Are societal changes new? Questions or trends and future perceptions on knowledge-based economy

With the emergence of a global division of labour, the internationalisation of markets and cultures, the growing power of supranational organisations and the spread of new information technologies to every field of life, it starts to appear a different kind of society, different from the industrial society, and called by many as ‘the knowledge-based economy’, emphasizing the importance of information and knowledge in many areas of work and organisation of societies. Despite the common trends of evolution, these transformations do not necessarily produce a convergence of national and regional social and economic structures, but a diversity of realities emerging from the relations between economic and political context on one hand and the companies and their strategies on the other. In this sense, which future can we expect to the knowledge economy? How can we measure it and why is it important? This paper will present some results from the European project WORKS – Work organisation and restructuring in the knowledge society (6th Framework Programme), focusing the future visions and possible future trends in different countries, sectors and industries, given empirical evidences of the case studies applied in several European countries, underling the importance of foresight exercises to design policies, prevent uncontrolled risks and anticipate alternatives, leading to different ‘knowledge economies’ and not to the ‘knowled

Global and Partitioned Multiprocessor Fixed Priority Scheduling with Deferred Pre-emption

This article introduces schedulability analysis for global fixed priority scheduling with deferred preemption (gFPDS) for homogeneous multiprocessor systems. gFPDS is a superset of global fixed priority pre-emptive scheduling (gFPPS) and global fixed priority non-pre-emptive scheduling (gFPNS). We show how schedulability can be improved using gFPDS via appropriate choice of priority assignment and final non-pre-emptive region lengths, and provide algorithms which optimize schedulability in this way. Via an experimental evaluation we compare the performance of multiprocessor scheduling using global approaches: gFPDS, gFPPS, and gFPNS, and also partitioned approaches employing FPDS, FPPS, and FPNS on each processor.

Convergence of Smart Grid ICT architectures for the last mile

The evolution of the electrical grid into a smart grid, allowing user production, storage and exchange of energy, remote control of appliances, and in general optimizations over how the energy is managed and consumed, is also an evolution into a complex Information and Communication Technology (ICT) system. With the goal of promoting an integrated and interoperable smart grid, a number of organizations all over the world started uncoordinated standardization activities, which caused the emergence of a large number of incompatible architectures and standards. There are now new standardization activities which have the goal of organizing existing standards and produce best practices to choose the right approach(es) to be employed in specific smart grid designs. This paper follows the lead of NIST and ETSI/CEN/CENELEC approaches in trying to provide taxonomy of existing solutions; our contribution reviews and relates current ICT state-of-the-art, with the objective of forecasting future trends based on the orientation of current efforts and on relationships between them. The resulting taxonomy provides guidelines for further studies of the architectures, and highlights how the standards in the last mile of the smart grid are converging to common solutions to improve ICT infrastructure interoperability.

Pseudo Phase Plane and Fractional Calculus Modelling of Western Global Economic Downturn

This paper applies Pseudo Phase Plane (PPP) and Fractional Calculus (FC) mathematical tools for modeling world economies. A challenging global rivalry among the largest international economies began in the early 1970s, when the post-war prosperity declined. It went on, up to now. If some worrying threatens may exist actually in terms of possible ambitious military aggression, invasion, or hegemony, countries’ PPP relative positions can tell something on the current global peaceful equilibrium. A global political downturn of the USA on global hegemony in favor of Asian partners is possible, but can still be not accomplished in the next decades. If the 1973 oil chock has represented the beginning of a long-run recession, the PPP analysis of the last four decades (1972–2012) does not conclude for other partners’ global dominance (Russian, Brazil, Japan, and Germany) in reaching high degrees of similarity with the most developed world countries. The synergies of the proposed mathematical tools lead to a better understanding of the dynamics underlying world economies and point towards the estimation of future states based on the memory of each time series.

