    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    Full text link
    We 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

    Frakturen des oberen Sprunggelenks bei geriatrischen Patienten werden im Hinblick auf eine alternde Gesellschaft in Zukunft zunehmen. In einem unter starken Kostendruck stehenden Gesundheitssystem wird die ökonomische Dimension medizinischer Behandlungen immer wichtiger. Die vorliegende Studie stellt eine detaillierte Analyse der Kosten der operativen Versorgung und des stationären Aufenthalts dar. Die Faktoren, welche untersucht wurden, sind Alter, Geschlecht, Komorbiditäten, Aufenthaltsdauer, Operationsdauer und Komplikationen. Insgesamt wurde eine retrospektive Untersuchung von 345 Patienten über einen Zeitraum von 14 Jahren durchgeführt. Im Mittelpunkt des Interesses stand der Einfluss der Faktoren auf die verursachten Gesamtkosten, die Erlöse sowie der Gewinn bzw. Verlust auf individueller Patientenebene. Der Großteil der Kosten entstand durch die operative Versorgung (23,09%) und den Aufenthalt auf Normalstation (53,71%). Als unabhängige Prädiktoren für die Gesamtkosten zeigten sich das Alter, auftretende Komplikationen, eine Fixateur- externe-Anlage, ein Intensivaufenthalt, Transfusion und eine verlängerte OP- Dauer. Für höhere Erlöse konnten ebenfalls die Fixateur-externe-Anlage, Transfusion und eine verlängerte OP-Dauer als Prädiktoren identifiziert werden. Für die Gewinn- und Verlustsituation wurde die Fixateur-externe-Anlage als Prädiktor für Gewinne und ein Intensivaufenthalt, Transfusion und verlängerte OP-Dauer für Verluste beobachtet werden. In der Literatur findet sich keine vergleichbar detaillierte Kostenanalyse zu Sprunggelenkfrakturen, insbesondere keine mit einem rein geriatrischen Patientenkollektiv. Im Mittel konnte pro Patient ein Gewinn von 50,11€ erzielt werden. Die Ökonomisierung der Medizin mit der Notwendigkeit einer effizienten Ressourcenallokation wird zukünftig dafür sorgen, dass wirtschaftliche Aspekte zunehmend an Interesse gewinnen. In Verbindung mit der sich verändernden Demographie wird die geriatrische Traumatologie besonders davon betroffen sein. Da sich Komplikationen in Verbindung mit der zunehmenden Morbidität der Patienten in dieser Arbeit als signifikanter Risikofaktor für verlängerten Aufenthalt und Kostenzunahme herausgestellt hat, könnte ein standardisierter orthopädisch-geriatrischer Versorgungsansatz bei Patienten mit Sprunggelenksfrakturen eine geeignete Verbesserungsstrategie darstellen.Fractures of the upper ankle joint in geriatric patients will increase in the future in consideration of an aging society. In a health care system under strong cost pressure, the economic dimension of medical treatments becomes more and more important. The present study presents a detailed analysis of the costs of surgical care and inpatient stay. The factors that were investigated were age, gender, comorbidities, length of stay and complications (ANGIO; OP DAUER). A total of 345 patients were retrospectively studied over a 14-year period. The focus of interest was the impact of factors on total costs incurred, revenue, and profit or loss at the individual patient level. The majority of costs were due to surgery (23.09%) and stay in normal ward (53.71%). Independent predictors of total costs were age, complications, external fixator, intensive care unit stay, transfusion, and prolonged duration of surgery. External fixator, transfusion, and prolonged duration of surgery were also identified as predictors of higher revenues. For the profit and loss situation, the external fixator was observed as a predictor for profits, and an intensive care stay, transfusion, and prolonged surgery duration for losses. No comparably detailed cost analysis on ankle fractures can be found in the literature, especially none with a purely geriatric patient population. On average, a profit of 50.11€ could be achieved per patient. The economization of medicine with the need for an efficient allocation of resources will ensure that economic aspects will gain increasing interest in the future. In conjunction with changing demographics, geriatric traumatology will be particularly affected. Since complications associated with increasing patient morbidity have been shown in this work to be a significant risk factor for prolonged stay and cost increase, a standardized orthopedic geriatric care approach for patients with ankle fractures may represent a suitable improvement strategy

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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 text
    We 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 text
    In 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.
