Bielefeld University (German: Universität Bielefeld) is a university in Bielefeld, Germany. Founded in 1969, it is one of the country's newer universities, and considers itself a "reform" university, following a different style of organization and teaching than the established universities. In particular, the university aims to "re-establish the unity between research and teaching", and so all its faculty teach courses in their area of research. The university also stresses a focus on interdisciplinary research, helped by the architecture, which encloses all faculties in one great structure.
We are used to calling most developing countries overpopulated and consi dering some industrialized countries (like West Germany) "threatened by underpopulation". Analogous population policies with different objecti ves are discussed. However, none of the measures suggested can be justi fied or evaluated without an implicit concept of optimum population, a notion which has attracted attention ever since economics was made a science. The relevance of the subject and the recent rise in interest by popula tion economists has motivated the organization of a conference on "Opti mal Population" in Bielefeld, where most of this book originates.

The 4th IAPR TC3 Workshop on Arti?cial Neural Networks in Pattern Rec- nition, ANNPR 2010, was held at Nile University (Egypt), April 11 13, 2010. The workshop was organized by the Technical Committee on Neural Networks and Computational Intelligence (TC3) that is one of the 20 technical comm- tees (TC) of the International Association for Pattern Recognition (IAPR). The scope of TC3 includes computational intelligence approaches, such as fuzzy s- tems, evolutionary computing and arti?cial neural networks and their use in various pattern recognition applications. The major topics of ANNPR are supervised and unsupervised learning, f- ture selection, pattern recognition in signal and image processing, and appli- tions in data mining or bioinformatics. High quality across such a diverse ?eld of research is achieved through a rigorous and selective review process. For this workshop, 42 papers were submitted and 23 of them were selected for inc- sion in the proceedings. The workshop was enriched by three invited talks given by Barbara Hammer, University of Bielefeld, Germany, Amir F. Atiya, Cairo University, Egypt, and Mohamed Kamel, University of Waterloo, Canada. We would like to thank all authors for the e?ort they put into their subm- sions, and the Scienti?c Committee for taking the time to provide high-quality reviews and selecting the best contributions for the ?nal workshop program. Special thanks are due to the members of the Nile University Organizing C- mittee,AhmedSalah,AmiraElBaroudy,EsraaAly,HebaEzzat,NesrineSameh, Rana Salah and Mohamed Zahhar for their indispensable contributions to the registration management and local organization.
Seminar paper from the year 2013 in the subject Business economics - Supply, Production, Logistics, grade: 1,3, Bielefeld University, course: dynamic games in industrial organization, language: English, abstract: In our industrialized world we are confronted with very complex goods. Most of them became part of our everyday life like cars, planes and so on. These products consist of several components with high technological requirements to guarantee the quality of the final product. For example, the production of a high developed plane, as the Airbus A380, needs many special single components like turbines, wings, etc. These vital intermediate goods could either be purchased by foreign firms or be produced by the downstream assembler itself, respectively by an owned subunit. A view on the vertical structure among different downstream firms of different products shows that the share in purchased goods from foreign upstream firms varies widely. Since the components are very specifc, the number of upstream firms which produce one vital intermediate input is of course limited. In turn, the specific component could be purchased by less, mostly just one, consumer. A turbine manufactured for the A380, for instance, could not be used by another assembler than Airbus. A downstream firm is faced by deciding whether it should either integrate upstream units and become the owner of them or to sell some upstream firms, respectively let them stay independent, with respect to maximize its own profit. To provide an answer to the optimal behavior of an assembler, with respect to in- tegrate or to separate upstream units, I will use a model where the downstream firm is a monopolist in the final good market and needs a fixed number of vital intermediate inputs in fixed proportions to produce the final product. This model is relatively new and not being discussed by many authors. It was first examined in 2008 by Laussel. We will see that there exist two effects that influence the decision of the downstream firm. If the independent upstream suppliers have some positive bargaining power, they will sell their produced goods to a price above their costs. That causes the double marginalization effect, because the upstream firms do not account for the effect of its mark-up on the downstream firm. Furthermore an independent supplier, with a positive bargaining power, has a decreasing effect on the prices of the components supplied by the other independent upstream firms, because of the perfect complementary character of the intermediate goods. A high number of independent suppliers yields to relatively low input prices of the particular upstream firms.
