- Análise qualitativa e exploratória sobre os mitos da violação e estereótipos de género associados aos consumos sociais de álcool e de outras substâncias psicoativas, num grupo de jovens altutos/as (18-24 anos)Publication . Lopes, Ana Rita Gonçalves Antunes; Pires, Cristiana do ValeA violência sexual em ambientes de lazer noturno (ALN) e em contextos festivos é uma preocupação crescente, sendo perpetuada por assimetrias de género e normas hegemónicas que naturalizam comportamentos abusivos e perpetuam relações desiguais de poder. Esta investigação teve como objetivo explorar as perceções de jovens sobre o papel dessas substâncias na dinâmica de vitimização sexual, com um foco particular no álcool e outras substâncias, bem como nas normas culturais de género que moldam comportamentos e atitudes nesses ambientes. O estudo adotou uma abordagem qualitativa, utilizando grupos de discussão com jovens para explorar as suas perceções e experiências. Os resultados revelaram que tanto mulheres quanto homens percebem o álcool como um fator facilitador da vitimização, que amplifica a vulnerabilidade das vítimas e a agressividade dos agressores. As mulheres que participaram neste estudo reportaram adotar mais estratégias de proteção e “vigilância sexual” para prevenir a violência sexual, evidenciando as expectativas sociais que as responsabilizam pela sua própria segurança. Já os homens, embora reconhecendo o uso de substâncias em ALN, tendem a minimizar os impactos da violência sexual, especialmente em casos sem danos físicos visíveis. O estudo também evidenciou a normalização do consumo de álcool e a adulteração de bebidas como fatores que agravam a exposição ao risco. Este estudo reforça a necessidade de se implementarem campanhas de sensibilização mais inclusivas e estratégias de prevenção que desafiem os estereótipos de género, promovam o consentimento explícito e responsabilizem os agressores. A pesquisa sugere que é essencial a implementação de políticas públicas claras, educação contínua e medidas de proteção mais eficazes em ALN para reduzir a incidência de violência sexual e criar espaços mais seguros e equitativos para todos.

- Extending the shelf-life of live clams, Venerupis corrugata - important aspects of current packaging and advances in modified atmosphere packagingPublication . Goes, Cintia Borghetti; Teixeira, Susana; Mena, Cristina; Silva, Fátima; Cruz, Andreia; Basílio, Inês; Hogg, Maria Conceição; Sivertsvik, Morten; Teixeira, Paula; Poças, FátimaVenerupis corrugata (pullet carpet shell) is a premium native clam species in Portugal. This species is highly perishable, typically sold live within 3 or 4 days, posing a significant risk of loss. Therefore, efforts to extend its shelf-life are relevant. The impact of the storage temperature (3, 5, 8 and 12 °C) on clams in plastic net bags and the effect of modified atmosphere packaging (MAP) were investigated. The survival percentage and microbiological and chemical parameters were evaluated, as well as sensory characteristics. The survival percentage and sensory aspects results indicate that the longest time with 95% live clams was observed at 5 °C and 8 °C, but lower temperatures (3 and 5 °C) have lower death rates after the threshold. In the MAP tests, the clams were kept closed due to confinement in plastic trays applying a vacuum, before gas flushing that drew the lid film over the clams. However, a negative effect of CO2 was observed for clams, with lower survival when packaged in 30% CO2. The shelf-life increased by only 1–2 days under >70% O2 with no CO2. These results show that this species is very sensitive, and MAP is not commercially effective for this application.
- Establishing a new standard for the health sector in Europe : study of an acquisition by Ramsay Générale de Santé of Humana ABPublication . Roxo, Miguel Garcês Meira; Assunção, António Borges deHealthcare is central to the world as we know. As the world and population evolve, new challenges gain shape. This principle applies to the health sector as well, with ageing population, increasing chronic diseases and the rise of mental health. Therefore, this dissertation aims to study, as of December 31st 2023, how Ramsay Générale de Santé, a leading private comprehensive health French company can acquire Humana AB, a private Swedish welfare player. For that, Discounted Cash Flow and Trading and Transaction Multiples were used to obtain the value for both firms and then assess whether this acquisition would create value. The deal, projects that Ramsay would acquire Humana for c. € 621,19M, implying a premium of 75% over its share price of € 2,45 at December 29th 2023. This acquisition would rely on Ramsay using a mix of cash on hand and take over Humana´s existing debt, resulting in an approximated split of 35%/65%, respectively. The synergies from this transaction are mainly driven by Ramsay being able to offer an even more comprehensive care offering, achievement of economies of scale, Humana having better resources to offer a both more specialized and digital care, while Ramsay having a strong track record of integrating strategic investments. With the previous context, the deal would preliminarily result in synergies of € 190,2M, almost 3% of both firms combined without synergies. With the aforementioned financing mix, this deal would offer an average accretion of 25,7% to Ramsay.
