Tese de mestrado, Ciências da Educação (Formação de Professores), Universidade de Lisboa, Instituto de Educação, 2013 ; A presente dissertação aborda o domínio da formação contínua de professores, mais especificamente o da avaliação das ações de formação, focando-se o nosso estudo nos efeitos percebidos pelos formandos. Para o estudo selecionámos uma das ações de formação inseridas no Programa de Formação Cont...

Designing screws for polymer compounding in twin-screw extruders

Tese de doutoramento em Ciência e Engenharia de Polímeros e Compósitos ; Considering its modular construction, co-rotating twin screw extruders can be easily adapted to work with polymeric systems with more stringent specifications. However, their geometrical flexibility makes the performance of these machines strongly dependent on the screw configuration. Therefore, the definition of the adequate screw geomet...

The brazilian preference: cesarean delivery among immigrants in Portugal

To evaluate how the country of origin affects the probability of being delivered by cesarean section when giving birth at public Portuguese hospitals. STUDY DESIGN: Women delivered of a singleton birth (n = 8228), recruited from five public level III maternities (April 2005-August 2006) during the procedure of assembling a birth cohort, were classified according to the country of origin and her migration status...

Risk of caesarean section after induced labour: do hospitals make a difference?

Background: There is a well-known relationship between induced labour and caesarean rates. However, it remains unknown whether this relationship reflects the impact of more complex obstetric conditions or the variability in obstetric practices. We sought to quantify the independent role of the hospital as a variable that can influence the occurrence of caesarean section after induced labour. As part of the Port...

Estimating child mortality from information on previous birth: data from a Port...

A whole range of techniques have been developed for estimating infant and child mortality from the information routinely recorded in maternity registers on age and reproductive history of delivering mothers. Among them, the best-known and most widely applied indirect technique was developed by William Brass. Using the baseline information from a birth cohort (Generation XXI) assembled in the period 2005-2006 in...

Multi-objective ant colony optimization for the twin-screw configuration problem

The Twin-Screw Configuration Problem (TSCP) consists in identifying the best location of a set of available screw elements along a screw shaft. Due to its combinatorial nature, it can be seen as a sequencing problem. In addition, different conflicting objectives may have to be considered when defining a screw configuration and, thus, it is usually tackled as a multi-objective optimization problem. In this resea...

Timing of birth and mode of delivery after spontaneous labour onset

Background High caesarean rates are a matter of concern and the influence of hospital functioning in such rates has been debated. Objectives To understand the hourly pattern of deliveries after spontaneous labour onset, and to compare the trajectories of the mean number of deliveries on working days with those on weekends, according to the mode of delivery. Methods Between April/2005 and August/2006, women (n =...
