Soundscapes significantly impact human well-being, yet standard Western-based Soundscape Affective Quality (SAQ) scales may not accurately represent culturally specific perceptions. This study explored structural differences in soundscape emotional experiences between Chinese and Western cultures using an indigenous approach. An Indigenous Chinese SAQ (ICSAQ) scale was developed through perceptual evaluations of 132 representative Chinese soundscape excerpts by 264 participants from 30 provinces, employing 108 culturally relevant descriptors. Principal component analysis revealed two dimensions-Comfort and Richness-differing notably from the global Pleasantness-Eventfulness model. Comparison with the translated global SAQ scale showed significant measurement bias, with the imported scale overestimating positive emotions and activation levels. Regression analyses confirmed the ICSAQ scale's stronger interpretability regarding objective acoustic indicators. The findings highlight critical limitations of translation-based environmental affective measurements, emphasizing the necessity of culturally appropriate assessment tools for inclusive urban environmental management.

音景显著地影响着人类的幸福感，然而标准的基于西方的音景情感质量（SAQ）量表可能不能准确地代表特定文化的感知。本研究采用本土视角探讨了中西方文化在音景情感体验上的结构性差异。本研究采用108个文化相关描述词，对来自30个省份的264名被试的132个具有代表性的中国声景片段进行感知评价，并编制了一份中国本土声景质量量表。主成分分析揭示了两个维度——舒适度和丰富性——与全球愉悦-事件性模型明显不同。与翻译后的全球SAQ量表比较显示出显著的测量偏差，进口量表高估了积极情绪和激活水平。回归分析证实了ICSAQ量表在客观声学指标方面具有较强的可解释性。研究结果强调了基于翻译的环境情感测量的关键局限性，强调了文化上适当的评估工具对包容性城市环境管理的必要性。

Temporal dynamics remain an understudied aspect of nature-based solutions (NBS) literature, particularly in relation to public preferences. This study introduces the concept of NBS temporal effectiveness, defined as the ability of NBS to provide co-benefits over short, medium, and long terms with varying intensities, as perceived by urban residents. Specifically, we investigated the potential conflicts in the temporal effectiveness in Trento, Italy, through a public participation GIS (PPGIS) approach (n = 286). Our findings reveal that the intensity and directionality of conflict change across short, medium and long-term NBS, respondent groups, and the spatial context of implementation. Contrary to the common perception that immediate solutions are always preferred, NBS with long-term effectiveness can gain significant public support, particularly when they demonstrate greater benefits than short-term alternatives. This study contributes to the NBS literature by being the first to explore the concept of temporal effectiveness and its implications for public preferences, demonstrating that considerations regarding temporalities must be made when planning NBS interventions, as conflicts may arise in relation to interventions with different temporal effectiveness.

时间动态仍然是基于自然的解决方案（NBS）文献中研究不足的一个方面，特别是与公众偏好有关的方面。本研究引入了国家统计局时间有效性的概念，将其定义为城市居民所感知的国家统计局在短期、中期和长期提供不同强度的共同利益的能力。具体而言，我们通过公众参与GIS （PPGIS）方法（n = 286）调查了意大利特伦托市时间有效性中的潜在冲突。我们的研究结果揭示了冲突的强度和方向性在短期、中期和长期国家统计局、被调查者群体和实施的空间背景中发生变化。与人们普遍认为的立即解决方案总是更受欢迎相反，具有长期有效性的国家统计局可以获得大量公众支持，特别是当它们显示出比短期替代方案更大的好处时。本研究首次探讨了时间有效性的概念及其对公众偏好的影响，为NBS文献做出了贡献，表明在规划NBS干预措施时必须考虑到时间性，因为具有不同时间有效性的干预措施可能会产生冲突。

We examine the differences in meteorological output from the Weather Research and Forecasting (WRF) model run at 270 m horizontal resolution using 10 m, 100 m and 1 km resolution 3D neighborhood morphological inputs and with no morphological inputs. We find that the spatial variability in temperature, humidity, and other meteorological variables across the city can vary with the resolution and the coverage of the 3D urban morphological input, and that larger differences occur between simulations run without 3D morphological input and those run with some type of 3D morphology. We also find that the inclusion of input-building-defined roughness length calculations would improve simulation results further. We show that these inputs produce different patterns of heat wave spatial heterogeneity across the city of Washington, DC. These findings suggest that understanding neighborhood level urban sustainability under extreme heat waves, especially for vulnerable neighborhoods, requires attention to the representation of surface terrain in numerical weather models.

