The first attempts to apply geophysical methods to archaeological sites in Portugal date from the mid-sixties of the last century. Since then, geophysical methods have been used more and more frequently to help on archaeological site recognition, delineating buried structures, and help on excavating strategies. The first geophysical methods used in Portugal were geoelectrical methods followed by magnetic methods; today those two methods are still used; however, georadar and electrical resistivity tomography have also been used on a routine basis whenever the local conditions allow their use. Four archaeological sites will be described as examples on the use of geophysical methods in Archaeology. Two of them are from roman times (the Roman Villa of Tourega, in central Portugal and the Roman town of Troia, in the west coast of Portugal), one is from Neolithic times (a burial mound in central Portugal); the last one is a recent archaeological site (eighteenth century) and has to do with the location of a crypt known to exist in the garden of the Portuguese Legislature in Lisbon. Only electrical resistivity tomography and georadar were used. The sites were chosen because in all of them there were already previously excavated areas or there were plans for future excavation. When choosing those sites the idea was to be able to compare the interpretations of the geophysical data with the results of the excavations.

O presente artigo documenta os fatos históricos ocorridos na segunda metade do século XIX em Cabo Delgado e Niassa no norte de Moçambique. A pesquisa realizada entre os anos de 2010 e 2011 incidiu sobre a documentação dos fundos do governo-geral de Moçambique e do governo do Distrito de Cabo Delgado do Arquivo Histórico de Moçambique (AHM). Constam no artigo os expedientes portugueses referentes a disputa entre Zanzibar e Portugal sobre a fronteira norte de Moçambique em Cabo Delgado e ao Tratado de Comércio e Amizade celebrado entre os dois governos. Constam também expedientes sobre a "Expedição ao Niassa", os diferendos que se desenvolveram entre autoridades portuguesas de Moçambique e autoridades inglesas da África Central Britânica (Niassalândia, hoje Malawi) e sobre as lutas de resistência em Niassa.

Mestrado em Finanças ; Numa sociedade onde o número de pensionistas está a aumentar e a proporção de contribuintes a decrescer, o sistema da segurança social está a tornar-se insustentável, aumentando assim a importância dos planos poupança reforma como complemento das pensões pagas pelo Estado. Após a crise financeira de 2008, cresceu a preocupação em garantir um rendimento durante a reforma, levando a um aumento da contribuição para produtos de longo-prazo. Esta dissertação tem como objetivo analisar o desempenho dos planos poupança reforma (PPR) em Portugal e providenciar mais informação sobre este tópico, uma vez que a literatura nesta área é escassa. Os resultados sugerem que o retorno destes planos não é significativamente diferente de zero e os mesmos têm um desempenho inferior, a portfólios equivalentes, em média. Este resultado pode implicar que os PPR não são a melhor solução a fim de garantir o mesmo nível de vida durante a reforma do indivíduo. Quando comparados entre si, os PPR apresentam uma rendibilidade semelhantes, o que pode ser provocado pelas restrições impostas por lei no que concerne à estrutura do mercado de fundos de pensões e à alocação dos investimentos. ; In a society where the number of pensioners is considerably increasing and the proportion of contributors is decreasing, the social security system is becoming unaffordable, increasing the importance of personal pension plans in complementing the pensions provided by Governments. After the 2008 financial crisis, the concern related with the guarantee of an income during the retirement period increased, which lead to a major investment in retirement-oriented financial products. This work pretends to analyze the performance of personal pension plans in Portugal and to provide more information about these financial products, as the literature in Portugal related with this topic is scarce. It was found evidence that, on average, the performance of these plans is not significantly different from zero and that they underperform their benchmarks. This result might implicate that these plans are not the solution to guarantee the same standard of living once the individual retires. When compared against each other, the performance does not differ significantly between funds, and this might be related with the restrictions imposed by the Government regarding the market structure and asset allocation. ; info:eu-repo/semantics/publishedVersion

We present an analysis of the main orientations that have guided the introduction of the New Public Management principles in the Portuguese health sector. Despite of being a result of international dynamics we also equate some national institutional characteristics such as a delayed and unfinished Welfare State and a centralized structure in political decision making that configures in a particular way the Portuguese health sector reform. Five main dynamics are here identified: dece ntralization of competences, financing and accountability, rationalization of expenses, deregulation of the labour market and internal competition and differentiation in the NHS. One of the most important arguments that we stress is that the health reform pursued in Portugal over the last decades has followed an ideological convergence despite today's growing uncertainties about the f uture of the Portuguese NHS, moving between Beveridge and Bismarck principles and dealing with an emergent for-profit sector that is allowed to act in competition with public sector.

O presente artigo apresenta uma análise sobre o contexto das lutas armadas de independência nacional na África Austral e documenta com base em fontes portuguesas os expedientes de segurança e militar entre autoridades portuguesas, sul-africanas e rodesianas. Tem como objetos dois processos: o "Exercício Alcora/Ameaça aos Países Alcora (factores)" e o "processo COLT". A pesquisa destes documentos foi feita em arquivos portugueses, nomeadamente no Arquivo Nacional da Torre do Tombo (ANTT) e no Arquivo Histórico Militar (AHM) no período entre Março e Maio de 2015.

The development of the ethanol agro-industry generated complex relationships within Brazilian society, an understanding of which requires analyses from a political, economic, anthropological and especially historical perspective. ProAlcool (National Ethanol Programme) induced changes in labour relationships and rural migration, while reinforcing technological development and economic and political capacities. It is important to mention, moreover, that the cultivation of sugarcane is closely related to the formation of the Brazilian economy and society since colonial times (i.e. since the beginning of the sixteenth century), having been the first economic activity developed by the Portuguese colonists.
