Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Analyse et modélisation des impacts du développement des énergies renouvelables intermittentes sur le système électrique Français : Etude du potentiel du stockage de l'électricité et de la complémentarité avec la chaleur
No full textLa France affiche une volonté de développer massivement les énergies renouvelables intermittentes – éolien et photovoltaïque - tout en diminuant la part des sources pilotables, ici le nucléaire. Ce changement de paradigme implique de repenser la gestion des systèmes énergétiques. En effet, l’intermittence des renouvelables génère un besoin de flexibilité à différentes échelles de temps, de la journée à l’année. Ne pouvant plus se reposer sur la flexibilité des moyens pilotables, cette thèse questionne le potentiel d’autres moyens pour y répondre : stockage d’électricité, surdimensionnement de la production et réseaux de chaleur.Face à la nécessité d’une approche système, des modèles simples ont été développés pour affiner la compréhension des interdépendances entre production et stockages. Les indicateurs optimisés sont économiques (€) mais aussi environnementaux : énergie grise et émission de gaz à effet de serre sur l’ensemble du cycle de vie. Les performances des systèmes considérés sont celles d’aujourd’hui et leur développement est limité par les ressources et l’espace disponibles. Sans rentrer dans le détail précis du fonctionnement de chaque technologie, cette approche physique donne les domaines de fonctionnement optimaux des différentes technologies, et les cas difficiles pour lesquels les solutions manquent encore.Dans un premier temps, le besoin en flexibilité généré pourdifférents taux de pénétration de l’intermittence est quantifié pour plusieurs échelles de temps. Cela permet de comparer le potentiel de différentes technologies de stockage d’électricité à chacune de ces échelles pour mettre en phase production et consommation. Les résultats montrent que les temps longs –-- typiquement le stockage saisonnier –-- sont ceux qui demandent les plus gros investissements pour une faible rentabilité. Ensuite, les mécanismes de compétition entre plusieurs stockages et le surdimensionnement sont analysés pour montrer dans quel cas les optimums utilisent des solutions complémentaires. L’étude aborde alors le potentiel du couplage entre le réseau électrique et le réseau de chaleur comme moyen de flexibilité, notamment pour la gestion des besoins longs termes.Ce travail de thèse se focalise à l’échelle Française, bien que la méthodologie soit applicable ailleurs.France aims to massively develop intermittent renewable energies --- wind and photovoltaic --- while reducing the share of dispatchable sources, in this case, nuclear power. This paradigm shift implies rethinking the management of energy systems. Indeed, renewables' variable nature generates a need for flexibility on different time-scales, from day to year. As dispatchable means' flexibility can no longer be relied on, this thesis questions the potential of other means to meet this need: electricity storage, oversized production and heating networks.Faced with the need for a systemic approach, we developed simple models to enhance the understanding of the interdependencies between production and storage. The optimized indicators are economic (€), but also environmental: embodied energy and greenhouse gas emissions over the entire life cycle. The performances of the systems considered are those of today and their development is limited by resource and space availability. Without going into the precise details of how each technology works, this physical approach points out optimal operation areas for the different technologies and the difficult cases for which solutions are still lacking.First, the need for flexibility generated for different intermittency penetration rates is quantified for several time scales. It enables us to compare the potential of different electricity storage technologies --- at each of these scales --- to bring production and consumption in phase. The results show that long time-scales --- typically seasonal storage --- require the largest investments for low profitability. The competition mechanisms between several storages and oversizing are then analyzed. It shows how the optimum solutions use complementary flexibility means. The study then addresses the potential of coupling between the electrical grid and the heating grid as a means of flexibility, particularly for the management of long-term needs.This thesis work focuses on the French scale, although the methodology is applicable elsewhere

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.
