The author notes that questions on housing will be included for the first time. Other topics considered include reliability of data, confidentiality, and organization.  相似文献

Social workers are required to collect a considerable amount of personal information about clients and their families which may be unrelated to direct clinical work. Administrators often use this for the purpose of payment, service documentation, agency planning, and accountability. The worker's concern about the appropriateness of collecting this data may result in poor compliance or even falsification of information. In a survey of Minnesota social workers, noncompliance with data collection requirements was substantial. The authors also found a significant degree of conflict about privacy and confidentiality issues. These findings suggest a basis of concern for those who must rely on accurate data for administrative planning.  相似文献

The author argues that the burden of proof for the safety and efficacy of some medical devices properly lies with the manufacturers of the devices and with the providers who use them. The controversy over breast implants is used as a case for this shift in the burden of proof of safety and effectiveness.  相似文献

College newspapers are a powerful but underutilized medium for educating students on health issues, including those related to drug and alcohol use on campus. Editors of these publications are in a position to wield significant influence among their readers. In addition to communicating factual information about the prevalence and impact of substance use among college students, editors can use the press to advocate changes in students' attitudes and behaviors and in college or community policies that affect substance use. A pilot conference was held to help New England college newspaper editors perceive the importance of their role in educating their peers about substance use and other health-related issues, and to offer concrete suggestions as to how they can incorporate these topics into an "activist" campus press.  相似文献

"This article shows that an analysis of the impacts of immigration [in Western Europe] has to be divided into allocational and distributional aspects. From an allocational point of view, like free trade in goods, services and capital, migration is welfare-improving as long as marginal productivities of labor are not equalized worldwide. From a distributional point of view, however, the immigration society has to bear the effects of sharing its common public goods and its social values with the new immigrants. Free immigration will only be allowed if the allocational welfare gains exceed the distributional welfare losses. According to this rule of thumb, a guideline for an efficient migration policy is sketched."  相似文献

Demographic trends in rural areas of the former Soviet Union are analyzed over the 10-year period 1979-1989, using census data. Over the whole country, the rural population decreased by 1 percent, while the urban population increased by 15 percent, although significant differences existed between the European and Central Asian republics. Factors affecting the dynamics of rural populations are analyzed, including the undeveloped social and economic infrastructure in rural areas.  相似文献

The application of the subjective variable to research on attitudes toward fertility in Poland is considered. The variable concerns the determination of ideal family size and attitudes toward having more children. The author shows how an ex post facto variable was constructed, describing positive, negative, and neutral feelings toward fertility during the course of a study on attitudes toward procreation.  相似文献
