This note, which summarises a series of observations made in two Mediterranean ponds and many waters in Madagascar, sought to highlight the evolution of highly resilient fish populations introduced in environments where they find an empty or inadequately occupied niche. In the case of Sandre, as a result of the very exceptional abundance of aerials in two colonised ponds, the Olivier pond and the Vaccarès pond, the fish found a niche that was perfectly suited to it. But the "ideal" and over-abundant food stock once reduced, Sandre 's population fell all the more as the Volterra law on the disturbance of averages was acting through intensive fisheries. There are other examples of explosive developments, followed by regression, for newly introduced species in Madagascar: various species of tilapia and blackbass. For the various species of tilapia, in particular, the final balance towards which the population tends depends very much on the diet of the species introduced and on the speed with which the food consumed can be revived. The cases of herbivores and omnivores-planktonophages are compared. When it comes to the introduction of fish, it is therefore essential to look at the problem from an ecological niche point of view and to be familiar with the trophic relationships of the biocnosis into which a new species is introduced with neighbouring biocnoses. The above mentioned Mediterranean and Malagasy examples suggest that in cases of occupation of an empty niche (or of a poorly occupied niche) by high-resilience fish with a large, perfectly suitable food stock on arrival, their population undergoes a phase of explosive development predicted by the Pearl S-curve, followed by a regression, with the population subsequently stabilising to a level that is consistent with the trophic possibilities per manent of the environment. ; International audience Changes in the abundance of the Pike-perch Stizostedion ( Sander ) lucioperca, following its penetration into the Etang de l'Olivier and Etang du Vaccarès (Provence), ...

"Philosophical inquiry into the theory and practice of responsibility is a major and fast-growing area of study. It spans perennial philosophical, political, and legal questions about free will and agency as well as more recent, controversial topics such as coercion, ignorance, and responsibility for historical injustices. The Routledge Handbook of Philosophy of Responsibility is an outstanding survey and exploration of these issues and more. Comprised of forty-one chapters by an international team of contributors, the Handbook is divided into three clear parts - on the history, theory, and practice of responsibility - within which the following key areas are examined: responsibility and wrongdoing responsibility and determinism the scope of responsibility individuals and society the concepts of responsibility the conditions and challenges of responsibility being and holding responsible the ethics and politics of responsibility responsibility in the law. Including suggestions for further reading at the end of each chapter, The Routledge Handbook of Philosophy of Responsibility provides an extremely useful guide to the topic. It will be valuable reading for students and researchers in philosophy and applied ethics, as well as for those in related disciplines such as politics, law, and policymaking"--

Es gehört zur Sprachbegabung des Menschen, daß er das Wort auch als Waffe einsetzt - sei es zum Angriff oder zur Verteidigung, sei es, um sich abzureagieren, den anderen in die Schranken zu weisen. Der 'Möglichkeiten sind viele. Diese menschlichste aller menschlichen Aggressionsformen scheint den Forschem bisher kaum einer gründlichen Betrachtung wert gewesen zu sein.

In diesem Aufsatz wird anhand einer Fallstudie das Policy-Making der schweizerischen Berufsbildungspolitik analysiert. Als Fallstudie dient die Überführung der Gesundheitsberufe in die Bundeskompetenz im Zusammenhang mit dem neuen Berufsbildungsgesetz. In einer diskurstheoretischen Perspektive zeigt sich, dass es beim Fallbeispiel zwar um die konkrete Verschiebung vom einen in den anderen Kompetenzbereich und darüberhinaus um die Durchsetzung eines bestimmten Berufsbildungsmodells geht. Zugleich aber dreht sich das Policy-Making darum, die Berufsbildung als spezifische, sozial ausgehandelte Wirklichkeit zu bestätigen, sie abzugrenzen und ihre Identität zu behaupten. (DIPF/Orig.) ; In this article Swiss policy concerning vocational education will be analysed by means of a case study. The case study used was that of the transfer of the responsibility for medical careers from the medical association to the federal level. Here the new federal law concerning vocational education was also considered. From a discourse theoretical perspective it is shown that the case study deals with the concrete displacement from one competence area to another. It further deals with the planning of a certain vocational training model. At the same time policy making turns around and confirms vocational training to be a specific social negotiated reality, to confine it and create its own identity. (DIPF/Orig.)
