Bridges between individuals and communities: dialogic participation fueling meaningful social engagement

This article presents the narratives of non-academic women who have made essential contributions to their community, and their own lives as well, drawing on their involvement in an adult school. We discuss how dialogic participation in lifelong learning activities may (or may not) prompt people to become active social agents in their communities. Through dialogic participation ordinary individuals whose voices have been always silenced, become active stakeholders in the community they belong to, making relevant contributions, which improve their own lives and the community as well. Drawing on personal narratives we re-construct the trajectories of these women as active social agents in their communities, looking on them through the lenses of their participation in lifelong learning activities. This evidence illustrates how dialogic adult education may become a way for undeserved groups to become empowered and make real changes in our society

CTE SE-F: Addendum to two articles on masonry structures.

El artículo revisa las diferencias más significativas que existen entre el Eurocódigo 6 - Estructuras de Fábrica, UNE-ENV 1996-1-1 de junio de 1995, y la versión final (noviembre de 2003) del Código Técnico de la Edificación español en el campo de las estructuras de fábrica en sentido lato, haciendo hincapié en los cambios introducidos en el método de cálculo por asimilación a pórticos y en el método simplificado. Las diferencias existentes han llevado a comparar numéricamente los métodos propuestos con otros estudiados en trabajos anteriormente realizados, comparación que se refleja en una serie de gráficos.[Abstract]The article reviews the most significant differences between Eurocode 6 - Design of masonry structures, EN 1996-1-1 June 1995, and the final version (November 2003) of the spanish Building Technical Code in the field of masonry structures broadly, emphasizing the changes in the method calculation by assimilation porches and in the simplified method.

Sodium borohydride-amberlyst-15 (H+): An effective reductor for hindered and unreactive ketones in aprotic solvent

The combination of sodium borohydride and amberlyst-15 (H+) in tetrahydrofurane is a powerful reductor for unreactive ketones. The reduction is fast, high-yielding and the work-up is extremely simple. Ketals, silyl ethers and other organic functions are not disturbed during the reduction.This work was supported by the Spanish DGICYT (PB94-0028).
