La inserción del vino argentino en el mercado mundial entre 1980 y 2019: características, comportamientos y factores asociados
No full textEste trabajo analiza el desarrollo de las exportaciones de vino argentino desde 1980 hasta 2019, centrándose en la evolución del tipo de cambio y las políticas macroeconómicas, y la dinámica de los mercados receptores. La hipótesis principal plantea que las exportaciones se convirtieron en una salida para el sector vitivinícola argentino en medio de la crisis más importante que tuvo que atravesar el sector durante todo el siglo XX. Esto condujo a transformaciones profundas y a la puesta en marcha de una nueva estrategia de desarrollo sectorial. La investigación se basa fundamentalmente en fuentes cuantitativas proporcionadas por el Instituto Nacional de Vitivinicultura, la Bolsa de Comercio de Mendoza y la Organización Internacional de la Viña y el Vino.Fil: Cerdá, Juan Manuel.

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
Costs of wine making : Case study according to the size of the winery and market (Mendoza, Argentina)
Full text linkDespués de 20 años de crecimiento, el sector vitivinícola argentino ha comenzado una pérdida constante competitividad. Se identifican diversos tipos de causas pero las económicas predominan en la mente de las empresas al momento de enunciar sus principales problemas, siendo el más identificado el aumento de costos, tanto en producción de uvas como en elaboración de vinos, aunque en el resto de la cadena también se hacen sentir. La evolución de la rentabilidad de las bodegas como su sustentabilidad depende directamente del impacto que tenga su estructura de costos. SE aplica el concepto de sustentabilidad que abarca aspectos económicos, ambientales y sociales. Entonces, conocer los factores de costos y su influencia será clave. El problema detectado en bodegas es la imposibilidad de contar con información concreta que identifique los factores relevantes de costos, describa su comportamiento y el grado de influencia y por ende genere acciones para disminuirlos. Se trabaja con la hipótesis de que al conocer el comportamiento de los factores, se dispondrá de información que permita la reducción de costos, mejorando el perfil competitivo y de sustentabilidad de la empresa. El objetivo es cuantificar los costos de elaboración de vinos representativos para las bodegas de Mendoza. Específicamente se busca identificar casos representativos por tamaño y nivel cualitativo, sus factores de generación de costos y describir su comportamiento e influencia en para poder proponer indicadores para monitorear su comportamiento y evolución. La población objetivo serán las empresas vitivinícolas de Mendoza, segmentadas por tamaño y mercado dentro de las que se realizaran los estudios de casos representativos por zona:: la unidad de análisis será la línea de elaboración de vinos, identificando como variables independientes a las actividades que se desarrollan para obtener cada tipo de producto. En el cálculo de costos se usará metodología de costeo basado en actividades (Activity Based Costing). Para la identificación de indicadores relevantes se trabajarán con referentes del sector mediante entrevistas e instalación puntos de toma de datos. Los resultados a obtener son: costos de elaboración de productos vínicos por tipo y destino e, indicadores de desempeño. Los beneficiarios directos son bodegueros, organizaciones gubernamentales, empresariales y sectoriales. Se obtendrá información relevante para la aplicación directa en actividades académicas, de formación y extensión.After 20 years of growth, the Argentine wine sector has begun a constant loss of competitiveness. Different types of causes are identified but the economic ones predominate in the mind of the companies when enunciating their main problems, the most identified being the increase in costs, both in grape production and wine making, although in the rest of the chain are also felt. The evolution of the profitability of wineries as their sustainability depends directly on the impact of their cost structure. The concept of sustainability that covers economic, environmental and social aspects is applied. Then, knowing the cost factors and their influence will be key. The problem detected in wineries is the impossibility of having specific information that identifies the relevant factors of costs, describe their behavior and the degree of influence and therefore generate actions to reduce them. We work with the hypothesis that by knowing the behavior of the factors, information will be available to reduce costs, improving the competitive profile and sustainability of the company. The objective is to quantify the costs of making representative wines for Mendoza wineries. Specifically, it seeks to identify representative cases by size and qualitative level, their factors of cost generation and describe their behavior and influence in order to propose indicators to monitor their behavior and evolution. The target population will be the wine companies of Mendoza, segmented by size and market within which the representative case studies will be carried out by area: the unit of analysis will be the wine production line, identifying as independent variables the activities that they are developed to obtain each type of product. Activity Based Costing will be used in the calculation of costs. To identify relevant indicators, we will work with industry leaders through interviews and installation of data collection points. The results to obtain are: costs of elaboration of wine products by type and destination, and performance indicators. The direct beneficiaries are winemakers, governmental, business and sectoral organizations. Relevant information will be obtained for direct application in academic, training and extension activities
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
