On the weak field approximation of Brans-Dicke theory of gravity
It is shown that in the weak field approximation solutions of Brans-Dicke
equations are simply related to the solutions of General Relativity equations
for the same matter distribution. A simple method is developed which permits to
obtain Brans-Dicke solutions from Einstein solutions when both theories are
considered in their linearized forms. To illustrate the method some examples
found in the literature are discussed.Comment: 12 pages, latex, no figure
State Responsibility for Fostering Participation and Social Justice. Some Reflections on Policies for Low Skilled Adults in Portugal and Italy
This article aims at discussing the state responsibility concerning educational rights as a framework to problematize issues of social justice on two national contexts of South Europe with an expressive vulnerable adult population concerning qualifications. We supported our analysis of national ALE public policies on Toma\u161evski (2001) theoretical and analytical framework that focuses on the accomplishment of the right of education by national states. Research goals are to analyse and compare ALE as a human right in the context of both states obligations, and to qualitatively evaluate selected national policies as fostering participation and social justice. This article responds to the follow question: what are the national policies that contribute to express ALE as a human right and why? It presents the scenarios obtained through Toma\u161evski model and point out to interesting differences between Portuguese and Italian case
