"The author...has attempted to measure the effects of population changes upon the costs of health care [in Poland] by applying a simulation model. In this model the total cost of health care is a function of the per capita cost of health care by age, sex, and place of residence (urban, rural) and population structure.... The paper includes...the results concerning population 60 years of age and over." Data are from several official health-related surveys carried out in 1989.  相似文献

Recent trends in the process of stratification   总被引:1,自引:0,他引:1  
Using the 14 annual cross-sections from the General Social Survey, we specify a "basic model" of attainment and describe the year-by-year fluctuations in its parameters. The results are partially consistent with theories describing the gradual growth of universalistic patterns of stratification and mobility. Under a linear model of educational achievement, we find that the direct effects of race are weakening and the returns to class-based advantages are declining in tandem. The contours of the socioeconomic "gender gap" are also changing in important ways, with the male intercept declining at a rapid pace and the female term registering small and insignificant year-by-year gains. At the same time, the returns to experience and schooling are increasing for men, whereas the corresponding returns for women have remained stable over the 15-year period. This pattern of interaction effects implies that the size of the gender gap varies over time and across different population groups.  相似文献

Although survey researchers are often warned against using prestigenames in questions (e.g., identifying Contra aid as "PresidentReagan's policy"), prestige names are still commonly used. Tolearn more about the effects of using prestige names, we analyzetwo sets of experiments—on judicial confirmation electionsand on an initiative on tax indexing. The results indicate thatprestige names do more than shift responses in one direction—they eliminate the effect of education on DKs and provide moreof a political basis for the responses.  相似文献

Using data from the 1976 and 1988 censuses, the author notes that the population of Senegal has grown by 37.6 percent over the period and that this growth is concentrated in urban areas. One feature of this trend has been the growing primacy of the capital Dakar and a decline in the relative importance of smaller towns. The need to discourage rural-urban migration by promoting socioeconomic development in rural areas is stressed. (SUMMARY IN ENG)  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
