这项分析基于国际数据库《科学引文索引》和西班牙数据库ICYT。在1994-2001年期间，共为分析的333名常设科学家确定了3302篇SCI和1183篇ICYT出版物。通过不同的指标来研究科学家的科学业绩，这些指标涉及：活动(SCI和ICYT生产率)、预期影响(出版物的平均影响、顶级期刊中文献的百分比)、观察到的影响(每篇文献被引用的次数、高被引文量)和出版习惯。只有3%的科学家在此期间没有展示任何出版物。可以观察到国际生产率的提高，而国家生产率往往随着时间的推移而下降。研究型教授(CSIC的最高专业类别)表现出比其他类别更高的生产率和观察到的影响。然而，发现了一群来自不同专业类别的科学家，他们对高质量的期刊采取了有选择的出版策略，并获得了大量引用。概述了在微观一级获取指标的主要优点和局限性。
This analysis is based on the international database Science Citation Index and the Spanish database ICYT combined. A total of 3,302 SCI and 1,183 ICYT publications were identified during 1994-2001 for the 333 permanent scientists analysed. The scientific performance of scientists was studied through different indicators related to: activity (SCI and ICYT productivity), expected impact (average impact of publications, percentage of documents in top journals), observed impact (number of citations per document, number of highly cited papers) and publication habits. Only 3% of the scientists did not show any publication in the period. An increase in international productivity is observed while national productivity tends to decrease over time. Research professors (the highest professional category at CSIC) show higher productivity and observed impact than the remaining categories. However, a collective of scientists from different professional categories with a selective publication strategy towards high-quality journals and rewarded with a high number of citations is identified. Main advantages and limitations in obtaining indicators at the micro-level are outlined.
