Full Body Kinematics and Ground Reaction Forces of Fifty Heterogeneous Runners Completing Treadmill Running at Various Speeds and Gradients
Full text linkThis dataset includes 3-dimensional ground reaction force data (1000 Hz) collected from a gradient adjustable split belt Bertec instrumented treadmill (ITC-21-20) during running at a range of speeds and gradients. Alongside the ground reaction forces are marker based motion capture data. A full body markerset was tracked (250 Hz) using 12 Qualisys Miqus cameras and Qualisys Track Manager 2022, with additional anatomical markers tracked only during the static trial. Data was also collected from six inertial measurement unit sensors (Delsys Trigno) at 519 Hz, the sensors were secured to the following locations using either tape or Velcro strapping: medial left tibia, lateral left thigh, sacrum, T10 vertebrae, lateral left upperarm, and left wrist. All of this data was collected synchronously and saved to the typical motion capture format of c3d files. Fifty runners with mixed levels of experience and fitness levels are included in this dataset (25 males, 25 females).Full body kinematics were collected using a 12 camera Qualisys Miqus system (250 Hz), recordings for each trial were automated using a PAF project within Qualisys Track Manager 2022 software. Retroreflective marker locations are detailed within the 'MarkerSet_Info' document included in this dataset. All markers were secured with double sided tape and the clusters were also secured with medical bandages. Additional markers were used within a static trial, for the purpose of model scaling, prior to the start of the dynamic trials. Synchronised with the start of the motion capture recordings was the collection of three-dimensional ground reaction force data (1000 Hz) and inertial measurement unit data (519 Hz). The ground reaction force data was collected from a Bertec instrumented split belt treadmill (ITC-21-20), during the walking trials participants were instructed to walk across the two parallel belts with their left foot landing on force plate 1 and their right foot landing on force plate 2. During the running trials participants ran only on force plate 1 (left). The inertial measurement unit sensors used were the Delsys Trigno, collecting data through the Qualisys Track Manager API. The location of the sensors were based on common sensor locations within commercial wearable products. This included: medial left tibia, lateral left thigh, sacrum, T10 vertebrae, lateral left upperarm, and left wrist. The sensors were secured with a combination of double sided tape, adhesive spray, and velcro strapping depending on the location.
Participants were recruited from local running clubs and via word of mouth. The aim during recruitment was to make the sample as heterogeneous as possible, with a wide range of ages and abilities included. The final sample also included 25 biological males and 25 biological females. Before the start of data collection participants were asked for the typical pace that they would complete a 30+ minute easy run at. This then set the baseline for the other speeds that data was collected at during their participation. Full information about the speeds and gradients of each trial can be calculated through the information provided in the 'FileNaming_Convention' file and the data in the 'Participant_Info' file. The protocol consisted of walking as well as running during 'flat', uphill, and downhill conditions. Participants were provided breaks between trials and offered to opportunity to take as many breaks between trials as required, the aim was to minimise the influence of fatigue on individuals technique, whilst collecting a variety of running conditions.The only processing completed on this dataset was the labeling of marker trajectories within Qualisys Track Manager 2022. This labeling was completed to the best of our ability. However, due to obscured markers, poor marker tracking, or markers falling off the participant, every trial could not be perfectly labeled for the full length of the recording. It must also be noted that for some participants certain inertial measurement unit sensors fell off of the participant in later trials. As well as this, dropped samples within the delsys trigno sensors are seen, with certain participants' data heavily influenced by this. It is therefore advised if aiming to use the inertial measurement unit data within this dataset it is completed with caution and thorough gap filling and data screening is completed
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
