国家、城市和组织的期刊组合分析：地图和比较
Journal Portfolio Analysis for Countries, Cities, and Organizations: Maps and Comparisons
摘要：
使用Web-of-Science数据，就期刊覆盖率而言的投资组合分析可以投射到国家、城市、大学和公司等分析单位的基本地图上。研究中的分析单位可以在10，000多种期刊中进行统计比较。投资组合的跨学科性是使用Rao-Stirling多样性或Zhang et al.的（在新闻中）改进措施2D 3。在国家一级，我们发现区域差异（例如，拉丁美洲或亚洲国家），但也是发达国家和欠发达国家之间的一个重大鸿沟。以色列和以色列城市在多样性方面优于其他国家和城市。大学似乎是具体相关的企业时，一些这些单位进行了探索性的比较。该工具相对简单和直接，并且可以将应用程序推广到从WoS检索的任何文档集。进一步的说明可在http://www.leydesdorff.net/portfolio网站上查阅。
英文摘要：
Using Web-of-Science data, portfolio analysis in terms of journal coverage can be projected on a base map for units of analysis such as countries, cities, universities, and firms. The units of analysis under study can be compared statistically across the 10,000+ journals. The interdisciplinarity of the portfolios is measured using Rao-Stirling diversity or Zhang et al.'s (in press) improved measure 2D3. At the country level we find regional differentiation (e.g., Latin-American or Asian countries), but also a major divide between advanced and less-developed countries. Israel and Israeli cities outperform other nations and cities in terms of diversity. Universities appear to be specifically related to firms when a number of these units are exploratively compared. The instrument is relatively simple and straightforward, and one can generalize the application to any document set retrieved from WoS.
