社交媒体信任对隐私风险感知和自我表露的影响:网络人际信任的中介效应北大核心CSSCI

社交媒体信任是影响用户隐私风险感知和自我表露的重要因素之一,本文通过网络人际信任,构建了社交媒体信任影响用户在社交媒体上的隐私风险感知与自我表露的中介效应模型。本文运用问卷调查法,使用结构方程模型对501位社交媒体用户的媒体使用数据进行了分析。实证结果显示:1.隐私风险感知与自我表露并无显著相关性;2.社交媒体信任负向影响用户的隐私风险感知,网络人际信任在其中发挥中介作用;3.社交媒体信任正向影响用户的自我表露,网络人际信任在其中发挥中介作用。因此,对于理解社交媒体信任影响隐私风险感知和自我表露的解释机制,本研究具有一定的理论贡献。

基于风险社会放大框架下的社交媒体使用对公众风险感知的影响研究

在社交媒体时代,风险信息传播的传播过程发生了极大改变,社交媒体的使用对公众风险感知的影响愈发强烈。本研究以2015年11月震惊全球的巴黎恐怖袭击事件为例,运用社会网络分析法,结合风险的社会放大框架对该社会网络中各种关系进行全面、精确的量化分析,研究事件发生后信息传播的动态网络结构。最终结果表明,事件中的风险感知网络是基于关键行动者的动态网络结构,关键行动者掌握重要信息源,中介行动者在风险信息扩散过程中充当意见领袖,使得风险信息在传播中被放大,能更快的传播至普通行动者。     

技术导向与价值导向 ——基于"地下水八成不能饮用"舆情事件框架分析的环境风险传播策略研究

网络舆论常常采用价值导向的相关框架来理解环境风险,而政府管理者却多使用技术导向的相关框架对公众实施风险传播,由此导致传播效果的受限.本研究利用舆情分析工具,对2016年4月间发生的"地下水八成不能饮用"网络舆情事件进行信息数据采集,并通过对信息文本进行框架分析,描述社会公众和政府管理者在舆情风险信息传播中所使用框架的差异,并在此基础上提出包括传播目标设定、传播方法优化和传播效果拓展等在内的相应的环境风险传播策略.     

高校科学研究情境下人格特质对知识共享的影响——以目标导向为中介变量

[目的/意义] 基于大五人格特质理论和目标导向理论,以学习导向和绩效导向为中介,构建高校教师人格特质差异对知识共享行为影响的模型。从人格特质和目标导向视角解释个体人格差异对知识共享行为的影响,有助于高校更好地激发高校教师在科学研究中的知识共享行为。[方法/过程] 通过对202名高校教师进行问卷调查,构建影响高校教师知识共享行为的概念模型,采用层次回归分析和Bootstrap方法进行检验。[结果/结论] 实证结果显示：①尽责性人格和亲和性人格对教师知识共享行为均有显著的积极影响,而开放性人格的影响不显著,其中尽责性人格的影响度最高;②学习导向和绩效导向在人格特质对知识共享行为的影响中起到部分中介作用;③相较于绩效导向,学习导向的中介效应更强,说明教师进行知识共享的学习动机更为强烈。     

风险网络：作为非人行动者的媒介与社会风险的生成

身处贝克所言的风险社会，个体对风险的感知除了亲身经历外，更多地是源于媒介提示的风险图景。大众传播时代，媒介是风险的中介化，是风险的社会放大站。但伴随着深度媒介化，风险的社会放大这种线性传递观具有明显的解释局限性。随着行动者主体的增多以及行动者网络异质性的提高，媒介在呈现风险的同时，自身也在生成风险。基于行动者网络理论视角，新媒体时代媒介化治理的关键不在于技术层面如何传递风险信息，而在于如何减少因为媒介化传播产生的“次生风险”。行动者网络视角进一步明确了当下社会风险的本质，即作为网络的风险是多元行动者共同作用的结果，是兼具不确定性和动态生成性的非线性存在。     

互联网使用对在校大学生麻醉功能的影响研究——基于对上海4所高校学生的调查分析

以网络依赖为中介变量,研究网络使用时长、频率和内容对在校大学生麻醉功能的影响。通过对上海4所高校学生的抽样调查和实证分析,研究发现在校大学生每日使用时长、使用内容中的网络娱乐、信息工具与麻醉功能显著正相关,而每周使用频率、网络消费对麻醉功能的影响不显著。此外对中介效应检验发现,网络依赖对网络娱乐、网络消费与麻醉功能的影响方面发挥重要的中介作用,而网络依赖对信息工具与麻醉功能没有中介作用。研究结果显示互联网的使用行为会对在校大学生产生麻醉功能,这些发现可以为未来的大学生教育和引导大学生合理利用互联网提供参考。

