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
Simulação de fenômenos termo-fluidodinâmicos pelo emprego dos métodos de diferenças finitas à solução da equação de Boltzmann

"Kinetic theory representation of hydrodynamics: a way beyond the Navier-Stokes equation". Journal of Fluid Mechanics, v. 550, p.413-441) e Philippi e colaboradores (PHILIPPI, P. C. et al. "From the continuous to the lattice Boltzmann equation: The discretization problem and thermal models". Physical Review E, v. 73, n. 5, p. 056702), em 2006, reabriram a perspectiva de uso do lattice Boltzmann para a simulação de escoamentos não isotérmicos e/ou a alto número de Knudsen através da resolução direta da equação de Boltzmann ao estabelecerem uma ligação sistemática e consistente entre a Teoria Cinética dos Gases e os métodos de lattice Boltzmann (LBM), determinando condições necessárias para a discretização do espaço de velocidades em diferentes ordens do número de Knudsen. As redes obtidas através do método proposto por eles, de abscissas prescritas, provaram ser estáveis em escoamentos em uma ampla faixa de parâmetros. Levando em consideração que as redes obtidas através deste método aumentaram significativamente o número de velocidades moleculares necessárias para a discretização do espaço de velocidades e os fenômenos físicos descritos por esta formulação possuem grande complexidade, exigindo uma maior quantidade de parâmetros para que os coeficientes de transporte do fluido simulado em várias escalas de Knudsen possam ser corretamente ajustados, diversas adaptações aos LBMs convencionais precisaram ser realizadas. Modelos de colisão a múltiplos tempos de relaxação, adequados ao ajuste dos coeficientes de transporte do fluido simulado, foram propostos. Um modelo de colisão a dois tempos de relaxação será discutido e analisado nesta tese. Do ponto de vista numérico, métodos mais acurados em relação a sua discretização espacial e temporal foram testados com o objetivo de melhorar a representação numérica dos efeitos físicos relacionados a números de Knudsen finitos, de forma que o comportamento do modelo de colisão utilizado fosse representado com mais acurácia, evitando que ele se confundisse com erros numéricos do método de solução. Condições de contorno adequadas à simulação destes escoamentos também tiveram que ser propostas. Seu uso em simulações utilizando diferentes métodos numéricos revela a dificuldade em ajustá-las quando fenômenos em uma escala inferior a da fluidodinâmica são considerados. Todos os métodos propostos foram analisados através da expansão de Chapman-Enskog. O objetivo destas análises foi comparar os métodos numéricos e os modelos de colisão no contínuo teoricamente, prevendo as equações macroscópicas que eles deveriam obedecer em diversas ordens do número de Knudsen. Depois de uma extensa discussão teórica sobre o método de lattice Boltzmann, diversas simulações foram realizadas com o objetivo de testar: i) o efeito que a correta representação de ordens crescentes dos momentos da distribuição de equilíbrio do contínuo no espaço discreto de velocidades possui, ii) a acurácia dos diferentes métodos de diferenças finitas empregados em diversas ordens de Knudsen, iii) a acurácia das análises de Chapman-Enskog realizadas e por fim, iv) a influência das condições iniciais e de contorno na evolução de escoamentos simulados a diversas ordens do número de Knudsen
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

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.
