Comparative analysis between impact factor and h-index for pharmacology and psychiatry journals

Using strictly the same parameters (identical two publication years (2004–2005) and identical one-year citation window (2006)), IF 2006 was compared with h-index 2006 for two samples of “Pharmacology and Pharmacy” and “Psychiatry” journals computed from the ISI Web of Science. For the two samples, the IF and the h-index rankings of the journals are very different. The correlation coefficient between the IF and the h-index is high for Psychiatry but lower for Pharmacology. The linearity test performed between the h-index and

showed the great sensitivity of the model compared with α. The IF and h-index can be completely complementary when evaluating journals of the same scientific discipline.

Recherche et Filtrage de L’information Dans la Bibliotheque Virtuelle

Purpose: The article investigates the evolution of document supply of print serials. Approach: The study is based on data from INIST-CNRS - document supply requests and access to electronic resources - of 95 serials with JCR impact factors in pharmacology. Data were collected from 1992 to 2003. Findings: The results distinguish four groups of serials each with a different evolution of supply requests. Nevertheless, the overall decline from 1999 is a global phenomenon linked to growing access to online journals and there seems little likelihood of a slowdown for the next few years. Originality: This is the first of three articles on a longitudinal study over 12 years on different aspects of the relationship between document supply and impact factor (citations) in pharmacology, a scientific domain with a high use of scientific information.

Purpose: The article investigates the customers for the document supply of print serials. Approach: The study is based on data from INIST-CNRS for document supply requests in pharmacology. Data were collected from 1998 to 2005 (10,000+ customer accounts with 4.6m orders). Findings: The article provides information about the distribution of orders per customer type, about the geographical origin of customers, about the ordering trends among pharmaceutical customers and of pharmaceutical journals. Originality: This is the last of three articles on a longitudinal study over 13 years on different aspects of the relationship between document supply and impact factor (citations) in pharmacology, a scientific domain with a high use of scientific information.

Rédaction des adresses sur les publications: Un manque de rigueur défavorable aux universités françaises dans les classements internationaux

Purpose: The article investigates the correlation between citations and the document supply of print serials. Approach: The study is based on data from INIST-CNRS for document supply requests and from ISI for citations from 89 serials with JCR impact factors in pharmacology. Data were collected from 1992 to 2004. Findings: The results distinguish four groups of serials with different relationships between document supply requests and citations. The characteristics of the serials of the four groups are described (year of creation, price, etc). The evolution of the correlation between document supply and citations is analysed. Originality: This is the second of three articles on a longitudinal study over 13 years on different aspects of the relationship between document supply and impact factor (citations) in pharmacology, a scientific domain with a high use of scientific information.

European pharmaceutical journals: Relationship between demand and indexation - the example of the main French document supplier

The study aims to investigate the relationships between consumption of e-journals distributed by Elsevier ScienceDirect platform, publication (articles) and impact (citations) in a sample of 13 French universities, from 2003 to 2009. It adopts a value perspective as it questions whether or not publication activity and impact are some kind of return led by consumption. A bibliometric approach was used to explore the relations between these three variables. The analysis developed indicators inspired by the mathematical h-Index technique. Results show that the relation between consumption, publication and citations depends on the discipline’s profile, the intensity of research and the size of each institution. Moreover, although relations have been observed between the three variables, it is not possible to determine which variable comes first to explain the phenomena. The study concludes by showing strong correlations, which nevertheless do not lead to clear causal relations. The article provide practical implication for academic library managers who want to show the added value of their electronic e-journals collections can replicate the study approach. Also for policy makers who want to take into account e-journals usage as an informative tool to predict the importance of publication activity.

Analyse comparative du facteur d'impact et du h-index pour les journaux de pharmacologie

L’Internet connait depuis les annees 90 un developpement impressionnant. La messagerie individuelle et de groupe (Listes et News) est devenue le premier outil de communication informelle des chercheurs. Les services de publication tels Gopher puis W3 permettent de diffuser de maniere rapide, massive et a peu de frais l’information produite dans les universites, les laboratoires de recherche etc..
