Incorporation of social networking and application of responsive design for moodle

El objetivo de la investigación fue explorar la integración de redes sociales y de plantillas de diseño responsivo para el acceso a contenidos de la plataforma Moodle. El enfoque de investigación es exploratorio y de alcance transversal. Los resultados evidencian que Moodle es una plataforma con suficiente flexibilidad para dar soporte a la incorporación de componentes desarrollados por terceros, como es el caso de la red social Facebook. Además, soporta la incorporación de plantillas con diseño adaptativo permitiendo generar un entorno de uso independiente del dispositivo móvil; de descarga de aplicaciones, navegadores y sistemas operativos.The objective of the research was to analyze the integration  of  social  networks  and  templates  with responsive design for Moodle. The research approach is exploratory and cross-sectional. The results provide evidence to show that Moodle is a flexible platform to support the incorporation of components developed by third parties, such as the social network Facebook, as well as supporting the incorporation of adaptive design templates to create an environment allowing independent use of  the  mobile  device,  download  applications,  browsers and operating systems

Effects of stand variables on stemflow and surface runoff in pine-oak forests in northern Mexico.

The flow of water in temperate forests depends on the amount of precipitation, type of soil, topographic features, and forest cover, among other factors. Unlike the first three, forest cover can be modified by silvicultural treatments, the effects of which manifest in the quality and quantity of water, as well as in the transport of sediments and soil nutrients. The objective of this study was to analyze the effect of some stand variables on surface runoff and stemflow in pine-oak forests of northern Mexico. The stand variables included tree diameter at breast height, basal area, canopy cover, and volume. They were collected in eight 0.1-ha circular plots, measured in 2016 and re-measured in 2018. Nonlinear quantile regression was used to determine the best-fit relationships between the variables. Results indicated that surface runoff was most closely and inversely related to basal area. Stemflow was related to diameter at breast height, while showing no statistical significance. A stemflow funneling ratio did show an inverse, statistically-significant relationship with diameter at breast height. These results can help determine best forest management regimes compatible with the quantity and quality of water fluxes in this type of ecosystem

Experiencias emocionales de estudiantes universitarios en la clase de cálculo I

En el proceso de aprendizaje/enseñanza de la matemática interfieren un sinfín de variables, las cuales determinan el aprendizaje significativo de los estudiantes, entre estas variables se encuentran las variables afectivas. En esta investigación se abordó la temática de experiencias emocionales, teniendo como principal objetivo dar a conocer las emociones que un estudiante vive en un aula de clases, así como relacionar el contenido matemático con dichas experiencias

Kynurenine and Hemoglobin as Sex-Specific Variables in COVID-19 Patients: A Machine Learning and Genetic Algorithms Approach

Differences in clinical manifestations, immune response, metabolic alterations, and outcomes (including disease severity and mortality) between men and women with COVID-19 have been reported since the pandemic outbreak, making it necessary to implement sex-specific biomarkers for disease diagnosis and treatment. This study aimed to identify sex-associated differences in COVID-19 patients by means of a genetic algorithm (GALGO) and machine learning, employing support vector machine (SVM) and logistic regression (LR) for the data analysis. Both algorithms identified kynurenine and hemoglobin as the most important variables to distinguish between men and women with COVID-19. LR and SVM identified C10:1, cough, and lysoPC a 14:0 to discriminate between men with COVID-19 from men without, with LR being the best model. In the case of women with COVID-19 vs. women without, SVM had a higher performance, and both models identified a higher number of variables, including 10:2, lysoPC a C26:0, lysoPC a C28:0, alpha-ketoglutaric acid, lactic acid, cough, fever, anosmia, and dysgeusia. Our results demonstrate that differences in sexes have implications in the diagnosis and outcome of the disease. Further, genetic and machine learning algorithms are useful tools to predict sex-associated differences in COVID-19

Local perspectives and regional problems of security and justice in Latin America

La obra que el lector tiene en sus manos es una invitación a revisar y a transformar la relación de los habitantes de los países de América Latina con el sistema estatal de administración de justicia y con las manifestaciones comunitarias y ancestrales de justicia. El libro tiene una perspectiva empírica, que es consciente del impacto negativo que tienen los conflictos, la violencia y la criminalidad en la vida de las personas y, a su vez, propositiva, que busca valorar los procesos sociales de resistencia y las practicas innovadoras de las comunidades y los estados en busca de la equidad y justicia material.The work that the reader has in his hands is an invitation to review and transform the relationship of the inhabitants of the countries of Latin America with the state system of administration of justice and with community and ancestral manifestations of justice. The book has an empirical perspective, which is aware of the negative impact that conflicts, violence and crime have on people's lives and, at the same time, is proactive, which seeks to value the social processes of resistance and the innovative practices of communities and states in search of equity and material justice.Bogot
