This paper is an historical analysis of foster care, exploring its linkage with the concept of permanency in the United States (a major force in defining the direction of foster care policy) and in Australia. Use of the political economy and feminist approaches highlights the extent to which the child welfare system is based on policies which enhance social inequality, while promoting a particular ideal of the nuclear family which dichotomises mothers as good or bad. 相似文献

Whereas the expected problems of population aging are discussed extensively in the mass media, with a strong emphasis on the costs of pensions and care in the future, philosophy has remained virtually silent about the many aspects of aging and gerontology relevant to the discipline. However, aging is not a new topic in philosophy; it only has to be reintroduced. Although the three authors offer different perspectives on aging, there is a common effort to reinterpret the fundamental experience of finitude in the light of aging. 相似文献

Long-term effects of teaching behavioral strategies for managing persistent auditory hallucinations in schizophrenia 总被引:4,自引:0,他引:4

1. Attendance at a 10-week class designed to teach behavioral management strategies to people with schizophrenia was effective in reducing some of the negative characteristics of auditory hallucinations for 12 months and in reducing anxiety for 9 months after completion of the class. 2. The sustained improvement experienced by class participants was characterized by their voices being less frequent and more mumbled and the participants feeling more in control, less distractible, and less anxious. 3. Participants recommended that other mental health consumers take similar classes to learn how to better manage their voices. 4. Monthly support groups may help participants maintain gains lost during the follow-up period. 相似文献

It has been demonstrated for many pre-industrial populations that the age at marriage, or marriage duration, influences age-specific marital fertility but the reason for this remains unclear. Among the several mechanisms that may be responsible, the following are often cited: secondary sterility or increased subfecundity associated with parity; declining coital frequency; the age difference between the spouses; and, importantly, parity-dependent fertility control. If the latter mechanism were partly responsible for the marriage-duration effect in pre-transition populations, it would contradict the concept of the modern fertility transition as the evolution (or revolution) from parity-independent to parity-dependent fertility. The study presented in this paper investigates the relative importance of these alternative explanations. The application of multivariate Poisson regression to the fertility data from two birth cohorts in the Belgian city of Leuven shows that a linearly declining or even concave age-specific fertility pattern, disaggregated by age at marriage, does not imply parity-dependent fertility limitation. 相似文献

Following a comprehensive evaluation of the health risks of radon, the U.S. National Research Council (US-NRC) concluded that the radon inside the homes of U.S. residents is an important cause of lung cancer. To assess lung cancer risks associated with radon exposure in Canadian homes, we apply the new (US-NRC) techniques, tailoring assumptions to the Canadian context. A two-dimensional uncertainty analysis is used to provide both population-based (population attributable risk, PAR; excess lifetime risk ratio, ELRR; and life-years lost, LYL) and individual-based (ELRR and LYL) estimates. Our primary results obtained for the Canadian population reveal mean estimates for ELRR, PAR, and LYL are 0.08, 8%, and 0.10 years, respectively. Results are also available and stratified by smoking status (ever versus never). Conveniently, the three indices (ELRR, PAR, and LYL) reveal similar output uncertainty (geometric standard deviation, GSD approximately 1.3), and in the case of ELRR and LYL, comparable variability and uncertainty combined (GSD approximately 4.2). Simplifying relationships are identified between ELRR, LYL, PAR, and the age-specific excess rate ratio (ERR), which suggest a way to scale results from one population to another. This insight is applied in scaling our baseline results to obtain gender-specific estimates, as well as in simplifying and illuminating sensitivity analysis. 相似文献

Using conjoint analysis the sensitivity for the four most important retail attributes: price, quality, assortment and locational convinience for food stores is measured for a sample of 400 consumers in Tilburg, The Netherlands. In a second wave the actual shopping behavior is measured using a self-administrated questionnaire. The sensitivity scores are used separately and in conjunction, as sensitivity patterns, to explain patterns of shopping behavior as well as separate shopping characteristics. The relationships found, suggest the usefulness of this kind of approach as it gives in-depth insight into shopping behavior and choice of grocery store. 相似文献

This article examines recent trends in nonmarital cohabitation in the Nordic countries. The data from the Nordic countries suggest that nonmarital cohabitation has moved from being a deviant phenomenon to an institutionalized pattern of entering family life. 相似文献
