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
Veterinary electroencephalography (EEG) in dogs and cats : feasibility, development of prοtοcοles for performing and interpreting tracings
No full textL’objectif de ce travail était d’évaluer la faisabilité de l’EEG chez des chiens et des chats sans sédation, de proposer les premiers abaques pour l’interprétation et de proposer des recommandations pour la pratique de l’EEG de routine en clinique vétérinaire. Une étude préalable sur 6 chiens et 6 chats sains a permis d’obtenir des tracés physiologiques de référence en état de veille, de somnolence, de sommeil et de sommeil paradoxal. Cent cinquante enregistrements EEG avec capteurs de polygraphie ont ensuite été réalisés sur 140 animaux combinés à des protocoles de sensibilisation. L’évaluation de la qualité et de l’interprétabilité des tracés a été faite en comparant les résultats obtenus avec 2 types d’électrodes et leur système de maintien spécifique. Les enregistrements vidéo-EEG ont été réalisés avec succès sans sédation, sauf pour 9 animaux, sur des chiens et de chats de tout gabarit, âge, sexe. La durée médiane des enregistrements EEG était de 40 minutes. Soixante-quinze pour cent des EEG de chiens et 83 % des EEG de chats étaient lisibles pendant plus de 50 % et jusqu’à 100 % de leur durée. La discrimination des états de vigilance à partir de l'analyse des rythmes (éveil, somnolence, sommeil) a été possible dans 99 % des EEG de chiens et 91 % des EEG de chats. Des réponses à la stimulation photique ont été observées dans 11 % des EEG de chiens et 85 % des EEG de chats. L’intérêt médical des enregistrements EEG a été directement informatifs dans 34% des examens : dans 26% des cas, les anomalies EEG étaient associées à des signes cliniques, et dans 8 % des cas, il s'agissait d'anomalies EEG sans symptômes cliniques pendant l'enregistrement. Certaines anomalies ont pu être provoquées.Nous avons donc mis au point une procédure standardisée de vidéo-EEG sans anesthésie, non invasive chez les chiens et les chats. Les critères techniques et médicaux qualitatifs et quantitatifs ont été évalués et étaient conformes aux recommandations de l'EEG humain. De plus, nous avons démontré sa pertinence et sa précision à des fins diagnostiques, apportant des arguments supplémentaires en faveur de l'utilisation de l'EEG comme test d'exploration fonctionnelle neurologique de première intention.The aim of this work was to assess the feasibility of EEG in dogs and cats without sedation, to propose the first abacuses for interpretation and to offer recommendations for routine EEG practice in veterinary clinics. A preliminary study on 6 healthy dogs and 6 healthy cats provided physiological reference tracings during wakefulness, drowsiness, sleep and REM sleep. One hundred and fifty EEG recordings with polygraph sensors were then made on 140 animals, combined with sensitization protocols. The quality and interpretability of the EEG were assessed by comparing the results obtained with 2 types of electrodes and their specific holding system. Video-EEG recordings were successfully performed without sedation, except for 9 animals, on dogs and cats of all sizes, ages and sexes. The median duration of EEG recordings was 40 minutes. Seventy-five percent of dog EEGs and 83% of cat EEGs were readable for more than 50% and up to 100% of their duration. Discrimination of states of alertness from rhythm analysis (wakefulness, somnolence, sleep) was possible in 99% of dog EEGs and 91% of cat EEGs. Responses to photic stimulation were observed in 11% of dog EEGs and 85% of cat EEGs. The medical relevance of EEG recordings was directly informative in 34% of examinations: in 26% of cases, EEG abnormalities were associated with clinical signs, , and in 8% of cases, they were EEG abnormalities without clinical symptoms during recording. Some events may have been provoked.We developed a standardized procedure for anesthesia-free, non-invasive video-EEG in dogs and cats. Qualitative and quantitative technical and medical criteria were evaluated and were in line with human EEG recommendations. In addition, we demonstrated its relevance and accuracy for diagnostic purposes, providing further support for the use of EEG as a first-line neurological functional exploration test

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.
