Technological advances in the information and knowledge society have influenced and transformed economic, social, and educational dynamics. Currently there are many digital gaps related to the access to technology, level of digital literacy, and social use. These gaps vary based on the age of the population and become more noticeable among elders. Digital illiteracy leads to the underusing of technological developments of the 21st century, making it difficult to take advantage of all the possibilities that they offer to our society. This study aims to analyze the level of penetration and use of handheld digital devices, especially the cellular phone, among the adult population. This study is based on the 2016 National Survey of Life Quality in Colombia, elaborated by Departamento Administrativo Nacional de Estadística-DANE, specifically on the module of ownership and use of ICT goods. Results of four age groups are compared, which include 32 year olds or under, from ages 33 to 45 years, 46 to 59 years, and over 60 years. The sample consists of 37047 inhabitants of the Colombian territory, grouped by regions (Antioquia, Bogota, Caribbean, Eastern Central, Orinoquia, Amazonia, Pacific, San Andres, and Valle del Cauca). Data have been analyzed by descriptive and inferential statistical procedures, contingency tables analyses, and logistic regression, in order to identify and know the effect of age on the level of penetration and use of handheld digital devices when comparing results in young adults and elderly people. Findings show that young adults use these technologies to a greater proportion when compared to older adults, showing a significant correlation between age and the increase of digital gaps in access and social use of handheld digital devices. Results also make evident that digital divide in Colombia may be associated to the place of residence, as people who live in rural zones are the ones who suffer greater from inequalities.
The aim of this paper was to create a decision tree (DT) to identify personality profiles of offenders against public safety. A technique meeting this requirement was proposed that uses the C4.5 algorithm to derive decision rules for personality profiling of public safety offenders. The Mini-Mult test was used to measure the personality profiles of 238 individuals. With the test results as our database, a C4.5 DT was applied to construct rules that classify each profile into one of two groups, those without and those with records of offences against public safety. The model correctly classified 80% of the personality profiles and delivered a set of decision rules for distinguishing the profiles by group, and the principal personality profiles were interpreted. We conclude that DTs are a promising technique for analysing personality profiles by their offender or non-offender status. Finally, we believe that the development of a classifying model using DT may have practical applications in the Colombian prison syste
Introducción. La empatía es un elemento importante en la relación médico-paciente, por lo que la formación en empatía de los estudiantes de medicina debe ser un objetivo permanente de los programas universitarios.Objetivo. Determinar los cambios generados por actividades académicas de formación en empatía en dos grupos de estudiantes de medicina.Materiales y métodos. Estudio transversal realizado en dos grupos de estudiantes de medicina a los que se les aplicó la versión en español de la escala de empatía médica de Jefferson. El primero se conformó por 426 hombres y 508 mujeres pertenecientes al curso académico de 2015, mientras que el segundo estuvo constituido por 106 hombres y 239 mujeres del curso académico de 2012. Se realizó un análisis de varianza (ANOVA) y se evaluaron las diferencias entre los años académicos y entre géneros, así como las interacciones entre estos dos factores.Resultados. Aunque en general no se encontraron diferencias significativas en las tres dimensiones evaluadas (p>0.05) para los dos grupos, sí se observaron diferencias en las preguntas 4, 17 y 20, correspondientes a la dimensión Toma de perspectiva, y en la pregunta 6, correspondiente a la dimensión Ponerse en el lugar del otro, ya que los valores fueron mayores (p<0.05) en la cohorte de 2012.Conclusión. Las actividades de formación en empatía establecidas en el plan de estudios del programa de medicina no produjeron cambios significativos, por lo que es necesario evaluar y perfeccionar tanto los contenidos del currículo, como los procesos de enseñanza-aprendizaje relacionados con la formación en empatía del programa de Medicina de la Universidad del Norte.
