Ames K  Wilson L  Sawhill R  Glick D  King P 《Newsweek》1991,118(9):40-41
When dying is all that awaits them, more and more people are choosing certain death now rather than uncertain life on medical support systems. But the decision seldom comes easy, as a Newsweek reporter discovers during three weeks with the doctors, nurses, patients and families in an intensive-care ward. A best-selling guide to suicide fires debate over when it is right to let life go--and who should make that choice when the patient no longer can.  相似文献

In their zeal for lucrative insurance reimbursement, some private psychiatric hospitals seem to have gone over the edge themselves. A number of these institutions, critics charge, use outright coercion to commit and retain patients. Now some formerly abducted "recruits" are fighting back with lawsuits.  相似文献

This study examines the rapid growth of hospital wage rates and employment levels over the past decade, with particular attention to the period 1971-73, when wage and price controls were in effect throughout the economy. The analysis shows that the hospital regulations under the Economic Stabilization Program reduced real hospital wages below what they would have been in the absence of controls; a similar but smaller effect of the controls on hospital employment levels is also shown. This suggests that if the current HEW proposal for hospital cost containment is enacted, its impact would be a significant decrease in the rate of growth of hospital wages and employment.  相似文献

Using data from Wave II of the National Longitudinal Study of Adolescent Health (Add Health; Bearman, P. S., Jones, J., and Udry, J. R. http://www.cpc.unc.edu/projects/addhealth/design.html, 1997), we conducted multivariate analyses to examine three indicators of psychosocial adjustment (school belonging, self-esteem, depressive symptoms) and their associations with sexual attraction status, sex, and urbanicity. In general, sexual minority adolescents reported lower psychological adjustment than adolescents endorsing other-sex attractions only, with sexual minority females at particular risk. Further, differential patterns of risk for sexual minority youth emerged across rural, urban, and suburban communities. We conclude by discussing implications of these findings for addressing the psychosocial needs of sexual minority adolescents.  相似文献

Empathy, prosocial behavior, the number of friends, self-reported popularity, and various forms of interpersonal forgiveness were examined as predictors of peer victimization among 52 7th and 8th graders attending a private school. Popularity was the strongest individual predictor of teacher-reported victimization with high popularity associated with low victimization. Malestudents reported significantly higher rates of victimization than females, prompting the decision to examine correlates of self-reported victimization separately by gender. Interpersonal forgiveness scores were the strongest predictors of self-reported victimization; however, different forms of forgiveness were the greatest predictors of male and female self-reported victimization. Implications are discussed.  相似文献
