Modern estates and the production of Lisbon’s suburbs: From the planned to the lived neighbourhood
Alto da Barra and Portela are two modern estates designed by the same architect and located on two sides of the periphery of Lisbon: the west side, Costa do Sol, where the river meets the Atlantic and the east, with no label, which is upstream. The estates were planned and built in the same period (1960s to 1970s), the height of Lisbon’s urban development. This article presents a comparative analysis of these estates: their plans, implementation, social appropriation and resilience, by exploring the sociological profile and place-attachment perceptions of their inhabitants. The analysis also contextualises the development of the estates within the consolidation of these two quite different Lisbon peripheries: the west side traditionally highly valued in relation to the east. An intensive methodology was developed—case studies of the two estates—combining quantitative (survey, inter-census analysis) and qualitative (interviews and documentary analysis) methods. In addition to the differences between the two estates, which were largely due to their specificities in terms of geographic location and status, both reveal significant feelings of place-attachment and a rejection of the suburbia label.info:eu-repo/semantics/publishedVersio
Kinetics and Mechanism of Hydrolysis of Benzimidazolylcarbamates
Synthesis of new 2-aminobenzimidazole-1-carbamates was accomplished by carbamoylation of 2-aminobenzimidazole using different substituted phenyl chloroformates.
The aqueous hydrolysis of the new compounds was examined in the pH range 1-13 at 25 oC. The evaluated kinetic parameters led to the conclusion that up to pH 4 reaction proceeds by a bimolecular attack of water to the N-protonated substrate. This is the first time this behavior
is described for carbamates, and can be ascribed to the higher basicity of the benzimidazolyl moiety when compared with the carbonyl oxygen. For higher values of pH, the results are consistent with a BAc2 mechanism with nucleophilic catalysis, but while between pH 4 and pH 7 water acts as the nucleophile, for pH> 7 the hydroxide ion is the acting species

The risk management within European equity asset managers
The objective of this research is to understand what risk management processes are currently in place amongst active European equity asset managers, and to determine which practises are most effective. The focus of this research is on active equity portfolios within the European markets. The thesis is divided in five chapters: 1) Introduction, 2) Introduction and literature of risk management in financial institutions, 3) How risk management is currently used in European funds; a survey of 200 asset managers and hedge funds is undertaken to identify current approaches to risk management, and identify what might need to be improved, chapter, 4) using a unique survey, a comprehensive analysis of the level of risk that pension fund clients (Board Members, Chief Financial Officers, and upper management of organisations with pension funds under third-party management), family offices that invest in hedge funds and Intermediate Financial Advisors (IFAs in UK) are willing to accept, and 5) Conclusions. This will cover the financial crisis and the on-going subsequent recovery. The key findings from Chapter 2 are that there is limited literature in this subject, from Chapter 3 that there is significant issues within the risk management systems utilized by the various asset managers and that there is a need to improve considerably these systems and from Chapter 4 using a unique survey we gather a comprehensive analysis of the level of risk that pension fund clients (Board Members, Chief Financial Officers, and upper management of organisations with pension funds under third-party management), family offices that invest in hedge funds and Intermediate Financial Advisors (IFAs in UK) are willing to accept.
