我国优秀少年足球守门员出击技术运用情况分析     

杨磊  张强  沈培森  董向荣 《山东体育科技》2004,26(1):11-12,21

运用现场观察和常规技术统计的方法，对目前国内优秀少年足球守门员出击技术运用情况进行统计和分析，并提出建议。研究表明，对出击时机的把握性差和对抗中争接球技术运用质量水平低，是目前我国优秀少年足球守门员出击技术运用中存在的主要问题。守门员把握出击的时机，是与其对门前赛势的观察、判断及分析密不可分的，只有正确地分析门前的情况，才能把握住出击的时机。少年守门员出击意识、心理及技术应同步发展，切实提高出击的机变能力，应是少年守门员训练中的重点。应加强少年守门员对抗中的技术运用质量要求，努力改变比赛中守门员技术不过硬的现状。  相似文献

Back to the Future     

Stephen Jukes 《Journalism Practice》2018,12(8):1029-1038

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   

Placing Facebook     

Brett G. Johnson  Kimberly Kelling 《Journalism Practice》2018,12(7):817-833

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

Temporary Book Storage Using a Document Management Company     

Meredith Giffin  Kirsten Huhn  Andréa Harland 《资料收集管理》2019,44(1):46-68

Finding an appropriate temporary storage location for books and providing access to them is a significant challenge for libraries undergoing renovations. The current article describes the use of a document management company by an academic library to store 430,000 books for 8 months and provide a retrieval-on-demand service. Aspects covered include the selection of a commercial storage provider with its own retrieval service; details of the move to and from offsite storage; the integration of the service with library processes; communications and user feedback; book usage during the storage period; overall costs; and lessons learned from the experience.  相似文献
