Diffusion processes and event history analysis
No full textSeveral authors (e.g., Brüderl, Diekmann, Yamaguchi) derive hazard rate models of event history analysis from social diffusion processes. This paper also focuses on the integration of diffusion research and survival analysis. After a discussion of Diekmann's flexible diffusion model, we present an alternative approach which clarifies theoretical differences between popular rate models (e.g., the exponential model, log-logistic model, sickle model). Specifically, this approach provides a new rationale for the generalized log-logistic model in the sense of a flexible infection process. In cases with bell-shaped duration dependence, it thus allows a test for social contagion as a result of random contacts between actual and potential adopters. An application to divorce data serves as an illustration.

deutschsprachige Werbeschriften für die Auswanderung nach Nordamerika von 1680 bis 1760
No full textSoftcover, 284 S.: 23,00 €Softcover, 17x24Zwischen 1680 und 1760 sind insgesamt ca. 100.000 Deutsche nach Britisch-Nordamerika ausgewandert. Um diese aus ihren fest gefügten dörflichen Gemeinschaften zu lösen, setzten die Kolonisatoren gedruckte Werbepamphlete ein. Nach einer kurzen Einleitung über die Umstände der Migration werden vierzehn dieser Schriften vorgestellt. Ersichtlich wird, dass zuerst von Pennsylvanien aus nach deutschen Siedlern gesucht wurde. Dann betrieben die südlichen Kolonien die Werbung, die ihren Höhepunkt in langjährigen Kampagnen für South Carolina und Georgia fand. Sogar das eigentlich streng auf kulturelle Geschlossenheit bedachte Massachusetts setzte schließlich Agenten in Bewegung. Die besorgten Obrigkeiten initiierten Gegenpamphlete, um das »Auswanderungsfieber« einzudämmen. Den Abschluss der Arbeit bildet eine Darstellung der damaligen Sichtweise über das zu besiedelnde Gebiet. Dabei wird deutlich, dass es nicht als Europa völlig fremd, sondern als Gegenwelt zum Umfeld des jeweiligen Autors und seiner Leser gesehen wurde
Stellvertretung in Gesundheitsangelegenheiten
No full textSoftcover, 194 S.: 25,00 €Softcover, 17x24Eine ärztliche Maßnahme tastet die leibliche und gegebenenfalls die seelische Integrität eines Menschen an. Die Bestimmung darüber ist ein Teil der Personalität eines Menschen. Der Einzelne kann sein Selbstbestimmungsrecht nur wahrnehmen, wenn seine Entscheidung Voraussetzung gerechtfertigten ärztlichen Handelns ist. Kann ein Volljähriger auf Grund einer Krankheit oder Behinderung darüber nicht befinden, können Entscheidungen durch einen rechtsgeschäftlichen Vertreter – einen Bevollmächtigten – oder durch einen gesetzlichen Vertreter – einen Betreuer – getroffen werden. In der vorliegenden Untersuchung werden die unterschiedlichen Vertretungsregelungen im Bereich der Gesundheitsangelegenheiten dargestellt. Es wird zudem geprüft, ob es das Selbstbestimmungsrecht des Einzelnen gebietet, eine weitere „automatische“ Vertretungsmöglichkeit für nahe Angehörige zu normieren. Es wird auch erwogen, auf welche Grundlage eine entsprechende Befugnis gestützt werden, in welchen Fällen und unter welchen Voraussetzungen sie eingreifen könnte.A medical measure influences the physical and mental integrity of the affected people. The right of determination is also part of a person’s personality. The individual can exercise his right of self determination only when its decision conditions and justifies medical practice. Is an adolescent due to an illness or disability not able to excersise decisions, these have to be made by a representative of legal transactions - an agent - or taken by a legal representative - a supervisor. In this study, the different representation schemes on health matters are presented
Rebel with a cause : Dutch children’s author Miep Diekmann as the personification of ’68
No full textThe rebellious spirit of 1968 was characterised, among other things, by a strong aversion to authority of any form. In Dutch children’s literature, this spirit is personified by the author Miep Diekmann. From the end of the 1950s until the end of the 1980s, Diekmann contested all kinds of social injustice, both in her children’s books and in her critical work. This article discusses how she challenged the status quo in Dutch children’s literature, firstly through her efforts to improve the cultural status of children’s literature, and secondly through writing books with a different view of the world than the one with which children were then familiar. In interviews, reviews, and discussions with politicians, she successfully appealed for more academic and critical attention for books for young readers. With her children’s books she wanted to make her readers think independently about all kinds of social injustice. Whereas in her first books a tension can be observed between her ambition to make children aware of forms of inequality and her intention to let her reading audience judge for themselves, in her later novels, in particular in De dagen van olim, [The Days of Yore] (1971), she presents social injustice in a way that leaves more to the imagination of her readers

On Common Intervals with Errors
No full textChauve C, Diekmann Y, Heber S, Mixtacki J, Rahmann S, Stoye J. On Common Intervals with Errors. Forschungsberichte. Bielefeld: Technische Fakultät der Universität Bielefeld; 2006.The information that groups of genes co-occur in several genomes provides a basis for further comparative genomic analysis. The task of finding such constellations, mostly referred to as gene clusters, has led to various models of increasing generality. A central feature to enhance the biological relevance of their definition when applied to real genomic data is to allow for slight differences in the gene content within a cluster, thus not only considering groups of exact equality. We contribute a model defining gene clusters as common intervals with errors and discuss different representations and the corresponding problems resulting for the search procedure
