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
Conocimientos del pie diabético en personal médico en formación en la ciudad de Medellín
Get PDFRESUMEN: Justificación: El pie diabético es el causante de las amputaciones no traumáticas, hasta en el 85% de los casos, llevando a discapacidades importantes, es por esto, que el personal de la salud debe estar capacitado para el reconocimiento temprano de esta patología así como para el adecuado tratamiento. Nos planteamos objetivar el conocimiento que tienen los médicos en formación del último año de la carrera de medicina de la Universidad de Antioquia para la evaluación del pie diabético y la estratificación del riesgo de amputación.
Métodos: Los participantes fueron estudiantes de medicina del último año de la Universidad de Antioquia, a quienes se les realizó un cuestionario de autodiligenciamiento que constó de 22 preguntas acerca del conocimiento sobre evaluación y estratificación del riesgo de amputación en pacientes con pie diabético.
Resultados: Se contó con 148 participantes. En general los conocimientos sobre la evaluación y estratificación del riesgo son bajos. El 16.9% de los participantes saben realizar la prueba de monofilamento y el 22.3% saben interpretarla. El estudio demuestra no solo desconocen el uso de la prueba de monofilamente, también existe un desconocimiento acerca de los factores de riesgo para amputación; sólo el 20.9% de los encuestados demuestran conocimientos del tema.
Conclusión: De acuerdo a los resultados obtenidos, existe una posible ausencia de espacio y de entrenamiento en la población estudiada, lo que conlleva a niveles de conocimiento bajos y la poca probabilidad de evaluar adecuadamente el riesgo de una amputación por un retraso en el diagnóstico temprano de dicha patología y de un tratamiento oportuno. Los hallazgos de este estudio demuestran la necesidad de implementar estrategias que permitan la capacitación adecuada de los profesionales en formación.EspecializaciónEspecialista en Ortopedia y Traumatologí
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
Pelvic fractures in pediatrics: Clinical and radiological analysis in a trauma center between 2011 and 2020
No full textRESUMEN: Las fracturas de pelvis en población pediátrica son infrecuentes sin embargo son indicador de trauma de alta energía. Existen diferencias anatómicas y fisiológicas con respecto al de la población adulta que se traducen en diferentes tasas de mortalidad, patrones de fractura y lesiones asociadas, estas últimas son las que usualmente dictan el pronóstico. El propósito del presente estudio, es describir las características del trauma de pelvis en población pediátrica atendido en una institución de alto nivel de complejidad de la ciudad de Medellín.
Materiales y métodos: Desarrollamos un análisis retrospectivo de los registros de atención de pacientes pediátricos con trauma pélvico durante 10 años (periodo comprendido entre 2011 y 2020) en un centro de alta complejidad en la ciudad de Medellín, por medio de una base de datos se obtuvo información de las variables relevantes como signos vitales, lesiones asociadas, clasificación radiológica, mortalidad entre otros.
Resultados: Se incluyo un total de 91 pacientes menores de 16 años (59 hombres y 32 mujeres), con promedio de edad de 9,4 años. El mecanismo de trauma más frecuente fue el accidente de tránsito como peatón (44%). Se encontró un 65,1%, de lesiones asociadas extraesqueléticas, siendo el trauma cerrado de abdomen (34,1%) y el encefalocraneano (30,8% ) los más frecuentes y un 38,5% de lesiones ortopédicas asociadas. La mayoría de las fracturas fueron clasificadas como Torode y Zieg tipo III en un 61,5%. Se encontró una mortalidad del 2,2%, ambas muertes secundarias a trauma encefalocraneano grave. Sólo 5 pacientes requirieron procedimientos urgentes para control del sangrado pélvico y la mayoría de los pacientes recibieron manejo ortopedico (85,7%).
Conclusiones: Las fracturas de pelvis en población pediátrica son infrecuentes y aunque la tasa de mortalidad es baja, presenta un índice elevado de lesiones asociadas las cuales son generalmente la causa de muerte. La clasificación de Torode y Zieg aunque es la que utiliza con mayor frecuencia para este tipo de lesiones presenta debilidades importantes en la categorización de los pacientes y al momento de definir un manejo y pronostico.ABSTRACT: Pelvic fractures in the pediatric population are infrequent, however they are an indicator of high-energy trauma. There are anatomical and physiological differences with respect to pelvic trauma in the adult population that translate into different mortality rates, fracture patterns, and associated injuries. They present a high rate of associated injuries, and are those that usually dictate prognosis. The purpose of this study is to describe the characteristics of pelvic trauma in a pediatric population attended at a high-complexity institution in the city of Medellín.
Materials and methods: We developed a retrospective analysis of the care of patients with pediatric pelvic trauma for 10 years (2011-2020) in a highly complex center in the city of Medellín, through a database, information on the was obtained relevant variables such as vital signs, associated injuries, radiological classification, mortality etc.
Results: A total of 91 patients under 16 years of age (59 men and 32 women) were included, with an average age of 9.4 years. The most frequent trauma mechanism was the traffic accident as a pedestrian (44%). 65.1% of associated extraskeletal injuries were found, with blunt abdominal trauma (34.1%) and encephalocranial (30.8%) being the most frequent and 38.5% associated orthopedic injuries. Most of the fractures were classified as Torode and Zieg type III in 61.5%. A mortality of 2.2% was found, both deaths secondary to severe brain injury. Only 5 patients required urgent procedures to control pelvic bleeding and most of the patients received orthopedic management (85.7%).
Conclusions: Pelvic fractures in the pediatric population are infrequent and although the mortality rate is low, it presents a high rate of associated injuries which are generally the cause of death. The Torode and Zieg classification, although it is the most used presents important weaknesses in the categorization of patients and when defining a management and prognosisEspecializaciónOrtopedista y Traumatólog
