- The usage of digital products and their impact on sport-related engagement behaviours : an empirical investigation in the German professional soccer IndustryPublication . Stegmann, Jannik; Fernandes, DanielThe following study examines the relationship between fans’ usage of digital products and their sport-related behaviours in the German professional soccer industry. Besides the general relationship between the two variables, a closer look is taken at the impact of the usage of virtual and augmented reality on the attendance of sporting events, the usage of streaming on watching games, the usage of e-commerce on the purchase of team products, and the usage of online news services on reading sports news. Further, the role of satisfaction as a mediator is analysed in the respective relationships. Findings from a survey indicate that overall sport-related behaviours are not predictable from the usage of digital products in general. Still, the usage of the individual digital product shall be regarded when considering the respective sport-related behaviours – significant correlations between the specific digital product and their corresponding sport-related behaviour were found. Although satisfaction is not confirmed to be a mediator, usage of digital products is a strong predictor regarding the satisfaction of the individual’s usage.

- The differences between the male gender and the female gender in the purchase intention of cosmetic productsPublication . Ventura, Iris; Braga, João NizaThe male gender participation in the cosmetic industry has grown significantly in the recent years. This tendency can be attributed to a shift on the gender social norms attributed to men and woman that has led to an increasing concern for the physical appearance from the male gender. Consequently, due to this increase of interest of the male gender in the purchase of cosmetic products it is important to study more about this emerging segment. Since the Online channel provides more privacy to the consumer when on the act of purchasing because it can be done with no interaction with other people, it would be expected for the male gender to prefer to engage in the purchase of stereotypical products of the female gender online instead of in-store. The literature, as it is further developed during this thesis, supports this claim, however the results obtained show that this might not be the case. It would also be expected that individuals of the female gender would be more likely to purchase cosmetic products in-store since the literature supports that this gender seems to be more concerned with factors such as websites keeping their costumer profile, compared to man. The data proves that this is the case however not for all the products studied.
- The effects of peptide receptor radionuclide therapy on the neoplastic and normal pituitaryPublication . Marques, PedroPituitary neuroendocrine tumours (PitNETs) are usually benign and slow-growing; how- ever, in some cases, they may behave aggressively and become resistant to conventional treatments. Therapeutic options for aggressive or metastatic PitNETs are limited, and currently mainly consist of temozolomide, with little experience of other emerging approaches, including peptide receptor radionuclide therapy (PRRT). Somatostatin receptor expression in PitNETs explains the effectiveness of somatostatin analogues for treating PitNETs, particularly those hypersecreting pituitary hormones, such as growth hormone or adrenocorticotropic hormone. The expression of such receptors in pi- tuitary tumour cells has provided the rationale for using PRRT to treat patients with aggressive or metastatic PitNETs. However, the PRRT efficacy in this setting remains unestablished, as knowledge on this today is based only on few case reports and small series of cases, which are reviewed here. A total of 30 PRRT-treated patients have been thus far reported: 23 aggressive PitNETs, 5 carcinomas, and 2 of malignancy status unspecified. Of the 27 published cases with information regarding the response to PRRT, 5 (18%) showed a partial response, 8 (30%) had stable disease, and 14 (52%) had progressive disease. No major adverse effects have been reported, and there is also no increased risk of clinically relevant hypopituitarism in patients with pituitary or non-pituitary neuroendocrine tumours following PRRT. PRRT may be regarded as a safe option for patients with aggressive or metastatic PitNETs if other treatment approaches are not feasible or have failed in controlling the disease progression, with tumour shrinkage occurring in up to a fifth of cases, while about a third of aggressive pituitary tumours may achieve stable disease. Here, the data on PRRT in the management of patients with aggressive pituitary tumours are reviewed, as well as the effects of PRRT on the pituitary function in other PRRT-treated cancer patients.
- The future of work : the impact of artificial intelligence on the wellbeing of whitecollar employeesPublication . Owsianka, Jill Lais Corsato; Almeida, Filipa deGiven the upward trend in automation, as seen on a mechanical level in manufacturing plants, it is predicted that the next phase will involve artificial intelligence working in conjunction with human employees within the office environment. This research will explore how these predicted future scenarios of human whitecollar employees working alongside artificial intelligence agents impacts their wellbeing. This research follows an experimental approach where participants are exposed to two different scenarios manipulating the independent variable: working with and without an artificial intelligence team member and measures participants’ wellbeing. The study’s findings indicate that there is no significant difference between the two groups. Implementing artificial intelligence as a new coworker does not affect the employee’s wellbeing significantly different than a new human coworker. Furthermore, attitudes towards AI do not mediate the relationship between type of coworker and the participants’ wellbeing.
