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
(Effects of restricted and hypercaloric maternal diet on the metabolic and behavioral status of offspring : involvement of endocannabinoid system)
Full text linkTesis inédita de la Universidad Complutense de Madrid, Facultad de Psicología, Departamento de Psicobiología, leída el 11-09-2017La exposición a condiciones nutricionales adversas en periodos críticos del desarrollo, puede favorecer el desarrollo de alteraciones metabólicas o conductuales en etapas posteriores de la vida a través de un proceso denominado programación nutricional. Investigar los mecanismos biológicos que están envueltos en este fenómeno resulta una estrategia útil para entender la complejidad del fenómeno. El sistema endocannabinoide (SEC), implicado en el neurodesarrollo y en la regulación del metabolismo energético y de las respuestas emocionales, podría estar también involucrado en este proceso. Por tanto, en la presente investigación se planteó como objetivo estudiar los efectos de la dieta materna restringida e hipercalórica en: los resultados perinatales, los parámetros metabólicos y conductuales de la descendencia de ambos sexos, así como su impacto en el SEC de los descendientes en diferentes momentos del ciclo vital. Específicamente, 35 ratas Wistar hembra fueron asignadas a dieta control (C ), expuestas a dieta estándar durante el periodo perinatal (pregestación, gestación y lactancia); dieta restringida (R1), con una restricción calórica del 20% durante el periodo preconcepcional y hasta el día 20 de la gestación; y/o dieta hipercalórica/altamente palatable (P), expuestas a una libre elección entre una dieta estándar y una dieta rica en grasas saturadas hecha a base de chocolates comerciales durante todo el periodo perinatal. Adicionalmente, 11 ratas hembras Wistar fueron expuestas durante la gestación completa a dieta estándar o a restricción calórica del 20% (R2). Se monitorizó la ganancia ponderal e ingesta calórica de las madres durante el periodo de estudio...The exposure to adverse nutritional conditions in critical periods of development can increase the vulnerability to develop metabolic and behavioral alterations later in life, through a process known as nutritional programming. Investigating the underlying mechanism involved in this phenomenon has been considered a useful strategy to understand its complexity. The endocannabinoid system (ECS), which plays an important role on neurodevelopment and on the regulation of energy balance and emotional responses, might be involved in the programming process. Therefore, we aimed to study the impact of a restricted or hypercaloric maternal diet on the perinatal outcomes, metabolic and behavioral parameters of the offspring of both sexes, as well as their impact on the ECS at different stages of development. Accordingly, 35 female Wistar rats were assigned to a control diet (C), where rats were exposed to standard chow during the preconceptional, gestational and lactation periods; preconceptional and gestational restricted diet (R1), where rats were exposed to a 20% calorie-restricted diet during the preconceptional period up until gestational day 20; or a hypercaloric/highly palatable diet, in which rats were given a free choice between standard chow and a high fat containing commercial chocolate mixture diet during pregestation, gestation and lactation. An additional experiment was carried out in 11 female Wistar rats exposed during the entire pregnancy either to standard chow or a 20% calorie-restricted diet (R2). Weight gain and caloric intake of dams were monitored during the studied period...Depto. de Psicobiología y Metodología en Ciencias del ComportamientoFac. de PsicologíaTRUEunpu
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.
