- Nursing technicians' perceptions about the use of play and playfulness in professional practicesPublication . Petrucelli, Gabriele; Wernet, Monika; Silveira, Aline Oliveira; Maia, Edmara Bazoni Soares; Almeida, Cristiane Leite de; Loureiro, Fernanda ManuelaObjective: To understand nursing technicians’ perceptions in a pediatric inpatient unit regarding the use of play and playfulness in their professional practices. Method: An exploratory study with a qualitative approach, supported by the Symbolic Interactionism theoretical framework, developed in a pediatric unit of a university hospital in the countryside of São Paulo. Data collection took place from March to December 2024, through semi-structured interviews, with 14 participants. Reflective thematic analysis supported data assessment. Results: The topics “Purposes of adopting play and playfulness” and “Determinants of adopting play and playfulness” revealed that nursing technicians link resources with the execution of technical procedures and formation of bonds. However, they highlighted a context that was not very supportive of this use and that led to the meaning that these resources were other professionals’ responsibility. Conclusion: The use of play and playfulness predominated for the execution of procedures, with a secondary, informal, voluntary and non-institutionalized place in nursing care for children.
- Condomínio, condóminos e arrendatárioPublication . Mouta, Natália Alexandra da Cruz Pinto; Afonso, Ana Isabel da CostaA presente tese analisa o regime jurídico da propriedade horizontal em Portugal, com especial enfoque no respeito do arrendatário pelas regras do condomínio, na realização de obras nas partes comuns e na possibilidade de arrendamento dessas mesmas áreas. A propriedade horizontal, enquanto forma de organização do imóvel, apresenta desafios significativos na gestão dos interesses dos condóminos, exigindo um equilíbrio entre os direitos individuais e a preservação do interesse coletivo. Num primeiro momento, procede-se à delimitação do conceito de constituição da propriedade horizontal, seguindo-se uma análise sobre o dever do arrendatário de respeito das regras estabelecidas pelo condomínio. No que concerne ao arrendamento de partes comuns, discute-se a legalidade e viabilidade desta prática, ponderando-se a necessidade de autorização por parte do condomínio, os direitos e deveres dos condóminos e as possíveis implicações legais, nomeadamente no âmbito do direito do arrendamento e do direito da propriedade, bem como na realização de obras por parte do seu arrendatário. A investigação baseia-se na doutrina e jurisprudência nacionais. Conclui-se com uma reflexão crítica sobre a posição do arrendatário na relação com o condomínio, comparando-o com as figuras do locatário financeiro e do arrendatário das partes comuns, avaliando as suas diferenças e semelhanças no contexto jurídico e contratual.
- Acidentes de viação e direito de regresso das seguradoras : a condução sob a influência de álcool (art.27º, n.º1, al. c) do DL n.º291/2007)Publication . Marques, Rita Barros de Sousa; Afonso, Ana Isabel da CostaA presente dissertação tem como objetivo estudar o regime geral do direito de regresso da seguradora no caso de acidentes de viação em que o condutor apresenta uma taxa de álcool no sangue superior à legalmente admitida, com foco específico na exigência de prova e alegação do nexo de causalidade entre danos decorrentes do acidente e a taxa de álcool no sangue. Esta questão foi objeto de um acórdão uniformizador no domínio do antigo diploma que regulava o regime do seguro obrigatório de responsabilidade civil (DL n.º522/85). No entanto, com a entrada em vigor do diploma atual (DL n.º291/2007) a interpretação e aplicabilidade do AUJ n.º6/2002 levanta a seguinte questão: é exigível ou não a prova do nexo de causalidade nos atuais pressupostos do art. 27º,n.º1, c) do DL n.º291/2007? Para uma compreensão mais fundamentada procedemos à análise da evolução do seguro obrigatório de responsabilidade civil, no direito europeu e nacional, comparação das diferenças dos dois diplomas supramencionados e estudo dos AUJ, n.º6/2002 e AUJ n.º10/2024. Constatou-se que não é exigível, à seguradora, alegar e provar o nexo de causalidade entre o acidente e a condução sob efeito de álcool, nos termos da redação do art. 27º, n,º1, c) do DL n.º291/2007, contrariamente ao que acontece no consumo estupefacientes ou outras drogas ou produtos tóxicos.
