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. 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

草地租赁是中国牧区草地流转的主要途径。探讨影响牧户草地租赁行为的因素,健全和完善草地租赁市场,对于维持草原生态平衡、提高牧户收入、促进牧区繁荣和稳定,具有重要意义。本文基于青海省门源县4个村的实地调研数据,构建牧户社会网络,以强关系和弱关系两类社会网络结构特征指标,代替传统的个体社会资本指标,利用Heckman两阶段模型,实证检验社会网络对牧户草地租入倾向和强度的影响。结果表明：①建立在血缘、地缘、亲缘等关系基础上,具有潜在规则约束力的强关系,显著提高了牧户草地租入倾向和租入强度;②反映牧户在村集体内的权利、地位,高效率传递非冗余、异质性信息的弱关系,有助于打破草地租赁市场的“隐形壁垒”和“准入限制”,也能够显著提高牧户草地租入倾向和租入强度。政府应积极培育牧民专业合作社与畜牧业生产企业,定期举办各类民族传统文化活动,营造互信互助互惠的牧区文化环境,充分发挥社会网络在发展草地租赁市场和实现牧区乡村振兴中的作用。 相似文献

Over one billion people are currently using social media such as social websites (Facebook Newsroom, 2015); consequently, numerous academic scholars have developed interest in studying the use of social media and social networks. However, few studies have focused on examining the core factors of social networks. In this study, we collected studies on social-network-related topics that were published between January 1996 and December 2014, assembling a total of 2565 articles and 81,316 citations. Co-citation analysis and cluster analysis were applied to verify seven main factors regarding social networks: (a) the measure of complex social networks; (b) community structure; (c) strong and weak ties; (d) the evolution of social networks; (e) network structure and relationship; (f) value concept and measurement strategies; and (g) social capital. Finally, the results of this study were further discussed to elucidate the core topics relevant to social networks. 相似文献

The technology acceptance model (TAM) has been widely used to study user acceptance of new computer technologies. However, it does not incorporate social structure and influence as a significant factor. In this study, we ask the following questions: (i) What are the limitations of the existing TAM for studying virtual community? (ii) What is effect of social networks on user acceptance of technology for virtual community? and (iii) How can the influence of different types of social ties serve as a basis for exploring the user acceptance of technology in a virtual community? Here, we explore the possibility for extending TAM to incorporate the influence of the different types of social ties as a new theoretical construct. Preliminary analysis of data from a virtual community results show that weak and strong ties influence technology acceptance. The findings enable HCI researchers to account for influence of social ties in future investigations using TAM. 相似文献

The strength of strong ties in the creation of innovation 总被引：4，自引：0，他引：4
Katja Rost 《Research Policy》2011,40(4):588-604
There is an ongoing debate in innovation research as to which type of social capital is more conducive to innovation: structural holes as proposed by Burt or network closure as proposed by Coleman. Although Coleman focused on the quality of relationships, Burt argued that the structural configuration of relationships was more important. I argue that, instead of being alternative substitutes, Burt's social capital theory complements Coleman's theory. More precisely, I demonstrate that, in the presence of strong ties, weak network architectures (structural holes or a peripheral network position) leverage the strength of strong ties in the creation of innovation. This implies that weak network architectures have no value without strong ties, whereas strong ties have some value without weak network architectures but are leveraged by this type of structure. The findings indicate that innovation research tends to overestimate the impact of weak network architectures in the creation of innovation. By pointing to the necessity of strong ties, the results may be of particular interest for research on open innovation. They suggest that open innovation will not work if closed innovation principles are pushed back. 相似文献

This article examines how we use mobile telephony to maintain our physically and socially closest social circle. The analysis is based on traffic data gathered from Norway using approximately 24 million calls and texts made by private individuals. Previous research has shown that our temporal and spatial movement is highly predictable and that the majority of calls and text messages are sent to only four to six different persons. This article extends this research by examining both tie strength and the distance between the interlocutors in urban and rural settings. The findings show that even as information and communication technologies (ICTs) potentially put the world at our fingertips, the mobile phone is an instrument of a more limited geographical and social sphere. Approximately two-thirds of our calls/texts go to strong ties that are within a 25-km radius. 相似文献

Strong, Weak, and Latent Ties and the Impact of New Media 总被引：2，自引：0，他引：2
Caroline Haythornthwaite 《The Information Society》2002,18(5):385-401
This article argues that consideration of the strength of ties between communicators can help reconcile disparate results on the impact of new media on social relations. It is argued from the research literature and studies by the author that where ties are strong, communicators can influence each other to adapt and expand their use of media to support the exchanges important to their tie, but where ties are weak, communicators are dependent on common, organizationally established means of communication and protocols established by others. Due to this differential use of media, a new medium that adds means and opportunities for previously unconnected others to communicate will have positive effects on weak ties and weak-tie networks, in particular by laying an infrastructure of latent ties (ones that exist technically but have not yet been activated), and providing an opportunity for weak ties to develop and strengthen. A new medium may also have positive effects on strongly tied pairs where it adds another means of communicating and supports the communication needs and tasks of the pair. However, where a new medium replaces a former, common means of communication, the dependence of weak ties on a common medium makes weak-tie networks highly susceptible to dissolution. In contrast, strong-tie networks, with their connections via multiple relations and multiple media, can be expected to be more robust under conditions of change. 相似文献

This study examined the development of individual social capital in a distributed learning community. Feld's theory of focused choice predicts that the formation of network ties is constrained by contextual factors that function as foci of activities. In our research, we examined how group assignment and location could function as such foci to influence the development of individual social capital in a distributed learning community. Given that networks with different content flows may possess different properties, we examined two different types of networks—task-related instrumental networks and non-task-related expressive networks. A longitudinal research design was used to evaluate the evolution of networks over time. Hypotheses were tested using a sample of 32 students enrolled in a distributed learning class. The results show strong support for Feld's theory. While serving as foci of activities to organize social interactions, both group assignment and geographic separation can also function to fragment a learning community. 相似文献

Evidence demonstrates that the digital divide is deepening despite strategies mobilized worldwide to reduce it. In disadvantaged communities, beyond training and infrastructural issues, there often lies a range of cultural and historically formed relationships that affect people's adoption of ICTs. This article presents an analysis of local resident's engagement with their council's pilot project to develop a computer facility in their community center. We ask, to what extent can people in poor urban communities, once trained, be expected to volunteer to work on furthering community education and development in ICTs in their local area? Findings indicate four patterns of individual engagement with the computer project: reflexive, utilitarian, distributive, and nonparticipatory. It is argued that local people engaged with the intervention in historically patterned and locally distinctive ways that served immediate personal and pragmatic ends. They did not adopt the long-term strategic goals of the council or university. 相似文献

In emergencies, information sharing among and between officials, volunteers, and citizens is essential for effective recovery and management. Recently, volunteers and others have been using community technology centers, community wireless networks, and end-user social technologies such as blogs and Wikis to prepare for emergencies and communicate and coordinate response when they happen. This article argues that there is a need for a research agenda that combines our knowledge of community informatics with the principles of disaster management to understand how social networks form and mobilize in disasters and how information and communication technologies should be designed and deployed to engage, inform, and mobilize those volunteer and citizen networks. 相似文献
