Dialética da pratica e ação sem prática

O conceito de prática recobriria o de sistema de ação, não fosse a existência de sistemas de ação sem prática. Resta que uma prática é um sistema de ação. Como conseqüência, suposta a reciprocação de sistema com teoria e uma atenta inspeção nos termos da proposição, há equivalência semântica entre prática teóricae sistema de ação prático. Num e noutro caso, a contradição interna aos pares de conceitos se resolve dialeticamente. Graças à dialética, são fundidos numa unidade de sentido, síntese de tensões opostas. Daí a proposta de uma dialética da prática global, conjuntamente abstrata e histórica. Destotalizada ou à margem dessa dialética, pode ser destacada a ação sem prática, exemplificada no drama. Dramática é precisamente uma ação que não é prática. O tempo e o lugar da prática são a história e o mundo do homem; o tempo e o lugar do drama são a ficção cultural e a substância simbólica. Mimese da prática, o drama, reproduz, não os traços do modelo, mas a sua produção, tornando-se por sua vez modelo do modelo. Mimese não é cópia, é forma autônoma de eficiência, paradoxalmente sem prática mas especular.

Sostenibilidad en el sector de la construcción. Sostenibilidad en estructuras y puentes ferroviarios

La escasez de recursos, el cambio climático, la pobreza y el subdesarrollo, los desastres naturales, son solo algunos de los grandes retos a que se enfrenta la humanidad y a los que la economía verde y el desarrollo sostenible tienen que dar respuesta. El concepto sostenible surge a raíz de la necesidad de lograr en todas las actividades humanas un nuevo equilibrio con el medioambiente, la sociedad y la economía, es decir un desarrollo más sostenible. La construcción supone en este nuevo concepto un sector básico, con grandes impactos en los recursos, los residuos, las emisiones, la biodiversidad, el paisaje, las necesidades sociales, la integración, el desarrollo económico del entorno, etc. Es por ello, que la construcción sostenible tiene una importancia esencial como demuestra su amplia aplicación teórica y práctica ya en proyectos de planificación urbana y de edificación. En la ingeniería civil estas aproximaciones son todavía mínimas, aunque ya se están considerando ciertos criterios de sostenibilidad en proyectos de construcción. La construcción consume muchos recursos naturales, económicos y tiene gran incidencia social. En la actualidad su actividad consume un 30% de los recursos extraídos de la tierra y la energía, y en consecuencia genera el 30% de los gases de efecto invernadero y residuos sólidos del mundo (EEA, 2014). Este impacto debería suponer una gran responsabilidad para los profesionales y gobiernos que toman cada día las decisiones de diseño e inversión en la construcción, y su máxima eficiencia debería estar muy presente entre los objetivos. En esta tesis doctoral se plantea un nuevo modelo para la evaluación de la sostenibilidad en los proyectos mediante un sistema de indicadores, basados en las áreas de estudio de las certificaciones de sostenibilidad existentes y en un análisis multi-criterio de cada uno de los axiomas de la sostenibilidad. Como reto principal se marca la propuesta de una metodología que permita identificar, priorizar y seleccionar los indicadores y las variables más importantes de lo que es considerado como una construcción sostenible en el caso de infraestructuras ferroviarias, más concretamente en puentes ferroviarios, y que además sirva para priorizar nuevos proyectos que se adapten a los nuevos objetivos del desarrollo sostenible: el respeto al medioambiente, la integración social y la económica. El objetivo es la aplicación de estos indicadores desde las etapas más tempranas del proyecto: planificación, diseño de alternativas y selección de alternativas. Para ello, en primer lugar, se ha realizado un análisis en profundidad de los distintas organizaciones de certificación de la sostenibilidad mundiales y se ha desarrollado una comparativa entre ellas, detallando el funcionamiento de las más extendidas (BREEAM, LEED, VERDE, DGNB). Tras esto, se ha analizado la herramienta matemática MIVES de análisis multi-criterio para su aplicación, en la tesis, a las infraestructuras ferroviarias. En la segunda parte se desarrolla para las estructuras ferroviarias un nuevo modelo de indicadores, un sistema de ayuda a la decisión multi-criterio basado en los tres axiomas de las sostenibilidad (sociedad, medioambiente y economía), articulados en un árbol de requerimientos inspirado en el método MIVES, que propone una metodología para el caso de las infraestructuras ferroviarias. La metodología MIVES estructura el proceso de decisión en tres ramas: Requisitos, componentes y ciclo de vida. Estas ramas definen los límites de los sistemas. El eje de los requisitos del árbol de los requisitos o se estructura en tres niveles que corresponden al requisito específico: criterios e indicadores. Además, es necesario definen la función del valor para cada indicador, definen el peso de importancia de cada elemento del árbol y finalmente con el calcular el valor de cada alternativa selecciona el mejor de él. La generación de este árbol de requerimientos en estructuras ferroviarias y la medición de los