O presente trabalho tem como objetivo caracterizar o risco nas comunidades Mazagão 1 e José da Silva Sobral, a partir de indicadores sociais de vulnerabilidade e ambientais de perigo para movimentos de massa. Para isso, buscou-se inicialmente o levantamento bibliográfico, respaldando-se em autores que trabalham com as temáticas de riscos e vulnerabilidade, e foram realizadas atividades de campo, as quais possibilitaram a aplicação dos questionários de vulnerabilidade social e das fichas de exposição a movimentos de massa, além de permitir a realização de registros fotográficos. A partir da sistematização dos dados de vulnerabilidade social e de exposição, permitiu-se estabelecer as características mais presentes nas comunidades, indicando os elementos mais críticos, os quais colaboram para que haja risco de movimentos de massa, apontando então para a necessidade de pesquisas que venham a estudar profundamente a situação, podendo vir a propor medidas mitigadoras diretamente aplicáveis à área de risco.Palavras-chave: Vulnerabilidade; Perigo; Desastre. ABSTRACTThe present work aims to characterize the risk in the communities Mazagão 1 and José da Silva Sobral, considering social indicators of vulnerability and environmental indicators of danger to mass movements. In order to do this, a bibliographical survey was sought, supported by authors working on the themes of risk and vulnerability, and field activities were carried out, which made possible the application of the social vulnerability questionnaires and the exposure sheets to mass movements, besides allowing the realization of photographic records. Systematizing social vulnerability and exposure data, the most present characteristics in the communities were established, indicating the most critical elements, which contribute to the risk of mass movements, pointing to the need for research that will deeply study the situation, and may propose mitigating measures directly applicable to the area of risk.Keywords: Vulnerability; Danger; Disaster. RESUMENEste trabajo tiene como objetivo caracterizar el riesgo en las comunidades Mazagão 1 y José da Silva Sobral, con base en indicadores sociales de vulnerabilidad y peligro ambiental para los movimientos de masas.

This chapter aims to convince Homerists and their fellow travelers in classical studies that they will find this entire book of value and to persuade those with interests in comparative literature, ethnography, folkloristics, and linguistic anthropology that they should at least read Part I. The chapter reviews the precedents for and goals of this study, defends the choice of the phrases “the Iliad poet” and “the Odyssey poet,” explains the comparative methods used, provides a bibliographical survey of the modern oral poetries investigated in the book, defines a simile, and summarizes the contents of each chapter.

AbstractIn the field of Model-Driven Engineering, Triple Graph Grammars (TGGs) play an important role as a rule-based means of implementing consistency management. From a declarative specification of a consistency relation, several operations including forward and backward transformations, (concurrent) synchronisation, and consistency checks can be automatically derived. For TGGs to be applicable in realistic application scenarios, expressiveness in terms of supported language features is very important. A TGG tool is schema compliant if it can take domain constraints, such as multiplicity constraints in a meta-model, into account when performing consistency management tasks. To guarantee schema compliance, most TGG tools allow application conditions to be attached as necessary to relevant rules. This strategy is problematic for at least two reasons: First, ensuring compliance to a sufficiently expressive schema for all previously mentioned derived operations is still an open challenge; to the best of our knowledge, all existing TGG tools only support a very restricted subset of application conditions. Second, it is conceptually demanding for the user to indirectly specify domain constraints as application conditions, especially because this has to be completely revisited every time the TGG or domain constraint is changed. While domain constraints can in theory be automatically transformed to obtain the required set of application conditions, this has only been successfully transferred to TGGs for a very limited subset of domain constraints. To address these limitations, this paper proposes a search-based strategy for achieving schema compliance. We show that all correctness and completeness properties, previously proven in a setting without domain constraints, still hold when schema compliance is to be additionally guaranteed. An implementation and experimental evaluation are provided to support our claim of practical applicability.
