移动社交网络用户对产品推荐信息反应意愿研究

[目的/意义]研究移动社交网络情境中用户与联系人关系、用户感知联系人行为如何影响用户对产品推荐信息反应意愿,并就研究结果提出管理对策。[方法/过程]通过手机微信平台收集的316份有效问卷,运用偏最小二乘回归法对数据进行分析。[结果/结论]结果表明：对联系人推荐的认知信任和情感信任正向影响用户对产品推荐信息反应意愿;亲密度和过去经历正向影响联系人推荐的认知信任和情感信任;过度发布行为负向影响联系人推荐的认知信任和情感信任。但是,相似性与对联系人推荐的认知信任和情感信任之间关系未获得支持。     

Value of User-generated Content: Perceptions and Practices Regarding Social and Mobile Media in Two Italian Radio Stations

Despite continuous attempts in the mass media landscape to integrate new forms of two-way interaction, limits of interactive media have become a focal theme of criticism since two-way interaction has been introduced. Interviews with national and regional radio stations’ professionals have revealed divergent perceptions not only based on the various actors, but also based on national and regional practices.

This study outlines lingering limitations of user-generated content implementation, based on conceptualizations of affordances of interactivity and organizational practices associated with it. I argue that the new platforms don’t necessarily eliminate the biases that have been addressed by the previous two-way communication.     

Identity on Social Networks as a Cue: Identity,Retweets, and Credibility

The current study investigates how social media affordances influence individuals’ source credibility perceptions in the presence of risk information, specifically examining how bandwagon heuristics interact with different identity heuristics at the individual level. The MAIN model and warranting theory serve as the theoretical framework to examine the effects of bandwagon cues and identity cues embedded in retweets and users’ profile pages for health and risk online information processing. A posttest-only experiment with a self-report questionnaire was administered to participants. Results indicate that different online heuristic cues impact the judgments of competence, goodwill, and trustworthiness. Authority cues strongly influenced source credibility perceptions. A reverse-bandwagon effect was observed in influencing source credibility judgments.

基于社会资本的异构社会网络构建研究

在图书情报领域,不同的知识单元(如文献、作者、机构、期刊、学科、主题词和关键词等因各式各样的关联而形成了复杂的知识网络.传统的知识网络构建过程中往往仅依赖知识单元之间的单一关系,因而形成了多个独立的单关系网络,然而真实的知识单元之间往往是多种关系复杂地交织在一起.为解决复杂的知识网络构建这一问题,本文以科研人员这一知识单元为例,提出基于多关系融合的异构社会网络构建方法.将社会网络的构建与社会网络三大核心理论之一的社会资本理论相结合,依据社会资本的三个维度来进行关联测度和融合,生成异构社会网络.针对科研组织的实证研究揭示出异构社会网络能够更好地融合研究人员之间与科研兴趣有关的多种关联,为更精确的社区划分提供帮助.     

Best Practices of Library Mobile Website Design: A Literature Review

This article is intended to serve as a guide for librarians developing mobile Websites to be linked to their current library Website. Kroski (2008a) defines the mobile Web as “the World Wide Web accessed through a mobile device, ranging from a cellular phone to an iPod Touch. It includes the entirety of the Web and is not limited to Websites that are specifically designed for mobile viewing” (5). This literature review focuses on the mobile Web, mobile device usage, and best practices for designing mobile Websites for libraries.     

Social Media and Speed-Driven Journalism: Expectations and Practices

To examine how journalists use, and are affected by, social media in their pursuit for speed, this study conducted in-depth interviews with 11 journalists from various U.S. national, metropolitan, and local newspapers. Findings revealed an industry-wide expectation that journalists engage with audiences on social media. But in terms of practice, most interviewees reported that they mainly use Twitter to facilitate news work (i.e., contact hard-to-reach sources) and communicate with other journalists; audiences are rarely their focus on social media. The interviewees were also asked about their perception of how Twitter affects audiences. Most interviewees were unsure of its impact on credibility, but believed that it may promote news use, although not contribute to news organizations’ bottom line. This study offers five reasons why social media are not saving the newspaper industry, and discusses managerial implications regarding the gap between social media expectations and practices.     

