Sixteen percent of children 6-11 years of age were classified as overweight in 1999-2002, four times the percentage in 1965. Although poverty has traditionally been associated with underweight as a result of poor diet, researchers have recently pointed to a paradox in the U.S., which is that low income and obesity can coexist in the same population. This paper first examines whether income is linked to overweight in school-age children. Second, it explores whether food programs such as the Food Stamp Program, the National School Lunch Program, and the School Breakfast Program are associated with overweight among children in different income groups. The data come from the nationally representative 1997 Panel Study of Income Dynamics Child Development Supplement. No evidence either that poor children are more likely to be overweight or that food programs contribute to overweight among poor children was found. 相似文献

This paper examines whether a random sample of adults can apply local contemporary community standards regarding the acceptability of explicit sexual material. Inasmuch as the legal test employed in the U.S. for determining obscenity requires a jury to apply such standards, the research examines the practicality of such an approach. The analysis indicates that the best predictor of what an individual will perceive the community standards to be is the individual's own standards concerning sexual material. The implications of these findings are examined from both a legal and social science perspective. In addition, the consequences of not providing jurors information concerning local standards are discussed.A previous version of this paper was presented at the Annual Meeting of the Law and Society Association in Chicago, May 29–June 1, 1986. The authors wish to thank Debbie Edwards, Jane Warne, and the anonymous reviewers fromLaw and Human Behavior for their helpful comments and suggestions concerning the paper. 相似文献

In the absence of a bankruptcy law, private debt collectionremedies generally result in an ad hoc disposal of the debtor'sassets, which reduces the aggregate value of creditors' claims.We show that creditors will often choose not to write privatecontracts that would prevent this inefficient behavior, eventhough these contracts would be to the mutual benefit of allcreditors. Our analysis therefore provides an economic rationalefor the existence of a bankruptcy law that makes a collectiveresolution compulsory for all creditors. We argue that sucha mandate is a requisite part of any effective bankruptcy system,including proposals for market-based resolutions of insolvency. 相似文献

An attributional examination of retributive versus utilitarian philosophies of punishment 总被引:4,自引:0,他引:4
Two basic goals of punishment—retribution and utility—and the means to those goals, including isolation, rehabilitation, and
the creation of fear, were first examined. The objectives of punishment were then related to attributions regarding the cause
of a transgression. It was documented that punishment goals are mediated by the expectancies and affects that are elicited
by causal beliefs. It also was argued that the purposes of punishment are more state-like than trait-like, for they change
as a function of the reason for a transgression. Data from three laboratory experiments, as well as a field study regarding
reactions to O. J. Simpson for his alleged crimes, were presented in support of the above beliefs. In addition, the morality
of retribution versus utilitarianism was discussed in the context of the caning of Michael Fay in Singapore. It is suggested
that rehabilitation may be the most moral of the punishment means. 相似文献