- Autonomia privada no âmbito da cessação do contrato de arrendamento urbanoPublication . Soares, Ângelo António De Salles Fernandes; Proença, José Carlos Barros BrandãoA presente dissertação versa sobre a amplitude do princípio da autonomia privada no âmbito da cessação do contrato de arrendamento urbano, incidindo particularmente sobre os aspetos do regime que conservam as maiores restrições e dúvidas interpretativas. Para o efeito, começamos por fazer um retrato da evolução do regime arrendatício português ao longo do último século, percorrendo em seguida o regime subjacente às diferentes formas de cessação do contrato de arrendamento urbano previstas na lei. Por fim, exploramos a possibilidade de inserção de cláusulas penais neste âmbito. Ao longo da nossa investigação, avaliamos as diferentes posições no seio da doutrina e da jurisprudência a propósito dos diferentes temas abordados, sobre as quais procurámos formular o nosso próprio entendimento e possíveis soluções numa perspetiva de jure condendo.
- Influencer marketing and generation Z : evolution, perception, and analysis of the Balenciaga casePublication . Acella, Elisabetta; Tavares, Patrícia Isabel Ramos Pego NunesIn a communicative landscape where the identity of luxury brands is increasingly played in the digital sphere, influencer marketing has established itself as a central strategic tool to activate trusting relationships with new generations. In particular, Generation Z - native digital, hyper-connected and value demanding - does not just consume content, but acts as a critical interlocutor, asking brands for transparency, inclusiveness and narrative coherence (Francis, 2018). In this scenario, the ability to build and maintain a perceived authenticity becomes crucial for the reputational legitimacy of brands, especially in times of crisis. This dissertation aims to investigate how authenticity in influencer marketing is interpreted and judged by Generation Z, through the analysis of the Balenciaga case and the controversial 2022 "Gift Collection" campaign. The primary objective is to understand how the communicative choices of influencers and brands influence the perception of authenticity and, consequently, the trust and symbolic adherence of younger consumers. To address these issues, the study employs a qualitative approach based on a netnographic methodology, complemented by a thematic analysis of user-generated content and public reactions on TikTok, Instagram, Reddit, and Twitter (Braun, 2006). The corpus analysed focuses on the responses of Generation Z to the Balenciaga campaign, with particular attention to the languages of moral indignation, irony, minimization, value dissociation and strategic role (or failure) of influencers in reputation management. The results show that authenticity, in the public perception, does not correspond to an objective quality but to a relational effect built over time, based on expressive consistency, personal exposure and correspondence between stated values and public behaviour (Lou, 2019). When this balance is broken, as in the Balenciaga episode, dynamics of mistrust, rejection, and symbolic boycott are triggered, often extending to influential figures who choose to remain silent or adopt ambiguous positions (Ackerman, 2021). Generation Z is particularly sensitive to communicative dissonances, interpreting any lack of stance or apparent opportunism as a sign of unauthenticity. The case study analysed highlights the fragility of communication strategies based on aesthetic provocation and performativity without ethical anchoring, demonstrating that engagement cannot be separated from shared values. Finally, dissertation the dissertation proposes an interpretation of the role of influencers not only as channels of visibility but as cultural mediators, whose effectiveness depends on the ability to represent a credible, consistent and recognizable identity (Casaló, 2020). In this framework, perceived authenticity is not a rhetorical attribute, but a structural requirement for building trust, emotional participation and brand defence in high public exposure contexts. The analysis therefore suggests the need for luxury brands to rethink their digital strategies according to logics of transparency, narrative coherence and cultural responsibility, aligning themselves with the expectations of an increasingly critical public, competent and actively involved in the construction of meanings.
