Cultural assets are increasingly recognized as vital catalysts for post-disaster urban recovery. However, despite their importance, a critical theoretical gap remains in understanding how communities mobilize these assets to meet the capital and institutional requirements of large-scale heritage reconstruction. Using the Pimbahal Pond Area of Patan, Nepal, as a case study, this research explores community-led urban revitalization following the 2015 Gorkha Earthquake. This study employs a qualitative methodology and uses the Asset-Based Community Development (ABCD) framework as a foundational lens. Results indicate that a model of Strategic Interdependence is key to a successful revitalization, rather than insular localism. This model facilitated a formalized hybrid governance structure that enabled dynamic collaboration among residents, metropolitan authorities, and international partners. Findings revealed that this model enabled the community to leverage its cultural assets and social capital to negotiate for and co-manage external resources. The process not only ensured an authentic reconstruction but also established a self-sustaining financial and social foundation. Nevertheless, the successful revitalization introduced new challenges of the commodification of culture and the contestation of public space. The main contribution of this research is the formulation of Strategic Interdependence as a necessary theoretical extension of ABCD. It argues that while the asset-based approaches hold significant potential for community-led urban revitalization, their implementation requires careful consideration of power dynamics, cultural integrity, and long-term sustainability. Finally, this study contributes to the knowledge of post-disaster recovery of culturally sensitive assets, providing a transferable model for urban planning and heritage management, particularly in the Global South.

文化资产日益被认为是灾后城市恢复的重要催化剂。然而，尽管它们很重要，但在理解社区如何调动这些资产以满足大规模遗产重建的资本和制度要求方面，仍然存在一个关键的理论空白。本研究以尼泊尔帕坦的皮姆巴哈尔池塘地区为例，探讨了2015年廓尔喀地震后社区主导的城市复兴。本研究采用定性方法，并将基于资产的社区发展（ABCD）框架作为基本视角。结果表明，战略相互依存模式是成功振兴的关键，而不是狭隘的地方主义。这种模式促进了一种正式的混合治理结构，使居民、城市当局和国际合作伙伴之间的动态协作成为可能。研究结果表明，这种模式使社区能够利用其文化资产和社会资本来协商和共同管理外部资源。这一进程不仅确保了真正的重建，而且建立了自我维持的财政和社会基础。然而，成功的复兴带来了文化商品化和公共空间争夺的新挑战。本研究的主要贡献在于提出了战略相互依存理论，作为ABCD的必要理论延伸。报告认为，虽然以资产为基础的方法在社区主导的城市复兴中具有巨大潜力，但它们的实施需要仔细考虑权力动态、文化完整性和长期可持续性。最后，本研究有助于了解文化敏感资产的灾后恢复，为城市规划和遗产管理提供可转让的模式，特别是在全球南方。

The built environment significantly influences individuals' propensity to walk, prompting local authorities to allocate financial resources for its improvement. Organisations overseeing the built environment have developed audit tools as standards to evaluate pathways and highlight developments to facilitate active travel. Using these audit tools as a foundation, this study developed 21 walking investment-relevant factors that were embedded into a preference-based elicitation approach known as Best-Worst Scaling (BWS). We report findings from a UK-wide sample of 364 adults aged 18 years or older. Data were analysed using aggregate (counting) and disaggregated (regression) approaches. Both approaches confirmed that footpath provision, footpath condition, lighting, footpath width, and buffer zone were the top-five priority areas for investment. The instrument is transferable across diverse cultural and country contexts, enabling international comparisons and further refinements by academics as well as policy makers.