Bachelorarbeit aus dem Jahr 2005 im Fachbereich Gesundheitswissenschaften, Note: 2,0, Universität Bielefeld, Sprache: Deutsch, Abstract: Mit der Verabschiedung der Ottawa Charta durch die World Health Organization (WHO) im Jahre 1986 hat die Bedeutung einer gezielten Förderung der physischen Gesundheitsressourcen ebenso zugenommen wie jene der psychischen und sozialen Ressourcen. Es wird betrachtet, unter welchen Kriterien Gesundheitssport und Sportaktivität zu sehen sind. Bezüglich der Sportteilnahme werden Erklärungstheorien und -modelle aufgeführt sowie Interventionstheorien. Anschliessend geht es um Motive und Determinanten sportlicher Aktivität. Das alles soll dazu beitragen, Sportverhalten besser verstehen zu können und ist bei der Betrachtung des Ausmasses der Sportaktivität in Deutschland sowie der Potenziale der Gesundheitsförderung im letzten Kapitel der Arbeit von Bedeutung. Weiter wird dargestellt, wie Sportvereine in Deutschland organisiert und strukturiert sind. Welche Rolle nehmen Sportvereine in der Gesundheitsförderung ein und welche Konzepte und Programme gibt es? Soziale Präventionsträger und auch Sportvereine sollen gemäss dem Präventionsgesetzentwurf Leistungen zur Verhaltensprävention erbringen, um die Veränderung gesundheitsbezogener Verhaltensweisen der Versicherten zu unterstützen und damit gesundheitliche Risiken zu vermindern sowie gesundheitliche Ressourcen und Fähigkeiten zu stärken. Wenn man 2004 nach der Bestandserhebung des Deutschen Sportbundes (DSB) von circa 27,5 Millionen Mitgliedern in Sportvereinen ausgehen kann, dann kann sich Gesundheitsförderung im 'Setting Sportverein' an viele Menschen in Deutschland richten. Dabei ist in der Arbeit von Interesse, welche bisherigen und aktuellen Gesundheitsförderungsmassnahmen es im Zusammenhang mit Sportvereinen gibt. Inwiefern ist Gesundheitsförderung durch sportliche Aktivität als gemeinsames Ziel der Sportwissenschaften und von Public Health zu sehen? Inwieweit verfolgen und erreichen bisherige Gesundheitsförderungsstrategien des Deutschen Sportbundes und seiner Sportvereine diese Ansätze und Ziele? Oder konkret formuliert: genügen Sportvereine dem Gesundheitsförderungsansatz, vor allem dem Settingansatz von Public Health und wenn ja, in welcher Form? Die Arbeit soll abschliessend eine Einschätzung zu den Potenzialen der Gesundheitsförderung durch Sportvereine im Public Health-Kontext liefern.
Two decades after the publication of Clifford and Marcus' volume Writing Culture, this collection provides a fresh and diverse reassessment of the debates that this pioneering volume unleashed. At the same time, Beyond Writing Culture moves the debate on by embracing the more fundamental challenge as to how to conceptualise the intricate relationship between epistemology and representational practices rather than maintaining the original narrow focus on textual analysis. It thus offers a thought-provoking tapestry of new ideas relevant for scholars not only concerned with 'the ethnographic Other', but with representation in general.

This volume presents the invited lectures of a conference devoted to Infinite Length Modules, held at Bielefeld, September 7-11, 1998. Some additional surveys have been included in order to establish a unified picture. The scientific organization of the conference was in the hands of K. Brown (Glasgow), P. M. Cohn (London), I. Reiten (Trondheim) and C. M. Ringel (Bielefeld). The conference was concerned with the role played by modules of infinite length when dealing with problems in the representation theory of algebras. The investi gation of such modules always relies on information concerning modules of finite length, for example simple modules and their possible extensions. But the converse is also true: recent developments in representation theory indicate that a full un derstanding of the category of finite dimensional modules, even over a finite dimen sional algebra, requires consideration of infinite dimensional, thus infinite length, modules. For instance, the important notion of tameness uses one-parameter fami lies of modules, or, alternatively, generic modules and they are of infinite length. If one tries to exhibit a presentation of a module category, it turns out to be essential to take into account the indecomposable modules which are algebraically compact, or, equivalently, pure injective. Specific methods have been developed over the last few years dealing with such special situations as group algebras of finite groups or noetherian rings, and there are surprising relations to topology and geometry. The conference outlined the present state of the art.
