Provedor de dados: 5
Autores: Rumin, Judith; Nicolau, Elodie; Gonçalves De Oliveira Junior, Raimundo; Fuentes-grünewald, Claudio; Flynn, Kevin J; Picot, Laurent.
A bibliographic database of scientific papers published by authors affiliated worldwide, especially focused in Europe and in the European Atlantic Area, and containing the keywords “microalga(e)” or “phytoplankton” was built. A corpus of 79,020 publications was obtained and analyzed using the Orbit Intellixir software to highlight the evolution of the research domain. Publication rates from 1960 to 2019, organization of the research, collaboration networks between countries and organizations, emerging and fading research concepts, major studied species, and associated concepts, as well as journals publishing microalgae research were considered. As a result, of the 79,020 papers published worldwide, 26,137 included authors from Europe (33% of world...

The h-index in Academic Morphology
Provedor de dados: 77
Autores: Cantín,Mario; Muñoz,M; Roa,Ignacio.
The h-index is an objective and easily calculable measure that can be used to evaluate both the relevance and amount of scientific contributions of an individual author and field. The aim was to examine how the h-index of academic morphologists in Chile relates with academic rank. A descriptive and correlational study was design. We accessed the Chilean Society of Anatomy professor list in January of 2015, for analysis of academic morphologists' h-indexes using the Scopus database, and data was organized by academic rank. Also, m-Quotient was calculated. Institutional productivity was measured, and institutions were ranked on the basis of cumulative h-index, m-Quotient and the total number of publications and citations. For all morphologists analyzed, the...

What is Published in Human Morphology?: Types of Designs and Levels of Evidence
Provedor de dados: 77
Autores: Suazo Galdames,Iván; Manterola D,Carlos.
Evidence-based medicine (EBM) employs the best available evidence in a particular time and context to solve specific clinical problems. This method of practicing medicine has been adopted by most of the disciplines involved in medical training; however, morphology appears to remain beyond this paradigm. The first step in evidence-based practice based on morphology is to recognize the types of studies being conducted with regard to morphology, followed by the assessment of the level of evidence that they provide, which is the purpose of this study. We designed a bibliometric study, in which journals in the Master Journal List of Thomson Reuters, selected using the keywords "Morphology" or "Anatomy," available between 2007 and 2008, with access to full text...

Neotropical Ichthyology: trajectory and bibliometric index (2003 - 2010)
Provedor de dados: 83
Autores: Stumpf,Ida Regina Chitto; Vanz,Samile Andrea de Souza; Gastaud,Natália; Vargas,Rosely; Bentancourt,Silvia Maria Puentes.
The Neotropical Ichthyology journal was created in 2003 and soon became one of the main publications in its field as it is reflected in the number of articles submitted every year and the fact that it has been indexed by both SciELO and ISI. In order to understand the reasons for its trajectory, the journal history was recovered and bibliometric indices on author, citation and impact factor were mapped for the period between 2003 and 2010. A descriptive study on journal information source and a bibliometric study of the 388 articles published by the journal and the 642 articles that cite it have been carried out. Bibliometric analyses showed that 75.8% of the articles had been written by Brazilian authors and 91.3% had been published in collaboration. The...

Two New Simple Bibliometric Indexes to Better Evaluate Research in Economics
Provedor de dados: 31
Autores: Anania,   Giovanni; Caruso,   Annarosa.
The paper proposes two new simple indexes - the k and w indexes - to assess a scientist’s publications record based on citations. The two indexes are superior to the widely used h index (Hirsch, 2005), as they preserve all its valuable characteristics and try to overcome one of its known major shortcomings, i.e. that it uses only a fraction of the information contained in a scientist’s citations profile and, as a result, does not show a sufficiently fine ‘granularity’ (the h index is defined over the set of positive integers) to allow a fully satisfactory ranking of scientists. This problem is particularly acute in those disciplines, such as Economics, where scientific productivity and citation practices typically yield fewer citations per paper and, as a...

