Experts claim that the world is increasingly polarized by emerging social media platforms. The political actors amplify the polarization through their agents' user-generated content. The extreme political ideologies sway the people sitting on the fence on these social media platforms. Using tweets on a recent policy change on identity in India, the present study seeks to perform a scientific analysis of the polarization of the debates within ordinary citizens' groups from a theoretical lens. We further highlight some of the crucial trends that triggered these polarized discussions in general. Through the lens of Echo chambers and Herd behavior, this study provides valuable insights surrounding the influencers and individuals involved in this discussion where the polarization of preferences is witnessed. Proposing a novel design of a root-level influencer, this study establishes them as polarization actors on a social media platform (Twitter). Through various engagement metrics, we also identify the role of targeted communication (hashtags) and similarity in the users' discussion across the political domain as potential behavioral explanations for opinion polarization on Twitter. 相似文献

After Officer Darren Wilson fatally shot African American teen Michael Brown in August 2014, rioters unleashed their anger on the streets of Ferguson, Missouri. Using content analysis and framing theory, this study analyzed how news organizations covered events in Ferguson on Twitter over the course of a month immediately following the shooting. Protesters were framed as troublemakers; but community leaders were not framed as “rabble-rousers.” Journalists continued to rely on official sources more than alternate sources in spite of criticism of law enforcement and other political elites, but nearly 10% of the coded tweets that relied on official sources included some element of skepticism. Tweets from cable news outlets did not show partisan bias in any significant amount; and traditional legacy news media sources utilized the Twitter platform enhancements—such as article links, photos, links to other content, or hashtags—more than their new digital media counterparts. As Twitter launched #ferguson into the national consciousness, it is quite plausible that the framing of the tweets by news agencies may have molded perceptions of larger issues about the racial health of the nation, established policies of law enforcement, and the challenge of elected leaders to resolve explosive domestic problems. 相似文献

Over the past 65 years, scholars have reframed the original model of gatekeeping to reflect the changing dynamics of news creation, distribution, and curation. In recent years, communication technologies have opened digital news gates to a proliferation of images captured by professionals and amateurs alike. Anyone with a camera or cell phone can shoot and distribute photographs and videos on the internet. Social media facilitates audience-to-audience sharing through tools such as Twitter, Facebook, Instagram, Vine, and Snapchat. This stream of visuals, along with the ease with which citizen journalists, bloggers, and tweeters can create and publish content, has changed the gatekeeping process. Few scholars, however, have addressed the impact that visuals have on the gatekeeping model, which was developed using text and broadcast stories. To address the changing role of the visual journalist and the audience, the authors conducted two studies. First, qualitative elite interviews with key visual decision-makers in Europe and the US provided questions for further exploration in the second study—an online cross-sectional survey of visual journalists who belong to three leading US organizations. The questions in this quantitative survey were also influenced by Shoemaker and Reese's hierarchy of influences and Bennett's multigated model. Findings indicate changes in the way visual journalists conceptualize their role and that of the audience. Based on these changes, this article proposes a new model of visual gatekeeping—the twenty-first-century visual news stream where “gatecheckers” select, verify, and curate visuals but no longer solely control their distribution the way traditional gatekeepers did. 相似文献

This article examines the workflows, editorial guidelines, and managerial oversight of social media, particularly Twitter, at seven international news agencies. Through a series of in-depth interviews with news managers, social media producers, and public relations officials at Al Jazeera, CNN, Globo, Telecinco, RTVE, the US government's Office of Cuba Broadcasting, and Voice of America, the authors examined how these policies may affect the framing of news stories. Results indicated that social media resources are currently being used more for promotional and audience tracking purposes than for newsgathering, although the Office of Cuba Broadcasting departed somewhat from that model. 相似文献

