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
Analysis of digitization methods for edentulous jaws
Get PDFThis study evaluated the trueness and precision of direct digitization and indirect digitization of an edentulous maxilla.
An edentulous jaw model made of PEEK, featuring four hemispherical geometries on the alveolar ridge, served as the testing model. The PEEK model was industrially digitized to obtain a reference dataset (REF). Subsequently, the model was digitized according to the clinical workflow (n=25/group) with the following IOS: Cerec Primescan AC (PRI); Trios 3 Wireless (TRS); True Definition (TRD); iTero Element (ITE); Cerec AC Omnicam (OMN). In addition, conventional impressions were taken with scannable PVS (Flexitime Fast&Scan light flow and Flexitime Monophase Pro Scan) and scanned (n=25/group) with laboratory scanners: D810 (D8I) and In EOS X5 (E5I). The impressions were poured, and the resulting stone casts were scanned (n=25/group) with D810 (D8M) and In EOS X5 (E5M). Linear and angular parameters were measured in the virtual model data and compared to REF.
One-way ANOVA detected significant differences for all tested parameters. The highest trueness in the P17-P13 and the P17-P23 distances was revealed by group E5I, and in the P17-P27 distance by group PRI. Regarding angular parameters in the transverse plane group, D8M showed the best trueness with no significant difference to any other group, while in the sagittal plane E5M exhibited the highest trueness. Group D8I was most precise in all linear parameters and angle XZ, while group E5I exhibited the highest precision in angle YZ.
Digitization of conventional impressions presented the most accurate results. PRI demonstrated values similar to impression digitization and superior to stone cast digitization, while TRS and OMN performed similarly to stone cast digitization.Diese Studie bewertete die Richtigkeit und Präzision direkter und indirekter Digitalisierung eines zahnlosen Oberkiefers. Als Testmodell diente ein zahnloses Oberkiefermodell aus PEEK mit vier halbkugelförmigen Geometrien am Kieferkamm. Das PEEK-Modell wurde industriell digitalisiert, um einen Referenzdatensatz (REF) zu erhalten. Anschließend wurde das Modell mit folgendem IOS digitalisiert (n=25/Gruppe): Cerec Primescan AC (PRI); Trios 3 Wireless (TRS); True Definition (TRD); iTero-Element (ITE); Cerec AC Omnicam (OMN). Darüber hinaus wurden konventionelle Abformungen mit scanbarem PVS (Flexitime Fast&Scan light flow und Flexitime Monophase Pro Scan) aufgenommen und mit Laborscannern: D810 (D8I) und In EOS X5 (E5I) gescannt (n=25/Gruppe). Die Abformungen wurden gegossen und die resultierenden Gipsmodelle wurden gescannt (n=25/Gruppe) mit: D810 (D8M) und In EOS X5 (E5M). Lineare und Winkelparameter wurden gemessen und mit REF verglichen. Die Einfaktorielle-ANOVA stellte signifikante Unterschiede für alle getesteten Parameter fest. Die höchste Richtigkeit in den Distanzen P17-P13 und P17-P23 wurde von Gruppe E5I und in der Distanz P17-P27 von Gruppe PRI gezeigt. Hinsichtlich der Winkelparameter in der transversalen Ebene zeigte Gruppe D8M die beste Richtigkeit ohne signifikanten Unterschied zu anderen Gruppen, während E5M in der Sagittalebene die höchste Richtigkeit aufwies. Gruppe D8I war in allen linearen Parametern und im Winkel XZ am präzisesten, während Gruppe E5I die höchste Präzision im Winkel YZ aufwies. Die Digitalisierung konventioneller Abformungen lieferte die genauesten Ergebnisse. PRI zeigte ähnliche Werte zur Digitalisierung von Abformungen und war der Digitalisierung von Gipsmodellen überlegen, während TRS und OMN ähnliche Leistungen wie die Digitalisierung von Gipsmodellen zeigten

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.
