Publicação Acesso Restrito Teachers’ perspective on the implementation of GDPR in schools: A design-oriented case study2024-06-01 - Marchetti, Emanuela; Valente, Andrea; Witfelt, Claus; Amo-Filva, Daniel; Garcia-Holgado, Alicia; Garcia-Holgado, Lucia; Vidotto, Elisabetta; Garzotto, Maria Elena; García-Peñalvo, Francisco José; Escudero, David Fonseca; Orehovacki, Tihomir; Krasna, Marjan; Pesek, Igor; Ruzic, Ivana; Fraoua, Karim Elia; Moreira, FernandoIn this paper, we are interested in investigating how the introduction of GDPR has affected the teachers, with respect to how the new rules have altered their practices, which issues or challenges they have experienced, and which strategies they have developed to overcome such issues. Proceeding from an ecological perspective, we look at schools as complex ecologies, in which every change, happening at various scales and involvement levels, affects each actor in specific ways and at different degrees, altering their practices and mutual relations. Activity theory is also used, as a critical lens to look at teachers’ practices that have been disrupted by the increasing digitalization of schools. In our data collection, we adopted a user-centered design methodology, supported by ethnomethodology and co-design workshops in situ and online. According to our data teachers are experiencing pressure with respect to three main aspects: educating themselves and their students about GDPR and use of Social Media (SoMe) platforms, which are designed to facilitate data sharing on a global scale; how to handle students’ data avoiding leaks or potential conflicts, and finally the expansion of the boundaries of the school ecology. This last aspect appears of critical relevance, as the increasing digitalization of education and the spread use of SoMe platforms, has compromised the locality of the school as an ecology, leading to increasing uncertainty and lack of overview on the actions undertaken by its actors.Publicação Acesso Aberto Special Issue Information2023-01 - Fernandes, Cristina; Durão, Natércia; Moreira, Fernando; Lobo, Carla Azevedo; Santos-Pereira, CarlaDear Colleagues, Sustainability generally addresses three fundamental pillars: environmental and ecological, economic, and social. It is a concept related to the conservation or maintenance of a scenario in the long term to deal well with possible threats. The notion of sustainability emerged supported by the clear understanding that natural resources are limited and finite. In this understanding, sustainable development is a development that meets the needs of the present without compromising the ability of future generations to meet their own needs. [...]Publicação Acesso Aberto Big data analytics on patents for innovation public policies2021 - Sousa, Maria José; Jamil, George; Walter, Cicero Eduardo; Au-Yong-Oliveira, Manuel; Moreira, FernandoThis study seeks to answer the following research question: “What factors can explain the number of patent filing requests made by residents in Brazil at patent offices in Brazil, the United States, Europe, and triadic patent families?”. The methods used in this research are quantitative, using big data from private and public investments in Science and Technology, and about patent deposit numbers in Brazil from 2000 to 2017. A model of linear regression was performed and explains how these investments in Science and Technology influence patent deposit numbers. The results of this research study point towards the importance of universities, up and beyond the traditional training and education aspect of university activity. The importance of public and private innovation investments is also shown to be important. This study shows that the patent registrations in the different regions under analysis are affected by different factors. There is thus no single formula towards the creation of innovation output and governments would do well to continue to invest in higher education while also investing in public research and development activities. Additionally, and not least important, private entities should be continually encouraged to make innovation investments and favourable government policies need to thus exist for this to happen. Finally, the low numbers regarding patent filings in Brazil may be linked to institutional deficiencies in the country. Patent breaches may be difficult to punish, and the judicial system may be slow and untrustworthy, compared to the United States and to Europe—leading to diminished patent registrations in Brazil. A set of implications and recommendations for policy derived from this study and will be strategic for policymakers.Publicação Acesso Aberto The state of mobile learning supported by