Now that evaluators have been sensitized to the importance of moral and ethical issues in their work, it is time to move beyond generalities and examine the moral and ethical implications of specific evaluation models in specific settings. This paper proposes a framework that can be used to examine moral and ethical dimensions of evaluation and illustrates it by analyzing a selected model of mental health evaluation. Such a systematic identification of moral issues can improve evaluation practice both proactively, by shaping the training of evaluators, and retrospectively, by contributing to meta-evaluation.  相似文献

During the past decade, the international statistical community has made several efforts to develop standards for the definition, collection and publication of statistics on international migration. This article surveys the history of official initiatives to standardize international migration statistics by reviewing the recommendations of the International Statistical Institute, International Labor Organization, and the UN, and reports a recently proposed agenda for moving toward comparability among national statistical systems. Heightening awareness of the benefits of exchange and creating motivation to implement international standards requires a 3-pronged effort from the international statistical community. 1st, it is essential to continue discussion about the significance of improvement, specifically standardization, of international migration statistics. The move from theory to practice in this area requires ongoing focus by migration statisticians so that conformity to international standards itself becomes a criterion by which national statistical practices are examined and assessed. 2nd, the countries should be provided with technical documentation to support and facilitate the implementation of the recommended statistical systems. Documentation should be developed with an understanding that conformity to international standards for migration and travel statistics must be achieved within existing national statistical programs. 3rd, the call for statistical research in this area requires more efforts by the community of migration statisticians, beginning with the mobilization of bilateral and multilateral resources to undertake the preceding list of activities.  相似文献

This article examines four issues that need to be explored by the therapist as possible causes of stress for a male couple: stereotypic male roles, stereotypic sexual roles, homophobia, which includes the "coming out" process, and sexual dysfunctions. These issues can cause anxiety and stress, which may in turn cause relationship problems for a male couple. The role of the therapist is clarified and suggestions for treatment are given.  相似文献

Information about board-and-care homes reported in the media and in federal committee hearings indicates that they are shoddy and exploitative environments that do not provide adequate care. Research done in board-and-care homes in recent years, however, demonstrates that they can provide adequate care and a satisfying environment for some of the people they serve. Policy at the federal, state, and local levels should be guided by both the need to assure the health and safety of board-and-care residents and the needs of residents and operators identified in scientific studies.  相似文献

"This study attempts to explain similarities and differences in the mortality experience of three population groups: Puerto Ricans on the island commonwealth, Puerto Rican born persons in New York City and Puerto Rican born persons in the rest of mainland United States. Mortality is much higher among Puerto Ricans in New York City than among those residing elsewhere. Much of the difference is due to excess mortality caused by cirrhosis of the liver and homicide. Puerto Rican born persons living on the mainland but outside New York City generally have low mortality, even when compared with U.S. whites."  相似文献

Originally presented to the Society of Home Health Care Management of the American College of Physician Executives at its November 16, 1993, meeting in Tucson, Ariz., the program described in this article was the winner of the College's 1994 Innovations Award in Medical Quality Management, sponsored by Merck Sharp & Dohme. The program shows the potential of case management for both improvement in the quality of care and containment of costs for a managed care population with a substantial Medicaid segment. This article is part of a continuing series on innovative programs in home health care.  相似文献
