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

Exploring Security Practices in Infrastructure as Code: An Empirical Study
Full text linkRÉSUMÉ: L’infonuagique est populaire en partie parce que les outils d’Infrastructure as Code (IaC) permettent d’utiliser des scripts facilitant la gestion et configuration d’infrastructures dans le cloud. Cependant, rien dans le processus de création de scripts n’empêche automatiquement les ingénieurs ou les développeurs d’appliquer des configurations erronées, introduisant des vulnérabilités ou des risques pour la sécurité et le respect de la vie privée. La sécurité dépend de leur compréhension et de l’application de politiques, de directives ou de bonnes pratiques explicites. Ce mémoire analyse la mise en oeuvre réelle, par les ingénieurs et les développeurs, des bonnes pratiques en matière de sécurité dans les scripts IaC. Nous avons collecté 121 extraits de configuration Terraform pour AWS et les avons analysés afin de catégoriser les bonnes pratiques. Ensuite, nous avons mené une étude empirique sur 401 projets GitHub impliquant des infrastructures AWS décrites via Terraform, afin d’étudier l’adoption des bonnes pratiques dans de véritables projets. Les résultats montrent qu’un manque de chiffrement et un manque de l’utilisation de log et de surveillance des ressources sont les défauts de configuration les plus fréquents dans les fichiers Terraform pour AWS. En revanche, les failles admin par default (c’est-à-dire l’octroi par défaut de privilèges administrateurs à tous les utilisateurs) ainsi que les secrets en clair sont rares. Pour déterminer si les résultats obtenus dans la première expérience sont universels et applicables à d’autres fournisseurs populaires de cloud public, nous avons étendu notre étude à Azure (84 politiques de sécurité, 137 projets) et Google Cloud (82 politiques, 274 projets). La comparaison de l’adoption des bonnes pratiques entre les fournisseurs généralise les résultats en matière de Politiques d’accès et l’absence de Secrets en clair, tout en soulignant l’impact des choix de conception des services cloud sur l’adoption des pratiques de sécurité par le biais des configurations par défaut. Enfin, une deuxième expérience a permis d’explorer les corrélations potentielles entre les mesures de popularité des projets et l’adoption des bonnes pratiques de sécurité. Grâce à une analyse statistique, une corrélation a pû être trouvée entre le nombre d’étoiles d’un projet GitHub et l’adoption des pratiques dans son infrastructure cloud, mais pas nécessairement par le biais des forks et/ou du nombre de contributeurs. Sur la base de notre étude, nous proposons des lignes directrices aux praticiens de l’infonuagique afin de limiter la vulnérabilité des infrastructures. ABSTRACT: Cloud computing is popular in part because Infrastructure as Code (IaC) tools let us use convenient scripts to manage and configure cloud infrastructure. However, nothing in the scripting process automatically prevents engineers or developers from pushing misconfigurations; introducing vulnerabilities or privacy risks. Security depends on their understanding and application of explicit policies, guidelines, or best practices. This thesis analyzes engineers’ and developers’ real-world implementation of IaC scripted security best-practices through two experiments. First, we collected 121 AWS Terraform configuration snippets from recognized catalogs and analyzed them in order to categorize best practices. Then, we conducted an empirical study of 401 GitHub projects involving Terraform AWS infrastructures, to measure the actual adoption of the security configuration previously collected. The results show that a lack of encryption and a lack of logging and resource monitoring are the most neglected security best-practices in AWS Terraform files. By contrast, admin by default (i.e., granting administrative privileges to all users by default) and hard-coded secrets misconfigurations are rare. To investigate whether the results obtained in the first experiment are universal and applicable to other popular public cloud providers, we expanded our study to include Azure (84 security policies, 137 real-world projects) and Google Cloud (82 policies, 274 projects). Comparing the adoption of best practices between providers generalizes findings in Access policies and the absence of Hard-coded secrets, while highlighting the impact of cloud services design on security practice through default configurations. Finally, a second experiment explores potential correlations between the popularity metrics of repositories and the adoption of security best practices. Through statistical analysis, a correlation can be found between a repository number of stars and the adoption of practices in its cloud infrastructure, but not necessarily through forks and contributor numbers. Based on our investigation, we offer guidelines for cloud practitioners to limit infrastructure vulnerability
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.
