With Bill Clinton's new reforms only a month away, the health-care system is on the operating table--and the doctors are under the knife. Americans have a love-hate relationship with physicians: they like the care that doctors provide but hold them to blame for the nation's health-care mess. NEWSWEEK looks at how the culture of medicine may change, assesses doctors' fears--and examines the brave new world of HMOs.  相似文献

This article builds a composite index, the Central American Integration Index (IIC-AMPI), to measure economic integration. This index utilises a robust methodology and conceptual framework. The study shows that IIC-AMPI is responsive to variable changes and resistant to outliers. The findings indicate that the Deep Integration Process initiative dominates the current integration trend, as seen in the regional average score from 2015 to 2017, aligning with Guatemala and Honduras. Nicaragua demonstrates the most consistent progress, while Panama lags behind. The evidence supports the Customs Union as Central America's future integration path, highlighting the index's ability to capture the dynamic reality of economic integration.  相似文献

The present research explored factors thought to affect compensatory awards for non-economic ham (pain and suffering) in personal injury cases. Experiment 1 showed that the nature and severity of the plaintiffs injury had a strong effect on perceptions of the extent of harm suffered and on award amounts. The parties' relatively active or passive roles in causing the injury affected assessments of their degree of fault, but perceived fault had little influence on awards. Experiment 2 replicated with more varied cases the strong impact of injury severity on harm perception and on awards for pain and suffering. In both studies, the disability and the mental suffering associated with injuries were stronger predictors of awards than were pain and disfigurement.  相似文献

This article will trace the history and effects of the PPI from the time of its original concept by the FDA in the early 1970's to its current status. It will also address the response to this FDA initiative by the industry, medical community and consumer groups. Initiatives in other countries and future issues will also be discussed.  相似文献

The outcome of the 1992 U.S. presidential election has been explained largely as a function of perceptions of George Bush's economic performance. The economy submerged questions about Bill Clinton's character, awarding the advantage to the Democrat. In this article, we evaluate the effect of economic evaluations along with character attacks on candidate support in the 1992 presidential contest. Claims that the economy submerged character have been somewhat exaggerated. But while character remains an important issue in presidential evaluation, its role in judging candidates cannot be taken at face value. We show that both economic evaluations and character judgments are highly politicized. The findings indicate that those protesting Clinton's character turned almost exclusively to Bush. Those protesting Bush's economic record turned to both Perot and Clinton. Still, the economy did not trump character. The troubles of both major party candidates fueled a strong protest vote that contributed to Perot's strong showing.  相似文献
