- A violência doméstica e a aproximação policial: uma nova (re)organização na vidaPublication . Marques, Maria Madalena Ferreira; Felgueiras, Sérgio Ricardo Costa ChagasO flagelo da violência doméstica (VD) é um dos principais crimes registados pela Polícia de Segurança Pública e apesar do muito trabalho que se tem feito, os números refletem que este tipo de crime continua evidenciado, inclusive continuam a registar-se a morte de vítimas neste contexto e uma das funções da polícia é preservar a segurança da vítima. Assim, o presente estudo procurou investigar se os policias que trabalham com este tipo de crime, nomeadamente os policias da proximidade e da investigação criminal conseguem contribuir para a vítima se sentir mais segura ou, pelo menos, ter a perceção de maior segurança, e se esta intervenção contribui para a vítima conseguir mais capacidade para iniciar um novo projeto de vida sem violência. Foi adotada uma abordagem qualitativa e tendo como base um guião semiestruturado, foram realizadas 14 entrevistas a policias do Comando Distrital da Polícia de Segurança Pública, que depois de transcritas compuseram o corpus, que foi submetido a análise de conteúdo. Os resultados permitiram verificar que as principais preocupações dos policias foram sobre a caracterização das intervenções policiais em violência doméstica e acerca da forma como veem as vítimas de violência doméstica, nomeadamente os contributos que dão para a mudança do seu projeto de vida, sem violência, além do cuidado que procuram ter no sentido de aumentar o sentimento de segurança e proteção das vítimas. Concluimos que, a grande preocupação dos polícias passa por promover a segurança das vítimas.
- Comparison between osseodensification and conventional osteotomy protocol for implant site preparationPublication . Gaspar, João Rui Carvalho; Mendes, José João; Neiva, RodrigoOral rehabilitation with endosseous implants is a safe and effective treatment option which is associated with high success rates. Implant stability is a critical factor for the clinical success of rehabilitation and includes primary stability (mechanical engagement obtained upon insertion into the bone, holding the implant in place), and secondary stability (biological fixation that occurs due to the new bone formation during healing, resulting in osseointegration). It has been shown in the literature that implant micromotion exceeding 50 to 150 μm during healing period can lead to fibrous tissue interposition at the boneimplant interface and consequent failure in the osseointegration process. Therefore, according to several authors, high degrees of primary stability are associated in the literature with superior and higher probability of osseointegration. Furthermore, there are several parameters that must be considered during the implant site preparation, which should be as atraumatic as possible to maintain cell viability. The preservation of the bone structure and collagen matrix, together with the increase in primary stability, also demonstrated the potential to accelerate the post-surgery healing process. In 2015, a novel surgical technique for implant site preparation termed osseodensification (OD) has been introduced. It is a non-subtractive drilling technique that preserves bone by using specially designed burs in counterclockwise (CCW; noncutting motion) with copious irrigation. Contrary to conventional drilling techniques, OD promotes bone compaction along the osteotomy walls and into the trabecular spaces, increasing the bone density at the site. Several authors reported that this technique can help to obtain higher values of primary stability and implant insertion torque, especially in less dense bone. However, these drills have a dual-mode action since they may also be used in clockwise direction (CW) in which they have cutting capacity like any other system. Since it pushes the bone instead of removing it, OD has enormous potential in the field of oral implantology in different indications, namely in ridge expansion, post-extraction implant placement or maxillary sinus floor elevation (SFE) by crestal approach with high predictability and reduced morbidity, compared to alternative techniques.The main objective of this doctoral project was to contribute to advance knowledge regarding the OD technique and to validate its versatility and application in different clinical situations. In this sense, we decided to perform a systematic review and meta-analysis, with the aim of comparing implant stability between site preparation with OD compared to the conventional osteotomy protocol. This review was the first to exclusively analyze human data and demonstrated that OD consistently achieved higher values of primary and secondary stability (4-6 months after implant placement) compared with conventional drilling (Chapter 3). In addition, we had the opportunity to participate in an international multicenter retrospective clinical study, with colleagues from five nationalities, which confirmed the ability of OD to expand the interradicular septum for the post-extraction implant placement in molars. Furthermore, this study also allowed the introduction of a new molar socket classification, which can be used by the scientific community and facilitate communication between peers (Chapter 4). Finally, according to the current evidence, OD appears to have, in fact, enormous potential for SFE. However, there is still a lack of scientific studies with adequate methodology that effectively allow the OD technique to be considered as a valid alternative to the classic lateral window technique (LW), especially in highly resorbed posterior maxilla in which it continues to be considered the gold standard. Therefore, we decided to conduct a randomized clinical trial with the aim of comparing the effectiveness and impact on patients' quality of life of SFE with OD versus LW, both with simultaneous implant placement when residual bone height (RBH) < 4 mm. The results showed that, although both techniques were similarly effective, OD significantly outperformed LW in pain experience, impact on self-perceived quality of life, surgery duration, postoperative edema and analgesics intake (Chapter 5). In conclusion, OD represents a paradigm shift in implantology in terms of implant site preparation. This thesis confirms its clinical potential and versatility in different situations, from optimizing the implant site alone to bone expansion or SFE by crestal approach. Furthermore, our results position OD as a real and valid alternative to the LW technique in extreme cases with reduced RBH, with a significant improvement in patient experience.
