The Prevalence and Factors Associated with Knee Pain in a sample of Cyclists within the United Kingdom: A Cross Sectional Study
Purpose: The study aimed to determine: (i) the lifetime and period prevalence of knee pain, (ii) the prevalence and nature of medical attention cycling-related injuries, (iii) and the risk factors associated with knee pain and in a sample of competitive and non-competitive cyclists in the UK. Methods: A cross-sectional questionnaire was used to collect data on knee pain, medical attention injuries, and potential risk factors associated with knee pain. Participants were competitive and non-competitive cyclists aged 18 years and older and were recruited through cycling clubs and online advertisement. Binary logistic regression was used to assess for potential risk factors associated with knee pain. Crude and adjusted odds ratios were reported in staged adjustment models, controlling for potential confounders of age and sex. Keele University Ethics Committee approved this study. Results: A total of 115 respondents completed the questionnaire. Lifetime knee pain prevalence was 48%, with period prevalence 26.1% (past-month) and 18.3% (past-week). Aged 40 and over was the only factor found to be associated with knee pain, although this was no longer significant after adjustment for female sex. The most prevalent site and type of injury was the lower back and fracture (traumatic), respectively. Conclusion: Knee pain prevalence is high in this sample of cyclists, particularly in those aged 40 years and over. Injury prevention strategies should target the lower back and fractures. Longitudinal research is needed to identify if there are modifiable risk factors that may reduce the occurrence of both knee pain and traumatic fractures in cyclists
Board wargames for decision making research
This paper discusses some aspects of a game for research into decision making. From our experience with commercial board wargames, we identify six requirements for a research game, and three requirements for its control. The Organisational Control Game, a wargame which we have developed, is shown to satisfy the requirements. The Superior Commander system is used to control the game, and the importance of the dummy task is discussed. We conclude that commercial board wargames can be adapted to examine decision making scientifically, we offer some guidelines for game development, and we consider extensions to other contexts, particularly those related to business games
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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
