Hospices, unheard of in this country a few years ago, have become a fast-growing American phenomenon. They promise effective pain relief for terminal cancer patients as well as a warm, homey atmosphere where fear and loneliness are minimized. Hospices are basically a creation of the British and it is still unclear how--or even whether--the principles they embody can be successfully incorporated into American medicine. However, hospices can make an important philosophical contribution by showing the way toward removing the stigma attached to death. Hospice principles also have implications for all of health care, in emphasizing the importance of treating the whole person rather than just the disease. 相似文献

Institutional litigation, in which courts are requested to oversee the operation of large public institutions, has been frequently attacked as a departure from the traditional model of litigation. In this Article, Professors Eisenberg and Yeazell argue that the procedures and remedies employed in institutional litigation are not unprecedented but have analogues in older judicial traditions. Nor, they assert, do the doctrines of separation of powers and federalism present any obstacles to institutional litigation. They conclude that the novelty lies in the newly created substantive rights which courts are asked to enforce. 相似文献

John A. C. Conybeare 《Policy Sciences》1980,12(1):27-39
A basic tenet of the new conservatism in political economy is that government policies frequently lead to unintended consequences which may offset the benefits of the policy. Auto safety legislation may be a case in point. As the first country to make the wearing of seat belts compulsory, Australia is highly suitable as a case study. Traffic accident casualties were regressed on six independent variables for the pre-seat belt period 1949–71. The equations were then used to predict casualties for the period 1972–77, using the actual values of the independent variables. In the aggregate, predicted occupant casualties were higher than the actual rates, whereas non-occupant casualties were underpredicted by the equations. An additional test, using a dummy variable to predict the effect of seat belts, supported these conclusions. The results are consistent with the hypothesis that drivers respond to a reduction in risk by increasing driving intensity, shifting some of the welfare cost of auto safety legislation on to non-occupants, whose casualty rates are higher than they would have been in the absence of seat belt legislation.I am grateful to Chris Adam and to an anonymous reviewer for helpful comments and suggestions. 相似文献
