Although standard economics textbooks are seldom interested in production networks, modern economies are more and more based upon supplier/customer interactions. One can consider entire sectors of the economy as generalised supply chains. We will take this view in the present paper and study under which conditions local failures to produce or simply to deliver can result in avalanches of shortage and bankruptcies and in localisation of the economic activity. We will show that a large class of models exhibit scale free distributions of production and wealth among firms and that regions of high production are localised.

The peculiar German football governance structure may be well suited to prevent integrity problems resulting from multiple club ownership or from ownership by "undesired'' persons or entities. However, this effect comes at a price. In the vacuum of power generated within large member associations, residual rights of control are de facto allocated to representatives who do not hold residual claims. Because these representatives externalize substantial parts of the risk associated with investment decisions, they are particularly ill-suited for managing the business of professional football, which has been transformed into a "gamble on success'' by ever-increasing revenue differentials between winners and losers. At the same time, low accounting standards for members clubs, combined with "soft'' law enforcement, invite club representatives to hide their consumption on the job behavior until their clubs are insolvent.

Human cooperation is unparalleled in the animal world and rests on an altruistic concern for the welfare of genetically unrelated strangers. The evolutionary roots of human altruism, however, remain poorly understood. Recent evidence suggests a discontinuity between humans and other primates because individual chimpanzees do not spontaneously provide food to other group members, indicating a lack of concern for their welfare. Here, we demonstrate that common marmoset monkeys (Callithrix jacchus) do spontaneously provide food to non-reciprocating and genetically unrelated individuals, indicating that other-regarding preferences are not unique to humans and that their evolution did not require advanced cognitive abilities such as theory of mind. Because humans and marmosets are cooperative breeders and the only two primate taxa in which such unsolicited prosociality has been found, we conclude that these prosocial predispositions may emanate from cooperative breeding.

This thesis presents the development of a new approach for building a person following robot that is able to operate in an unknown environment facing real life situations. Infrared receivers are used to identify and locate a target person, who is equipped with infrared diodes. This approach has the following advantages: reliable identification of the target person, cheap design and good noise tolerance. The process of implementing the new person following strategy revealed several inherent restrictions of the existing platform, which thus had to be revised. Therefore the approach could no be implemented completely. Nevertheless it is still promising and should be pursued in continuation of the RoboSuitcase project.

Given a 3D-Scanner based on a static construction with a turntable, the goal of this project is to free the dependency on static geometries to build a handheld 3D laser scanner. As hardly any geometrical parameters have been provided, the key to implement the handheld scanner is to work out the position of the camera in space as this is the basis for every calculation. In addition the laser plane describing the laser line crossing the camera view needs to be calculated to determine the location of detected laser points relative to the camera. When combining the camera position with the projected laser points of continuous images the shape of the target object can be extracted.

Das sesamDB Projekt ist ein Teilprojekt der interdisziplinären Langzeitstudie sesam zur Ätiologie von psychischen Erkrankungen. Es beschäftigt sich mit der Entwicklung der Datenbank fu?r wissenschaftliche und administrative Daten von sesam sowie der Implementierung verschiedener Clientanwendungen. Um die in sesam erhobenen Daten mittels Statistiksoftware analysieren zu können, wurde eine Applikation entwickelt, die Daten aus der sesamDB in gängige Statistikformate exportiert. Eine grafische Benutzeroberfläche ermöglicht es dem Anwender, die benötigten Daten ohne Kenntnisse u?ber den Datenbankaufbau oder Datenanfragesprachen zu erhalten. Diese Arbeit enthält eine Zusammenstellung verwandter Arbeiten sowie den Entwicklungsprozess und die Architektur des Exportprogramms, Sesam Export Manager.The sesamDB Project is a subproject of the interdisciplinary long time study sesam about the etiology of mental health. Its main task is to develop a database for scientific and administrative data for sesam as well as the implementation of client applications. In order to analyze the stored data with statistical analysis software, Sesam Export Manager has been built to extract data from sesamDB to data types of popular statistics applications. The therefore developed graphical user interface helps the user to obtain the data he needs without having knowledge of the underlying database schemes or query languages. This paper contains a composition of related work, the development process and the architecture of Sesam Export Manager.
