Evaluation of the effectiveness of self-regulation of learning in virtual environments in higher education
No full textIntroducción: La autorregulación del aprendizaje es la capacidad del estudiante para asumir el control de su propio aprendizaje, mediante la elección consciente de estrategias cognitivas y metacognitivas. En la virtualidad esta competencia se constituye en un factor determinante para alcanzar autonomía que puede mejorar las interacciones del estudiante en los entornos virtuales de aprendizaje. Objetivo: evaluar la eficacia de la autorregulación del aprendizaje en los entornos virtuales en programas de pregrado y posgrado de una universidad colombiana. Metodología: cuantitativa con estadística descriptiva y correlacional aplicada a tres momentos del acto formativo y a tres fases de la autorregulación del aprendizaje. La muestra fue de ocho profesores y 533 estudiantes de seis programas académicos virtuales. Resultados: se encontró una ruptura en los tres momentos del acto formativo, lo que limitó el desarrollo del ciclo de autorregulación del aprendizaje. Las variables: previsión, ejecución, autorreflexión fueron significativas para su medición y las de mayor influencia en los procesos autorregulatorios se relacionaron con el nivel de formación en tres pregrados y tres posgrados. Para la universidad estudiada el Índice de Autoeficacia tuvo un valor de 0.31. Conclusiones: se evidencia una problemática asociada a factores pedagógicos, tecnológicos, comunicativos y/o de gestión educativa, que reducen la intencionalidad formativa para que el estudiante alcance autonomía. Es importante investigar y medir de manera holística la autorregulación del aprendizaje en entornos virtuales como proceso y acto formativo. El índice de autoeficacia es aplicable en otras investigaciones en entornos virtuales de aprendizaje.Introducction: Self-regulated learning is the student’s ability to take control of their own learning, through the conscious choice of cognitive and metacognitive strategies. In virtuality, this competence becomes a determining factor to achieve autonomy that can improve student interactions in virtual learning environments. Objetive: evaluate the effectiveness of self-regulation of learning in virtual environments in undergraduate and graduate programs from a Colombian university. Methodology: quantitative with descriptive and correlational statis- tics applied to three moments of the training event and three phases of self-regulation of learning. The sample was eight teachers and 533 students from six virtual academic programs. Results: A rupture was found in the three moments of the training event, which limited the development of the self-regulation cycle of learning. The variables: foresight, execution, self-reflection was significant for measurement and those with the greatest influence on self-regulatory processes were related to the level of training in three undergraduate and three postgraduate degrees. For the university studied, the Self-Efficacy Index had a value of 0.31. Conclusions: There is evidence of a pro- blem in educational management associated with pedagogical, tech- nological, communicative and/or management factors, which reduce the formative intention so that the student achieves autonomy. It is important to holistically investigate and measure the self-regulation of learning in virtual environments, as a process and formative act. The self-efficacy index is applicable in other investigations in virtual learning environments

Gender-based differences in psychological, nutritional, physical activity, and oral health factors associated with stress in teachers
No full textThe aim of this study was to analyze gender differences in stress-related factors among active teachers. A cross-sectional study was conducted to examine gender disparities in psychological, nutritional, physical activity, and oral health factors and how these habits correlate with stress and burnout in their work environment. The sample comprised 1037 teachers from Spain, Colombia, and Chile, consisting of 40.1% men and 59.9% women, with an average age of 41 years and teaching experience of 11.8 ± 9.2 and 12.2 ± 8.7 years, respectively. They were evaluated using a compilation of questionnaires with the objective of analyzing gender differences in habits that are associated with stress levels in teachers. The findings revealed that men had significantly higher levels of depersonalization and personal accomplishment, whereas women exhibited higher levels of perceived stress and conscientiousness. Regarding nutritional habits, results were more positive for women, and men exhibited healthier functional habits by engaging in more weekly sports. Regarding oral health habits, women had better oral hygiene practices, brushing their teeth more frequently. However, women showed a higher tendency to smoke than their male counterparts. We conclude that there are notable gender differences that can provide insights for developing strategies to enhance the overall well-being of teachers
Lean philosophy “Quick Wins”: a case study in a non-alcoholic beverage company
No full textThe non-alcoholic beverage industry stands out as one of the fastest-growing agroindustrial sectors, despite the difficulties generated by the COVID-19 pandemic, with optimistic projections in the coming years. Its importance lies in the economic, productive, and social contribution and the social responsibility programs companies carry out for their interest groups. However, the industry faces challenges such as competition, government restrictions related to the environment, quality and safety of products and processes, and product diversification due to changes in consumer demand for more natural products. Therefore, companies in the non-alcoholic beverage sector must establish and implement appropriate strategies to maintain the quality of their products, optimize costs, and satisfy continuous and changing customer requirements. The present study presents the application of the Lean Manufacturing methodology as a philosophy of continuous improvement aimed at achieving early victories in terms of quality and productivity. It costs through three-phase methods, which consisted of 1) diagnosis of the current state of the production line, 2) identification of the types and sources of waste that affect the efficiency and quality of the process, 3) Action Plan and implementation of appropriate Lean Manufacturing techniques and, 4) Evaluation of the impact of the improvement proposal on time, cost, quality, and customer satisfaction indicators. The case study is presented in the process of changing the flavor of a non-alcoholic beverage company, which is of high value in Latin America and is part of one of the largest companies worldwide. The results evidenced significant improvements in time lost due to flavor change, which went from 234 min to 170 min, decreased costs due to a reduction in time lost in flavor change went from USD 258,750 to USD 203,500, and improvement in a corporate culture focused on quality and continuous improvement, with an impact on reducing non-value added times or waste time
