ANÁLISIS DE LA DIVERSIDAD EN MATERIALES DIDÁCTICOS DE EDUCACIÓN PRIMARIA
2021
El objetivo de este análisis fue detectar la presencia o no de la diversidad en las imágenes de materiales didácticos realizando un estudio de tipo descriptivo y comparativo entre los diferentes materiales. La muestra recogió 66 materiales didácticos. Los resultados obtenidos mostraron que las parejas homosexuales son excluidas de las imágenes y que se proyecta una visión estereotipada tanto de la discapacidad como de la etnia llegando a la discriminación de alguna de ellas. Es por ello por lo que consideramos la necesidad de concienciar sobre la importancia de las imágenes de los materiales didácticos y, de esta manera, identificar y eliminar los estereotipos que se están transmitiendo.

Deducing the stage-discharge relationship for contracted weirs by the outflow theory of Malcherek
2019
The aim of this paper was the deduction of a new stage-discharge relationship for a contracted weir, having a crest length less than the channel width, by using the Malcherek’s outflow theory. The average outflow velocity over the rectangular contracted weir was expressed in terms of the head over weir, the momentum correction coefficient and the ratio between the crest length and the channel width. This theoretically deduced stage-discharge formula was calibrated by measurements carried out for values of the ratio between the crest length and the channel width ranging from 0.3125 to 0.9375. In particular, a relationship to estimate the momentum correction coefficient for contracted weirs w…
The Origin of Non-thermal Fluctuations in Multiphase Flow in Porous Media
2021
Core flooding experiments to determine multiphase flow in properties of rock such as relative permeability can show significant fluctuations in terms of pressure, saturation, and electrical conductivity. That is typically not considered in the Darcy scale interpretation but treated as noise. However, in recent years, flow regimes that exhibit spatio-temporal variations in pore scale occupancy related to fluid phase pressure changes have been identified. They are associated with topological changes in the fluid configurations caused by pore-scale instabilities such as snap-off. The common understanding of Darcy-scale flow regimes is that pore-scale phenomena and their signature should have a…
Mechanical Coupling Between Muscle-Tendon Units Reduces Peak Stresses
2017
The presence of mechanical linkages between synergistic muscles and their common tendons may distribute forces among the involved structures. We review studies, using humans and other animals, examining muscle and tendon interactions and discuss the hypothesis that connections between muscle bellies and within tendons may serve as a mechanism to distribute forces and mitigate peak stresses. peerReviewed
Divided Wall Column Modeling and Simulation in an Open-Source Environment
2020
The divided wall column (DWC) can achieve sharp separations of three or more components in a single shell, substituting conventional sequences of two or more binary distillation columns, with lower expenses. Despite these advantages, DWC models are not available in commercial chemical process simulators. To simulate DWC, users must employ instances of conventional column model and couple them in different configurations. In this paper, a DWC model was developed in EMSO (Environment for Modeling, Simulation and Optimization). DWC model was then used for simulating the separation of an equimolar mixture of three hydrocarbons. Results show that, depending on the number of trays, DWC presented …
Dynamics and extraction of quantum discord in a multipartite open system
2011
We consider a multipartite system consisting of two noninteracting qubits each embedded in a single-mode leaky cavity, in turn connected to an external bosonic reservoir. Initially, we take the two qubits in an entangled state while the cavities and the reservoirs have zero photons. We investigate, in this six-partite quantum system, the transfer of quantum discord from the qubits to the cavities and reservoirs. We show that this transfer occurs also when the cavities are not entangled. Moreover, we discuss how quantum discord can be extracted from the cavities and transferred to distant systems by traveling leaking photons, using the input-output theory.

Les TIC en la formació lingüística inicial de mestres
2013
L’ús de les TIC en la formació lingüística inicial de mestres facilita la interacció entre professorat i alumnat, resulta motivador i afavoreix el desenvolupament de la competència comunicativa i digital. A través d’un seminari adreçat a l’alumnat de primer curs del Grau de Mestre/a, hem seleccionat recursos electrònics per a l’elaboració i la presentació de treballs acadèmics; i també hem dut a terme l’aplicació didàctica d’eines TIC mitjançant la utilització d’un wiki i d’una xarxa social privada per a treballar amb el grup-classe. The usage of ICT in teachers’ initial linguistic training makes the interaction between teachers and students easier. It is motivating and facilitates the comm…
A Mission Impossible? Learning the Logic of Space with Impossible Figures in Experience-Based Mathematics Education
2016
Most visual effects based on mathematically and physically describable phenomena and formalizable processes. Creating visual illusions, paradox structures and ‘impossible’ figures through playful and artistic procedures, holds an exciting pedagogical opportunity for raising students’ interest towards mathematics and natural sciences and technical aspects of visual arts. The Experience Workshop Math-Art Movement has a number of pedagogical methods, which are connected to visual paradoxes and perspective illusions. In the first part of our article, we introduce classroom exercises connected to the Hungarian artist Tamás F. Farkas’s paradox structures and impossible figures. There are certain …
Investigation into the impact of training on elementary teachers? ability to use them
2015
This study presents the findings from a controlled trial of the new Teacher Guides for English as a subject (n=293) that form part of the new elementary English Standards-Based Curriculum in Papua New Guinea. The aim was to investigate whether training on the Teacher Guides had an impact on teachers’ ability to use and deliver the scripted lessons they contain. The trial was conducted in two provinces. Assessment was by pre- and post-trial questionnaires, reflective journals and focus groups. The multi-arm trial ran over seven weeks with three training groups: group 1, with 1.5 days of full training (n=96), group 2, with 0.5 day of introductory training (n=100), and group 3, (n=97) with no …
