Association between walkability and body mass index of children and adolescents in the city of Medellín, 2023
No full textRESUMEN: Medellín, como epicentro urbano del Valle de Aburrá, enfrenta el desafío de equilibrar un rápido desarrollo urbano con la calidad de vida de sus habitantes. En este contexto, la transitabilidad del entorno emerge como un factor clave que conecta el diseño urbano con la salud, especialmente niños en y adolescentes. Este estudio se centró en evaluar cómo las características del entorno, como la densidad residencial, intersecciones y acceso a espacios verdes, se asocian con el índice de masa corporal (IMC) de esta población. Objetivo: Analizar la relación entre la transitabilidad del entorno urbano y el IMC en niños, niñas y adolescentes de Medellín, para generar evidencia que pueda guiar políticas urbanas públicas y de salud. Metodología: Se empleó un diseño transversal con datos secundarios del estudio del Perfil Alimentario y Nutricional de Antioquia 2023. Se integraron datos sociodemográficos, antropométricos y variables del entorno urbano obtenidos de bases de datos municipales y herramientas SIG. Se calculó un índice de transitabilidad a partir de densidad residencial, intersecciones y acceso a zonas verdes, utilizando radios de 500 metros y 1 kilómetro alrededor de los hogares de los participantes. Resultados: Se identificaron diferencias en el acceso a variables ambientales por sexo. Los hombres mostraron una mayor variabilidad en la densidad residencial y NDVI, mientras que las mujeres mostraron valores más consistentes. El índice de transitabilidad osciló entre -10,24 y 6,51 para hombres y -9,43 y 5,85 para mujeres. Los espacios deportivos y zonas verdes se distribuyen equitativamente en una radio de 500 m, pero las distancias y la accesibilidad varían. Se observaron correlaciones significativas entre el IMC y variables como densidad de intersecciones y accesibilidad a zonas verdes.
Conclusiones: La transitabilidad urbana influye en el estado nutricional de niños y adolescentes, destacando la importancia de diseñar entornos urbanos que promuevan la movilidad activa y el acceso a espacios verdes. Este estudio resalta la necesidad de políticas urbanas que fomenten la actividad física y reduzcan el factorCOL0004362MaestríaMagíster en Epidemiologí
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
Efectos del entrenamiento de la fuerza en personas con Diabetes Mellitus tipo 2: Revisión sistemática
No full textLa Diabetes Mellitus es una enfermedad causada por la deficiencia en el metabolismo de la glucosa y también por la baja sensibilidad de la hormona insulina, esta afecta cerca de 478 millones de personas en el mundo. Las ciencias del Deporte y la Salud han venido desempeñando investigaciones de los efectos del ejercicio en personas que presenten DM2 y cuáles deberían ser los parámetros para la práctica. La búsqueda sistemática realizada en las bases de datos Embase, Pubmed, Scopus; tuvo como objetivo los estudios referentes al entrenamiento de la fuerza en personas con DM2, que evaluaron parámetros como Hba1c, Insulina, Ldl-c, Hdl-c, Triglicéridos. Luego de la recopilación y cribado de los estudios, fueron incluidos 7 artículos que cumplían con todos los términos de inclusión establecidos, resaltando que el entrenamiento de la fuerza se puede evidenciar mejoras en variables como: Homa-IR; P<0.05, ldl-c, P<0.05, Hdl-c; P<0.05, glucosa, P<.0001.Diabetes Mellitus is a disease caused by deficiency in glucose metabolism and also by low sensitivity of the hormone insulin, which affects about 478 million people in the world. Sports and Health sciences have been conducting research on the effects of exercise in people with DM2 and what the parameters for practice should be. The systematic search carried out in the databases Embase, Pubmed, Scopus; focused on studies related to strength training in people with DM2, which evaluated parameters such as Hba1c, Insulin, Ldl-c, Hdl-c, Triglycerides. After the compilation and screening of the studies, 7 articles were included that fulfilled all the established parameters, being able to highlight that through resistance training improvements are evidenced in parameters such as: Homa-IR; P <0.05, ldl-c, P <0.05, Hdl-c; P <0.05, glucose, P<.0001

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
