The Influence of Footwear on Running Style and Injuries
Full text linkIn recent years running has become a very popular sport. Therefore it is nowadays often discussed whether it is shod running or barefoot running that is better. The aim of this thesis is to provide a summary of scientific pieces of knowledge on the effect of footwear on running style and related injuries. The introduction chapter describes the basics of running techniques and progressive development of running styles in relation to the development of running footwear. The following chapters describe in detail results of studies about the impact of footwear on kinematics, foot strike pattern and ground reaction forces, muscular activity and the running economy. Other chapters deal with the influence of footwear as a source of running related injuries while the most common running injuries are subsequently analysed. The last part is a practical section. It is a questionnaire study in which in total 93 runners participated. The conclusion summarizes the essential pieces of knowledge on the topic of footwear influence on running style and related injuries which are compared with the results collected in the questionnaire

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
Current concepts of double poling by classic technique in cross-country skiing.
Full text linkTitle of the thesis: Current concepts of double poling by classic technique in cross-country skiing Object of the thesis: The spatial-temporal analysis of node points and kinetic phases of the kick double poling and double poling of selected competitors at the FIS Nordic World Ski Championships in Liberec 2009. Method: A case study in which we used the kinematographic method for the analysis of the kick double poling and double poling of selected competitors. We analyzed the video of the 15-km classic in the FIS Nordic World Ski Championships in Liberec 2009. For the analysis we used the software APAS. Results: We performed spatial-temporal description of node points and kinetic phases of the kick double poling and double poling of selected competitors. We characterized current concepts of kick double poling technique, because selected competitors were relatively homogeneous set. By double poling we found out flexion-extension pattern in elbow, hip joints of slipping lower limb and partly in knee and ankle joints of slipping lower limb which results in generation of great propulsive force. Double poling becomes more significant driving element than push-off. Keywords: cross-country skiing, kick double poling, double poling, kinematic analysis, top competitor
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
