Investigación acción participativa y compromiso social del arquitecto: estudio de un caso

Presentamos la Investigación Acción Participativa (IAP) que hemos llevado a cabo en un barrio de las afueras de Albacete, cuyo nombre popular, “las 500”, evidencia su condición marginal (perfil social, patologías constructivas, viviendas mínimas) de polígono de vivienda social promovido por la Obra Sindical del Hogar en los primeros 60. Ha consistido en aprovechar la oportunidad que nos brindaba la inauguración de su nueva iglesia para buscar la documentación y estudiar la arquitectura y el urbanismo del barrio, permitiendo su conocimiento y su valoración para darlo a conocer y a valorar y para irlo mejorando. La acción principal se ha concretado en una exposición itinerante que conmemora su 50 aniversario.

Salud comunitaria y acción social en el control epidemiológico del tracoma infantil, España (1932-1939)

En el contexto de la endemia tracomatosa que afectó a diversas regiones españolas hasta la década de 1960, se analizan los determinantes epidemiológicos del tracoma infantil y su abordaje desde el modelo de asistencia preventiva que encerraba el concepto de salud comunitaria que se perfiló en el período de entreguerras. La detección precoz de casos, unida a actividades preventivas, educativas, terapéuticas y de inspección, como las que llevaron a cabo las enfermeras visitadoras, contribuyeron al control de la enfermedad. Los resultados reafirman la validez de las estrategias de intervención horizontal de mejora de las condiciones higiénicas y de los factores medioambientales que explicaban la prevalencia del tracoma.

Impacto y consecuencias sociales contemporáneas de las políticas de tutela estatal en las reservas indígenas canadienses

Este artículo tiene como objetivo examinar el impacto y las consecuencias sociales contemporáneas del mantenimiento del sistema de organización social denominado «reserva indígena» en Canadá. Mediante un estudio de caso, se explora cómo la política organizacional y la estructura institucional contemporánea en las reservas indígenas canadienses están alimentando problemas psicosociales y de salud mental como, por ejemplo, abuso de sustancias psicoactivas, depresión, negligencia parental o violencia doméstica. Tres características estructurales se identifican como problemas inherentes en la estructura organizacional de las reservas contemporáneas: el desempleo estructural, la dependencia de programas de asistencia social y el faccionalismo comunitario.

The relevance of harmonising the technical level of social housing with the urban level of the neighbourhood through the example of the 500 dwellings in Albacete

The Architecture and Household Trade Union built nearly 2,000 subsidized dwellings in Albacete from 1941 to 1971. It was the responsible entity from the end of the Civil War until the beginning of Democracy of the social policy programs in Spain. Later on, and together with the National Housing Institute, were responsible for the construction activity. Its limited budget, scarcity of technical and human resources and an urgent need for new housing developments, constituted the basis for producing a vast housing market of low construction qualities. However, thanks to the true architectonic expertise of some of the professionals, some of the developments were designed with a clear urban strategy and in direct relation with the city, which characterizes them to be studied and conserved. This is the case for the selected development for the analysis, the urban complex of the 500 dwellings in Albacete, the Hermanos Falcó Neighborhood. Designed and built between 1963, Alfonso Crespo and Adolfo Gil architects, and 1977 second reformed project by the architect Fernando Rodríguez. It is characterized by its layout on the territory, its controlled relation with the city and its different types of open blocks. Above all, its spatial and human scale strengths, directly related to the European post-war proposals, have to be emphasized; although its technical deficiencies affect the interior quality of the houses. This paper examines its virtues and failures and proposes, using current tools, its renovation. This proposal main aims are to extend its lifetime and develop the particular and urban sustainability levels.

Culture and World Vision: The Cognitive Mythical Mode

Culture is the system of knowledge, from whose meanings the human being screened and selected their understanding of Reality in the broad sense, and interprets and regulates the facts and data of social behavior. In this sense, culture is a program for social action and acting in humans during the process of socialization and social interaction. The meanings of each culture are the cumulative product of collective and individual thinking, in ecological economic, social and political specific situations, so are the expression of each particular cultural historical conjuncture. Moreover, the universal cognitive structure for the apprehension of cultural reality is the World Vision (WV). Due to its importance and significance as substratum of religious and political belief systems, we will gird our study to mythical cognitive mode or mythical WV.

The genus Callistethus (Coleoptera: Scarabaeidae: Rutelinae) in the Neotropics: new data and new species from Costa Rica

The species Callistethus carbo sp.n., C. flavodorsalis sp.n., C. fuscorubens sp.n., C. lativittis sp.n., C. levigatus sp.n., C. macroxantholeus sp.n., C. microxantholeus sp.n., C. multiplicatus sp.n., C. parapulcher sp.n., C. pseudocollaris sp.n. and C. stannibractea sp.n. from Costa Rica are described. Synonymy of Callistethus kolbei (Ohaus, 1897) with Callistethus specularis (Bates, 1888) is proposed. A phylogenetic analysis based on the genes 16S, COI and 28S is carried out for Costa Rican species and diagnostic morphological features for the genus are tested on it for phylogenetic signal. An identification key for Callistethus species of Costa Rica is provided. The distribution patterns of Callistethus species in Costa Rica are discussed.

Paving the way for methane hydrate formation on metal–organic frameworks (MOFs)

The presence of a highly tunable porous structure and surface chemistry makes metal–organic framework (MOF) materials excellent candidates for artificial methane hydrate formation under mild temperature and pressure conditions (2 °C and 3–5 MPa). Experimental results using MOFs with a different pore structure and chemical nature (MIL-100 (Fe) and ZIF-8) clearly show that the water–framework interactions play a crucial role in defining the extent and nature of the gas hydrates formed. Whereas the hydrophobic MOF promotes methane hydrate formation with a high yield, the hydrophilic one does not. The formation of these methane hydrates on MOFs has been identified for the first time using inelastic neutron scattering (INS) and synchrotron X-ray powder diffraction (SXRPD). The results described in this work pave the way towards the design of new MOF structures able to promote artificial methane hydrate formation upon request (confined or non-confined) and under milder conditions than in nature.
