Quo Vadis Clozapine? A Bibliometric Study of 45 Years of Research in International Context

We have carried out a bibliometric study about the international scientific publications on clozapine. We have used the EMBASE and MEDLINE databases, and we applied bibliometric indicators of production, as Price’s Law on the increase of scientific literature. We also calculated the participation index (PI) of the different countries. The bibliometric data have also been correlated with some social and health data from the 12 most productive countries in biomedicine and health sciences. In addition, 5607 original documents dealing with clozapine, published between 1970 and 2013, were downloaded. Our results state non-fulfilment of Price’s Law, with scientific production on clozapine showing linear growth (r = 0.8691, vs. r = 0.8478 after exponential adjustment). Seven of the 12 journals with the highest numbers of publications on clozapine have an Impact Factor > 2. Among the countries generating clozapine research, the most prominent is the USA (PI = 24.32), followed by the UK (PI = 6.27) and Germany (PI = 5.40). The differences among countries on clozapine research are significantly related to economic variables linked to research. The scientific interest in clozapine remains remarkable, although after the application of bibliometric indicators of production, a saturation point is evident in the growth of scientific literature on this topic.     

The use of game theory in regional economics: A quantitative retrospective

One of the most powerful tools within social science in general and economics in particular is game theory. This methodology allows for the formal analysis of the interactions among economic agents and, therefore, it is particularly useful for the study of economic decisions regarding spatial issues. For this reason, a quantitative systematization of the use of this tool on regional economics research is a relevant topic in the agenda concerned with progress in regional science. In this paper we study research in regional economics and provide a quantitative retrospective of the use of game theory in this field. Our main goal is twofold. First, we intend to categorize the contributions in the use of this analytical tool – by main research subjects, by authors' affiliations, by journal, etc. – using a bibliometric approach. Second, by analysing co‐authoring and using social network analysis, we want to test the existence of structures of knowledge upon which distinct co‐authorship emerges. The results of this research provide a framework for analysing the potential use of game theory in regional economics, suggesting new future research directions.     

基于SCI-E的猕猴桃研究文献的计量分析

依据美国科学引文索引数据库扩展版（Science Citation Index Expanded）,对2004-2013年期间SCI-E收录的有关猕猴桃的1 253 篇研究文献,采用文献计量的方法,从论文发表的年份、文献类型与语种、学科领域和来源期刊、核心研究机构、国家或地区分布以及作者等方面对检索结果进行统计分析。结果表明：10 a内SCI猕猴桃研究文献呈逐步增长趋势;研究文献主要以期刊文献、英语文献为主;研究文献的主要学科领域是食品科技和植物科学;载文量最多的期刊是《Postharvest Biology and Technology》;发文量最多的机构为“New Zealand Institute forPlant Food Research Ltd.”;发文较多的国家有新西兰、意大利、中国等;发文最多的作者是塞尔维亚的Gavrovic-Jankulovic和新西兰的Clearwater;最具影响力作者是意大利的Tamburrini。通过该文的分析为我国科研人员了解有关猕猴桃研究动态,确立研究方向,开展科学研究与学术交流提供信息和帮助。
