Residuos, una imagen crónica en esquinas del Área Metropolitana de Buenos Aires
Get PDFEl aumento en la generación del volumen de residuos sólidos urbanos (RSU) en las grandes urbes y su gestión inadecuada resultan muchas veces en la conversión de los espacios públicos en microbasurales. El objetivo del presente trabajo es analizar la generación de RSU y su disposición en espacios públicos de la localidad de González Catán (partido de La Matanza, provincia de Buenos Aires). Se utilizaron métodos cualitativos y cuantitativos tales como entrevistas a actores clave y encuestas mediante una técnica de tipo discrecional (“bola de nieve”) y se realizaron relevamientos a escala microlocal para la identificación de microbasurales. Utilizando el software QGIS 3.10.14 with GRASS 7.8.5 y Google Earth Pro se elaboraron mapas temáticos que describen la problemática. A partir del análisis de las encuestas (n=202) se detectó que el 62% de los encuestados desconocían aspectos relacionados a la segregación de residuos en los domicilios, mientras que un 57% reconoció la falta de participación ciudadana en la gestión ambiental. Simultáneamente, entre los meses de abril del 2020 y mayo del 2021 se detectó un incremento del 25% en el número de microbasurales relevados. Los esfuerzos por erradicar estos microbasurales han sido infructuosos, por lo tanto, se requiere un trabajo interdisciplinario a fin de lograr la rehabilitación socioambiental de los espacios públicos afectados por esta problemática.Fil: Brito, Marcos.

Residuos, una imagen crónica en esquinas del Área Metropolitana de Buenos Aires
No full textLos microbasurales en González Catán constituyen un grave problema ambiental y sanitario. Se trata de áreas donde se acumula basura de manera incorrecta, sin seguir las normas de eliminación adecuada. Esto contamina el suelo, el agua y el aire, y se afecta la calidad de vida de los residentes. La falta de conciencia ambiental y de sistemas deficientes de gestión de residuos sólidos contribuye a su formación, junto a prácticas inadecuadas de disposición de residuos y factores socioeconómicos. Este trabajo tiene como objetivo caracterizar la gestión de los residuos sólidos urbanos (RSU) en González Catán, con enfoque en la existencia de microbasurales. Se busca comprender su génesis, características e impactos ambientales y proponer estrategias efectivas de gestión y mitigación. Para ello se utilizó un enfoque cualitativo y cuantitativo, mediante observación directa, entrevistas semi estructuradas y encuestas. Entre abril de 2020 y mayo de 2021, se entrevistó a actores de diversas áreas, incluyendo educación, comunidades y organizaciones ambientales. Los resultados del relevamiento, encuestas y entrevistas muestran que la falta de gestión adecuada de los residuos sólidos urbanos tiene un impacto negativo en el entorno, lo que preocupa a los vecinos. La percepción generalizada de que la acumulación de basura es una parte normal del paisaje diario destaca que es imperativo aumentar la conciencia y educación ambiental para cambiar esta actitud. El desempleo lleva a muchos a buscar materiales reciclables en los microbasurales para vender, lo que sugiere que abordar el problema de los microbasurales no solo tiene implicaciones ambientales, sino también sociales y podría requerir estrategias integrales de desarrollo económico y empleo. Ante esta problemática creciente, el incumplimiento de la legislación existente y la necesidad de mejoras se dan recomendaciones para controlar y prevenir los microbasurales.Fil: Brito, Marcos.

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
