A profile of the impact of Acta Botanica Brasilica: reflections on how to improve visibility and recognition of a scientific journal Acta Botanica
Scarano,Fabio Rubio; De Toni,Karen; Amarante,Cristiana Vasconcellos Goulart.
We have estimated the ISI-impact factor of Acta Botanica Brasilica for the past six years, calculated the journal's h-index, calculated the journal's self-citation, examined country and institutions of origin of the papers that cite Acta papers, and examined scope and profile of the most-cited papers published by the journal. Results demonstrated a steep rise in impact factor and citation frequency in 2008, which is most encouraging, but also revealed that the journal is below the level of maturity expected of a 20-year old journal. Visibility of the journal is mostly national although, surprisingly, journal's self-citation of 12% is fairly low. We use Acta as an example to discuss possible strategies to enhance the international visibility of botanical...

An overview of Brazilian mammalogy: trends, biases and future directions Rev. Bras. Zool.
Brito,Daniel; Oliveira,Leonardo C.; Oprea,Monik; Mello,Marco A. R..
Mammals are among the most charismatic and well-studied organisms, and Brazil harbors the largest mammal diversity of the world. The Brazilian Society of Mammalogy was established in 1985, and since 2001 it organizes the Brazilian Congress of Mammalogy. We used the proceedings of all three editions of this congress together with papers indexed in Web of Science and Scielo to evaluate trends in Brazilian mammalogy. All contributions were categorized according to mammalian order, biome, topic of research and state of authors' affiliation. Our results show that mammalian orders with higher species richness receive more attention, but the ranking is different between abstracts and papers. Higher species richness did not translate into more attention for more...

Assessment of the scientific-technological production in molecular biology in Brazil (1996-2007): the contribution of genomics programs Anais da ABC (AABC)
Meneghini,Rogério; Gamba,Estêvão C..
Several genome sequencing programs were launched in Brazil by the end of the nineties and the early 2000s.The most important initiatives were supported by the ONSA program (http://watson.fapesp.br/onsa/Genoma3.htm) and aimed at gaining domain in genomic technology and bringing molecular biology to the state of art. Two mainsets of data were collected in the 1996-2007 period to evaluate the results of these genome programs: the scientific production (Scopus and Web of Science databases) and the register of patents (US Patent and Trademark Office), both related to the progress of molecular biology along this period. In regard to the former, Brazil took a great leap in comparison to 17 other developed and developing countries, being only surpassed by China....

Brazilian impact factor of physics journals - the third side of the coin Anais da ABC (AABC)
Mohallem,José R.; Fonseca,Norma E. da.
The lack of correlation between the Journal Impact Factors and the most cited Brazilian papers in physics is statistically demonstrated. The existence of an effective "Brazilian Impact Factor" is observed, being its values, in general, lower than the international Impact Factors. In some cases, discrepancies from the international values are huge, leading to doubts on whether it is appropriate to use this indicator to judge Brazilian scientists.

Citations to papers from Brazilian institutions: a more effective indicator to assess productivity and the impact of research in graduate programs BJMBR
Meneghini,R..
A recent assessment of 4400 postgraduate courses in Brazil by CAPES (a federal government agency dedicated to the improvement of the quality of and research at the postgraduate level) stimulated a large amount of manifestations in the press, scientific journals and scientific congresses. This gigantic effort to classify 16,400 scientific journals in order to provide indicators for assessment proved to be puzzling and methodologically erroneous in terms of gauging the institutions from a metric point of view. A simple algorithm is proposed here to weigh the scientometric indicators that should be considered in the assessment of a scientific institution. I conclude here that the simple gauge of the total number of citations accounts for both the productivity...

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 BJMBR
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...

Global literature of fiddler crabs, genus Uca (Decapoda, Ocypodidae): trends and future directions Iheringia, Sér. Zool.
Nabout,João C.; Bini,Luis M.; Diniz-Filho,José A. F..
Crabs of the genus Uca Leach, 1814 are characterized by having strong sexual dimorphism and a global distribution. Currently, 97 species have been described and analyzed under several aspects, including population ecology, physiology and ethology. However, there is no general summary of the information from the various literatures. The aim of this study is to perform a scientometric analysis of fiddler crab studies. For this we searched papers available in the Thomson ISI database that contained the words "Uca" OR "fiddler* crab*" between the years 1991 and 2007. For each paper, we researched and recorded the following characteristics: publication year; journal of publication; the first author's nationality; the country where the study was conducted; study...

H-index in the Brazilian Academy of Sciences: comments and concerns Anais da ABC (AABC)
Kellner,Alexander W.A.; Ponciano,Luiza C.M.O..
Bibliometric parameters have been used in order to evaluate a scientist's performance. The h-index has been gradually accepted as the most adequate parameter for this purpose. To have an idea of this index among Brazilian scientists, we performed an analysis of this parameter for the full members of the Brazilian Academy of Sciences (BAS). The h-index of 402 members listed in 10 distinct categories by the BAS was determined, cross-checked with the curriculum vitae of each of them listed at the Plataforma Lattes database (CVL) and compared with each other. Despite the large production, mostly in journals without impact factor, the h-indexes among the BAS members are comparatively low and show a large variation in all of the 10 categories, particularly in...

ABSTRACT Latin America embodies countries of special interest for ecological studies, given that areas with great value for biodiversity are located within their territories. This highlights the importance of an evaluation of ecological research in the Latin America region. We assessed the scientific participation of Latin American researchers in ecological journals, patterns of international collaboration, and defined the main characteristics of the articles. Although Latin American publications have increased in fourteen years, they accounted up to 9% of publications in Ecology. Brazil leaded the scientific production in Latin America, followed by Argentina and Mexico. In general, Latin American articles represented a low percentage of most journals...

Scientometric indicators for Brazilian research on High Energy Physics, 1983-2013 Anais da ABC (AABC)
ALVAREZ,GONZALO R.; VANZ,SAMILE A.S.; BARBOSA,MARCIA C..
ABSTRACT This article presents an analysis of Brazilian research on High Energy Physics (HEP) indexed by Web of Science (WoS) from 1983 to 2013. Scientometric indicators for output, collaboration and impact were used to characterize the field under study. The results show that the Brazilian articles account for 3% of total HEP research worldwide and that the sharp rise in the scientific activity between 2009 and 2013 may have resulted from the consolidation of graduate programs, the increase of the funding and of the international collaboration as well as the implementation of the Rede Nacional de Física de Altas Energias (RENAFAE) in 2008. Our results also indicate that the collaboration patterns in terms of the authors, the institutions and the countries...
