The Quality of Online and Offline Relationships: The Role of Multiplexity and Duration of Social Relationships

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.

Critics have argued that information and communication technologies (ICTs) disconnect people from their social networks and reduce public participation. Research in support of this perspective has been biased by two assumptions. The first is a tendency to privilege the Internet as a social system removed from the other ways people communicate. The second is a tendency to favor broadly supportive strong social ties. Survey and ethnographic observations from Netville, a 2-year community networking experiment, suggest that weak, not strong ties experience growth as a result of ICTs. By examining a unique and underexplored stage in the life cycle of a community networking project, the end of a networking trial, this article demonstrates how ICTs facilitate community participation and collective action (a) by creating large, dense networks of relatively weak social ties and (b) through the use of ICTs as an organizing tool.

共识驱动的网络舆论与社会舆论互动传播研究

依存于网络社会的网络舆论和栖身于现实社会的社会舆论长期分离对立,严重影响舆论传播。如何促使两者由对立转化为协调一致,成为亟待解决的问题。共识是舆论的本质特征,实现网络舆论和社会舆论的协调一致可以从共识形成入手。以舆论传播的共识形成过程为立足点,分析舆论系统的微观主体和宏观表现;进一步地,基于计算实验方法,利用NetLogo平台模拟分析缺乏互动、存在共鸣、存在溢散等不同条件下的舆论传播情况。实验结果表明,网络舆论与社会舆论互动所引起的共鸣效果、溢散效果能够推动舆论传播的共识形成。

Coping with Illness Online: The Case of Patients'Online Communities

This article identifies and analyzes characteristics of patients' online communities (POC) in Sweden. Using a qualitative approach, it presents a fine-grained picture of the communities covering both the structural and cultural factors. Acknowledging the debate about quality of health information online and the potential risks of e-health, the article argues that a deeper understanding of the dynamics of POC, which offer unique aides for the coping process of chronically ill patients, can contribute to the design of the emergent forms of Internet-based health care resources.

关系强度、社会资本对知识获取绩效影响研究--基于社会结构与行动模型

关系强度与社会资本均影响知识获取绩效,已有研究尚未探明两者间联系机理及其对知识获取绩效的影响。本文基于社会结构与行动模型,将社会资本细分为集体与个体两层面;信任、规范与网络异质资源三构件,构建“关系强度—社会资本—知识获取绩效”理论模型,结合233家企业问卷调查与结构方程模型进行实证检验。结果表明：强关联显著提升知识获取绩效;集体社会资本即信任与规范起部分中介作用,个体社会资本即网络异质资源则无中介作用;强关联正向影响网络异质资源,网络异质资源负向影响知识获取绩效但并不显著。明确了关系强度、社会资本对知识获取绩效的影响机理、路径与效果,为企业知识管理提供了关系组建和资本动用的策略参考。

What Tahrir Square Has Done for Social Media: A 2012 Snapshot in the Struggle for Political Power in Egypt

While the debate rages on the role of social media technologies in the initial days of the Egyptian revolution of 2011, a more relevant research question today is the role of social media within an increasingly contested and turbulent political sphere. This article identifies three key modes by which social media is being exploited to impact political power, and uncovers the salience of each of these through 2 years of multisited ethnographies and interviews. First, I argue that political actors across the political spectrum, from liberals to Muslim Brotherhood (Ikhwan), are using technologies to build wider ranging, heterogeneous, and diverse networks of supporters, expanding their base from a more historically homogeneous core support group. Second, I argue that actors are working to build bridges between older and newer media platforms, recognizing that each platform is increasingly being shaped by the other. Finally, I describe some of the ways that technology is being used by activists to subvert their competition, promoting campaigns of misinformation and hacking at the expense of others.     

Online news comments: Social network and emergent public

Abstract

The research on online news comments has been dominated by a normative approach and has centered on media engagement. Normativity and media dominance have also featured big in the theoretical discussions on the public sphere. This article presents a case study of online news comments, combining a novel methodological testing of social network hypotheses to examine user–user interactions in online comments with a conceptual discussion of the potential connections between social network research and theories of the public. The social network analysis in this study indicated that users (online commentators) do not constitute highly dense networks, although their relations can be studied as social networks. However, this analysis can only explore limited features of this online phenomenon and requires complementary methods. From a conceptual perspective, this article confirms the role of shared issue for a potential public and also emphasizes the importance of context, actors, and meanings for understanding the public.     

Instant Messaging on Campus: Use and Integration in University Students' Everyday Communication

This article reviews the body of research on the use and role of instant messaging (IM) in campus life, and how IM is a key part of university students' communication. IM is a synchronous form of communication, and its speed, availability information, and support for multiple conversations have made it appealing for young people. With university students, in particular, showing a heavy reliance on IM, researchers have shown great interest in how university students use IM and how it is integrated in their social and academic life. While studies are emerging in various disciplines, no attempt has been made to integrate the disparate findings and approaches. This article synthesizes key findings, provides a map of the literature, and discusses conceptual problems inherent in the study of IM and other information and communication technologies (ICTs) that will help researchers identify key areas of study and opportunities for future investigation.