- The role of nostalgic marketing in shaping hedonic consumption behaviour, and purchase intentionsPublication . Görlach, Clara Friederike; Braga, João NizaThis study investigates the influence of nostalgic marketing on hedonic consumption behavior and purchase intentions, with a specific focus on the iconic skincare brand Nivea. As a brand, deeply rooted in tradition and trust, Nivea serves as an ideal case for exploring how nostalgia driven marketing can enhance emotional resonance and consumer loyalty. A quantitative experimental design was employed, splitting participants into four groups to assess the interaction between nostalgic marketing and consumption type (hedonic vs. utilitarian). The study utilized a combination of structured surveys and statistical analyses to measure variables such as hedonic & utilitarian motivations, purchase intentions and willingness to pay a price premium, ensuring reliability and validity through structured methodologies. Findings reveal that nostalgic marketing enhances emotional engagement and hedonic product perceptions. However, it does not consistently translate into increased purchase intentions or willingness to pay a price premium. Notably, brand familiarity emerged as a critical factor in influencing consumer behavior. This study underscores the strategic potential and limitations of nostalgia in hedonic marketing within the skincare sector.
- The effectiveness of FoMO and scarcity marketing on impulsive buying tendenciesPublication . Rodrigues, Maria Leonor Ildefonso; Braga, João NizaFear of Missing Out (FoMO) and scarcity are psychological tools that influence consumer behaviour, mainly in current digital contexts, where urgency-driven marketing strategies are prevalent. This study explores the interplay between FoMO, scarcity, impulsive buying tendencies (IBT) and purchase likelihood, analysing IBT as a behavioural consequence of these emotional triggers. Using a sample of 143 participants, this research assesses how these factors influence decision-making processes. Four distinct stimuli with varying levels of FoMO and scarcity were developed to assess their impact on anxiety, urgency perceptions and impulsive behaviour. The findings indicate that while FoMO and scarcity increase anxiety and urgency, they do not directly increase the tendency for impulsive buying. Furthermore, these factors presented no significant direct effects on consumer impulsive behaviour, suggesting that their effect is context-dependent and depends on individual characteristics. These study challenged assumptions about the universal effects of FoMO and scarcity on impulsive purchases (Aggarwal et al., 2011; Good & Hyman, 2020). For businesses, these results highlight the importance of carefully implementing these cues, as excessive use may lead to customer reactance. Based on this study´s limitations, it is recommended for future research to explore cultural and psychological moderators in the relationship between FoMO, scarcity and consumer decision making.
- Nearshoring as a sourcing strategy for the German fashion industry : a forward-looking analysisPublication . Erthal, Marie-Luise; Rajsingh, PeterThis study examines the role of nearshoring in the German fashion industry and evaluates its potential as a dominant sourcing strategy. While nearshoring is increasingly discussed as an alternative to Offshoring, its actual impact remains debated. To assess this, a mixedmethods approach was applied, integrating expert interviews, literature analysis, and a scenario-based Cross-Impact Balance analysis to identify key influencing factors. The identified factors indicate that nearshoring is unlikely to see significant growth under current market conditions. While drivers such as regulatory developments, time to market, and sustainability goals create incentives, price-sensitive consumer preferences, operational constraints, and cost considerations limit its broad adoption. For the near future, companies are expected to maintain their current sourcing strategies that balance cost, risk, and demand. The scenario analysis further supports this conclusion. Most companies will continue to prioritize Global Sourcing due to cost efficiency, established supply chain structures, and logistical considerations. Only under specific conditions, such as stricter regulations, increased demand for quickly available sustainable products, and advancements in automation, does nearshoring gain strategic relevance. This study contributes to the academic discourse by integrating management theory, strategic procurement frameworks, and value chain perspectives. It provides a comprehensive assessment of nearshoring’s role in the German fashion industry, highlighting both its opportunities and limitations. By offering insights into key influencing factors and future developments, this research helps decision-makers assess the viability of nearshoring as part of a long-term procurement approach.
