The ubiquitous co-contamination of traditional and novel brominated flame retardants (TBFRs and NBFRs) in anaerobic environments necessitates a comprehensive understanding of their combined environmental fate. This study investigated the anaerobic biotransformation of BDE 99 (a legacy aromatic TBFR) and β-TBCO (a cycloaliphatic NBFR) using a Dehalogenimonas-containing mixed culture (QY2-S1) under single- and co-exposure conditions. In a single-exposure system, QY2-S1 achieved efficient transformation of both substrates, with the observed first-order kinetic constants (k_obs) of 1.31 ± 0.09 d⁻¹ and 2.35 ± 0.13 d⁻¹ for BDE 99 and β-TBCO, respectively. However, the corresponding k_obs values decreased by approximately 3- to 5-fold in a co-exposure system, demonstrating pronounced reciprocal kinetic inhibition. Notably, while culture QY2-S1 maintained a unique ortho-regioselectivity for BDE 99, its stepwise debromination was truncated at the tetra-BDE stage during co-exposure. Absolute quantitative 16S rRNA sequencing identified Dehalogenimonas as the sole organohalide-respiring bacterium, with its abundance initially increasing in tandem with substrate transformation. However, the dehalogenation-coupled cell growth of Dehalogenimonas was significantly modulated by substrate type and combination, with its absolute biomass following the order of: single β-TBCO > co-exposure > single BDE 99. Collectively, these results suggest that the reciprocal kinetic inhibition and the truncation of the BDE 99 debromination pathway under co-exposure are collectively driven by the suppressed growth and substrate preference of Dehalogenimonas. This study provides critical insights for predicting ecological risks and developing bioremediation strategies for co-occurring BFRs in real-world scenarios. Full article

This qualitative media-archaeology study examines how digital video compression can reshape viewer perception of a legacy television image. A low-resolution online image from the 1976 The Mary Tyler Moore Show is compared with the corresponding image from a commercial DVD. In the compressed 360p online version, Moore’s upper torso appears briefly overexposed during a bubble-bath scene—an interpretation often described as a wardrobe malfunction. However, the higher-resolution DVD clearly shows that Moore maintained broadcast standards by wearing a protective undergarment that became visually erased in the compressed media. This divergence serves as a result of a natural experiment, demonstrating how low-resolution encoding of an image produces edge smoothing, tonal blending, and dissolution of material boundaries. These transformations support an inductive interpretation of materiality collapse, a compression artifact in which garments, skin, and shadows lose visual distinctiveness—creating an image of Mary Tyler Moore perceptually similar to a classical nude sculpture such as the Venus de Milo. Contextual evidence from Moore’s autobiography further clarifies production norms that shaped the bubble-bath scene and contributed to insufficient foam coverage. The findings show how compressed digital video can generate culturally consequential misperceptions, underscoring the need to scrutinize online compressed images posted as material evidence.

Current models of dementia care often perpetuate the legacies of colonization, which highlights the need for a culturally congruent approach. This research describes the necessary components to co-develop a freely available Indigenous-centered dementia model of care in partnership with Indigenous individuals living with dementia, their families, and communities. To prioritize ethical and decolonial research approaches, sequential focus groups were used alongside Keeoukaywin (The Visiting Way)—an Indigenous methodology deeply rooted in Métis and Cree ways of knowing—guided by a group of advisors and Elders. The data were co-analyzed using reflexive thematic analysis guided by Indigenous principles. Three themes were generated: Indigenization, Personalization, and the Intersection of Challenges and Innovations, to illustrate how dementia care can be operationalized and adapted to various cultural and care contexts. This research offers a foundation for developing dementia care that truly aligns with Indigenous ways of doing. Full article

This article analyses pneumatic (inflatable) objects as used in the work of four contemporary European artists from diverse disciplinary backgrounds: choreographers Adrienne Hart and Gabriella Engdahl, and visual artists Michael Shaw and Bambí Benkö. Deployed across deconsecrated churches, swimming pools, theatres, galleries and streets, these works demonstrate a broad spectrum of engagement with inflatables, ranging from formalist to existential, social and political-activist purposes—all implicating choreography in an expanded sense. Informed by theories from the visual arts, dance studies and sociology, as well as interviews with the artists themselves, the analysis adopts a multi-methodological approach attuned to this diversity. Overarching concerns about spectatorship, site and materiality centre on how inflatables’ precarious properties—porous seams requiring continual reinflation—engender playful instability and encourage interaction with audiences. Proposing ‘whimsy’ as a critical lens, the essay reimagines contemporary inflatables as cultural-choreographic objects that question disciplinary boundaries. The artists’ practices both extend a 1960s legacy of pneumatic experiments and redirect their utopian-critical impulses toward twenty-first-century issues. Full article