The mere perception that news has given certain problems more coverage can lead the audience to assume that those problems are more important. Given that the news media, at times, obsesses over relatively trivial matters, and given that the audience is increasingly able to filter media exposure, it is worth asking what happens when audience members perceive that recent media coverage has not emphasized any very important problems. In such cases, audience members might assume that any problems facing the nation must not be particularly important. We explicate this attitude of political complacency, test whether perceived media agendas lacking important problems can influence it, and explore whether complacency helps explain political disengagement. We also explore whether these effects generalize beyond news, to new media gatekeepers such as Twitter. Two experiments tested effects of a perceived absence of important problems in recent news or Twitter content. In the case of news, but not Twitter, this increased complacency in both studies. Study 2 added a no-exposure control and found that effects on complacency were driven by the cueing of nonproblem stories, not by the absence of problem story cues. Both studies validated complacency as a predictor of political disengagement. 相似文献

As governments are increasingly turning to social media as a means of engaging the public, questions remain as to how they are actually using various social media platforms. Do specific platforms engender specific types of messages? If so, what are they, and how do they affect civic engagement, co-participation, and address citizen concerns? In this paper, we compare the use of Instagram and Twitter by ‘The Big Lift’, a bridge re-decking project completed by Halifax Harbour Bridges. Based on a content analysis of Instagram (n = 248) and Twitter (n = 1278) public posts, we found that Instagram was used as a more ‘informal’ narrative platform that promoted a clicktivist type of responses from the audience, whereas Twitter was a more ‘formal’ news platform that supported greater two-way communication between the organization and the audience. We conclude that by building and maintaining their active presence and following base on social media, and especially on Twitter, organizations can develop a capacity to address social concerns during disruptive events or infrastructure projects like ‘The Big Lift’. 相似文献

This study investigates networked framing of terrorism news in Twitter by distinguishing three proximity effects (geographic, social, and temporal proximity) on audience and media institutional frames (i.e., episodic/thematic and space frames), based on construal-level theory. An analysis of tweets during the Boston Marathon bombing and the Brussels Airport attack finds that institutional and audience frames show similarity but do not always converge on Twitter. Similarities in the audience and institutional frames are attributed to a universal human tendency for social categorization, inherent in the minds of not only ordinary citizens but also journalists. Proximity effects, however, were more salient on audience frames than on institutional frames. 相似文献

Why People Dual Screen Political Debates and Why It Matters for Democratic Engagement 总被引：1，自引：0，他引：1
Dual screening during televised election debates is a new domain in which political elites and journalists seek to influence audience attitudes and behavior. But to what extent do non-elite dual screeners seek to influence others, particularly their social media followers, social media users in general, and even politicians and journalists? And how does this behavior affect short- and longer-term engagement with election campaigns? Using unique, event-based, panel survey data from the main 2015 UK general election debate (Wave 1 = 2,351; Wave 2 = 1,168) we reveal the conditions under which people experience agency, empowerment, and engagement now that social media have reconfigured broadcast political television. 相似文献

Government agencies are directed to communicate objective and scientific information to the public, but studies show that political ideology may play a role in how much information governments provide. In this paper I argue that the ideology of a head administrator, and its alignment with agency mission, can restrict the kinds of information that government agencies provide, which may or may not amount to a type of regulatory capture. This impact may also be moderated by the specific media in which the communication takes place. I explore this theory via a case study of the United States Environmental Protection Agency online communication over a period of 32 months, during the years of 2013–2014, under the Democratic Administrator Gina McCarthy, and 2017–2018, under the Republican Administrator Scott Pruitt, via topical terms and document analyses of Twitter posts and web news releases. The information—topics, policies and issues—remain largely consistent across administrations and media channels, but notable distinctions are observed that point to the political ideologies of administrators in office, including a restriction of relevant scientific information on climate change during the misaligned administrator. Moreover, results show differences across media types which may reflect speed and popularity affordances of Twitter compared to website communication. I conclude by discussing the importance of policies to protect against ideological partisanship, and how social media may be better used as tools in government information policy and online communication. 相似文献

