Journal impact factors (IFs), a measure of citation frequency, are published annually in Journal Citation Reports (JCR). Journal IFs, although controversial because of the uses to which they have been put in academic arenas, remain a metric about which nurses should be informed. This paper discusses key issues in the controversy, explains how IFs are computed, and presents historical and 2009 I...

The possibilities of using the Arts & Humanities Citation Index (A&HCI) for journal mapping have not been sufficiently recognized because of the absence of a Journal Citations Report (JCR) for this database. A quasi-JCR for the A&HCI (2008) was constructed from the data contained in the Web-of-Science and is used for the evaluation of two journals as examples: Leonardo and Art Journal. The maps...

Citation analysis is increasingly used to measure scientific i f mpact o Journals (impact factor) Authors Institutions JCR impact factors limited to journals Much computer science research is published only in conferences Need to consider citations from / to (refereed) conference publications Citation analysis is a huge data integration problem Need to automate as much as possible with good dat...

BACKGROUND The impact factors of scientific journals are interesting but not unproblematic. It is speculated that the number of journals in which citations can be made correlates with the impact factors in any given speciality. METHODS Using the Journal Citation Report (JCR) for 1997, a bibliometric analysis was made to assess the correlation between the number of journals available in differ...

In the corpulent James C. Russell corpulent (JCR:LA-cp) rat, hyperinsulinemia leads to induction of lipogenic enzymes via enhanced expression of sterol-regulatory-binding protein (SREBP)-1c. This results in increased hepatic lipid production and hypertriglyceridemia. Information regarding down-regulation of SREBP-1c and lipogenic enzymes by dietary fatty acids in this model is limited. We there...
