This paper combines the persuasion knowledge model (PKM) and priming theory to investigate the effects of different appeal types in negative political ads on voters' cognitive responses and candidate responses, and explore the moderating effect of an important candidate-related variable: poll ranking. The results indicate that negative advertising based on rational appeals is more beneficial to candidates who lag in the polls. However, negative ads based on emotional appeals generate better responses from voters when used by poll leaders. These effects are observed regardless of whether the race is between an incumbent and a challenger or two challengers.  相似文献

Despite the prevalence of fact-checking, little is known about who posts fact-checks online. Based upon a content analysis of Facebook and Twitter digital trace data and a linked online survey (N?=?783), this study reveals that sharing fact-checks in political conversations on social media is linked to age, ideology, and political behaviors. Moreover, an individual’s need for orientation (NFO) is an even stronger predictor of sharing a fact-check than ideological intensity or relevance, alone, and also influences the type of fact-check format (with or without a rating scale) that is shared. Finally, participants generally shared fact-checks to reinforce their existing attitudes. Consequently, concerns over the effects of fact-checking should move beyond a limited-effects approach (e.g., changing attitudes) to also include reinforcing accurate beliefs.  相似文献

ABSTRACT

We introduce what user analytics can do in the first half of the paper and then illustrate how to do user analytics in the second half. In the current context, user analytics refers to a set of diverse communication research methods on uses and effects of social media. User analytics has evolved from TV ratings research to online user research. The history illustrates what data sources, measures, and analyses can be used for what types of research questions under user analytics. We discuss the similarities of and differences between user analytics and other methods of computational communication research (e.g. content mining and online experiments), and compare the strengths and weaknesses of user analytics with traditional quantitative methods (e.g. survey). Finally, we present an application study of Chinese bloggers to demonstrate how to employ user analytics methods to study the production, consumption, and effects of user-generated content.  相似文献

Social media is being adopted at a rapid pace by governments around world and across different levels of government. In Canada, federal, provincial and municipal governments created social media accounts in 2000s and are now using them to interact with the public. Studies to date, however, focus primarily on social media strategies and practices of government agencies while government social media users' behaviors and perspectives remain understudied. This study analyzes experiences of government social media users and how they interact on Twitter and Facebook accounts maintained by a Canadian federal government agency – Immigration, Refugees and Citizenship Canada (IRCC). It also explores why users chose to interact on social media as well as their perspectives. The findings suggest that Canadian immigration agencies are using social media as a customer services tool, and migrant social media users are turning to government social media to hear directly from the government agencies and are expecting personalized answers.  相似文献

This study extends the cognitive mediation model (CMM) by examining the role of social media in cultivating public science knowledge. A sample of 901 Singaporeans was collected through an online survey panel. The results showed that the CMM could be applied to a social media context with a focus on science literacy. Specifically, the findings indicated that people with higher levels of surveillance gratification and social utility motivations tended to pay more attention and to elaborate more about science news that they encounter on social media. Likewise, people with greater social utility motivation tended to engage in greater interpersonal discussions on social media. Notably, attention to news on social media had an indirect association with science knowledge through news elaboration and interpersonal discussion on social media. Implications for theory and practice for science communication were discussed.  相似文献

In this study, we propose a theoretical framework through which we examine the direct and the indirect effects of advertising on college students’ materialistic attitudes in China. The framework is built on the influence-of-presumed-influence model, which allows us to examine how advertising and peer influence interact with each other and exert joint effects. We conducted a survey of 210 undergraduate students aged from 17 to 24 in Beijing, China. Results of the survey suggest that, in addition to its direct effect, advertising produces an indirect effect on college students’ materialism via their presumed advertising influence on peers. The findings of this study have practical implications for both educators and marketers.  相似文献

This paper explores the dynamic between media and social-political forces through a content analysis of Chinese media coverage of intellectual property rights (IPRs) since China's accession to the World Trade Organization in 2001. We examined how media attributes, such as party affiliation and media location, have influenced the use of media frames. Three media frames were extracted from previous studies: (1) national interest; (2) cost and benefit; and (3) legal/contractual. Our results demonstrate that both media attributes exert significant influence on the use of media frames in IPRs coverage: the closer a news organization is affiliated with the Chinese Communist Party, the more likely it would adopt a national interest frame. Moreover, national press and party newspapers are more likely to adopt the national interest frame in covering IPRs-related issues; whereas, regional/popular and professional press are more likely to report the IPRs-related issues from economic and legal perspectives.  相似文献

