The goal of this paper is to analyze the impact the EU has had on Czech women’s groups since the 1990s. Drawing on both Europeanization and social movement theories, the first section defines the theoretical framework of the paper. The second section is focused on the impact of changes in the funding of women’s groups which, since the end of the 1990s, have relied more than before on European funding. The third section analyzes the shift in the political context and the domestic political opportunity structure in the Czech Republic that has occurred in connection with the accession process. The fourth section analyzes transnational cooperation for which new opportunities have appeared with the EU’s eastward expansion. The paper concludes by summarizing its main findings.  相似文献

Now that racism has been officially recognized in Brazil, and some universities have adopted affirmative-action admission policies, measures of the magnitude of racial inequality and analyses that identify the factors associated with changes in racial disparities over time assume particular relevance to the conduct of public debate. This study uses census data from 1950 to 2000 to estimate the probability of death in the early years of life, a robust indicator of the standard of living among the white and Afro-Brazilian populations. Associated estimates of the average number of years of life expectancy at birth show that the 6.6-year advantage that the white population enjoyed in the 1950s remained virtually unchanged throughout the second half of the twentieth century, despite the significant improvements that accrued to both racial groups. The application of multivariate techniques to samples selected from the 1960, 1980, and 2000 census enumerations further shows that, controlling for key determinants of child survival, the white mortality advantage persisted and even increased somewhat in 2000. The article discusses evidence of continued racial inequality during an era of deep transformation in social structure, with reference to the challenges of skin color classification in a multiracial society and the evolution of debates about color, class, and discrimination in Brazil.  相似文献

In the light of the increasing political influence on German universities (amongst others, the excellence initiative) with effects on the selection of top positions, this article examines the appointment of chairs (department heads) in a “small” surgical specialty during the last 30 years. Following the delineation of official indicators of competence (inclusion criteria) within an appointment procedure, it can be shown that a broad distribution of institutions and persons that meet these criteria exists. The empirical examination of the actually successful occupations shows that closure mechanisms play a role because the successful candidates stem from no more than 10 out of 34 clinical departments. The monetary capital in terms of third-party funds is the most important allocation criterion, but cannot sufficiently explain the way appointments take place. As there are candidates who in formal terms are in a wide measure equally qualified, and a consequential uncertainty of the basis of decision within an appointment procedure, the derivation of the candidate in terms of a personal relationship to a chair holder (department head) from whose clinic he applies and who acts as a patron, proves to be the decisive distinction following the examination of all inclusion criteria. This results in a reproduction of the chair holders (department heads) largely from the same clinical departments and the formation of an academic caste system. In perspective, this cartel-like closure appears to be getting increasingly worse.  相似文献

It has long been presumed in the literature that consolidated democracies that face serious external threats or are NATO-aligned should feature strong, civilian control institutions and personnel. This study of Israel, India, Taiwan, Spain and Poland reveals otherwise. Utilizing biographical data compiled by the authors, we researched civilian personnel within each country’s defence ministry – the organizational hub of civil-military relations. Rather than finding evidence of strong civilian control, what we found instead were ministries with serious deficiencies: they did not have effective power; they failed to engage in defence planning or provide strategic guidance to the armed forces; they were led by military personnel and staffed by civilian employees not properly qualified to handle defence affairs. To explain these discrepancies, we argue that long-standing deficits in civilian expertise spur the delegation of ministerial defence positions to more knowledgeable officers. Comparisons are made with benchmark states that have achieved civilian ministerial control.  相似文献

The joint establishment of One Belt One Road is a practice of international cooperation initiated by China and actively participated by other countries. One of the important issues is how to ensure sustainable common security, and what kind of geopolitical theory should be employed for guidance. Traditional geopolitical theories, such as sea power theory, land power theory and Rimland theory, mainly serve for the fi ght for geopolitical hegemony or military strategy. They are in sharp contrast with the goal of One Belt One Road, which is of mutual interest and a win-win situation. However, One Belt One Road is still regarded by some countries from the traditional geopolitical perspective. To equip One Belt One Road with new geopolitical concepts, the author hereby proposes the theory of land-ocean peaceful cooperation, which is a non-alliance network community of common interests, security and destiny. This community would be established for mutual benefi ts, between ocean countries and land countries, among ocean countries and among land countries. It could help policy communication among participant countries of One Belt One Road, and the establishment of an open net-like system of peaceful operation and common development. The theory of land-ocean peaceful cooperation of sustainable security, together with the practice of international cooperation of One Belt One Road, will undoubtedly break through the vicious cycle of the Eurasian geographical fi ght and confrontation between sea powers and land powers illustrated by the traditional geopolitics.  相似文献

Recreational use of the potent synthetic opioid 3,4‐ dichloro‐N‐(2‐(dimethylamino)cyclohexyl)‐N‐methylbenzamide (U‐47700) is rising, accompanied by increasingly frequent cases of serious intoxication. This article reports a case of near‐fatal U‐47700 intoxication. A man was found unconscious (with drug powder residues). After 40 h in hospital (including 12 h of supported ventilation), he recovered and was discharged. Liquid chromatography/high‐resolution mass spectrometry (LC/HRMS) or gas chromatography/mass spectrometry (GC/MS) were used to detect and quantify substances in powders, serum and urine. Powders contained U‐47700 and two synthetic cannabinoids. Serum and urine were positive for U‐47700 (351.0 ng/mL), citalopram (<LOQ), tetrahydrocannabinol (THC: 3.3 ng/mL), midazolam (<LOQ) and a novel benzodiazepine, clonazolam (6.8 ng/mL) and their metabolites but negative for synthetic cannabinoids. If potent synthetic opioids become cheaper and more easily obtainable than their classical counterparts (e.g., heroin), they will inevitably replace them and users may be exposed to elevated risks of addiction and overdose.  相似文献
