A finding in the autopsy of John Paul Jones, the American Revolutionary War naval hero, may explain his terminal illness. During his last 2 years, he had a persistent productive cough and dyspnea. Ten days before death, he developed rapidly progressive dependent edema and ascites. He died in France in 1792. His body, preserved in alcohol in a lead coffin, was, in 1905, removed to the United States. Glomerulonephritis was noted on an autopsy, performed in France, but there was no comment then or since about ventricular wall thickness being the same in both ventricles at 5–6 mm. Hypertrophy and dilatation with biventricular failure followed by tissue shrinkage during 113 years in alcohol could have resulted in these ventricular wall findings. Systemic hypertension and left ventricular failure are consistent with his respiratory symptoms complicated perhaps by pulmonary emboli, right ventricular failure with tricuspid regurgitation, peripheral congestion, and jaundice.  相似文献

Programs that involve multiple levels of government may suffer from a principal‐agent problem: Lower levels of government may wish to pursue different objectives than the higher level of government that provides funding. One strategy for dealing with this problem is to establish a performance management system where units operating the program are accountable for meeting performance standards and are rewarded or sanctioned depending on how well they perform. Title II‐A of the Job Training Partnership Act provides training for economically disadvantaged adults and has operated under a performance management system since 1983 when the program was established. The federal government's goal for the program is to maximize impact on the employment and earnings of participants, but because control groups are not available for the 640 local programs, proxy measures of performance must be used. In this paper, data from an experiment in 16 sites are used to determine how closely measured performance corresponds to program impact. It is concluded that there is only a weak correspondence between the two measures and that the Department of Labor should avoid making significant rewards or sanctions based on the current performance management system. © 2000 by the Association for Public Policy Analysis and Management.  相似文献

Previous methods of analyzing the substance of political attention have had to make several restrictive assumptions or been prohibitively costly when applied to large-scale political texts. Here, we describe a topic model for legislative speech, a statistical learning model that uses word choices to infer topical categories covered in a set of speeches and to identify the topic of specific speeches. Our method estimates, rather than assumes, the substance of topics, the keywords that identify topics, and the hierarchical nesting of topics. We use the topic model to examine the agenda in the U.S. Senate from 1997 to 2004. Using a new database of over 118,000 speeches (70,000,000 words) from the Congressional Record , our model reveals speech topic categories that are both distinctive and meaningfully interrelated and a richer view of democratic agenda dynamics than had previously been possible.  相似文献

The article here extended reflects on the excessively narrow debate over the government-sponsored enterprises (GSEs)' cost-benefit transfer balance which had been raging for a quarter-century before the 2007–2009 financial crisis. That crisis has cast a new light on the actual costs of GSE operations and exposed the unsustainability of some of their benefits for homeownership. After injecting afew new findings into the traditional debate, this comment adds some of what has transpired in recent years and what may be inferred from it so far. Doing so brings additional analysis to bear on the article's conclusion that “the GSEs might not be justified” and “Maybe it is time for them to exit” although most politicians in the past have been disinclined to show them the door.  相似文献

Abstract

The first question people typically ask about homelessness is, “How many people are homeless?” After that, questions usually turn to characteristics: “What are they like?” Basic demographic characteristics such as sex, age, family status, and race have always been of interest, in part because the homeless population appears to be very different from the general public and even from most poor people who are housed with respect to these characteristics. Often, because these differences are so dramatic, demographic characteristics are overinterpreted as representing the reasons for homelessness.

But as various studies have documented, most demographic factors quickly disappear as proximate causes when other factors representing personal vulnerabilities are available for examination. The underlying causes of homelessness, the structural conditions of housing and labor markets that turn vulnerabilities into loss of housing, do not lie within individuals at all and are thus difficult to include in analyses based on individual data.  相似文献
