Eco-anxiety refers to emotional and cognitive responses to environmental degradation and can manifest in both adaptive and maladaptive forms. This study aimed to identify distinct eco-anxiety profiles and examine their associations with resilience and vulnerability factors in a sample of 917 Portuguese-speaking adults. Latent profile analysis revealed five profiles: adaptive eco-anxiety, highly impaired maladaptive eco-anxiety, psychological distress independent of eco-anxiety, non-anxious/disengaged, and moderate I I have separated the addresses into different affiliations.have separated the addresses into different affiliations.eco-anxiety. These profiles differed significantly in psychological symptomatology, nature connectedness, pro-environmental attitudes, and prior exposure to cumulative social and environmental stressors. Higher-distress profiles were more likely among younger individuals, women, urban residents, unemployed participants, those without children, individuals with a prior psychiatric history, and those reporting direct exposure to drought. In contrast, stronger environmental identity and greater engagement with natural environments were associated with adaptive eco-anxiety, suggesting protective and resilience-promoting mechanisms. Overall, the findings highlight the multidimensional and heterogeneous nature of eco-anxiety and its complex relationship with psychological well-being and environmental engagement. Tailored interventions that promote adaptive coping, strengthen psychological resources, and facilitate access to natural environments may help mitigate maladaptive distress while supporting constructive environmental concern and action.

The sustainability of traditional vernacular dwelling heritage has become an important academic concern. This study takes the traditional vernacular dwellings of the Ancient City of Pingyao as its research object and develops a macro–meso–micro multi-scale analytical framework. Drawing on four dimensions—environment, layout, architecture, and culture—it systematically investigates the geographical environment, spatial pattern, and architectural forms of Pingyao’s traditional vernacular dwellings using GIS spatial analysis, UAV oblique photogrammetry, and 3D laser scanning technologies. On this basis, an AHP–FCE comprehensive evaluation model is introduced to assess their sustainability. The results indicate that the formation and persistence of these dwellings are closely associated with favourable natural environmental conditions, a clear and orderly spatial pattern, and well-structured courtyard and architectural forms. The comprehensive evaluation yields a score of F = 3.23, indicating a moderately high level of sustainability. The four criterion layers are ranked as follows: architecture, layout, environment, and culture. The key determinants are structural safety, material authenticity, spatial integrity, and the continuity of traditional character. By combining multi-scale analysis with comprehensive evaluation, this study aims to clarify the priority directions for the conservation of traditional vernacular dwelling heritage in the Ancient City of Pingyao, thereby providing a scientific basis for its sustainable development.

Zoological parks increasingly operate as sustainability-oriented institutions that integrate biodiversity conservation, environmental education, animal welfare, and community engagement. In parallel with these evolving roles, digital and interactive technologies have emerged as key instruments for supporting sustainable visitor engagement and conservation communication. This study provides a systematic review and conceptual mapping of the literature by combining a PRISMA-based systematic literature review with bibliometric co-word analysis. The bibliometric results reveal four thematic clusters: (1) mobile and visitor-oriented digital technologies, (2) immersive augmented reality (AR) or virtual reality (VR) based solutions, (3) animal–computer interaction and welfare-focused technologies, and (4) traditional conservation and education research. While digital technologies demonstrate measurable short-term effects on engagement, empathy, and knowledge retention, their long-term sustainability impact and systemic integration remain limited. To address this gap, the study introduces three theoretical contributions: the concept of the zoo-based digital learning ecology, the identification of the digital fragmentation problem, and the Integrated Digital Zoo Ecosystem (IDZE) model. The proposed framework conceptualizes digital visitor experience, animal welfare technologies, and conservation communication as interdependent subsystems within a unified sustainability-oriented ecosystem. This study provides a conceptual foundation for future sustainability-driven digital innovation in zoological parks.

Against the policy backdrop of high-quality development and the “Dual Carbon” goals, corporate environmental responsibility and green governance have emerged as core drivers of corporate value creation and resource allocation in capital markets. However, in practice, corporate environmental disclosure has increasingly degenerated into an impression management tool. Using a sample of China’s A-share listed companies from 2011 to 2024, this paper combines text analysis of annual reports with green patent data to systematically examine the impact of performance feedback on corporate strategic environmental decoupling, drawing upon the behavioral theory of the firm and legitimacy theory. The findings are as follows: First, negative performance feedback significantly increases corporate greenwashing propensity, whereas positive performance feedback significantly strengthens corporate brownwashing behavior. Second, government regulation amplifies the costs of falsifying environmental information, significantly suppressing the positive impact of negative performance feedback on greenwashing, but exacerbating the positive impact of positive performance feedback on brownwashing. Conversely, media attention amplifies the benefits of corporate green performances, significantly strengthening the catalytic effect of negative performance feedback on greenwashing, while effectively suppressing the positive impact of positive performance feedback on brownwashing. Third, heterogeneity analysis reveals that the impact of performance feedback on corporate strategic decoupling in environmental disclosure is more pronounced among non-state-owned enterprises, firms facing high industry competitive pressure, and those in heavily polluting industries. By integrating greenwashing and brownwashing into a unified analytical framework, this study expands the research boundaries of corporate environmental disclosure and strategic behaviors. Furthermore, it deepens the application contexts of the behavioral theory of the firm within non-financial disclosure, deconstructs the myth of homogeneous governance effects under legitimacy pressure, and provides vital implications for investors, policymakers, and fund managers.

Most air pollution research in India has predominantly focused on the Indo-Gangetic Plain (IGP) owing to its high pollution levels and dense populations, leaving peninsular India comparatively undercharacterized. In contrast, South India remains underexplored because of its relatively limited long-term monitoring and more favorable meteorology. This geographical imbalance restricts a comprehensive national understanding of particulate matter (PM) dynamics. Addressing this gap, the present study delivers a multi-scale (hourly to interannual) spatiotemporal assessments of PM2.5 across eight monitoring stations in Andhra Pradesh, a South Indian State, for the period 2020–2024. The analysis reveals pronounced seasonal variability, with persistent winter and post-monsoon maxima. Although overall concentrations are low compared to northern India, urban–industrial centers such as Visakhapatnam and Rajahmahendravaram frequently exceeded both the National Ambient Air Quality Standards (NAAQS) and World Health Organization (WHO) guidelines. Notably, Amaravati, a non-industrial and low-lying inland site, exhibited anomalously moderate PM2.5 levels, with ~11.58% of hourly values surpassing 60 µg m−3. The COVID-19 lockdown period further offered a natural experiment, revealing substantial reductions (30–65%) in PM2.5 and PM10 at major urban sites while concurrent ozone enhancements (up to ~50%) at Tirupati and Rajahmundry exposed complex photochemical sensitivity under reduced NOx conditions. Satellite-based MERRA-2 estimates corroborated inter-annual variability and the short-lived improvement in air quality. This study demonstrates that air quality dynamics in the state of Andhra Pradesh are governed by region-specific meteorological controls, episodic processes, and localized emission characteristics, necessitating expanded long-term monitoring infrastructure and improved satellite–ground calibration frameworks.
