Interactions personnelles et sociales et identité professionnelle
Lâobjet de cet article est dâexaminer la dimension du processus de construction identitaire qui concerne lâidentification Ă autrui. Lâanalyse des rĂ©cits de vie dâenseignantes dâexpĂ©rience permet de mettre en Ă©vidence des aspects de la structure sociale qui façonnent le devenir des enseignants dans leur appropriation professionnelle, personnelle, singuliĂšre et existentielle de leur identitĂ© professionnelle.1 This study examines the dimension of the identity construction process relating to identification with others. Our analysis of experienced teachersâ life stories reveals aspects of the social structure that shape teachersâ evolution in their personal, professional, particular and existential appropriation of a professional identity.
Genome-wide linkage scan reveals multiple susceptibility loci influencing lipid and lipoprotein levels in the Québec Family Study
A genome-wide linkage study was performed to identify chromosomal regions harboring genes influencing lipid and lipoprotein levels. Linkage analyses were conducted for four quantitative lipoprotein/lipid traits, i.e., total cholesterol, triglyceride, HDL-cholesterol (HDL-C), and LDL-C concentrations, in 930 subjects enrolled in the Québec Family Study. A maximum of 534 pairs of siblings from 292 nuclear families were available. Linkage was tested using both allele-sharing and variance-component linkage methods. The strongest evidence of linkage was found on chromosome 12q14.1 at marker D12S334 for HDL-C, with a logarithm of the odds (LOD) score of 4.06. Chromosomal regions harboring quantitative trait loci (QTLs) for LDL-C included 1q43 (LOD = 2.50), 11q23.2 (LOD = 3.22), 15q26.1 (LOD = 3.11), and 19q13.32 (LOD = 3.59). In the case of triglycerides, three markers located on 2p14, 11p13, and 11q24.1 provided suggestive evidence of linkage (LOD > 1.75). Tests for total cholesterol levels yielded significant evidence of linkage at 15q26.1 and 18q22.3 with the allele-sharing linkage method, but the results were nonsignificant with the variance-component method. In conclusion, this genome scan provides evidence for several QTLs influencing lipid and lipoprotein levels. Promising candidate genes were located in the vicinity of the genomic regions showing evidence of linkage
Redefining professional identity: the voice of a language teacher in a context of collaborative learning
Following a narrative and biographic approach, in this study, we present the case of an in-service language teacher and her professional learning trajectory in the context of the project âLanguages and education: constructing and sharing train- ingâ. This project aimed at the construction of a collaborative teacher education context for learning and transformation of experiences, views and practices in language education, and involved teachers, teacher educators and researchers. Based on a single case study, the analysis tries to disclose the teacherâs discur- sive displacements as hints of professional transformation while she reinterprets the learning taking place in the collaborative education process. The signs of change are visible in the way she constructs meanings regarding her professional identity, re-identifies her mission as a language teacher and reconsiders her pro- fessional identity. Finally, we reflect upon how collaborative teacher education scenarios may foster teachersâ personal professional learning and renewed self- images
«La relation de limitation et dâexception dans le français dâaujourdâhui : exceptĂ©, sauf et hormis comme pivots dâune relation algĂ©brique »
Lâanalyse des emplois prĂ©positionnels et des emplois conjonctifs dâ âexceptĂ©â, de âsaufâ et dâ âhormisâ permet dâenvisager les trois prĂ©positions/conjonctions comme le pivot dâun binĂŽme, comme la plaque tournante dâune structure bipolaire. PlacĂ©es au milieu du binĂŽme, ces prĂ©positions sont forcĂ©es par leur sĂ©mantisme originaire dĂ»ment mĂ©taphorisĂ© de jouer le rĂŽle de marqueurs dâinconsĂ©quence systĂ©matique entre lâĂ©lĂ©ment se trouvant Ă leur gauche et celui qui se trouve Ă leur droite. Lâopposition qui surgit entre les deux Ă©lĂ©ments nâest donc pas une incompatibilitĂ© naturelle, intrinsĂšque, mais extrinsĂšque, induite. Dans la plupart des cas (emplois limitatifs), cette opposition prend la forme dâun rapport entre une « classe » et le « membre (soustrait) de la classe », ou bien entre un « tout » et une « partie » ; dans dâautres (emplois exceptifs), cette opposition se manifeste au contraire comme une attaque de front portĂ©e par un « tout » Ă un autre « tout ». De plus, lâinconsĂ©quence induite mise en place par la prĂ©position/conjonction paraĂźt, en principe, tout Ă fait insurmontable. Dans lâassertion « les Ă©cureuils vivent partout, sauf en Australie » (que lâon peut expliciter par « Les Ă©cureuils vivent partout, sauf [quâils ne vivent pas] en Australie »), la prĂ©position semble en effet capable dâimpliquer le prĂ©dicat principal avec signe inverti, et de bĂątir sur une telle implication une sorte de sous Ă©noncĂ© qui, Ă la rigueur, est totalement inconsĂ©quent avec celui qui le prĂ©cĂšde (si « les Ă©cureuils ne vivent pas en Australie », le fait quâils « vivent partout » est faux). NĂ©anmoins, lâanalyse montre quâalors que certaines de ces oppositions peuvent enfin ĂȘtre dĂ©passĂ©es, dâautres ne le peuvent pas. Câest, respectivement, le cas des relations limitatives et des relations exceptives. La relation limitative, impliquant le rapport « tout » - « partie », permet de rĂ©soudre le conflit dans les termes dâune somme algĂ©brique entre deux sous Ă©noncĂ©s pourvus de diffĂ©rent poids informatif et de signe contraire. Les valeurs numĂ©riques des termes de la somme Ă©tant dĂ©sĂ©quilibrĂ©es, le rĂ©sultat est toujours autre que zĂ©ro. La relation exceptive, au contraire, qui nâimplique pas le rapport « tout » - « partie », nâest pas capable de rĂ©soudre le conflit entre deux sous Ă©noncĂ©s pourvus du mĂȘme poids informatif et en mĂȘme temps de signe contraire : les valeurs numĂ©riques des termes de la somme Ă©tant symĂ©triques et Ă©gales, le rĂ©sultat sera toujours Ă©quivalent Ă zĂ©ro
A new 4D variational assimilation method of spaceborne data for moisture
For the last years, a great number of new space-borne platforms and radiometric instruments have been launched in order to document the dynamic, thermodynamic and microphysic properties of the atmosphere. For instance SSMI on DMSP, TMI on TRMM, MODIS on AQUA...brings informations on precipitation and water vapor; GOES, MSG...allow to access to horizontal winds; AIRS on AQUA, IASI on MetOp-1 to vertical profiles of temperature and humidity. Thus a need of new analyses to process and merge these data is appeared. In this context, this paper presents a new 4D variational data assimilation method to retrieve 4D fields from space-borne data such as wind, specific humidity and related quantities (pressure, temperature, vorticity potential, apparent heat source, apparent moisture sink, evaporation rate, condensation rate). This method is based on an analytical representation of these fields which are adjusted to the data through a variational process using additionnal constraints linked to physical equations (mass conservation, boundary condition, water mass conservation, vorticity production ...). This paper will focus on this mathematical formulation and its relevant avantages. Sensitivity tests on used dataset synthetised from a non-hydrostatic meso-scale numerical simulation will be discuss. An illustration will be also given on a particular real dataset (SSMI, TMI, GOES, QuikSCAT products and dropsoundings, radiosooundings) devoted to the documentation of the moisture budget of the BRET hurricane observed over the Gulf of Mexico in august 1999
