The media are normatively expected to play significant roles in conflictual discussions within national and international communities. As previous research shows, digital platforms make scholars rethink these roles based on media behavior in online communicative environments as well as on the structural limitations of the platforms. At the same time, traditional dichotomies between information dissemination and opinion formation roles, although seemingly universal, also vary across cultures. We look at four recent conflicts of comparable nature in the United States, Germany, France, and Russia to assess the roles that legacy media have performed in the respective ad hoc discussions on Twitter. Our approach differs from previous studies, as we combine content analysis of tweets by the media and journalists with the resulting positions of the media in the discussion graphs. Our findings show that, despite the overall trend of the “elite” and regional media sticking to information dissemination, online-only media and individual journalists vary greatly in their normative strategies, and this is true across countries. We also show that combining performance in content and social network analysis may allow for reconceptualization of media roles in a more flexible way. 相似文献

本文以日本在十五年战争期间的"总体战"体制为背景,探讨"舆论动员"活动的相关问题。通过对日本战时社会历史的考察发现,日本军部以德国的总体战体制为蓝本,将媒体宣传和意识形态引导作为舆论动员机制的核心指导方针,以相关传媒法令为法律依据,通过对各类媒体机构的整合,将媒体资源纳入战争的轨道。封建资本主义制度下的专制语境形成了舆论动员机制的政治基础,军国主义的国民精神结构是舆论动员的思想动力,在媒体将政治意图转化为媒介议题的过程中,媒体精英和意见领袖也发挥了引导作用。多种机理共同运作之下,舆论动员机制实现了对战时国民精神的强效果控制。 相似文献

基于共现分析的网络议程设置研究从认知心理学的角度出发,分析媒体议程与公众议程网络,更加贴近回答李普曼所说的“我们脑海中的图景”,但该方法只能体现议程网络中关键词间的显性关系。本文提出通过基于上下文语义的word2vec模型,测度网络议程设置中关键词隐性关系的研究方法。以“红黄蓝事件”为例,揭示党媒、都市类媒体、商业媒体、知乎意见领袖以及公众的议程网络及其相似度。研究发现,知乎意见领袖对公众议程的影响程度最大,其议程主要是对事件背后因果关系的梳理以及对策建议的提供。在媒体方面,党媒和都市类媒体报道基本一致,且二者对公众的影响均高于商业媒体。本研究是对现有网络议程设置研究的补充,对议程设置的本土化研究有一定的启示。 相似文献

In keeping with end-of-century biographies of great leaders, this essay traces the careers of opinion pollster George Gallup and journalism educator Ralph Nafziger. They inadvertently overlapped in 1930, by publishing the first Journalism Quarterly articles on newspaper readers. Gallup became internationally recognized as creator of the Gallup Poll and other media audience enterprises. He invented some standard questions that are used in academic as well as commercial research today, and "a new form of journalism" built around public opinion on current events. Nafziger, as a professor and administrator, built research centers and graduate programs in 2 leading journalism schools. He was central to the establishment of research as an integral component within education for journalism and mass communication. 相似文献

Affordable and ubiquitous online communications (social media) provide the means for flows of ideas and opinions and play an increasing role for the transformation and cohesion of society – yet little is understood about how online opinions emerge, diffuse, and gain momentum. To address this problem, an opinion formation framework based on content analysis of social media and sociophysical system modeling is proposed. Based on prior research and own projects, three building blocks of online opinion tracking and simulation are described: (1) automated topic, emotion and opinion detection in real-time, (2) information flow modeling and agent-based simulation, and (3) modeling of opinion networks, including special social and psychological circumstances, such as the influence of emotions, media and leaders, changing social networks etc. Finally, three application scenarios are presented to illustrate the framework and motivate further research. 相似文献

British newspapers have been criticised for their coverage of the European Union and accused of contributing to the strength of anti-European opinion in the United Kingdom. Despite these claims, research by media sociologists and political communications scholars has commonly focused on news reporting, overlooking editorial opinions on European issues. This article addresses this gap by presenting a sociological analysis of editorial journalism in relation to European integration at 10 British national newspapers. The findings show that newspapers vary widely in the resources and roles they have assigned for editorialising on Europe, and provide an original insight into the common routines employed for producing editorial opinion. A model, entitled the editorial production process, is developed to illustrate the key stages of this routine. The specialist practices of editorial journalism are discussed through the identification of a set of editorial values used to select issues for comment. 相似文献

