El fascismo español y su sombra en Colombia

Abstract: The main objective of this paper is to carry out a historical, correlational and descriptive study between the bipartisan violence experienced in Colombia during the middle of the 20th century and the Spanish fascism of the 1930s; trying to establish a causal link between these two phenomena, but clarifying that this situation would not be the only trigger of bipartisan violence in Colombia, but one of them, originated in colonial policies and the independence process until the adoption of General Franco’s Spanish fascism ideology in Colombia

Revisión sistemática. Método de rehabilitación del habla para mejorar la fluidez verbal en la tartamudez infantil

Abstract: INTRODUCCION: a traves de una revision exhaustiva de evidencia cientifica con esta investigacion se pretende establecer cual es el metodo mas eficiente para mejorar la fluidez verbal en la tartamudez infantil. METODOS: Revision sistematica utilizando diversas estrategias de busqueda en diversas bases de datos, contando con una ventana temporal de 10 anos. Los estudios incluidos fueron aquellos cuya pesquisa correspondio en seres humanos, poblacion infantil, con indicadores de produccion del habla asociadas a la tartamudez y a sus procesos de rehabilitacion. RESULTADOS: en la actualidad los profesionales de Fonoaudiologia en Latinoamerica estan adoptando de forma empirica y basado en la praxis, varias estrategias de rehabilitacion para usuarios con alteraciones de la fluidez verbal, disenadas para rehabilitar el patron de habla de la tartamudez de la poblacion infantil europea, sin embargo la evidencia cientifica demuestra la eficiencia y la eficacia de un metodo de tratamiento denominado programa Lidcombe. ANALISIS Y DISCUSION: para el infante es de suma importancia expresar el lenguaje verbal de manera fluida, es ahi donde nace la necesidad del Fonoaudiologo en buscar estrategias estandarizadas que garanticen la rehabilitacion completa de los mecanismos del habla patologica. CONCLUSIONES: el respaldo teorico determina que existen pocos metodos de rehabilitacion para la intervencion de la tartamudez infantil que sean de facil acceso para los terapeutas, entre ellos se encontro que existe uno que permite tratar las caracteristicas del habla de la poblacion infantil australiana y que ha sido aplicado y adaptado en algunos paises del continente europeo y asiatico.

Structural, magnetic, and electrical features of the Nd2SrMn2TiO9 perovskite-like compound

Abstract: The synthesis process of the polycrystalline ceramic compound Nd2SrMn2TiO9 by means of the solid-state reaction procedure is reported. The crystalline structure was analyzed through X-ray diffraction experiments in the Bragg–Brentano recipe. The Rietveld refinement of the diffraction pattern by using the GSAS code shows that this material crystallizes in an orthorhombic structure, space group Pnma (#62), with lattice parameters a = 5.4764(6) Ǻ, b = 7.7468(6) Ǻ, and 5.4810(6) Ǻ. The surface morphology was studied by scanning electron microscopy images, which evidence the formation and compacting of grain with mean size 352.63 nm. Semiquantitative compositional analysis performed by means of Energy Dispersive X-ray Spectroscopy shows the stoichiometric composition of the samples. Measurements of magnetization as a function of temperature reveal that this compound has a ferromagnetic behavior. The analysis with the Curie equation permitted to establish an effective magnetic moment μeff = 4.33 μB, which is 95.7% in agreement with the theoretical value expected from the Hund's rules. Measurements of DC resistivity as a function of temperature show a conductor behavior below the Curie temperature and insulator above. Evidences of a nonlinear response as a function of frequency with high values of relative dielectric constant reveal the occurrence of giant dielectric constant with ϵr = 6480 for ν = 100 Hz.

Cognitive and psycho-social benefits associated with upper limb motor rehabilitation performed through a playful activity in young people

Abstract: A playful tool was developed to be used in a game activity, with characteristics of a rehabilitation therapy of upper limb, tested with 50 young people between 16 and 22 years old. The prototype consisted of a remote control and a toy car that had the function of moving in several directions (forward, back, right and left), simultaneously with the movements made by the player of extension, bending, supination and pronation of three segments of the upper limb (shoulder girdle, arm and forearm). The toy car was mobilized across a track, divided into three levels of difficulty. It was identified that the prototype complies with the requirements of an activity within the framework of rehabilitation, since the principles of the Neurodevelopment model are taken into account; there are levels of complexity that promote the acquisition, training and strengthening that may have adjacent benefits such as concentration at the cognitive level and high motivation in their social environment.

Strengthening of Reasoning Levels in Higher Education Students through the Use of Learning Strategies (Problem-Based Learning and Collaborative Learning) Using ICT's.

Abstract: espanolIntroduccion. En el contexto educativo, las tecnologias de la informacion y la comunicacion (TIC) implican un cambio de paradigma en los procesos de ensenanza-aprendizaje, tanto en la renovacion de las practicas y contenidos, como en la manera de evaluar la apropiacion de los conocimientos. En este sentido, en la presente investigacion se analiza la incidencia que tiene la implementacion de las estrategias didacticas, Aprendizaje Basado en Problemas (ABP) y Aprendizaje Colaborativo (AC) en el fortalecimiento de los niveles de razonamiento, a traves de la integracion de la tecnologia a la educacion superior. Metodo. La investigacion presenta enfoque cuantitativo, con diseno cuasiexperimental en la cual participaron 35 estudiantes de la Universidad Colegio Mayor de Cundinamarca en Bogota - Colombia, a quienes se les aplico un pre y un post test, usando el Lawson´s Classroom Test of Scientific Reasoning Resultados. Con la informacion obtenida y al realizar un analisis estadistico descriptivo es posible afirmar que un 85.29% del total de estudiantes aun se encuentran en el nivel de razonamiento concreto, sin embargo aquellos estudiantes que participaron en la estrategia didactica de ABP presentaron una mejora en su nivel de razonamiento, pasando del nivel de razonamiento concreto al nivel formal y post-formal. Conclusiones. Los resultados obtenidos permiten concluir que no existe una diferencia estadisticamente significativa en la mejora de las habilidades de razonamiento antes y despues de la aplicacion de las estrategias didacticas, ya que al comparar el razonamiento de los estudiantes se evidencia que en su mayoria aun se encuentran en el nivel de razonamiento concreto, es decir, que permanecen ligados a una realidad empirica con un pensamiento pre-operacional. EnglishIntroduction. In the educational context, information and communication technologies imply a paradigm shift in learning-teaching processes both in the renewal of knowledge and practices and in evaluating knowledge appropriation. In this sense, in the present paper we analyze the incidence of the implementation of didactic strategies, problem-based learning (PBL) and collaborative learning (CL) in the strengthening of reasoning levels through the integration of technology to higher education. Method. This research presents a quantitative approach and a quasi-experimental design in which 35 students of the “Colegio Mayor de Cundinamarca” (Bogota, Colombia) participated: they were given a pre and a post-test using the Lawson’s Classroom Test of Scientific Reasoning. Results. With the collected information and after performing a descriptive statistical analysis it is possible to affirm that an 85.29% of total students are still at concrete reasoning level. However, those students that participated in the didactic strategy of PBL showed improvement in their reasoning level, going from concrete reasoning level to formal and post-formal level. Conclusion. The results obtained allow us to conclude that there is no statistically significant difference in the improvement of the reasoning skills before and after the application of the didactic strategies, since when comparing students reasoning it is evident that most of them are still in the concrete reasoning level, that is, they remain linked to an empirical reality with a pre-operational thinking.
