Ciência de Dados na Indústria Cerâmica
2026-02-23 - Silva, Gonçalo Filipe Aguiar da
O presente trabalho relata o desenvolvimento e aplicação, em Python, de duas
soluções de análise de dados na indústria cerâmica, no Instituto de Soldadura e Qualidade
(ISQ).
Com o objetivo de colmatar a falta de estudos neste setor, o documento explora os
benefícios teóricos e práticos do estudo detalhado do funcionamento de fornos industriais,
destacando também o processo de desenvolvimento das soluções.
Recorreu-se a uma extensa revisão da literatura, juntamente com perspetivas sobre
a análise de dados e a integração desses elementos.
As soluções incidiram sobre dois conjuntos de dados: um com parâmetros de
funcionamento de fornos cerâmicos de diversas entidades portuguesas e outro com dados
de um forno adicional.
Ao longo do relatório, são abordados os principais obstáculos enfrentados, bem como
interpretações e medidas corretivas propostas para os fornos em estudo.
Este trabalho confirma os benefícios previstos no apoio à tomada de decisão. Com a
sinergia entre a recolha dos dados e o seu estudo gráfico, foram identificados incrementos
de eficiência ao transformar dados brutos em informações relevantes.
Por fim, o estudo demonstra o potencial da análise de dados para futuras
investigações na cerâmica, contribuindo para reforços na otimização de processos,
sustentabilidade e competitividade do setor.
Playing for profit, healing for survivel: The Economics, Risks and Legal Protection of Portuguese Professional Football
2025-12-15 - Pereira, António Miguel Gouveia de Brito Pinheiro
Sport is increasingly recognised as a major economic and social phenomenon, contributing
to employment, tourism, infrastructure, and national identity. Within this context, football
stands out as the most global and economically significant sport, combining mass
popularity, commercialisation, and international reach.
Within this landscape, Portuguese professional football represents a distinctive case. Unlike
the major European leagues, where revenues largely derive from ticket sales, broadcasting
rights, and sponsorships, Portuguese sport societies rely structurally on the transfer market,
positioning players as their most valuable assets in a producer-driven economy. Clubs play
for profit by developing and exporting talent, yet their survival depends on the health,
availability, and legal protection of those same players. Injuries, therefore, emerge as a
critical disruptor of financial stability, sporting performance, and institutional governance.
The overarching objective of this research is to underscore the pivotal role of players in the
Portuguese football industry, where the business model predominantly depends on the
transfer market and relies on homegrown talent within a producer-driven structure. To
achieve this, the thesis pursues four objectives: (i) to analyse the economic structure of
Portuguese professional football and the role of players as strategic assets; (ii) to identify
and evaluate predictors of injury severity using artificial intelligence applied to real-world
data; (iii) to assess the incidence and severity of injuries across competitive tiers and identify
risk patterns; and (iv) to critically evaluate the legal and regulatory framework of
occupational risk and insurance, with a particular focus on Law No. 48/2023 and its
comparative implications. These objectives were addressed through four scientific articles,
each dedicated to one of these dimensions, providing complementary perspectives on the
economics, risks, and regulation of Portuguese professional football
Methodologically, the thesis adopts an interdisciplinary and predominantly deductive
approach, combining quantitative and qualitative techniques. It integrates financial and
macroeconomic analysis of revenues and transfers; predictive modelling through a deep
neural network applied to 1,639 injury records across five seasons; epidemiological and
statistical methods, including descriptive, inferential, and cluster analysis, to examine injury
patterns; and qualitative legal and regulatory analysis, situating Portugal’s high-risk
insurance regime in comparative perspective with other major jurisdictions.
Taken together, the four studies confirm that football players constitute the most important
assets of Portuguese professional football, with their economic rights standing as the most
highly valued intangible within the transfer-driven business model, directly shaping both club
sustainability and macroeconomic outcomes. The thesis advances theoretical
understanding by demonstrating the interdependence of economics, clinical risk, and legal
governance in a system where injury risk undermines asset value and exposes structural
fragility. Empirically, it provides original evidence on the predictors of injury severity, the
incidence and distribution of injuries across leagues and player profiles and confirms that
Portugal has established a unique work accident insurance system for professional football
players, offering stronger protection than comparable international frameworks. Practically,
it offers guidance for clubs, policymakers, and insurers, highlighting the need for balanced
financial management, data-driven injury prevention and rehabilitation, and statutory
protection that secures player welfare, financial resilience, and competitive fairness.
Empowering Digital Entrepreneurship Intention: Unveiling the Role of Education
2026-02-20 - Lopes, João M.; Gomes, Sofia; Farinha, Luís; Sampaio, Carlos
Entrepreneurs’ digital entrepreneurial capabilities can enhance the interaction between digital innovation and digital entrepreneurship. This study explores the influence of digital entrepreneurial capabilities (digital entrepreneurial education, alertness, and knowledge) on the digital innovative attitude and entrepreneurial intention of higher education students. A sample of 417 Portuguese higher education students was collected, and the partial least squares method was applied to the research model. The results showed that higher education students’ innovative digital attitudes and digital entrepreneurial intentions are positively influenced by their digital entrepreneurial alertness and knowledge. Digital entrepreneurial education was not significant in affecting innovative digital attitudes. However, when an innovative digital attitude acts as a mediator, the relationship between digital entrepreneurial intentions and digital entrepreneurial capabilities is stronger. Thus, the importance of digital entrepreneurial education, alertness, and knowledge as precursors to the intention of digital entrepreneurship is emphasized, as well as the importance of these capabilities in promoting digital innovation. The main contribution of this study is to demonstrate the mediating role of the digital innovative attitude in the association between digital entrepreneurial capabilities and digital entrepreneurial intention. These effects intensify the associations between digital entrepreneurial alertness and digital entrepreneurial knowledge with digital entrepreneurial intention, shedding light on how digital entrepreneurship capabilities shape students’ innovative digital attitudes and entrepreneurial intentions and enable articulate digital innovation with digital entrepreneurship.
