La ciencia como parte de un modelo de país donde los pueblos originarios no estaban incluidos.
El legado de los abuelos.Fil: Reyna, Pablo. Universidad Nacional de Córdoba; Argentina.Fil: Ludueña, Diego. Universidad Nacional de Córdoba. Prosecretaría de Comunicación Institucional. UNCiencia; Argentina.Los miembros de las comunidades originarias reivindican su existencia de forma continua desde tiempos ancestrales hasta la actualidad. Su historia se contrapone a la memoria oficial sobre estas comunidades que hoy, organizadas y en lucha, disputan su lugar en la sociedad.
En primera persona, miembros de las comunidades comechingonas de La Toma –de la ciudad de Córdoba–, Timoteo Reyna y Chavascate –ambas de Villa Cerro Azul–, y Las Palmas –del Paraje Santa Teresita Sierra de Pocho– ponen en palabras las marcas que la política de invisibilización del Estado dejaron en sus historias familiares.

Identificación y caracterización de begomovirus en cultivos de poroto (Phaseolus Vulgaris l.), ajuste de marcadores moleculares para la búsqueda de resistencia y evaluación fenotípica
Get PDFTesis para obtener el grado de Doctor en Ciencias Biológicas, presentada en la Universidad Nacional de Córdoba, en 2022Dentro del conjunto de legumbres secas, el poroto (Phaseolus vulgaris L.) constituye un cultivo relevante que es producido en áreas tropicales y subtropicales del mundo. En Argentina, bajo condiciones de secano y en forma extensiva, es cultivado en la región noroeste. Existen diversos factores que afectan la estabilidad de su producción, entre ellos se destacan las enfermedades virales ocasionadas por begomovirus.
Los objetivos del presente trabajo fueron: (i) Detectar la presencia de begomovirus en lotes de producción de poroto y en malezas aledañas en Argentina, (ii) Identificar y caracterizar nuevas especies, (iii) Determinar su probabilidad de incidencia a través de variables biometeorológicas, (iv) Evaluar el comportamiento de cultivares de poroto frente a sus infecciones y (v) Analizar una selección de germoplasma a través del ajuste de marcadores moleculares ligados a genes de resistencia a estos patógenos.Within the dry legumes, the common bean (Phaseolus vulgaris L.) constitutes a relevant crop which is produced in tropical and subtropical áreas of the world. In Argentina, is cultivated under dry and extensive conditions in the northwestern region. There are several factors that affect the stability of its production, among them are viral diseases caused by begomoviruses.
The objectives of this work were: (i) To detect the presence of begomoviruses in bean production fields and neighboring weeds in Argentina, (ii) To identify and characterize new begomovirus species, (iii) To determine their probability of incidence through biometeorological variables, (iv) To evaluate the behavior of common bean cultivars against begomovirus infections and (v) To evaluate a selection of germplasm through the adjustment of molecular markers linked to resistance genes to these pathogens.Instituto de Patología VegetalFil: Reyna, Pablo Gastón.

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
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
