Chinese artists, activists, and netizens are pioneering a new order of pornographic representation that is in critical dialogue with global entertainment media. Jacobs examines the role of sex-positive feminists and queer communities to investigate pornography's "afterglow" (a state of crisis and decay within digital culture).

Medical schools currently use specialist perspectives on psychiatric disorders to train physicians, nurses and health professionals. This results in a lack confidence among non-psychiatric health professionals, which reduces their ability to manage common mental health conditions in primary care and secondary hospitals. This book is a practical guide to common mental health conditions encountered in general medical practice.

Past and future development as well as possibilities for influencing the process of retirement are discussed, in particular effects on the labour market (supply and demand, behaviour of workers and firms, concerning human resource management and occupational pensions), financing of social security and income of workers. Decisions concerning earlier or postponed, full or partial retirement are the main topic stressing the central role of firms' decisions depending e.g. on their view of the productivity of the elderly. Reports on Scandinavian countries (Sweden, Denmark, Finland) in particular on their approach for partial retirement are included as well as papers discussing possibilities to stop the trend of early exit from the labour force and how to give incentives for a longer working life (e.g. by changes in social security). These topics are discussed in the view of structural changes in demography, economy and society, using - among other - the US and West Germany as examples. The papers point out the necessity to look at retirement as a process (in a life cycle perspective, requiring longitudinal data for empirical research) and in a perspective integrating the different aspects involved.

Von jeher haben vViederkehrerscheinungen das Interesse nachdenk licher Leute gefunden und insbesondere mathematische Untersuchungen angeregt. Periodisches Zahlen verbinden wir mit der Regelmassigkeit eines Rhythmus, Translationsgruppen mit der Wiederkehr in Fries mustern, und die Umlaufe der Planeten verlangten Newton die Erfin dung der Infinitesimalrechnung ab. Es geht aber nicht nur darum, beobachtete Wiederkehr in mathematischen Modellen nachzuzeichnen, sondern auch um die grundsatzliche Frage: Warum muss Wiederkehr sein? Genauer: Welche Eigenschaften eines mathematischen Modells erzwingen das Auftreten von Wiederkehrerscheinungen ? Die Antwort der Mathematik auf diese Frage sind die sog. vVieder kehrsatze, von denen wir die wichtigsten in diesem Band in typischer Gestalt, wenn auch nicht immer in grosstmoglicher Allgemeinheit vor stellen. Sie lassen sich nach der Art der zugrunde gelegten Strukturen unterscheiden. Arbeitet man mit rein topologischen Mitteln, so befindet man sich in der sog. topologischen Dynamik, der unser erster Beitrag gilt. Der hier bewiesene Wiederkehrsatz 3.9 stutzt sich vor allem auf die Kom paktheit des zugrunde liegenden Raums und zeigt die Existenz fast periodischer Bewegungen. Starre Bewegungen eines speziellen Kompaktums, namlich der Kreislinie (oder allgemeiner: eines Torus), sowie einen strengeren Fast periodizitatsbegriff untersucht der zweite Beitrag uber Gleichverteilung mod 1, in dem wir Weyls beruhmten Satz beweisen, und den Leser auch etwas in die Mittelwerttheorie der fastperioiischen Funktionen ein fuhren."
