Three of today's papers carry the tag "Urban Planning and Governance," examining governance mechanisms in Central and Eastern European urban redevelopment, migrant homemaking experiences in Kathmandu, and the discursive production of territorial stigma in Callao, Peru. The tag "interview" also covers three papers, which include the study on territorial stigma in Callao, an analysis of women's labor in Turkish film festivals, and an investigation into the urban experiences of caregivers of autistic individuals in Singapore. Outside these groups, one paper evaluated the 2025 Flower Community Fair in Accra as an informal learning platform for climate adaptation, another developed waveform analysis algorithms to identify train motion parameters from railway bridge strain data, and a third modeled a multi-period inventory pickup and delivery problem for rural logistics using alternative routes.

UNPACKING THE SUSTAINABILITY FIX: Governance Mechanisms in Urban Redevelopment Across Central and Eastern Europe

This study analyzes how sustainability functions as a governance strategy in large-scale urban redevelopment by examining the RIVUS Mall project in Cluj-Napoca alongside comparative cases from Bratislava and Gdańsk. It conceptualizes this process through three distinct mechanisms: material conversion of degraded land, discursive-financial mobilization of ecological narratives, and the structural embedding of green projects into territorial planning.

Why it matters — It demonstrates that sustainability objectives, rather than constraining market-led urbanism, serve as a flexible governance device that derisks speculative investments, justifies spatial intensification, and reconfigures state-market relations to facilitate capital accumulation.

Caveat: The findings are based on qualitative case studies of three specific Central and Eastern European cities, which may limit their direct applicability to regions with different planning cultures and financial structures.

Community fairs as platforms for urban greenery and climate change adaptation in Accra, Ghana

This study evaluated the 2025 Flower Community Fair in Accra, Ghana, as an informal learning platform for climate adaptation using a mixed-methods survey of 189 attendees alongside qualitative observations. The analysis measured participant demographics, their perceived relevance of home gardening, and their self-reported intentions to adopt greening practices after the event.

Why it matters — It demonstrates how localized, community-based events can convert existing environmental interest into explicit intentions for domestic climate adaptation in a rapidly urbanizing African context.

Caveat: The findings rely on self-reported intentions from a self-selected group of attendees rather than documented, long-term behavioral changes.

Identification of Load-Relevant Train Motion Parameters Using Strain Monitoring Data of High-Speed Railway Bridges

This study develops an analytical model and a set of waveform analysis algorithms to identify train motion parameters, including the number of carriages, direction of travel, and speed, using structural strain monitoring data from high-speed railway bridges. The method was validated using field monitoring data from an in-service high-speed railway steel truss bridge, successfully matching the identified parameters with actual train operations.

Why it matters — It provides a method to extract operational train characteristics directly from existing bridge strain sensors, enabling accurate train load identification and structural health monitoring without requiring dedicated trackside train-tracking hardware.

Caveat: The validation of the proposed method is demonstrated on a single in-service steel truss bridge, and its performance across different bridge types or structural materials is not detailed.

Home as temporary unless owned: migrant homemaking in contexts of legal absence

This study examines how migrant renters construct and experience the concept of home in Kathmandu, Nepal, where approximately half of the population consists of rural-to-urban migrants. Using ethnographic research and survey data, the study analyzes how the virtual absence of legal tenancy regulations and the lack of legal recognition for renters shape daily life.

Why it matters — It demonstrates that when tenancy relations are unregulated, renters internalize their housing precarity by viewing their urban homes as inherently temporary and unstable, shifting the understanding of homemaking from a process of settlement to one of managed transience.

Caveat: The findings are based on a qualitative and survey-based case study of a single rapidly urbanizing city in the Global South, which may limit generalizability to contexts with stronger legal frameworks.

Cities in emergency: stigma, discourse, and power in Callao, Peru

This study analyzes the discursive production of territorial stigma in Callao, Peru, by examining press media coverage, state-of-emergency decrees, institutional archives, and semi-structured interviews with local residents. It traces how the Peruvian state and media frame specific urban slums as dangerous, introducing the concept of the biopolitical enemy to explain how certain populations are subjected to governance through states of exception.

Why it matters — It demonstrates how state-led security discourses and media stigmatization are directly linked to urban renewal dynamics, showing that the construction of a territorial enemy is actively used to justify state control and physical restructuring in marginalized neighborhoods.

Caveat: The empirical findings are based on a qualitative case study of a single, highly stigmatized port city, which may limit direct generalizability to cities with different political or economic structures.

Rural multi-period inventory pickup and delivery problem with multi-attribute alternative routes: a case study

The study develops a mathematical model for the multi-period inventory pickup and delivery problem in rural logistics, incorporating alternative routes characterized by varying costs, accident risks, and toll fees. The model was tested using a tailored non-dominated sorting genetic algorithm II (NSGA-II) on a mixed urban-rural distribution network in North Florida, achieving a 7% to 14% reduction in both transportation costs and accident risks.

