Videojuegos para el desarrollo del pensamiento crítico y el diálogo
2020
El presente artículo retoma los resultados de la investigación realizada por la autora, cuyo título es Videojuegos en el aula: una propuesta asociada al desarrollo del pensamiento crítico (2016). Las inquietudes generadas en el estudio guardan relación con los lineamientos para desarrollar una propuesta de uso de los videojuegos en el aula, asociada al desarrollo del pensamiento crítico, en un grupo de jóvenes venezolanos escolarizados con edades comprendidas entre 13 y 17 años. Se procuró entender el videojuego como producto cultural en el contexto venezolano, los hábitos de consumo por parte de los sujetos estudiados y su relación con el pensamiento crítico y el desarrollo de procesos de …
Convergence of inertial prox-penalization and inertial forward-backward algorithms for solving bilevel monotone equilibrium problems
2023
The main focus of this paper is on bilevel optimization on Hilbert spaces involving two monotone equilibrium bifunctions. We present a new achievement consisting on the introduction of inertial methods for solving this type of problems. Indeed, two several inertial type methods are suggested: a proximal algorithm and a forwardbackward one. Under suitable conditions and without any restrictive assumption on the trajectories, the weak and strong convergence of the sequence generated by the both iterative methods are established. Two particular cases illustrating the proposed methods are thereafter discussed with respect to hierarchical minimization problems and equilibrium problems under a sa…
Weak and strong convergence of an inertial proximal method for solving bilevel monotone equilibrium problems
2022
In this paper, we introduce an inertial proximal method for solving a bilevel problem involving two monotone equilibrium bifunctions in Hilbert spaces. Under suitable conditions and without any restrictive assumption on the trajectories, the weak and strong convergence of the sequence generated by the iterative method are established. Two particular cases illustrating the proposed method are thereafter discussed with respect to hierarchical minimization problems and equilibrium problems under saddle point constraint. Furthermore, a numerical example is given to demonstrate the implementability of our algorithm. The algorithm and its convergence results improve and develop previous results i…
Zone of Proximal Development (ZPD) as an Emergent System: A Dynamic Systems Theory Perspective
2016
This paper sets out to present a novel construal of one of the notions of Vygotskian cultural-historical theory viz., zone of proximal development (ZPD) drawing upon dynamic systems theory. The principal thesis maintains that ZDP is an emergent and dynamic system which is engendered by a dialectical concatenation of psychogenesic and sociogenesic facets of human development over time. It is reasoned that Vygotskian cultural-historical theory of human development, by invoking dialectical logic, has transcended Cartesian substance dualism and in turn has proffered a monistic and process-anchored ontology for emerging becoming of human consciousness. Likewise, it is contended that dynamic syst…

Plenary conference: Keys to successful physical activity during childhood
2014
Introduction Based on different theories of dynamic systems, children's development occurs through interaction between their genes, their physical and socio-emotional environment, and the amount and quality of earlier experiences. The amount of physical activity (PA) has been recognized as one very important mediator in supporting young children's physical growth and overall development. Moreover, PA has been shown to effect children's daily well-being and health [1] . Children are physically active through their play. When children engage in physically active play, they use their whole body with all their senses and large muscles. Through playing children learn to feel their body, recogniz…
L'imagerie multispectrale embarquée pour caractériser la croissance et l'état sanitaire du feuillage de la vigne
2015
Multispectral imaging systems are widely used in remote sensing and applied to viticulture context for the canopy characterization. This technique is not used in proximal sensing, to characterize vineyard foliage. Yet the results of field tests led in fixed position have revealed its capacity to estimate the leaf area. The aim of this project is to assess the suitable of a multispectral imaging system as an embedded sensor for vine foliage characterization. To this end, a multispectral camera acquiring visible and near-infrared images and a Greenseeker RT-100 apparatus providing an NDVI (Normalized Difference Vegetation Index), were installed on a track laying tractor. It was equipped with …
Convergence rate of a relaxed inertial proximal algorithm for convex minimization
2018
International audience; In a Hilbert space setting, the authors recently introduced a general class of relaxed inertial proximal algorithms that aim to solve monotone inclusions. In this paper, we specialize this study in the case of non-smooth convex minimization problems. We obtain convergence rates for values which have similarities with the results based on the Nesterov accelerated gradient method. The joint adjustment of inertia, relaxation and proximal terms plays a central role. In doing so, we highlight inertial proximal algorithms that converge for general monotone inclusions, and which, in the case of convex minimization, give fast convergence rates of values in the worst case.
Adaptative memory and animacy effect
2017
According to the adaptive memory view, human memory was shaped in the distant past to remember fitness relevant information (e.g., finding food, protecting ourselves from predators). An increasing number of studies favor this view, by showing that information related to to survival is memorized better than information not related to survival (Nairne, Thompson, & Pandeirada, 2007). Recently, a new type of findings further supports this functional approach of memory: animacy effects, that is to say the observation that animates (living things able of independent movements; e.g., baby, grasshopper) are remembered better than inanimates (non-living things e.g., teakettle, rope). One account of …
