    O vazio urbano como equipamento cultural alternativo na cidade do futuro: O caso do Zénite em Lisboa
    (2025) Andrade, H. S.; Iannizzotto, L.; Lameira, Gisela; Rocha, Luciana
    Na cidade contemporânea, existem espaços abertos abandonados, sem função produtiva ou uso específico, que aguardam planos futuros, denominados vazios urbanos, terrenos vacantes ou baldios. Estes espaços, embora muitas vezes encarados como um problema ou como uma tabula rasa, reservam potencial social, ecológico e cultural para a cidade do futuro; de facto, são locais de apropriações informais, e até de espécies vegetais espontâneas. Além disso, devido às suas características, estes espaços oferecem oportunidades para projetos criativos temporários e efémeros, performances e instalações site-specific, experiências no campo da arte, arquitetura e design urbano, urbanismo tático e práticas espaciais críticas. Além disso, quando essas práticas temporárias e efémeras são integradas em estratégias e planos urbanísticos de grande escala e a longo prazo, tais projetos questionam e superam as contradições associadas às categorias tradicionais de efémero e permanente, de função fixa e flexibilidade, demonstrando o potencial para a criação de um novo tipo de equipamento público para a cidade do futuro, que combina práticas temporárias e estratégias a longo prazo, estruturas fixas e flexíveis para diferentes funções e atividades, posicionando-se como uma solução alternativa a processos de gentrificação. Este artigo pretende investigar as possibilidades, oportunidades e o potencial dos vazios urbanos como espaços para práticas criativas espaciais e críticas, propondo-se como um equipamento cultural urbano alternativo para a cidade do futuro, com os seus potenciais benefícios a partir de um caso de estudo. O artigo inclui, além de uma introdução teórica aos conceitos abordados, a descrição e análise de um estudo desse caso de estudo, o espetáculo Zénite (2024), encenado em Lisboa, no vale do Trancão, e uma leitura deste caso à luz das lentes teóricas apresentadas. Como discussão e conclusão, o artigo propõe refletir sobre o potencial destes espaços como equipamento cultural alternativo para práticas criativas temporárias, mas integradas em estratégias urbanas a longo prazo, flexíveis para vários usos e posicionados como solução contra a gentrificação dos espaços artísticos e culturais.

    Decolonising the university curriculum: Insights from a semi-systematic integrative literature review
    (2025) Muhr, T.
    Introduction: Since the 2015/2016 #RhodesMustFall and #FeesMustFall student protests in South Africa, higher education decolonisation has become a rapidly growing field of study and practice across disciplines worldwide. In this, university curriculum decolonising (UCD) assumes a central role, as one (and only one) strategic moment in these intersectional (especially class, gender, race) struggles for social and epistemic justice, inclusiveness and liberation, for decolonising the university, academia, and knowledge at large: on the one hand, the formal curriculum is political as it seemingly objectively establishes and legitimates what is deemed valid, recognised, relevant, authoritative knowledge; on the other hand, the curriculum is central in the university’s mission of social and epistemic reproduction (Adefila et al., 2022; GuzmánValenzuela, 2021; Morreira et al., 2020; Shahjahan et al., 2022; Stein & Andreotti, 2018; Veras et al., 2021). Objectives: Conducted in English and Portuguese between February 2023 and May 2024, this bilingual study seeks to contribute to improving linguistic diversity in higher education literature review (beyond the dominance of English) while extending previous reviews of higher education decolonisation in three distinct ways: theoretico-conceptually, by specifically mapping the emerging field of UCD through critical dialogue between globally shared referents and often overlooked particular contributions and contestations; methodologically, by proposing a pluri-scalar framework for critically analysing the politics of UCD; and practically, by culminating in methodical guidance for empirical decolonial university curriculum analysis. As a critical review, this also aims to conscientise and provoke decolonial action while informing future primary research, as a contribution to disrupting the reproduction of the structure of coloniality. Methodology: Within a critical sociology of education framework seeking social transformation, this study combines the semi-systematic