Digitaria
No full textLa digitaria (Digitaria eriantha) es una gramínea perenne de ciclo estival, introducida al país a los fines de ser estudiada como alternativa forrajera en regiones semiáridas. La planta es de gran porte y puede superar el metro de altura con hojas densas de color verde intenso, de 1 a 2 cm de ancho. Se adapta a casi cualquier tipo de suelos aunque prospera mejor en los arenosos y arenosos – franco. Precipitaciones anuales a partir de los 400 mm resultan suficientes para que esta especie se desarrolle satisfactoriamente, aunque, obviamente, con menor producción de forraje. Tolera condiciones de escasa fertilidad, aunque su producción disminuye y responde muy bien a la fertilización nitrogenada.Estación Experimental Agropecuaria AnguilFil: Breit, Milton Adrián.

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
Estrategias para el fortalecimiento de las organizaciones de la Agricultura Familiar. La regularización jurídica de la Comisión de los Pobladores de Chos Malal, La Pampa
No full textMuchas organizaciones de la agricultura familiar deben sortear diversas dificultades a la hora de afrontar procesos de regularización jurídica. Algunas de ellas son la falta de un aparato administrativo competente, el acceso a personal idóneo en el territorio o la distancia geográfica de las explotaciones familiares respecto de la sede administrativa, concentrada en la capital provincial. En este trabajo se describe el proceso para lograr la regularización jurídica de la comisión “Pobladores de Chos Malal”, con el fin de generar información relevante y útil para intervenciones similares.Many family farming organizations must overcome various difficulties when facing legal regularization and normalization processes. Some of them are the lack of a competent administrative apparatus, access to suitable personnel in the territory, or the geographical distance of the family farms to the administrative headquarters, concentrated in the provincial capital. This work describes the process to achieve the legal regularization of the "Pobladores de Chos Malal" commission, to generate relevant and useful information for similar interventions.AER Victorica, INTAFil: Molina, Maria Jose.

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
