    Mission success: mastering muscle function through humanoid analysis

    Get PDF
    Knowledge of muscle function and human movement are essential skills of all kinesiology students. In the humanoid activity, teams are challenged to determine whether a muscle is essential to the successful development of a humanoid being sent to Mars. This activity provides a significant learning experience regarding muscle anatomy, function, and movement analysis. The humanoid activity is intended for use in a face-to-face upper-level kinesiology anatomy or movement analysis course and best implemented with class sizes of 20-30 students. The total time commitment is approximately 45 minutes

    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

    THE DIFFERENCE IN LOADED V.S. UNLOADED VERTICLE JUMP

    The purpose of this study was to measure the difference in a loaded versus unloaded vertical jump on jump height and muscle activation. It was hypothesized that the loaded vertical jump would have a significant increase in comparison to the unloaded vertical jump due to the stimulus that the resistance band would apply. The muscle focused on in this study was the Gastrocnemius. The gastrocnemius is known to aid in knee flexion during the loading phase (phase one) and assist in plantar flexion at the talocrural joint in the jumping phase (phase two). 8 healthy young athletes (female = 3) were recruited for this study. The protocol for this study consisted of a five-exercise warm-up, then would perform a vertical jump for the first comparison. After five minutes of rest, the participant would then perform a loaded squat with a resistant band and immediately perform a vertical jump for the second comparison. The process was repeated such that each subject performed two trials of both the loaded and unloaded jumps. All jumps were performed on a Just Jump Mat ® which reported jump height in inches. Electromyography (EMG) was recorded in the gastrocnemius muscle with Delsys Trigno wireless sensors. The root mean square of the EMG signal was computed. A paired sample T-test was used to compare the average peak EMG signal and height of both vertical jumps. We determined from the p-value of the vertical jump (p=.103), and the p-value of the EMG (p=.474) that there was no significant difference between the two jumps because the value of each was greater than .05. In conclusion, for both the unloaded and loaded vertical jump there was no significant difference reported. This study would be best applied to athletic individuals who compete in some sort of power-type sport. The limitations we had in this study were the small number of participants gathered for the study (n=8), The height of the participant which would impact the total resistance of the band, the amount of resistance, and the lack of experience of the individuals performing the loaded squat. Reasoning for why this study didn’t work could be due to the limiting factor that the participant in the study had little to no experience in performing a squat with a loaded resistance such as the resistance band. Future studies should provide familiarization trials and normalize the length of the resistance band

    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

    Get PDF
    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

    No full text
    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
