This study investigates the effects of social media marketing of alcoholic beverages using a 2 (likes: low vs. high) × 2 (shares: low vs. high) × 3 (display ad type: alcohol ad vs. antibinge drinking PSA vs. local bank) × 6 (status update repetitions) experimental design. The study examines how evaluations of alcohol marketing status updates and display advertisements predict social media users’ intentions to consume alcohol, as a function of message virality and display ad type. Participants’ viral behavioral intentions (intentions to like, share, and comment on) for status updates were strongest in predicting intentions to consume alcohol, and this relationship was strongest when the Facebook status update had high likes and shares. The article argues that alcohol marketing on social media reflects a social norm of alcohol consumption, which leads users to consume more alcoholic drinks. Findings are discussed within the framework of persuasion theories and policy changes regarding regulation of alcohol marketing on social media. 相似文献

Facebook is an extremely popular social networking site with college students. Many academic libraries have created their Facebook profiles to reach more users. This article studies the Facebook presence of Association of Research Libraries (ARL) member institutions, particularly academic ones. Their Facebook pages are analyzed comprehensively in terms of content, launch time, and popularity. The majority of these libraries maintain at least one Facebook page whose content typically focuses on library events, resource updates, etc. 相似文献

The work presented here characterise the engagement of one university library with two social media platforms popular with academic libraries. The collected data are analysed to identify the forms of Twitter and Facebook activity that engage library stakeholders in social media conversations. Associations were observed between: i) directed tweets from the library and mentions of the library by others on Twitter; and ii) comments from the library and comments from others on Facebook. Three broad classes of Twitter user interacting with the library were revealed: i) accounts strongly linked to the library with multiple to/from tweets; ii) those weakly linked to the library with, typically, a single tweet; and iii) those indirectly linked to the library through tweets mentioning the library and sent by other users. Two divergent forms of Facebook interaction with the library were highlighted: i) a library post generating a large sequence of comments, typically in response to a competition/challenge; and ii) a library post with no comments, typically a photo post or a post inviting readers to click a link to find out more about an event/service. The work presented here is an initial investigation that provides useful insights, and offers a methodology for future research. 相似文献

ABSTRACTThis experimental study examined the impact of posting different types of tweets on a journalist’s perceived credibility. Three-hundred-and-eighty-seven participants were randomly assigned into one of three groups. One group saw tweets from a journalist that were about the journalist’s personal life, another group saw tweets from the same journalist that were written objectively about news stories, and the third group saw tweets from the same journalist that contained the journalist’s opinion regarding news stories. Participants who read the personal tweets about the journalist’s life rated the journalist highest in perceived credibility. The perceived credibility of the journalist was ranked significantly lower by participants who read the tweets that only contained the journalist’s opinion. Participants were also asked to rate the credibility of the organization for which the journalist worked. The perceived credibility of the organization was rated significantly higher by those who read the objective tweets. Organizational credibility was rated lowest by those who read the tweets that contained the journalist’s opinion. This study has important implications for journalists who use Twitter and wish to improve their personal and organizational perceived credibility. 相似文献

On November 30, 2014, five African American St. Louis Rams players locked hands and displayed a “hands-up” gesture during player introductions in response to racial tensions in Ferguson, Missouri, emanating from the Michael Brown case. This act generated significant media attention and prompted discussions via Facebook and Twitter. Two notable venues on social media for these conversations were the “Boycott the St. Louis Rams” Facebook page and the Twitter hashtag #BoycottRams. A thematic analysis of 1,019 user-generated Facebook comments and 452 tweets was conducted through the lens of social identity threat management. Six primary themes emerged: (a) renouncing fandom, (b) punishment commentary, (c) racial commentary, (d) general criticism, (e) attacking other group members, and (f) presenting the “facts” of the case. The results suggest that social media sites such as Facebook and Twitter serve as forums where group members discuss and debate challenges to group values and promote action steps that can mitigate social identity threats. This form of protest holds implications for minority athletes’ activism efforts and sport organization administrators. 相似文献

Language distribution in scientific communication reflects the influence of different languages on science in global perspective. The study, based on over 450 thousand scientific tweets of all publications indexed by Scopus in June 2015, reveals the language distribution in informal scientific communication. Moreover, this result is compared with the language distribution in formal scientific communication reflected in scientific publications. Results show: (1) The language of scientific tweets is concentrated in English (91%), Japanese (2.4%) and Spanish (1.7%), while the language of scientific publications is concentrated in English (90.6%), Chinese (5%) and German (1.1%). (2) Both scientific tweets and scientific publications present disciplinary differences in language distribution, reflecting the different amount of attention that authors of different languages have on certain disciplines. (3) Except Saudi Arabia, investigated countries all over the world, regardless of whether their native language is English or not, all have English scientific tweets in the dominant position. For the vast majority of these countries, the native language scientific tweets only rank the second position. (4) Overall, 26% of tweeters use more than one language to tweet scientific products, while 49% of scientific tweeters tweet everything in English only. The results indicate that English has undoubtedly become the lingua franca in informal scientific communication. 相似文献

