The conflict and animosity that sometimes accompanies child custody disputes can give rise to the propagation of allegations of child sexual abuse. To characterize the magnitude of the problem, the present study attempted to determine whether and to what extent child sexual abuse allegations predominate in family court litigation. The entire one-year caseload of a county family court docket was systematically reviewed and coded. Methodical evaluation of 603 family court files yielded base rates of pertinent allegations and other information profiling the cases. The findings did not support the contention that sexual abuse allegations are commonplace in child custody disputes. Sexual abuse allegations were made in 2% of cases in which custody or access was contested and in only 0.8% of the cases overal. Implications of the findings for future research were discussed.The authors gratefully acknowledge the assistance of the Honorable William R. Campbell and Barbara Scott, Clerk of Court for the South Carolina Fifth Judicial Circuit, as well as the contributions of Angie Newton, Frank Robinson, and Kimberly Ellis in the data collection process.  相似文献

Federal transportation officials assert that labor protections in the Urban Mass Transportation Act inhibit the propensity of local transit agencies to contract with private firms for services. The authors present results from a survey of a large sample of transit managers and econometric analysis to support their conclusion that labor protections do not appear to reduce the incidence of contracting. The labor protections, however, may be costly to transit management in other ways. The authors recommend actions, aside from repeal of labor protections, to increase contracting by local transit agencies.  相似文献

Compared to the practice in other professional schools and academic fields at universities, law professors are hired at a young age based primarily upon their academic merit determined through grades, class rank, and school rank. This emphasis upon narrowly defined academic merit—apart from achievement demonstrated through original scholarship or experience in professional practice—first emerged during "the professionalization of the American law professor" between 1870 and 1900 at Harvard Law School (HLS). Though normative today, this outcome was neither necessary nor uncontested. In the late nineteenth century the new standard of hiring faculty according to their academic merit was energetically opposed by those favoring the antecedent standard of professional experience and reputation. Only when financial considerations counterbalanced that traditional standard did hiring decisions tip in favor of the new principle. Not until the early 1900s, when the second generation of academic meritocrats dominated the HLS faculty, did the new hiring standard become unequivocally established as policy in the school and, by extension, in legal education.  相似文献

Abstract: Taxes on betting are a major source of revenue for Australian state governments. Specific taxes on the racing industry date from 1915. However, the revenue potential has only been tapped in all the states since the legalisation in the past 30 years of off-course betting through the state-run totalisator (TAB). The introduction of the TAB followed a long period when various states adopted different policies towards off-course betting, ranging from legalisation of bookmakers' betting shops to attempts at complete suppression. In tracing the history of these policies, the focus is on "implementation failure", or the many administrative pitfalls and obstacles that were experienced. These include insurmountable tax evasion by bookmakers, regulatory capture of betting boards by bookmakers and corruption of the law enforcement agencies. State governments also had to accommodate a range of conflicting interests, including the interests of the racing industry itself and the demands of the anti-gambling lobby. The TAB is shown to be a happy and convenient resolution of most, but not all, of these administrative and political dilemmas.  相似文献

Ethanol was determined by gas chromatography in a variety of tissues and body fluids secured at autopsy in 61 cases. The specimens tested included right and left heart blood, femoral blood, pericardial fluid, cerebrospinal fluid, vitreous humor, urine, stomach contents, and brain. Statistical analysis of the cases revealed no significant differences among the various blood sites tested. However, the variations in blood ethanol concentrations among the various sampling sites within each case were as follows: 40 cases showed differences of less than 25%; 16 cases revealed variability between 25% and 50%, 4 cases had differences exceeding 50%. In one case, satisfactory blood analyses could not be accomplished. The larger variances occurred especially in those instances in which stomach alcohol concentration was 0.50% or greater. In one case, the variability amongst the different blood sites exceeded 400% (femoral blood--0.043%, right atrium--0.070%, root of aorta--0.156%); the brain was 0.050%, and the stomach contents was 1.2%. For all 61 cases, variances in blood alcohol content among the different sampling sites in a single cadaver ranged from 1.8 to 428%.  相似文献

Recently criminologists have begun to explore the importance of disaggregating frequency measures of self-reported delinquency into the separate decisions of initiation and continuation. Given that labeling makes predictions concerning continuation, the purpose of this paper is twofold. The first is to test the ability of an informal labeling model to predict the decision to continue delinquent behavior once it is initiated. The second purpose is to address the broader question of whether disaggregation matters. The findings support the idea that the informal labeling model is predictive of the decision to continue delinquent behavior. The findings also suggest that, at least for a measure of general delinquency, there are some differences to be found by choosing the appropriate sample and form of the dependent variable.  相似文献

Do Lawyers Cause Adversarial Legalism? A Preliminary Inquiry   总被引:2,自引:1,他引:1  
Cross-national case studies have indicated that compared to other economically advanced democracies, American methods of policy implementation and dispute resolution are more adversarial and legalistic, shaped by costly court action or the prospect of it. To what extent are lawyers responsible for creating American-style adversarial legalism? This article argues that while adversarial legalism stems primarily from enduring features of American political culture and governmental structure, the legal profession plays a significant independent role in promoting and perpetuating this mode of governance.  相似文献
