- Changing intention in 35 minutes : a brief TPB-informed online intervention to increase parental mediation of influencer marketingPublication . Rohde, Paul; Encarnação, Fátima Patrícia Nunes daOnline marketing to humans in their childhood, adolescent and early adulthood is an increasingly important research topic because it can on a larger scale than previously possible with traditional marketing lead to undesirable outcomes (e.g., obesity) and target more ethical grey zones between questionable, unfair and deceptive marketing to achieve its goals (Buijzen & Valkenburg, 2005; De Pauw et al., 2019). In particular, social media influencer content and embedded marketing might have a large effect (Folkvord et al., 2019). Promising solutions to the problems are interventions that increase the parental intentions to engage in behaviors that increase marketing-related knowledge and the skills of children before middle adulthood (De Pauw et al., 2019; Isaac & Grayson, 2019; Jung & Heo, 2019; Youn & Shin, 2019). Compared to school-based interventions, parents have more opportunities and time to influence the media diet directly and educate them with higher frequency and higher context-specificity by daily discussing the marketing their children actually engage with (Chen & Shi, 2019; Lin et al., 2019; Nelson et al., 2017). Consequently, the thesis purpose was to advance the knowledge of interventions that target parental intentions to engage in marketing-literacy-relevant behaviors. To this end, the study combined a conceptual and theoretical framework based on the theory of planned behavior (TPB) and broader intervention science concepts and an advanced experimental design (i.e., a randomized controlled online experiment composed of six intervention and one control). Numerous contributions are made. First, relatively brief (35 minutes) TBP-based online interventions can have a significant effect on parental intentions to engage in the discussion of influencer marketing. Second, the combined framework was highly valuable to inform an intervention design that produces effects of practical and theoretical importance. Third, the parsimonious TPB-based model is also appropriate for the context of parental mediation of influencer marketing because the three-based constructs were significant positive predictors of parental intentions. Lastly, parental attitudes are most susceptible to change and considerably predict intentions. Therefore, research efforts should focus on the study of parental attitudes and practical efforts should focus on targeting parental attitudes until marketing and influencer marketing become mainstream topics in the parental discourse.
- Planeamento de sucessões transnacionais no direito europeu : a relevância da autonomia da vontade na escolha da lei que regerá a sucessão e suas consequências no planeamento de sucessões transnacionaisPublication . Figueiredo, Ana Luiza Canuto de; Sousa, António Frada deO Regulamento Europeu das Sucessões conferiu enorme relevância à autonomia da vontade do autor de sucessão, o que garantiu não só maior segurança jurídica na determinação da lei aplicável a sucessões plurilocalizadas como também a possibilidade de o autor do planeamento optar pela lei que melhor se adeque às suas pretensões. Por meio de uma revisão doutrinária e jurisprudencial, o presente trabalho analisa a importância e os eventuais limites impostos à liberdade de escolha do autor da sucessão. Examina-se, também, o impacto da escolha da lei para fins de planeamento sucessório em um contexto de direito comparado. A partir da investigação, concluiu-se que embora a autonomia da vontade e a possibilidade de escolha da lei sejam elementos essenciais para a realização do planeamento de sucessões transnacionais, não são os únicos componentes a influenciar na eficácia do planeamento. A autonomia da vontade do autor pode ser afastada em função de determinadas limitações plasmadas no Regulamento. Tais limitações podem causar grande insegurança jurídica na realização de planeamentos sucessórios, colocando em risco sua eficácia em sede de processo sucessório.
- Responsabilidade dos administradores na insolvência culposa : obrigação de indemnizar interpretação da al. e) do n.º 2 do art. 189.° do CIRE : uma análise jurisprudencialPublication . França, Daniela Patrícia Silveira; Campos, Isabel MenéresA presente dissertação versa sobre a responsabilidade civil por insolvência culposa, mais concretamente sobre o efeito jurídico previsto na al. e) do n.º 2 do art. 189.º do CIRE: a obrigação de indemnizar. Introduzida pela Lei n.º 16/2012, de 20 de Abril, a al. e) do n.º 2 veio dar cumprimento à imperiosa necessidade de reforçar a tutela dos credores sociais. Ainda que revestido de elevada importância a redação dada a este regime é pouco clara, tendo dado, por isso, origem a diversas problemáticas. Uma vez confrontadas com tais problemáticas, doutrina e jurisprudência têm iniciado intensas discussões, a propósito do teor e alcance a dar a este efeito. Em face de tais quezílias, nesta exposição lograremos por proceder ao estudo do regime da obrigação de indemnizar onde explorando as suas vicissitudes e pontos de indefinição, tentaremos darlhe um ponto de harmonia e sentido útil.
- Inclusion of blood hydrolysates in European seabass (D. labrax) diets: impact on nutrient retention and fish resistance to T. maritimum infectionPublication . Resende, Daniela; Costas, Benjamin; Sá, Tiago; Golfetto, Umberto; Machado, Marina; Pereira, Miguel; Pereira, Carlos; Marques, Bianca; Pereira, Ricardo; Pintado, Manuela; Valente, Luisa M. P.Bioactive peptides are small amino acid chains with interesting properties (beyond their nutritional value), including antioxidant, mineral-binding, immunomodulatory or antimicrobial activities [1]. In this study, we hypothesised that including blood hydrolysates (BH) in aquafeeds could promote fish robustness, increase the economic value of animal blood and minimize waste, contributing to a circular economy. Additionally, BH with antimicrobial properties may address the T. maritimum infections that occur in aquaculture farms, with high impact on fish health, well-being and aquaculture production. Three fractions of swine BH obtained by autohydrolysis (AH) or enzymatically were selected. AH was oven dried. The BH obtained enzymatically were further submitted to a micro- (MF) and nanofiltration (NF) and freeze-dried. Dried hydrolysates were then included in five isolipidic and isoproteic diets for European seabass: a fishmeal (FM) based diet (positive control, PC), a commercial-based diet where 50% of FM was replaced by vegetable proteins (negative control, NC) and three diets where 3% of each BH was added to the NC. Diets were assigned to triplicate groups of 71 juveniles (initial weight 12.3±1.4 g), fed three times daily until apparent satiation in a recirculating saltwater system. Growth, nutrient utilisation and whole-body composition were evaluated after 12 weeks. At the end of the trial, ten fish per tank were infected with Tenacibaculum maritimum (3.5×105 cfu/L), in a two-hour water bath, and mortality was assessed for 8 days. Fish fed PC had the highest final weight, followed by NC and NF. The NC had a significantly higher weight than the MF and AH groups. Specific growth rate (SGR) and feed conversion ratio (FCR) of fish fed NF showed no significant differences from those fed PC and NC. Fish fed AH also displayed similar SGR to those fed NF and NC, but differed significantly from the MF. Despite no significant differences among treatments regarding final body composition, lipid and energy retention and gain were lowest in fish fed MF, which also had the lowest condition factor. Protein retention was unaffected by dietary treatments. Regarding the infectious challenge, NF had the lowest mortality rate that differed significantly from the NC and MF groups. Mortality for fish fed AH and PC did not differ from NF. MF showed the highest mortality. Overall, results indicate that dietary supplementation with NF clearly improves the resistance of European seabass to T. maritimum without affecting growth rate and can hence become a valuable ingredient for this species.