parámetro es original para este tipo de estructuras. Por último, tras el desarrollo de la metodología, se ha aplicado la propuesta metodológica mediante la implementación práctica, utilizando el método propuesto con 2 puentes ferroviarios existentes. Los resultados han mostrado que la herramienta es capaz de establecer una ordenación de las actuaciones coherente y suficientemente discriminante como para que el decisor no tenga dudas cuando deba tomar la decisión. Esta fase, es una de las grandes aportaciones de la tesis, ya que permite diferenciar los pesos obtenidos en cada una de las áreas de estudio y donde la toma de decisión puede variar dependiendo de las necesidades del decisor, la ubicación del puente de estudio etc. ABSTRACT Scarce resources, climate change, poverty and underdevelopment, natural disasters are just some of the great challenges facing humanity and to which the green economy will have to respond. The sustainable concept arises from the need for all human activities in a new equilibrium with the environment, society and the economy, which is known as sustainable development. The construction industry is part of this concept, because of its major impacts on resources, waste, emissions, biodiversity, landscape, social needs, integration, economical development, environment, etc. Therefore, sustainable construction has a critical importance as already demonstrated by its wide application and theoretical practice in urban planning and building projects. In civil engineering, these approaches are still minimal, although some criteria are already taken into account for sustainability in infrastructure projects. The construction industry requires a lot of natural resources, has a real economic relevance and a huge social impact. Currently, it consumes 40% of produced power as well as natural resources extracted from the earth and thus leads to an environmental impact of 40% regarding greenhouse gas emissions and solid wastes (EEA 2014). These repercussions should highly concern our governments and professional of this industry on the decisions they take regarding investments and designs. They must be inflexible in order to ensure that the main concern has to be a maximum efficiency. Major events like the COP21 held in Paris in December 2015 are a concrete signal of the worldwide awareness of the huge impact of each industry on climate. In this doctoral thesis a new model for the evaluation of the sustainability in the projects by means of a system of indicators, based on the areas of study of the existing certifications of sustainability and on an analysis considers multi-criterion of each one of the axioms of the sustainability. The primary aim of this thesis is to study the mode of application of sustainability in projects through a system of indicators. . The main challenge consists of create a methodology suitable to identify, prioritize and select the most important indicators which define if a building is sustainable in the specific case of railway infrastructures. The methodology will help to adapt future projects to the new goals of sustainable development which are respect of nature, social integration and economic relevance. A crucial point is the consideration of these indicators from the very beginning steps of the projects: planning, design and alternatives reflections. First of all, a complete inventory of all world energy certification organizations has been made in order to compare the most representative ones regarding their way of functioning (BREEAM, LEED, VERDE, DGNB). After this, mathematical tool MIVES of analysis has been analyzed multi-criterion for its application, in the thesis, to railway infrastructures. The second part of the thesis is aimed to develop a new model of indicators, inspired by the MIVES method, consisting in a decision-making system based on the 3 foundations of sustainability: nature impact, social concerns, and economic relevance. The methodology MIVES structures the decision process in three axes: Requirements, components and life cycle. These axes define the boundaries of the systems. The axis of requirements o tree requirements is structured in three levels corresponding to specific requirement: criteria and indicators. In addition, is necessary define the value function for each indicator, define the weight of importance of each element of the tree and finally with the calculate the value of each alternative select the best of them. The generation of this tree requirements in railway structures and measuring the parameter is original for this type of structures. Finally, after the development of the methodology, it has validated the methodology through practical implementation, applying the proposed method 2 existing railway bridges. The results showed that the tool is able to establish a coherent management of performances and discriminating enough so that the decision maker should not have doubts when making the decision. This phase, is one of the great contributions of the thesis, since it allows to differentiate the weights obtained in each one from the study areas and where the decision making can vary depending on the necessities of the decisor, the location of the bridge of study etc.