Why it matters — It introduces a routing optimization approach that simultaneously manages inventory over multiple periods and integrates return-trip pickups, allowing logistics planners to systematically trade off financial costs against safety risks on rural road networks.

Caveat: The model's performance and the reported 7% to 14% efficiency gains are demonstrated solely on a single case study in North Florida.

Women's labor in film festivals in Türkiye

This study analyzes women's labor and gender distribution across curatorial, administrative, and operational roles in four long-running Turkish film festivals. The researchers reviewed 133 festival catalogs and conducted 10 in-person and online interviews with female festival managers and employees to trace historical changes in participation.

Why it matters — It documents how gender disparities in the broader Turkish film industry are replicated within festival organizations, revealing that while women have increasingly managed film funds over the last decade, their roles in most festivals remain restricted to operational tasks rather than leadership or decision-making positions.

Caveat: The findings are based on a small qualitative sample of ten interviews across four specific, long-established festivals in a single country.

Portable elsewhere: re-mobility, marriage migration, and the ‘death of proximity’ among Ethiopian wives in China

Based on an eight-month multi-sited ethnography in Ethiopia and China alongside digital follow-up on WeChat, this study documents how Ethiopian wives in rural China experience severe destination-country immobility within multigenerational households. It details how language barriers, racialized visibility, and marriage-based residency rules restrict their movement, and how these women use smartphones to access a 'portable elsewhere' to coordinate survival strategies and plan relocation to Chinese cities.

Why it matters — The study demonstrates that physical co-residence does not guarantee social integration, showing instead how digital infrastructures like WeChat allow marginalized migrants to bypass physical isolation and organize secondary migration within the host country.

Caveat: The findings are based on qualitative ethnographic methods and digital tracking of a specific migrant corridor, which may not represent the dynamics of marriage migration in other national contexts.

Multi-objective traffic signal control considering pedestrian crossings via constraints-decoupled reinforcement learning

The study develops a multi-objective adaptive traffic signal controller that decouples vehicle and pedestrian movements using an option-action reinforcement learning framework. It implements a linear scalarization mechanism to balance pedestrian and vehicle efficiency under varying weight preferences, alongside a value function approximation method that aggregates movement-level Q-values into phase-level estimates using a conflict matrix.

Why it matters — The controller speeds up convergence compared to traditional phase-based adaptive controllers and reduces delays for both pedestrians and vehicles under fluctuating demand, providing a customizable balance between different road users.

Caveat: The performance and convergence advantages of the controller were evaluated exclusively within a simulation environment rather than through real-world deployment.

Determination of the Sample Size of Linear Features Used in Cartographic Quality Control Through Monte Carlo Simulation

This study developed a method to determine the required sample size for assessing the positional accuracy of linear features in cartographic quality control using Monte Carlo simulations. The method was tested on a database of 46,460 km of roads across 10 Spanish provinces, analyzing evaluation areas ranging from 1 to 250 square kilometers. Using the Kolmogorov-Smirnov test to compare samples against the population, the researchers produced an equation that calculates sample size based on the assessment area, achieving a coefficient of determination of 0.9252.

Why it matters — It establishes a mathematically rigorous, equation-based standard for sampling linear features like roads, filling a gap where sampling guidelines previously only existed for point-based positional accuracy.

Caveat: The proposed equation and its high predictive accuracy are based on a road network dataset from a single country, which may limit its direct applicability to regions with vastly different spatial road patterns.

Optimizing the Location and Size of Emergency Medical Service Stations in Urban–Rural Regions: A Case Study of Zhengzhou, China

The study develops a location and size optimization model for emergency medical service (EMS) stations that applies distinct planning parameters to urban and rural areas. The model was validated in Zhengzhou, China, using multi-source big data including population mobility and time-dependent traffic across multiple daily time periods to optimize the distribution of stations, ambulances, and crews.

Why it matters — It provides a planning framework that simultaneously reduces facility and personnel costs while improving emergency response times and service coverage, particularly addressing the spatial accessibility disparities in underserved rural areas.

Caveat: The model's performance and cost-reduction claims are based on operational simulations rather than a real-world deployment.

Who cares? Caregivers’ perspectives of non/encounters with autism in Singapore

This study analyzes the urban experiences of caregivers of autistic individuals in Singapore using thematic analysis of interviews and 'go-along' ethnographic observations with 18 caregivers, focusing on three detailed narratives. It examines how physical proximity in a densely populated city-state shapes both social encounters and deliberate non-encounters in public spaces.

Why it matters — It demonstrates that urban care is not solely a familial duty but a shared civic responsibility shaped by public interactions, showing how caregivers actively seek non-encounters to avoid exclusionary, ableist social norms.

Caveat: The findings rely on a small, qualitative sample of 18 caregivers in a highly specific, densely populated city-state, which may limit generalizability to less dense or culturally different urban environments.
