Several long-standing theories intersect in discussing the impact of community characteristics and of the mass media. The structural pluralism model popularized by Tichenor and his colleagues says that social structure influences how mass media operate in communities because they respond to how power is distributed in the social system, whereas the linear model says that the increasing size of a community's population leads to more social differentiation and diversity and corresponding increases in subcultures with their own beliefs, customs, and behaviors. Recently, there has been a concern about how changes in society have led to a decline in organizational activity and the network of relationships and trust that constitute “social capital.” This article examines the impact of population and diversity (using census data) on individuals’ media use, interpersonal discussion and civic engagement (measured in a national survey), and the relationship among these variables. Analysis of a structural model provides evidence that the “linear hypothesis” can be combined with structural pluralism, with size—measured by population—impacting diversity, which influences the relationships that people have with their community. Concurrently, social categories influence people's communication patterns and community relationships, and communication impacts civic engagement. 相似文献

After the Spring Festival of 2015, an environmental documentary called Under the Dome in which Chai Jing acted as a narrator has caused the public opinion to boom in social media in China. Why could a documentary released by internet attract so much attention and spark such a heated discussion? What are the factors that have influence on the information dissemination of social media environmental mobilization? This paper employed case study and semi-structure interviews to reveal these questions. It turned out that individual trust, group norms and information networks of the social capital played an important role in the social media environmental mobilization. The reason why Under the Dome became a hot issue was that it made full use of the social media users’ trust on the mobilizer, aroused the mobilized’s emotions and combined the network channels of social relationships. 相似文献

The spiral of silence (SoS) framework elaborates the factors that determine whether individuals are willing to express their opinions in public. Although previous scholarship has examined differences in between face-to-face and computer-mediated communication, research studies have rarely tested how perceived affordances of the channel influence whether individuals express opinions or self-censor. In this study (N = 399), we examine several propositions of SoS within the context of discussing police discrimination on Facebook. To extend the theory’s relevance to social networking sites, we examined how users’ perceptions of network association, social presence, anonymity, and persistence related to opinion expression. Findings indicate support for some of the theory’s original tenets, as well as the role of multiple perceived affordances in determining whether people will express an opinion to their online social network. We discuss the implications for measuring and understanding political expression and silencing on social media as well as offline. 相似文献

Retaining users of mobile government services (MGS) is critical to the success of mobile government. Drawing on Bagozzi's self-regulation framework, the current research investigates the predictors of MGS continuance by considering both perceived quality and perceived value. Unlike most e-government research that has utilized linear models, this study employed a two-stage structural equation modeling–artificial neural network approach that can identify non-linear and non-compensatory interactions. The current research first applied a structural equation model to examine the significant factors influencing MGS continuance, and then utilized a neural network model recheck the structural equation modeling findings and rank the importance of these factors. Data were obtained from 335 “one-stop-shop service platform” app users in China through an online survey platform. The research findings reveal that user satisfaction is the utmost influential determinant of their continuous-use intention regarding MGS, followed by user trust; moreover, perceived quality and perceived value strongly influence satisfaction and trust. However, perceived risk does not affect intention to continue use. We also discuss theoretical and practical implications for government agencies and service providers, for improving user continuance rates for MGS. 相似文献

While repositories’ efforts to build trustworthy digital repositories (TDRs) led to the establishment of ISO standards, much less research has been done regarding the user’s side, despite calls for an understanding of users’ trust of TDRs. In order to learn about users’ perspectives on trust in digital repositories, the present study investigated users’ definitions of trust and factors that influence users’ trust development, particularly addressing the users of three data repositories in the United States. A total of 19 participants were interviewed in this study. The results of this study indicate that users’ definition of trust is largely based on a lack of deception, when it comes down to the specific context of data repositories. Regarding factors influencing the development of users’ trust in repositories, organizational attributes, user communities (recommendations and frequent use), past experiences, repository processes (documentation, data cleaning, and quality checking), and users’ perception of the repository roles were identified. 相似文献

