This study summarizes prior reviews of new media and Internet research, and the growth of the term Internet in academic publications and online newsgroups. It then uses semantic network analysis to summarize the interests and concepts of an interdisciplinary group of Internet researchers, as represented by session titles and paper titles and abstracts from the 2003 and 2004 Association of Internet Researchers conferences. In both years, the most frequent words appearing in the paper abstracts included Internet, online, community, social, technology, and research. The 2003 papers emphasized topics such as the social analysis/research of online/Internet communication, community, and information, with particular coverage of access, individuals, groups, digital media, culture; role and process in e-organizations; and world development. The 2004 papers emphasized topics such as access; news and social issues; the role of individuals in communities; user-based studies; usage data; and blogs, women, and search policy, among others.  相似文献

New media studies are now benefiting from a burgeoning of empirical studies and theoretical analyses from diverse academic disciplines seeking to locate new media, especially the Internet, within longstanding traditions of social science research. By reviewing and reflecting upon findings from UK Children Go Online, a multimethod research project examining the role of the Internet in children's and young people's everyday lives, the present article takes the opportunity to draw out some general conclusions, and associated puzzles, to guide future research. These contribute toward an emerging framework for understanding questions regarding new media access, use, and consequences within the social, cultural, and political parameters of young people's lives. A range of research findings are discussed that illuminate the shifting balance of opportunities and risks posed by the Internet for children, youth, and the family.  相似文献

Might online social relations play a role in the rise of political solidarities sufficient to support a democratic postnationalist project? As things currently stand, it does not appear that the Internet supports either the commitment or cohesiveness needed to underpin a demanding new mode of social and political relations. Looking at factors such as conceptions of community and social interaction, systems of meaning, political engagement, and social inclusivity can help us assess the question. The exercise suggests that while the Internet may be a factor in change, it may not yield the kind of change many are anticipating. This finding raises doubts concerning the postnationalist hope that new social and political bonds will help ground transnational projects such as the European Union.  相似文献

Identifying widely disseminated papers (WDPs) on social media can help to understand dissemination mechanisms of scientific papers from academia to social media and assist in the formulation of public and science policy. This study applies machine learning methods to explore the possibility of identifying WDPs and to investigate the influence mechanisms of literature-related and social media-related features. A pre-task was first conducted to investigate whether the visibility of scientific papers on social media can be predicted, and the role of various features was analyzed. Then, we defined two predictive tasks for identifying WDPs before and after they are visible on social media. The performance of eight state-of-the-art algorithms was compared in three experiments against the dataset of the oncology field, and the contribution of literature-related and social media-related features in the tasks was explained based on the Shapley additional explanations (SHAP) value. The results show that XGBoost performs better than other algorithms, especially with an F1 score of 0.988 and AUC of 0.998 in the trend prediction task. Nearly all of the literature-related features have great effects on identifying long-term disseminated papers, and most social media-related features play more significant roles in identifying broadly mentioned papers. Moreover, journal features contribute more to identifying papers of social media visibility, while paper features, especially research topics, have a greater influence on identifying WDPs. The number and proportion of academic-related Twitter users have great impacts on the scale and duration of papers’ dissemination. The number and duration of first-generation tweets play critical roles in identifying broadly mentioned and long-term disseminated papers, respectively. This study provides profound insights into the influencing factors in the dissemination of papers from the scientific community to and across social media, and helps to understand the difference in knowledge propagation between academia and the public.  相似文献

Communities with high levels of social capital are likely to have a higher quality of life than communities with low social capital. This is due to the greater ability of such communities to organize and mobilize effectively for collective action because they have high levels of social trust, dense social networks, and well-established norms of mutuality (the major features of social capital). Communities with “bridging” social capital (weak ties across groups) as well as “bonding” social capital (strong ties within groups) are the most effective in organizing for collective action. People who belong to multiple groups act as bridging ties. When people with bridging ties use communication media, such as the Internet, they enhance their capability to educate community members and to organize, as needed, for collective action. This article summarizes evidence from stratified household survey data in Blacksburg, VA, showing that people with weak (bridging) ties across groups have higher levels of community involvement, civic interest, and collective efficacy than people without bridging ties among groups. Moreover, heavy Internet users with bridging ties have higher social engagement, use the Internet for social purposes, and have been attending more local meetings and events since going online than heavy Internet users with no bridging ties. These findings may suggest that the Internet—in the hands of bridging individuals–is a tool for enhancing social relations and information exchange, and for increasing face-to-face interaction, all of which help to build both bonding and bridging social capital in communities.  相似文献

