Generalidades de la sarcopenia y su tratamiento a través del entrenamiento de la fuerza
Full text linkAs a geriatric syndrome, sarcopenia is characterized by progressive, generalized loss and functional decline of skeletal muscles. It has an essential role in the pathogenesis of frailty in advanced ages, low muscle strength is its main parameter. This review aims to present some of its general characteristics, as well as the main benefits and peculiarities of strength training to prevent or counteract it. For this, a bibliographic search was carried out in databases such as Pubmed and SciELO, the Google Scholar search engine was obtained, reviewing 105 documents, of which 25 were referenced.Como síndrome geriátrico la sarcopenia se caracteriza por pérdida progresiva, generalizada y disminución funcional de la musculatura esquelética. Tiene un papel esencial en la patogénesis de la fragilidad en edades avanzadas, la baja fuerza muscular es su parámetro principal. En esta revisión se pretende exponer algunas de sus características generales, así como los principales beneficios y peculiaridades del entrenamiento de la fuerza para prevenirla o contrarrestarla. Para ello se realizó una búsqueda bibliográfica en bases de datos como Pubmed y SciELO, se utilizó el motor de búsqueda de Google Scholar, revisando 105 documentos, de los cuales 25 fueron referenciados
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
La práctica del yang shi taijiquan y sus beneficios en la condición física funcional de mujeres entre 60 y 69 años de edad.
No full textLa investigación tuvo como objetivo evaluar los cambios en la condición
física funcional que produce la práctica de métodos terapéuticos chinos en un
grupo de mujeres con edades entre 60 y 69 años, quienes realizan ejercicios físicos
en el círculo de abuelos “José María Queralt”, perteneciente a la Facultad de
Cultura Física de la Universidad de Guantánamo. El estudio se dividió en cuatro
fases (comprendido entre el período de septiembre 2018 y mayo 2019). Para evaluar
la condición física funcional se utilizó el Senior Fitness Test (SFT); se trabajó con la
estadística inferencial, se utilizó Wilcoxon a un nivel de confianza del 95% y se
procesaron los datos a través del paquete estadístico SPSS versión 21.0 para
Windows, y el Excel. Los resultados arrojaron una mejoría significativa en los
componentes de la condición física funcional en la población estudiada, con
excepción del índice de masa corporal (IMC)
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
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
