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
Efeito da prática de pilates sobre o equilíbrio de atiradores
Get PDFOrientador : Prof. Dr. André Luiz Félix RodackiDissertação (mestrado) - Universidade Federal do Paraná, Setor de Ciências Biológicas, Programa de Pós-Graduação em Educação Física. Defesa: Curitiba, 26/03/2015Inclui referênciasÁrea de concentração: Exercício e esporteResumo: A manutenção do equilíbrio é fundamental para realização de práticas esportivas, em especial para esportes de precisão como o tiro, onde o equilíbrio é essencial para garantir um bom desempenho. Um dos meios para melhorar a estabilidade corporal é por meio da ativação do core. Composto pelos músculos posturais do tronco e pelve, o core auxilia a manutenção do equilíbrio por meio da dissociação da musculatura profunda (responsável pela estabilização da coluna), enquanto a musculatura global realização os movimentos. Um dos métodos utilizados para trabalhar o core é o Pilates. Por meio de seis princípios (Centralização, Concentração, Controle, Precisão, Respiração e Fluidez) o Pilates melhora o equilíbrio estático e dinâmico, flexibilidade e a propriocepção. Com isso foram desenvolvidos dois objetivos para este estudo: 1. verificar a contribuição da estabilização central e do equilíbrio sobre o desempenho do atirador; 2. verificar os efeitos da prática do Pilates sobre o equilíbrio e estabilização central. Para isso, 32 cadetes da academia da Policia Militar foram alocados em grupo controle (GC, n=17, 25.65 ±4.4 anos) e grupo experimental (GE, n=15, 25.33±3.10). O desempenho do tiro foi avaliado com um sistema óptico a laser (SCATT). Enquanto o equilíbrio estático foi avaliado por meio da plataforma de força (PF) nas condições: durante o disparo e em posição tandem sobre a espuma. O equilíbrio dinâmico também foi avaliado pela PF a partir do teste de tiro de reação. Enquanto a estabilização central foi aferida pelo teste de abaixamento das pernas. Para verificar a influência sobre o desempenho do tiro, foi realizada uma regressão múltipla por etapa (p?0.05) e para verificar o efeito do Pilates foi utilizado o teste Kruskal Wallis, com post Hoc utilizando o teste Mann-Whitney com valor de p corrigido por Bonferroni (p?0.01). Para ambas as análises, foram utilizados dados de 5s e 1s antes do disparo. Os resultados da regressão múltipla mostraram que quanto maior a oscilação corporal na direção ântero-posterior (DAP) pior o escore do atirador (para 1s R²=0.232). Além disso, os resultados da comparação mostraram que o Pilates melhora a estabilização central (p=000), porém não foi suficiente para melhorar o equilíbrio ou o desempenho do atirador. A partir disso, conclui-se que um bom equilíbrio auxilia o sucesso no tiro, e que a prática de Pilates é eficaz para melhorar a estabilização central, porém não teve efeito sobre o desempenho do atirador. Palavras-chave: controle postural, equilíbrio, tiro, Pilates, core.Abstract: Maintaining balance is critical to performing sports activities, especially for precision sports such as shooting, where a good stability is essential to ensure good performance. One way to improve body stability is through core activation. Composed of the postural muscles of the trunk and pelvis, core helps maintain the balance by decoupling the deep muscles (responsible for the stabilization of the spine) meanwhile the global muscles perform the movements. One method to activate the core is Pilates. Through six principles (centering, concentration, control, precision, breath and fluidity) Pilates improves static and dynamic balance, flexibility and proprioception. Thus two objectives were developed for this study: 1. determine the association between core stability, balance and the shooter's performance; 2. verify the effects of Pilates practice on balance and core stability. For this, 32 cadets of the Academy of Military Police were divided into control group (CG, n = 17, 25.65 ± 4.4 years) and experimental group (EG, n = 15, 25.33 ± 3.10). The shooting performance was evaluated using an optical laser system (SCATT). Static balance was evaluated by force platform (FP) under the conditions: during shooting and tandem position on foam. Dynamic balance was also evaluated by FP during reaction shooting. The central stabilization was measured by double lowering legs (DLL). To check the influence on the shooting performance, a multiple regression stepway was performed (p?0.05) and to verify the effect of Pilates, the Kruskal Wallis test was used with post hoc by Mann-Whitney test with p value corrected by Bonferroni (p?0.01). For both analyzes, we used data from 5s and 1s before shooting. The results of multiple regression showed that the higher body sway toward posterior anterior (DAP) worse the shooter's score (for 1s R² = 0.232). Meanwhile, the comparison results showed that Pilates improves core stability (p = 000) but it was not able to improve balance or shooting performance. Thus, it follows that a good balance helps success in shooting, and that Pilates practice is effective to improve central stabilization, but had no effect on the shooter's performance.

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.
