The IR Has Two Faces: Positioning Institutional Repositories for Success     

John Novak  Annette Day 《New Review of Academic Librarianship》2018,24(2):157-174

This article describes the ongoing efforts at University of Nevada, Las Vegas (UNLV) Libraries to evolve the role of the institutional repository (IR) and to effectively position it within the context of the Libraries’ collections, research support, and scholarly communication services. A major component of this process is re-examining the fundamental aims of the IR and aligning it to the Libraries and the campus strategic goals. The authors situate UNLV Libraries’ experience within the context of the current literature to provide background and reasoning for our decision to pursue two, at times conflicting, aims for the IR: one for scholarly communication and another for research administration.  相似文献   

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

Alonso Rodríguez-Navarro  Ricardo Brito 《Journal of Informetrics》2018,12(3):718-731

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.  相似文献   

基于关联规则的李娜、莎拉波娃相持阶段战术特征比较研究     

楼恒阳  梁名洋  刘文明 《北京体育大学学报》2016,39(10):141-145

摘要：基于关联规则，运用文献资料法、录像观察法、数理统计法等方法对李娜与莎拉波娃以及二人与其他世界优秀女子运动员之间18场硬地单打比赛“相持阶段”战术行为进行了研究，对比分析了两位选手“相持阶段”战术特征，目的是为中国乃至亚洲继续培养优秀的女子单打网球选手提供经验与参考。结论与建议：通过对李娜和莎拉波娃相持阶段的对比研究的结果可以为中国女子单打网球运动员提供经验借鉴。相持阶段应采取大范围调动对手跑动策略，增加在底线斜线相持时候的变线能力。在底线相持中，更应该注重增加正手击球的攻击性。在主动进攻时，应减少中路回球的非受迫性失误概率。  相似文献   

The Impact of an Erasmus Placement in Students’ Perception of their Intercultural Communicative Competence     

Ramiro Durán Martínez  Gloria Gutiérrez  Fernando Beltrán Llavador  Fernando Martínez Abad 《Journal of Intercultural Communication Research》2016,45(4):338-354

Pre- and post-questionnaires answered by UK Nottingham Trent University (NTU) and Spain’s University of Salamanca (USAL) students on their placement abroad support a comparative analysis of its impact on their intercultural communicative competence, comprising the awareness, attitude, skills and knowledge dimensions. NTU students started their placements with better results in them all. Yet, while both groups completed their stay with a similarly increased awareness, the knowledge and skills of the USAL group matched the results of NTU students and, whereas the scores of the attitude dimension towards the host country of NTU students did not increase significantly, those of USAL students decreased.  相似文献
