance, and responsible behavior. The government of Cameroon has attempted to uphold these values through legislation. In spite of this position, violence at school is still observable on a daily basis, not respecting the human rights of children and young learners and hindering them from learning. The study was to understand the effects of violence on their motivation and self-esteem, and its influence on their learning outcomes and the research question focused on the extent of violence in education. A model was operationalized measuring physical violence, psychological violence, structural violence and sexual violence at school and at home, mediated by self-esteem, motivation and health to the learning outcome, quantified by class repetition, grades and reading enjoyment. The study was designed using a quantitative approach with cross-sectional survey for students. Questionnaires were designed from approved scales which had been adopted to the Cameroonian background by two pretests. Data had been collected from a sample population of 924 students in grades four to seven in Cameroon. The data collection was approved by the regional authorities. The collected data was transformed by controlling the social background and reflecting different types of experiences of violence. The collected information was analyzed using descriptive statistics (means, standards deviation), and inferential statistics (ANOVA). The results indicate an acute prevalence of school violence. Students in Cameroon are affected by four ways of violence. About 20 % of students feel physical violence and psychological violence. More than half of the students’ experiences structural violence and about 23 % have experiences of sexual violence. As a zero-policy on experienced violence is the wished standard, the huge ratio of violence in the life of students in Cameroon becomes visible. The study shows that these experiences of violence affect the self-esteem and the motivation to learn. However, a significant relation between different forms of violence and school grades was not found in this study. In addition, the study shows the poor school quality, and a very discouraging socioeconomic background of students. In the perspective paradigm, the schools are neither an environment of the protection of students nor open spaces for real-world transmission of values. Violence remains a challenge. This requires coordinated and focused action. The study develops a number of suggestions for school practice to overcome this situation and suggests follow-up studies. | [

Im Gegen-satz zu den in der Literatur beschriebenen Entwicklungen müssen sich diese neuen Zentren jedoch nicht zwangsläufig komplementär zu bereits etablierten Standorten verhalten, sondern können durchaus mit diesen konkurrieren. Langfristig kann dies großmaßstäbige Verlagerun-gen von Produktionsschwerpunkten auf globaler Ebene zur Folge haben. This study rests on three regional case studies. Using the example of the West-Indian Palan-puri community which has specialised in trading diamonds, it shows that transnational entre-preneurs can significantly contribute to transferring knowledge over great distances and thus be considered as an important element of knowledge-based regional development. Global pipelines developed by transnational entrepreneurs can support the outflow of knowledge about markets and technologies from an existing cluster. When applied to a different regional context, this knowledge may prove supportive to the formation of new clusters. These devel-opments need not necessarily result in locations that complement each other, as suggested in the literature. Rather, the new centres can enter into competition with the established ones. In the long-run, this can result in numerous relocations on a global scale.

3A1652025189.jsonld | The Black Hole-Neutron Star Binary Merger in Full General Relativity : Dependence on Neutron Star Equations of State | This thesis presents a systematic study of the orbital evolution, gravitational wave radiation, and merger remnant of the black hole-neutron star binary merger in full general relativity for the first time. Numerical-relativity simulations are performed using an adaptive mesh refinement code, SimulAtor for Compact objects in Relativistic Astrophysics (SACRA), which adopts a wide variety of zero-temperature equations of state for the neutron star matter. Gravitational waves provide us with quantitative information on the neutron star compactness and equation of state via the cutoff frequency in the spectra, if tidal disruption of the neutron star occurs before the binary merges. The cutoff frequency will be observed by next-generation laser interferometric ground-based gravitational wave detectors, such as Advanced LIGO, Advanced VIRGO, and KAGRA. The author has also determined that the mass of remnant disks are sufficient for the remnant black hole accretion disk to become a progenitor of short-hard gamma ray bursts accompanied by tidal disruptions and suggests that overspinning black holes may not be formed after the merger of even an extremely spinning black hole and an irrotational neutron star | [

3A1746341653.jsonld | Motor-cognitive dual task performance : a neuro-cognitive approach investigating age-related differences based on the "Theory of Visual Attention" | Although an inherent part of everyday life, motor-cognitive dual-tasking - the ability to perform a cognitive and motor task simultaneously - still has many open questions. The mechanisms underlying these abilities are not well understood, and terms such as “attention” often make no clear distinction between various attentional sub-processes. This is especially true of the age-related decline in dual-tasking abilities, in which the visual task demands have been shown to become increasingly exigent. Two studies are presented in this dissertation. Study 1 introduced a novel paradigm to objectively measure motor-cognitive dual-task performance, whilst Study 2 used this new paradigm to investigate the impact of the aging process and of the cognitive load of a task on dual-tasking abilities. These studies combined a simple, continuous, and repetitive motor task with a whole report task based on the Theory of Visual Attention (TVA). This measures different parametric estimates of attentional performance, and shows how these were affected by a concurrent motor task. Each task was carried out separately as a single task, as well as simultaneously in a dual-task condition. Study 1 demonstrated that the visual processing rate and visual short-term memory (VSTM) storage capacity showed a dual-task-related decline in middle-aged adults. Study 2 indicated that older adults performing a simple motor task showed similar declines in performance as younger adults who carried out a more complex motor task. Taken together, the studies show that even a relatively simple motor task utilises a central attentional capacity, suggesting that motor-cognitive dual-tasking is conducted in a capacity sharing manner. Furthermore, the VSTM appears to be the constraining mechanism which underlies dual-tasking ability, and it is this central capacity which is negatively impacted in a qualitatively similar manner by both increased age in older adults, as well as by the task load in younger adults. | [

