This paper aims the Benin Library and Information Science (LIS) professionals’ access to individuals on the social network through the study of the structure and use of the network. Subscribers to the library association’s listserv participated in a web-based survey to identify the colleagues they could easily reach. The analysis uses social network techniques and Pajek, a social network analysis software, and focuses on centralities, prestige and sub-groups to identify the key actors required for effective information sharing within the network.The density of this is very low and suggests that intermediaries are important for the connectedness of subscribers (also referred to as actors); network centralisation is moderate and explains that some actors are central for communication among the subscribers. About 60% of the subscribers fall within one of two groups. In the first group, six subscribers are central to the network, because they are moderators of the listserv, members of the association board, or well-connected to other well-connected actors. The others fall within the isolates or had few connections. 相似文献

The purpose of this paper is to theoretically and empirically explore how public e-procurement policies are translated into practice. The theoretical argument draws on actor network theory (ANT), coupled with Colebatch’s [Colebatch, H. K. (2002). Policy (2nd ed.). Maidenhead, Open University Press.] social construct of policy, to analyze the actors, actions, and circumstances through which understanding of public e-procurement comes to stabilize (or not) into a coherent policy for action. Drawing on three case studies of central government agencies in Italy, Scotland, and Western Australia, we suggest new intellectual perspectives and methodological heuristics that may assist researchers and practitioners analytical efforts in examining sociotechnical change and the implications for policy development and implementation. 相似文献

Previous research shows that researchers’ social network metrics obtained from a collaborative output network (e.g., joint publications or co-authorship network) impact their performance determined by g-index. We use a richer dataset to show that a scholar's performance should be considered with respect to position in multiple networks. Previous research using only the network of researchers’ joint publications shows that a researcher's distinct connections to other researchers, a researcher's number of repeated collaborative outputs, and a researchers’ redundant connections to a group of researchers who are themselves well-connected has a positive impact on the researchers’ performance, while a researcher's tendency to connect with other researchers who are themselves well-connected (i.e., eigenvector centrality) had a negative impact on the researchers’ performance. Our findings are similar except that we find that eigenvector centrality has a positive impact on the performance of scholars. Moreover, our results demonstrate that a researcher's tendency toward dense local neighborhoods and the researchers’ demographic attributes such as gender should also be considered when investigating the impact of the social network metrics on the performance of researchers. 相似文献

I examine the vernacular discourse of the CHICLE listserv, an academic site of inquiry that shifted its focus to operate as a site of opposition following California voters’ passage of Proposition 187, which aimed to restrict state services to undocumented immigrants. I identify the micro-level processes involved in forming a stance of opposition and reveal that a vernacular community's discourse tends to mirror the hegemonic characteristics of the dominant discourses it opposes, a tendency reinforced by homogeneous identity and a need to respond in opposition to dominant discourses. I also examine the role of dissent, or discord, among listserv members. 相似文献

Communication network is a personal or professional set of relationships between individuals or organizations. In other words, it is a pattern of contacts which are created due to the flow of information among the participating actors. The flow of information establishes various types of relationships among the participating entities. These relationships eventually form an overall pattern that could form a gestalt of the total structure within organizational context. In this paper, we analyze the changing communications structure in order to investigate the patterns associated with the final stages of organizational crisis. Organizational crisis has been defined as organizational mortality, organizational death, organizational exit, bankruptcy, decline, retrenchment and failure to characterize various forms of organizational crisis. We draw on theoretical perspectives on organizational crisis proposed by social network analysts and other sociologists to test 5 key propositions on the changes in the network communication structure associated with organizational crisis: (1) a few actors, who are prominent or more active, will become central during the organizational crisis period; (2) reciprocity within the organizational communication network will increase during crisis period; (3) organizational communication network becomes less transitive as organizations experience crisis; (4) number of cliques increases in a communication network as organizations are going through crisis; and (5) communication network becomes increasingly centralized as organizations go through crisis. 相似文献

Political communication researchers have shown that social network site (SNS) use and online network characteristics can impinge on people’s political attitudes and behavior. Nevertheless, individual SNSs have varying site architecture, basic design features, and functionalities, which may influence usage and online network characteristics. This study thus examines whether site architecture matters for understanding the political implications of SNSs. Specifically, this article conceptualizes the distinction between public-oriented and private-oriented SNSs. It contends that the two types of SNSs would have varying impact on political behavior through the kinds of online networks that they tend to sustain. Analysis of a survey of university students in Guangzhou, China (N?=?897), shows that respondents using public-oriented SNSs tended to have a relatively more ‘public’ online network – larger, involving more strangers, and with more connections to public actors. Some of these network characteristics in turn affected political discussion behavior. The analysis thus demonstrates how SNS architecture can indirectly impinge on individual-level political outcomes. 相似文献

