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

The world has been turned upside down by a global health emergency caused by the Covid-19. Given the high contagiousness of the virus and the need to contain its spread, social distancing rules, self-isolation policies, and geographical lockdowns have been enforced globally. Over the pandemic emergency the majority of the planned in-person meetings and congresses of national and international anatomical societies have been postponed or canceled. It is unclear what the future holds, but times of crisis often present possibilities for re-thinking old ways to achieve a more critical approach. It has become increasingly clear that traditional in-person congress formats of scientific societies need to be reevaluated. Over the past year and a half, two types of congressional modalities have been trialed to address the challenge of the pandemic as far as scientific meetings are concerned: the fully virtual congress, in which case the conference program is live streamed to all of the attendees, and the hybrid congress, in which case some of the attendees physically participate at the congress's venue while others interact via a virtual platform. The current study set out to investigate the technical difficulties, social challenges, costs and sustainability, logistics and management issues linked to holding various types of congresses in the post-Covid world. Anatomical societies throughout the world are actively striving to reshape their response to the current global emergency and to uncover new types of conference modalities in the effort to keep scientific exchange alive and flourishing in the post-Covid era. 相似文献

尽管宜宾市第三次全国文物普查全面而仔细,"全市乡村普查到达率均达到100%",但笔者对宜宾市戏曲文物调查时,又查出九座古戏楼,它们分别是江安县底蓬镇古戏楼、江安县蟠龙镇古戏楼、江安县桐梓镇禹王宫古戏楼、江安县夕佳山民居古戏楼、长宁县桃坪乡玉皇楼古戏楼、长宁县梅硐镇余家祠堂古戏楼、珙县洛表镇何家大院两座古戏楼、长宁县老翁镇文昌宫古戏楼。以上戏楼具有丰富的历史文化价值,笔者实地测量了相关数据,并采访相关人士发现了因把握文物的标准不同、建筑保存现状很差等原因造成这九座戏楼被普查遗漏了。 相似文献

微博是90后大学生进行政治意识表达的主要载体,大学生的政治意识在某种程度上影响着社会大众的思想意识。在微博的影响下,大学生政治意识的主流虽然是积极、健康、向上的,但也出现了政治冷漠,盲目轻信甚至是群体极化的现象。因此,政府应该加强微博立法,高校应开设公共微博,培养一批意见领袖,而大学生也要努力提高自己的微博素养,才能保证微博上政治意识表达的有序运行。 相似文献

We first report discovery of the spinel-garnet-orthopyroxene granulite with pure CO2 fluid inclusions from the Fuyun region of the late Paleozoic Altay orogenic belt in Central Asia, NW China. The rock is characterized by an assemblage of garnet, orthopyroxene, spinel, cordierite, biotite, plagioclase and quartz. Symplectites of orthopyroxene and spinel, and orthopyroxene and cordierite indicate decompression under UHT conditions. Mineral chemistry shows that the or-thopyroxenes have high XMg and A12O3 contents (up to 9.23 wt%). Biotites are enriched in TiO2 and XMg and are stable under granulite facies conditions. The garnet and quartz from the rock carry monophase fluid inclusions which show peak melting temperatures of around -56.7℃, indicating a pure CO2 species being presented during the ultrahigh-T metamorphism in the Altay orogenic belt. The inclusions homogenize into a liquid phase at temperatures around 15.3-23.8℃ translating into CO2 densities of the order of 0.86-0.88 g/cm3. Based on prelim 相似文献
