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

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

When public health emergencies occur, a large amount of low-credibility information is widely disseminated by social bots, and public sentiment is easily manipulated by social bots, which may pose a potential threat to the public opinion ecology of social media. Therefore, exploring how social bots affect the mechanism of information diffusion in social networks is a key strategy for network governance. This study combines machine learning methods and causal regression methods to explore how social bots influence information diffusion in social networks with theoretical support. Specifically, combining stakeholder perspective and emotional contagion theory, we proposed several questions and hypotheses to investigate the influence of social bots. Then, the study obtained 144,314 pieces of public opinion data related to COVID-19 in J city from March 1, 2022, to April 18, 2022, on Weibo, and selected 185,782 pieces of data related to the outbreak of COVID-19 in X city from December 9, 2021, to January 10, 2022, as supplement and verification. A comparative analysis of different data sets revealed the following findings. Firstly, through the STM topic model, it is found that some topics posted by social bots are significantly different from those posted by humans, and social bots play an important role in certain topics. Secondly, based on regression analysis, the study found that social bots tend to transmit information with negative sentiments more than positive sentiments. Thirdly, the study verifies the specific distribution of social bots in sentimental transmission through network analysis and finds that social bots are weaker than human users in the ability to spread negative sentiments. Finally, the Granger causality test is used to confirm that the sentiments of humans and bots can predict each other in time series. The results provide practical suggestions for emergency management under sudden public opinion and provide a useful reference for the identification and analysis of social bots, which is conducive to the maintenance of network security and the stability of social order.  相似文献

As social distancing and lockdown orders grew more pervasive, individuals increasingly turned to social media for support, entertainment, and connection to others. We posit that global health emergencies - specifically, the COVID-19 pandemic - change how and what individuals self-disclose on social media. We argue that IS research needs to consider how privacy (self-focused) and social (other-focused) calculus have moved some issues outside in (caused by a shift in what is considered socially appropriate) and others inside out (caused by a shift in what information should be shared for the public good). We identify a series of directions for future research that hold potential for furthering our understanding of online self-disclosure and its factors during health emergencies.  相似文献

Social informatics research offers insights into the relationship between information technologies and social contexts. However, the material roles of information technologies, and their interplay with the agentic work of social actors, have not been addressed. Drawing on a field study of 37 mobile knowledge workers, we examine the dual material roles (enabling and constraining) played by information technologies in their work practices. We also investigate how these workers exert agency by fashioning multiple information technologies into a functioning digital assemblage. Although information technologies provide consequential affordances that enable mobilization of work across spaces and times, they simultaneously present design-driven, local, organizational, and temporal technological constraints that require mobile knowledge workers to engage in “configuration work” to make information technologies function effectively. Building on a sociomaterial perspective, we further discuss the interplay of information technologies and work practices enacted by mobile knowledge workers, in which both human and technological agency are materialized.  相似文献

In the United Kingdom, information and communication technologies are being used to e-enable multiagency community services for children. Public policy advocates that practitioners as well as users should be involved in the shaping of services including the information systems used in their delivery. This article discusses how a group of social and computer scientists developed the social formation methodology to facilitate nonexpert community participation in the design of e-enabled community care services. The longitudinal study adapts qualitative methods to understand community welfare and to foster participation in the design of communication systems. By exploring the perspectives of welfare practitioners and families, the importance of situated and mediated conversations in community care is identified. The facilitative conversation approach of the study then brings these community perspectives, as well as ICT perspectives, into design processes of e-enabled services.  相似文献

Instead of merely subscribing to an unspecific inseparability in the co-constitution or mangle of information technologies and human-actors, there is a need for conceptual tools to describe and explicate the mechanics of how the enmeshment of technologies and human-beings is occurring in information contexts: how information technologies are both setting standards of the social conduct of information practices, and how people are using information technologies to regulate the social process. Building on an empirical study of human-technology relations in the context of archaeological information work, this article discusses how the imaginary of putting Stengers to work can make a contribution to such an end. Stengers describes an ideal system of human-actors and technology working seamlessly —World-as-Clock—that is unattainable but can serve as a benchmark and a lens for understanding frictions and discrepancies in the cohesion of the two.  相似文献

Mobile Phones and the Cultural Ecology of Fishing in Kerala,India   总被引:1,自引:0,他引:1  
Studies that go beyond the ICT4D (Information and Communication Technologies for Development) framework emphasize the social and cultural dimensions of mobile phones. Nevertheless, the cultural dimension, in literature pertaining to both urban and rural use patterns, typically takes an individualistic orientation. The possibility of actualizing the collectivistic logic in a community's appropriation of new technologies is mostly overlooked. The present article explores how the fishers community in Kerala, India, use mobile phones in culturally enhancing and ecologically oriented ways that improve their working and living conditions. In the case of Kerala fishers, the impulse toward cooperation has long been ingrained in their culture, as often happens among marginalized groups. The availability of mobile technologies has allowed for the amplification of this impulse and enabled new modes of cooperation, especially in sharing of information on promising fishing spots and safety and rescue at sea.  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

Unparalleled in human experience, the Internet, or simply the Net, is the code word for the technosocial accident that gives large numbers of people the means by which they can speak for themselves in public. This is an ironical reversal of the historical social patterning of asymmetrical, centralizing communicating technologies that have molded all of the social relations of modern society. The problematic for this distributed communication capability will be manifest in struggles around the legitimacy of self-expression, assembly, and privacy, in all of their forms. However, unlike the mass mediated discourse where, as the 'audience' object, we observed these externalized struggles by a narrow other, encounters with distributed media are palpable and subjective, and will be increasingly played out on the common terrain of local community. In initiating unconditional public access to the Net, community networks, or FreeNets, began the long process of blurring the distinction between the public and private terrain, of undoing that dichotomy that mass media technologies in this century have systematically rebuilt and fortified. Nudging along the process of democratic self-representation is the central issue for the Net, and the epochal project for community networks.  相似文献

Enterprises in both the public and private sector undertake knowledge management (KM) initiatives through which they hope to engender a new, more adaptive and flexible culture of learning and innovation in their organisations. Creative activities involving social learning and innovation are, however, more common in less formal entities such as communities of practice at work and community service organisations in civil society. This paper presents the results and implications of collaborative research into the understanding, development and evaluation of socio-technical systems (STS) designed to mobilise collective knowledge in diverse community settings. The research concerns information and communication technologies (ICT)-mediated activities of communities in the broader civil society and also those in formal organisations. The paper describes and critically evaluates a set of three STS that have the potential to support the collective knowledge of innovative groups, teams and networks, which can all be considered forms of community. The findings could be of strategic value to business, government and community service organisations initiating KM programmes aimed at using collective learning to support innovation.  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

Social informatics is the body of research that examines the design, uses, and consequences of information and communication technologies in ways that take into account their interaction with institutional and cultural contexts. This article serves as a brief introduction to social informatics. Examples such as computer networks, scientific communication via electronic journals, and public access to the Internet are used to illustrate key ideas from social informatics research. Some of the key themes include the importance of social contexts and work processes, sociotechnical networks, public access to information, and social infrastructure for computing support. The article draws upon 25 years of systematic analytical and critical research about information technology and social change.  相似文献
