A utilização do Quadro Interactivo Multimédia nas disciplinas de Português e Espanhol e o seu impacto na motivação dos alunos do Ensino Básico

O presente relatório visa, numa primeira parte, dar a conhecer o processo de integração do Quadro Interativo Multimédia (QIM) nas escolas portuguesas, destacando, para tal, o contributo do Plano de Educação Tecnológica, quer no aumento da rede de infraestruturas, quer na formação de professores e criação de recursos educativos digitais (RED). Apresentando as potencialidades desta ferramenta educativa, avaliam-se as vantagens, desvantagens e o impacto da sua utilização na motivação e aprendizagem dos estudantes, segundo a mais recente literatura. Abordam-se diferentes utilizações do QIM nas aulas de Português, em particular o ensino da gramática através deste recurso, e nas aulas de Espanhol/LE, através da exploração de pequenas unidades didáticas interativas concebidas especificamente para o QIM. Numa segunda parte, apresenta-se o Colégio Sra. da Boa Nova, onde foi realizada a Prática de Ensino Supervisionada (PES) e uma caracterização das turmas em que foram lecionadas as aulas práticas de Português e de Espanhol/LE. Por fim, apresentam-se as atividades que foram desenvolvidas, em particular com o QIM, durante a lecionação.

Search-for-yield in Portuguese fixed-income mutual funds and monetary policy

This paper studies the effects of monetary policy on mutual fund risk taking using a sample of Portuguese fixed-income mutual funds in the 2000-2012 period. Firstly I estimate time-varying measures of risk exposure (betas) for the individual funds, for the benchmark portfolio, as well as for a representative equally-weighted portfolio, through 24-month rolling regressions of a two-factor model with two systematic risk factors: interest rate risk (TERM) and default risk (DEF). Next, in the second phase, using the estimated betas, I try to understand what portion of the risk exposure is in excess of the benchmark (active risk) and how it relates to monetary policy proxies (one-month rate, Taylor residual, real rate and first principal component of a cross-section of government yields and rates). Using this methodology, I provide empirical evidence that Portuguese fixed-income mutual funds respond to accommodative monetary policy by significantly increasing exposure, in excess of their benchmarks, to default risk rate and slightly to interest risk rate as well. I also find that the increase in funds’ risk exposure to gain a boost in return (search-for-yield) is more pronounced following the 2007-2009 global financial crisis, indicating that the current historic low interest rates may incentivize excessive risk taking. My results suggest that monetary policy affects the risk appetite of non-bank financial intermediaries.

Espírito Santo Saúde: The bidding war

This case study describes the current situation of Espírito Santo Saúde, which involved an eventful takeover process. The company initially went public on February 2014 and later that year, due to the financial situation of its holdings it had to be sold. The bidding war began in August 2014, after Ángeles announced the first offer. Other participants who also pitched bids include José de Mello Saúde, UnitedHealth and Fosun. Furthermore, the potential projects Espírito Santo Saúde was considering implementing prior to the sale and the current situation of the healthcare industry in Portugal, will also be analysed.

Genome-scale metabolic network reconstruction of Polaromonas sp. strain JS666: analysis of cDCE degradation rates and design of experiments for bioremediation improvement

Release of chloroethene compounds into the environment often results in groundwater contamination, which puts people at risk of exposure by drinking contaminated water. cDCE (cis-1,2-dichloroethene) accumulation on subsurface environments is a common environmental problem due to stagnation and partial degradation of other precursor chloroethene species. Polaromonas sp. strain JS666 apparently requires no exotic growth factors to be used as a bioaugmentation agent for aerobic cDCE degradation. Although being the only suitable microorganism found capable of such, further studies are needed for improving the intrinsic bioremediation rates and fully comprehend the metabolic processes involved. In order to do so, a metabolic model, iJS666, was reconstructed from genome annotation and available bibliographic data. FVA (Flux Variability Analysis) and FBA (Flux Balance Analysis) techniques were used to satisfactory validate the predictive capabilities of the iJS666 model. The iJS666 model was able to predict biomass growth for different previously tested conditions, allowed to design key experiments which should be done for further model improvement and, also, produced viable predictions for the use of biostimulant metabolites in the cDCE biodegradation.
