OBJECTIVES: Medicine must keep current with the research literature, and keeping current requires continuously updating the clinical knowledge base (i.e., references that provide answers to clinical questions). The authors estimated the volume of medical literature potentially relevant to primary care published in a month and the time required for physicians trained in medical epidemiology to evaluate it for updating a clinical knowledge base. METHODS: We included journals listed in five primary care journal review services (ACP Journal Club, DynaMed, Evidence-Based Practice, Journal Watch, and QuickScan Reviews). Finding little overlap, we added the 2001 "Brandon/Hill Selected List of Print Books and Journals for the Small Medical Library." We counted articles (including letters, editorials, and other commentaries) published in March 2002, using bibliographic software where possible and hand counting when necessary. For journals not published in March 2002, we reviewed the nearest issue. Five primary care physicians independently evaluated fifty randomly selected articles and timed the process. RESULTS: The combined list contained 341 currently active journals with 8,265 articles. Adjusting for publication frequency, we estimate 7,287 articles are published monthly in this set of journals. Physicians trained in epidemiology would take an estimated 627.5 hours per month to evaluate these articles. CONCLUSIONS: To provide practicing clinicians with the best current evidence, more comprehensive and systematic literature surveillance efforts are needed.  相似文献

This paper discusses some key issues for digital archives and metadata in a networked information environment to keep our community memory for the future. The paper is based primarily on the experiences and lessons learnt by the author from his research activities on metadata and digital archives. The author participated in a study group on digital archives hosted by the Ministry of Internal Affairs and Communications of the Japanese Government from February 2011 to March 2012. The group discussed the promotion of digital archives in Japan, particularly at memory institutions. The Great East Japan Earthquake of 11 March 2011 caused serious damage in the north-eastern part of Japan, especially the Pacific coastal regions. This disaster significantly affected the discussions of the group. The basic lesson that the author learned is that digital archives built on a robust information environment are essential for keeping our community memory safe for the future. Not only do the primary digital resources need to be properly maintained and preserved for the future but also secondary resources, metadata and meta-metadata. We need to use Linked Open Data technologies to enhance the usability of such digital resources in the archives.  相似文献

Historically, libraries have purchased most of their books from wholesalers catering to the library market. In the past five years, new web booksellers have entered the marketing offering deep discounts and rapid delivery to the general public. Purchasing from web vendors tends to increase library administrative costs because of institutional credit card and auditing policies, double data entry on the web vendor’s interface and local library system, and other factors. Depending on local administrative costs, libraries may find web vendors the best choice for purchasing OP, foreign and rush titles.  相似文献

This work collates the opinions of European professionals and internet users concerning the changing reality facing the world of journalism following the explosion of digital media. Our research shows the results of analytical surveys conducted between October 2013 and January 2014 among 54 professionals of renowned prestige, and 500 regular users of the digital media in the five most populated countries in the European Union: Germany, United Kingdom, France, Italy and Spain, all states affected to a greater or lesser extent by the crisis of the printed press. The surveys cover a wide range of topics, from the impact of social networks, the quality of the digital media, the willingness of citizens to pay for content and the degree of interactivity in the digital media for the future of journalism. Professionals and users agree that the news in 2020 will be better and more interactive than now. With regard to other matters, there is more disagreement. Professionals are much more critical than users when it comes to evaluating the quality of the news. The professionals’ survey was more qualitative, and, in their opinion, overcoming the crisis in the written press implies, among other measures, promoting analysis, prioritising quality over quantity and offering “niche” specialisation.  相似文献

Discussion about the value of electronic documents is often hampered by starting from what is usual in the paper world and attempting to impose that on an electronic environment. In order to grasp the impact of the current electronic revolution, and formulate a policy for the future, we examine the aims and content of scientific communication. We then critically discuss the recommendations of an International Working Group [see Learned Publishing 2000:13(4) Oct. 251–8], and show the tension between these very reasonable recommendations and the reality of electronic publishing. We conclude that the scientific article will change considerably but that, in its new more composite form as an ensemble of various textual and non-textual components, it will retain many of the current cultural and scientific requirements with regard to editorial, quality and integrity.  相似文献

