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

Excursions (hypo- et hyperglycémiques) et variabilité glycémique en réponse à différents types d’exercices aigus chez des personnes qui n’ont pas de diabète ou vivant avec le diabète de type 1
No full textLe diabète de type 1 (DT1) se caractérise par la destruction auto-immune des cellules ß des îlots de Langerhans du pancréas productrices d’insuline, entraînant un état d’hyperglycémie chronique. Malgré une prise en charge très fine de la maladie, s’appuyant sur l’insulinothérapie fonctionnelle, les personnes vivant avec le DT1 sont fréquemment sujettes à des épisodes hypoglycémiques et hyperglycémiques en raison de difficultés à adapter le traitement insulinique, notamment lors de l’activité physique. L’activité physique procure de nombreux bénéfices pour la santé que l’on ait ou non un diabète. Cependant, dans le cadre du DT1, les excursions glycémiques lors de l’activité physique peuvent conduire à des barrières à l’activité physique dans cette population ou peuvent limiter les performances sportives d’athlètes vivant avec le DT1.
L’objectif de cette thèse était triple : 1) Étudier les barrières à l’activité physique chez les enfants et adultes vivant avec le DT1 et à leurs liens avec les excursions glycémiques réellement vécues dans la vie quotidienne et d’autant plus autour de l’activité physique, 2) Chez des enfants vivant avec le DT1, comparer deux types d’exercice (exercice aérobie continu vs. intermittent intense), représentatifs de leur activité physique spontanée, et explorer leurs effets sur les variations glycémiques à l’exercice et à la récupération précoce et tardive et, 3) Mesurer la glycémie en continu, à l’exercice et à la récupération, chez des sportifs en endurance qui n’ont pas de diabète, afin de comprendre les mécanismes impliqués dans la régulation de la glycémie lors d’épreuves d’ultra-endurance et de transposer ces résultats chez des sportifs vivant avec le DT1.
Les résultats montrent que : 1) Chez les enfants, plus le temps passé <54 mg.dL-1 les nuits suivant les séances d'activités physiques augmente, plus la peur de l'hypoglycémie est importante. Chez les adultes, étonnamment, ceux qui déclarent le moins l’hypoglycémie comme une barrière à l’activité physique sont ceux qui ont le plus grand pourcentage de séances d’activités physiques entraînant une baisse de glycémie; 2) Le risque hypoglycémique n’est pas supérieur lors d’un exercice continu modéré représentatif de l’activité physique spontanée des enfants et, cet exercice semble efficace pour diminuer l’hyperglycémie retrouvée les jours inactifs sur la même période de temps; 3) Un risque hyperglycémique existe lors des phases intenses de la course et pendant 48 heures de récupération lors d’un ultra-trail réalisé chez des athlètes qui n’ont pas de diabète. Ce risque hyperglycémique à la récupération pourrait être en lien avec les dommages musculaires.Type 1 diabetes (T1D) is characterized by the autoimmune destruction of the insulin-producing ß-cells of the islets of Langerhans in the pancreas, leading to a state of chronic hyperglycemia. Despite very sophisticated management of the disease, based on functional insulin therapy, people living with T1D are frequently subject to hypoglycemic and hyperglycemic episodes because of difficulties in adapting insulin treatment, particularly during physical activity. Physical activity has many health benefits, whether or not you have diabetes. However, in the context of T1D, glycemic excursions during physical activity may lead to barriers to physical activity in this population or may limit the sporting performance of athletes living with T1D.
The aim of this thesis was threefold: 1) Investigate the barriers to physical activity in children and adults living with T1D and their links with the glycemic excursions actually experienced in daily life and all the more so around physical activity, 2) In children living with T1D, compare two exercise modalities (continuous aerobic exercise vs. intense intermittent), representative of their spontaneous physical activity, and explore their effects on glycemic variations during exercise and early and late recovery and, 3) Measure glycemia continuously, during exercise and recovery, in endurance athletes without diabetes in order to understand the mechanisms involved in regulating glycaemia during ultra-endurance events and transpose these results to athletes living with T1D.
The results show that: 1) In children, the greater the time spent <54 mg.dL-1 on the nights following physical activity sessions, the greater the fear of hypoglycemia. Surprisingly, among adults, those who least reported hypoglycemia as a barrier to physical activity were those who had the highest percentage of physical activity sessions resulting in a drop in blood glucose levels; 2) The risk of hypoglycemia is no greater during continuous moderate exercise representative of the spontaneous physical activity of children, and this exercise appears to be effective in reducing the hyperglycemia found on inactive days over the same period of time; 3) A hyperglycemic risk exists during the intense phases of the race and during 48 hours of recovery during an ultra-trail run carried out in athletes who do not have diabetes. This hyperglycemic risk during recovery could be related to muscle damage
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.
