This study examined how news organizations employed Twitter as a news source, based on information subsidy and gatekeeping perspectives. News content analysis from 7 major media entities in 2010–2011 demonstrated that journalists embraced Twitter as a new channel for information gathering. TV frequently cited Twitter as a sole or a primary source. However, despite active usage of Twitter overall, journalists in both TV and newspapers maintained conventional routines by relying primarily on Twitter accounts of official sources. The popularity of Twitter accounts, as indicated by the number of followers, did not contribute to attracting more attention from journalists.  相似文献

Social media rumors are improvised and expressive forms of public opinion that especially arise under uncertain sociopolitical situations. This study utilizes early rumor studies as theoretical framework for textual analysis of Twitter public opinion. A content and semantic network analysis of Twitter messages spread during Korean saber rattling in 2013 was conducted for understanding public opinion in an uncertain context. The results show that, while non-rumor narratives focus on policy-level responses to the threat situation in a similar manner to institutionalized opinion polling, rumors are less concerned with official responses, instead reflective of hegemonic tensions between anti-leftwing political sentiments and the counteractive accounts. Some rumors reveal the public's coping with fears in the form of humor, guesswork, or wishes. Online rumor analysis helps understand how the society's collective memories interact with the current situational uncertainty in shaping public opinions and sentiments.  相似文献

This study presents an analysis of Twitter networks from academic libraries housed in medium-sized, primarily undergraduate universities. Previous investigations on this topic have used networks of followers, i.e. attention, to show that accounts associated with a library's home institution are the prime influencers in library Twitter networks. That is, they are in key positions to disseminate library-related information. The library itself was found to be positioned to contribute to the institution-wide conversation as well. Networks of followers, however, are susceptible to unwanted influence from inactive users. The present study utilizes networks constructed from tweeting behavior to identify influencers. These networks are, thus, insensitive to inactive followers. The results are compared to those of the previously published follower networks. The behavior networks are significantly smaller and contain far fewer interactions than the follower networks; however, institutional accounts are found to be the principal influencers in these networks as well. Additionally, the social network analysis allows for the quantification of relationship strengths. The closest relationships are between library/institutional and library/student accounts. The former demonstrates that the libraries are active participants in the university-wide exchanges on Twitter and the institutional accounts often include the libraries in their messages.  相似文献

Social media has become a key medium for discussion and dissemination of news stories, fuelled by the low barrier to entry and the ease of interaction. News stories may be propagated through these networks either by official news organisation accounts, by individual journalists or by members of the public, through link sharing, endorsing or commenting. This preliminary research aims to show how computational analysis of large-scale data-sets allows us to investigate the means by which news stories are spread through social media, and how the conversation around them is shaped by journalists and news organisations. Through the capture of more than 11 million tweets relating to 2303 Twitter accounts connected to journalism and news organisations, we are able to analyse the conversation within and around journalism, examining who spreads information about news articles and who interacts in the discussion around them. Capturing the tweets of news organisations and journalists and the replies and retweets of these micro-blogs allows us to build a rich picture of interaction around news media.  相似文献

American sports writers' use of social media as a newsgathering tool has influenced journalism practice, further complicating the industry's abstract definition of “professionalism.” This study builds on a pilot study published in the fall 2011 issue of Journal of Sports Media, which assessed print sports journalists' use of social media. In the current study, a survey was administered to 77 full-time print sports journalists who cover professional sports. This paper seeks to extend the pilot study and previous professional research in two ways: firstly, to assess how this specific subgroup of sports writers use Facebook and Twitter to gather information; and secondly, to analyze how these sports writers define “professionalism” and what industry factors correlate with chosen definitions, such as newspaper circulation and work superiors' attitudes toward social media. Cross-tabulations and chi-square tests were used to test hypotheses. Cramer's V or Phi, depending upon the cross-tabulation, were used to measure relationship strength. Results suggest this subset of sports writers more often uses Twitter for newsgathering purposing than Facebook. There is also a strong relationship between the frequency of Twitter usage and the definition of professionalism chosen; circulation size and instances of directly quoting from athletes' social media accounts; and age and Twitter usage.  相似文献

This study focused on call-in talk radio because it provides a unique opportunity to test competing hypotheses drawn from two different perspectives about the appeal of media programming. A good deal of research on call-in talk radio grows from a deficiency perspective, which holds that people seek out media content to fill gaps in their lives. More recent research, however, suggests that, like the selection of other media content, the appeal of talk radio lies in enrichment, or its ability to provide content for specialized interests. A random telephone survey tested competing hypotheses that compared listeners to call-in talk radio with nonlisteners. For the most part, the results supported an enrichment explanation. Compared to nonlisteners, listeners to call-in talk radio listened to the programs for information, perceived themselves as more mobile, and valued arguments. Compared to nonlisteners, callers to the programs were also more civically engaged. Moreover, listening to various subformats of talk radio programs was also likely to signal enrichment.  相似文献

ABSTRACT

This article details the various forces that shaped public radio station KEXP’s evolution from the 70s to today. It addresses the ways that Seattle’s specific cultural, economic, and technological advantages enabled it to take on its current form as a key presence in global pop music curation and discovery. It argues that the station’s progression thus represents a potential model for other legacy public radio stations in an era of diminishing public and institutional funding. However, this approach’s viability will depend upon how effectively stations are able to leverage their local communities to compete in the networked digital media paradigm.  相似文献

