    Russell, Jane M.; Guzmán, Maria Victoria; Aguillo, Isidro; Reyes, Francisco Collazo; Mugnaini, Rogério
  • Analysis of co-authorship patterns at the individual level Original Articles

    Glänzel, Wolfgang

    Abstract in Portuguese:

    Os padrões da atividade de publicação, do impacto da citação e comunicação, em geral, mudam ao longo da carreira de um cientista. A mobilidade e as mudanças radicais no ambiente de pesquisa de um cientista ou no seu perfil estão entre os fatores mais espetaculares que têm efeito sobre os padrões de colaboração individuais. Embora a bibliometria, neste nível, deva ser aplicada com o máximo de cuidado, os padrões característicos da colaboração e as mudanças na pesquisa de um cientista individual no curso de sua carreira podem ser bem representados pelos métodos bibliométricos. Uma grande variedade de indicadores e as ferramentas de rede são utilizadas para acompanhar a evolução, visualizar e quantificar o perfil de colaboração e desempenho de pesquisadores individuais. Estes métodos são, no entanto, concebidos para complementar a avaliação baseada na opinião do especialista e em outras avaliações qualitativas, e não devem ser usadas como os únicos instrumentos de avaliação. Este estudo apresenta parte dos resultados publicados em um estudo anterior por Zhang e Glänzel, (2012)4 bem como novas aplicações desses métodos.

    Abstract in English:

    Publication activity, citation impact and communication patterns, in general, change in the course of a scientist's career. Mobility and radical changes in a scientist's research environment or profile are among the most spectacular factors that have effect on individual collaboration patterns. Although bibliometrics at this level should be applied with the utmost care, characteristic patterns of an individual scientist's research collaboration and changes in these in the course of a career can be well depicted using bibliometric methods. A wide variety of indicators and network tools are chosen to follow up the evolution and to visualise and to quantify collaboration and performance profiles of individual researchers. These methods are, however, designed to supplement expert-opinion based assessment and other qualitative assessments, and should not be used as stand-alone evaluation tools. This study presents part of the results published in an earlier study by Zhang and Glänzel (2012)4 as well as new applications of these methods.
  • Scientific communication in Brazil (1998-2012): Indexing, growth, flow and dispersion Artigos Originais

    Mugnaini, Rogério; Digiampetri, Luciano Antonio; Mena-Chalco, Jesús Pascual

    Abstract in Portuguese:

    A produção científica brasileira vem demonstrando ascensão no cenário mundial, o que pode decorrer da internacionalização da ciência nacional e/ou das revistas nacionais. Nesse contexto, este estudo reuniu a produção científica brasileira das bases Web of Science e Scientific Electronic Library Online entre 1998 e 2012, com o fim de analisar como a internacionalização tem influenciado a performance do país. Com base em Zonas de Bradford da produção das diversas áreas, buscou avaliar o aumento do número de revistas em cada uma das zonas, assim como a proporção de artigos publicados em revistas nacionais, ao longo de cinco triênios. Observou-se que o número de revistas indexadas exclusivamente na Scientific Electronic Library Online cresceu no período, com exceção do triênio 4, quando aproximadamente 60% da produção nacional foi publicada em revistas estrangeiras (Web of Science). Notou-se que o aumento mais generalizado do número de revistas das áreas deu-se primeiramente na zona 3 (triênio 2004-2006), depois na zona 2 (triênio 2007-2009) e finalmente na zona 1 (triênio 2010-2012). Já o percentual da produção em revistas nacionais diferenciou três grupos de áreas: ciências sociais e humanas, onde as zonas 1 e 2 são exclusivas de revistas nacionais, e a zona 3 vem dando lugar a publicações estrangeiras; Física, Ciência do Espaço e Imunologia, cuja produção é exclusivamente internacional; e as demais áreas, de ciências exatas e da terra, saúde e biológicas, que vêm aumentando o percentual nas zonas 1 e 2, permanecendo a zona 3 direcionada a publicações internacionais.