建筑环境显著影响个人的步行倾向，促使地方当局分配财政资源来改善其状况。监督建筑环境的组织已经开发了审核工具作为评估途径的标准，并强调了促进积极旅行的发展。以这些审计工具为基础，本研究开发了21个与投资相关的动态因素，这些因素被嵌入到基于偏好的启发方法中，称为最佳-最差尺度（BWS）。我们报告了来自全英国364名18岁或以上成年人的调查结果。使用汇总（计数）和分解（回归）方法分析数据。两种方法均证实，行人路供应、行人路状况、照明、行人路宽度和缓冲区是投资的五大优先范畴。该工具可在不同的文化和国家背景下进行转移，使学者和决策者能够进行国际比较和进一步完善。

In the context of the circular economy (CE), promoting sharing practices – within the contexts of mobility, spaces and services – is essential for extending resource use and fostering sustainability in urban environments. However, the ability of urban neighborhoods to effectively integrate shared mobility, spaces and services remains largely unexplored. This study introduces the conceptual framework of resharing, which merges these elements into a cohesive urban strategy. In developing a comprehensive framework, this paper explores the benefits of resharing and examines recent shifts in urban neighborhoods, particularly multifunctional ground floors. The study also analyzes the spatial and contextual conditions that enable or constrain resharing practices in neighborhoods and buildings. A mixed methods approach was used in the study, consisting of spatial observations in Løren – a neighborhood in northeastern Oslo (Norway), a review of planning and building regulations, and the development of a dashboard tool that is designed to measure and visualize reshareability in the built environment. By offering practical insights and analytical tools, this research aims to assist urban planners and policymakers in refining neighborhood planning strategies, thereby ultimately promoting more interconnected, livable and sustainable urban communities.

在循环经济的背景下，在流动性、空间和服务的背景下，促进共享实践对于扩大资源利用和促进城市环境的可持续性至关重要。然而，城市社区有效整合共享交通、空间和服务的能力在很大程度上仍未得到探索。本研究引入了再共享的概念框架，将这些元素融合为一个有凝聚力的城市战略。在开发一个综合框架的过程中，本文探讨了再共享的好处，并考察了城市社区，特别是多功能底层的最新变化。该研究还分析了在社区和建筑中实现或限制再共享实践的空间和环境条件。研究中使用了混合方法，包括在挪威奥斯陆东北部的Løren社区进行空间观测，回顾规划和建筑法规，以及开发仪表板工具，旨在测量和可视化建筑环境中的可共享性。通过提供实用的见解和分析工具，本研究旨在帮助城市规划者和政策制定者完善社区规划策略，从而最终促进更加互联、宜居和可持续的城市社区。

This study introduces an innovative framework for assessing social resilience based on social archetypes, moving beyond traditional methods that often analyse social groups based on socio-economic or socio-demographic factors. By incorporating psychographic dimensions such as individual capacities and perceptions, which are more stable over time than socio-economic or socio-demographic characteristics, our approach aims to identify social archetypes as a tool to uncover nuanced social resilience performance patterns of distinct groups of individuals. Using empirical data from Singapore's working population (n = 2542) and a k-means clustering approach, we identify three distinct archetypes, namely The Optimistic Leaders (27 %, n = 681), The Engaged Connectors (41 %, n = 1047), and The Reserved Individualists (32 %, n = 814) respectively, Each exhibiting distinct social resilience performance patterns under both stable conditions and disruptions. We observe unexpected reactions of social archetypes to (potential) disruptions: archetypes with relatively high social resilience performance levels under normal conditions show statistically significant declines in social cohesion and trust in leaders during crises. In contrast, social archetypes with less pro-social performances in normal times seem to activate latent social resilience performance levels during disruptions, exhibiting statistically significant increases in social networks and social support. Our results suggest that social archetypes matter for social resilience performances within a society and should be considered to design tailored measures for distinct social groups to effectively support and enhance social resilience.

