Cultural differences in social media use, privacy, and self-disclosure : research report on a multicultural study

This research report presents comparative results from five nations (United States of America, United Kingdom, Germany, the Netherlands, and China) with regard to social media use, self-disclosure, privacy perceptions and attitudes, and privacy behavior in online environments. The data stemmed from an online survey that was conducted from November, 2011, to December, 2011. Across all five nations, N = 1,800 participants completed the survey. The findings suggest that a broad differentiation between Western and Eastern cultures only partly accounted for differences in social media use and privacy behavior. Rather, the results of this report suggest that European countries (United Kingdom, Germany, and the Netherlands) share similar privacy perceptions and show similar behavioral patterns. Non-European cultures (the USA and China) on the other hand, use social media differently. Participants from European countries had generally smaller audiences on social network sites and microblogging platforms, tended to limit the visibility of their postings and profile information more, and used more privacy settings to safeguard their privacy. In particular, German social media users seemed to be guarded, protective, and rather reluctant to participate in online communication. Users from the US, on the other hand, rated privacy-related behavior as less risky and were hence less likely to imply sophisticated privacy strategies. Apart from these findings, the report also shows that there are more commonalities than differences. People from all five countries think that it is important to protect privacy. Most users consciously decides what to share and what not to share. Accordingly, social media users do not always share intimate and detailed information about their lives

Beyond the culture effect on credibility perception on microblogs

We investigated the credibility perception of tweet readers from the USA and by readers from eight Arabic countries; our aim was to understand if credibility was affected by country and/or by culture. Results from a crowd-sourcing experiment, showed a wide variety of factors affected credibility perception, including a tweet author's gender, profile image, username style, location, and social network overlap with the reader. We found that culture determines readers' credibility perception, but country has no effect. We discuss the implications of our findings for user interface design and social media systems

HOW MICROBLOG FOLLOWER NETWORKS AFFECT OPEN SOURCE SOFTWARE PROJECT SUCCESS

Successful open source software (OSS) projects require efficient communication means and a steady supply of voluntary developers. Microblogging, as well as the follower network it generates, is becoming increasingly popular as an emerging Web 2.0 communication technology in many online OSS communities. However, little is known about how microblogging follower networks affect OSS project success. Based on theories drawn from the social network domain, OSS and virtual team research,we hypothesized two follower network mechanisms – preferential attachment and structural holes – which may significantly affect OSS project success, by improving knowledge sharing and attracting more skillful developers. We plan to empirically study a microblog follower network in a large online OSS community, aiming to examine the impacts of the two hypothesized follower network mechanisms on OSS project success. Our potential findings may provide insights for OSS project managers to better manage microblog communications and thereby achieve project success

Roles of Social Media in Disseminating Health Information: An Exploratory Study in China

Social media have largely transformed the way how health information is disseminated. However, the literature is limited in understanding the applications and implications of social media in health information dissemination. In this exploratory research, we interview Chinese social media users with diverse demographics by asking a set of open-ended questions regarding their use of social media in gaining and sharing health information. This research-in-progress paper reports the results of a preliminary analysis of the qualitative data that we were able to collect from 27 respondents by the time of submission. We find social media to be a major or even the only channel of seeking and sharing health information. Despite a number of relative advantages, the uncertainty about credibility is a major concern of many respondents in practicing and sharing the information gained through social media. These findings provide valuable insights for both research and practice

the role of microblogging in knowledge work

Microblogging in the workplace as a functionality of Enterprise Social Networking (ESN) platforms is a relatively new phenomenon of which the use in knowledge work has not yet received much attention from research. In this cross-sectional study, I attempt to shed light on the role of microblogging in knowledge work. I identify microblogging use practices of knowledge workers on ESN platforms, and I identify its role in supporting knowledge work performance. A questionnaire is carried out among a non-representative sample of knowledge workers. The results shed light on the purposes of the microblogging messages that knowledge workers write. It also helps us find out whether microblogging supports them in performing their work. The survey is based on existing theory that supplied me with possible microblog purposes as well as theory on what the actions of knowledge workers are. The results reveal that “knowledge & news sharing”, “crowd sourcing”, “socializing & networking” and “discussion & opinion” are frequent microblog purposes. The study furthermore shows that microblogging benefits knowledge workers’ work. Microblogging seems to be a worthy addition to the existing means of communication in the workplace, and is especially useful to let knowledge, news and social contact reach a further and broader audience than it would in a situation without this social networking service