gamification and augmented reality in higher education institutions across three continents2020-01 - Annamalai, Nagaletchimee; Moreira, Fernando; Ferreira, Maria João; Durão, Natércia; Santos-Pereira, CarlaThe pervasive digitization is now a reality for organizations and society at large. In the last decade, for example, smartphones have been gradually transforming their scope from just voice communications providers to powerful media and computing devices. This transformation has led to a growth in business initiatives, namely in the services provision throughmobile applications. In this context, higher education asanorganizationandpartofsociety is compelled to change its operant mode in general and in particular in the teaching‐learning process making it more digital and at the same time more motivating for students. The aim of this study is to investigate the perception that higher education professors in the area of technology, across Southern Europe, South America, and Asia have about the use of mobile technologies such as gamification and augmented reality and how they can be used to promote student’sengagementinsideandoutsideoftheclassroom.Publicação Acesso Aberto Evolution and use of mobile devices in higher education: A case study in Portuguese Higher Education Institutions between 2009/2010 and 2014/20152017 - Ferreira, Maria João; Durão, Natércia; Santos-Pereira, Carla; Moreira, FernandoMobile devices’ popularity, particularly tablets and smartphones, has increased over the last years as a result of their versatility and multifunctionality. That consequently led to a wide daily use by everyone and especially among young people. Since 2010 the sales market for mobile devices has not stopped growing. This is justified by the fact that these devices present many advantages, namely usability, portability, versatility, adaptability and an ability to customize individual experiences. In the context of the teachinglearning process, mobile devices allow overcoming the temporal and physical boundaries of the classroom, since information is omnipresent and no longer limited to a specific time and place for learning, thus promoting the mLearning. In this way it is important to analyze the use of mLearning, particularly the acceptance rate and uses of mobile technologies devices in higher education Portuguese institutions. In order to answering this issue, this paper analyzes the evolution and trends in the use of mobile technologies in higher education institutions in Portugal (North region) between 2009/2010 and 2014/2015.Publicação Acesso Aberto The role of AI and automation on the future of jobs and the opportunity to change society2019-03 - Au-Yong-Oliveira, Manuel; Canastro, Diogo; Oliveira, Joana; Tomás, João; Amorim, Sofia; Moreira, FernandoIn today’s world, technology is an indispensable part of our daily life. More and more products are produced to satisfy the needs of a growing population and the Internet is creating new services every day. However, to be able to keep up with the growing demand, new technologies needed to be invented to increase the pace of production and to lower costs. Automating tasks was the solution and for many years machines did repetitive tasks, replaced people and created new and better jobs to substitute the old ones. Nowadays automation is reaching incredible levels and it is not creating enough jobs to replace the old ones. Will unemployment increase in the upcoming years or will humanity be able to adapt to a different job market? Our study focuses on the types of unemployment caused by automation and on the possible solutions that society needs to implement. The research also points out how people from different social classes face the changing job market and how all can benefit from it. A new form of governance of society may be needed, in view of previous failed forms including fascism, communism, and, more recently, liberalism. In the future there will be fewer and fewer jobs that cannot be replaced by a robot. With this, the probability of mass unemployment is very high. An ideology promoting a Universal Basic Income could be a solution to combat the massive unemployment that automation may cause in the future, especially in medium-skilled jobs.Publicação Acesso Aberto Enhancing reliable and energy-efficient UAV communications with RIS and deep reinforcement learning2025-08-29 - Ahmad, Wasim; Islam, Umar; Abdulkadhem, Abdulkadhem A.; Shah, Babar; Moreira, Fernando; Abbas, AliThe rapid growth in wireless communication demands has led to a surge in research on technologies capable of enhancing communication reliability, coverage, and energy efficiency. Among these, uncrewed aerial vehicles (UAV) and reconfigurable intelligent