This study investigated attrition in a 6-month physical activity intervention for older adults. The program was based on the social-cognitive theory incorporating self-efficacy factors. Two hundred forty-eight insufficiently active 65- to 74-year-olds were recruited from the Australian federal electoral roll. The intervention comprised walking and strength and flexibility exercises and was conducted in 30 local neighborhoods where the participants resided. Characteristics of individuals lost to attrition (n = 86, 35%) were compared with those of program completers (n = 162, 65%). Logistic-regression analysis showed that those lost to attrition came from areas of lower socioeconomic status, were overweight and less physically active, and had lower walking self-efficacy scores and higher loneliness scores. The results suggest that early assessment of these characteristics should be undertaken to identify individuals at risk of attrition, to improve retention, and to avoid potential bias.  相似文献

Rural population density has a very significant independent influence over important socio-economic and demographic characteristics of developed world rural communities. Additionally, it is a fundamental variable in public policy and planning, both expressing and influencing the relative cost-efficiency of servicing populations. Yet density is itself produced by more fundamental qualities (e.g. environmental resources, nature and time of colonisation) which may themselves change over time. Treating rural population density as a dependent variable produced by a wide variety of factors, we build and test two causal models that attempt to explain the observed pattern of rural densities across south-eastern Australia (n = 414 communities). We distinguish between a “productivist” model—applicable for most of white Australia’s history—and a consumptionist model that takes account of recent counter-urbanisation trends. These models are applied to the entire study area and, in recognition of the study area’s internal heterogeneity, to five clusters of communities. In the drier inland and remoter zones, the productivist model exhibits the greatest explanatory power, while in the more accessible and well-watered “multifunctional” zones, an expanded model that incorporates a measure of “amenity” produces the best results. The research finds that simple environmental factors, coupled with relative location within the national space economy, act as dominant controls over rural population density in early 21st century Australia.

This article presents a historical reprise of 40 years of policy interest in ethnic minority businesses in the UK. It contrasts the pronouncements of policymakers with the reality of ethnic minority entrepreneurship. Such an exercise is surprisingly rare given the activism of policymakers in this arena and growing scholarly interest in this field. Our historical overview is informed by a novel research method that plots references to ethnic minority entrepreneurship in the British Houses of Parliament. Though the UK has been the site of some interesting policy experiments on ethnic minority entrepreneurship, their impact has been slight when set against the context of broader political-economic change.  相似文献
