The growing significance of companies that conduct international business at or near their funding has been critically challenging previous incremental models of international expansion. This thesis aims to cross-compare, by means of a multiple-case study, eight Portuguese start-ups among themselves and with the theoretical concept of born global firms versus traditional ones. This work project finds that: (1) active entrepreneurs with global vision from inception are essential for the implementation of international strategies; (2) only formal network plays a key role for successful internationalization and (3) inimitable sources of value creation, niche-focused strategies and unique intangible assets are also crucial.

Academics are often ranked on citation counts’, which is considered an adequate proxy for author's quality and reputation. This paper seeks to find what is behind a cited academic / a cited article. We constructed a rich dataset from Portuguese affiliated economists and use zero inflated negative binomial model. This procedure is appropriate for count outcomes, correcting for overdispersion and excess zeros. We also use a fixed effect poisson model to accomodate authors' unobserved heterogeneity. We analyze results in detail comparing with existing literature and making some theoretical considerations around.

vThis research investigated Portuguese Hospitals’ Corporate Social Responsibility reporting practices, by analyzing Hospitals’ Annual Reports and websites. The main hospital stakeholders were presented and activities pertaining to each group included. Overall, it appears that there is a lack of strategic CSR reporting on both private and public hospitals. Hospital managers should include stakeholders in their CSR strategy and aim it at shared value creation. Hospitals need to build a stronger relationship with the community and reformulate CSR reporting practices to ensure that the reporting is timely, complete and relevant and is easily accessible by interested parties.

Cities develop according to different patterns, undergoing population growth during some periods and decline (shrinkage) during others. Theories attempting to understand these behaviours include: 1) shrinkage is a natural process in the life cycle of a city, alternating with periods of growth, or 2) shrinkage is an extreme event that places cities into a continuous decline process with no return to population growth. We use retrospective data over a period of 130 years to study 25 Portuguese cities currently facing population decline, and show that both theories coexist in time and space. Five types of shrinking city are revealed: “Persistent Early Shrinkage” due to exodus fromthe rural periphery, “Metropolitan Shrinkage” due to the challenges of urban sprawl, “Recent Shrinkage” in de-industrialisation hotspots, “Cyclic Shrinkage” occurring in political transformation cores, and “Mild Shrinkage” due to life-style disamenity. As diversity of city population trajectories appears to be the norm in both Portugal and other Western European countries, the incorporation of this range into the management of urban transitions is recommended in order to reinforce city resilience.

The Strait of Melaka is the longest strait in the world, stretching for about 800 km from the northern tip of Sumatra to Singapore. It exhibits a dual character like no other, being simultaneously a privileged linking passage of two seas and two knots of human civilization – India and China – and a »bottleneck« that constrains the maritime connections between them. Today, the latter aspect is globally dominant. The strait is considered and analysed mostly as an obstacle rather than a linking point: how to reach China from the West or elsewhere is no longer an issue, but securing the vital flows that pass into the strait on a daily basis undoubtedly is. Accidents, natural catastrophes, political local crises or terrorist attacks are permanent dangers that could cut this umbilical cord of world trade and jeopardize a particularly sensitive and vulnerable area; piracy and pollution are the most common local threats and vulnerabilities.

The management of terrorism presents an added importance because of the ignorance and uncertainty that this threat to peace launches in societies. From the globalization process has resulted a capacity of mobility and communication which allowed the spread of terrorism globally and hence the ability to be in the international agenda. Thus it became necessary a synergy between the main international organizations and states, in the common interest of managing terrorism to acceptable levels. This thesis aims to assess how much space is reserved for intelligence on combating terrorism. To this end, it carried out a literature review related to intelligence, security and terrorism, such as legislation and official documents, national and international. These allowed realize the strategies for combating terrorism of major international organizations and the Portuguese, the institutions that are in charge of fighting terrorism and related crimes, highlighting the intelligence institutions within the European Union and Portugal. Intelligence should enter on this panel by the need to meet the threat and its contours. On the one hand lies to understand the framework which establishes terrorism, tracing relevant scenarios to reduce uncertainty in decision-making and, on the other hand, also be responsible for disseminating information to other stakeholders on security, allowing its commands to use the means efficiently.

