Initiation of deep convection at marginal instability in an ensemble of mesoscale models: a case-study from COPS

2011

The present study investigates the initiation of precipitating deep convection in an ensemble of convection-resolving mesoscale models. Results of eight different model runs from five non-hydrostatic models are compared for a case of the Convective and Orographically-induced Precipitation Study (COPS). An isolated convective cell initiated east of the Black Forest crest in southwest Germany, although convective available potential energy was only moderate and convective inhibition was high. Measurements revealed that, due to the absence of synoptic forcing, convection was initiated by local processes related to the orography. In particular, the lifting by low-level convergence in the planet…

Magnetic particle mixing with magnetic micro-convection for microfluidics

2015

International audience; In this paper we discuss the magnetic micro-convection phenomenon as a tool for mixing enhancement in microfluidics systems in cases when one of the mis-cible fluids is a magnetic particle colloid. A system of a water-based magnetic fluid and water is investigated experimentally under homogeneous magnetic field in a Hele-Shaw cell. Subsequent image analysis both qualitatively and quan-titatively reveals the high enhancement of mixing efficiency provided by this method. The mixing efficiency dependence on the magnetic field and the phys-ical limits is discussed. A suitable model for a continuous-flow microfluidics setup for mixing with magnetic micro-convection is als…

Addressing informality, gender and ethnicity in domestic labour

2014

The legal framework concerning household employment has undergone a number of changes worldwide. The 100th International Labour Conference in June 2011 was highly significant as it adopted the first international labour standards specifically for domestic workers: Convention No. 189 and the supplementing Recommendation No. 201. This article analyses recent Spanish reforms (2011–2013) in order to assess the effects of these changes, taking into account the characteristics of domestic work: feminized, informal, ethnicized and vulnerable. Although aimed at improving employment and working conditions, the new Spanish legislation has resulted in a number of setbacks as well as some progress. The…

A comparative study of partitioning methods for crowd simulations

2010

The simulation of large crowds of autonomous agents with realistic behavior is still a challenge for several computer research communities. In order to handle large crowds, some scalable architectures have been proposed. Nevertheless, the effective use of distributed systems requires the use of partitioning methods that can properly distribute the workload generated by agents among the existing distributed resources. In this paper, we analyze the use of irregular shape regions (convex hulls) for solving the partitioning problem. We have compared a partitioning method based on convex hulls with two techniques that use rectangular regions. The performance evaluation results show that the conv…

Propuestas de intervención educativa para mejorar la convivencia. Una experiencia en Formación Profesional

2013

Desde el diseño de tareas y el análisis de nuestra práctica docente asumimos que la convivencia implica comunicación, empatía, comprensión, aceptación del otro. El aula es un espacio complejo donde converge alumnado con diferencias sociales, étnicas y culturales. Es importante gestionar esa diversidad para propiciar un clima en el aula y en el centro que posibilite el generar contextos de aprendizaje que faciliten el intercambio de saberes y la construcción del conocimiento. La convivencia es un elemento fundamental en el proceso de aprendizaje porque supone hablar del entorno social, cultural y afectivo en el que vivimos y además, porque aprender a convivir es fundamental para el desarroll…

The Patras blended strategy model for deep and meaningful learning in quality life-long distance education

2019

Life‑long learning is currently being embraced as a central process that could disrupt traditional educational paths. Apparently, the (ideal) type of learning often promoted is deep and meaningful learning, though it is not always required to be so. Deep learning goes beyond superficial knowledge assimilation of unlinked facts; it aims at developing deep disciplinary understanding, transformative knowledge, personal meaning, emotional intelligence, critical thinking, creativity and metacognitive skills. Meaningful learning occurs when learning is active, constructive, intentional, authentic, and cooperative. Technology enhanced teaching and learning methods should prove their potential to t…

Finnish pre-service teachers’ perceptions of their strategic learning skills and collaboration dispositions

2019

To support the development of pupils’ 21st-century skills, teachers themselves must also be competent in these skills and learn them during pre-service teacher education. The aim of this study is to investigate what kind of profiles emerge among Finnish first-year pre-service teachers’ (N = 872) in terms of perceptions of their strategic learning skills and collaboration dispositions and what background variables explain membership of the profiles found. Latent profile analysis showed five student profiles corresponding to perceived strategic learning skills and collaboration dispositions. The most robust factor explaining the membership of the profiles was life satisfaction. Pre-service te…

Students’ accounts of their participation in an intensive long-term learning community

2005

Collaborative learning environments have been analysed extensively, yet we know relatively little about how students experience their participation in long-term learning communities where learners work together over extended periods of time. This study aims to understand pre-service teacher–students’ experiences and accounts of their participation in a university-based long-term learning community. The study investigates issues of change and stability, with respect to the students’ perceptions of participation over the first 2 years of their work within the learning community. The study also addresses the relations between the students’ accounts of participation and their learning experienc…
