Longitudinal relations between past suicidality and subsequent changes in psychological distress at follow-up were examined among gay, lesbian, and bisexual (GLB) youths, as were psychosocial factors (e.g., self-esteem, social support, negative social relationships) that might mediate or moderate this relation. Past suicide attempters were found to have higher levels of depressive symptoms, anxious symptoms, and conduct problems at a later time than youths who neither attempted nor ideated. Psychosocial factors failed to mediate this relation. The interaction among past suicidality, social support, and negative relationships was associated with subsequent changes in all 3 psychological distress indicators 6 months later. Specifically, high levels of support (either from family or friends) or negative relationships were found to predict increased psychological distress among those with a history of suicide attempts, but not among youths without a history of suicidality. The findings suggest that GLB youths who attempt suicide continue to have elevated levels of psychological distress long after their attempt and they highlight the importance of social relationships in the youths psychological distress at follow-up.Earlier versions of this paper were presented at the biannual meeting of the European Association for Research on Adolescence, Oxford, UK, September 2002; and, at the annual meeting of the American Public Health Association, San Francisco, CA, November 2003.Associate Professor of Psychology, The City University of New York—The City College and Graduate Center.

This article analyzes the costs and emissions characteristics of methanol vehicles. The cost-effectiveness of methanol—the cost per ton of reactive hydrocarbon emissions reduced—is calculated and compared to the cost-effectiveness of other hydrocarbon reduction strategies. Methanol is found to cost from $33,000 to nearly $60,000 per ton, while several other options are available for under $10,000 per ton. The cost per part-per-million reduction in peak ambient ozone levels is also computed for two cities, Houston and Philadelphia. Despite the greater improvement in ozone in Philadelphia than Houston, methanol is found to be more cost-effective in Houston. This result occurs because Houston's distribution and marketing costs are lower than Philadelphia's. The costs in both cities, however, are far higher than estimates of the benefits from acute health improvements. Finally, the reduction in ozone exposure in Los Angeles is estimated and the costs of the reduction compared with an estimate of acute health benefits. Again, the benefits fall far short of the costs. 相似文献

A visit to a number of small enterprise and income-generation projects supported under the ODA's Joint Funding Scheme in Zimbabwe and Kenya has raised a series of key points which have wider implications for practitioners and donors. The article discusses each point and makes nine ‘recommendations?s for NGOs and donors who support them. While the general benefits of NGOs — such as their relatively low cost, ability to reach the poor, and innovativeness — are affirmed, the article argues that the challenge facing NGOs is to progress further from this base. In particular, it argues that NGOs need to develop more business-like operations, focusing on the most practicable forms of enterprise structure, but without losing their priority of seeking to benefit the poor and other disadvantaged groups. Technology-oriented projects need to ensure that they concentrate on the application of technology in a market context, rather than developing it for its own sake. NGOs with donors need also to strive for a realistic definition of sustainability, to work towards a more credible project-planning process, and to be aware of the dangers of very visible and expensive investment in project transport undermining NGOs' efficiency. 相似文献

Raymond W. Smilor David V. Gibson Christopher M. Avery 《The Journal of Technology Transfer》1989,14(2):11-22
This paper discusses important aspects of technology transfer between MCC (the first R&D consortium to register under the National Cooperative Research Act of 1984) and company-based personnel. An evaluation of established technology-transfer models leads to a discussion of a parallel-processing approach and three important dimensions of the transfer process: mode, initiative, and continuity. Differences between R&D consortia and their member companies are categorized in terms of values and imperatives, networking, time pressure, the universalistic/particularistic nature of research activities, and different evaluation criteria. Generalized managerial implications are presented for R&D consortia. 相似文献

The intention of this paper is to serve in part as a warning to the international community concerned about corruption, to
keep the focus based on the critical analysis of empirically verifiable information. In ways similar to how theorists spoke
about organized crime in the 1960's and 1970's, articles today attempt to refer to corruption as if there were one agreed
upon definition. However, like the concept “organized crime”, the term “corruption” involves diverse processes which have
different meanings within different societies. Corruption (or a focus on corruption), may be the means toward very diverse
ends and each may have a different impact on the society. While in some societies corruption may correctly be seen to be the
“cause” of forms of social disorganization, in other situations corruption may be the “result” of larger changes. Understanding
the processes within a specific context allows one to understand the nature of the corruption. Corruption rhetoric may too
easily become apolitical platform for ranking and evaluating nations as to their worth based on criteria that lose meaning
when applied across jurisdictions.
