Contagious Media Effects: How Media Use and Exposure to Game-Framed News Influence Media Trust

The purpose of this study is to investigate the extent to which trust in media is affected by personal media use and the framing of politics as a strategic game. The study is based on a four-wave panel survey matched with media content data, which allows us to investigate not only correlations but also individual-level effects on media trust. In accordance with previous research, our analyses show that the use of specific media types leads to more trust in those specific media. The results also show that media framing of politics as a strategic game has a negative effect on trust in the media. The more citizens are exposed to game-framed news, the less they tend to trust the media, with the exception of tabloid newspapers. Overall, these results lend support to the assumption of contagious effects of game-framed news. In a concluding section, we sum up our results and discuss the implications of our findings.     

Media Coverage of Adolescent and Celebrity Suicides and Imitation Suicides among Adolescents

Suicide is the second leading cause of death among adolescents in the United States. Imitation plays an important role in adolescent suicides. Identification theory suggests that media coverage of adolescent suicides can increase imitation suicides among adolescents. The present study examines this possibility using data collected from South Korea. It also explores the relationship between media coverage of celebrity suicides and suicide rates among adolescents. We found that adolescent suicides increase after media coverage of either an adolescent’s suicide or a domestic celebrity’s suicide.     

The Media,the Medium,and Malaise: Assessing the Effects of Campaign Media Exposure with Panel Data

In this article we extend recent work on exposure to campaign advertisements, comparing the effects of television ads, radio ads, and campaign-related e-mails using an unusual panel data set that provides information on multiple media sources. Our findings, which control for the endogeneity problem that has plagued much work in political communications, confirm that media exposure does affect citizen attitudes. We also find additional evidence that the medium matters, with exposure to television ads tending to undermine system-supporting attitudes, whereas exposure to radio ads has an overall positive effect; contrary to expectations, the “new medium” of campaign e-mails had no discernible effect.     

新媒体语境下明星形象的“自塑”与“他塑”

技术理性日益改变人们的生活方式,新媒介的出现也给话语的生成带来颠覆性变化。明星作为公众人物本身就具有强大的社会属性,他们集聚了多重的目光,网络社会给明星带去更为复杂的表演"舞台"。近年来,明星人设崩塌的现象比比皆是,并且通过网络传播形成了恶劣社会影响,这进一步让我们思考明星形象在构建时面临的困境。文章通过探讨明星主体自我塑造的方式来证明其商品化的本质,指出网络环境已然对其形成了"全景监狱"式的监控;明星游荡在"自我"和"他者"间的焦虑引发了畸形的社会认知模式,文章由此强调了当下明星承担社会责任的必要性。     

The Effects of Sports Media Exposure on College Students' Rape Myth Beliefs and Intentions to Intervene in a Sexual Assault

An online survey was fielded to freshmen living in residence halls at a northwestern university in the United States. Structural equation modeling was used to investigate the structure of relationships among exposure to mainstream sports media, rape myth acceptance, and intentions to intervene in sexual assault situations while controlling for gender traits. Given that prior research suggests men and women differ in their beliefs about sexual assault, analyses were performed on male (n = 111) and female (n = 241) respondents separately. Among women, exposure to sports media was positively associated with rape myth acceptance, which in turn was negatively associated with intentions to intervene in sexual assault situations. Among men, consuming sports media was negatively associated with intentions to intervene in a sexual assault. The findings suggest that exposure to some sports media may be negatively associated to individuals' intentions to intervene in a sexual assault.     

Measuring Exposure to Media with Antisocial and Prosocial Content: An Extended Version of the Content-based Media Exposure Scale (C-ME2)

The present research developed a measure for exposure to both antisocial and prosocial media content by revising and extending a previous Content-based Media Exposure Scale (C-ME). The validity and reliability of the C-ME2 was tested in two independent samples (N = 678), among young adults (Study 1) and adolescents (Study 2). Results of Confirmatory Factor Analyses showed good fit, in both studies, for both antisocial and prosocial dimensions of media content, and for both males and females. Furthermore, the C-ME2 explains unique variance beyond previous measures of violent and general media exposure. Evidence is presented of reliability, discriminant and predictive validity of the C-ME2, measuring both frequency and exposure to specific content of media. The C-ME2 covers all media platforms, is easy to use in all research designs, and allows for standardization and systematic comparisons across studies.     

Media Exposure or Media Hype: Evidence from Initial Public Offering Stocks in Taiwan

It is frequently observed that the price at which a firm's stock is listed for its initial public offering (IPO) is considerably less than the price at which it trades at the end of its first day of trading, a phenomenon known as underpricing. This article examines how media-provided information affects IPO underpricing and trading turnover. The empirical findings show that the more media coverage a firm receives over a substantial period of time prior to its IPO, the smaller the degree to which its stock is underpriced. However, more media coverage immediately prior to the IPO date increases the degree of underpricing. It is also shown that the tenor of media coverage affects the relations between the volume of near-term, pre-IPO information provided by media and both underpricing and trading turnover.     

