Full text linkEl siguiente proyecto de investigación se propone evaluar la incidencia de
la hemiparálisis diafragmática comparando 2 técnicas anéstesicas entre el
bloqueo braquial por vía costoclavicular y bloqueo braquial supraclavicular
ecoguiados en pacientes sometidos a cirugía de miembro superior en el
Hospital Belén de Trujillo durante el periodo comprendido entre diciembre
2020 a marzo 2021. Se realiza un estudio tipo ensayo clínico aleatorizado
controlado. Se realizará en todos los pacientes programados para cirugía
electiva de miembro superior, de todos se tomarán en cuenta los que
cuenten con los criterios de selección; luego se le realizará un muestreo
aleatorio simple a cada uno de los grupos en estudio en un número de 23
pacientes por grupo. Se diseñó formatos para recolección de datos dentro
de los mismos se recolectará variables de interés para el estudio;
previamente todos los pacientes deben dar su consentimiento para su
participación en el estudio. Los datos serán procesados en software
estadístico SPSS V26.0. Se utilizarán pruebas t student para comparar
datos continuos distribuidos normalmente y pruebas de Mann-Whitney para
datos no distribuidos normalmente. Para las variables categóricas, se
utilizará la prueba de Chi-cuadrado de Pearson ambas con un nivel de
significancia del 5% (p < 0,05.). Esta investigación será revisada para su

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Emergence and dissemination of multi-resistant gram-negative Enterobacteriaceae : lessons to be learnt from local and national surveillance programs in Belgium
No full textA local longitudinal surveillance programme, that was initially designed for local monitoring of ESBL-producing Enterobacteriaceae in a tertiary care hospital, previously highlighted the emergence and spread of novel extended-spectrum ß-lactamases (CTX-M). This was pointed out regarding community-associated Enterobacteriaceae, particularly Escherichia coli, several years before their recognition and confirmation at the national level. The emergence was characterised by the rapid spread of a major E. coli multi-drug resistant (MDR) and pathogenic CTX-15 (ST131) pandemic clone (found in extra-intestinal virulent strains) in Belgium. The findings of the local and national surveillance programs supports the progressive increase in Belgium of MDR-related infections, including urinary tract infections, with limited therapeutic options and requiring the use of parenteral antibiotics only available in hospitals.To quantify the seriousness of the problem, a ‘global coordinated network’ for antimicrobial surveillance resistance must be urgently developed. This network should include a longitudinal analysis of resistance in different ecosystems (human, animal, water and food) that not yet existing in our country. A global coordinated network is key for the implementation and evaluation of effective measures to control the current situation and address new challenges, such as the recent emergence of carbapenemase-producing Enterobacteriaceae.Dans un hôpital de soins tertiaires belge, un programme local de surveillance des entérobactéries productrices de ß-lactamases à spectre étendu a mis en évidence l'émergence et la propagation de nouvelles enzymes (CTX-M), et cela plusieurs années avant leur reconnaissance au niveau national. Cette émergence a été caractérisée notamment par la propagation rapide d’un clone pathogène CTX-M-15 (ST131) d’Escherichia coli d’origine communautaire. Tant les données des programmes locaux que nationaux indiquent l'augmentation progressive en Belgique d’infections associées à ces germes multirésistants, avec des options thérapeutiques très limitées et nécessitant l'utilisation d'antibiotiques seulement disponibles en milieu hospitalier. Déterminer l’ampleur du problème nécessite un réseau global de surveillance pour la résistance aux antimicrobiens, comprenant une analyse longitudinale et coordonnée de la résistance dans différents écosystèmes (humain, animaux), de l'eau et des produits alimentaires. Un tel réseau est encore inexistant dans notre pays.(MED - Sciences médicales) -- UCL, 201
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