A retrospective analysis of scientific publications on the deep sea from 1987 to 2016
Provedor de dados: 42
Autores: BOOS,HARRY; RODRIGUES,CHARLES; ARAUJO,PAULA B.
Abstract: The deep sea remains the least known biome. Despite this fact, anthropic activities have affected these regions in various ways. The objective of this study was to outline the scientific production scenario based on deep sea research and to analyze trends present in the literature. For this, the bibliographical resources available from the Web of Science (WoS) were surveyed. Between 1987 and 2016, 11,079 articles on the deep sea were published. Growth was over 100% from the first to second decade and 75% from the second to third. The most productive countries were the USA, Germany, France, England and Japan. Of the 404 journals that published articles on the deep sea, 10% accounted for approximately 60% of the total published articles. The...

Scientometrics: Nature Index and Brazilian science
Provedor de dados: 42
Autores: SILVA,VALTER.
ABSTRACT A recent published newspaper article commented on the (lack of) quality of Brazilian science and its (in) efficiency. The newspaper article was based on a special issue of Nature and on a new resource for scientometrics called Nature Index. I show here arguments and sources of bias that, under the light of the principle in dubio pro reo, it is questionable to dispute the quality and efficiency of the Brazilian science on these grounds, as it was commented on the referred article. A brief overview of Brazilian science is provided for readers to make their own judgment.

Articles with authors affiliated to Brazilian institutions published from 1994 to 2003 with 100 or more citations: II - identification of thematic nuclei of excellence in Brazilian science
Provedor de dados: 42
Autores: Meneghini,Rogerio; Packer,Abel L.
Articles with 100 citations or more in the scientific literature and with at least one author with Brazilian affiliation, were identified in the Thomson-ISI (Institute for Scientific Information) Web of Science bibliometric database covering a 10-year period, from 1994 to 2003 (see Packer and Meneghini 2006); 248 (0.23%) out of a total of 109,916 articles with Brazilian affiliation were identified. This study was primarily carried out to identify thematic nuclei of excellence in research that had major impact in the international literature. Twelve of these nuclei in the fields of Biomedicine, Medicine, Biology, Physic, Chemistry and Astronomy were considered outstanding and their genesis and development were described. The weight of factors such as...

Comparison of scientists of the Brazilian Academy of Sciences and of the National Academy of Sciences of the USA on the basis of the h-index
Provedor de dados: 56
Autores: Mugnaini,R.; Packer,A.L.; Meneghini,R.
A new scientometric indicator, the h-index, has been recently proposed (Hirsch JE. Proc Natl Acad Sci 2005; 102: 16569-16572). The index avoids some shortcomings of the calculation of the total number of citations as a parameter to evaluate scientific performance. Although it has become known only recently, it has had widespread acceptance. A comparison of the average h-index of members of the Brazilian Academy of Sciences (BAS) and of the National Academy of Sciences of the USA (NAS-USA) was carried out for 10 different areas of science. Although, as expected, the comparison was unfavorable to the members of the BAS, the imbalance was distinct in different areas. Since these two academies represent, to a significant extent, the science of top quality...

Brazilian medical publications: citation patterns for Brazilian-edited and non-Brazilian literature
Provedor de dados: 56
Autores: Cunha-Melo,J.R.; Santos,G.C.; Andrade,M.V.
Today, the quality of a scientific article depends on the periodical in which it is published and on the number of times the article is cited in the literature. In Brazil, the criteria for the evaluation of this scientific production are improving. However, there is still some resistance, with authors arguing that Brazilian publications must be preferentially addressed to the national readers and, therefore, they should ideally be written in Portuguese. In order to determine the kind of scientific journals cited in the reference lists of articles published in medical periodicals edited in Brazil, in the present study we determine the rate of Portuguese/English citations. Three issues of 43 periodicals (19 indexed in SciELO, 10 in PubMed, 10 in LILACS, and...

Balance between education- and research-oriented publications from a Brazilian University Hospital
Provedor de dados: 56
Autores: Mendonça de Araujo,K.; Mourão,P.A.S.; Leta,J.
We analyzed the trends of scientific output of the University Hospital, Federal University of Rio de Janeiro. A total of 1420 publications were classified according to pattern and visibility. Most were non-research publications with domestic visibility. With time, there was a tendency to shift from non-research (or education-oriented) publications with domestic visibility to research publications with international visibility. This change may reflect new academic attitudes within the institution concerning the objectives of the hospital and the establishment of scientific research activities. The emphasis of this University Hospital had been on the training of new physicians. However, more recently, the production of new knowledge has been incorporated as...
