Towards all-author co-citation analysis   总被引：3，自引：0，他引：3  

Dangzhi Zhao   《Information processing & management》2006,42(6):1578

The present study examines one of the fundamental aspects of author co-citation analysis (ACA): the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting: on the one hand, the traditional type that only counts the first one among a cited work’s authors, and on the other hand, a simplified approach to all-author co-citation counting that takes into account the first five authors of a cited work. Results indicate that the picture produced through this simplified all-author co-citation counting contains author groups that are more coherent, and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed. Variations of counting more than first authors are compared.  相似文献   

Bridging the Divide: Building Asia-Pacific Capacity for Effective Reforms     

Rohan Samarajiva  Sujata Gamage 《The Information Society》2007,23(2):109-117

This article spotlights the need to develop capacity for ICT policy and regulation within developing countries. It argues that capacity should to be developed among all stakeholders, not solely within government agencies, because that would enable effective participation by many players in the regulatory process. The resulting participatory regulatory process will in turn increase accountability and procedural legitimacy. The article examines different approaches to developing in situ expertise, especially just-in-time learning and open-source research.  相似文献   

浅谈礼貌原则对跨文化交际的影响     

周宇岚 《中国科技信息》2007,(16):153-154

跨文化交际中有许多潜在的障碍。从语用学的角度看．遵循礼貌原则是有效推进跨文化交际的重要手段。然而，札貌原则受到许多因素的制约．具有灵活性和多样性的特点。我们必须研究这些特点，才能使跨文化交际更好的进行。本文从比较中西文化对礼貌原则的评判标准和实施方略的不同入手，详细论述了中西文化中谦逊准别与赞同准则，集体主义与个人主义以及语境对执行礼貌原则的不同影响。阐述了礼貌原则对跨文化交际的指导意义。通过论述，在文章结尾得出结论．文化认同是跨文化交际的语用原则，是执行礼貌原则的前提。只有寻求文化认同，才能更好地利用礼貌原则为跨文化交际的顺利进行服务。  相似文献   

构建面向知识经济的国家科技传播体系   总被引：16，自引：1，他引：16  

翟杰全 《科研管理》2001,22(1):8-13,123

科技传播在20世纪获得了巨大的发展，但也遇到了一系列严重的困难，为促进科技传播事业的发展，支持社会的知识创新和知识应用，需要在国家宏观层面上对科技传播进行有效地管理和规划，建立国家科技传播体系，本文讨论了国家科技传播体系的基本内涵及其在社会（国家）创新体系中的功能，认为在建立国家科技传播体系中，应加强组织平产业平台、技术平台、相关政策法规体系等支撑平台的建设。  相似文献

科技奖励对社会创新的影响机理——基于广东的探索性案例分析     

郑茜 《科技管理研究》2020,40(24):19-25

对科技奖励作用于社会创新的机理加以研究，认为承认是科技奖励的本质特征，科技奖励以“动机+资源+环境”的模式推动社会创新进程和成果转化：通过承认机制激发科研人员的需求；通过激励机制强化科研人员的创新动机；通过导向机制引导优势资源向重点发展技术领域、产业方向聚集；通过竞争机制筛选优秀科研成果和人才，营造良好的社会创新环境。而在这种模式下取得的经济效益又用于加大科技奖励投入，循环往复地推动社会创新不断发展。以广东省科学技术奖为例研究其对社会创新的作用机制，认为其主要通过控制奖励数量、提高奖金额度、调整奖项结构、提升奖励质量等方式发挥科技奖励的承认、激励导向和竞争作用。在此基础上分析广东省科技奖励体系存在的问题，提出发挥民间力量设奖、规范奖后派生待遇、提高个人奖项权重、加大对青年科学家支持力度等对策建议。  相似文献   

Understanding the emergence and deployment of “nano” S&T     

Barry Bozeman  Philippe Laredo 《Research Policy》2007,36(6):807-812

As an introduction to the special issue on “emerging nanotechnologies”, this paper puts in perspective contemporary debates and challenges about nanotechnology. It presents an overview of diverse analyses and expectations about this presumably revolutionary set of technological, scientific and industrial developments. Three main lines of argument can then be delineated: first of all, the degree of cumulativeness of science and technologies and the respective roles of newcomers and incumbents in the industrial dynamics; second the knowledge dynamics in nanotechnologies, especially the linkages by science and technology and third the role of institutions (network, geographic agglomeration and job market). It finally discusses methodologies to delineate the field of nanotechnologies and to collect data.  相似文献

战略环境影响评价的理性范式思考   总被引：2，自引：0，他引：2  

侯小阁  栾胜基 《科学学研究》2007,25(2):269-273

SEA是以提高战略决策质量为目标的技术辅助工具,以标准化的程序方法模式来进行决策的环境影响识别、预测和评价,以物理环境的技术研究为侧重。然而,因为战略本身的复杂性和政治特征,有学者认为,SEA应该更侧重于提供不同利益团体共识达成的平台,在形式上具备对决策背景的可适应性和灵活性,不应该以标准化来僵化自身。有关两种模式的争论与目前学术界对工具理性、价值理性、非理性和交往理性的争论不无渊源。借用理性范式这个视角对SEA的两种模式进行深层思考,分析两种模式的各自长短之处,寻找互补的可能性,期望能够对SEA的发展提供可供借鉴的观点。  相似文献
