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
Les effets à long terme de la rééducation périnéale du post-partum : évaluation en fonction de l’incontinence urinaire et des prolapsus
No full textAim: The aim of this study was to measure the current impact of the postpartum perineum physiotherapy, between 1982 and 1996, on urinary incontinence and prolapses.Tools and methods: The studied population was recruited through the Postnatal Care Service of the Pitié-Salpêtrière Hospital as well as through friends and acquaintances. 92 women met the criteria and answered anonymously to the MHU, Contilife, PDFI-20 and PFIQ-7 questionnaires. Results: If women who underwent physiotherapy had better scores, with 3 to 30% improvement, there were no statistical differences (p-values between 0.063 and 0.733). We observed an association between urinary incontinence and the type of physiotherapy session done (Fischer test: p =0.004), without an association between the current state of urinary incontinence and the number of sessions done (Fischer test: p =0.798).Conclusion: The retrospective study on this population did not show any long term benefits on the occurrence of urinary incontinence and prolapses. However, certain types of physiotherapy could be more effective than others. There where inherent limits to the methods used. It could be interesting to continue this study on a larger scale and to measure the impacts on the prevention of dyspareunia and anal incontinence.Objectifs : L’étude évaluait l’impact actuel de la rééducation périnéale du post-partum effectuée entre 1982 et 1996 en France par l’appréciation des bénéfices attendus sur l’incontinence urinaire et les prolapsus.Matériel et méthodes : La population de l’étude était recrutée en suites de couche à la Pitié-Salpêtrière et parmi des connaissances. Entraient dans les critères de l’étude 92 femmes. L’étude anonyme était constituée de différents questionnaires (MHU, Contilife, PDFI-20 et PFIQ-7) afin de comparer les femmes ayant effectué ou non une rééducation.Résultats : En moyenne, avoir suivi une rééducation améliorait les scores entre 3% et 30%, la différence de score n’étant pas statistiquement significative avec un p allant de 0,063 à 0,733. Il existait un lien statistique (test de Fischer : p=0,004) entre le type de rééducation et l’état de continence urinaire présent. Il n’y avait pas de lien statistique (test de Fischer : p=0,798) entre le nombre de séances de rééducation effectuées et l’état de continence urinaire présent.Conclusion : L’étude rétrospective de cette population ne montrait pas de bénéfices à long terme sur l’incontinence urinaire et les prolapsus. Certains types de rééducations pourraient être plus efficaces que d’autres. La méthodologie de l’étude comportait des limites intrinsèques. Poursuivre l’étude avec une plus grande population et en analysant les impacts de la rééducation sur les dyspareunies et l’incontinence anale serait intéressant
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
Impact de la chirurgie bariatrique sur la grossesse : étude rétrospective chez les patientes présentant une obésité morbide
No full textObjective : France counts today 14.8 millions of people overweight and 6.9 millions people obese. Obesity poses a significant risk to reproductive-aged women. Bariatric surgery is more and more suggested to help patients in morbid obesity lose significant weight. The main goal of the study is to analyse the impact of bariatric surgery on morbid obesity patients studying maternal , obstetrical and neonatal outcomes on those patients.Methods : A retrospective study was made of 38 post-bariatric surgery pregnancies with an IMC > 40 kg/m2 in pre-surgery compared to 81 mobid obesity pregnancies which IMC > 40 kg/m2 non operated. Weight gain pregnancies, pregnancy complications, deliveries, neonatal outcomes and the impact of time between surgery and delivery were analysed.Results and conclusion : The post-bariatric surgery patients gained more significant weight than non-operated patients (p=0.01). However they developed less gestational diabetes (p=0.005). There were less cervical maturation (p=0.002) but more induction of labour (p=0.005) in the post-surgery group of patients and there were less emergency cesarians as well (p=0.01). The neonatal outcomes were similiar in both groups. As far as the pregnancy course and the delivery itself were concerned there were no significant difference according to the delay (>18 months) between surgery and the beginning of the pregnancy. Finally, the post-bariatric surgery patients (Gastric banding and Sleeve gastrectomy) gave birth to more macrosomia newborns (p=0.001). Bariatric surgery improves obstetric and neonatal and maternal prognosis..There is no significant impact concerning the neonatal prognosis in this study. A multidisciplinary follow-up is compulsory in order to avoid nutritional deficiencies or important weight gain during pregnancy.Objectifs : La France recense aujourd’hui 14,8 millions de personnes en surpoids et 6,9 millions de personnes obèses. L’obésité présente un risque important pour les femmes en âge de procréer. La chirurgie bariatrique est une méthode de plus en plus proposée pour permettre une perte de poids importante chez des patientes en obésité morbide. L’objectif principal de l’étude est d’analyser l’impact la chirurgie bariatrique sur des patientes en obésité morbide en étudiant le pronostic maternel, obstétrical et néonatal de ces patientes.Matériel et méthodes : Une étude rétrospective a été menée sur 38 grossesses issues de patientes opérées d’une chirurgie bariatrique avec IMC ≥ 40 kg/m2 en pré-chirurgie comparer à 81 grossesses issues de patientes en obésité morbide (IMC ≥ 40 kg/m2 en pré-conceptionnel) non opérées. La prise de poids pendant la grossesse, les complications de la grossesse, les modalités de l’accouchement, les issues néonatales et l’influence du délai entre la chirurgie et la grossesse ont été analysés.Résultats : Les patientes opérées d’une chirurgie bariatrique prenaient significativement plus de poids que les patientes non opérées (p=0,01). Cependant, les patientes opérées développaient moins de diabète gestationnel (p=0,005). Il y avait moins de maturation cervicale (p=0,002) mais plus de déclenchement du travail (p=0,005) dans le groupe de patientes opérées. De même, il y avait moins de césarienne en urgence (p=0,01). Les issues néonatales étaient comparables dans les 2 groupes. Il n’y avait pas de différence significative dans les 2 groupes concernant le déroulement de la grossesse et de l’accouchement en fonction du délai (>18 mois) entre la chirurgie et le début de grossesse. Enfin, les patientes opérées d’une chirurgie bariatrique à méthode restrictive (AGA et sleeve gastrectomy) donnaient naissance à plus de nouveau-nés macrosomes (p=0,001). La chirurgie bariatrique améliore le pronostic maternel et obstétrical. Il n’y a pas d’impact concernant le pronostic néonatal dans ce travail. Une prise en charge pluridisciplinaire et une surveillance étroite de ces patientes opérées est indispensable afin d’éviter des carences nutritionnelles ou une prise de poids gestationnelle importante
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
