Les pratiques pédagogiques des enseignants universitaires :

2012

In France, some studies (Boyer & Coridian, 2002; Clanet, 2001) have highlighted the heterogeneity of teaching practices at the university, especially in the first year, but don't analyze accurately the effects of this variety on the students. However, these practices are not without consequences for them (Bireaud 1990; Bellat Duru, 1995; Galinon Menelec, 1996). So it is to this reflection that is dedicated the research presented in this article. Firstly will be presented studies in France and abroad about the description of practices. The second part will focus on the effects induced by them on students. Finally, we will present an innovative viewpoint of research, on the relationship betwe…

Carry a big stick, or no stick at all

2016

We investigate the effect of costly punishment in a trust game with endowment heterogeneity. Our findings indicate that the difference between the investor and the allocator’s initial endowments determines the effect of punishment on trust and trustworthiness. Punishment fosters trust only when the investor is wealthier than the allocator. Otherwise, punishment fails to promote trusting behavior. As for trustworthiness, the effect is just the opposite. The higher the difference between the investor and the allocator’s initial endowments, the less willing allocators are to pay back. We discuss the consistency of our findings with social preference models (like inequality aversion, reciprocit…

Immunopathology of leishmaniasis: an update.

2007

Leishmaniasis represents a severe, increasing, public health problem. The perspective of its control is highly dependent on research progress, on therapeutic manipulations of the immune system, and on vaccine development. There is a correlation between the clinical outcome of Leishmania infection and the cytokine response profile. While a protective immune response against Leishmania has been clearly identified to be related to the influence of a type-1 response and IFN-γ production, the precise role of T helper (TH) 2 cytokines in non-healing infections requires further exploration. IL-4 and IL-13 (TH2 cytokines) can promote disease progression in cutaneous leishmaniasis, whereas IL-4 woul…

Enhanced modulation strategy for 7-level voltage waveform in asymmetrical 5-level Cascaded H-Bridge Inverters

2022

The CHBMI performance optimization can be reached both with hardware and software solutions. Generally, asymmetrical configurations allow the extension of the voltage levels number and the implementation of an innovative modulation strategy allows for improving the performance in terms of harmonic distortion and conversion efficiency. This work is devoted to the development of a modulation strategy that allows improving the performance of an asymmetrical single-phase five-level Cascaded H-Bridge Inverter generating a 7-level voltage waveform. Thus, a digital approach and corresponding digital functions are presented. Subsequently, the impact of the dead time and the influence on the voltage…

Animal Model for Cutaneous Leishmaniasis

2012

Using cutaneous leishmaniasis of mice, the existence of so-called T helper (Th) cells type 1 and type 2 had been identified more than 20 years ago. Nowadays, it is well accepted that additional T cell populations as well as B cell-mediated immunity is required for immunity against Leishmania major. Finally, using inbred mouse strains, the relevance of genetical factors that influence anti-pathogen immunity as well as elements of the skin-immune system have been identified. This protocol describes a model for murine experimental leishmaniasis that tries to mimic natural parasite transmission by several means: (1) utilization of only infectious-stage parasites that are found in sand fly saliv…

Proposal of reference values of microbiological environment monitoring in foodservice establishments

2015

Introducción: Proponer una nueva referencia microbiológica ambiental en los servicios de restauración. Objetivo: El presente trabajo muestra la determinación y evaluación de la contaminación microbiológica generada en un establecimiento de servicio de alimentos. Método: Se basa en el muestreo microbiológico de superficie utilizando filtros de membrana de ésteres mixtos de celulosa y en el muestreo de aire utilizando placas de Petri. Resultados: Los límites de contaminación se establecieron antes y durante la elaboración de alimentos, mediante el análisis microbiológico de las superficies y del medio ambiente, sistemas de equipos, hasta límites confiables y estableciendo niveles de aceptació…

Developments of innovative methodologies for Marine Relict Sand Deposits (DSMRs) identification and remotely-sensed shoreline extraction

2023

This Industrial PhD project is a part of the theme set out in point “Blu Growth” of the National Strategy of Intelligent Specialization (SNSI) approved by the European Commission, which defines among the objectives the sector that refers precisely to the marine extraction industry: activities of extraction of natural resources from the sea, that can be reported to the ATECO code “08.12.0, Extraction of gravel, sand; extraction of clays and kaolin". The proposal includes research actions aimed at the development of innovative systems and tools useful to identify and study the area where is higher the probability to detect the submerged relict sand deposits in some sector of the Mediterranean…
