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.     

大学生心理健康现状调查分析及对策研究——以贵阳学院为例

通过对贵阳学院2000余名学生进行的各种心理健康量表测量的调查显示,大学生的心理健康状况总体上是比较好的,但是有一定数量的大学生因为不同原因存在着不同程度的心理问题。而且,许多心理问题是因为一些思想问题没有得到很好的解决,长期累积而导致其产生的。在对大学生心理健康状况进行分析的基础上,进行了相应的对策研究。     

欧盟贯通科学仪器创新价值链的项目资助模式研究及启示

科学仪器是科学研究不可或缺的工具,是推进高水平自立自强的重要基石和保障。重大科技基础设施研发建设催生诸多具有产业应用前景的科学仪器及相关技术,但转移转化尚任重道远。欧盟基于“开放科学、开放创新与向世界开放”理念设立ATTRACT项目,尝试加速推进重大科技基础设施探测和成像相关的实验技术产品化与市场化,构建基于科学仪器创新价值链的创新生态系统。文章围绕国内科学仪器项目组织现状与管理特点,深入剖析ATTRACT项目的组织管理模式,以期为我国加速重大科技基础设施先进技术转化,优化科学仪器创新资源配置,突破高端科学仪器研发与转化瓶颈提供支撑和参考。     

图书在线评论与销量关系实证研究述评

近十年来,国内外学者在不断探索在线评论的测度和文本挖掘方法的基础上,对在线评论与销售绩效间的关系进行了大量实证研究,研究结论包括正相关、负相关、不显著等多种形态关系.这表明,在线评论对销量的影响不仅取决于在线评论维度的选取与测度等自身因素,还取决于在线评论的产品类别、来源平台差异、文化语境等情境因素.由于在线评论分析的领域性较明显,本文仅以图书领域为例,对国内外已有的图书在线评论与销量关系的实证研究进行系统归纳和总结,旨在为研究者进行规范的实证研究提供思路.

我们从邻国的新村运动中学到了什么?——韩、日两国乡村振兴运动中的教育功用透视

韩、日两国都十分重视教育在乡村振兴中的作用,通过正规和非正规两种教育形式提高乡民素质、改变乡民观念并增强其伦理道德水平和国民凝聚力、建设力。我国乡村振兴战略实施可借鉴韩日做法:以政府为主导实行财政、立法双轮驱动,切实加强乡村振兴"硬建设",改善乡村基础设施面貌,因地制宜发展乡村特色农产业,提高乡民物质生产水平;以教育为主导实行普通教育、职业教育双轮驱动,切实加强乡村振兴"软建设",强化乡民伦理道德教育,培养新型乡民,提升乡民精神生活境界。

The relative age effect on physical fitness in preschool children

ABSTRACT

The aim of the present study was to investigate the existence of a relative age effect (RAE) on physical fitness of preschoolers. Anthropometry and physical fitness were assessed in 3147 children (3–5 years old) using the PREFIT battery. Based on the birth year, participants were divided into 3year groups (3-, 4- and 5-years). Within each year group, 4quarter groups were created: quarter 1, preschoolers born from January to March; quarter 2, from April to June; quarter 3, from July to September; quarter 4, from October to December. The MANCOVA analysis revealed a main effect of year group (Wilks’ λ = 0.383; F_10,5996 = 369.64; p < 0.001, η_p ² = 0.381) and of quarter (Wilks’ λ = 0.874; F_15,8276.6 = 27.67; p < 0.001; η_p ² = 0.044) over the whole battery of tests. To the best of our knowledge, this is the first study to report the existence of RAE at the preschool stage. In general, performance improved as the relative age increased (i.e., those born in quarter 1 performed better than those in the other quarters). Individualization strategies should be addressed within the same academic year not only in elementary or secondary years but also in preschoolers.
