Agroecological engineering
2015
Earth has recently entered the new era of the Anthropocene, during which the rise of human activities are impacting for the first time ecosystems and climate on the global scale. Since the 1960s the green revolution has improved food production in quantity using industrially-designed agriculture, which has led to global pollution by pesticides and losses of food quality, biodiversity and soil carbon. As a consequence there is a need to implement agroecological practices in order to produce food safely and in a sustainable way. This virtual issue presents principles and applications of agroecological engineering, exemplified in 19 selected review articles from the journal Agronomy for Sustai…
Intervención terapéutica y coordinación familiar en los inicios comunicativos de un caso de atención temprana
2020
En este estudio de caso se aborda la intervención realizada en un centro de diagnóstico y atención temprana, a una alumna de dos años con hemiparesia lateral izquierda y dificultades en la manipulación y comunicación. Aplicando a lo largo de cuatro meses el sistema de Comunicación Total de Benson Schaeffer con el apoyo del método TEACCH, se pretende superar las graves limitaciones comunicativas de la alumna. El procedimiento metodológico utilizado es mixto y las técnicas de investigación empleadas son la aplicación de un test estandarizado, la entrevista, los registros de observación y el análisis documental. A partir del test cumplimentado por la madre que establece la evaluación inicial d…
Instanton Counting, Quantum Geometry and Algebra
2020
The aim of this memoir for "Habilitation \`a Diriger des Recherches" is to present quantum geometric and algebraic aspects of supersymmetric gauge theory, which emerge from non-perturbative nature of the vacuum structure induced by instantons. We start with a brief summary of the equivariant localization of the instanton moduli space, and show how to obtain the instanton partition function and its generalization to quiver gauge theory and supergroup gauge theory in three ways: the equivariant index formula, the contour integral formula, and the combinatorial formula. We then explore the geometric description of $\mathcal{N} = 2$ gauge theory based on Seiberg-Witten geometry together with it…
Le meilleur compromis pour tous
2007
07018; L'hétérogénéité du public d'élèves rend-elle les contextes d'apprentissage moins efficaces ? Pour alimenter la réflexion sur ce sujet, l'auteur rappelle quelques résultats majeurs de la recherche en éducation sur cette question à plusieurs niveaux d'analyse : les systèmes éducatifs (de façon globale), les pratiques de constitution de classes dans les établissements scolaires (classes de niveau éventuellement), et les organisations pédagogiques au sein même de la classe (ability grouping).
Worldwide Diffusion of ISO 14001 Standard
2008
We conduct an empirical examination of national conditions that promote the diffusion of the ISO 14001 standard. Our estimates confirm earlier studies on several determinants. While environmental considerations are important in the diffusion of the ISO 14001 standard, we show that other factors play a significant role as well, such as the prior diffusion of ISO 9000 and the country’s education level. Our main contribution is to provide empirical evidence for the hypothesis that the participation of a country or an economic sector in the standard-setting process is a major driver of its future adoption of the standard.
Identifier et évaluer les compétences dans le système éducatif : quels apports pour la recherche en education ?
2007
07077 - 176 p.; Après un bref rappel sur la fonction de production scolaire, nous nous attacherons à montrer l'intérêt de mieux en spécifier les résultats, en termes de compétences développées par les élèves notamment. Nous reviendrons, pour cela, sur la recherche d'une éventuelle définition de la notion de compétence, pour s'attarder plus particulièrement sur les mesures de la compétence proposées par les acteurs du système à différents niveaux : local, national ou international (chapitre I). Ceci nous amènera à mettre en parallèle, d'un point de vue méthodologique, les outils dont dispose le praticien avec ceux mis à la disposition du chercheur, qui s'avèrent peut-être plus complets, mais…
A multilight approach for documenting and modeling the appearance of large cultural heritage objects
2022
In recent years, Computer Vision has played a major role in the investigation of sur-face appearance, particularly with the introduction of image-based rendering algorithms. Reflectance transformation Imaging (RTI) is one of these approaches. The RTI is a multi-light imaging technique that involves taking a series of images of an item using a stationary camera, while the location of the incident light varies in each photograph. Thanks to the information gathered from this type of acquisition, which is also defined as a Multi-light Image Collection (MLIC), it is possible to model the angular reflectance of a surface. The RTI is frequently employed in the documentation and study of architectu…
Valutare l'equità dei sistemi scolastici
2006
06038; Denis Meuret spiega le ragioni a sostegno di una misura del grado diquità dei sistemi scolastici e presenta i principi basilari per costruire un insieme d'indicatori dell'equità dell'istruzione e della scuola. Da questi principi è partito il GERESE (Il Gruppo Europeo di Ricerca sulla Equità dei Sistemi Educativi) per comporre l'insieme di 29 indicatori dell'equità. Meuret illustra al termine del suo saggio la structtura e l'organizzazione di questo insieme che è senza dubbio uno dei prodotti recenti più originali della ricerca sulla giustizia educativa

Economic crisis and educational crisis : looking ahead
1986
The worldwide economic crisis has now been with us for a good ten years and, for many countries, the end of the tunnel is not yet in sight and is probably a long way off. So what kind of crisis is this, that can continue for so long, given the fact that, etymologically, the term denotes a brief, crucial moment when the outcome of a troubled situation is decided, for better or for worse? Infelicitous as the term commonly used to describe the present state of the world economy may be, it is none the less true that what is designated as a crisis encompasses a historical phase in which economic growth is lower than in the preceding phase and the problems bound up with certain economic trends (i…
