Aims: Research on second-generation antipsychotic drugs (SGAs) has experienced great development in last decades. We did a bibliometric study on the scientific publications on SGAs in Japan. Methods: With the EMBASE and MEDLINE databases, we chose papers published from Japan with SGA descriptors. Price’s law and Bradford’s law has been used as bibliometric indicators for quantitating production...
This workshop brings together experts of communities which often have been perceived as different once: bibliometrics / scientometrics / informetrics on the one side and information retrieval on the other. Our motivation as organizers of the workshop started from the observation that main discourses in both fields are different, that communities are only partly overlapping and from the belief t...
Recently, Social Cognitive theory (SCT) has been widely adapted across various disciplines in business and management as well as Information Systems (IS) research. In IS, the use of SCT remains in its early stages. Few bibliometric analyses have been published on mapping theories across previous literature. However, to date factors related to literature review mapping in relation to SCT in IS h...
PURPOSE Corporate scientific activity lies at the heart of the modern academic institution, and yet field-specific estimates of institutional or departmental scholarly productivity are difficult to assess. The authors sought to estimate long-term and current departmental research efforts at residency-sponsoring US radiation oncology departments, using modifications of established bibliometric i...
Modern management of research is increasingly based on quantitative bibliometric indices. Nowdays, the h-index is a major measure of research output that has supplanted all other citation-based indices. In this context, indicators that complement the h-index by evaluating different facets of research achievement are compelling. As an additional bibliometric source that can be easily extracted f...
How to pre-select the most promising candidates for an open position out of several applications? One of the possibilities is to check the personal bibliometric indices of these candidates by looking into appropriate databases. In these databases the number of publications, the total number of citations, the average number of citations per paper and the h-index are easy to find. Thus, it is eas...
Landmark articles from the peer-reviewed literature can be used to teach the fundamental principles of geriatric medicine. Three approaches were used in sequential combination to identify landmark articles as a resource for geriatricians and other healthcare practitioners. Candidate articles were identified first through a literature review and expert opinion survey of geriatric medicine facult...
A bibliometric analysis was applied in this work to evaluate global scientific production of geographic information system (GIS) papers from 1997 to 2006 in any journal of all the subject categories of the Science Citation Index compiled by Institute for Scientific Information (ISI), Philadelphia, USA. ‘GIS’ and ‘geographic information system’ were used as keywords to search parts of titles, ab...
The work is partially a review article and partially a research paper. Problems for evaluation and impact of published scientific works and their authors are discussed at theoretical level. The role of citations in this process is pointed out. Different bibliometric indicators are reviewed in this connection and ways for generation of new bibliometric indices are given. The influence of differe...
A systematic empirical comparison of different approaches for normalizing citation impact indicators
We address the question how citation-based bibliometric indicators can best be normalized to ensure fair comparisons between publications from different scientific fields and different years. In a systematic large-scale empirical analysis, we compare a traditional normalization approach based on a field classification system with three source normalization approaches. We pay special attention t...
