Due to the complex infrastructure of web applications (using application servers, web servers, database servers, etc.) response times perceived by clients can be significantly larger than they would like. The same can be applied to web services that have been implemented using the same web technology. On the other side, repeated invocations to the same "readonly" web service with the same request data may often produce the same response from the provider, what can be considered a useless work. In the search for a performance improvement, we propose a cachebased extension to the architecture that can enhance current web services architecture.

Nowadays, organisations increasingly need to adapt to the fast evolution of markets and societies in our globalised world in order to be competitive. Therefore, it is essential to take the right decisions when it comes to invest in research and development (R&D) projects. However, an issue that has not been given much attention is how to measure the social impact (or return) of R&D projects. In this exploratory study, the findings of an analysis of how R&D projects are assessed and selected, including this social perspective, are presented. The methodology which has been used in this research includes both interviews and analysis of the data obtained through them. The major finding is that in the current situation the social impact is not taken into account, but is growing the awareness of this perspective among different types of organizations dealing with R&D activities.

El objeto del trabajo ahora presentado se centra en la protección de los datos personales en un mundo globalizado dónde el auge de la tecnología está al orden del día y que donde los datos personales constituyen un elemento más a tener en cuenta a la hora de determinar la participación de un determinado sujeto en un hecho criminal. Ahora bien, debemos partir de la naturaleza sensible de estos datos recopilados y la incidencia de los mismos en nuestros derechos fundamentales. En este trabajo, nos vamos a referir especialmente al derecho a la protección de datos de carácter personal y la utilización de estos en el ámbito criminal.
