Education, intériorisation de la méritocratie et perception des frontières entre groupes sociaux

2006

La présente recherche (qui s'achèvera en 2007-2008) envisage une manière de tester empiriquement la thèse de la reproduction de Bourdieu et Passeron en explorant la perception de la légitimité des inégalités scolaires et de leurs incidences sociales, chez des individus inégalement formés. Elle entend ainsi explorer les relations entre trajectoire scolaire (niveau atteint, mais aussi filière de formation suivie) et intériorisation de la méritocratie et plus largement le jugement sur les inégalités existantes.

Boudon contre Bourdieu : d'où viennent les inégalités scolaires ?

2023

C’est une des polémiques, les plus célèbres de la sociologie française. Pierre Bourdieu et Jean-Claude Passeron expliquent les inégalités sociales à l’école par l’héritage culturel, quand Raymond Boudon considère qu’elles résultent de choix individuels dans une société inégale. Que valent ces explications un demi-siècle plus tard ?

Sociologie de l'école (3ème édition)

2006

06002; Cette troisième édition, totalement refondue, d'un manuel devenu " la " référence sur le monde de l'école, des élèves et des enseignants, explore le domaine de manière systématique et objective, et sous des aspects divers : place de l'école dans la société (politiques scolaires, inégalités de carrière, enjeux de la réussite scolaire, évolution des analyses théoriques), mais aussi acteurs et pratiques (profession enseignante, programmes, pratiques éducatives des familles, métiers d'élève). Outre la mise à jour de toutes les données et une actualisation générale de son contenu, l'ouvrage propose de nombreux éléments inédits sur les effets des politiques éducatives, la construction et l…

L’intériorisation de la méritocratie, clé de sa reproduction

2022

2014

Oviparous females have three main options to increase their reproductive success: investing into egg number, egg mass and/or egg care. Although allocating resources to either of these three components is known to shape offspring number and size, potential trade-offs among them may have key impacts on maternal and offspring fitness. Here, we tested the occurrence of phenotypic trade-offs between egg number, egg mass and maternal expenditure on egg care in the European earwig, Forficula auricularia, an insect with pre- and post-hatching forms of maternal care. In particular, we used a series of laboratory observations and experiments to investigate whether these three components non-additivel…

Delayed Fatherhood in Mice Decreases Reproductive Fitness and Longevity of Offspring1

2009

Abstract This study aims to analyze, in mice, the long-term effects of delayed fatherhood on reproductive fitness and longevity of offspring. Hybrid parental-generation (F0) males, at the age of 12, 70, 100, and 120 wk, were individually housed with a randomly selected 12-wk-old hybrid female. The reproductive fitness of first-generation (F1) females was tested from the age of 25 wk until the end of their reproductive life. In F1 males, the testing period ranged from the age of 52 wk until death. Breeding F1 females from the 120-wk group displayed interbirth intervals longer than females from the 12-, 70-, and 100-wk groups. Furthermore, F2 pups begotten by F1 studs exhibited weaning weight…

No evidence for an indirect benefit from female mate preference in Arctic charr Salvelinus alpinus, but female ornamentation decreases offspring viab…

2011

Female mate choice is considered an important evolutionary agent, but there has been an ongoing debate over the fitness consequences it produces, especially in species that have a resource-free mating system. We examined a potential fitness benefit resulting from the pre-spawning mate preference in Arctic charr Salvelinus alpinus, a salmonid fish with no parental care. The females were first allowed to discriminate behaviourally between two males presented to them in a free choice test. We then tested with controlled fertilizations whether the females would accrue indirect genetic benefits for their offspring, as measured by embryonic viability, if they had mated with the male they preferre…

[Rt or RDt, that is the question!]

2021

The article compares two of the most followed indices in the monitoring of COVID-19 epidemic cases: the Rt and the RDt indices. The first was disseminated by the Italian National Institute of Health (ISS) and the second, which is more usable due to the lower difficulty of calculation and the availability of data, was adopted by various regional and local institutions. The rationale for the Rt index refers to that for the R0 index, the basic reproduction number, which is used by infectivologists as a measure of contagiousness of a given infectious agent in a completely susceptible population. The RDt index, on the other hand, is borrowed from the techniques of time series analysis for the tr…