Making Space for Religion in Internet Studies   总被引:1,自引:0,他引:1  
This article seeks to address how religion fits into the larger domain of Internet studies and why studies of religion within computer-mediated communication (CMC) need to be given more attention. An argument is made for the need to take religion online more seriously, not just because it is an interesting phenomenon or a popular use of the Internet, but also because religion continues to be an important part of contemporary life for many people. A summary of the growth and development of religion online is presented along with an overview of how religion has been approached and studied on the Internet. This review shows what CMC studies of religion might offer in approaching research questions related to authority, identity construction, and community online. It calls for recognition of the contribution, and possibilities that underrepresented areas within interdisciplinary research, like religion, might offer Internet studies as a whole.  相似文献

The emergence of social media has fundamentally changed the way of scholarly communication and allows for scientific research to be shared at an unprecedented speed and scale. While many studies have discussed what papers attract most online attention, how they prevail online is unclear. In this paper, we explore the diffusion patterns of ~170,000 papers with different journal tiers from 2012 to 2019 based on over 3 million Twitter mentions. We first categorize journals by the elite (the top of Q1) and non-elite (Q2~Q4) according to their journal impact factor quartiles, then use network analysis and time series analysis to characterize papers’ dynamic diffusion process, and finally discuss papers’ engaged users and disciplinary contexts. Results show that though elite journal papers spread significantly faster and more broadly than non-elite, some non-elite journal papers reached a sizable audience. For non-elite journal papers, a decent size of social media reach can be achieved through the aid of highly influential users or multiple waves of small spread that span a long period. As a result, popular non-elite journal papers tend to be more viral than the elite, focusing discussions around topics close to daily life. This study provides a new perspective to characterize the diffusion process of scientific papers and helps to further enhance the understanding of such a process.  相似文献

This article provides a critical comparative analysis of mobile versus personal computer (PC)-based forms of Internet access. Drawing from an interdisciplinary body of literature, it illustrates a wide range of ways in which mobile Internet access offers lower levels of functionality and content availability; operates on less open and flexible platforms; and contributes to diminished levels of user engagement, content creation, and information seeking. At a time when a growing proportion of the online population is “mobile only,” these disparities have created what is termed here a mobile Internet underclass. The implications of this argument for digital divide policymaking and, more broadly, for the evolutionary trajectory of the Internet and the dynamics of Internet usage are discussed.  相似文献

This paper contributes to the understanding of online strategies in the context of museums as examples of cultural organisations, an underrepresented sector in the information management literature. It presents a theoretical framework for understanding the online strategies of museums’ use of Web and social media, their sources of online value (efficiency, novelty, lock-in, complementarities) and some measurements of Internet performance, such as the Alexa Internet ranking and the number of followers of museums in social media. This type of analysis has not been conducted before and the findings will help museum curators and managers of other cultural institutions to appreciate the impact of these technologies and to make better informed decisions regarding online strategies and resource allocation. In addition, the results of this research are applicable to similar organisations, such as archives and cultural exhibitions, as well as to other service organisations related to information, education and entertainment activities.  相似文献

Recent studies have shown that adolescents use the Internet not only to maintain social relationships with distant relatives and friends but also to create new relationships online; some of these friendships become integrated into their social circle. Research has focused mainly on the effect of the Internet on existing relationships or the nature of online-only ties, so studies comparing the quality of online and face-to-face relationships are missing. The goal of this study is to bridge this gap. In keeping with previous studies on social association, we argue that the quality of social relationships is dependent on duration and diversity of topics and activities carried together. Time is important, as it facilitates the development of a collective shared history and identity. Intimacy develops through the participation in shared activities and discussion of diverse issues of personal concern. Using a representative sample of the adolescent population in Israel, we find that closeness to a friend is a function of social similarity, content and activity multiplexity, and duration of the relationships. Friendships originated in the Internet are perceived as less close and supportive because they are relatively new and online friends are involved in less joint activities and less topics of discussion. The implications of the findings are discussed.  相似文献
