A discourse analysis of trainee teacher identity in online discussion forums
Teacher education involves an identity transformation for trainees from being a student to being a teacher. This discourse analysis examined the online discussion board communications of a cohort of trainee teachers to better understand the situated identities of the trainees and how they were presented online. Their discussion board posts were the primary method of communication during placement periods and, as such, provided insight into how the trainees situated their identities in terms of being a student or being a teacher. During the analysis, the community boundaries, language and culture were explored along with the tutor's power and role in the identity transformation process. This involved looking at the lexis used by the students, the use of pronouns to refer to themselves and others such as teachers and pupils, the types of messages allowed in the community and the effect of the tutor's messages on their communication. The research found that the trainees felt comfortable with teaching but did not feel like teachers during the course. Tutors and school teachers need to develop an awareness of the dual nature of trainees' identities and help promote the transition from student to teacher. In the beginning of the course, trainees should be familiarised with teacher vocabulary and practical concepts in addition to pedagogical theory. Towards the end of the course, trainee identity as teachers could be promoted through the use of authentic assessments that mirror real teacher tasks and requirements

Quelle stratégie de renouvellement pour le pin sylvestre de Lozère ? Les possibilités de régénération naturelle.
En Lozère le pin sylvestre a été peu intégré dans l'assolement : colonisation des terres en jachère et coupe rase avant la mise en culture. Mais le contexte agricole a changé, les friches moins nombreuses, sont plutôt utilisées en pâturage. Sur certaines parcelles, quasiment aucune régénération n'a été observée. La plantation en Lozère n'est quasiment pas pratiquée, ainsi la régénération naturelle, insuffisante, nécessite une intervention extérieure pour obtenir une densité suffisante (une méthode de décapage par godet a été expérimentée par l'ONF)
Quasiparticle RPA with finite rank approximation for Skyrme interactions
A finite rank separable approximation for the particle-hole RPA calculations
with Skyrme interactions is extended to take into account the pairing. As an
illustration of the method energies and transition probabilities for the
quadrupole and octupole excitations in some O, Ar, Sn and Pb isotopes are
calculated. The values obtained within our approach are very close to those
that were calculated within QRPA with the full Skyrme interaction. They are in
reasonable agreement with experimental data.Comment: 20 pages, 1 figure, submitted to Phys.Rev.
