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
Hybride Zwillinge für die Entwicklung und den Betrieb von Robotik-Anwendungen
No full textThe concept of the twin became a central structuring element during the fourth industrial revolution. The term serves as a tool to mirror objects between the real world and the information world. The digital twin (DT) takes on crucial roles during the various phases of a robotic system's life cycle by replicating the real system, the real twin (RT), in cyber space as required. Two distinct DT variants emerge in the application spectrum. On the one hand, the DT lays the foundation for the use of advanced data processing methods during the engineering phase, allowing robotic systems to be designed more efficiently and flexibly at the same time. These methods are primarily used for the planning, analysis and optimization of systems and are based on physically correct simulation models. On the other hand, DTs aggregate and process a large amount of operational data throughout production in order to identify system states and interpret their progress. Among other things, specimens of this DT variant are essential for the analysis, prediction and evaluation of events in the context of predictive maintenance. However, the still widespread separation of engineering and operation means that information and knowledge is only insufficiently exchanged between the life cycle phases and the potential of a robotic system is therefore not exploited in full. Instead, an end-to-end methodology is required in order to use the DT as an integral element of modern robotic systems, which incorporates comprehensive knowledge about the system from both the engineering and operation phases into the control architecture. This way, the knowledge accumulated in the DT is available to the facility throughout its entire life cycle in order to act as an intelligent system. For the realization, it is essential to consider the DT and RT as one single entity --- the hybrid twin (HT) --- rather than two separate entities. The concept for the HT elaborated in this dissertation evolves the DT into an integral part of a modern reference architecture for advanced robotics applications. In particular, this approach pursues the goal of expanding the common practice of robot-centered programming of rigid process sequences of individual actuators to a holistic view of a system as a DT. The DT provides the knowledge required for context-sensitive information processing in order to react to events within the system in real time and actively influence the behavior of the RT. This feedback loop from the RT to the DT is what enables intelligent cyber-physical systems to be realized on the basis of an innovative implementation of the Sense-Think-Act cycle by comprehensively incorporating digital information. Due to the convergence of virtuality and reality, the HT offers new opportunities to develop, commission, and operate robotic systems. For the first time, the DT is being used consistently as part of a lifecycle-spanning DT-based systems engineering methodology. A comprehensive toolbox is now available for the realization of robotic applications, permitting ideas to be quickly implemented and tested virtually. The virtual components are then gradually replaced by their physical counterparts. This reduces the implementation effort and shortens lengthy development cycles, enabling HT to meet the requirements of current key technologies of Industry 4.0, such as the integration of modern machine learning methods. The central result of this dissertation is an architecture for hybrid twins, realizing intelligent cyber-physical systems by fusing DT and RT. To implement the innovative DT-supported Sense-Think-Act platform, hybrid twins integrate a simulation-based, real-time capable runtime environment for DT as well as suitable communication technologies for the interaction with the sensors and actuators of the associated RT. By integrating hybrid twins into the Reference Architecture Model Industry 4.0, a reference architecture and a cross-lifecycle methodology for the technical implementation of Industry 4.0-compliant cyber-physical systems based on digital twins is created. HT thus provide new foundations for DT-based development and for the DT-based operation of robotic applications. Three application scenarios from the manufacturing industry, space and forestry are presented to evaluate the developed approach

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.
