O Poder do Sultão e o Estado Otomano

O estado Otomano representou um dos mais complexos sistemas políticos da história do Islão. O seu sistema burocrático e militar recorria ao recrutamento (devşirme) de não-Muçulmanos composto por crianças provenientes da Romélia para evitar que qualquer membro da sociedade Otomana interviesse na política. Sem raízes estabelecidas na sociedade Otomana a sua lealdade concentrava-se numa instituição: o Sultão. No século dezoito e dezanove o exotismo Otomano cativou muitos dos Europeus, o Sultão foi descrito como o centro da sociedade Otomana com um poder absoluto sobre todos os que a compunham. O poder do Sultão era absolutista, porém, o estado Otomano estava desenhado de uma forma em que a sua estrutura não podia ser alterada, pela sua matiz Islâmica e também para não enfraquecer as bases que mantinham a cúpula de poder. Através da metodologia de process-tracing o nosso estudo analisa a forma como o Sultão obteve e legitimou o seu poder assim como os actores que serviram de contrapeso ao seu poder. No século dezanove, particularmente, nenhum Sultão possuía um poder absoluto, a dificuldade que enfrentavam por parte da sociedade Otomana para realizar reformas mostra que não podiam agir só pela sua vontade. O nosso estudo tem como objectivo criticar Karl Marx e Max Weber, consideramos que simplificam o sistema de governação Otomano. Esperamos expor como se organizava este império como estrutura política e qual o poder do Sultão, considerando o “Círculo de Equidade” como o principal modelo para o seu poder.

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.

Numerical Method to Predict Void Formation during The Liquid Composite Molding Process

Void formation during the injection phase of the liquid composite molding process can be explained as a consequence of the non-uniformity of the flow front progression. This is due to the dual porosity within the fiber perform (spacing between the fiber tows is much larger than between the fibers within in a tow) and therefore the best explanation can be provided by a mesolevel analysis, where the characteristic dimension is given by the fiber tow diameter of the order of millimeters. In mesolevel analysis, liquid impregnation along two different scales; inside fiber tows and within the open spaces between the fiber tows must be considered and the coupling between the flow regimes must be addressed. In such cases, it is extremely important to account correctly for the surface tension effects, which can be modeled as capillary pressure applied at the flow front. Numerical implementation of such boundary conditions leads to illposing of the problem, in terms of the weak classical as well as stabilized formulation. As a consequence, there is an error in mass conservation accumulated especially along the free flow front. A numerical procedure was formulated and is implemented in an existing Free Boundary Program to reduce this error significantly.
