Le développement de la réflexivité et de l’esprit critique par la médiation de dispositifs mobilisant le savoir-analyser : le cas des ateliers philo-traduction avec des élèves de 4ème primaire et des dispositifs DAPPP et ASAPP avec des étudiants en formation initiale d’enseignement primaire
2020, HENALLUXActe de conférence ou de colloqueAujourd’hui plus que jamais, la question du sens de l’école, de l’éducation et apprentissages est au coeur des enjeux de société. Notre recherche a pour but de mettre en exergue en quoi apprendre à penser par soi-même peut, tout au long de la vie, constituer un point d’appui précieux. Plus largement, de nombreuses situations (sociales, médiatiques, politiques, économiques, environnementales,…) ... -
Regards croisés Haute Ecole – Université – Ecoles secondaires sur l’accompagnement personnalisé et la différentiation au D1 de l’enseignement secondaire
2020, HENALLUXActe de conférence ou de colloqueLe constat d’iniquité du système scolaire en Fédération Wallonie-Bruxelles a engendré ces dernières années l’élaboration d’un Pacte pour un Enseignement d’Excellence et d’un Code de l’Enseignement.

Development and implementation of an end-of-shift clinical debriefing method for emergency departments during COVID-19
2020, HENALLUXArticle scientifiqueBackground: Multiple guidelines recommend debriefing after clinical events in the emergency department (ED) to improve performance, but their implementation has been limited. We aimed to start a clinical debriefing program to identify opportunities to address teamwork and patient safety during the COVID-19 pandemic. Methods: We reviewed existing literature on best-practice guidelines to answer ... -

2015, HENALLUXLivre/Ouvrage ou monographieL'asbl "Les Papillons de Saint-Jacques" organise des pèlerinages sur les chemins de Saint-Jacques de Compostelle pour les personnes à mobilité réduite. Les véhicules existants à ce jour pour le transport de ces personnes sur des chemins de campagne ne sont pas adaptés et nécessitent plusieurs accompagnants. De plus, ils procurent une telle sensation de déséquilibre que beaucoup renoncent. C'est dans ... -
Electron impact ionization of thymine clusters embedded in superfluid helium droplets
2007, HENALLUXArticle scientifiqueEmbedding molecules in helium clusters has become a powerful technique for the preparation of cold targets for spectroscopy experiments, as well as for the assembly of complex, fragile molecular species. We have recently developed a helium cluster source and a pick-up cell to produce neutral beams of doped helium droplets, to be used as targets in studies on electron collisions with molecules of ... -
Spectroscopy and dynamics of the 7,7,8,8-tetracyanoquinodimethaneradical anion
2010, HENALLUXArticle scientifiqueThe photoelectron spectrum of the 7,7,8,8-tetracyanoquinodimethane (TCNQ) radical anion has been measured at 3.1 eV. Additionally, the ultrafast relaxation dynamics of the first excited state (12B3u) of TCNQ have been studied using time-resolved photoelectron spectroscopy, which reveals that it undergoes internal conversion back to the ground state (2B2g) with an associated lifetime of 650 fs ... -
Toward real-time charged-particle image reconstruction using polar onion-peeling
2009, HENALLUXArticle scientifiqueA method to reconstruct full three-dimensional photofragment distributions from their two-dimensional (2D) projection onto a detection plane is presented, for processes in which the expanding Newton sphere has cylindrical symmetry around an axis parallel to the projection plane. The method is based on: (1) onion-peeling in polar coordinates [Zhao et al., Rev. Sci. Instrum. 73, 3044 (2002)] in which ... -
