Agronegocio del brócoli y semiproletarización. Corolarios del vinculo laboral en una comuna indigena de la sierra central de Ecuador
Full text linkDuring the last three decades of the twentieth century, Latin America went through a process of restoring the outward development model thanks to which the agro-export sector acquires renewed dynamism. The expansion of agribusiness of non-traditional export crops has brought diverse consequences on the peasantry settled in the rural areas of the region. While in some cases it led to their dispossession, in others they were integrated as semi-proletarians in their productive processes. This last modality is that of broccoli agribusiness expansion in the central highlands of Ecuador. In this article we explore the type of labor link that is built between farmers and broccoli companies, based on a case study: that of the indigenous peasant community of Yacubamba. We examine the repercussions of three dimensions: the dynamics of parcel work, consumption habits and participation in community spaces. We identify that although a strong dependence on this source of employment is configured as a way to reach the subsistence of the family group, semi-proletarianization does not trigger a sharp break with the peasant dynamics of these homes, as occurs in other rural areas of the region. The content of the article recovers the results obtained in the research carried out during the preparation of our master's thesis based on the conduct of surveys, interviews and observations on site during the end of 2018 and early 2019.Durante las últimas tres décadas del siglo XX, América Latina transitó por un proceso de restauración del modelo de desarrollo hacia afuera al calor del cual el sector agroexportador adquiere un renovado dinamismo. La expansión del agronegocio de cultivos no tradicionales de exportación ha traido aparejadas diversas consecuencias sobre el campesinado asentado en las áreas rurales de la región. Mientras que en algunos casos condujo a su desposesión, en otros se los integró como semiproletarios en sus procesos productivos. Esta última modalidad es la que adquirió la expansión del agronegocio del brócoli en la sierra central del Ecuador. En este articulo exploramos el tipo de vinculo laboral que se construye entre campesinos y empresas brocoleras, a partir de un estudio de caso: el de la comuna campesino indigena de Yacubamba. Examinamos las repercusiones acarreadas sobre tres dimensiones: la dinámica del trabajo parcelario, los hábitos de consumo y la participación en espacios comunitarios. Identificamos que si bien se configura una fuerte dependencia a esta fuente de empleo como via para alcanzar la subsistencia del grupo familiar, la semiproletarización no desencadena una ruptura tajante con la dinámica campesina de estos hogares, como acontece en otras áreas campesinas de la región. El contenido del articulo recupera los resultados obtenidos en la investigación llevada a cabo durante la elaboración de nuestra tesis de maestria la cual fue construida en base a la realización de encuestas, entrevistas y observaciones in situ durante fines del año 2018 y principios de 2019.ARK: ark:/s25251635/qs1peh/t

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
