The present research investigated whether co-viewer comments in social TV interactions are able to enhance or weaken media effects. With the example of talent shows, the valence of co-viewer comments (pro/contra/none) as well as the type of content (antisocial behavior vs. conventional performance) were varied in an experiment (N = 117). Results showed that participants’ own comments and their private attitudes about the judges varied in line with comment valence. Findings suggest that social TV viewers are prone to social influence of their co-viewers, which might amplify problems regarding the portrayal of antisocial behavior in reality TV. 相似文献

The notion of social media affordances has not been fully integrated into the uses and gratifications literature. Building on the MAIN (modality, agency, interactivity, and navigability) model, this study develops and tests a social media uses and gratifications scale with a sample of 393 college students. Results of the study support the MAIN model, as conceptualizing social media uses and gratifications as a second-order factor structure with 4 different types of affordances displays similar goodness-of-fit to a single-order factor structure. A confirmatory factor analysis with a second sample of 313 adults further confirms the applicability of the scale among the general population. 相似文献

This article is principally concerned with how and why these 2 types of radio news developed. It discusses the culture, ethos and practices of the 2 services and, in particular, if and how each was influenced by the other. Much of the article is concerned about how the new commercial stations developed practices and styles that were consciously different from, and in some cases in direct opposition to, those at the BBC, both nationally and locally. The article argues that it was the BBC which adopted and integrated commercial radio’s style and practices, rather than, as is often supposed, the other way around. 相似文献

Scientific collaboration can only be understood along the epistemic and cognitive grounding of scientific disciplines. New scientific discoveries in astrophysics led to a major restructuring of the elite network of astrophysics. To study the interplay of the epistemic grounding and the social network structure of a discipline, a mixed-methods approach is necessary. It combines scientometrics, quantitative network analysis and visualization tools with a qualitative network analysis approach. The centre of the international collaboration network of astrophysics is demarcated by identifying the 225 most productive astrophysicists. For the years 1998?C1999 and 2001?C2006 four co-authorship networks are constructed comprehending each a two year period. A visualization of the longitudinal network data gives first hints on the structural development of the network. The network of 2005?C2006 is analyzed in depth. Based on cohesion analysis tools for network analysis, two main cores and three smaller ones are identified. Scientists in each core and additionally in structurally interesting positions are identified and 17 qualitative expert interviews are conducted with them. The visualization of the network of 2005?C2006 is used in the interviews as a stimulus for the interviewees. An analysis of the three most often used keywords of the 225 astrophysicists is included and combined with the other data. The triangulation of these approaches shows that major epistemic changes in astrophysics, e.g. the discovery of the accelerating expansion of the universe, together with technical and organizational innovations, leads to a restructuring of the network of the discipline. The importance of a combination of qualitative and quantitative network analysis tools for the understanding of the interplay of cognitive and social structure in the sociology of science is substantiated. 相似文献

This paper considers the changing role of universities in the UK as they respond to an engagement agenda that stipulates a more immersive and visible interaction between academics and the public. It constitutes a survey of attitudes to public engagement in a selection of UK universities drawing on interviews with senior academics with managerial responsibility at the end of 2009. The results of this study reflect a mood of indecision and anxiety among respondents towards a public engagement agenda seen to influence the contours of their professional identities and working lives. The study situates academic accounts that contest the legitimacy of public engagement as a core academic activity and the role of academics in communicating with public groups. Moreover, it reveals a lack of agreement and consistency in the conceptualisation and application of public engagement in higher education contexts, certainly beyond an emergent discourse of research impact. 相似文献
