ABSTRACT

The development of web 2.0 was powered by web services that are software systems designed to support interoperable machine-to-machine interaction over a network. It was the choice of standards enabling such interactions that favored communication among different systems and their mash ups. Facebook was the first social networking site to launch a service for developers that exposed its web services and the correlated APIs (application programming interfaces). This choice allowed programmers to create tools that could live within Facebook and turned the social networking site into a platform by enacting its programmability. In order to investigate the possibilities and the constraints offered by social media platforms, there seems to arise the necessity to integrate the analysis of frontend texts (such as posts or comments) and of social media communicative properties with the exploration of an underlying layer constituted by the network of relationships created within an application ecosystem and developed by using web services. The aim of the paper is to present a multi-layered approach to the study of social media platforms that combines the emerging subfield of Semiotic Technology with Platform Studies. The model is here applied to the analysis of Facebook Login Service.  相似文献

The purpose of this study is to investigate the relationship between social media usage for work purposes and employee job satisfaction in the public sector. Because social media is a relatively recent phenomenon, the ways in which it affects employee attitudes such as job satisfaction are not well-known. Using self-determination theory (SDT) as a framework, this study tests whether perceived competence, relatedness, and autonomy mediate the relationship between social media usage for work purposes and employee job satisfaction. Data were obtained from the Australian Public Service Commission (APSC). Overall, results generated from the structural equation models support SDT, suggesting that employees using social media for work purposes have higher self-determination and higher self-determination increases their job satisfaction. In particular, the effect of competence to job satisfaction is very high. However, while social media usage for work purposes can enhance employees’ need for autonomy and competence, it does not have any statistical effect to employees need for relatedness. In addition, social media does not have any statistical and direct effect to job satisfaction. The results suggest that social media has an indirect effect to job satisfaction. This article discusses the implications of these findings.  相似文献

Political agenda‐setting research has shown that policy makers are responsive vis‐à‐vis media priorities. However, the mechanisms behind this effect have remained understudied so far. In particular, agenda‐setting scholars have difficulties determining to what extent politicians react to media coverage purely because of the information it contains (information effect), and to what extent the effect is driven not by what the media say but by the fact that certain information is in the media (media channel effect), which is valued for its own sake – for instance, because media coverage is considered to be a reflection of public opinion. By means of a survey‐embedded experiment with Belgian, Canadian and Israeli political elites (N = 410), this study tests whether the mere fact that an issue is covered by the news media causes politicians to pay attention to this issue. It shows that a piece of information gets more attention from politicians when it comes via the media rather than an identical piece of information coming via a personal e‐mail. This effect occurs largely across the board: it is not dependent on individual politician characteristics.  相似文献

The hostile media effect (HME) has generally been tested in terms of in-groups and out-groups, with a “neutral” story in between. This ignores the nature of many social groups as comprising subgroups, often but not always sharing feelings of connectedness and purpose. In cases when bounded subgroups are at odds with one another, HME provides little guidance. A contested partisan primary provides such a case. This study takes identity centrality, candidate favorability, and perceived social network homogeneity as measures of partisanship and involvement, hypothesizing relationships between each and perceived bias against one’s candidate and party. Findings show that markers of candidate-focused social identity predict greater perceived bias against one’s candidate during the 2016 primary season, while party-focused identity fails to predict perceived bias against one’s party. This suggests that candidate support identity overrides plain partisanship during primaries, supporting concern that a heated primary might damage general election party unity. Subsequent postconvention findings suggest that the salience of candidate-focused identity fades, while homogeneity of one’s network regarding party support helps to make perceived hostility toward one’s party identity more salient. However, as campaigns become more candidate-centered, the contestation between nested candidate and party identities may grow fiercer.  相似文献

In the United States participatory budgeting (PB) is a relatively new and innovative approach to municipal budgeting that has implications for improving the role of citizen participation in the budgetary process. The research is based on personal interviews with local community leaders involved in the PB process in the 49th Ward of Chicago, Illinois; the 6th Ward of St. Louis, Missouri; and the City of Boston, Massachusetts. Highlights are provided of the specific experiences and perceptions of these community leaders with a particular emphasis on the use of social media platforms in engaging citizens in the PB process. This article concludes with recommendations for creating a PB infrastructure, for increasing citizen participation in the PB process, and for assessing and increasing the impact of PB in cities within the United States.  相似文献

Media coverage of Supreme Court decisions is not well-understood, with studies typically focusing on features of decisions such as issue area and opinion authorship, and ignoring the political and legal importance of those decisions. Because the Court is both secretive and esoteric, and because it does not engage in traditional public relations activities, media must proxy importance by looking to available cues, such as interest group participation. Importantly, some indicators of importance are available before a decision is rendered; thus I examine both pre- and post-decision media coverage of cases. I show that expected legal and political impact drive media coverage of Court decisions, and that the decision-level features that prior studies have focused on are much less important in determining coverage than has been previously thought.  相似文献

In the debate on minimal media effects and their causes, methodological concerns about measurement are rarely discussed. We argue that even in state-of-the-art media-effects studies that combine measures of media messages and media use (i.e., linkage analyses), measurement error in both the media content analysis and the media use self-reports will typically lead to severely downward-biased effect estimates. We demonstrate this phenomenon using a large Monte Carlo simulation with varying parameters of the content analysis and the survey study. Results show that measurement error in the content analysis and media use variables does indeed lead to smaller effect estimates, especially when the media messages of interest are relatively rare. We discuss these findings as well as possible remedies and implications for future research.  相似文献

Since 1989, many of the former communist countries in Central and Eastern Europe (CEE) have made the dramatic change from communist regimes to democratic nations that are integrated in the European sphere. While these sweeping changes have given rise to a successful transition to democracy unlike any the world has ever seen, there remain issues with governance as well as citizen support for the regime. While other studies have shown that mass media can influence a person's attitudes and opinions in the region, none has explored what effect social media can have on orientations toward democracy in the region. In the following paper, I build several hypotheses based on previous studies of media effects and democratic survival. I then employ survey data to empirically test whether social media increases support for democracy. The study finds that not only does using social media increase support for democracy, but also simple usage rather than information seeking provides more consistent effects on a person's support for democracy in CEE.  相似文献

It is a well-known fact that the transition to and consolidation of democracy in Latin America have been problematic, especially at the subnational level. It is also commonplace to equate an independent media system with a strong democracy. While each of these fields has witnessed important developments in the last decade or so, there have been sparse attempts to draw the theoretical links between them. In this article, I argue that there are important insights to be gained from such an endeavour. Bahia, a state in north-eastern Brazil, is an ideal case study to bring these perspectives together. This study offers fresh insights on state–society relations at the subnational level and on the contemporary interaction between the public and the private spheres in Latin America. Last but not least, it will also provide a better grasp on the challenges democratization faces at the subnational level and the role of the media in them.  相似文献
