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
Análisis de tres casos representativos de vulnerabilidad de obras de infraestructura ante movimientos de masa de origen climático y/o cosísmicos en el Estado Táchira (Venezuela)
No full textLos Andes del Táchira constituyen una de las regiones de Venezuela con mayor potencial de riesgo de origen geológico y sísmico, razón por la cual los movimientos de masa disparados periódicamente en época de lluvias o por eventos sísmicos, inclusive de media a baja magnitud, se convierten en un factor a priori significativo de vulnerabilidad y falla de las obras de infraestructura, con el correspondiente saldo de víctimas y pérdidas materiales. El presente trabajo reúne tres estudios de casos concernientes al estado Táchira, donde obras de ingeniería han colapsado o sufrieron severas deformaciones permanentes por encontrarse construidas en sitios geológicamente inestables. En los tres casos, es notorio que el comportamiento conflictivo de la obras no obedece a causas naturales, sino al desconocimiento o menosprecio de las condiciones de sitio locales, previamente a la construcción de aquellas obras. En dos de estos casos, el agente disparador es un evento sísmico de moderada a baja magnitud, que coincide con la época de lluvia. En el tercer caso, es el propio acondicionamiento geotécnico del sitio de ubicación de la obra el responsable de la falla de la misma, al haberse amputado el frente de un deslizamiento rotacional para dar paso a una autopista y resultar severamente deformada la vía, debido a la aceleración de los empujes de tierra en un período de intensas precipitaciones. La ubicación imprudente de obras de importancia vital en condiciones de sitio geológicamente inestables, contribuye en forma significativa a la vulnerabilidad funcional de las mismas y al acortamiento de su vida útil, no obstante los gastos de reparaciones y mantenimiento pueden superar con creces el costo inicial de aquellas obras. Analysis of three representative cases of infrastructure vulnerability to mass movements of climatic and/or co-seismic origin, in Táchira State (Venezuela)AbstractThe táchira Andes constitute one of the regions of Venezuela with major geologic and seismic risk. For this reason, mass movements periodically triggered during the rainy season or by seismic events of small to medium magnitude may become a significant a priori vulnerability factor of infrastructure leading to human victims and material loss. In this work, three cases were analyzed in táchira state, where engineering projects have collapsed or have been deformed because they were constructed in geologically unstable zones. In the three cases, it is worth noting that the conflictive behavior of the structures does not obey to natural causes. Instead, it reflects the lack of knowledge or disregard for the potentially unstable places before the design and construction of the infrastructures analyzed. In two of the cases, the trigger was a seismic event of small to moderate magnitude which coincided with the rainy season. In the third case, it is the very geotechnical condition of the structure’s location site that is responsible for its failure, since the front of a rotational landslide was cut off to make way for a highway. This resulted in severely deforming the road due to the acceleration of earth sliding during a period of heavy rains. The inappropriate location of infrastructure of vital importance in geologically unstable places significantly contributes to their vulnerability and a shortening of their useful life time, not withstanding, the costs of repair and maintenance that may grow beyond the initial cost of these projects
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.
