The HIV/AIDS epidemic continues to be a leading public health issue in the United States. During the past decade, the epidemic has shifted away from the gay community, although gay and bisexual men continue to be the largest single HIV exposure category. Now, HIV increasingly affects low-income people of colour in urban areas, as well as women. As AIDS becomes more and more a minority, inner-city disease, public focus on the epidemic as a significant social and political issue is waning. While a full survey of current issues in US law is beyond the scope of this article, the focus here is on current issues that are highly relevant to the direction the epidemic appears to be taking.  相似文献

Managed care entities face numerous liability issues in today's changing healthcare environment. This Article provides the plaintiff with a comprehensive road map for navigating the many avenues of managed care liability. The author describes ERISA pre-emption provisions and suggests ways plaintiffs' attorneys can strive to narrow the pre-emption. The Article also provides in-depth analysis of each theory of managed care liability that has been litigated against managed care entities to date, and then goes on to explore state laws imposing liability on managed care entities, and how HMO liability is being reformed through legislative action. For plaintiffs' attorneys seeking the full spectrum of theories of managed care liability, or for defendants' attorneys wanting to remain updated on all potential claims to defend, this Article constitutes an extensive primer on the current issues.  相似文献

A group of 29 college students who had been arrested or nominated as having participated in a street disturbance aimed at producing social change were interviewed. The interview schedule was highly similar to one which had been used to investigate attitudes toward violence in a random, representative sample of American men. The data collected from the arrestees are compared with data from college students in the national sample. This study shows that the arrestees are more likely to think that violence is necessary to produce social change than are college students generally, and are more likely to believe that existing social institutions are inadequate. As a group, the arrestees are more identified with white student demonstrators and black protestors than are college students generally. The arrestees are also likely to regard the police as untrusworthy, looking for trouble, and apt to dislike people like themselves. In addition to the negative attitudes toward the police held by the student arrestees, they are more likely to regard police actions as violence (and hence provocative) than are other college students. The arrestees are far more likely than other college students to cleave to humanistic values. However, most of the differences between the arrestees and other American college students could be predicted from a general model of the justification of violence, so that it appears that the student activists' beliefs differ not so much in kind from those of other Americans as they do in degree.This research was funded by NSF Grants GS 2424 and GS 28295 under a project codirected by Monica D. Blumenthal, Robert L. Kahn, and Frank M.

Pregnancy among adolescents, and especially among low-income adolescents, represents a high-risk situation from multiple points of view. When compared to data for the population at large, obstetrical outcome is worsened, subsequent educational attainment is poor, social prognosis is guarded, and repeat unwanted pregnancies are common. The surviving infants, similarly have relatively high incidences of medical and developmental problems. In recent years, comprehensive interdisciplinary programs have been organized to offer more meaningful help to these individuals. The present report describes the authors' 5-year experience with one early intensive program. Considerable medical, educational, and social successes have been noted. The results are especially striking when contrasted with the authors' current experience with an improving but still more fragmented and less successful program. Findings concerning infant development and the mother-infant interaction are also noted. Finally, issues related to the achievement of successes and the persistence of problems after provision of more adequate comprehensive services are discussed.This study was supported in part by Grant No. 03-H-000-079-03-0, Maternal and Child Health Service, H.S.M.H.A., H.E.W.While on the faculty of the State University of New York, College of Medicine at Syracuse, was a founder and the first medical director of the YMED program.Specialty is Developmental Psychology, and research interests concern infant and early child development and the effects of children on parents. While on the faculty of Cornell University, served as a consultant to the YMED program.Project director of the high-risk program.While on the faculty of the State University of New York, College of Medicine at Syracuse, was obstetrical director of the YMED program.  相似文献