Environmental knowledge encoded in Bahnar, an Indigenous language of Vietnam, is vital to the Bahnar community and contributes to broader understandings of biodiversity, climate resilience, and sustainable lifeways. We describe a collaborative approach to documenting Bahnar that integrates computational methods with ethnographic, lexicographic, and linguistic fieldwork. Because Bahnar knowledge is transmitted almost entirely through oral tradition rather than writing, effective documentation cannot rely solely on extractive corpus-based or NLP tools. Although three legacy bilingual Bahnar dictionaries exist, they are partially obsolete, uneven in coverage, and largely inaccessible to the community itself. Our corpus analysis of the Bahnar environmental vocabulary, complemented by intensive community-based fieldwork, reveals semantic patterns that closely link environmental knowledge with Bahnar lifeways, subsistence practices, and material culture. These patterns, we argue, are language-specific and may not emerge from analyses of environmental lexicons in languages such as English or Vietnamese. Bahnar semantic categories attribute aesthetic, medicinal, mythological, and spiritual agency to animals, plants, and landscapes, contrasting with classificatory frameworks common in post-industrial societies that emphasize biophysical, scientific, or economic properties. We propose that community-centered digital lexicography can strengthen Bahnar language vitality, enhance local access to cultural knowledge, and simultaneously advance comparative linguistic and environmental research.

This paper examines how conversational daily deep dive news podcasts build journalistic authority and legitimacy through what we call the “journalist-as-guest” (JAG) format. Applying a deep analytical listening methodology that honors the aurality of the medium and positions listening as a core analytical method, we analyzed eight daily deep dive news podcasts from Canada and Australia, attending to how sonic elements interact with conversational performance to produce podcasting’s characteristic intimacy and parasocial listener bonds that support authority and legitimacy claims for journalism. Our findings expand on our previous identification of the JAG format as a key element of explanatory-type daily deep dive podcasts. Here, we reveal how it operates through three key mechanisms: recurring self-referential speech that reinforces journalistic cultural belonging; intentional unpacking of the reporting process to reveal behind-the-scenes work; and the careful construction of journalists as subject-matter experts. Together, these mechanisms transform performative conversation into metajournalism, creating a space in which journalistic expertise is displayed and validated through colleague-to-colleague dialogue. We term this dynamic “intimate authority.” We argue that the JAG format capitalizes on podcasting’s affordances for intimacy, parasociality, and extended metajournalistic conversation to invite audiences into the news-making process while positioning journalists as credible experts and sense-makers. In doing so, it functions as a mechanism for establishing authority and legitimacy claims in digital media environments. As daily news podcasting becomes increasingly central to remediation efforts aimed at restoring trust in journalism, both legacy and independent news podcasters appear to be counting on the JAG format as a strategic response to concurrent crises of news avoidance and relevance.

Notwithstanding the cruciality of the decolonisation project in decentring African perspectives and experiences in education, very few studies have explored the extent to which the Fallist Movements in South Africa have presented foundational pathways for academic staff to negate colonial legacies and recentre African thought systems. Through a systematic literature review of research from the public domain, this study couched within the decolonial lens explored university students’ concerns, embedded in the Fallist Movements in South Africa, and how academic staff could draw lessons from student actions to decolonise education. After screening the initial 65 entries, based on the exclusion and inclusion criteria, 19 research studies published between 2015 and 2025 were retained for analysis. Findings reveal three recurring concerns: disrupting positionality in colonial categories of universities, reasserting their Being, and agitating for a decolonised curriculum, of which these embodied the spirit of students’ resilience against cultural colonisation, epistemic erasure, and economic exclusion. Building on these findings, the paper argues that such resilience from students enlightens the strategies academic staff could learn to transform the decolonisation project into reality. Implications for the academic community in South Africa and comparable contexts are proposed to resuscitate the unfinished business of decolonising education. Full article

Although apartheid ended in 1994, its legacy continues to shape South Africa’s higher education system, reinforcing disparities in access, funding, and representation. This study aims to critically examine how apartheid diplomacy has influenced higher education and asks: how do its strategies continue to shape academic practices, institutional relationships, and systemic inequalities in post-apartheid South Africa? It conceptualises apartheid diplomacy as the use of education to entrench racial hierarchies, reproduce class domination, and suppress indigenous knowledge. Grounded in Marxist and Weberian class theories and Crenshaw’s intersectionality framework, the analysis traces how apartheid-era policies institutionalised systemic inequalities and how these legacies persist within institutions. A scoping review was conducted using five databases (EMBASE, APA PsycINFO, Cochrane Library, CINAHL, and Scopus) between January 2007 and April 2025, guided by PRISMA ScR and Arksey and O’Malley’s six-stage framework. Of 75 articles retrieved, 15 met the inclusion criteria. Findings reveal that apartheid diplomacy shaped academic governance, resource distribution, and knowledge production, leaving enduring inequities despite ongoing reforms. Transformation efforts, including financial aid schemes, equity policies, and curriculum debates, have achieved progress but remain constrained by structural, cultural, and intersectional barriers. The study underscores that achieving lasting equity requires continuous policy interventions, inclusive leadership, and curriculum decolonisation, alongside advocacy and interdisciplinary research. It reframes higher education as a diplomatic arena where equity and epistemic justice are negotiated, offering an original lens for understanding and dismantling apartheid’s enduring influence on South African academia.

