Construindo aprendizagens em ambiente inclusivo

Este projecto teve como objectivo a intervenção num grupo de alunos de 3º ano de escolaridade inserido numa escola pertencente ao Agrupamento de Escolas vermelho. Neste grupo de alunos está inserida uma aluna com dislexia do tipo auditivo e com deficit de atenção. A mesma está integrada no Regime Educativo Especial, Decreto – lei 3/2008 de 7 de Janeiro, nas alíneas a) Apoio Pedagógico Personalizado, b) Adequações Curriculares Individuais e d) Adequações no Processo de Avaliação. Foram utilizadas técnicas e instrumentos de pesquisa de dados, tais como, entrevista, pesquisa documental, sociometria e observação. Após a análise dos dados recolhidos com base nas técnicas e instrumentos utilizados na recolha dos dados, fez-se a caracterização do grupo ao nível das aprendizagens e da socialização. A intervenção foi desenvolvida através de metodologias de aprendizagem cooperativa e ensino diferenciado. Com a aplicação destas metodologias pretendeu-se responder às necessidades de todos os alunos do grupo numa perspectiva inclusiva.

A Melancolia de Albercht Dürer (1471-1528)

Acreditamos que só a partir de um determinado número de provas e de clara mestria, se podia considerar a passagem de iniciado a Mestre. Julgamos que foi o que aconteceu a Dürer quando chegou pela primeira vez a Veneza. É provável que nesta cidade existisse uma representação da Nova Academia ou confraria congénere, e que nela tenha sido aceite, mas só durante a sua segunda visita entre 1505-1507, é que lhe foi reconhecido o grau de Mestre.

El bloque de constitucionalidad pergeñado por el Tribunal Constitucional (Artículos Varios)

Las siguientes líneas glosan una importante Resolución del Tribunal Constitucional ecuatoriano, que por primera vez esboza el difícil concepto de bloque de constitucionalidad. Para hacerlo, el autor comienza narrando de forma sucinta los antecedentes del fallo, luego especifica cuáles fueron las principales consideraciones del Tribunal y finaliza esta primera parte del artículo pergeñando, a la luz de la Resolución, la noción ecuatoriana de bloque de constitucionalidad. Mas, lo verdaderamente interesante de este trabajo viene cuando se señalan algunas trascendentales implicaciones prácticas de la adopción de éste nuevo concepto. Por ejemplo: redimensiona la hermenéutica jurídica, eleva los tratados de derechos humanos y algunas otras normas -incluso internas- al estatus constitucional, entre otros interesantísimos efectos.

Can the dynamical impact of the stratosphere on the troposphere be described by large-scale adjustment to the stratospheric PV distribution?

Recent numerical experiments have demonstrated that the state of the stratosphere has a dynamical impact on the state of the troposphere. To account for such an effect, a number of mechanisms have been proposed in the literature, all of which amount to a large-scale adjustment of the troposphere to potential vorticity (PV) anomalies in the stratosphere. This paper analyses whether a simple PV adjustment suffices to explain the actual dynamical response of the troposphere to the state of the stratosphere, the actual response being determined by ensembles of numerical experiments run with an atmospheric general-circulation model. For this purpose, a new PV inverter is developed. It is shown that the simple PV adjustment hypothesis is inadequate. PV anomalies in the stratosphere induce, by inversion, flow anomalies in the troposphere that do not coincide spatially with the tropospheric changes determined by the numerical experiments. Moreover, the tropospheric anomalies induced by PV inversion are on a larger scale than the changes found in the numerical experiments, which are linked to the Atlantic and Pacific storm-tracks. These findings imply that the impact of the stratospheric state on the troposphere is manifested through the impact on individual synoptic-scale systems and their self-organization in the storm-tracks. Changes in these weather systems in the troposphere are not merely synoptic-scale noise on a larger scale tropospheric response, but an integral part of the mechanism by which the state of the stratosphere impacts that of the troposphere.

