A form of normalisation is presented for the evaluation of citation data on multidisciplinary research. This method is based on the existing classification according to the publishing journals and not on the classification of output according to ISI subject categories. A publication profile is created for each institution to be investigated. This profile accounts for the weight of publications ...

We study the distributions of citations received by a single publication within several disciplines, spanning broad areas of science. We show that the probability that an article is cited c times has large variations between different disciplines, but all distributions are rescaled on a universal curve when the relative indicator c(f) = c/c(0) is considered, where c(0) is the average number of ...

Introduction In order to evaluate the impact of publications in terms of citation counts recently percentile-based bibliometric indicators have gained more and more attention (Bornmann, Leydesdorff, ...

RATIONALE The American Recovery and Reinvestment Act (ARRA) allowed National Heart, Lung, and Blood Institute to fund R01 grants that fared less well on peer review than those funded by meeting a payline threshold. It is not clear whether the sudden availability of additional funding enabled research of similar or lesser citation impact than already funded work. OBJECTIVE To compare the citat...
