Identification of predictive biomarkers for the efficacy of nivolumab in patients with advanced non-small cell cancer.
2019
The recent introduction of immunotherapy has disrupted the management of non-small cell lung cancer (NSCLC). Nivolumab, an antibody targeting the immune checkpoint inhibitor PD-1, has shown remarkable results in seconde-line setting after failure of standard first-line chemotherapy. However, only a quarter of patients benefits from this therapy. To date, no predictive biomarker of the therapeutic efficacy of nivolumab has been identified in a clear and consensual manner. The research for predictive biomarkers of efficacy or resistance to this treatment is, therefore, a major challenge.The emergence of high-throughput sequencing over the past decade has had a significant impact on clinical a…
Analyse des procédures d'orientation au palier de troisième
1983
Texte de la communication présentée au colloque sur « Les inégalités dans l'Enseignement secondaire» (IREDU, Dijon, 27-28 mai 1982).; International audience; Outre la présentation d'un modèle théorique de l'orientation (fondé sur des arbitrages entre l'intérêt que présentent les études et le risque d'y échouer) et le rappel des principales différenciations (sociales, scolaires, par âge ...) opérées à l'entrée dans le second cycle, l'essentiel du texte porte sur l'analyse du fonctionnement de la commission d'orientation. On y examine en premier lieu comment la procédure dans son ensemble prend en compte de façon simultanée toutes les caractéristiques "scolaires" de l'élève et la pondération …
L'approche sociologique des effets du contexte scolaire: méthodes et difficultés
2005
05058; International audience; L'analyse des effets contextuels dans le domaine de l'éducation constitue un champ derecherche en plein développement, dont les enjeux sont autant scientifiques que politiques.Le texte présente de manière précise comment les chercheurs en Education dont l'orientationest sociologique (ou économique) abordent ces questions, à partir d'une enquête récente,conduite au niveau de l'école primaire française, permettant d'évaluer et d'explorer ce typed'effets, en se focalisant sur l'influence de la composition sociale de la classe fréquentée. Letexte explicite la démarche et les étapes successives suivies, les modèles statistiques estiméset les difficultés méthodologi…
Timing and patterns of the ENSO signal in Africa over the last 30 years: insights from normalized difference vegetation index data.
2014
Abstract A more complete picture of the timing and patterns of the ENSO signal during the seasonal cycle for the whole of Africa over the three last decades is provided using the normalized difference vegetation index (NDVI). Indeed, NDVI has a higher spatial resolution and is more frequently updated than in situ climate databases, and highlights the impact of ENSO on vegetation dynamics as a combined result of ENSO on rainfall, solar radiation, and temperature. The month-by-month NDVI–Niño-3.4 correlation patterns evolve as follows. From July to September, negative correlations are observed over the Sahel, the Gulf of Guinea coast, and regions from the northern Democratic Republic of Congo…
Contributions to the study of educational returns
2016
In Tunisia, enrollment rates in tertiary education had soared up over the past two decades. A significant increase of student annual flows imposed the implementation of reforms that led to an increase in the number of higher education institutions and universities. One of the challenges in Tunisia and many African countries is to improve the efficiency of education systems to promote employability and graduates employment. This thesis discuss the question of the efficiency of education from an economic approach based on returns to education in the labor market. The first chapter analyses private returns to education particularly higher education in African countries. Our findings highlight …
3D digitization of transparent objects by polalization techniques in IR & by triangulation in UV
2011
Two non-conventional methods for the 3D digitization of transparent objects via non-contact measurement are reported in this thesis. 3D digitization is a well acknowledged technique for opaque objects and various commercial solutions based on different measurement approaches are available in the market offering different types of resolution at different prices. Since these techniques require a diffused or lambertian surface, their application to transparent surfaces fails. Indeed, rays reflected by the transparent surface are perturbed by diverse inter-reflections induced by the refractive properties of the object. Therefore, in industrial applications like quality control, the transparent …
Les parents et l'école au Québec et en France
2013
Cet article est une participation au rapport de Georges Fotinos "L’état des relations école/parents : "entre méfiance, défiance et bienveillance" "En ligne sur http://www.casden.fr/content/download/375900/2413392/version/1/file/RelationsParentsEcole.pdf; Cet article retrace brièvement l'histoire de la place des parents dans l'école en France et au Québec puis compare la situation actuelle dans les deux pays, avant de voir dans quelle mesure les récits sur l'école dominant dans chaque pays concourent à l'expliquer.
Prevention of occupational injuries moral hazard and complex agency relationship
2001
This paper exploits the results of agency theory with the aim of contributing a new viewpoint and a form for analysis of the current functioning of the occupational injury and disease section of the Social Security system in its mission of providing incentives for prevention. After outlining the organization and specific features of insurance against occupational risks, an initial level of analysis highlights the presence of moral hazard in relations between insurer and company and between company and employee. A second level of analysis and resort to complex agency relationship models, multitask model and third-party model, is necessary to take into account the consequences for occupationa…
Contributions to the study of returns to education : the Tunisian case
