Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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
Subtractive machining with industrial robots in timber construction : parameter studies, increase in efficiency and system integration
No full textDer Anteil des Holzbaus im Bauwesen nimmt weltweit zu, unter anderem aufgrund des Potentials den Umwelteinfluss zu reduzieren. Gleichzeitig ist die Bauindustrie mit einem Mangel an qualifizierten Arbeitskräften konfrontiert. Dies führt zur steigenden Nachfrage und letztlich zu der Notwendigkeit, die Effizienz der Produktionsprozesse zu verbessern.Ein Ansatz ist die Digitalisierung der Prozesskette sowie die Einführung neuer Produktionsmethoden. Die Bearbeitung von Brettschichtholzträgern erfolgt derzeit mit Abbundmaschinen. Eine mögliche Ergänzung bestehender Anlagen stellen Industrieroboter dar. Das Ziel dieser Arbeit ist die Untersuchung von Industrierobotern zur Steigerung der Produktionseffizienz bei der subtraktiven Bearbeitung von stabförmigen Brettschichtholzbauteilen. Dazu werden zunächst der Stand der Technik und das Potenzial von Industrierobotern, analysiert. Im Anschluss erfolgen Versuche zur Maßgenauigkeit und Oberflächenqualität von Abbundanlagen und insbesondere von Industrierobotern. Daraufhin wird die maximale Ausnutzung des Arbeitsraums des Roboters durch ein System zur Werkstück-Positionierung untersucht. Abschließend erfolgen die Programmierung eines Bauteilstapelmodells und Stapelbearbeitung zur Reduktion der Bearbeitungszeit. Die Analyse zeigt, dass die Anwendbarkeit von Industrierobotern zur subtraktiven Bearbeitung vom Endeffektor abhängt. Die resultierende Maßgenauigkeit und Oberflächengüte wird als ausreichend und konkurrenzfähig zu Abbundanlagen eingestuft. Der Vorteil des großen Arbeitsraums des Industrieroboters kann genutzt werden, ohne dass die Maßgenauigkeit auf ein inakzeptables Niveau sinkt. Dadurch eröffnen sich Möglichkeiten zur Stapelbearbeitung oder Nutzung mobiler Roboterplattformen. Darüber hinaus wurde zur Verbesserung der Bearbeitungseffizienz ein Modell zur Erstellung von Werkstückstapeln entwickelt, das zu einer Reduzierung der Bearbeitungszeit um bis zu 16 % im Vergleich zur Einzelbearbeitung führt.The share of timber construction has been growing worldwide for several years, among others because of its potential to decrease the environmental. At the same time, the construction industry is facing a shortage of skilled labour. These factors are leading to increased demand and, the need to improve the efficiency of production processes. One approach is the digitalisation of the process chain and the implementation of new production methods. The processing of glued laminated timber beams is currently carried out by joinery machines. One potential addition to the range of machines are standard multi-axis industrial robots. The overall aim of the thesis is to investigate whether and to what extent robotics can lead to an increase in production efficiency when machining timber construction elements. The conducted studies of this thesis at BOKU focused on milling operations. The investigations consist of several steps, starting with the analysis of the state of the art and possibilities offered by industrial robots. This is followed by machining trials to evaluate a benchmark joinery machine and, in particular, industrial robot in terms of dimensional accuracy and surface quality. Subsequently, a study of workspace utilisation by introducing workpiece location systems is conducted and the modelling and machining of multi-part stacks is achieved. The analysis showed that the applicability of industrial robots for machining tasks is highly dependent on the end-effector. The resulting dimensional accuracy and surface quality was found to be sufficient and competitive with joinery machines. The advantageously large workspace of industrial robot's was successfully exploited without reducing the machining accuracy to unacceptable levels, opening up future opportunities. To further improve machining efficiency, a model for creating optimal workpiece stacks was introduced, resulting in a reduction in machining time of up to 16% compared to individual machining.submitted by Marc PantscharowitschDissertation BOKU University 202
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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.
