The Differentiation and Promotion of Studentsâ Rights in Portugal
This investigation includes a differential study (Study 1)
and a quasi-experimental research (Study 2). In Study 1, the objective
was to establish to what extent studentsâ rights existed and analyse
the differentiation between studentsâ rights with Portuguese and
immigrant mothers, throughout school years. The sample consisted of
537 students with Portuguese and immigrant mothers, distributed by
different school years (7th, 9th and 11th grades). The Childrenâs Rights
Scale (Hart et al., 1996; Veiga, 2001) was used. In Study 2, the purpose
was to analyse the effects on studentsâ rights of the use by teachers of a
communicational intervention program, supervised by school psychologists.
The sample involved 7th and 9th grade students, in a total of
four classes, two forming the experimental groups (n = 36) and two the
control groups (n = 43); as in Study 1, the Childrenâs Rights Scale was used. The results indicated the effectiveness of the communicational intervention program on studentsâ rights and are consistent with previous studies. An implication is that psychologists and teachers, working together and taking a human rights perspective, may develop an important role in projects to promote the studentsâ rights

Unraveling 5f-6d hybridization in uranium compounds via spin-resolved L-edge spectroscopy
FUNDAĂĂO DE AMPARO Ă PESQUISA DO ESTADO DE SĂO PAULO - FAPESPCOORDENAĂĂO DE APERFEIĂOAMENTO DE PESSOAL DE NĂVEL SUPERIOR - CAPESThe multifaceted character of 5f electrons in actinide materials, from localized to itinerant and in between, together with their complex interactions with 6d and other conduction electron states, has thwarted efforts for fully understanding this class of compounds. While theoretical efforts abound, direct experimental probes of relevant electronic states and their hybridization are limited. Here we exploit the presence of sizable quadrupolar and dipolar contributions in the uranium L-3-edge X-ray absorption cross section to provide unique information on the extent of spin-polarized hybridization between 5f and 6d electronic states by means of X-ray magnetic circular dichroism. As a result, we show how this 5f-6d hybridization regulates the magnetism of each sublattice in UCu2Si2 and UMn2Si2 compounds, demonstrating the potentiality of this methodology to investigate a plethora of magnetic actinide compounds.816FUNDAĂĂO DE AMPARO Ă PESQUISA DO ESTADO DE SĂO PAULO - FAPESPCOORDENAĂĂO DE APERFEIĂOAMENTO DE PESSOAL DE NĂVEL SUPERIOR - CAPESFUNDAĂĂO DE AMPARO Ă PESQUISA DO ESTADO DE SĂO PAULO - FAPESPCOORDENAĂĂO DE APERFEIĂOAMENTO DE PESSOAL DE NĂVEL SUPERIOR - CAPES10/19979-92013/22436-52014/05480-32014/26620-8Sem informaçãoWe are thankful to Roberto Caciuffo and Gerry Lander for discussions and comments on the manuscript.