我们研究了在270米水平分辨率下运行的天气研究与预报（WRF）模式，使用10米、100米和1公里分辨率的3D邻域形态输入和不使用形态输入的气象输出的差异。研究发现，城市温度、湿度等气象变量的空间变异性会随着城市三维形态输入的分辨率和覆盖范围的不同而发生变化，并且在没有三维形态输入的模拟与具有某种三维形态输入的模拟之间差异更大。我们还发现，包含输入构建定义的粗糙度长度计算将进一步改善模拟结果。我们表明，这些输入在整个华盛顿特区产生了不同的热浪空间异质性模式。这些发现表明，要理解极端热浪下社区层面的城市可持续性，特别是对脆弱社区而言，需要注意数值天气模式中地表地形的表示。

New migrant populations in rapidly growing cities globally are often socially and politically marginalized, limiting their potential to contribute to the positive transformation of urban futures. Such marginalisation can potentially be overcome through deliberate efforts to build empathy between groups. Here we apply insights on empathic action to planning processes with the aim of diversifying planning processes to provide plural perspectives on risk and sustainability and giving marginalised groups opportunities to shape key decisions. We report on action research to examine whether empathic connection between urban planners and new migrant populations leads to processes that enhance and integrate new voices and perspectives. The intervention involved photo-elicitation interviews, focus groups and perspective exchange workshops over eighteen months of intensive engagement in Chattogram, Bangladesh. The findings demonstrate that empathy for diverse social groups has practical implications for sustainability where individuals have agency and feel empowered to enhance each other’s wellbeing.

在全球快速发展的城市中，新的移民人口往往在社会和政治上被边缘化，限制了他们为城市未来的积极转变做出贡献的潜力。这种边缘化有可能通过有意识地努力在群体之间建立同理心来克服。在这里，我们将移情行动的见解应用于规划过程，目的是使规划过程多样化，为风险和可持续性提供多元视角，并为边缘化群体提供塑造关键决策的机会。我们报告了一项行动研究，以检查城市规划者和新移民人口之间的共情联系是否会导致增强和整合新声音和观点的过程。干预措施包括在孟加拉国Chattogram进行为期18个月的密集参与，包括拍照采访、焦点小组和观点交流讲习班。研究结果表明，对不同社会群体的同理心对可持续发展具有实际意义，在这种可持续发展中，个人拥有能动性，并感到有能力增强彼此的幸福感。

Global digitalization leads to a new digital inequality, jointly faced by urban and rural areas. Diagnosing these digital challenges and seeking common coping strategies are crucial in the digital era. Yet, the state of Urban-Rural Digitalization (URD) remains ambiguous, and effective solutions are still lacking. Here we propose an integrative approach and introduce a novel Development-Gap-Integration framework to assess URD. Utilizing authoritative data from official government sources and institutes, we conduct a comprehensive analysis of 30 provinces in China from 2000 to 2020. Our findings depict a transformative journey of URD, evolving from divide to inclusion. The increasing integration accompanies by advancing development and diminishing gaps. However, we identify three significant challenges: 1) high development coinciding with high gaps, 2) inadequate integration of digital applications, and 3) widening disparity between provinces. Thus, we suggest tailored policy recommendations focused on urban-rural integration, enhancing digital literacy, and promoting regional coordinated development.

全球数字化导致城市和农村地区共同面临新的数字不平等。诊断这些数字挑战并寻求共同的应对策略在数字时代至关重要。然而，城乡数字化（URD）的现状依然模糊不清，仍然缺乏有效的解决方案。在此，我们提出了一种综合方法，并引入了一个新颖的 "发展-差距-整合 "框架来评估 URD。利用来自政府官方来源和研究机构的权威数据，我们对中国 30 个省份从 2000 年到 2020 年的情况进行了全面分析。我们的研究结果描绘了城市发展的转型历程，即从分化到融合的演变过程。随着发展的推进和差距的缩小，融合度也在不断提高。然而，我们也发现了三个重大挑战：1）高发展与高差距并存；2）数字应用整合不足；3）省际差距不断扩大。因此，我们提出了以城乡一体化、提升数字素养、促进区域协调发展为重点的针对性政策建议。

Transportation infrastructures often impose a rigid and controlled formation over the organic dynamism of urban areas. This blend of infrastructure and urban context redefines transportation systems beyond their purely functional roles, creating opportunities for new land uses, social interactions in the spaces beneath them. The management and adaptation of these urban void spaces under elevated infrastructure can become either assets or liabilities, particularly under the unique conditions prevalent in the Global South Megacities. Using participatory action research datasets and zoning models, this study explores the spatial relationships between physical infrastructure and its contextually accommodating opportunities. This article highlights how the squatter community under the Tejgaon-Nabisco Flyover in Dhaka, Bangladesh, autonomously organizes and utilizes these spaces, fostering adaptive place-making and developing local economic practices supported by the flyover’s structural elements.

