Design/methodology/approach: Records retrieved from Web of Science were submitted to author co-citation analysis(ACA) following a longitudinal perspective as of the following time slices: 1986–1996, 1997–2006, and 2007–2015. The top 10% of most cited first authors by sub-periods were mapped in bibliometric networks in order to interpret the communities formed and their relationships.Findings: KM is a homogeneous field as indicated by networks results. Nine classical authors are identified since they are highly co-cited in each sub-period, highlighting Ikujiro Nonaka as the most influential authors in the field. The most significant communities in KM are devoted to strategic management, KM foundations, organisational learning and behaviour, and organisational theories. Major trends in the evolution of the intellectual structure of KM evidence a technological influence in 1986–1996, a strategic influence in 1997–2006, and finally a sociological influence in 2007–2015.Research limitations: Describing a field from a single database can offer biases in terms of output coverage. Likewise, the conference proceedings and books were not used and the analysis was only based on first authors. However, the results obtained can be very useful to understand the evolution of KM research.Practical implications: These results might be useful for managers and academicians to understand the evolution of KM field and to(re)define research activities and organisational projects.Originality/value: The novelty of this paper lies in considering ACA as a bibliometric technique to study KM research. In addition, our investigation has a wider time coverage than earlier articles.展开更多

We investigated the trends in publication of articles under the topic ＂neurogenic bladder＂ using bibliometric analysis. Articles on neurogenic bladder, published between 1995 and 2014, were retrieved from the ISI Web of Science citation database. We analyzed the search results for authors, countries, institutions, journals, and top-cited papers. A total of 1,904 articles were re- trieved. There was a small increase in the number of articles on neurogenic bladder from 1995 （n = 43） to 2014 （n = 117）. The USA was the leading country in the total number of articles （n = 598）. However, the number of publications from China has rapidly increased, and China was ranked second in 2014. Emmanuel Chartier-Kastler （n = 65） was the most productive author, and University of Paris VI （Paris 6） （n = 61） was the most productive institution. The Journal of Urology published the greatest number of artides on this topic （n = 285）. Articles on neurogenic bladder were often published in a professional journal under the category Urology ＆ Nephrology, Neurosciences ＆ Neurology, or Rehabilitation. Visualization analysis based on co-citation networks was conducted using CiteSpace III. Visualization analysis revealed that the hot spots in neurogenic bladder were botulinum toxin-A, prazosin, bethanechol, and afferent pathways. These findings provide new insight into the publication trends and hot spots in neurogenic bladder.展开更多

文摘目的基于药物治疗管理的研究,通过图表、网络图的视觉化手段,直观地呈现相关研究热点、发展趋势等,以深度挖掘其关键问题和未来研究方向。方法利用CiteSpace软件分析来自中国知网、PubMed、Web of science 2013年1月至2024年4月的文献。通过发文趋势分析、共现分析、聚类分析以及突现(Burst)分析,绘制相关图谱并进行结果解析。结果药物治疗管理领域的发文数量呈上升趋势,但作者和机构的合作网络分散,表明我国在该领域的合作不够紧密。关键词如“药学服务”“药物治疗”“临床药师”和“药师”突出了该领域的研究热点,涵盖了服务、治疗过程、药师角色等多个方面,反映了其内涵和发展方向。结论“药学门诊”和“家庭药师”成为热门词汇,反映出药学服务的普及和深入,药师的责任也在增强。我国药物治疗管理尚处于探索阶段,需要进一步明确和改进研究和发展方向。
文摘目的:针对药物流行病学在临床药学中的研究领域开展可视化引文分析。方法:借助可视化引文分析工具Hist Cite,以Web of Science核心合集的科学引文索引数据库扩展版为数据源,综合运用文献计量分析、引文分析和可视化技术,分析药物流行病学在临床药学研究文献中的核心期刊和当前研究的热点,并用可视化方法展示临床药学研究的发展历史。结果:得到了Pharmacoepidemiology and Drug Safety等10种药物流行病学在临床药学领域的核心期刊,确定了药物流行病学研究的热门研究主题,并用引文编年图直观地展示药物流行病学在临床药学研究领域的发展历史和阶段。结论:药物流行病学在临床药学研究领域发展迅速,Hist Cite能够快速、直观地展现药物流行病学在临床药学研究领域的发展轨迹。