Effects of Mergers and Competition on Consumer Benefits in the Multi-Channel Video Programming Industry in Korea

This article examines the welfare benefits of cable television (CATV) merger and acquisitions in the multi-channel video programming distribution (MVPD) market. In particular, it seeks to answer whether cable subscribers are better off in competitive markets than in concentrated markets. This article estimates the impact of mergers by examining Korea's regional market-share data for MVPD operators with a hierarchical-choice model. First, the estimation results show that the consumer value of the CATV platform, in terms of the category values in a nested logit model, was significantly lower in the concentrated markets than in the more competitive markets. Second, the study compares these findings with those in the literature about the U.S. market. The following question is prompted: Why is direct broadcast satellite competitive with CATV in the United States but not in Korea? This article points out that differences in regulatory policies, particularly as they relate to the treatment of vertically integrated networks, do have significant effects on the effective boundary of MVPD competition across platforms. To support this argument, this article provides details on the policies and market characteristics of the Korean MVPD industry.     

The Value of Scholarly Journals in a Two-Sided Market

Two-sided markets are a relatively new economic concept that has relevance for scholarly communications. Scholarly journals, as well as bundles of scholarly journals, can best be understood as examples of two-sided markets, and journal-pricing issues can best be examined using this concept. Serials librarians, electronic resources librarians, and scholarly communications specialists should incorporate two-sided markets into their understanding of the shifting journals environment.     

Demographics and destiny

Although publishers are accustomed to defining audiences and markets, they rarely take into account demographic data. Knowing the size of various age groups can help publishers to distinguish between subject areas whose markets are likely to grow and those whose markets are likely to shrink or level off Kendrick Noble offers demographic profiles of the U.S. population in 1988 and 1995 and predicts some likely effects of demographic change on the markets for pubishers’ products. J. Kendrick Noble, Jr., is first vice president of Paine Webber, Inc. and a leading analyst of the publishing industry.     

The Internet as a Small-Market Radio Station Promotional Tool

The combination of radio and the Internet has been solidly documented as a cross-media success for many advertisers. However, to what extent does the medium itself share in this success as it utilizes the Internet as a promotional tool? Even less is known about radio and the Internet in small markets. Based on a survey of industry experts located at radio stations in markets ranked loo+, this paper examines current promotional executions as well as explores possible future opportunities that small-market radio stations are considering as the Internet continues to grow and change.

International Intelligence in Spain: An Approach to Information Resources for Business

The concept of international intelligence has taken on a greater importance for companies seeking to internationalize and access foreign markets. An exhaustive environmental scan—including international competitors, suppliers, clients in target countries, legislation and the political situation in other territories, and others—involves gathering the necessary information, its analysis and subsequent dissemination, and decision making. Within the context of the important role to be played by information management professionals who are specialized in foreign information, this article describes the information resources that Spanish companies have available to them that can assist them as they enter foreign markets.     

Managing Competition Through Barriers to Entry and Channel Availability in the Changing Regulatory Environment

In this article, we explore factors that influence the number of broadcasters in a market and the achievement of optimal outcomes in broadcast markets.We explore a range of barriers to entry and means of overcoming those barriers in broadcast markets.We argue that choices regarding and influences on barriers to entry and channel availability act as forms of competition management in broadcast markets. Policymakers and regulators indirectly influence markets by altering the effects of those barriers and directly influence market activities by making decisions regarding the number of competitors, market structures,and-indirectly-the financial performance of broadcasters. We argue that barriers to entry can be controlled to produce competition levels and market outcomes that promote optimal social and economic outcomes.     

Triple-Play Competition in the U.S. Telecommunications Industry: Exploring Cable Operators' Adoption Pattern of Triple-Bundled Services

The innovations of new digital technology as well as the changes in communications policies have made cable operators' triple-play services for consumers possible. In the face of the new type of competition, this study estimates the adoption pattern of triple-play services by cable operators in U.S. local telecommunications markets and discovers factors associated with cable operators' adoptions of triple-play strategies in markets. Probit regression analyses reveal that cable operators having a large video subscriber base are more likely to adopt triple-play strategies in local markets. Apparently, a large video subscriber base provides cable operators with motivation for the adoption of a triple-play strategy in order to hinder video customers' churn to other competitors and to generate additional revenue per customer.
