Recent research on the impact of labor migration on the socioeconomic development of developing countries has provided opportunity to try and resolve some of the long-standing polemics that have pervaded the literature on migration and development. This article focuses on findings concerning the labor, remittance, and social impacts of emigration on countries that have participated in labor emigration. While a great deal more research needs to be done, recent findings confirm that in some situations the sort-term impacts of labor migration on sending countries have been considerable.  相似文献

Demographics: people and markets   总被引:1,自引:0,他引:1  
The basics of demography are now basic to us business as well. Demographics combine demographic data with socioeconomic and geographic factors to help business and other managers know the market for their goods and services. This pamphlet explains market, product, and site analyses, discusses data sources and resources, and includes case studies involving major corporations. Post-war population trends have had an enormous impact on consumer and labor markets, bringing home to business the importance of taking advantage of demographic shifts. Advances in computerized access to data describing changes and increased consciousness of their economic significance has spurred the application of demographic knowledge by managers and the growth of the demographics information industry. The pamphlet describes the resources and methods of demographics including the creation and use of demographic data products.  相似文献

"Net undercount rates in the U.S. decennial census have been steadily declining over the last several censuses. Differential undercounts among race groups and geographic areas, however, appear to persist. In the following, we examine and compare several methodologies for providing small area estimates of census coverage by constructing artificial populations. Measures of performance are also introduced to assess the various small area estimates. Synthetic estimation in combination with regression modelling provide the best results over the methods considered. Sampling error effects are also simulated. The results form the basis for determining coverage evaluation survey small area estimates of the 1900 decennial census."  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

Pharmaceuticals traditionally have been viewed as a cost-effective component in medicine's technological armamentarium. The use of pharmaceuticals has been estimated to account for 6-8 percent of the nation's total expenditures on health care. The first wave of pharmaceuticals/biologicals that has been produced by the biotechnology industry has offered therapies that can provide much benefit to patients, but it has also raised concern about the cost of these new recombinant drugs. In addition to pricing, methods of promotion and modifications in the FDA approval process have raised concerns.  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
