The competency-based approach in developing countries : effects of curricular reforms in Sub-Saharan Africa

2013

For decades, all analyzes converge on the idea of the relative inefficiency of education systems in sub-Saharan Africa. Dropout, repetition, overstaffing, low quality of learning student failure and obsolescence of facilities, teaching materials and teachers, including sometimes the levels and quality of education remain somewhat uncertain, inadequate educational programs. In short, these are some of the ills that plague these systems and confirm the findings made by many reports. Given this weakness finding, educational authorities, supported by international aid mobilized in many countries to improve their systems to qualitatively, but also quantitatively equity because we must not forget…

Les langues, facteurs du rendement en lecture dans les évaluations PIRLS

2011

The starting point of this research is the question, may reading acquisition be more or less effective depending on the language in which it is perform? Two categories for classifying the languages have been developed. First the notion of linguistic family is employed to describe the languages from a cultural and historical perspective. Secondly, the notion of orthographic depth is used for differentiating the languages according to the correspondence between orthography and phonetic. These categories have been related to the databases PIRLS 2001 and 2006 (international assessments about reading developed by the IEA), the aim being to connect reading achievement to the language in which stu…

Spatial effects in housing price models : do housing prices capitalize urban development policies in the agglomeration of Dijon (1999) ?

2004

In this article we suppose that the integration of accessibility and neighborhood variables in hedonic housing models doesn't allow to take into account the spatial effects between the housing prices. Using a sample of 1520 transactions of apartments in the urban area of Dijon, we focus on two types of location variables : the distance to the CBD and the distance to several Disadvantaged Districts located in peripheral areas. We detect the presence of a spatial error autocorrelation in the hedonic model indicating that the valuation of the price of an apartment is locally influenced by the prices of the neighboring apartments. Then, we estimate a spatial error model which shows that the loc…

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…

Contributions to the study of returns to education : the Tunisian case

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 …

Les élèves en accompagnement scolaire : adéquation entre public visé et public accueilli

2002

This article examines the adjustment between pupils targeted to study in after school programs and pupils who are already in attendance. Several analyses have been drawn up on a large cross-section of seven and ten year-old pupils and have shown that most of them have social problems and/or are under-achieving. However, a third of the cross-section are not experiencing difficulties and therefore should not have been enrolled. Regarding the selection process of the after school programs, the analysis also shows that weak and foreign pupils more frequently seek school support after the normal school day.

Utilisation du numérique par les enseignants à l’université : description et analyse des facteurs explicatifs

2019

Dans cet article, nous nous intéressons à la nature des technologies de l’information et de la communication (TIC) mobilisées par les enseignants universitaires pour enseigner et aux facteurs explicatifs de cette utilisation. Nous procédons d’abord à un éclairage théorique notamment concernant les concepts de « TIC » et d’« utilisation ». Puis, à l’appui des données recueillies en mai 2016 auprès de 248 enseignants d’une université française, nous montrons que les TIC mobilisées par les enseignants à l’intérieur, mais aussi en dehors des heures de cours, sont plutôt d’ordre générique en opposition aux technologies plus sophistiquées. Les enseignants utilisent par ailleurs davantage les TIC …

L’historien et ses modèles

2010

Parler des modèles en histoire est une affaire délicate, car le mot recouvre des pratiques historiennes différentes depuis son apparition dans la discipline, après la dernière guerre mondiale. Pour une minorité d’historiens surtout spécialisés en histoire économique, il correspond à une vision nouvelle de la discipline qui tenterait d’intégrer certaines démarches mathématiques, en particulier aujourd’hui la théorie des jeux. Pour d’autres, en revanche, parler de modèles relèverait surtout d’une évolution du vocabulaire, sans impliquer de véritable mutation disciplinaire. Les historiens construisent et utilisent surtout des modèles explicatifs, voire palliatifs quand ils ont de trop grandes …

Thermodynamic limit of particle-hole form factors in the massless XXZ Heisenberg chain

2010

We study the thermodynamic limit of the particle-hole form factors of the XXZ Heisenberg chain in the massless regime. We show that, in this limit, such form factors decrease as an explicitly computed power-law in the system-size. Moreover, the corresponding amplitudes can be obtained as a product of a "smooth" and a "discrete" part: the former depends continuously on the rapidities of the particles and holes, whereas the latter has an additional explicit dependence on the set of integer numbers that label each excited state in the associated logarithmic Bethe equations. We also show that special form factors corresponding to zero-energy excitations lying on the Fermi surface decrease as a …