    Abstract in English:

    The Brazilian scientific production growth in the international scenario may be due to the internationalization of Brazilian science and journals. Within this context, this study collected Brazilian scientific production from the Web of Science and Scientific Electronic Library Online databases - data from 1998 to 2012 - in order to analyze how internationalization influenced the performance of the country. Based on the Bradford Zones and considering the different fields, the aim of this study is to assess the growth in the number of journals in each zone, as well as the proportion of the papers published in national journals throughout five triennia. It was possible to observe that the number of journals exclusively indexed in Scientific Electronic Library Online increased inthe period, except in the fourth triennium when several journals were also indexed in the Web of Science. However, about 60% of the national production is published in international journals (Web of Science). The most generalized growth in the number of journals from different fields occurred initially in zone 3 (triennium 2004-2006), then in zone 2 (triennium 2007-2009), and finally in zone 1 (triennium 2010-2012). On the other hand, the percentage of production in national journals across the fields presented three different behaviors: in Social andHuman Sciences zones 1 and 2 contains exclusively national journals, and zone 3 is receiving international journals; in Physics, Space Science and Immunology production is exclusively international; in other fields such as Exact & Earth, Health and Biological Sciences there is an increasing percentage of production in national journals in zone 1 and 2, but zone 3 remains international.

En estudios de análisis de red social aplicado a bibliometría y cientometría los autores que publican no son identificados como los más citados y con constancia en la red. El Análisis de Redes Sociales en América de Sur trabaja directamente con el soporte de red social, el capital social, la epidemiología, la salud mental, la depresión, la violencia. Los estudios están vinculados a la medicina y enfermería, psicología, sociología, negocios y economía, física y ciencia de la información.

    Abstract in English:

    The aim of the study is to analyze the scientific productivity in South American countries related to Social Network Analysis in accordance with the representation of the countries, institutions, researchers and their theoretical references (citations used in these productions). The present study spans from 1990 to 2013 (31/05/2013). Bibliographical description was used to discover the status of Social Network Analysis in the scientific literature and the quantitative method to analyze publication and citation frequency data using Bibliometrics and Scientometrics. The data was collected from the Web of Science database, refining the data for the countries selected: Argentina n=166; Brazil n=775; Bolivia n=28; Chile n=179; n=78; Colombia n=78; Ecuador n=19; Paraguay n=8; Peru n=33; Uruguay n=21; Venezuela n=48 no articles were published from Guyana, Falkland Islands, Suriname, retrieving a total of 922 scientific articles. The Statistical Package for the Social Sciences, DetDraw, and CiteSpace were used for the treatment of data. Data showed that Brazil, Argentina, Chile, Venezuela and Peru maintained an especially close relationship with the United States of America. Among the South American countries, the centrality of the network consisted of Brazil, Argentina and Chile. The most outstanding universities were: Universidade de São Paulo, Universidade Federal de Minas Gerais, Universidad de Buenos Aires, Universidad Católica de Chile and Fundação Oswaldo Cruz, of which all focus on cooperation and enable studies of social network analysis to develop, with the main representatives being: Herrmann, HJ Eidgenoessische Technische Hochschule - Switzerland; Carrasco, JA Universidad de Concepción - Chile; Bastos, FI Fundação Oswaldo Cruz - Brazil; Costa, LD Universidade de São Paulo - Brazil; Moll, J Labs D'or Hospital Network - Brazil; Benevenuto, F Universidade Federal de Ouro Preto - Brazil; Gonzalez, MC Universidade Federal de São Paulo - Brazil; Miller, EJ University of Toronto - Canada; Zanette DH Centre Atómico Bariloche - Argentina. As for the citation network, the outstanding Latino scholars were Benevenuto, F, Castilian, C, Lancichinetti, A. However, the field counts on the great contributions of Freeman, LC, Granovetter M, Wasserman, S, Scott, J, Borgatti, SP and Burt, RS. In studies of social network analysis applied to bibliometrics and scientometrics authors who have published are not identified as the most constantly cited ones in the network. Social Network Analysis in South America directly deals with social network support, social capital, epidemiology, mental health, depression, violence. The studies are related to medicine and nursing, psychology, sociology, business and economics, physics and information science.
  • Citation practices as semiotic interpretants of certification of local knowledge in astronomy: Mexico 1952-1972 Artigos Originais

    Collazo-Reyes, Francisco; Flores-Vargas, Xochitl; Muñoz-García, Mitzi Lizeth; Pérez-Angón, Miguel Ángel

    Abstract in Spanish:

    Se estudia la literatura científica en el área de astronomía publicada en México. Para ello se utilizan los textos publicados en el Boletín de los Observatorios de Tonantzintla y Tacubaya, durante un periodo de cambios importantes en la producción y publicación de conocimientos científicos en México, 1952-1972. Se busca identificar, en los textos científicos del Boletín, marcas de afiliación del texto local a los patrones de la comunicación científica moderna. Para ello revisamos las prácticas de citación seguidas en las publicaciones, particularmente las funciones de comunicación de las referencias como elementos retóricos de persuasión, en el proceso de formación del texto científico. Se utiliza una metodología de análisis semiótico basada en el modelo tríadico de formación de conceptos. A través de esta metodología fue posible mostrar nuevos roles de los textos del Boletín en el sistema de la comunicación científica internacional. Interpretantes semióticos que dan cuenta de dos funciones de comunicación adquiridas por los textos: una como fuentes acreditadas y otra como fuentes acreditantes, en el proceso mutuo de certificación de conocimientos seguido en las revistas científicas.

