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

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.

Intégration de solution blockchain dans un système global de traçabilité d’une usine opérationnelle
No full textIndustry 4.0 involves major changes in manufacturing process management. Both the Internet of Things and cloud computing allow online interactions between third parties, such as providers, customers and suppliers, with the tracceability system of a factory. The industrial blockchain offers a paradigm that makes it possible to set up an unfalsifiable register of transactions involving several partners, individually free to register actions and to verify the actions of others on an ad hoc basis. In this sense, it makes it possible to set up reliable, transparent and directly verifiable traceability by each partner (supplier/factory, factory/subcontractor, factory-customer, etc.). In the era of connected factories, it is a solution that can be implemented between the factory's information system and the various partners to automate traceability management. However, the plant's overall traceability system may include internal components with strong implications on confidentiality, and whose link with traceability lies only with the plant and not with its partners. In this context, the transparency would be obtained to the detriment of data confidentiality. In addition, the evaluations proposed on the blockchain often focus on its own performance rather than on its impact on the industrial system, which is one of the obstacles to its massive adoption. This thesis work aims to develop an architecture and propose changes to traceability systems in order to allow the integration of a blockchain solution intended to guarantee traceability in full transparency between the factory and the partners without compromising the confidentiality. Firstly, an inventory of the factory will be presented regarding cybersecurity, thus introducing our contribution to a division of the factory in the form of perimeters which will guide our synthesis of good practices regarding the manufacturing system security. Then, we define a product-centered traceability approach underlining the implication of the partners as well as a categorization of the data according to their criticality. The presentation of the blockchain architecture will come in a third step along with its implementation using the Multichain platform as well as a discussion on its resource consumption, such as energy and storage volume related to the blockchain solution. Finally, a discrete event modeling that can be adapted to any manufacturing factory plant will be proposed in order to analyze the impact of a blockchain solution on the overall factory plant, according to different metrics such as storage volume needsn energy consumption, and environmental impact.L'industrie 4.0 implique des changements majeurs dans la gestion des processus de fabrication. L'internet des objets et le cloud computing permettent des interactions en ligne entre des tiers, tels que des clients et des fournisseurs, avec le système de traçabilité d'une usine. La blockchain industrielle offre un paradigme qui permet de mettre en place un registre infalsifiable de transactions impliquant plusieurs partenaires, individuellement libres d'y inscrire des actions et de vérifier les actions des autres de manière ad hoc. En ce sens, elle permet de mettre en place une traçabilité fiable, transparente et directement vérifiable par chaque partenaire (fournisseur/usine, usine/sous-traitant, usine-client, etc.). A l'ère des usines connectées, elle constitue une solution qui peut être mise en oeuvre entre le système d'information de l'usine et les différents partenaires pour automatiser la gestion de la traçabilité. Néanmoins, le système global de traçabilité de l'usine peut comporter des composants interne avec des implications fortes sur la confidentialité et dont le lien avec la traçabilité n'incombe qu'à l'usine et pas à ses partenaires. Dans ce contexte, la transparence apportée se ferait au détriment de la confidentialité des données. De plus, les évaluations proposées sur la blockchain portent en général sur ses performances en tant que technologie, plutôt que sur son impact global sur le système industriel, ce qui peut être un frein à son adoption. Ce travail de thèse vise à développer une architecture et proposer des évolutions des systèmes de traçabilité pour permettre l'intégration d'une solution blockchain destinée à garantir la traçabilité entre l'usine et les partenaires sans qu'il n'y ait compromission de la confidentialité au motif de la transparence. Dans un premier temps, un état des lieux de l'usine sera présentée sous l'angle de la cybersécurité avec pour contribution une division de l'usine sous forme de périmètres en vue d'aboutir à une synthèse de bonnes pratiques adaptées à chaque périmètre en matière de sécurité informatique. Ensuite, nous définissons une approche de traçabilité centrée sur le produit soulignant l'implication des partenaires ainsi qu'une catégorisation des données selon leur criticité, ce qui permet de gérer leur accès et leur stockage au niveau des différents partenaires ainsi que dans l'infrastructure de l'usine. La présentation de l'architecture blockchain viendra dans un troisième temps avec une implémentation via la plateforme Multichain ainsi qu'une discussion sur la consommation en terme énergétique mais également en termes de stockage de la blockchain. Enfin, une modélisation à évènement discret pouvant être adaptée à n'importe quelle usine de production industrielle est également proposée afin d'analyser l'impact d'une solution blockchain sur une usine opérationnelle en fonction de différentes métriques telles que les besoins en capacité de stockage, la consommation d'énergie et l'impact environnemental
