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

This article addresses some of the implications of the EU's proposed Marine Strategy Directive for ongoing work in the regional seas conventions and for national work on regional marine strategies. The starting point is the proposed directive's focus on the ecosystem approach to the protection of the marine environment. Key elements within this approach are analysed, such as integration of environmental considerations into other policy areas; introduction of ecological quality objectives; and establishment of holistic monitoring and assessment programmes. Is it possible to transform these concepts into legally binding obligations? What will the implications of the proposed directive be for the rights and obligations of EU Member States under international law? A Management Plan for the Norwegian Part of the Barents Sea ('Barents Plan') was adopted by the Norwegian Government in March 2006 and approved by the Norwegian Storting (Parliament) in June 2006. It provides an example of a concrete application of the concepts in the proposed directive. Based on an analysis of the proposed Marine Strategy Directive and the Barents Plan, some key political and legal challenges are discussed in this article.  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