这项研究引入了一个基于社会原型评估社会弹性的创新框架，超越了通常基于社会经济或社会人口因素分析社会群体的传统方法。通过结合个人能力和感知等心理维度，这些维度比社会经济或社会人口特征更稳定，我们的方法旨在确定社会原型，作为揭示不同个体群体微妙的社会弹性表现模式的工具。利用新加坡工作人口（n = 2542）的经验数据和k-means聚类方法，我们分别确定了三种不同的原型，即乐观型领导者（27%,n = 681）、敬业型连接器（41%,n = 1047）和保守型个人主义者（32%,n = 814），每种原型在稳定条件和中断条件下都表现出不同的社会弹性表现模式。我们观察到社会原型对（潜在）破坏的意外反应：在正常情况下具有相对较高社会弹性绩效水平的原型在危机期间的社会凝聚力和对领导者的信任在统计上显着下降。相比之下，在正常情况下亲社会表现较差的社会原型似乎在中断时激活了潜在的社会弹性表现水平，在社会网络和社会支持方面表现出统计学上显著的增加。我们的研究结果表明，社会原型对一个社会的社会弹性表现很重要，应该考虑为不同的社会群体设计量身定制的措施，以有效地支持和增强社会弹性。

Research on healthy city evaluation has grown significantly, yet disparities exist in the conception and scope, applications under diverse urban contexts, and evolving priorities of the key themes; which have hindered broader applicability and cross-regional comparison. Based on an in-depth analysis of 250 international journal articles published between 1986 and 2024, this paper presents a comprehensive review of healthy city evaluation research, for which the development trajectory, temporal evolution, and spatial distribution features are discussed critically, and future research agenda of four components are proposed. Specifically, four development stages were identified to present the evolving dynamics of healthy city evaluation research: Stage I (1986–1991) of Initial exploration; Stage II (1992–2005) of Slow growth and sporadic interest; Stage III (2006–2019) of Expansion and consolidation; and Stage IV (2020–2024) of Post-Pandemic Surge. Key research hotspots and mainstream research methods of each development stages, as well as the evolving trajectories between different development stages were unravelled and discussed. Spatially, via the lens of disparity, the characteristics of healthy city evaluation frameworks between the developed and developing countries were comparatively discussed; and the opportunities for cross-region knowledge exchange and experience sharing are highlighted. On the basis of above analysis, future research agenda of healthy city evaluation research was proposed, including four inter-connected components of conception, indicators, methodology, and governance.

健康城市评价的研究日益增多，但在概念和范围、不同城市背景下的应用、关键主题的优先顺序等方面存在差异；这阻碍了更广泛的适用性和跨区域比较。本文在对1986—2024年国际期刊发表的250篇论文进行深入分析的基础上，对健康城市评价研究的发展轨迹、时间演变和空间分布特征进行了批判性探讨，并提出了健康城市评价的四个组成部分的未来研究议程。具体而言，健康城市评价研究的发展分为四个阶段：第一阶段（1986-1991）：初步探索阶段；第二阶段（1992-2005）增长缓慢，兴趣零星；第三阶段（2006-2019）扩张巩固阶段；以及第四阶段（2020-2024年）大流行后激增。梳理和讨论了各发展阶段的重点研究热点和主流研究方法，以及不同发展阶段之间的演变轨迹。空间上，通过差异视角比较探讨了发达国家与发展中国家健康城市评价框架的特点；并强调了跨区域知识交流和经验分享的机会。在上述分析的基础上，提出了健康城市评价研究的未来研究议程，包括概念、指标、方法和治理四个相互关联的组成部分。

Identifying urban agglomeration's range: Integrating clustering and accessibility analysis 城市群范围识别：聚类与可达性分析的整合

Urban agglomerations (UAs) play an important role in China's socio-economic development. Accurate identification of UAs' range is vital to optimising spatial patterns and promoting co-ordinated regional development. However, existing studies have focused primarily on constructing single-dimensional indicators, with insufficient exploration of the integrity and cross-regional applicability of the indicator system. To fill this gap, we proposed a ‘cluster + accessibility’ framework with an application in the Central Yunnan Urban Agglomeration (CYUA). Based on three core aspects (cluster degree, connectivity, and accessibility) and three spatial dimensions (core, periphery, and radiation), we constructed a comprehensive quantitative identification technology system. Compared with existing research, this study identified the specific administrative areas included in the CYUA (including its core, peripheral, and radiation areas), covering a total of 22 counties and districts. From 2014 to 2022, the CYUA expanded, with its peripheral area moving southwards and northwards and its radiation area extending eastwards. In addition, the study showed that different indicators had significant differences in the applicability of UA range identification. Economic density, ratio of non-agricultural output, night-time light, and ratio of impervious surface area exhibited significant spatial clusters, making them suitable for identifying the CYUA's core area. This framework makes up for the lack of integrity in the index system's construction, and improves the cross-regional applicability of UA identification.