The article illustrates the digital documentation workflow adopted to effectively use digital survey outcomes in supporting the knowledge and conservation of built heritage. This study was developed as part of the Project of Significant National Interest (PRIN), titled “KNOW.it Transition in Digital Age: KNOWing our background to refine our future”. The research focuses on the cities of Jaú and São Carlos, applying a rigorous methodology that combines archival research, photogrammetry, laser scanning, and 3D modelling. This approach is used to identify, analyse, and digitally reconstruct Italian-influenced eclectic architecture from the late 19th to early 20th century. The initiative supports both scholarly research and public dissemination through a digital platform that will host interactive maps, historical documents, 2D drawings and 3D models. By linking academic research with diasporic memory, KNOW.it highlights how digital tools can preserve and reactivate cultural legacies, fostering transnational heritage dialogue. The project’s use of social media further engages local communities in a participatory process, enriching its digital archive with crowdsourced memories and documents. The project opens up new possibilities for international cooperation, digital heritage practices, and the study of architectural migrations, showing how critically informed digital tools can recontextualise and enhance dispersed historical knowledge.

The San Juan Islands are one of the few places where native temperate grasslands are found in western Washington State. These ecosystems are important reservoirs of biodiversity and sources of ecosystem services, support many rare and endemic species, and have profound cultural significance to the Coast Salish peoples. These ecologically and culturally valuable ecosystems have become scarce due to the combined pressures of changes in land use, the introduction of non-native invasive species, and the exclusion of fire from the landscape. A lack of historical context and ecological baseline knowledge has made it impossible to fully understand the long-term trends in the extent and distribution of this ecosystem. To address this knowledge gap, we used historical land cover data and multispectral imagery to create a high-resolution, spatially explicit database of grassland extent on the San Juan Islands at multiple time periods since the early years of Euro-American colonization. Our spatial analysis of these data revealed significant decreases in grassland extent between time periods, with an overall 77% net decrease in the extent of non-agricultural grasslands and a loss of 93% of the area of persistent, old-growth grasslands since 1890 across the region. These changes are primarily a result of conversion to agriculture and conifer encroachment or succession to forest. The spatial data and analyses created in this study help to develop the historical baseline of native temperate grasslands on the San Juan Islands, adding to our understanding of the lingering legacy that changes in land use have had on this ecosystem, with the potential to aid in the development of effective conservation and restoration practices.

This Perspective is dedicated to the memory of Professor Joseph Mark (Joe) Gani (1924–2016) and Professor Christopher Charles (Chris) Heyde (1939–2008), two scholars whose intellectual leadership profoundly shaped applied probability, mathematical statistics, and their interface with finance, insurance, and risk management. Their contributions extend beyond specific technical results to the development of research cultures grounded in probabilistic rigor, empirical relevance, and methodological transparency. We emphasize three enduring themes central to modern quantitative risk analysis. First, the systematic incorporation of heavy-tailed and non-Gaussian features in stochastic modeling, reflecting persistent empirical deviations from classical Gaussian assumptions in financial data. Second, the development of stochastic and time-series methodologies capable of handling dependence structures, including conditional heteroskedasticity and long-range dependence. Third, the principled integration of probabilistic modeling with data-driven and machine learning approaches, ensuring predictive performance is accompanied by interpretability and robustness. We situate these contributions within contemporary challenges in financial risk management, including systemic risk, environmental, social and governance (ESG) considerations, and climate finance. In particular, climate-related financial risks arise from both physical impacts (such as extreme weather events and long-term environmental change) and transition dynamics associated with the shift toward a low-carbon economy (including policy, technological, and market adjustments). These sources of risk introduce additional forms of dependence, nonlinearity, and model uncertainty, particularly in high-dimensional, data-rich settings. This Perspective highlights a forward-looking research agenda that preserves the foundational principles of applied probability while adapting them to modern financial systems characterized by real-time information flows and evolving risk structures. This legacy continues to shape how financial risk is modeled, measured, and understood in increasingly complex and interconnected environments. Full article

