Individuals with severe mental illness (SMI) are at risk for HIV/AIDS. Despite the availability of supportive community programs for those with SMI, there have been no published evaluations of community-level HIV prevention trials among this population. A pilot intervention trial was conducted to determine the feasibility of such an intervention in supportive housing programs (SHPs). A multi-component community-level trial was implemented in two SHPs with a total of 28 residents. Participants completed assessments at three time points: prior to the intervention (baseline), following skills training (post-assessment), and following the 4-month community intervention (follow- up). Results demonstrated significant improvements in psychosocial risk factors at both post- and follow-up assessments, with indications of sexual behavior change at follow-up. The community-level intervention appeared to reduce the risk of HIV among persons with SMI living in SHPs, and supports the importance of conducting larger scale intervention trials.  相似文献

Abstract

In a segment of his recent television series on economics, “The Age of Uncertainty,” John Kenneth Galbraith makes a number of critical remarks about multinational corporations. However, towards the end of the program, the screen is suddenly filled with pictures of bustling Singapore, and Galbraith comments that, whatever else can be said of them, the MNCs have played a major role in bringing economic development and employment to this and many other parts of the world. The implication is that the employment and economic growth fostered by the large corporations in Asian countries like Singapore are—by definition—changes for the better.  相似文献

State policy makers are concerned about costs of past policies whose benefits are often difficult to determine. Some have recommended a strategic approach to state economic policy making in order to eliminate ad hoc incentives. Lessons derived from the literature on state enterprise zones are used to assess the 1993 Federal Empowerment Zone and Enterprise Community initiative. States can expand policy alternatives by fostering the growth of a marketplace of economic development ideas at the local level. Strategic plans should focus on development of competing, bottom-up solutions, rather than packages of specific incentives.  相似文献

The general equilibrium framework developed in this paper for analyzing the limits to rent-seeking waste goes beyond the existing literature by incorporating tax-financed, public subsidies and rent-protecting activities into a rent-seeking environment. We show that the limits to rent-seeking waste depend on the extent to which government subsidizes rent seekers and rent defenders through tax-financed grants, contracts and favors. As observed by Tullock (1967), the diversion of resources toward efforts to acquire a monopoly rent causes a social waste in addition to the excess burden of monopoly pricing measured by the Harberger triangle. In the absence of government subsidies to rent-seeking and under competitive conditions, this additional waste cannot exceed the maximum monopoly rent attainable. However, if government subsidizes expenditures on rent-seeking, then the additional waste can exceed the Tullock rectangle of monopoly rent and, in the limit, equal the economy's maximum potential social surplus.Rent avoidance expenditures reduce the rent to be captured and thus discourage rent-seeking. If rent avoidance is a relatively efficient mechanism for transferring consumer surplus to rent granters, then rent-seeking expenditures are displaced by less wasteful expenditures on rent defending. As a result, under competitive conditions, unsubsidized demand for private rent protection may be socially efficient. Nonetheless, the upper limit to rent-seeking waste depends on constitutionally determined maximum rates of public subsidies to rent-seeking and rent-avoidance activities.  相似文献

Morphological changes of the pubic symphysis provide an important means of estimating age at death in the adult skeleton. Today, the most widely used method of symphysial aging is the three-component system devised by McKern and Stewart for males and modified by Gilbert and McKern for females. Examination of the published data for both sexes reveals that the relationship of total symphysial score with predicted age and observed standard deviations can be expressed by a set of simple linear and polynomial equations. This approach is more statistically efficient since it uses the total data base rather then independently treated data subsets in predicting age from total symphysial score. It has the added advantage of providing a simple method of predicting symphysial age on small computers or programmable calculators.  相似文献

Although reports state the frequency of general crime has fallen across the developed world, no such trend is evident within organised crime. This has caused law enforcement agencies to search for more innovative approaches to tackle this global problem. Emerging prominently within this period has been a ‘disruption’ approach, albeit little systematic research currently supports its use. This study explores the way one English Police Force has tackled 15 Organised Crime Groups (99 individuals), using this type of approach. The study specifically examines the characteristics of the offender, the tactics used, and the re-offending levels following the police activity. It concludes by highlighting: the methodological challenges associated with the measurement of organised crime disruption; the ethical questions surrounding this type of intervention; and the overall effectiveness of the approach.  相似文献

Abstract

Investigative interviews with children about alleged abuse were analysed to determine the degree to which the child's responses adhered to a story grammar framework, and whether the presence of story grammar elements was associated with interviewers’ adherence to best-practice (i.e. open-ended) questioning. The sample included 51 interviews with child witnesses from across Australia. The interviews were administered by a police officer with children (37 girls and 14 boys) aged 316 years (M age = 103.82 months, SD = 34.21 months). The interviewers’ questions were categorised as open-ended or specific and the children's responses were classified as a story grammar element, context/background information, or ‘don't know’ responses. The majority of interviewer questions were specific in nature and the majority of children's responses were context/background details. Open-ended questions were more successful in eliciting story grammar from children. Of the story grammar elements, the interviewers’ specific questions usually targeted setting and attempt details. These findings suggest that improvement in the narrative coherence of children's reports of abusive events can potentially be achieved by increasing interviewers’ use of open-ended questions.  相似文献