3A737129026.jsonld | Insights into brain networks from functional MRI and graph analysis during and following attentional demand | The human brain is a highly flexible and adaptive information processing system that allows us to interact with our environment and to adjust behaviour to current task demands. However, if a task demand is high, the flexibility and capability of the brain to adapt is challenged. The studies of the current thesis aimed to shed light on neural mechanisms that are involved in adaptive processes of the brain in order to match the demands in an attentional task and on changes in the whole brain network configuration that reflect consequences of task performance. Data basis were functional MRI data which were analyzed with a BOLD approach and graph analysis. Brain networks that mediate ‘attentional effort’ were identified as being involved during the task. These networks were further functionally differentiated in motivational and arousal components. Further, the task performance has led to long-termed changes in the brain topology, as reflected in lowered functional network integration and increased clustering. These changes persisted for 12 minutes following the task and began only slowly to recover. <engl.> Das menschliche Gehirn ist ein sehr flexibles und adaptives Informationsverarbeitungssystem, das uns ermöglicht, mit unserer Umwelt zu interagieren und unser Verhalten auf Anforderungen anzupassen. Wenn eine Anforderung jedoch hoch ist, wird diese Flexibilität und Anpassungsfähigkeit herausgefordert.

Die Datenbasis waren funktionelle MRT Daten, die sowohl mit einem BOLD-Ansatz als auch mit Graphentheorie analysiert wurden. Es wurden Gehirnnetzwerke, die „Attentional Effort“ während der Aufgabe steuern, identifiziert, die zudem in funktionelle Komponenten von „Motivation“ und „Arousal“ unterteilt werden konnten. Des Weiteren hat die Aufgabe zu langen Veränderungen in der Gehirntopologie geführt, die sich mit reduzierter Netzwerkintegration und erhöhtem Clustering zeigten.

3A874139767.jsonld | Interpolation modulo theories | Zusammenfassung: We present new concepts and techniques to generate interpolants from the proofs produced by SMT solvers. The overall result is to expand the scope of interpolation to the wealth of theories that are supported by SMT solvers. SMT solvers can prove satisfiability for an ever growing number of theories (and for their combinations; theories are often combined to account for rich data as commonly used in complex systems). However, according to the present state of the art, SMT solvers can compute interpolants only for a few selected theories (and it is unknown how two existing methods can be combined to compute interpolants in the combination of the theories). The notion of \emph{interpolant} goes back to Craig's interpolation theorem for first-order logic. An increasing range of software analysis tools use techniques based on interpolants.We present a new algorithm to compute Craig interpolants from the proof produced by an SMT solver, for a wide range of theories and for their combination. The algorithm uses the proof produced by the SMT solver but it does not interfere with the intermediate steps of producing the proof and it does not manipulate the proof. As a consequence, the algorithm is generic in the theory and it can be put on top of an existing SMT solver without impeding its generality and without impeding its efficiency.We also present an extension of the algorithm to tree interpolants. Tree interpolants are used whenever the behaviour of a software is not represented as a linear sequence (for example, to account for the return of a function call in the execution of a program). To our knowledge, this is the first algorithm that computes (provably correct) tree interpolants from SMT proofs. Motivated by the fact that interpolation algorithms without an existing correctness proof are notoriously wrong, we present a proof for the correctness of the tree interpolation algorithm.We show how one can instantiate the algorithm for the quantifier-free fragment of the theory of uninterpreted functions and the theory of linear arithmetic over the integers or the reals, and we have implemented the resulting algorithm. The implementation is part of the interpolating SMT solver SMTInterpol. It is freely available under LGPL. Feedback from users is encouraging | [

3A1877653675.jsonld | Business development and brand management : a reciprocal relationship | Business development and brand management are core functions of a business that fuel corporate growth and drive value for consumers, for companies, and for society. Integrating the two business areas promises synergistic added value that goes beyond their individual impact spectrums. While academic research has collectively advanced our understanding of brand management, research in business development is relatively underrepresented. As a management concept that is of great importance in the corporate world today, the relevance of business development cannot be denied in academia. Moreover, the interrelationship between business development and brand management has been widely neglected. Both business fields benefit from each other, suggesting an exigency for a deeper integration between the two. Towards that goal, this dissertation presents a comprehensive overview of the reciprocal relationship of business development and brand management that further stretches the academic knowledge space. Throughout the doctoral thesis, the author structures this interrelationship, enhances theory for both business areas and their integration, suggests managerial implications and identifies future research directions that require scholarly attention. The doctoral thesis aims to align business development and brand management theory and practice with the realities of the business world. In three research papers, this thesis develops an analysis of the reciprocal relationship of business development and brand management. For this purpose, a variety of methods ranging from a systematic literature review and qualitative work to empirical research employing structural equation modeling and experimental studies are applied. Theoretically, business development, innovation management, brand management and sustainability inform the frame of this work. Finally, this research project aims at contributing to (sustainable) business and brand growth. | [

3A1729164765.jsonld | Influence of nutrient availability on soil respiration and microbial activity in a tree-grass ecosystem | Increased availability of nitrogen (N) and phosphorus (P) due to human activity has potential to increase carbon (C) stocks if it leads to added plant productivity. Whether increased productivity leads to changes in ecosystem C stocks is dependent on if processing of C by soil microbes is also increased by nutrient addition or its stoichiometry. Likely, the response of soil C cycling to changes in N:P depends on site fertility. In tree-grass ecosystems, like oak-savannas, there is variation in soil organic C (SOC) due to in situ decomposition of tree litter. The aim of this work is to quantify how N:P availability affects C cycling in oak-savanna soil habitats. We found that soil respiration and its response to nutrient addition differed between habitats. Open grassland had higher respiration with N addition while soil under canopies had the opposite, confirming that SOC content modifies soil respiration response to nutrient addition. A second approach examined ecosystem allocation of added N using a stable isotope tracer. Open grassland with high N:P had the most label recovery; meaning that it is more N-limited than under canopy. A final tract looked at changes in microbial activity after N and P addition where carbon-use efficiency (CUE) was measured on soils with short or long-term fertilization history. Treatments had no effect on CUE under canopies. Grassland had lower CUE when single nutrients were added in the short-term, but unchanged when combined. Thus, stoichiometric imbalance reduces CUE in the short term, but more study is needed. Overall, oak-savanna microbial activity is not nutrient-limited, but limited by C availability. Grassland soil of oak-savannas is more sensitive to changes in nutrient availability than that under canopies. Grassland soil C is more susceptible to loss when N:P stoichiometry is higher due to increased respiration. Greater mechanistic understanding is needed of how N and P alter microbial activity. | [

