Foresight methodologies to understand changes in the labour process. Experience from Portugal

The foresight and scenario building methods can be an interesting reference for social sciences, especially in terms of innovative methods for labour process analysis. A scenario – as a central concept for the prospective analysis – can be considered as a rich and detailed portrait of a plausible future world. It can be a useful tool for policy-makers to grasp problems clearly and comprehensively, and to better pinpoint challenges as well as opportunities in an overall framework. The features of the foresight methods are being used in some labour policy making experiences. Case studies developed in Portugal will be presented, and some conclusions will be drawn in order to organise a set of principles for foresight analysis applied to the European project WORKS on the work organisation re-structuring in the knowledge society, and on the work design methods for new management structures of virtual organisations.

Wear resistance of TiAlSiN thin coatings

In the last decades TiAlN coatings deposited by PVD techniques have been extensively investigated but, nowadays, their potential development for tribological applications is relatively low. However, new coatings are emerging based on them, trying to improve wear behavior. TiAlSiN thin coatings are now investigated, analyzing if Si introduction increases the wear resistance of PVD films. Attending to the application, several wear test configurations has been recently used by some researchers. In this work, TiAlSiN thin coatings were produced by PVD Unbalanced Magnetron Sputtering technique and they were conveniently characterized using Scanning Electron Microscopy (SEM) provided with Energy Dispersive Spectroscopy (EDS), Atomic Force Microscopy (AFM), Electron Probe Micro-Analyzer (EPMA), Micro Hardness (MH) and Scratch Test Analysis. Properties as morphology, thickness, roughness, chemical composition and structure, hardness and film adhesion to the substrate were investigated. Concerning to wear characterization, two very different ways were chosen: micro-abrasion with ball-on-flat configuration and industrial non-standardized tests based on samples inserted in a feed channel of a selected plastic injection mould working with 30% (wt.) glass fiber reinforced polypropylene. TiAlSiN coatings with a small amount of about 5% (wt.) Si showed a similar wear behavior when compared with TiAlN reported performances, denoting that Si addition does not improve the wear performance of the TiAlN coatings in these wear test conditions.

Micro-abrasion wear behaviour of TiAlCrSiN nanostructured coatings

The injection process of glass fibres reinforced plastics promotes the moulds surface degradation by erosion. In order to improve its wear resistance, several kinds of PVD thin hard coatings were used. It is well-known that nanostructures present a better compromise between hardness and toughness. Indeed, when the coating is constituted by a large number of ultra-thin different layers, cracks and interface troubles tend to decrease. However, it is not clear that these nanostructures present a better wear behaviour in erosion processes. In order to study its wear behaviour, a sputtered PVD nanostructured TiAlCrSiN coating was used. The substrate and film surfaces topography were analyzed by profilometry and atomic force microscopy techniques. Film adhesion to the substrate was evaluated by scratch tests. The surface hardness was measured with a Vickers micro-hardness tester. The wear resistance was evaluated by micro-abrasion with a rotating ball tribometer tests. Slurry of SiC particles in distilled water was used in order to provoke the surface abrasion. Different duration tests were performed in order to analyze the wear evolution. After these tests, the wear mechanisms developed were analyzed by scanning electron microscopy. Wear craters were measured and the wear rate was calculated and discussed. With the same purpose, coated inserts were mounted in an injection mould working with a 30% glass fibres reinforced polypropylene. After 45 000 cycles no relevant wear was registered.

RESUMO - A migração transnacional de pessoas tem-se afirmado como um fenómeno global e crescente, provocando, nos diversos contextos nacionais implicados, mudança social e desafios adaptativos das sociedades e instituições. O universo da saúde poderá contudo constituir uma esfera privilegiada de interacção senão de inclusão e coesão social, requestionando os conceitos de cidadania. A sustentação de bons indicadores de saúde, nomeadamente materna e infantil, decorre de estratégias abrangentes de saúde pública e de políticas visionárias que contemplem sempre e também os mais necessitados. Procurando conhecer melhor os contextos em que ocorre o nascimento de recém-nascidos de muito baixo peso, este projecto corresponde a um estudo exploratório na maior maternidade do país, procurando entender a eventual associação de factores de índole social e familiar, nomeadamente ser de origem migrante. --------------------------- ABSTRACT - Transnational migration of people has clearly become a global and growing issue causing, on different national grounds, social change and adaptative challenges to society and its institutions. The health universe may, however, be a privileged scenery for integration and social cohesion making one re-think the concept of citizenship. Keeping up good health statistics, including maternal and child health results from wide public health strategies and fore seeking health policies not disregarding the underprivileged or the less visible fringes of society. Aiming to clarify on what context very low birth weight happens this project consists mainly in an explorative study on the biggest maternity in Portugal. Social and familiar factors are screened for possible association with migrant origin in ver
