媒体监督对公司治理中的投资者保护

转型经济中正式制度的失灵或低效使得媒体监督作为一种法律外替代机制在公司治理中发挥着重要作用,媒体监督能够降低外部投资者的信息不对称程度,提升公司治理效率。结合媒体监督与公司治理的耦合机理,分析了媒体监督在公司治理中对投资者保护的作用,指出媒体的信息制造功能有利于缓解公司治理中的信息不对称,从而迫使公司高管改变行为,并通过声誉机制对投资者的决策行为发挥引导作用。从媒体公信力、公司公共关系努力以及共同社会价值取向等方面总结了影响媒体监督发挥非正式治理作用的因素。结合我国实际情况分析了媒体监督所遇到的困境,并给出了提高我国媒体监督在公司治理和投资者保护中发挥作用的建议。     

Knowledge of Suicide Risk Factors,But Not Suicide Ideation Severity,Is Greater Among College Students Who Viewed 13 Reasons Why

Abstract

Objective: To test associations between viewing 13 Reasons Why, Season 1 and past week suicide ideation severity, behavior risk, stigma, and knowledge in college students. To explore whether personal exposure to suicide and depressive symptom severity moderated these associations. Participants: Eight-hundred and eighteen college students, 64% (n?=?522) of whom watched 13 Reasons Why. Methods: Students completed surveys online. Multivariate negative binomial regressions were used to test associations between watching 13 Reasons Why and suicide-related variables, and interaction terms. Results: Suicide ideation severity and suicide behavior risk were not significantly associated with viewing 13 Reasons Why; however, there was limited statistical power to detect associations. The association between watching 13 Reasons Why and greater suicide knowledge was stronger among those who did not have personal exposure to suicide. Conclusions: 13 Reasons Why may be a platform for psychoeducation on suicide, particularly among those who do not have personal exposure.     

The Social Media Release as a public relations tool: Intentions to use among B2B bloggers

The Social Media Release (SMR) is emerging as a potentially powerful public relations tool in a world of social network media, particularly when targeted at influential bloggers. The research described here studies the factors that influence bloggers to use SMRs, using the Technology Acceptance Model as a theoretical framework, concentrating specifically on their perceptions of usefulness and ease of use.     

以色列在非对称战争中的媒体策略调整

战争与媒体有着密切的联系。尤其是在实力悬殊的非对称战争中,媒体策略的运用在造成以弱胜强或者强者不能赢局面的过程中发挥了重要作用。以色列是地处中东危机频发的国家,拥有比较完善的危机管理机制,并通过战争总结经验教训,不断完善。本文以2006年黎以战争和2008年至2009年之交的加沙战争为例,考察了以色列在两次非对称战争中的媒体政策的调整,政府新闻部门、国防军和媒体的组合拳是当今以色列在非对称战争中媒体策略运用的主要特点,并取得了比较明显的效果。因此,媒体战、信息战在今后的非对称战争中也将占据更为重要的位置。     

Media exposure and the engaged citizen: How the media shape political participation

Media exposure is widely known to increase institutional forms of political participation such as voting. Less well understood is whether media exposure also affects protest, a less institutional form of engagement. This paper examines the mechanics through which this relationship operates by considering the media's direct and indirect effect on voting and protesting, via political trust, efficacy, and knowledge. We make these comparisons by analyzing the unique Jennings panel dataset that collects information on respondents at three separate points. The results show that media exposure affects voting more than protesting and that these relationships operate through different mechanisms. While media exposure leads to voting because it increases political knowledge, it is associated with protest via external political efficacy. Furthermore, while this relationship is causal for voting it is only correlational for protest. The results illustrate the importance of disentangling forms of political engagement when considering media effects.     

Media,fear, and nuclear energy: A case study

Although electricity generation technologies and safety have improved gradually over time, nuclear power, including generation facilities and waste repositories, are seemingly stigmatized in American culture. Contemporary literature has considered the impact of widely broadcasting nuclear accidents and how media coverage might alter public risk perceptions and in turn, U.S. nuclear policy. This paper discusses the vacillation of public support in recent decades and its ties to both media and scientific reporting. The analysis identifies how media coverage of accidents at Chernobyl, Three-Mile Island, and Fukushima overwhelmed scientific claims of safety and security in nuclear energy production. Additionally, the discussion considers how to bridge the information gap between scientists, citizens, and policymakers through increased knowledge dissemination. Finally, the implications of improved scientific communication in democratic policymaking processes are discussed.     

What kind of country we want for our children: an analysis of media coverage of the 2017 New Zealand General Election

ABSTRACT

This article is the third in a series investigating media reporting of New Zealand elections. Based on content analysis of 510 articles published in the New Zealand Herald, and thematic analysis of a subset of news stories related to young people, the study examines media coverage of the 2017 elections by looking at the topics of news stories, presence of party policies, diversity of sources and references to social groups. Comparing the 2017 results with the results of the Herald’s coverage of 2014 elections, we register a shift towards a stronger presence of policy issues, more female voices in the reports and significantly higher reference to young people. We further investigated the high number of references to young people by conducting qualitative analysis on the subset of articles mentioning young people.     

Media Production as Therapy: A Systematic Review

Abstract

The rapidly changing communication environment of the digital age has generated needed discussion regarding implications of media technologies for social work practice. Yet scarce research has considered the therapeutic value of media technologies for social work practice. This systematic review explores how media production is used as a therapeutic intervention in human services to identify the therapeutic value and potential challenges of its application in the field. Media Production as Therapy (MPT) affords a range of therapeutic outcomes, including self- and community-awareness, self-reflection and self-correction practices, self-expression and story-sharing, and processing trauma. Challenges confronted through MPT include time and resource constraints, logistical difficulties, issues of authenticity, and dissemination concerns. Despite limited research, this review provides needed guidance for social workers to harness technology for social good, operating in the digital space to implement MPT interventions that afford a range of therapeutic benefits to clients in an increasingly mediated world.     

Role of Gambling Media Exposure in Influencing Trajectories Among College Students

In the study, a model of the relationship between mass media depictions of gambling and subsequent gambling attitudes and behavioral intentions of college students was developed. A survey was conducted with 229 undergraduate students (79.5% female, mean age = 20.5, SD = 2.04) enrolled in three different communication courses at a large southeastern university. Through structural equation analysis, the six hypotheses of this study were analyzed using the method of maximum likelihood with AMOS 6. The model was consistent with the hypotheses that media exposure impacts gambling attitudes and behavioral intentions both positively and negatively, depending on the valence of the gambling depiction. Theoretical and practical implications of mass media exposure and gambling behaviors are discussed, and future research directions are outlined.     

关于传播学交叉研究的路径思考——兼评邵培仁教授《媒介地理学》

学科发展的科层制困境长期困扰着传播学科的建设,学科交叉研究作为解决这一困境的手段之一,在促进学科创新的同时,也给学科的独立定位带来了消极影响。如何既建立起传播学自己的核心框架,又在更广阔的社会背景下进行分析,成为新时期传播学者们的主要探索方向。邵培仁的《媒介地理学》一书在问题意识、概念体系、范式革命、研究方法、人文关怀等五个方面做出了自己独特的贡献,在对传播学科危机深入反思的基础上投身实践,努力建构起了一个"既有中国学术主体性又有世界元素和全球视野"的知识体系。理论创新的贡献不仅在于分析当下问题的应用,更在于将来的学科发展,该书最大的意义正在于此。
