Software-based assets: a new perspective on the concept of software assets
Publication . Simões, Ivo; Bernardo, Maria do Rosário ; Isaias, Pedro
Este artigo propõe o conceito de Software-Based Assets (SBAs) como uma categoria emergente de software assets, distinta das abordagens tradicionais. Apresenta-se um modelo de gestão orientado à entrega de valor numa perspetiva multidimensional, que inclui inovação, capacitação, gestão em ecossistema protegido e maximização na diferenciação estratégica.
Propõe-se ainda um modelo de maturidade que permite avaliações com uma comunicação em níveis transversais de entendimento. Os resultados demonstram que os software assets constituem recursos estratégicos subvalorizados e mal geridos, de modo geral, nas organizações, sendo necessária uma abordagem que reconheça o seu potencial e extraia o máximo das suas múltiplas dimensões de valor.
Virtual assistants in a digital governance environment
Publication . Pimentel, Luis; Reis, Arsenio; Bernardo, Maria do Rosário ; Rocha, Tânia; Barroso, João
Technological developments have had a major impact on the intensive use of electronic equipment, networked or connected to the internet, factors that have boosted the emergence and growth of cybercrime. Measures to mitigate and combat the phenomenon, taking into account its complexity and specificity, must involve all public entities with responsibility in the sector, in a global effort to promote digital literacy in the areas of cybersecurity and computer crime prevention. These comprehensive actions should use digital technologies based on artificial intelligence (AI), such as virtual assistants, whose characteristics allow the massification of information transmission, while enhancing the digital inclusion of users. Government entities are engaged in adopting technologies based on chatbots, with their presence in several areas of public administration. Despite the evolution, these resources have not yet been made available by the entities responsible for mitigating computer crime. On the other hand, although there are government programs aimed at increasing the digital skills of citizens, namely regarding the protection of devices, digital content or personal data, they are not designed for the specificities of cybercrime. In this context, a system based on chatbots, implemented in a digital governance context, by law enforcement agencies, with resources shared with other government entities can contribute to the prevention of cybercrime.
Impact of a master data management framework to trigger data governance maturity: a systematic literature review
Publication . Guerreiro, Leonardo; Martins, José; Bernardo, Maria do Rosário ; São Mamede, Henrique; Branco, Frederico
Data governance plays a crucial role for organizations aiming to improve data quality, security, and compliance, yet research reveals ongoing challenges in implementation, maturity, and the practical effectiveness of current frameworks. Despite the availability of numerous concepts, models, and assessments, their actual impact and relevance remain fragmented and insufficiently explored. This Systematic Literature Review (SLR) investigates how data governance frameworks influence maturity and identifies the factors that drive their effectiveness. Through the synthesis of existing research, the review aims to clarify the relationship between governance frameworks and maturity levels, highlight operational benefits, and examine implementation challenges, ultimately contributing to both academic understanding and practical advancements in data governance. Analyzing the most relevant studies, the review seeks to uncover the main governance mechanisms, frameworks, and trends shaping this field, with a central question in focus: How can a structured master data management framework improve data governance maturity?.
"The implementation of public chatbots to raise awareness of computer crime"
Publication . Pimentel, Luis; Bernardo, Maria do Rosário ; Rocha, Tânia
Recent technological advancements have increased computer crime, requiring public authorities to implement structured mitigation strategies. While initiatives exist to improve digital literacy on device security, they must also address the complexities of computer crime. Using Design Science Research, this study investigated the applicability of chatbots to raise awareness of computer crime in a public administration setting. A systematic literature review highlighted the issue’s relevance and identified knowledge gaps. A scoping review gathered concepts, methodologies, technologies, architectures, and tools for developing and evaluating an effective chatbot. The design and development phase included a detailed proposal for a sophisticated chatbot architecture.
During the demonstration and evaluation phases, the utility of the chatbot was tested in the domain of conversational flow efficiency and usability. The study’s primary results and contributions are to assess the chatbot’s effectiveness in raising awareness of computer crime on public websites. Future work should focus on implementing the chatbot in the actual context of public administration, proposing a network of specialized conversational assistants, and improving public service interoperability to enhance computer crime awareness.
A azulejaria barroca e Rococó: temas, espaços e programas decorativas
Publication . Câmara, Maria Alexandra Gago da; Balsa, Joana
A azulejaria do século XVIII constitui uma das expressões mais distintivas do património artístico português. Tratando-se de um vastíssimo período de produção azulejar no nosso país, torna-se importante evidenciar algumas questões que caracterizaram este longo tempo, tais como a cronologia, a evidência de alguns conjuntos quer civis, quer religiosos incluídos no arco temporal, privilegiando sempre a relação que se estabelece entre o programa decorativo e iconográfico e a arquitetura. E por fim, os meios de difusão, e a significação da circulação dos modelos e das gramáticas decorativas.
