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.

Digital stigma coping strategies: A meta-analytic review of the association between health-related stigma dimensions and social support messages shared online

Abstract

Although stigma is widely accepted to be a multidimensional construct, the implications of its dimensions for social support warrant greater consideration. We conducted a meta-analysis of 31 content analyses to investigate the association between specific dimensions of stigma and the types of social support messages shared in health-related contexts online. Among health conditions where character stigma was greater, information, network, and tangible support were more prevalent. Physical stigma was associated with a higher prevalence of esteem support. Information, emotional, network, and tangible support were more prevalent among health conditions where concealable stigma was greater. Among health conditions where visible stigma was greater, information, and esteem support were more prevalent. Our study contributes to stigma and social support research by providing evidence that health-related stigma has multiple dimensions each with distinct implications for social support. More broadly, this project offers a framework that can be used to examine the ways in which social meanings of health conditions may be translated into digital behavior.     

自我构建理念对网络分享推荐意愿的影响研究

研究自我构建方式(相依自我和独立自我)对网络分享推荐意愿的影响,重点考察社会风险的中介作用和平台关系强度(关系紧密和关系疏远)的调节作用.研究结果表明:自我构建方式对在线分享推荐意愿有显著影响,与独立自我的分享者相比,相依自我的分享者在线分享推荐意愿低.不同自我构建方式的分享者通过感知社会风险的差异影响在线分享推荐意愿.此外,自我构建方式与平台关系强度之间存在调节效应,即在关系紧密的平台上,不同自我构建方式的分享者的分享推荐意愿差异显著.而在关系疏远的平台上,不同自我构建方式的分享者的分享推荐意愿无显著差异.     

The Internet, Spatial Data Globalization, and Data Use: The Case of Tibet

One of the fastest growing forms of downloadable Internet-based data involves digital map layers that contain spatial features suitable for analysis with a geographic information system (GIS). The availability of networked spatial data has fostered tremendous growth in the importance and use of location-based services, and it is now commonplace to find a wide variety of map-based applications and data sets on the Internet for unrestricted download. Despite the rapid growth in spatial data resources, there has been scant attention paid to their currentness, lineage, locational accuracy, completeness, and overall usefulness. This article discusses the quality of Internet spatial data by taking an extreme case to evaluate both the availability and the usefulness of spatial data posted on publicly accessible Web sites. The case study examined is Tibet, which is selected purposively because it lies at or beyond the fringes of the network society. The issue examined concerns the rehabilitation potential of locatable Buddhist monasteries. In undertaking this assessment, the efficacy of the current Internet as a source of useful spatial data is brought into question.     

Conceptualizing and Measuring the Social Uses of the Internet: The Case of Personal Web Sites

The researchers working on information society measures have recently started to consider how people use the Internet not only as a tool but also as a platform for social relations. As the ultimate objective of information society measures is to provide reliable guidelines for social policy, finding criteria for separating “positive” uses of Internet from “negative” ones is an important task. This article employs the concepts of communicative and strategic action as defined by Habermas for that purpose. A general conceptual typology of three communicative and three strategic social uses of Internet is offered, which can be applied to measure uses of any of the Internet's interactive services. A specific empirical application to social uses of personal web sites demonstrates that the deduced measurement instruments achieve satisfying levels of validity and reliability.     

Antecedents of privacy calculus components in virtual health communities

Over the past decade, social media technologies have become effective tools not only for entertainment, but also for online health communications. In virtual health communities (VHCs), the members often share their personal health information (PHI) with other members. These information exchanges provide benefits to both the information providers as well as the recipients. The PHI disclosure, however, may entail privacy concerns. Our study used the privacy calculus model to examine the trade-off between individuals’ expected benefits and privacy concerns when disclosing PHI in social media environments. Our results showed that age, health status, and affective commitment influence the balance between the information disclosure drivers and barriers in the privacy calculus model. More specifically, we found that among members of VHCs, healthier people expect to receive fewer personal benefits of communicating PHI in social media environments. Moreover, individuals who are emotionally attached to online communities expect to both receive and provide more benefits while communicating PHI in those communities. We also observed that individuals who are familiar with but not members of VHCs, especially those who are young and healthy, are more concerned about their PHI privacy in online communities.     

变革的积极应对、工作投入对员工绩效的影响——技能的调节作用

个体行为的改变对组织变革有决定性的影响。应对是个体面对组织变革压力时的一种典型的行为反应,理应成为研究的重点。然而传统的组织变革研究忽视了对个体因素的考察。受心理学影响,消极研究倾向长期成为组织行为学的主流。近年来,组织中的积极主动行为受到广泛关注。从微观视角、个体层面对组织变革情境下个体的积极应对与其绩效的关系及其影响机制进行的实证研究发现,变革压力下个体的积极应对对员工绩效和工作投入均有显著影响;工作投入在积极应对与员工绩效关系中起中介作用;员工的技能可调节积极应对与任务绩效之间的关系。因此,变革的管理者应给予个体足够的重视,注意激发员工的积极情绪和行为,提高其工作投入状态和技能水平。     

The Persistence of Information Structures in Nordic Countries

This article examines to what extent the Nordic countries, which have been characterized as the world's leading information societies, show similar patterns of Internet use. The data consists of the Danish, Swedish, Norwegian, and Finnish sections of the European Social Survey 2002 ( n = 7539) and 2004 ( n = 7211). The similarities and differences in the Internet use are analyzed using sociodemographic and economic information. Temporal changes in the distribution of use between population groups and between countries are also examined. The findings indicate that there are clear disparities in the Internet use patterns, which have not evened out in the early 21st century.     

Cultured Technology: The Internet and Religious Fundamentalism

In this article we identify four principal dimensions of religious fundamentalism as they interact with the Internet: hierarchy, patriarchy, discipline, and seclusion. We also develop the concept of cultured technology, and analyze the ways communities reshape a technology and make it a part of their culture, while at the same time changing their customary ways of life and unwritten laws to adapt to it. Later, we give examples for our theoretical framework through an empirical examination of ultra-Orthodox Jewish communities in Israel. Our empirical study is based on a data set of 686,192 users and 60,346 virtual communities. The results show the complexity of interactions between religious fundamentalism and the Internet, and invite further discussions of cultured technology as a means to understand how the Internet has been culturally constructed, modified, and adapted to the needs of fundamentalist communities and how they in turn have been affected by it.
