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

Transient discharge of a pressurised incompressible fluid through a pipe and analytical solution for unsteady turbulent pipe flow
Get PDF[Resumo] Estúdase a dinámica do proceso de descarga súbita dun líquido presurizado á atmosfera, de
amplo interese en Enxeñaría de protección contra incendios. Preséntase o estado da arte respecto
ao estudo do proceso de descarga. Elabórase un modelo hidráulico unidimensional para ese fluxo,
que adopta a forma dunhas ecuacións intregro-diferenciais ordinarias que resólvense numéricamente.
Efectúase unha análise de sensibilidade respecto a todos os parámetros dos que depende o modelo, con
especial fincapé na fricción xerada pola turbulencia.
Analizanse os métodos xenéricos de descrición da turbulencia, incluíndo a representación estatística, o
filtrado de magnitudes turbulentas e a plena descrición analítica. Desenvólvese unha solución analítica
xeral para o fluxo turbulento, incompresible e non estacionario nunha tubaxe.
Elabórase un modelo computacional tridimensional para o fluxo descrito. A modelización da turbulencia
resulta ser o punto mais importante e conflitivo de dito modelo. Compáranse os resultados obtidos
con eles preditos polo modelo hidráulico unidimensional desenvolto previamente. Preséntanse resultados
diso á estrutura interna da turbulencia en fluxos fortemente acelerados, prevéndose un aumento notable
da devandita turbulencia nas proximidades do muro, que non se explica unicamente polo número
de Reynolds.[Resumen] Se estudia la dinámica del proceso de descarga súbita de un líquido presurizado a la atmósfera,

atmosphere is studied, a case of broad interest in fire protection Engineering. The state of the art in
the literature regarding such discharge process is presented. A one-dimensional hydraulic model is
developed for this flow, which takes the form of ordinary intregro-di ferential equations that are solved
numerically. A sensitivity analysis is carried out with respect to all the parameters on which the model
depends, with special emphasis on the friction generated by the turbulence.
The generic methods of describing turbulence are analysed, including the statistical representation, the
filtering of turbulent quantities and the full analytical description. A general analytical solution for the
turbulent, incompressible and unsteady flow in a pipe is developed.
A three-dimensional computational model for the described flow is elaborated. The modelling of
turbulence turns out to be the most important and conflicting point of such model. The results obtained
are compared with those predicted by the one-dimensional hydraulic model previously developed.
Results are presented regarding the internal structure of the turbulence in strongly accelerated flows.
A remarkable increase of said turbulence is anticipated in the proximities of the wall, that could not be
explained only with the Reynolds number
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.
