开放式创新研究的演化路径和热点领域分析——基于科学知识图谱视角

以Web of Science数据库中收录的开放式创新文献为研究对象,借助Citespace II软件进行知识图谱分析,分别制作了时空分布、文献共引和关键词共现知识图谱,进而探究了开放式创新研究的分布状况、变化趋势和热点领域。研究表明:(1)英美两国学者引领了开放式创新研究,我国学者在该领域的研究处于稳步提升阶段,但能够密切跟踪国际前沿;(2)开放式创新研究的发展趋势是研究对象日趋多样化、实证研究取代案例研究成为主要研究方法以及基于网络社区的创新交互逐步取代企业实体之间的技术交易和合作研发成为研究主流;(3)开放式创新研究的四个热点领域是开放式创新模式与企业绩效的关系、基于创新网络的研发合作和技术交易、开放式创新知识治理和用户参与的开放式创新实践应用。

Teacher–Student Relationship Quality and Children's Bullying Experiences With Peers: Reflecting on the Mesosystem

Drawing from social–ecological systems theory, the authors argue that -current research on childhood bullying would benefit from analyses that consider the -mesosystem—specifically, how teacher–student relationships can influence -children's bullying experiences. The authors provide two theoretical conceptions for how children's peer interactions are implicitly shaped by teacher–student relationship quality: attachment and social referral. Implications for practice, with an emphasis on developing teachers' social–emotional competencies to strengthen positive teacher–student relationships, are proposed.     

“自我”与“自尊”——从心理学角度浅析《红与黑》中的于连

自尊心便是—个人的价值判断,把对自己的价值判断应用于与他人,与社会的交往之中,便形成了“自我”的概念。《红与黑》的社会背景是法国大革命前夕。当时的于连,努力地想实现自己的价值判断,却又处处碰壁。这只缘于他不甘心自己的平民出身,并在当时社会的拿破仑模式的英雄主义的影响下,一心要提高自己的价值,一心要爬到那个与平民阶层处处不相容的上层社会之中,到头来也只满足了他冲锋陷阵的虚荣,成就了他英雄主义的“自尊”……

American Isolationism and The Political Evolution of Journalist-Turned-US Senator Gerald P. Nye

This article outlines the rise of the radical agrarian Nonpartisan League (NPL) press in North Dakota, focusing on NPL editor Gerald P. Nye, who took his Prairie-based populist platform and constituents' post-World War I anti-British sentiments to Washington, DC. There he effectively opposed active US participation in European and Asian wars as a US senator from 1925 to 1941. The article explores the intersection of journalism and politics through the development of Nye's isolationist ideology as a rural newspaper editor and his rise as a powerful political ideologue and advocate in the Senate.     

Are Library Science Programs Preparing New Librarians? Creating a Sustainable and Vibrant Librarian Community

Recent studies show a growing sense of frustration for new library and information science (LIS) graduates who struggle to gain employment, as well as for hiring libraries who find the skills of entry-level employee candidates to be lacking. This study endeavors to discover the origins of this troubling juxtaposition by examining the perceptions of recent LIS graduates. The researchers administered a large-scale survey with over 575 respondents, analyzed and coded the data, and compared codes using a Cohen's kappa calculation. The responses indicate that LIS graduates feel that their LIS education would have been more valuable had it given them more opportunities to gain experience, more courses in technology and instruction, more guidance in which courses to take, and more mentoring opportunities with practicing information professionals.