3A1852845511.jsonld | Banana production in Venezuela : novel solutions to productivity and plant health | This book presents an important contribution to the knowledge of the banana soils of Venezuela. Banana, the edible fruit of Musaceae, is a staple food for more than 400 million people worldwide due to their nutritional and energy attributes. This makes Musaceae a crop of worldwide relevance, particularly in tropical regions, highlighting the impact of improved Musaceae cropping systems in the current efforts worldwide oriented towards a new agricultural revolution based on sustainable intensification. To achieve this, better practices for food production based on scientific and technical research capable to consider the complexity and variability within the agri-food sector are necessary. The research presented in this book is oriented towards providing answers to the causes of two aspects considered of high relevance for banana production, both affecting productivity and sustainability, always addressed for the Venezuelan conditions, one of the world's largest producing countries: 1- The impact of phytosanitary risks related to Fusarium Wilt (FW) and the influence of the soil on the incidence of Banana Wilt (BW); and 2- An observed trend towards loss of productivity and decline of soil quality in some commercial farms of Aragua and Trujillo states in Venezuela. The book presents a pioneering study in the application of categorical regression (CATREG) in the characterization of banana soils and analyses soil morphological variables, such as texture, dry consistency, biological activity, reaction to HCl, and type of structure to characterize soil productivity for growing healthy bananas. It develops, for the first time in Venezuela, risk analysis and climatic suitability maps for lethal wilt disease in bananas caused by Fusarium oxysporum f. sp. cubense (Foc) Tropical Race 4 (TR4) (syn. Fusarium odoratissimum). Innovative machine learning techniques are used to predict BW so that future crop development can be done more efficiently and sustainably | [

Hence, it is important that people detect and correct their errors early on in such judgments, which was the overarching goal of this dissertation. A series of eight studies provided robust evidence that people are able to detect the direction of their own errors (whether they guessed too high or too low), but that they have difficulties correcting them in a second step with the help of interventions. Moreover, an adjusted version of this intervention failed to enable people to make better use of advice that could point either in the right or wrong direction. First positive evidence was found for an intervention variant in an individual judgment context with historic estimation tasks (“In which year was…?”). In these tasks, subjects were able to improve their judgments when they were explicitly instructed to make only small corrections of their judgments. Last, a meta-analysis across all studies showed robust evidence for a hierarchical sampling-model that explains under which circumstances people can detect the direction of their errors and under which they cannot. Quantitative Urteile, wie Prognose- oder Schätzaufgaben, liegen vielen wichtigen Entscheidungen zugrunde. Deshalb ist es wichtig, dass Menschen bei solchen Urteilen ihre Fehler frühzeitig erkennen und korrigieren, was das übergeordnete Ziel dieser Dissertation war. In einer Serie von insgesamt acht Studien zeigte sich robuste Evidenz dafür, dass Menschen in der Lage sind, die Richtung ihrer eigenen Fehler zu erkennen (ob sie zu hoch oder zu niedrig geschätzt haben), aber Schwierigkeiten haben, diese im Anschluss mit der Hilfe von Interventionen zu korrigieren.

3A1699196230.jsonld | Deal selection and investor value-added in entrepreneurial equity financing : new evidence from venture capital and crowdfunding | This book presents empirical analyses which investigate entrepreneurial equity investors’ investment choices and value-added to portfolio companies. The results suggest that equity-crowdfunded companies’ subsequent performance is causally negatively affected compared to peers that use traditional entrepreneurial equity financing, since equity crowdfunders add less value to portfolio companies than venture capitalists and business angels. Additional analyses suggest that venture capital investors’ specialisation in certain branches of industry has opposite effects on their ability to select companies with high potential and add value to them. High levels of industry specialisation positively affect venture capitalists’ ability to select companies with high potential but are detrimental to investors’ value-added. These effects also have demonstrable implications for the formation and composition of investment syndicates. Dieses Buch präsentiert empirische Analysen zur Investitionsauswahl und Wertstiftung von Risikokapitalgebern. Die Ergebnisse zeigen, dass Unternehmen, die eine Equity-Crowdfunding-Finanzierung nutzen, in der Folge geringeren unternehmerischen Erfolg erzielen als vergleichbare Unternehmen, die auf eine traditionelle Risikokapital-Finanzierung zurückgreifen. Die Ergebnisse legen nahe, dass dieser negative Effekt durch die vergleichsweise geringere Wertstiftung von Equity-Crowdfunding-Investoren verursacht wird. Weitere Analysen zeigen, dass die Branchenspezialisierung von Venture-Capital-Investoren gegenläufige Effekte auf deren Fähigkeit zur Investitionsauswahl und Wertstiftung hat. Es zeigt sich, dass größere Branchenspezialisierung Investoren besser befähigt, potenzialstarke Unternehmen in der jeweiligen Branche auszuwählen, aber ihrer Wertstiftung abträglich ist. Diese Effekte haben auch nachweisebare Implikationen auf die Bildung und Zusammensetzung von Investitionssyndikaten. | [

