Upper respiratory tract symptoms and allergies in Ironman triathletes
No full textIncludes bibliographical references (leaves 69-77).Triathletes, in particular Ironman triathletes, undergo intense training and compete in a very physically demanding race. Medical conditions in the pre-race period in these triathletes have not been well documented, but there is evidence form other endurance sports that symptoms of respiratory tract infection are particularly common. However, the prevalence, causes and consequences of these symptoms have not been studied in Ironman triathletes. The aims of this study were: 1) to determine the incidence of respiratory tract symptoms (RTS) in triathletes preparing for an Ironman Triathlon, 2) to establish the factors associated with the development of these RTS, and 3) to determine the effects of the RTS on pre-race training and race performance. Methods: In this cross-sectional descriptive study, 304 triathletes entering the 2006 Ironman triathlon in South Africa were recruited as subjects. All the subjects completed a validated questionnaire in the 1-3 days before the race (during registration). The questionnaire contained sections on demographics, training and previous competitions, common general medical conditions that they may have experienced, and a detailed section pertaining to RTS and allergies, including use of medication. Data on race performance was collected after completion of the race. Subjects were divided into the following groups, based on their self-reported history of RTS in the 6 weeks period prior to the race: no RTS, all RTS, only upper respiratory tract symptoms (URTS), lower respiratory tract and/or systemic symptoms (LRT +SS)
The great pretender: Multi-system tuberculosis and pathological fracture masquerading as a severe acute football groin injury ‒ Case study with a 5-year follow-up
Get PDFIn this clinical case, a man presented with a groin injury on his dominant side, which he apparently sustained in football (soccer) practice on the previous day. The man was unable to walk unassisted and had to be transported in a wheelchair. The consulting practitioner grew suspicious upon finding minimal clinical evidence and nothing notable on the X-ray to suggest a severe acute injury. A subsequent detailed workup revealed extrapulmonary tuberculosis (EPTB) of the musculoskeletal (MSK) and genitourinary tract (GUT) systems, complicated by a pathological fracture of the acetabulum, as the cause of the groin injury. Management of the EPTB resolved the condition with no relapse nor long-term sequelae beyond five years, despite being immunocompromised. We present the clinical case and a five year follow-up. The case serves as a reminder of the possibility that other conditions may mimic sports injuries and further illustrates a rare presentation of such a condition
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
