Sur le discours méta-traductif de la traductologie

Abstract: L’auteur rend hommage a l’ampleur et a la diversite de tout ce qu’a accompli Andre Clas, en soulignant l’importance qu’y revet la traduction, et notamment son travail editorial a la direction de la revue Meta. Puis il thematise quatre approches methodologiques fondamentales en traductologie : prescriptive ou normative, descriptive, inductive ou scientifique et productive (orientee vers la pratique). Il critique les contrastivistes, qui ne s’interessent a la traduction que dans la perspective d’une comparaison entre les langues, leur opposant les veritables traductologues, qui prennent pour objet la realite de la pratique traduisante. Enfin il reprend, sur de nouveaux frais, l’immemoriale question du litteralisme en traduction, aux termes de laquelle s’opposent sourciers et ciblistes.

Neoliberalismo: neo-imperialismo

Abstract: Neoliberalism is a new phase of capitalism which was asserted at the beginning of the 1980s. Considering its more general features as in the United States and Europe, it can be characterized by: a more favorable dynamic of technical change and profitability, the creation of income flows to the benefit of the most accommodated classes of the population, and diminished rates of accumulation. A central feature of imperialism in the neoliberal era is U.S. hegemony, a country which is draining huge flows of income from the rest of the world. This domination is, however, undermined by increasing external disequilibria, the expression of an extraordinary wave of consumption from households.

Petri Nets Repository: A Tool to Benchmark and Debug Petri Net Tools

Abstract: For a given scientific community, being able to use a common and rich accepted benchmark for the evaluation of algorithms and prototypes is an added value. The goal of this paper is to present Petri Nets Repository, an open Petri nets models database. It offers two main ways to navigate through the benchmark using criteria related to Petri net properties: a Web interface, and a Web service API (REST). So far, this database embeds the models from the Model Checking Contest, as well as those of the discontinued Petriweb.

Effect of aging on the coordination between equilibrium and movement: what changes?

Abstract: This investigation studies the effect of aging on the coordination between equilibrium and trunk movement. Eight young adults and seven adults at the end of middle age bent their trunk forward and stabilized their position. The center of mass shift was studied as an indicator of equilibrium control as was the electromyographic pattern of the main muscles involved in the movement. The kinematic strategy responsible for both the movement and equilibrium control was quantified by performing a principal components analysis on the hip, knee, ankle angle changes occurring during the movement. We observed that the effect of aging can be detected early. It is not expressed as a deterioration of equilibrium control but rather as "over control". The kinematic strategy is modified, the central command adapted. These results could express the onset of a lesser ability to simplify the coordination between equilibrium and movement as young adults leading to its deterioration in the elderly.

A quasi-3D finite element model for the analysis of thin-walled beams under axial–flexural–torsional loads

Abstract: A quasi-3D finite element model (FEM) with a low computational cost is presented for coupled bending and torsional–warping analysis of thin-walled beams. The presented FEM converts the problem of 3D analysis of thin-walled beams into separated 2D cross-sectional and 1D modeling. The warping function over the cross-section of the thin-walled beams is firstly approximated, via a 2D FEM. Then, a 1D FEM is developed for computing the axial variations of the displacement field variables. For describing the kinematic of the thin-walled beam due to axial extension and bending, the concept of hypothetical equivalent layered composite cross-section (HELCS) is employed. Using the HELCS, the non-classical effects like transverse shear flexibility can be easily incorporated into the formulation. A refined sinus theory is employed to describe the displacement fields of the equivalent layered cross-section. In contrast to other refined models of literature, the present model does not require the calculation of any geometric, torsional and warping constants. For validation of the proposed model, comparisons are made with the results of 2D/3D finite element analysis as well as the numerical and analytical results reported by other researchers. The proposed model not only gives accurate results but also reduces the number of involved degrees-of-freedom (DOFs) significantly. Considering the effects of the restrained warping due to torsion, no need to use the shear correction factor, satisfaction of zero-conditions of shear stresses on the exterior surfaces of beams are other advantages of the proposed FEM.
