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
TUMORS PANORAMA IN TANGUIETA ZONE HOSPITAL OF SAINT JEAN DE DIEU IN BENIN
No full textBackground: Generally, tumors are a major health problem and cancers are the most feared. The absence of cancer registry in Benin
makes it difficult to assess the extent of the cancer on the population. Aim: To describe the epidemiology of tumors at Saint Jean de Dieu
Hospital of Tanguiéta. Materials and methods: A descriptive and retrospective study from january 1st 2014 to 31 december 2015 in
Zone Hospital of St. Jean of Dieu Tanguiéta were done. Were included patients admitted to tumor confirmed by an anatomo-pathological
examination. Data were collected from the Logihosp software and patients medical records. Results: In 2014, tumors accounted for 1.9%
of admissions (282 cases including 124 benign and malignant 158); in 2015 they accounted for 2.0% (290 cases including 110 benign
and 180 malignant). The average age of patients with benign tumor was 39.6 ± 12.4 years old, ranging from 7 days to 85 years old. For
malignant tumors, the mean age of patients was 40.7 ± 20.8 years, ranging 6 months and 95 years olsd. The most common cancers were
the liver (33 cases) and cervical (27 cases); the most frequent site of benign tumors was the uterus (159 cases). Intra-hospital mortality
was 0.9% for benign tumors and 8.3% for malignant tumors. Conclusion: The incidence of tumors is underestimated and cancers have
high mortality account held therapeutic limitations and multiple causes of delays
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

Amputations de membres dans un hopital de zone du Nord-Bènin: A' propos de 122 cas
No full textAbstract
Limb amputation at a zone hospital in Northern Benin area: about 122 cases
Aim: To study limb amputations at the Zone Hospital of Saint Jean de Dieu of Tanguiéta (ZHSJDT) in
Benin.
Materiel and methods: This was a descriptive study with retrospective data collection over a 5 yearperiod
from January 1th 2009 to December 31th 2013. Different registers have been consulted. Data
analysis was conducted by informatics and statistical significance was set at the .05 level.
Results: One hundred and twenty-two (122) amputations in 118 patients were carried out. The mean
age was 37.4 years, ranging from 1 to 80 years and 71.2% of the amputations occurred in manual
workers respect to other professional activities (p = 0.041). Seventy (70) amputations (57.4 %) were
performed on the left body side and 52 (42.6%) on the right side. Lower limbs were involved in 73.8%
of cases and upper extremities in 26.2%. Major amputations accounted for 86.1% and minor amputations for 13.9% (p = 0.002). The causes of amputations were road injuries in 41.0% of cases and
post-traumatic gangrene in 58.0%. Postoperative complications occurred in 37.7% of patients with
22.1% of surgical site infections and 10.2% of psychiatric manifestations. Mortality was 1.7%. Only
9.0% of cases had a prosthetic device after amputations.
Conclusion: The young and active population are the most affected by limb amputations in ZHSJDT.Résumé
Objectif : Etudier les amputations de membres à l’Hôpital de Zone Saint Jean de Dieu de Tanguiéta
(HZSJDT) au Bénin.
Matériel et méthodes : Il s’agissait d’une étude descriptive avec recueil rétrospectif des données sur
une période de 5 ans allant du 1er janvier 2009 au 31 décembre 2013. Différents registres ont été
consultés. Le traitement et l’analyse des données ont été informatiques. Les résultats ont été
considérés significatifs pour un seuil alpha de 5%.
Résultats : Au total, 122 amputations ont été réalisées chez 118 patients. L’âge moyen était de
37.4 ± 21.2 ans avec des extrêmes de 1 et 80 ans et un sex-ratio de 3.7. Les travailleurs manuels ont
représenté 71.2% des amputés (p = 0.041). Soixante-dix amputations (57.4%) ont été réalisées du
côté gauche et 52 (42.6%) du côté droit. Le membre pelvien était concerné dans 73.8% et le membre
thoracique dans 26.2%. Les amputations majeures ont représenté 86.1%, les mineures 13.9% avec
p = 0.002. Les traumatismes ont constitué 41% des causes avec 58% de gangrènes post-traumatiques.
Des complications post-opératoires sont survenues dans 37.7% avec 22.1% d’infection du site opératoire
et 10.2% de manifestations psychiatriques. La mortalité a été de 1.7%. Le taux d’appareillages a
été de 9%.
Conclusion : La population jeune et active est la plus concernée par les amputations de membre à
