This article scrutinizes a Soviet nuclear industry's urban settlement from the perspective of this industry's endpoints. It approaches the nuclear industry's endpoints both in the register of city-enterprise relations and in the register of the spatio-temporal and institutional reality of the Cold War. The article's argument rests on empirical research of urban development after nuclear power in the town of Visaginas in Lithuania, a satellite of the Ignalina Nuclear Power Plant (INPP). Today Visaginas is in the process of disentangling itself from the USSR's strategic Cold War exclusive nuclear industry network. I single out and reflect on three units of analysis of this disentanglement – biography, site, and schedule. By documenting the modes of spatiality and of temporality produced by urban-nuclear entanglements, I challenge the application of the notion of ‘de-industrialization’ to phasing out nuclear power plants. I show that nuclear technology has given rise to a type of industrial site and to Cold War modernity as a spatio-temporal and institutional reality, which have no intelligible endpoints. Despite the unintelligibility of Cold War modernity's endpoints, nuclear settlements serve as explorers of the institutional and infrastructural hyper- long-term, and therefore they nurture diachronic solidarity via a diachronic division of labor.
本文从苏联核工业终点的角度出发,对该工业的城市定居点进行了研究。文章既从城市与企业关系的角度,也从冷战的时空和制度现实的角度来探讨核工业的终点。文章的论点基于对立陶宛维萨吉纳斯镇核电后城市发展的实证研究,该镇是伊格纳利纳核电厂(INPP)的卫星城。如今,维萨吉纳斯正处于脱离苏联冷战时期排他性战略核工业网络的过程中。我将这一脱钩的三个分析单元--传记、现场和时间表--单独列出并进行思考。通过记录城市与核的纠葛所产生的空间性和时间性模式,我对将 "去工业化 "概念应用于逐步淘汰核电站的做法提出了质疑。我指出,核技术催生了一种类型的工业基地,也催生了作为时空和制度现实的冷战现代性,而这些都没有可理解的终点。尽管冷战现代性的终点是不可理解的,但核聚落是制度和基础设施超长期性的探索者,因此它们通过非同步分工促进了非同步团结。

Peri-Urban Landscapes (PULs) are transitional areas composed of a mix of natural and anthropogenic land covers. The unsustainable character of many PULs is widely recognised, but their governance is particularly challenging. The paper moves from the hypothesis that addressing some of the sustainability challenges of PULs requires the combination of multiple Policy Instruments (PIs), i.e., a policy mix. An online survey was developed to collect cases of PULs governance with a twofold purpose: i) to identify and describe existing PIs implemented in PULs, and ii) to investigate which combinations of PIs are adopted to address specific categories of sustainability challenges. Fifty valid answers describing 47 cases of PULs governance from 26 countries were collected and analysed. The results confirm the presence of a policy mix approach, suggesting the need for a plurality of PIs to govern the dynamics and complexities of PULs. Moreover, the results indicate an important role of the regional governance level, a dominating presence of top-down instruments, and a need for more effective inclusion of citizens into policy-making processes related to PULs. A reflection on the findings considering the existing literature on governance experimentation suggests governance mixes for PULs as potential approaches to address some of the shortcomings of the analysed policy mixes.
城市周边景观(PULs)是由自然和人为土地覆盖混合组成的过渡区域。许多 PULs 的不可持续特征已得到广泛认可,但其治理尤其具有挑战性。本文提出的假设是,要解决 PULs 面临的一些可持续性挑战,需要将多种政策工具 (PI) 结合起来,即政策组合。为了收集 PULs 治理案例,我们开展了一项在线调查,目的有二:i) 识别并描述 PULs 中实施的现有 PI;ii) 调查采用哪些 PI 组合来应对特定类别的可持续性挑战。收集并分析了 26 个国家 47 个 PULs 治理案例的 50 份有效答案。结果证实了政策组合方法的存在,表明有必要采用多元化的 PI 来治理 PULs 的动态性和复杂性。此外,研究结果还表明,地区治理水平发挥着重要作用,自上而下的手段占主导地位,需要更有效地将公民纳入与 PULs 相关的决策过程。考虑到有关治理试验的现有文献,对研究结果的反思表明,PULs 的治理组合是解决所分析的政策组合的某些缺陷的潜在方法。

Return migrant workers' entrepreneurial choices hinge on the comparative advantages between their origin and destination cities. However, prior research has predominantly concentrated on the economic environment solely within migrant workers' origin cities, disregarding the dual impact of both origins and destinations on return entrepreneurship. This study aims to elucidate how the comparative advantages between origin and destination cities affect the behavior of return migrant workers' entrepreneurship, focusing on the paired relationships formed by these cities as a result of the emergence of return migrant workers' entrepreneurship. To this end, this study leverages data from the 2018 China Labor Force Dynamics Survey (CLDS) and the 2018 China City Statistical Yearbook, and utilizes the network MRQAP regression and network OLS regression methods. The findings highlight that migrant workers exhibit a stronger propensity to return for entrepreneurship when their origin cities possess greater comparative advantages in terms of economic development, employment status, standard of living, and entrepreneurial environments compared with their destination cities. Additionally, the heightened activity and significance of origin cities relative to destination cities in regard to economic growth rate, medical resources, and enterprise R&D investment correspond to a higher likelihood of migrant workers returning for entrepreneurship. These outcomes inform the development of theories related to population migration, and shed light on the relationship between return migrant workers' entrepreneurial endeavors and the regional disparities in economic development.
返乡农民工的创业选择取决于其原籍城市和目的地城市之间的比较优势。然而,以往的研究主要集中于农民工原籍城市的经济环境,忽视了原籍城市和目的地城市对返乡创业的双重影响。本研究旨在阐明原籍城市和目的地城市之间的比较优势如何影响返乡农民工的创业行为,重点关注这些城市因返乡农民工创业的出现而形成的配对关系。为此,本研究利用2018年中国劳动力动态调查(CLDS)和2018年中国城市统计年鉴的数据,采用网络MRQAP回归和网络OLS回归方法。研究结果表明,与目的地城市相比,当原籍城市在经济发展、就业状况、生活水平和创业环境等方面具有更大的比较优势时,农民工表现出更强的返乡创业倾向。此外,与目的地城市相比,原籍城市在经济增长率、医疗资源和企业研发投资方面的活跃程度和重要性更高,这也意味着农民工返乡创业的可能性更大。这些结果为人口迁移相关理论的发展提供了参考,并揭示了返乡农民工的创业努力与地区经济发展差距之间的关系。

