Proposals to ration health care in the United States meet a number of objections, symbolic and literal. Nonetheless, an acceptance of the idea of rationing is a necessary first step toward universal health insurance. It must be understood that universal health care requires an acceptance of rationing, and that such an acceptance must precede enactment of a program, if it is to be economically sound and politically feasible. Commentators have argued that reform of the health care system should come before any effort to ration. On the contrary, rationing and reform cannot be separated. The former is the key to the latter, just as rationing is the key to universal health insurance.  相似文献

Incarceration rates in the United States dramatically increased over the past several decades. This trend has drawn significant academic attention to prison overcrowding and its potential effect on inmate misconduct. The empirical relationship between inmate misconduct and overcrowding, however, is less than clear. To be sure, studies indicating positive, negative, and null relationships can all be found in the literature. The current research subjects this body of literature to a meta-analysis in an effort to: (1) clarify the direction and strength of the relationship between overcrowding and rates of prison misconduct across all studies, and (2) to uncover the degree to which variation in research outcomes can be attributed to methodological differences across studies. Results indicate that prison crowding has little substantive impact on inmate misconduct. Implications of the findings are discussed in detail.  相似文献

Those in need of employment and training programs face a variety of difficulties. Accordingly, the federal response to labor market problems has encompassed a wide range of initiatives. These include preparing people for work (through skills training, the Job Corps, work experience programs); improving the functioning of the labor market (through matching workers with jobs, establishing a minimum wage, and the Targeted Jobs Tax Credit program); and preventing discrimination. Unresolved issues in these areas are examined. They include who should be targeted for federal assistance, which levels of government can best operate programs, how public versus private efforts should be balanced, how limited resources should be distributed, and how the welfare versus work question should be resolved.  相似文献