城市群在中国社会经济发展中发挥着重要作用。准确识别无人机的范围对优化空间格局、促进区域协调发展至关重要。然而，现有的研究主要集中在构建单一维度的指标，对指标体系的完整性和跨区域适用性的探索不足。为了填补这一空白，我们提出了一个“集群+可达性”的框架，并在滇中城市群（CYUA）中应用。基于集群度、连通性、可达性三个核心维度和核心、外围、辐射三个空间维度，构建了综合定量识别技术体系。与已有研究相比，本研究确定了CYUA所包括的具体行政区域（包括其核心区、外围区和辐射区），共覆盖22个县区。2014年至2022年，中心外围区域向南、向北移动，辐射区域向东延伸。此外，研究表明，不同指标对UA范围识别的适用性存在显著差异。经济密度、非农业产出比、夜间光照和不透水面积比呈现出显著的空间集聚性，适合作为该区核心区的识别指标。该框架弥补了指标体系构建完整性的不足，提高了UA识别的跨区域适用性。

Silently ageing, quietly shrinking: Examining age-friendly policy in French and Canadian shrinking cities 无声的老龄化，无声的萎缩：审视法国和加拿大萎缩城市的老年人友好政策

The populations of cities across the world are ageing. Many demographically older communities face spatially and economically related obstacles, such as shrinking populations and economic decline. This is the case in France and Canada, where, despite having very different urban landscapes, geographies of shrinking and ageing cities are similar. In both countries, population shrinkage is prominent, yet widely overlooked by the media and general public and ignored by politicians and decision makers. The paucity of consideration of shrinking cities combined with the shift of the world's (Canada) and Europe's (France) largest proportional baby boom generations into older adulthood present a clarion call for academics, planners, and policymakers. First, our research examined the past and present geographies of ageing and shrinking in Canada and France and determined that cities experiencing severe population shrinkage are likely to experience higher rates of ageing. Migration behaviours by age were found to vary based on the percentage of older adults in the city, and whether the city was growing or shrinking. Second, we analyzed age-friendly urban policy documents and found that shrinking, ageing cities were seldom members of the World Health Organization's Age-friendly Cities network. Of the few cities that were members of the network and had developed age-friendly policy documents, none had policies referring to population shrinkage. Global age-friendly policy documents also did not account for population decline. The findings demonstrate the need for planners and policymakers to address the unique context created by simultaneous demographic ageing and population decline.

世界各地的城市人口都在老龄化。许多人口老龄化社区面临着与空间和经济有关的障碍，如人口减少和经济衰退。法国和加拿大的情况就是如此，尽管两国的城市景观非常不同，但萎缩和老龄化城市的地理位置相似。在这两个国家，人口萎缩都很突出，但却被媒体和公众普遍忽视，被政治家和决策者忽视。人们对不断缩小的城市缺乏考虑，再加上世界（加拿大）和欧洲（法国）婴儿潮时期人口比例最大的几代人步入老年，这给学者、规划者和政策制定者发出了响亮的呼声。首先，我们的研究考察了加拿大和法国过去和现在人口老龄化和人口萎缩的地理分布，并确定经历严重人口萎缩的城市可能会经历更高的老龄化率。研究发现，按年龄划分的移民行为根据城市中老年人的比例以及城市是在增长还是在萎缩而有所不同。其次，我们分析了老年人友好型城市政策文件，发现萎缩、老龄化的城市很少是世界卫生组织老年人友好型城市网络的成员。在为数不多的加入该网络并制定了有利于老年人的政策文件的城市中，没有一个城市制定了涉及人口萎缩的政策。全球老年人友好政策文件也没有考虑到人口下降。研究结果表明，规划人员和政策制定者需要解决人口老龄化和人口下降同时造成的独特背景。

