    Promoting critical thought through university curriculum decolonising: Insights from a semi-systematic literature review
    (2025) Muhr, T.; CrithinkNet – Rede Portuguesa de Pensamento Crítico
    Since the 2015/2016 #RhodesMustFall and #FeesMustFall student protests in South Africa, higher education decolonisation has become a global movement and rapidly growing field of study. In this, university curriculum decolonising (UCD) assumes centrality, as one (and only one) strategic moment in intersectional (class, gender, race) struggles for social and epistemic justice, inclusiveness and liberation, for decolonising academia, knowledge and society at large. Framed by critical sociology of education, this presentation reports findings from my semi-systematic review of global UCD literature, conducted in 2023/2024 as part of a larger FCT-funded research project. The Electronic Library Online (SciELO), Scopus and Web of Science databases were searched using an English/Portuguese search string. This systematic search yielded 463 unique journal articles and book chapters published up to 2022 inclusive and was complemented by purposive search. While universities worldwide engage with UCD, no evidence of visible engagement with UCD in Portugal’s university sector emerged. This does not necessarily mean non-engagement. However, this finding is surprising considering Portugal’s coloniser history and ongoing neo-colonial engagement via, for example, the Community of Portuguese Language Countries (CPLP) as a pool for international student recruitment. Key findings generated through thematic analysis will be reported in three categories: (i) theoretico-conceptual framings of UCD (‘decolonisation’; ‘decoloniality’; ‘coloniality of power’); (ii) the politics of UCD (‘add-on’, ‘institutional-transformist’ and ‘systemic’ approaches); and (iii) methodical challenges in decolonial university curriculum analysis (quantitative proxy indicators vs qualitative thematic analysis). On this basis, this presentation speaks to the need for engaging with UCD in Portugal, with the explicit aims of conscientising and provoking critical thought and decolonial action within Portuguese higher education, and beyond.

    Dr. Strange, are we experiencing the same?: Perceptions of the metaverse among gamers, by gender
    (2025) Cruz, M.; Oliveira, A.; Lorenz, Pascal
    On the wave of a great digital revolution, virtual reality enables immer- sive experience in cyberspace via various devices, gliding virtual worlds in a dynamic multiverse. To what extent can a film focused on the multiverse be linked to the perceptions of the Metaverse among Portuguese adults? And, more: Are there significant differences between men’s and Women’s perceptions? In this context, we aim to verify the representations of the Metaverse of each gender and verify the importance of a film (related to the Metaverse and the multiverse) on these representations. Embracing technological advancements is crucial for soci- etal progress, with films playing a significant role in conveying complex concepts and fostering acceptance through immersive storytelling and virtual reality. Fic- tional narratives, especially those enhanced by technology, can shape attitudes and beliefs, demonstrating the transformative potential of virtual reality and fiction. This study emphasises the relevance of gamers in understanding and engaging with the concepts of Metaverse and multiverse.

    China civil air traffic management efficiency improvement: Based on the view of four dimensional trajectory operation concept
    (2026-09-15) Wang Qian; Pereira, Leandro F.; Shao Yunfei
    This study investigates the major challenges faced by China’s air traffic management system amid rapidly growing demand, constrained airspace resources, and persistent efficiency bottlenecks, and examines the natural evolution toward four dimensional (4D) Trajectory Based Operations. Drawing on international and domestic practices as well as recent technological advances, the study develops a comprehensive cost–benefit assessment framework that incorporates the full lifecycle economic, social, and environmental impacts of 4D operations. Using Monte Carlo simulations to test the sensitivity of key variables, the results demonstrate the feasibility of implementing 4D Trajectory Based Operations within China’s operational context. Meanwhile, the research establishes an evaluation indicator system covering operational effectiveness, organizational impacts, implementation challenges, and improvement needs. By integrating the Analytic Hierarchy Process (AHP) and a fuzzy comprehensive evaluation approach with surveys, interviews, and representative case studies, the study achieves a quantitative assessment of implementation outcomes and identifies critical bottlenecks. In addition, it proposes a phased and differentiated implementation pathway for 4D Trajectory Based Operations in China, together with coordinated optimization strategies across technology, organizational structures, and policy mechanisms. The findings provide theoretical support, quantitative evidence, and practical implementation guidance for the modernization of China’s air traffic management, offering meaningful solutions to capacity constraints, operational efficiency improvement, and enhanced system resilience.
