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
Aspects étiologiques, cliniques et thérapeutiques des positions compensatrices de tête
No full textBackground: In the ophthalmic world, the ocular head tilt allows research on visual improvement which can be: monocular: increase of visual acuity; binocular: improvement of binocular vision and stereoscopy; motor: by searching an area where deviation will decrease in paralysis or an area of less nystagmus. Improvement of vision earns on discomfort of torticollis. This position is adopted by the patient so as to compensate for an oculomotor or sensorial disorder. It is therefore different in terms of disorder associated with it (horizontal, vertical,oblique or torsional).Objectives, population and methods: The aim of this research paper was to achieve a statistical retrospective study on etiological, clinical and therapeutic aspects of ocular headtilt among 60 patients at Gabriel-Montpied hospital. We have collected information from the orthoptic and ophthalmologic examinations performed in the hospital. First, we have studied the frequency of the different diseases within the population but also the different types of ocular head tilts found (head turn on the right or on the left, tilted head in right or left shoulder), the frequency of treatment used (prism, botulism toxin injections and surgery) as well as their impact on head tilts.Results: The results showed that the etiology mainly found was nystagmus (47%) followed by early squint (20%) and paralysis (15%). With regards to the different types of head tilt, we found 47% of horizontal head tilts,against 23% of oblique head tilt. We found 15% of vertical head tilt as well as 15% of mixinghead tilts, with a horizontal and vertical component. Moreover, among the 60 patients of the study, 53% received treatment (prism, botox, surgery), 84% of patients were prescribed prisms, 28% had surgery or 13% received botox injection. Several conclusions can be drawn from those results. Prisms improve more often ocularhead tilt. Patients with nystagmus are mostly those who wore prisms (88%). In 40% of the cases, prisms were prescribed when patients have a horizontal ocular head tilt (turn right or left). The main indication for surgery was nystagmus (45%) and in the majority of cases, surgery was indicated to patients with a horizontal or oblique head tilt (33.5%).Discussion and conclusion: It is a priority to pay particular attention to ocular head tilt during orthoptic and ophtalmologic examination, because this will allow us to know the causes of ocular torticollis and why the patient have them. With a precise examination we can bring a complete care for the patient.Introduction : Dans le monde ophtalmologique, les positions compensatrices de tête permettent la recherche d’une amélioration visuelle qui peut être : monoculaire : une augmentation de l’acuité visuelle ; binoculaire : avec une amélioration de la vision binoculaire et de la stéréoscopie ; motrice : en recherchant une zone où la déviation va diminuer dans une paralysie ou une zone de moindre battement du nystagmus. L’amélioration de la vision prime sur la gêne du torticolis. Cette position va être adoptée par le patient afin de compenser un trouble moteur ou sensoriel, elle sera donc différente en fonction du trouble qui lui est associé (horizontale,verticale, oblique ou torsionnelle).Objectifs, population et méthode : Le but de ce mémoire est de réaliser une étude statistique rétrospective sur les aspects étiologiques, cliniques et thérapeutiques des positions compensatrices de tête parmi 60 patients du CHU Gabriel Montpied. Nous avons collecté les données à partir de l’examen orthoptique puis ophtalmologique réalisé au CHU. Dans un premier temps nous avons étudié la fréquence des différentes étiologies au sein de la population mais aussi les différents types de position compensatrice de tête retrouvés (tête tournée à droite ou à gauche, tête penchée sur l’épaule droite ou gauche), la fréquence des traitements utilisés (prismes, injection de toxine botulique, chirurgie) ainsi que leur impact sur la position compensatrice de tête.Résultats : Les résultats montrent donc que l’étiologie principalement retrouvée est le nystagmus (47%) suivi du strabisme précoce (20%) et des paralysies (15%). En ce qui concerne les différents types de position compensatrice de tête, nous retrouvons le plus souvent des positions compensatrices de tête horizontales (47%) contre 23% de positions compensatrices obliques. On retrouve 15% de positions compensatrices verticales ainsi que 15% de positions mixtes c'est-à-dire avec une composante horizontale et verticale. De plus sur les 60 patients de l’étude, 53% ont reçu un traitement (prisme, botox, chirurgie),84% des patients ont eu des prismes de prescrits, 28% une chirurgie et 13% une injection de toxine. À partir de ces résultats on peut tirer plusieurs conclusions. Les prismes améliorent le plus souvent la position compensatrice de tête quand ils sont prescrits, les patients avec des nystagmus sont ceux qui sont le plus souvent prismés (88%) et dans la majorité des cas, les prismes sont prescrits lorsque le patient a une position compensatrice de tête horizontale (tête tournée à droite ou à gauche) (48%). Pour la chirurgie, l’indication principale a également été les nystagmus (45%) et dans la majorité des cas, la chirurgie à été indiquée pour les patients avec une position compensatrice de tête horizontale ou oblique (33.5%).Discussion et conclusion : Il est primordial d’apporter une attention particulière aux positions compensatrices de tête lors de l’examen orthoptique et ophtalmologique car cela va nous permettre de connaître la cause du torticolis et pourquoi le patient l’utilise. C’est grâce à un examen précis qu’on pourra apporter une prise en charge complète au patient
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