Urban shrinkage is a hot topic in current research, and the academic community has engaged in extensive discussions on its formation mechanisms. However, as a new driving force for reshaping the urban pattern, the spatial effect and nonlinear influence mechanism of the digital economy (DE) on urban shrinkage have not received sufficient attention and urgently need further exploration. This paper takes 282 prefecture-level cities in China from 2011 to 2021 as research samples, constructing the spatial Durbin model and the threshold regression model to empirically analyze the spatial spillover effect and nonlinear influence mechanism of DE on urban shrinkage. The results show that DE has a significant promotional effect on local urban shrinkage and has a significant positive spatial spillover effect on neighboring urban shrinkage. This influence shows significant regional heterogeneity. Specifically, the direct effects in the eastern and central regions are the most significant, the spatial spillover effect in the eastern region is the most prominent, while the direct and indirect influences in the western and northeastern regions are not significant. Finally, the impact of DE on urban shrinkage shows a significant single threshold effect, with a U-shaped nonlinear relationship between the two. In the initial stage, DE can alleviate urban shrinkage, but once its development exceeds a certain threshold, it begins to catalyze urban shrinkage. The research conclusions contribute to a deeper understanding of the spatial effects of DE and provide theoretical support and policy recommendations for the digital transformation of shrinking cities and regional coordinated development.

城市收缩是当前研究的热点，学界对其形成机制进行了广泛的探讨。然而，作为重塑城市格局的新动力，数字经济对城市收缩的空间效应和非线性影响机制尚未得到足够重视，亟待进一步探索。本文以2011 - 2021年中国282个地级市为研究样本，构建空间Durbin模型和阈值回归模型，实证分析DE对城市收缩的空间溢出效应和非线性影响机制。结果表明：DE对局部城市收缩具有显著的促进作用，对邻近城市收缩具有显著的正向空间溢出效应。这种影响表现出显著的区域异质性。其中，东部和中部地区的直接效应最为显著，东部地区的空间溢出效应最为突出，而西部和东北地区的直接和间接影响都不显著。DE对城市收缩的影响表现出显著的单阈值效应，两者呈u型非线性关系。在初始阶段，DE可以缓解城市收缩，但一旦其发展超过一定阈值，它就开始催化城市收缩。研究结论有助于深入理解数字化转型的空间效应，为收缩型城市数字化转型和区域协调发展提供理论支持和政策建议。

This study investigates how pervasive games can engender and shape relationships with urban spaces, using as a case study the Walklets game experience in the neighborhoods of Is Mirrionis and San Michele in Cagliari (Italy). Walklets is a mobile based, narrative-driven pervasive game designed to encourage exploration and engagement with real-world environments. Through a mixed-methods approach combining pre-, post-, and follow-up surveys and thematic qualitative analysis, we assess the effects on several psychological variables: restoration, engagement, serendipity, emotions, and creativity. Findings show that Walklets had a significant positive impact on participants' perception and interpretation of the urban environment, enhancing emotional engagement, spatial awareness, and cognitive appreciation of places. Although some effects diminished over time, the qualitative data reveal long lasting mnestic traces and shifts in participants' relationship with the neighborhood. The study highlights the importance of narrative immersion, serendipitous discovery, and historical context in shaping meaningful experiences of urban places. We argue that pervasive games like Walklets can serve as tools for reimagining, learning about, and emotionally connecting with urban environments, offering new modes of experiencing the city.

