Audience management,online turbulence and lurking in social networking services: A transactional process of stress perspective

In social networking services (SNSs), users’ unclear understanding of the large and invisible audience increases the chances of online turbulence, which is a key source of SNS-induced stress. This growing phenomenon has gained increasing attention in academia and industry due to the undesirable consequences for users and SNS platforms. In this study, we draw from the transactional model of stress to examine how audience management strategies impact online turbulence and lead to neglected unintended audience concern and lurking. We also investigate the role of self-monitoring as a stress inhibitor. We test our model with data collected from 301 SNS users. The results show that the four types of audience management strategies have different effects on online turbulence, which significantly impacts neglected unintended audience concern especially when users have high self-monitoring skills. We believe that this work contributes, both from scientific and practical standpoints, to the understanding of the interventions and stressful responses of online turbulence in SNSs.     

科学数据共享研究现状与展望

[目的/意义] 分析科学数据共享的研究现状及其发展趋势，为促进国内相关理论研究与实践进展提供参考。[方法/过程] 通过对国内外文献进行梳理和归纳，提炼出与科学数据共享研究相关的三大类主题：科学数据共享发展需求、科学数据管理共享模式与机制和科学数据服务共享度与服务效果，并构建科学数据共享管理分析框架，该框架体现上述三类主题之间的因果关联，强调科学数据共享管理与服务的合理面、重要度、关键性。[结果/结论] 国内外现有研究尚存不足，未来研究在加强实证研究、着眼管理机制完善的同时，还需注重共享服务模式的创新。

Reimagining Newsroom Collaboration: How Two European News Nonprofits Are Inviting Citizens In

ABSTRACT

News nonprofits in the U.S. have been proliferating over 15 years as a way of addressing troubles in the business model for news. For these newsrooms, collaboration, with each other and with mainstream news, has emerged as a key way to build readership and attain relevance in a crowded media space. Still, past research has told us that the strong connection to mainstream news has constrained these organizations’ critique of journalism. In Europe, nonprofit news remains nascent and represents a response to declining trust in and engagement with journalism, and rising populism across the continent. Against this very different context, this study examines two players at the forefront of the European news nonprofit movement. It demonstrates the path dependency inherent in the origins of these organizations: In Europe, they are a response to a different societal change, and thus developed rather differently than did their peers in the United States, with a focus on redefining the idea of collaboration and the role of their audiences by seeing citizens as collaborators, both in the creation and in the dissemination of news. By seeing citizens as collaborators, not just readers, they work to empower and build news audiences as well as participants.     

新时代我国少数民族地区体育公共服务分层治理研究

采用文献资料法等研究方法对新时代我国少数民族地区体育公共服务分层治理进行研究，旨在为提高我国少数民族地区体育公共服务质量和建设体育强国提供建议。研究认为，少数民族地区体育公共服务分层治理是基于我国社会分层的现状以及各阶层体育需求和参与特征存在的差异而采取的差异性治理方式，分层治理有"因层制宜"的意蕴，有利于促进我国少数民族地区体育公共服务均等化和改变少数民族地区体育公共服务"供给不足"和"供非所需"的困境。现阶段我国少数民族地区体育公共服务分层治理的思路包括明确少数民族地区体育公共服务分层治理主体责任、完善少数民族地区体育公共服务分层治理资金保障机制、积极探索少数民族地区体育公共服务分层供给方式、构建少数民族地区体育公共服务分层治理协商机制、建立少数民族地区体育公共服务分层供给绩效评价体系。     

Professional knowledge or motivation? Investigating the role of teachers’ expertise on the quality of technology-enhanced lesson plans

In an expertise study with 94 mathematics teachers varying in their relative teacher expertise (i.e., student teachers, trainee teachers, in-service teachers), we examined effects of teachers' professional knowledge and motivational beliefs on their ability to integrate technology within a lesson plan scenario. Therefore, we assessed teachers' professional knowledge (i.e., content knowledge, pedagogical content knowledge, technological knowledge), and their motivational beliefs (i.e., self-efficacy, utility-value). Furthermore, teachers were asked to develop a lesson plan for introducing the Pythagorean theorem to secondary students. Lesson plans by advanced teachers (i.e., trainee teachers, in-service teachers) comprised higher levels of instructional quality and technology exploitation than the ones of novice teachers (i.e., pre-service teachers). The effect of expertise was mediated by teachers' perceived utility-value of educational technology, but not by their professional knowledge. These findings suggest that teachers’ motivational beliefs play a crucial role for effectively applying technology in mathematics instruction.     

一种基于图卷积自编码模型的多维度学科知识网络融合方法

[目的/意义] 针对包含单一类型知识单元的知识网络难以全面反映学科知识结构的问题，提出一种从多维度进行知识网络结构融合的方法，为学科领域知识结构挖掘提供借鉴。[方法/过程] 利用LDA及TF-IDF方法抽取学科知识单元，然后运用语义相似度和关键词共现分析方法构建3个学科知识子网络：主题网络、关键词网络和实体网络，并采用空间节点传递对齐方法对齐子网络节点，接着设计基于图卷积操作的自编码模型对知识节点进行表示，最后通过计算余弦相似度重构学科知识网络。[结果/结论] 实验部分以人工智能领域为例，构建融合主题、关键词和实体的学科知识网络并展开分析，实验结果表明，本文所提方法能有效地揭示学科领域研究内容和知识结构，为学科知识发现与组织研究提供有益参考。
