A avaliação do desempenho dos professores e supervisão pedagógica : um percurso de e para a qualidade educativa

Description: [por] Com a implementação do Modelo de Avaliação do Desempenho Docente (MADD), pelo Decreto-lei nº 15/2007 de 19 de Janeiro, a educação em geral, e em particular os professores portugueses, têm de diferentes formas manifestado o seu descontentamento quanto às medidas subjacentes ao modelo aprovado. ...

Parásitos del caracol "Helix aspersa" Müller, 1774 en explotaciones helicicultoras de Galicia

Description: La helicicultura es una excelente alternativa para obtener caracoles comestibles pero su viabilidad se ve seriamente amenazada por patógenos. En la presente Tesis Doctoral se llevó a cabo un estudio parasitológico en 3 granjas de Galicia (noroeste España) con sistema de cría mixto detectándose las e...

Three-dimensional Fourier transform evaluation of sequences of spatially and temporally modulated speckle interferograms

Description: Phase evaluation methods based on the 2D spatial Fourier transform of a speckle interferogram with spatial carrier usually assume that the Fourier spectrum of the interferogram has a trimodal distribution, i. e. that the side lobes corresponding to the interferential terms do not overlap the other t...

Animación abstracta : técnica y estética de una corriente cinematográfica ligada al arte conceptual y de vanguardia del siglo XX

Description: La tesis pretende situar la animación abstracta en su contexto histórico y conceptual, además de recuperar para la historia de la animación a un grupo de directores, generalmente encuadrados en el término genérico de "experimentales", pero con una obra dentro de la abstracción cinematográfica con té...

Testing for one-sided alternatives in nonparametric censored regression

Description: Assume that we have two populations (X 1,Y 1) and (X 2,Y 2) satisfying two general nonparametric regression models Y j =m j (X j )+ε j , j=1,2, where m(⋅) is a smooth location function, ε j has zero location and the response Y j is possibly right-censored. In this paper, we propose to test the null ...

DTDA : an R package to analyze randomly truncated data

Description: In this paper, the R package DTDA for analyzing truncated data is described. This package contains tools for performing three different but related algorithms to compute the nonparametric maximum likelihood estimator of the survival function in the presence of random truncation. More precisely, the ...

‘SGoFicance Trace’ : assessing significance in high dimensional testing problems

Description: Recently, an exact binomial test called SGoF (Sequential Goodness-of-Fit) has been introduced as a new method for handling high dimensional testing problems. SGoF looks for statistical significance when comparing the amount of null hypotheses individually rejected at level γ = 0.05 with the expected...

Tests for the equality of conditional variance functions in nonparametric regression

Description: In this paper we are interested in checking whether the conditional variances are equal in k ≥ 2 location-scale regression models. Our procedure is fully nonparametric and is based on the comparison of the error distributions under the null hypothesis of equality of variances and without making use ...

A review on ROC curves in the presence of covariates

Description: In this paper we review the literature on ROC curves in the presence of covariates. We discuss the different approaches that have been proposed in the literature to define, model, estimate and do asymptotics for ROC curves that incorporate covariates. For reasons of brevity, we mostly focus on nonpa...

Phase-shifted double single-pulse additive stroboscopic TV holography for the measurement of high-frequency vibrations using low-bandwidth phase-modulation devices

Description: We present a novel technique for the application of stroboscopic additive TV-holography to the measurement of vibrations using temporal phase-shifting. Based on a previous concept - contrived and developed by the same authors - that used two illumination pulses within each vibration cycle and interp...
