Research universities on the ResearchGate social networking site: An examination of institutional differences,research activity level,and social networks formed     

Weiwei Yan  Yin Zhang 《Journal of Informetrics》2018,12(1):385-400

As one of the largest active academic social networking sites, ResearchGate (RG) has been utilized by scholars to share publications, seek collaborators, communicate work in progress, and build scholarly reputation. This study collects data from RG users from 61 U.S. research universities at different research activity levels, as categorized by the Carnegie Classification of Institutions of Higher Education, to examine the impact of institutional differences on RG reputational metrics. The results confirm that RG is a research-oriented academic social networking site that closely and realistically mirrors the research activity level of institutions. With an increase in the research activity level of a university, its affiliated RG users tend to have higher RG scores, more publications and citations, and more profile views and followers, while the average number of reads of their publications and followees tend to be lower and fluctuant. In addition, RG users primarily follow others from institutions of a higher research activity level, forming virtual social networks centered around esteemed institutions. The study suggests academic social networks can serve as indicators in evaluation of research activities among research institutions, and such sites can be helpful and credible for acquiring resources, keeping informed about research, and promoting academic influence.  相似文献   

A comparison of two approaches for measuring interdisciplinary research output: The disciplinary diversity of authors vs the disciplinary diversity of the reference list     

Giovanni Abramo  Ciriaco Andrea D’Angelo  Lin Zhang 《Journal of Informetrics》2018,12(4):1182-1193

This study investigates the convergence of two bibliometric approaches to the measurement of interdisciplinary research: one based on analyzing disciplinary diversity in the reference list of publications, the other based on the disciplinary diversity of authors of publications. In particular we measure the variety, balance, disparity and integrated diversity index of, respectively, single-author, multi-author single-field, and multi-author multi-field publications. We find that, in general, the diversity of the reference list grows with the number of fields reflected in a paper’s authors’ list and, to a lesser extent, with the number of authors being equal the number of fields. Further, we find that when fields belonging to different disciplines are reflected in the authors’ list, the disparity in the reference list is higher than in the case of fields belonging to the same discipline. However, this general tendency varies across disciplines, and noticeable exceptions are found at individual paper level.  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

旅游景观形象设计审美性原则探讨     

黄艺农 《湖南师范大学社会科学学报》2003,32(3):116-120

旅游景现形象设计必须遵守三项审美性原则：一为形象性原则，即使形象具有具体性、生动性和可感性，从而具有丰富深刻的化价值和审美价值。二为悦情性原则，即按照美的规律使形象具有“美”这种本质属性，能激起人们的高尚情感愉悦。三为可持续发展原则，即使美的景现形象达到既要满足当代人需求又不危及后代人满足其需求的发展。  相似文献

基于学习共同体的中小学生学习心理机制及有效教学策略     

黄爱玲  宋艳丽 《当代教育与文化》2019,11(6):60-65

学习共同体的学习方式有别于传统的教师主讲式的课堂授课形式。学习共同体特别强调"师-生"之间,"生-生"之间缔结一个相互联系、相互制约、彼此促进的共同体来完成学生的学习活动。基于学习共同体的中小学生学习心理机制是一种主动建构、信息加工的过程,即:"1.输入信息、注意保持、认知观念;2.加工信息、内化知识、建构系统;3.改组经验、解决问题、生成能力"。学习共同体旨在教师引导下,让学生通过自主探究、小组讨论、合作分享、获得知识、生成能力。教师实施有效的教学策略,充分发挥学习共同体的功能,会促进培养中小学生的核心素养,提升学生分析问题解决问题能力。  相似文献
