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
Indicadores morfométricos del carcinoma papilar de tiroides diagnosticado por biopsia escisional
Get PDFBackground: thyroid is where malignant endocrine tumor diseases originate more frequently. This entity possesses multiple histological variants added to this antecedent, which are usually the cause of important diagnostic doubts. For this reason, studies in which more and more morphometric procedures are added have been developed. The success of an individualized treatment depends on an accurate diagnosis, in which morphometry is recognized by ruling out subjectivity in diagnosis, becomes a valuable tool. Objective: morphometric characterization of papillary thyroid carcinoma diagnosed by excisional biopsies. Morphometric. Methods: a morphometric study of a series of cases was carried out with 12 patients with this histopathological diagnosis, attended at the Vladimir Ilich Lenin University Provincial Hospital. 340 fields were selected and 10 465 cell nuclei were measured, which was our sample. Nuclear morphometric indicators were characterized, such as area, volume and shape factor. Results: nuclear area and volume showed increased values compared to benign nodular disease values from other studies. The value of the nuclear form factor approached one, so the nuclei tend to be round and it was observed that the higher the values of the nuclear area, the higher the values of the nuclear form factor. Conclusions: morphometric indicators of papillary thyroid carcinoma were characterized in the studied cases that may contribute to histopathological diagnosis.

A este antecedente se suman las múltiples variantes histológicas que posee la enfermedad, que en ocasiones son motivo de importantes dudas diagnósticas. Por esta razón, se desarrollan estudios en los que cada vez más se añaden procedimientos morfométricos. Se reconoce que el éxito de un tratamiento individualizado depende de un diagnóstico preciso, donde la morfometría, al descartar la subjetividad en el diagnóstico se convierte en una herramienta de mucho valor. Objetivo: caracterización morfométrica del carcinoma papilar de tiroides diagnosticado por biopsias escisionales. Métodos: se realizó un estudio morfométrico de serie de casos en 12 pacientes con este diagnóstico histopatológico, atendidos en el Hospital Provincial Universitario Vladimir Ilich Lenin. Se seleccionaron 340 campos y se midieron 10 465 núcleos celulares, lo que constituyó la muestra. Se caracterizaron indicadores morfométricos nucleares del carcinoma papilar de tiroides como el área, el volumen y el factor de forma. Resultados: el área y volumen nuclear mostraron valores aumentados comparados con los valores de enfermedades nodulares benignas de otros estudios. El valor del factor de forma nuclear se acercó a uno por lo que los núcleos tienden a ser redondos y se pudo observar que a mayores valores del área nuclear mayores valores del factor de forma nuclear. Conclusiones: se caracterizaron indicadores morfométricos del carcinoma papilar de tiroides en los casos estudiados como el área, el volumen y el factor de forma que contribuyen a su diagnóstico histopatológico.

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.
