The paper is concerned with analysing what makes a great journal great in the sciences, based on quantifiable Research Assessment
Measures (RAM). Alternative RAM are discussed, with an emphasis on the Thomson Reuters ISI Web of Science database (hereafter
ISI). Various ISI RAM that are calculated annually or updated daily are defined and analysed, including the classic 2-year
impact factor (2YIF), 5-year impact factor (5YIF), Immediacy (or 0-year impact factor (0YIF)), Eigenfactor, Article Influence,
C3PO (Citation Performance Per Paper Online), h-index, Zinfluence, PI-BETA (Papers Ignored—By Even The Authors), Impact Factor
Inflation (IFI), and three new RAM, namely Historical Self-citation Threshold Approval Rating (H-STAR), 2 Year Self-citation
Threshold Approval Rating (2Y-STAR), and Cited Article Influence (CAI). The RAM data are analysed for the 6 most highly cited
journals in 20 highly-varied and well-known ISI categories in the sciences, where the journals are chosen on the basis of
2YIF. The application to these 20 ISI categories could be used as a template for other ISI categories in the sciences and
social sciences, and as a benchmark for newer journals in a range of ISI disciplines. In addition to evaluating the 6 most
highly cited journals in each of 20 ISI categories, the paper also highlights the similarities and differences in alternative
RAM, finds that several RAM capture similar performance characteristics for the most highly cited scientific journals, determines
that PI-BETA is not highly correlated with the other RAM, and hence conveys additional information regarding research performance.
In order to provide a meta analysis summary of the RAM, which are predominantly ratios, harmonic mean rankings are presented
of the 13 RAM for the 6 most highly cited journals in each of the 20 ISI categories. It is shown that emphasizing THE impact
factor, specifically the 2-year impact factor, of a journal to the exclusion of other informative RAM can lead to a distorted
evaluation of journal performance and influence on different disciplines, especially in view of inflated journal self citations. 相似文献
