- Market exuberance in sovereign credit default swaps: assessing the EU regulatory framework and trading profit opportunitiesPublication . Oliveira, Maria Alberta; Santos, CarlosSovereign credit default swaps (SCDSs) have been at the core of the Euro Area (EA) debt crisis, particularly in its periphery. Both EU politicians and a wide range of EU academics have asked for tighter regulation of these over-thecounter (OTC) derivatives, following similar pressures to the ones that had resulted from the 2008 financial crisis for corporate reference entities. As such, the SCDSs regulatory framework experienced a number of changes from 2009 to 2014, in the EU. This paper provides a seminal assessment on whether these new rules have succeeded in preventing SCDSs exuberance episodes in the EU. Using daily data for 5 years maturity Greek SCDSs, comprising the period between the latest regulatory reform, in September 2014, and mid-March 2015, we find clear evidence of explosive behavior in SCDSs spreads, and even in upfront quotes. The authors take advantage of the new Phillips et al. (2015a, 2015b) test for multiple exuberance episodes, which had rarely been used in derivatives markets, and conduct an event study to conclude that Greek elections, in early 2015, and the associated turmoil has led to a surge in momentum trading, with significant potential returns for SCDSs buyers. The regulatory measures aiming at deleveraging these markets, standardizing contracts, and dissociating sovereign and banking risk, do not seem to have achieved their purposes, as the political and financial anxiety in Greece, starting in December 2014, has led to explosive behaviour episodes in the market for Greek SCDSs, of the type regulators had tried to avoid.

- Psicopatia no Feminino: Uma Breve Revisão da sua Avaliação e SubtiposPublication . Moreira, D.; Pinto, M.; Almeida, F.; Barros, S.; Barbosa, F.A psicopatia é um dos construtos mais amplamente estudados na literatura sobre estruturas de personalidade. O objetivo deste artigo é apresentar uma breve revisão da literatura da psicopatia nas mulheres focando algumas dificuldades relacionadas ao conceito, à avaliação, e aos subtipos. Os estudos indicam que a psicopatia nas mulheres tem sido um tema muito pouco estudado e que os estudos que existem utilizaram predominantemente amostras de reclusos homens para suportar a concetualização de subtipos de psicopatia em primários e secundários. Seria útil, também para a prática clínica, fazer estudos ao nível da etiologia, do comportamento, e do processamento emocional da psicopatia nas mulheres.

- Decisão de retirada, acolhimento e reunificação: A perspetiva dos estudantes portugueses das ciências sociais e humanas.Publication . Martins, Teresa; Carvalho, João M. S.; Delgado, PauloPerante contextos familiares de negligência ou maus-tratos, o Estado interfere para salvaguardar o desenvolvimento e o bem-estar da criança ou jovem em perigo. Este estudo propõe-se compreender as representações que 200 estudantes do Ensino Superior, das áreas das Ciências Sociais e Humanas, têm sobre o sistema de proteção. Conclui-se que os estudantes são mais favoráveis à retirada da criança ou jovem com preferência pela institucionalização face ao acolhimento familiar. Este facto é um sinal de alerta para a necessidade de uma formação inicial mais abrangente e integradora das várias respostas possíveis, para que se possa privilegiar, de facto, o superior interesse da criança.
- Inflammatory and Cardiometabolic Risk on Obesity: Role of Environmental XenoestrogensPublication . Teixeira, Diana; Pestana, Diogo; Santos, Cristina; Correia-Sá, Luísa; Marques, Cláudia; Norberto, Sónia; Meireles, Manuela; Faria, Ana; Silva, Ricardo; Faria, Gil; Sá, Carla; Freitas, Paula; Taveira-Gomes, António; Domingues, Valentina; Delerue-Matos, Cristina; Calhau, Conceição; Monteiro, RosárioSome chemicals used in consumer products or manufacturing (eg, plastics, pesticides) have estrogenic activities; these xenoestrogens (XEs) may affect immune responses and have recently emerged as a new risk factors for obesity and cardiovascular disease. However, the extent and impact on health of chronic exposure of the general population to XEs are still unknown.
- Designing an AHP methodology to prioritize critical elements for product innovation: an intellectual capital perspectivePublication . Costa, Ricardo Vergueiro; Ramos, Ana PaulaIntellectual capital has for the past decades been evidenced as an important source of competitive advantages and differentiation at the firm level. At the same time, innovation has become a critical factor for companies to ensure their sustainability and even their survival in a globalized business landscape. Having in mind these two crucial concepts for business success, this study intends to build on the relationships between intellectual capital and product innovation at the firm level. Specifically, we will design and test a model based on the Analytic Hierarchy Process, whose aim is to allow the prioritization of intellectual capital elements according to their relative importance for product innovation performance at the firm level. The main goal of this research is to build a diagnosis and action tool that helps business managers incorporate an intellectual capital perspective into their product innovation initiatives. This framework will help managers to better understand which intellectual capital elements are more critical to their product innovation efforts, and thereby systematize actions and clarify resource allocation priorities to improve their product innovation capabilities. In order to validate the practicability of this proposal, the methodology was empirically applied to a Portuguese innovative company .

- Social Responsibility, Corporate Citizenship Scale and Core Organizational Stakeholder Impact – A Case StudyPublication . Carvalho, João M. S.; Carvalho, NunoIn a scenario of globalization, social inequality, environmental degradation, and an increased demand from consumers and/or clients, companies had to rethink their behaviours, focusing on taking more socially responsible decisions. In this research, the main theme is Corporate Social Responsibility (CSR), which has been analysed in its origin, conceptual evolution, and the development of measure tools associated to this concept. The empirical study was carried out in a Portuguese information technology company, through the application of two measure instruments - Corporate Citizenship Core Scale and Core Organizational Stakeholder Impact - reaching out the conclusion that its employees perceive the legal dimension of social responsibility as the one that has more prominent features, as well as the existence of an insufficient positive impact on stakeholders, both internal and external. The use of these measure tools can help raise awareness among managers for the gaps in the way they relate to stakeholders, allowing adjustments in companies’ behaviour and strategic directions, leading to greater business success and a better social welfare.