3A565556614.jsonld | On the influence of local inhomogeneities on cosmological observables : from galaxies to the microwave background | Despite the good consistency of the cosmological standard model with the bulk of present observations, a number of unanticipated features have recently been detected within large-angle data of the Cosmic Microwave Background. Among these features are the anomalous alignments of the quadrupole and octopole with each other, their unexpected alignments with certain astrophysical directions (e.g. equinox, ecliptic) as well as the stubborn lack of angular autocorrelation on scales > 60ʿ. We pursue the idea that processes of non-linear structure formation could contribute to the large-scale anomalies via a local Rees-Sciama effect. We find that existing structures are able to produce CMB contributions up to 10^-5. For an axially symmetric setup we show that this effect does induce alignments, albeit not of the same form as extracted from the data, and that yet a Solar system effect seems preferred by the data. Moreover, we address the relationship between the intrinsic alignment of quadrupole and octopole on the one hand and the anomalous angular two-point correlation function on the other hand. We demonstrate the absence of any correlations between them and are able to exclude the joint case at high confidence with respect to recent data. This result enables us to put stringent constraints on any relevant model that exhibits an explicit axial symmetry. | [

3A1794884521.jsonld | Der Herrscher im Bild : Präsenz und Propaganda in Büchern des Quattrocento | Today, images have become indispensable in the political sphere. They are often used to generate and consolidate power. The "language" of images communicates more directly than a text and appeals more to the emotions, which is why they are used for persuasion or propaganda purposes. Images can establish presence, illustrate complicated issues and make things evident. This practice was recognised and implemented consistently for the first time since antiquity in the early Italian Renaissance. The book was at the centre of the text-pictorial staging strategies of Italian rulers. From the 1440s onwards, there was an increasing interest in humanist books at the courts, which artfully portrayed the vita of a contemporary ruler in the form of epic poems, virtue writings or historiography. These texts, written by court humanists, were often accompanied by images that competed fruitfully with words, visually interpreting and interpreting the texts - rather than merely illustrating them - through their fictional possibilities of presence and evocation of antiquity. The points of reference treated in detail are court artists such as Pisanello, Mantegna, Piero della Francesca and the "classics" of antiquity. Like the medals related to them, books with contemporary historical images were sent as diplomatic gifts to friendly courts and presented in courtly ceremonial. Whether the Visconti and Sforza of Milan, the Este of Ferrara, the Malatesta of Rimini, Federico da Montefeltro of Urbino or the kings of Aragon of Naples, they all recognised the power of mobile word-image combinations to secure memoria and fama. Bilder sind heute im Raum des Politischen unerlässlich geworden. Vielfach werden sie genutzt, um Macht zu generieren und zu festigen. Die „Sprache“ der Bilder teilt sich unmittelbarer mit als ein Text und appelliert stärker an das Gefühl, weshalb sie zu Überredungs- oder Propagandazwecken eingesetzt werden. Bilder können Präsenz herstellen, komplizierte Sachverhalte veranschaulichen und Dinge evident machen. Diese Praxis wurde zum ersten Mal seit der Antike konsequent in der italienischen Frührenaissance erkannt und umgesetzt. Im Zentrum text-bildlicher Inszenierungsstrategien italienischer Herrscher stand dabei das Buch. Seit den 1440er Jahren ist an den Höfen ein zunehmendes Interesse an humanistischen Büchern zu verzeichnen, die im Epos, in Tugendschriften oder in einer Historiografie die Vita eines zeitgenössischen Regenten kunstvoll darstellen. Diese von Hofhumanisten verfassten Texte wurden häufig von Bildern begleitet, die in einem fruchtbaren Konkurrenzverhältnis zum Wort stehen und die Texte – anstatt sie lediglich zu illustrieren – über ihre fiktionalen Möglichkeiten der Präsenz und der Evokation von Antike visuell ausdeuten und interpretieren. Ausführlich behandelte Referenzpunkte sind dabei Hofkünstler wie Pisanello, Mantegna, Piero della Francesca und die „Klassiker“ der Antike. Wie die mit ihnen verwandten Medaillen wurden Bücher mit zeithistorischen Bildern als diplomatische Geschenke an befreundete Höfe verschickt und im höfischen Zeremoniell präsentiert. Egal ob die Visconti und Sforza in Mailand, die Este aus Ferrara, die Malatesta von Rimini, Federico da Montefeltro in Urbino oder die Könige von Aragon aus Neapel: Sie alle erkannten die Macht von mobilen Wort-Bild-Kombinationen, um „memoria“ und „fama“ zu sichern. | [

3A1670701255.jsonld | Selbstverstehen und Fremdverstehen : Diltheys Autobiographiekonzept als Grundlage der Geisteswissenschaften | For Wilhelm Dilthey, the process of self-understanding that comes to expression in autobiographical writing, has a model function for the historical understanding in general. In order to capture the systematic importance of literary self-description in Dilthey’s philosophy, the present study attempts to gain a comprehensive reconstruction of his autobiography concept from the collected writings and demarcates this reconstruction from other over-simplified research accounts. Autobiographical self-understanding can be captured as a constructive cognitive achievement that anticipates Paul Ricoeur’s concept of narrative identity to an astonishing extent. The understanding of others as a form of transposition of self-understanding is further related to contemporary empathy research and supplemented by current questions of literary philosophy. That way, an innovative picture of Dilthey's theory of understanding is created which remains compatible with many research approaches. Der Prozess des Selbstverständnisses, wie er in Autobiographien zum Ausdruck kommt, hat für Wilhelm Dilthey Modellfunktion für das geschichtliche Verstehen überhaupt. Um den systematischen Stellenwert der literarischen Selbstbeschreibung in Diltheys Philosophie zu erfassen, versucht die vorliegende Studie eine umfängliche Rekonstruktion seines Autobiographiekonzepts aus den gesammelten Schriften zu gewinnen und sie gegen vereinfachte Forschungsdarstellungen abzugrenzen. Das autobiographische Selbstverständnis kann als eine konstruktive Verstehensleistung aufgefasst werden, die Paul Ricoeurs Konzept narrativer Identität in einem erstaunlichen Ausmaß antizipiert. Das Verstehen anderer als eine Form der Transposition des Selbstverständnisses wird zur zeitgenössischen Empathieforschung und zu aktuellen Aspekten der Literaturphilosophie in Bezug gesetzt. Damit entsteht ein innovatives Bild von Diltheys Verstehenslehre, das anschlussfähig für viele Forschungsansätze bleibt. | [