To the best of our knowledge, this is the first comprehensive study of current risk management practices within active European equity asset managers
Efeito antimicrobiano de duas marcas comerciais de vancomicina em Staphilococcus aureus
Staphylococcus são responsáveis por um grande número de problemas médicos,
incluindo da pele e dos tecidos moles, por infecções cirúrgicas locais, endocardites e infeções
nosocomiais. Tem-se verificado um aumento da sua susceptibilidade a β-lactamicos e a
glicopeptideos o que dificulta o tratamento destas infecções
Fórum: um espaço para a construção da Autonomia na Educação a Distância
Este trabalho trata-se de uma pesquisa qualitativa em forma de estudo de caso, realizado em uma turma de graduação na modalidade semipresencial de cursos de Licenciatura em uma Universidade Federal. Investigaram-se as interações realizadas em seis fóruns no Ambiente Virtual de Aprendizagem (AVA), buscando um entendimento sobre a condução do processo de ensino-aprendizagem e os fatores que auxiliaram a fomentar a construção da autonomia do aluno. O referencial teórico que norteou o trabalho foi a Epistemologia Genética e autores atuais que estudam a Educação a Distância. Como resultados, aponta-se para a importância de propiciar espaços que possibilitam a interatividade entre os componentes e a atenção à mediação pedagógica, como um componente fundamental para auxiliar na passagem da heteronomia à autonomia
Automatic calibration of the SHETRAN hydrological modelling system using MSCE
Automatic calibration is preferred because it provides an objective and extensive searching in the feasible parameter space. In this study, the Modified Shuffled Complex Evolution (MSCE) optimization algorithm is applied to automatically calibrate the physically-based spatially-distributed hydrological model SHETRAN in the 705-km2 semi-arid Cobres basin in southern Portugal, with a spatial resolution of 2 km and a temporal resolution of 1 h. Twenty-two parameters are calibrated for the main types of land-use and soil. Nash-Sutcliffe Efficiency (NSE) is 0.86 for calibration and 0.74 for validation for basin outlet; NSE is respectively 0.65 and 0.82 for calibration, 0.69 and 0.63 for validation of internal gauging stations Albernoa and Entradas. As for storm events, NSE is 0.87 and 0.64 respectively for Storms No.1 (during the calibration period) and No.4 (during the validation period) at basin outlet; it is 0.69 and 0.65 for Storm No.4 respectively at Albernoa andEntradas. The results are satisfactory not only for basin outlet but also for internal gauging stations
Cidade do avesso
Cada cidade, tal como cada ser humano, não se repete, é única. Lisboa é única no território que ocupa e no modo como cresce, como acomoda e se acomoda a quem a usa. Ao longo do tempo, absorve os passos, as conversas, adapta-se a cada realidade nova que se lhe impõe insistindo em manter-se viva. Dentro de Lisboa, mesmo dentro, o seu cerne são os espaços escondidos. Locais de escadas e marquises onde se estende a roupa, colocam-se as caixas do ar-condicionado e os tubos infindáveis dos restaurantes, locais de arrumos onde se guarda o que é feio mas porventura útil. Onde se esquece o que já serviu.info:eu-repo/semantics/publishedVersio
Leitura da identidade territorial: uma metodologia de análise a partir do estudo de caso de Almada na área metropolitana de Lisboa
A globalização econômica e o crescimento do turismo leva regiões e cidades de características variadas a planejar e implementar estratégias para competir, seja para atrair e fixar recursos e talentos humanos ou se impulsionar como destino turístico. A promoção das cidades e territórios utiliza a valorização de seus elementos distintivos para alcançar um impacto positivo no mercado global. Neste sentido, a identidade local pode ser potencializada enquanto valor intrínseco em consonância com o desenvolvimento socioeconômico da comunidade local. Com o objetivo de se realizar um diagnóstico que identifique os elementos distintivos e contenha informação crítica para a dinamização e desenvolvimento do território, recorreu‐se a uma leitura multidimensional do território, a partir de diferentes formas de relação e prática com o mesmo, através da aplicação de uma abordagem multimétodo. O estudo de caso piloto incidiu no território compreendido pelo Eixo Cacilhas ‐ Almada Velha ‐ Cristo Rei, localizado em Almada, parte da Área Metropolitana de Lisboa. Os resultados obtidos revelam as narrativas sobre o território por diferentes pontos de vista. Os elementos indicados como distintivos são associados à paisagem, à história, às memórias, à cultura e à forma urbana.info:eu-repo/semantics/publishedVersio

Population distribution of six PCR-amplified loci in Madeira Archipelago (Portugal)
Frequency data of the short tandem repeat (STR) loci HUMTH01, HUMVWA31/A, HUMF13A1, HUMFES/FPS, D12S391 and HUMFIBRA/FGA were determined in blood stains obtained from a population of unrelated individuals from the Madeira Archipelago. The observed genotype distribution showed no significant deviation from the Hardy-Weinberg equilibrium and there was no evidence for association of alleles among the six loci. Population data showed a combined discrimination power of 0.9999998 and a chance of exclusion of 0.99597. The frequencies are similar to those of other compared caucasian populations but significant differences were found between the Madeira population and Japanese, Chinese, Greenland Eskimos and Quechua Amerindians. The six loci studied, together proved to be highly discriminating and valuable for forensic cases.http://www.sciencedirect.com/science/article/B6T6W-3W4GJ8F-8/1/69f0571183c0d939b9244a0841a1802
