This paper is the result of the Masters dissertation studying the role and history of scientific communication, especially the changes that have occurred after the appearance of electronic communication and computer networks. This study showed that hypertext systems are increasingly being used in the scientific and academic world in the production of electronic journals; this makes it possible for the user to rapidly access information in their area. However, these systems need to be improved to help the user during search and access to information. Both printed journals migrating to electronic media, and the exclusively electronic journals should present the current quality indicators. The attempt was made to discover whether characteristics related to printed journals are being maintained in their electronic counterparts. For this, a prototype model was developed to analyze the structure of electronic scientific journals; it composes 14 criteria expressing aspects of quality for these journals. It includes elements of Website Information Architecture and those already in place in printed scientific journals in order to ensure that basic functions - archiving and dissemination - are maintained in electronic publishing. Each criterion consists of variables, which measure the maintenance of these functions both in the migrating printed journals and the exclusively electronic ones. This prototype model was used to analyze Ciência da Informação On-line and DataGramaZero - Revista de Ciência da Informação. Results indicate that this model is able to find out if the basic functions of archiving and dissemination are being maintained in electronic journals. Therefore, its implementation is justified in electronic journals. The model can help librarians, authors, and users of electronic journals to identify quality journals, and assist editors in developing their projects. The material from the study may be included in the preservice and inservice education of Information Science professionals and to support editors of scientific journals.

Introduction: Open access publishing is becoming increasingly popular within the biomedical sciences. SciELO, the Scientific Electronic Library Online, is a digital library covering a selected collection of Brazilian scientific journals many of which provide open access to full-text articles. This library includes a number of dental journals some of which may include reports of clinical trials in English, Portuguese and/or Spanish. Thus, SciELO could play an important role as a source of evidence for dental healthcare interventions especially if it yields a sizeable number of high quality reports. Objective: The aim of this study was to identify reports of clinical trials by handsearching of dental journals that are accessible through SciELO, and to assess the overall quality of these reports. Material and methods: Electronic versions of six Brazilian dental Journals indexed in SciELO were handsearched at www.scielo.br in September 2008. Reports of clinical trials were identified and classified as controlled clinical trials (CCTs - prospective, experimental studies comparing 2 or more healthcare interventions in human beings) or randomized controlled trials (RCTs - a random allocation method is clearly reported), according to Cochrane eligibility criteria. Criteria to assess methodological quality included: method of randomization, concealment of treatment allocation, blinded outcome assessment, handling of withdrawals and losses and whether an intention-to-treat analysis had been carried out. Results: The search retrieved 33 CCTs and 43 RCTs. A majority of the reports provided no description of either the method of randomization (75.3%) or concealment of the allocation sequence (84.2%). Participants and outcome assessors were reported as blinded in only 31.2% of the reports. Withdrawals and losses were only clearly described in 6.5% of the reports and none mentioned an intention-to-treat analysis or any similar procedure. Conclusions: The results of this study indicate that a substantial number of reports of trials and systematic reviews are available in the dental journals listed in SciELO, and that these could provide valuable evidence for clinical decision making. However, it is clear that the quality of a number of these reports is of some concern and that improvement in the conduct and reporting of these trials could be achieved if authors adhered to internationally accepted guidelines, e. g. the CONSORT statement.

This work identifies and analyzes literature about knowledge organization (KO), expressed in scientific journals communication of information science (IS). It performs an exploratory study on the Base de Dados Referencial de Artigos de Periodicos em Ciência da Informacio (BRAPCI, Reference Database of Journal Articles on Information Science) between the years 2000 and 2010. The descriptors relating to "knowledge organization" are used in order to recover and analyze the corresponding articles and to identify descriptors and concepts which integrate the semantic universe related to KO. Through the analysis of content, based on metrical studies, this article gathers and interprets data relating to documents and authors. Through this, it demonstrates the development of this field and its research fronts according to the observed characteristics, as well as noting the transformation indicative in the production of knowledge. The work describes the influences of the Spanish researchers on Brazilian literature in the fields of knowledge and information organization. As a result, it presents the most cited and productive authors, the theoretical currents which support them, and the most significant relationships of the Spanish-Brazilian authors network. Based on the constant key-words analysis in the cited articles, the co-existence of the French conception current and the incipient Spanish influence in Brazil is observed. Through this, it contributes to the comprehension of the thematic range relating to KO, stimulating both criticism and self-criticism, debate and knowledge creation, based on studies that have been developed and institutionalized in academic contexts in Spain and Brazil.

