Entropy-expansiveness for partially hyperbolic diffeomorphisms

We show that diffeomorphisms with a dominated splitting of the form $E^s\oplus E^c\oplus E^u$, where $E^c$ is a nonhyperbolic central bundle that splits in a dominated way into 1-dimensional subbundles, are entropy-expansive. In particular, they have a principal symbolic extension and equilibrium states.Comment: 15 pages, 1 figur

Social involvement for community development in rural areas of Cuenca, Spain

Community development must be accompanied by a social involvement process which creates functional groups of citizens capable of taking responsibility for their own development. It is important that this process promotes the structuring of all population groups and provides the appropriate institutional and technical support. The present paper addresses these issues based on over 25 years of experience by the Association Instituto de Desarrollo Comunitario de Cuenca in revitalizing rural areas of the Spanish province of Cuenca. This paper analyses the social involvement process encouraged by this association, the relationships between public institutions and local associations, the role of these associations and the difficulties encountered in the rural areas. The long-term perspective of this experience provides some keys which can be used to successfully support the process of social involvement ―such as information on its characteristics and methodological tools―, establish local associations and create sustainable partnerships that foster the growth of leadership within the community development process

The Surgical Infection Society revised guidelines on the management of intra-abdominal infection

Background: Previous evidence-based guidelines on the management of intra-abdominal infection (IAI) were published by the Surgical Infection Society (SIS) in 1992, 2002, and 2010. At the time the most recent guideline was released, the plan was to update the guideline every five years to ensure the timeliness and appropriateness of the recommendations. Methods: Based on the previous guidelines, the task force outlined a number of topics related to the treatment of patients with IAI and then developed key questions on these various topics. All questions were approached using general and specific literature searches, focusing on articles and other information published since 2008. These publications and additional materials published before 2008 were reviewed by the task force as a whole or by individual subgroups as to relevance to individual questions. Recommendations were developed by a process of iterative consensus, with all task force members voting to accept or reject each recommendation. Grading was based on the GRADE (Grades of Recommendation Assessment, Development, and Evaluation) system; the quality of the evidence was graded as high, moderate, or weak, and the strength of the recommendation was graded as strong or weak. Review of the document was performed by members of the SIS who were not on the task force. After responses were made to all critiques, the document was approved as an official guideline of the SIS by the Executive Council. Results: This guideline summarizes the current recommendations developed by the task force on the treatment of patients who have IAI. Evidence-based recommendations have been made regarding risk assessment in individual patients; source control; the timing, selection, and duration of antimicrobial therapy; and suggested approaches to patients who fail initial therapy. Additional recommendations related to the treatment of pediatric patients with IAI have been included. Summary: The current recommendations of the SIS regarding the treatment of patients with IAI are provided in this guideline

Dinamización Para El Desarrollo Comunitario En Territorios Rurales De Cuenca, España

El desarrollo comunitario ha de ir acompañado de un proceso de dinamización social que suscite grupos funcionales de ciudadanos capaces de ser responsables de su propio desarrollo. Es importante que este proceso fomente la estructuración de todos los grupos de población y cuente con un apoyo técnico e institucional apropiado. Para ello es necesario analizar algunos interrogantes en torno a las relaciones entre las instituciones públicas y las asociaciones locales, el papel de estas asociaciones y las dificultades encontradas en los territorios rurales. En este artículo se abordan dichas cuestiones desde la experiencia de más de 25 años de la Asociación Instituto de Desarrollo Comunitario de Cuenca en la dinamización de las zonas rurales de esta provincia española. Desde esta visión de largo plazo se proporcionan algunas claves para acompañar con éxito el proceso de dinamización ?características y herramientas metodológicas?, lograr la motivación de la población, el arraigamiento de las asociaciones locales, y la generación de partenariados sostenibles que fomenten el liderazgo de la comunidad en el proceso de desarrollo
