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
Sq current system at the fuquene geomagnetic observatory and its relationship with the difi-7 model
No full textEsta monografía de pregrado con un enfoque en investigación científica se centra en el estudio de la variación solar en calma (Sq) del campo magnético ionosférico en el Observatorio Geomagnético de Fúquene (FUQ), así como su comparación con el modelo global DIFI-7. Inicialmente parte de una revisión teórica de las fuentes del campo geomagnético, tanto internas (núcleo y corteza terrestre), como externas (ionósfera y magnetósfera). Se describe los principales sistemas de corrientes ionosféricas, tales como el Electrochorro Ecuatorial (EEJ), el Electrochorro Auroral (AEJ) y el sistema Sq, analizando su generación, comportamiento y relevancia científica.
Posteriormente, se describe el funcionamiento, la historia y la instrumentación del Observatorio Geomagnético de Fúquene, incluyendo la metodología empleada para la digitalización de magnetogramas históricos y la obtención de los datos. Se calcula el residuo del campo ionosférico observado a partir de la sustracción de las contribuciones internas y externas modeladas por CHAOS-8 y se compara con las predicciones del modelo DIFI-7 para distintos periodos geomagnéticos: uno en calma entre el 2 y el 9 de octubre de 2014 y otro perturbado entre el 8 y el 15 mayo de 2024.
Los resultados obtenidos evidencian una buena correspondencia entre las señales modeladas y observadas bajo condiciones de baja actividad geomagnética, encontramos que las diferencias entre el residuo y el modelo alcanzan valores entre 0.14 y 33.4 nT en la componente radial, entre 0.13 y 26 nT en la componente polar y entre 0.05 y 25.56 nT en la componente azimutal. Mientras que durante condiciones de alta actividad geomagnética encontramos que las diferencias entre el residuo y el modelo alcanzan valores entre 0.3 y 91.85 nT en la componente radial, entre 0.18 y 224.18 nT en la componente polar y entre 0.06 y 87.97 nT en la componente azimutal, asociadas a la sensibilidad del modelo frente a grandes cambios generados por tormentas geomagnéticas. Este estudio demuestra la utilidad del modelo DIFI-7 para representar la corriente Sq en Colombia y valida la calidad de los datos obtenidos por el observatorio FUQ, lo cual abre nuevas posibilidades para el monitoreo y modelado del campo geomagnético en regiones ecuatoriales.This undergraduate thesis, with a focus on scientific research, centers on the study of solar quiet variation (Sq) of the ionospheric magnetic field at the Fúquene Geomagnetic Observatory (FUQ), as well as its comparison with the global model DIFI-7. It begins with a theoretical review of the sources of the geomagnetic field, both internal (core and Earth's crust) and external (ionosphere and magnetosphere). The main ionospheric current systems are described, such as the Equatorial Electrojet (EEJ), the Auroral Electrojet (AEJ), and the Sq system, analyzing their generation, behavior, and scientific relevance.
Subsequently, the operation, history, and instrumentation of the Fúquene Geomagnetic Observatory are described, including the methodology used for the digitization of historical magnetograms and data acquisition. The residual of the observed ionospheric field is calculated by subtracting the contributions of both internal and external components, modeled by CHAOS-8, and it is compared with the predictions from the DIFI-7 model for different geomagnetic periods: one quiet period between October 2 and 9, 2014, and one disturbed period between May 8 and 15, 2024.
The results show a good correspondence between the modeled and observed signals under conditions of low geomagnetic activity. We found that the differences between the residual and the model range from 0.14 to 33.4 nT in the radial component, from 0.13 to 26 nT in the polar component, and from 0.05 to 25.56 nT in the azimuthal component. Meanwhile, under conditions of high geomagnetic activity, the differences between the residual and the model range from 0.3 to 91.85 nT in the radial component, from 0.18 to 224.18 nT in the polar component, and from 0.06 to 87.97 nT in the azimuthal component, which are associated with the model's sensitivity to large changes caused by geomagnetic storms. This study demonstrates the usefulness of the DIFI-7 model for representing the Sq current in Colombia and validates the quality of the data obtained by the FUQ observatory, thus opening new possibilities for the monitoring and modeling of the geomagnetic field in equatorial regions

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.
