“…Schubert and Glanzel (2007) Thus, the data suggest that the h-index is highly correlated with a nonlinear function of the number of publications and the impact factor, such that the RAM are related. Bornmann et al (2008) compare the h-index and eight important variations thereof for purposes of evaluating research output and the journal impact factor.…”

“…Schubert and Glanzel (2007) suggested that the h-index is highly correlated with the impact factor, and Bornmann et al (2008) compared nine important variations of the h-index to evaluate research output and the journal impact factor. In Table 3, the h-index is shown to have correlations in excess of 0.5 with six other RAM (including 0.541 and 0.591 with 2YIF and 5YIF, respectively), which shows there is indeed overlap among the different RAM, especially citation rates.…”

The 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.

“…The H-index is a single bibliometric indicator that combines measures of productivity and impact into one. Hirsch argued that this combination reflects the impact of a publication on the corresponding scientific community (Braun et al, 2006;Schubert & Glänzel, 2007). H-index retrieved by citation indexes (Scopus, Google scholar, and Web of Science) is used to measure the scientific performance and the research impact studies based on the number of publications and citations of a scientist.…”

Publication productivity, as measured by the number of papers, has been regarded as one of the main indicators of reputation of countries and institutions. Nevertheless, the relationship among research publications, economic growth and World Wide Web in ASEAN countries is still unclear. The main intention of this study was to identify publication productivity among ASEAN and the world's top ten countries in the last 16 years (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011). This study also aimed at finding the relationship among publication, gross domestic product (GDP) and internet usage. Furthermore, the publication trend in the 10 first Malaysian universities was evaluated for the same periods. Scopus database was used to find the overall documents, overall citations, citations per document and international collaboration from 1996 to 2011 for each country. The World Bank database (World Data Bank) was used to collect the data for GDP and the number of internet users. Moreover, to evaluate 10 top Malaysian universities, the number of published articles, conferences, reviews, and letters for the same periods was collected. The results of this study showed significant differences among ASEAN and top 10 countries regarding publication productivity. Moreover, a positive and significant relationship was observed between indices, GDP and internet usage for these countries. Surprisingly, international collaboration had a significant and negative relationship with economic growth. Malaysia had fewer citations per document (7.64) and international collaboration (36.9%) among ASEAN countries. In conclusion, international collaboration between academic institutes and researchers is influenced by economic growth and access to internet in the countries. Furthermore, publication trends in ASEAN countries are promising. However, policy makers and science managers should try to find different ways to increase the quality of the research publication and to raise citation per document.

“…Recently Gla¨nzel (2008) has alerted the informetric community to new applications of rank-frequency and extreme-value (or tail properties of Pareto-type distributions) statistics related to the h-index. Furthermore, the h-index, initially intended for the assessment of individual academics, has been extended from micro-level evaluation of individuals to macro-level evaluation of journals (Braun et al 2005(Braun et al , 2006Schubert and Glänzel 2007;Vanclay 2008), research groups (Van Raan 2006) and institutions (Arencibia-Jorge et al 2008;Molinari and Molinari 2008;Pires da Luz et al 2008). A recent application of the h-index to an even further micro-level was made by Schubert (2009) to assess single highly cited publications.…”

Journal Impact Factors for evaluating scientific performance: use of h-like indicators

This article introduces the Impact Factor squared or IF²-index, an h-like indicator of research performance. This indicator reflects the degree to which large entities such as countries and/or their states participate in top-level research in a field or subfield. The IF²-index uses the Journal Impact Factor (JIF) of research publications instead of the number of citations. This concept is applied to other h-type indexes and their results compared to the IF²-index. These JIF-based indexes are then used to assess the overall performance of cancer research in Australia and its states over 8 years from 1999 to 2006. The IF²-index has three advantages when evaluating larger research units: firstly, it provides a stable value that does not change over time, reflecting the degree to which a research unit participated in top-level research in a given year; secondly, it can be calculated closely approximating the publication date of yearly datasets; and finally, it provides an additional dimension when a full article-based citation analysis is not feasible. As the index reflects the degree of participation in top-level research it may favor larger units when units of different sizes are compared.
