Relativistic quantum motion of spin-0 particles under the influence of non-inertial effects in the cosmic string space-time
We study solutions for the Klein-Gordon equation with vector and scalar
potentials of the Coulomb types under the influence of non-inertial effects in
the space-time of topological defects. We also investigate a quantum particle
described by the Klein-Gordon oscillator in the background space-time generated
by a string. An important result obtained is that the non-inertial effects
restrict the physical region of the space-time where the particle can be
placed. In addition, we show that these potentials can form bound states for
the relativistic wave equation equation in this kind of background.Comment: arXiv admin note: text overlap with arXiv:1608.0669
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
