Ensino superior: A última oportunidade para a promoção estruturada da atividade física?
No full textLivro de atas do 2.º Fórum REDESPP DESPORTO. REDESPP e Escola Superior de Educação e Ciências Sociais, Instituto Politécnico de Leiria.Diversos estudos analisam o declínio da prática atividade física (AF) e o aumento do sedentarismo e alertam para o facto de a inatividade ser um grave problema para a saúde. Os estudantes de Ensino Superior (ES) são um grupo de particular interesse porque, este grupo de adultos emergentes, são conhecidos por vivenciarem vários fatores de stress e de risco, durante a transição do ensino secundário para o ES. Os responsáveis de saúde reconhecem a importância de uma caracterização mais completa das características e comportamentos desta população específica para que se obtenha maior êxito nos progra-mas de prevenção e promoção da saúde. Objetivo: Investigar a relação entre a atividade física e a perceção da saúde dos estudantes de ensino superior
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
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
Programa de exercício para melhoria do equilíbrio: Protocolo de intervenção
Get PDFNTRODUCTION: With the increasing of age, neuromuscular deficits can result in impaired physical performance and increased risk of falls. Some intrinsic factors of falling risk, related to aging, are decreases in balance and strength performance, as well as cognitive decline (Gshwind et al., 2013). Balance is important to maintain posture and prevent falls. Specific balance exercises can help fight balance deficits and gait instabilities, reducing the risk of falls in older adults (Howe et al., 2011). However, more studies related to the prescription of physical exercise programs designed to improve the balance of the elderly are needed so that they can be easily implemented. PURPOSE: Evaluate the effects of a fall prevention program on balance and strength variables. Effects related to the detraining time will also be evaluated. METHODOLOGY: Older adults over 65 years of age, living in the community will participate in the study. The test protocol includes tests for static and dynamic balance assessment (Fullerton Advanced Balance Scale; Timed Up and Go Test;) and strength (T-Force Test); sociodemographic characterization questionnaires, fall history, physical activity (IPAQ - E), fear of falling (FES-I) and physical fitness assessment (Fullerton Functional Physical Fitness Battery). Participants will be randomly distributed into two groups, intervention group and control group. After the initial evaluations, participants in the intervention group will perform a specific balance and strength program, twice a week, for 12 weeks. Two intermediate evaluations will be performed at the 4th and 8th weeks. Subsequently, the effects of the detraining will be evaluated 4 and 8 weeks after the end of the program. The control group will not participate in any specific intervention during the trial period, continuing to receive the general physical activity program. However, they will receive the specific balance and strength program after the trial period. DISCUSSION/CONCLUSION: The combination of balance and strength training is expected to be effective in improving balance variables, lower limb strength and reducing the risk of falling. The results will have implications for the design and implementation of interventions to improve balance in the older adults. Information on the assessment of the risk of falling, dose-response relationships and distraining effects will also be provided. Finally, the professionals, responsible for the interventions, will receive an exercise program for the prevention of falls, easy to manage and scientifically validated