- The influence of automation in support for Universal Basic IncomePublication . Monteiro, Mariana Amaro de Sousa Coelho; Almeida, Filipa deTechnology is advancing at unprecedent rates and Automation and AI have the potential to expand the economy beyond human production, as such, Universal Basic Income (UBI) arises as a political measure to mitigate the effects of that scenario. Nonetheless, opinions towards UBI are divergent and may be influenced by different socioeconomic and phychologial factors. This dissertation explores the influence that the introduction of a future automated society has on individual’s support for UBI. Additionally, this study investigates the role of specific beliefs (Meaningfulness of Work and Meritocracy) as well as of Job Automation Risk as moderators in that relationship. Results show that the introduction of a future automated scenario positively influences participant’s opinions towards UBI. Results also reveal that the more individuals believe in Meaningfulness of Work, the less they are prone to support UBI. Finally, the study found no evidence of moderation by Meritocracy and Job Automation risk in the relationship between the introduction of a future automated society and support for UBI.
- Impact of Covid-19 on process and structure organization, new ways of work, and sustainable measures adopted : the case of SiemensPublication . Barreiras, Maria de Mello Vieira; Reis, Ricardo César Ribeiro Ventura FerreiraThis dissertation is a case study of Siemens S.A.'s Global Business Services business in Portugal. The case seeks to answer the question, "How did the Covid-19 pandemic affect Siemens S.A., specifically the GBS department, in terms of organizational processes and sustainable measures adopted?". Five interviews were conducted at various levels of the hierarchy to answer this question, analyzing two distinct temporal moments: the beginning of the pandemic (March 2020) and the return to normalcy (mid-2022). This study's pedagogical structure aims to provide a detailed understanding of how the company reorganized during the two chronological moments of the crisis. However, since the study is based on a real-life example, it is an illustrative case and is not intended to put the reader in a dilemma. The result made us conclude that the company was structurally and operationally prepared to face the crisis. Being a technological organization made confronting this unknown reality much easier because it provided all employees with the necessary tools to avoid customer service interruptions. However, it was also clear that how the organization communicated its strategy regarding the hybrid model to be used impacted team management. As a result, a new theme emerged in the debate, generating noise and discord and requiring managers to manage their teams operationally and emotionally.
- Will the small be feeding us all? An analysis of alternative food networks in AustriaPublication . Beck, Joana; Leglise, LaureSocial innovation has gained growing relevance from policymakers, civil society, organisations and the scientific community to address the pressing problems of today. Especially our current food systems are environmentally, economically and socially unsustainable and in desperate need of change. Factors like growing consumer distrust and economic and political crises urge the need to change global food chains. AFNs are considered a bottom-up response to those deficiencies. Scholars have stressed the need to investigate the practical implementation and impacts of SI initiatives, especially in the agricultural sector. Moreover, the practical nature and the conceptual ambiguity of SI have stressed the need for more empirical research to derive valuable insights into how these initiatives can help transform the agro-food system. The research question for this study is: “How can alternative food networks produce social and environmental outcomes? The results show that AFNs are producing SI outcomes, especially in terms of returning to traditional practices, enhancing biodiversity and soil health. Due to the close relationship with their consumers, these initiatives also promote participation and knowledge-sharing. Communication and transparency are crucial factors for success, an AFNs could benefit from improving their online presence in order to share their values and mission. Moreover, the study shows that knowledge structures and organisational capabilities need to be implemented.
- The daily struggle of a consumerist culture : who are we without our possessions? : a study of an effective strategy to boost product salesPublication . Castelo, Rita; Fernandes, DanielAccording to research on extended self and compensatory consumption, consumption is a way of expressing, reinforcing, and resolving identity discrepancies (Belk, 1988). The investigation suggests that there is a glaring gap between these domains and marketing, making it crucial to develop additional research to better understand how organisations can more effectively interact with consumers. In this way, the present dissertation seeks to determine an effective strategy to persuade the consumer to buy a certain product. First, the two most important factors in the decision-making process were determined (the first study), and then the accuracy of the results was assessed in an A/B test (the second study). The dissertation proposes that highlighting personal discrepancies, which in turn highlight needs, can be an effective way to increase sales. It suggests that the discrepancy arises through the mental perception of the product, i.e., when campaigns make consumers visualise their ideal selves and experience emotions associated with that visualisation. Associated with each discrepancy is a need that the consumer wants to satisfy. The product must then be positioned as the optimal solution to bridge the gap between the consumers’ current selves and their ideal selves and as a means of fulfilling (partially or totally) their needs. This strategy results from the fusion of three important marketing theories: extended self, compensatory consumption, and Maslow's hierarchy of needs, which are believed to be interconnected, with the first two being a way to fulfil the last-mentioned.
