Perturbações do humor: depressão e suicídio
Publication . Silva, Celso Filipe Boto
O documento aborda a depressão como uma perturbação do humor sistémica, neurobiológica e potencialmente fatal, desmitificando a ideia de que se trata de uma mera fraqueza de caráter ou falta de força de vontade. O texto enquadra a depressão no panorama global da saúde mental (destacando dados da OMS e o impacto da pandemia de COVID-19) e apresenta os critérios de diagnóstico (com base na CID-11 e DSM-V), a etiologia multifatorial e a diferenciação entre a tristeza normal e a tristeza patológica. São igualmente descritos os múltiplos sintomas que afetam as esferas afetiva, cognitiva, comportamental, do pensamento e fisiológica.
No que concerne ao suicídio, o documento desconstrói mitos e aborda os fatores de risco, sublinhando a importância da avaliação sistemática do risco.
From the atelier populaire to artivism. Situationist strategies reimagined
Publication . Cavalcanti, Maria Cristina; Tavares, Mirian; Arantes, Priscila Almeida Cunha
The following paper examines the progression of artivism by tracing the visual strategies employed by the Atelier Populaire during the May’ 68 protests, tactics influenced by the Situationist International, and investigates their relationship to contemporary artivist practices, particularly in the field of digital media art. The article focuses on the legacy of these strategies and explores the trajectories of Richard Hambleton, Blek le Rat and Banksy, emphasizing their contributions to social and political discourse through art. It highlights the prioritization of message over aesthetics, the democratization of public space, unsigned drawings, stencils, and other low-cost techniques, direct as well as symbolic imagery. The study concludes by examining the current relevance of artivism across various platforms, including digital media, and investigates how these new mediums reshape and amplify the scope and modalities of artivism in the contemporary context.
Memory, montage, and counter-narratives: a digital media installation
Publication . Cavalcanti, Maria Cristina
This work presents the multimedia installation [Des]montagem, which articulates memory, history, and aesthetics through the appropriation and recontextualisation of archival materials related to repression during the Brazilian civil-military dictatorship (1964–1985). Rooted in concepts of memory and montage, the installation challenges the unequal formation of memory and the influence of dominant narratives in official history, while aiming to validate silenced voices. Drawing from the works of Walter Benjamin and Aby Warburg, [Des]montagem utilizes visual, auditory, and interactive components to establish a realm for confronting and contemplating the past and the present. The installation also includes a virtual version that broadens public access, enabling new forms of engagement. The project highlights the potential of digital art to politicise memory and foster critical thinking, showing that we are active agents in the construction of our own history.
Digital media art and archaeologies of the invisible: the case of mãe soberana in dialogue with Zielinski
Publication . Mendonça Pintassilgo, Andreia Isabel; Soares, Ana Isabel; Guerriero, Maria
Digital media art, an artistic expression emerging from contemporary technological culture, signals a revolution in how cultural experiences are transmitted and lived. In this context, the case “Mãe Soberana – Our Lady of Piety,” in Loulé, exemplifies the convergence between art, technology, and intangible heritage. Using tools such as augmented reality, video art, QR codes, and artificial intelligence (AI), the project proposes an interactive and participatory reinterpretation of Marian devotion, integrating memory, faith, and innovation. Inspired by Zielinski’s Media Archaeology, the study adopts a non-linear reading of technological history and explores relationships between the visible and the invisible, the sacred and the digital. The methodology combines an a/r/tographic, qualitative, and participatory approach, involving the local community in building digital narratives and safeguarding intangible cultural heritage. This proposal resonates directly with Siegfried Zielinski’s Media Archaeology diagram by adopting a non-linear reading of media history and valuing the multiplicity of trajectories, layers, and technologies. Devotion to Mãe Soberana is reinterpreted as a hybrid territory of artistic expression, where digital technologies are not merely mediation tools but devices for creation, evocation, and participation. The research proposes an archaeology of the invisible, revealing symbolic and affective layers of the devotion through technological mediation. It thus contributes to reflection on the ethical and critical integration of digital art in the valorization of intangible cultural heritage.
Reported declines of the grooved carpet-shell clam (Ruditapes decussatus) across southwestern Europe and the Mediterranean: insights from expert knowledge

The grooved carpet-shell clam (Ruditapes decussatus) is a native clam species that inhabits estuaries, lagoons, and coastal flats along the Mediterranean Sea and the northeast Atlantic. This highly prized bivalve is an ecosystem engineer that provides major ecological functions, including water filtration and sediment bioturbation. A decline in production has recently been observed in several areas of southwestern European and the Mediterranean region; however, data documenting this phenomenon remain scarce and are largely unpublished. To address this knowledge gap, we conducted a study based on official statistics, the expertise of 24 marine ecosystem experts from eight countries covering 17 coastal sites, and a preliminary literature map. This approach enabled the development of an expert-informed regional perspective on the reported declines of R. decussatus, as well as a synthesis of the regulatory measures and restoration actions implemented across the study area. The findings indicate a sharp decline in both production ( 32 to 100%) and stocks (≈ 80%) over the past two decades. The onset of the decline varied among sites, occurring between 2003 and 2024. According to the participating experts, the main suspected drivers of the decline were disease, overfishing, competition with alien species, and climate change. The most common regulatory measures were minimum conservation reference sizes, closed fishing seasons, and licenses. Only a few restoration projects were identified, focusing on restocking through seeding, the collection of natural broodstock, harvesting natural spat or substrate modification. This study provides a preliminary overview of the seemingly widespread decline of R. decussatus across the southwestern European and Mediterranean region and highlights the need for coordinated research to elucidate the causes of this reported decline, as well as for restoration actions to support the recovery of this native species.
