Coxsackie B viruses and the kidney--a neglected topic

Coxsackie B viruses types 1-6 (CVB1-6) occur worldwide and cause a broad spectrum of diseases, including myocarditis and aseptic meningitis. Although renal damage due to CVB has been suspected since the 1950s, these agents are only rarely searched for in today's clinical nephrological practice. Nevertheless, CVB can infect mesangial cells. Furthermore, infections with these viruses lead to a histological picture resembling mesangioproliferative glomerulonephritis and IgA-nephropathy in mice. In the present article, we provide an overview of this largely neglected topic, and of the slowly and steadily increasing evidence suggesting a link between coxsackieviral infections and kidney diseases.

Non-comparative versus Comparative Advertising of Quality

Two firms produce a good with a horizontal and a vertical character- istic called quality. The difference in the unobservable quality levels determines how the firms share the market. We consider two scenar- ios: In the first one, firms disclose quality; in the second one, they send costly signals thereof. Under non-comparative advertising a firm advertises its own quality, under comparative advertising a firm adver- tises the quality differential. In either scenario, under comparative ad- vertising the firms never advertise together which they may do under non-comparative advertising. Moreover, under comparative advertis- ing firms do not advertise when the informational value to consumers is small.

The Nature of Sustainable Consumption and How to Achieve it. Results from the Focal Topic "From Knowledge to Action – New Paths towards Sustainable Consumption"

Is the online trade with second-hand products changing individual consumer behaviour? What is the sustainability potential of this activity? How can daily energy-consuming routines at the workplace be changed? Do major changes in the course of people's lives represent opportunities to modify their consumer behaviour towards greater sustainability? These are only some of the research questions studied in the focal topic "From Knowledge to Action - New Paths towards Sustainable Consumption" which is funded by the German Federal Ministry of Education and Research (BMBF) as part of the "Social-ecological Research Programme" (SÖF). This book gives an insight into the research results of the ten project groups. Their diversity highlights that there is much more to "sustainable consumption" than the simple purchase of organic or fair trade products.In addition, overarching conceptual and normative issues were treated across the project groups of the focal topic. Developed collaboratively and moderated by the accompanying research project, the results of the synthesis process are also presented here, as for example how the sustainability of individual consumer behaviour can be evaluated,or which theories of action are particularly useful for specific consumer behaviour phenomena.
