图书馆业态的变化与发展趋势

图书馆业态是指图书馆事业为满足不同读者需求而进行相应要素组合所形成的运行形态。目前,信息资源正由模拟形态进入数字形态、文献结构由线性到多维、读者更多地依赖网络获取信息、书刊涨价、其他信息行业的竞争等因素,正在促进图书馆业态的变化。这种变化的趋势主要表现在图书馆日益嵌入社会、逐渐成为读者中心,实现数字化获取、资源整合、馆际联盟、权威服务,以及回归其教育和文化价值。参考文献63。     

网络科技论文专家评价模型研究

网络科技论文专家评价模型定量指标有:被访次数、被引次数、被下载和打印次数、被转载次数、引文数量、链接数量和相关成果获奖次数等;定性指标有:权威性、准确性、新颖性、全面性和便利性等。可按一定的规范流程对专家评价模型指标进行量化处理。应按确定评价对象、确定专家评价团、确定评分标准、进行数据分析、写评价报告和收集反馈信息的流程实施专家评价模型。表1。参考文献3。     

国家科技图书文献中心预订外文科技文献资源分析与评价

采用文献计量学和信息分析等方法对国家科技图书文献中心预订外文科技文献资源进行分析和评价。主要评价指标包括:是否被权威数据库收录、是否世界著名出版机构出版、被国外著名图书馆收藏情况、SCI影响因子值及SCI被引用次数、国内缺藏情况、是否属于收藏薄弱学科的期刊、被专家学者推荐情况。通过整体与分散评价,最终选出基本符合主要指标的期刊和会议文献作为新增文献资源的备选源。表3。参考文献7。     

知识管理活动创新性研究之协同知识管理

协同知识管理是指:连接组织内部各个部门或人员,整合组织内部知识资源,协调组织内部各类系统,使其长期合作,促进知识管理目标的实现,使知识管理的各个环节都能以整体效益最大化的方式运作。协同知识管理模型有3个要素:协同工作环境,技术支持与资金保障,人际互动与企业文化。图1。参考文献6。

A collaborative network for first responders: Lessons from the CapWIN case

It is increasingly important for government agencies to collaborate across jurisdictional and functional boundaries. Interorganizational systems supporting interagency collaboration must accommodate a wide range of factors from the external environment and participating organizations as part of their design and operation. This paper presents the findings from a case study of CapWIN, a collaborative network created to enable first responders to share information across jurisdictional and functional boundaries as they work together during emergencies and other critical events. The study examines how aspects of the external environment and the agency context impeded or facilitated the CapWIN collaborative network and the interorganizational system (IOS) that supports it. We identify factors affecting information sharing and collaborative processes, and describe how these factors interact to enable and constrain an IOS. The paper concludes with suggestions for further research on the interplay of environmental, organizational, and technical aspects of interagency collaboration networks as they evolve over time.     

Dimensions of variability in embedded operating systems

Design, implementation, and re-engineering of operating systems are still an ambitious undertaking. Despite, or even because, of the long history of theory and practice in this field, adapting existing systems to environments of different conditions and requirements as originally specified or assumed, in terms of functional and/or non-functional respects, is anything but simple. Especially this is true for the embedded systems domain which, on the one hand, calls for highly specialized and application-aware system abstractions and, on the other hand, cares a great deal for easily reusable implementations of these abstractions. The latter aspect becomes more and more important as embedded systems technology is faced with an innovation cycle decreasing in length. Software for embedded systems needs to be designed for variability, and this is in particular true for the operating systems of this domain. The paper discusses dimensions of variability that need to be considered in the development of embedded operating systems and presents approaches that aid construction and maintenance of evolutionary operating systems.