This study sheds light on the recent use of social media for protests, with the 2016 South Korean candle light vigils as the case study. An extensive amount of literature has explored social media’s potential for informing and mobilizing the public to engage in protest activities. Previous research has mainly focused on the direct effect of social media on protest engagement. Moving beyond the direct effect, this paper sought a better understanding of social media’s role in the democratic process by examining how social media affects political knowledge and protest participation, depending on an individual’s political interest level. To test these relationships, this study used survey data collected in South Korea during the mass candlelight vigils in South Korea in 2016 (N?=?922). Findings suggest that the knowledge gap narrowed amongst those with high social media use, mainly due to a greater knowledge drop for those with high political interest. On the other hand, when it comes to participation, the participation gap widened amongst those with high social media use, largely due to a greater increase in participation for those with high political interest. Implications and directions for future research are discussed.  相似文献

The number of Web users whose first language is not English continues to grow, as does the amount of content provided in languages other than English. This poses new challenges for actors on the Web, such as in which language(s) content should be offered, how search tools should deal with mono- and multilingual content, and how users can make the best use of navigation and search options, suited to their individual linguistic skills. How should these challenges be dealt with? Technological approaches to non-English (or in general, cross-language) Web search have made large progress; however, translation remains a hard problem. This precludes a low-cost but high-quality blanket all-language coverage of the whole Web. In this paper, we propose a user-centric approach to answering questions of where to best concentrate efforts and investments. Drawing on linguistic research, we describe data on the availability of content and access to it in first and second languages across the Web. We then present three studies that investigated the impact of the availability (or not) of first-language content and access forms on user behaviour and attitudes. The results indicate that non-English languages are under-represented on the Web and that this is partly due to content-creation, link-setting and link-following behaviour. They also show that user satisfaction is influenced both by the cognitive effort of searching and the availability of alternative information in that language. These findings suggest that more cross-language tools are desirable. However, they also indicate that context (such as user groups’ domain expertise or site type) should be considered when tradeoffs between information quality and multilinguality need to be taken into account.  相似文献

This study explored the differences in young consumers' cognitive responses to visual ads across two cultures. In an experiment, 120 college students from the USA and 120 college students from China were exposed to different types of visual ads, and subsequently participants were instructed to recall objects from the ads, and to list thoughts regarding the product/brand meanings. It was found that compared with Chinese participants, participants from the USA recalled more salient objects and generated more product/brand thoughts elicited by salient objects from the ads. Moreover, Chinese participants were more likely to assign a social role to a person recalled from the ads than their American counterparts. These findings suggested that young Americans attended more to salient objects in the ads, and therefore are more analytic than their Chinese participants. Implications for international advertising were provided.  相似文献

Background

During the COVID-19 pandemic period, the level of anxiety and the duration of social media use increased in university students.

Objectives

This study aimed to examine the relationship between coronavirus anxiety and social media addiction in university students.

Methods

The sample consisted of 346 university students in Turkey. The data were collected online using the Sociodemographic Data Form, the Coronavirus Anxiety Scale Short Form and the Social Network Addiction Scale. The data were analysed using one-way analysis of variance, Mann–Whitney U test, Pearson correlation analysis, chi-square analysis and multiple linear regression analysis.

Results

The results showed that the mean coronavirus anxiety score was higher in men than in women. Social media addiction increased as the daily time spent by the students on social media increased. A positive correlation was found between the daily time spent on social media before the pandemic and social media usage during the pandemic. It was concluded that students use social media more during the pandemic than before it and that social media addiction increases as the students' coronavirus anxiety increases.

Conclusion

It is important to plan initiatives to reduce coronavirus anxiety to prevent social media addiction in young people.

Study Location and Sample

The research population consisted of 1st and 2nd year students who are studying in the Medical Services and Techniques Department of Vocational School of Health Services at a university located in the west of Turkey, during the Fall Term of academic year 2020–2021. Students in this department are studying in anaesthesia, dialysis, first and emergency aid, medical laboratory techniques, medical imaging technique, and medical documentation and secretarial programmes.  相似文献

Online public response to health emergencies is a major and complex public health issue. This study employs hierarchical linear modeling to investigate the speed of online users’ response to health emergency information on Chinese microblogging sites. The distribution of response speed for all posts is highly skewed. Only a minimal number of posts are forwarded in less than one minute. We further examine the effects of the characteristics of original messages as well as the effects of the factors of reposted messages and information transmitters, to determine the response time of messages on health emergencies. Original messages with different emotional orientations have different response times. The homophily of geographical location among dyadic information transmitters, the addressivity of reposted messages, and the degree of activity and popularity of information transmitters shorten the response time. This study expands the social amplification of risk model to an online context and contributes to the literature on information diffusion by identifying the effects of dyadic relationships among information transmitters. Practical implications are briefly discussed.  相似文献
