二战后的西欧为了突破美国的控制和苏联的威胁,同时为了恢复和发展经济,以应对日益激烈的国际竞争,逐渐走向经济一体化。统一大市场的形成促进了欧洲经济的发展,同时,它存在的问题不能忽视,成员国间的利益冲突还时常存在。  相似文献

第43届世界乒乓球锦标赛,中国选手邓亚萍、乔红等在面临欧亚外国选手及“海外兵团”有力挑战后,连闯数关,包揽世乒赛女子单打前三名,说明中国女队的技战术水平在世界乒坛仍占有较大优势,心理素质也日趋成熟,但中国女队也存在后备力量不理想,年轻选手心理素质不够稳定,技术风格不够凶狠等问题,需引起我们思想上足够的重视。  相似文献

We have studied the efficiency of research in the EU by a percentile-based citation approach that analyzes the distribution of country papers among the world papers. Going up in the citation scale, the frequency of papers from efficient countries increases while the frequency from inefficient countries decreases. In the percentile-based approach, this trend, which is uniform at any citation level, is measured by the ep index that equals the Ptop 1%/Ptop 10% ratio. By using the ep index we demonstrate that EU research on fast-evolving technological topics is less efficient than the world average and that the EU is far from being able to compete with the most advanced countries. The ep index also shows that the USA is well ahead of the EU in both fast- and slow-evolving technologies, which suggests that the advantage of the USA over the EU in innovation is due to low research efficiency in the EU. In accord with some previous studies, our results show that the European Commission’s ongoing claims about the excellence of EU research are based on a wrong diagnosis. The EU must focus its research policy on the improvement of its inefficient research. Otherwise, the future of Europeans is at risk.  相似文献

This study examined the inter-relationships of acculturative stressors experienced by Chinese international students. A sample of 463 Chinese students in six EU countries (UK, Germany, France, Netherlands, Spain and Belgium) responded to a web-based survey. The results showed that Chinese students in France suffered from bigger constraints in linguistic issues and dealing with life tasks than Chinese students in UK. Structural equation modeling (SEM) analysis revealed that language constraints and perceived cultural differences play a key role in influencing other stressors. The findings indicated that language constraints and perceived cultural differences accounted for 62% of the total variance of academic integration difficulty; language constraints accounted for 17% of the variance of problems in dealing with daily tasks; perceived cultural differences accounted for 56% of the variance of social integration difficulty; academic integration and problems in dealing with daily tasks explained 14% of the variance of homesickness.  相似文献

Environmental policy increasingly resorts to market-based instruments in order to meet sustainability objectives. The ‘carbon market’ instituted by the European Emissions Trading directive from 2003 is a canonical example, which has been described, and critiqued, as a delegation of policy objectives to market exchanges. In this paper, we examine the complex ways in which the operationalization of policy objectives and the organization of markets are intertwined, focusing on two other examples of European environmental regulation. The first one is the Integrated Pollution Prevention and Control directive from 1996, which defined the ‘best available techniques’ to curb emissions in air, water and soil. The second one is the Renewable Energy Directive from 2009, which introduced criteria for the definition of the sustainability of biofuels. Through the analysis of the design and implementation of these two directives, we identify a central concern for the coexistence of various objects, and various initiatives undertaken by European institutions, member states and private actors. We use the notion of coexistence to describe a European political and economic ordering that is inherently hybrid, and cannot be reduced to a mere delegation of policy objectives to the market, or a legal constraint imposed on all European actors. It grounds its political legitimacy and economic rationality on the distribution of roles and responsibilities across public and private actors, and on the ability to ‘keep things different’ according to local variabilities.  相似文献
