Technological research in the EU is less efficient than the world average. EU research policy risks Europeans’ future

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 e_p index that equals the P_{top 1%}/P_{top 10%} ratio. By using the e_p 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 e_p 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.     

萨马兰奇改革传统奥运模式的历史必然性及其哲学思辨

为了揭示萨马兰奇改革传统奥运会模式的历史必然性及剖析其思想底蕴。运用社会结构分型理论、一般系统论、存在进化理论和信仰理论对萨马兰奇变革传统奥运模式的历史必然性进行了思辨。认为：萨马兰奇对奥运传统模式的改革是奥林匹克运动发展中的一场革命。它适应了社会生产力的新变化对奥林匹克运动提出的新要求;它反映了奥运模式是主、客观内在统一的认识论规律,它区别了信仰和主义;它折射了开放性的动态思维的光辉。

Global convergence or national variation? Examining national patterns of classroom instructional practices

The world culture framework posits a convergence in the organisation of education across the world. On the other hand, scholars observing teaching practices inside classrooms find significant variation among nations and regions of the world. This study examined the global change patterns of classroom practices at the between- and within-country levels, drawing on teacher reports from the Trends in Mathematics and Science Study. Results indicate clear between-country convergence toward more student-centred and conceptual instruction. But a nation’s degree of conformity or resistance to this model was contingent upon other nation-specific factors, including centralised curriculum control or world regional location.
