Problematizar los bosques nativos de la geografía escolar : Hacia la construcción de una mirada crítica
Get PDFLas problemáticas ambientales, analizadas desde una mirada compleja y multidimensional, es una estrategia que sitúa al alumno en una educación globalizadora. La finalidad del proyecto de aprendizaje basado en problemas, se inserta en fortalecer capacidades y desarrollar un pensamiento crítico a través de actividades de reflexión y de argumentación, que contribuyan al desarrollo de acciones y compromiso ciudadano con el entorno ambiental. En este contexto, la siguiente secuencia didáctica plantea analizar la deforestación de los bosques nativos de la Región Chaqueña en Argentina, propiciando la incorporación de valores ambientales y fomentar una actitud crítica a la vez que constructiva. Para ello se utilizó datos de una encuesta realizada en la comunidad educativa de la Escuela Secundaria Nº 20 de Tandil, a docentes, auxiliares, alumnos y familiares. Entre las conclusiones se resalta que si bien la mayoría conocían las causas de la deforestación, desconocían el logo de certificación de los bosques de manera sustentable. Es a partir de ello que el producto final es la elaboración de un folleto de concientización y divulgación que está vinculado con información sobre un logo de certificación ambiental de los bosques; y de esta manera promover el uso ambientalmente responsable, socialmente benéfico y económicamente viable de los bosques del mundo.Fil: Pascuzzo, Marisa.

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
El gas como recurso geoestratégico en Argentina
Get PDFLos recursos energéticos son fundamentales para sostener la vida del planeta y poner en funcionamiento las actividades productivas. En la actualidad, hay una gran dependencia de los combustibles fósiles, cuyas reservas están casi agotadas. La humanidad enfrenta hoy un problema acuciante, ya que el consumo de energía continua aumentando aceleradamente. El aumento de la población, el desarrollo económico, los avances tecnológicos son los factores que producen el aumento del consumo de energía.
El gas natural es la segunda fuente de energía de mayor utilización después del petróleo, por ello en el presente trabajo se propone analizar la situación de Argentina en relación al consumo y a las reservas disponibles, como así también los inconvenientes que presenta el abastecimiento de nuestro país con respecto al gas. Desde una visión geoestratégica se analizará la situación argentina con respecto al recurso gasífero y si existe equilibrio entre la demanda social y la oferta ambiental. Se tomará en cuenta que el espacio geográfico producto de la relación entre la sociedad y la naturaleza se construye históricamente y se va modificando en forma permanente, pues las sociedades cambian en el tiempo y las condiciones naturales también lo hacen.Instituto de Relaciones Internacionales (IRI
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