This study adopts a network analytic approach to understand media audiences in relation to media markets, bridging the literature on audience behavior and media economics. Using audience data in the Chinese and U.S. markets, we apply multi-level measures to compare audience fragmentation patterns, a key indicator of market structure, across television channels. Drawing on McQuail's four–stage fragmentation model, we find the Chinese television market exhibits the Core-Peripheral model where a few channels dominate the marketplace and the rest are viewed by niche segments of the audience. In contrast, the U.S. market represents the Pluralism model with extremely high levels of audience duplication across channels, suggesting overlapping patterns of exposure throughout the market rather than isolated segments. 相似文献

This research examined the ways in which academic librarians and users interact when using social media tools such as Twitter and Weibo as well as end-users' and librarians' perceptions of the types of interaction through social media. The study conducted an analysis of 1600 microblog posts sampled from twenty university library Weibo (Chinese Twitter) sites and twenty library Twitter sites in English-speaking countries. The results were compared using Chi-Square analysis. Results indicated that at present academic librarians in English-speaking countries use post information relevant to the library (news and events) and respond to information/research inquiries. And academic librarians in China are likely to use Weibo to communicate with users and to disseminate library news. Given the lack of previous research on how social media such as micro-blogging in general facilitates communication between librarians and library users in academic libraries between in English-speaking countries and China, this study provides valuable information concerning librarians' and end-users' interactions of information/knowledge sharing activities, which will enable libraries to be better positioned to promote user engagement through SNS usage. 相似文献

This study examines whether the characteristics of those who share news articles on social media influence the hostile media effect. In an experiment, participants read a news article shared by 1 of 4 Twitter users, 2 (Republican vs. Democrat) × 2 (21 vs. 503,000 followers). Consistent with the hostile media effect, both Republicans and Democrats believed that a news article shared by a Twitter user from an opposing political party was more biased than one shared by a Twitter user from the same political party. As the Twitter account had more followers, however, this effect was more prominent among Republicans and less prominent among Democrats. 相似文献

Twitter has become a global, social media platform that is reshaping the way journalists communicate, gather information, and disseminate news. This study builds on the relatively young field of research by using diffusion of innovation theory to gauge what factors influence the spread and adoption of Twitter. Case-study and in-depth interview methods were used in collecting data from 50 journalists at 4 metropolitan newspapers. Results show that the adoption and implementation of Twitter relies on peer pressure and coaching to get reluctant journalists to try Twitter. Adoption is then immediate because journalists see how Twitter is a gateway to new sources of information and story tips. Ultimately, journalists embrace Twitter because it provides instant gratification from followers, allowing them to share stories with a broader, global audience. 相似文献

This study employed the uses and gratification approach to investigate how journalists perceive relational satisfaction with the public on Twitter, specifically the associations between journalists’ motivations to use Twitter, their Twitter use, and their relational satisfaction with the public. Through a survey of South Korean journalists, this study revealed that journalists’ motivations for Twitter use are positively related to their job-related activities on Twitter (e.g., posting/sharing their news and interacting with audience), which consequently influences perceived relational satisfaction with the public. The findings provide new insight into an increasingly important part of the public’s engagement and news/information flows in the digital media environment. This study expands upon the literature by analyzing how journalists’ motivations for using Twitter and their job-related activities on Twitter are associated with relational satisfaction with the public. 相似文献

Twitter is currently one of the most popular outlets of so-called social media, Internet services that allow their users to communicate and share content in a variety of ways. As with the Internet itself, Twitter has been heralded to hold interesting possibilities within the context of journalism—potentially bringing journalists and their respective audiences closer to each other through supposedly common Twitter practices like @ messages and retweeting. This article presents a large-scale empirical study on Twitter use in the journalistic context. The aim is to assess patterns of journalist-audience interaction on Twitter. Specifically, the article outlines a structural analysis of Twitter use pertaining to the first season of the current events talk show Hübinette, which aired on Swedish public service television during the fall of 2011. Employing state-of-the-art approaches for data collection and analysis, the article shows that while traditional patterns of journalist-reader relationships are most common, some users are employing the Twitter platform in somewhat unforeseen ways. 相似文献

