How social media can enable opportunities for collaboration between citizens and governments is an evolving issue in theory and practice. This paper examines the dynamic aspects of collaboration in the context of the 2011 riots in England. In August 2011, parts of London and other cities in England suffered from extensive disorder and even loss of human lives. Based on a dataset of 1746 posts by 81 local government Twitter accounts during or shortly after the riots, we explore how local authorities attempted to reduce the effects of the riots and support community recovery. Using Twitter's conversational and rapid update features, they produced a variety of informational and actionable messages with clear calls for offline or online action. In some cases, collective against the riots evolved in a mutual way: not only citizens were mobilized by local authorities, but also local authorities actively promoted actions initiated by citizens. 相似文献

Facebook is the most popular social media site visited by university students on a daily basis. Consequently, Facebook is the logical place to start with for integrating social media technologies into education. This study explores how a faculty‐administered Facebook Page can be used to supplement anatomy education beyond the traditional classroom. Observations were made on students' perceptions and effectiveness of using the Page, potential benefits and challenges of such use, and which Insights metrics best reflect user's engagement. The Human Anatomy Education Page was launched on Facebook and incorporated into anatomy resources for 157 medical students during two academic years. Students' use of Facebook and their perceptions of the Page were surveyed. Facebook's “Insights” tool was also used to evaluate Page performance during a period of 600 days. The majority of in‐class students had a Facebook account which they adopted in education. Most students perceived Human Anatomy Education Page as effective in contributing to learning and favored “self‐assessment” posts. The majority of students agreed that Facebook could be a suitable learning environment. The “Insights” tool revealed globally distributed fans with considerable Page interactions. The use of a faculty‐administered Facebook Page provided a venue to enhance classroom teaching without intruding into students' social life. A wider educational use of Facebook should be adopted not only because students are embracing its use, but for its inherent potentials in boosting learning. The “Insights” metrics analyzed in this study might be helpful when establishing and evaluating the performance of education‐oriented Facebook Pages.

Users’ ability to retweet information has made Twitter one of the most prominent social media platforms for disseminating emergency information during disasters. However, few studies have examined how Twitter’s features can support the different communication patterns that occur during different phases of disaster events. Based on the literature of disaster communication and Media Synchronicity Theory, we identify distinct disaster phases and the two communication types—crisis communication and risk communication—that occur during those phases. We investigate how Twitter’s representational features, including words, URLs, hashtags, and hashtag importance, influence the average retweet time—that is, the average time it takes for retweet to occur—as well as how such effects differ depending on the type of disaster communication. Our analysis of tweets from the 2013 Colorado floods found that adding more URLs to tweets increases the average retweet time more in risk-related tweets than it does in crisis-related tweets. Further, including key disaster-related hashtags in tweets contributed to faster retweets in crisis-related tweets than in risk-related tweets. Our findings suggest that the influence of Twitter’s media capabilities on rapid tweet propagation during disasters may differ based on the communication processes. 相似文献

Ask an anatomist: Identifying global trends,topics and themes of academic anatomists using twitter 
下载免费PDF全文
下载免费PDF全文 Social media (SoMe) is increasingly used in higher education (HE) to access knowledge and enable global communication. The SoMe platform Twitter® is particularly beneficial in these contexts because it is readily accessible, easily searchable (via hashtags) and global. Given these advantages, the twitter platform @AskAnatomist was created to foster a global weekly tweet chat, where students and academics can ask and address anatomy‐related questions. The aim of this study was to identify themes arising in the early stages of the @AskAnatomy Twitter community to gain insights into current needs/key areas for academic anatomists, students, and other followers. A qualitative analysis of tweets including the hashtag #AnatQ, (the associated @AskAnatomist hashtag), was undertaken to achieve this aim. Thematic analysis revealed three core themes arising in the formative stages of the @AskAnatomist Twitter site: (1) anatomical education modalities, (2) specific anatomy content, and (3) research motivations. These themes reveal controversies within the field of anatomical sciences, areas for potential education resource improvement and research, as well as the humor of anatomists. Though the original intent of the @AskAnatomist site was to engage the general public in anatomy content and knowledge, tweet analysis suggests that academic anatomists were the primary active “tweeters”. Interestingly, this analysis reveals that the @AskAnatomist site progressed into a web‐based community of practice (CoP), suggesting an additional benefit of SoMe communities in the field of anatomy.

Social networks are becoming a key communication tool for organizations, but also for top managers like CEOs. Among the different available platforms, Twitter is one of the greatest and it is considered one of the most suitable to share information and engage in dialogue with stakeholders. In this way, this paper analyzes the presence of CEOs on the most active social network sites, and assess the activity and interaction of these top managers on Twitter. CEOs from Global and Latin American companies were selected, to compare their performance. The results of the study show that the presence of CEOs in social networks is very low, and the majority of those that are present on them are not adequately using their Twitter accounts. Although the general presence and performance on are low, LatAm CEOs have a better presence on social networks and they are more active on Twitter, but Global CEOs have better interaction results on their accounts. So, this area of strategic communication should be improved by communication practitioners, since the CEO communication is nowadays a key communication issue for any organization. 相似文献

Mathematics teachers are using Twitter as a backchannel at conferences. Understanding whether teachers are using Twitter differently at traditional conferences like the National Council of Teachers of Mathematics (NCTM) Annual as compared to new conference models like TwitterMathCamp (TMC) is important. Tweets surrounding the 2015 NCTM Annual and TMC2015 were collected and analyzed to determine the differences in tweeting behavior of the mathematics teachers. Our results showed teachers use Twitter in common ways, despite the attention placed on social media at new conferences. 相似文献

ABSTRACT News organizations increasingly focus their efforts to boost traffic on their websites to grow their share of online advertising. We investigated the relationship between news websites’ traffic ranking and their social media tools of Facebook, Twitter, YouTube and Google Plus. For a year we monitored the followers of all Greek regional newspapers in relation to the traffic on their websites. We continued monitoring for a second year to validate the robustness of the findings and we hereby present results for 86 weeks. Statistical analysis leads to the conclusion that the number of social media subscribers can predict the competitive position of a newspaper in the market based on its website traffic. The effect lasts for a limited period of time, one to three weeks, depending on the specific medium. Importantly, results indicate the potential of developing a prediction model of the website’s traffic, based on the social media metrics of the organization, as a useful tool to increase traffic and revenues from online advertising. 相似文献

ABSTRACT The aim of this paper is to probe into the social media use by Chinese climate journalists through the examination of their professional practices on social media. Taking COP21 as a case, the study conducted a survey from Chinese COP21 journalists and analyzed WeChat and Weibo posts from Chinese journalists and tweets from their UK and US colleagues. The results show the prevalent use of WeChat among Chinese journalists and the personalization of the social media content accordingly. Compared to their Western counterparts, the use of social media for professional purposes by Chinese COP21 journalists was relatively limited. Nevertheless, several patterns of using social media were identified. Specifically, Chinese journalists tended to more frequently express personal opinions, discuss work experience and favor conventional news sources of authority than UK and US journalists. The results also suggest that climate change in Chinese media discourse will remain more a policy-related issue instead of an environmental or scientific issue, with Chinese government playing a central role. 相似文献
