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
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
Schaukelinstabilität starrer Blöcke auf einem kleinen Podest
Während sich die meisten Studien, die sich mit Erdbeben befassen, auf das Verhalten von strukturellen Bauteilen eingehen, gehen wenige auf die Instabilität von nicht befestigten oder freistehenden Bauteilen, die den Erdbeben ausgesetzt sind, ein. Solche Strukturen sind bei moderaten oder starken Erdbeben sehr anfällig für Schäden, wie zahlreiche Ereignisse in der Vergangenheit gezeigt haben. Diese Diplomarbeit behandelt Statuen auf einem Podest, Krankenhausgeräte, sowie zahlreiche mechanische und elektrische Geräte, die für die Nutzung von Gebäuden notwendig sind. Diese nicht befestigte, freistehende Zweikörperstrukturen wurden in dieser Diplomarbeit mit zwei starren übereinander angeordneten Blöcken modelliert. Ziel der Diplomarbeit war es, den Einfluss der Statuengeometrie und Schlankheit sowie das Vorhandensein des Sockels auf die Schwinganfälligkeit solcher Strukturen zu bestimmen. Die Bewegung der freistehenden, nicht befestigten Strukturen, die in alle Richtungen einer seismischen Erregung ausgesetzt sind, ist eine Kombination aus Rotieren, Gleiten und Kippen. Jeder Antwortzustand wird mit einem System stark nichtlinearer Differentialgleichungen geregelt. Die Anzahl den herrschenden Bewegungsdifferentialgleichungen nimmt exponentiell zu, wenn diese Strukturen in einer gestapelten Weise angeordnet werden. Es wäre wünschenswert, diese zusammen zu untersuchen, aber mit so vielen Komponenten würde es den Rahmen dieser Diplomarbeit sprengen. Daher konzentriert sich diese Arbeit auf die Reaktion von starren Körpern, die große Reibungskoeffizienten in ihrer Basis und zwischen Körpern haben, um jegliche andere Bewegung außer dem Kippen auszuschließen. Dies kann das ungünstigste Szenario für viele fragile Objekte (z.B. Vase in einem Museum, historische Statuen) oder für solche, bei denen in kritischen Komponenten (z.B. medizinische Geräte, Server) mechanische Schäden auftreten können, sein. Mit dieser Einschränkung kann das Systemverhalten anhand von vier möglichen Mustern beschrieben werden. In dieser Arbeit wird ein Versuch beschrieben, bei dem die seismische Reaktion eines Paares unverbundener Holzblöcke untersucht wurde. Das System bestand aus dem oberen Block (Statue) und dem Unteren (Podest). Der Versuch wurde so aufgebaut, dass nur Kippen erlaubt war. Zu den experimentellen Variablen gehörten die Geometrie des Oberkörpers, die Eingangsbewegung, sowie das Vorhandensein des Podests. Drei verschiedene Statuen wurden vier historischen Erdbeben (1976 Friuli, 1995 Kobe, 1986 Loma Prieta und 1994 Northridge) ausgesetzt. Darüber hinaus wurden die Statuen sowohl mit als auch ohne Podest getestet, um ein tieferes Verständnis der Wirkung des Podests zu ermöglichen. In jedem Experiment wurde die maximale Beschleunigung ermittelt, die zum Umstürzen führt.While most studies in civil engineering, which deal with earthquakes, are directed toward the behavior of structural elements, significantly fewer deal with the instability of unattached or freestanding structures subjected to seismic excitation. These structures are however, highly susceptible to damage during moderate or strong earthquakes, as evidenced during numerous past events. In the context of this thesis these structures are statues atop a pedestal, hospital equipment, as well as numerous mechanical and electrical equipment, which provide services to the building. This thesis deals with these unattached, freestanding dual-body structures, modeled with two rigid blocks stocked one atop of the other. The aim of the thesis is to determine the influence of the statue geometry and slenderness, and the presence of the pedestal on the rocking vulnerability of such structures. The motion of the freestanding, unattached structures, subjected to seismic excitation in all directions, is combination of rotating, sliding and jumping. Each response state is governed with a set of highly non-linear differential equations. The number of governing differential equations of motion increase exponentially when these objects are placed in stacked combination. To study all patterns combined would be desirable, but with so many components it is beyond the scope this thesis. Therefore, this thesis focuses on the response of rigid bodies with friction coefficients, in their base and between bodies, large enough so that any other motion except rocking is excluded. This may represent the worst case scenario for many fragile object (e.g. vases in a museum, historical statues) or for objects that may experience mechanical damage in critical components (e.g. medical equipment, servers). With this restriction, system behavior can be described in terms of four possible patterns, where the equations describing the rocking response are derived for each pattern. This thesis also details a shake table test, in which the seismic response of a pair of wooden, unattached blocks was evaluated. The system consisted of a top block (statue) and a lower block (pedestal). The experiment was designed in such a way, that only rocking is allowed. Experimental variables included geometry of the top body, input motion, as well as presence of the pedestal.Three different statues were subjected to twelve input motions. Namely, four input motions corresponding to the earthquakes 1976 Friuli, 1995 Kobe, 1986 Loma Prieta, and 1994 Northridge, and input motions derived from these earthquakes were used. Furthermore, blocks were tested both in a stacked configuration and as a single body, allowing deeper understanding of the effect of the pedestal. Maximum acceleration that leads to overturning was determined in every test
Dispelling the Myths Behind First-author Citation Counts
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
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
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.
