Yosoydiverso. Estrategia transmedia de comunicación

Abstract: El articulo presenta la metodologia, desarrollo y resultados del proyecto #Yosoydiverso, estrategia de comunicacion transmedia a la que se vinculo la comunidad academica de artes y diseno de la ciudad de Bucaramanga-Colombia. Este proyecto genero la participacion ciudadana, quienes expresaron y reflexionaron en torno a la discriminacion y la exclusion. Se encuentran relatos de jovenes y adultos que han sido discriminados por ser altos, bajos, gordos o delgados; por ser campesinos o pobres; por provenir de una determinada region, por tener tatuajes, un determinado tono de piel o preferencia sexual. Se hace urgente movilizar las percepciones humanas hacia sociedades mas integradoras en la que la diversidad sea un gran valor. DOI: https://doi.org/10.33571/revistaluciernaga.v10n19a6

Resource allocation model for a computer system

Abstract: This article describes a simulation for resource allocation. As a particular case, it describes how would be the assignment in an ad hoc network. We present the results of a simulation allocating resources from one system (communications network) to another system (agent collections). In the description of the model first shows the behavior of the allocation of resources towards the nodes depending on the usefulness of the network and the satisfaction of the agents. Based on the mathematical model of the tragedy of the commons, the behavior of the system is shown. The usefulness and satisfaction of the system are measured. Resource allocation is modeled as an interaction. The computational model Interaction Nets is used as the basis of the simulation.

Aspectos generales de la agresión con ácidos, un delito que deja huella

Abstract: La conducta de lesiones personales que causan una deformacion en el rostro a traves del lanzamiento de acidos ha trascendido en la sociedad y evolucionado en la normatividad colombiana estableciendo parametros claros de aumento de penas y restricciones. Conforme a la recoleccion de datos derivados de la investigacion de tipo cualitativo, que tiene un alcance descriptivo y explicativo en el cual se realizo un analisis que evidencio el origen, los conceptos, las caracteristicas y la importancia del avance normativo de este delito que paso de ser una lesion personal a ser un delito autonomo.

Estructura dimensional de una escala de actitudes hacia la estadística en estudiantes universitarios de segundo y tercer semestre de la facultad de Psicología de la Universidad Piloto de Colombia

Abstract: Objective: to analyze the dimensional structure of Auzmendi’s Scale of Attitudes toward Statistics (1992). Method: it was developed and applied as a descriptive research to 109 students of second and third semester of Psychology at Piloto University of Colombia selected by census. Results: a factorial solution was performed based on four dimensions and fifteen items, with capacity to explain the 63.29% of the instrument variance and with a reliability Cronbach's Alpha coefficient equal to .846. Conclusion: dimensional structures proposed by Auzmendi are not estimable.

Electrochemical characterization of corrosion in materials of grounding systems, simulating conditions of synthetic soils with characteristics of local soils

Abstract: The integrity of structures buried in earthing becomes relevant when analysing maintenance and replacement costs of these systems, as the deterioration is mainly due to two factors, namely: the failures caused in the electrical systems, which are due to the system. Failure in earthing due to corrosion at the interface cause an alteration in the structure of the component material and generates an undesirable resistivity that cause malfunction in this type of protection systems. Two local soils were chosen that were categorized as sandy loam and clay loam type, whose chemical characteristics were simulated by means of an electrolyte corresponding to the amount of ions present determined by a soil characterization based on the CICE (effective cation exchange coefficient), which allows us to deduce the percentage of chloride and sulphate ions present for the different levels established in the experimental matrix. The interaction of these soils with grounding electrodes is a complex problem involving many factors to consider. In this study, the rates and corrosion currents of the different soils on two types of electrodes, one copper and the other AISI 304 stainless steel, were approximated by electrochemical techniques such as potentiodynamic curves and electrochemical impedance spectra. Considerably higher speeds were determined for copper-type electrodes when compared to those based on steel. However, from the Nyquist diagrams, it was noted that copper electrodes have better electrical performance than steel ones. The soil with the highest ionic activity turned out to be the sandy loam. The clay loam soil presents a tendency to water retention and this may be the reason for the different behaviour with respect to ionic mobility. The diffusion control in the steel seems to alter the ionic mobility because its corrosion rates proved to be very similar regardless of the type of soil chemistry. In general, corrosion rates fell since tenths of a millimetre every year to the hundredths of a millimetre in the case of the steel-based electrode, which are relatively small corrosion rates.