Media outlets and platforms in contemporary societies do not operate in isolation, but are interconnected with each other in various ways. The influence and significance of a medium can therefore depend on what Bolter and Grusin (1999 Bolter , J. D. , & Grusin , R. ( 1999 ). Remediation . Cambridge , MA : MIT Press . [Google Scholar]) labeled “remediation,” that is, the processes through which a medium is represented by other media. Content adaptation—the selective appropriation of the contents of another medium—is a specific means of remediation. This article applies these theoretical principles to the study of talk radio in Hong Kong. It examines how newspapers appropriate the contents of political talk radio and how content adaptation by the press affects people's perceptions of talk radio. Empirically, a content analysis shows that newspapers regularly cover talk radio contents, but the coverage is affected by the journalistic paradigms the newspapers adopt. Based on the content analysis, hypotheses about the relationships between news consumption, talk radio listening, and perceived value of talk radio are set up and tested by data from a representative survey (N = 862). The findings confirm the presence of “content adaptation effects.”  相似文献

Although much of the world basks in the glory of the Internet and availability of competitive media outlets, Africa's media landscape remains bleak. Radio, newspapers, and television continue to be government controlled: Radio's power to reach the masses suggests that many governments may never fully privatize the electronic media. Zambia has experienced growth of private media. Private radio stations in Lusaka have attracted nearly half of the listening audience away from government radio. Listeners rate radio as their most important source for news and the medium is highly regarded for accuracy and fairness. Yet these few private stations lack national coverage and political and economic clout to challenge government broadcasting.  相似文献

This study examines how people perceive the influence of political talk radio in Hong Kong. Theoretically, the study focuses on the influence of message-attitude congruence, that is, the situation in which a person's opinions or attitudes are consistent with the viewpoints promulgated by media messages, on the third-person perception. It is argued that message-attitude congruence provides a situation in which people may attribute their attitudes partly to media influence. Hence message-attitude congruence is expected to relate to increased levels of perceived media influence on self, and thereby weaken the size of the third-person differential. Moreover, it is hypothesized that attribution of media influence should be more likely when people perceive the media influence as desirable and when there is the absence of alternative sources of influence. These arguments were tested with a telephone survey (N = 800) in Hong Kong, where political talk radio has been a prominent medium in the past decade. The results support the theoretical arguments and contribute to our understanding of the significance of the medium in the city. The broader theoretical implications of the findings are also discussed.  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

Using data for 320 radio stations operating in the 50 largest Arbitron metro radio markets during 2004 that offered at least some programming in 1 or more of 19 different foreign languages, strongly positive statistical relations were found between the size of foreign language populations in the radio market and the amount, or variety, of radio programming in their respective language that is available. A preference externality effect was also found: consistently negative relations between the variety of foreign language programming available and size of the English language population. Similar results were found for a measure of programming quality: the percentage of news and talk programming that is locally produced. Conventional wisdom that minority populations tend to be “underserved” by media is generally supported.  相似文献

This paper provides a historical perspective on the intersection of media, popular culture, and nationalism through a study of the broadcasting policies and programs of one of Mexico's earliest government radio stations. This study analyzes the musical programs that formed the centerpiece of government radio programming in order to evaluate the racial and class ideologies imbedded in the nationalist discourse of state broadcasters. By viewing these government programs through the lens of a broader literature on nationalism in the Third World and among diasporic communities, it is possible to identify a fundamental tension in Mexico's official nationalism between a search for the roots of an “authentic”; ethnic identity, and a need to position Mexican culture within the constellation of Western “civilization.”; Finally, this paper investigates audience reactions to state broadcasts in order to explore the meaning of early broadcast nationalism for Mexico's radio listeners.  相似文献

For decades, radio was primarily a hidden or unseen medium to listeners. In recent years, digital technologies have transformed radio to a medium that can both be seen and heard. In particular, visuals on social media have given audiences a real-time glimpse of broadcast operations and talent, while enhancing interaction with stations. This study examined how commercial stations across the United States portrayed themselves through posts on Instagram. Using a qualitative methodology and social semiotic theory, results of the study revealed two dominant themes of station posts—station promotion and community—that signified the essence of radio stations.  相似文献

A content analysis examined the Twitter sites of 488 local television stations in the United States, based on a strategic and tactical model of media promotion. One finding of the study was that news stories were the most frequently occurring items on the sites. However, stations that offered news items also seldom promoted their regular newscasts. Overall, stations did not appear to use Twitter to direct viewers to the station's on-air programming.  相似文献

ABSTRACT

This study addresses the issue of sampling biases in social media data-driven communication research. The authors demonstrate how supervised machine learning could reduce Twitter sampling bias induced from “proxy-population mismatch”. Particularly, this study used the Random Forest (RF) classifier to disentangle tweet samples representative of general publics’ activities from non-general—or institutional—activities. By applying RF classifier models to Twitter data sets relevant to four news events and a randomly pooled dataset, the study finds systematic differences between general user samples and institutional user samples in their messaging patterns. This article calls for disentangling Twitter user samples when ordinary user behaviors are the focus of research. It also builds on the development of machine learning modeling in the context of communication research.  相似文献

Libraries are offering more services through social media Web sites like Twitter and Facebook, and this presence online is encouraging more conversation between libraries and patrons, including collection development requests. A review of popular Twitter and Facebook library profiles reveals the most successful accounts to be those where the library actively engages its users online. Through these media, libraries can have direct, immediate conversations with patrons that result in patron-initiated material requests.  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
