Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Ciencia, tierra y poder: uso y apropiación territorial de las tierras públicas en el Suroeste Paulista
No full textO presente trabalho se propõe a debater a questão das terras públicas na região Sudoeste Paulista, compilar informações sobre localização, posse e uso das áreas existentes, promovendo uma análise crítica sobre a situação de uso destas na atualidade e as disputas e possibilidades de destiná-las para projetos de assentamentos de trabalhadores rurais sem terras, a partir da discussão sobre a questão agrária e o avanço do agronegócio, desenvolvimento e função socioambiental da propriedade pública. A área de abrangência deste estudo foi a região de Itapeva, delimitada a partir da definição de regiões administrativas do governo do estado de São Paulo. Nesse contexto e espaço geográfico, há um contraste e contradição entre um elevado grau de desenvolvimento do agronegócio, com extensas áreas cultivadas com soja e espécies madeiráveis destinadas à indústria de papel e celulose e uma intensa atividade mineradora; com uma população empobrecida que sobrevive e resiste em meio a esse processo de expansão, e que a cada dia se vê alijada das poucas possibilidades de trabalho temporário na agricultura, em uma região basicamente agrícola. Outra reflexão presente neste trabalho será sobre o papel da produção técnico-científica para a promoção de distintos projetos societários, representados pelo projeto do agronegócio orientado pela lógica de reprodução e acumulação de capital e da reforma agrária desde a lógica dos movimentos sociais de luta pela terra na atualidade, orientados pela lógica da reprodução da vida e respeito aos limites da natureza. As terras públicas existentes na região, de modo geral, estão sob domínio de instituições de ensino, pesquisa, extensão e fomento, portanto seu uso deve estar voltado essencialmente para a produção de ciência e tecnologia e cumprir função socioambiental, buscando garantir condições de vida digna e acesso a um ambiente saudável para o conjunto da sociedade, o que pressupõe a adoção por parte do aparato estatal de mecanismos de gestão e controle democráticos. Porém, estas áreas, na atualidade são foco de conflitos e disputas envolvendo latifúndio-agronegócio, Estado e trabalhadores rurais sem terras, a partir de projetos completamente antagônicos e não se observa a existência de mecanismos de controle social e territorial democrático da gestão e da decisão sobre o uso destas.The present paper proposes to discuss the question of public rural properties in the Southwest of São Paulo region, to compile information about localization, ownership and utilization of the existing areas. Promoting a critical analysis about the status of use of these in the present and the disputes and possibilities of assigning them for projects of settlements of landless workers, from the discussion about agrarian question and the advance of agribusiness, development and socioenvironmental function of public property. The scope of this study is the region of Itapeva, delimited from the definition of administrative regions of the state government of São Paulo. In this context and geographic space, there is a contrast and contradiction between a high level of development of agribusiness, with extensive areas cultivated with soybeans and wood’s species for the cellulose and paper industry and an intense mining activity; with a poor population who survives and resists in the midst of this process of expansion, and who every day they feel expelled the few temporary labor opportunities in agriculture, in an agricultural region basically. Another reflection in this paper will be about the role of technical-scientific production for the promotion of different corporate projects, represented by the agribusiness project oriented by the logic of reproduction and capital accumulation and from the agrarian reform since the logic of the social movements of struggle for the land at present, guided by the logic of the reproduction of life and respect for the limits of nature. The public lands in the region, in general, are in control of institutions of education, research, extension and development, therefore its use must be directed essentially to the production of science and technology and fulfill your socioenvironmental function, seeking to ensure dignified living conditions and access to a healthy environment for society as a whole, what presupposes the adoption by the state apparatus of mechanisms of democratic management and control. But, these areas, in fact, they are the focus of conflicts and disputes involving the latifundio-agribusiness, State and landless workers, from completely antagonistic projects and the existence of mechanisms of democratic social and territorial control of the management and the decision on their use is not observed.El presente trabajo se propone discutir la cuestión de las tierras públicas en la región Suroeste Paulista, compilar informaciones sobre localización, posesión y uso de las áreas existentes, promoviendo un análisis crítico sobre la situación de uso de éstas en la actualidad y las disputas y posibilidades de destinarlas para proyectos de asentamientos de trabajadores rurales sin tierra a partir de la discusión sobre la cuestión agraria y el avanzo del agronegocio, desarrollo y función socio-ambiental de la propiedad pública.
