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

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.

Programación de la producción de calzado de seguridad basado en la teoría de restricciones para la mejora de la productividad en la Empresa Marcia- Buffalo Industrial.
Get PDFSe realizó un estudio de los parámetros de producción en la empresa de calzado de seguridad MARCIA BUFALO INDUSTRIAL; como: inventario en proceso por sus siglas en inglés (WIP), tiempo de ciclo (CT) y tasa de producción de unidades vendibles throughput (TH), los parámetros se obtienen de la teoría de restricciones propuesta por Goldratt y luego se las evaluó con la Ley de Little que propone Hopp y Spearman, se aplicó el estudio realizado para programar la producción de calzado de seguridad que permitirá utilizar la capacidad máxima de la línea, elevando el TH, reduciendo el CT y manteniendo un WIP constante a través de la reducción de los desperdicios de tiempo generado en los procesos. Para evaluar el caso actual y el propuesto, se utilizó un software de simulación Promodel® versión estudiantil, con el cual se programó algoritmos de secuencia de operaciones, parámetros de producción para el mejor caso posible que permita elevar la productividad de la empresa. Como resultado se obtuvo las cantidades optimas de producción para un ciclo de trabajo de 8 horas, elevando el throughput de 0,50 pares / min a 0,53 pares/ min, reduciendo el CT de 478,83 min a 450,3 min, teniendo un aumento en la producción, de 10 pares de calzado de seguridad en una jornada, además se determinó, que el inventario en proceso optimo por cada hora de trabajo es de 32 pares. Finalmente se genera una secuencia de operaciones a través de un diagrama de Gantt para una programación óptima de producción, en el que para una orden de 520 pares del calzado en estudio se gana 66 minutos en el ciclo de trabajo al mantener un inventario en proceso constante. Este estudio puede aplicarse en empresas de calzado que presenten similares características del caso investigado.A study was about made about the parameters within the safety shoemaking factory MARCIA BUFALO INDUSTRIAL, such as: work in process for its acronym in English (WIP), CYCLE TIME (CT) and the throughput sold units of production rate (TH), the parameters were obtained based on the theory of restrictions proposed by Goldratt and then this was evaluated with the Little Law that proposes Hopp and Spearman, the made study was applied to program the safety shoe production that will allow to use the line maximum capacity, by increasing the TH, decreasing the CT and keeping a constant WIP by means of the reduction of the wasting time performed in the processes. To evaluate the current case and the proposed, a simulation program software Promodel® was used, in its student version, with which the sequence algorithms were programmed, production parameters for the best case that increases the productivity of the factory. Therefore, the optimal quantities of production for a work cycle of 8 horas were obtained, by increasing the throughput of 0,5 pairs/min, decreasing the CT of 487,83 min to 450,3 min, and having an increase in the production, of 10 safety shoes in a work cycle.
Furthermore, it was determined that the inventory in optimal process per each hour of work is of 32 pairs. Finally, a sequence of operations through a Gantt diagram for the optimal production programming was generated, in this for a petition of 520 shoe pairs in the study 66 min are gained in the work cycle to keep a constant work in process. This study could be applied in shoemaking factories that present the same characteristics of the investigated case
