Get PDFEl Posgrado en Aprovechamiento de Recursos Hidráulicos de la Facultad de Minas de la Universidad Nacional de Colombia. Sede Medellín. cumplió el pasado mes de Agosto 25 años de actividad académica continua, razón por la cual la revista, ventana de divulgación de la producción científica del posgrado, se une a esta importante efemérides mediante el lanzamiento de este número. Adicionalmente a los artículos que nuestros colaboradores nos hicieron llegar y que orgullosamente publicamos, hemos incluido en este número especial dos artículos que se relacionan directamente con la efemérides del Posgrado. En el primer artículo se presenta de una manera detallada la producción científica del Posgrado en estos 25 años, producción representada por las tesis de los estudiantes de Maestría y de Doctorado y por los artículos científicos publicados por los estudiantes y profesores. Se podrá observar la evolución que han tenido las diferentes áreas del investigación del Posgrado e inferir sus potencialidades futuras. En un número posterior les presentaremos un resumen de las actividades de extensión realizadas por el Posgrado, actividades que de todas maneras han tenido su componente investiga: i va El segundo artículo corresponde al discurso del Profesor Darío Valencia Restrepo, fundador del Posgrado, en el acto de otorgamiento que le hizo la Universidad Nacional de Colombia del Doctorado Honoris Causa el pasado mes de Octubre en la ciudad de Bogotá. El lector podrá reconocer la importancia que el Dr. Valencia le da a la preparación Integra) que debe tener todo egresado de la Universidad, importancia que ha mantenido y divulgado durante toda su vida académica. Finalmente, renovamos nuestro llamamiento a la comunidad científica nacional e internacional para que utilicen la Revista Avances en Recursos Hidráulicos como el medio de divulgación de sus actividades de investigación
Acción fotográfica para el recuerdo: Fotografías de Mauricio Toro Goya. Ficha de observación de fotografía_Nº1
Get PDFFicha Observación de Fotografía Contemporánea. Apoyo a la docencia.A través de la observación del trabajo del fotógrafo chileno Mauricio Toro Goya, quiero abrir la reflexión sobre las diferentes formas de expresión de la fotografía en relación a la memoria traumática a través del acto performativo.
Las fotografías de Toro Goya se inscriben en lo que denominamos una acción fotográfica para el recuerdo, donde la fotografía requiere de una puesta en escena para su realización.
En este análisis quiero evidenciar el fuerte compromiso del artista con la memoria traumática que ha dejado la violencia en su territorio. Violencia que ha desbordado la fotografía de su ámbito documental y estético y la ha desplazado como herramienta de comunicación afectiva a través de un acto fotográfico que escenifica de diferentes maneras el horror de la desaparición y la magnitud de la falta.
Estos actos fotográficos promueven diferentes maneras de empatía con el espectador y buscan no sólo la liberación de un dolor personal sino el encuentro de toda una colectividad que ha quedado en un duelo suspendido
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
Reporte Técnico - compresión imágenes aplicado - Tomas Gaviria - David Ruiz - Simón Marín - Mauricio toro
No full textOn this occasion, the problem being addressed is how we can through an image compression and decompression algorithm help traditional livestock farming. It is important because farmers handle this information in an inefficient way such as using notebooks, so giving them a new way for this would make their work much more enjoyable. One of the major drawbacks is that this software must be economical to support, in terms of energy and memory space because the field does not have the best performance for energy and computer systems. The algorithm that was finally used was the Huffman, this algorithm allows in time a fast response
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
