Epidemiological study of sports injuries in basketball, futsal and volleyball among young athletes: aspects of training and clinical monitoring
No full textO objetivo deste estudo foi verificar a incidência das principais lesões esportivas comuns em atletas jovens de 16 a 19 anos de idade, que participaram de treinamento regular ou federado no ano de 2002, nas modalidades esportivas basquetebol, futsal e voleibol. Foram identificados, também, alguns aspectos de treinamento e estrutura médica. Para isso, aplicou-se um questionário para 323 atletas e entrevistas com 26 técnicos e 8 médicos, de 20 clubes esportivos de São Paulo. Os resultados do estudo indicaram um total de 343 lesões ou 1,7 lesão/atleta/ano. No basquetebol, as lesões mais comuns foram as entorses; a região corporal mais acometida de lesão foi a do tornozelo, seguida do joelho, coluna e dedos da mão; os armadores foram os mais afetados. No futsal, a lesão mais comum foi a entorse de tornozelo e houve ocorrência de lesão nas regiões da coxa e joelho; pivôs foram os mais afetados. No voleibol, a lesão mais comum foi a tendinite, principalmente na região do joelho, seguida das entorses e lesões musculares; a posição de meio de rede foi a mais afetada. As lesões ocorreram com uma maior freqüência em situações de treinamento. Dos 20 clubes avaliados, apenas oito possuem um médico especializado plantonista. Tal fato indica que alguns fatores de risco, como medidas preventivas em situações de treinamento, exame de pré-participação esportiva e acompanhamento médico especializado, não são devidamente organizados para os atletas jovens nos clubes avaliadosThe objective of this study was to evaluate the incidence of the main sports injuries commonly found in young athletes in the 16-19 year age group who participated in regular or federate trainings during 2002 in sports modalities such as basketball, futsal and volleyball. Also identified were some aspects of training and clinical structure. To obtain these data, a questionnaire was applied to 323 athletes and surveys were performed among 26 coaches and 8 physicians from 20 sports clubs located in Sao Paulo (Brazil). The results of the study showed a total of 343 injuries or 1.7 injury/athlete/year. In basketball, the most common injuries were sprains, the most affected body regions in terms of injury being the ankles, followed by knees, backbones and fingers; point guards being the most affected athletes. In futsal, the most common injuries were ankle sprains, the thigh and knee regions being also affected by injuries; pivots were the most affected among the team. In volleyball, the most common injury was tendonitis, mainly in the knee region, followed by sprains and muscle injuries; the most affected position being the forward-center\'s. The frequency of injuries was higher during trainings. Only eight of the 20 sports clubs evaluated actually hire specialized emergency physicians. This fact indicates that some risk factors such as preventive measures during trainings, sports preparation evaluation, and specialized clinical monitoring are not appropriately organized for young athletes in the assessed sports club

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
Influence of morphological, functional and psychological parameters on biochemistry, blood and immunological status of HIV/aids individuals
No full textEste estudo teve como objetivo analisar a influência de parâmetros morfológicos, funcionais e psicológicos no quadro bioquímico, sanguíneo e imunológico de indivíduos com HIV/aids. Para tanto, a amostra foi constituída por 41 voluntários infectados pelo HIV (25 66 anos de idade [x: 40,75 ± 8,68 anos]) do Ambulatório de Imunodeficiências Secundárias do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (ADEE 3002-HC-FMUSP). Os voluntários foram divididos em dois grupos de acordo com CD4+ nadir (< 200 cél·mm3 ou > 200 cél·mm3). Foram mensuradas as variáveis composição corporal, parâmetros neuromusculares e cardiorespiratórios, capacidade funcional, qualidade de vida, atividade física, satisfação sexual, sintomas depressivos assim como parâmetros bioquímicos, sanguíneos e imunológicos. Foram observadas diferenças estatisticamente significativas entre os grupos somente para o teste velocidade máxima de caminhada, colesterol total, LDL e CD4+ nadir (p<0,05). Houve tendência de os voluntários localizados no grupo CD4+ nadir < 200 cél·mm3 apresentarem maior associação nas variáveis composição corporal, parâmetros neuromusculares e cardiorespiratórios, capacidade funcional, qualidade de vida, atividade física, satisfação sexual e sintomas depressivos sobre o quadro bioquímico, sanguíneo e imunológico. Os resultados deste estudo permitem concluir que a composição corporal, parâmetros neuromusculares e cardiorespiratórios, capacidade funcional, qualidade de vida, atividade física, satisfação sexual e os sintomas depressivos não se associam fortemente com o quadro bioquímico, sanguíneo e imunológico de indivíduos infectados pelo HIV independente do histórico clínico pregresso. Por outro lado, existe interdependência entre as diferentes características acima descritas nos diferentes grupos para CD4+ nadir (< 200 cél·mm3 e > 200 cél·mm3), sobretudo, para aqueles voluntários localizados no grupo CD4+ nadir < 200 cél·mm3The purpose of this study was to analyze the influence of morphological, functional and psychological parameters on biochemistry, blood and immunological status of HIV/aids individuals. Sample was constituted by 41 HIV infected men individuals (25 66 year-old [x: 40.75 ± 8.68 years]) of the Secondary Immunodeficiency Ambulatory from Hospital das Clínicas Faculty of Medicine, USP (ADEE 3002-HC-FMUSP). Volunteers were agrouped into two groups according to the CD4+ nadir (< 200 cell·mm3 or > 200 cell·mm3). The variables measured were body composition, cardiorespiratory and neuromuscular parameters, functional capacity, quality of life, physical activity, sexual satisfaction, depressive symptoms, as well as biochemical, blood and immunological parameters. There were statistically significant differences between the groups only for maximum walking velocity, total cholesterol, LDL and CD4+ nadir (p<0.05). There was tendency of the volunteers in the group CD4+ nadir < 200 cell·mm3 to show more prevalence and higher significant correlation values in the association among body composition, neuromuscular and cardiorespiratory parameters, functional capacity, quality of life, physical activity, sexual satisfaction and depressive symptoms and biochemical, blood and immunological parameters. The data permite to conclude that there was not strongly association among body composition, neuromuscular and cardiorespiratory parameters, functional capacity, quality of life, physical activity, sexual satisfaction and depressive symptoms, and biochemical, blood and immunological parameters regardless of historical clinical status. On the other hand, it was observed the existence of an interdependence phenomenon among the previously described different characteristics in the distint groups to CD4+ nadir (< 200 cell·mm3 and > 200 cell·mm3), specially, for the volunteers of the CD4+ nadir < 200 cell·mm
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
