This article argues that the social quality approach can be usefully applied to studying “models of elderly care“ that enhance the wellbeing of the elderly and empower them to participate in social activities. Examining three cases in Japan and another three cases in e Netherlands, the study identifies actors, institutions and processes that have provided services for the elderly, highlighting the importance of history and culture in influencing the “social“ of the elderly. The article deals with a range of opportunities (...) and possibilities for optimizing care for the elderly, both as individuals and as a group, through promoting their social inclusion, social cohesion, socio-economic security and social empowerment. Grounded in community networks, as well as in social and intergenerational interaction, these “models“ demonstrate how care-givers, including nurses and family members, are also empowered in these processes. These discussions, reflecting empirical reality and conceptual insights, provide the basis of sustainable welfare policies that improve the social quality of the elderly. (shrink)

This is an attempt to view the most basic and fundamental part of modern logic from a perspective which shares no grounds with any established schools of philosophical logic, in that the truth and falsehood as judged by means of human interventions is denied and the notion of logical dimensions is introduced. It establishes the minimum irrefutable logical structure and proceeds to found the relations between logic and geometry. The description of symmetry creates and simultaneously constrains the logical structure, whereas (...) symmetry itself can only be postulated. (shrink)

Valuable insights into eukaryotic regulatory circuits can emerge from studying interactions of bacterial pathogens such as Helicobacter pylori with host tissues. H. pylori uses a type IV secretion system (T4SS) to deliver its CagA virulence protein to epithelial cells, where much of it becomes phosphorylated. CagA's phosphorylated and non‐phosphorylated forms each interact with host regulatory proteins to alter cell structure and cell fate. Kwok and colleagues1 showed that CagA destined for phosphorylation is delivered using host integrin as receptor and H. (...) pylori's CagL protein as an integrin‐specific adhesin, and that CagL–integrin‐binding activates the kinase cascade responsible for CagA phosphorylation. This research contributes to understanding infectious disease and the control of cell fates. BioEssays 30:515–520, 2008. © 2008 Wiley Periodicals, Inc. (shrink)
