We consider the contributions made by Robert H. Bork's Coercing Virtue (2003) and Anne-Marie Slaughter's A New World Order (2004) to the ongoing debate over the citation of foreign law in United States courts. While empirically minded sociolegal scholars might be tempted to dismiss these books as mere op-eds, that would be a mistake. Taken with the spate of other recent work, they supply the makings of an agenda for rigorous research devoted to understanding the exchange of law among nations.  相似文献

The possible contribution of poppy seed foods to positive opiate urinalysis results, especially from foods available in the Pacific Rim area, has recently become an issue for the U.S. Army Forensic Toxicology Drug Testing Laboratory in Hawaii. To assess the likelihood of this possible contribution, seven different poppy seed food products were consumed by male and female volunteers, and urine specimens were collected at time increments up to either 24 or 72 h. Specimens were evaluated for opiates using Roche Abuscreen radioimmunoassay (RIA), and all RIA positive specimens were analyzed for morphine and codeine using gas chromatography/mass spectrometry (GC-MS). Poppy seed cake, bagels, muffins, and rolls did not contain sufficient quantities of poppy seeds to give rise to opiate positive specimens by U.S. Department of Defense (DOD) GC-MS cutoff levels (morphine = 4000 ng/mL, codeine = 2000 ng/mL), although a number of specimens were positive by National Institute on Drug Abuse (NIDA) cutoff levels (morphine and codeine = 300 ng/mL). However, ingestion of poppy seed streusel or Danish pastry led to confirmed morphine and codeine positive specimens, irrespective of the use of DOD or NIDA confirmation cutoff values. In addition, significant amounts of codeine were observed in a number of these specimens. These findings argue against the unqualified application of previously published quantitative guidelines for eliminating poppy seed ingestion as a possible cause for a positive opiate urinalysis result.  相似文献

Research has indicated that school factors such as communal school organization and student bonding are predictive of school disorder, with greater communal organization and greater student bonding leading to less delinquency and victimization. Data from a nationally representative sample of 254 public, nonalternative, secondary schools were used to examine structural equation models representing hypothesized relationships among communal school organization, student bonding, and school disorder. The hypothesis that communally organized schools would have less disorder held true for teacher victimization and student delinquency, but not for student victimization. In addition, the hypothesis that the relationship between communal school organization and school disorder would be mediated by student bonding was supported for student delinquency, but not for teacher victimization.  相似文献

Corporate social responsibility (CSR) is increasingly being promoted as an instrument for global governance to address the regulatory vacuum surrounding transnational business activities and as a method for encouraging business to contribute to sustainable development at the national level. Originally a business-driven, American concept, CSR has now been adopted and promoted by a wide range of governments and multilateral institutions. However, the socio-political model underlying CSR is far from neutral and may conflict with existing models in the societies in which it is introduced. In this article a typology of possible governmental interpretations of CSR is developed, and how CSR is transformed and adapted in its meeting with Nordic governments in order to fit the “Nordic Model” of state-market-society relations is analyzed. The analysis suggests that pre-existing political-economic institutions and cultural norms deeply affect the interpretation of CSR, and that this, when combined with ongoing national political processes, leads to a highly transformed concept of CSR.  相似文献