交通基础设施通常会对城市地区的有机活力强加一种僵硬和受控的形式。这种基础设施与城市环境的融合重新定义了交通系统，使其超越了纯粹的功能性作用，为新的土地用途、其下空间的社会互动创造了机会。高架基础设施下的这些城市空隙空间的管理和适应既可以成为资产，也可以成为负债，尤其是在全球南部特大城市普遍存在的独特条件下。本研究利用参与式行动研究数据集和分区模型，探讨了有形基础设施与其环境适应机会之间的空间关系。本文重点介绍了孟加拉国达卡 Tejgaon-Nabisco 立交桥下的棚户区如何自主组织和利用这些空间，在立交桥结构元素的支持下，促进适应性场所营造并发展当地经济实践。

It is well-documented that people of color in the U.S. are disproportionately exposed to extreme urban heat. However, most studies have focused on large cities for one point in time, and less is known about how heat exposure changes over time in smaller cities. Here, we present a study of the changing nature of urban heat exposure and cooling strategies for ten cities in Connecticut in the U.S. Our results show that people of color experience more heat exposure and fewer adaptation strategies. They experienced higher overall temperatures, more extremely hot days, and larger increases in heat exposure. Also, they have lower air conditioning ownership rates and lower tree cover. Taken together, the results indicate that people of color are not only exposed to higher temperatures but also disproportionately exposed to increasing temperatures over time. With lower heat adaptation capacity, people of color are more vulnerable to increasing urban heat.

美国有色人种过多地暴露在城市极端高温环境中，这是有据可查的。然而，大多数研究都集中在大城市的某个时间点上，对小城市的高温暴露如何随时间变化知之甚少。我们的研究结果表明，有色人种暴露在高温下的时间更长，采取的适应策略更少。他们经历了更高的总体气温、更多的酷热天以及更大幅度的高温暴露。此外，他们的空调拥有率较低，树木覆盖率也较低。综合来看，这些结果表明有色人种不仅暴露在较高的温度下，而且还不成比例地暴露在随着时间推移而不断升高的温度下。由于热适应能力较低，有色人种更容易受到城市高温的影响。

Adopting Circular Economy practices in the construction industry can help reduce greenhouse gas emissions. However, many barriers exist to adoption, and current perceptions of and willingness to pay for circularity have yet to be quantified. This study seeks to understand the various perceptions of circularity in the construction industry, characterize uncertainties and risks, and identify economic incentives and opportunities that could accelerate circular adoption via an industry survey of three stakeholder groups. 58 stakeholders filled out part of the survey, and 42 stakeholders completed the majority of questions. Real estate developers are willing to pay an average premium of 10% for construction costs if there’s a minimum embodied carbon reduction of 53%. Design and construction professionals and material suppliers were also surveyed. Reasons for adopting circular practices were primarily driven by client, design team, and net zero goals. The results of this survey begin to characterize the economic landscape of what is needed for a circular transition in the built environment.

在建筑行业采用循环经济做法有助于减少温室气体排放。然而，在采用过程中存在许多障碍，目前对循环经济的认识和支付意愿也有待量化。本研究旨在通过对三个利益相关者群体进行行业调查，了解建筑行业对循环经济的各种看法，确定不确定因素和风险，并找出可加快采用循环经济的经济激励措施和机会。58 个利益相关者填写了部分调查问卷，42 个利益相关者填写了大部分问题。如果体现碳排放量至少减少 53%，房地产开发商愿意支付平均 10%的建筑成本溢价。设计和建筑专业人士以及材料供应商也接受了调查。客户、设计团队和净零目标是采用循环做法的主要原因。这项调查结果表明，在建筑环境中实现循环转型所需的经济条件已初见端倪。

Over the past two decades, research promoting a sustainable built environment has pioneered new horizons to accelerate the transition to a circular economy. Yet, these efforts are suffering from a significant theory-practice divide. This article offers three interconnected research themes to bridge this gap: 1. Distinguishing circularity practices across spatial and time scales; 2. Redesigning the value of design and its process; and 3. Learning from sister transitions for acceleration.

在过去二十年里，促进可持续建筑环境的研究为加速向循环经济过渡开辟了新天地。然而，这些努力在理论与实践之间存在着巨大的鸿沟。本文提出了三个相互关联的研究主题，以弥合这一鸿沟：1.区分不同空间和时间尺度的循环性实践；2.重新设计设计的价值及其过程；3.从姊妹转型中学习以加速转型。从姊妹转型中学习加速。
