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
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
Impact of comorbidities on chronic disease outcomes
No full textLes comorbidités sont des pathologies associées aux maladies chroniques, qui en influencent la morbi-mortalité et la qualité de vie des patients. La forte prévalence des comorbidités et leur impact pronostique justifient une prise en charge multidisciplinaire intégrée. L’objectif de notre travail était d’étudier l'impact des comorbidités sur le pronostic de la maladie chronique. Pour cela, nous avons choisi deux modèles de maladies inflammatoires chroniques : la polyarthrite rhumatoïde (PR) et les vascularites à ANCA (VAA), où nous avons choisi de focaliser sur le risque cardiovasculaire, et deux modèles de pathologies non-inflammatoires chroniques : l’insuffisance cardiaque, où nous avons choisi la mortalité comme variable d’intérêt, et l’arthrose, où nous avons étudié la progression radiographique. Résultats : Dans les VAA, nous avons mis en évidence par une revue systématique de la littérature, une augmentation des maladies cardiovasculaires (MCV), en particulier à la phase aigüe de la maladie. Ensuite, dans une cohorte de 103 patients atteints de VAA, nous avons montré que la survenue d’évènements cardiovasculaires majeurs (MACEs) était significativement associée à l’âge élevé, aux antécédents cardiovasculaires, à la sédentarité, à l’hypertension artérielle, et à la dyslipidémie. La survenue de MACEs était aussi associée au nombre de facteurs de risque cardiovasculaire. Nous avons ensuite étudié l’impact à 10 ans d’une faible corticothérapie dans une cohorte de 608 patients atteints de PR précoce (cohorte ESPOIR). Le critère d’évaluation était composite associant décès, MCV, infections graves et fractures. L'exposition cumulée la plus élevée aux corticoïdes était associée au risque le plus élevé de survenue du critère composite, de MCV et d'infections graves. Le risque associé au traitement par corticoïdes a augmenté au fil du temps entre la première visite de suivi et 10 ans. Dans le domaine de l’insuffisance cardiaque, nous avons analysé les facteurs prédictifs de mortalité après une hospitalisation dans notre service de médecine interne pour insuffisance cardiaque aigue. La population étudiée était majoritairement féminine, d’âge moyen 82.9 ± 10.3 ans, avec une FEVG conservée et de nombreuses comorbidités. Sur 164 patients, 66.4% sont décédés avec un délai médian de 14 mois. En analyse univariée, les patients qui sont décédés au cours du suivi étaient significativement plus âgés, avaient un IMC plus faible et un indice de comorbidité de Charlson plus élevé. Ces patients avaient une fonction rénale plus altérée, et des niveaux plus élevés de NT-proBNP. En analyse multivariée, ajustée sur l’âge et la fonction rénale, les facteurs de risque de décès retrouvés étaient le poids d’entrée et de sortie, l’IMC, l’hypoalbuminémie, le taux de NT-proBNP et une durée d’hospitalisation plus longue. Enfin, en analysant les données à 5 ans de 384 participants non obèses de la cohorte KHOALA souffrant d’arthrose symptomatique de la hanche et/ou du genou, nous avons montré que les maladies cardiovasculaires étaient significativement associées à la progression radiographique dans l'arthrose du genou et de la hanche. Conclusion : Notre travail suggère des axes d’amélioration de la prise en charge globale des comorbidités ayant un impact pronostique pour les patients. Nos résultats plaident en faveur du dépistage et de la prise en charge adaptée des facteurs de risque cardiovasculaire modifiables pour réduire le risque cardiovasculaire des patients atteints de VAA, et ont montré l’impact notamment cardiovasculaire dose et temps-dépendant du traitement par corticoïdes à faible dose dans la PR. Nos résultats plaident également en faveur d’une prise en charge nutritionnelle optimisée des patients hospitalisés en médecine interne pour insuffisance cardiaque aigue, et enfin encouragent une gestion intégrée des maladies cardiovasculaires chez les patients non obèses souffrant d'arthrose du genou et de la hanche.Comorbidities are pathologies associated with chronic diseases, which influence morbidity and quality of life of patients. The high prevalence of comorbidities and their prognostic impact justify an integrated multidisciplinary management. The objective of our work was to study the impact of comorbidities on the prognosis of chronic disease. For this purpose, we chose two models of chronic inflammatory diseases: rheumatoid arthritis (RA) and ANCA vasculitis (AAV), where we chose to focus on cardiovascular risk, and two models of chronic non-inflammatory pathologies: heart failure, where we chose mortality as the variable of interest, and osteoarthritis (OA), where we studied radiographic progression. Results: In VAA, we highlighted by a systematic review of the literature, an increase in cardiovascular diseases (CVD), particularly in the acute phase of the disease. Then, in a cohort of 103 patients with VAA, we showed that the occurrence of major cardiovascular events (MACEs) was significantly associated with higher age, cardiovascular history, sedentary lifestyle, hypertension, and dyslipidemia. The occurrence of MACEs was also associated with the number of cardiovascular risk factors. We then studied the 10-year impact of low-level glucocorticoid (GC) therapy in a cohort of 608 patients with early RA (ESPOIR cohort). The endpoint was a composite of death, CVD, serious infections and fractures. The highest cumulative exposure to GC was associated with the highest risk of the composite endpoint, CVD and serious infections. The risk associated with GC treatment increased over time from the first follow-up visit to 10 years. In heart failure, we analysed the predictors of mortality after hospitalization in our internal medicine department for acute heart failure. The study population was predominantly female, elderly (mean age of 82.9 ± 10.3 years), with preserved LVEF, and with numerous comorbidities. Of 164 patients, 66.4% died with a median delay of 14 months. In univariate analysis, patients who died during follow-up were significantly older, had a lower BMI, and a higher Charlson Comorbidity Index. These patients had more impaired renal function, and higher NT-proBNP levels. In multivariate analysis, adjusted for age and renal function, the risk factors for death were weight, BMI, hypoalbuminemia, NT-proBNP level, and longer hospital stay. Finally, by analyzing the 5-year data of 384 non-obese participants from the KHOALA cohort with symptomatic hip and/or knee OA, we showed that CVD were significantly associated with radiographic progression in knee and hip OA. Conclusion: Our work suggests ways to improve the global management of comorbidities that have a prognostic impact on patients. Our results argue for the screening and management of modifiable cardiovascular risk factors to reduce the cardiovascular risk of patients with AAV, and have shown the dose- and time-dependent cardiovascular impact of low-dose GC treatment in RA. Our results also argue for an optimized nutritional management of patients hospitalized in internal medicine for acute heart failure, and finally encourage an integrated management of CVD in non-obese patients with knee and hip osteoarthritis

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.
