Lexicultura na Língua Chinesa e na Lexicografia Bilingue de Chinês-Português

No contexto de internacionalização de hoje, acompanhando os contactos cada vez mais intensos entre o mundo chinês e o mundo lusófono, é exigida a maior atenção à questão da lexicultura na comunicação interlingual e intercultural, pois o que preocupa as partes envolvidas não é apenas descodificar os signos meramente linguísticos, mas também perceber a cultura que a língua, nomeadamente as unidades lexicais transportam, visando um comportamento culturalmente correto e adequado nessa comunicação. Partindo desta preocupação, este trabalho tenta, através da abordagem e análise da língua, da escrita e do léxico chineses, comprovar que o chinês, devido às suas peculiaridades inexistentes em outras línguas do mundo, constitui o vivo exemplo que exemplifica e alarga o conceito de lexicultura, pois a própria língua, sobretudo a sua escrita e as suas unidades lexicais, além de refletirem a cultura popular e partilhada, também contam verdadeiras histórias da Humanidade e da China. Baseando-se nesta abordagem e análise, a tese apresenta um novo modelo de dicionário cultural chinês-português, com propostas concretas de seleção de vedetas para a sua macroestrutura e de definição de vedetas na sua microestrutura, ao serviço da comunicação entre os dois mundos em questão.

Southern modernisms from A to Z and back again

The book now being published results from a research project entitled Southern Modernisms that ran from March 2014 to May 2015 with FCT funding. The aim of the project was to explore the possibility of constructing a more inclusive, plural notion of modernism through the revision of Modernism’s prevailing definition – its stylistic focus, its formalist and anti-representative bias, as well as its autonomic assumptions, or, as far as architecture is concerned, its functionalist credo. This critical undertaking was grounded on the hypothesis that southern European modernisms featured a strong entrenchment in popular culture (folk art and vernacular architecture), and that this characteristic could be understood as anticipating some of the premises of, what would later become known as, critical regionalismo.

Transport mechanism in ionic liquid membranes and the study of thiomersal biodegradation

The initial goal of this work was the development of a supported liquid membrane (SLM) bioreactor for the remediation of vaccine production effluents contaminated with a highly toxic organomercurial – thiomersal. Therefore, two main aspects were focused on: 1) the development of a stable supported liquid membrane – using room temperature ionic liquids (RTILs) – for the selective transport of thiomersal from the wastewater to a biological compartment, 2) study of the biodegradation kinetics of thiomersal to metallic mercury by a Pseudomonas putida strain. The first part of the work focused on the evaluation of the physicochemical properties of ionic liquids and on the SLMs’ operational stability. The results obtained showed that, although it is possible to obtain a SLM with a high stability, water possesses nonnegligible solubility in the RTILs studied. The formation of water clusters inside the hydrophobic ionic liquid was identified and found to regulate the transport of water and small ions. In practical terms, this meant that, although it was possible to transport thiomersal from the vaccine effluent to the biological compartment, complete isolation of the microbial culture could not be guaranteed and the membrane might ultimately be permeable to other species present in the aqueous vaccine wastewater. It was therefore decided not to operate the initially targeted integrated system but, instead, the biological system by itself. Additionally, attention was given to the development of a thorough understanding of the transport mechanisms involved in the solubilisation and transport of water through supported liquid membranes with RTILs as well as to the evaluation of the effect of water uptake by the SLM in the transport mechanisms of water-soluble solutes and its effect on SLM performance. The results obtained highlighted the determinant role played by water – solubilised inside the ionic liquids – on the transport mechanism. It became clear that the transport mechanism of water and water-soluble solutes through SLMs with [CnMIM][PF6] RTILs was regulated by the dynamics of water clusters inside the RTIL, rather than by molecular diffusion through the bulk of the ionic liquid. Although the stability tests vi performed showed that there were no significant losses of organic phase from the membrane pores, the formation of water clusters inside the ionic liquid, which constitute new, non-selective environments for solute transport, leads to a clear deterioration of SLM performance and selectivity. Nevertheless, electrical impedance spectroscopy characterisation of the SLMs showed that the formation of water clusters did not seem to have a detrimental effect on the SLMs’ electrical characteristics and highlighted the potential of using this type of membranes in electrochemical applications with low resistance requirements. The second part of the work studied the kinetics of thiomersal degradation by a pure culture of P. putida spi3 strain, in batch culture and using a synthe tic wastewater. A continuous ly stirred tank reactor fed with the synthetic wastewater was also operated and the bioreactor’s performance and robustness, when exposed to thiomersal shock loads, were evaluated. Finally, a bioreactor for the biological treatment of a real va ccine production effluent was set up and operated at different dilution rates. Thus it was possible to treat a real thiomersal-contaminated effluent, lowering the outlet mercury concentration to values below the European limit for mercury effluent discharges.

Changing representations and practices in school mathematics: the case of Modern Math in Portugal

The curricular movement known as Modern Mathematics aimed at the transformation of representations and practices in school mathematics. Its study provides us with ways of understanding how these changes came about. The purpose of this paper is to contribute to the understanding of the ways in which representations of school mathematics gradually were influenced by ideas from the Modern Mathematics movement, how these new ideas merged into local educational traditions, and how they were transformed into meaningful practice. This work is centred on the Portuguese context from the middle 1950s to the middle 1960s, and builds on Chervel’s notion of school culture and Gruzinski’s discussion of connected histories.
