Serials standards work: the next frontier     

Tseng SC  Arcand JL  Brugger JM  Finn M  Olson AJ  Somers S 《Library resources & technical services》1990,34(2):139-157

Serials, one of the more complicated areas of library technical endeavors, has lacked the benefit of standards for a long time. Even now, with standards beginning to be available, the majority of institutions are not working within standard serials formats. A survey to determine the use of serials standards in libraries was conducted in 1988 by the American Library Association, Resources and Technical Services Division, Serials Section, Committee to Study Serials Standards. In the spring of 1988 a survey was sent to a group encompassing the Association of Research Libraries members, CONSER participants, United States Newspaper Program participants, Microform Project libraries, and some vendors and librarians who attended the Committee meetings on a regular basis. The survey questionnaire assessed the current level of serials standards awareness of librarians and vendors. Topics included the type of serials systems used, standards relevant to serials control and union listing and whether or not they are implemented, types and levels of training staff received in the application of standards, benefits of the standards, and areas where standards are most needed.  相似文献   

Normative behavior and information: The social aspects of information access     

Gary Burnett  Paul T. Jaeger  Kim M. Thompson 《Library & information science research》2008,30(1):56-66

Information access is central to library and information science, yet explorations of its conceptual nature have been limited. Given the importance of information access to the discipline, there is a need for research to create a better understanding of the concept and its many roles in all activities and behaviors related to information. Drawing on the theoretical work of Elfreda Chatman, this article proposes that the study of information access can be facilitated through the recognition and examination of the physical, intellectual, and social aspects of information access. These types of access are examined through three case studies in terms of different information behaviors and contexts, with a particular focus on the importance of social access. The article also discusses the future roles that considerations of social access can play in research and theory.  相似文献

彻底简化IT     

David M.Upton  尚丹 《信息系统工程》2008,(10)

如何实现"简化IT"的战略,这是困扰很多企业,尤其是CIO的一个重要问题。本文以日本新生银行的例子来诠释如何彻底简化IT。中世纪哲人William of Ock- ham说过,理论应该尽可能的简单。同样的原则适用于企业IT系统:它们按照尽可能少的标准  相似文献   

基于二部图的搜索引擎排序欺骗检测算法     

陶剑文  方程 《情报学报》2008,27(4)

"链接工厂"欺骗(Link farm spam)和重复链接严重地损坏了像HITS这样基于链接排序的算法性能.为了检测与抑制Web"链接工厂"欺骗和重复链接,本文充分利用页面之间的复制信息,尤其是利用完全超链接信息识别可疑链接目标.提出一种由页面文档和完全链接构成的二部图结构,通过对二部图进行构建与分析,搜寻共享锚文本和链接目标的Web页面,在此过程中标识链接工厂和重复链接,并通过带惩罚因子的权重邻接矩阵减小可疑链接的影响.实时实验和用户仿真测试结果显示,本文算法能显著改善传统HITS类方法的信息搜索质量.  相似文献

On rubrication of the division <Emphasis Type="Italic">spintronics</Emphasis> in a separate edition of the abstract journal of the VINITI RAS <Emphasis Type="Italic">solid-state physics</Emphasis> (<Emphasis Type="Italic">Electrical Properties</Emphasis>)     

N. M. Builova  E. M. Epshtein  V. G. Shamaev 《Scientific and Technical Information Processing》2008,35(1):28-29

The necessity for publishing a separate abstract journal on spintronics, which is a new, rapidly developing branch of physics, is substantiated. The interest in spintronics, which is the study of fundamental processes involving the simultaneous transport of both electron charge and electron spins in solids, as well as the interaction of electrons with a magnetic grating, is determined not only by its fascinating prospects but also the results that have already achieved. The spin and charge “degrees of freedom” open possibilities for the creation of semiconducting devices with parameters that are much superior to the existing ones and also the construction of devices that do not have analogues at present. First of all, this will permit problems of information transmission and processing to be solved in a new way. A detailed rubrication on spintronics is given in order to discuss the possibility of publishing a separate edition of an abstract journal devoted to spintronics.  相似文献   

基于长尾理论的数字图书馆用户保障   总被引：10，自引：0，他引：10  

Cheng Juan  肖雪 《图书情报工作》2008,52(8):39-39

长尾理论关注小众市场和用户的思路为数字图书馆的用户保障提供了新视角,在实现信息服务总体目标、应对信息市场的竞争形式和顺应信息服务的个性化趋势方面具有重要的启示意义。在信息生产、信息船体和信息供求的长尾驱动下,通过识别和细分用户、完善信息资源体系、高效揭示和检索信息、注重用户个性化服务,长尾理论能为数字图书馆用户保证提供现实指导。  相似文献   

图书馆为弱势群体提供知识援助:市场经济体制下的“悖论”   总被引：1，自引：0，他引：1  

程建民 《河南图书馆学刊》2008,28(4)

图书馆是国家或政府为了保障公民的知识权利而选择的一种制度安排.为弱势群体提供知识援助正是这种制度安排意义的体现.但在社会经济体制变迁的过程中,受市场经济浪潮的冲击和影响.图书馆精神衰微,为弱势群体提供知识援助很可能成了一句无法兑现的"美丽的诺言".对此.图书馆应从制度建设入手.进行制度创新,以保障知识援助的有效开展.  相似文献
