L'aide individualisée en seconde, mise en route et premiers effets d'une innovation pédagogique
2001
International audience; A la suite de la première année de fonctionnement, le dispositif d'aide individualisée en seconde s'est révélé comme étant peu efficace sur les résultats scolaires des élèves. Le caractère peu ciblé du dispositif, une incohérence relative dans l'allocation des moyens aux établissements, le faible nombre de séances suivies par les élèves sont des éléments qui peuvent sans doute expliquer ce résultat décevant de l'évaluation d'une innovation récente qui devrait évoluer.
De la performance musicale dans la Guyane traditionnelle : expression cognitive singulière d?une musique-verbe
2021
Guianese culture and traditional music, here evoked, are various. It is more a transcultural process that, along centuries, gave an original result born in the Americas, in Guiana in this case. It is a form of refoundation, of recreation of cultures and new human beings generally called Creoles. The musical performance, that I study here, is the echo of social and cultural space of this reformulation of thought, life, and conception of the world. It is, as well, a mean of transposition and transformation of the values issued of diverse sources and categories. It is in no way a second-rate cultural practice, as it is the place where were born philosophies and actions for common life as well …
Determination of enrichment factors for modified RNA in MeRIP experiments
2019
In the growing field of RNA modification, precipitation techniques using antibodies play an important role. However, little is known about their specificities and protocols are missing to assess their effectiveness. Here we present a method to assess enrichment factors after MeRIP-type pulldown experiments, here exemplified with a commercial antibody against N6-methyladenosine (m6A). Testing different pulldown and elution conditions, we measure enrichment factors of 4-5 using m6A-containing mRNAs against an unmodified control of identical sequence. Both types of mRNA carry 32P labels at different nucleotides, allowing their relative quantification in a mixture after digestion to nucleotides…
Macrophage migration inhibitory factor is critically involved in basal and fluoxetine-stimulated adult hippocampal cell proliferation and in anxiety,…
2011
Intensive research is devoted to unravel the neurobiological mechanisms mediating adult hippocampal neurogenesis, its regulation by antidepressants, and its behavioral consequences. Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine that is expressed in the CNS, where its function is unknown. Here, we show, for the first time, the relevance of MIF expression for adult hippocampal neurogenesis. We identify MIF expression in neurogenic cells (in stem cells, cells undergoing proliferation, and in newly proliferated cells undergoing maturation) in the subgranular zone of the rodent dentate gyrus. A causal function for MIF in cell proliferation was shown using genetic (M…
Adaptive and Creative Problem-Projects in the Teaching of Science. Description of the Methodology and Appreciation of the Students Involved
2019
En este artículo se describe la metodología que se ha denominado Aprendizaje Basadoen Problemas-Proyectos Adaptativos y Creativos (ABPac), utilizando como ejemplo algunos de losproyectos realizados en el centro concertado Jesús-María de Burgos durante diez años, entre 2006y 2016, con alumnos de Secundaria Obligatoria y Bachillerato. Esta metodología sugiere una aten-ción a la diversidad del alumnado considerando sus necesidades e inquietudes. Además, se analizacuantitativamente el resultado de la encuesta de percepción realizada a 73 individuos involucradosen esta metodología cuando ya ha transcurrido un tiempo de madurez y se encuentran finalizandosus carreras o con estas ya finalizadas.

The role of psychological inflexibility in adolescent satisfaction with the educational track and school dropout intentions
2022
This study aimed to obtain novel understanding of the associations between psychological inflexibility and adolescents' engagement with upper secondary studies. The participants were 885 Finnish adolescents (mean age 15.74 at the outset) whose psychological inflexibility was measured with the short form of the Acceptance and Fusion Questionnaire for Youth (AFQ-Y8) in the fall of the final (ninth) grade of basic education. School engagement was measured as satisfaction with the educational track and as school dropout intentions, and they were measured twice in the first study year after the transition to upper secondary education. The results showed that high psychological inflexibility in t…
Immunogenicity and reactogenicity of a Haemophilus influenzae type b tetanus conjugate vaccine when administered separately or mixed with concomitant…
1998
With an increasing number of new vaccines available for routine childhood immunization, combination vaccines are needed in order to maintain or achieve a high compliance with recommended immunization programmes. In a prospective, randomized, comparative, multi-centre study, 822 healthy infants were enrolled to receive three doses of either a candidate or a commercially available Haemophilus influenzae type b (Hib) vaccine concomitantly with diphtheria-, tetanus- acellular pertussis (DTaP) vaccine. Study subjects were randomly allocated to one of the following groups: (1) separate, or (2) mixed injection of DTaP and candidate Hib vaccine, or (3) separate injection of DTaP and commercial Hib …
“Narrative Museums” and Curators’ Rights: The Protection of a Museum Exhibition and Its Scenario under Polish Law
2020
Since at least the 1990s, museums have expanded to cover a variety of societal functions, often enabling inclusive and participatory spaces for critical dialogue about the past and the future, and bridging together various narratives and cultural experiences, contributing to social cohesion and reconciliation. The new functions of museums, involving novel technological forms of display and communication, pose several legal questions concerning the management of such institutions, their resources, and exhibitions, including issues of copyright and other intellectual property rights. While referring to a recent case concerning an alleged infringement of the moral rights of the authors of the …
Multisummability for generalized power series
2022
We develop multisummability, in the positive real direction, for generalized power series with natural support, and we prove o-minimality of the expansion of the real field by all multisums of these series. This resulting structure expands both $\mathbb{R}_{\mathcal{G}}$ and the reduct of $\mathbb{R}_{\mathrm{an}^*}$ generated by all convergent generalized power series with natural support; in particular, its expansion by the exponential function defines both the Gamma function on $(0,\infty)$ and the Zeta function on $(1,\infty)$.
L'allocation de ressources par élève dans le système éducatif français : point de vue d'un économiste
1993
This article examines why it is interesting to have a better knowledge of unit costs in educational systems, and to analyse differences between levels of education, between schools and between countries. It underlines the fact that few studies have been carried out up to now, and that little agreement exists among specialists concerning the methodologies for estimating costs. In spite or these deficiencies in available information, the author reviews existing case studies in France and in the world, and shows that extensive possibilities of improving the cost-effectiveness of ressources allocation still exist. Comparisons between France and its economic partners show that French unit costs …
