This study focuses on the social conflicts arising from the commercialization-driven renewal of the Workers' Village community in Chengdu. Using a combination of case study methods, structured interviews, and participant observation, we explore the public value conflicts and their resolution pathways in the process of community renewal. The study reveals that the formation of public values is a dynamic process characterized by the interplay of multiple value systems, with various public value conflicts emerging in the commercialization of communities. To resolve these social conflicts, it is essential to fully consider the diverse interests of different groups and contexts, as well as the varying public values at stake. By promoting democratization and institutionalization, the different public values that arise from these conflicts can be transformed into a widely recognized value consensus. Grounded in public value theory, this study proposes a social conflict resolution model that transcends traditional approaches. It not only examines the key stakeholders involved in social conflicts during community renewal and the manifestations of value conflicts among them, but also emphasizes the importance of integrating and transforming divergent public values through active dialogue and negotiation. This process, involving multiple stakeholders, follows a trajectory from the aggregation of public values to negotiation and ultimately to value reshaping. The proposed model provides a new governance framework and methodological support for addressing social conflicts in community renewal, offering innovative insights into the integration and reconciliation of public values.</div></div>","PeriodicalId":45131,"journal":{"name":"Journal of Urban Management","volume":"14 2","pages":"Pages 402-417"},"PeriodicalIF":3.9,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143948284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a scarcity of understanding of nighttime safety despite the fast-growing body of urban scene auditing research based on daytime street view imagery (SVI). To fill the gap, this study collected ∼1000 pairwise day-and-night SVIs to train a day-to-night (D2N) SVI generator to effectively predict nighttime SVI based on daytime counterpart using generative adversarial network (GAN). The accuracy of fake nighttime image was evaluated with commonly-used GAN metrics (e.g., structural similarity index, inception score) and human validation. Then, an online visual survey with 46 participants was conducted to collect their perceived safety on street scenes during daytime and nighttime (D&N), and the results become training labels for machine learning models to predict D&N safety perceptions. Our results revealed significant discrepancies in D&N safety perception. First, through correlation analysis, we found that the sky and building features matter to the prediction accuracy of generated nighttime SVIs. Second, the micro-level streetscape features (e.g., pavements, roads, and buildings) play influential roles in perceived safety. Third, higher safety perceptions are consistently found in areas with higher building density regardless of whether they are daytime or night. In contrast, untended trees and grass reduce perceived safety at night. This study provides a valuable reference for improving the accuracy of generating nighttime images from daytime SVIs. It also reveals how streetscapes affect D&N safety perceptions in high-density cities like Hong Kong, providing empirical evidence for urban design policies to facilitate nighttime attractiveness and prosperity.</div></div>","PeriodicalId":45131,"journal":{"name":"Journal of Urban Management","volume":"14 2","pages":"Pages 379-401"},"PeriodicalIF":3.9,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143948283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent decades, GC has witnessed massive urban expansion, which has yet to be empirically measured or characterized. This research seeks to explore the patterns of urban growth and changes in urban form in GC from 1973 to 2021 using remote sensing and geospatial metrics. Six Landsat images in 1973, 1984, 1992, 2003, 2013, and 2021 were used to explore urban growth in GC. Urban Land Density Function (ULDF), Landscape Expansion Index (LEI), and Fractal Dimension Index (FDI), were utilized to analyze various aspects of urban expansion. Additionally, the ratio of Land Consumption Rate (LCR) to Population Growth Rate (PGR) was calculated to assess the correlation between urban expansion and population changes. Our results reveal a substantial addition of 203 thousand hectares of urban areas over the last half-century. The ULDF highlights GC’s transformation from a condensed to a scattered urban landscape, particularly with the establishment of the New Administrative Capital in the vicinity. Edge expansion emerged as the principal type of urban growth throughout the research duration. The consistent increase in FDI from 1.44 in 1973 to 1.75 in 2021 signifies the fragmentation of the urban landscape. Moreover, the progressive rise in LCR from 0.023 in 1984 to 0.050 ha per person in 2021 suggests a steady expansion of low-density urban areas. Notably, the LCR-to-PGR ratio escalated from 0.878 in 1984 to 2.428 in 2021, indicating that urban expansion surpassed population growth. These results will help further understand the characteristics of GC’s urban expansion and may offer a scientific foundation for policymakers to reconsider the current horizontal expansion policy in GC.</div></div>","PeriodicalId":45131,"journal":{"name":"Journal of Urban Management","volume":"13 4","pages":"Pages 565-579"},"PeriodicalIF":3.9,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142702259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous research has extensively explored the spatial equity of educational resources in developed countries; however, there's a lack of adequate studies focused on cities within developing regions, like Erbil. Also, the impact of the double-shift school system on educational equity remains significantly unexplored. This study employs statistical techniques (Location Quotient and Pearson's correlation) to analyze the spatial concentration and the relationship between primary schools and population numbers. Additionally, GIS is utilized to examine factors affecting educational equity, focusing on the spatial distribution of government primary schools and their relation to population density and housing prices. These techniques include mean center, central feature, standard distance, kernel density, average nearest neighborhood, buffer zones, and Thiessen polygons to analyze schools' geographical distribution, density, patterns, accessibility, proximity, and school location assessment. Furthermore, this study analyzes the effects of different school systems on equity by examining instructional time. The results showed an uneven distribution of schools, concentrated in older areas with a scarcity on the city's outskirts, and a negative correlation between school numbers and housing prices. Notably, about 88% of Erbil's primary schools operate double shifts due to insufficient numbers, which reduces annual instruction time to 576 hours, significantly lower than in other school systems. By proposing an equity priority model for future schools and emphasizing the efficient allocation of educational resources, this study contributes to global discussions on educational disparities and suggests strategies for equitable resource distribution in urban settings.</div></div>","PeriodicalId":45131,"journal":{"name":"Journal of Urban Management","volume":"13 4","pages":"Pages 832-849"},"PeriodicalIF":3.9,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142702338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