Unification of the probe and singular sources methods for the inverse boundary value problem by the no-response test

In this article, we use the no-response test idea, introduced in Luke and Potthast (2003) and Potthast (Preprint) and the inverse obstacle problem, to identify the interface of the discontinuity of the coefficient gamma of the equation del (.) gamma(x)del + c(x) with piecewise regular gamma and bounded function c(x). We use infinitely many Cauchy data as measurement and give a reconstructive method to localize the interface. We will base this multiwave version of the no-response test on two different proofs. The first one contains a pointwise estimate as used by the singular sources method. The second one is built on an energy (or an integral) estimate which is the basis of the probe method. As a conclusion of this, the probe and the singular sources methods are equivalent regarding their convergence and the no-response test can be seen as a unified framework for these methods. As a further contribution, we provide a formula to reconstruct the values of the jump of gamma(x), x is an element of partial derivative D at the boundary. A second consequence of this formula is that the blow-up rate of the indicator functions of the probe and singular sources methods at the interface is given by the order of the singularity of the fundamental solution.

Floral morphology and development in quillajaceae and surianaceae (Fabales), the species-poor relatives of leguminosae and polygalaceae

Background and Aims: Molecular phylogenies have suggested a new circumscription for Fabales to include Leguminosae, Quillajaceae, Surianaceae and Polygalaceae. However, recent attempts to reconstruct the interfamilial relationships of the order have resulted in several alternative hypotheses, including a sister relationship between Quillajaceae and Surianaceae, the two species-poor families of Fabales. Here, floral morphology and ontogeny of these two families are investigated to explore evidence of a potential relationship between them. Floral traits are discussed with respect to early radiation in the order. Methods: Floral buds of representatives of Quillajaceae and Surianaceae were dissected and observed using light microscopy and scanning electron microscopy. Key Results Quillajaceae and Surianaceae possess some common traits, such as inflorescence morphology and perianth initiation, but development and organization of their reproductive whorls differ. In Quillaja, initiation of the diplostemonous androecium is unidirectional, overlapping with the petal primordia. In contrast, Suriana is obdiplostemonous, and floral organ initiation is simultaneous. Independent initiation of five carpels is common to both Quillaja and Suriana, but subsequent development differs; the antesepalous carpels of Quillaja become fused proximally and exhibit two rows of ovules, and in Suriana the gynoecium is apocarpous, gynobasic, with antepetalous biovulate carpels. Conclusions: Differences in the reproductive development and organization of Quillajaceae and Surianaceae cast doubt on their potential sister relationship. Instead, Quillaja resembles Leguminosae in some floral traits, a hypothesis not suggested by molecular-based phylogenies. Despite implicit associations of zygomorphy with species-rich clades and actinomorphy with species-poor families in Fabales, this correlation sometimes fails due to high variation in floral symmetry. Studies considering specific derived clades and reproductive biology could address more precise hypotheses of key innovation and differential diversification in the order.

Effect of H-bonding on the ambivalence of SCN- towards copper(II)

Condensations of 2-(2-aminoethyl)pyridine with 4-methylimidazole-5-carboxaldehyde and 1-methyl-2-imidazolecarboxaldehyde generate the tridentate N donor ligands L and L' respectively. Reactions of Cu(NCS)(2) with L and L' yield respectively CuL(SCN)(NCS) (1) containing a CuN4S core and CuL'(NCS)(2) (2) having a CuN5 core. Both the cores are square pyramidal with SCN bound in 1 at the axial position through the S end. This differential behaviour of SCN in the two complexes despite the ligands being very similar, is investigated by DFT calculations at the B3LYP/TZV level. It is found that DFT calculations predict isolation of the Cu(ligand)(NCS)(2) species for both the ligands L and L'. Presence of an offsetting intermolecular H-bonding between the N atom of the thiocyanate and the N-H proton of the ligand L of an adjacent molecule makes the binding of SCN via the S end feasible in 1 resulting in the H-bonded-dimer Cu2L2(SCN)(2)(NCS)(2). The strength of the H-bond is estimated as 27.1 kJ mol (1) from the DFT calculations. The question of such H-bonding does not arise with L' as it lacks in a similar H atom.