3A865835527.jsonld | Einfluss von Kristallisationskinetik und Dynamik im Kristall und in der Schmelze auf die Strukturbildung teilkristalliner Polymere | chain dynamics; polyethyleneoxide; polycaprolactone; crystallisation kinetics; disentanglement time; crystallisation time; semi-crystalline structure; small angle X-ray scattering; entanglement density In dieser Arbeit erfolgt ein systematischer Vergleich der Zeitskalen der Kristallisationskinetik und Schmelzdynamik (τC und τD) sowie der Kristalldynamik (τR) und deren kombinierter Einfluss auf die Morphologie. In crystal-mobile Polymeren wie Polyethylenoxid (PEO) führt eine Reorganisation und Verdickung direkt an der Wachstumsfront zu einer lokal äquilibrierten topologischen Struktur der amorphen Phase. Für crystal-fixed Polymere wie Poly-Epsilon-Caprolacton (PCL) wachsen in Abwesenheit dieses Relaxationsprozesses die kristallinen Lamellen zufällig in die verschlaufte Schmelze. Die Bestimmung der für die Kristallisation und Reptation nötigen Zeitskalen von τC und τD erfolge experimentell. Für PEO wird außerdem die experimentell ermittelte Zeitskala der αc-Relaxation mit τC und τD verglichen. Die Morphologie von PEO hängt maßgeblich von der Kombination der Zeitskalen ab, wohingegen PCL weitgehend unbeeinflusst von einer Variation der Kristallisationsbedingungen bleibt. In PCL führt die Reorganisation der Ketten während der Kristallisation zu einer von τC/τD abhängigen Verringerung der Verschlaufungsdichte. Kettendynamik; Polyethylenoxid; Polycaprolacton; Kristallisationskinetik; Kristalldynamik; Entschlaufungszeit; Kristallisationszeit; teilkristalline Struktur; Röntgenkleinwinkelstreuung; Verschlaufungsdichte A systematic comparison of the timescales of crystallization kinetics and melt dynamics (τC and τD), as well as of the crystalline dynamics (τR) and their combined effect on the morphology is presented. In crystal-mobile polymers as polyethylenoxide (PEO), a reorganization and thickening directly at the growth front results in an equiibrated topological structure of the amorphous phase. For crystal-fixed polymers without this relaxation, such as poly-epsilon-caprolactone (PCL), crystalline lamellae grow randomly into the entangled melt. The timescales τC and τD are determined experimentally. Furthermore, for PEO the experimentally determined timescale of the αc-relaxation is compared with τC and τD. The morphology of PEO is largely dependent on the combination of the timescales, whereas PCL is widely unaffected by a change of the crystallization conditions. In PCL, the reorganization of chains during crystallization leads to a reduced entanglement density, depending on τC/τD. | [

3A727092774.jsonld | Prediction games : machine learning in the presence of an adversary | A main assumption in machine learning is that the data which are used to build a predictive model are governed by the same distribution as the data which the predictive model will be exposed to at application time. This condition is violated when future data are generated in response to the presence of a predictive model which is the case, for instance, in email spam filtering. In this thesis, we establish the concept of prediction games to handle such tasks: We model the interaction between a learner, who builds the predictive model, and a data generator, who controls the process of data generation, as an one-shot game. The game-theoretic framework enables us to explicitly model the players‘ interests, their possible actions, and their level of knowledge about each other. We study three instances of prediction games which differ regarding the order in which the players decide for their action. In case studies on email spam filtering we empirically explore properties of all derived models. We show that spam filters resulting from prediction games in the majority of cases outperform other existing baseline methods. | [

This work shows that ex gratia can neither always be reconciled with the legal principles of private insurance law, nor is it always unobjectionable from an economic perspective.

A comprehensive legal comparison with the United Kingdom provides insightful guidance on how to enforce the legal conformity of ex gratia.