Recently, two new indicators (Equalized Mean-based Normalized Proportion Cited, EMNPC; Mean-based Normalized Proportion Cited, MNPC) were proposed which are intended for sparse scientometrics data, e.g., alternative metrics (altmetrics). The indicators compare the proportion of mentioned papers (e.g. on Facebook) of a unit (e.g., a researcher or institution) with the proportion of mentioned papers in the corresponding fields and publication years (the expected values). In this study, we propose a third indicator (Mantel-Haenszel quotient, MHq) belonging to the same indicator family. The MHq is based on the MH analysis – an established method in statistics for the comparison of proportions. We test (using citations and assessments by peers, i.e. F1000Prime recommendations) if the three indicators can distinguish between different quality levels as defined on the basis of the assessments by peers. Thus, we test their convergent validity. We find that the indicator MHq is able to distinguish between the quality levels in most cases while MNPC and EMNPC are not. Since the MHq is shown in this study to be a valid indicator, we apply it to six types of zero-inflated altmetrics data and test whether different altmetrics sources are related to quality. The results for the various altmetrics demonstrate that the relationship between altmetrics (Wikipedia, Facebook, blogs, and news data) and assessments by peers is not as strong as the relationship between citations and assessments by peers. Actually, the relationship between citations and peer assessments is about two to three times stronger than the association between altmetrics and assessments by peers. 相似文献

This research explored the perceptions of university students about the credibility of information being shared on Facebook. The data were collected using an online questionnaire from university students who were Facebook users. A total of 325 usable responses were received which were analyzed using SPSS. The results revealed that these students perceive information shared on Facebook as credible and of good quality. The source credibility, medium credibility, and information quality had positive and significant relationships with each other. The age, social background, and educational level of students appeared to predict the credibility of information shared on Facebook. These results are useful for information professionals and social media managers in extent to understand and cater to the demands of information consumers. These findings would also be helpful for teachers, information providers, and researchers to understand the perspectives of developing countries' students on the credibility of social media information. Furthermore, this study is supposed to be a valuable addition in existing literature which could provide guidelines for novice researchers, interested in exploring the area, especially in the context of Facebook users in a developing country's context. 相似文献

实证表明新冠肺炎疫情下公众选择不同传播渠道产生的"自我卷入"程度不一:短视频、微博(或微信)、新闻类APP等移动新传播渠道给公众造成的恐惧感更为显著;电视(或广播)等传统渠道更能影响公众的应急反应,让公众主动采取防护措施,积极进行自我保护和积极应对;但公众在权威信息、疫情进展上对电视(或广播)等传统渠道的期望值更高。主流媒体应从把控信息源头、创新表达形式、布局好舆情监测机制、做好媒体议程设置等四个方面来提高自身公信力,提高公众对主流信息的"自我卷入"程度,以防范可能出现的"信息疫情",维护社会秩序健康稳定。 相似文献

People spend an increasing amount of time using social media systems to network, share information, learn, or engage in leisure activities (e.g., gaming). Libraries too are establishing a social media presence to promote the library and provide services to user populations through the social media systems the users frequent. This study explores Twitter uses by six large academic libraries and factors that make library tweets useful. 752 tweets were analyzed by topic to develop a subject typology of library tweets. In addition, tweets and Twitter user characteristics were analyzed to explore what makes library tweets useful, as measured by the number of retweets and favorites received. Content analysis of the samples of library tweets revealed nine content types, with the event and resource categories being the most frequent. In addition, the analysis showed that tweets related to study support services and building and maintaining connections with the library community were the most frequently retweeted and selected as favorites. The presence of a URL in the tweet was positively associated with the number of retweets, and the number of users followed was positively associated with the number of favorites received. Finally, a negative correlation was found between the account age and number of favorites. 相似文献

ABSTRACT This experimental study examined whether stories presented on Facebook that appeared to be from a news organization were rated as higher in perceived credibility than stories that appeared to be from a non-news organization. One-hundred-and-seven participants took part in the online study. One group saw stories that appeared to be from a news organization and another group saw the same stories that appeared to be from a non-news organization. Both groups rated the stories the same in terms of perceived credibility. The study also found that the higher the participants rated the stories in terms of perceived credibility, the higher they rated the organization’s perceived credibility. These findings point to potential implications for traditional journalistic outlets regarding their ability to be seen as credible, reliable online news sources—particularly through a social media platform like Facebook. 相似文献

In this paper, we examine data from a 2011 survey of grassroots (or local) governments in the United States with respect to their adoption of social media (e.g., Facebook, Twitter, YouTube, blogs, and Flickr) especially to ascertain the drivers of local government social media adoption and whether the drivers are similar to or different from the drivers of e-government adoption. We also address whether the adoption of social media portends a move by local governments from Web 1.0 to Web 2.0. 相似文献

