A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning. 相似文献

Drawing on the strategic surprise, warning-response, and foreign policy literature, this article argues that the September 11 terror attacks should be regarded as a strategic surprise and examines a number of key factors that contributed to vulnerability and inhibited vigilance. Three broad explanatory "cuts" derived from the literature—psychological, bureau-organizational, and agenda-political—are deployed to sift through the rapidly expanding empirical record in an effort to shed light on the processes and contextual factors that left the United States vulnerable to the attacks. The article aims to improve our understanding of generic processes and practices that enhance or detract from vulnerability and vigilance. 相似文献

国际环境争端解决机制研究 总被引:4,自引:0,他引:4
解决和避免国际环境争端已成为近年来备受关注的论题。无论是在1992年联合国环境与发展大会期间还是新近多边环境协定的谈判和实施过程中,国际环境法的遵守问题都引起了各国政府和国际法学者的关注。多边环境条约、联合国海洋法公约以及WTO规则,是国际环境争端解决机制的主要法律渊源。在一定范围内,这些多边条约和条约体系相互影响、相互推动,又相互矛盾和冲突,呈现出国际环境争端解决机制的独特发展形态。 相似文献

Decomposition studies were conducted using two carcasses of domestic pigs, Sus scrofa L., 8.4 kg and 15.1 kg in weight, to determine the effects of carcass size on the rate of decomposition, composition of the arthropod fauna, and succession patterns. A total of 46 arthropod taxa were recovered during this study. No size-related differences were observed between carcasses with respect to composition of the arthropod fauna or patterns of succession. A greater number of arthropods were observed attracted to the 15.1-kg carcass, and the rate of decomposition observed was more rapid for the 15.1-kg carcass than for the 8.4-kg carcass. Internal temperatures of the 8.4-kg carcass were more directly related to external ambient temperatures during the fresh and bloated stages of decomposition. During the decay stage, both carcasses generated internal temperatures significantly above ambient temperatures. Following this stage, internal temperatures fell to approximate ambient temperatures during the postdecay and remains stages. 相似文献

The failure of forestry to contribute to poverty reduction in Central America is due to public policies which inhibit its profitability. Absence of public regulation of harvesting and competing subsidies to agriculture keep forestry stumpage prices artificially low. This encourages destruction of the forest resource, which damages both the environment and the potential to reduce poverty. A comparison of Costa Rica and Honduras reveals two dissimilar approaches toward forest policy. While Costa Rica attempts to raise producer and grower stumpage prices by tax credits, soft loans and differential species fees, Honduras enforces price ceilings and uses centralized authority to control forest production and export. Both countries exhibit weaknesses in the management control cycle of programming, budgeting, implementing and evaluating their forest policies. Yet the Costa Rican approach has increased stumpage prices already, which bodes well for their forest sector. By contrast, the major beneficiary of Honduran forest policy has been COHDEFOR, the state enterprise responsible for forestry management, controlling production, and running its national system of agroforestry cooperatives. Despite greater public authority and resources than the Costa Rican forest service (DGF), the Honduran forest policy is not likely to increase producer profitability or reduce poverty in the near future. 相似文献

This article examines the impact of nongovernmental organization-sponsored contact and communication on fostering peaceful solutions to ethnic conflict via case studies of the activities of the Project on Ethnic Relations (PER) in Romania, Macedonia, Montenegro, Kosovo, and Serbia. It explores five operational principles that guide PER activity: creating credible, neutral forums for dialogue; maintaining momentum; working within political realities; encouraging indigenous solutions from within existing processes; and acting with the backing of powerful states. These principles explain PER's success as a "weak mediator" of ethnic conflicts. According to this analysis, PER also exhibits organizational characteristics that contribute to success, including nonpartisanship, area expertise and extensive networks of local contacts, and an ability to secure the trust of local actors.
A significant indicator of the success of PER activities is the establishment by conflicting parties of institutionalized mechanisms for addressing their differences. Contrary to the view that electoral competition contributes to conflict, this study finds that the possibility of achieving an electoral advantage by participating cooperatively in conflict resolution activities creates incentives for local actors to recognize opportunities offered by PER activities and leads local actors to heed PER's advice. Finally, the article offers a cautionary observation. While PER's perceived influence with major international actors may contribute to its local successes, once a state actor with the power to impose a solution has committed itself to ending a conflict, its preferences outweigh any local interests in determining the outcome and renders the efforts of a "weak mediator" such as PER irrelevant. 相似文献
