Postmortem examination of a former professional basketball player revealed an abnormal heart, most notably a single coronary artery. The literature on single coronary arteries is briefly reviewed, and the possible mechanism which caused the patient's condition is considered. This case is particularly unusual because of the patient's profession, which is so physically demanding. 相似文献

Following on the recent development of opportunity theory in criminology, we apply an opportunity approach to rape. Although rape is commonly viewed as a street crime, a substantial proportion of rape occurs inside homes following an unlawful entry of the residence. Drawing on this observation, we argue that rape and burglary, because they share a common locus in the home, should exhibit similar opportunity structures. That is, characteristics that place particular types of homes and householders at greater risk of burglary should also place (female) residents at greater risk of rape. An analysis of UCR rates and censusderived opportunity variables for 155 SMSAs in 1980 supports this position. We conclude that home-intrusion rape (rape following an unlawful entry of the home) is a violent crime with the opportunity structure of a property crime. 相似文献

Recently, various authors have examined the relationship between growth in government size and total economic growth. In each case, the authors permitted only a monotonic relationship. This paper examines the issue of a non-linear relationship between growth in government and overall growth in the economy.Government contributes to total economic output in various ways. The provision of Pigovian public goods enhances the productivity of the private sector inputs increasing total output. However, the public decision-making process can result in an inefficient quantity of public goods. The likelihood of this outcome increases with the size of government. Further negative effects are created by the revenue raising and spending mechanisms of government, and the increasing diversion of resources into unproductive rent-seeking activities. The magnitude of these effects is likely to increase with the relative size of government. 相似文献

This Article analyzes the development and complexities of the antitrust state action doctrine and the Local Government Antitrust Act as these doctrines apply to both "municipalities" and private entities. The restructuring of a public hospital is used as a model to facilitate the antitrust analysis. The restructuring model, which typically involves the leasing of a hospital facility by a public entity to a private nonprofit corporation, offers the unique opportunity to compare the different standards employed under the state action doctrine and the Local Government Antitrust Act. As a practical matter, the Article provides a framework for a public hospital to evaluate the impact of corporate restructuring on its antitrust liability exposure and to develop strategies to minimize antitrust risks. 相似文献
