Let It Flow: The Monopolization of Academic Content Providers and How It Threatens the Democratization of Information     

Dana Lachenmayer 《期刊图书馆员》2019,75(1-4):70-80

The monopolization of academic journal publishers concentrates power and valuable information into the hands of a few players in the marketplace. It has detrimental effects on how information flows and is accessed. This, in turn, has profound effects on how a nation progresses. Placed in a theoretical framework, utilizing the marketplace of ideas and the economies that coincide, this article takes a look at the history of Elsevier in order to chart this course toward monopolization. It exhibits the effect it has already had on the academic community, while offering two models of Open Access as a much sounder option.  相似文献   

Health information seeking behaviour: the librarian's role in supporting digital and health literacy     

Rachel Butler 《Health information and libraries journal》2019,36(3):278-282

This paper is based on Rachel Butler's dissertation carried out at the University of Sheffield as part of the MA Library and Information Services Management. The study examines people's online health information seeking skills, with the specific aim to identify how libraries and health services can work together in supporting digital and health literacy. A survey approach is used to explore online searching habits as well as librarian and health professionals’ views on health literacy. The key findings indicate that whilst the majority of respondents consider themselves to be health literate, there was an overall agreement that effective education and support could be achieved through the collaboration between libraries and health services, and specifically to signpost information and to provide targeted education. The limitations of the research for dissertation are recognised leading to recommendations that further study focuses on the impact of signposting and education on health literacy.F.J.  相似文献   

Ugandan health libraries in the 21st century: key initiatives and challenges     

Alison Annet Kinengyere 《Health information and libraries journal》2019,36(2):185-189

This article is part of a series in this regular feature which looks at new directions in health science libraries. This paper highlights new initiatives aimed at ensuring health libraries can contribute to the development of Uganda in the 21st century and the challenges facing libraries. It stresses that for libraries to be successful they need to form networks and collaborations for resource sharing; take advantage of the benefits of information technology; computerise their library systems; as well as invest in the development of staff. The paper highlights the main challenge facing the library service as inadequate funding both from government for public‐funded health libraries and the private sector (for privately funded health libraries). The paper concludes that, despite the bottlenecks brought about by inadequate funding, Ugandan health libraries have taken positive steps to support health research and education, as well as patient care, not just for Uganda, but for the whole of the East African region.

TDD-CDMA 系统中基于业务统计的联合功率控制算法     

陈波  戎蒙恬  胡威 《上海大学学报(英文版)》2008,12(5):414-418

An important feature of the traffic in mobile networks is burstiness. Drawbacks of conventional power control algorithms for time division duplex （TDD）-code division multiple access （CDMA） systems are analyzed. A joint power control algorithm based on service factor is presented to address the TDD-CDMA mobile services in the burst mode according to the Markov modulated Bernoulli process. The joint power control equation is derived. A function model is developed to verify the new algorithm and evaluate its performance. Simulation results show that the new power control algorithm can estimate interference strength more precisely, speed up convergence of power control, and enhance power efficiency and system capacity. It is shown that the proposed algorithm is more robust against link gain changes, and outperforms the reference algorithms.  相似文献

GATS协议对我国旅游业国际投资的保护     

周维维 《绵阳师范学院学报》2007,26(3):103-106

GATS作为WTO框架下的多边国际条约,对其签约国的国内有关旅游服务贸易的立法具有约束的作用,要求各成员国删去其国内旅游服务贸易立法中对旅游服务贸易的市场准入方面限制的条款,同时在外来旅游服务性投资项目建立起来之后,给予该投资项目公平的、非歧视性的待遇。这对于我国的旅游业对外投资在进入东道国市场的时候以及进入后享受到公正的非歧视性的待遇具有重要的作用。但由于GATS妥协性的特性,它在国民待遇、市场准入和补贴等方面规定模糊,因此在对旅游业国际投资的实际保护上的作用仍有待提高。  相似文献   

对开放教育法学专业实践性教学环节--课程实践环节的思考     

张建飞 《湖南广播电视大学学报》2004,(3):19-21

课程实践环节是开放教育试点法学专业实践性教学环节的一部分，是整个教学过程的组成部分，也是实现应用型专门法律人才培养目标的一个重要环节；同时该环节又是开放教育试点法学专业的一个薄弱环节。因而，加强对该环节的研究，对于深化课程教学模式改革，保证试点教学质量，有着一定的意义。  相似文献
