Since about 2000, Russia became increasingly interested in a swift expansion of its oil and gas industry to the eastern regions, aiming primarily at the domestic development needs and new markets of Northeast Asia. Eastern Siberia and the Far Eastern areas contain up to 50 percent of Russia's estimated oil reserves. In this context, the Eastern Siberia–Pacific Ocean oil pipeline is attracting attention as a mega-project important not only for Russia, but also for its neighbors. This pipeline will facilitate the development of new oil fields in the remote eastern areas. There are also plans to build oil refineries connected to the pipeline, including the one planned on the Pacific coast. Indeed, Russia needs an access to the neighboring markets not only in the field of oil, but also natural gas and electricity. In this regard, long-term shared interests should drive new energy projects, and governments could greatly facilitate business interaction. Moreover, specific measures dealing with the long-term energy policies are required at the national, bilateral and regional levels, including practical and project specific initiatives tailored to the needs of the economies of Northeast Asia, considering their large markets, geography, technological potential and an interest in building institutions.  相似文献

Increasingly, public administration in the United States operates in a densely interconnected international system in which local decisions and actions may trigger global repercussions—and vice versa—and the fate of communities in one region is bound to the choices of decision makers elsewhere. Administrative actors have become enmeshed in a complicated, interwoven pattern of governance in ways that shape actions, issues, and opportunities for influencing administrative agencies at national, state, and local levels. These developments call for a critical reappraisal of our inherited notions of governance, management, and accountability. Terrorist tragedy and responses to it call attention to these themes, but they apply broadly across the spectrum of governance challenges. To demonstrate this point, we analyze some implications of transnational governance for the institutions and practices of U.S. public management, with particular attention to another subject: environmental policy and management. A conclusion is that the public administration community must adjust traditional practices to facilitate the effective management of the global processes that, in turn, reshape the world.  相似文献

This paper analyzes the work of Mosquitia Pawisa (MOPAWI) in relation to the development of its strategic linkages among the grassroots, the state, and ultimately the international level of politics in practice. Over the years, MOPAWI has developed a large and complex program addressing many aspects of development in La Mosquitia. Working strategically at two levels, MOPAWI has endeavored to change government policy for the region through continued lobbying and advocacy. It has also worked alongside with local communities to find ways of improving livelihoods without harming the environment. The key strength of the MOPAWI work has been the high level of community participation and mobilization by managing their own development in a time of profound change. Overall, the experience of MOPAWI suggests that nongovernmental organizations can play a strategic role in obtaining environmental protection, government recognition of ethnic diversity, and rights for indigenous people.  相似文献

An intoxication following administration of morphine, tramadol and atracurium in a suicide case is reported. The route of administration and the amount of the particular drug were known from the investigation of the death scene and the findings of the postmortem examination. Tramadol was present in the gastric contents as well as in blood, liver, kidney and brain samples, whereas the drug could not be detected in muscle. All body fluids and tissues investigated contained morphine as well as its 3- and 6-glucuronides with the exception of muscle tissue. The concentrations of morphine and its glucuronide metabolites were determined by LC/MS following solid phase extraction. Interestingly, the concentration of M6G in brain, liver and kidney were close to the concentration of M3G in the particular tissue. This phenomenon might be explained by a preferential hydrolysis of M3G or by a preferential formation of M6G postmortem. Measurement of morphine and M6G in femoral blood and cerebrospinal fluid may be a useful indicator in rapid deaths.  相似文献

Allele and genotype frequencies for three recently described short tandem repeat loci D1S1656, D12S391, and D18S535 were determined in a population sample from Asturias (North Spain). The loci were amplified using a fluorescence based PCR method and were typed automatically. No deviation from Hardy-Weinberg expectations were observed. The three loci proved to be highly discriminating and the allele frequencies observed are similar to those of the other European populations that have been typed for these loci to date.  相似文献
