Educación XX1 : revista de la Facultad de Educación

2019

Los avances tecnológicos han provocado que el ámbito de la educación se vea influenciado por la aparición de nuevos modelos de enseñanza y aprendizaje mediados por la gran cantidad de recursos digitales y dispositivos electrónicos que cuenta hoy el profesorado. Uno de los enfoques metodológicos que está emergiendo como consecuencia de la innovación educativa es el flipped learning. Este modelo de enseñanza y aprendizaje se sustenta en la idea de que los discentes puedan visualizar y trabajar los contenidos de las próximas sesiones presenciales en el aula fuera del entorno académico, con la finalidad de dedicar el mayor tiempo posible en clase a la resolución de problemas y al despliegue de …

Preliminary results of a multi-scale structural analisys in an analogue carbonate reservoir (Hyblean Plateau, Sicily, Italy)

2010

With the aim of studying the multi-scale fault architecture and permeability in hydrocarbon-rich porous carbonate rocks, we are currently involved in a project focused on the structural analysis of fractured and faulted platform-to-ramp carbonates cropping out in the Hyblean Plateau (Sicily, Italy). The Hyblean Plateau is part of the Maghrebian foreland and forms the northern portion of the African plate. The plateau is a NE-oriented structural high crosscut by a large-scale N10°-20°E oriented strike-slip fault system, named Scicli-Ragusa, which was affected by right-lateral kinematics during the Upper Miocene-Lower Pliocene. Some authors documented a recent activity of the Scicli-Ragusa fa…

The thermal performances of historic masonry: In-situ measurements of thermal conductance on calcarenite stone walls in Palermo

2018

Abstract Rich literature explores materials and construction techniques of historic buildings, but limited information is available about the thermal and hygrometric features of their envelope. Nevertheless, accurate hygrothermal data are essential for identifying effective energy upgrade measures, which must be compatible with the conservation of the architectural heritage. In order to fill this gap, it is necessary to refer to local contexts, where the variety of historic buildings is limited and their material and construction features are comparable. This paper focuses on historic masonry walls and discusses the results of twenty in-situ measurements of thermal conductance, performed al…

The (im)possible success of disadvantaged students. Reflections on education, migration and social change

2019

The paper focuses on the ?unexpected pathways? of successful students with an immigrant background: these biographical routes, that seems socially impossible, raise theoretical issues around the individual-society, actor-structure relationship. Disadvantaged students who succeed represent a sociological challenge in the attempt to understand atypical situations and to identify the institutional processes and the structural opportunities that facilitate them, reducing ethnic inequalities in education. This framework is the starting point of the Su.Per. project (Success in educational pathways of students with immigrant background), based on the collection of written autobiographies of 65 imm…

Evaluation of web reinforcements in prestressed concrete box girders through shear-transverse bending domains

2020

In concrete box girders, the amount and distribution of reinforcements in the webs have to be estimated considering the local effects due to eccentric external loads and cross-sectional distortion and not only the global effect due to the resultant forces of a longitudinal analysis: shear, torsion and bending. This work presents an analytical model that allows designers to take into account the interaction of all these effects, global and local, for the determination of the reinforcements. The model is based on the theory of stress fields and it has been compared to a 3D finite element analysis, in order to validate the interaction domains. The results show how the proposed analytical mode…

Fractional viscoelastic transversally isotropic Timoshenko beam

2014

In this paper the viscoelastic behavior of pultruded beams has been examined. Pultruded beams are constituted by a polymer infilled with reinforcement in longitudinal direction, while in the orthogonal direction no fiber are present for technological reasons. As a consequence the material has two different behaviors in longitudinal and in orthogonal directions. It follows that pultruded beams are transversally isotropic, and the shear deformation may not be neglected. Based upon the previous observations and assuming for Creep and/or Relaxation test the power law, the constitutive equations are ruled by fractional operators. From constitutive laws, and assuming the Timoshenko beam theory to…

Current L2 self-concept of Finnish comprehensive school students : The role of grades, parents, peers, and society

2021

L2 (second/foreign language) motivation research in Finland has been scarce. Furthermore, international motivational research has focused more on ideal and ought-to selves, leaving the current L2 self-concept in the background. In the present study, we attempted to address this gap, exploring what shapes L1 (mother tongue) Finnish students' understanding of themselves as users and learners of L2s. Using structural equation modelling, we studied the relationships between students' (n = 1206) current L2 self-concept and parental encouragement, peer pressure, societal expectations, and grades. We further studied which of these factors are the best predictors of students' current L2 self-concep…

Imagined Identities and Communities in the Learning Context of Finnish as a Second Language

2022

This case study on two migrant pupils of Finnish as L2 was carried out in Finland, which lies outside the most common context of such research, i.e. ESL or EFL in an English-speaking country. The study thus attempts to address the need to expand the research contexts of L2 identity issues. Using ethnographic data collected inside and outside a preparatory language classroom, this study aims to examine how the pupils make sense of their new learning environment and how, through language learning, they construct identities. The results show that they extend their repertoire of identities and connect to a wider world of possibilities as they strive to gain greater resources in their imagined c…

Service Climate and Display of Employees’ Positive Emotions: The Mediating Role of Burnout and Engagement in Services

2011

This article aims to test a model linking service climate to the frequency of expression of positive emotions by frontline employees. We propose that burnout and engagement at work mediate the relationship between service climate and the expression of positive emotions. Service climate impacts negatively on burnout and positively on engagement; in turn, burnout and engagement are significantly related to the frequency of expression of positive emotions. This model was tested both at the individual and work-unit levels. In addition, it was compared with a direct model that proposes an additional direct link from service climate to frontline employees’ positive emotions. Models were tested th…
