Global fit to CKM data

International audienceWe present updated results for the CKM matrix elements from a global fit to flavour physics data within the standard model theoretical context. We emphasise recent improvements on the determination of the CKM parameters l and A as well as on the angle g of the unitarity triangle

Simulation of Cosmic Ray neutrinos Interactions in Water

The program CORSIKA, usually used to simulate extensive cosmic ray air showers, has been adapted to a water medium in order to study the acoustic detection of ultra high energy neutrinos. Showers in water from incident protons and from neutrinos have been generated and their properties are described. The results obtained from CORSIKA are compared to those from other available simulation programs such as Geant4.Comment: Talk presented on behalf of the ACoRNE Collaboration at the ARENA Workshop 200

Mathematics Teacher TPACK Standards and Revising Teacher Preparation

What knowledge do teachers need for integrating appropriate digital technologies in teaching mathematics? An overarching construct called TPACK is proposed as the interconnection and intersection of knowledge among technology, pedagogy, and content and is referred to as the total knowledge package for teaching mathematics with technology. Five stages in the process of developing TPACK - recognizing, accepting, adapting, exploring, and adapting – describe the process of teachers’ learning to integrate technology. Teachers learn to teach mathematics from their own learning – K-12 mathematics - collegiate mathematics coursework, teacher preparation program, field experiences and professional development as they teach mathematics. The challenge is to identify appropriate experiences to guide this integration of technology in teaching mathematics in ways that develop TPACK. A framework for these experiences directs attention to emergent social and psychological perspectives

JE NE VEUX PAS FAIRE OU JE NE PEUX PAS FAIRE ? APPORTS EPISTEMOLOGIQUES ET METHODOLOGIQUES DE LA PHILOSOPHIE DE PAUL RICOEUR A LA CRITIQUE DU CONCEPT D'AGENCE

La théorie des incitations, rapprochée de la théorie de l'agence dans le champ comptable, comprend deux grandes dimensions, le vouloir agir et le pouvoir agir, mais cette dernière composante n'a été que très peu analysée. Les travaux de Paul Ricoeur permettent de montrer qu'en s'intéressant exclusivement aux incitations comme un correctif de la (mauvaise) volonté des agents, la théorie de l'agence nie la capacité d'agir de ceux-ci et risque ainsi de favoriser des dispositifs de gestion qui augmentent l'incapacité. Pour répondre au défi méthodologique posé par cette nouvelle perspective, nous présentons la théorie des construits personnels et la technique du repertory grid élaborées par George Kelly.incitations ; théorie de l'agence ; Paul Ricoeur ; capacité d'agir ; grille de Kelly
