Emergence, perspective et mise à l'épreuve contemporaine du constructivisme sexué
2009
Dans une approche constructiviste, nous nous attacherons ici a presenter dans un souci epistemologique les concepts de sexe et de genre, les perspectives essentialiste puis constructiviste des etudes sur les rapports sociaux de sexe, et enfin, nous questionnerons la portee symbolique d’un positionnement constructiviste a tendance radicale, a une epoque – et un espace – ou les valeurs dites « feminines » sont plutot malmenees (Dufour, 2007 ; Nots, 2008) voire en peril (Kahn, 2007).
Le sport comme espace de construction sociale de la féminité : jugements d'adolescentes et d'adolescents concernant les filles qui pratiquent des spo…
2006
International audience; L'état des connaissances actuelles en sociologie du sport permet d'affirmer sans hésitation que les pratiques d'activité physique et sportive sont des pratiques sociales et culturelles (voir, entre autres, le numéro de Recherches féministes sur la question (vol. 17, no 1, 2004)). En ce sens, elles véhiculent des normes, sont le site de débats idéologiques et participent à la construction de rapports sociaux, dont les rapports sociaux de sexe. On a pu voir à travers l'histoire du sport que cette institution véhicule les normes sociales dominantes de la masculinité et de la féminité et, en conséquence, qu'elle participe à leur reproduction (Hargreaves 1994; Louveau 198…
Numerical vibroacoustic analysis of plates with constrained-layer damping patches
2011
International audience; A numerical vibroacoustic model that can manage multilayered plates locally covered with damping patches is presented. All the layers can have an on-axis orthotropic viscoelastic behavior. Continuity of displacements and transverse shear stresses at each interface is enforced, which permits to write the entire displacement field in function of the displacements of the-common-first layer, leading to a two-dimensional plate model. The problem is then discretized by Rayleigh-Ritz's method using a trigonometric basis that includes both sine and cosine functions in order to treat various boundary conditions. The excitation can be of mechanical kind (concentrated or distri…
A holistic perspective on the theoretical foundations for ICT4D research
2018
While many theories have guided research Information and Communication Technologies for Development (ICT4D), we are yet to construct a clear and coherent narrative that would help us answer the question of how ICT fosters development in underdeveloped communities. In this paper, we argue that one of the main reasons for this is that our holistic understanding of ICT4D is seldom grounded in theories to understand the core areas that define the field, namely, ICT, Development, and, ‘4’ which are the transformative processes that link the two. Through a brief literature review, we list theories that have informed ICT4D research in each of these areas. We present examples of theories, namely, C…
Kuka minä olen? Monikulttuuristen opiskelijoiden identiteettipuhetta
2008
Young people with immigrant backgrounds follow different paths to acculturate. Some integrate into the new society so that they cannot be singled out from the majority; others maintain their ethnic culture in addition to adopting values of the larger society. Alternatively, some immigrant youth distance themselves from both their parents' culture and new one. The challenge for second generation immigrants is that they have to make a double transition to adulthood. Immigrant adolescents develop an identity as members of their own group, and to varying degrees, as members of the lager society. Because of the variety of influences and opportunities they face in making choices on these issues, …
Factor Structure and Measurement Invariance of the Spanish Burnout Inventory Among Professionals Across 17 Countries and Regions
2022
AbstractStudies on the prevalence of burnout in professionals in service organizations who work in direct contact with the clients or users of the organization have concluded that burnout is a serious health disorder that has increased due to the COVID-19 pandemic. A significant advantage of the Spanish Burnout Inventory (SBI) over other instruments is that it provides a broader conceptualization of burnout by including feelings of guilt as a dimension of burnout to explain its development. However, the measurement invariance of the SBI across countries has not been investigated. The purpose of this study was to test the measurement invariance of the SBI among professionals across 17 countr…
Effect of Organic Fertilizers on Avocado Trees (Cvs. Fuerte, Hass, Lamb Hass) in Western Crete, a Cool Subtropical Region
2022
The market for avocado is one of the fastest expanding worldwide, inclduing the Mediterranean basin. Organic farming systems cannot make use of synthetic fertilizers and therefore rely on several cultural techniques to maintain vigorous young trees and for quick shoot development, satisfactory yield, and fruit quality. We studied the effect of three different organic products (Terra Insecta® (Aeiphoria-Sustainable products of Crete, Chania, Greece), Fruit-Fix®, and AMINO-16® (both products manufactured by EVYP, Sindos, Thessaloniki, Greece) on avocado plants in the cool subtropical area of southern Greece. Three experiments were carried out, two of them on young avocado trees, a…

The effects of biomass co-gasification and co-firing on the development of combustion dynamics
2018
Abstract Effects of wheat straw co-firing with gas (propane flame) and co-gasification/co-combustion with wood pellets on the development of thermo-chemical conversion of biomass pellets and on heat energy production were experimentally studied and analyzed with the aim to improve the gasification/combustion characteristics and the applicability of wheat straw as an alternative energy source for cleaner heat energy production. The results suggest that the wheat straw co-firing with propane provides an enhanced thermal decomposition of pellets with more complete combustion of volatiles increasing thus the heat output at thermo-chemical conversion of wheat straw and the produced heat energy p…
Didáctica de las ciencias experimentales y sociales
1993
Presenta un ejemplo concreto de tratamiento de situación problemática abierta con una orientación investigativa. Plantea una reflexión previa acerca del interés de la situación problemática como forma de favorecer una actitud más positiva de los alumnos y de romper con actitudes puramente escolares de 'seguimiento de consignas'. El tipo de enunciado propuesto: ¿atravesamos la calle o nos esperamos?, ha permitido enfrentar a los alumnos con la tarea de precisar cual es la magnitud a determinar, ampliando así la toma de decisiones que el paso de una situación problemática conlleva. Otra singularidad de interés es la que representa una resolución en términos de desigualdad a lo que los alumnos…