First-time freshmen completed communication skills questionnaires at the beginning of a fall semester. Approximately 6 weeks later they completed another questionnaire regarding friendship formation strategies and the perceived availability of resources from their new social network. Results suggest that different profiles of communication skills predicted how much freshmen reported using group involvement, online social networking, disclosure, responsiveness, and invitations as friendship formation strategies. Communication skills and friendship formation strategies were also associated with the perceived availability of social, personal, and instrumental resources. Implications for freshmen's social integration into a new university environment are discussed. 相似文献

ABSTRACT A growing number of institutions are offering courses and degrees via distance education; however, distance education librarianship is a relatively new and often less defined field of librarianship. This paper will present the results of a survey to discover career paths leading to distance education librarianship. Based on a survey of subscribers to the OFFCAMP listserv, it asked questions such as: Is there a “typical” career path? Does previous or continuing work in other library units benefit a distance education librarian? What are the most important qualifications for a distance education librarian? Profiles of the education and experience of distance education librarians were analyzed for commonalities. The study concluded that distance education librarians come to their positions from a variety of experience, not always in libraries, but predominantly from library public service departments. A typical career path for distance education librarians is not evident at this time. 相似文献

Intertextuality and nationalism discourse: a critical discourse analysis of microblog posts in China
Mengjun Guo 《亚洲交流杂志》2013,23(4):328-345
As an important dimension of contentious politics, online political discourse reveals crucial issues related to ideology, power, and identity in times of political struggle. Drawing on Norman Fairclough’s intertextual analysis approach within the paradigm of Critical Discourse Analysis in an online discursive context, this study examines the role of intertextuality in the discursive construction of social movements. It does so by analyzing how different social actors employ discursive tools to construct the pro-democracy Umbrella Movement in their online commentaries. Focusing on discourse, genre, and style, this study demonstrates how online texts draw from different intertextual resources and how they echo the broader nationalist discourse in China. In addition, this paper also uncovers how the circulation and combination of these intertextual resources in an authoritarian context form specific constructions of the Umbrella Movement. 相似文献

Israel’s public diplomacy efforts in the U.S. are aimed at garnering American public support for Israeli foreign policy. This study aims to identify the networks of Israeli public diplomacy toward the United States. Using the theoretical frameworks of networked public diplomacy and strategic narrative, the authors try to understand how network strategy is used and information is circulated to create a strategic narrative. Therefore, the two methods of social network analysis and qualitative content analysis are applied to identify the networks of Israeli public diplomacy in the United States and the content produced by it. The study finds that in Israel’s public diplomacy model, the networking method stands in contrast to its government-oriented strategic narrative. Thus, new forms of communication are applied to conduct old strategies. The research identifies four types of actors who apply new public diplomacy techniques and dissects the strategic narrative they employ to affect the American public in the service of Israeli interests. Despite the effort to apply new forms of public diplomacy, strategic narrative production and dissemination remain highly governmental and closed, which is indicative of the persistence of old forms of public diplomacy. 相似文献

Social network analysis: An approach and technique for the study of information exchange 总被引：3，自引：0，他引：3
Social network analysis is an approach and set of techniques used to study the exchange of resources among actors (i.e., individuals, groups, or organizations). One such resource is information. Regular patterns of information exchange reveal themselves as social networks, with actors as nodes in the network and information exchange relationships as connectors between nodes. Just as roads structure the flow of resources among cities, information exchange relationships structure the flow of information among actors. Social network analysis assesses information opportunities for individuals or groups of individuals in terms of exposure to and control of information. By gaining awareness of existing information exchange routes, information providers can act on information opportunities and make changes to information routes to improve the delivery of information services. 相似文献

The current research explored a new social movement network in the northeastern United States in order to build on past research concerning a Resistance Performance Paradigm (RPP). In particular, I found that the network in the northeastern community displayed characteristics of RPP but did not construct a “multiplex” of coordinated resistance as had emerged in past RPP research. I interviewed 20 activists in order to assess how the northeastern network was different from previous RPP research, and whether such differences accounted for the lack of a multiplex of coordinated resistance. The interviews revealed that the network was fractured over (a) what issues to address and (b) how to approach/protest any such issues. Further data analysis revealed that the fractures stemmed in part from activists' uncertainty about a listserv used by all of the activists in the network. Such findings constitute an additional characteristic of RPP: the capacity of a network to efficiently circulate narratives to all points in a network. 相似文献

