    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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” 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 link
    We 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

    Full text link
    We 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

    El propósito de este estudio es realizar un análisis multivariado para evaluar factores que contribuyen al desarrollo de Pseudoartrosis de fracturas diafisiaria de fémur, en los pacientes atendidos en el Hospital Universitario de Santander. Métodos: Se realizó un estudio observacional de cohorte prospectivo de alta calidad, de los pacientes que ingresaron con fractura diafisiaria de fémur, se realizó seguimiento a 9 meses buscando la incidencia de pseudoartrosis. Se ingresaron 53 fracturas diafisiaria de fémur durante el año 2015, 1 paciente falleció, 3 pacientes fueron remitidos a otras instituciones y un paciente requirió amputación por trauma vascular asociado, en total se le realizó seguimiento a 48 pacientes. Estudio de evidencia Nivel I para la pregunta de la investigación. Resultados: Realizamos un análisis multivariado aplicando regresión logística en busca de OR de las variables estudiadas a los sujetos que desarrollaron pseudoartrosis. Tenemos 10 pacientes (18%) con retardo de la consolidación de los cuales 5 (9%) terminaron en pseudoartrosis: 3 mujeres y 2 hombres, el tipo de trazo más asociado fue 32-A transverso y diafisiaria proximal, se encontró asociación positiva en ser mujer y presentar una fractura 32B-C (OR 15, p: 0.09) así como presentar una fractura 32 B-C en un trauma diferente a los asociados al tránsito (OR: 26, p: 0.03). Conclusiones: En nuestra serie se encontraron variables con mayor asociación a pseudoartrosis entre las que destacan ser mujeres, proceder de área rural y el antecedente tabaquismo. Contrario a nuestra hipótesis la fractura 32 A fue la más asociada a pseudoartrosis. Se requiere de una muestra mayor para dar validez a nuestro modelo de análisis y poder dar recomendaciones con peso estadístico, cada paciente debe ser estudiado de forma individual, recomendamos tener en cuenta los factores demográficos, de la lesión y del manejo que pueden llevarnos a un mal resultado. _EspecializaciónEspecialista en Ortopedia y TraumatologíaThe purpose of this study is to perform a multivariate analysis to evaluate factors that contribute to the development of femoral diaphyseal nonunion in patients treated at the Hospital Universitario de Santander. Methods: A prospective observational cohort study of patients who entered with femoral diaphyseal fracture was performed, followed up at 9 months seeking the incidence of nonunion. 53 femoral diaphyseal fractures were admitted during the year 2015, 1 patient died, 3 patients were referred to other institutions and one patient required amputation for associated vascular trauma. A total of 48 patients were followed up. Evidence study Level I for the research question. Results: We performed a multivariate analysis applying logistic regression in search of OR of the studied variables to the subjects who developed nonunion. We had 10 patients (18%) with delayed consolidation, of which 5 (9%) ended in nonuion: 3 women and 2 men, the most associated stroke type was 32-A transverse and proximal diaphyseal, positive association was found in Being female and presenting a 32B-C fracture (OR 15, p: 0.09) as well as presenting a 32 BC fracture in a trauma other than those associated with traffic (OR: 26, p: 0.03). Conclusions: In our series we found variables with a greater association to nonunion among those that stand out to be women, proceeding from rural area and smoking history. Contrary to our hypothesis, the 32 A fracture was the most associated with nonunion. It requires a larger sample to validate our analysis model and to be able to give recommendations with statistical weight, each patient should be studied individually, we recommend taking into account the demographic, injury and management factors that can lead us to a Bad result. _

