  • "Harassment and offenses to conversational agents : the case of BIA, the Feminist Chatbot"
    Publication . Ferreira, Joana Moreira; Silva, Susana Cristina Lima da Costa e; Martins, Carla Sofia Carvalho
    Purpose: this investigation aims to understand if chatbots can effectively induce prosocial attitudes and behaviors in users, throughout the customer journey in order to effectively help to educate the society as a whole. Methodology/approach: this case study is about the specific case of bia, a chatbot from bradesco, with almost 1 million clients. A sample of 10 brazilian people participated in this study. Thus, quantitative data was collected through interviews. Findings: the results showed that, being used in many different areas, chatbots can actually be a source of inspiration and public opinion making, working as a digital influencer. In fact, it is possible to induce pro-social attitudes and behaviors in users, mainly on the prepurchase and post-purchase phases of the customer journey. Thus, it was possible to conclude that it is possible to educate the population through a robot and that the population, in general, is available to learn in this way. Originality/value: we believe that this study adds a lot of value and has a huge amount of originality since, in fact, and to my knowledge, we are the first one deeply studying the social dimension of a chatbot, which is not, from the outset, expected. In fact, and by studying the case of bia, this study was able to conclude that, as the process unfolds, bradesco gained notion that bia could effectively be a digital influencer, with the power to educate the (brazilian) population on issues, and in a first phase, essentially related to harassment, bullying and which always end up intertwining with the empowerment of women.

  • Supplier partnership and intra-industry diversification : the case of Aston Martin’s Mid-Engine segment
    Publication . Brito, Duarte Ferreira de; Morais, Ricardo Alexandre
    Firms that compete in rapidly changing industries, such as the automotive one, frequently establish supplier’s partnership to gain a competitive advantage in the market. As a result, previous studies have examined supplier engagement in the development of new projects and concluded that it has an influence on project cost, development time, and project quality. Despite the relevant findings made by scholars in this regard, literature still lacks on explaining the effect of supplier involvement in the case of moving to a new segment within the same industry (Intra-industry diversification), where dependence on suppliers is intense, due to the novelty of the technology involved. Furthermore, it falls short of demonstrating how the supplier helps to accomplish the diversification drivers. Given that, this dissertation aims to respond to the following question: “How does the Supplier Partnership impacts the process of Intra-Industry Diversification?” For this purpose, a case study on Aston Martin was conducted mostly relying on primary data from interviews. This dissertation indicates that access to supplier capabilities has a favourable impact on product quality, cost, and development time. However, the heavy reliance on the partner's technology, the usage of improper industrial procedures, and the absence of contractual protection are factors that lead to the conclusion, contrary to claims by previous research, that partnerships with suppliers are not a synonym of better performance. This research findings are depicted in a framework that can be utilised in the future to evaluate the influence of supplier collaborations on new products development.

  • Servitization practices in healthcare : the case of Royal Philips
    Publication . Figueira, Mónica do Rosário Agrela; Ribeiro, Rita Moura Bastos de Almeida
    This research considers to what extent servitization in the healthcare industry has evolved and transformed in this sector. As healthcare costs have risen over the last few decades, significant attention has been directed to purchasing within this sector. Servitization is a promising business model for healthcare since it can reduce costs and risks when obtaining products and services. This study has the main objective to understand if healthcare manufacturers are already implementing this business model, if they do, which practices are they implementing, understand how the transformation process was and which changes were made. In addition, this study aims to understand the challenges the company faced and the benefits servitization can bring. A single case study in the form of research has been performed as a qualitative investigation on Royal Philips, a Dutch product manufacturing company operating in the global market that manufactures medical equipment. Besides that, the data was collected through semi-structured interviews and the second data was available on the Philips website. In addition, this study has an objective to contribute to the academic literature on servitization and the healthcare manufacturing industry since it is a topic that lacks data and research. The findings of this study were that Royal Philips is still in the initial phase of shifting to a more services-oriented business, and they are already implementing servitization strategies in some departments. The company faced some challenges during the implementation, but at the same time, this business model will bring many benefits. Still, the company intends to improve their business model in the coming years.

