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
Randomised crossover trial of m. gluteus maximus and m. gluteus medius activation during rehabilitation exercises in female hockey players
No full textIntroduction: Various researchers have focused on the activation capabilities of the gluteal muscles during different commonly used rehabilitation exercises. However, there is currently a lack of research in examining body weight rehabilitation exercises that elicit the highest percentage maximal voluntary isometric contraction (%MVIC) for both the m. gluteus maximus (mGmax) and m. gluteus medius (mGmed) in a high-performance athletic population. Field hockey predominantly requires maintaining a forward flexed posture, which places excessive stress on the lumbar spine of the players. Hence, it is necessary to assess the muscles that support the lumbar spine, especially the muscles that surround the hip, in order to prescribe strengthening exercises for this population. Knowledge of the percentage activation of the mGmax and mGmed elicited during body weight rehabilitation exercises may result in more specific exercise programme prescription during prehabilitation and the later stages of rehabilitation for high-performance female field hockey players. Objectives: The aim of the study was first to establish which commonly prescribed body weight rehabilitation exercises from previous studies produced greater than 61%MVIC for both the mGmax and mGmed. Hereafter, the study examined the exercises that fall into this category to determine which exercise will elicit the highest %MVIC, defined as the peak normalised sEMG signal amplitude, in high-performance female field hockey players of the University of the Free State (UFS). Methods: Surface electromyography (sEMG) was used to record the muscle activation of the mGmax and mGmed of four (4) body weight rehabilitation exercises on twenty-six (26) highperformance female field hockey players of the UFS. The %MVIC activation data of both the mGmax and mGmed were analysed using a three-way ANOVA, with ‘participant’, ‘period’ and ‘exercise’ as categorical variables in the model. Point estimates for the mean %MVIC for each exercise were reported, as well as point estimates, 95% confidence intervals (CIs) and p-values for the pairwise differences in peak %MVIC between the four body weight rehabilitation exercises. For each variable analysed, the overall F-test for the four body weight rehabilitation exercises is reported, as well as the partial effect size measure for ANOVA. Results: The mean age of the participants was 20.15±1.59 years, the mean height was 164±0.07cm, mean body mass was 64.72±10.21kg, and mean BMI was 23.87±2.92kg.m². Side-plank hip abduction with dominant leg on bottom generated a 124.61±7.94%MVIC of the mGmax and a 126.07±14.16%MVIC of the mGmed. Side-plank hip abduction with dominant leg on top generated a 124.33±8.63%MVIC of the mGmax and a 124.52±11.37%MVIC of the mGmed. The single-leg squat generated a 125.65±10.13%MVIC of the mGmax and a 126.30±12.89%MVIC of the mGmed. Plank with hip extension generated a 122.73±9.37%MVIC of the mGmax and a 125.04±13.14%MVIC of the mGmed. Concerning the mGmax, there was no significant difference found in activation when sideplank hip abduction with dominant leg on bottom was compared to side-plank hip abduction with dominant leg on top (p=0.8475, d=0.28), the single-leg squat (p=0.4807, d=-1.03) and plank with hip extension (p=0.2000, d=1.88). Furthermore, no significant difference was found when side-plank hip abduction with dominant leg on top was compared to the singleleg squat (p=0.3685, d=-1.31) and plank with hip extension (p=0.2770, d=1.60). However, there was a significant difference between the single-leg squat and plank with hip extension (p=0.0487, d=2.91). Concerning the mGmed, there was no significant difference in activation when side-plank hip abduction with dominant leg on bottom was compared to the side-plank hip abduction with dominant leg on top (p=0.3272, d=1.54), the single-leg squat (p=0.8837, d=-0.23) and plank with hip extension (p=0.5134, d=1.03). Furthermore, no significant difference was found when side-plank hip abduction with dominant leg on top was compared to the single-leg squat (p=0.2606, d=-1.77) and plank with hip extension (p=0.7437, d=-0.52) or between the single-leg squat and plank with hip extension (p=0.4240, d=1.26). When the exercise effect is combined, the four body weight rehabilitation exercises did not significantly affect either mGmax (p=0.2558) or mGmed (p=0.6285) activation. Conclusion: The four body weight rehabilitation exercises examined by the study generated very similar %MVIC activation of the mGmax and mGmed in high-performance female field hockey players. This research enables practitioners to apply evidence-based practice into programme prescription. Implementation of the findings of the current study could result in significant benefits during prehabilitation, injury prevention programmes and the later stages of rehabilitation for high-performance female field hockey players. The conditioning coach stands to benefit, especially given that these exercises can be executed on the playing pitch as part of a warm-up without the need for any equipment

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.