3A689585462.jsonld | Shear design of straight and haunched concrete beams without stirrups | In spite of very long research activities with the first tests conducted by Mörsch in the 1920th, the design for shear of concrete members without transverse reinforcement is still not cleared. This may be demonstrated in the fact that most shear design procedures are not based on mechanical models but on empirical equations which show very big uncertainties. Thus very high safety factors have to be used. The problem of shear design exists primarily for slabs. In Germany numerous old concrete bridges show a lack of safety in transverse direction since the year 2001, when a new DIN-code was introduced. Furthermore the shear design principle of haunched concrete structures, as for example, cantilever slab of bridges, is hardly cleared, up to now. This research work aims to improve the understanding of the shear behaviour, to identify the significant shear resistance mechanisms and finally to develop new shear design models for practical use which is valid for straight and haunched concrete beams without stirrups. The essential, partially very different approaches known from the literature are analysed first and their accuracies are checked by a comparison with the test values from a shear database. Considerable differences appear between the arithmetic results and the test values. To study the behaviour of concrete members under high shear loads an extensive test program with 18 reinforced concrete beams without web reinforcement of different shear slenderness and inclination of compression chord was conducted. These experiments focused on haunched beams. It appears that the existing approaches describe the influence of an inclined compression chord on the shear capacity only in an insufficient manner. In some cases the design according to the DIN- or EC-Code results in unsafe values. To get a better understanding of the load-bearing mechanisms all tests are simulated by means of non-linear Finite Elements analysis with the programme ABAQUS. Very good agreement appears between the test results and those of FE-analysis including the load-deflection curves, the load bearing capacity and the crack patterns. Thus the developed numerical model can simulate the behaviour of reinforced concrete beams up to the ultimate limit state. The FE-analysis demonstrates that the shear forces are transferred in uncracked compression zone mainly. Therefore crack friction and dowel action plays no significant role on shear bearing capacity at the ultimate limit state. As a result of the FE-analysis and the test program, a shear resistance action of uncracked concrete part in the tension zone is firstly introduced to be one of the two main shear bearing actions of concrete structures without stirrups. Based on the theoretical and experimental investigations an easy analytic model is developed for the estimation of the shear capacity of straight and haunched reinforced concrete beams without stirrups. It shows more accurate results than the known approaches. Trotz langjähriger Forschungsaktivitäten, die ersten Versuche führte Mörsch 1920 durch, ist die Querkraftbemessung von Stahlbetonbalken ohne Querkraftbewehrung bislang unzurei-chend geklärt. Dies zeigt sich unter anderem darin, dass die meisten Bemessungsverfahren nicht auf einem mechanischen Modell sondern auf empirisch entwickelten Gleichungen ba-sieren, welche sehr große Streuungen und damit sehr hohe Sicherheitsfaktoren aufweisen. Das Problem der Querkraftbemessung besteht vor allem bei Platten. So weisen zahlreiche Massivbrücken in Deutschland nach der seit dem Jahre 2001 gültigen Norm rechnerisch eine zu geringe Tragfähigkeit in Querrichtung auf. Weiterhin ist die Querkraftbemessung von gevouteten Trägern, wie Sie beispielsweise bei Fahrbahnplatten von Brücken auftreten, bis-lang kaum geklärt. Diese Forschungsarbeit soll zu einem besseren Verständnis des Querkrafttragverhaltens von Stahlbetonbalken ohne Bügelbewehrung beitragen. Hierzu werden zunächst die wesentlichen aus der Literatur bekannten, teilweise sehr unterschiedlichen Rechenmodelle analysiert und deren Genauigkeit durch einen Vergleich mit den Versuchswerten aus einer Schubdatenbank bestimmt. Es zeigen sich erhebliche Streuungen zwischen den Rechen- und den Versuchs-ergebnissen. Zum Studium des Tragverhaltens wurden umfangreiche Versuche mit insgesamt 18 Stahlbe-tonbalken ohne Bügelbewehrung unterschiedlicher Schubschlankheit durchgeführt. Hierbei lag der Schwerpunkt bei gevouteten Trägern. Es zeigt sich, dass die bestehenden Ansätze den Einfluss eines geneigten Druckgurtes auf die Querkrafttragfähigkeit nur unzureichend beschreiben. Teilweise ergeben sich auf der unsicheren Seite liegende Rechenwerte. Zu einem genaueren Studium der Beanspruchungen und der Tragmechanismen werden die Versuche mittels stofflich nichtlinearer Finite Elemente Berechnungen mit dem Programm ABAQUS simuliert. Es zeigen sich sehr gute Übereinstimmungen zwischen Versuch und FE-Analyse. Dies trifft sowohl bei den Kraft-Weg-Verläufen, bei den Traglasten als auch bei den Rissbildern zu. Das entwickelte numerische Modell gibt somit das Verhalten von Stahl-betonbalken im Gebrauchs- und Grenzzustand zutreffend wieder. Die FE-Berechnungen zeigen, dass die Querkräfte im Wesentlichen in der ungerissen Druckzone übertragen werden und somit die Rissreibung im Grenzzustand der Tragfähigkeit keine wesentliche Rolle spielt. Die numerischen und experimentellen Untersuchungen haben weiterhin ergeben, dass die ungerissene Betonzugzone einen wesentlichen Anteil der Querkraft aufnimmt. Basierend auf den theoretischen und experimentellen Untersuchungen wird ein einfaches analytisches Modell zur Berechnung der Querkrafttragfähigkeit von geraden und gevouteten Stahlbetonbalken ohne Bügelbewehrung entwickelt, was erheblich genauere Werte als die bekannten Ansätze liefert. | [

The specific focus lies on the investigation of the feasibility and technology limits of customized silica AWG devices for high resolution near-infrared spectroscopy. In a series of theoretical and experimental studies, AWG devices of varying geometry, foot-print and spectral resolution are constructed, simulated using a combination of a numerical beam propagation method and Fraunhofer diffraction and fabricated devices are characterized with respect to transmission efficiency, spectral resolution and polarization sensitivity. The impact of effective index non-uniformities on the performance of high-resolution AWG devices is studied numerically. Characterization results of fabricated devices are used to extrapolate the technology limits of the silica platform. The important issues of waveguide birefringence and defocus aberration are discussed theoretically and addressed experimentally by selection of an appropriate aberration-minimizing anastigmatic AWG layout structure.

