    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” 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

    Adaptive multi-path routing for internet traffic engineering

    Die vorliegende Arbeit stellt das Adaptive Multi-Path Routing (AMP) als einen neuen Algorithmus für dynamisches Traffic Engineering im Internet vor. Das Hauptziel des AMP besteht darin, die Last innerhalb einer Netzdomäne dynamisch zu verteilen, um die überlasteten Verbindungen und Pfade in Realzeit, entsprechend der momentanen Verkehrssituation und den vorhandenen Ausweichmöglichkeiten, zu entlasten. Im Gegensatz zu verwandten Ansätzen, die den Verkehr auf mehrere Pfade aufteilen, führt AMP als seine wichtigste Innovation die Einschränkung der Lastsignalisierung auf den lokalen Umkreis einer Verbindung ein und ermöglicht somit sowohl eine Verringerung der Signalisierungslast, als auch des Speicherbedarfs in den Routern. Dabei ist hervorzuheben, dass AMP trotz seiner lokalen Signalisierungsarchitektur eine globale Ausbreitung der Lastinformation innerhalb der gesamten Netzdomäne ermöglicht und so zu einer effizienten Behandlung von Überlastsituationen im Netz führt. Darüber hinaus stellt diese Arbeit sowohl einen ausführlichen Überblick über die relevante Theorie und die daraus abgeleiteten Ansätze vor, als auch eine tiefgehende Leistungsbewertung des Algorithmus in zwei unterschiedlichen Simulationsumgebungen, die IP-Netze entweder auf Paket- oder auf Flussebene abbilden, und in denen jeweils die gesamte Funktionalität von AMP implementiert wurde. Die untersuchten Simulationsszenarien stellen dabei den letzten Stand der Technik dar, indem ausgeklügelte Topologie- und Verkehrsmodelle verwendet werden, um eine hohe Übertragbarkeit der Erkenntnisse in die Realität zu ermöglichen. Die Ergebnisse der durchgeführten Leistungsbewertung demonstrieren in konsistenter Weise die Effizienz der durch AMP erzielten Lastverteilung, und sie unterstreichen auch das stabile Verhalten des Algorithmus in allen untersuchten Szenarien. Anschließend wird in einer etwas allgemeineren Betrachtung die momentane Bedeutung von Traffic Engineering im aktuellen Kontext der IP-Netze diskutiert, wonach zum Schluss noch wichtige potentielle Anwendungsgebiete für AMP im Bereich von neuen Netzlösungen und -architekturen dargestellt werden.The present thesis proposes Adaptive Multi-Path routing (AMP) as a novel algorithm for dynamic traffic engineering in the Internet. The main objective of AMP is to distribute load within a network domain in a continuous manner, trying to offload congested links and paths by responding to the observed traffic conditions in real-time. In contrast to similar multi-path routing proposals, the central innovation of AMP lies in the restriction of the exchange of load information to a local scope, thus achieving a significant reduction of signaling overhead and memory consumption in the routers. Most importantly, in spite of its local nature, AMP's signaling mechanism nevertheless enables global propagation of congestion information, leading to an efficient handling of overload events in the network. Apart from providing an extensive overview of the related theory and approaches, this thesis introduces and discusses AMP in depth, after which an exhaustive performance evaluation of the algorithm is presented. This evaluation is carried out using two distinct simulation environments, which model IP networks either at the level of individual packets or individual flows, and for both of which the full functionality of AMP has been implemented in detail. Furthermore, the investigated simulation scenarios represent the state-of-the-art concerning the choice of topologies and traffic models, thus offering a comprehensive insight into the algorithm's behavior in real systems. The results of the performance evaluations consistently demonstrate AMP's efficiency in terms of load balancing performance, and they also underline the stable behavior of the algorithm throughout the investigated scenarios. Finally, the thesis discusses traffic engineering in the current context of IP networks on a more general level, before it presents important potential areas of application for AMP in novel and emerging networking solutions and architectures

    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

    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.
