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
Vaimse arengu mahajäämuse geneetilised põhjused Eestis: fragiilne X sündroom ja kreatiini transporteri defekt
Get PDFThe present study was initiated to characterize two most common X-linked MR disorders: fragile X syndrome (FXS) and creatine transporter deficiency in Estonia.
Within years 1997 to 2006 in the Department of Genetics of United Laboratories of Tartu University Hospital there were 676 patients (516 children and 160 adults) investigated for FXS. The prevalence of FXS among the MR population in Estonia was 2.7%, which was similar to the results of previously reported studies that were performed on Caucasian males. Furthermore, the overall live-birth prevalence rate of FXS from 1984 to 2005 was 1:27,115. The clinical phenotype of the boys with FXS was similar to previously reported cases. The main clinical feature of the females with FXS premutation was premature ovarian insufficiency or irregular menstruation (43%).
In collaboration with Department of Genetics of United Laboratories of Tartu University Hospital, Children’s Clinic of Tartu University Hospital, and Tallinn Children’s Hospital DNA material and phenotype data from 83 Estonian families were collected. From this study group familial XLMR group that consist 49 families where probands in the families were mainly boys were chosen. The prevalence of creatine transporter deficiency among investigated families with suspicion of XLMR was found to be 2 %. In three related brothers and their mother a missense mutation – c.1271G>A (p.Gly424Asp) was identified. This mutation has not been previously reported. The phenotype of patients with creatine transporter defect was somewhat different from published cases and the clinical expression varied widely among affected brothers.
In addition, our aim was to evaluate the correlation between clinical features and molecular finding in cases of rare submicroscopic chromosomal aberration, which causes MR in complicated dysmorphic patients. In this study, two patients with submicroscopic copy number variation in chromosomes X and 17q were being described.
Uuringus analüüsitakse kahte sagedasemat X-liitelise vaimse arengu mahajäämuse sündroomi – fragiilse X sündroomi (FXS) ja kreatiini transporteri defekti.
FXS uuringu teostamisel võeti aluseks 1997-2006 aastal SA Tartu Ülikooli Kliinikumi Ühendlabori geneetikakeskuses teostatud FXS-i positiivsete DNA analüüside tulemused. Sel ajavahemikul oli Eestis FXS uuring teostatud 676 patsiendil (516 lapsel ja 160 täiskasvanul). FXS esinemissageduseks Eesti vaimse arengu mahajäämusega patsientide hulgas oli 2,7%, mis sarnanes esinemissagedusega vaimse arengu mahajäämusega patsientide populatsiooni kohta publitseeritud tulemustega Kaukaasia rassi meestel. Lisaks leiti FXS üldlevimus Eestis aastatel 1984-2005. See oli 1:27,115 elusalt sündinud vastsündinu kohta, mis on madalam kirjanduses publitseeritud andmetest. FXS-ga poiste kliiniline pilt oli sarnane eelnevalt kirjeldatud juhtudele. FXS premutatsiooniga naispatsientide peamiseks kliiniliseks avaldumiseks oli enneaegne ovariaalne puudulikkus või ebaregulaarsed menstruatsioonid (43%).
Koostöös SA Tartu Ülikooli Kliinikumi Ühendlabori geneetikakeskuse, Tartu Ülikooli Lastekliinikumi ja Tallinna Lastehaigla Geeneetikateenistusega koguti DNA materjal ja kliinilised andmed 83-st Eesti perest. Sellest grupist valiti 49 peret kelle perekonna anamnees viitas pärilikule X-liitelisele vaimse arengu mahajäämusele. Kreatiini transporteri defekt leiti X-liitelise vaimse arengu mahajäämuse kahtlusega perekondade seast 2%-l. Leiti üks hemisügootne punktmutatsioon – c.1271G>A (p.Gly424Asp) ühe perekonna kolmel vennal ja nende emal. Seda mutatsiooni ei ole varasemalt kirjeldatud. Selle haiguse kliiniline väljendumine oli väga erinev ühe perekonna haigestunud vendade seas ning see fenotüüp oli erinev eelnevalt publitseeritud juhtudest.
Seoses submikroskoopiliste koopiaarvu muutuste uurimisega 83-s eelnevalt mainitud Eesti peres, kirjeldatakse selles töös kahte harvaesinevat kromosomaalset muutust – kompleksset X-kromosoomi aberratsiooni ja deletsiooni 17 kromosoomi pikas õlas, ning neid muutusi kandvate patsientide kliinilist fenotüüpi

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.
