The rare event of a corpse immersed in glacier ice becoming exposed on a glacier surface is closely connected with the glaciological conditions at the scene and the site of the accident. Provided that the time since death is known, certain questions relative to the circumstances of a mountain accident can only be answered by considering glaciological aspects. How the scene of an accident can be reconstructed by inference from the site of discovery is discussed by means of three exemplary cases that occurred on Tyrolean glaciers (Austria) during the past 40 years: (1) Two corpses were discovered close above the equilibrium line in the accumulation area after 25 years. The two victims had fallen down a rock face after the breaking off of a cornice and had come to rest in the uppermost part of the accumulation area. (2) A victim was discovered in the lower ablation area 8 years after falling down a crevasse in the middle part of the ablation area. (3) A female alpinist was discovered at the very end of the glacier after 29 years; it was concluded that the accident must have happened in the accumulation area. 相似文献

This article contributes to the development of theories on European integration by testing and exploring statistical models
on the long-term development of legislative activity of the European Commission. Drawing on legal information gained from
the European Union’s PreLex database and analyzing it with the help of statistical analyses, we map out growth patterns of EU law between 1976 and 2003.
We construct time-series models and models based on non-linear regression. While the performance of models based on the traditional
theoretical approaches, intergovernmentalism and neo-functionalism, is rather poor, the analysis suggests that nonlinear dynamic
models might be an interesting avenue for future conceptualizations of the EU integration process.
This article is based on a paper presented at the ECPR Standing Group on the European Union Second Pan-European Conference on EU Politics, “Implications of a Wider Europe: Politics, Institutions and Diversity”, 24–26 June 2004, Bologna, Italy. We would like to
thank the seminar participants for useful comments. 相似文献

This article explores the different and sometimes conflicting explanations of the success of the collective enterprises (town–village-enterprise) in China during the first phase of transition (1979–1995). It is argued that explanations, relying on cultural variables are not sustainable and this for two reasons. First, the importance of the collective enterprise is shrinking while the private sector is clearly on the rise. Second, other factors, referring to characteristics of the local and central political, administrative and economic environment, in which the Chinese enterprise has to (had to?) operate, provide for a sufficient explanation of the peculiar structure of the Chinese collective enterprises. These enterprises are seen as the result of ?bureau-preneurship’ because local bureaucrats were integrated in their management in order to pre-empt predatory behaviour and to facilitate the relationships with the central institutions. The article contributes to the property rights’ theory of the firm as it analyses an empirically very important case in which firms with unclear property rights and structures, apparently not conducive for incentives, might still be the most efficient option. 相似文献

Terrorism is a notoriously plastic word, depending on user, audience, and political context. This paper focuses on shifts
in its meanings since the early 1970s. As federal statutes made terrorism a criminal offense, common usage changed from a
broad meaning to one that specified terrorism as a political crime. The argument is that the state shapes meaning and public
discourse through law. Peircean semiotics and the semiotic philosophy of Russian linguist Vološinov provide a framework to
explore relationships among politics, law, and civil life. Applied to the events of September 11, 2001 such an analysis further
allows better understanding of certain interpreters of the September 11 attacks, notably Jean Baudrillard, Jacques Derrida,
and Jürgen Habermas. 相似文献

A simple and sensitive method is described for quantitative analysis of chlorpromazine in blood, serum, urine and tissue homogenate. The chlorpromazine cation radical produced by adding perchloric acid and 2,3-dichloro-5,6-dicyano-p-benzoquinone to the sample can be detected by the ESR method at room temperature. The sensitivity limit is 10 ng, that is, 20 μl of the solution containing 0.5 μg chlorpromazine/ml. The time needed for the measurement is within 10 min. The chlorpromazine radical thus produced is very stable; for example, 95% of the radical was observed after 24 h. The advantage of this method is discussed by comparing with the ordinary spectrophotometry which requires the purification of the sample. 相似文献

The remains of an unidentified female neonate were discovered in a field in central Missouri. Examination revealed bilateral absence of the parietal bones. A search of the literature describing similar defects suggests that the present case represents a unique condition, described here for the first time. 相似文献

With deeper integration into the global economy and expanded penetration by multinational firms and other nonChinese actors
following accession to the WTO, skills in bureaucratic entrepreneurship are not likely to be sufficient by themselves to bring
about China’s sustainable development. In today’s interdependent and highly competitive trade, economic-cooperation, and resource-limited
environment, sustainable development requires that subnational managers also possess transnational competence in collaborating
with, negotiating with, and transforming foreign counterparts. However, survey research among Chinese executives based in
Shanghai revealed that only a small proportion of the reporting current and future managers recognized the growing importance
for China of an interculturally competent workforce. Without increased attention to enhancing the transnational competence
of government and state-enterprise managers, peaceful and ecologically sound development will be difficult to sustain given
the demands of multinational production chains, global resource constraints, and the challenges involved in managing transnational
relations in the interest of China’s long-term economic progress.
