A variabilidade no consumo de recursos nos traumatismos crânio-encefálicos

RESUMO - Portugal atravessa um contexto socioeconómico conturbado onde se têm imposto várias reformas, nomeadamente ao nível da Saúde. Atualmente, o financiamento do internamento hospitalar é feito por grupos de diagnóstico homogéneo com base num sistema prospetivo, reunindo os episódios em grupos clinicamente coerentes e homogéneos, de acordo com o consumo de recursos necessário para o seu tratamento, tendo em conta as suas características clínicas. Apesar do objetivo deste sistema de classificação de doentes, é aceite que existe variabilidade no consumo de recursos entre episódios semelhantes, sendo que a mesma variabilidade pode representar uma diferença significativa nos custos de tratamento. Os Traumatismos Cranio-encefálicos são considerados um problema de saúde pública, pelo que os episódios selecionados para este estudo tiveram por base os diagnósticos mais comuns relacionados com esta problemática. Procurou-se estudar a relação entre o consumo esperado e o observado bem como, a forma em que esta relação é influenciada por diferentes variáveis. Para verificar a existência de variabilidade no consumo de recursos, bem como as variáveis mais influentes, foi utilizada a regressão linear e constatou-se que variáveis como a idade, o destino pós-alta e o distrito têm poder explicativo sobre esta relação. Verificou-se igualmente que na sua generalidade as instituições hospitalares são eficientes na prestação de cuidados. Compreender a variabilidade do consumo de recursos e as suas implicações no financiamento poderá suscitar a dúvida se a utilização de GDH será o mais adequado à realidade portuguesa, de forma a ajustar as políticas de saúde, mantendo a eficiência e a qualidade dos cuidados.

A Constructivist perspective on EU'S democracy promotion in Turkey

The European Union, as a regional actor and an example of stability and well-being, has embraced a set of principles it has stood for and which constitute its own identity. The diffusion of these values among third countries is one of the objectives of EU’s External Policy. Democracy can be found among the principles that are sought to be exported through comprehensive and complex strategies within different frameworks, such as neighbourhood relations, trade partnerships and the accession process. Focusing on the latter, candidates are object of an intensive process of Europeanisation that operates through different mechanisms like socialisation and conditionality. Turkey, on the other side, has decided to apply for full membership several decades ago and, ever since, it has been pressured to Europeanise, which includes improving its unstable democracy. This case, however, is different from all other previous enlargements; for its special socio-cultural and civilisational features, Turkey constitutes a more complex novelty for the European Union. Therefore, this thesis aims to study the influence of the European Union on the democratisation process of Turkey, focusing on the period ranging between 1999, the year the European Council recognised Turkey’s candidacy status, and 2009 that marks the 10-year period of that condition. It is the intention of this project to assess the impact of the European Union at that level through the study of the democratic evolution of the country and its co-relation with other variables related to the presence or pressure of the EU. As this is a challenging objective, it will require a deep reflection upon central concepts like democracy and democratic consolidation, and a diversified use of methodological techniques, such as statistical analysis and mathematical co-relations, historical analysis, literature review and in-depth interviews. This study will privilege a Constructivist approach, emphasising the social construction of reality and the role of the ideational aspects – identity, perceptions and the broader socio-cultural dimension – in Turkey-EU relations.

Thermo-hydro-mechanical analysis of CO2 injection into deep aquifers

One of the biggest challenges for humanity is global warming and consequently, climate changes. Even though there has been increasing public awareness and investments from numerous countries concerning renewable energies, fossil fuels are and will continue to be in the near future, the main source of energy. Carbon capture and storage (CCS) is believed to be a serious measure to mitigate CO2 concentration. CCS briefly consists of capturing CO2 from the atmosphere or stationary emission sources and transporting and storing it via mineral carbonation, in oceans or geological media. The latter is referred to as carbon capture and geological storage (CCGS) and is considered to be the most promising of all solutions. Generally it consists of a storage (e.g. depleted oil reservoirs and deep saline aquifers) and sealing (commonly termed caprock in the oil industry) formations. The present study concerns the injection of CO2 into deep aquifers and regardless injection conditions, temperature gradients between carbon dioxide and the storage formation are likely to occur. Should the CO2 temperature be lower than the storage formation, a contractive behaviour of the reservoir and caprock is expected. The latter can result in the opening of new paths or re-opening of fractures, favouring leakage and compromising the CCGS project. During CO2 injection, coupled thermo-hydro-mechanical phenomena occur, which due to their complexity, hamper the assessment of each relative influence. For this purpose, several analyses were carried out in order to evaluate their influences but focusing on the thermal contractive behaviour. It was finally concluded that depending on mechanical and thermal properties of the pair aquifer-seal, the sealing caprock can undergo significant decreases in effective stress.

Achieving better service level results, through improvements in procedures

This project aims to prepare Worten Empresas (WE) fulfilling the increasing market demand through process changings, focusing on the Portuguese market, particularly on internal B2B clients1. Several methods were used to measure the current service level provided - process mapping, resources assessment, benchmark and a survey. The results were then used to compare against service level actually desired by WE’s customer, and then to identify the performance gaps in response times and quality of the follow-up during the sales process. To bridge the identified gaps, both a set of recommendations and an implementation plan were suggested to improve and monitor customer experience. This study concluded that it is possible to fulfill the increasing level of demand and at the same time improve customer satisfaction by implementing changes at the operations level.
