ABSTRACT

The Mediated Social Communication (MSC) approach considers mass media a venue for opposing and complementary societal groups to publicly negotiate socially relevant topics. This negotiation is conducted through representatives of these groups and mediated by journalists. Inspired by the MSC approach, this paper presents an empirically grounded model that structures the mediating process through the process of quoting. By identifying the key phases of newswriting as sub-processes of quoting, the paper argues that journalists (1) decide on a topical issue to be addressed (topicalisation), (2) identify groups of people who are linked to this issue (societal localisation), (3) pick some people as representatives of these societal groups (personalisation), and (4) verbalise these people's points of view, often by means of quoting, inter alia (verbalisation). The four-phase model is then operationalised into a data collection method that facilitates access to and fosters new insights into the subtle dynamics of newswriting. Hitherto, these dynamics have often remained obscure, because the craft ethos is adopted as tacit knowledge through implicit socialisation and is therefore difficult for journalists to verbalise. The paper concludes by calling for reconsideration of journalists’ role as gatekeepers who decide which issues and voices are heard in public discourse.  相似文献

《反兴奋剂运动员权利规则》是由世界反兴奋剂机构下属的运动员委员会制定,执行委员会批准通过的首个明确规定运动员在反兴奋剂活动中权利的文件。作为运动员参与反兴奋剂活动的基础,该文件的制定与修订争议不断,多集中于文件名称、法律地位及其内容中不具有强制执行力的部分。在体育组织的干预下,起草者修改了文件的名称并澄清“这不是一份法律文件”,使该文件的意义与价值存疑。建议在日后的修订中慎重考虑文件名称的匹配性,在厘清该文件与《世界反兴奋剂条例》及国际标准关系的基础上,赋予其法律效力或给予象征性法律规则的地位,完善对受侵犯权利救济的指引,加快建立申诉处理机制。  相似文献

Participants from the Netherlands (n = 52), China (n = 50), and South Africa (n = 166) either read a self-targeted or a family-targeted fear appeal message about chlamydia. Seven aspects of individual cultural orientation were measured, and six effects of the different messages. Interactions between nationality and target of threat were found on perceived severity, perceived susceptibility, and danger control. Only for perceived susceptibility, a difference in cultural orientation partly explained this interaction. The outcomes add to the doubts about claims in earlier literature about the relevance of receivers’ nationality and cultural orientation for developing a fear appeal message.  相似文献

ABSTRACT

Nearly everyone agrees that physical pain is bad. Indeed, if anything merits the status of a platitude in our everyday thinking about value, the idea that pain is bad surely does. Equally, it seems clearly true that emotional suffering – despair, loneliness, grief, disappointment, guilt, shame, lovesickness, and the like – are all bad as well. We are strongly inclined to pity and feel sorry for those who suffer emotionally in these ways; we are motivated, at least some of the time, to do what we can to alleviate their suffering. Given this, it might seem curious that pain and suffering are so integral to sport – whether one is a participant or a spectator. There’s nothing particularly puzzling about pain and suffering that is inadvertently related to sport – as when an athlete injures her hamstring and has to miss her chance at Olympic glory, or when supporters face the misery of getting up at 6am because an away game has been scheduled to start at noon. But there does seem to be something curious about the extent to which pain and suffering are voluntarily embraced by participants and spectators, as the quotation from Nick Hornby aptly illustrates. Why do people willingly engage in something that brings about so much suffering? In this paper, I’ll attempt to answer this question.1  相似文献

This study investigates how journalists covering international humanitarian crises make decisions regarding what types of information to include in stories. Specifically, the inclusion/exclusion of solutions-oriented information is addressed, since crises represent a key time during which the potential for international engagement is discussed in the mainstream media. Interviews with journalists covering hunger crises in Africa reveal an internal tension between maintaining a neutral, unbiased position and writing in a way that supports engagement and action. Ironically, perhaps, journalists find that including solutions-oriented information amounts to unethical and biased coverage, despite the fact that inclusion of solutions to social problems is an accepted and institutionalized aspect of the US news media’s mandate to the public. Reasons for this seeming contradiction are discussed, and I argue that solutions-oriented information not only can be included without demonstrating bias, but that it ought to be included to support ethical coverage that properly informs citizens about potential paths for political engagement.  相似文献

ABSTRACT

Bullet-screen technology, an innovative way of interacting with online videos, allows viewers to contribute comments that simultaneously appear over videos. Popular in East Asia, the technology is making its way to American audiences. This study employed a comparative qualitative focus group approach to explore how American and Chinese viewers responded to and interacted with this new format of online videos. Three themes emerge from this investigation: (1) the unique affordances of this technology; (2) barriers to adoption and usage; and (3) cultural differences that impact the user experience. The theoretical and practical implications for bullet-screen technologies are discussed.  相似文献

ABSTRACT

This study operationalized Weick’s [(1988). Enacted sensemaking in crisis situations. Journal of Management Studies 25(4), 305–317 and (1993). The collapse of sensemaking in organizations: The Mann Gulch disaster. Administrative Science Quarterly, 38, 628–652] theory of enacted sensemaking to examine the communication processes associated with the Flint Water Crisis of 2014–2015. A content analysis of 389 emails and attachments from a total population of N?=?37,376 pages of publicly released e-mails and documents pertaining to Flint’s water issues, identified examples of failed sensemaking by government officials. These failures hastened and intensified a growing crisis of lead contamination and an outbreak of Legionnaires disease associated with Flint’s municipal water system. Analysis of email messages suggests that strong commitments by top leaders and limited capacity were important factors as were efforts to create and maintain consensus among officials. The Flint Water Crisis offers an important application of sensemaking theory and its utility for both organizational and risk communication scholars and for practical application. The authors emphasize the importance of questioning previous assumptions and commitments, insuring that communication practitioners are involved in decisions, and avoiding over reliance on image repair as a strategic response.  相似文献
