OBJECTIVES To examine the relationships between loneliness, social and health behaviors, health, and mortality among older adults in China. METHOD Data came from a nationally representative sample of 14,072 adults aged 65 and older from the 2002, 2005, and 2008 waves of the Chinese Longitudinal Healthy Longevity Survey. A cross-lagged model combined with survival analysis was used to assess t...

We examined the relation between leisure activities and the risk of dementia in a prospective cohort of 469 subjects older than 75 years of age who resided in the community and did not have dementia at base line. We examined the frequency of participation in leisure activities at enrollment and derived cognitive-activity and physicalactivity scales in which the units of measure were activity-da...

We explored whether gender moderated the influence of other factors on solo spousal caregiving. The subsample (N = 452) from the AHEAD study included elderly care recipients (CRs) receiving IADL assistance and their spouses. Logistic regression modeled the likelihood of solo spousal IADL care. Gender moderation was tested by product terms between CRs' gender and measures of partners' health, po...

Oxazine derivatives are significant class of heterocycle compounds, which has involved much synthetic attention due to their extensive variety of pharmacological activities. Oxazine is a heterocyclic compound can be formally derived from benzene, and its reduction products, by suitable substitution of carbon (and hydrogen) atoms by nitrogen and oxygen. In the last few years oxazine derivatives ...

Language is a tool, and hence directly affects the outcome of any activity undertaken. This paper describes such a tool together with the proposition that it will improve the use of the concept of contradictions as a conceptual tool within activity theory. The authors find that within their own research activity, adopting a concise but descriptive notation has greatly enhanced the quality of co...

Two factors presumed to affect the behavioural response of cattle (Bos taurus) to artificial weaning were investigated: the termination of nursing, and the physical separation of cows and calves. A two-stage process was used to disconnect these traditionally linked components. First, the behaviour of cows and calves was quantified in response to preventing nursing by having calves wear an antis...

This paper describes the results from the FP7 HELP project, which investigated the potential of emerging wireless communication technologies and potential synergies between mobile public safety and commercial networks to enhance the communication capabilities of public safety users. The paper identifies the current trends and challenges for wireless communications in the public safety domain, t...

This document, presents a synthesis of the pedagogical methodological work done within the framework of the KP-LAB (Knowledge Practices Laboratory) project, which, together with a consortium of 22 research institutions from different European countries, has been investigating the concept of trialogical learning for the past four years. We begin with a description of the underlying approach of t...

This paper shows how one can infer the nature of local returns to scale at the inputor output-oriented efficient projection of a technically inefficient inputoutput bundle, when the inputand output-oriented measures of efficiency differ. Journal of Economic Literature Classification: D2, C6