Information Reliability on the Social Web - Models and Applications in Intelligent User Interfaces

The Social Web is undergoing continued evolution, changing the paradigm of information production, processing and sharing. Information sources have shifted from institutions to individual users, vastly increasing the amount of information available online. To overcome the information overload problem, modern filtering algorithms have enabled people to find relevant information in efficient ways. However, noisy, false and otherwise useless information remains a problem. We believe that the concept of information reliability needs to be considered along with information relevance to adapt filtering algorithms to today's Social Web. This approach helps to improve information search and discovery and can also improve user experience by communicating aspects of information reliability.This thesis first shows the results of a cross-disciplinary study into perceived reliability by reporting on a novel user experiment. This is followed by a discussion of modeling, validating, and communicating information reliability, including its various definitions across disciplines. A selection of important reliability attributes such as source credibility, competence, influence and timeliness are examined through different case studies. Results show that perceived reliability of information can vary greatly across contexts. Finally, recent studies on visual analytics, including algorithm explanations and interactive interfaces are discussed with respect to their impact on the perception of information reliability in a range of application domains

Microcelebrity Practices: A Cross-Platform Study Through a Richness Framework

Social media have introduced a contemporary shift from broadcast to participatory media, which has brought about major changes to the celebrity management model. It is now common for celebrities to bypass traditional mass media and take control over their promotional discourse through the practice of microcelebrity. The theory of microcelebrity explains how people turn their public persona into media content with the goal of gaining and maintaining audiences who are regarded as an aggregated fan base. To accomplish this, the theory suggests that people employ a set of online self-presentation techniques that typically consist of three core practices: identity constructions, fan interactions and promoting visibility beyond the existing fan base. Studies on single platforms (e.g., Twitter), however, show that not all celebrities necessarily engage in all core practices to the same degree. Importantly, celebrities are increasingly using multiple social media platforms simultaneously to expand their audience, while overcoming the limitations of a particular platform. This points to a gap in the literature and calls for a cross-platform study. This dissertation employed a mixed-methods research design to reveal how social media platforms i.e., Twitter and Instagram, helped celebrities grow and maintain their audience. The first phase of the study relied on a richness scoring framework that quantified social media activities using affordance richness, a measure of the ability of a post to deliver the information necessary in affording a celebrity to perform an action by using social media artifacts. The analyses addressed several research questions regarding social media uses by different groups of celebrities and how the audience responded to different microcelebrity strategies. The findings informed the design of the follow-up interviews with audience members. Understanding expectations and behaviors of fans is relevant not only as a means to enhance the practice’s outcome and sustain promotional activity, but also as a contribution to our understandings about contemporary celebrity-fans relationships mediated by social media. Three findings are highlighted. First, I found that celebrities used the two platforms differently, and that different groups of celebrities emphasized different core practices. This finding was well explained by the interviews suggesting that the audiences had different expectations from different groups of celebrities. Second, microcelebrity strategies played an important role in an audience’s engagement decisions. The finding was supported by the interviews indicating that audience preferences were based on some core practices. Lastly, while their strategies had no effect on follow and unfollow decisions, the consistency of the practices had significant effects on the decisions. This study makes contributions to the theory of Microcelebrity and offers practical contributions by providing broad insights from both practitioners’ and audiences’ perspectives. This is essential given that microcelebrity is a learned practice rather than an inborn trait