  • Dinâmicas da centralidade da religião e a Perturbação Obsessivo-Compulsiva (POC)
    Publication . Esteves, Jorge Agostinho Gomes; Leite, Ângela Maria Teixeira
    A religião, enquanto fenómeno individual e social, é uma dimensão intrínseca e das mais importantes do ser humano, sendo que toda a experiência religiosa compromete e abarca esse mesmo ser humano: dimensões cognitivas, afetivas, comportamentais e o seu contexto social. Ao abordar-se a religião como um conjunto de crenças que influenciam a cultura e modos de estar na vida de cada pessoa que nelas acreditam, perceciona-se, hodiernamente, que as ligações entre a religião e a saúde mental têm vindo a ser cada vez mais estudadas sendo que, entre as doenças psiquiátricas, a Perturbação ObsessivoCompulsiva (POC) é, sem dúvida, uma daquelas que tem vindo a merecer maior atenção. Posto isto, o presente trabalho visa compreender como as dinâmicas da Centralidade da Religião e a Perturbação Obsessivo-Compulsiva (POC) se influenciam mutuamente, numa amostra da população portuguesa, utilizando uma metodologia quantitativa, correlativa, transversal para o efeito e validando, para o contexto português, duas escalas religiosas. Os resultados revelam bons modelos de ajustamento à amostra para todos os instrumentos e revelam ainda uma relação significativa entre a obsessão-compulsão e a religiosidade.

  • Características do Conselho de Administração e manipulação de resultados em empresas cotadas na Euronext Lisbon
    Publication . Monteiro, João Pedro Ribeiro; Fonseca, Maria José Martins Lourenço da; Ribeiro, Ricardo Miguel Martins da Costa
    A presente dissertação tem como objetivo avaliar se certas características do conselho de administração das empresas portuguesas cotadas em bolsa têm, ou não, impacto nos níveis de manipulação de resultados das mesmas. Assim sendo, foi averiguado o impacto que a proporção de administradores não executivos e a presença de uma comissão de auditoria no conselho de administração têm nos níveis de manipulação de resultados, bem como, a distinção de funções entre o presidente do conselho de administração (chairman) e o diretor executivo (CEO). Para tal, a metodologia utilizada foi uma regressão linear múltipla para avaliar de que forma a manipulação de resultados está relacionada com as variáveis em estudo. Foi também utilizado o modelo de Jones modificado cross-sectional, sendo o princípio deste modelo determinar a manipulação de resultados através dos accruals discricionários. Os dados necessários foram extraídos da base de dados Refinitiv Eikon, com o complemento dos relatórios financeiros e de governo das sociedades, das empresas analisadas. A amostra é constituída por um agregado de 40 empresas portuguesas cotadas em bolsa, que integravam o PSI Geral entre 2016 e 2020. No que respeita aos resultados alcançados, este trabalho evidencia que, para a amostra em questão, a proporção de administradores não executivos no conselho de administração e a distinção de funções entre o chairman e o CEO não têm impacto nos níveis de manipulação. Por outro lado, foi possível concluir uma relação negativa entre a existência de uma comissão de auditoria integrada no conselho de administração e a prática de manipulação de resultados.

  • The role of website objective sensory features on consumers’ purchase intentions
    Publication . Ferraz, Maria Leonor Pereira Leite de Calheiros; Martins, Carla Sofia Carvalho; Machado, Joana Pinto Leite César
    In an online context, marketers can only benefit from sensorial marketing by exploiting visual stimuli through objective sensory features (OSF). These play a determining role in the brand-consumer connection, arousing emotions, feelings, and impressions in the consumer's subconscious. For decades, retail brands have been benefiting from sensory marketing to deliver a unique and engaging brand experience and consequently, increase sales. Previous research has shown that the OSF of a website is one of the key dimensions to impact user's emotions and impressions. However, the relationship between OSF and consumer purchase intentions (PI) lacks research. Moreover, the following two dimensions of OSF, picture size (PS) and menu titles and filters (M&FT) that impact the aesthetics of a webpage layout, will enhance the consumers’ response to a retail brand website. Nonetheless, there are still few empirical studies on this area. This dissertation aims to understand the role of OSF in customer PI through the manipulation of two of its dimensions, PS and M&FT, explain the importance of these dimensions in a website and provide guidelines for companies to take advantage of these crucial, relatively unexplored dimensions of OSF. This research was conducted through a random distribution of four questionnaires, representing a different combination of two OSF dimensions, applied to cosmetics online e-commerce. The collected data were analysed through a variance analysis with two factors for repeated measures (Factorial ANOVA) and three linear regressions to validate the hypotheses of the proposed model. The results demonstrate that an “affective website” increases consumers' PI due to the intermediating role of affective responses (AR) and trust. By using positive website’s OSFs through moderate-high stimuli, brands can induce In an online context, marketers can only benefit from sensorial marketing by exploiting visual stimuli through objective sensory features (OSF).

The results demonstrate that an “affective website” increases consumers' PI due to the intermediating role of affective responses (AR) and trust. By using positive website’s OSFs through moderate-high stimuli, brands can induce hedonic emotions and impressions such as interest and comfort and, consequently, trust. Finally, the results determined that the greatest OSF combination is large pictures and simple menus and, that the most determinant OSF dimension to influence consumers' ARs is PS. To conclude, this study provides a contribution to the literature by explaining the role of OSF in consumers’ PIs. Also, by presenting a set of relevant implications, it aims to increase the knowledge of companies and researchers on this relevant topic.