Experts claim that the world is increasingly polarized by emerging social media platforms. The political actors amplify the polarization through their agents' user-generated content. The extreme political ideologies sway the people sitting on the fence on these social media platforms. Using tweets on a recent policy change on identity in India, the present study seeks to perform a scientific analysis of the polarization of the debates within ordinary citizens' groups from a theoretical lens. We further highlight some of the crucial trends that triggered these polarized discussions in general. Through the lens of Echo chambers and Herd behavior, this study provides valuable insights surrounding the influencers and individuals involved in this discussion where the polarization of preferences is witnessed. Proposing a novel design of a root-level influencer, this study establishes them as polarization actors on a social media platform (Twitter). Through various engagement metrics, we also identify the role of targeted communication (hashtags) and similarity in the users' discussion across the political domain as potential behavioral explanations for opinion polarization on Twitter. 相似文献

This article discusses the results of a survey designed to assess the current state of electronic access to government information from both the specialist and the user viewpoint. The first survey, designed to determine the government documents staffs' level of commitment to and opinions of electronic access to government information, was distributed in electronic format to subscribers of GOVDOC-L, a listserv for specialists dealing with government documents. The second survey, designed to provide insight into the user's point of view, was conducted at the University of Illinois Documents Library. This article synthesizes earlier studies and articles on the topic to show that while the consensus is that electronic access represents a positive, beneficial move toward providing access to government information to a wider audience, there is also an acknowledgment that there are many inherent problems that have not been addressed adequately. 相似文献

The substantial increase in nested data such as egocentric network data pose unique challenges to researchers, including how to adequately model the mechanisms and processes in which hypothesized effects operates within the complex interdependencies among social actors. While there is a growing interest in identifying the causal mechanisms and their contingencies using such nested structured data, the direct application of principles of (moderated) mediation analysis within traditional multilevel modeling framework is ambiguous and controversial. In this article, I provide a tutorial illustrating an approach to assessing mediation hypotheses based on path-analytic framework popularized by Hayes (2013). Focusing on estimation and inference of indirect effects with regard to nested data structure, I provide examples of the analysis within the context of egocentric network data, and illustrate implementation using Mplus software. 相似文献

MCN‐L, an email listserv administered by the Museum Computer Network, is open to anyone interested in discussing information technology in museums and other cultural heritage organizations. To determine how MCN‐L meets the needs of museum information professionals, this study presents an analysis of more than 6,000 emails sent to the listserv over a seven‐year period (2004–2011). The results of this analysis indicate that MCN‐L adds value to the online community of museum information professionals by providing an online communication channel focused on professional outreach and expert support, backed up by specific examples drawn from personal experiences. MCN‐L's emphasis on personal expertise is a key characteristic that speaks to the listserv's lasting value to the museum community and has implications for researchers and practitioners as they consider the future of computer‐mediated communication for all museum professionals. 相似文献

从社会建构论的角度来看,人的情绪虽然以生物性反应为基础,但主要是社会建构的结果。文化和语言是建构情绪的重要手段。个体情绪借助语言在社会网络间传播,实质是一场以情绪理解为内核的群体情感互动仪式。互联网群体传播帮助人们通过建立弱关系扩大社会网络,促进个体情绪在传播范围上的量变和情绪性质上的质变,形成社会情绪型舆论。网络语言具有表层和深层双重情绪基因,通过模因复制进行群体传播。在此过程中,网络语言具有三重效应:一是凝合效应,促进深层情绪整合,形成社会舆论;二是转移效应,其表层的娱乐性、游戏性特征能推动情绪转化,疏导社会舆论;三是沉淀效应,累积社会情绪氛围,沉淀社会参与基因,建构网络语言所诞生和维护的社会文化。 相似文献

Despite ample research on brand engagement via social media, little research considers the aggregate effect of multiple same-brand accounts on engagement. Multiple same-brand accounts are common because they allow brands to extend their reach, tailor their messaging, and cross-promote their products/services. Therefore, this study tests whether interaction between same-brand social media accounts and centrality within same-brand conversational networks is related to user engagement. An analysis of 3,380 brand accounts found that after controlling for interactions with users, interactions between brand accounts contributed significantly to user engagement and that account centrality measures were associated with measures of engagement. 相似文献
