Theory and practice of the shifted Lotka functionScientometrics - Tập 91 - Trang 295-301 - 2011
Leo Egghe, Ronald Rousseau
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

Accounting for quality in data integration systems: a completeness-aware integration approachScientometrics - Tập 127 - Trang 1465-1490 - 2022
Cinzia Daraio, Simone Di Leo, Monica Scannapieco
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.... hiện toàn bộ
Preprint citation practice in PLOSScientometrics - Tập 127 - Trang 6895-6912 - 2022
Marc Bertin, Iana Atanassova
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 ... hiện toàn bộ
Validating indicators of interdisciplinarity: linking bibliometric measures to studies of engineering research labsScientometrics - Tập 94 - Trang 439-468 - 2012
David Roessner, Alan L. Porter, Nancy J. Nersessian, Stephen Carley
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,

A revised measure of standing of journals in stratified networksScientometrics - - 1987
P. Doreian
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... hiện toàn bộ
Influence of local and regional publications in the production of public health research papers in Latin AmericaScientometrics - Tập 84 - Trang 703-716 - 2010
C. A. Macías-Chapula
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... hiện toàn bộ