  • IFRS 8 : análise de value relevance para empresas do Euronext 100
    Publication . Fonseca, Miguel Rodrigues Tabau; Fonseca, Maria José Martins Lourenço da; Ribeiro, Ricardo Miguel Martins da Costa
    As alterações nos normativos contabilísticos são realizadas de modo a acompanhar o constante desenvolvimento das empresas, sendo que o seu objetivo basilar é de melhorar a informação divulgada para os seus utilizadores. A IFRS 8 entrou em vigor a partir de 2009 e, numa tentativa de aproximação à norma homóloga do normativo americano, alterou a abordagem na divulgação de segmentos, privilegiando uma divulgação da informação da mesma forma que esta é organizada internamente para questões de tomada de decisão e de alocação de recursos. Este estudo pretende avaliar o impacto desta nova norma para o mercado de capitais e, portanto, numa primeira fase foi essencial atestar que os segmentos divulgados por cada entidade são um instrumento valoroso para os investidores. Para tal, recorreu-se ao modelo de Ohlson (1995) para poder obter respostas em relação à relevância da informação por segmentos e, por outro lado, avaliar o impacto da IFRS 8 na divulgação dos segmentos e, consequentemente, nas suas implicações para os investidores. Os resultados atestam que a informação por segmentos é um recurso determinante para o mercado de capitais. Por outro lado, não foi possível aferir com confiança sobre o impacto da IFRS 8 no mercado de capitais, visto que, inicialmente os resultados apontavam para uma perda de relevância e, posteriormente, as análises de robustez indiciam o contrário. Face aos resultados obtidos, não é de excluir que o aumento de relevância se tenha circunscrito ao primeiro ano de aplicação da norma e que varie em função do número de segmentos relatados.

    Publication . Ferreira, Joaquim da Costa; Carvalho, Joaquim Félix de
    Esta dissertação aborda o diaconado permanente numa perspetiva histórica, bíblica, teológica e eclesiológica. A análise assenta numa metodologia sistemática e enquadra-se na hierarquia do magistério da Igreja. Este trabalho tem como principal objetivo esclarecer a identidade eclesial e histórica do diaconado. Em segundo lugar, analisam-se as mutações no ministério diaconal como adequação da Igreja às efemérides históricas e sociais. Por último, estuda-se a identidade teológica e espiritual do diaconado permanente, configurado em Jesus Cristo servo. Numa perspetiva mais estrita contrasta-se o diaconado permanente em Braga com o de outras dioceses - em foco estão fatores que influenciam a qualidade do diácono permanente numa estrutura sólida e identitária.

  • European Headache Federation (EHF) consensus on the definition of effective treatment of a migraine attack and of triptan failure
    Publication . Sacco, Simona; Lampl, Christian; Amin, Faisal Mohammad; Braschinsky, Mark; Deligianni, Christina; Uludüz, Derya; Versijpt, Jan; Ducros, Anne; Gil-Gouveia, Raquel; Katsarava, Zaza; Martelletti, Paolo; Ornello, Raffaele; Raffaelli, Bianca; Boucherie, Deirdre M.; Pozo-Rosich, Patricia; Sanchez-Del-Rio, Margarita; Sinclair, Alexandra; Maassen van den Brink, Antoinette; Reuter, Uwe
    BACKGROUND: Triptans are migraine-specific acute treatments. A well-accepted definition of triptan failure is needed in clinical practice and for research. The primary aim of the present Consensus was to provide a definition of triptan failure. To develop this definition, we deemed necessary to develop as first a consensus definition of effective treatment of an acute migraine attack and of triptan-responder. MAIN BODY: The Consensus process included a preliminary literature review, a Delphi round and a subsequent open discussion. According to the Consensus Panel, effective treatment of a migraine attack is to be defined on patient well-being featured by a) improvement of headache, b) relief of non-pain symptoms and c) absence of adverse events. An attack is considered effectively treated if patient's well-being, as defined above, is restored within 2 hours and for at least 24 hours. An individual with migraine is considered as triptan-responder when the given triptan leads to effective acute attack treatment in at least three out of four migraine attacks. On the other hand, an individual with migraine is considered triptan non-responder in the presence of failure of a single triptan (not matching the definition of triptan-responder). The Consensus Panel defined an individual with migraine as triptan-resistant in the presence of failure of at least 2 triptans; triptan refractory, in the presence of failure to at least 3 triptans, including subcutaneous formulation; triptan ineligibile in the presence of an acknowledged contraindication to triptan use, as specified in the summary of product characteristics. CONCLUSIONS: The novel definitions can be useful in clinical practice for the assessment of acute attack treatments patients with migraine. They may be helpful in identifying people not responding to triptans and in need for novel acute migraine treatments. The definitions will also be of help in standardizing research on migraine acute care.
