Networked Analysis of a Teaching Unit for Primary School Symmetries in the Form of an E-Book
2021
In mathematics education, technology offers many opportunities to enrich curricular contents. Plane symmetries is a topic often skipped by primary teachers. However, it is important and may be worked in attractive ways in dynamic geometry software environments. In any regular classroom there are students with different levels of mathematical attainment, some needing easy tasks while others, particularly mathematically-gifted students, need challenging problems. We present a teaching unit for plane symmetries, adequate for upper primary school grades, implemented in a fully interactive electronic book, with most activities solved in GeoGebra apps. The book allows student to choose which itin…
Cecilio Palomares Acebrón. Notas sobre un maestro conquense
1999
El trabajo se centra en el estudio de la trayectoria del maestro Cecilio Palomares Acedrón, nacido en Cuenca y que tras la finalización de la Guerra Civil se vio forzado a exiliarse. En su casos pudo reconstruir su actividad docente en el Colegio Cervantes de la ciudad de Córdoba, en el mexicano estado de Varacruz.
Vida y obra de un maestro freinetista. El caso de Patricio Redondo
1999
Se analiza la trayectoria del maestro Patricio Redondo, destacado pedagogo español y uno de los introductores de las técnicas del francés Celestín Freinet en España. Se estudian tanto sus actividades en la península como en su exilio en México donde fundó un centro docente y realizó una destacada acción innovadora entre significativos sectores del magisterio de ese país.
Historia de la educación : revista interuniversitaria
1987
Se exponen determinados aspectos relacionados con la infancia durante la Guerra Civil española. En concreto, se analiza el comportamiento de los niños en una guerra fratricida, en la que la infancia está sometida a presiones ideológicas. Expone la dificultad de los niños para entender el hecho de que aquel que ayer era ciudadano de una misma nación, hoy ya no lo sea, o que aquel que fue amigo, hoy deje de serlo. Las colonias de la guerra adquieren características de colonias permanentes, y no sólo para un mes de verano, asumiendo, sobre todo, el carácter de refugio protector de las calamidades de la guerra.

Strictly convergent algorithm for an elliptic equation with nonlocal and nonlinear boundary conditions
2012
The paper describes a formally strictly convergent algorithm for solving a class of elliptic problems with nonlinear and nonlocal boundary conditions, which arise in modeling of the steady-state conductive-radiative heat transfer processes. The proposed algorithm has two levels of iterations, where inner iterations by means of the damped Newton method solve an appropriate elliptic problem with nonlinear, but local boundary conditions, and outer iterations deal with nonlocal terms in boundary conditions.
Implementation and evaluation of medical imaging techniques based on conformal geometric algebra
2020
Medical imaging tasks, such as segmentation, 3D modeling, and registration of medical images, involve complex geometric problems, usually solved by standard linear algebra and matrix calculations. In the last few decades, conformal geometric algebra (CGA) has emerged as a new approach to geometric computing that offers a simple and efficient representation of geometric objects and transformations. However, the practical use of CGA-based methods for big data image processing in medical imaging requires fast and efficient implementations of CGA operations to meet both real-time processing constraints and accuracy requirements. The purpose of this study is to present a novel implementation of …

Democracy in Constituent Moments: Exploring the Spanish Constitutional Debate of 1931 through Political Theory and Conceptual History
2019
This paper aims to answer the question of why constituent moments are relevant to political theory. It hypothesises the Spanish constitutional debate of 1931 as a case of conceptual innovation in parliamentary politics by arguing that debates in constituent moments entail a special kind of parliamentary argumentation when new political regimes are established. There, all sorts of theoretical, normative, historical, and institutional aspects are discussed to deliberate on the future character and functioning of a political regime. From a methodological point of view, this analysis draws on the revision of arguments and political terms used by MPs during the Spanish constituent assembly of 19…
Más allá de Marx: postobrerismo y posmarxismo. Una revisión de los fundamentos teóricos de la multitud y el pueblo
2018
The article is a synthetic essay that exposes the main theoretical lines of the postmarxist approach of Laclau and Mouffe, on the one hand, and the autonomist post-operaism of Negri, Hardt, Virno, etc., on the other hand. These theories are conceived as attempts to rationalize current political bets by various political sectors and social movements. It analyzes both argumentative strategies from «orthodox» Marxism and the structure / superstructure relationship; and the forms of constitution of new subjectivities. It compares the theoretical fundamentals of hegemonic articulations and counter-power experiences. It discusses, likewise, the scope and limitations of the categories of «people» …
Trabajo y TIC en los mayores de 45 años. Un análisis de la introducción al ciberespacio desde la esfera laboral
2018
The inequality in access to cyberspace due to age at the beginning of the twenty-first century was followed by an economic crisis that intensified many socio-labor dynamics. Through a contextualization with INE data and a qualitative sample, the following work tries to capture the attitudes about ICT related to their previous labor trajectories on those over 45 years of age; and, on the other hand, its introduction to cyberspace from work as a conditioner in the perception of crisis, the maintenance of employment or their way out to retirement.