Impacts of Media Conglomerates' Dual Diversification on Financial Performance

This study examines the impact of media firms' diversification on their financial performance based on the product and geographical diversification activities and performance of the top 26 media firms from 1991 to 2002. The empirical results generally indicate that related product and international diversification contributes to better financial performance. However, excessive diversification, which leads to a high degree of unrelated diversification, might decrease performance. There also appears to be a hurdle level for diversification, prior to which expanding businesses in product and international markets may need considerable investment and produce negative cash flow. Beyond that threshold, dual diversification significantly contributes to increases in cash flow.

The Role of Engagement in Learning From Active and Incidental News Exposure on Social Media

The growing reliance on social media as news platforms may lead to more passive news consumption but also offers greater potential for engaging in news. This study investigates the role of engagement with news content on Facebook and Twitter between news exposure and current events knowledge. An online survey (N = 400) tests the relationships between social media news seeking, incidental exposure to news on social media, engagement in shared news content, cognitive elaboration, and current events knowledge. The results show that both active seeking of and incidental exposure to news on both sites are linked to engagement, which is linked to greater cognitive elaboration about the content. Furthermore, engagement mediates the relationship between both types of news exposure and cognitive elaboration. However, engagement and elaboration are not related to knowledge. These results indicate that the key role of social media in news content is not knowledge gain but the ability to engage users who may be passively receiving news on these sites. This study extends the cognitive mediation model of learning from the news in the context of current social media, with updated news consumption norms such as engagement with news on these sites, and incidental news exposure.     

The Reliability and Temporal Stability of Self-reported Media Exposure: A Meta-analysis

ABSTRACT

The measurement of media exposure is essential to not only traditional audience research, but also media effects research which relies on accurate estimates of media exposure. Even in the age of digital trace data and passive audience measurement, the workhorse of basically all communication research is self-report data. This article presents a meta-analysis of the reliability and temporal stability of media exposure self-reports in 33 panel studies. Results from a Bayesian multilevel analysis show that self-reported media exposure was moderately reliable (0.69, 90% HDI: 0.65, 0.72) and highly stable (0.90, 90% HDI: 0.88, 0.92). In line with previous studies, the reliability of media exposure measures was higher in adult samples (0.72, 90% HDI: 0.69, 0.76) compared to adolescents (0.60, 90% HDI: 0.53, 0.66). Rank-order stability of media exposure was comparable in adult (0.91, 90% HDI: 0.89, 0.93) and adolescent samples (0.85, 90% HDI: 0.81, 0.90). Moderation analyses showed that self-reported exposure to specific outlets was more reliable than general media use in adult samples. Media-specific differences in reliability were only found in adolescent samples. Overall, moderate reliability in combination with high temporal stability poses important challenges for scholars investigating causes and consequences of media exposure.     

不同媒介阅读效果差异的作用机制探究

[目的/意义]为更好地传播知识,提升阅读效果,研究针对电子阅读与纸质阅读的效果差异,以实验的形式探究影响媒介阅读效果的作用机制。[方法/过程]通过实验,比较学习者在高背景信息水平的纸质阅读（P-book）条件、中等背景信息水平的iReader电子阅读条件和低背景信息水平的Word电子阅读条件下的不同阅读效果。[结果/结论]结果发现：P-book条件下,学习者在迁移测验、认知负荷、阅读速度、视角疲劳程度上的表现都要显著好于Word条件,在迁移测验上也显著好于iReader组。iReader组在阅读速度和认知负荷上显著好于Word组。得出结论：阅读效果同时受阅读媒介和阅读环境中的背景信息标记的影响。纸质阅读环境中的背景信息标记,能够缓解视觉疲劳,降低认知负荷,提高阅读阅读速度;但是阅读效果中的知识理解却更容易受阅读媒介的影响,纸质媒体更利用于知识的理解。     

新闻媒体绩效考评的悖论

媒介融合直接导致了新闻出版组织结构和生产方式的急剧变化.这种变化使得新闻媒体绩效考评中隐藏的悖论被放大,其中,考评主体、考评方式和考评结果应用的悖论显得尤为突出.文章认为,我国新闻媒体绩效考评主体方面存在着多头考评与媒体法人自主权的悖论,数据考评方式本身存在着公平悖论,考评结果应用方面的片面性和考评信息的多元性形成悖论.     

A Meta-Analytical Review of Selective Exposure to and the Enjoyment of Media Violence

A primary argument for the widespread production of media violence is that audiences want to watch violent content. This assumption is examined in this meta-analytic review of existing research on both selective exposure to and enjoyment of violence. The results show that violence has a significant effect on both selective exposure and enjoyment, but in different directions. Specifically, violence increases selective exposure but decreases enjoyment of content. Potential explanations for these effects and moderators that could influence the results (e.g., sex, aggressive personality traits, type of content) are considered, and the practical implications of these findings are discussed.
