International Conference on “Foresight Studies on Work in the Knowledge Society“ in Monte de Caparica (FCT-UNL) on 19-20 October 2006

On 19 and 20 October 2006, the Research Centre on Enterprise and Work Organisation (IET) organised the first international conference on “Foresight Studies on Work in the Knowledge Society”. It took place at the auditorium of the new Library of FCT-UNL and had the support of the research project “CodeWork@VO” (financed by FCT-MCTES and co-ordinated by INESC, Porto). The conference related to the European research project “Work Organisation and Restructuring in the Knowledge Society” (WORKS), which is financed by the European Commission. The main objective of the conference was to analyse and discuss research findings on the trends of work structures in the knowledge society, and to debate on new work organisation models and new forms of work supported by ICT.

Fiscal dynamics and electoral behavior in the Eurozone

Abstract: The Stability Growth Pact and the 3% rule did not prevent countries from running large deficits. Countries in the EMU administrate fiscal policies differently, despite the existence of a common quantitative goal. The main focus of this work project is to study differences in the fiscal dynamics of eight EMU countries and assess the role of political variables in shaping those dynamics. We find that elections negatively affect government revenue in Austria, Belgium, Portugal, Spain and Germany. Expenditure, on the other hand, responds positively to incoming elections in Portugal, Italy, France and Netherlands, and negatively in the case of Germany.

Anti-apolipoprotein A-I antibodies in the pathogenesis of Alzheimer disease : project plan

RESUMO: A doença de Alzheimer (AD) é a forma mais comum de demência em todo o mundo e sua prevalência deverá duplicar até 2050. Os mecanismos precisos responsáveis pela AD são desconhecidas mas as características histopatológicas estão bem caracterizadas. A hipótese mais importante para a perda neuronal e declínio cognitivo na AD é a cascata amilóide que indica que AD é o resultado da sobreprodução de beta amilóide (Aβ) e / ou remoção ineficaz; a acumulação do BA no cérebro seria o passo crítico na patogénese da AD. Actualmente, a identificação de proteínas que se ligam ao Aβ e modulam a sua agregação e neurotoxicidade pode proporcionar a base para novas abordagens terapêuticas. A apolipoproteína AI (ApoA-I), o principal componente das HDL humanas, interage com o domínio extracelular da proteína precursora de amilóide (APP), bem como com o Aβ. Estudos epidemiológicos têm mostrado uma diminuição acentuada da ApoA-I plasmática em doentes com AD, com uma correlação inversa entre o nível de ApoA-I e o risco de AD. Este trabalho pretende apresentar um projecto que tem como objectivo investigar se os anticorpos anti-apo AI podem impedir a formação de complexos Aβ / ApoA-I, bloqueando o efeito protector da ApoA-I. A hipótese baseia-se na possibilidade dos doentes com AD terem anticorpos anti-ApoA-I plasmáticos e de estes poderem interferir com a formação do complexo no LCR.------- ABSTRACT:Alzheimer’s disease (AD) is the most common form of dementia world-wide and its prevalence is expected to double by the year 2050. The precise mechanisms responsible for AD are unknown but the histopathologic features are well-characterised. The most compelling hypothesis for neuronal loss and cognitive decline in AD is the amyloid cascade hypothesis which states that AD is the result of amyloid beta (Aβ) overproduction and/or ineffective clearance and its accumulation in the brain would be the critical step in AD pathogenesis. Currently, identification of proteins that bind Aβ and modulate its aggregation and neurotoxicity could provide the basis for novel treatment approaches. Apolipoprotein A-I (ApoA-I), the main constituent of human HDL, ApoA-I interacts with the extracellular domain of amyloid precursor protein (APP), as well as with Aβ itself. Epidemiological studies have shown a marked decrease of plasma ApoA-I levels in AD patients, with an inverse correlation between the ApoA-I level and the risk of AD. This work intends to present a project that aims to investigate if anti-ApoA-I antibodies may prevent the formation of the Aβ /ApoA-I complex and by doing so blocking the protective effect of ApoA-I in AD. We base the hypothesis on the possibility that patients with AD might have anti-ApoA-I antibodies in plasma and that these can interfere with the complex formation in the cerebrospinal fluid (CSF).

Development of a fundus camera for analysis of photoreceptor directionality in the healthy retina

The Stiles-Crawford effect (SCE) is the well-known phenomenon in which the brightness of light perceived by the human eye depends upon its entrance point in the pupil. This physiological characteristic is due to the directional sensitivity of the cone photoreceptors in the retina and it displays an approximately Gaussian dependency which is altered in a number of pathologies. Retinal imaging, a widely spread clinical practice, may be used to evaluate the SCE and thus serve as diagnostic tool. Nonetheless, its use for such a purpose is still underdeveloped and far from the clinical reality. In this project a fundus camera was built and used to assess the cone photoreceptor directionality by reflective imaging of the retina in healthy individuals. The physical and physiological implications of its development are addressed in detail in the text: the optical properties of the human eye, illumination issues, acquiring a retinal image formed by the eye, among others. A full description of the developmental process that led to the final measuring method and results is also given. The developed setup was successfully used to obtain high quality images of the eye fundus and in particular the parafoveal cone photoreceptors. The SCE was successfully observed and characterized. Even though considerable improvements could be done to the measurement method, the project showed the feasibility of using retinal imaging to evaluate the SCE thus motivating its usage in a clinical environment.

Context costs and comparative advantages in the telecommunications sector in Portugal and China

This Work Project aims to discuss the Context Costs and Comparative Advantages of the Telecommunications sector both in Portugal and China. The work was built mostly on primary research by interviews with relevant people (business persons, University Professors and Agencies directors), and by economic data publicly available. A list of context costs and comparative advantages was drawn for each country and possible resolutions suggestions were made in the end. The context costs depend heavily on the economic situation of the countries and it should be taken into account when assessing the degree of magnitude of each cost of context. The competitive advantages of each country were drawn in comparison with one another. Some key results stand out: firstly, Portugal’s costs of context depend mainly on governmental decisions, uncertainties and instability and China’s cost of context depend primarily on cultural norms, mainly the Guanxi; second, the telecommunications sector shares most of its context costs and advantages with other sectors; third, China as an economic power could use the telecommunications sector as a way to further develop and boost its economy.
