ACIMED , 2006,
Abstract: Se abordan los conceptos de biblioteca digital, biblioteca tradicional, biblioteca electrónica, biblioteca híbrida y biblioteca virtual. Se valora un grupo de propuestas, aparecidas en la literatura, para evaluar las bibliotecas digitales y se sistematiza un conjunto de criterios e indicadores para evaluar esta clase de entidades. Los criterios propuestos son: identidad, actualización, accesibilidad, arquitectura de información, servicios de información, colecciones, contenido, dise o de interfase, posicionamiento, sistema de búsqueda y recuperación y usabilidad.

The Status Quo Bias of Bond Market Analysts
Zulia Gubaydullina,Oliver Hein,Markus Spiwoks
Journal of Applied Finance and Banking , 2011,
Abstract: Status quo bias is a systematic cognitive error which makes it difficult forindividuals to make decisions independently of the currently dominant situation.This study pursues the question of whether bond market analysts are affected bystatus quo bias. We evaluated interest rate forecast series from twelve industrialnations. This revealed that, on average, forecasts were much too close to the statusquo – the current interest rate at the time when the forecast was made. With theaid of various analytical procedures it can be shown that the actual extent ofinterest rate changes is systematically and significantly underestimated.
REVASCULARIZACIóN MIOCáRDICA CON AMBAS ARTERIAS MAMARIAS INTERNAS, UN RETO PARA LOS CIRUJANOS CARDIOVASCULARES ACTUALES / Myocardial revascularization with both internal mammary arteries, a challenge for cardiovascular surgeons nowadays
Jean Luis Chao García,álvaro Lagomasino Hidalgo,Francisco Javier Vázquez Roque,Roger Mirabal Rodríguez
CorSalud , 2009,
Abstract: The left internal mammary artery is currently the most common graft in surgical myocardial revascularization. However, in spite of the works showing the effectiveness of the use of both mammary arteries, this technique remains a controversial topic in medical literature nowadays. Among the factors discouraging its use we have the good results of the myocardial revascularization with left internal mammary artery and with saphenous vein, a greater technicaldifficulty and a prolonged surgical time; as well as an increase in sternal complications. The advantages and disadvantages in the use of this procedure are discussed in this work, as well as the results presented by several authors. The surgical technique is also described.
VALIDACIóN TEMPORAL DEL MODELO EUROSCORE PARA LA EVALUACIóN DE LOS RESULTADOS DE LA CIRUGíA DE SUSTITUCIóN VALVULAR MITRAL / Temporary validation of EuroSCORE model for assessing the results of mitral valve replacement surgery

CorSalud , 2013,
Abstract: Resumen: Introducción y objetivos: La estimación del riesgo quirúrgico preoperatorio puede hacerse a través de los modelos matemáticos o escalas de predicción clínica. El objetivo fue validar el Euroscore para evaluar los resultados inmediatos de la cirugía de sustitución valvular mitral. Método: Estudio analítico, longitudinal, de seguimiento prospectivo en 158 pacientes intervenidos quirúrgicamente por enfermedad valvular mitral en el Cardiocentro Ernesto Che Guevara, de Villa Clara, durante los a os 2007-2010. Se calculó el valor del Euroscore a todos los pacientes. La calibración del modelo se evaluó mediante la prueba de bondad de ajuste de Hosmer-Lemeshow. La capacidad de discriminación se analizó a través del cálculo del valor del área bajo la curva COR. Resultados: El valor medio del Euroscore fue de 2,1 con una desviación típica de 1,45. La mortalidad esperada fue del 3,9 %, inferior a la observada que fue de 4,4 %. Los fallecidos presentaron medias del Euroscore de 5,9 vs. 1,95 de los que no fallecieron (p=0.00). Los que tuvieron complicaciones graves mostraron una puntuación media mayor que ante la ausencia de estas, 3,45 vs. 1,84, diferencias estadísticamente muy significativas (p=0.000). El área bajo la curva COR fue de 0,97, con significación de 0.000 para los que fallecieron, y la presencia de complicaciones graves con un área bajo la curva de 0,70 y significación de 0.002. Conclusiones: El Euroscore es confiable para predecir la mortalidad precoz en los pacientes