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
Análisis de los sistemas de seguimiento de jugadores basados en GNSS y posicionamiento local para su aplicación al fútbol
Get PDFLa presente tesis doctoral tuvo los siguientes objetivos generales (OG) y específicos (OE): (i) OG: diseñar un montaje válido y fiable para la sincronización automática de un sistema inercial y unas puertas de tiempo; (ii) OE: analizar la precisión del protocolo de comunicación creado entre el sistema inercial y el sistema de referencia (puertas de tiempo); (iii) OE: determinar la validez del montaje en el sistema inercial para medir sprint y el tiempo empleado en realizar pruebas deportivas; por otro lado, (iv) OG: determinar la precisión y fiabilidad entre unidades y test-retest de los sistemas de seguimiento por radiofrecuencia (GPS y UWB); (v) OE: comparar los dos sistemas de seguimiento para su aplicación al análisis de tiempo-movimiento en futbol; y por último, (vi) OG: examinar la precisión y fiabilidad de los sistemas de seguimiento por radiofrecuencia (GPS y UWB) para la determinación de la posición de jugadores en el campo en fútbol; (vii) OE: comparar la precisión y fiabilidad de ambos sistemas de seguimiento (GPS y UWB) para la estimación de la posición de jugadores en el campo; y (viii) OE: comparar los dos sistemas de seguimiento para su aplicación al análisis táctico. Para todo ello, se diseñaron distintos protocolos experimentales en función del objetivo perseguido. Para los objetivos 1-3 se diseñó y ejecutó una modificación en la comunicación de ambos sistemas (IMU y puertas de tiempo) para que la sincronización entre ambos fuera automática. Para los objetivos 4 y 5 se diseñó un circuito con movimientos típicos del rendimiento en futbol y se midieron la distancia recorrida y la velocidad mediante GPS y UWB para comparar sus datos con las medidas reales (cinta métrica y puertas de tiempo respectivamente). Para los objetivos 6-8 se diseño un circuito que incluyera movimientos típicos del futbol y además fuera geométrico a fin de poder ser comparados con polígonos creados digitalmente. En conclusión, las medidas de tiempo por el montaje entre un sistema inercial y unas fotocélulas comunicadas mediante tecnología ANT + obtuvieron una alta precisión, por lo que se podría aplicar para hacer más eficiente la monitorización del tiempo en la actividad deportiva. Además, se consigue una sincronización automática entre las medidas de tiempo y las medidas integradas en el sistema inercial. Por otro lado, se mostró que tanto GPS como UWB fueron sistemas adecuados para medidas de tiempo-movimiento en el futbol, aunque se observó que UWB obtuvo mayor precisión que GPS en condiciones estáticas y en largos periodos de tiempo. Ambos sistemas además fueron altamente fiables. Finalmente, para su aplicación al análisis táctico y para la estimación de la posición exacta de jugadores se reportó una alta precisión y fiabilidad del sistema UWB, en contraste con el sistema GPS.The present doctoral thesis had the following general (OG) and specific (OE) objectives: (i) OG: to design a valid and reliable assembly for the automatic synchronization of an inertial system and photocells; (ii) OE: analyze the accuracy of the communication protocol created between the inertial system and the reference system (photocells); (iii) OE: determine the validity of the assembly in the inertial system to measure sprint and the time spent in performing sports tests; on the other hand, (iv) OG: determine the accuracy and reliability between units and test-retest of radiofrequency tracking systems (GPS and UWB); (v) OE: compare the two tracking systems for their application to the analysis of time-motion patterns in soccer; and finally, (vi) OG: to examine the accuracy and reliability of radiofrequency tracking systems (GPS and UWB) for the determination of the position of players in the field in soccer; (vii) OE: compare the accuracy and reliability of both tracking systems (GPS and UWB) for estimating the position of players in the field; and (viii) SO: compare the two tracking systems for their application to tactical analysis. For all this, different experimental protocols were designed according to the objective pursued. For objectives 1-3 a modification was designed and executed in the communication of both systems (IMU and photocells) so that the synchronization between both was automatic. For objectives 4 and 5 a circuit was designed with typical movements of soccer performance and the distance traveled and speed were measured by GPS and UWB to compare their data with the real measurements (tape measure and time gates respectively). For objectives 6-8, a circuit was designed that included typical soccer movements and was also geometric in order to be compared with digitally created polygons. In conclusion, the time measurements for the assembly between an inertial system and some photocells communicated by ANT + technology obtained a high precision, so it could be applied to make more efficient the monitoring of the time in the sport activity. In addition, an automatic synchronization between the time measurements and the integrated measures in the inertial system is achieved. On the other hand, it was shown that both GPS and UWB were suitable systems for time-movement measurements in soccer, although it was observed that UWB obtained greater accuracy than GPS in static conditions and over long periods of time. Both systems were also highly reliable. Finally, for its application to the tactical analysis and for the estimation of the exact position of players, a high accuracy and reliability of the UWB system was reported, in contrast to the GPS system
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.