Eliot, and Wyndham Lewis have all, to varying degrees, been the subject of studies that explore their ideology. All too often, however, these studies have not tackled the issue adequately, limiting their analytical approach to fascism or other phenomena such as anti-Semitism. Frequently, they have also sought to exculpate these writers or to normalise their political tendencies in an effort to circumnavigate the dilemma of how to address the paradox of right-wing artists who are both harbingers and opponents of the imagined trajectory of progressive modernity. This interdisciplinary study analyses the connections between literary Modernism and right-wing ideology. Moreover, it is the first academic study to explore the reception of these Modernist authors by today's far right, seeking to understand in what ways they use strategic readings of Modernist texts to legitimise right-wing ideology. By raising fundamental questions about the relationship between aesthetics and politics, this study ultimately challenges its readers to see their cultural practices as political. It wants to make visible and problematize the interdependencies of right-wing ideology and cultural production as well as reception in order to explain the (far) Right as a phenomenon deeply rooted in European history and cultural development. It thus lays bare the misconceptions, the gaps as well as the complicity in the debate about right-wing ideology in literature | [

3A597868468.jsonld | Piriformospora indica released factors and its role in the molecular interaction with Arabidopsis thaliana | The interaction between P. indica and A. thaliana results in growth promotion and enhanced seed production. I studied the role of various P. indica-released factors in the interaction and the signalling pathways they activate. We describe the isolation of a growth-promoting factor from the cell wall of P. indica. The cell wall extract (CWE) induces a transient cytosolic Ca2+ elevation in the roots of Arabidopsis and tobacco plants expressing the Ca2+ bioluminescent indicator aequorin. The CWE and the fungus induce a similar set of genes in Arabidopsis roots, among them are genes with Ca2+ signalling-related functions. The CWE does not promote growth of P. indica insensitive lines and the growth promotion is abolished if the Ca2+ inhibitor BAPTA is added. The cellular Ca2+ elevations and are thus crucial for growth promotion, and Ca2+ signalling pathways are activated by incoming fungus. The CWE does not stimulate H2O2 production and the activation of defence gene expression, although it led to phosphorylation of mitogen-activated protein kinases (MAPKs) in a Ca2+-dependent manner. Thus, Ca2+ is likely to be an early signalling component in the mutualistic interaction between P. indica and A. thaliana similar to other interactions like AM symbiosis. P. indica releases isopentenyl-adenine (iP) and cis-Zeatin (cZ)-type cytokinins into axenic cultures, but elevated levels of cis Zeatin (cZ) isomers accumulate in colonized roots. However, our data clearly demonstrate that trans-zeatin (tZ) biosynthesis in Arabidopsis is required for the beneficial interaction as knocking out atipt1 atipt3 atipt5 atipt7 genes required for (tZ) biosynthesis results in no response to the fungus. The double mutant cre1ahk2 shows no growth response to P. indica. The CRE1 AHK2 receptor combination is thus crucial for the response to P. indica | [

Um den molekularen Mechanismus des krankheitsbedingten Verhaltens zu verstehen wird ein Polyglutamin mit 14 Aminosäuren, gekoppelt mit FRETChromophoren, verwendet und mit nicht-amyloiden Polypeptidketten verglichen. Die zeitaufgelöste FRET-Methode (trFERT) liefert Informationen über die Innerketten-Dynamik und -Dimension unstrukturierter Polypeptidketten. Für Q14 wurde eine extrem langsame Kettendynamik gefunden. Ein intramolekulares Netzwerk von Wasserstoffbrückenbindungen von Q14 könnte die langsamere Dynamik, die höhere konformationelle Aktivierungsenergie und die hohe Sensitivität zum Denaturierungsmittel GdmCl im Vergleich zu nicht-amyloidischen Modellpolypeptidketten erklären. Die hier gefundenen ungewöhnlichen Eigenschaften von Q14 auf monomerer Ebene sind ein wichtiger Schritt zum Verständnis des amyloidischen Charakters und zur Entwicklung zukünftiger therapeutischer Medikamente. Amyloid forming polypeptide chains such as polyglutamine tracts in proteins are discussed in the context of at least nine of expanded CAG repeat diseases e.g. the well-known Chorea Huntington disease. To understand the molecular mechanism of the disease-related behavior, a polyglutamine of 14 amino acids coupled with FRET chromophores were used and compared with non-amyloidic polypeptide chains. The time-resolved FRET method (trFERT) provides information on the intrachain dynamics and dimension of unstructured polypeptide chains. An extremely slow chain dynamics was found for Q14. An intramoleculare network of hydrogen bonds of Q14 may explain the found slow dynamics, the higher conformational activation energy and the high sensitivity to the denaturant GdmCl compared to non-amyloidic model polypeptide chains. The unusual properties of Q14 at the monomeric level are an important step to understand the amyloidic character and to develop future therapeutic drugs. | [

These genes encode for core components of the photosynthetic complexes and the chloroplast gene expression machinery, making most of them essential for the viability of the organism. The regulation of those genes is predominated by translational adjustments.

In addition to specific student traits and educational inequality caused by students’ background and migration history, educational systems and schools can also be contributing factors. Educational policy plays a central role in this regard. With the help of an interpretive policy analysis, this book shows that society and politics cast the deciding vote on how poor educational performance is defined. Such performance cannot be measured with purely statistical means. Falling rates of poor educational outcomes and rising graduation rates create an impression of a positive development. But this book shows that even as graduation rates rise, students’ knowledge and skills aren’t keeping pace with them. Teachers and policymakers play a major role in this development, not least through education reforms motivated by party politics. Bildungsarmut wird von einer Vielzahl von Einflussgrößen bestimmt. Neben individuellen Schülermerkmalen sowie herkunfts- und migrationsbedingten Bildungsungleichheiten gelten insbesondere das Bildungssystem und die Schule als mögliche Ursachen von Bildungsarmut.Eine zentrale Rolle im Kontext der Bildungsarmut nimmt die Bildungspolitik ein. Mit Hilfe der interpretativen Policy-Analyse zeigt die Arbeit, dass Gesellschaft und Politik maßgeblich beeinflussen, was unter Bildungsarmut verstanden wird. Bildungsarmut ist nicht rein statistisch erfassbar.Sinkende Quoten der absoluten Zertifikats- und Kompetenzarmut erwecken den Eindruck positiver Leistungsentwicklungen.