a los que se les ha realizado cirugía de sustitución valvular mitral en nuestro Hospital. El Euroscore no predijo morbilidad grave precoz. / Abstract: Introduction and Objectives: The preoperative surgical risk estimate can be made through mathematical models or clinical prediction scales. The objective was to validate the EuroSCORE in order to assess the immediate results of mitral valve replacement surgery. Method: Analytical, longitudinal study with a prospective follow-up of 158 patients who underwent surgery for mitral valve disease at the Cardiocentro Ernesto Che Guevara, in Villa Clara, from 2007 to 2010. EuroSCORE was calculated in all patients. Model calibration was assessed using the Hosmer-Lemeshow goodness of fit test. The discrimination capacity was analyzed by calculating the value of the area under the ROC curve. Results: The mean EuroSCORE was 2.1 with a standard deviation of 1.45. Expected mortality was 3.9%, lower than the actual mortality that was 4.4%. The deceased had a mean score of 5.9, and those who survived 1.95 (p = 0.00). Those who had serious complica
Rito, cambio cultural y la naturaleza cíclica del turismo
Pinto,Roque;
Estudios y perspectivas en turismo , 2011,
Abstract: this text seeks to present the general model of tourism according to a cyclical perspective, where the activity is understood like a space-time extraordinary and ritualized, considering that the tourist experience is likely to promote changes in the conduct of the tourist on their society of origin, representing a relatively important factor of socio-cultural changes.
Sementes contra a varíola: Joaquim Vás e a tradu??o científica das pevides de bananeira brava em Goa, índia (1894-1930)
Roque, Ricardo;
História, Ciências, Saúde-Manguinhos , 2004, DOI: 10.1590/S0104-59702004000400010
Abstract: in 1914, in the former portuguese colony of goa, india, the physician antónio joaquim vás announced the discovery of a wonderful treatment for smallpox, entailing clinical application of seeds from the bananeira brava (heliconia biahi sw.m.), a plant remedy allegedly derived from indian medical practices. the present article explores the circumstances surrounding the successes and failures of this discovery. the concept of scientific translation is used to interpret the transformation of bananeira bravaseeds into an early twentieth-century remedy for smallpox. this transfer from indigenous use to scientific therapeutics constitutes the creation of a quasi-medicine, that is, a case of 'medium translation'. although these seeds occupy a problematic place within the program of scientific translation, they enjoyed active circulation within science and remained a part of medical practices for combating smallpox.
A voz dos bandos: colectivos de justi?a e ritos da palavra portuguesa em Timor-Leste colonial
Roque, Ricardo;
Mana , 2012, DOI: 10.1590/S0104-93132012000300006
Abstract: this article examines the relations between juridical discourse and ritual practice in the bandos issued by the portuguese colonial government in east timor between the second-half of the nineteenth century and the early decades of the twentieth century. bandos consisted of orders and instructions of command issued by the portuguese governor in dilly and ceremonially transmitted by colonial officers to the populations of the various timorese kingdoms. bandos were a principal tool of colonial governance with regards to indigenous matters. they were used by the portuguese to arbitrate conflicts, punish transgressions and, generally, to institute realities in the timorese world. however, this institution also came to acquire a singular expression in the indigenous cultures, such that the timorese traditional authorities, the liurais, also used it to communicate their own instructions and commands. the essay conceptualizes bandos as colectives of justice and explores their colonial and indigenous variants. in thus considering the bandos as collectives - heterogeneous associations in which both linguistic and non-linguistic elements combine to produce power effects upon the populations - the article proposes a conceptual alternative to linguistic and literary perspectives in the analysis of colonial discourse.
