Evaluation of the productivity of hospital-based researchers: comparative study between the h-index and the h(fa)-index
Scientometrics - - 2021
The h-index is often used to evaluate researchers and to measure their respective contributions to the scientific community. However, it does not take into account the relative contribution of each author to the articles. We aimed to assess the added value of the h(fa)-index, an index introducing a weighting factor for the first author. This cross-sectional study was conducted in March 2020 in Swi......

Theory and practice of the shifted Lotka function
Scientometrics - Tập 91 - Trang 295-301 - 2011
One of the major drawbacks of the classical Lotka function is that arguments only start from the value 1. However, in many applications one may want to start from the value 0, e.g. when including zero received citations. In this article we consider the shifted Lotka function, which includes the case of zero items. Basic results for the total number of sources, the total number of items and the ave......

Accounting for quality in data integration systems: a completeness-aware integration approach
Scientometrics - Tập 127 - Trang 1465-1490 - 2022
Ensuring the quality of integrated data is undoubtedly one of the main problems of integrated data systems. When focusing on multi-national and historical data integration systems, where the “space” and “time” dimensions play a relevant role, it is very much important to build the integration layer in such a way that the final user accesses a layer that is “by design” as much complete as possible.......
Preprint citation practice in PLOS
Scientometrics - Tập 127 - Trang 6895-6912 - 2022
The role of preprints in the scientific production and their part in citations have been growing over the past 10 years. In this paper we study preprint citations in several different aspects: the progression of preprint citations over time, their relative frequencies in relation to the IMRaD structure of articles, their distributions over time, per preprint database and per PLOS journal. We have ......
Validating indicators of interdisciplinarity: linking bibliometric measures to studies of engineering research labs
Scientometrics - Tập 94 - Trang 439-468 - 2012
This article examines the extent to which specific features of interdisciplinary research are accurately reflected in selected bibliometric measures of scholarly publications over time. To test the validity of these measures, we compare knowledge of research processes and impact based on ethnographic studies of a well-established researcher’s laboratory, together with personal interview data, agai......
A revised measure of standing of journals in stratified networks
Scientometrics - - 1987
A modified index of journal standing in a stratified journal to journal citation network is proposed. The original index, generated through an application of input-output analysis, is used as the first step of an iterative procedure that converges on the new index. This index, an eiginvector of the inverted matrix used in the input-output analysis, has improved validity and better distributional p......
Influence of local and regional publications in the production of public health research papers in Latin America
Scientometrics - Tập 84 - Trang 703-716 - 2010
The study seeks to identify the influence of local and regional publications in the production of public health research papers in the Latin American region. A citation analysis of the papers published in the following three leading journals in the field of public health was conducted: Revista Médica de Chile (Chile) (RMCh); Archivos Latinoamericanos de Nutrición (Venezuela) (ALAN); and Salud Públ......
