Um olhar interdisciplinar sobre os suplementos alimentares: reconfiguração dos papéis profissionais no contexto das novas tendências de consumo terapêutico

O actual protagonismo que os suplementos alimentares têm vindo a assumir no quadro de novas lógicas de oferta e de consumo de recursos terapêuticos, constitui um facto que é revelador da emergência de novos fenómenos que geram reconfigurações importantes ao nível da dimensão social de novas práticas em torno destes mesmos recursos, com implicações no papel dos profissionais de farmácia. Face a este novo quadro, em que novas realidades profissionais se desenham como resposta a estes fenómenos, o olhar interdisciplinar que aqui se desenvolve procura problematizar os novos papéis dos profissionais ao nível do aconselhamento e da educação para a saúde. Sustenta-se que esse objectivo dificilmente poderá ser mais do que um mero horizonte normativo, se não for capaz de integrar as abordagens de carácter sociológico sobre as importantes reconfigurações das dinâmicas de autonomia e reflexividade leiga que têm vindo a ocorrer em termos de gestão da saúde e de consumos terapêuticos. The current role that dietary supplements have been playing under new logic of supply and consumption of therapeutic resources, is a fact that reveals the emergence of new phenomena that generate major reconfigurations to the social dimension of new practices around these resources, with implications for the professional role of pharmacy practitioners. In this new framework, in which new realities are emerging as a professional response to these phenomena, the interdisciplinary outlook that we develop aims to raise some critical questions concerning the development of new roles in pharmacy practitioners in counseling and health education. We assert that this goal will scarcely be more than just a normative horizon, if unable to integrate the nature of sociological approaches on important reconfiguration of the dynamics of lay autonomy and reflexivity that have been occurring in terms of health management and therapeutic consumptions.

Railway vehicle modelling for the vehicle-track interaction compatibility analysis

Railway vehicle homologation, with respect to running dynamics, is addressed via dedicated norms. The results required, such as, accelerations and/or wheel-rail contact forces, obtained from experimental tests or simulations, must be available. Multibody dynamics allows the modelling of railway vehicles and their representation in real operations conditions, being the realism of the multibody models greatly influenced by the modelling assumptions. In this paper, two alternative multibody models of the Light Rail Vehicle 2000 (LRV) are constructed and simulated in a realistic railway track scenarios. The vehicle-track interaction compatibility analysis consists of two stages: the use of the simplified method described in the norm "UIC 518-Testing and Approval of Railway Vehicles from the Point of View of their Dynamic Behaviour-Safety-Track Fatigue-Running Behaviour" for decision making; and, visualization inspection of the vehicle motion with respect to the track via dedicated tools for understanding the mechanisms involved.

Volatility forecasting with range models: An evaluation of new alternatives to the CARR model

The aim of this paper is to analyze the forecasting ability of the CARR model proposed by Chou (2005) using the S&P 500. We extend the data sample, allowing for the analysis of different stock market circumstances and propose the use of various range estimators in order to analyze their forecasting performance. Our results show that there are two range-based models that outperform the forecasting ability of the GARCH model. The Parkinson model is better for upward trends and volatilities which are higher and lower than the mean while the CARR model is better for downward trends and mean volatilities.

Trends Of CPU, GPU and FPGA for high-performance computing

Floating-point computing with more than one TFLOP of peak performance is already a reality in recent Field-Programmable Gate Arrays (FPGA). General-Purpose Graphics Processing Units (GPGPU) and recent many-core CPUs have also taken advantage of the recent technological innovations in integrated circuit (IC) design and had also dramatically improved their peak performances. In this paper, we compare the trends of these computing architectures for high-performance computing and survey these platforms in the execution of algorithms belonging to different scientific application domains. Trends in peak performance, power consumption and sustained performances, for particular applications, show that FPGAs are increasing the gap to GPUs and many-core CPUs moving them away from high-performance computing with intensive floating-point calculations. FPGAs become competitive for custom floating-point or fixed-point representations, for smaller input sizes of certain algorithms, for combinational logic problems and parallel map-reduce problems. © 2014 Technical University of Munich (TUM).
