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

Etat des lieux des connaissances et production de ressources génomiques en appui à la conservation et la traçabilité du commerce illégal des pangolins
No full textPangolins (Pholidota) are a group myrmecophagous mammals consisting of eight extant species, four in Asia and four in Africa. They are considered the most heavily trafficked mammals in the world, a label that along with that of an unfounded COVID-19 intermediate host, has placed pangolins in the public and conservation spotlight. Despite this, knowledge on pangolins is limited and there are yet to be resources and tools in place to guide efficient conservation action. Providing these resources to guide investment in research priority areas, delineate conservation units for management, as well as to identify trafficking source regions and routes is key to reducing the over-reliance of international regulation which has had limited effect on the pangolin trade. Our aim is thus to provide an overview of knowledge on pangolins and generate resources to direct future conservation research through a systematic review, as well as to develop the basis for efficiently managing populations and tracing the pangolin trade using molecular techniques.In the first chapter, we aimed to systematically review research gaps and dynamics on pangolins, the major drivers of public interest in them, and their commercial exploitation through patented products. These three lines of investigation were then combined to suggest holistic research and conservation action guidelines for better conserving pangolins at a time when the world turned its attention to them. The second chapter revolved around understanding the global evolutionary framework among Pholidota, and the conservation implications thereof, by generating and analyzing whole-genomes of all extant species. We assessed pangolin phylogeny, divergence estimates, and ancient gene flow, along with per species demographic history and genome-wide diversity. We clarified the existence of a potentially new Asian pangolin species, provided genomic resources for extant species of Pholidota and a list of orthologous genes ranked by diversity to aid in conservation genetic and forensic endeavors. The third chapter focused on identifying within-species populations and potential admixture across the geographical range for each pangolin species in order to upscale resources for conservation genetics and geographic traceability of the trade. Using a target sequencing (gene capture) approach of 671 loci, we identified distinct population units for each species and their underlying biogeographic drivers, variable levels of diversity with certain units requiring attention, potentially novel taxa, and warn of a globalized trade in major Asian cities. These clusters provide the first step to informed population management and a reference for geographic traceability once additional samples from seizures are obtained.This work will provide significant resources to aid conservation researchers and practitioners in building on our knowledge of pangolins in priority areas and managing populations for all eight species. This work also forms the basis for a forensic DNA registry and for identifying the best suit of loci and SNPs for accurately separating populations, which in turn may be incorporated into versatile DNA-based ‘toolkits’ used for tracing the illicit pangolin trade in the future.Les pangolins (Pholidota) sont un groupe de mammifères myrmécophages composé de huit espèces existantes, quatre en Asie et quatre en Afrique. Ils sont considérés comme les mammifères les plus trafiqués au monde, une étiquette qui, avec celle d'un hôte intermédiaire COVID-19 non fondé, a placé les pangolins sous les projecteurs du public et de la conservation. Malgré cela, les connaissances sur les pangolins sont limitées et il n'y a pas encore de ressources et d'outils en place pour guider une action de conservation efficace. Fournir ces ressources pour orienter les investissements dans les domaines de recherche prioritaires, délimiter les unités de conservation pour la gestion, ainsi que pour identifier les régions et les itinéraires sources du trafic est essentiel pour réduire la dépendance excessive à la réglementation internationale qui a eu un effet limité sur le commerce du pangolin. Notre objectif est donc de fournir un aperçu des connaissances sur les pangolins et de générer des ressources pour orienter les recherches futures sur la conservation grâce à un examen systématique, ainsi que de développer les bases d'une gestion efficace des populations et de retracer le commerce des pangolins à l'aide de techniques moléculaires.Dans le premier chapitre, nous avons cherché à examiner systématiquement les lacunes et la dynamique de la recherche sur les pangolins, les principaux moteurs de l'intérêt public pour eux, et leur exploitation commerciale à travers des produits brevetés. Ces trois lignes d'investigation ont ensuite été combinées pour proposer des lignes directrices holistiques de recherche et d'action de conservation pour une meilleure conservation des pangolins à un moment où le monde s'est tourné vers eux. Le deuxième chapitre tournait autour de la compréhension du cadre évolutif mondial chez les Pholidota et de ses implications pour la conservation, en générant et en analysant des génomes entiers de toutes les espèces existantes. Nous avons évalué la phylogénie du pangolin, les estimations de divergence et le flux de gènes anciens, ainsi que l'histoire démographique par espèce et la diversité à l'échelle du génome. Nous avons clarifié l'existence d'une espèce de pangolin asiatique potentiellement nouvelle, fourni des ressources génomiques pour les espèces existantes de Pholidota et une liste de gènes orthologues classés par diversité pour faciliter les efforts de conservation génétique et médico-légale. Le troisième chapitre s'est concentré sur l'identification des populations intra-espèces et des mélanges potentiels dans l'aire de répartition géographique de chaque espèce de pangolin afin d'augmenter les ressources pour la génétique de conservation et la traçabilité géographique du commerce. En utilisant une approche de séquençage cible (capture de gènes) de 671 loci, nous avons identifié des unités de population distinctes pour chaque espèce et leurs moteurs biogéographiques sous-jacents, des niveaux de diversité variables avec certaines unités nécessitant une attention, des taxons potentiellement nouveaux et avertissons d'un commerce mondialisé des principaux espèces asiatiques. villes. Ces grappes constituent la première étape vers une gestion informée de la population et une référence pour la traçabilité géographique une fois que des échantillons supplémentaires provenant des saisies sont obtenus.Ce travail fournira des ressources importantes pour aider les chercheurs et les praticiens de la conservation à tirer parti de nos connaissances sur les pangolins dans les zones prioritaires et à gérer les populations des huit espèces. Ce travail constitue également la base d'un registre d'ADN médico-légal et de l'identification de la meilleure combinaison de loci et de SNP pour séparer avec précision les populations, qui à leur tour peuvent être incorporés dans des «boîtes à outils» polyvalentes basées sur l'ADN utilisées pour retracer le commerce illicite de pangolins à l'avenir
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.
