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
The Effects of Wearable Resistance on Shoulder Strength and Throwing Velocity in Baseball Pitchers
No full textThrowing velocity is a key attribute for baseball pitchers. Accordingly, substantial effort has been dedicated to enhancing throwing velocity and its underlying characteristics. Wearable resistance (WR) for throwing athletes is a relatively new training method where micro-loads are attached to the throwing arm, allowing for load placement variation and deceleration phase overload, with the primary aim of sport specific strengthening of the throwing arm musculature. However, currently there is no research investigating WR utilisation to improve pitching performance. The overarching question of this thesis was what are the effects of throwing arm WR loading and training on shoulder strength and throwing velocity in pitchers?
This thesis encompassed a series of acute studies and a training study to address the research question. Two studies quantified peak force (Fmax) and rate of force development (RFD) reliability during shoulder internal (IR) and external rotation (ER) with strain gauge technology. First, swimmers (n = 18) were evaluated in three testing positions, with acceptable Fmax reliability observed in all positions (coefficient of variation, CV = 5.2-8.8%, intraclass correlation coefficient 95% confidence intervals, ICC 95% CI = .69-.98), however, RFD reliability was questionable (CV = 11.5-18.1%, ICC 95% CI = .34-.96). Subsequently, college and high school (HS) pitchers (n=15) were assessed in the supine 90o position, which provided the least variability. IR Fmax reliability was found acceptable (CV = 5.8%, ICC 95% CI = .56-.95), ER Fmax reliability was mixed (CV = 4.3%, ICC 95% CI = .39-.93) and RFD reliability unacceptable (CV = 16-29%, ICC 95% CI = .41-.97).
Relationships between shoulder rotator strength (Fmax and RFD during shoulder IR and ER) and throwing velocity was then explored. College and HS pitchers (n = 26) were assessed, the highest shared variance (adjusted R2 = .12-.13, p < .05) was between Fmax and throwing velocity. An acute WR throwing analysis with college and HS pitchers (n = 10) was used to quantify the effects of above and below elbow placement of WR (100-g, 150-g and 200-g) on throwing velocity, arm speed and temporal phase mechanics compared to unloaded trials. The effect of load on throwing velocity differed by placement with small to moderate reductions in throwing velocity (-1.8 to -2.7%, p < .01) detected with below elbow loads. Large decreases in arm speed (-5.1 to -6.5%, p < .05) with 150-g and 200-g below elbow were observed and the effects on temporal phase timing not clearly affected.
College pitchers (n = 17) were randomly assigned to a control or upper-arm WR group using a matched-volume design, implemented two times per week over six weeks of training. Pre- and post-test training of shoulder rotator strength, range of motion (ROM) and throwing performance unveiled no clear changes (p > .05) in throwing performance or shoulder rotator strength in either group. ER ROM increased over time (p < .05), predominantly attributed to changes in the control group (+15.8%). There is not sufficient evidence to support the use of WR for improving shoulder strength or throwing velocity in pitchers, within the protocols employed in this research. Despite unclear results, practical findings regarding shoulder strength assessment and suggestions for training pitchers were included in an opinion piece, which provides direction for practitioners and future researchers

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.
