Avanzar a ciegas : un recorrido sonoro por la trayectoria académica de las personas con diversidad funcional visual en la Facultad de Ciencias Sociales de la UBA
No full textLa tesina propone un análisis de las representaciones en torno a las personas con discapacidad visual en la Facultad de Ciencias Sociales de la Universidad de Buenos Aires. Esta dimensión se presenta articulada con trayectorias educativas específicas. A partir de una producción sonora, se presentan las perspectivas de diferentes actores institucionales, con especial énfasis en las voces de estudiantes y graduados ciegos. El informe escrito expone el marco teórico sobre la base del cual se planificaron las entrevistas y se diseñó la propuesta sonora. A su vez, complementa y profundiza el análisis mediante la relación de las herramientas teóricas con los testimonios. Los aportes teóricos sustentan la perspectiva de la construcción histórica y social de la discapacidad, a partir de criterios de normalidad. Como aspecto complementario, detalla las referencias a las personas ciegas en la Convención sobre los Derechos de las Personas con Discapacidad. Asimismo, sintetiza las concepciones en torno a la discapacidad vigentes en diferentes momentos históricos.Fil: Belloni, Federico Daniel. Universidad de Buenos Aires. Facultad de Ciencias Sociales.

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
Coordination of active current limiters and hybrid circuit breakers for a MVDC link meshing MVAC distribution grids
No full textThis paper presents a protection scheme for a medium voltage dc (MVDC) link, that meshes three different MVAC distribution grids through ac/dc power converters. The proposed scheme includes active current limiters, hybrid circuit breakers and a communication layer for the coordination of these protection devices and power converters (logic selectivity). Active current limiters, installed just after dc bulk capacitors of each power converter, ensure fault current limitation in order to protect the power converters until the fault clearance by dc grid protections. The coordination logic among the protection devices is described in this paper, together with notes on the design of those devices. In case of communication failure, the proposed scheme could not guarantee logic selectivity, but it is anyway able to clear the fault. The effectiveness of the proposed protection strategy is validated in a fast transients simulation environment, using detailed model of power electronic converters
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
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
