Ontology-based patterns for the integration of business processes and enterprise application architectures

Increasingly, enterprises are using Service-Oriented Architecture (SOA) as an approach to Enterprise Application Integration (EAI). SOA has the potential to bridge the gap between business and technology and to improve the reuse of existing applications and the interoperability with new ones. In addition to service architecture descriptions, architecture abstractions like patterns and styles capture design knowledge and allow the reuse of successfully applied designs, thus improving the quality of software. Knowledge gained from integration projects can be captured to build a repository of semantically enriched, experience-based solutions. Business patterns identify the interaction and structure between users, business processes, and data. Specific integration and composition patterns at a more technical level address enterprise application integration and capture reliable architecture solutions. We use an ontology-based approach to capture architecture and process patterns. Ontology techniques for pattern definition, extension and composition are developed and their applicability in business process-driven application integration is demonstrated

Service architecture design for E-Businesses: A pattern-based approach

E-business involves the implementation of business processes over the Web. At a technical level, this imposes an application integration problem. In a wider sense, the integration of software and business levels across organisations becomes a significant challenge. Service architectures are an increasingly adopted architectural approach for solving Enterprise Applications Integration (EAI). The adoption of this new architectural paradigm requires adaptation or creation of novel methodologies and techniques to solve the integration problem. In this paper we present the pattern-based techniques supporting a methodological framework to design service architectures for EAI. The techniques are used for services identification, for transformation from business models to service architectures and for architecture modifications

Institutions, Social Networks, and Conflicts in Guinea-Bissau: Results from a 2005 Survey

Guinea-Bissau endured a major conflict in 1998 and has suffered from persistent political instability since independence. After a brief review of indicators of governance in Guinea-Bissau and recent political developments, the objective of this Chapter is to provide results from a recent survey that gives insights into the opinions of the population, among others, about changes in well-being over time, trust in various institutions, sources of conflicts at the local level, and ways to deal with conflicts. There is a clear perception among citizens that there has been a decline in well-being as a result of the conflict, as well as a lack of improvement since then, at least for those in poverty who are highly vulnerable. The data suggest an increase in the lack of security after the conflict and no clear sign of improvement. The population has little trust in national institutions such as the army, the police, the judicial system, and the central government. Local conflicts often emerge because of the competition for scarce productive resources, but poorer households deal with these conflicts differently than wealthier households.Conflict; Institutions; Social Capital; Poverty; Guinea-Bissau

Conflict, Livelihoods, and Poverty in Guinea-Bissau: An Overview

Conflict and political instability have considerably weakened Guinea-Bissau’s productive infrastructure during the past three decades. This situation has contributed to an increase in the degree of vulnerability of the population, especially in rural areas. As growth has been weak, poverty levels have remained high. This paper serves as an introduction and overview for a book that provides a collection of papers on conflict, livelihoods, and poverty in Guinea-Bissau based on both a nationally representative 2002 household survey and a small-scale survey with both quantitative and qualitative components implemented in 2004. After a brief review of political developments since independence, this overview summarizes the report’s main findings in the areas of conflict, growth and poverty, institutions and social networks, the characteristics of the poor and determinants of poverty, the population’s means of livelihood, and, finally, cashew production and taxation.Conflict; Livelihoods; Poverty; Gionea-Bissau

Ontology-based composition and matching for dynamic cloud service coordination

Recent cross-organisational software service offerings, such as cloud computing, create higher integration needs. In particular, services are combined through brokers and mediators, solutions to allow individual services to collaborate and their interaction to be coordinated are required. The need to address dynamic management - caused by cloud and on-demand environments - can be addressed through service coordination based on ontology-based composition and matching techniques. Our solution to composition and matching utilises a service coordination space that acts as a passive infrastructure for collaboration where users submit requests that are then selected and taken on by providers. We discuss the information models and the coordination principles of such a collaboration environment in terms of an ontology and its underlying description logics. We provide ontology-based solutions for structural composition of descriptions and matching between requested and provided services

Fragmentación y marginalidad del sujeto femenino en cinco obras de Juan Radrigán

El teatro de Juan Radrigán se presenta como una evidencia de la realidad chilena durante los años de la dictadura militar vivida en Chile bajo el control del General Augusto Pinochet. Dentro de las obras teatrales de Radrigán se aprecia la construcción de sujetos femeninos que escapan de la imagen típica del "ángel del hogar", mostrándose como seres complejos con identidades propias que se ven afectados por las situación que se vivió Chile durante el periodo de la dictadura militar

Graph-based Pattern Matching and Discovery for Process-centric Service Architecture Design and Integration

Process automation and applications integration initiatives are often complex and involve significant resources in large organisations. The increasing adoption of service-based architectures to solve integration problems and the widely accepted practice of utilising patterns as a medium to reuse design knowledge motivated the definition of this work. In this work a pattern-based framework and techniques providing automation and structure to address the process and application integration problem are proposed. The framework is a layered architecture providing modelling and traceability support to different abstraction layers of the integration problem. To define new services - building blocks of the integration solution - the framework includes techniques to identify process patterns in concrete process models. Graphs and graph morphisms provide a formal basis to represent patterns and their relation to models. A family of graph-based algorithms support automation during matching and discovery of patterns in layered process service models. The framework and techniques are demonstrated in a case study. The algorithms implementing the pattern matching and discovery techniques are investigated through a set of experiments from an empirical evaluation. Observations from conducted interviews to practitioners provide suggestions to enhance the proposed techniques and direct future work regarding analysis tasks in process integration initiatives

Concilio Vaticano II.

La siguiente reflexión se enmarca en la celebración de los cincuenta años del Concilio Vaticano II realizada en la UCN, convocada por CONFERRE Antofagasta. Para ello nos hemos servido de la Constitución Gaudium et spes, fjando nuestro interés en la dimensión unitaria del hombre a partir de la expresión de su corporeidad