surfaces (RIS) have emerged as promising solutions. Prior research on using deep reinforcement learning (DRL) to integrate RIS with UAV concentrated on enhancing signal quality and coverage, but it ignored the challenges caused by electromagnetic interference (EMI). This article introduces a novel framework addressing the challenges posed by EMI from Gallium nitride (GaN) power amplifiers in RIS-assisted UAV communication systems. By integrating DRL with quadrature phase shift keying (QPSK) modulation, the proposed system dynamically optimizes UAV deployment and RIS configurations in real-time, mitigating EMI effects, improving signal-to-interference-plus-noise ratio (SINR), and enhancing energy efficiency. The framework demonstrates superior performance, with an SINR improvement of up to 6.5 dB in interference-prone environments, while achieving a 38% increase in energy efficiency compared to baseline models. Additionally, the system significantly reduces EMI impact, with a mitigation rate of over 70%, and extends coverage area by 35%. The integration of QPSK and DRL allows for real-time decision-making that balances communication quality and energy consumption. These results show the system’s potential to outperform traditional methods, particularly in dynamic and challenging environments such as urban, disaster recovery, and remote settings.Publicação Acesso Aberto DualRep: Knowledge Graph Completion by Utilizing Dual Representation of Relational Paths and Tail Node Density Insights2024-11-18 - Gul, Haji; Al-Obeidat, Feras; Amin, Adnan; Wasim, Muhammad; Moreira, FernandoKnowledge graphs (KGs) possess a vital role in enhancing the semantic comprehension of extensive datasets across many fields. It facilitate activities like recommendation systems, semantic searching, and intelligent data mining. However, lacking information can sometimes limit the usefulness of knowledge graphs (KGs), as the lack of relationships between entities could severely limit their practical application. Most existing approaches for KG completion primarily concentrate on embedding-based methods or just use relational paths, neglecting the valuable structural information offered by node density. This research presents an approach that effectively combines relational paths and the density features of tail nodes to enhance the accuracy of predicting relationships that are missing in knowledge graphs. Our method combines the sequential relational context represented by paths with the structural prominence indicated by node density, allowing for a dual view on possible entity connections. We validate the effectiveness of our technique by conducting comprehensive tests on many benchmark datasets, revealing substantial enhancements compared to conventional approaches. The Dual-Rep model, which incorporates relational paths and node density features, has continuously shown improved performance across several metrics, such as Mean Reciprocal Rank (MRR), Hit at 1 (Hit@1), and Hit at 3 (Hit@3). The DualRep model achieved a mean reciprocal rank (MRR) of 90.80. Additionally, it achieved a hit rate of 87.39 at rank 1 (Hit@1) and a hit rate of 91.18.Publicação Acesso Aberto Technology usage as a way to increase safety and security in different geographies: Testimonials on the use of technology in Rio de Janeiro, Brazil2018 - Au-Yong-Oliveira, Manuel; Martins, José; Branco, Frederico; Gonçalves, Ramiro; Moreira, FernandoThis study follows an interpretivist approach and showcases five testimonials of technology usage in everyday life, in Rio de Janeiro, Brazil; the research also brings forward the perspectives of 31 other Brazilian citizens. The informants are Brazilian Master's level students who were on an exchange program to Portugal, at a major Portuguese university. Brazil, and in particular Rio de Janeiro, the focus of this study, are seen to have talented people and to be also open to technology - on the developing side as well as on the user side. Trust issues still exist - concerning e-commerce - and may indeed be pervasive in society. Brazil is currently undergoing a profound social and economic crisis, which it is trying to recover from. Indeed, the general lack of safety and security felt in Rio de Janeiro may even be a reason for the popularity of home and work deliveries - so that citizens will not have to travel - with travel constituting an additional risk which many may prefer to avoid. Thus, technology (a diverse set of apps) may be serving an additional purpose - that of ensuring security in daily life in Brazil.Publicação Acesso Aberto Modelo Blended Mobile Learning orientado ao contexto aplicado ao ensino de redes de computadores.2011 - Ferreira, Maria João; Moreira, Fernando
