Methods: PubMed was searched using "safety management" for the literature on nursing safety management. BICOMB 2.0 and SPSS 20.0 software were used to analyze high-frequency keywords and conduct co-word clustering analysis. Results: We searched for totally 2353 articles related to our topic and extracted 19 high-frequency keywords (27.50%). Five research focuses were concluded, including: study on nursing safety culture; team work to promote nursing safety; practice of nursing safety management; workplace violence against nursing staffs; nursing safety and quality evaluation standard. Conclusion: Analysis of the hotspots of nursing safety management in the past 10 years will contribute to understanding the research emphases and trend of development, and provide reference for the study and practice of nursing safety management.展开更多

Information visualization and knowledge domain visualization techniques were adopted to determine how the study of scientific collaboration has evolved. A total of 1,455 articles on scientific cooperation published between 1993 and 2007 were retrieved from the SCI, SSCI and A&HCI databases with a topic search of scientific collaboration or scientific cooperation for the analysis. By using CiteSpace, the knowledge bases, research foci, and research fronts in the field of scientific collaboration were studied. The results indicated that research fronts and research foci are highly consistent in terms of the concept, origin, measurement, and theory of scientific collaboration. It also revealed that research fronts included scientific collaboration networks, international scientific collaboration, social network analysis and techniques, and applications of bibliometrical indicators, webmetrics, and health care related areas.展开更多
基于Web of Science,利用社会网络分析等方法对国外社交网络(SNS)研究文献进行分析。结果表明:(1)国外社交网络研究一直关注的重点是:模型、身份、朋友、交流和互联网使用;(2)社交网络研究的热点领域是:用户接受、web2.0、企业2.0、社...基于Web of Science,利用社会网络分析等方法对国外社交网络(SNS)研究文献进行分析。结果表明:(1)国外社交网络研究一直关注的重点是:模型、身份、朋友、交流和互联网使用;(2)社交网络研究的热点领域是:用户接受、web2.0、企业2.0、社会资本、自尊、性别、隐私、社会网络分析、用户行为、以计算机为媒介的传播、自我呈现与自我表露、社交网络平台(Facebook、MySpace、Twitter)、社会化媒体等;(3)社交网络研究的前沿领域呈现出细分趋势,主要集中在健康、青少年与儿童、知识管理,以及社会化电子商务等方面。展开更多
确定一定数量的高频词是识别研究热点的基础性工作,但是目前对于如何确定高低词频的分界点还缺乏客观的、行之有效的方法。本研究以2002~2011年收录入Web of Science SCI中934篇科学计量相关文献为语料,分析了齐普夫定律中的常数变...确定一定数量的高频词是识别研究热点的基础性工作,但是目前对于如何确定高低词频的分界点还缺乏客观的、行之有效的方法。本研究以2002~2011年收录入Web of Science SCI中934篇科学计量相关文献为语料,分析了齐普夫定律中的常数变化规律,进而基于统计分析创建了一种确定语料中高低词频分界点的新方法。通过比较分析发现,相对于已有的方法,本方法在识别高频词方面具有数量和稳定性两方面的双重优势。应用该方法识别科学计量学的研究热点,发现10年来科学计量研究领域已形成一系列成熟、稳定的研究议题,如引文分析、期刊影响因子、产出评价等。同时这一领域也处于不断发展之中,引文分析方法的成熟和h指数等新型研究议题的兴起使这一领域的研究正在走向深化。展开更多
基于web of science中2001-2011年电子商务研究文献,利用Netdraw绘制国际电子商务研究的主题演化图谱。研究发现:11年间的研究主题演变实现了从实践技术基础向理论总结精炼的深化,从交易平台建设到产业规模化研究的转移,从商务管理模式...基于web of science中2001-2011年电子商务研究文献,利用Netdraw绘制国际电子商务研究的主题演化图谱。研究发现:11年间的研究主题演变实现了从实践技术基础向理论总结精炼的深化,从交易平台建设到产业规模化研究的转移,从商务管理模式向消费者行为研究的推进;技术支持、商业管理、电子商务模式、网络基础建设和消费者行为研究是11年来的研究热点主题。总结了国际电子商务研究的特征,并对未来研究进行了展望。展开更多
