PRISMA: towards quality, aspect oriented and dynamic software architectures

The development of software systems must be done using platforms that allow the description of quality, complex, distributed, dynamic and reusable architectural models. We present in this paper PRISMA, an architectural modelling approach based on aspects and components that uses a component definition language (components, connectors and systems) to define architectural types at a high abstraction level and a configuration language to design the architecture of software systems. The component definition language increases reuse allowing importation of COTS and reduces complexity by integrating two modern software development approaches: component-based software development and aspect-orient…

Diferencias en habilidades y conducta entre grupos de preescolares de alto y bajo rendimiento escolar

Resumen basado en el del autor Título, resumen y palabras clave en español e inglés Disponible la versión en inglés Se analiza la relación entre variables psicológicas y rendimiento escolar en niños preescolares. Se ha seleccionado un conjunto de variables cognitivas y conductuales, que según la bibliografía más actualizada se relacionan con el aprendizaje escolar, con el fin de identificar los factores que parecen influir en el rendimiento educativo en la etapa infantil. La meta final es intentar prevenir problemas de rendimiento futuros mediante la identificación temprana de estas variables en los niños que parecen presentar bajo rendimiento. La muestra se compone de 47 niños: 23 con alto…

A Web-Based Coordination Infrastructure for Grid Collective Services

Virtual Organizations (VO) consisting of heterogeneous institutions and individuals that share resources dynamically and in a coordinated way to support collaborative problem-solving are emerging in many fields. Consequently, new types of distributed infrastructures known as Grids have been proposed to cope with these new sharing requirements. Grids offer sets of collective services to support collaborative tasks which are distributed in nature and need asynchronous communication. Existing approaches to this problem lack of flexibility, adaptability and are tightly bound to the collective service that is provided. We present here a generic event model to build collective services that requi…
