Adaptação cultural para o português falado no Brasil do SNOT-22: um instrumento doença-específico de avaliação de qualidade de vida em pacientes com afecções nasossinusais
Full text linkDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde. Programa de Pós-Graduação em Ciências MédicasIntrodução: A rinossinusite apresenta alta prevalência, gera gastos vultosos e o seu impacto vem sendo demonstrado por questionários genéricos de qualidade de vida. Todavia, instrumentos genéricos podem não detectar efeito de intervenções e tratamentos. O SNOT-22 figura entre os principais instrumentos doença-específico na avaliação da qualidade de vida dos pacientes com rinossinusite. Contudo, não existe versão validada deste questionário no Brasil. Objetivo: Adaptar culturalmente para o português falado no Brasil o SNOT-22 e avaliar suas propriedades psicométricas. Materiais e métodos: A versão em português foi desenvolvida obedecendo à robusta metodologia preconizada pela literatura e incluiu 1) Preparação 2) Tradução para o português por três médicos, independentemente 3) Conciliação para versão única em português 4) Retradução 5) Comparação da retradução com a versão original 6) Avaliação pela autora do SNOT-22 da retradução 7) Revisão da versão em português por especialistas 8) Desdobramentos cognitivos 9) Versão final. A segunda fase: estudo prospectivo que verificou as propriedades psicométricas por meio da consistência interna e confiabilidade teste-reteste. Resultados: A adaptação cultural do instrumento apresentou compreensão e aceitabilidade adequadas. O coeficiente geral alfa de Cronbach foi igual a 0,88 e revelou boa consistência interna e o coeficiente de correlação intraclasse foi igual a 0,91, o que demonstrou excelente reprodutibilidade entre as medidas efetuadas. Conclusão: Conduzimos a adaptação cultural do SNOT-22 para o português falado no Brasil, produzindo um instrumento de grande importância clínica e para estudos científicos
Temperature acclimation before shipping and light acclimation after shipping improved the performance of Phalaenopsis after prolonged dark shipping
No full textMature, ready-to-bloom Phalaenopsis plants are often shipped by sea where they experience total darkness for a few weeks in cool air, in stark contrast to warm growing conditions in the greenhouse. After prolonged dark shipment, the plants experience a drastic change from total darkness to lighted conditions. The aim of this study was to investigate the effects of lower-temperature acclimation before shipping and light acclimation after dark storage on the quality and photosynthetic status of Phalaenopsis plants. Temperature acclimation at 25/20℃ day/niht temperatures for 10 d before shipment reduced the severity of chilling injury in mature Phalaenopsis plants in a cool and dark environment. The increased tolerance to chilling injury after temperature acclimation was not attributed to the changes of abscisic acid concentration in leaves. In another experiment, sudden exposure to a photosynthetic photon flus (PPF)of 399 μmol.m-2.s-1 after dark storage resulted in foliar chlorophyll degradation, restricted recovery of net CO2 uptake rate, and severely reduced maximal quantum efficiency of the leaves. Based on these three parameters investigated, an acclimation light intensity of 140 μmol.m-2.s-1 resulted in the best post-shipping performance of the plants. A gradual increase from low to moderate light levels is suggested as the ideal light acclimation protocol for cultivation of mature Phalaenopsis plants after prolonged dark storage
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
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
