Tipo de estudo : estudo anatomico Descritiva. Metodo: Trinta joelhos foram dissecados por meio de uma via de acesso posterior ao joelho. A presenca do ligamento popliteo posterior e do ligamento meniscofemoral Wrisberg foram observados e capsulotomia forma de U foi realizada , ao mesmo tempo preservando a insercao distai . Depois de retirar o ligamento cruzado posterior e determinacao da sua area sobre a tibia , o seu centro geometrico e margem posterior foram determinados e as distancias entre a insercao tibial da capsula e estes pontos foram medidos. Resultados: A distancia entre o centro do ligamento cruzado posterior e a capsula posterior era de 10,3 mm e a distancia entre a margem posterior do ligamento cruzado posterior e da capsula foi de 1,6 mm. O ligamento popliteo posterior era facil de ver em todas as amostras , medindo cerca de 42 mm de comprimento. O ligamento Wrisberg foi observado em 12 especimens. Conclusao: As distancias da insercao tibial da capsula para o centro da insercao do ligamento cruzado posterior e sua margem posterior foram de 10,3 mm e de 1,6 mm, respectivamente. O conhecimento da anatomia da regiao posterior do joelho e importante no planeamento de cirurgia segura nesta regiao do joelho , em especial nos casos de reconstrucao do ligamento cruzado posteriorBV UNIFESP: Teses e dissertaçõe
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
Efeito crônico da autoliberação miofacial comparado com alongamento estático na amplitude de movimento de tornozelo
No full textStatic stretching and myofascial self-release exercises are described to improve short-term range of motion results for muscle shortening patients. However, no study has compared static stretching with myofascial self-releasing exercise after eight weeks of intervention. Objective: To compare the effect of static stretching with myofascial self-release technique in ankle dorsiflexion range of motion in street runners. Design: Randomized Clinical Trial. Methods: A single center study of runners with ankle plantar flexors. Runners were randomized to a group of patients who performed passive stretches of plantar ankle flexors three times a week for eight weeks, or a myofascial self-roll group at home. The primary outcome was ankle ROM at eight weeks and 12 weeks. The secondary outcome was treatment adherence. Results: Nineteen athletes were randomly allocated to the static stretching group and 21 participants to the myofascial self-releasing group. Compared with the myofascial self-releasing group, the static stretching group had a minimal statistically important difference in ankle dorsiflexion range of motion with a difference in the percentage between groups [95% confidence interval], (14.3% [1, 52 to 7.98], p = 0.01) at eight weeks and (11.6% [0.69 to 6.99], p = 0.01) at 12 weeks after the start of the intervention. Adherence to intervention was considered high, with 91%. Conclusions: Supervised static stretching of the ankle plantar flexors resulted in significant mid-term improvements (8 and 12 weeks after the start of the intervention) in ankle dorsiflexion range of motion compared with self-release technique.Exercícios de alongamento estático e autoliberação miofascial são utilizados para aumentar a amplitude de movimento a curto prazo para pacientes com encurtamento muscular. No entanto, nenhum estudo comparou o alongamento estático com exercício de autoliberação miofascial após 8 semanas de intervenção. Objetivo: Comparar o efeito do alongamento estático com a técnica de autoliberação miofascial na amplitude de movimento de dorsiflexão de tornozelo em corredores de rua. Métodos: Um ensaio clínico aleatorizado e de centro único, com corredores de rua sem lesões em membros inferiores nos últimos 6 meses. Os corredores foram aleatorizados para um grupo de pacientes que realizavam alongamentos passivos de flexores plantares de tornozelo, três vezes por semanas durante oito semanas, ou um grupo de autoliberação miofascial com rolo em casa. O desfecho primário foi a amplitude de movimento de tornozelo em oito semanas e 12 semanas. O desfecho secundário foi adesão ao tratamento. Resultados: Dezenove atletas foram alocados aleatoriamente no grupo alongamento estático e 21 participantes no grupo autoliberação miofascial. Comparado com o grupo autoliberação miofascial, o grupo alongamento estático teve uma diferença estatisticamente importante mínima na amplitude de movimento de dorsiflexão de tornozelo com uma diferença na porcentagem entre os grupos [intervalo de confiança de 95%], (14,3% [1,52 a 7,98], p = 0,01) em oito semanas e (11,6% [0,69 a 6,99], p = 0,01) com 12 semanas após o início da intervenção. A adesão à intervenção foi considerada alta, com 91%. Conclusões: O alongamento estático do músculo tríceps sural resultou em melhorias significativas a médio prazo (8 e 12 semanas após o início da intervenção) na amplitude de movimento de dorsiflexão de tornozelo em comparação com o exercício de autoliberação.Dados abertos - Sucupira - Teses e dissertações (2020
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
