Cost and Financing of Education and its Impact on Coverage and Quality of Services and Efficiency and Equity in Sub-Saharan African Countries
2007
07052; In this chapter, we take mostly an international comparative perspective limited to Sub-Saharan African countries. First, we analyse first the macro picture and the public finance dimension, analyzing the systemic choices made in the distribution of public resources across levels and types of education. Second, we move to unit cost estimates and the factors accounting for their level in a given country and to their variation across the different countries of the region. Finally, we examine the implication of the choices made in the financial dimension upon outcomes (coverage and quality of educationl services), birnging issues of efficiency and equity into the analysis.
Differential polyadenylation pattern of ovalbumin precursor RNAs during development.
1986
The expression of the ovalbumin gene encoding for the major hen oviduct protein slows down with age. Analysis of Northern blots of electrophoretically separated total and poly(A) + RNA from oviducts of hens of different age with an ovalbumin-specific probe (nick-translated 9.5 kb ovalbumin gene DNA cloned into pBR322) revealed that the largest high molecular weight ovalbumin RNA precursor (7.9 kb band, representing the putative primary transcript of the ovalbumin gene) was most intense if total RNA from non-egg-laying old hen oviduct was checked as compared to that from egg-laying mature animals. On the other side, the 7.9 kb RNA precursor band was readily detected in the poly(A) + RNA from…
Optical Studies of Amphiphilic Molecules with Interesting Electro-Optical and Non-Linear Optical Properties
1990
Structural control is a major issue in both life science, investigating the function of the biological machinery, and in materials science, aiming at the design of novel devices. In part one, recent electro-optical investigations of the primary event of photosynthesis on purified protein preparations are described. Part two focuses on structural studies of monolayers at an air/water interface, and of Langmuir-Blodgett multilayers from a new molecule designed for nonlinear optical applications.
Fresh Human Orthotopic Ovarian Cortex Transplantation: Long-term Results
2006
An increasing number of young women are being diagnosed with cancer, and most cancer treatments have irreversibly negative effects on reproduction. Ovarian stimulation and preservation of oocytes or embryos is far from an ideal solution, in part because hormonal treatment may adversely affect some cancers. Another possibility is cryopreservation of ovarian tissue for later autotransplantation, but the ischemic damage caused by the procedure can lead to follicle loss. Using the ovarian medulla for orthotopic ovarian cortex transplantation might limit the risk of ischemia because the ovarian artery would assure a good blood supply. In addition, the medulla may have a role in follicular develo…

Identification des compétences à l'école élémentaire :une approche empirique à partir des évaluations institutionnelles
2007
Cet article propose une analyse des résultats des élèves aux évaluations nationales, l’objectif étant de mieux comprendre comment les acquisitions se structurent à l’école primaire. L’intérêt de cette démarche réside principalement dans l’identification de compétences dont la maîtrise est essentielle à la réussite scolaire. L’approche choisie pour traiter la question est résolument empirique et se base sur l’examen des relations statistiques entre les items. Elle permet de répondre à plusieurs questions susceptibles d’intéresser les chercheurs en éducation, mais aussi les acteurs engagés, à différents degrés, dans le pilotage et la gestion pédagogique de l’enseignement primaire. Les évaluat…
Energy and economic analysis and feasibility of retrofit actions in Italian residential historical buildings
2016
Abstract The application of retrofit actions to existing building stocks can improve the energy performance of the residential sector. In this context, particular attention should be given to historical buildings, which represent a large part of the Italian building stock. To improve the energy performance of them, adequate retrofit actions must be applied. Many studies and regulations have focused on identifying the best refurbishment measures. However, the selection of these measures is difficult due to restrictive regulations, which are dictated by the Ministry of Cultural Heritage and Activities, high retrofit costs, and variable climate zones. Thus, energy renovations in Italian buildi…
Life cycle energy performances and environmental impacts of a prefabricated building module
2018
Abstract The paper explores the energy performances and environmental impacts of a prefabricated building module located in Messina (Sicily, Italy) through an approach that combines both the non-steady state building simulation and the Life Cycle Assessment methodology. The building uses renewable energy technologies and is usable in emergency situations or as simply temporary housing. Results show that the building module causes the emission of 1.5 t of CO2eq/m2 and consumes 29.2 GJ/m2 of primary energy during its life cycle. The building achieves the Net Zero Energy Building target even if it has relevant environmental impacts in the materials production stage (72% on average of the total…
Formación artística en el grado de maestro de primaria de la Universitat de València. Enfoques y propuestas
2014
Este trabajo presenta una propuesta enfocada a mejorar la docencia en el actual grado de maestro de Primaria en lo que a Educación Artística se refiere, según el plan de estudios de la Facultat de Magisteri de la Universitat de València. La implantación del grado es relativamente reciente con lo cual permite plantearse mejoras que conlleven dotar a los futuros maestros de herramientas que optimicen sus conocimientos del área artística. Así, se llevará a cabo una colaboración horizontal basada en la cooperación entre profesores de las diferentes áreas artísticas: Educación Plástica y Música. Por ello, se plantea la puesta en práctica de una metodología innovadora de índole cooperativa, revis…
Sphères privée et professionnelle chez les enseignants du premier degré : comment priorisent-ils ?
2019
Private and professional lives among primary teachers: how they prioritize? Being a teacher in primary school seems far from allowing the articulation of work and private life in such a comfortable manner as seen in collective beliefs. In order to deconstruct the belief considering teachers as privileged, this contribution proposes, based on empirical results (an online survey with 21,642 responses), to report, first, how primary teachers prioritize their private or professional lives. Second, this paper highlights the reasons which lead them to favour one of the two fields, notably when priority is given to private life at the expense of professional life. Referring to the issue of work-fa…
