    Desarrollo y cooperación científico-tecnológica internacional en América Latina

    The article seeks to contribute to the study of international scientific-technological cooperation from and for Latin America. The contributions found in the review of recent literature are organized and presented around different dimensions that contribute to rethink the characteristics and the role of scientific-technological cooperation in Latin American nations. Such contributions are the conceptualizations of development, the views on international cooperation and the characterization of the ways of knowledge production. These contributions can be found on different axes of international scientific-technological cooperation in Latin America. Thus, it is studied to cooperate internationally in matters scientifictechnological, within the framework of the different conceptions of development; also with whom to cooperate in science and technology in the international arena —questioning the association with traditional counterparts and giving way to horizontal relationships with alternative partners— and how emerging organizations and actors cooperate in the new modes of production of knowledge.El artículo busca aportar al estudio de la cooperación científico-tecnológica internacional desde y para América Latina. En éste, se organizan y exponen los aportes encontrados en la revisión de la literatura reciente en torno de distintas dimensiones que contribuyen a repensar las características y el rol de la cooperación científico-tecnológica en las naciones latinoamericanas. Tales aportes son las conceptualizaciones del desarrollo, las miradas sobre la cooperación internacional y la caracterización de los modos de producción de conocimientos. Estos aportes permiten reflexionar sobre diversos ejes de la cooperación científico-tecnológica internacional en América Latina. Así, se estudia para qué cooperar internacionalmente en materia científico-tecnológica, en el marco de las distintas concepciones de desarrollo; con quiénes cooperar en ciencia y tecnología en el ámbito internacional —cuestionando la asociación con contrapartes tradicionales y dando paso a relaciones más horizontales con socios alternativos— y cómo cooperar, a partir de organizaciones y actores emergentes en los nuevos modos de producción de conocimiento

    Capital brasileño y enajenación productiva de la gran burguesía argentina en la posconvertibilidad: un ensayo de interpretación sociológica

    Full text link
    El objetivo del presente trabajo remite a realizar un recorrido por la trayectoria de expansión del capital brasileño en la Argentina desde la salida de la convertibilidad, identificar sus dimensiones, formas y significantes. Para ello se propone un tratamiento dividido en dos momentos. En primer lugar una aproximación de carácter empírico-descriptiva acudiendo a un conjunto de herramentales estadísticos sobre variables representativas, a los fines de poner de manifiesto la relevancia cognitiva del fenómeno. En segundo término, se esbozará un intento de aproximación analítica sobre el carácter y significado del proceso de "brasileñización" de la economía argentina a partir de una propuesta del saber económico con foco en los determinantes históricos y sociales del proceso, perspectiva que se propone superadora del individualismo metodológico neoclásico del análisis económico. Por último se realizará una recapitulación sintética de los principales aspectos del trabajo y se esbozaran una serie de conclusiones.Fil: Avendaño, Rodrigo Daniel.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The 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

    “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 link
    We 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 link
    We 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
