A construção da memória sobre o acidente do césio-137 em Goiânia através da cobertura midiática nos jornais Correio do Povo e Zero Hora em 1987
No full textEste trabalho analisa a construção da memória coletiva sobre o acidente radiológico com o césio-137 em Goiânia, ocorrido em 1987, a partir da cobertura jornalística dos jornais Correio do Povo e Zero Hora. A pesquisa buscou compreender através de análises críticas de manchetes e reportagens dos meses de setembro e outubro de 1987, como a mídia impressa contribuiu para moldar as narrativas sociais e históricas sobre o evento nos momentos iniciais de divulgação do acidente, enfatizando as diferenças editoriais e os contextos em que essas publicações estavam inseridas, em um período de transição política e ascendência do neoliberalismo. Por fim, apresenta o debate sobre os impactos neoliberais na construção da memória no acidente, destacando assim os periódicos enquanto meio de poder na disputa dessa memória, destacando a importância de repensar criticamente o papel do jornalismo na preservação e divulgação de fatos históricos.Este trabajo analiza la construcción de la memoria colectiva sobre el accidente radiológico con Cesio-137 en Goiânia, ocurrido en 1987, a partir de la cobertura periodística de los diarios Correio do Povo y Zero Hora. La investigación buscó comprender, a través del análisis crítico de titulares e informes de los meses de septiembre y octubre de 1987, como los medios impresos habrían contribuido para configurar las narrativas sociales e históricas sobre el evento en los momentos iniciales de publicidad del accidente, enfatizando las diferencias editoriales y los contextos en que estas publicaciones estaban insertadas, en un período de transición política y de ascensión del neoliberalismo. Finalmente, presenta el debate sobre los impactos neoliberales en la construcción de la memoria en el accidente, destacando así el periodismo como medio de poder en la disputa por esta memoria, destacando la importancia de repensar críticamente el papel del periodismo en la preservación y difusión de hechos históricos
Representaciones sociales de los paisajes forestales: un estudio de caso en España sobre la relación entre las dinámicas de cambio forestal, el sentido de la propiedad y la gestión sostenible
No full textIn Southwest Europe the forest landscapes are threatened by degradation and abandonment. This research addresses how the different groups of local forest actors in southern Aragon, Spain, perceive, interpret and narrate their forest landscapes. From 30 qualitative interviews, four divergent socio-ecological discourses have been identified reflecting the social representations. It concludes by highlighting the directions in which public policies should be worked to increase the sustainability of forest landscapes and change the current and divergent socio-ecological discourses: revision of the relationships of property and use rights, increase of internal and external knowledge of the forest management and openness to new actors and new forms of interaction based on cooperation and social innovation.Los bosques son paisajes forestales fundamentales amenazados en el Suroeste de Europa por la degradación y el abandono. Esta investigación aborda cómo los diferentes grupos de actores locales involucrados en la gestión forestal de montes privados en el sur de Aragón (España) perciben, interpretan y narran sus paisajes forestales. A partir de 30 entrevistas cualitativas se han identificado cuatro divergentes discursos socioecológicos en los que se plasman las representaciones sociales de los actores. Se concluye destacando las direcciones en las que debería trabajarse en las políticas públicas para incrementar la sostenibilidad de los paisajes forestales y cambiar los actuales y divergentes discursos: revisión de las relaciones de los derechos de propiedad y uso, incremento del conocimiento interno y externo del manejo forestal y estado de los montes, y apertura a nuevos actores y nuevas formas de interacción asentadas en la cooperación y la innovación social
Modeling and simulation of compressible multi-material interface instabilities
No full textThis work was partially funded by the DGA.We aim to simulate the interactions at the material interface of two compressible media. These interactions are modeled by a single fully Eulerian system of conservation laws. The materials differ by their constitutive laws, that can reproduce the mechanical characteristics of fluids or elastic solid. We illustrate the model with simulations of shock waves impinging on undulated interfaces, generating instabilities such as Richtmyer-Meshkov instabilities

Interpretación de anisotropías petrográficas en granitos ornamentales basada en la medida de la velocidad de las ondas P
No full textThe existence of a possible anisotropy, determined by the orientation of any mineral or by microcrack network in granite rock, isn´t easily detected by the naked eye. Five granitic rocks from Galicia (Spain), namely Albero, Gris Alba, Gris Mondariz, Rosa Porriño and Traspielas, were characterized petrographically by means of textural and mineralogical studies, using optical polarizing microscopy, and fractographic studies were carried out under scanning electron microscopy. Longitudinal wave propagation velocity was measured in three orthogonal directions on cubic samples, oriented according to rift surface (known in quarry works like the preferential partition surface visible in the blocks). Vp was measured on dry and water saturated samples. All the dry samples showed an anisotropic behaviour of Vp. Models of microcrack network distribution and possible mineral grain orientation were developed based on the obtained data.La existencia de una posible anisotropía originada por orientación de minerales y/o redes de microfisuración en rocas graníticas no es fácilmente detectable a simple vista. Cinco rocas graníticas de Galicia, denominadas comercialmente Albero, gris Alba, gris Mondariz, rosa Porriño y Traspielas, se caracterizaron petrográficamente, mediante estudios texturales y mineralógicos utilizando microscopía óptica de polarización, realizándose también estudios fractográficos bajo microscopía electrónica de barrido. Se midieron las velocidades de propagación de las ondas longitudinales (Vp) en tres direcciones ortogonales en muestras cúbicas orientadas según el rift (denominado así en cantería como la superficie preferente de partición). Vp se midió en muestras secas y saturadas. Todas las muestras secas mostraron un comportamiento anisótropo de Vp. A partir de los datos obtenidos se han interpretado las redes de distribución de microfisuras y la orientación de minerales
The emotional weight of "I love you" in multilinguals' languages
No full textThe present paper considers the perceived emotional weight of the phrase I love you in multilinguals’ different languages. The sample consists of 1459 adult multilinguals speaking a total of 77 different first languages. They filled out an on-line questionnaire with open and closed questions linked to language behavior and emotions. Feedback on the open question related to perceived emotional weight of the phrase I love you in the multilinguals’ different languages was recoded in three categories: it being strongest in (1) the first language (L1), (2) the first language and a foreign language, and (3) a foreign language (LX).
A majority of speakers felt I love you was strongest in their L1. Participants offered various explanations for their perception. Statistical analyses revealed that the perception of weight of the phrase I love you was associated with self-perceived language dominance, context of acquisition of the L2, age of onset of learning the L2, degree of socialization in the L2, nature of the network of interlocutors in the L2, and self-perceived oral proficiency in the L2

Skilled migration: the perspective of developing countries
No full textThis chapter focuses on the effects of skilled migration on developing countries. We
first present new evidence on the magnitude of the”brain drain” at the international
level. Using a stylized model of education investment in a context of migration, we
then survey the theoretical and empirical brain drain literature in a unified
framework. Finally we use a particular specification of the model to discuss a
number of policy issues from the perspective of developing countries
