La organización del Taller de Estudio Asistido (TEA) como recurso educativo para lograr una Educación de calidad
2008
El Taller de Estudio Asistido (TEA) tiene como objetivo general instaurar hábitos de trabajo y organización a través de las tareas escolares. Sirve de refuerzo, orientación y apoyo al alumnado del centro -tanto de educación Primaria como de Secundaria- que por motivos socioculturales tienen dificultades para seguir el Currículum prescrito así como para desarrollar las tareas realizadas en la dinámica de clase. A través del diseño del TEA pretendemos garantizar la atención a los colectivos más vulnerables para mejorar su formación y prevenir los riesgos de exclusión social. Se trata de lograr el acceso a una educación de calidad para todos/as y paliar las necesidades del alumnado asociadas a…
¿Life coachers? Padres de alumnos y trabajo de apoyo a la construcción biográfica de los hijos
2018
The obligation to attend school for a longer period transformed schooling into a narrative pivot of youth biographies and an inescapable element of the individuation process. In Portugal, at the entrance to the secondary school, young adolescents are invited to formulate a career choice among a set of options offered by the educational institution. This choice, strongly anchored to the exercise of individual autonomy and ideally involving the individual in a life project, constitutes a true biographic challenge. Either because the «field of possibilities» depends largely on the academic value demonstrated throughout the school trajectory; either because the prevailing context of uncertainty…
La transición a la sostenibilidad como objetivo urgente para la superación de la crisis sistémica actual
2016
Este trabajo pretende contribuir a cuestionar la creencia, ampliamente extendida entre la ciudadanía, los responsables políticos, e incluso entre los educadores, de que la transición a la Sostenibilidad es un objetivo para el futuro, que puede esperar ante las necesidades urgentes del presente. Se intenta mostrar que, por el contrario, dicha transición es necesaria ahora para dar solución a graves problemas interconectados, que amenazan ya seriamente a la presente generación, como el cambio climático, la pérdida de biodiversidad, el agotamiento de recursos fundamentales, o la pobreza y el desempleo masivo que destruyen la cohesión social. Se puede de este modo dar respuesta hoy a las necesi…
The professional agency of teacher educators amid academic discourses
2012
Agency has been seen as fundamental in the renegotiation of professional identities. However, it is unclear how teacher educators exercise their professional agency in their work, and how multiple discourses frame and restrict the practice of their professional agency. This study examines how teacher educators practise agency in negotiating their professional identities amid the multiple discourses emerging from the academic context of their work. The aim was to investigate educators’ locally expressed professional agency in the context of the more global discourses that may construct teacher educator identities. The analysis made use of applied thematic discursive analysis to address patte…
L’Effet Hamlet: une dégénérescence transformationnelle?
2022
Max a enfermé Tom dans la cave does not specify whether Tom was in the cellar before being locked up or not. This article shows how this semantic indeterminacy, highlighted and called Effet Hamlet by Jean-Paul Boons in the late seventies, should perhaps be considered a fall-out of syn- tactic transformational processes.
Inclusive pion-nucleus double charge exchange.
1989
Inclusive double charge exchange reaction is studied by using a model which combines a microscopic many-body calculation of reaction probabilities with a Monte Carlo simulation procedure. Comparison with present experimental results requires that the (\ensuremath{\pi},2\ensuremath{\pi}) reaction be included and a proper evaluation of this latter reaction is also done. The combined results compare favorably with experiment, giving extra support to this model of the pion-nucleus interaction which was previously shown to provide a good description of all other inclusive reactions and elastic scattering.
A PROJECT-POSED APPROACH TO REAL BODY DYNAMICS: THE ROLE OF CONSTRAINTS IN ELASTIC WAVE PROPAGATION
2010
In this paper we present some results of a project-posed approach to the teaching of mechanical wave propagation focused on observations and measurements of wave properties in solids and on modelling of these properties by using different simulation tools. In particular, the propagation speed of sound waves in metallic rods is studied by using simple experimental arrangements based on the measurements of contact times between a small body and long metallic rods with which the body can collide. An interesting effect of this approach is the revision of students’ ideas about the rigid body model, studied at high school or college level and usually hardly followed by deepening on the fundamenta…
Convenzione europea dei diritti umani e problemi di costituzionalità della legge elettorale italiana
2013
By an order of 21 March 2013, the Court of Cassation referred to the Constitutional Court the question of constitutionality of the current Italian electoral law on the grounds that it runs counter to the constitutional principles of free and equal suffrage. The Constitutional Court has been called by the referring judge to focus on three main aspects of law: the closed list system; the majority bonus in the Chamber of Deputies, by which the coalition that wins the highest number of votes receives at least 55% of the seats; and the majority bonus in the Senate, which is assigned on a regional level. While the Court of Cassation affirmed that the constitutional principles on the right to vote…
Energy management strategy to reduce pollutant emissions during the catalyst light-off of parallel hybrid vehicles
2020
Abstract The transportation sector is a major contributor to both air pollution and greenhouse gas emissions. Hybrid electric vehicles can reduce fuel consumption and CO2 emissions by optimizing the energy management of the powertrain. The purpose of this study is to examine the trade-off between regulated pollutant emissions and hybrid powertrain efficiency. The thermal dynamics of the three-way catalyst are taken into account in order to optimize the light-off. Experimental campaigns are conducted on a spark-ignition engine to introduce simplified models for emissions, exhaust gas temperature, catalyst heat transfers and efficiency. These models are used to determine the optimal distribut…
A novel linear-non-linear digital control for DC/DC converters
2006
In this paper, a digitally controlled multi-module DC-DC converter with fast transient response, based on a linear-non-linear control is presented. The proposed digital control improves the stability of the system, cuts off the effects of limit-cycle and reduces the recovery time, by making the "effective" bandwidth of the system independent of the bandwidth of the linear control loop and limits, at the same time, output voltage variations. The novel digital control is AVP-compatible and halves the recovery time. Preliminary hardware tests on a single phase step-down converter are reported. The experimental results match simulation ones, obtained by modelling system with Matlab/Aldec mixed …
