The more multidisciplinary the better? – The prevalence and interdisciplinarity of research collaborations in multidisciplinary institutions

Scientific research is increasingly relying on collaborations to address complex real-world problems. Many researchers, policymakers, and administrators consider a multidisciplinary environment an important factor for fostering research collaborations, especially interdisciplinary ones that involve researchers from different disciplines. However, it remains unknown whether a higher level of multidisciplinarity within an academic institution is associated with internal collaborations that are more prevalent and more interdisciplinary. Analyzing 90,000 publications by 2500 faculty members in over 100 academic institutions from three multidisciplinary areas, information, public policy, and neuroscience, we investigated the connection between multidisciplinarity and research collaborations. Based on social network analysis and text mining, our analysis suggests that more multidisciplinary institutions are not necessarily more collaborative, although they do feature collaborations that are more interdisciplinary. Our findings provide implications for academic administrators and policymakers to promote research collaborations and interdisciplinarity in academic institutions.     

Proximal advantage in knowledge diffusion: The time dimension

This paper intends to explore the impact of geographic proximity on the diffusion of knowledge in the form of publication citations, and argues that codified knowledge is transmitted faster in proximity and is subject to similar geographic constraints as tacit knowledge. The geographic proximity advantage would be particularly relevant in the early stage of dissemination. We collected three sets of research articles published in 1990, 2000 and 2010 and compared the longitudinal citations they received domestically and from abroad. The study found that domestic citations accumulate faster and reach their peak much earlier than foreign citations, and the difference is most evident in the first few years after publication. The result shows that geographic proximity does play a role in the speed of knowledge diffusion and points to the network effect for citations. Those located closer to the knowledge origin would be exposed and react to publications faster due to the additional opportunities of research exchange and network.     

The density of social networks moderates effects of intergroup contact

This study tests how the density of the social network in which intergroup contact takes place might affect the extent to which contact improves intergroup attitudes. Having contact with more outgroup members in dense social networks, in which everybody knows each other, may reinforce contact's positive effect. In this case, outgroup contact is shared with ingroup members, which suggests positive ingroup norms toward the outgroup. Alternatively, more contact in denser networks may improve intergroup attitudes less because density may increase subtyping or reduce the salience of ethnic group memberships. These competing hypotheses are tested among white American adults in a nonprobability online sample (N = 305) and in a representative national sample (N = 1270). In both studies, contact is associated with more positive attitudes toward racial outgroups but the positive contact effect is weakened if that contact takes place in a denser social network.     

基于BP神经网络的大学生实践教学效果评价研究

实践教学是高等学校教学工作的重要组成部分,其中实践教学效果评价是保障高等学校实践教学质量的重要环节。针对高校大学生项目实践教学效果评价需求,构建项目实践教学效果评价指标体系,在此基础上设计调查问卷,利用网络问卷收集评价原始数据,通过Python进行数据预处理,并采用BP神经网络对某高校大学生项目实践教学效果实施评价,结果表明,该方法对于高校实践教学效果评价具有较强的实用性。     

论网络环境下的高校思想政治工作创新

网络条件下思想政治工作与传统思想政治工作相比，具有民主化、信息化、社会化等时代特征。现代网络技术为当代高校思想政治工作带来发展机遇的同时，也带来了严重的负面影响。因此，必须从如下几个方面创新高校思想政治工作机制：理顺管理体制；加强网络研究，探索传播规律；强化法制意识，规范网上行为；采用新的工作内容、方法和技术。     

网络文学非法转载治理

网络文学非法转载有别于纸质图书盗版,它是一种特殊的著作权侵权形式,具有快捷性、隐蔽性和影响广泛性等特点,侵害了作者及其授权刊载网站的信息网络传播权,对网络文学产业的健康发展造成了严重损害。网络文学非法转载的盛行同违法成本较低和免费网络消费观有较大关系,因此,要营造健康的网络文学传播发展环境,需要构建适宜的治理机制,增强作者及其授权网站的维权意识和维权能力,加大对非法转载的责任追究力度,建立有利于遏制非法转载的追究程序。     

对新时期“网络德育”工作的思考

科技的进步使人类进入信息社会，网络开始普及，大学生是网络的受众主体之一，给高校德育工作带来了挑战与机遇，高校德育工作者应该积极行动起来，做好调查研究，努力探索与开拓网络德育工作的新局面。     

网络百科全书刍议

网络百科全书是传统百科全书以互联网为载体并与计算机技术相结合的百科工具书,它仍不能离开百科全书的原本性质,而成为信息搜索引擎一类的工具。网络百科全书的最大优势是借助互联网和IT技术可以实时修订,随时更新和能创造出知识的多样表达方式。交互式多媒体百科全书,可能是创制网络百科全书的重要参考。

论网络时代高校思想政治工作

网络时代,高校师生的学习方式和生活方式发生了深刻变化。互联网在促进教育发展和人才培养的同时,对学生的消极影响不容忽视。要多方面加强思想政治工作,如开辟网上“思想政治教育课堂”、设置“网上德育阵地”、建立信息监控等。
