El objetivo es mostrar a los alumnos de E.S.O. la importancia de conocer la lengua inglesa para su desarrollo personal y su futuro profesional a través de un ejemplo de multiculturalidad concreto: Londres. Como principal objetivo, se perseguía, promover en los alumnos actitudes de tolerancia y respeto hacia otras culturas, otras gentes, otras formas de pensamiento, el medio ambiente, la salud y los hábitos sanos de consumo, a través del conocimiento de los mismos; así como dar a conocer la importancia de la lengua inglesa y su cultura, a través de distintos ámbitos como trabajo, ocio y comunicación. Se puede decir que la evaluación de la consecución de objetivos, es a nuestro criterio como coordinadoras del proyecto, la siguiente: 1. Los alumnos han trabajado de forma satisfactoria el objetivo de respeto y tolerancia hacia todos aquellos aspectos de la vida que fueron considerados importantes en el proyecto. 2. Los alumnos han reconocido que el ingles es una lengua que se usa en todo el mundo, bien como primera o como segunda lengua. 3. Han trabajado situaciones de comunicación en lengua inglesa, tratando los ámbitos de trabajo, ocio y cultura. 4. El proyecto se atuvo al objetivo de atención a la diversidad dentro del aula, trabajando, después de la primera evaluación, en distintos niveles organizados (alto, medio y bajo) de los alumnos participantes.

El presente documento recoge los textos creados, tanto por ni??osy ni??as como por mayores, para el Taller Intergeneracional Art??stico-Literario organizado por la Concejal??a de la Infancia del Ayuntamiento de Coslada (Madrid). La experiencia tuvo como base el inter??s de que esas generaciones dejen de ser independientes entre si y constituyan una parte activa de la vida social. La cooperaci??n y la creatividad fueron los soportes sobre los que se sustent?? esta idea.

This paper deals with second-generation, one-and-a-half generation and ‘‘prolonged sojourner” Trinidadian transnational migrants, who have decided to ‘return’ to the birthplace of their parents. Based on 40 in-depth interviews, the paper considers both the positive and critical things that these youthful transnational migrants report about returning to, and living in, this multi-ethnic plural society and the salience of racial and colour-class stratification as part of their return migration experiences. Our qualitative analysis is based on the narratives provided by these youthful returnees, as relayed ‘‘in their own words”, presenting critical reflections on racism, racial identities and experiences as transnational Trinidadians. It is clear that it is contexts such as contemporary working environments, family and community that act as the reference points for the adaptation ‘‘back home” of this strongly middle-class cohort. We accordingly encounter a diverse, sometimes contesting set of racial issues that emerge as salient concerns for these returnees. The consensus is that matters racial remain as formidable legacies in the hierarchical stratification of Trinidadian society for a sizeable number. Many of our respondents reported the positive aspects of racial affirmation on return. But for another sub-set, the fact that multi-ethnic and multi-cultural mixing are proudly embraced in Trinidad meant that it was felt that return experiences were not overly hindered, or blighted by obstacles of race and colour-class. For these returnees, Trinidad and Tobago is seen as representing a 21st century ‘‘Melting Pot”. But for others the continued existence of racial divisions within society – between ethnic groups and among those of different skin shades – was lamented. In the views of these respondents, too much racial power is still ascribed to ‘near-whiteness’. But for the most part, the returnees felt that where race played a part in their new lives, this generally served to advantage them. However, although the situation in Trinidad appears to have been moderated by assumptions that it remains a racial ‘Melting Pot’, the analysis strongly suggests that the colour-class system of stratification is still playing an essential role, along with racial stereotyping in society at large.

The confined crystallization of poly(ethylene oxide) (PEO) in predominantly spherical microdomains formed by several diblock copolymers was studied and compared. Two polybutadiene-b-poly(ethylene oxide) diblock copolymers were prepared by sequential anionic polymerization (with approximately 90 and 80 wt % polybutadiene (PB)). These were compared to equivalent samples after catalytic hydrogenation that produced double crystalline polyethylene-b-poly(ethylene oxide) diblock copolymers. Both systems are segregated into microdomains as indicated by small-angle X-ray scattering (SAXS) experiments performed in the melt and at lower temperatures. However, the PB-b-PEO systems exhibited a higher degree of order in the melt. A predominantly spherical morphology of PEO in a PB or a PE matrix was observed by both SAXS and transmission electron microscopy, although a possibly mixed morphology (spheres and cylinders) was formed when the PEO composition was close to the cylinder-sphere domain transitional composition as indicated by SAXS. Differential scanning calorimetry experiments showed that a fractionated crystallization process for the PEO occurred in all samples, indicating that the PE cannot nucleate PEO in these diblock copolymers. A novel result was the observation of a subsequent fractionated melting that reflected the crystallization process. Sequential isothermal crystallization experiments allowed us to thermally separate at least three different crystallization and melting peaks for the PEO microdomains. The lowest melting point fraction was the most important in terms of quantity and corresponded to the crystallization of isolated PEO spheres (or cylinders) that were either superficially or homogeneously nucleated. This was confirmed by Avrami index values of approximately 1. The isothermal crystallization results indicate that the PE matrix restricts the crystallization of the covalently bonded PEO to a higher degree compared to PB.
