À bas la sélection ! Misère de la critique
2019
International audience; La critique de la sélection à l'entrée de l'université repose sur une vision misérabiliste des étudiants de milieu populaire et ne remet pas en question les inégalités au sein du système d'éducation. Il existe sans doute mille bonnes raisons d'être hostile à Parcoursup et à la réforme du baccalauréat, comme il existe de solides raisons de protester contre les conditions de travail des professeurs, des enseignants-chercheurs et des étudiants… Le propos de ce texte n'est pas de participer aux débats sur le bien-fondé des réformes ; il n'est ni de les défendre ni de les contester, mais d'interroger les cadres de la critique de la sélection que ces réformes sont censées …
Direct observation of the Ba 114 → Xe 110 → Te 106 → Sn 102 triple α -decay chain using position and time correlations
2016
The triple α-decay chain 114Ba → 110Xe → 106Te → 102Sn has been directly observed for the first time, following the 58Ni(58Ni ,2n) reaction. Implantation of 114Ba nuclei into a double-sided silicon-strip detector has allowed their α decays to be correlated in position and time with the α decays of the daughter (110Xe) and granddaughter (106Te) nuclei. In total, 17 events have been assigned to the 114Ba → 110Xe → 106Te → 102Sn triple α-decay chain. The energy of the 114Ba α decay has been measured to be Eα = 3480(20) keV, which is 70 keV higher than the previously measured value, and the half-life of 114Ba has been measured with improved accuracy, to be 380+190 −110 ms. A revised Q12C value …
A joint reading of positional and relational goods
2013
Both relational and positional goods are based upon an idea of joint consumption - though with opposite signs. Indeed, in both cases, individuals' consumption choices take into account not only the individuals themselves, but others, as well. Given that relational goods provide a form of identity to their consumers, we show that a certain degree of positionality emerges within the consumption of relational goods. Analogously, except in a two-agent context, each positional good also has a relational component. What emerges is a complex structure of economic outcomes based on both relational and positional motives.
Duality-invariant dispersion relations for electromagnetic and gravitational waves at Planck scales
2012
In this paper we explore some mathematical aspects of a duality-invariant Einstein-Planck relation on electromagnetic waves and gravitational waves at a Planckian scale. We explore a generalized version of Maxwell's equations leading to the proposed duality-invariant dispersion relation for electromagnetic waves. We also study the analogous aspects of duality in a post-Newtonian description of gravitational waves.

$\mathrm{pD^-}$ $\oplus$ $\mathrm{\overline{p}D^+}$ momentum correlation function as a function of the relative momentum in the particle-pair rest frame $k^*$ in high-multiplicity (0-0.17%) pp collisions at $\sqrt{s}=13$ TeV.
Azimuthal correlations of prompt D mesons with charged particles in pp and p–Pb collisions at √sNN = 5.02 TeV
2020
The measurement of the azimuthal-correlation function of prompt D mesons with charged particles in pp collisions at √s = 5.02 TeV and p–Pb collisions at √sNN = 5.02 TeV with the ALICE detector at the LHC is reported. The D0D0, D+D+, and D∗+D∗+ mesons, together with their charge conjugates, were reconstructed at midrapidity in the transverse momentum interval 30.3 GeV/c and pseudorapidity |η|<0.8. The properties of the correlation peaks appearing in the near- and away-side regions (for Δφ≈0 and Δφ≈π, respectively) were extracted via a fit to the azimuthal correlation functions. The shape of the correlation functions and the near- and away-side peak features are found to be consistent in pp a…

Les parents face aux pratiques numériques adolescentes
2023
Fondée sur une enquête qualitative par entretiens semi-directifs auprès de 28 parents d’adolescents, cette contribution empirique s’intéresse à la parentalité à l’ère du numérique. Elle cherche notamment à se saisir des représentations des parents vis-à-vis des pratiques numériques de leurs adolescents et de la manière dont elles influencent l’écologie relationnelle au sein du foyer. Les résultats mettent en valeur la connaissance (réelle ou fantasmée) qu’ont les parents des pratiques de leurs ados. L’enquête montre que les parents se sentent démunis mais néanmoins conscients de l’importance de leur rôle éducatif. Entre contrôle et négociation, le dialogue parent-enfant autour des questions…
