Synthesis about a collaborative project on “Technology Assessment of Autonomous System

The project started in 2009 with the support of DAAD in Germany and CRUP in Portugal under the “Collaborative German-Portuguese University Actions” programme. One central goal is the further development of a theory of technology assessment applied to robotics and autonomous systems in general that reflects in its methodology the changing conditions of knowledge production in modern societies and the emergence of new robotic technologies and of associated disruptive changes. Relevant topics here are handling broadened future horizons and new clusters of science and technology (medicine, engineering, interfaces, industrial automation, micro-devices, security and safety), as well as new governance structures in policy decision making concerning research and development (R

Estudo da eficiência da ETAR da zona industrial da AutoEuropa por análise biológica

No tratamento de águas residuais por lamas activadas, existem diferentes populações de protozoários e metazoários que se podem desenvolver durante o processo. A sua presença é fundamental para o bom desempenho da ETAR. Além de reduzirem a turvação do efluente final, estimulam o crescimento bacteriano, promovem a floculação e algumas espécies reduzem a poluição. É possível estabelecer uma estreita relação entre a predominância de determinadas espécies ou grupos de espécies, com parâmetros operacionais da ETAR, tais como os índices bióticos. Este procedimento requer a identificação e enumeração das diferentes espécies. No entanto, existem outros métodos, que apresentam relações entre a abundância de uma dada espécie ou grupo e os parâmetros da estação. O presente trabalho tem como objectivos: avaliar o funcionamento do sistema de tratamento de lamas activadas através da observação microscópica de protozoários e metazoários, identificação e contagem das espécies relevantes; estabelecer relações entre os organismos que contribuem para o processo de depuração de águas residuais e as condições de operação, como parâmetros físicoquímicos ou o desempenho da ETAR; e produzir uma ferramenta de apoio à gestão da ETAR, baseada em princípios biológicos. Pretende-se, ainda, contribuir e incentivar para a adopção de metodologias semelhantes em outros sistemas de lamas activadas em funcionamento no nosso País. Em termos metodológicos, a colheita de amostras foi realizada semanalmente na ETAR da ZIA durante dois meses e meio. Os parâmetros operacionais e físico-químicos foram obtidos junto da ETAR. A análise biológica foi efectuada por microscopia óptica. Avaliou-se qualitativa e quantitativamente a microfauna presente no tanque de arejamento, no poço de mistura de lamas e no clarificado de ambos os decantadores, a fim de se verificar as possíveis correlações desses parâmetros com a eficiência do sistema. Aplicou-se os resultados biológicos obtidos, em quatro modelos propostos para a avaliação do processo de tratamento, baseada em análises biológicas. Em termos qualitativos e na maior parte das observações, a lama apresentou boa qualidade. A ETAR da ZIA foi colonizada por tecamebas, principalmente Arcella sp. e Euglypha alveolata, em todo, o estudo e em todos os pontos analisados. No tanque de arejamento foram sempre observados ciliados nadadores livres. A densidade total de organismos no tanque de arejamento variou de 2982 e 7330 organismos/mL, com valor médio de 5995 organismos/mL. Relativamente, aos parâmetros estudados, os objectivos de remoção para o CBO5, CQO, SST e SSV foram alcançados.

The sociological perspective on the knowledge-based society: assumptions, facts and visions

The paper will present the central discourse of the knowledge-based society. Already in the 1960s the debate of the industrial society already raised the question whether there can be considered a paradigm shift towards a knowledge-based society. Some prominent authors already foreseen ‘knowledge’ as the main indicator in order to displace ‘labour’ and ‘capital’ as the main driving forces of the capitalistic development. Today on the political level and also in many scientific disciplines the assumption that we are already living in a knowledge-based society seems obvious. Although we still do not have a theory of the knowledge-based society and there still exist a methodological gap about the empirical indicators, the vision of a knowledge-based society determines at least the perception of the Western societies. In a first step the author will pinpoint the assumptions about the knowledge-based society on three levels: on the societal, on the organisational and on the individual level. These assumptions are relied on the following topics: a) The role of the information and communication technologies; b) The dynamic development of globalisation as an ‘evolutionary’ process; c) The increasing importance of knowledge management within organisations; d) The changing role of the state within the economic processes. Not only the differentiation between the levels but also the revision of the assumptions of a knowledge-based society will show that the ‘topics raised in the debates’ cannot be considered as the results of a profound societal paradigm shift. However what seems very impressive is the normative and virtual shift towards a concept of modernity, which strongly focuses on the role of technology as a driving force as well as on the global economic markets, which has to be accepted. Therefore – according to the official debate - the successful adaptation of these processes seems the only way to meet the knowledge-based society. Analysing the societal changes on the three levels, the label ‘knowledge-based society’ can be seen critically. Therefore the main question of Theodor W. Adorno during the 16th Congress of Sociology in 1968 did not loose its actuality. Facing the societal changes he asked whether we are still living in the industrial society or already in a post-industrial state. Thinking about the knowledge-based society according to these two options, this exercise would enrich the whole debate in terms of social inequality, political, economic exclusion processes and at least the power relationship between social groups.

Ergonomics and Usability – key factors in Knowledge Society

During the recent years human society evolved from the “industrial society age” and transitioned into the “knowledge society age”. This means that knowledge media support migrated from “pen and paper” to computer-based Information Systems. Due to this fact Ergonomics has assumed an increasing importance, as a science/technology that deals with the problem of adapting the work to the man, namely in terms of Usability. This paper presents some relevant Ergonomics, Usability and User-centred design concepts regarding Information Systems.

The transformation of work? A quantitative evaluation of changes in work in Portugal

This report is made for the Work Package 15 of WORKS project and tries to develop more information on the Portuguese situation in the work structures changes in the recent years. It starts with an analysis of socio- economical indicators (Macro economical indicators, Employment indicators, Consumption, Technology at the workplace, Productivity), and then approaches the situation in terms of work flexibility in its dimensions of time use and New forms of work organisation. It traces employment in business functions with a sectoral and occupational approach, and analyses the occupational change in South Europe with particular relevance to Portugal (skill utilisation and job satisfaction, occupational and industrial mobility, quantitative evaluation of the shape of employment in Europe. Finaly are analysed the globalisation indicators.
