las redes sociales de internet ¿una nueva adicción? / The use of social networking websites is a new addiction?

The use of social networking websites, fixed and mobile internet, has been placed in a situation of global explosion such a degree where the user behaviour is raising some concerns in the mental health community. The article shows the attractiveness of social networks and their consequences. In order to reduce and even eliminate the disorders that sometimes cause the misuse of social networks offer some recommendations to follow, like training of network access, application of codes of conduct and codes of best practices and patterns of use

La protección de datos: la privacidad en la Biblioteca de la Universidad Complutense de Madrid

The object of the article is to give to know the Data Protection of personal character in the library of the Complutensian University of Madrid due to the nonexistence of records on the topic. In order to improve the treatment of the private information resting on the creation of the Protection unit of Information of 2006. It has been had as methodology of base, primary sources, the laws that regulate it, polls and you poll workers and users, monographs and specializing magazines. It has wanted to put of manifest on the need of a real capture of conscience before the problem of the privacy. It concludes with the need of creation of a code of conduct for the rigorous treatment of the personal information where there are gathered additional coverages that assure the confidentiality and reserve of the users

La cuarta dimensión: ¿geometría que no podemos ver?

La geometría tridimensional nos permite entender y razonar sobre nuestro entorno cotidiano. Más aún podemos, conocer, manejar y trabajar con los distintos objetos que cada día nos encontramos, ya sean rectas, planos, esferas o poliedros. Sin embargo, ¿es nuestro mundo realmente un espacio tridimensional? ¿Podemos sólo percibir estas tres dimensiones (alto, ancho y largo)? O contrariamente, ¿existe una cuarta dimensión con sus correspondientes objetos geométricos? Y, en este caso, ¿es la mente humana capaz de imaginarlos

Proyecto de intervención Invernadero de Exhibición (Real Jardín Botánico Madrid) : análisis y modificación de los materiales del edificio para la mejora de su ciclo de vida

La intervención consistirá en una sustitución parcial o total de los materiales preexistentes con el objetivo de poder reducir en lo posible el consumo energético y la huella de CO2 producidas por el edificio debido a estos materiales, a su procesamiento, a su transporte y su fin de vid

A Long-Life Predictive Guidance with Homogeneous Competence Promotion for University Teaching Design

Even though planning the educational action to optimize student performance is a very complex task, teachers typically face this challenging issue with no external assistance. Previous experience is, in most cases, the main driving force in curriculum design. This procedure commonly overlooks the students’ perception and weakly integrates the students’ feedback by using a non-systematic approach. Furthermore, transverse competences are, unfortunately, typically omitted in this procedure. This work suggests the use of a predictive tool that determines the optimal application time of different methodological instruments. The suggested method can be used for an infinite number of scenarios of promoted competences. The results can be regarded as a guide to modify the course structure, but, more importantly, it offers valuable information to understand better what is occurring in the teaching-learning process and detect anomalies in the subject and avoid the students’ exclusion. The predictive scheme simultaneously considers the teacher’s perspective, the student’s feedback, and the previous scores in a systematic manner. Therefore, results provide a broader picture of the educational process. The proposal is assessed in a course of Electrical Machines at the University of Malaga during the academic year 2021–2022.This research was funded in part by the Spanish Government under the Plan Estatal with the reference PID2021-127131OB-I00, in part by the Junta de Andalucia under the grant UMA20-FEDERJA-039 and in part by the Ministry of Science, Innovation and Universities under the Juan de la Cierva grant IJC2020-042700-I.

Lagrangian submanifolds in complex space forms satisfying an improved equality involving δ(2,2)

It was proved in [8, 9] that every Lagrangian submanifold M of a complex space form M˜ 5 (4c) of constant holomorphic sectional curvature 4c satisfies the following optimal inequality: δ(2, 2) ≤ 25 4 H 2 + 8c, (A) where H 2 is the squared mean curvature and δ(2, 2) is a δ-invariant on M introduced by the first author. This optimal inequality improves a special case of an earlier inequality obtained in [B.-Y. Chen, Japan. J. Math. 26 (2000), 105-127]. The main purpose of this paper is to classify Lagrangian submanifolds of M˜ 5 (4c) satisfying the equality case of the improved inequality (A).Fundación Cámara (Universidad de Sevilla)National Natural Science Foundation of Chin
