The article presents the results of an examination of the dry residue of liquor crystallograms (DRLC) using infrared spectroscopy technique. 36 spectrograms were studied. Elements of similarity and difference were revealed in the spectrograms of organic substance (antifreeze, sodium cyclamate and fatty tissue), of DRLC of the crystal-forming matter CuCl(2)x2H(2)0, of DRLC of a live person and cadaveric liquor (with no brain injury in respective case histories), of DRLC of liquor of live persons with a brain injury, of DRLC of liquor of persons who died of a brain injury and of persons who died of other causes. 相似文献

103 studies of torn aneurysms in the cerebral vessels are described. Localizations, morphological peculiarities of aneurysms as well as the nature of intracranial hemorrhages caused by torn aneurysms are presented. The authors have a critical attitude to the "acquired" theory of aneurysm development. 相似文献

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

The compromise enhancing effect of lobbying on public policy has been established in two typical settings. In the first, lobbies are assumed to act as “principals” and the setters of the policy (the candidates in a Downsian electoral competition or the elected policy maker in a citizen-candidate model of electoral competition) are conceived as “agents”. In the second setting, the proposed policies are solely determined by the lobbies who are assumed to take the dual role of “principals” in one stage of the public-policy game and ‘agents’ in its second stage. The objective of this paper is to demonstrate that in the latter setting, the compromising effect of lobbying need not exist. Our reduced-form, two-stage public-policy contest, where two interest groups compete on the approval or rejection of the policy set by a politician, is sufficient to show that the proposed and possibly implemented policy can be more extreme and less efficient than the preferred policies of the interest groups. In such situations then more than the calf (interest groups) wish to suck the cow (politician) desires to suckle thereby threatening the public well being more than the lobbying interest groups. The main result specifies the conditions that give rise to such a situation under both the perfectly and imperfectly discriminating contests. 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

Adolescent Intimacy Revisited 总被引:3,自引:0,他引:3
Shulman Shmuel Laursen Brett Kalman Zwi Karpovsky Sigal 《Journal of youth and adolescence》1997,26(5):597-617
Two studies examined intimacy in adolescent friendships. In the first, 7th-, 9th-, and 11th-grade students completed a questionnaire assessing perceived friendship intimacy. Age and sex differences were identified in emotional closeness, self-disclosure, emphasis on individuality, control, and conformity. Across ages, emphasis on individuality increased, whereas control and conformity declined. There were no age differences in emotional closeness and self-disclosure. Females reported more emotional closeness and self-disclosure than males. In the second study, individual differences in friendship intimacy were examined in a sample of 9th-grade adolescents. A joint problem solving task identified interdependent and disengaged friends. Perceived intimacy among interdependent and disengaged friends was contrasted with that in a control group of subjects without friends. Adolescents with friends reported more closeness than those without friends. Interdependent friends reported greater levels of respect for individuality than disengaged friends. The results underscore the salience of intimacy for peer relationships during the adolescent years and suggest that intimacy may be an important construct distinguishing between different types of close friendships. 相似文献