Analysis of World Economic Variables Using Multidimensional Scaling

Waves of globalization reflect the historical technical progress and modern economic growth. The dynamics of this process are here approached using the multidimensional scaling (MDS) methodology to analyze the evolution of GDP per capita, international trade openness, life expectancy, and education tertiary enrollment in 14 countries. MDS provides the appropriate theoretical concepts and the exact mathematical tools to describe the joint evolution of these indicators of economic growth, globalization, welfare and human development of the world economy from 1977 up to 2012. The polarization dance of countries enlightens the convergence paths, potential warfare and present-day rivalries in the global geopolitical scene.

Fractional State Space Analysis of Economy Systems

This paper examines modern economic growth according to the multidimensional scaling (MDS) method and state space portrait (SSP) analysis. Electing GDP per capita as the main indicator for economic growth and prosperity, the long-run perspective from 1870 to 2010 identifies the main similarities among 34 world partners’ modern economic growth and exemplifies the historical waving mechanics of the largest world economy, the USA. MDS reveals two main clusters among the European countries and their old offshore territories, and SSP identifies the Great Depression as a mild challenge to the American global performance, when compared to the Second World War and the 2008 crisis.

Competências transversais dos recém-diplomados do ensino superior no mercado global

O mercado de trabalho está a mudar rapidamente e de muitas formas, nomeadamente, a revolução das tecnologias de informação e comunicação, a globalização, a flexibilização e as alterações da estrutura do trabalho, que conduzem a uma crescente imprevisibilidade e à necessidade de lidar com este contexto de incerteza. Estas mudanças, inevitavelmente, têm implicações no conjunto de competências necessárias para que os trabalhadores sejam capazes de funcionar adequadamente num mercado global cada vez mais competitivo e em constante mutação. Desta forma, nos dias de hoje, o mercado de trabalho requer mais do que conhecimentos teóricos e técnicos, reclama por um conjunto de competências transversais que servirão de suporte e ligação entre o conhecimento técnico e a prática profissional. É neste cenário que emergem as competências transversais que cada vez mais assumem uma importância maior. O objetivo deste estudo consiste em identificar as competências transversais requeridas aos recém-diplomados do ensino superior no mercado global. Inicialmente, analisa-se o conceito de competência transversal, apresentando algumas definições e assinalando as suas características comuns, destacando ainda a variedade de designações utilizadas para as nomear. No âmbito do estudo foi realizada revisão da literatura nacional e internacional sobre as competências transversais nos diplomados, quer na perspetiva dos próprios diplomados, quer dos empregadores. Através da análise de conteúdo, foram identificadas as competências transversais mais valorizadas por continente e, a partir da análise das mesmas, definiram-se as competências transversais exigidas no mercado global. Finalmente são discutidas as implicações teóricas e empíricas das conclusões deste trabalho.

Efeitos da técnica Stretching Global Ativo na flexibilidade em nadadores de alta competição

Introdução: A flexibilidade é uma qualidade física importante na prática da natação, pois a qualidade da execução de inúmeros movimentos depende diretamente do grau de mobilidade das articulações envolvidas. Objetivo(s): Analisar o efeito da flexibilidade proporcionado pelo método Stretching Global Ativo (SGA) em nadadores de alta competição. Métodos: Foram incluídos 30 nadadores de alta competição, divididos em dois grupos: um grupo de controlo (GC) e um grupo experimental (GE). No GE foi aplicado posturas segundo o método SGA, ao longo de 20 semanas. Em todos os nadadores avaliou-se o flexiteste, o teste da extensão do tronco e o teste 3º dedo ao solo. Resultados: Verificou-se um aumento significativo dos níveis de flexibilidade na cadeia posterior e nos valores do flexiteste no GE face ao GC (p≤0,05). Na cadeia anterior não foram identificadas diferenças significativas em nenhum momento. Conclusão: Com a utilização de um protocolo de treino de SGA obteve-se um aumento da flexibilidade da cadeia posterior e dos valores do flexiteste.
