Incidencia de la intervención familiar por medio de un ciclo de Escuela de padres en la motivación escolar de los niños del primero de primaria del Colegio Celestin Freinet. Incidence of family intervention through a cycle of Parent’s School.
No full textResumen
El artículo presenta resultados de la investigación realizada como el trabajo de grado para optar el titulo de psicólogo. El objetivo del estudio fue dirigido a indagar por la incidencia de la intervención familiar mediante un ciclo de Escuelas de Padres en los puntajes en la escala de motivación escolar obtenidos por los niños de primero de primaria del Colegio Celestin Freinet. La investigación llevada a cabo fue de enfoque cuantitativo con un diseño preexperimental con la aplicación de preest y postest, utilizando la escala de motivación escolar diseñada por Klimenko &Alvarez (2009). Los resultados del estudio mostraron un aumento significativo estadísticamente en tres tipos de motivación de cuatro evaluados: motivación epistemológica, motivación de tarea y motivación de logro. En cuanto a la motivación de esfuerzo, aunque hubo un aumento en puntajes al nivel general en el grupo, este no fue significativo estadísticamente. Los resultados obtenidos confirmaron la hipótesis propuesta por el estudio y demostraron que un acompañamiento, basado en la adecuada mediación cognitiva y afectivo-motivacional de las actividades de aprendizaje de los niños tiene un efecto significativo en la respectiva motivación frente al proceso de estudio escolar.

Abstract
The article presents results of research realized as the work of grade of psychologist. The objective of the study was conducted to explore the incidence of family intervention through a cycle of parent schools in school motivation scale scores obtained by children of the first grade of school Célestin Freinet. The research has quantitative approach with experimetal design and application of preest and posttest, using the scale of school motivation designed by Klimenko & Álvarez (2009). The results of the study showed a statistically significant increase in three types of motivation of four evaluated: epistemological motivation, task motivation and achievement motivation. In terms of the motivation of effort, although there was an increase in scores on the general level in the group, this was not significant statistically. The results confirmed the hypothesis proposed by the study and showed that an accompanying, based on appropriate cognitive and emotional and motivational mediation of children's learning activities has a significant effect on respective motivation for the school study process.

Depencencia al smarthphone y su relación con el sentido de vida, bienestar psicológico y autorregulación en una muestra de estudiantes universitarios de Cuba, México y Colombia.
No full textActualmente, el teléfono móvil es el aparato tecnológico más utilizado en el mundo, Según investigaciones realizadas en la Universidad de Hong Kong en el año 2016, señala que cerca del 68% de la población mundial posee un celular. En Colombia, hay en promedio 65,75 millones de celulares activos, lo que sugiere que cada ciudadano tiene entre 1 y 2 celulares, siendo este el dispositivo tecnológico más prevalente en el país (98%), seguido de las laptops y computadoras de escritorio (74%). La presente investigación de naturaleza cuantitativa, descriptiva y no experimental tuvo como objetivo principal caracterizar la dependencia al Smartphone y su relación con el sentido de vida, bienestar psicológico y autorregulación en una muestra de los estudiantes universitarios. Este estudio, contó con una muestra de 276 estudiantes universitarios
de Colombia, México y Cuba, a los cuales se les compartió un formulario el cual contenía preguntas de las siguientes pruebas: el Test de Dependencia al Teléfono Móvil, Brief (TDMB), test de sentido en la vida (Gottfried, 2016), Cuestionario de Autorregulación (CAR) y la Adaptación española de las escalas de bienestar psicológico de Ryff (Díaz et al., 2006). En los cuales se obtuvieron resultados elevados relacionados a las variables: abstinencia, abuso, tolerancia y pérdida de control, indicando una frecuencia significativamente alta en el uso inadecuado y problemático de los teléfonos móviles.Currently, the cell phone is the most widely used technological device in the world. According to research conducted at the University of Hong Kong, about 68% of the world's population owns a cell phone. In Colombia, there are on average 65.75 million active cell phones, which suggests that each citizen has between 1 and 2 cell phones, being this the most prevalent technological device in the country (98%), followed by laptops and desktop computers (74%). The main objective of this quantitative, descriptive, and non-experimental research was to characterize smartphone dependence and its relationship with the sense of life, psychological well-being, and self-regulation in a sample of university students. This study had a sample of 276
university students from Colombia, Mexico, and Cuba, who were given a form containing questions from the following tests: the Mobile Phone Dependence Test, Brief (TDMB), Meaning in Life Test (Gottfried, 2016), Self-Regulation Questionnaire (CAR) and the Spanish Adaptation of Ryff's psychological well-being scales (Díaz et al., 2006). In which high results were obtained related to the variables: abstinence, abuse, tolerance, and loss of control, indicating a significantly high frequency of inappropriate and problematic use of cell phones.Adicciones comportamentales -- Adicción a la tecnología -- Bienestar psicológico (perspectiva C. Ryff) -- Sentido de vida y jerarquía de valores vitales -- Autorregulación
Stability of planar flames as gasdynamic discontinuities
No full textThe stability of a steadily propagating planar premixed flame has been the subject of numerous studies since Darrieus and Landau showed that in their model flames are unstable to perturbations of any wavelength. Moreover, the instability was shown to persist even for very small wavelengths, i.e. there was no high-wavenumber cutoff of the instability. In addition to the Darrieus-Landau instability, which results from thermal expansion, analysis of the diffusional thermal model indicates that premixed flames may exhibit cellular and pulsating instabilities as a consequence of preferential diffusion. However, no previous theory captured all the instabilities including a high-wavenumber cutoff for each. In Class, Matkowsky & Klimenko (2003) a unified theory is proposed which, in appropriate limits and under appropriate assumptions, recovers all the relevant previous theories. It also includes additional new terms, not present in previous theories. In the present paper we consider the stability of a uniformly propagating planar flame as a solution of the unified model. The results are then compared to those based on the models of Darrieus-Landau, Sivashinsky and Matalon-Matkowsky. In particular, it is shown that the unified model is the only model to capture the Darrieus-Landau, cellular and pulsating instabilities including a high-wavenumber cutoff for each

Spatially-localized time dependent solutions including turbulence and their interactions in 2D Kolmogorov flow
No full textIn 2D Kolmogorov flow in small aspect ratio domains, spatially-localized solutions such as kink, traveling or time-dependent kink-antikink pars coexist. However, the conservation of the flow rate in the y direction strongly restrict combination of localized solutions and their positioning. We find that by adding a homogeneous flow U y their positioning is controlled and each of localized solutions including a spatially-localized chaos is isolated. Numerical results suggest that these isolated solutions can be elements constructing a whole flow
