Energy security has become a strategic priority for ensuring sustainable economic development, particularly for European Union (EU) countries characterized by high external energy dependence. This study investigates the key drivers of energy security risks in selected EU countries over the period 1995–2018, focusing on economic growth, tourism expenditures, technological innovation, renewable energy consumption, and urbanization. The empirical analysis employs panel vector autoregression and a panel error correction model to examine short- and long-run causal dynamics, while the augmented mean group estimator captures cross-country heterogeneity. The findings indicate that economic growth is the primary short-run determinant of energy security risk, whereas all variables exert significant long-run effects. Country-level results reveal common patterns for growth, renewable energy consumption, and urbanization, but heterogeneous impacts for tourism and technological innovation. These results suggest that strengthening renewable energy adoption, promoting innovation, and supporting sustainable urban development can enhance long-term energy resilience. Overall, this study provides policy-relevant insights for designing sustainability-oriented energy strategies aligned with the European Union’s climate transition goals.

This study examines how ethical leadership promotes employees’ corporate social responsibility (CSR) engagement in small- and medium-sized enterprises (SMEs) through a sequential mechanism of Trust in leadership and organizational commitment, and whether this process differs across national contexts. Survey data were collected from SME employees in Pakistan (n = 102), India (n = 70), and Taiwan (n = 96). Using a multi-group partial least squares structural equation modeling (PLS-SEM) approach with bootstrapping, we test direct, indirect, sequential mediation, and moderation effects linked to national culture (collectivism) and institutional support. Results show that ethical leadership has a positive direct effect on CSR engagement and an additional indirect effect via Trust in leadership and organizational commitment. The strength of these relationships varies across the three countries, underscoring the importance of cultural and institutional conditions when translating leadership ethics into CSR-oriented behaviors. The findings extend CSR micro foundations in SMEs and offer actionable guidance for leadership development and policy support in emerging and advanced economies.

The Portuguese Water Quality Policy, aligned with the Water Framework Directive, requires the monitoring of shellfish production in coastal and brackish water bodies and isbased on the EC Shellfish Waters Directive; it preserves the environmental conditions necessary for shellfish growth and contributes to the production of a safe, high-quality sustainable animal food source. Between 2017 and 2021, quarterly measurements of physico-chemical and microbial parameters were conducted at 11 coastal stations and 21 estuarine/coastal lagoons stations along Portugal, to evaluate shellfish water quality and identify the environmental drivers influencing it. Results showed that estuaries and coastal lagoons were more vulnerable to fluctuations in salinity, oxygen and suspended matter and consistently exhibited higher faecal contamination in bivalves than coastal waters. These patterns were shaped by freshwater inputs, climate-driven variability, and local anthropogenic pressures, with contamination often increasing during rainy periods or under stressful environmental conditions. The study highlights the sensitivity of transitional waters to both natural and human-induced changes and underscores the need for targeted management strategies, such as improved wastewater treatment and integrated coastal management, to reduce pollution pressures. Strengthening these measures is essential for the long-term sustainability of Portugal’s shellfish industry and coastal ecosystems.

Circular economy (CE) claims in fashion aim to mobilize consumer participation in reuse and recycling, yet the interpretative flexibility of “circular” language can also enable vague messaging and skepticism. This study investigates how consumers assess CE fashion claims in terms of (a) claim substantiation quality (CSQ) and (b) claim support credibility (CSC), and how these assessments influence perceived green authenticity (PGA), green trust (GTR), and circular purchase intention (CPI) in Greece and the United Kingdom. A cross-national online stimulus-based survey utilizing standardized e-commerce product-card claims for a fictitious circular fashion brand gathered data from Greece (n = 640) and the UK (n = 572). PLS-SEM and multi-group analysis evaluated a model distinguishing CSQ and CSC as complementary message properties. In the overall sample, both CSQ and CSC exhibited a positive correlation with CPI, whereas PGA and GTR emerged as the most significant proximal predictors, with authenticity demonstrating the most substantial impact. Indirect-effect tests showed that CSQ affected CPI through both authenticity and trust. On the other hand, CSC was only effective through authenticity, and there was no clear pathway for CSC trust intention. The multi-group results also showed context sensitivity: Greece exhibited a stronger trust-based path to intention, while the UK had a stronger authenticity-based path to intention. Overall, the results support a dual-route theory of CE claim persuasion. Additionally, they suggest that effective CE fashion communication should combine clear, specific content with credible, externally checkable support cues.

Against the backdrop of population aging, community parks are important spaces for older adults’ daily activities, and perceived safety plays a key role in shaping their use and spatial satisfaction. This study selected six typical community parks in central Beijing, constructed an indicator system for safety perception needs, and applied an analytical KANO–IPA (Integrated Kano and Importance-Performance Analysis) approach to identify the demand attributes and optimization priorities of safety elements. The results reveal a clear hierarchy in older adults’ safety perception needs. Basic environmental and facility safety factors, such as pavement conditions and facility reliability, function as must-be needs. Elements related to spatial visibility, circulation, lighting, and wayfinding act as one-dimensional needs that steadily influence satisfaction, whereas features including natural surveillance, spatial enclosure, and activity atmosphere mainly enhance spatial experience as attractive needs. Priority analysis further indicates that circulation conditions and facility safety constitute the most critical aspects for improvement. Overall, older adults’ safety perception in community parks results from the combined effects of multiple spatial factors. Hierarchical spatial optimization can enhance user experience and improve resource allocation efficiency. The findings provide theoretical support and decision-making guidance for safety-oriented planning and age-friendly renewal of urban community parks in aging societies.
