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
Metaanalyse und systematischer Review zur Arthritis bei Patienten mit systemischer Sklerodermie
Get PDFDie systemische Sklerodermie gehört zu den Kollagenosen und ist gekennzeichnet durch eineVerdickung der Dermis sowie durch eine Beteiligung innerer Organe. Im Weiteren stellenBeschwerden der peripheren Gelenke eine typische Manifestation der SSc dar, wobeientzündliche Gelenkmanifestationen und deren Häufigkeit kontrovers diskutiert werden. DiePrävalenz einer entzündlichen Gelenkmanifestation und deren Schwere sind bisher nurunzureichend geklärt. Aus diesem Grund erfolgte als Grundlage dieser Arbeit dieDurchführung eines systematischen Reviews und einer Metaanalyse zur Evaluation derHäufigkeit einer arthritischen Manifestation der SSc.Das Literatur Online-Portal PubMed wurde nach Studien zur Arthritis bei SSc durchsucht.Die Suche wurde mit Fachbegriffen (z.B. Sklerodermie, systemische Sklerose, Arthritis,Hand- und Fußbeteiligung) in verschiedenen Kombinationen durchgeführt. Originalartikel,die nicht in englischer Sprache verfasst wurden und Artikel, deren Thema sich nicht mit derArthritis in Zusammenhang mit SSc befasste, wurden ausgeschlossen. Eingeschlossen wurdenPublikationen in denen die untersuchten Patientenkohorten entsprechend der ACR oderLeRoy Kriterien eingeschlossen wurden und in denen die Arthritis nach klinischen undradiologischen Gesichtspunkten untersucht wurde. Die Arbeiten wurden von zweiunabhängigen Untersuchern gelesen und bewertet.Basierend auf dem Random-effect Modell wurde in einer Metaanalyse von sieben Arbeiteneine Prävalenz 26 % (95 % KI[16.7, 36.1]) nach radiologischen und eine Prävalenz von 23 %(95% KI[14.9, 30.9]) nach klinischen Gesichtspunkten ermittelt. Interessant ist, dass keinUnterschied im Auftreten einer peripheren Arthritis nach radiologischen (OR=1.1, 95%KI[0.47,2.57]) oder klinischen (OR= 1.11, 95% KI[0.6,2.05]) Gesichtspunkten in derSubtypenanalyse der lcSSc gegenüber der dcSSc errechnet werden konnte.Die systematische Untersuchung der bis dato publizierten Arbeiten zur peripherenGelenkbeteiligung bei SSc machen deutlich, dass die von den Patienten beklagtenGelenkbeschwerden nicht alleine über eine Arthrose oder Veränderungen der Dermis zuerklären sind. Vielmehr muss differentialdiagnostisch auch eine arthritische Genese derBeschwerden bedacht werden. Nach den hier vorgelegten Daten ist die Prävalenz für eineArthritis bei SSc höher einzuschätzen als die einer PAH.Systemic sclerosis (SSc) is a connective tissue disease characterised by excessive thickeningof the dermis and in addition affection of internal organs. During the clinical course of diseasemany patients experience a musculoskeletal involvement; however, true arthritis is describedas a very rare manifestation in textbooks. Currently, the frequency and severity ofinflammatory joint disorders are insufficiently recorded and evaluated. Therefore thisassignment represents a metaanalysis (and systematic review) in which the frequency ofmanifestation of peripheral arthritis in SSc patients was determined based on clinical andradiological data.A systematic literature search using PubMed was performed to find studies on arthritis in SScpatients. The search terms were sclerodema, systemic sclerosis, arthritis, inflammatory jointdisease, hand involvement, foot involvement and musculoskeletal findings in variouscombinations. Original articles not written in English and articles which were not dealing witharthritis in SSc patients were excluded from the study. Articles were included in which theexamined cohorts correspond to the ACR- or LeRoy criteria for SSc and arthritis wasdiagnosed based on clinical and/ or radiological data. All manuscripts were read and reviewedby two independent investigators.In a metaanalysis of 7 studies a prevalence of 26 % (95 % CI[16.7, 36.1]) for radiologicallydetectable arthritis in SSc patients was found based on the random-effect model. For clinicalarthritis, the prevalence was calculated to be 23 % (95% CI[14.9, 30.9]). Of interest, nodifference in the occurence of arthritis in diffuse and limited SSc was observed radiologically(OR=1.1, 95% CI [0.47,2.57]) or clinically (OR= 1.11, 95% CI [0.6,2.05]).The screening of recent publications reveals that an involvement of peripheral joints in SScpatients cannot be explained solely by destructive changes or alterations of the dermis and theconnective tissue. Rather a true arthritis has to be recognized as a possible organmanifestation of SSc. Finally it is pointed out that the occurrence of true arthritis in SSc isfound more frequent than the manifestation of PAH
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

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.