Facebook is challenging professional journalism. These challenges were evident in three incidents from 2016: the allegation that Facebook privileged progressive-leaning news on its trending feature; Facebook’s removal of the Pulitzer Prize-winning “Napalm Girl” photo from the pages of prominent users; and the proliferation of “fake news” during the US presidential election. Using theoretical concepts from the field of boundary work, this paper examines how The Guardian, The New York Times, Columbia Journalism Review and Poynter editorialized Facebook’s role in these three incidents to discursively construct the boundary between the value of professional journalism to democracy and Facebook’s ascendant role in facilitating essential democratic functions. Findings reveal that these publications attempted to define Facebook as a news organization (i.e., include it within the boundaries of journalism) so that they could then criticize the company for not following duties traditionally incumbent upon news organizations (i.e., place it outside the boundaries of journalism). This paper advances scholarship that focuses on both inward and outward conceptions of boundary work, further explores the complex challenge of defining who a journalist is in the face of rapidly changing technological norms, and advances scholarship in the field of media ethics that positions ethical analysis at the institutional level. 相似文献

ABSTRACTWhile Facebook is an important distribution channel for today's media houses, there is a lack of research on how news outlets choose to present their stories in social media. The present study aims to narrow this gap by analysing two weeks of Facebook updates by the Norwegian tabloid Dagbladet and the public-service broadcaster NRK and comparing them to the corresponding stories on their news sites. An important objective is to uncover if and how the Facebook updates depart from established text norms for online papers. The method is triangulated. A quantitative content analysis reveals that newsrooms tend to utilize a wider range of speech acts when writing presentations specifically for Facebook. A follow-up qualitative analysis identifies five rhetorical strategies for unique promo texts on Facebook: adding emojis, posing questions, making requests, expressing emotions and stating subjective points of view. Qualitative interviews with responsible journalists confirm that these strategies are more common the less controversial the stories are. However, the newsrooms have few explicit guidelines for when it is acceptable to transgress traditional journalistic text norms. The findings are summarized in a model that connects the continuum of decreasing story controversy to a corresponding continuum of increasingly interpretative and subjective rhetoric. 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

This article presents a structure-content framework to characterize social media engagement between government and the public because related scholarship fails to adequately link the concepts. The term structure refers to the flow of information—or the direction of messages from one type of account to another (e.g., a government agency to the public or vice versa) and the extent to which they interact. The term content represents the messages' intended goals and meaning. This framework integrates both concepts, notably the communication modes model (an example of structure) with content categories such as transparency, symbolic presentation, customer service, coproduction, and citizen participation. Because it is more comprehensive than typologies focused on either concept alone, the article more thoroughly conveys the complexity of available engagement opportunities. Facebook data from Hurricane Florence exemplify the model and account for both routine and critical operating conditions. 相似文献

Credibility-inspired ranking for blog post retrieval 总被引：1，自引：0，他引：1
Credibility of information refers to its believability or the believability of its sources. We explore the impact of credibility-inspired indicators on the task of blog post retrieval, following the intuition that more credible blog posts are preferred by searchers. Based on a previously introduced credibility framework for blogs, we define several credibility indicators, and divide them into post-level (e.g., spelling, timeliness, document length) and blog-level (e.g., regularity, expertise, comments) indicators. The retrieval task at hand is precision-oriented, and we hypothesize that the use of credibility-inspired indicators will positively impact precision. We propose to use ideas from the credibility framework in a reranking approach to the blog post retrieval problem: We introduce two simple ways of reranking the top n of an initial run. The first approach, Credibility-inspired reranking, simply reranks the top n of a baseline based on the credibility-inspired score. The second approach, Combined reranking, multiplies the credibility-inspired score of the top n results by their retrieval score, and reranks based on this score. Results show that Credibility-inspired reranking leads to larger improvements over the baseline than Combined reranking, but both approaches are capable of improving over an already strong baseline. For Credibility-inspired reranking the best performance is achieved using a combination of all post-level indicators. Combined reranking works best using the post-level indicators combined with comments and pronouns. The blog-level indicators expertise, regularity, and coherence do not contribute positively to the performance, although analysis shows that they can be useful for certain topics. Additional analysis shows that a relative small value of n (15–25) leads to the best results, and that posts that move up the ranking due to the integration of reranking based on credibility-inspired indicators do indeed appear to be more credible than the ones that go down. 相似文献

Social media use by government: From the routine to the critical 总被引：1，自引：0，他引：1

Social media and online services with user-generated content (e.g., Twitter, Facebook, Flickr, YouTube) have made a staggering amount of information (and misinformation) available. Government officials seek to leverage these resources to improve services and communication with citizens. Significant potential exists to identify issues in real time, so emergency managers can monitor and respond to issues concerning public safety. Yet, the sheer volume of social data streams generates substantial noise that must be filtered in order to detect meaningful patterns and trends. Important events can then be identified as spikes in activity, while event meaning and consequences can be deciphered by tracking changes in content and public sentiment. This paper presents findings from a exploratory study we conducted between June and December 2010 with government officials in Arlington, VA (and the greater National Capitol Region around Washington, D.C.), with the broad goal of understanding social media use by government officials as well as community organizations, businesses, and the public at large. A key objective was also to understand social media use specifically for managing crisis situations from the routine (e.g., traffic, weather crises) to the critical (e.g., earthquakes, floods). 相似文献
