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
Utility of neuraminidase inhibitor dispensing data as a tool for influenza surveillance
No full textSurveillance performed using routinely collected electronic data offers advantages that include a short reporting delay and a low acquisition cost. Monitoring of neuraminidase inhibitor (NI) dispensing in community pharmacies has emerged as a possible automated information source for influenza surveillance. However, little is known about the utility of these data for monitoring influenza activity. Therefore, we aimed to evaluate the timeliness, correlation, and predictive accuracy of community pharmacy NI dispensing in relation to laboratory-confirmed influenza activity in Quebec, Canada, during 2010-2013. Our secondary objective was to compare the characteristics of NI dispensing to those of visits for influenza-like illness (ILI) in emergency departments (ED), a commonly used source of surveillance data.Provincial weekly counts of positive influenza laboratory tests were used as a reference measure for the level of influenza circulation. We applied ARIMA models to account for seasonality and computed cross-correlation functions to measure the strengths of association and lead-lag-relationships of NI dispensing and ILI ED visits to our reference indicator. Finally, using an ARIMA model, we evaluated the ability of NI dispensing and ILI ED visits to predict laboratory–confirmed influenza. NI dispensing was significantly correlated (R=0.68) with influenza activity with no lag; the earliest statistically significant correlation occurred with a lead-time of 1 week. The maximal correlation of ILI ED visits was not as strong (R=0.50), but occurred with a lead-time of 1 week. Both NI dispensing and ILI ED visits were significant predictors of laboratory-confirmed influenza in a multivariable model; the predictive potential was greatest when NI counts were lagged to precede laboratory surveillance by two weeks.We conclude that NI dispensing data can provide timely and valuable information for the surveillance of influenza at the provincial level.La surveillance qui s'appuie sur des données électroniques recueillies et enregistrées en routine offre des avantages tels qu'un court retard de déclaration ainsi qu'un faible coût d'acquisition. La surveillance des ventes au détail de médicaments sur prescription contre l'influenza, les l'inhibiteurs de la neuraminidase (NI), a émergé comme une source possible d'information automatisée pour la vigie sanitaire de la grippe. Toutefois, les caractéristiques de la performance de ces données comme objet de surveillance ne sont pas bien connues. Dès lors, nous avons cherché à évaluer les données de distribution des NI dans les pharmacies communautaires comme un nouvel outil de surveillance de l'influenza, de par leur relation d'ordre temporelle (décalage), de leur corrélation et de leur capacité prédictive, en comparaison à l'activité grippale confirmée en laboratoire, au Québec, Canada, de 2010 à 2013. Notre objectif secondaire était de comparer ces caractéristiques à celles de la surveillance des visites pour syndrome d'allure grippal (SAG) inscrites aux d'urgences.Les données hebdomadaires provinciaux du nombre de tests de laboratoire positifs pour l'influenza ont été utilisées comme mesure de référence pour le niveau d'activité grippale. Nous avons appliqué la méthodologie de modélisation ARIMA pour tenir compte de la saisonnalité et de l'autocorrélation. Nous avons ensuite calculé les fonctions de contre-corrélation pour mesurer les forces d'association et explorer les relations temporelles entre la distribution des NI et les visites SAG avec notre mesure de référence. Enfin, nous avons évalué la valeur prédictive de la distribution des NI et des visites SAG dans le montage d'un modèle ARIMA pour les comptes d'influenza confirmés en laboratoire.La distribution des NI était significativement corrélée (R = 0,68) avec l'activité grippale au temps de latence zéro; la première corrélation statistiquement significative a eu lieu avec un décalage anticipatoire d'une semaine. La corrélation maximale des visites SAG n'était pas aussi forte (R = 0,50), mais a culminé une semaine plus tôt que les distributions NI. Tant la distribution des NI et les visites SAG à l'urgence étaient des variables prédictives significatives dans un modèle multivarié de cas confirmés en laboratoire; le potentiel prédictif du modèle était maximal lorsque les distributions NI ont été décalées pour précéder la surveillance en laboratoire de deux semaines.Ainsi, nous concluons que les données de distribution NI peuvent fournir des informations utiles et en temps opportun pour la surveillance de la grippe à l'échelle provinciale
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

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.
