曹树金  王志红 《图书情报工作》2018,62(8):74-83

[目的/意义] 针对已有虚拟社区知识共享意愿与行为影响因素实证研究结果之间的不一致问题,对该领域相关实证研究加以梳理和再分析。[方法/过程] 利用元分析方法,通过系统收集和虚拟社区知识共享意愿与行为相关的实证研究文献,梳理和识别影响知识共享意愿与行为的关键因素,并通过异质性检验和分组分析,探索不同研究之间存在不一致性的原因,从而检验调节变量的影响。[结果/结论] 研究发现,对知识共享意愿与行为具有显著正向影响的因素分别有10个、14个,其中利他主义和知识共享态度对知识共享意愿的影响最大,结果期望、共同语言、主观规范和身份认同是影响知识共享行为最显著的变量。同时,研究识别了社区类型和研究情境是不同研究异质性的部分来源,具有一定的调节效应。通过梳理和识别知识共享意愿与行为的影响因素和调节因素,可为虚拟社区管理者提供参考,为该领域后续研究提供更好的理论基础。  相似文献

Evaluation of Internet Information Sources by High School Students in Ghana     

Philip Kwaku Kankam 《International Information and Library Review》2018,50(2):88-93

The Internet clearly presents the opportunity for students to expand their knowledge at a fast pace, since they are able to access enormous amount of information. However, accessing the Internet also has its downside since not all information is of good quality. The study explored how 12th grade students at a high school in Ghana evaluated online information sources. These students and the head of the Information Communication Technology department respond to self-administered questionnaires and a semi-structured interview, respectively. The study found that most of the high school students did some kind of an evaluation of online information sources, however, they were not applying the right criteria. The study further revealed that students were not introduced to evaluation criteria at school and this had contributed to the gap in their evaluation competencies.  相似文献   

Tools and Principles for Effective Online Library Instruction: Andragogy and Undergraduates     

Kathy A. Watts 《Journal of Library & Information Services in Distance Learning》2018,12(1-2):49-55

The library literature evaluating the efficacy of online tutorial methods and delivery tools is a valuable resource for librarians looking for information to inform their choices for developing asynchronous online instruction. This literature, however, examines a wide variety of delivery tools, methods, and student populations. As a result, it is difficult to draw definitive conclusions about any one tutorial tool or method. This article compares selected research and concludes that the consensus in the literature suggests that applying adult learning principles to library tutorials has a larger impact on effective online instruction than the individual tool.  相似文献   

Two Thousand Students,One Librarian: Balancing Depth and Breadth of Library Instruction for Online Graduate Students     

Lindley Homol 《Journal of Library & Information Services in Distance Learning》2018,12(3-4):250-258

Many librarians struggle with how to balance scalable instructional offerings with more personalized instruction for online students—scale tends to come at the cost of personalization and vice versa. This paper will discuss three methods for connecting with online students that range from one-to-one personalization to widely scalable instruction: individual consultations, scaffolded instructional webinars, and asynchronous video tutorials. The student engagement with each type of instruction will be discussed, with ideas for future directions provided.  相似文献

Reactivity without legitimacy? Online consumer reviews in the restaurant industry     

Jean-Samuel Beuscart  Kevin Mellet 《Journal of Cultural Economy》2016,9(5):458-475

In recent years, web sites where individual consumers can rate and review goods and services have mushroomed all over the Internet. Restaurants are particularly affected by online reviewing. If the impact of online consumer reviews (OCRs) on the demand side of markets is now well understood and measured, few studies examine the reception of this new evaluation method by those who are assessed. Based on interviews with French restaurant managers, our research shows that OCRs systems reconfigure relations of accountability in the restaurant industry. We use the notion of reactivity to describe the mechanisms through which the new evaluation system transforms the activity of restaurants. We also examine the affects surrounding the reception of ratings and reviews by restaurant managers and the moral criteria that accompany their discourses on online reviews. Many restaurants consider online reviews as a brutal and hypocritical mode of judgment. The judgment produced by online ratings and reviews is not easily borne by restaurant managers, because it challenges the conventions of quality they had previously internalized as legitimate, that is, those produced by professional experts. We interpret this ambivalent reception as the unfinished movement of transforming a performative reputation device into a legitimate evaluation institution.  相似文献   

Press Credentials and Hybrid Boundary Zones: The Case of WorldNetDaily and the Standing Committee of Correspondents     

Jordan M. Foley 《Journalism Practice》2020,14(8):933-953

ABSTRACT

Press credentialing practices are a vital, yet understudied site of scholarly research on journalistic norms and practices. Press credentialing not only structures internal professional hierarchies, but they also signify the boundaries of the journalistic field itself. This paper explores the legal and theoretical implications of press credentialing to cover the United States Congress, drawing on the concepts of boundary work and journalistic authority to demonstrate the material impact of the space between fields on professional legitimation in journalism. Using WorldNetDaily (WND) as a case study, I argue that the Standing Committee of Correspondents (SCC) occupies a hybrid boundary zone between the journalistic and political fields, generating a unique tension in First Amendment jurisprudence that places journalists in a paradoxical role as both the professional embodiments of free speech and its constitutional steward. The resulting jurisdictional conflict between the SCC and WND extends the relational model of journalistic authority by articulating how journalist-state relations can fundamentally augment the process of legitimation at its fuzzy boundaries. The relevance and implications for press credentialing practices in the digital age are discussed.  相似文献
