This article details the clinical foundations of a social work focused community-based participatory research project promoting women’s mental health during and around the time of pregnancy. Specifically, we discuss the theoretical, empirical and organizational implementation of an enhanced engagement model of mental health service delivery that integrates evidenced based practices into the structure and services of an existing non-profit maternal and child health home visiting agency. The model is grounded in literature addressing barriers to accessing mental health care among minority women living in low-income communities. We discuss informing the intervention through direct consumer involvement, as well the rationale supporting the inclusion of Interpersonal Psychotherapy and Cognitive Behavioral Therapy into the design and implementation of the model which emphasizes adequate training of staff with varying levels of mental health experience. Finally, we describe typical client situations and responses reflected by the Enhanced Engagement model and discuss future implications of this approach as a way to offer meaningful intervention to women and families who may not have access or eligibility to utilize specialty mental health services.  相似文献

Survival models are widely used in demography to analyse the timing of events such as death or leaving school. However, for events such as marriage or childbirth that are not experienced by everyone, standard survival analysis conflates the speed of progressing to an event with the proportion that never experience the event. The problem can be overcome by applying a ‘split population’ or ‘cure’ survival time model which splits the population into those who eventually experience the event and those who do not, and determines the speed of progression for the former. This paper demonstrates the use of split-population models in examining variables which affect the propensity and timing of additional births. The data analysed are from a sample of women from the 2001 Household, Income and Labour Dynamics in Australia (HILDA) Survey (N = 4,611). We model the propensity and time to have another child given sex composition of existing children, number of siblings and age at first birth for three cohorts of women. The study finds evidence of a preference for a mixed-sex composition, and an increased propensity for women with two boys to try for a third child. Women in later cohorts tend to have more children if they themselves come from larger families. Age at first birth is strongly associated with the propensity to have another child and with the speed of progression.  相似文献

The standard dual‐self model of self‐control, with a shorter‐run self who cares only about the current period, is excessively sensitive to the timing of decisions and to the interpolation of additional “no‐action” time periods in between the dates when decisions are made. We show that when the shorter‐run self is not completely myopic, this excess sensitivity goes away. To accommodate the combination of short time periods and convex costs of self‐control, we introduce a cognitive resource variable that tracks how the control cost depends on the self‐control that has been used in the recent past. We consider models with both linear and convex control costs, illustrating the theory through a series of examples. We examine when opportunities to consume will be avoided or delayed, and we consider the way in which the marginal interest declines with delay.  相似文献

作为美国环保局工业废水中微量汞的分析方法,1631E在水质监管中的应用普及率近年来不断增长,基于这种分析方法,人们发展了多种汞测试仪,并用于满足质量控制的要求。尽管最初设计是从样品中直接冲洗汞,但目前几乎所有基于1631E的痕量水银分析仪都采用了连续流动分析技术。本文介绍了一款采用美国环保局1631E方法的自动化直接冲洗汞的痕量汞分析仪。  相似文献

The author sets forth a method for adjusting age distributions to eliminate the effects of digit preference and seeks to overcome a bias present in an approach developed by Zelnik in 1961. Census age pyramids are derived for Bangladesh, Libya, and the Australian aborigines for the years 1974, 1973, and 1981, respectively.  相似文献

Data from the 1991 Census largely confirm earlier projections of the size and structure of the Aboriginal population, although the data for Torres Strait Islanders are markedly inconsistent with previous counts. The 1986 and 1991 Censuses mark the first intercensal period for decades for which Aboriginal population counts have been consistent. This provides an opportunity, taken in this paper, to examine closely the discrepancies between projections and the 1991 Census and to comment on ways in which determinants of Aboriginal population change are diverging from the parameters used for previous projections. We pay particular attention to mortality prospects, because of the occurrence in the 1991 Census of a higher than expected sex ratio and differences between projections and counts for certain age groups. We note the evidence for under-enumeration of the Aboriginal population in particular age groups in the 1991 Census as in previous censuses, and estimate the size of adjustments necessary to correct for some, but not all, of these deficiencies. The analysis shows that Aboriginal fertility increased in the second half of the 1980s.  相似文献

Objectives. Although the Fetcher Bill Hypothesis, which is that legislators introduce bills in order to extort campaign contributions from organized interests, has been given new prominence by suggestions that it can provide a general explanation of the composition of legislative agendas and the structure of interest communities, tests of the hypothesis are narrow, rare, and indirect. We provide an alternative test to more directly assesses its core implications. Methods. We test the hypothesis using single‐year and pooled‐regression analyses of 1995, 1997, and 1999 data on lobby registrations by organized interests in the American states—a venue providing substantial variation in legislative activity, the density of lobbying organizations, and the campaign finance systems that are presumed to drive rent seeking. Results. The tests provide little evidence that policy agendas induce lobby registrations. Conclusions. These results indicate that the Fetcher Bill Hypothesis cannot provide a sufficient account of the composition of either legislative agendas or lobbying communities.  相似文献

The rising cost of health care in Western European countries is now seen by many governments as a problem, and attempts are being made to find a solution by introducing cost-containment policies.
The author begins by reviewing trends in health care expenditures, and examines some of the underlying reasons for the upward trend.
He then considers some of the more important differences in the organization and financing of Western European health care systems, before surveying the different kinds of cost-containment policies which are being, and could be, pursued.
The conclusion is that present cost-containment policies do not take sufficiently into account the underlying reasons for rising costs, and that the criteria for evaluating the success of these policies are inadequate. To be successful, the policies will have to be altered, and the objectives and means of evaluation reconsidered.  相似文献

As one of the world's most traded commodities, coffee has been criticized for its contribution to environmental degradation, social injustice, and economic disparities between the producing regions of the Global South and consuming countries of the Global North. However, the Fair Trade concept is promising to change this through the establishment of a trading system where producers, importers, and processors form a more direct network characterized by an established set of ethical principles and practices deemed as “fair.” While the transformational benefits of Fair Trade at the producer level have been examined in several impact studies, the farmers' low awareness and understanding of Fair Trade concepts, principles, markets, and customers represent an issue of concern. Among the many benefits associated with increased Fair Trade awareness is greater participation in Fair Trade governance bodies and the long‐term viability of the market itself. This research looks at Fair Trade from the perspective of farmers and their cooperative and uses the case of Cooperativa Agraria Cafetalera Pangoa, Peru, to examine how Fair Trade awareness (defined as knowledge of different areas of Fair Trade) is understood at the producer level. We then develop a three‐level Fair Trade awareness Model that illustrates both the existing and desired levels of understanding with regard to Fair Trade awareness.  相似文献