    Abstract in English:

    We studied the scientific literature in the field of astronomy published in the Mexican Journal, Boletín de los Observatorios de Tonantzintla y Tacubaya, from 1952 to 1972. We analyzed the articles published during this important period of great changes in the production and dissemination of scientific knowledge. Our goal is to identify affiliation practices in the patterns of scientific communication. The characteristics of citation practices were reviewed, particularly the communication functions of references as rhetorical elements of persuasion. Semiotic analysis was used, particularly the triadic model of concept formation. Accordingly, it was possible to demonstrate new roles of the Boletín articles within the framework of the system of international communication. Semiotic interpretants reveal two communication functions acquired by the texts: in the first case, sources are accredited, and the second case, sources are accrediting, in a mutual process of certification of knowledge found in scientific journals.

    Zacca-González, Grisel; Vargas-Quesada, Benjamín; Chinchilla-Rodríguez, Zaida; Moya-Anegón, Félix de

    Abstract in Spanish:

    El objetivo de este trabajo fue analizar la evolución del volumen y la visibilidad de la producción científica cubana en Salud Pública y en Medicina para determinar si siguen los mismos patrones de comunicación, y recomendar buenas prácticas de publicación. Se aplicaron indicadores bibliométricos de volumen, visibilidad y colaboración extraídos del portal SCImago Institutions Rankings a partir de datos de Scopus, para el área temática Medicine y la categoría Public Health, Environmental and Occupational Health, período 2003-2011. Cuba tiene una posición relativamente alta en los rankings de volumen de producción científica tanto en Medicina como en Salud Pública en los contextos internacionales y regionales, mientras que en impacto está entre los últimos países. La tendencia de la producción es al crecimiento, aunque en Salud Pública es más acelerado. El liderazgo es alto, pero la colaboración internacional está por debajo de lo esperado. La publicación en revistas de alto impacto (primer cuartil) y los artículos en el 10% más citado (excelencia) son escasos. Se concluye que el volumen y el impacto de la publicación no están acorde al potencial científico de salud cubana. Se recomienda incrementar la colaboración científica, la publicación de artículos en revistas de alto impacto, la preparación de los recursos humanos y seguir las recomendaciones internacionales sobre las buenas prácticas de edición y publicación científica.

    Abstract in English:

    The aim of this study was to analyze the evolution of the quantity and visibility of Cuban scientific production in Public Health and Medicine to determine if they follow the same patterns of scientific communication and the recommended best practices for publication. Bibliometric indicators of quantity, visibility and cooperation were extracted from the SCImago Institutions Rankings website, which is based on Scopus data, in the field of Medicine and category of Public Health, Environmental and Occupational Health from 2003 to 2011.Cubahas a relatively high position in the rankings of scientific production in both Medicine and Public Health within the international and regional contexts, but its impact is ranked among the last countries. The production trend of both fields has increased, but public health is increasing faster. Leadership is high, but international collaboration is below expectations. Publication in high impact journals (first quartile) and articles in the set 10% most cited documents (excellence) are scarce. Thus, it may be concluded that the volume and impact of publication are not in accordance with the scientific potential of Cuban health. We recommend increasing scientific cooperation, publishing articles in high impact journals, training human resources and following the international recommendations for good editorial and scientific publication practices.
  • Knowledge organization in the dynamics of research in the scientific literature of articles at Brapci Artigos Originais

    Freitas, Juliana Lazzarotto; Nascimento, Bruna Silva do; Bufrem, Leilah Santiago

    Abstract in Portuguese:

