Publicação Acesso AbertoNon-Specific Pleuritis after Medical Thoracoscopy: A Prospective Study2023-03-09 - Seixas, Eduarda; Ferreira, Pedro Gonçalo; Seixas, Carlos; Teixeira, Gilberto; Rodrigues, Bárbara; Seixas, CarlosMore than 50 causes of pleural effusion are known and, although the majority are benign (85%), both malignant and unknown causes are common. [...] Publicação Acesso AbertoThe Intolerance of Uncertainty Scale (IUS): Translation and adaptation to European Portuguese2022-10 - Botelho, Catarina; Barbosa, Fernando; Campos, Carlos; Fernandes, Carina; Ferreira-Santos, Fernando; Marques-Teixeira, João; Pasion, Rita; Seixas, Carlos; Paiva, Tiago O.; Seixas, CarlosIntolerance of uncertainty is defined as the individual’s excessive propensity to find unacceptable the probability of a negative event occurring (Dugas et al., 2001b; Buhr & Dugas, 2002). This propensity is brought up bya set of negative beliefs about uncertainty and its consequences (e.g., uncertainty is unacceptable and should be avoided, and/or it leads to the inability to act;Buhr & Dugas, 2002; Freeston et al., 1994; Sexton & Dugas, 2009). [...] Publicação Acesso AbertoUncertainty deconstructed: conceptual analysis and state-of-the-art review of the ERP correlates of risk and ambiguity in decision-making2023-05-12 - Botelho, Catarina; Fernandes, Carina; Campos, Carlos; Seixas, Carlos; Pasion, Rita; Garcez, Helena; Ferreira-Santos, Fernando; Barbosa, Fernando; Maques-Teixeira, João; Paiva, Tiago O.; Seixas, CarlosRisk and uncertainty are central concepts of decision neuroscience. However, a comprehensive review of the literature shows that most studies define risk and uncertainty in an unclear fashion or use both terms interchangeably, which hinders the integration of the existing findings. We suggest uncertainty as an umbrella term that comprises scenarios characterized by outcome variance where relevant information about the type and likelihood of outcomes may be somewhat unavailable (ambiguity) and scenarios where the likelihood of outcomes is known (risk). These conceptual issues are problematic for studies on the temporal neurodynamics of decision-making under risk and ambiguity, because they lead to heterogeneity in task design and the interpretation of the results. To assess this problem, we conducted a state-of-the-art review of ERP studies on risk and ambiguity in decision-making. By employing the above definitions to 16 reviewed studies, our results suggest that: (a) research has focused more on risk than ambiguity processing; (b) studies assessing decision-making under risk often implemented descriptive-based paradigms, whereas studies assessing ambiguity processing equally implemented descriptive- and experience-based tasks; (c) descriptive-based studies link risk processing to increased frontal negativities (e.g., N2, N400) and both risk and ambiguity to reduced parietal positivities (e.g., P2, P3); (d) experience-based studies link risk to increased P3 amplitudes and ambiguity to increased frontal negativities and the LPC component; (e) both risk and ambiguity processing seem to be related with cognitive control, conflict monitoring, and increased cognitive demand; (f) further research and improved tasks are needed to dissociate risk and ambiguity processing. Publicação Acesso AbertoA Domain-specific Risk-attitude Scale (DRaS): Translation and adaptation to European Portuguese2022-10 - Botelho, Catarina; Barbosa, Fernando; Campos, Carlos; Fernandes, Carina; Ferreira-Santos, Fernando; Marques-Teixeira, João; Pasion, Rita; Seixas, Carlos; Seixas, CarlosRisk attitude, as conceptualized in the classic economic approach, reflects the individual’s sensitivity to disparities in outcomes (i.e., payoffs) variance (Yechiam & Ert, 2011). Brachinger and Weber (1997) further propose that risk attitude depends on the tendency to prefer/avoid risk over certainty. Thus, the degree of risk acceptance underlies risk attitudes. Likewise, Risk-Return models (Weber & Milliman, 1997; Weber, 2010) theorize that risk attitude reflects the preference for risky options. This risk preference, in turn, depends on the trade-off between an option’s expected benefit (subjective expected value) and its riskiness (an idiosyncratic variable that depends on the context and content of the decision). Publicação Acesso AbertoPromoting the transition to a Circular Economy: A study about behaviour, attitudes and knowledge by university students in Portugal2023-12-29 - Alves, Márcia N.; Seixas, Carlos; Castro, Alberto; Leitão, Alexandra; Seixas, CarlosYounger and highly skilled generations are one of the major driving forces of a successful transformation to a circular economy (CE); therefore, this paper intends to assess the prevalent behaviour, attitudes, and knowledge of the CE by university students. The study focuses specifically on Portuguese students. Some new conclusions were added to the existent literature. Our conclusions show that, although students engage in several types of CE behaviour and have positive attitudes, these mostly include actions such as reducing food waste, recycling practices, or purchasing energy-efficient products. Circular consumption habits like remanufactured products, second-hand purchases, the sharing economy, and product-as-a-service systems (PSSs) still need further implementation. However, we determine that the level of knowledge of the CE goes beyond the conventional recycling premise. Moreover, we have included an innovative part, based on a probit model, by studying how knowledge of the CE affects students’ behaviour and attitudes and conclude that it positively influences them. Other variables such as age, gender, and level