Political information sharing in social media offers citizens opportunities to engage with news and express their political views, but how do different patterns of online political information exposure, including both incidental and selective exposure, affect sharing? Using two-wave panel survey data collected in the United States, we examine the relationship between incidental and selective exposure and their consequent links to political information sharing, across different levels of strength

Expression has the power to shape how we see ourselves. In this paper, we argue that the dynamics of political expression on social media can influence not only political behavior, but also citizens’ more fundamental political self-concepts. Specifically, political expression on social media can entail a public commitment to a political self-presentation, which may lead individuals to perceive themselves as politically active, interested, efficacious, and knowledgeable. Analyzing panel survey da

Building on prior studies suggesting that social media can facilitate offline political participation, this study seeks to clarify the mechanism behind this link. Social media may encourage social learning of political engagement due to their unique affordances such as visibility (i.e. once-invisible political activities by others are now visible on social media feeds). By analyzing a two-wave survey conducted before the 2016 presidential election in the United States, this study tests a theoret

This study investigates factors predicting political information sharing on social media in the election context. Specifically, the current study examines how users’ six motivations for political information sharing and exposure to political disagreement on social media predict their political information sharing behaviors. Analyses of national survey data collected before the 2018 U.S. midterm election suggest that criticism, informing, and socialization motivations, but not expression, awarene

Although selective avoidance, commonly practiced as unfriending and muting on social media, has been assumed to be at odds with the democratic ideal of deliberation, academic literature says little about its antecedents and consequences. Drawing from the framework of psychological needs for information processing, we examine whether need for cognition and need to evaluate interact to predict selective avoidance, which then facilitates political expression on social media. Analyses of a two-wave

The pursuit of media diversity as a policy goal finds its foundation in First Amendment values which assume that the public welfare requires broad dissemination of information from diverse and antagonistic sources. Using 5 waves of panel data collected during the 2008 presidential campaign in the U.S., this article empirically examines the assumption that seeking diverse and antagonistic viewpoints reflects good citizenship. The results suggest that heavy consumption of liberal and conservative

Social media, as sources of political news and sites of political discussion, may be novel environments for political learning. Many early reports, however, failed to find that social media use promotes gains in political knowledge. Prior research has not yet fully explored the possibility based on the communication mediation model that exposure to political information on social media facilitates political expression, which may subsequently encourage political learning. We find support for this

Although scholars consider it important for citizens to seek diverse information to optimize citizenship, a growing body of research suggests that many people predominantly expose themselves to information that confirms their previous beliefs. Using four waves of survey data from an online panel of 2,450 Americans, this study explores a disconnect between information values and practices to identify (1) whether citizens exemplify the diversity-seeking values endorsed in communication scholarship

In the film industry, which is notoriously high risk, sequels and adaptations stand out as successful films. Conceptualizing adaptations and sequels as extended brands, this paper takes an in-depth look at brand extension strategies in the film industry by analyzing films released from 2010 to 2013 in the U.S. This paper puts forward five adaptations types by their source materials (i.e., adaptations from video games; TV series; toy lines; comic books; and books), and examines which types of ada

News organizations, faced with financial challenges in transitioning to a digital era, have embraced social media to attract an audience. Little, however, is empirically known regarding which factors generate engagement on social media to drive traffic to dedicated news websites. To answer this question, digital traffic of top 50 news organizations and 230,375 posts made by 41 accounts of these organizations on a social media platform, Tumblr, were analyzed. The results suggest that both still a

Achieving diversity has long been a goal of U.S. communications policy. However, the diversity and minority preferences governing the Federal Communications Commission’s broadcast ownership policies have been challenged on the basis of doubts concerning the assumed nexus of minority ownership, a diverse workforce, and content: the triangle. Acknowledging the lack of consensus regarding whether the triangle actually exists, this article reviews previous studies (the majority of which adopted quan

스마트 폰 보급의 확대는 이전의 휴대전화 기기와는 다르게 새로운 형태의 서비스와 산업의 발생을 촉발하고 있다. 특히 온라인 쇼핑 산업에서 스마트 폰에 설치되는 모바일 앱을 이용한 구매 규모는 빠르게 증가하고 있다. 스마트 폰의 휴대성과 이동성 뿐 만 아니라 앱의 양방향성으로 인해 장소나 시간에 구애받지 않고 온라인 쇼핑이 가능하다. 국내 모바일 쇼핑 시장의 규모는 2016년에 PC 쇼핑 시장의 규모를 넘어섰으며 그 격차는 점점 확대 될 전망이다. 따라서 본 연구에서는 첫 번째, 온라인 쇼핑의 정의와 유형에 대해 알아보고, 둘째로 대학생들을 대상으로 모바일 앱의 특성이 오픈 마켓 쇼핑 고객의 만족과 구매의도에 미치는 영향을 알아보기 위해 척도를 개발하고 이를 실증분석을 통해 분석하였다. 연구결과 앱의 속성으로 디자인, 효율성, 정보가치, 고객 서비스, A/S, 다양성, 보안성 등으로 확인되었다. 효율성과 고객만족, 구매의도 간 영향관계가 밀접하다는 것을 도출하였다. 본 연구 결과를 바

Digital media allow users the ability to engage in and be exposed to trolling. Although many people may enjoy the occasional opportunity to witness others being trolled, a relative minority directly troll others, those whom we can label overt trolls. Nevertheless, features afforded on social media and online communities (e.g., likes, upvotes) make it accessible for people to positively react to and support trolling, becoming supportive trolls, a potential steppingstone into overt trolling. In th

Although the film industry is high risk, sequels and films adapted from novels or comic books can be financially successful because they can capitalise on the established brands of their parent work. Focusing on sequels and adaptations as extended lines and brands, this paper analysed 2,490 films released between 2010 and 2013 in the U.S. to examine what types of films were successful in terms of opening weekend gross and non-opening gross. During opening weekends, while sequels generated higher
