In this paper, we investigate whether the school desegregation produced by court‐ordered desegregation plans persists when school districts are released from court oversight. Over 200 medium‐sized and large districts were released from desegregation court orders from 1991 to 2009. We find that racial school segregation in these districts increased gradually following release from court order, relative to the trends in segregation in districts remaining under court order. These increases are more pronounced in the South, in elementary grades, and in districts where prerelease school segregation levels were low. These results suggest that court‐ordered desegregation plans are effective in reducing racial school segregation, but that their effects fade over time in the absence of continued court oversight.  相似文献

The purpose of this study was to identify common factors in false allegation adult crimes, by examining the dynamics involved in 30 confirmed false allegation cases. The authors conducted a comprehensive review of these adjudicated cases and then completed a collection instrument to capture offender demographics, offense characteristics, and motive. The results indicated that most false allegation crimes were committed by women (73.3%) and Caucasians (93.3%). Data indicated that more interpersonally violent allegations were primarily motivated by attention/sympathy needs (50.0%), whereas more impersonal offenses involved other motivations such as providing an alibi (16.7%) or profit (13.3%). Offenders tended to be younger, high school graduates with no higher education (43.3%). A total of 23.3% of offenders had a prior criminal history. Male offenders appeared as likely as women to be motivated by attention/sympathy; however, men tended to select more violent, nonsexual offenses (e.g., attempted murder) than women.  相似文献

4-Methylmethamphetamine has been detected in samples submitted for analysis in several states throughout Australia. Six ring substituted methyl isomers of methamphetamine and amphetamine were synthesised and analysed. As the regioisomeric 2-, 3- and 4-methylmethamphetamine and 2-, 3- and 4-methylamphetamine have virtually identical mass spectra, the use of MS is an ineffective technique to discriminate between these closely related compounds. We set out to determine whether the regioisomers could be differentiated by a combination of GC-MS, acetyl derivatisation and GC-IRD. We demonstrate that the three isomers of methylmethamphetamine and methylamphetamine can be separated by GC, and a combination of acetyl derivatisation and vapour phase IR can identify the specific ring substituted compound.  相似文献

Examining qualitative historical evidence from cases of federal regulation in the areas of labor, civil rights, and environmental policy, this article provides support for the hypothesis that divergence between legislative and executive preferences—a core and distinctive feature of the American constitutional order—creates an incentive for Congress to rely upon private lawsuits, as an alternative to administrative power, to achieve its regulatory goals. It also shows that this mechanism encouraging statutory mobilization of private litigants had been operative long before its powerful growth started in the late 1960s, that it operated in similar fashion with Republican legislators facing Democratic presidents and Democratic legislators facing Republican presidents, and that it remained a source of controversy and an active influence on congressional decision making throughout the half century covering the 1940s through the 1980s.  相似文献

Abstract: Recent neuroimaging studies investigating the neural correlates of deception among healthy people, have raised the possibility that such methods may eventually be applied during legal proceedings. Were this so, who would volunteer to be scanned? We report a “natural experiment” casting some light upon this question. Following broadcast of a television series describing our team’s investigative neuroimaging of deception in 2007, we received unsolicited (public) correspondence for 12 months. Using a customized template to examine this material, three independent assessors unanimously rated 30 of an initial 56 communications as unequivocally constituting requests for a “scan” (to demonstrate their author’s “innocence”). Compared with the rest, these index communications were more likely to originate from incarcerated males, who were also more likely to engage in further correspondence. Hence, in conclusion, if neuroimaging were to become an acceptable means of demonstrating innocence then incarcerated males may well constitute those volunteering for such investigation.  相似文献