This study examines the persistence, change, and discontinuity of human settlements in the northern Stig Plain along the Danube in Serbia. It examines how natural conditions, together with historical events and the strategic imperatives of specific periods, have shaped the establishment, development, decline, and abandonment of settlements in this landscape, as well as their change and transformation. Particular attention is given to the Roman city of Viminacium, now largely buried beneath fertile farmland and affected by mining activity. The research integrates theoretical perspectives on landscape, human–environment relations, and processes of discontinuity and change with insights into Roman urban planning and overall settlement dynamics, contextualised through the environmental and historical development of the landscape. It considers why Viminacium remained the only major urban centre in the plain and why no later settlement developed directly above it, reexamining whether this absence can be understood as a form of landscape discontinuity. The findings emphasise the strong influence of natural factors, while suggesting that the urban potential of the fertile Stig Plain could only be fully realised in the Roman period, through the establishment of a legionary fortress supported by advanced technology and organised labour, and guided by strategic objectives. From a heritage perspective, the study also examines the definition of landscape boundaries, highlighting Viminacium’s legacy as an integrative element that brings together remains from multiple periods into a unique and evolving cultural landscape worthy of preservation, though one that faces ongoing challenges in sustainable management.

This study investigates women’s textile knowledge in Portugal as a fundamental element of cultural heritage, situating it within domestic, social, and industrial contexts, with a particular focus on Guimarães. Drawing on a multidisciplinary approach grounded in historical and documentary evidence, it analyses how female expertise in spinning, weaving, embroidery, and lacemaking contributed to the evolution of textile practices from the fifteenth century to the present day. The findings indicate that this knowledge was pivotal to the transformation of domestic textile activities into an emerging industrial sector, shaping both production methods and cultural identity. The study concludes that recognising the historical importance of women’s textile labour is essential for understanding the development of the Portuguese industry. Furthermore, this research underscores the urgency of preserving, transmitting, and legitimising the intangible cultural heritage associated with women’s textile knowledge. It argues that integrating this legacy into contemporary creative and industrial practices can foster cultural sustainability and unlock new possibilities for future innovation, ensuring that this ancestral expertise remains a living pillar of regional identity.

This article examines the ethical and aesthetic stakes of cultural borrowing in fashion through the case of Yves Saint Laurent’s sustained engagement with Moroccan visual and material traditions. Drawing on postcolonial theory, fashion studies, and aesthetic philosophy and supported by visual analysis and qualitative research, this study interrogates the tension between cultural appreciation and appropriation that structures Saint Laurent’s legacy. His designs amplified global visibility for Moroccan craftsmanship, yet this visibility was mediated through Western systems of authorship that privileged the couturier while obscuring the cultural, spiritual, and artisanal labor underpinning the motifs he reinterpreted. Saint Laurent’s own positionality, born within the colonial milieu of French Algeria, further complicates this dynamic, enabling both cultural intimacy and the exercise of hierarchical distance from the traditions he transformed for Parisian haute couture. This discussion also requires acknowledging that Moroccan cultural heritage, shaped by the intertwined influences of Amazigh, Arab, Islamic, and Jewish traditions, embodies religious meanings that extend beyond the purely aesthetic. By considering the religious, symbolic, and communal values embedded within Moroccan aesthetic forms, this article foregrounds the ethical dilemmas that arise when culturally and spiritually situated practices are reframed within Western fashion. This study ultimately contends that acts of borrowing can serve both as homage and erasure, suggesting that the relationship between appropriation and appreciation is better understood as a flexible spectrum rather than a rigid binary.

Sacred natural sites are often considered potential refugia for biodiversity in human-dominated landscapes, but their effects can be confounded by present-day habitat structure. We tested whether extant Cistercian monasteries in western Poland influence breeding-bird assemblages at two spatial scales by conducting standardized 5 min point counts during two visits at 234 stations across 23 plots and comparing Cistercian plots with environmentally matched Control and Post-Cistercian plots. We recorded 133 breeding-bird species, numerically dominated by widespread farmland and synanthropic taxa. Neither plot category nor station placement within versus outside monastery grounds explained variation in Shannon diversity or rarefied species richness. In contrast, both diversity metrics increased with contemporary landscape complexity, especially along gradients from arable land toward grasslands and urban habitats and with increasing heterogeneous agriculture, while community composition was significantly associated with current landcover structure. These findings indicate that present-day habitat structure, rather than monastic legacy, is the main driver of breeding-bird diversity in this system. Conservation and land-use policy in agricultural regions should therefore prioritize the maintenance and restoration of heterogeneous landscapes, including mosaics of semi-natural habitat elements.