ABSTRACTIn this paper, we address algorithmic imaginary, perception and tactics of Italian dating apps users. Little attention has hitherto been devoted to the ways in which the algorithms employed by mobile dating platforms (to rate users, to manage user visibility, to arrange results) might contrast, or enhance, people’s homophily. Our goal is to explore whether and how mobile dating algorithms modify the perception of what we define as “relational filter bubbles”; and whether, and how, users believe dating algorithms reshape (extend or limit) the heterogeneity of their intimate interactions. The paper builds on literature addressing online dating, the datafication of society, the rise of the so-called quantified self, and of the algorithmic culture. We organized 4 focus groups involving Italian dating apps users, who reported a variety of sexual orientations and of dating apps usage. Overall, while dating apps’ algorithms operate in an opaque way, participants developed an “algorithmic imaginary”. Moreover, they appreciate the role of mobile dating apps in reinforcing their relational homophily (their tendency to like people that are “similar” to them), whilst, at the same time, mainly using these apps for increasing the diversity of their intimate interactions in terms of extending their preexisting networks. 相似文献

This study investigated how social media use and online social capital might have influenced social trust and risk perception of a public health crisis in China. It also tested the validity and reliability of the online social capital measurement in the context of a Chinese food-safety crisis. Study findings validated the impact of online social capital on social trust and risk perception. In addition, two new dimensions of online social capital scale were identified; these two dimensions are in parallel to Putnam’s [2000. Bowling alone: The collapse and revival of american community. New York: Simon and Schuster] conception of ‘bonding social capital’ and ‘bridging social capital.’ Social and policy implications of the study results are discussed. 相似文献

This study applies social network analysis to examining the pattern of relationships among networked users on Sina Weibo, the most popular social networking site in China. Focusing on verified (or V-) users and ordinary (non-V-) users, this study maps three centrality attributes of the social network, in terms of in/out degree, closeness, betweenness, along with cliques, in the dissemination and sharing of health-related information in the virtual community. Findings reveal a ‘spider web’ pattern of relationship among 50 V-users and 50 non-V-users during a regular period of time, highlighting the dominant position of the V-users for health-related information diffusion. Data analysis then reports a ‘drifting dandelion’ pattern of network among those who shared the information about a health-related incident on Weibo. This study also provides further information about the topical categories of health-related messages shared during the regular period as well as the topics concerning the incident. The implications of social networking media for health communication are also discussed. 相似文献

ABSTRACT The online environment has radically changed the way in which users consume, discover and manipulate news. The growing relevance of social media platforms and digital intermediaries for news sharing and consumption increase the likelihood of citizens to be exposed to online news even when they are not seeking it. This digital transformation fundamentally challenges the way online news use and exposure have been conceptualized and measured, affecting also to citizens’ knowledge about public affairs and politics. This article examines the factors that predict the probability to be an “incidentally exposed news user” online. Specifically, based on a representative US sample from the Pew Research Centre, this study analyses the role of media preference, use and trust. Findings indicate that beyond users’ demographics and loyalty, readers’ news preferences, uses and trust, specially of social media platforms, affect their probability to be incidentally exposed to news online. These results have important empirical and theoretical implications for understanding the connection between readers’ news consumption patterns and online exposure, intentional or incidental. 相似文献

Studies of social networks highlight the importance of network structure or structural properties of a given network and its impact on performance outcome. One of the important properties of this network structure is referred to as social capital, which is the network of contacts and the associated values attached to these networks of contacts. This study provides empirical evidence of the influence of social capital and performance within the context of academic collaboration (coauthorship) and suggests that the collaborative process involves social capital embedded within relationships and network structures among direct coauthors. Association between scholars' social capital and their citation-based performance measures is examined. To overcome the limitations of traditional social network metrics for measuring the influence of scholars' social capital within coauthorship networks, the traditional social network metrics is extended by proposing two new measures, of which one is non-weighted (the power–diversity index) and the other (power–tie–diversity index) is weighted by the number of collaboration instances. The Spearman's correlation rank test is used to examine the association between scholars' social capital measures and their citation-based performance. Results suggest that research performance of authors is positively correlated with their social capital measures. The power–diversity index and power–tie–diversity index serve as indicators of power and influence of an individual's ability to control communication and information. 相似文献