RESUMO - Introdução: A transição para a reforma é um acontecimento que pode acarretar alterações suscetíveis de afetar o estado de saúde. Vários estudos têm investigado os efeitos da reforma no estado de saúde, embora poucos o tenham investigado, especificamente, nas doenças crónicas. As recentes políticas de aumento da idade de reforma, assim como a ausência de consenso sobre os efeitos da reforma na saúde, atribuem-lhe ainda maior importância. Constituem objetivos do presente estudo quantificar a associação entre a Passagem à situação de reforma (e idade de reforma) e a frequência de cada uma das principais doenças crónicas, no sentido dos efeitos da reforma nestes indicadores de saúde (doença respiratória crónica, diabetes, doença cardiovascular, AVC, depressão e cancro). Material e Métodos: Desenvolveu-se um estudo transversal, no qual foram analisados os dados provenientes das amostras representativas da população portuguesa SHARE 2011 e ECOS 2013. As associações foram quantificadas através do cálculo do Odds ratio por Regressão Logística Binária com avaliação do confundimento e modificação de efeito. As variáveis de doença crónica foram medidas por auto-reporte. Foram considerados os reformados que se encontrassem em processo de reforma (ou seja, reformados há 5 anos ou menos) e que não se tivessem reformado por doença. Resultados: A reforma não se encontrou significativamente associada a nenhuma das doenças crónicas consideradas, excetuando-se: i) o cancro (na amostra ECOS), para o qual foi fator protetor; ii) e a doença cardiovascular (na amostra SHARE), para a qual teve um efeito prejudicial, mas apenas em não hipertensos. A reforma em idade antecipada pareceu encontrar-se associada a um pior estado de saúde, relativamente à reforma em idade legal (ou após). Tal observou-se no Cancro (nas amostras ECOS e SHARE), na Diabetes (na amostra SHARE), e no AVC em pessoas sem Doença Cardiovascular (na amostra SHARE). Pelo contrário, em pessoas com Doença Cardiovascular a reforma antecipada pareceu constituir um fator protetor. Discussão e conclusões: As diferenças observadas nos resultados entre amostras poderão, entre outros, atribuir-se às diferentes populações em estudo, dimensões amostrais e desenhos de amostragem. Os resultados obtidos não são muito diferentes dos que têm sido descritos na bibliografia, ainda que haja um número reduzido de estudos sobre esta matéria. Indicam que, eventualmente, as recentes alterações de aumento da idade de reforma poderão expandir o grupo de pessoas que se reformam antecipadamente, podendo resultar, eventualmente, num aumento da prevalência de doenças crónicas na população portuguesa. Os mecanismos através dos quais a reforma poderá influenciar a ocorrência de doenças crónicas permanecem por explicar, embora os seus principais fatores de risco pareçam representar importantes modificadores de efeito.

Portugal implemented a large number of structural reforms in the recent years, which are expected to enhance the allocation of resources in the economy, namely from the non-tradable to tradable sector. We argue that the methodology to identify the tradable sector used by some international institutions is outdated and may hamper an accurate assessment of the progress achieved so far. Based on an enhanced methodology to identify the tradable sector, we are able to provide a more accurate, clearer picture of the recent structural developments of the Portuguese economy.

This Work Project analyzes the evolution of the Portuguese personal income tax system’s progressivity over the period of 2005 through 2013. It presents the first computation of cardinal progressivity measures using administrative tax data for Portugal. We compute several progressivity indices and find that progressivity has had very modest variations from 2005 to 2012, whilst from 2012 to 2013 there has been a relatively stronger decrease, excluding the impact of the income tax surcharge of the years 2012 and 2013. When this latter is included, progressivity of 2012 and 2013 decreases considerably. Analyzing the effective average tax rates of the top income percentiles in the income scale, we find that these rates have increased over the period 2010–2013, suggesting that an analysis of effective tax rates is insufficient to assess progressivity in the whole tax scheme.

The report addresses the question of what are the preferences of broadband consumers on the Portuguese telecommunication market. A triple play bundle is being investigated. The discrete choice analysis, adopted in the study, base on 110 responses, mainly from NOVA students. The data for the analysis was collected via manually designed on-line survey. The results show that the price attribute is relatively the most important one while the television attribute is being overlooked in the decision making process. Main effects examined in the research are robust. In addition, "extras" components are being tested in terms of users' preferences.

