网络传输的方向是群对群传输研究

网络传输可以分为四种形态：“一对一”,“多对一”,“一对多”和“多对多”。“一对一”是问题分解的终极,而“多对多”则是效率所追求的终极。由四种形态之间转变展开讨论,为了提高效率,网络传输应该转向“多对多”。群对群是“多对多”的另一种传输方式,或者说,是强调分群的“多对多”传输。

文本主题可视化及其在上市公司风险分析中的应用

使用可视化的方法,从词汇的粒度去发现和描述主题,指出属于同一个主题的词汇之间存在集聚特性,使用转置向量空间中的邻近关系表示这种集聚特性,进而使用多维尺度分析的方法将词汇之间的邻近关系投影到低维的MDS空间图中,以使有集聚关系、从属于同一个主题的词汇在空间图中聚类成主题。最后,将该方法成功应用于计算机应用服务业上市公司的风险分析,揭示该行业市场风险的具体表现和语义内容。     

Web Accessibility Assessment of Urban Public Library Websites

In an age of ubiquitous information and communication technologies, urban public libraries are some of the only places to provide free Internet access for all members of the community regardless of ability or disability. This study provides a website accessibility assessment of the 127 U.S. public library members of the Urban Library Council, using the World Wide Web Consortium’s Web Content Accessibility Guidelines to establish the level of Web readiness of urban public libraries to meet the needs of individuals with disabilities. Findings suggest these libraries require additional and ongoing maintenance to be digitally inclusive.

The Role of Public Librarians in Disseminating Information for True Democracy

Disseminating information should be the business of public librarians. In a democracy, public librarians are expected to play a leading role in acquiring, processing, interpreting, repackaging, and disseminating relevant, up-to-date, and timely information and knowledge resources both from within and beyond their localities. Public librarians should serve as catalysts for the effective dissemination of information to promote true democracy. They are expected to explore channels of communication for the practice of true democracy. An emphasis on democratic ideals raises awareness of democratic tenets among the populace and also facilitates the holding of free, fair, and peaceful elections. This article examines the concept of democratic governance, the link between democratic governance and information, public libraries, and what public librarians should do to ensure the promotion of democracy.     

An Evaluation of Young Adult Web Pages in Public Library Websites in Japan

This study is the first investigation into the types of contents in young adult (YA) web pages in public library websites in Japan. The study reveals that YA web pages, in general, place more emphasis on providing guidance on YA services, on helping young adults with regular learning, on the use of information resources for reference services, and on improving the communication abilities for young adults, rather than on providing research assistance to adults on YA services. Furthermore, an IRIS (Information Reference Instructional Sharing) Contents Model is proposed for YA web pages, whereas an IRIR (Information Reference Instructional Research) Contents Model is presented for children’s web pages, based on the differences between the contents of YA web pages and those of children’s web pages.     

Statewide Initiative to Embed Consumer Health Librarians in Public Libraries: A Case Study

In 2004 a collaborative, statewide outreach project in Delaware was undertaken where consumer health librarians were embedded in public libraries. In order to explore the effect of the embedded librarians on the quality of health information provision, unobtrusive reference visits were made to half of the public libraries in the state. The query “Do vaccines cause autism?” was posed to library staff; resources provided were recorded. In 67 percent of visits, public library staff provided authoritative health information resources. It appears the embedded librarians had a positive residual effect on the provision of authoritative health resources for addressing an ambiguous query.     

基于信息公平的东中西部公共图书馆公平服务评价研究

在阐述信息公平与公共图书馆公平服务基本概念基础上,构建公共图书馆公平服务评价指标体系,并利用《中国图书馆年鉴2012》和《中国统计年鉴2012》的数据,运用相对差距综合指数法对我国东中西部公共图书馆进行评价,即从“投入—产出—受益”3个方面对我国不同区域公共图书馆的公平服务状况缺少,得出东部地区内部各省份发展不均衡,中部地区在投入最少的情况下产出与受益服务较强,西部地区产出进行分析和受益服务较弱的结论。     

微博个体信息传播影响力评价指标分析

微博已经成为网络舆情产生的重要平台,其中具有强信息传播影响力的个体对网络舆情发展走势有着关键性影响。以3种类型微博个体2013年8月的微博数据作为研究对象,对5种传播影响力评价指标进行分析,发现同一评价指标的有效性具有一定适用范围,并受到微博个体类型的影响。建议在构建新的评价指标或模型时,应充分考虑待评价个体的类型的影响,以有助于提高评价结果的精准性。
