Analyse didactique clinique des pratiques d'enseignement et de formation: Les effets du déjà-là expérientiel sportif
2016
Cette note de synthèse s'inscrit dans la suite de mes travaux sur les filtres de l'action didactique qui questionnent le " déjà-là " des sujets. Dans le " déjà-là expérientiel ", je m'intéresse ici aux expériences corporelles importantes des sportifs et plus particulièrement à celles vécues par les professeurs d'EPS. M'appuyant à la fois sur les trois temps de la didactique clinique (le déjà-là, l'épreuve et l'après-coup) et sur une introspection, je montre combien ces expériences sportives liées à la spécialité chez les enseignants d'EPS, expériences souvent traduites en épreuves, laissent des traces profondes qui viennent structurer le rapport au corps, le rapport à soi et aux autres de c…
Il dialogo tra Capability Approach e la form-azione delle competenze digitali
2020
Il presente contributo si focalizza su una sfida educativa impellente della contemporaneità: la form-azione della cittadinanza digitale. A partire dal Quadro di riferimento Europeo per le competenze digitali dei cittadini, viene svolta una riflessione basata sull’interconnessione tra il Capability approach e le competenze digitali. Il Capability Approach, sviluppando un orizzonte di senso eticoeconomico-politico basato su: “functioning”, capability” e “agency”, completa e orienta il framework teorico-metodologico dettato dai riferimenti normativi europei sullo sviluppo delle digital skills. L’indagine sulle digital skills può essere un’opportunità per orientare l’azione formativa, in riferi…
Combinations of discourse markers with repairs and repetitions in English, French and Spanish
2020
Abstract Discourse markers have a central role in planning and repairing processes of speech production. They relate with fluency and disfluency phenomena such as pauses, repetitions and reformulations. Their polyfunctionality is challenging and few form-function mappings are stable cross-linguistically. This study combines a functional and a structural approach to discourse markers and their combination with and within repetitions and self-repairs in native English, French and Spanish, in order to establish the inter-relation between these three fluency-related devices and to find potentially universal patterns of use. Qualitative coding and quantitative analyses of categories of markers a…
Extensions and intentions in the rough set theory
1998
Abstract The approach to rough set theory proposed in this paper is based on the mutual correspondence of the concepts of extension and intension. It is different from the well-known approaches in the literature in that the upper approximations and the lower approximations of ‘unknown’ sets are considered as certain families of ‘known’ sets. This approach makes it possible to formulate necessary and sufficient conditions for the existence of operations on rough sets, which are analogous to classical operations on sets. The basic results presented in this paper, based on certain ideas of the second author, were formulated by the first author in his doctoral dissertation prepared under the su…
The structure of the state representation of shift invariant controllable and observable group codes
2000
AbstractIn this paper an investigation on the structure of the canonical trellis section of shift invariant, l-controllable and m-observable group codes is carried out. Necessary and sufficient conditions for a set of group homomorphisms in order that they represent the trellis section of this class of codes are established.
Discretionary fiscal policy over the cycle: new evidence based on the ESCB Disaggregated Approach
2009
This paper explores how discretionary fiscal policies on the revenue side of the government budget have reacted to economic fluctuations in European Union countries. For this purpose, it uses data on legislated revenue changes and structural indicators provided twice per year by National Central Banks of European Union countries in the ESCB framework for analysing fiscal policy. The analysis is based on the estimation of fiscal policy rules linking these measures of legislated fiscal policy changes to the output gap and other control variables. Then, baseline results are compared with regression estimates where variations of cyclically-adjusted indicators are used as proxy for discretionary…
A coupled Finite Volume–Smoothed Particle Hydrodynamics method for incompressible flows
2016
Abstract An hybrid approach is proposed which allows to combine Finite Volume Method (FVM) and Smoothed Particle Hydrodynamics (SPH). The method is based on the partitioning of the computational domain into a portion discretized with a structured grid of hexahedral elements (the FVM-domain ) and a portion filled with Lagrangian particles (the SPH-domain ), separated by an interface made of triangular elements. A smooth transition between the solutions in the FVM and SPH regions is guaranteed by the introduction of a layer of grid cells in the SPH-domain and of a band of virtual particles in the FVM one (both neighboring the interface), on which the hydrodynamic variables are obtained throug…
On the Quest for Defining Organisational Plasticity: A Community Modelling Experiment
2020
PurposeThis viewpoint article is concerned with an attempt to advance organisational plasticity (OP) modelling concepts by using a novel community modelling framework (PhiloLab) from the social simulation community to drive the process of idea generation. In addition, the authors want to feed back their experience with PhiloLab as they believe that this way of idea generation could also be of interest to the wider evidence-based human resource management (EBHRM) community.Design/methodology/approachThe authors used some workshop sessions to brainstorm new conceptual ideas in a structured and efficient way with a multidisciplinary group of 14 (mainly academic) participants using PhiloLab. Th…
Copolymerization of VDF and HFP in Supercritical Carbon Dioxide: A Robust Approach for Modeling Precipitation and Dispersion Kinetics
2012
A kinetic model is developed for the heterogeneous free-radical copolymerization of vinylidene fluoride and hexafluoropropylene in supercritical CO 2. The model accounts for polymerization in both the dispersed (polymer-rich) phase and in the continuous (polymer-free) supercritical phase, for radical interphase transport, diffusion limitations, and chain-length-dependent termination in the polymer-rich phase. A parameter evaluation strategy is developed and detailed to estimate most of the kinetic parameters a priori while minimizing their evaluation by direct fitting. The resulting model predictions compare favorably with the experimental results of conversion and MWD at varying monomer fe…