RESUMO - A obesidade constitui um importante problema de saúde pública com consequências económicas de grande dimensão. Os obesos têm um risco acrescido de contrair doenças e de sofrer morte prematura devido a problemas como a diabetes, hipertensão arterial, AVC, insuficiência cardíaca e algumas neoplasias malignas. O presente estudo tem como objectivo estimar o custo económico indirecto (valor da produção perdida) associado à obesidade em Portugal no ano de 2002. O estudo adopta uma abordagem tipo custos da doença baseada na prevalência. Os dados são retirados do Inquérito Nacional de Saúde e estatísticas de rotina publicadas pelo INE e por outros organismos oficiais. Consideram-se como obesas pessoas com índice de massa corporal (IMC) ≥ 30 kg/m2 e estabelecem-se como limites etários para participação em actividades económicas produtivas as idades compreendidas entre os 15 e os 64 anos. A estratégia de imputação de custos ao factor de risco obesidade caracteriza- se por estimar, para a população portuguesa, as proporções de doença e morte prematura atribuíveis à obesidade e em multiplicar as estimativas populacionais encontradas pelo valor da produtividade económica potencial das pessoas afectadas. O custo indirecto total da obesidade em Portugal no ano de 2002 foi estimado em 199,8 milhões de euros. A mortalidade contribuiu com 58,4% deste valor (117 milhões de euros) e a morbilidade com 41,6% (83 milhões de euros). Os custos da morbilidade advêm de mais de 1,6 milhões de dias de incapacidade anuais, principalmente por faltas ao trabalho associadas a doenças do sistema circulatório e diabetes tipo II. Os custos da mortalidade são o resultado de 18 733 potenciais anos de vida activa perdidos, numa razão de 3 mortes masculinas por cada morte feminina. Os resultados indicam que a obesidade acarreta consideráveis perdas económicas para o país. Comparando os resultados com um estudo complementar que calculou os custos directos (em cuidados de saúde) da obesidade, verifica-se que a componente indirecta representa 40,2% do total dos custos da obesidade. A implementação de estratégias que prevenissem ou reduzissem a incidência e prevalência de obesidade em Portugal poderia gerar ganhos de produtividade elevados. Para conhecer a dimensão destes ganhos é necessária mais investigação sobre os benefícios clínicos e relação custo-efectividade de estratégias para a redução da obesidade.

ABSTRACT: Objectives: This study aimed to confirm whether 15 single nucleotide polymorphisms (SNPs) of selected genes are also associated with susceptibility for Juvenile idiopathic Arthritis (JIA) in thePortuguese population. Methods: Our study was conducted on Reuma.pt, the Rheumatic Diseases Portuguese Register, which includes patients with JIA receiving biological therapies and synthetic Disease Modifying Anti Rheumatic Drugs (DMARDs) since June 2001. Fifteen SNPs were investigated using Taqman® SNP genotyping assays in 291 Portuguese patients with JIA and 300 ethnically matched healthy controls. Results: Prior to Bonferroni correction for multiple testing, significant genotype association between one SNP and overall group of JIA was observed (PTPN22 rs2476601). In subgroup analysis, associations between six SNPs and the subgroup of patients with rheumatoid factor (RF)-positive Polyarticular (PTPN2 rs7234029), Extended oligoarticular (PTPN22 rs2476601), Systemic (PTPRC rs10919563, ANGPT1 rs7151781 and TNF rs361525) and Psoriatic JIA (IL2RA/CD25 rs2104286) were found. After Bonferroni correction for multiple testing, 3 genotype associations remained significant in the subgroup of patients with RF-positive polyarticular JIA (PTPN2 rs7234029 [corrected P 0.026]), extended oligoarticular (PTPN22 rs2476601 [corrected P 0.026]) and systemic JIA (ANGPT1 rs7151781 [corrected P 0.039]). Conclusion: Our results provide additional evidence for an association between polymorphisms in genes PTPN2, PTPN22 and ANGPT1 and the risk of RF-positive polyarticular, extended oligoarticular and systemic JIA, respectively, in a Portuguese population.
