Research on U.S. congressional elections has placed great emphasis on the role of competitiveness, which is associated with high levels of campaign spending, media coverage, and interest group and party involvement. Competitive campaigns have been found to increase citizens' participation, engagement and learning. However, little is known about whether the effects of competitive campaigns have enduring consequences for citizens' attitudes and behavior. Analyzing a survey of citizens conducted one year after the 2006 congressional elections that includes an oversample of respondents from competitive House races, we examine whether exposure to a competitive House campaign affects voters' political knowledge and political interest as well as their consumption of political news. We find that competitive elections have positive effects that endure for at least a year beyond the campaign season, reinforcing the idea that political competition plays a robust role in American representative democracy.  相似文献

Despite the recent surge in research linking animal and human acts of violence, relatively few studies have been conducted examining animal cruelty itself. Although several researchers have begun to identify some of the correlates of animal cruelty, few have attempted to understand how differences in the backgrounds of rural and urban residents have led to their abuse of animals. Using survey data from 180 inmates, this study examines how demographic characteristics, exposure to animal cruelty in childhood, and the target animal's relationship with the abuser have contributed to the frequency of acts of animal cruelty in urban- and rural-based settings. Unlike their urban counterparts, rural respondents who engaged in recurrent animal cruelty were more likely to have witnessed family members and/or friends abuse an animal. Moreover, rural respondents who engaged in recurrent animal cruelty abused pet and stray animals, whereas recurrent animal abusers who grew up in urban areas tended to abuse pets only. These findings suggest possible place-based differences in the etiology of recurrent animal cruelty.  相似文献

Investigations of perinatal deaths often result in discrepancies between autopsy findings and witness accounts. The mechanism by which the umbilical cord is severed after delivery is a common quandary. Confirming or refuting the mother's stated method frequently has significant investigative importance; however, a surprising paucity of data currently exists to allow an objective opinion about the likely mechanism. Ninety-nine placentas with umbilical cords were examined. By random selection, each cord was severed by one of the following tools or mechanisms: knives, scissors, traction, or crush. Each break was examined and photographed, and a tissue section from the broken end examined microscopically. Differentiation of mechanism was best done grossly based on specific pattern recognition. Umbilical cords severed by blunt force have distinctly different morphology from those severed by sharp force. Even similar-appearing sharp force transections frequently have mechanism-specific distinctive patterns of injury.  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

While there is little consensus as to the exact form and structure of an academic criminal justice program, the traditional model of higher education, with its emphasis on qualified and productive faculty, has gained popular acceptance in the past decade. Concurrently, graduates of criminal justice programs have often found that prospective employers do not value their degrees. This article explores the relationships between student evaluations of their educational experiences, the structural characteristics identified as essential to an educational program, and the mechanisms used by ex-students to reduce dissonance caused by employer rejection or a poor job market.In 1980 a total of 411 recent graduates of eight criminal justice programs in Louisiana responded to a questionnaire designed to measure their attitudes toward and evaluations of their educations. Several key structural variables frequently associated with quality higher education failed to predict student evaluations. Two exceptions were ration of senior faculty and ratio of ex-police as faculty, and the effects of these variables on student evaluations were inverse. Overall, the best predictor of the saliency of one's educational experiences was the student's evaluation of the current job market in criminal justice. This variable was followed, in descending order by sex, ratio of faculty with senior rank, years since graduation, type of degree granted, and ratio of ex-police as faculty.  相似文献