    Este artigo analisa as dimensões de pesquisa expressas concretamente na literatura da área de Organização do Conhecimento. Considera que a produção científica desenvolvida em determinados contextos sociais e momentos históricos reflete as mudanças e contradições desse contexto, tanto em sua organização interna quanto em suas aplicações. Questiona como se configuram as relações entre as opções metodológicas adotadas nessa literatura e o processo dinâmico de pesquisa sob a ótica multidimensional. Ilustra esse processo de análise a partir de um corpus de 105 artigos recuperados da Base Referencial de Artigos de Periódicos em Ciência da Informação, entre 2003 e 2012. Utiliza os softwares Endnote e Excel para organização e análise dos dados coletados. Categoriza os artigos de pesquisa sob o ponto de vista de seu objeto e delineamento metodológico, bem como de suas relações teóricas por meio de estudo de citação. Evidencia os autores mais expressivos e atuantes na área de Organização do Conhecimento no Brasil. Identifica os periódicos mais devotados ao tema e conclui que a produção científica brasileira sobre o tema distribui-se de maneira irregular ao longo do período analisado, tendo seu ápice no ano de 2011, durante o qual são publicados 18,27% dos artigos. Finaliza estabelecendo relações entre as correntes teóricas da Organização do Conhecimento e os enfoques e temáticas predominantes no corpus. Os enfoques de pesquisa de maior incidência foram o teórico e o linguístico, e o tipo de análise foi documental.

    Abstract in English:

    The aim of this paper is to analyze the research dimensions expressed in the literature in the field of knowledge organization. We consider that scientific investigation developed in certain social contexts and historical conjunctures reflects the changes and contradictions present in these contexts, both in its organization and applications. This process is illustrated from a corpus of 105 articles retrieved from the referential database of journal articles on Information Science between 2003 and 2012. Endnote and Excel software were used for organizing and analyzing the data collected. The articles are categorized according to their object and methodological approach, as well as their theoretical foundations through the study of citations. Throughout this investigation, we point out the most expressive and active authors in the field of knowledge organization in Brazil. We also identify the journals that are more devoted to the theme and we conclude that Brazilian scientific production on the theme is irregularly distributed over the period of time analyzed, peaking in 2011 when 18,27% of the total number of articles were published. We conclude by establishing the relationship between theoretical currents of knowledge organization and the prevalent approaches and themes found in the corpus. The focus of the most prevalent research approaches were the theoretical and linguistic approaches and the type of analysis was documentary.
  • Marketing in the field of information disciplines: Research trends in Latin America (1985-2012) Artigos Originais

    González-Valiente, Carlos Luis

    Abstract in Spanish:

    Se esclarecen las tendencias de investigación relativas a la mercadotecnia en el campo de las disciplinas informativas, a partir de la producción científica de América Latina. Se utiliza como fuente de consulta las revistas electrónicas indizadas por el Directorio Latindex. Se recuperaron 108 registros bibliográficos a los cuales se les aplicaron los indicadores bibliométricos de productividad por años, revistas, autores, idioma y análisis de coocurrencia de términos. Se evidencia que el mayor índice de productividad radica en el contexto de las revistas, idioma y autores brasileños. Tras el análisis de coocurrencia se conformaron cuatro clúster principales que denotaron como tópicos más tratados: la mercadotecnia del profesional de la información en el mercado de trabajo, la mercadotecnia en bibliotecas, la mercadotecnia de productos y servicios de información, y la gestión de información de mercadotecnia. Desde otro punto de vista se identificaron tendencias a partir de cuatro rasgos en las investigaciones, tales como: el objeto mercadotécnico, el contexto organizacional, la perspectiva disciplinar y las técnicas y herramientas de marketing más exploradas. Se comprobó que el marketing en las Ciencias de la Información es un tópico que no ha estado ajeno a la investigación en la región latinoamericana, además se logró caracterizar la productividad de un grupo de revistas (51.4%) que no son indizadas por bases de datos de la corriente principal.

    Abstract in English:

    This study seeks to clarify research trends related to marketing in the field of information disciplines from Latin American scientific production. As a reference source, we used the electronic journals indexed in the Latindex Directory. Some bibliometric indicators were applied to 108 documents; these indicators were as follows: productivity by year, journals, authors, language, and finally term cooccurrence analysis. It was evident that the highest rate of productivity was found in Brazilian journals and authors, and in the Portuguese language. The four main clusters in term co-occurrence analysis in the most relevant topics were as follows: marketing of the information professional in the labor market, library marketing, marketing of information products and services, and marketing information management. From another point of view, four kinds of traits were also identified, as follows: the marketing object, organizational context, disciplinary perspective, and the most commonly used marketing tools and techniques. It wasfound that marketing in Infomation Sciences is a relevant topic in the Latin American research activity. In addition, it was possible to establish the productivity of some journals (51.4%) that are not included in the most relevant databases.
