Agronegocio y violencia : dinámicas locales de un modelo global
No full textFil: Luna, David Hernán. Universidad Nacional del Nordeste. Facultad de Humanidades; Argentina.Fil: Luna, David Hernán. Consejo Nacional de Investigaciones Científicas y Técnicas; Argentina.Lo que podría denominarse "lo rural" en el Chaco, contrario a lo que algunas nostalgias populares mitificadas profesan, al respecto de las epopeyas fundacionales y de las características materiales del paisaje, ha sido escenario de múltiples y permanentes procesos de transformación (Echeverría, 2004). Sin embargo, no hubo hasta ahora un periodo donde se profundice de manera tan acelerada los cambios impuestos para el desarrollo productivo imperante a escala global, ya que en los últimos diez años: 100.000 personas han dejado de vivir en ámbitos rurales de la provincia para radicarse en pueblos y ciudades; el 2% de los productores tiene formas de propiedad y tenencias sobre más del 50% de la tierra, al mismo tiempo, más de un 15% de pequeños y medianos productores desaparecieron del escenario productivo, en general absorbidos por productores locales capitalizados y capitales extraterritoriales
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Economía Campesina: Convivencia o dependencia con el capitalismo hegemónico.
Get PDFHay en la Ciencias Sociales un amplio y actual énfasis sobre economías alternativas al orden hegemónico capitalista, la economía campesina se presenta como una de ellas, al mismo tiempo que revive el debate acerca de que si es posible construir economías alternativas al interior de un orden económico global que genera dependencia como mecanismo central de funcionamiento.Los interrogantes que se presentan ante esta serie de planteos son: ¿puede la económica campesina de subsistencia convertirse en una alternativa a la economía capitalista? o ¿En qué medida las economías pueden ser "alternativas" (en el sentido estricto del término) cuando sus condicionamientos y posibilidades son determinados por una economía hegemónica? Intentaremos contribuir con este debate tan necesario en el campo de las ciencias sociales.Fil: Luna, David Hernán. Consejo Nacional de Investigaciones Científicas y Técnicas.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