- Prevalência De Estirpes Multirresistentes De Escherichia Coli, Isoladas De Vitelos Com Diarreia Neonatal Oriundos Dos Departamentos Do Cantal, Haute-Loire, Loire E Puy-De-Dôme (França)Publication . Provost, Clémence Marie Camillle; Da Silveira, Maria Eduarda MorenoEscherichia coli Enterotoxigénica (ETEC), apresenta uma elevada prevalência na Diarreia Neonatal Bovina (DNB). Esta é uma doença mul=fatorial afetando principalmente os vitelos nas primeiras semanas de vida, levando a elevadas perdas económicas. A par=r de dados clínicos cedidos pelos Laboratórios de TERANA, França, foi construída uma base de dados, que permi=u analisar o perfil de virulência e de susce=bilidade a an=microbianos, entre o período de 2016 a 2022 em 2367 isolados de E. coli provenientes de amostras fecais de vitelos suspeitos de serem portadores de DNB. A iden=ficação dos isolados foi realizada por API 20E e Maldi-ToF MS e a pesquisa de fatores de virulência (FV) fimbriais e não fimbriais por método de aglu=nação em lâmina. Este estudo pretendeu ainda verificar a possível relação entre a presença de FV e perfis de mul=rresistência (MDR) nos isolados em estudo. No total dos isolados observou-se que 59% (1388/2367) eram portadores de FV. CS31A foi o FV mais prevalente (61%), seguido de F5 (20%), F17 (8%), F41 e F6 (2%). Rela=vamente ao perfil de resistência a an=microbianos (AMR), observou-se uma elevada prevalência de isolados portadores de resistência a aminoglicosídeos e aminopenicilinas (89%); tetraciclinas (80%); quinolonas (48%) e sulfonamidas (42%). Em outras categorias destacou-se a resistência à cefuroxima (26%); flumequina (34%), florfenicol (27%) e à colis=na 1% (p<0.05). Verificou-se que 85% dos isolados (2010/2367) eram portadores de perfil de MDR, dos quais 61% (1233/2010) transportavam FV. Observou-se ainda que o perfil MDR mais prevalente incluía resistência simultânea a aminopenicilinas, aminoglicosídeos e tetraciclinas (43,34%), associado ao FV CS31A (47%), seguido de aminoglicosídeos, tetraciclinas e sulfonamidas em isolados não portadores de FV (43%) (p<0.05). Perante os resultados é possível concluir que bovinos portadores de DNB por ETEC podem cons=tuir um reservatório não só de E. coli portadora de FV mas também de perfil MDR associado ao FV não fimbrial CS31A, ou não associado a qualquer FV. O facto de poderem ocorrer eventos de transferência horizontal poderá contribuir para a disseminação de FV associados a perfil MDR para E. coli não patogénica (NPEC) endógena da microbiota intes=nal, quer dos animais, quer do Homem, cons=tuindo um risco de saúde pública e exigindo medidas de monitorização não só de es=rpes de ETEC mas de NPEC .
- Why are stans stans?Publication . Correia, Lucas Azevedo Araújo; Salomão, MiriamIn contemporary culture, the phenomenon of stan behavior has emerged as a prominent aspect of fan engagement and loyalty. Stemming from Eminem's 2000 song "Stan", the term denotes individuals who exhibit intense and sometimes obsessive loyalty towards specific celebrities, artists, or pop culture icons. Drawing upon theoretical frameworks such as parasocial relationships theory, psychological theories of attachment and consumer behavior in the music industry, this empirical research adopted a qualitative approach delving into the experiences of why individuals become stans. Through a qualitative research design, this study delves into the experiences and perceptions of individuals who identify themselves as stans. One of the main findings of this research is that stans often immerse themselves in unhealthy behaviors, and some are reluctant to admit their obsessive attitude. Also, fans exhibit remarkable resilience in maintaining emotional ties with artists, frequently explaining their continuous support with significant confidence in the artist's integrity and a sense of shared understanding. This phenomenon exemplifies a form of brand (or artist) loyalty whereby dedicated followers, commonly referred to as stans, consistently support and promote their favored celebrities. This steadfast loyalty frequently influences broader consumer trends and market dynamics within one of the world's largest industries. This research contributes to the existing literature by providing a nuanced understanding of stan behavior and its implications for brand loyalty. Moreover, it offers valuable insights to the music industry, highlighting how such intense fan loyalty can be harnessed to drive consumer engagement and market influence.
