This article explores the existence of a “citizen-centered journalism” that sees citizens as crucial participants in the construction of news and as co-creators of their own worlds. Through qualitative case studies of three news organizations, the article examines the motivation for using a citizen-centered approach, the news routines that are required to do so, the categories of content produced, and the perceived impact of this approach. The results suggest these news organizations are working in partnership with communities and striving to give a voice to historically marginalized communities. The journalists, however, see citizen participation as complementary to professional journalistic routines that favor verifiable information, rather than assigning inherent value to it for its own sake. 相似文献

The emergence of “fake news” during the Brexit referendum and Trump election campaign sent news organisations scurrying to establish teams of journalists to debunk deliberately misleading stories and verify facts. This paper examines steps to counter false stories and asks whether normative values of objectivity are about to enjoy a comeback. Typical markers of objectivity (freedom from bias, detachment and fact-based reporting) date back to the nineteenth century and, despite being ingrained in the Anglo-American news culture, have always been subject to challenge. Recently, the growth of partisan and populist media has illustrated deep distrust in traditional news outlets and is questioning whether it is time to jettison objectivity. But are we experiencing a backlash? Through interviews with senior UK-based journalists at legacy news organisations and analysis of editorial policy statements prompted by a UK parliamentary inquiry, the paper explores how fake news is rekindling debate about objectivity and its potential to make quality journalism stand out. It argues that legacy news organisations in the United Kingdom have seized the opportunity to highlight the value of normative practices that draw on familiar components of the objectivity paradigm. But few have the financial strength to bolster the rhetoric with additional editorial resources. 相似文献

Facebook is challenging professional journalism. These challenges were evident in three incidents from 2016: the allegation that Facebook privileged progressive-leaning news on its trending feature; Facebook’s removal of the Pulitzer Prize-winning “Napalm Girl” photo from the pages of prominent users; and the proliferation of “fake news” during the US presidential election. Using theoretical concepts from the field of boundary work, this paper examines how The Guardian, The New York Times, Columbia Journalism Review and Poynter editorialized Facebook’s role in these three incidents to discursively construct the boundary between the value of professional journalism to democracy and Facebook’s ascendant role in facilitating essential democratic functions. Findings reveal that these publications attempted to define Facebook as a news organization (i.e., include it within the boundaries of journalism) so that they could then criticize the company for not following duties traditionally incumbent upon news organizations (i.e., place it outside the boundaries of journalism). This paper advances scholarship that focuses on both inward and outward conceptions of boundary work, further explores the complex challenge of defining who a journalist is in the face of rapidly changing technological norms, and advances scholarship in the field of media ethics that positions ethical analysis at the institutional level. 相似文献

针对当前石油公司在液货船安全检查和准入审查中存在的非定量、非智能评估问题,引入人工智能技术构建液货船综合安全评估(formal safety assessment, FSA)专家系统模型。该模型将FSA方法与专家系统进行组合,前者通过风险识别、风险衡准和风险量化,解决报告的非定量评估和审查的主观性问题;后者引入K最近邻算法、加权赋值算法等解决审查评估的非智能化和效率低的问题。选取官方案例进行模型检验,其结果表明提出的模型能有效地帮助石油公司实现船舶准入审查的定量化、智能化,并能显著提高审查效率,降低人工评估的主观性影响。 相似文献
