L’établissement d’une norme de qualification sûre
Louis Laurencelle Université du Québec à Trois‐Rivières La sélection de personnel pour un emploi se base souvent sur une norme psychométrique qu’un candidat doit atteindre afin d’être recruté. Or, cette norme est statistique, c’est‐à‐dire calculée sur les mesures d’un simple échantillon de la population concernée, et il s’ensuit une incertitude, voire un risque d’erreur, dans la décision de re...
متن کاملNLTE Spectral Analysis of GW Vir Pulsators
GW Vir variables are the pulsating members in the spectroscopic class of the PG 1159 stars. In order to understand the characteristic differences between pulsating and non-pulsating PG1159 stars, we analyse FUSE spectra of eleven objects, of which six are pulsating, by means of state-of-the-art NLTE model atmospheres. The numerous metal lines in the FUV spectra of these stars allow a precise de...
متن کاملEfficient vir gene induction in Agrobacterium tumefaciens requires virA, virG, and vir box from the same Ti plasmid.
The vir genes of octopine, nopaline, and L,L-succinamopine Ti plasmids exhibit structural and functional similarities. However, we observed differences in the interactions between octopine and nopaline vir components. The induction of an octopine virE(A6)::lacZ fusion (pSM358cd) was 2.3-fold higher in an octopine strain (A348) than in a nopaline strain (C58). Supplementation of the octopine vir...
متن کاملVir tual Campfire - Collaborative Multimedia Semantization with Mobile Social Software
Abstr act. Apart from automated techniques, collaborative multimedia semantic annotation by people, in particular communities of domain experts, are and will be powerful contributors to multimedia semantization. Recently, we extended our LAS server towards an XMPP server, thereby enabling the real time intertwining of communication and the collaborative utilization of remote services, in partic...
متن کاملA new HW Vir binary from the Palomar Transient Factory
We report the discovery of an eclipsing binary – PTF1 J072456+125301– composed of a subdwarf B (sdB) star (g′ = 17.2m) with a faint companion. Subdwarf B stars are core helium-burning stars, which can be found on the extreme horizontal branch. About half of them reside in close binary systems, but few are known to be eclipsing, for which fundamental stellar parameters can be derived. We conduct...
