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
Construction risks in buildings in the El Lago area of Bogotá
No full textLa ingeniería civil tiene que desarrollar metodologías interpretativas que permitan mitigar los riesgos geotécnicos. Los riesgos geotécnicos aparecen cuando, por omisión, se desarrollan obras y estructuras que se apoyan sobre suelos cuyas particularidades de su formación necesitan de estudios adicionales y su respectiva evaluación, ya que podrían inducir inestabilidad en las construcciones.
Teniendo en cuenta que los suelos lacustres, caracterizados por su alta compresibilidad, elevado contenido de humedad y predominancia de arcillas blandas, representan uno de los mayores desafíos para la ingeniería civil debido a su susceptibilidad a fenómenos como asentamientos diferenciales, subsidencia y consolidación de suelos. Estos problemas comprometen la estabilidad de edificaciones e infraestructuras en ciudades construidas sobre antiguos sistemas lacustres, como Bogotá y la Ciudad de México, donde existen casos conocidos y emblemáticos (edificios en barrio El Polo y barrio El Lago en Bogotá; Catedral Metropolitana y Ángel de la Independencia en México) evidencian grietas, inclinaciones y hundimientos progresivos. Aunque existen normativas (NSR-10) y técnicas de mitigación (pilotes de fricción, subexcavación controlada), persisten las fallas en estudios geotécnicos exhaustivos, monitoreo del nivel freático y planificación urbana sostenible.
Este trabajo analiza las causas y soluciones de estos fenómenos mediante una metodología descriptiva-analítica, revisión bibliográfica y estudio de casos comparativos. Se identifican las características geotécnicas de los suelos lacustres y se proponen medidas correctivas con la actualización de mapas geotécnicos. La investigación menciona la necesidad de proteger humedales, regular extracciones de agua subterránea e implementar diseños estructurales adaptativos, contribuyendo a la gestión del riesgo geotécnico en contextos urbanos vulnerables.Civil engineering must develop interpretative methodologies to mitigate geotechnical risks. Geotechnical risks arise when, by omission, structures are built on soils whose formation characteristics require additional studies and proper evaluation, as they could lead to instability in constructions.
Considering that lacustrine soils, characterized by their high compressibility, elevated moisture content, and predominance of soft clays, represent one of the greatest challenges for civil engineering due to their susceptibility to phenomena such as differential settlements, subsidence, and soil consolidation. These issues compromise the stability of buildings and infrastructure in cities built on ancient lacustrine systems, such as Bogotá and Mexico City, where well-known and emblematic cases (buildings in the El Polo and El Lago neighborhoods in Bogotá; the Metropolitan Cathedral and the Angel of Independence in Mexico) exhibit cracks, tilting, and progressive sinking. Although regulations (NSR-10) and mitigation techniques (friction piles, controlled under-excavation) exist, failures persist in thorough geotechnical studies, groundwater level monitoring, and sustainable urban planning.
This work analyzes the causes and solutions to these phenomena using a descriptive-analytical methodology, literature review, and comparative case studies. The geotechnical characteristics of lacustrine soils are identified, and corrective measures are proposed, including the updating of geotechnical maps. The research highlights the need to protect wetlands, regulate groundwater extraction, and implement adaptive structural designs, contributing to geotechnical risk management in vulnerable urban contexts.CONTENIDO

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.