approach to literature review (Snyder, 2019) with the integrative approach (Torraco, 2016). These approaches serve exploratory ends to generate an overview of a defined topic, to conceptually map a knowledge field, and to substantiate research agendas while stimulating further primary research (rather than, for instance, provide solutions to unresolved issues identified in the analysis) (Snyder, 2019; Torraco, 2016). The Scientific Electronic Library Online (SciELO), Scopus, and Web of Science Core Collection (WoS) databases were searched in February 2023 using an English/Portuguese search string. This systematic search yielded 463 unique journal articles and book chapters published up to 2022 inclusive and has been complemented by purposive search (e.g., checking references of references). Thematic analysis was used to identify patterns across the texts in accordance with the objectives of this review, presented as an analytic narrative that transcends mere descriptive mapping, synthesising and reporting, by critically generating new perspectives and frameworks on the topic (Braun & Clarke, 2021; Torraco, 2016, p. 404). Findings: In accordance with the objectives of the study, three key themes are discussed: (i) theoretico-conceptual framings of UCD, especially ‘decolonisation’, ‘decoloniality’, and ‘coloniality of power’, and conceptual contestations (e.g., post-colonial versus decolonial; the widely used notion of ‘epistemicide’; the complexities of learning:unlearning:relearning); (ii) the politics of UCD, including the ‘add-on’, ‘institutionaltransformist’ and ‘systemic’ approaches, and constraints to doing UCD at different scales (e.g., limits to individual academic agency and institutional/systemic cooption of UCD); and (iii) methodological challenges in empirical decolonial university curriculum analysis, regarding the selection of the case, data gathering/sampling, and analytical method and techniques (quantitative proxy indicators vs qualitative thematic analysis). Conclusions: Five agendas for future primary research generated from this analysis are elicited: (i) further development of decolonial university curriculum analysis methodology; (ii) how to decolonise oneself; (iii) how calls for UCD may impinge on liberal individual academic freedom; (iv) the relationship between UCD and academic quality; (v) universities’ responses to calls for UCD; (vi) countercooption strategies beyond isolated institution-based action.

    Gold- or silver-nanoparticle SERS platforms for plasma-based diagnostics and AI-driven analysis
    (2026) Elizur, G. L.; Canhoto, A.; Soares, G.; Ferreira, L. S.; Pereira, E.; Franco, R.
    Surface-enhanced Raman spectroscopy (SERS) has emerged as a highly promising analytical technique for disease diagnostics due to its exceptional sensitivity, molecular specificity, and ability to detect a broad range of biomarkers in complex biological matrices. This review provides a comprehensive overview of gold- and silver-nanoparticle-based SERS platforms for plasma disease diagnostics, covering advances in plasmonic nanostructures, biological sample analysis, biomarker detection, and AI-driven spectral data processing. Particular emphasis is placed on the application of SERS to clinically relevant biofluids, especially plasma, where the technique has demonstrated considerable potential for detecting diseases such as cancer, inflammatory disorders, and neurological conditions. The review also critically examines the major challenges currently limiting the clinical translation of SERS technologies. These include variability associated with substrate fabrication, matrix-induced signal fluctuations, limited interlaboratory reproducibility, and the lack of standardized protocols for spectral preprocessing and data analysis. Strategies proposed to address these issues are discussed, including comprehensive post-synthesis substrate characterization, optimization of biological sample preparation, advanced spectral preprocessing workflows, and the integration of machine learning and artificial intelligence algorithms to improve diagnostic robustness and reproducibility. Collectively, the advances summarized in this review indicate that SERS-based diagnostic technologies are rapidly progressing beyond proof-of-concept studies toward clinically applicable systems. Continued interdisciplinary collaboration and standardization efforts will be essential to bridge the remaining gap between experimental SERS methodologies and routine clinical implementation.
