COUNTER R5的新特性及对图书馆的影响

COUNTER是规范网络化电子资源使用统计报告数据处理、审核和提交的国际化标准,是图书馆电子资源使用量统计和评估的核心要素。目前COUNTER已经发布了最新版本R5,了解R5的新特性及与之前版本的不同对于图书馆的电子资源统计工作具有重要意义。本文拟从COUNTERR5的报告设置、报告的指标类型、数据类型、访问类型和其他完善报告的属性来解析R5,同时介绍R5对SUSHI收割的影响、"持续维护"的概念、R5发布对图书馆的影响和R5实施的重要时间节点,同时也对R5较之R4的发展和不同进行了比较和分析。COUNTERR5的主要关注点是一致性、清晰性和简单性,较之COUNTERR4有了明显的完善,同时包含了持续的维护过程,允许对代码进行更新而不必再引入一个全新的版本,解决了版本升级会对供应商和图书馆带来的各种时间和人员成本的影响。     

Placing Facebook

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.     

Press Credentials and Hybrid Boundary Zones: The Case of WorldNetDaily and the Standing Committee of Correspondents

ABSTRACT

Press credentialing practices are a vital, yet understudied site of scholarly research on journalistic norms and practices. Press credentialing not only structures internal professional hierarchies, but they also signify the boundaries of the journalistic field itself. This paper explores the legal and theoretical implications of press credentialing to cover the United States Congress, drawing on the concepts of boundary work and journalistic authority to demonstrate the material impact of the space between fields on professional legitimation in journalism. Using WorldNetDaily (WND) as a case study, I argue that the Standing Committee of Correspondents (SCC) occupies a hybrid boundary zone between the journalistic and political fields, generating a unique tension in First Amendment jurisprudence that places journalists in a paradoxical role as both the professional embodiments of free speech and its constitutional steward. The resulting jurisdictional conflict between the SCC and WND extends the relational model of journalistic authority by articulating how journalist-state relations can fundamentally augment the process of legitimation at its fuzzy boundaries. The relevance and implications for press credentialing practices in the digital age are discussed.