ABSTRACT

In 1994, the librarians at the University of Toledo's Carlson Library developed a bibliographic instruction program that is both efficient and successful. “Teach the Teachers” has been implemented in the English Department's Composition classes where it depends on the collaborative efforts between librarians and classroom instructors in assuring solid student library skills. The program philosophy shifts a librarian's teaching efforts from teaching the student to teaching the instructor. Librarians empower classroom instructors with the knowledge to teach basic information retrieval skills. This paper will discuss the development of the program, as well as the techniques used by both librarians and classroom instructors.  相似文献

ABSTRACT

The article relates how the Brooklyn Campus Library of Long Island University, despite limitations of physical distance and the varying conditions of the remote graduate campus at Westchester, makes every effort to face each challenge creatively with practical solutions for implementation. We share our findings and experiences—what worked and what did not—and what remains to be done in terms of supporting the curricula and bringing library resources and services to a mixture of remote site users. The authors recount how the gap between reality and the ideal is reduced and unique issues relevant to remote users are resolved by the Brooklyn Campus Library, in collaboration with other units of Long Island University. We relate how we combine library instruction with our marketing efforts to promote library resources and services. We also analyze survey data and interlibrary loan statistics to assess our success. The article contributes to the ongoing discussion of improving and promoting library resources and services to remote sites.  相似文献

The Way to Open Access - French Strategies to Move Forward   总被引:2,自引:0,他引:2  
In France, the movement in favour of open access to scientific research output is getting increasingly coordinated and supported at the political level. The CNRS, a leading research organization in Europe and signatory of the Berlin Declaration, has an evident strategic role to play in this development. Various initiatives that have emerged in the French academic world in recent years have led, for example, in early 2005 to the joint announcement, by four major research institutions, of a common policy to promote open access to published material and other types of digital resources, and to set up institutional archives. The article highlights some key issues of this policy, gives an overview of the current and past CNRS involvement in open access and describes the principal functions, as well as the related challenges, of the future institutional repositories.  相似文献

A recent survey by Broadcasting of television programming personnel indicates that professionals in the broadcasting field agree with the general public in holding that the Kennedy‐Nixon debates during the late presidential election campaign were among the most exciting programs ever presented on television. We know that the audiences to these “great debates” were among the largest ever recorded, but sheer numbers do not tell us why audiences paid attention to these debates in the first place, much less the potential and actual effects of these programs.

The following article is one of a number being prepared by the members of the Communications Research Center at Michigan State University, covering a great many facets of political behavior in the 1960 campaign and election. The author of the following article, Dr. Lionel C. Barrow, Jr., is Assistant Professor in the Communications Research Center.  相似文献

Drawing from my experiences as President of the Central States Communication Association, I examine how service allows for opportunities to create relationships, identity, and leadership in profound ways. I then consider how Communication scholars can unite to resolve ongoing economic issues that threaten both communication pedagogy and research. The academy as a whole faces serious economic challenges; this essay identifies some of these specific problems and potential action steps that academic associations can take in an advocacy role on this front. This is done in the hope that associations or even individuals begin (or continue) thinking about what they can do to help address the economic issues in higher education that so many face across the academy.  相似文献

This paper presents the results of two complementary surveys undertaken in 2008 as part of a wider project investigating the effects and impact of open access to research outputs in the UK. The institutional view, from a survey of academic librarians, is compared to researchers' perceptions and practices. Researchers were largely unaware of their institutions' policies with regard to open access, or whether they had an institutional repository. Reasons for making research outputs available on open access, or not doing so, were sought, and the role of open access material as a research resource investigated. The surveys found that many researchers maintained a suspicion of open access publications, both as authors and as users of scholarly material, together with a degree of ignorance about open access and the role of institutional repositories. This suggests that a degree of culture change may be needed, as institutions develop repositories with a view to future research assessment requirements, and more funders adopt open access mandates for the outputs from research which they fund.  相似文献

我1987年3月开始业余写新闻稿,到1988年12月,一年多的时间里,被《中国青年报》《人民公安报》《北京日报》和北京人民广播电台等市以上新闻单位采用稿件67篇,被市公安局和延庆县委宣传部评为优秀通讯员。回顾写稿的实践,我的初步体会是“捡”“精”“思”“闯”“挤”这五个字。写作的知识靠“捡”。写文章缺乏必要的基础知识,即使遇到好的题材,头脑这个加工厂再灵,也出不了名牌产品。为了“捡”知识,我除了备有“阅报本”“读书笔记”,注意随时把  相似文献
