Oportunidades para el desarrollo de la porcicultura en Tucumán y el Norte Argentino
No full textDiez aspectos claves que resumen las condiciones del sector en el NOA. Condiciones agroecológicas favorables: Tucumán y el norte argentino poseen condiciones ideales como disponibilidad de agua, clima adecuado y tierras fértiles, para el crecimiento de la actividad porcina. Aunque existe una tendencia hacia la concentración productiva en la región, predominan aún los pequeños y medianos productores familiares (1). Estos, generalmente no agrupados, integran la cría de cerdos en sistemas diversificados, contribuyendo significativamente al arraigo rural de las familias.Instituto de Investigación Animal del Chaco SemiáridoFil: Macedo, Maria Ruth.

El cultivo del maíz en los sistemas minifundistas y del pequeño productor familiar
No full textEn la región del Noroeste el maíz fue parte del desarrollo de las culturas precolombinas, y a la fecha el maíz continúa vigente en nuestro acervo cultural, formando parte de la producción empresarial y también com ou nelemento importante en las economías de subsistencia del minifundio y del pequeño productor familiar.Instituto de Investigación Animal del Chaco SemiáridoFil: Geronimo Gomez, Luis.

Alimentación [Porcinos]

Por eso es muy importante saber QUÉ, CÓMO, CUÁNTO Y CUÁNDO darles de comer.Instituto de Investigación Animal del Chaco SemiáridoFil: Zimerman, Maria.

El cultivo del maíz en la agricultura familiar el Noroeste Argentino
No full textLa 1era publicación de maíz para pequeños productores, editada en noviembre del 2007, refleja el trabajo conjunto de investigadores y extensionistas del Instituto de Investigación Animal del Chaco Semiárido (ex INTA Leales) en esta temática con tecnología apropiada para la zona de influencia del
departamento Leales, provincia de Tucumán. En esta nueva publicación, nuestro propósito es aportar conceptos sobre cómo y por qué suceden las cosas, como le gusta decir a Luis Gerónimo Gómez, para entender entonces las propuestas que recomendamos.Instituto de Investigación Animal del Chaco SemiáridoFil: Gerónimo Gómez, Luis.

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
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