Althusserianismo e luta armada na Argentina : A experiência do Zaratismo

One of the most important spaces into which Althusserianism diffused in Argentina was Zaratismo, a political tendency that spread from the Communist Party to an armed organization called the Argentinian Liberation Forces. In this work we propose an analysis of this experience that emphasizes the relations between the characteristic elements of Althusserianism - the epistemological break in Marx's work, theoretical practice, and the concept of economic and social formation - and those of the development of an armed strategy for Argentina, including critiques of theoreticism and opportunism, an adaptation of the theory of war to the national situation, and a correct conjunction of theoretical concepts with concrete realitie

Materialismo, ideología y juegos de lenguaje

La discusión sobre las consecuencias políticas del pensamiento de L. Wittgenstein ha girado sobre la posibilidad de construir miradas críticas sobre lo social, su legitimidad, amplitud, fuerza, etc. Sin embargo, aproximar a Wittgenstein a una posición materialista, como la entendía L. Althusser, conduce a una comprensión diferente de la crítica, vinculada a la tarea de deconstruir el discurso filosófico que intenta unificar y organizar jerárquicamente las evidencias (certezas) constitutivas de los diferentes juegos de lenguaje en los que se despliega lo social. Se intenta extraer de esta aproximación una distinción entre la filosofía como práctica teórica ideológica y como práctica teórica crítica

Le conseil génétique: aspects théoriques et pratique en prénatal [Genetic counselling: theoretical aspects and prenatal practice]

Le conseil génétique doit fournir aux individus une information médicale précise et un soutien psychologique. L'importance des principes d'autonomie et de confidentialité, dogmes du conseil génétique, est renforcée par la nouvelle loi suisse (LAGH). Dans certains pays, une grande partie du conseil génétique est assurée par des conseillers en génétique non médecins ayant une formation postgraduée spécifique. Le conseil génétique joue un rôle grandissant dans différents domaines de la médecine. En particulier, il est indispensable dans le contexte du prénatal où les couples reçoivent des informations complexes et doivent bénéficier d’un soutien pour prendre une décision. Genetic counselling provides families with accurate medical information and psychological support. Respect and concern for the emotional well-being should be taken into account while discussing genetics aspects and recurrence risks. The importance of autonomy and confidentiality, central to genetic counselling, is reinforced by the new Swiss law (LAGH). In many countries, most of the genetic counselling is provided by genetic counsellors who have a specialised post-graduate training. Genetic counselling plays an increasing role in different medical specialities. In particular, it is essential in the context of prenatal and pre-conceptual care, where couples are confronted to complex information and should have access to appropriate support during the decision-making process

Reflective practice among MATESOL graduates in the UAE: theoretical construct or ongoing benefit?

Many teacher training programs, including the MATESOL program at the American University of Sharjah (AUS) in United Arab Emirates, encourage their trainees to reflect on their practice. However, whether or not reflection becomes a part of the trainees’ practice once they leave these programs is a thought-provoking question, which formed the core of the current study. The study was qualitative in nature, using interviewing as its method of data collection. The researcher conducted semi-structured interviews with four AUS MATESOL program graduates, and investigated their perceptions of and engagement with reflective practice. The findings of the study indicate that the participants have generally developed an understanding of and appreciation for reflection and reflective practice, are aware of its values, and use different forms of reflection in order to reflect on their practice. However, some of them hold some uncertainties and misconceptions about reflective practice and its different aspects.
