Componente social y de sostenibilidad
No full textEn la actualidad, la industria minera, consciente de la importancia de un sólido relacionamiento con todos sus grupos de interés (stakeholders) aplica a sus procesos estándares internacionales en materia de sostenibilidad, suministro responsable y buenas prácticas, que son necesarios para un adecuado desempeño social, empresarial, ambiental y de relacionamiento institucional. Estos estándares y buenas prácticas son estudiados en este módulo con una visión holística desde cada una de las actividades propias de su cadena de valor.
Contenido: 1. Relación entre el principio de estado unitario y el principio de autonomía en el sector minero, 2. Evolución jurisprudencial en la interpretación y aplicación del principio de estado unitario y el principio de autonomía en el sector minero, 3. Relación con las autoridades locales y comunidades a partir de la unificación jurisprudencial, 4. El concepto de licencia social para operar.
El sector minero es consciente de desarrollar sus actividades con un enfoque de sostenibilidad ambiental, pero también la sostenibilidad se predica del relacionamiento con las comunidades, con las autoridades locales y de la aplicación de los más altos estándares internacionales en materia de sostenibilidad en las diversas etapas de su cadena de valor. La jurisprudencia de la Corte Constitucional ha marcado las pautas para este nuevo criterio de relacionamiento social y territorial, decisiones y tendencias doctrinales que se abordan en este módulo, los cuales contribuyen a la búsqueda y consolidación de la licencia social para operar.
Contenido: 1. El Desarrollo Sostenible, 2. El Nuevo Contexto de los Negocios, 3. Situación y perspectivas del sector minero frente a la sostenibilidad.En este curso de 3 horas de duración el estudiante aprenderá sobre dos módulos que trataran desde lo social y lo sostenible el sector minero
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
Kinetic Sunyaev–Zel’dovich effect in rotating galaxy clusters from MUSIC simulations
No full textThe masses of galaxy clusters are a key tool to constrain cosmology through
the physics of large-scale structure formation and accretion. Mass estimates
based on X-ray and Sunyaev--Zel'dovich measurements have been found to be
affected by the contribution of non-thermal pressure components, due e.g. to
kinetic gas energy. The characterization of possible ordered motions (e.g.
rotation) of the intra-cluster medium could be important to recover cluster
masses accurately. We update the study of gas rotation in clusters through the
maps of the kinetic Sunyaev--Zel'dovich effect, using a large sample of massive
synthetic galaxy clusters (M at
) from MUSIC high-resolution simulations. We select few relaxed objects
showing peculiar rotational features, as outlined in a companion work. To
verify whether it is possible to reconstruct the expected radial profile of the
rotational velocity, we fit the maps to a theoretical model accounting for a
specific rotational law, referred as the vp2b model. We find that our procedure
allows to recover the parameters describing the gas rotational velocity profile
within two standard deviations, both with and without accounting for the bulk
velocity of the cluster. The amplitude of the temperature distortion produced
by the rotation is consistent with theoretical estimates found in the
literature, and it is of the order of 23 per cent of the maximum signal
produced by the cluster bulk motion. We also recover the bulk velocity
projected on the line of sight consistently with the simulation true value
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