哈贝马斯的交往行动理论与博物馆社会影响力研究

本文中的“影响力”是指在社会中,一个个体人或机构,在交往行动中通过信息（information）的告知（message）和理解（understanding）,对他人行为和观念造成改观的能力。根据行为双方的身份和角色限定,这种能力可以被划分为权力影响力（influence of power）和非权力影响力（influence of non—power）。权力影响力的发生,必须以交互行为的双方之间存在着某种契约强制性的关系,如科层中的上下级、传统家族中的父子等为前提,     

Mobile Phone Use in AA Networks: An Exploratory Study

The purpose of this study was to explore the role of mobile phone use for mutual support within social networks of Alcoholic Anonymous (AA). A sample of mobile phone owners and non-owners in AA was surveyed to assess their perceptions and uses of this technology. Mobile phone owners reported very positive perceptions of the technology as a resource for recovery and heavy use of the mobile phone for this purpose. Non-owners also reported positive perceptions of the mobile phone as a resource for recovery and that expense was the primary reason for not using a mobile phone in their recovery efforts. Heuristic, theoretical, and practical implications of the study are included in the discussion.

Participation and Pedagogy: Connecting the Social Web to ACRL Learning Outcomes

This article examines the connection between ACRL information literacy standards and constructivist pedagogy. This connection is used to support use of Web 2.0 tools for information literacy instruction. Sample exercises using these tools are provided for each ACRL learning outcome, and the tools' suitability for the constructivist approach is reasserted.     

Computer-Mediated False Consensus: Radical Online Groups,Social Networks and News Media

This study draws on survey data obtained from members in neo-Nazi discussion forums and builds on evidence that participation in these forums exacerbates false consensus, that is, overestimating public support for own views. This study goes further to test whether contacts with dissimilar offline social networks as well as exposure to ideologically dissimilar news media attenuate false consensus and its association with online participation. Contrary to predictions, politically dissimilar networks do not reduce false consensus among the analyzed sample. Exposure to ideologically dissimilar news media, on the other hand, results in more accurate estimates (main effect), but it exacerbates false consensus as resulting from participation in neo-Nazi online groups (interactive effect). Theoretical and practical implications are discussed.     

圈层分化:移动社交下的过度媒介化

从传播学的角度看,圈层分化是人际传播所建构的群体认同下的强链接作用,其既利于维系人际交往圈,也是过度媒介化的结果,是移动社交下所衍生出的显著产物。在移动社交时代,人际交往主体对固化的人际交往圈所具有的双重性具有明晰的认知,才可能由内而外地建构自我,了解"主我"和"客我",提高自身媒介素养,更好地适应现代化的人际交往。     

基于社交网络的社交关系强度分类研究1）

本文利用监督学习的方法从社交网络的用户数据中分两个阶段挖掘最佳的社交关系强度分类模型,并进一步探讨不同用户数据对于社交关系强度的区分能力。研究发现,基于贝叶斯网络算法的分类模型在区分强社交关系的过程中被证明最有效,而基于 Logistic 回归算法的分类模型则在区分出临时社交关系的过程中表现最佳。研究还通过属性分析发现互动性因素总体上对社交关系强度的区分能力最为突出,相似性因素中的共同好友数也有很好的区分能力,但时间性因素对于社交关系强度的区分能力没有被发掘出来。

社会网络在开放式知识创新中的应用价值研究

通过对关于社会网络、知识创新和开放式创新相关文献进行回顾,试图探索社会网络的不同类型、社会资本的不同维度如何影响知识创新。分析结果显示出社会网络不同因素与其成员创造知识的能力之间存在复杂关系。研究结果表明密集型网络中的知识类型趋向于同质性,而松散型网络中的知识类型趋向于异质性。针对不同类型的网络结构提出开放式知识创新策略。最后,设计社会网络中开放式知识创新的模型。