- Understanding the role of TikTok´s user-generated content on gen Z women: purchasing intentions in the sustainable fashion industryPublication . Costa, Joana Rita Pereira da; Dias, Joana CarmoNowadays, social media, particularly platforms like TikTok with its massive Generation Z user base, has become a breeding ground for influencer marketing. As the sustainable fashion movement gains traction, replacing environmentally damaging fast-fashion habits, understanding consumer behavior in this space becomes crucial. Therefore, the general goal of this dissertation is to understand how Gen Z women's engagement with user-generated fashion content on TikTok affects their purchasing decisions within the sustainable fashion sector. To achieve this aim, a qualitative approach was adopted, involving 14 semi-structured interviews, making use of a diverse sample of Generation Z women. Data analysis was conducted utilizing Braun & Clarke’s Content Analysis technique. Results reveal that Generation Z places greater trust in authentic user-generated content over sponsored content associated with brands. Furthermore, Generation Z demonstrates a growing awareness of sustainable practices. Finally, the purchasing intention is not necessarily influenced by usergenerated content, as there remains a consistent absence of sustainable fashion content on TikTok.

- The strategy for global reach a case study of EstufazoresPublication . Pinheiro, Maria Beatriz da Cunha Pereira Ramos; Nogueira, MafaldaInternationalisation is a complex phenomenon for most companies, especially small and medium-sized enterprises (SMEs). Often, a lack of resources, experience or knowledge can jeopardise business expansion across borders. In this sense, there are external agents, known as consultants, with specialised knowledge, strategic contacts and know-how, who provide support to these companies, helping them before, during and after the internationalisation process. In order to understand how a consultant can support a company in the development and implementation of an internationalisation strategy, this research is based on a case study of the relationship between CH Business Consulting and Estufazores. In order to answer the research problem, a literature review was initially carried out focusing on the themes of the internationalisation process, international marketing and the role of consultancies in business internationalisation. Since this is a case study, a qualitative approach was adopted, using document analysis and semi-structured interviews with three CH Business Consulting employees and one Estufazores employee. Finally, from the triangulation of the data, it was concluded that, despite the strategies developed by CH Business Consulting, Estufazores' internationalisation faced significant challenges, underlining the need for meticulous preparation and continuous adaptation if SMEs are to achieve success in international expansion.
- O impacto das características dos influencers digitais na intenção de compra de skincare dos seus seguidoresPublication . Caramalho, Sofia Bragança de Miranda Azevedo; Falcão, DianaO marketing digital tem vindo a assumir um papel cada vez mais presente nas estratégias que as empresas adotam para conseguir alcançar o seu público. Neste contexto, e tendo em conta a crescente adesão às redes sociais, a parceria com influencers digitais tornou-se fundamental às empresas, devido ao impacto que estes possuem na intenção de compra dos seguidores. Dos variados temas abordados pelos influencers, destaca-se, no âmbito da beleza, os cuidados com a pele (skincare). A literatura aponta para falta de investigações que apliquem os mesmos estudos noutras áreas para além da moda, como o setor de beleza. Assim, a presente dissertação pretende estudar o impacto da Confiabilidade, o Expertise, a Atratividade, a Similaridade e os Patrocínios dos influencers na intenção de compra de produtos de skincare dos seus seguidores. A literatura mostra que estudos idênticos concluíram sobre o impacto positivo da Confiabilidade, do Expertise, da Atratividade, da Similaridade na Intenção de Compra, ao contrário dos Patrocínios que evidenciam um impacto negativo. Foi adotada uma metodologia quantitativa, e a recolha dos dados foi feita a partir de dados primários, baseada na aplicação de um questionário estruturado. A amostra é constituída por 265 inquiridos. Os resultados obtidos com esta investigação concluem sobre o impacto positivo da Confiabilidade, da Atratividade, da Similaridade e dos Patrocínios na intenção de compra de skincare, mas não fornecem evidências estatisticamente significativas para debater sobre o impacto do Expertise na intenção de compra. Este estudo revela-se um contributo útil uma vez que pôde concluir, através da definição de quatro subamostras, que a comunicação dos influencers, poderá ser ajustada aos segmentos, uma vez que são valorizados atributos diferentes em cada um deles.
