Using the structural equation modeling method (N = 811), this study explores the structural relationships among online news consumption, political participation and social trust, with a focus on the mediating effects of online users’ deliberative perceptions and news-related online interactive activities. The analysis confirms that users’ perceptions of online deliberation exert a significant mediating effect on users’ levels of news consumption, political participation, and social trust. Users’ interactive civic messaging behaviors, on the other hand, solely enhance participatory intentions. The findings also show that the consumption of political news and the consumption of entertainment news have different effects on users’ perceptions of online deliberation, social trust, and political participation. Specifically, while political news has a direct and relatively strong influence on participation, entertainment news has a limited and indirect effect on participation. Online interactive activities are negatively associated with users’ perceived competency for online deliberation. Further implications of the study are also discussed.  相似文献

The shift to online news consumption has weakened the direct relationship between readers and news publishers. News publishers now depend on the number of clicks and comments on their news to increase their revenues. Repetitive news display or news abusing is used extensively by Korean news publishers to draw consumers’ attention to their content. This study examines the factors causing news abusing in Korea. We analyze the factors that affect both news abusing frequency and intensity, and examine how they vary in both intra-media and inter-media contexts. We empirically test the relationship between the number of clicks (comments on the news posted) and the abusing frequency of the news article (abusing intensity of the news article). Finally, we try to identify the differences in the relationships between the effects of news abusing and the number of clicks and comments based on news abusing patterns and news article types.  相似文献

Because online news is pervasive and online comments provide space for people to express their opinions and participate in open discussions, they affect public opinion. However, at least in Korea, male users seem not only to be more active in consuming online news but also in commenting online. Many previous studies have investigated the gender imbalance in news consumption of not only traditional media but also online media. Although a few studies explored gender differences in online comments on news, no study has investigated such gender differences using actual data on the basic profiles of commenters. To fill the gap between previous studies and reality and address the gender imbalance in online news comments and public opinion, this study examined the differences between male and female online news commenters. Furthermore, using actual data provided by Naver, the dominant Internet portal in Korea, this study analyzed the characteristics of female news commenters and those of news content where female users most actively commented. This study found that—at least in Korea—fewer women comment on news, they are less active than men, and that there is a difference between younger and older women. This study also found that people write more comments in a day as their age increases and the gender differences decrease with age.  相似文献

This study investigates the (de)mobilizing influences of political (dis)agreement in the news and in political discussion on political attitudes and participation in new information environments. Results demonstrate the mediating functions of political ambivalence in that exposure to proattitudinal news reduces ambivalence and thereby promotes political participation, whereas exposure to counter-attitudinal news increases ambivalence and thereby discourages participation. Importantly, the effect of exposure to counter-attitudinal news on ambivalence was moderated by heterogeneous discussion networks on social network sites, such that the combination of exposure to counter-attitudinal news and to heterogeneous discussion networks amplifies ambivalence additively, and thereby augments the tendency toward demobilization. These results are interpreted as suggesting that changing media contexts may lead to complex roles of news and political discussion.  相似文献