- Navigating industry evolution : the strategic challenges of Ferri AssicuraPublication . Ferri, Claudio; Guedes, NunoThis Dissertation examines the challenges faced by Ferri Assicura, an Italian family-owned insurance agency, as it navigates digital transformation and changing consumer behavior in an increasingly commoditized market. Traditionally built on face-to-face relationships, small agencies like Ferri Assicura now compete with digital-first Insurtech firms that prioritize low prices, flexibility, and on-demand coverage. The agency must balance modernization— required by the large insurer it depends on for its product portfolio—against limited resources and operational constraints, raising questions about its long-term competitiveness. Designed as a pedagogical tool for in-class discussion, this Case Study provides a foundation for students to analyze industry shifts, investigate the challenges faced by traditional agencies, and explore pathways for adaptation. Through a Literature Review of topics relevant to Ferri Assicura’s challenges and the analysis in the Teaching Note, the Thesis highlights trust as a crucial differentiator, allowing small agencies to position themselves as advisory experts rather than transactional intermediaries. A failed merger project further underscored difficulties in scaling operations and the need for structural adaptation. To remain competitive, Ferri Assicura must adopt a hybrid approach—leveraging digital visibility to attract younger consumers while reinforcing its value in complex, high-trust insurance segments. By developing a more structured organization, refining client engagement strategies, and expanding its service portfolio, Ferri Assicura will position itself for sustainable growth in a dynamic market.
- Authenticity-based consumer responses : do individualistic or group-affiliating messages in Instagram advertisements enhance gen Z's perception of personal authenticity?Publication . Geinez, Anita; Braga, João NizaThe growing interest in consumers perception of authenticity results from the fact that it does not only result in higher psychological wellbeing and health but also has established a crucial competitive advantage for brands aiming at building strong relationships. Especially members of Gen Z are characterised by their demand for authenticity.The present study explores how individualistic and group-affiliating advertisements on Instagram impact Gen Z's perceived personal authenticity and consumer responses. Utilizing a 2x2 between subjects design (social belonging priming: inclusion/exclusion advertisement message: individualistic/group-affiliating) with 123 participants, the research reveals a significant interaction. Socially excluded Gen Z members reported higher personal authenticity, expected pleasure, and purchase intention with group-affiliating advertisements, while socially included individuals benefited from individualistic messages. Group-affiliating advertisements also drove higher sharing intentions across both social belonging conditions. Importantly, perceived personal authenticity is positively correlated with purchase intention. Therefore, it lastly influences tangible business outcomes.
- Adoption of post-quantum cryptography in organizations : challenges and driversPublication . Zimmermann, Daniel; Rajsingh, Peter V.The emergence of quantum computing poses a significant threat to modern encryption standards, with the potential to render widely used cryptographic protocols obsolete. To mitigate this risk, organizations must transition to post-quantum cryptography (PQC), a process that requires technical, operational, and strategic adjustments. However, the pace and approach to adoption vary across industries and organizational size, influenced by both external pressures and internal capabilities. This study employs a mixed-methods approach, incorporating 14 expert interviews and survey responses from 37 cybersecurity professionals to examine the factors driving and inhibiting PQC adoption. The findings reveal that while regulatory mandates play a role, organizations are increasingly guided by risk exposure and reputational concerns. Key challenges include resource constraints, reliance on third-party vendors, and the complexity of cryptographic inventory assessments and legacy systems. Despite these challenges, the study found that PQC adoption will accelerate as risk awareness grows and implementation guidelines become available. It emphasizes the importance of a strategic, resilience-focused approach to cybersecurity, incorporating cryptographic agility, continuous assessments, and hybrid encryption solutions to navigate the evolving threat landscape.
