The success of government social media relies on citizens' continual usage. Through the theoretical lens of the Uses & Gratifications theory, we develop a research model for mobile government microblogging services (GMS) continuance intention, in which citizens' perceived integration of online and offline social lives and internet censorship are incorporated. Based on data from 629 mobile GMS users in China, the results of the structural equation modeling analysis show that perceived online–offline integration has a significant and positive effect on the three dimensions of gratification: content gratification, social gratification, and process gratification, which jointly influence mobile GMS continuance. Citizens' perceived internet censorship negatively affects their mobile GMS continuance. These results might provide understanding about the unique aspects of government social media, especially in the context of internet censorship. 相似文献

Information control processes designed to prioritize the most relevant information are important for enhancing the service experience of users. Gatekeeping is the process of filtering and disseminating information in online information services. This study investigates the effects of gatekeeping activities on information services and the resulting impact on the value of such services from a user's perspective in an information service environment characterized by online and offline transactions. Various hybrid gatekeeping activities are derived through focus group interviews with information services planners. A survey of information service users reveals values that could be obtained from the information services. The results of these two data gathering tools suggest an information service framework for hybrid environments. The findings enable the development of value-added information services for users through efficient information control in hybrid online and offline environments. 相似文献

This study investigates how social factors affect Taiwanese Internet users’ dual screening use and its impact on online and offline political participation. The Web survey recruits 961 dual screen users. Structural equation modeling results show that bridging social capital and perceived social presence are significantly associated with dual screening use. Dual screening is positively related to online and offline political participation. Dual screening use strongly influences offline political participation when mediated by online political participation. Moreover, alternative media trust is positively related to online political participation, whereas mainstream media trust shows a negative association. 相似文献

Although there is an increasing amount of research on social support in cyberspace, little is known about how Internet technologies influence social support among people who share offline personal relationships. The current study examined how friends' instant messenger (IM) status might influence individuals' coping and support-seeking, and what mechanisms could account for those effects. Four hundred and ninety-four college students read and responded to a hypothetical scenario in which they logged onto IM after experiencing a stressful situation. Participants perceived higher levels of self-efficacy, greater stress decrease, and greater likelihood of seeking support from a friend when the friend was said to be online than offline. Perceived social presence mediated the influence of a friend's online status on participants' coping and likelihood of seeking support from the friend. 相似文献

Interactions in online environments are influenced by many of the same gender and sex-role stereotypes that people use in offline interactions. However, less research has examined systematically how the traits of an avatar and the avatar's user interact to influence stereotypical responses in virtual spaces. A field experiment manipulated avatar attractiveness, avatar sex, user sex, and favor difficulty to measure responses to a requested favor across 2,300 interactions in an online game. Attractive avatars received more help than less attractive avatars, but female users received less help than male users when represented by avatars that were less attractive or male. 相似文献

One aspect of the mediatization of politics is the idea that political actors adapt to the communication logic of news media to gain, for example, news media attention. Currently, this process may be influenced by the diffusion of the internet as a political communication channel, especially because online communication provides a new opportunity for political actors to communicate directly with citizens. Thus far, the adaptation to media logic by political parties has mainly been examined in the context of election campaigns. In order to transfer these findings to regular political communication, this study compares the use of media logic in the mass media and in direct political communication channels online and offline about the United Nations Climate Change Conferences 2011 and 2012. A quantitative content analysis of the conference protocols (input) and the presentation of the conference results in the seven most frequently used German offline news outlets (print and TV) and their online counterparts, as well as political offline and online communication channels like parliamentary speeches and websites of the six parties represented in the German parliament (output), was conducted. Results show that in the context of regular political communication, political actors seem to follow media logic to a lesser extent than in the context of election campaigns. Thus far, the influence of online communication on the mediatization of politics seems to be rather marginal. The causes and consequences of these findings are discussed. 相似文献

By analyzing the Citizenship Involvement Democracy survey conducted on American citizens, this paper investigates categorical and demographic disparities between online and offline political participants and examines the two-sided effects (reinforcing and mobilizing) of the internet on political participation. The analysis presents three main findings. First, those who participate in online political activity do not differ categorically from those who conduct their political activity offline. Second, cross-group differences in how actively individuals participate in political activity make little distinction between offline and online modes. There is a trade-off between the generational gap in online political activity and the racial gap in offline political activity, but the gap in political participation between the socioeconomically advantaged and their counterparts appears in both online and offline political activities. Finally, the internet plays a dual role in mobilizing political participation by people not normally politically involved, as well as reinforcing existing offline participation. 相似文献

This study considers fitness-tracking applications as settings for communicative performances. Qualitative interviews and observations with 41 users of a cycling-focused fitness application revealed communicative themes of qualifying, social sharing, and withholding. Users also assessed other members through social-group comparing and upward comparing. This study develops theory by revealing how individuals use the technology to communicate about their physical acts, and how the context of use facilitates organizing processes. We argue that use of this fitness application extends our understanding of how communication can constitute a community of practice (CoP; Brown & Duguid, 1991; Lave & Wenger, 1991). Primarily, the hybrid online/offline nature of Strava complicates the traditional understanding of communication and CoPs. 相似文献

