Whitepaper: A QTI Management System for Service Oriented Architectures

by Universitat Pompeu FabraJan 01, 2008

The IMS Question & Test Interoperability (QTI) specification describes a data model for the representation of questions and tests data and their corresponding results reports. This research paper from Universitat Pompeu Fabra discusses a more elaborated implementation of a module-structured online engine for the (QTI) specification, aiming at providing a framework for the development of user friendly IMS-QTI applications. This work is considered as a continuation of the APIS project that intends to develop an infrastructure that sustains interoperability and web servicing of IMS-QTI.


Whitepaper: Optimal Design Of Social Security Reforms

by Universitat Pompeu FabraJan 01, 2008

This research paper studies the optimal design of a social security privatization in a Pareto improving way. The government decides endogenously how to finance the transition and the welfare of the initial generations alive becomes policy constraint. Researchers find that the government can design a Pareto improving reform that exhibits sizeable welfare gains, arising because of a reduction in labor supply distortions. In contrast, the welfare gain from reducing savings distortions is relatively small. Their approach explicitly provides quantitative policy prescriptions towards the policy design of future and maybe unavoidable social security reforms.


Whitepaper: An Easy Way to Develop Mobile and Wireless Applications

by Universitat Pompeu FabraJan 01, 2008

An API that offers many advantages is Parlay and Open Service Access (OSA). Although this API facilitates the services development, it is still very complex, difficult and hard to use. To try to solve this situation, many operators and service providers offer their different development tools, SDKs (Software Development Kit), that facilitate the development and implementation phases. These tools simplify the use of the API. This research paper begins with an introduction about the Parlay/OSA (P/OSA) API. It shows a general idea about the API and its complexity.