- From declaration to perception : the role of the media in corporate social responsibility and human capital communication in the Brunello CucinelliPublication . Fusco, Francesca; Tavares, Patrícia Isabel Ramos Pego NunesThis research examines the processes of constructing, representing, and perceiving corporate ethical identity in the luxury sector, using the Brunello Cucinelli brand as a paradigmatic case study. In a context marked by growing attention to corporate social responsibility (CSR) and high symbolic exposure of brands, the study adopts a qualitative approach aimed at analyzing the narrative consistency between declared, represented, and perceived identities. This approach is embodied in the development of an original analytical matrix that integrates institutional data, media coverage, and user feedback on digital platforms. The results reveal consistency between the humanistic values proclaimed by the company and which they are perceived and recognised by the public. However, interpretative tensions and signs of ambivalence also emerge, highlighting the negotiated and non-linear nature of reputation, especially in participatory digital environments. The Cucinelli case shows how reputation in luxury is the product of sophisticated narrative governance, but also exposed to the risk of ‘rhetorical crystallisation’ and perceptual misalignment. The dissertation contributes to the theoretical debate on CSR as a performative discursive construct, proposing a perspective that interprets business ethics not as a stable attribute, but as a communicative act that requires consistency, openness to dialogue, and continuous renegotiation. Methodologically, the narrative triangulation model developed offers a replicable tool for analyzing corporate identity in highly symbolic contexts. Finally, at the managerial level, the study highlights the importance of systemic integration between storytelling, organizational culture, and monitoring of public perceptions in order to build an authentic, sustainable, and shared reputation.
- Modulatory effects of calcium-alginate encapsulated Akkermansia muciniphila in healthy and pathogen-infected faecal modelsPublication . Vedor, Rita; Barbosa, Joana C.; Machado, Daniela; Carvalho, Nélson Mota de; Costa, Célia Maria; Madureira, Ana Raquel; Gomes, Ana M.Introduction: Gut microbiota are the collection of bacteria, archaea and eukarya that colonise the gastrointestinal tract of animals and humans [1]. Prebiotics, probiotics and postbiotics have a positive e=ect on improving intestinal homeostasis by modulating both the microbiota profile and metabolic functions. This modulation may lead to beneficial changes in the production of specific organic acids and the consumption of extracellular ammonia. [2]. To study the e=ects of macro- or micronutrients, bioactive compounds and/or pre- or probiotics on the gut microbiota, in vitro digestion and colonic fermentation models have been developed. These models are a powerful tool to determine the e=ect of prebiotics or probiotics on the microbiota profile and/or the e=ect of these on metabolite production [4]. Objectives: The main goal of the study was to evaluate the influence of a pre-digested encapsulated next- generation probiotic, Akkermansia muciniphila, on gut microbiota during dysbiosis, caused by the oro-gastrointestinal pathogen Escherichia coli O157:H8. The specific aim is to determine whether the encapsulated probiotic has a therapeutic e=ect or primarily acts as a preventive measure. The analysis is focused on ammonia and short chain fatty acids (SCFAs) to understand the e=ect of the encapsulated A. muciniphila on gut microbiota metabolism. Furthermore, this work focused on evaluating the modulation of the gut microbiota in terms of microbial diversity. Conclusions: The incorporation of A. muciniphila, encapsulated in a calcium-alginate matrix, led to the modulation of both healthy and E. coli O157:H7-infected microbiota. This modulation resulted in an increase in the microbial diversity of the gut microbiota, a decrease in extracellular ammonia, and an increase in the production of SCFA, particularly acetate and propionate. In relation to total nitrogen ammonia, the results indicate that A. muciniphila takes in ammonia intracellularly, leading to a decrease in levels after 48 hours of faecal fermentation. The supplementation with calcium- alginate capsules containing A. muciniphila resulted in the modulation of microbiota diversity and metabolism, leading to increased levels of propionate and acetate, while butyrate was absent. This study found an increase in beneficial microbial genera, including Morganella, Bifidobacterium, and Bacteroidetes, indicating the restoration of gut microbiota homeostasis after a state of dysbiosis caused by infection with E. coli O157:H7.
