Few studies have examined the effects of early life conditions on the timing of the onset of heart disease. We use the remarkable example of a representative sample of the population of older Puerto Ricans aged 60– 74 who lived in the countryside during childhood (n = 1,438) to examine the effects of seasonal exposures to poor nutrition and infectious diseases during late gestation on the timing of the onset and the probability of ever experiencing adult heart disease. Cox and log logistic hazard models controlling for childhood conditions (self-reported childhood health status and socioeconomic status [SES], rheumatic fever, and knee height) and adult risk factors (adult SES, obesity, smoking, texercise, and self-reported diabetes) showed that the risk of onset of heart disease was 65% higher among those born during high-exposure periods compared with unexposed individuals. However, there were no significant differences in median time of onset for those ever experiencing heart disease. As a comparison, we found that there were no significant seasonality effects for those who lived in urban areas during childhood. We conclude that early exposures in utero have important ramifications for adult heart disease among the older Puerto Rican population. We show, however, that while exposure is associated with the probability of ever experiencing adult heart disease, it is not associated with the timing of onset among those who do experience it.  相似文献

The Japanese system of school–work has been widely admired for the strong communication and recruitment relationships that exist between high schools and employers. We develop a framework for understanding the macro-level conditions that fostered the effectiveness of the system up until the early 1990s. These conditions included a stratified secondary educational system, a large supply of high-quality high school graduates, and high demand for young workers to fill entry-level positions in the internal labor markets of large firms. We use original data from a sample of urban high schools to analyze how Japanese employers’ recruitment patterns changed in the 1990s and beyond. The results of that analysis and a counterfactual analysis suggest that recent changes, especially in Japanese employment institutions, have significantly weakened high school–employer relationships. We suggest implications of the Japanese case for school–work processes in other postindustrial societies.  相似文献

Using behavioral self-regulation processes may facilitate exercise among older women with heart disease. Data from women in a heart disease-management program (n = 658, mean 73 years), was used to explore associations among exercise self-regulation components (i.e., choosing to improve exercise and observing, judging, and reacting to one's behavior) and exercise capacity. General linear models showed that choosing exercise predicted higher exercise self-regulation scores postprogram and 8 months later. In turn, these scores predicted greater improvements in exercise capacity concurrently and 8 months later. Interaction analyses revealed that the effect of self-regulation on exercise capacity was stronger among women who chose to work on exercise.  相似文献

Evidence-based practice (EBP) is upheld as best practice in health and human services but there is a need for more research on how this approach can be enabled in day-to-day practice. This qualitative study examined EBP with allied health managers and practitioners in a health service network (n = 17). The findings highlight the systemic nature of EBP and the extent to which it involves both individual and environmental attributes. Individual attributes include clear understanding of EBP, relevant knowledge and skills, and motivation and passion. Environmental attributes are the presence of an organisational culture that values and prioritises EBP and an integrated mix of research support services, professional development activities, supervision and mentorship, and university partnerships. Theoretical frameworks can be useful for making sense of complex processes, planning, and evaluating change. Therefore, the findings are presented as a framework incorporating reflective questions relating to the elements identified as enabling EBP.  相似文献

This paper reports the results of a quantitative 42-item survey that explored foster, adoptive, and kinship parents’ (N = 160) utilization of different types of respite services (formal, informal, and a mixture of formal and informal), as well as their impressions of the impact of respite care on aspects of their lives related to family cohesion and stability, caring for their children, and their personal wellbeing. An exploratory cross-sectional, survey design was used to assess both the formal and informal respite care experiences of the foster, adoptive, and kinship caregivers. Two-tailed Fisher’s exact tests were used to examine the relationship between the type of respite received and caregivers’ respite experiences. Findings indicated that parent experiences differed depending on the type of respite services they received. Specifically, parents who used a mixture of formal and informal respite reported positive experiences related to respite more frequently than the other two types of respite groups, while those who received only informal respite reported less benefit than others. Parents who used formal respite (either alone or mixed with informal respite) reported greater stress reduction. The greatest increase in family stability was reported by parents who received a mix of informal and formal respite. While this study revealed clear benefits for families to using both informal and formal respite services, the findings suggest that formal respite care was helpful to parents regardless of whether used alone or in combination with informal care.  相似文献

In many countries today, digital technology and instant communication are embedded in children's everyday lives to the extent that their play frequently incorporates smartphones, the Internet and other technologies. In this paper, we explore the recent historical conditions within the New Zealand context that have increased the accessibility of these technologies and imbued them with particular meanings. We suggest that from a Foucauldian perspective, these technologies can be seen as a form of subtle disciplinary power using techniques of governmentality through which children's ways of thinking are shaped to benefit societal requirements of the current historical era.  相似文献

Modeling the dependence between uncertainties in decision and risk analyses is an important part of the problem structuring process. We focus on situations where correlated uncertainties are discrete, and extend the concept of the copula‐based approach for modeling correlated continuous uncertainties to the representation of correlated discrete uncertainties. This approach reduces the required number of probability assessments significantly compared to approaches requiring direct estimates of conditional probabilities. It also allows the use of multiple dependence measures, including product moment correlation, rank order correlation and tail dependence, and parametric families of copulas such as normal copulas, t‐copulas, and Archimedean copulas. This approach can be extended to model the dependence between discrete and continuous uncertainties in the same event tree.  相似文献

In this article, we discuss the theoretical implications of empirical elaborations of Bernstein’s (1997) model of identity deployment. New research encompasses a diverse array of venues and targets and elaborates on the mechanisms through which identities may be deployed strategically. Application of the identity deployment model spans a variety of so‐called ‘identity movements’ as well as ethnic, nationalist and indigenous movements, and community mobilization. Identity deployment is also a useful strategy in organizational and professional contexts, as in the micro‐brewery movement or culinary movements, demonstrating the theoretical generalizability of the original model. New research closely examines the relationship between identity and strategy and the conditions that affect activists’ choice of identity strategies as well as the situations where they might avoid identity strategies altogether. Research finds that identities may be deployed performatively, rhetorically or discursively. Identity deployment may be facilitated by emotional displays, music and ritual. The way that power and authority are organized in a given venue determines in part the capacity of activists and organizations to alternate between celebrating and suppressing difference from the majority. Identity deployment influences internal and external outcomes, affecting mobilization and goal achievement. Finally, feedback loops link the different analytic dimensions of identity.  相似文献
