Unlike other American megacities, São Paulo's financial and administrative center has shifted multiple times, specifically four times over the last century. These shifts have significantly affected the city's former centers. This study examines the transformation of São Paulo's original center, the Historic Triangle, where layers of urban development that rapidly overlaid in the 20th century led to the demolition of historic buildings and verticalization. The shift of centrality subsequently caused the decay of this historic center. Despite the decline in its financial and administrative importance, the Historic Triangle remained a valuable site for its architectural heritage, though its cultural landscape and imageability are at risk. The data for this study was gathered from site surveys, historical maps, and experts' opinions and was analyzed using GIS and SPSS. An original 3D video was produced to illustrate the transformation and rapid verticalization of the Historic Triangle. To address the complex architectural landscape, the existing buildings are categorized into three generations: 1stG (oldest), 2ndG (transitional), and 3rdG (newest). We examined each category's façade details, building design, and urban integration and provided recommendations for conservation measures and policies to preserve the site's historical integrity and enhance its new role as a tourist heritage center.
与美国其他特大城市不同,圣保罗的金融和行政中心曾多次转移,特别是在上个世纪转移了四次。这些转移对城市的前中心产生了重大影响。本研究探讨了圣保罗最初的中心--历史三角区的变迁。20 世纪,层层叠叠的城市发展迅速叠加,导致了历史建筑的拆除和垂直化。中心位置的转移导致了这一历史中心的衰败。尽管在金融和行政方面的重要性有所下降,但历史三角区的建筑遗产仍具有重要价值,只是其文化景观和形象受到了威胁。本研究的数据来自现场调查、历史地图和专家意见,并使用 GIS 和 SPSS 进行了分析。还制作了一个原创 3D 视频,以说明历史三角区的转型和快速垂直化。针对复杂的建筑景观,将现有建筑分为三代:第一代(最古老)、第二代(过渡时期)和第三代(最新)。我们对每一类建筑的立面细节、建筑设计和城市融合进行了研究,并提出了保护措施和政策建议,以保护遗址的历史完整性,提升其作为旅游遗产中心的新角色。

With the transition to a market-oriented economic system and the transformation of social structure, urban society has undergone significant spatial differentiation, leading to a deepening divide between the rich and the poor. This has caused issues like social exclusion and spatial isolation to become increasingly prominent, which in turn, limit the harmonious and orderly development of cities. As Beijing's goal to become a “world-class harmonious and livable city” accelerates, there has been a growing focus on ensuring social justice satisfaction for residents in low-income communities. This focus has translated into more attention being paid to spatial equity in residents' living environments. Employing a mixed-methods approach with multi-level regressions to understand the nuanced interplay between urban geography and social equity, where depend variable was subjective questionary from low-income communities in Beijing (2017), the independent variables were geographical factors. Using research data from typical low-income communities in Beijing (2017), our study integrated theories from geography and sociology to examine the spatial equity of the living environment. We then empirically analyzed the impact of geographical environment and objective conditions on residents' perception of social equity in low-income communities. Our findings indicate that there are significant differences in the level of social justice perception among residents across different types of communities. The upscale community with better community environment is not consistent with the evaluation of higher perceived justice. Furthermore, service facilities, employment accessibility, and built environment all influence individual satisfaction with social justice to varying degrees. There is also a moderating effect of living environment satisfaction on social justice perception in low-income communities, with residents' socioeconomic attributes influencing their level of social justice satisfaction. This research contributes to the broader understanding of spatial equity in urban development, highlighting the pivotal role of geographical factors in shaping perceptions of social justice. These insights are crucial for policymakers and urban planners striving for more equitable urban development in rapidly growing cities.
