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

A post-American world? Assessing the cognitive and attitudinal impacts of challenges to American exceptionalism     

Jason Gilmore  Charles Rowling 《The Communication Review》2018,21(1):46-65

A number of voices have emerged in U.S. political discourse questioning the legitimacy of American exceptionalism, suggesting we are in a “post-American world.” Our research examines the effects that political messages that explicitly challenge American exceptionalism can have on U.S. public opinion. Drawing upon social identity theory, we find that explicit challenges to American exceptionalism significantly impact Americans’ views toward their own nation, their willingness to denigrate foreign publics, and their broader foreign policy preferences.  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   

“Oh,I’m Here!”: Social Media’s Impact on the Cross-cultural Adaptation of Students Studying Abroad     

Todd L. Sandel 《Journal of Intercultural Communication Research》2014,43(1):1-29

This study investigates the perceptions and interpretations of social media and online communication by students engaged in study abroad programs. In-depth interviews were conducted and analyzed with 23 American and international students who completed or were engaged in a study abroad program. Results suggest that online communication enhanced the students’ experience, providing help with sociocultural skills, informational needs, relational bonds, and psychological well-being. Different platforms were preferred when communicating with friends versus family and intimates. Online communication between co-nationals from the student’s home country buffered both the sojourning student’s acculturative stress, and the stress and concern of distant family members.  相似文献   

Negotiations of cultural identities by Indian women engineering students in US engineering programmes     

Debalina Dutta 《Journal of Intercultural Communication Research》2016,45(3):177-195

The paper analyses the identities of Indian women engineers in the gendered organizational context of US engineering programmes. Participant narratives discuss the ways in which women are subjected to identity struggles in India due to gendered patrifocal norms that impose structural, societal, and familial pressures on women. Subsequently, when these women enter US engineering programmes, they encounter a highly masculine organizational and cultural space. Participants discuss identity dislocations, transformations, and assimilation as they seek to meld into the existing structures and find a career trajectory. I draw upon liminality theory to explore the cultural transitions, identity restructuring, and negotiations of Indian women engineers, navigating the intersections of competing and intersecting cultural norms of gender and engineering in India and the US, work, and family. The findings indicate the layers of gendered ideology that constitute engineering education in India and the US, the societal pressures of marriage and family rooted in patrifocal Indian norms, the barriers to finding an engineering job, the resources within the structures that support women, and the identification of patriarchy as the enactment of agency and as a site for change.  相似文献