3A522593801.jsonld | Optimal control of the unsteady Navier-Stokes equations | My thesis is concerned with the study of optimal control problems for the non-stationary Navier-Stokes equations. These equations are a mathematical model to describe the behaviour of fluid flows. Simply speaking, we are considering the minimization of an objective function J(y, u) depending on control u and velocity field y subject to the state equation condensed to NS(y, u) = 0. This work is not the first on that particular subject. Many other authors have contributed their results. As a pioneering work stands the article of Abergel and Temam, where the first optimal control problem for fluid flows was considered, and where also the first existence and optimality conditions can be found. My thesis follows these classical attempt and will repeat known results, but also adds some new insight to this subject. At first an overview of the governing equations is given. It provides some functional analytic background material such as function spaces and weak solution concepts. Each control action requires a reaction of the flow. Though in real life this reaction should be unique, the mathematical theory does not yet provide such a result for three-dimensional problems for low regular data. In the two dimensional case this reaction is unique, and the mapping control-to-velocity field can be studied. It turns out that this mapping is even twice Fréchet differentiable, which enables us to use well-known Banach space programming techniques later on ... | [

3A1022368230.jsonld | Computational mass spectrometry of linear binary synthetic copolymers | The accurate characterization of synthetic polymer sequences represents a major challenge in polymer science. We present a computational approach to quantify the abundances of all sequences in a measured copolymer sample. The first step in our workflow is transforming mass spectra into copolymer fingerprints. Our method is based on linear programming and is capable of automatically resolving overlapping isotopes and isobaric ions. Peak intensities in matrix-assisted laser desorption/ionization spectra are influenced by mass and composition-dependent ionization. We demonstrate a method to correct the abundance bias. The second step in our workflow is interpreting the computed copolymer fingerprints using new Markov chain models for copolymerization kinetics: The Bernoulli and Geometric models. In contrast to previous Markov chain approaches to copolymerization, both models take variable chain lengths and time-dependent monomer probabilities into account and allow computing sequence likelihoods and copolymer fingerprints. We find that computing the models is fast and memory efficient. Then, we focus on the Geometric copolymerization model with reactivity parameters. First, several approaches to identify the optimal model parameters from observed fingerprints are evaluated using Monte-Carlo simulated data. A compromise between robustness and running time is found by exploiting the relationship between ordinary differential equations and the Geometric model. Second, we show that the model is also useful for copolymerizations involving termination and depropagation reactions. We then compute several copolymer statistics and compared them to the statistics obtained from Monte-Carlo simulations. Last but not least, we present our software framework COCONUT, which implements all algorithms presented in this thesis. Our software is freely available and provides a graphical user interface. COCONUT represents a step towards comprehensive computational support in polymer science. | [

3A1655773143.jsonld | Die Melamiyye von Rumelien : Sozial- und Ideengeschichte einer Sufi-Gemeinschaft | This study deals with the nineteenth-century Ottoman Sufi community of the Melâmiyye. It is the history of a social group for which modernization meant a crisis, which it sought to overcome with the help of trance and imaginary self-exaltation. Based on the texts of outstanding Melâmîs and the earliest critical observations, social and intellectual history are combined here in a way that reveals the general situation of Sufism in Turkey at the beginning of the Republican era. Diese Untersuchung handelt von der im 19. Jahrhundert entstandenen osmanischen Sufi-Gemeinschaft der Melâmiyye. Sie zeichnet die Geschichte einer Glaubensgruppe, für die die Modernisierung eine Daseinskrise bedeutete, welche sie mithilfe ekstatischer Mittel und imaginierter Selbsterhöhung zu bewältigen suchte. Ausgehend von den Texten herausragender Melâmîs sowie der frühesten Rezipienten wird hier Sozial- und Ideengeschichte auf eine Weise kombiniert, die den Blick auf die allgemeine Situation des Sufismus in der Türkei zu Beginn der Ära Atatürk freigibt. | [

3A1655625977.jsonld | Search for the Pentaquark Θ+ via the π−p → K−X Reaction at J-PARC | This theses reports on an experimental search for an exotic hadron, Θ+(1540) pentaquark, which is a genuine exotic hadron with a five-quark system of uuddsbar. The results of this book support that the existence of Θ+ was strongly constrained. The Θ+ pentaquark was searched for via the π- p → K- X reaction using a beam momentum of 2.01 GeV/c at the J-PARC hadron experimental facility, taking advantage of high-statistics and high-resolution compared with previous experiments, some of which claimed the evidence of Θ+. In order to realize a good missing-mass resolution of 2 MeV, the beam spectrometer and superconducting kaon spectrometer were constructed. No clear peak was observed in the missing mass spectrum of the π- p → K- X reaction, and the upper limit of the production cross section was found to be less than 0.28 μb/sr at the 90% confidence level in a mass region of 1500–1560 MeV/c2. This upper limit is an order of magnitude smaller than that of the previous KEK experiment. Compared with a theoretical calculation using the effective Lagrangian approach, the decay width of Θ+ was evaluated. The upper limits on the decay width were estimated to be 0.36 and 1.9 MeV for the Θ+ spin-parity of 1/2+ and 1/2-, respectively. These are quite small for a width of ordinary hadron resonances, and the existence of Θ+ was strongly constrained and is doubtful.