随着经济体制向市场化转型和社会结构转型,城市社会空间分化明显,贫富分化日益加深。这导致社会排斥、空间隔离等问题日益突出,进而制约了城市的和谐有序发展。随着北京建设 "国际一流的和谐宜居之都 "目标的加快推进,确保低收入社区居民的社会公平满意度日益受到重视。这种关注已转化为对居民生活环境空间公平的更多关注。采用多层次回归的混合方法来理解城市地理与社会公平之间微妙的相互作用,其中因变量是来自北京低收入社区的主观问卷(2017 年),自变量是地理因素。我们的研究利用北京典型低收入社区的调研数据(2017 年),结合地理学和社会学理论,考察了居住环境的空间公平性。然后,我们实证分析了地理环境和客观条件对低收入社区居民社会公平感的影响。我们的研究结果表明,不同类型社区居民的社会公平感水平存在显著差异。社区环境较好的高档社区与较高的公平感知评价并不一致。此外,服务设施、就业便利性和建筑环境都会在不同程度上影响个人对社会公正的满意度。生活环境满意度对低收入社区的社会公正感也有调节作用,居民的社会经济属性会影响他们的社会公正满意度。这项研究有助于人们更广泛地理解城市发展中的空间公平问题,强调了地理因素在形成社会公平感方面的关键作用。这些见解对于在快速发展的城市中努力实现更加公平的城市发展的政策制定者和城市规划者来说至关重要。

A comprehensive understanding of house prices and their factors provide insights into the demand for housing while helping policymakers implement measures to manage the housing market. Traditional studies either focus more on linear relationships and ignore complex, non-linear influences or consider neighborhood amenities but lose sight of the streetscape. This study aims to enrich the literature by integrating street-perception characteristics with an interpretable machine-learning technique for modeling house prices. Specifically, street-view images were semantically segmented to quantify street-perception characteristics from five perspectives: greenness, openness, enclosure, walkability, and imageability. By combining the determinants of community attributes and living convenience, 17 explanatory variables were fed into a gradient-boosting decision tree (GBDT) model to estimate housing prices. The results reveal that the model significantly outperforms the linear model (R2 increased by 47.87 %). Additionally, an improvement of 26.15 % (R2) was observed when street-perception characteristics were incorporated. Moreover, complicated non-linear relationships and interaction effects are discussed by visualizing partial dependence plots (PDPs). These findings offer nuanced guidance for improving the neighborhood environment to promote urban equity and develop a sustainable housing market.
全面了解房价及其影响因素有助于深入了解住房需求,同时帮助政策制定者采取措施管理住房市场。传统的研究要么更多地关注线性关系而忽视复杂的非线性影响因素,要么只考虑街区设施而忽视街道景观。本研究旨在将街道感知特征与可解释的房价建模机器学习技术相结合,从而丰富相关文献。具体来说,对街景图像进行语义分割,从五个角度量化街道感知特征:绿化、开放性、封闭性、可步行性和形象性。结合社区属性和生活便利性的决定因素,将 17 个解释变量输入梯度提升决策树(GBDT)模型,以估算房价。结果显示,该模型明显优于线性模型(R2 提高了 47.87%)。此外,在加入街道感知特征后,R2 提高了 26.15%。此外,还通过可视化局部依存图(PDP)讨论了复杂的非线性关系和交互效应。这些发现为改善街区环境以促进城市公平和发展可持续住房市场提供了细致入微的指导。

What determines urban vitality has been a key research topic for urban planning and management since Jane Jacobs. Recently, statistical examinations of the relationship between the urban environment and vitality have become possible, facilitated by the availability of human positioning big data and fine-grained built environment data. However, existing studies tend to oversimplify the spatial impact of urban environmental factors, focusing solely on immediate surroundings. Due to people's trip chaining and exploration behavior, a place's functions can have a “spill-over” effect across the urban space. This study, therefore, aims to investigate such “attraction gradient” of urban functions to better understand the spatial relationship between urban vitality and its influencing factors. The study uses mobile phone and point-of-interest data from Beijing and Chengdu, China, to model the relationship between a place's vitality and urban functions in different distance bands. We find that, when counting from a place, urban functions within five kilometers significantly predict urban vitality, whereas beyond five kilometers, their contribution is marginal. Daytime and nighttime attraction gradients also differ. This study offers insights into the spatial relationship between urban function and vitality, enhancing our understanding and modelling of urban vitality.
