En la actualidad, los bancos tienen el desafío de ofertar eficientemente sus productos y servicios a través de sus diferentes canales de atención. Una manera para lograr esa eficiencia es a través de políticas apropiadas de gestión de las actividades y los recursos asignados a los diferentes canales, por lo que se hace necesario tener agrupamientos de estos. En este trabajo se realizó una clasificación de los canales bancarios usando el análisis de conglomerados que sirva de referencia para diseñar políticas de gestión de acuerdo con las características físicas y operativas de estos canales. Primeramente, con el apoyo de un grupo de expertos, se preparó la matriz de datos, conformada por 50 tipos de canales bancarios específicos y por variables relacionadas con el tipo y nivel de prestación de servicios. A esta matriz de datos, se aplicó el análisis de conglomerados jerárquico, cuyos grupos fueron resultados de usar como medida de proximidad la distancia euclídea al cuadrado y como método de agrupamiento el algoritmo del vecino más lejano.  Es así, que se obtuvieron cuatro grupos: Grupo 1, conformado por canales presenciales con una alta interacción humana y requieren de manejo de efectivo; Grupo 2, de canales de atención nacional con un nivel funcional específico; Grupo 3, grupo de canales de autoservicio que manejan efectivo; y, Grupo 4, grupo de canales que se caracteriza por el uso de dispositivos de propiedad del usuario, en la mayoría de los casos. De esta manera, con estos resultados se puede establecer políticas de gestión para cuatro grupos de canales bancarios, mejorando la eficiencia en la gestión de estos canales.

Las técnicas de Autocorrelación Espacial (AS) se han utilizado con el objetivo de analizar posibles causas de defunciones producidas por el cáncer de próstata en la población de hombres del Ecuador. Una de las metas para usar estas técnicas es poder identificar cual es la tipología de patrón espacial geográfico de la tasa de mortalidad que se está produciendo, lo cual se estima pueda proveer algunos supuestos que permitan obtener alguna información de los agentes que contribuyen a estos patrones. Para este trabajo se han utilizado los datos obtenidos de las 23 regiones geográficas (provincias) del Ecuador. Se procedió en la aplicación de las técnicas de autocorrelación espacial global, así como las de tipo local (Índice Global de Morán y el estadístico Índice Local de Anselin), se concluyó que en algunas provincias de Ecuador aparece una inusual aglomeración geográfica de la manera en que se muestra distribuida la tasa de mortalidad de cáncer haciendo notar que existe una estructura geográfica que bien podría estar relacionada con algún tipo de factor de riesgo. Los datos utilizados en este trabajo  provienen de los fallecimientos ocasionados por cáncer en los años 2012 a 2015 y cuya disponibilidad puede accederse en el Instituto Estadístico del Ecuador (INEC). Los resultados obtenidos promueven futuros trabajos investigativos en determinar posibles causas de aglomeraciones y asociaciones.

The concept of a ’point’ has been a part of mathematics since its conception,it’s an intuitive idea that every person implicitly knows. Nonetheless, if theconcept is formalized and abstracted there appear new intrinsic properties that aremore complex than the euclidean one of being ’that which has no parts’. Two pathsare explored: the first one using Algebraic Geometry and structures that come fromalgebraic objects and the second one using the language of Category Theory.

Faced with the persistent need to have a complete database and the search to improve the classic techniques for estimating missing data, the research presents a proposed methodology for the imputation of the loss or lack of data, by combining a Segmentation analysis, specifically a Regression Tree and the classic sequential Hot Deck imputation technique. The estimators for the mean, total and variance are calculated, as well as the empirical validation of the proposal, in which unbiased estimators were obtained. The technique is considered to improve the robustness between losses of 5 and 30% of the data, the variability of the data and the relationships between the variables are maintained. Improve estimates over Hot Deck without the use of segmentation.

Emotional education is a key element for children and adolescents’ personal and social development. Emotions acquire a special relevance during the adolescence period. A proper emotional expression in the family will improve the relationship and interaction between its members, and will favour the generation of a good family climate. This work offers an intervention proposal aimed to parents with adolescent children through an educational and practical workshop, in order to improve expression and emotional bond between them, generating a positive coexistence.

One of the fundamental objectives of our education system is the promotion and pursuit of equality. Given that teachers are key to achieving equality, it is essential to ascertain teachers’ knowledge of various gender issues and whether the training they receive is adequate and sufficient. This research is based on a quantitative analysis of an ad hoc survey of 72 primary school teachers. It considers teachers’ knowledge of gender issues in Children's and Young Adults’ Literature, and how they approach them in the classroom. The results show that the main difference between male and female teachers mainly relates to the implementation of activities. The data also confirm the teachers' awareness of their limited knowledge of gender issues and the need for training.  

University dropout is a global and complex phenomenon that occurs as a result of the interaction of multiple academic, economic, affective-motivational variables, etc. Among these, resilience seems important because the transition from high school to university represents a great change in the lives of students, where the ability to adapt to the new environment is essential. This research seeks to analyze the relationship between the resilience of students and the intention to drop out of university. For this purpose, a sample of 440 new students of the Bachelor's Degree in Teaching and the Bachelor's Degree in Psychology, from different Spanish universities, and an ad hoc questionnaire was implemented to measure the intention to drop out and a resilience scale. The results indicate that students who show the intention to drop out have lower scores on the resilience scale. In addition, they show that students of the Degree in Psychology have a higher intention to drop out than students of the Degree in Teaching. For this reason, the implementation of tools that promote resilience is suggested as a preventive measure for dropping out of university.

Through the very brief account of a part of his professional biography as a teacher, the author exemplifies what has been his conceptualization of theory-practice relationships, articulated from the interactions between study, reflection and action, shaping small pedagogies situated between university academics and teaching in the classrooms of schools and institutes. An intermediate space that is presented as the most appropriate for the permanent professional development of a reflective subject who is equally attentive to academic knowledge about education and to the tasks and circumstances of the classroom, the center and the educational system. But at the same time it implies (it must be said) a difficult professional identity, as it lacks an institution, professional field and historically constituted reference group.

During the period from March to May 2020, a period of confinement took place in Spain due to the COVID-19 pandemic. Among other relevant social changes, improvised online teaching was adopted to replace face-to-face teaching throughout the education system. The objective of this research was to analyze the possible mediating role of the school engagement between the support of the institution, peers and professors, and the academic satisfaction of university students with the teaching received during the COVID-19 lockdown. The participants were 157 students who were studying various disciplines from first to fourth year of undergraduate and master's degrees at the University of Valencia. An online questionnaire was administered to collect data on the proposed variables. A structural equation model with latent factors was applied to test the hypotheses. An important mediating effect of school engagement was observed for the academic satisfaction of the students, and an outstanding direct influence of the support of the teaching staff on the academic satisfaction of the students. In this work, empirical evidence is provided on the relationship between social support and academic satisfaction of Spanish university students mediated by school engagement during the months of lockdown due to COVID-19. Therefore, relevant information is offered for the elaboration of a specific methodology to apply quality online teaching.