Redes personales y apoyo social en la pandilla juvenil Los Repelentes de la localidad sur oriente del barrio Moderno del Distrito de Barranquilla
No full textEn el presente estudio se llevó a cabo un análisis de las redes personales y el apoyo social en el contexto de la violencia juvenil, centrándose en el grupo "Los Repelentes" con un total de veinte integrantes en la localidad sur oriente del barrio Moderno del distrito de Barranquilla. La metodología aplicada fue descriptiva, se identificaron actores relevantes, se discriminó la estructura de las redes y se describió el apoyo social. Los resultados de la investigación revelan la formación de un subgrupo entro de la red estudiada, en los cuales los miembros demostraron una alta interdependencia entre sus miembros, quienes se identificaron y apoyaron en función de sus intereses y características similares. Asimismo, se identificaron actores clave dentro de la red que ejercen una influencia significativa, facilitando el intercambio de consejos y recursos financieros. La investigación también mostró variaciones mínimas en la densidad de la red, y el hallazgo de que gran parte de su apoyo provenía de (pocas) personas de fuera de la red, entre las que las mujeres tenían un mayor protagonismo. Estos hallazgos aportan elementos que requieren atención para favorecer en la academia una investigación más exhaustiva, que ayude a comprender la dinámica de la violencia juvenil en contextos urbanos, destacando la importancia de las relaciones interpersonales y el apoyo social en la formación y mantenimiento de pandillas juveniles.In the present study, an analysis of personal networks and social support in the context of youth violence was carried out, focusing on the group "Los Repelentes" with a total of twenty members in the south-eastern town of the Moderno neighborhood of the district. from Barranquilla. The methodology applied was descriptive, relevant actors were identified, the structure of the networks was discriminated and social support was described. The results of the research reveal the formation of a subgroup within the network studied, in which the members demonstrated a high interdependence among their members, who identified and supported each other based on their similar interests and characteristics. Likewise, key actors within the network who exert significant influence were identified, facilitating the exchange of advice and financial resources. The research also showed minimal variations in the density of the network, and the finding that much of its support came from (few) people outside the network, among whom women had a greater role. These findings provide elements that require attention to encourage more exhaustive research in academia, which helps understand the dynamics of youth violence in urban contexts, highlighting the importance of interpersonal relationships and social support in the formation and maintenance of youth gangs.Lista de Tablas y figuras7-Figuras7- Introducción 9- Planteamiento del problema 9- Pregunta problema 10- Antecedentes Científicos 11-Justificación del estudio 13-Objetivo 15-Objetivo General 15-Objetivos Específicos 15-Marco de Referencia 16- Antecedentes 16- Internacionales 17- Antecedentes Nacionales 23- Marco teórico 29-Redes personales 29- Referentes Históricos 40- Referentes contextuales 43- Método 47- Diseño 48- Participantes 48- Criterios de Inclusión 48- Procedimiento 49-Contacto con los participantes 50- Administración del cuestionario 50- Detalles del cuestionario 50- Duración del trabajo de campo 51-Análisis de datos 51- Consideraciones Éticas 51-Resultados 52- Actores más relevantes de las Redes Personales de los jóvenes pertenecientes al grupo de estudio 53-Composición de la Red en el contexto de la Pandilla "Los Repelentes"54 - Grafos de Redes 56- Estructura de las redes 68 - Densidad 68- Análisis relacionado con elementos de los alteri 73 -Apoyo social en las redes personales de los participantes 75 - Discusión 83 - Conclusiones 86- Recomendaciones 89- Referencias 92- Anexos 104Especialista en Intervención PsicosocialMaestrí
A hypoplastic model for pre- and post-liquefaction analysis of sands
No full textThis article proposes an extended constitutive model for liquefaction analysis of sands. The proposed model is formulated based on the hypoplastic model for granular soils by von Wolffersdorf (1996), enhanced with Intergranular Strain Anisotropy by Fuentes et al. (2019), which is usually referred to as ISA-hypoplasticity. The proposed extended model includes some modifications that are indispensable for the correct prediction of liquefaction-related analysis: (i) a new Lode-angle-dependent function for post-liquefaction shear strain accumulation, (ii) a modification for fabric change effects, (iii) the theory of the so-called semifluidized state. The first modification allows the model to predict shear strain accumulation in extension and compression during cyclic mobility. The second and third modifications, were initially developed by Liao et al. (2022) for hypoplasticity with conventional intergranular strain based on the pioneer work by Barrero et al. (2020) for Sanisand, and enable the model to reproduce fabric change effects upon loading reversal, and stiffness and dilatancy degradation at low effective stress levels, respectively. With the consideration of the new Lode-angle function, the proposed model realistically predict the increasing shear strain accumulation in both extension and compression without adopting a circular critical state surface, as adopted in Liao et al. (2022). The proposed model was carefully calibrated and validated based on a series of monotonic and cyclic triaxial tests on Zbraslav and Karlsruhe fine sands, considering various testing conditions. The comparison between experimental measurements and numerical predictions of undrained cyclic tests suggests that the proposed model accurately describes the pre- and post-liquefaction stages, as well as the stress attractors
