Although poorer self-rated health (SRH) is associated with increased mortality, less is known about its impact on functioning. This study evaluated whether poorer SRH was associated with decline in walking speed and whether caregiving, often considered an indicator of chronic stress, modified this relation. The sample included 891 older US women from the Caregiver-Study of Osteoporotic Fracture...

We consider scheduling policies for maxmin fair allocation of bandwidth in wireless adhoc networks. We formalize the maxmin fair objective under wireless scheduling constraints. We propose a fair scheduling which assigns dynamic weights to the flows such that the weights depend on the congestion in the neighborhood and schedule the flows which constitute a maximum weighted matching. It is possi...

Class-based traffic treatment frameworks such as Differentiated Service (DiffServ) have been proposed to resolve the poor scalability problem in the flow-based approach. Although the performance is differentiated in a class-based basis, the performance seen by individual flows in the same class may differ from that seen by the class and has not been well understood. We investigate this issue by...

BACKGROUND Social support resources are thought to buffer stressful life events and have been associated with numerous health outcomes in industrialized countries. Because the nature of supportive relationships varies by culture and social class, we studied the relationship of informal social support and networks to self-rated health among low-income women in northeastern Brazil. METHODS Part...

This study investigates the relation between overweight/obesity and self-rated health (SRH), and whether this relation varies by social factors. Data was taken from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS, baseline 2003‒2006). For the definition of overweight and obesity, body mass index was calculated based on standardized height and weight measur...

A comparative study conducted in Australia and the United States examined people’s responses to protagonists who were either born rich or poor and who ended up either rich or poor as adults. Results reveal some cross-cultural similarities and some differences. Specifically, people in both countries perceive initially poor and subsequently rich individuals as more competent and likeable than ini...
