Hotel industry: An answer to the emerging trends on the global demand side of tourism

This dissertation studies essentially how Millennials are changing the hotel industry, in the sense that new trends are emerging with this generation and hotels need to respond accordingly, in order to survive within their competitive industry. Emphasis is also given to Asian travellers, as the enlargement of these countries’ middle class populations is predicted, therefore making Asian travellers a valuable target for the hotel industry. To successfully target this segment, hoteliers need also to consider the cultural differences and aspirations that come together with the Asian travellers, and appropriately adapt their offer to them. I will then redirect this study to the city of Lisbon, the Portuguese capital, to analyse if Lisbon’s four and five-star hotel managers are aware of the new market trends, and to understand how they are changing their hotels in order to make them more attractive to Millennials and Asian travellers. Using a sample of 12 hotels (four and five-stars ratings), I have concluded that, although there is a notable undergoing process of adaptation to these guests, there is a long way ahead in order for Lisbon’s hotels to entirely please and retain millennial guests.

An agent-based simulator to estimate domestic energy use

Throughout recent years, there has been an increase in the population size, as well as a fast economic growth, which has led to an increase of the energy demand that comes mainly from fossil fuels. In order to reduce the ecological footprint, governments have implemented sustainable measures and it is expected that by 2035 the energy produced from renewable energy sources, such as wind and solar would be responsible for one-third of the energy produced globally. However, since the energy produced from renewable sources is governed by the availability of the respective primary energy source there is often a mismatch between production and demand, which could be solved by adding flexibility on the demand side through demand response (DR). DR programs influence the end-user electricity usage by changing its cost along the time. Under this scenario the user needs to estimate the energy demand and on-site production in advance to plan its energy demand according to the energy price. This work focuses on the development of an agent-based electrical simulator, capable of: (a) estimating the energy demand and on-site generation with a 1-min time resolution for a 24-h period, (b) calculating the energy price for a given scenario, (c) making suggestions on how to maximize the usage of renewable energy produced on-site and to lower the electricity costs by rescheduling the use of certain appliances. The results show that this simulator allows reducing the energy bill by 11% and almost doubling the use of renewable energy produced on-site.

Caracterização da carga da doença arterial periférica dos membros inferiores : contributos para um melhor conhecimento do peso desta doença no internamento hospitalar

RESUMO - A doença arterial periférica (DAP) apresenta uma carga de doença significativa, afetando cerca de 3 a 10% da população em geral e 15 a 20% dos indivíduos com idade superior a 70 anos. A sua prevalência em Portugal foi estimada em cerca de 5,9% no continente; 6,6% na Região Autónoma dos Açores (RAA) e 3,8% na Região Autónoma da Madeira (RAM). Para além da importante carga de doença, quer em termos epidemiológicos, quer económicos, a DAP confere aos seus portadores um risco cardiovascular agravado, sendo que os mesmos apresentam cerca do triplo do risco de mortalidade e de eventos cardiovasculares quando comparados com indivíduos sem DAP. Tratou-se de um estudo observacional, transversal e descritivo tendo como base duas populações de estudo. A primeira é referente aos hospitais do Serviço Nacional de Saúde (SNS) com a valência de cirurgia vascular e a segunda à população portuguesa com episódios de internamento por diagnóstico de DAP dos membros inferiores (MI) nos anos de 2013 e 2014 na totalidade dos hospitais do SNS. Através da análise dos resultados do questionário procedeu-se à descrição de algumas das características dos serviços e unidades de cirurgia vascular de sete hospitais do SNS; através da análise da base de dados dos GDH para os anos de 2013 e 2014 procedeu-se à caracterização do peso do internamento por DAP dos membros inferiores a nível nacional no mesmo período. A DAP tem uma carga significativa e atendendo aos seus fatores de risco e história natural da doença, apresenta uma tendência crescente durante os próximos anos, representando por isso um enorme desafio para os sistemas de saúde. São, no entanto, necessários estudos mais aprofundados sobre o tema que permitam conhecer melhor o peso desta patologia e, de forma global, melhorar o planeamento, tendo por base a caracterização quer do lado da procura (dados epidemiológicos e peso no internamento), quer da oferta (capacidade instalada).

Yacht charter in Portugal- developing a business model for a sailing charter company

Given the signals that Portugal can be a great destination for charter sailing, the purpose of this work is to disprove this. Thereby the model of Porter’s five forces has been used to analyze the Portuguese yacht charter market, whereas a SWOT analysis should give an overview and compare the Portuguese market with the well running charter market of Croatia. The research outcome on the supply side as well as on the demand side should then serve as a foundation for establishing a model of a sailing charter company in Portugal, explained with the aid of the Canvas model.