    Nuestro trabajo nace a partir de la idea de diseñar una estructura organizacional y administrativa que permita establecer los principales procedimientos organizacionales, administrativos y estructurales a tener en cuenta para la dirección de un Centro de Alto Rendimiento Deportivo (CARD) que optimice el rendimiento de los deportistas de competencia, aficionado o profesional. En el presente trabajo se muestra inicialmente el desarrollo histórico del deporte y los principales modelos de CARD existentes en nuestro país y en los países con mayor nivel competitivo. Así mismo se revisan los conceptos generales de deporte de alto rendimiento como son sus funciones, sus objetivos y sus fases; la situación actual del deporte y el deportista en Colombia enfatizando en el conocimiento general de los programas establecidos por los organismos departamentales como son el Inderbú e Indersantander; y los fundamentos administrativos más relevantes para nuestro proyecto como son las teorías administrativas y el proceso de planeación. De esta manera se establece la organización y administración para el buen funcionamiento de un CARD en el municipio, mostrando las directrices (misión, visión, valores y objetivos), los servicios que presta a la comunidad deportiva, y su estructura organizacional, especificando en su organización (organigrama), procesos administrativos (gerenciales, misionales y de apoyo), funcionamiento (manual de procesos, manual de funciones) infraestructura, sistema de información , indicadores de gestión y sus costos (en inversión y en funcionamiento). Buscamos que esta propuesta de diseño administrativo y organizacional del CARD permita instaurar posteriormente un centro de servicios de salud especializados que se encuentre al servicio de los deportistas profesionales y aficionados que busquen mejorar su salud y desempeño competitivoEspecializaciónEspecialista en Administración de Servicios de SaludOur work is born starting from the idea of designing an organizational and administrative structure that allows to establish the main organizational, administrative and structural procedures to keep in mind for the address of a Center of High Sport Yield (CARD) that optimizes the yield of the competition sportsmen, fan or professional. Presently work is shown the historical development of the sport and the main models of existent CARD initially in our country and in the countries with more competitive level. Likewise the general concepts of sport of high yield are revised like they are their functions, their objectives and their phases; the current situation of the sport and the sportsman in Colombia emphasizing in the general knowledge of the programs settled down by the departmental organisms as they are the Inderbú and Indersantander; and the most outstanding administrative foundations for our project like they are the administrative theories and the planeación process. This way he/she settles down the organization and administration for the good operation of a CARD in the municipality, showing the guidelines (mission, vision, values and objectives), the services that ready to the sport community, and their organizational structure, specifying in their organization (flowchart), administrative processes (managerial, misionales and of support), operation (manual of processes, manual of functions) infrastructure, system of information, administration indicators and their costs (in investment and in operation). We look for that this proposal of administrative and organizational design of the CARD allows to establish a center of specialized services of health that is the service of the professional sportsmen and fans that look for to improve its health and competitive

    El trauma en Colombia es la primera causa de mortalidad prematura con una incidencia mayor en los hombres jóvenes. El objetivo de este trabajo es determinar la asociación de la severidad del trauma con la morbimortalidad en pacientes con lesiones osteomusculares con y sin traumas asociados atendidos en el servicio de ortopedia y traumatología del Hospital Universitario de Santander. Métodos: Se realizó un estudio observacional analítico de corte transversal aplicando la escala de severidad New Injury Severita Score (NISS), ingresando al estudio únicamente quienes tuvieran trauma osteomuscular con 9 o más puntos. Resultados: Al estudio ingresaron 140 pacientes, 120 aceptaron ingresar al estudio, sin embargo solo 105 completaron seguimiento. 84 pacientes fueron hombres (80%) y 21 fueron mujeres (20%). El mecanismo de trauma más frecuente fue la lesión asociada al tránsito. . Las fracturas más frecuentes fueron fracturas a nivel de fémur, seguido de las fracturas nivel de la tibia. Durante la realización del estudio se presentaron 14 fallecimientos que corresponden al 13,3% del total de la muestra, en estos pacientes los puntajes de severidad de la escala del NISS fueron los más altos en comparación a quienes sobrevivieron al politraumatismo aunque no se encontró una asociación estadísticamente significativa. Discusión: La morbimortalidad asociada al trauma de la población joven presenta su mayor distribución en el género masculino dando como resultado mayor número de años de vida potencialmente perdidos. Se observa con este estudio mortalidad en los pacientes que tuvieron mayor puntuación en la escala del NISS lo cual alerta a los servicios de trauma hacia el uso de las escalas de severidad como parte de la prevención en mortalidad y el ingreso a UCI tempranamente de los pacientes. _EspecializaciónEspecialista en Ortopedia y TraumatologíaIn Colombia trauma is the first cause of premature mortality with higher incidence in young male adults. The objective of this work is to determinate the association of the injury severity with the morbi-mortality in patients with or without associated osteomuscular traumas in the department of orthopedics and traumatology at the University Hospital of Santander. Methods: An observational, analytical, cross-sectional study was conducted applying the New Injury Severity Score (NISS), only including in the study those how had osteomuscular trauma with 9 or more points. Results: 140 patients were included in the study, 120 accepted to be included, however only 105 completed the follow up. 84 patients were men (80%) and 21 were women (20%). The most frequent trauma mechanism was associated transit trauma. The most common fractures were at the femur, followed by the tibia. During the study there were 14 deaths that correspond to 13, 3% of the total sample, in these patients the severity score of the NISS scale were higher in comparison to those who survived polytraumatism, although no statistically significant association was found. Discussion: The morbi-mortality associated with trauma of young adults shows a higher distribution in males resulting in a larger number of years potentially lost. With this study a mortality in patients that had a higher score in the NISS Scale was observed, this result should alert the trauma departments to use the severity scales as part as prevention in mortality and the early admission of patients to the intensive care unit.

    We 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
