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

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.

Descripción y análisis de las cargas de competición en jóvenes tenistas y estrategias para optimizar su rendimiento
Full text linkEl afán por la búsqueda de la excelencia deportiva y la llegada al profesionalismo está provocando en el tenis una cada vez más temprana especialización deportiva. Para ello, los jóvenes tenistas deben enfrentarse, a largo de una temporada, a calendarios enormemente exigentes sin un control adecuado de las cargas de trabajo. Estas situaciones implican la disminución del rendimiento, teniendo que recurrir a la búsqueda de estrategias que ayuden a mitigar estos efectos.
En la presente Tesis Doctoral se presentan cuatro estudios científicos de carácter multidisciplinar. Uno de ellos basado en jugadores y jugadoras profesionales. Los otros tres, todos ellos estudios ecológicos, llevados a cabo con tenistas jóvenes de competición. El primer estudio analizó el patrón evolutivo de la edad de los 100 mejores tenistas profesionales del circuito masculino y femenino en las últimas décadas. Se observó un incremento progresivo de la edad promedio en ambos circuitos, así como el retraso en el acceso y en el pico de rendimiento de los jugadores incluidos en estas posiciones de privilegio. El segundo estudio comparó los patrones de actividad y desplazamiento realizado por tenistas jóvenes a lo largo de una competición simulada con dos partidos en un mismo día. Ambos patrones fueron diferentes en los dos partidos (i.e., mayor duración, mayor distancia total recorrida, más acciones de aceleración y deceleración, mayores tiempos de descanso entre puntos y mayor esfuerzo percibido por los jugadores en el partido de la sesión de tarde frente al de la mañana). Se observaron escasas diferencias entre los ganadores y perdedores de los partidos (i.e., mayor velocidad máxima obtenida por aquellos que perdieron los partidos). El tercer estudio analizó el efecto provocado por un día de competición con dos partidos sobre el rendimiento de jugadores jóvenes, concluyendo que dicha carga competitiva provocó déficits neuromusculares en tren superior (i.e., disminución de la producción de fuerza y variación de rangos de movimiento de hombro) e inferior (i.e., disminución de la altura de salto, de la velocidad de sprint y de la velocidad de cambio de dirección). Por último, el cuarto estudio buscó determinar el posible efecto ergogénico que provoca una bebida energética con 3 mg de cafeína por kg de peso corporal sobre el rendimiento en tenistas jóvenes, evidenciando la mejora de variables implicadas en el rendimiento neuromuscular (i.e., incremento de la fuerza de prensión manual, de la distancia recorrida a alta intensidad y del número de sprints) y técnico (i.e., mayor porcentaje de puntos ganados con el servicio).
A la luz de estos resultados, se podrían sugerir ciertas estrategias que podrían favorecer el desarrollo deportivo de los tenistas jóvenes, en aras de lograr un mejor rendimiento competitivo y carreras deportivas más saludables y longevas. En primer lugar, contemplar el inicio de la especialización deportiva teniendo en cuenta el pico de rendimiento del tenis profesional; en segundo lugar, monitorizar y adecuar las cargas de entrenamiento respecto a las cargas observadas en competiciones con más de un partido en el mismo día; en tercer lugar, inculcar el trabajo de recuperación y prevención neuromuscular inter y post-partido en ese tipo de competiciones, y llevarlas al entrenamiento; y por último, profundizar en el uso de la cafeína como posible estrategia nutricional de mejora del rendimiento en el tenis a través de la adaptación y el control de los posibles efectos secundarios
