Com o estudo que agora se apresenta pretende-se realizar o mapeamento da oferta nacional de formação no âmbito da administração educacional, nos ciclos de estudo que habilitam profissionalmente para a docência na educação pré-escolar, no 1.º e no 2.º ciclo do ensino básico, procurando definir e categorizar as tendências gerais das abordagens e as conceções de administração educacional presentes nas unidades curriculares, tendo em conta as orientações epistemológicas que lhes estão subjacentes. Decorrente do referido estudo, a presente comunicação focaliza-se na reflexão sobre o lugar e a pertinência da formação em Administração Educacional (AE) no âmbito da especificidade dos cursos de mestrado profissionalizantes (em educação pré-escolar e em ensino do 1.º e do 2.º ciclo do ensino básico) ministrados numa escola superior de educação, tendo como referência as lógicas de organização e de desenvolvimento dessa formação e as representações dos estudantes a quem se destina.

This paper addresses the estimation of object boundaries from a set of 3D points. An extension of the constrained clustering algorithm developed by Abrantes and Marques in the context of edge linking is presented. The object surface is approximated using rectangular meshes and simplex nets. Centroid-based forces are used for attracting the model nodes towards the data, using competitive learning methods. It is shown that competitive learning improves the model performance in the presence of concavities and allows to discriminate close surfaces. The proposed model is evaluated using synthetic data and medical images (MRI and ultrasound images).

In this work, we present results from teleseismic P-wave receiver functions (PRFs) obtained in Portugal, Western Iberia. A dense seismic station deployment conducted between 2010 and 2012, in the scope of the WILAS project and covering the entire country, allowed the most spatially extensive probing on the bulk crustal seismic properties of Portugal up to date. The application of the H-kappa stacking algorithm to the PRFs enabled us to estimate the crustal thickness (H) and the average crustal ratio of the P- and S-waves velocities V (p)/V (s) (kappa) for the region. Observations of Moho conversions indicate that this interface is relatively smooth with the crustal thickness ranging between 24 and 34 km, with an average of 30 km. The highest V (p)/V (s) values are found on the Mesozoic-Cenozoic crust beneath the western and southern coastal domain of Portugal, whereas the lowest values correspond to Palaeozoic crust underlying the remaining part of the subject area. An average V (p)/V (s) is found to be 1.72, ranging 1.63-1.86 across the study area, indicating a predominantly felsic composition. Overall, we systematically observe a decrease of V (p)/V (s) with increasing crustal thickness. Taken as a whole, our results indicate a clear distinction between the geological zones of the Variscan Iberian Massif in Portugal, the overall shape of the anomalies conditioned by the shape of the Ibero-Armorican Arc, and associated Late Paleozoic suture zones, and the Meso-Cenozoic basin associated with Atlantic rifting stages. Thickened crust (30-34 km) across the studied region may be inherited from continental collision during the Paleozoic Variscan orogeny. An anomalous crustal thinning to around 28 km is observed beneath the central part of the Central Iberian Zone and the eastern part of South Portuguese Zone.