of education are also found to influence actions and attitudes. As a result, this study can significantly improve the overview of the current situation and provide a starting point for measuring the effectiveness of future policies to be defined. Publicação Acesso RestritoThe Show Can Go On! The non-existent effect of corruption in Fandom (evidence from Portugal)2023-10-30 - Moriconi, Marcelo; Calca, Patrícia; Seixas, Carlos; Seixas, CarlosOne of the key premises of the official sports integrity narrative is that the perception of widespread of corruption in sports leads to a decline in people’s interest in sports and to the consequent cultural and financial collapse of the sector. With evidence gathered through a representative survey conducted in Portugal, this article proves this premise to be inaccurate. Despite football being commonly perceived as a corrupt industry, the interest of fans remains unalterable regardless of gender, ideology, political preference, age, or place of residence. This article holds relevance in the ongoing discussion about the implications of sports integrity policy-making processes as it shows that maintaining supporters’ level of engagement is not significantly impacted by concerns over integrity itself. The conclusion discusses the ethical implications that this situation generates and proposes a series of recommendations to enhance integrity and good sports governance. Publicação Acesso AbertoCircular Economy: Behaviours, attitudes and knowledge of university students in Portugal [comunicação oral]2023-07-20 - Alves, Márcia; Seixas, Carlos; Leitão, Alexandra; Seixas, CarlosThe goal of this paper is to assess behaviours, attitudes, and knowledge about circular economy (CE) by university students, since younger and highly skilled generations are one of the major driving forces of a successful CE transformation. The study focuses specifically on Portuguese students. Data collection from the target audience was made using an online questionnaire, and 377 answers were obtained. The results show that students engage several CE behaviours and have positive attitudes. However, these include mostly actions such as reducing food waste, recycling practices, or purchasing energy efficient products. Remanufactured products, second-hand purchases, sharing economy and product-as-a-service systems (PSSs) are circular consumption habits that still need further implementation. Results additionally indicate the level of knowledge tends to be satisfactory and goes beyond the conventional recycling premise. Based on a probit model, we also study the relation between behaviours, attitudes and knowledge and find knowledge positively influences several students’ behaviours and attitudes. Other variables influencing effective actions, and attitudes are also identified. Finally, policy implications are drawn.

[...] Publicação Acesso AbertoThe Show Must Go On! The Non-Existence of Corruption in Football [comunicação oral]2022-09-21 - Seixas, Carlos; Moriconi, Marcelo; Calça, Patrícia; Seixas, CarlosOne of the key premises of the official sports integrity narrative is that the perception of high levels of corruption lead to a general loss of interest in sport and to consequent cultural and financial collapse of the sector. With evidence gathered through a representative survey carried out in Portugal, this article empirically shows that this premise is inaccurate. While football is considered a corrupt industry, the interest of fans remains unalterable regardless of gender, ideology, political preference, age, or place of residence. This article is relevant to the discussion about the implications of sports integrity policy-making processes, since integrity itself does not seem to be an important issue with regards to maintaining the supporter’s level of engagement. The conclusion discusses the ethical implications that this situation generates and advances a series of recommendations to justify the improvements of the policies for integrity and good sports governance. Publicação Acesso AbertoEuropean integration and the presidentialization of political systems: an application to the portuguese case2023-04 - Seixas, Carlos; Antunes, Francisco; Costa, Manuel; Seixas, CarlosPoguntke and Webb (2005) formulated the theory of presidentialization, according to which the parliamentary and semi-presidential systems tended to approximate to presidential system of government in their practical aspect without, in most cases, noticeable changes in the formal aspects. The internationalization of policymaking is one of the main causes of this process, which is especially important in the case of member states of the European Union. This work focuses on studying the Portuguese case. Several authors have identified the increase in the powers of Prime Ministers and pointed out europeanization as one of the causes for this phenomenon. However, so far, no attempt has been made to validate these ideas through statistical analysis. This work analyses the impacts of europeanization on the ministerial selection in the Portuguese political system through an econometric model. It concludes that, the European integration has no contribution in the likelihood of an experience minister being appointed. However, the European integration has contributed to an increase in the likelihood of independent ministers being appointed, in relation to inside ministers, which is interpreted as evidence of the growth of the Prime Minister's powers in the Portuguese system of government. Thus, the present work allows for the conclusion that, in fact, europeanization has contributed to the presidentialization of the political system in Portugal.