本研究以意大利卡利亚里Is Mirrionis和San Michele社区的Walklets游戏体验为例，调查了无处不在的游戏如何产生和塑造与城市空间的关系。Walklets是一款基于手机的故事驱动游戏，旨在鼓励探索和参与现实世界的环境。通过将事前、事后和后续调查以及专题定性分析相结合的混合方法，我们评估了对几个心理变量的影响：恢复、参与、意外发现、情绪和创造力。研究结果表明，步行对参与者对城市环境的感知和解读产生了显著的积极影响，增强了参与者的情感参与、空间意识和对场所的认知欣赏。虽然一些影响随着时间的推移而减弱，但定性数据显示，参与者与邻居的关系存在持久的遗忘痕迹和转变。该研究强调了沉浸式叙事、偶然发现和历史背景在塑造城市场所有意义体验中的重要性。我们认为，像Walklets这样的普及游戏可以作为重新想象、学习和与城市环境建立情感联系的工具，提供体验城市的新模式。

Urban high temperatures are increasingly severe, significantly impacting public health and quality of life. Spatial interactions amplify individuals' exposure to high temperatures, thereby heightening the risk of heat-related hazards. Mobile populations, in contrast to static indoor populations, often demand greater attention from urban managers. However, widespread cooling interventions can lead to increased costs and resource inefficiencies. This study addresses these challenges in three key steps. First, we utilize mobile phone data to extract spatial interaction behaviors and mobility intensities of populations at various times. Second, we develop a novel heat exposure risk assessment framework by integrating the concept of crowd activity intensity into the existing heat exposure model. Lastly, we apply this framework to Shenzhen's Futian District to generate heat exposure risk maps for different times of the day. The study reveals the following key findings: (1) Significant variations in land surface temperatures, particularly in urban core areas where high building density and concentrated human activities exacerbate heat island effects. (2) The spatial gravity model quantifies crowd activity intensity, illustrating population movement and activity distribution across Futian District, which is critical for understanding heat exposure risks. The intensity of human activity demonstrates a trend of shifting from north to south, with a primary concentration in the central areas. (3) The heat exposure risk assessment model, based on functional zone delineation, highlights significant differences in risk levels among zones during high-temperature periods. For instance, Zones B and C (Xiangmi Lake New Financial Center and Futian Central District) exhibit higher risks between 12:00 PM and 5:00 PM, whereas Zone A (Meilin Living Circle) shows elevated risks during peak residential activity times, from 6:00 AM to 9:00 AM. These variations are closely related to the functional orientation of each zone. The findings of this study provide valuable insights for decision-makers, enabling more effective and efficient heat risk management through time-segmented strategies tailored to different functional zones and population dynamics.

城市高温日益严重，严重影响公众健康和生活质量。空间相互作用扩大了个体对高温的暴露，从而增加了与热有关的危害的风险。与静止的室内人口相比，流动人口往往需要城市管理者给予更多的关注。然而，广泛的冷却干预措施可能导致成本增加和资源效率低下。本研究通过三个关键步骤解决了这些挑战。首先，利用手机数据提取不同时段人群的空间交互行为和流动强度。其次，我们将人群活动强度的概念整合到现有的热暴露模型中，建立了一个新的热暴露风险评估框架。最后，我们将此框架应用于深圳福田区，生成一天中不同时间的热暴露风险图。研究发现：(1)地表温度变化显著，特别是在建筑密度高、人类活动集中的城市核心区，热岛效应加剧。(2)空间重力模型量化了人群活动强度，反映了福田区人口流动和活动分布，对了解热暴露风险具有重要意义。人类活动强度呈现由北向南转移的趋势，主要集中在中部地区。(3)基于功能区划分的热暴露风险评价模型在高温时期各功能区风险水平存在显著差异。例如，B区和C区（香蜜湖新金融中心和福田中心区）在中午12点到下午5点之间风险较高，而A区（美林生活圈）在上午6点到9点的住宅活动高峰时段风险较高。这些变化与各功能区的功能定位密切相关。本研究结果为决策者提供了有价值的见解，通过针对不同功能区和人口动态的分时策略，实现更有效和高效的热风险管理。
