Estudo realizado na Universidade Federal da Bahia, com o objetivo de conhecer e identificar os principais produtores de conhecimentos na area de Filosofia e Ciencias Humanas daquela entidade, bem como os veiculos utilizados para a transferencia do conhecimento gerado. Para a coleta dos dados foi utilizado o Catalogo de Producao Cientifica, Literaria e Artistica, 1994-1996, complementado pelo Sistema Producao Docente. O periodo estudado foi de cinco anos (1995-1999). Os resultados apontam que, do universo de 372 docentes, 63,17% foram responsaveis por um total de 2083 publicacoes, entre livros, capitulos de livros, artigos de periodicos, comunicacoes em eventos e outros. O meio de maior divulgacao da producao cientifica foi o artigo de periodico com 33,41%; seguido das comunicacoes em eventos, com 18,24%; livros, 4,85%; e capitulos de livro, com 13,59%. O portugues foi o idioma de maior incidencia com 96,54% da producao cientifica.Palavras-chave: producao cientifica, filosofia e ciencias humanas.

Intellectual structure in stem cell research: exploring Brazilian scientific articles from 2001 to 2010

Abstract With the advent of co-citation techniques in the 1960’s, studies on citation shifted from simple quantifications of the number of citations per document to more complex analyses focusing on the relationship between citations. The present study seeks to map the scientific and cognitive structure of Brazilian stem cell publications. Brazilian publications from 2001 to 2010 were retrieved from the Web of Science database, and data on journal co-citations were processed with the help of VOSViewer software. The results indicated that Brazilian stem cell publications are characterised by a strong emphasis on co-cited journals in the fields of biochemistry and molecular biology, cell biology and haematology. Such characteristics suggest that Brazilian stem cell research is oriented both towards the treatment of a variety of human diseases and injuries caused by accidents (research with stem cells) as well as the understanding of stem cells’ mechanisms of division, differentiation and self-renewal (research on stem cells), the most promising facet of stem cells. The progress in Brazilian stem cell research likely results from a combination of a federal law established in the 2000’s, which regulates stem cell use and research, and the growth of Brazilian science.

Consumo da informação científica na ciência brasileira: estudo exploratório na temática ceratocone e extração de catarata.

This research analyzes the citations to scientific brazilian journals on Information areas (Archival, Library, Information Science, Documentation and Museology) published in 2009-2010. It aims to identify the most cited journals in papers and thesis by citation analysis. A bibliographic database (ABCDM) was used as source of data. A sample of 100 papers, that was selected randomly, and 70 thesis of Information Science were analyzed. The variables of the research were: the journal title, number of articles with journal citations, citation number and number of articles published. Charts were generated in MS-Excel. The most cited Brazilian journals in the fields of Information are currently Ciencia da Informacao, Perspectivas em Ciencia da Informacao and DataGramaZero.O objetivo desta pesquisa e analisar, de forma comparativa, por categoria de nota, alguns dos indicadores utilizados pela CAPES na avaliacao do desempenho dos Programas de Pos-Graduacao em Matematica no Brasil, referentes ao trienio 2007-2009, a fim de contribuir para a compreensao da complexa metodologia envolvida nas avaliacoes trienais da pos-graduacao. Com base nos indicadores presentes na Planilha Comparativa da Avaliacao Trienal da area de Matematica, Probabilidade e Estatistica do trienio 2007 a 2009, presentes no Portal CAPES, construiram-se tabelas de contingencia para os 26 programas de Pos-Graduacao em Matematica apresentando simultaneamente cada indicador e conceito dos programas. De modo geral, observou-se uma tendencia de associacao de todos os indicadores analisados e o conceito obtido, com programas mais antigos e maiores com melhores notas na avaliacao. Ainda, com excecao de artigos em periodicos Qualis B5, a media de artigos por docente, cresce a medida que cresce a nota do programa.Investigates the reasons that lead the researchers to develop research in science and technology and what are the criteria used to determine the division and partnerships and co-authoring coinvencao. The approach is quantitative, the type of bibliometric study and is used as an instrument of data collection a questionnaire with open and closed questions, sent by e-mail to the researchers. The subjects of this study constitute the researchers who have both patent applications and published articles in the field of Biotechnology. 1049 questionnaires were sent out and 119 responses were obtained, and of these 58 were analyzed by researchers who have both represent articles as patents in its production, during the period from 2001 to 2010. There were differences in the criteria used in the fields. For articles, criteria such as training, interdisciplinary academic subject and bonding are important. For patents, the interdisciplinary subject and the technological link featured prominently.The study of the network dynamics is concerned to identify what types of events occurred in the connections between nodes that led to the formation of the current structure. Understanding these events is to understand the specific ways and strategies that have resulted in a network. This study aims to analyze these events with specific focus on scientific collaboration networks, considering coauthoring relationships and participation in defenses of theses and dissertations. Analyzing more than 11,000 documents specific to the area of Communication Sciences, we propose two characteristic types of events that aim to explain the formation dynamics of networks in the analysis.Examines scientific activity in nanotechnology and agribusiness and the objective is to develop scientific indicators through bibliometrics as a method of analyzing information. We carried out the recovery of articles indexed in the Web of Science from 2001 to 2010 on nanotechnology and agribusiness, and the construction of bibliometric indicators. As for the scientific, the growth was significant, showing steady increase in the number of publications in the area. The results indicate that the United States and China are the leaders in research, and knowledge areas of emphasis, Analytical Chemistry and Environmental Sciences. As subjects of interest have: Pesticides, Water Sensors and Biosensors, and Solo. The journals with the highest number of Biosensors and Bioelectronics were publications and Analytica Chimica Acta. The research contributes to the construction of scientific knowledge on nanotechnology for agribusiness, bibliometrics is an essential tool to quantify the results in any area of science knowledge.Examina o consumo da informacao em duas tematicas do campo da Oftalmologia, ceratocone e extracao de catarata. Procedeu-se a uma analise bibliometrica descritiva de micronivel, empregando-se indicadores de consumo da informacao, isto e, indice de Price, vida media e obsolescencia. O material analisado e composto por artigos indexados pelo SciELO Brasil, no periodo de 2006 a 2010. Os resultados apontam para um envelhecimento do tipo moderado para ambas tematicas. Entretanto, o ceratocone apresentou um declinio do uso da informacao superior a tematica extracao de catarataA recuperacao da producao cientifica por autoria e um desafio para diversos mantenedores de bases de dados, devido a ambiguidade causada por problemas derivados da falta de controle no momento da indexacao. Este estudo apresenta um metodo automatico para verificacao de ocorrencia de erros em dados de autorias da base de producao cientifica da Universidade de Sao Paulo (Dedalus) tomando como base o banco institucional de recursos humanos. Por meio de algoritmos de busca aproximada, compararam-se esses dados com os dados de autoria registrados no banco de producao cientifica de quatro unidades da USP (periodo de 2006-2010). Com base nesse estudo piloto foi possivel estabelecer mecanismos de interoperabilidade entre o banco da producao e os bancos institucionais de recursos humanos, alem de permitir mapear a porcentagem de erros, desenvolver mecanismos de interferencia e estabelecer um cronograma para ampliar o estudo as demais unidades USP, bem como procedimentos de normalizacao.
