ABSTRACT

Antecedentes: Los efectos ocasionados por los fenómenos de origen natural han ido en aumento, agravando la vulnerabilidad de las poblaciones expuestas. Resulta necesario medir la capacidad de resiliencia de la comunidad para hacer frente a este tipo de situaciones adversas. El objetivo del estudio fue la construcción y validación de una escala de autoinforme de resiliencia comunitaria. Método: Los ítems se basaron en la propuesta de Twigg (2007) y Suárez-Ojeda (2001). Para la validación del instrumento se empleó la V de Aiken y el análisis semi-confirmatorio (McDonald, 2005). Se contó con una muestra de 290 participantes con un rango de edad de 18 a 78 años, de los municipios de Jojutla y Yautepec del Estado de Morelos (México). Resultados: Se obtuvo una escala final unidimensional conformada por 16 ítems, consistencia interna Ω = .924. Conclusiones: Esta escala puede ser de utilidad para quienes trabajan en la gestión integral de riesgos de desastres.


Antecedentes: Os efeitos causados por fenômenos naturais vêm aumentando, agravando a vulnerabilidade das populações expostas. É necessário mensurar a capacidade de resiliência da comunidade para lidar com esse tipo de situação adversa. O objetivo do estudo foi a construção e a validação de uma escala de autorrelato de resiliência comunitária. Método: Os itens foram baseados na proposta de Twigg (2007) e Suárez-Ojeda (2001). Para validação do instrumento, utilizou-se o V do AIKEN e a análise semiconfirmatória (McDonald, 2005). A amostra foi de 290 participantes, com faixa etária de 18 a 78 anos, dos municípios de Jojutla e Yautepec do Estado de Morelos (México). Resultados: Obteve-se uma escala final unidimensional composta por 16 itens, consistência interna Ω = 0,924. Conclusões: Esta escala pode ser útil para quem trabalha na gestão integral do risco de desastres.


Background: The effects caused by natural phenomena have been increasing, aggravating the vulnerability of exposed populations. It is necessary to measure the resilience capacity of the community to face this type of adverse situations. The objective of the study was the construction and validation of a self-report scale of community resilience. Method: The items were based on the proposal of Twigg (2007) and Suárez-Ojeda (2001). The AIKEN V and semi-confirmatory analysis (McDonald, 2005) were used to validate the instrument. There was a sample of 290 participants with an age range of 18 to 78 years, from the municipalities of Jojutla and Yautepec in the State of Morelos (Mexico). Results: A final unidimensional scale made up of 16 items was obtained, internal consistency Ω = .924. Conclusions: This scale can be useful for those working in integrated disaster risk management.

ABSTRACT

Resumen Se efectuó una evaluación geomorfológica y de zonas de erosión y sedimentación del sector oeste de la Península, desde punta Banco hasta punta El Mangle, con el fin de determinar aspectos relevantes desde el punto de vista geológico. El estudio se llevo a cabo durante 9 días en enero del 2008, tiempo en el cual, se realizó el estudio geológico, geomorfológico y de zonas de erosión-sedimentación costera, presentándose en este trabajo solamente los resultados relevantes de los últimos dos aspectos. Geomorfológicamente, se reconocen una predominancia de morfologías de origen estructural, y en menor grado de origen marino, fluvial y denudacional. Se definieron cuatro zonas de erosión-sedimentación, zonas de erosión intensa, de erosión moderada a leve, de erosión y sedimentación y zonas de depositación. Los procesos geológicos más importantes son los deslizamientos, la erosión costera y la alta sismicidad del área, factores que deben ser tomados en cuenta para una adecuada planificación rural de la península


Abstract The present work describes a geomorpholopic evaluation of the Burica peninsula, during 9 days in January 2008. Coastal geomorphology, erosion and depositional zones were evaluated between punta Banco and punta El Mangle. The most important morphologies found were structural origin morphologies, represented by active tectonic deformation, produced by the Panamá Fracture Zone, and the subduction of the Cocos ridge. The structural origin morphologies identified were, structural-denudational zones which dominate the study area, homocline in the south of the peninsula and structural terraces, that are observed easily between punta El Mangle and La Peña, and in punta Banco. Other morphologies were identified, such as marine, fluvial and denudational morphologies. The marine-origin morphologies include the beach, subdivided in subareas, separated due to the waves dynamic, the cliffs, that dominate the area between La Peña river and punta Banco, and the shore platforms in the area between punta El Mangle and La Peña. The denudational morphology is represented by landslides, which area present mainly in the cliffs. In the other hand, the fluvial origin morphologies, include La Peña, Peñita, Caña Blanca and Coco mouths and the floodplain of La Peña river. Intense erosional, slight to moderate erosional, sedimentational, and erosion and sedimentational zones were identified, having a great importance the coastal erosion, especially observed in the central and south of the peninsula. Considering the results and the interaction of them, the main hazards found are landslides, coastal erosion and the high seismicity of the area, which should be taken into account and studied in detail for a proper planning of the rural development.