自简-雅各布斯以来,城市活力的决定因素一直是城市规划和管理的关键研究课题。最近,由于人类定位大数据和精细的建筑环境数据的出现,对城市环境与活力之间关系的统计研究成为可能。然而,现有研究往往将城市环境因素的空间影响过于简单化,只关注周边环境。由于人们的出行链和探索行为,一个地方的功能会对整个城市空间产生 "溢出 "效应。因此,本研究旨在研究城市功能的这种 "吸引力梯度",以更好地理解城市活力与其影响因素之间的空间关系。本研究利用中国北京和成都的手机数据和兴趣点数据,建立了不同距离带的地方活力与城市功能之间的关系模型。我们发现,从一个地方算起,五公里以内的城市功能对城市活力有显著的预测作用,而五公里以外的城市功能对城市活力的贡献则微乎其微。白天和夜间的吸引力梯度也有所不同。这项研究有助于我们深入了解城市功能与活力之间的空间关系,从而加强我们对城市活力的理解和建模。

Reimagining urban waste management: Addressing social, climate, and resource challenges in modern cities 重新构想城市废物管理:应对现代城市的社会、气候和资源挑战

Governments worldwide are seeking better solutions for solid waste management. Thermal treatment projects are presented as quick fixes for rising waste challenges, without addressing the limitations of incineration. Currently, there is a rise in proposals for thermal treatment technologies in developing countries. Scrutiny of the risks and impacts of these alternatives is necessary due to social, climate, and resource considerations. Energy from waste incineration is considered fossil energy since about half of the CO2 emissions come from fossil polymers in the waste. From a sustainability perspective, landfilling is a short-term option for materials currently unsuitable for recycling. Landfills act as bioreactors, producing valuable biogas, and serve as “resource banks,” storing unrecyclable resources until better recycling techniques are developed. In developing countries manual labor is abundant and material sorting and landfilling are more valuable and have a lower climate and resource footprint. This paper offers a novel, integrated perspective of waste management in view of poverty reduction, climate change and resource conservation.
世界各国政府都在寻求更好的固体废物管理解决方案。热处理项目被视为应对日益严峻的废物挑战的快速解决方案,但却没有解决焚烧的局限性。目前,发展中国家关于热处理技术的建议越来越多。出于社会、气候和资源方面的考虑,有必要对这些替代技术的风险和影响进行审查。垃圾焚烧产生的能源被视为化石能源,因为大约一半的二氧化碳排放来自垃圾中的化石聚合物。从可持续发展的角度来看,垃圾填埋是目前不适合回收利用的材料的短期选择。垃圾填埋可作为生物反应器,产生有价值的沼气,还可作为 "资源库",储存不可回收的资源,直到开发出更好的回收技术。在发展中国家,人工劳动力丰富,而材料分类和填埋更有价值,对气候和资源的影响也更小。本文从减贫、气候变化和资源保护的角度,为废物管理提供了一个新颖的综合视角。

How do cities become more democratic? While some view local government as harboring greater democratic opportunities than the state, others identify local obstacles that inhibit democratization. Building on ideas of democratic populism, this article contributes to existing research on the right to the city by demonstrating how the construction of “an urban people,” and rhetoric and practices of urban populism can push for local democratization. Empirical analysis of the Tel Aviv-Jaffa 2008 municipal elections and their aftermath reveals that defining and engaging with a notion of the city's “ordinary people” can serve to further urban democracy. Four mutually reinforcing levels of transformative populism are identified: transformation of discourse, participation, rules of the game, and policy. The findings of this study suggest that democratically transforming discourse faces less resistance from local elites than transforming participation, the rules of the game, and policy.
