Political homophily on social network sites and users' poll skepticism

Although many studies have investigated citizens' attitudes toward polls and the political consequences, there have been no studies examining the effects of social network site (SNS) users' opinion environments on their poll skepticism. Based on prior studies on poll skepticism, we examine the relationship between perceived SNS opinion environments, poll skepticism, perceived concerns over the negative influence of the polls, and voting intention in an upcoming election. Using the survey data of the 2012 South Korean General Election, this study found that if the published polls are against respondents' political position, their homophilous SNS opinion environments promote poll skepticism, and augmented poll skepticism leads to concerns over the negative influence of the polls on other voters, which in turn increases voting intention.     

News Organizations 2.0

This study aims at understanding international news differences by studying the headlines of over 360,000 news stories posted on the Twitter pages of 12 Arabic and English news organizations. The most referenced countries as well as figures and political actors are examined in these headlines, and the results show that a number of news values elements provide insight into the nature of the news selection. While Arabic channels are mostly focused on the events taking place in the Middle East (proximity), some English-language channels show clear preference for the countries from which they are located, especially CNN and Sky News, as well as Arabic and English state-owned media outlets like France 24 and RT (agenda and ideology). The findings suggest that news content largely follows a number of news values criteria that can explain the news selection process.

The power of political talk: how and when it mobilizes politically efficacious citizens’ campaign activity during elections

Political communication scholarship has investigated the mobilization effect of citizens’ political discursive behaviors during elections. With the recent advent of SNSs Social Networking Sites (SNSs) in the political communication environment, citizens’ discursive behaviors on SNSs have received increasing academic attention. This study examines (1) whether offline political talk mediates the relationship between political self-efficacy and election campaign activity (a type of political participation); (2) whether its mediation effect differs from that of SNS political talk; and (3) how those mediation effects vary according to citizens’ endorsed political ideologies. The results reveal that the effects of both offline and SNS political talk are statistically significant among conservatives, liberals, and moderates. Interestingly, the mediation effect of SNS political talk was substantially larger among liberals than among conservatives or moderates (i.e. a moderated mediation effect), while the effect of offline political talk was consistent across all three ideological groups. This study demonstrates that the electoral mobilization effect of SNSs is ideology-dependent, and is particularly based on the mismatch between SNS users’ political ideology and the current government's political orientation. Implications and limitations of the study are also discussed.