A content analysis of 4,507 tweets from 60 local news organizations in the United States was conducted to examine Twitter strategies used by the local news industry. Results indicate that local news organizations in the United States mainly used Twitter as an additional platform for news dissemination. While local TV stations and newspapers differed significantly in their use of tweet structures, content, and strategies, both followed the similar practices of their traditional media portals. In addition, the number of followers and total tweets of a news organization’s Twitter account, use of photos, hashtags, usernames, and tweet content predicted audience engagement with the site. Overall, local news organizations in the United States did not appear to use Twitter to cross-promote and/or supplement their traditional business practices. This research calls for more systematic, multi-dimensional social media management in local newsrooms. 相似文献

Many researchers have assumed that social media will reduce inequalities between elite politicians and those outside the political mainstream and that it will thus benefit democracy, as it circumvents the traditional media that focus too much on a few elite politicians. I test this assumption by investigating the association between U.S. Representatives using Twitter and their fundraising. Evidence suggests that (1) politicians' adoptions of social media have yielded increased donations from outside their constituencies but little from within their own constituencies; (2) politicians with extreme ideologies tend to benefit more from their social media adoptions; and (3) the political use of social media may yield a more unequal distribution of financial resources among candidates. Finally, I discuss the implications of these findings for political equality, polarization, and democracy. 相似文献

Twitter users see content mostly from the other users they select to follow. Networks of connected users on Twitter define the set of content to which each user is exposed. We developed a Selective Exposure Cluster (SEC) method to study these connected networks and their discussion patterns in Twitter. To illustrate the SEC method, we collected networks of connections among users who talked about a shared topic: the U.S. President's State of the Union speech in 2012. Cluster analysis was applied to identify subgroups of users who were densely interconnected. These users followed users from their own cluster more than they connected to users in other clusters. In each cluster, the primary distributors of information—the hub users—were identified, along with the hashtags, hyperlinks, and top-mentioned usernames in the content of the messages. Each of these indicators was labeled in terms of its political orientation. An analysis of the resulting patterns of selective exposure suggests that users participate in fragmented interactions and form divided groups in which people tune in to a narrow segment of the wider range of politically oriented information sources. We discuss the strengths and weaknesses of the proposed Selective Exposure Cluster method. 相似文献

This paper provides a general overview of the way local governments use Twitter as a communication tool to engage with their citizens. More concretely, it tries to identify factors associated with both the channel activity and citizen engagement, to understand the relationship between media type and citizen engagement and to analyse whether different content generated different levels of engagement. A sample of the 29 most populated Andalusian local governments is examined. The results show that the majority of Andalusian local governments have an official corporate Twitter account with certain level of activity. There is no, however, a significant relationship between the population of a municipality and its citizen's engagement, and there is a significant negative relationship between audience and engagement and between activity and engagement. The findings of the study also show the particular media and content types generate higher engagement than others. This paper contributes to the literature on social media and has practical implications for local governments. 相似文献

Focusing on the dataset dissemination structure on Twitter, this study aims to investigate how users of two different identities, scholars and the public, participate in the dissemination process. We collected 2464 datasets from Altmetric.com and used social network analysis to plot the graphs. From a macroscopic viewpoint, most datasets were diffused by viral dissemination (structure II) and mixed dissemination (structure III), and the diffusion level was fundamentally one or two levels. Based on the topics clustering results of the datasets, the majority were about open access, research data, and Altmetrics, as well as astronomy, biology, medicine, and environmental engineering. The dataset dissemination structure shared a little relationship with the research topic. From the microscopic viewpoint of parent nodes and child nodes, during the dataset dissemination, there were only marginally more Twitter users with scholar status than non-scholar ones, suggesting that compared with traditional academic accomplishments such as journal papers. However, the dataset seems to be more professional and targeted; significant audience beyond academics are also involved. During disseminating datasets on Twitter, most tended to be diffused among users of the same identity. However, a few non-scholars played crucial roles, such as super users and intermediaries. Overall, a considerable part of tweets and tweets of parent nodes with the ability to spread is primarily the tweets commented simultaneously forwarded (type II) are posted at the same time commented. Hence, this study underlines the significance of research data-sharing and social media's role in public participation in science. 相似文献
