The cases share a monolithic, single-owner morphology with low perimeter permeability and consumption-oriented quasi-public realms. Ground-floor public open-space provision is conspicuously low (approximately 11 % at Zorlu, and about 5 % at Mall of Istanbul and Metropol), well below neighborhood-scale expectations derived from Istanbul's planning standards. Conceptually, the study situates these patterns within graduated sovereignty and planning-by-exception, showing how formal instruments are selectively mobilized to reallocate public or formerly public land for private returns. Building on these findings, the article advances auditable policy tools, minimum perimeter porosity and non-paywalled ratios in plan notes; ring-fenced value capture to deliver at-grade links and green areas; and a Social-Use Overlay to secure affordability when public/formerly public parcels are upzoned or disposed.

Analysis of UK census data from 2001, 2011 and 2021 and GIS analysis tracked changes in population composition nearby (0–300 m) and in the wider area (301–1000 m) surrounding the wetlands indicates that within 300 m of these wetlands, there has been a rise in non-deprived, university-educated residents and a decrease in socially rented housing, compared to 1000 m away. This suggests that nearby private (re)development in tandem with BGI projects may be contributing to green gentrification.

We surveyed 325 high-school students in Sydney, Australia, exploring their demographics, cycling attitudes, perceptions of safety, and environmental factors that influence their bicycle use. The data is analysed through two logistic regression models, one for recreational cycling and the other for school commuting, both reinforced by the synthetic minority oversampling technique to address class imbalances. Recreation emerged as the primary motivation for cycling, with students more likely to ride when accompanied by friends or family. There are more recreational cyclists than commuters, likely due to the lack of safe cycling routes, heavy loads during commuting, and insufficient bike parking at schools. The smaller group of commuting cyclists tends to use bicycles more consistently and frequently and exhibit greater risk acceptance towards cycling infrastructure. To encourage cycling to school, we recommend the establishment of dedicated bike lanes to schools completely separated from vehicular traffic and increased bike parking facilities at schools, as well as government subsidies and incentives for cargo racks and e-bike promotion.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"169 ","pages":"Article 106513"},"PeriodicalIF":6.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145223042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this process, the urban scaling structure that governs how local places interact and collectively shape scaling-distributed mobility patterns plays a critical role. This study built a spatially explicit agent-based model to explore how the origin place of new variants can influence subsequent transmission dynamics. We found small differences in initial invasion places had path-dependent effects on resilience outcomes. Structurally more important places can facilitate the occurrence of new outbreaks. However, surprisingly, outbreaks originated in structurally less important places show more explosive early spread. This early spread advantage can be attributed to survivorship bias: invasions originating from the less favourable environments had to be more vigorous to guarantee successful breakthroughs. Nevertheless, this early spread advantage was not sustained because the more dispersed waves of early spread may lead to greater energy loss in subsequent spread progression.

Additionally, it provides an analysis of the challenges and opportunities associated with environmental sustainability in prisons and advocates the need for a comprehensive approach to correctional management that aligns ecological responsibility with prisoner education and community engagement.