城市如何变得更加民主?一些人认为地方政府比国家拥有更多的民主机会,而另一些人则认为地方政府存在阻碍民主化的障碍。本文以民主民粹主义思想为基础,通过展示 "城市人民 "的构建以及城市民粹主义的言论和实践如何推动地方民主化,为现有的城市权研究做出贡献。对特拉维夫-雅法 2008 年市政选举及其后果的实证分析表明,定义并参与城市 "普通人 "的概念有助于推进城市民主。研究确定了变革型民粹主义的四个相辅相成的层面:话语变革、参与、游戏规则和政策。研究结果表明,与参与、游戏规则和政策的变革相比,话语的民主变革所面临的地方精英阻力较小。

Urban–rural imbalance is a common phenomenon, and its prominent manifestation is the sustained expansion of the urban–rural income gap. For emerging countries, this gap encountered during the development process should be addressed by promoting development, which also puts forward high requirements for economic management. Inspired by political economy theory and the widening urban–rural income gap in China, this study constructs a theoretical framework of “purpose-behavior-performance-structure” based on the urban bias theory, and then quantitatively examines the effect of economic growth target on the urban–rural income gap based on panel data at the provincial level. In addition, we explore the mechanism by which economic growth targets affect the urban–rural income gap with the mediating effect model, and investigate the impact of marketization and spatial structure on the relationship between economic growth targets and urban–rural income gap with the moderating effect model. The results show that the economic growth target significantly contributes to the widening urban–rural income gap in the face of the political promotion incentives and economic growth target accountability system, and this effect exhibits substantial spatiotemporal heterogeneity. In addition, fiscal expenditure, fixed asset investment, and labor mismatch under urban bias are important mechanisms that lead to the widening urban–rural income gap, and the marketization level and spatial structure significantly affect this relationship. We put economic growth management, urban bias, and urban–rural income gap into the “purpose-behavior-performance-structure” theoretical framework, which provides a new explanatory perspective for understanding the urban–rural income gap in emerging economies, and new policy insights for rational economic growth management.
城乡失衡是一个普遍现象,其突出表现就是城乡收入差距持续扩大。对于新兴国家来说,在发展过程中遇到的这种差距需要通过促进发展来解决,这也对经济管理提出了很高的要求。受政治经济学理论和中国城乡收入差距扩大的启发,本研究在城市偏差理论的基础上构建了 "目的-行为-绩效-结构 "的理论框架,并基于省级面板数据定量检验了经济增长目标对城乡收入差距的影响。此外,我们还利用中介效应模型探讨了经济增长目标对城乡收入差距的影响机制,并利用调节效应模型研究了市场化和空间结构对经济增长目标与城乡收入差距关系的影响。结果表明,在政治晋升激励和经济增长目标责任制的作用下,经济增长目标对城乡收入差距的扩大有显著的促进作用,而且这种作用表现出很大的时空异质性。此外,城市偏向下的财政支出、固定资产投资和劳动力错配也是导致城乡收入差距扩大的重要机制,而市场化水平和空间结构会显著影响这种关系。我们将经济增长管理、城市偏向和城乡收入差距纳入 "目的-行为-绩效-结构 "的理论框架,为理解新兴经济体的城乡收入差距提供了新的解释视角,也为合理的经济增长管理提供了新的政策启示。

Inspired by political economy theory and the widening urban–rural income gap in China, this study constructs a theoretical framework of “purpose-behavior-performance-structure” based on the urban bias theory, and then quantitatively examines the effect of economic growth target on the urban–rural income gap based on panel data at the provincial level. In addition, we explore the mechanism by which economic growth targets affect the urban–rural income gap with the mediating effect model, and investigate the impact of marketization and spatial structure on the relationship between economic growth targets and urban–rural income gap with the moderating effect model. The results show that the economic growth target significantly contributes to the widening urban–rural income gap in the face of the political promotion incentives and economic growth target accountability system, and this effect exhibits substantial spatiotemporal heterogeneity. In addition, fiscal expenditure, fixed asset investment, and labor mismatch under urban bias are important mechanisms that lead to the widening urban–rural income gap, and the marketization level and spatial structure significantly affect this relationship. We put economic growth management, urban bias, and urban–rural income gap into the “purpose-behavior-performance-structure” theoretical framework, which provides a new explanatory perspective for understanding the urban–rural income gap in emerging economies, and new policy insights for rational economic growth management.