Precios e iniciación de tabaquismo: el caso de Uruguay
Get PDFSe investigó el efecto del precio sobre la decisión de comenzar a fumar en Uruguay. El caso de Uruguay es interesante porque ha sido uno de los más activos en cuanto a políticas de control dentro del mundo. Se utilizaron datos transversales a partir de una encuesta nacional para los años 2014 y 2018 y análisis de supervivencia en tiempo discreto. Se encontró un efecto negativo y estadísticamente significativo del precio sobre la decisión de comenzar. También se encontró que el Convenio Marco para el Control del Tabaco tuvo un efecto significativo a la hora de postergar dicha decisión
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
Desnutrición crónica infantil y desigualdad socioeconómica en América Latina y el Caribe
Get PDFIncluye BibliografíaEn este trabajo se indaga acerca de los factores que determinanel nivel de desnutrición crónica infantil y su distribución socioeconómicaen ocho países de América Latina y el Caribe. Para ello se utiliza unametodología que permite descomponer un índice de desigualdadsocioeconómica (el índice de concentración); según los factores quelo afectan. En el caso de los países analizados, la "riqueza" de loshogares (medida mediante un indicador de bienestar material); y elnivel educativo de las madres son los determinantes más importantesde la distribución de dicha desnutrición. Los factores biomédicosconsiderados pueden ser relevantes para explicar el nivel de ladesnutrición, pero su contribución para explicar la desigualdad esrelativamente baja. Asimismo, factores geográficos, culturales, étnicose idiosincrásicos juegan un rol explicativo limitado y, aparentemente,lo hacen a partir de su relación con la distribución de las variablessocioeconómicas mencionadas
An agenda for action - transitioning to a healthy sustainable food system in Latin America
Get PDFThe project global objective was “to develop an integrated evidence-based agenda for action for healthy and sustainable food systems in Latin America that will prioritize healthy affordable diets, while keeping GHGs emissions within sustainable limits.” This objective was split into two sub-objectives: 1) to review the evidence on how to accelerate the transition to food systems that prioritize access to healthy affordable diets, while keeping GHGs emissions within sustainable limits; and 2) to analyze the underlying political economy that may prevent or enable rapid action. Though the scope of the project is Chile, there was a permanent coordination and dialogue with teams in Argentina (CEDES) and Brazil (IDEC). Problems were analyzed with a national focus but keeping in mind that there are common factors, challenges and actors that are present in the three countries (and probably in the region)
