Urban forest parks significantly influence tourists' post-visit behaviors, such as repeat visits and recommendations, by shaping their environmental preferences and perceived satisfaction. The study identifies two key psychological paths: a direct path where the park's recreational environment directly affects behavioral intention, and an indirect path where environmental preference leads to satisfaction, which then stimulates deeper evaluation and positive behavioral intentions. This dual mechanism highlights the importance of enhancing tourists' experience through environmental perception and satisfaction to foster long-term engagement with urban forest parks. The research provides actionable insights for planning and management, emphasizing the role of spatial physical environment, cultural characteristics, and service experiences in shaping tourist behavior.

A significant decline in per capita non-sorted municipal solid waste (MSW) generation has been observed in Ibiza, with a more pronounced reduction among the non-tourist population. This trend, alongside an increase in sorted waste collection, suggests the growing adoption of circular economy practices. The study differentiates waste generation patterns between tourists and locals using the STIRPAT model, revealing that these patterns vary by season, population type, and waste category. While both groups show a decrease in non-sorted waste, sorted waste per capita has risen, indicating improved recycling efforts. These findings underscore the complex interplay of tourism, seasonality, and waste management strategies in shaping sustainability outcomes.

Traditional houses in Erbil, Kurdistan, Iraq, demonstrate superior thermal comfort compared to modern counterparts due to their passive and natural building techniques. A study found that traditional houses maintain indoor temperatures between 21.2°C and 26.3°C with low humidity (9%–11%), aligning with ASHRAE-recommended comfort zones, while modern houses struggle, recording temperatures between 28°C and 37°C with higher humidity (12%–16%). The research, conducted during June and July 2023 under typical summer conditions (maximum outdoor temperature: 39–41°C), used adaptive thermal comfort models for validation. By comparing four modern houses in Erbil with a traditional case from the Erbil Citadel, the study highlights the potential of integrating traditional architectural features to improve indoor thermal conditions in contemporary housing.

Speyer Cathedral, as the sole authentic 'Kaiserdom' (imperial cathedral), stands out for its historical significance as an imperial mausoleum where four Holy Roman emperors and five German kings were buried between the 10th and 14th centuries. Unlike Mainz and Worms cathedrals, which lack direct imperial ties, Speyer's role was comparable to that of Westminster Abbey or St-Denis in France. The term 'Kaiserdom' now extends to all three due to their striking stylistic similarities—low octagonal central towers flanked by four slender stair-towers—though Mainz later altered its appearance by raising its central tower. This study clarifies the distinction between Speyer's imperial legacy and the architectural relationships among these cathedrals, emphasizing their collective medieval significance.