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"156 ","pages":"Article 105518"},"PeriodicalIF":6.0,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research suggests that investment in the form of structural home repairs, new construction, and home renovation is associated with crime reductions in residential areas. The current study examines how the relationship between investment and crime on residential street segments is moderated by neighborhood characteristics using longitudinal data from six large U.S. cities to better understand how investment strategies can be targeted to maximize public safety benefits. We estimate spatial Durbin models with street segment and census tract by year fixed effects to examine the effects of one measure of direct investment, building permits, on changes in crime at street segments and the extent to which such effects vary by census tract-level concentrated disadvantage, residential stability, median housing values, percent non-White, percent foreign-born, and population density. Findings reveal a significant negative relationship between permit activity and changes in crime in all cities. With few exceptions, effects were strongest among segments in the densest neighborhoods with the highest percentage of foreign-born residents where concentrated disadvantage is high and residential stability and median home values are low. The moderating influence of the racial and ethnic residential population varied across cities. We discuss implications, including avoiding unintended consequences associated with investment.
研究表明,以房屋结构维修、新建筑和房屋翻新等形式进行的投资与住宅区犯罪率的降低有关。本研究利用美国 6 个大城市的纵向数据,研究了投资与住宅街段犯罪之间的关系如何受邻里特征的调节,从而更好地了解如何有针对性地制定投资策略,以最大限度地提高公共安全效益。我们估算了具有街道区段和人口普查区年固定效应的空间杜宾模型,以研究直接投资的一种衡量标准--建筑许可--对街道区段犯罪率变化的影响,以及这种影响因人口普查区层面的集中劣势、居住稳定性、住房价值中值、非白人比例、外国出生人口比例和人口密度而不同的程度。研究结果表明,在所有城市中,许可活动与犯罪率变化之间存在明显的负相关关系。除少数例外情况外,在人口密度最高、外国出生居民比例最高的社区,其影响最大,因为这些社区的集中劣势较高,而居住稳定性和房屋价值中位数较低。种族和民族居住人口的调节作用因城市而异。我们讨论了相关影响,包括避免与投资相关的意外后果。

The coronavirus pandemic forced local support services in marginalised communities to adapt how they operated at the same time as demand for assistance soared. Social distancing restrictions brought into sharp relief the infrastructural dimensions of social care and support services and networks that are often backgrounded in day-to-day practice. A shadow care infrastructures lens looks purposively at care infrastructures that are not readily seen or acknowledged in dominant welfare discourse and research (Power, Wiesel, Mitchell, & Mee, 2022). Taking this analytic lens as our starting point, in this paper we explore how relations of care were reconfigured by the shift to remote care delivery during Covid-19 lockdowns and beyond. The challenges of providing care during lockdown reveal the complex interplay between distance and proximity in care relations and practices and the possibilities for doing care differently. The paper draws primarily on in-depth interviews with paid and voluntary supporters across a diverse range of care organisations servicing two Local Government Areas (LGAs) in Central Western Sydney. A gateway region for new migrants west of the population centre of Sydney, it was one of the areas worst affected by the outbreak of the Delta variant of Covid-19 in 2021. The paper reflects on the potential longevity of pandemic care practices as cities learn to live with Covid.
