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

Doctors are not health care providers, and medicine is not a commodity. To practice medicine well, the doctor must attend to each patient as a whole person and be faithful in giving care when cure is not possible.  相似文献

The problems that people experience in social roles can be regarded as either causes or consequences of psychological symptoms. To reflect one of these possibilities, Pearlin et al. (1981) developed measures of "role strains" which are considered sources of psychopathology. To reflect the other position, Dohrenwend et al. (1981) constructed measures of "role functioning" which are seen as consequences of psychopathology. We show that the measures developed by these two teams of investigators are similar in content and show substantial empirical overlap despite the different meanings attributed to them. In an effort to understand whether these highly correlated measures assess, "role strain" or "role functioning," we conduct an exploratory analysis of marital and housework role problems, using a small panel sample of New York City residents. Specifically, we use instrumental variables to identify reciprocal effects between psychological distress and each role area. We find that the relationship between housework role problems and distress is more consistent with Pearlin et al.'s interpretation, whereas the relationship between marital problems and distress is more consistent with that of Dohrenwend et al. Investigators interested in measuring either role strain or role functioning must bear in mind the strong possibility of contamination from the other construct.  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

The United States is now engaged in a momentous national debate about health care. How can we provide the best care possible while simultaneously containing cost (to promote the general economic integrity of society) and somehow maintain a semblance of a free health care marketplace. This is not just a political question; it is also a question of ethics. It is an ethical consideration because the current debate is not just about designing or promoting health care systems that can best address our concerns for costs, quality, and accessibility. It appears that at least some participants in the debate would not stop at arguing their beliefs as valid; they would make their beliefs law. Some urge the creation of the right to health care as a matter of law. There are significant differences between beliefs and rights, however, and they need to be considered carefully in the ongoing debate over the future of this country's health care delivery and financing system.  相似文献
