Ce mémoire s’intéresse aux apports possibles de la biomécanique meyerholdienne à l’expression théâtrale et plastique du slam de poésie, l’objectif initial de la recherche consistant à bonifier et à développer l’expression tant gestuelle que vocale du poète performant son texte à slamer. Il s’agissait donc, à travers le processus de recherche-création proposé, de conduire une série de laboratoires et d’expérimentations théâtrales afin de développer Panpan!, un spectacle expérimental hybridant à la fois biomécanique et slam de poésie. Des multiples expériences nécessaires à la réalisation de ce court spectacle, j’ai dégagé une série d’outils théoriques et pratiques, que j’ai ensuite exposés en profondeur dans cet essai. En annexe, le lecteur trouvera également l’ensemble de mes outils de travail, développés au fil de ma pratique expérimentale et ayant permis tant la réalisation de Panpan! que la découverte et l’étude des principes théoriques et pratiques dont fait état ma recherche. Mots clés: poésie slamée, slam de poésie, biomécanique, Vsevolod E. Meyerhold, slam-théâtre, expression corporelle, expression vocale, partition dramaturgique, mécanique dramaturgique, musicalité, virtuosité, rythme, constructivisme russe, grotesque, cabotinage.

Introducción: El trabajador avícola presenta un alto riesgo de sufrir de Desórdenes Musculo esqueléticos, debido a la realización de trabajos manuales repetitivos; posición bípeda prolongada, posturas por fuera de ángulos de confort de miembros superiores Objetivo: Establecer las recomendaciones basadas en la evidencia de las intervenciones en salud para los Desórdenes Musculoesqueléticos (DME) en el trabajador avícola. Metodología: Se realizó una revisión de la literatura de los estudios primarios publicados en las bases de datos Medline, Scient Direct y Scielo desde 1990. Los artículos se clasificaron de acuerdo con: el tipo de estudio, la calidad de éste y el nivel de evidencia que aportaba. Resultados: Dentro de las recomendaciones de la evidencia disponible para el manejo integral de los pacientes de la industria avícola con riesgos o eventos asociados a DME se encuentran las siguientes: 1) incorporar un enfoque sistémico en la atención a dichos trabajadores, 2) incluir aspectos psicosociales en la identificación y explicación de los riesgos y eventos en salud, 3) permitir los descansos, microrupturas y pautas para el ejercicio, 4) facilitar la rotación y ampliación de puestos de trabajo, 5) mejorar las herramientas de trabajo - especialmente el corte de los cuchillos. Conclusiones: Las intervenciones descritas en la presente revisión, apuntan hacia el mejoramiento de la incidencia y la prevalencia de los DMS, la disminución de incapacidad temporal y definitiva por los DMS, el mejoramiento en la producción industrial y la reducción de costos tanto económicos como humanos. Sin embargo, se debe plantear la necesidad de continuar impulsando el desarrollo de investigaciones y estudios que permitan tener mayores elementos de juicio para poder realizar recomendaciones a los tipos de intervenciones propuestas. A pesar de lo anterior, las intervenciones en salud para los trabajadores de la industria avícola deben ser enfocadas desde la prestación integral de los servicios de salud.

The processing map for hot working of Al alloy 2014-20vol.%Al2O3 particulate-reinforced cast-plus-extruded composite material has been generated covering the temperature range 300-500 degrees C and the strain rate range 0.001-10 s(-1) based on the dynamic materials model. The efficiency eta of power dissipation given by 2m/(m + 1), where m is the strain rate sensitivity, is plotted as a function of temperature and strain rate to obtain a processing map. A domain of superplasticity has been identified, with a peak efficiency of 62% occurring at 500 degrees C and 0.001 s(-1). The characteristics of this domain have been studied with the help of microstructural evaluation and hot-ductility measurements. Microstructural instability is predicted at higher strain rates above (ls(-1)) and lower temperatures (less than 350 degrees C).

The two main forces affecting economic development are the ongoing technological revolution and the challenge of sustainability. Technological change is altering patterns of production, consumption and behaviour in societies; at the same time, it is becoming increasingly difficult to ensure the sustainability of these new patterns because of the constraints resulting from the negative externalities generated by economic growth and, in many cases, by technical progress itself. Reorienting innovation towards reducing or, if possible, reversing the effects of these externalities could create the conditions for synergies between the two processes. Views on the subject vary widely: while some maintain that these synergies can easily be created if growth follows an environmentally friendly model, summarized in the concept of green growth, others argue that production and consumption patterns are changing too slowly and that any technological fix will come too late. These considerations apply to hard technologies, essentially those used in production. The present document explores the opportunities being opened up by new ones, basically information and communication technologies, in terms of increasing the effectiveness (outcomes) and efficiency (relative costs) of soft technologies that can improve the way environmental issues are handled in business management and in public policy formulation and implementation.

Summary. Negotiating in the Council of the European Union poses some challenges that are common to most international negotiations but there are other dimensions that are a lot more specific. In order to understand better the specific nature of negotiations on a European level and to develop some practical guidelines for European negotiators, it is important to situate European negotiations in the more general context of the theory on international relations and to remember that European negotiations are governed by the general principles which characterise the negotiation theory. This working document has three objectives; after having reminded ourselves of the fundamental principles that govern European negotiations, it aims to provide a general foundation, which in turn will be useful for preparing most negotiations within the Council. A series of practical recommendations will then be made in order to contribute to the strategic thinking of the negotiator responsible for defending the interests of his or her Member State within the Council.

This paper completes the comparative analysis of the investment demand behaviour, of a sample of specialised arable crop farms, for farm buildings and machinery and equipment, as a function of the different types and levels of Common Agricultural Policy support, in selected European Union Member States. This contribution focuses on their quantitative interdependence calculating the relevant elasticity measures. In turn, they constitute the methodological tool to simulate the percentage expected change in average net investment levels associated to the implementation of the, recently proposed and currently under discussion, reductions in the Pillar I Direct Payments disbursed under the Common Agricultural Policy. Evidence suggests a statistically significant elastic and inelastic relationship between both types of subsidies and the investment levels for both asset classes in Germany and Italy, respectively. An elastic dependence of investment in farm buildings on decoupled subsidies exists in Hungary while changes in the level of coupled payments appear to translate into less than proportional changes in the demand for both farm buildings and machinery and equipment in France. Coupled payments appear to influence the UK demand for both asset classes in an elastic manner while decoupled support seems to induce a similar effect on investment in machinery and equipment. Since the currently discussed Common Agricultural Policy reform options imply, almost exclusively, a reduction in the level of support granted through Direct Payments, simulated effects were expected to reveal a worsening of the farm investment prospects for both asset types (i.e., a larger negative investment or a smaller positive one). The actual evidence largely respects this expectation with the sole exception of investment in machinery and equipment in France and Italy reaching smaller negative or larger positive levels irrespectively of the magnitude of the implemented cuts in Direct Payments.