冠状病毒大流行迫使边缘化社区的地方支持服务机构在援助需求激增的同时调整运作方式。社会疏远的限制使社会关怀和支持服务及网络的基础设施层面变得更加突出,而这些方面在日常实践中往往被忽视。影子照护基础设施的视角有目的性地关注那些在主流福利话语和研究中不容易被看到或承认的照护基础设施(Power, Wiesel, Mitchell, & Mee, 2022)。以这一分析视角为出发点,我们将在本文中探讨在科维德-19 封锁期间及之后,护理关系是如何通过向远程护理服务的转变而被重构的。在封锁期间提供护理所面临的挑战揭示了护理关系和实践中远近之间复杂的相互作用,以及以不同方式提供护理的可能性。本文主要利用了对悉尼中西部两个地方政府辖区(LGAs)的各种护理组织的有偿和志愿支持者的深入访谈。该地区是悉尼人口中心以西新移民的门户地区,也是 2021 年三角洲变种 Covid-19 爆发后受影响最严重的地区之一。本文探讨了在城市学会与 Covid 共存的过程中,大流行病护理实践的潜在长期性。

Rapid urban growth extends the boundaries of urbanized areas and makes people spend extra travel cost on the journey to work. Scholars have examined commuting behaviors between residence and work places within a region, and suggested the conceptual theory of jobs-housing balance to evaluate if there are sufficient job opportunities for residents in the region. A quantitative measurement of excess commuting is proposed to reflect the degree of jobs-house balance. However, current studies focus on the evaluation of excess commuting and the causality of spatial restructuring between residence and workplace, the spatial extend of excess commuting in an urban region is not visually delineated. In addition, conventional studies acquire static data such as statistic data or other survey data to analyze impacts of commuting patterns on urban formation. Today the emergence of spatial big data sheds light on the causality of urban commuting from higher spatial and temporal resolutions. This study aims to examine the degree of jobs-housing balance through the calculation of excess commuting and represent the spatial extent of excess commuting of Taichung metropolitan area in Taiwan. Electronic Toll Collection (ETC) data, the spatial big data which is publicly accessible in Taiwan, is introduced as the commuting data and to calculate three key parameters of excess commuting, Tmin, Tobs, and Tmax. The three parameters are used to visualize the extent of commuting zones and examine commuting patterns of Taichung metropolitan area and observe the spatial relationship between those patterns and land-use types. The evaluation of excess commuting indicates that the degree of jobs-housing imbalance in Taichung metropolitan area is similar to Los Angeles metropolis in US. The analytical results explain how ETC data can be successfully used for the calculation of excess commuting, and visualization of the extent of commuting regions. In addition, after the cluster analysis of residential areas, it is intuitive to observe spatial correlation between hot zones of residential areas and the spatial extent of theoretical maximum commuting, and shows that the scenarios of commuting can be considered as an indicator to explain the possibility of urban expansion in the future.
城市的快速发展扩大了城市化地区的边界,使人们在上班途中花费了额外的交通成本。学者们研究了区域内居住地与工作地之间的通勤行为,并提出了职住平衡的概念理论,以评估区域内居民是否有足够的就业机会。有学者提出了对过量通勤的量化测量方法,以反映就业-住房平衡的程度。然而,目前的研究主要集中在对过度通勤的评估以及居住地与工作地之间空间结构调整的因果关系上,城市地区过度通勤的空间延伸并没有得到直观的描述。此外,传统研究都是通过统计数据或其他调查数据等静态数据来分析通勤模式对城市形成的影响。如今,空间大数据的出现从更高的时空分辨率揭示了城市通勤的因果关系。本研究旨在通过计算过剩通勤量来检验就业与住房的平衡程度,并呈现台湾台中都会区过剩通勤量的空间范围。本研究引入台湾公开的空间大数据--电子收费站(ETC)数据作为通勤数据,并计算出过量通勤的三个关键参数:Tmin、Tobs 和 Tmax。通过这三个参数,可以直观地看出通勤区的范围,研究台中都会区的通勤模式,并观察这些模式与土地利用类型之间的空间关系。对过度通勤的评估表明,台中都会区的职住失衡程度与美国洛杉矶都会区相似。分析结果解释了如何成功利用 ETC 数据计算过量通勤,以及通勤区域范围的可视化。此外,经过居住区聚类分析,直观地观察到居住区热点区域与理论最大通勤空间范围之间的空间相关性,说明通勤情景可作为解释未来城市扩张可能性的指标。
