O Congresso Português de Sociologia e as tendências de evolução da sociologia da saúde em Portugal

Nesta comunicação de abertura da área temática de Sociologia da Saúde, procede-se a uma breve reflexão acerca das tendências relativas à produção sociológica que se vai realizando em Portugal no domínio da saúde, tomando como ponto de partida os trabalhos apresentados nas diferentes edições do Congresso Português de Sociologia. A reflexão decorre em torno de cinco tendências centrais: tendência para o crescimento (1), para a maior diversidade temática (2), para o rejuvenescimento (3), para a escassa reflexão em torno das práticas profissionais dos sociólogos (4) e para a internacionalização (5).

Market trends and dilemmas of parenthal participation in schools

Este artigo descreve e analisa o impacto da definição e implementação de um novo modelo de gestão dos estabelecimentos de ensino não superior (Dec-lei nº115_A/98) nos padrões de cidadania e equidade do ensino público Português. A institucionalização deste modelo representa uma mudança na matriz centralista e burocrática do referido ensino público e sugere uma aproximação às concepções neo-gerencialistas e neo-liberais que, desde meados dos anos 80, têm dominado a agenda política de muitos países desenvolvidos e de alguns organismos internacionais. Os resultados da pesquisa sugerem que a implementação do novo modelo de gestão contribuiu para reforçar os padrões de diferenciação social no ensino básico (1ºciclo) e, mais especificamente, para preservar as .vantagens competitivas. da classe média na escola pública Portuguesa.

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.

Trends in properties of para-substituted 3-(phenylhydrazo)pentane-2,4-diones

Trends between the Hammett's sigma(p) and related normal sigma(n)(p), inductive sigma(I), resonance sigma(R), negative sigma(-)(p) and positive sigma(+)(p) polar conjugation and Taft's sigma(o)(p) substituent constants and the N-H center dot center dot center dot O distance, delta(N-H) NMR chemical shift, oxidation potential (E-p/2(ox), measured in this study by cyclic voltammetry (CV)) and thermodynamic parameters (pK, Delta G(0), Delta H-0 and Delta S-0) of the dissociation process of unsubstituted 3-(phenylhydrazo)pentane-2,4-dione (HL1) and its para-substituted chloro (HL2), carboxy (HL3), fluoro (HL4) and nitro (HL5) derivatives were recognized. The best fits were found for sigma(p) and/or sigma(-)(p) in the cases of d(N center dot center dot center dot O), delta(N-H) and E-p/2(ox), showing the importance of resonance and conjugation effects in such properties, whereas for the above thermodynamic properties the inductive effects (sigma(I)) are dominant. HL2 exists in the hydrazo form in DMSO solution and in the solid state and contains an intramolecular H-bond with the N center dot center dot center dot O distance of 2.588(3)angstrom. It was also established that the dissociation process of HL1-5 is non-spontaneous, endothermic and entropically unfavourable, and that the increase in the inductive effect (sigma(I)) of para-substitutents (-H < -Cl < -COOH < -F < -NO2) leads to the corresponding growth of the N center dot center dot center dot O distance and decrease of the pK and of the changes of Gibbs free energy, of enthalpy and of entropy for the HL1-5 acid dissociation process. The electrochemical behaviour of HL1-5 was interpreted using theoretical calculations at the DFT/HF hybrid level, namely in terms of HOMO and LUMO compositions, and of reactivities induced by anodic and cathodic electron-transfers.

Pulmonary tuberculosis in Continental Portugal 2000-2010: temporal trends clustering as a tool for control evaluation

Clustering analysis is a useful tool to detect and monitor disease patterns and, consequently, to contribute for an effective population disease management. Portugal has the highest incidence of tuberculosis in the European Union (in 2012, 21.6 cases per 100.000 inhabitants), although it has been decreasing consistently. Two critical PTB (Pulmonary Tuberculosis) areas, metropolitan Oporto and metropolitan Lisbon regions, were previously identified through spatial and space-time clustering for PTB incidence rate and risk factors. Identifying clusters of temporal trends can further elucidate policy makers about municipalities showing a faster or a slower TB control improvement.

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).