This article examines if patterns in online news seeking privilege stories featuring more linguistic markers of partisan affect than those positioned by traditional gatekeepers on the print front page. Online “most-read” and print front-page stories covering 8 weeks of the 2012 presidential campaign were submitted to computer-assisted text analysis (n = 302). Guided by research on online and partisan affect, this study hypothesizes that (a) “most-read” stories will feature more supportive language than stories placed on the front page by traditional gatekeepers when the news outlet has a reputation for supporting the incumbent party; and (b) “most-read” stories will feature more antagonistic language than those placed on the front page by traditional gatekeepers when the news outlet has a reputation for supporting the challenger party. The findings show how online audiences opted for stories that featured more linguistic markers of preferred partisan affect than journalists and editors placed on Page One. 相似文献

Online display advertising is a multi-billion dollar industry where advertisers promote their products to users by having publishers display their advertisements on popular Web pages. An important problem in online advertising is how to forecast the number of user visits for a Web page during a particular period of time. Prior research addressed the problem by using traditional time-series forecasting techniques on historical data of user visits; (e.g., via a single regression model built for forecasting based on historical data for all Web pages) and did not fully explore the fact that different types of Web pages and different time stamps have different patterns of user visits. In this paper, we propose a series of probabilistic latent class models to automatically learn the underlying user visit patterns among multiple Web pages and multiple time stamps. The last (and the most effective) proposed model identifies latent groups/classes of (i) Web pages and (ii) time stamps with similar user visit patterns, and learns a specialized forecast model for each latent Web page and time stamp class. Compared with a single regression model as well as several other baselines, the proposed latent class model approach has the capability of differentiating the importance of different types of information across different classes of Web pages and time stamps, and therefore has much better modeling flexibility. An extensive set of experiments along with detailed analysis carried out on real-world data from Yahoo! demonstrates the advantage of the proposed latent class models in forecasting online user visits in online display advertising. 相似文献

ABSTRACT As the World Wide Web has advanced since its inception, librarians have endeavored to keep pace with this progress in the design of their library Web pages. User recommendations collected from focus groups and usability testing have indicated that the University of Scranton's Weinberg Memorial Library's Web site was not working as intended, and the library's home page, in particular, was cluttered. Focus groups indicated that the process of accessing the library's databases from off-campus took too many steps, key resources were not located in key areas of the page, links were too close together, and the font was too small. Library staff determined it was necessary to rethink and redesign its pages. Self-reports from focus groups were insufficient to get at the mechanics of Web page use. Through usability testing, librarians were able to observe students and faculty completing simple research and directional tasks. Before “going live” with the new page in January 2007, users who had participated in the focus groups and in the usability testing were surveyed about the redesigned library Web page. The users indicated that the new Web page was less confusing, easier to use, and somewhat more intuitive than the previous library Web page. Web sites are always works in progress, and academic librarians should be proactive about making changes to their library Web sites to take advantage of emerging technology and to meet user expectations. 相似文献

Online daters construct their profiles to attract potential partners and viewers’ assessments are based on the content of dating profiles. However, little is known about the mechanisms or nature of the associations that connect variations in profile content to outcomes. This study examined the presence of selective self-presentation (SSP) and warranting content as predictors of viewers’ impressions and intentions to act on dating profiles. A national sample of online daters (N?=?316) provided their impressions and intended outcomes after viewing manipulated dating profiles. Results indicate that high levels of SSP decrease intentions to act on a dating profile because users find these profiles to be less socially attractive, whereas profiles with high warranting value increase positive outcomes by eliciting trust. 相似文献

The spiral of silence (SoS) framework elaborates the factors that determine whether individuals are willing to express their opinions in public. Although previous scholarship has examined differences in between face-to-face and computer-mediated communication, research studies have rarely tested how perceived affordances of the channel influence whether individuals express opinions or self-censor. In this study (N = 399), we examine several propositions of SoS within the context of discussing police discrimination on Facebook. To extend the theory’s relevance to social networking sites, we examined how users’ perceptions of network association, social presence, anonymity, and persistence related to opinion expression. Findings indicate support for some of the theory’s original tenets, as well as the role of multiple perceived affordances in determining whether people will express an opinion to their online social network. We discuss the implications for measuring and understanding political expression and silencing on social media as well as offline. 相似文献

Abstract For decades libraries have created subject guides to assist users in navigating their collections. These guides are universally accepted as a core library product of high value across all user groups. No longer confined to paper stashed in kiosks and on counter tops, subject guides are now available online from library Web sites and often emphasize and link to other Web resources. Typically, a link on the library's home page directs users to a Subject Guide List which offers active links to the topical guides. But are these links and listings sufficient to attract users? This article describes the results of a study to catalog selected subject guides on U.S. and British History and analyze usage statistics before and after cataloging. It appears that the library catalog is effective at exposing subject guides and should be considered an additional point of access amidst a growing number of discovery mechanisms. 相似文献

As academic libraries create online learning objects, it is important to consider whether such resources actually reach and answer the questions of intended users. This study considers three points of inquiry for one academic library: How its users make their way to the library's tutorials; user preference for searching or browsing for resources, when given both modes of access; and the kinds of online learning objects or tutorials users are seeking. A close examination of Web analytics and users’ search terms within the tutorials interface helped to illustrate patterns of access and highlighted users’ needs for tutorials and online learning objects. 相似文献