The present research developed a measure for exposure to both antisocial and prosocial media content by revising and extending a previous Content-based Media Exposure Scale (C-ME). The validity and reliability of the C-ME2 was tested in two independent samples (N = 678), among young adults (Study 1) and adolescents (Study 2). Results of Confirmatory Factor Analyses showed good fit, in both studies, for both antisocial and prosocial dimensions of media content, and for both males and females. Furthermore, the C-ME2 explains unique variance beyond previous measures of violent and general media exposure. Evidence is presented of reliability, discriminant and predictive validity of the C-ME2, measuring both frequency and exposure to specific content of media. The C-ME2 covers all media platforms, is easy to use in all research designs, and allows for standardization and systematic comparisons across studies. 相似文献

Sharing of knowledge, information, and practices across cultural and national boundaries has become a means to address critical global problems. As government agencies increasingly collaborate with international counterparts on these issues, transnational knowledge and information sharing networks grow in importance as mechanisms for collaboration. This paper explores the nature of transnational public sector knowledge networks (TPSKNs) and identifies critical contextual factors that shape their performance. In these networks, each participating organization operates within complex national, organizational, and information contexts. The contextual differences between participants produce distances in culture, politics, intentions, organizational factors, relationships, knowledge, resources, geography, and technology. These distances influence their ability to engage in the processes and interactions that are essential to network performance. The paper concludes with a conceptual dynamic model that accounts for the relationships among these factors that can guide further research in understanding knowledge and information sharing across national and cultural boundaries. 相似文献

This article contributes to the understanding of how transnational media corporations enter, operate, and are structured in different national contexts. Specifically, it provides a detailed examination of News Corporation's use of sport as an instrument for successfully penetrating national television markets within the United States, the United Kingdom, and Australia. The discussion is divided into 3 sections, focused on (a) the cultural and economic rationales underpinning News Corporation's use of sport as a core aspect of transnational television market entry strategies, (b) examples of News Corporation's use of sport programming to enter and manage local media markets, and (c) the changes wrought in News Corporation's organizational structure and focus resulting from its transnational sporting orientation. 相似文献

As long as scholars have studied media, issues of access have been of great concern. Recent advancements in digital technology have framed disparities in access within the digital divide research and knowledge gap frameworks. While early digital divide research looked at access, more recent research has focused on how media are used differently across populations. The current research extends this literature by examining media expectancies across ethnic subgroups for a broad range of media (i.e., local newspapers, national newspapers, network television, cable television, radio, magazines, and Internet). Data indicate expectancies differ among African Americans, Caucasians, and Hispanics. 相似文献

Cultural proximity is a multidimensional concept, most often used to explain media preferences across national boundaries. The present study extends the construct, revealing its power to explain audience formation within a multicultural society. Portable People Meter data from Arbitron, Inc., was used to compare patterns of television and radio use across Spanish-speaking Hispanics, English-speaking Hispanics, and non-Hispanics in Houston, Texas. The results indicate that language preferences play a powerful role in determining audience behavior. Furthermore, while English-speaking Hispanics exhibit multicultural fluency, the other two populations show evidence of cultural polarization. 相似文献

Since the introduction of the opinion leadership conceptualization,both practitioners and academics have been keenly interestedin its applicability in modern society. Numerous studies havebeen conducted to identify potential opinion leaders, learnof the characteristics distinguishing them from their ‘followers,’and understand how they exert their personal influence to changeopinions and behaviors of the masses. Despite the growing researchon opinion leadership, the identification of appropriate opinionleaders for practical purposes continues to be a challenge.Several methods were used to identify opinion leaders. The existenceof numerous methods and their use in various societies, socialsettings and cultures and the variance across domains of opinionleadership raises questions on the applicability and validityof the modern, advanced measures when applied to other socialsettings. The present study is in fact a first attempt to applythe modern personality strength (PS) scale to a traditionalcommunity. The PS scale was found to be an efficient, valid,and useful instrument to identify opinion leaders in numerousstudies. However, it was always used, tested, and validatedin Western societies (e.g., Germany, USA, and Israel). Whenwe applied the method in the Skukuza community, a small villagein South Africa, the findings revealed the inapplicability ofthe scale in a traditional community. Several factors are suggestedto explain the futility of the PS scale in a traditional society. 相似文献

电视会终结吗?——新媒体时代电视传播模式的颠覆与重构 总被引：1，自引：0，他引：1
电视会终结吗?这是伴随着新媒体时代到来而浮出水面的一个问题。事实上,新媒体时代可能带来的不是电视媒体自身的终结,而是传统电视传播模式的终结。未来电视的传播将不再是基于频道和栏目(节目)的单向线性传播,而是基于碎片化信息的、由电视媒体及其观众两大主体共同完成的多级传播。 相似文献

