I is surprising that the prevailing performance taxonomy for scientists (star versus nonstar) focuses only on individual output and ignores social behavior, because innovation is often characterized as a communal process. To develop a deeper understanding of the mechanisms by which scientists influence the productivity of others, I expand the traditional taxonomy of scientists that focuses sole...

Efficiency and evaluation is one of the main and most important demands of organizations, companies and institutions. As these organizations deal with a large amount of data, therefore, it is necessary to evaluate them on the basis of scientific methods to improve their efficiency. Data envelopment analysis is a suitable method for measuring the efficiency and performance of organizations. This...

IBM PC/XT/AT and compatibles users of the popular graphics program Sigma-plot by Jandel Scientific (reviewed in Yale J Biol Med 61:174-175, 1988), who have recently acquired an HP Laserjet printer, may be surprised and disappointed. This program, which has performed so well for so many users of dot matrix printers and plotters, is abysmally slow when using a laser printer (output times in exces...

OBJECTIVE To evaluate by the h index the scientific output of researchers from the University of Guadalajara who belong to the Sistema Nacional de Investigadores in the field of Medicine and Health Sciences. METHODS Researchers from the University of Guadalajara were selected from the Active SNI Researchers 2013 file. The scientific output of researchers in the fields of Medicine/Health Scien...

The aim of this study was to evaluate surgical scientific publication in relation to the 1991-1995 war in Croatia, based on the articles indexed in Medline database that were published in 1980-2005 period. The number of articles was extracted from PubMed and analysed with trend analysis, which is preferred analytic approach over calculation of crude publication rates. The results indicate spora...

The performance-oriented allocation of funds and excellence initiatives is now widespread in science and research and has led to questions concerning fair national and international bibliometric benchmarks for comparing scientific institutions becoming a hot topic. As publication and citation practices strongly depend on scientific fields, field normalisation is widely recognised as necessary f...

In Brazil, a system was created on 1951 with the objectives of improving technology and innovation and strengthening scientific research.2,3 Similar to postgraduate doctorate programs in developed countries, postgraduate programs with broader and more in-depth scientific research objectives have been developed in Brazil.4 In fact, a linear relationship has been demonstrated between the number o...

The present paper proposes the idea of formulating a new author-level citation metrics, quantifying individual’s scientific output, which uses concept intuitionistic fuzzy sets. This metrics gives more visibility to proportion direct self-citations and hidden (co-author or collaborative) in form an pair. Examples are given retrieving necessary information from Scopus, one largest databases peer...
