    Most of the world's population is concentrated in cities and there is necessary to intervene in the management of energy consumptions to ensure a high quality of people life with good air quality and thermal comfort and an overall livability of the urban environment. Anthropic activities are the main cause of greenhouse gas emissions and this suggests the need of a different management of energy consumptions especially of buildings, one of the principal contributor of GHG emissions. The goal of this work is the evaluation of a simplified energy model that allows quantifying the spatial distribution of energy consumption at urban scale with a GIS tool. The case study is the metropolitan area of Gran Mendoza, an urban conglomerate comprising six departamentos in the central-western region of Argentina. The model estimates the energy consumption for space heating of residential buildings, after having classified the buildings according to their characteristics. This simplified model has been validated by the comparison with the real consumption data provided by the local company distributing natural gas. With this model, it is possible to elaborate energy strategies based on the real buildings heritage, identifying critical areas requiring a priority of intervention

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    El consumo de la energía en la edificación se ve incrementado por el aumento de la población urbana, la fuerte expansión de las ciudades y las actividades antropogénicas, especialmente en los países en desarrollo, siendo principalmente dependiente de las condiciones del clima urbano y de la morfología urbano-edilicia. El estudio tiene como objetivo profundizar el conocimiento de las variables forma y orientación de las manzanas urbanas ya que las mismas intervienen en el potencial solar de entornos urbanos típicos del área metropolitana de Mendoza (AMM), condicionando la posibilidad de utilizar estrategias de diseño bioclimático y limitando la posibilidad de acceso a los recursos que ofrece el clima en distintas épocas del año.Metodológicamente, se calculó la orientación del eje principal para la totalidad de las manzanas urbanas del AMM, en sistemas de información geográfica (SIG), y de su forma como proporción de lados de las unidades predominantemente rectangulares, lo que permitieron obtener resultados y desarrollar modelos estadísticos. Los resultados presentan limitaciones propias relacionadas con la orientación principalmente en áreas de crecimiento y densificación urbana que están llevando a una situación crítica tanto en lo ambiental como en lo energético. La investigación permitirá a futuro identificar e implementar propuestas de crecimiento y renovación urbana indispensables para una aproximación a la consecución de la sostenibilidad ambiental y energética del tejido urbano, definiendo lineamientos y estrategias.The energy consumption in the building is increased by the increase of the urban population, the strong expansion of cities and anthropogenic activities, especially in developing countries, being mainly dependent on the conditions of the urban climate and morphology urbanedilicia. The study aims to deepen the knowledge of the variables urban form and orientation since it intervenes in the solar potential of urban environments typical of the metropolitan area of Mendoza (AMM), conditioning the possibility of using bioclimatic design strategies and limiting the possibility of access to the resources offered by the climate at different times of the year. Methodologically, the orientation of the main axis for all the buildings constructed for the urban blocks of the AMM and its shape (as a proportion of sides of the predominantly rectangularunits) was calculated, using the geographic information systems (GIS). These informations allowed obtaining results and developing statistical models. The results present own limitations related to the orientation mainly in the areas of urban growth and densification that are leading to a critical situation both environmentally and energyly. The research will allow the future to identify and implement proposals for urban growth and renewal that are essential for an approach to the achievement of the environmental and energy sustainability of the urban fabric, defining guidelines and strategiesFil: Arboit, Mariela Edith.

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    We 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

    We 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
