Liderança singular na escola plural : as culturas da escola perante o processo de avaliação externa

Numa altura em que a instituição escola alcança níveis de sofisticação cultural e organizacional inéditos, assistimos à implementação de uma liderança unipessoal, centrada na figura do Diretor de escola/agrupamento. Contudo, este novo rosto, erguido paradigma da nova gestão escolar, defronta-se com as múltiplas caras das escolas públicas, cada vez mais mascaradas face à imposição de um modelo de liderança unidimensional. Partindo deste cenário, focamos a nossa abordagem sobre: i) os traços que têm vindo a institucionalizar um perfil-ideal de liderança escolar; ii) até que ponto a liderança unipessoal servirá (melhor)como veículo de expressão de uma cultura escolar que se pretende reproduzir nas diversas escolas; iii) de que modo o rosto (Diretor) exercerá um efeito homogeneizador, marcando quadros de interação e lógicas de organização, sobre o quodiano das escolas. As questões enunciadas serão exploradas utilizando como dispositivo metodológico a análise crítica dos Relatórios de Avaliação Externa das Escolas produzidos durante o I ciclo avaliativo (2006-2011), com o objetivo de apreender os modelos implícitos de cultura de escola e de liderança e as suas implicações na reconfiguração do quotidiano das escolas.

Understanding African easterly waves: a moist singular vector approach

Moist singular vectors (MSV) have been applied successfully to predicting mid-latitude storms growing in association with latent heat of condensation. Tropical cyclone sensitivity has also been assessed. Extending this approach to more general tropical weather systems here, MSVs are evaluated for understanding and predicting African easterly waves, given the importance of moist processes in their development. First results, without initial moisture perturbations, suggest MSVs may be used advantageously. Perturbations bear similar structural and energy profiles to previous idealised non-linear studies and observations. Strong sensitivities prevail in the metrics and trajectories chosen, and benefits of initial moisture perturbations should be appraised. Copyright © 2009 Royal Meteorological Society

A singular vector perspective of 4DVAR: The spatial structure and evolution of baroclinic weather systems

The extent to which the four-dimensional variational data assimilation (4DVAR) is able to use information about the time evolution of the atmosphere to infer the vertical spatial structure of baroclinic weather systems is investigated. The singular value decomposition (SVD) of the 4DVAR observability matrix is introduced as a novel technique to examine the spatial structure of analysis increments. Specific results are illustrated using 4DVAR analyses and SVD within an idealized 2D Eady model setting. Three different aspects are investigated. The first aspect considers correcting errors that result in normal-mode growth or decay. The results show that 4DVAR performs well at correcting growing errors but not decaying errors. Although it is possible for 4DVAR to correct decaying errors, the assimilation of observations can be detrimental to a forecast because 4DVAR is likely to add growing errors instead of correcting decaying errors. The second aspect shows that the singular values of the observability matrix are a useful tool to identify the optimal spatial and temporal locations for the observations. The results show that the ability to extract the time-evolution information can be maximized by placing the observations far apart in time. The third aspect considers correcting errors that result in nonmodal rapid growth. 4DVAR is able to use the model dynamics to infer some of the vertical structure. However, the specification of the case-dependent background error variances plays a crucial role.

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.
