Riesgo cardiovascular en pacientes hipertensos atendidos en la consulta externa de cardiología hospital iess – riobamba en el período de enero - junio del 2013."
Get PDFLas enfermedades cardiovasculares actualmente han obtenido mayor interés dentro del campo de la medicina debido a su alta incidencia y prevalencia, según el estudio INTERHEART América Latina registra una de las tasas de infarto más altas a nivel mundial, por tal motivo nuestro trabajo pretendió determinar el riesgo cardiovascular en pacientes Hipertensos que acuden al servicio de Consulta Externa de Cardiología en el Hospital IESS- Riobamba en el período de Enero a Junio del 2013. El tipo de estudio que se realizó fue descriptivo, retrospectivo, de corte trasversal, se realizó en el área de Consulta Externa de Cardiología, se utilizó como instrumento determinante el Score de Framingham que mide la probabilidad estimada para desarrollar enfermedad coronaria.UNACH,Sede Ecuado
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
Riesgo cardiovascular en pacientes hipertensos atendidos en la consulta externa de cardiología. Hospital IESS-Riobamba. Enero-junio 2013
No full textAn observational, descriptive, cross-sectional researching process with a mixed approach was carried out in order to characterize the cardiovascular risk factors in hypertensive patients treated in the outpatient cardiology clinic of IESS (Ecuadorian Social Security Institute) Hospital, Riobamba, in the period of January-June, 2013. A sample of 1256 according to different criteria was selected from a population study of 3889. The respective data were collected by reviewing documents through the corresponding guide-designed. The female sex predominated in the research environment with 60.0%, as well as ages over 65. The sedentary lifestyle was the main risk factor present with 66.98% of incidence. The majority of the sample studied was classified as having a low cardiovascular risk of 74% and only 6.06% was classified as very high to suffer this disease during the following 10 years.Se realizó un proceso investigativo observacional descriptivo, de corte transversal, con enfoque mixto; con el propósito de caracterizar los factores de riesgo cardiovascular en pacientes hipertensos atendidos en la consulta externa de cardiología Hospital IESS- Riobamba, en el periodo de enero-junio, 2013. La población de estudio estuvo constituida por 3889 individuos, de la cual se seleccionó una muestra de 1256 atendiendo a diferentes criterios. Los respectivos datos se recolectaron mediante la revisión de documentos, para lo cual se diseñó la correspondiente guía. En el entorno de investigación predominó el sexo femenino, para un 60,0 %; así como las edades mayores de 65 años. El sedentarismo resultó el principal factor de riesgo presente con un 66.98 % de incidencia. La mayoría de la muestra estudiada se catalogó como de bajo riesgo cardiovascular 74 % y solo el 6,06 % se enmarcó en la categoría de muy alto a sufrir esa enfermedad durante los 10 años siguientes
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
