分类检索语言的断言与非断言性--从标引中的两个实例谈起

知识的微分化和科学概念内涵的衍化只是扯外部提供了一些发展空间，分类法的断言性完全可以将它们消化在近缘的类和不同的种中。因此，断言惟为分类法提供了一个稳定的状态，使分类法能在一个时期内发挥分类检索的作用。分类法中，一个个类目组成一个个集合住标引时先于文献而抽象地存在着。每当新元素添加进集合中，这个集合都要被修正。此时，这些元素将不再处于合适的类目内，而且必须移动它们。显然分类法还存在着非断言性，分类法的发展动力来自分类法自身的非断言性。     

论网站信息咨询服务模式

目前,对于网站信息咨询概念的认识尚不统一。网站信息咨询的主要模式有:基于资源重组的知识化信息服务,依托应用系统的智能化服务,基于用户需求的个性化服务,基于实时联动的交互式咨询服务等等。网站咨询服务具有快捷方便、超越时空、动态发布、资源共享、智能管理、安全可靠、实时交互、服务主动等优点。其存在的问题主要表现于思想认识、经费投入和技术、法规保证方面。参考文献8。

英语学术界的若干论著体例及其启示-对建立中文学术规范体系的思考

文章介绍了英语学术界流行的若干论著体例,包括MLA、APA、Chicago、Vancouver、Harvard、Oxford等体例,指出英语学术界的学术规范体系对于中文学术规范体系的建立具有很强的借鉴意义。应在遵循基本规范的前提下保持各学科领域体例的相对自由和独立,积极发挥学术团体在规范制订中的作用,在强调规范约束力的同时加强对作者与编者的教育与指导,早日建立起中文学术界科学合理的学术规范体系。

也谈谓词隐含及其句法后果问题--与袁毓林先生商榷

袁毓林前些年对有价名词以及名词性偏正词组中谓词隐含等问题所进行的研究，确实反映了本学科的新进展及前沿性成果。然而这种研究毕竟属于纵深探讨性质。事实上，中心语只有具备[ 转让]语义特征时，提取宾语且隐去谓词的“的”字结构才能称代它。该词组中谓词隐合并非普遍性的，典型领有关系的才可能有这种潜在的句法述谓性质。关于“的”字结构，我们赞同朱德熙先生“自指”“转指”语义类型的区分，并给予了进一步的证明。     

Comparison of three web-scale discovery services for health sciences research

Objective

The purpose of this study was to investigate the relative effectiveness of three web-scale discovery (WSD) tools in answering health sciences search queries.

Methods

Simple keyword searches, based on topics from six health sciences disciplines, were run at multiple real-world implementations of EBSCO Discovery Service (EDS), Ex Libris''s Primo, and ProQuest''s Summon. Each WSD tool was evaluated in its ability to retrieve relevant results and in its coverage of MEDLINE content.

Results

All WSD tools returned between 50%–60% relevant results. Primo returned a higher number of duplicate results than the other 2 WSD products. Summon results were more relevant when search terms were automatically mapped to controlled vocabulary. EDS indexed the largest number of MEDLINE citations, followed closely by Summon. Additionally, keyword searches in all 3 WSD tools retrieved relevant material that was not found with precision (Medical Subject Headings) searches in MEDLINE.

Conclusions

None of the 3 WSD products studied was overwhelmingly more effective in returning relevant results. While difficult to place the figure of 50%–60% relevance in context, it implies a strong likelihood that the average user would be able to find satisfactory sources on the first page of search results using a rudimentary keyword search. The discovery of additional relevant material beyond that retrieved from MEDLINE indicates WSD tools'' value as a supplement to traditional resources for health sciences researchers.

“Montrose” child life protection unit: A treatment and assessment model in child abuse intervention

In New South Wales, Australia, the Department of Youth and Community Services is empowered by statute to deal with cases of child abuse and neglect. Its child protection services include the Montrose Child Life Protection Unit which is designed to support and complement the work of both the Intake Service, Field Service and most importantly the work of child protective facilities in the community. The service has intake crisis counselling and call out resources; maintains a central register; provides a facility for crisis residential care for children and families, diagnostic assessment, and a day programme. The emphasis in service delivery in New South Wales in the area of child protection is on multidisciplinary intervention. The Department of Youth and Community Services is involved in promoting interagency cooperation and co-ordination. Over and above a philosophy that underlies service delivery is the Montrose Unit's involvement in sensitising the community to the difficult and often demanding role of parenting. Montrose represents an attempt to create an environment where parenting myths can be examined from a reality base and strategies implemented for reeducation.
