La langue et l’extrême dans la version théâtrale de Se questo è un uomo de Primo Levi

Dans l’adaptation théâtrale de son récit Se questo è un uomo, Primo Levi ne crée pas un langage de l’extrême avec le spectacle des corps suppliciés et des râles de la souffrance. C’est au contraire une véritable stratégie de l’énonciation, du dialogue et de la langue qu’il met en oeuvre. En effet, sur scène, la première personne du récit est diffractée en plusieurs instances locutrices (un personnage d’auteur, un choeur, un déporté) ; le dialogue et la communication entre les déportés déploient, en direction du destinataire-spectateur, une fonction beaucoup plus heuristique qu’émotionnelle, et le babélisme provoqué par toutes les langues maternelles présentes à Auschwitz exprime le désir de préservation de l’humanité. De sorte que dans cette version dramatique, la langue de l’extrême entretient un rapport d’intelligence avec le destinataire-spectateur, tout en valorisant les éclats d’humanité des déportés.In the theatrical adaptation of his narrative Se questo è un uomo [If this is a man], Primo Levi does not create a language of the extreme through the spectacle of tortured bodies and groans of suffering. Instead, he brings into play a veritable strategy of enunciation, dialogue and language. Indeed, on stage, the story’s first person narrator is diffracted into several narrative authorities (an author, a choir, a deported individual); dialogue and communication among the deported deploy, for the sake of the addressee-spectator, a function that is much more heuristic than emotional, and the babel of voices triggered by all the mother tongues present at Auschwitz expresses a desire for the preservation of humanity. So it is that in this dramatic version, the language of the extreme maintains a rapport of intelligence with the addressee-spectator, while enhancing the sparks of humanity in and by the deported

Dynamical effects induced by long range activation in a nonequilibrium reaction-diffusion system

We both show experimentally and numerically that the time scales separation introduced by long range activation can induce oscillations and excitability in nonequilibrium reaction-diffusion systems that would otherwise only exhibit bistability. Namely, we show that the Chlorite-Tetrathionate reaction, where autocatalytic species diffuses faster than the substrates, the spatial bistability domain in the nonequilibrium phase diagram is extended with oscillatory and excitability domains. A simple model and a more realistic model qualitatively account for the observed behavior. The latter model provides quantitative agreement with the experiments.Comment: 19 pages + 9 figure

Turing Instability in a Boundary-fed System

The formation of localized structures in the chlorine dioxide-idodine-malonic acid (CDIMA) reaction-diffusion system is investigated numerically using a realistic model of this system. We analyze the one-dimensional patterns formed along the gradients imposed by boundary feeds, and study their linear stability to symmetry-breaking perturbations (Turing instability) in the plane transverse to these gradients. We establish that an often-invoked simple local linear analysis which neglects longitudinal diffusion is inappropriate for predicting the linear stability of these patterns. Using a fully nonuniform analysis, we investigate the structure of the patterns formed along the gradients and their stability to transverse Turing pattern formation as a function of the values of two control parameters: the malonic acid feed concentration and the size of the reactor in the dimension along the gradients. The results from this investigation are compared with existing experiments.Comment: 41 pages, 18 figures, to be published in Physical Review

Domain Structures in Fourth-Order Phase and Ginzburg-Landau Equations

In pattern-forming systems, competition between patterns with different wave numbers can lead to domain structures, which consist of regions with differing wave numbers separated by domain walls. For domain structures well above threshold we employ the appropriate phase equation and obtain detailed qualitative agreement with recent experiments. Close to threshold a fourth-order Ginzburg-Landau equation is used which describes a steady bifurcation in systems with two competing critical wave numbers. The existence and stability regime of domain structures is found to be very intricate due to interactions with other modes. In contrast to the phase equation the Ginzburg-Landau equation allows a spatially oscillatory interaction of the domain walls. Thus, close to threshold domain structures need not undergo the coarsening dynamics found in the phase equation far above threshold, and can be stable even without phase conservation. We study their regime of stability as a function of their (quantized) length. Domain structures are related to zig-zags in two-dimensional systems. The latter are therefore expected to be stable only when quenched far enough beyond the zig-zag instability.Comment: Submitted to Physica D, 11 pages (RevTeX 3), 12 postscript figure

Pragmatique culturelle et traduction de la comédie de répertoire (du français à l'italien)

ABSTRACTLa traduction de la comédie de répertoire distingue la tendance archaïsante, qui conserve la forme et la culture originelles du texte dans la version L2, et la tendance modernisante, qui, pour satisfaire la communication contemporaine, accommode les différents niveaux du texte au destinataire L2. Dans trois traductions italiennes contemporaines deLe malade imaginaire, on a constaté que l'orientation archaïsante domine. Cependant, l'opposition stricte des deux tendances est fréquemment dépassée, car la traduction de la comédie veut surtout conserver ses effets pragmatiques sur le spectateur. Il n'est donc pas rare que le texte traduit mélange les procédés indépendamment de son orientation générale.</jats:p