Apesar do reconhecimento da importância dos conhecimentos geográficos e do uso das ferramentas de análise espacial nos estudos da saúde coletiva, esse é um campo ainda pouco explorado pelos pesquisadores brasileiros. em levantamento realizado nas principais revistas científicas que veiculam os resultados de pesquisa em saúde do trabalhador, verificou-se o grande predomínio do uso de tabelas e gráficos como meio de organizar e apresentar os resultados obtidos, e o número reduzido de mapas. Para isso foram examinados todos os artigos publicados em quatro periódicos (Revista de Saúde Pública, Cadernos de Saúde Pública, Revista Saúde e Sociedade e Revista Brasileira de Epidemiologia) no período de 1967 a 2009. Uma vez analisado o conjunto de artigos selecionados no estudo, aqueles que utilizaram representações cartográficas receberam atenção especial. Verificou-se que, embora ainda pouco utilizadas, as ferramentas do geoprocessamento e da geoestatística com suporte em SIG abrem um campo de novas possibilidades no uso da cartografia temática em saúde do trabalhador no Brasil. Contudo, recomenda-se para os editores das revistas científicas o detalhamento de normas técnicas para publicação de figuras cartográficas, assim como a elaboração de pareceres específicos que possam auxiliar os autores em vista das modificações necessárias para a melhoria da qualidade da comunicação visual de mapas e da correlação espacial por meio do tratamento cartográfico.

OBJETIVO: Estudar as normas relativas à ética da pesquisa em seres humanos contidas nas Instruções aos Autores de revistas científicas brasileiras. MATERIAL E MÉTODOS: As Instruções aos Autores de 139 revistas científicas brasileiras das áreas de medicina, biomedicina, enfermagem, odontologia e ciências gerais foram analisadas com relação às suas recomendações sobre os aspectos éticos. RESULTADOS: Das 139 revistas estudadas, 110 (79,1%) não fazem referências aos aspectos éticos; 17 (12,2%) exigem aprovação prévia pela Comissão de Ética; três (2,1%) fazem referência à Declaração de Helsinque; uma (0,7%) recomenda adotar o consentimento esclarecido; cinco (3,5%) seguem orientações dos requisitos uniformes para manuscritos submetidos a revistas biomédicas e três (2,1%) seguem princípios, normas e padrões éticos não especificados. Nas 29 revistas que fazem referências à ética, as exigências são solicitadas sob as seguintes formas: 15 (51,7%) exigem a inclusão da informação no texto do artigo; duas (6,8%) pedem carta assinada pelos autores; uma (3,4%) solicita cópia da autorização da Comissão de Ética; uma (3,4%) afirma supor que o autor cumpriu as exigências e dez (34,4%) não fazem qualquer referência específica. CONCLUSÕES: Os resultados do estudo indicam que na maioria das revistas científicas brasileiras há pouca preocupação em relação aos aspectos éticos da pesquisa em seres humanos, contidas nas Instruções aos Autores. Nas revistas que fazem referência aos aspectos éticos, as exigências são muito variáveis.

O artigo é uma resposta ao trabalho de Piccolo, Moscardini e Costa, publicado no volume 16, número 1 deste periódico, no qual os autores analisaram a minha produção bibliográfica publicada em periódicos científicos. Alguns fatos da minha vida pessoal, intimamente ligados à trajetória acadêmica percorrida, são descritos com o intuito de favorecer a compreensão radical da minha posição teórica. As referências que dão suporte ao artigo foram, em boa parte, publicadas há algumas décadas. Isto se deve ao fato de que grandes contribuições teóricas nas Ciências Humanas ocorreram em meados do século passado. Significa que a preocupação excessiva com a atualidade das referências, avaliada em termos de cronologia, leva os pesquisadores a abrirem mão da vasta e rica sistematização teórica daquele período.

Scientific development that has been achieved through decades finds in clinical research a great possibility of translating findings to human health application. Evidence given by clinical trials allows everyone to have access to the best health services. However, the millionaire world of pharmaceutical industries has stained clinical research with doubt and improbability. Study results (fruits of controlled clinical trials) and scientific publications (selective, manipulated and with wrong conclusions) led to an inappropriate clinical practice, favoring the involved economic aspect. In 2005, the International Committee of Medical Journal Editors (ICMJE), supported by the World Association of Medical Editors, started demanding as a requisite for publication that all clinical trials be registered at the database ClinicalTrials.gov. In 2006, the World Health Organization (WHO) created the International Clinical Trial Registry Platform (ICTRP), which gathers several registry centers from all over the world, and required that all researchers and pharmaceutical industries register clinical trials. Such obligatory registration has progressed and will extend to all scientific journals indexed in all worldwide databases. Registration of clinical trials means another step of clinical research towards transparency, ethics and impartiality, resulting in real evidence to the forthcoming changes in clinical practice as well as in the health situation.
