Abstract

This article describes how electronic resources have impacted the University of Nevada, Las Vegas (UNLV) Libraries' binding operation and how the libraries have responded to the resulting challenges, including the need for updated collection development and preservation/conservation policies, a comprehensive bindery contract, and a fully functional in-house binding capability. The evaluation of the binding process must continue as libraries move from a predominantly print to a predominantly electronic environment. Librarians, scholars, and binders should work together to preserve and bind library collections that will be valuable to future generations.

自适应的Ad hoc MAC协议

为Adhoc网络提出了一种基于模糊逻辑的媒体接入控制层协议。该协议通过在MAC层采用模糊逻辑协调各个相互影响的数据流,为低优先级数据流选择附加退避窗口以减少其自身接入信道概率。通过这种方法,使得高优先级数据流在各种背景流量的条件下,均能够维持较高的端到端吞吐量和较低的端到端接入时延。仿真结果表明,该协议较802.11e协议更好地保护高优先级数据流的端到端时延和吞吐量。

VisualFoxPro是为数据库结构和应用程序开发而设计的功能强大的面向对象的环境。本设计将Visual FoxPro数据库技术于高校学籍管理系统的开发,利用其可视化的设计工具和表单向导,快速创建出应用程序“学生学籍表”。该表单反映了学生的基本情况和各门课程的成绩。在该表单中还可以进行查找、打印、添加、编辑等操作,具有一定的实用性。     

教育资源库检索结果的评价技术研究

对教育资源库的检索结果评价是各种教育资源库检索性能评价方案中最直接的方法。该文在总结目前教育资源库的四种主流检索方式的基础上,分析了传统信息检索的特征,结合教育资源库的网络化、海量化发展趋势,借鉴网络搜索引擎评价技术中的“相关性范畴”和“前X命中纪录查准率”概念,提出了一种基于考察替代查准率来对教育资源库检索结果进行评价的方法。     

Searching for Elder Abuse: A Systematic Review of Database Citations

ABSTRACT

The aim of this review was to describe trends and patterns in elder abuse literature and research. All citations in PUB MED, CINAHL, and PsycINFO databases located using the search term “elder abuse” were retrieved (3,059 citations) and 2,418 unique references were identified. Using manifest content analysis, non-research material (1,986 references) was sorted by type and research references (34 dissertations and 398 research articles) were categorized. Research article references most commonly: (1) investigated prevalence, typology, and definitions of elder abuse; (2) utilized quantitative methodology; (3) had first author affiliations to medicine, nursing, and social sciences; and (4) sampled populations of professionals, personnel, cases, or charts. The USA was most frequently listed of 24 identified countries of origin. Elder abuse research shows lack of diversity, slow increase of qualitative research, limited involvement of older persons and family members as participants, and minimal research from developing countries. This review contributes to knowledge valuable for researchers and experts planning future studies or elder abuse projects.

Healthcare in India: Changing the Financing Strategy

The way in which healthcare is financed is critical for equity in access to healthcare. At present the proportion of public resources committed to healthcare in India is one of the lowest in the world, with less than one‐fifth of health expenditure being publicly financed. India has large‐scale poverty and yet the main source of financing healthcare is out‐of‐pocket expenditure. This is a cause of the huge inequities we see in access to healthcare. The article argues for strengthening public investment and expenditure in the health sector and suggests possible options for doing this. It also calls for a reform of the existing healthcare system by restructuring it to create a universal access mechanism which also factors in the private health sector. The article concludes that it is important to over‐emphasize the fact that health is a public or social good and so cannot be left to the vagaries of the market.
