Assessing books’ depth and breadth via multi-level mining on tables of contents

Compared with journal articles, books can provide broader, deeper and more comprehensive information, and often have higher expertise and academic depth. However, most researches on book assessment focus on measuring academic value of books (e.g. citations analysis) or identifying attitudes of readers (e.g. book review mining), depth and breadth reflected by book contents is neglected. Therefore, in this paper, we measure books’ depth and breadth by mining books’ tables of contents, so as to enrich resources and methods for book assessment research, help users understand book contents quickly and improve efficiency of book selection. Specifically, we measured books’ depth and breadth based on books’ tables of contents via two levels: topic level and feature level. Firstly, we obtained topic-level metrics by identifying topics expressed in tables of contents and calculating topic distributions. Then, we got feature-level results via feature extraction and feature distribution calculation. Finally, we compared depth and breadth metrics and other book assessment metrics. Experimental results reveal that, books’ depth and breadth at two levels are different, and substantial differences between disciplines and book types are obvious. In addition, books’ depth and breadth can provide alternative and supplementary information for assessing multi-dimensional values of books.     

土地流转后农民信息需求结构变动及聚类研究

文章采用田野调查法观察土地流转后农民生活及信息需求,选择区域进行问卷调查,利用SPSS对数据进行分析。结果显示土地流转后农民经济较宽裕,精神却比较空虚。问卷定量化展现了农民在科技信息利用、信息需求类型、信息基础设施、信息获取渠道、休闲方式选择、信息获取程度等方面的内容。聚类分析形成了政策类信息需求及利用、生活类多样化信息需求及利用、农业科技信息需求及利用、网络信息的需求及利用等4个类团。从农业科技信息服务对象的调整与兼顾、公共文化服务教育和精神扶贫功能的发挥、农民文化需求主动性和自觉性的唤醒等方面提出建议。     

构建科技资源共享平台的几个问题

科技资源共享包括信息、设备与数据、人员流动和科研成果等4 个方面的共享。现有的共享形式有知识网 络平台及数据库、科技创新比赛和奖励、科技论坛和会议、地区或国际间科技合作和交流。共享的协调体系由共享主 体和共享规则组成。共享的动力机制是构建科技资源共享体系的核心问题。成功推进共享实现的动力机制的关键在于 合理解决共享的外部性问题和分担风险。管理体制、资金保障、信息渠道和人才管理均会影响共享效率。     

档案公布与知识产权保护微观分析

随着馆藏档案公布数量的迅速增长,档案公布与知识产权保护成为越来越重要的课题。在知识产权中,著作权与档案公布权的关系较为密切。由于档案与作品形式相似,以及档案公布与作品发表的性质相同、方式相似,使得档案公布不仅可能涉及作品的发表权,还可能涉及作品的财产权。幸而,档案与作品在性质和涉及领域,以及档案公布权与作品著作权等方面存在着明显差别,这些差别使得区分档案公布权与作品著作权并对其进行保护成为可能。与著作权不同,专利权和商标权在性质和内容上与档案公布权明显不同,因而,档案的公布一般不会触及专利权和商标权。

Complexity,Uncertainty and Change in News Organizations

ABSTRACT

Media managers and journalists have responded to digitalization over time by implementing online journalism and by converging and de-converging print and online newsrooms. Drawing on complexity and uncertainty theories, this article develops a cycle model, which furthers the understanding of why and how news organizations change. Qualitative and quantitative findings in two European legacy media companies indicate that managers are constantly striving to minimize their own complexity and uncertainty, which, in turn, drives change in news organizations through different stages that are characterized by economization and integration or investment and specialization. More specifically, under lower external and internal complexity and uncertainty, managers are pushing news organizations toward more economization and integration. However, they invest and specialize if either their external or their internal complexity and uncertainty increase. Moreover, the findings reveal the mechanism through which the internal complexity and uncertainty arise, and they show differences depending on the ownership structure of a news organization.     

Resource Sharing in the ICT Era: The Case of Nigerian University Libraries

The paper examines how information and communication technology can be utilized for resource sharing among university libraries in Nigeria. It was based on the study and review of recent library and information science literature on both print and electronic resources. It discusses the meaning of information and communication technology, resource sharing practices, and how information and communication technology facilitates resource sharing. It traces the history of resource sharing among Nigerian libraries. The current state of information and communication technology application and utilization in Nigeria and its university libraries is revealed, with emphasis on university libraries that are located in different zones of the country. The paper examines challenges facing Nigerian University Libraries with respect to information and communication technology application and utilization for resource sharing, as well as to areas of library operations to which information and communication technology can be applied and utilized for resource sharing. It concludes by proffering solutions for viable information and communication technologies–based cooperation among university libraries in Nigeria.     

Evaluation of the KA24 (Knowledge Access 24) service for health- and social-care staff in London and the south-east of England. Part 1: quantitative

AIMS AND OBJECTIVES: This two-part paper aims to identify the main transferable lessons learned from both the quantitative and qualitative evaluations of the Knowledge Access 24 (KA24) service of online databases and selected full-text journals for health and social care staff in London and the south-east of England. The quantitative evaluation analysed usage rates and user registration with the objective of measuring uptake by previously disadvantaged staff, and to inform the subsequent qualitative survey. METHODS: User and usage data were analysed by type of NHS Trust, by type of user, and by what was being used. The evaluation assessed development in user registration and usage of both databases and journals over a 2-year period. Data were aggregated and analysed both monthly and quarterly. RESULTS: Usage levels increased, but uptake in both the mental health and primary care sectors was comparatively slow. Nurses and allied professionals used the service more than doctors. The increase in usage of full-text journals over the usage of databases was marked. CONCLUSIONS: Previously disadvantaged staff used electronic resources. A qualitative survey was needed to identify the main enablers and barriers to uptake.
