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
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

Aufdeckung von Herausforderungen und Chancen im Bereich der Fahrradsicherheit durch Crowdsourcing
No full textAn increased modal share of bicycle traffic is a key mechanism to reduce emissions and solve traffic-related problems. However, a lack of comfort and (perceived) safety keeps people from using their bicycles more frequently. To improve comfort and safety in bicycle traffic, city planners need (a), an overview of accidents, near miss incidents, and bike routes, (b), an overview of the cycling infrastructure's maintenance state, and (c), a way to study the effect of potential changes in the cycling infrastructure before implementing them in the real life. However, these needs, which are also of interest to cyclists and policy makers, are currently not being met satisfactorily.
In this thesis, we present three main contributions to solve these problems. First, we show SimRa, a crowdsourcing-based citizen science project to record cycling trips and near miss incidents. As part of this contribution, we also present CycleSense, an approach based on Deep Learning to automatically detect near miss incidents from recorded cycling trip data. Knowing the hazardous bicycle traffic hotspots, policy makers and city planners can approve and implement safety improvements for cyclists. Cyclists, on the other hand, can use this information to circumvent these spots. Second, we describe an approach for deriving the road surface quality from cycling trip data. Our approach uses data produced by the inertial measurement unit of the smartphone to calculate the smoothness of the road surface from the vibrations caused by traversing on the road with a bicycle. We then show how our approach can easily be integrated into a cycling trip recording app with SimRa as a case study. This contribution also contains a visualization of the cycling infrastructure's smoothness and helps policy makers, city planners and cyclists in the same way as our first contribution.
Third, we improve the cyclist simulation model of the urban traffic simulation software SUMO. For this, we first show that the default cyclist model of SUMO is not realistic by comparing it to cyclist behavior in the SimRa dataset. We then split the cycling trips in the SimRa dataset into three parts for slow, medium, and fast cyclists and implement our findings as a plugin that can be added to SUMO for a more realistic cyclist simulation. This new cyclist simulation can provide a strong tool for city planners to better to study effects of potential changes in the traffic infrastructure.Eine Erhöhung des Fahrradverkehrs trägt zur Verringerung der Treibhausgasemissionen und zur Lösung verkehrsbedingter Probleme bei. Mangelnder Komfort und (gefühlte) Unsicherheit halten die Menschen jedoch davon ab, öfter Fahrrad zu fahren. Um den Komfort und die Sicherheit im Radverkehr zu erhöhen, benötigen Stadtplanende (a) einen Überblick über Unfälle und Gefahrensituationen, (b) einen Überblick über den Wartungszustand der Radverkehrsinfrastruktur und (c) eine Möglichkeit, die geplanten Änderungen an der Radverkehrsinfrastruktur zu testen, bevor sie umgesetzt werden. In dieser Arbeit präsentieren wir drei Beiträge zur Lösung dieser Probleme.
Zunächst stellen wir SimRa vor, ein Crowdsourcing-basiertes Citizen-Science-Projekt zur Erfassung von Gefahrensituationen im Radverkehr. Im Rahmen dieses Beitrags stellen wir auch CycleSense vor, einen auf Deep-Learning basierenden Ansatz zur automatischen Erkennung von Gefahrensituationen aus aufgezeichneten Radfahrdaten. Stadtplanende und politische Entscheidungstragende können die mit SimRa aufgedeckten gefährlichen Stellen im Radverkehr mit Baumaßnahmen verbessern. Radfahrende können diese Informationen nutzen, um diese Stellen zu umfahren.
Im zweiten Beitrag beschreiben wir, wie wir die Straßenoberflächenqualität aus Fahrradfahrtdaten ermitteln. Dazu verwenden wir Daten, die von den Bewegungssensoren des Smartphones erzeugt werden, um Unebenheiten der Straßenoberfläche anhand der Fahrtvibrationen zu berechnen. Wir zeigen am Beispiel der SimRa-App, wie unser Ansatz in eine App zur Aufzeichnung von Fahrradrouten integriert werden kann. Dieser Beitrag enthält auch eine Visualisierung der Ergebnisse und hilft sowohl Stadtplanenden als auch Radfahrenden.
Im dritten Beitrag verbessern wir das Radfahrersimulationsmodell der Verkehrssimulationssoftware SUMO. Wir zeigen die Schwächen des Radfahrermodells von SUMO, indem wir es mit dem Verhalten von Radfahrenden im SimRa-Datensatz vergleichen. Anschließend teilen wir die Radfahrten im SimRa-Datensatz in drei Teile für langsame, mittlere und schnelle Radfahrende auf und implementieren einen realistischeres Modell für SUMO. Dies kann ein starkes Werkzeug für Stadtplanende sein, um ihre geplanten Änderungen an der Verkehrsinfrastruktur besser zu testen
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.
