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

The social policy of the Thatcher government is characterized by an abrupt shift in the direction of the private sector. To what extent does this reflect what people want? The Institute of Economic Affairs conclude from the only suitable national opinion survey that such a move is strongly supported. Our reanalysis of their data shows that this strand in public opinion can coexist with, and need not contradict, an equal public enthusiasm for state welfare. Such results have important implications for our understanding of social policy. We conclude, therefore, with a discussion of contrasting marxist and liberal accounts which seeks to show that the evidence of ambivalence in popular attitudes about the welfare state supports particular developments in theory. 相似文献

Though ubiquitously used for evaluating university counseling services, client satisfaction assessment has been hampered by inadequate instrumentation. Systematic use of a short form of the Client Satisfaction Questionnaire (CSQ) in one such center over the past 5 years is described, together with strategies to ensure maximal accuracy and utilization of results. Several method factors were investigated. Optional respondent identification was not found to reduce response rate or increase reported satisfaction compared to anonymity, while a substudy obtaining very high response suggested bias from nonresponse to the routine survey (response rate = 40%) was not great. The CSQ was found to have excellent psychometric properties and many advantages for use in student service settings. Relationships between satisfaction and a number of other variables such as demographics, precounseling expectancies, problem type and severity, counselor differences, and duration of counseling are reported. Ways such findings were incorporated in service planning are briefly discussed. 相似文献

Recent patterns of Hispanic immigration to the United States are examined using data from the U.S. Immigration and Naturalization Service. "From 1960 to 1978 Hispanic immigration increased significantly, reflecting the general acceleration in total immigration to the United States. Demographic trends reveal that Hispanic immigrants are increasingly working-age women. Their occupation composition is primarily blue collar, with operatives emerging as the predominant job category during the 1970s." The authors note that these immigrants settle primarily in a small number of urban centers of Hispanic population and culture in the United States, and thus the effects of immigration will be concentrated on the low-skill segment of particular urban labor markets that already contain large numbers of Hispanic workers. 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

The impact of immigration on unemployment in Canada is examined for the period 1983-1985. The authors attempt to construct a balance sheet of immigration in terms of labor supply and demand. They conclude that immigrants create more jobs than they fill, and that their net effect on the employment situation is positive. (SUMMARY IN FRE AND SPA) 相似文献

The UN High Commissioner for Refugees (UNHCR) commissioned researchers from the University of Zambia to conduct a socioeconomic survey and census of "spontaneously settled" Zairean and Angolan refugees in the Northwestern Province of Zambia in 1982. The sample consisted of 188 Angolans, 201 Zaireans, and 2 South Africans. The difficulties experienced by refugees in Northwestern Province in achieving integration were related to a combination of factors including the lack of a clear national policy on refugees and refugee status, a national concern for maintaining security, the popular belief that aliens are responsible for an increasing crime rate, the desire by immigration officials for stricter laws to control alien infiltration, conflict between traditional and modern leaders, and Zambia's deteriorating economic situation. In spite of the problems described, the integration of refugees into existing communities is a desirable goal and should be encouraged. One should not assume that self-settling refugees are able to live with ethnic kin, receive assistance and hospitality, and thus are better off than those in camps. The Zambian case provides ample evidence that integration is not easy even with kin support, shared ethnicity, language, and historical connections. Moreover, given the fact that Zambia will continue to receive refugees it is vital that there is a well defined refugee policy and an administrative mechanism for implementing that policy at all levels. This will be particularly important in Zambia as it will undoubtedly continue to receive large influxes of refugees, from countries such as Namibia, Uganda, Angola, Mozambique, and South Africa. 相似文献

"Although the flow of human beings between countries and continents has marked the behaviours of populations for centuries, present international migration is clearly characterized by a number of new factors which make it distinct from international movements of people in the past. This paper aims to identify such new factors relating to the underlying reasons for the international mobility of people, including the motivations of the individuals concerned, and attempts to examine the consequences as they are being faced by the individuals involved, the countries concerned and--in more general terms--the international community."
