Sampling Methods and Sample Populations in Quantitative Mass Communication Research Studies: A 15-Year Census of Six Journals

This study evaluated the sampling methods and sample populations used in all U.S.-based survey and experimental mass communication studies published between 2000 and 2014 in six major journals (N = 1,173). Most studies used nonprobability samples, and more than half used student samples. Experiments used more nonprobability and student samples than surveys. Funded studies used more probability and nonstudent samples than nonfunded studies. Implications of results pertaining to population validity and interpretations of findings for mass communication research are discussed.     

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

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.     

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.     

中国传统文艺鉴赏理论范畴研究论评

近年来学术界关于中国传统文艺鉴赏理论的研究,从总体上看,带有仓促应对的色彩,存在不少弊端。要深化这一研究,最好是选择范畴体系的梳理作为突破口。这既由范畴本身在学科中的地位所决定的,也是由中国传统文艺鉴赏理论的独特表现形式所决定的。但是,在当前情况下,对中国传统文艺鉴赏理论进行范畴体系的梳理确实还存在不少困难。为此,研究者必须树立整体观念、历史观念、核心观念与现代观念。     

新时期对图书馆学研究方法的创新探索——学科外延与内涵深入的整合研究法

随着科学技术的发展,网络环境的变化,传统的图书馆学理论思想已经不适应当今的图书馆发展模式,原有的研究方法也不适用于新形势下的图书馆学研究。因此,图书馆学的研究方法必须突破传统的束缚,将图书馆学理论外延化和内涵深入性两方面进行有机整合研究,将是未来图书馆学理论研究的发展导向,这样才能更好地推动图书馆学的理论观点不断发展创新。     

数字资源保存的研究进展、热点与前沿

文章首先辨析了数字资源保存的概念,介绍了数字资源保存的发展史和国内外研究现状。然后利用CitespaceⅡ可视化分析工具和方法构建领域知识基础（指引文）的时间序列演化图谱和时区演化图谱,并结合绘制的领域发展趋势图,分析了数字资源保存的研究进展。同时利用CitespaceⅡ可视化分析工具和方法绘制术语与关键词的混合共现网络和引文共被引聚类知识图谱,识别出数字资源保存的研究热点U,并利用爆发词或突变词探测方法探测数字资源保存的研究前沿。最后针对图书情报与档案管理学科关注最多的研究热点——数字资源长期保存,从研究主题、最佳实践、保存周期、保存技术和方法、保存策略等几个重要方面解读数字资源长期保存的研究进展。     

TBL在《现代教育技术》课程教学中的准实验研究

在师范类专业《现代教育技术》公共课程的教学中,在对基于任务学（TBL）进行了前测一后测非对等控制组设计的准实验研究中,通过对实验数据的分析发现：在学生完成学科知识目标方面,TBL与传统讲授法没有显著差异;在学生完成学科技能（设计技能和制作技能）目标方面,TBL与讲授法存在显著差异;在完成调动学生兴趣,进行协作学习方面,两者呈现了显著差异。

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

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。