Momentary assessment data collection methods can capture information about constructs that vary greatly throughout the day. The Measuring Youth Media Exposure methodology implemented multiple momentary measures of media use in addition to a time use diary (TUD), allowing evaluation of the convergent and divergent validity of these momentary assessment methodologies relative to the TUD. This article presents the reliability and validity of momentary questionnaires and momentary video recordings of media use in relation to conventional TUD using an adaptation of the multi–trait-multi-method matrix. Both momentary measures show good reliability as well as convergent and discriminant validity for assessing TV, video game, computer, and cell phone use in adolescents relative to the TUD. 相似文献

Altmetrics have been proposed as a way to assess the societal impact of research. Although altmetrics are already in use as impact or attention metrics in different contexts, it is still not clear whether they really capture or reflect societal impact. This study is based on altmetrics, citation counts, research output and case study data from the UK Research Excellence Framework (REF), and peers’ REF assessments of research output and societal impact. We investigated the convergent validity of altmetrics by using two REF datasets: publications submitted as research output (PRO) to the REF and publications referenced in case studies (PCS). Case studies, which are intended to demonstrate societal impact, should cite the most relevant research papers. We used the MHq’ indicator for assessing impact – an indicator which has been introduced for count data with many zeros. The results of the first part of the analysis show that news media as well as mentions on Facebook, in blogs, in Wikipedia, and in policy-related documents have higher MHq’ values for PCS than for PRO. Thus, the altmetric indicators seem to have convergent validity for these data. In the second part of the analysis, altmetrics have been correlated with REF reviewers’ average scores on PCS. The negative or close to zero correlations question the convergent validity of altmetrics in that context. We suggest that they may capture a different aspect of societal impact (which can be called unknown attention) to that seen by reviewers (who are interested in the causal link between research and action in society). 相似文献

Non-governmental organizations (NGOs) are deeply embedded within the socio-political landscape of India. NGOs were instituted by the Indian government specifically for the purpose of nation-building at the time of national independence in 1947 (Muttalib, 1987). In recent times however, NGOs have come under much scrutiny because of the expanding neoliberal agenda, and global discourse surrounding NGOs often involves questions of accountability. Communication scholars have studied NGOs in various contexts, but what remains unexplored is the question of how NGOs are portrayed within the media, which in contemporary society constitutes the public sphere or space of public opinion. It is important to look at the media because public legitimacy can have serious consequences for an NGO's ability to garner funds, influence policy, and build trust in beneficiary communities. This study thus asks the research question: How are NGOs framed in the Indian media? A qualitative analysis was employed to identify news frames or ‘interpretive packages’ used to talk about NGOs in two of the most widely-circulated English daily newspapers in India. The analysis identified four frames: the ‘do-good’ frame, protest frame, partner frame, and the public accountability frame. The findings show that, for the most part, NGOs are represented in a positive and even a nationalistic light, in spite of the larger global discourse interrogating NGO practices. The discussion elaborates on institutional, political, and historical reasons why NGOs are portrayed favorably in the newspapers. 相似文献

This study features the development and validation of a multidimensional scale for Perceived News Media Importance (PNMI), a concept pertaining to how much individuals personally value normative functions of political/public affairs journalism. Comprised of six different dimensions that represent the weight of what citizens deem to be desirable about news work, the PNMI concept exhibits the capacity to strengthen scholarly explanations about the public’s perceptions of the news media and related democratic outcomes. More specifically this research, which employs three data sets, is designed to (1) explicate the PNMI concept, (2) develop and validate a PNMI scale, (3) and explore PNMI’s predictive value relative to news media use and support for freedom of the press. Evidence of validity is confirmed with media trust, political media use, political interest, and ideology. Furthermore, PNMI is shown to be predictive of (a) mainstream and social media-based news use, as conditioned by perceptions of the press satisfactory performing normative functions, and (b) support for press freedoms. While the hypothesized PNMI model (as a higher order latent construct with six lower order dimensions) exhibits a sound model fit, a combined data set (total N=912) reveals that PNMI could also be treated as a multi-factor, lower-order latent construct. 相似文献

To maintain relevancy with the ever-increasing competencies required of them, librarians on the job have frequently turned to professional development (PD) opportunities. One outlet that could potentially address barriers librarians face when accessing PD is social media, which can help librarians communicate across distances, are used at low to no cost, and can be accessed asynchronously as needed. Drawing from 25 studies conducted in 21 countries, this systematic literature review explored the empirical themes evident in the current research on librarians' adoption of social media for PD purposes. This review found (1) there is considerable potential in adopting social media for PD across contexts; (2) studies focused on the affordances provided by social media in areas where there is limited infrastructure, support, and resources for PD; (3) in congruence with prior research pertaining to the Technology Acceptance Model, librarians who felt more tech-savvy were more likely to adopt social media for PD; and (4) social media was viewed as democratic in creating a platform where diverse voices could participate. The paper concludes with a discussion of the implications for practitioners and recommendations for future research directions. 相似文献