Urban Digital Twins (UDTs) offer a promising avenue for advancing sustainable urban development by mirroring physical environments and complex urban dynamics. Such technology enables urban planners to predict and analyze the impacts of various urban scenarios, addressing a global priority for sustainable urban environments. However, their potential in public engagement for environmental perception remains unfulfilled, with existing research lacking the capability to analyze urbanscapes' visual features and predict public perceptions based on photo-realistic renderings. To fill the gap, our study developed and implemented a UDT platform designed for the dual purposes of objective feature evaluation and subjective visual perception, alongside the prediction of perceptions in simulated scenarios. We incorporated DeepLabV3, a deep learning model for imagery semantic segmentation, to quantify a series of visual features within the built environment, such as the proportion of vegetation and architectural elements. Subjective visual perceptions (e.g. safety and lively) are captured using immersive virtual reality to gather public perceptions of different scenarios and learn patterns. Further, utilizing a photo-realistic rendering engine, high-quality renderings of textures and materials for UDT were achieved, and we proved their veracity based on a perception experiment. Afterwards, we employ the random forest algorithm for automated perception predictions of rendering scenarios. The implementation was demonstrated with a case study on an urban greenway in the central area of Singapore. We compared both the objective evaluation and subjective perception results, followed by a demonstration of automated visual perception prediction through photo-realistic scenario simulations, such as modifying vegetation density or introducing new architectural elements to the skyline, to predict the perception of scenarios before they are built, leading to more efficient and automated urban planning.
城市数字孪生体(UDTs)通过镜像物理环境和复杂的城市动态,为推进城市可持续发展提供了一个前景广阔的途径。这种技术使城市规划者能够预测和分析各种城市情景的影响,从而解决全球可持续城市环境的首要问题。然而,这些技术在公众参与环境感知方面的潜力仍未得到发挥,现有研究缺乏分析城市景观视觉特征的能力,也无法根据照片效果图预测公众感知。为了填补这一空白,我们的研究开发并实施了一个 UDT 平台,旨在实现客观特征评估和主观视觉感知的双重目的,同时预测模拟场景中的感知。我们将用于图像语义分割的深度学习模型 DeepLabV3 纳入其中,以量化建筑环境中的一系列视觉特征,如植被和建筑元素的比例。利用沉浸式虚拟现实技术捕捉主观视觉感知(如安全性和生动性),以收集公众对不同场景的感知并学习模式。此外,我们还利用逼真的渲染引擎,为无损检测实现了高质量的纹理和材料渲染,并通过感知实验证明了其真实性。之后,我们采用随机森林算法对渲染场景进行自动感知预测。我们以新加坡中部地区的一条城市绿道为案例进行了演示。我们比较了客观评价和主观感知结果,随后通过照片逼真的场景模拟演示了自动视觉感知预测,例如修改植被密度或在天际线上引入新的建筑元素,从而在场景建成之前预测其感知,从而实现更高效、更自动化的城市规划。

Predevelopment revolving loan funds (PDRLFs) are pools of money from which loans are made and to which loan repayments flow in. They are a part of revolving loan funds (RLFs) that are extensively used in the US to support small businesses and housing. However, PDRLFs' use for funding affordable housing is little-studied. This paper begins to fill this research gap through a literature review and case studies to better understand the key features and the ways to strengthen affordable housing-focused PDRLFs. Finally, it suggests key strategies to strengthen them further, which include flexible funding by the state and federal governments to seed and recapitalize the funds, the need to proactively seek target loan recipients and support them, balance loan applicants' needs with lending efficiency, and view predevelopment in the context of the entire housing finance process.
开发前循环贷款基金(PDRLFs)是一个资金池,贷款从这里发放,还款从这里汇入。它们是循环贷款基金(RLFs)的一部分,RLFs 在美国被广泛用于支持小型企业和住房。然而,对 PDRLFs 用于资助经济适用房的研究却很少。本文通过文献综述和案例研究开始填补这一研究空白,以更好地了解以经济适用房为重点的 PDRLF 的主要特点和加强方法。最后,本文提出了进一步加强这些基金的关键策略,其中包括由州和联邦政府提供灵活的资金,为基金提供种子资金和资本重组资金;需要积极主动地寻找目标贷款接受者并为其提供支持;平衡贷款申请人的需求与贷款效率;以及在整个住房融资过程中看待前期开发。

Over the past decades, numerous European rural regions have witnessed a decline in population, accompanied by the loss of essential services, including financial services. This study examines the dynamic interplay of these processes in the comarcas (counties) of Aragon, Spain. Utilizing a panel dataset at the comarca level and a combination of multivariate statistical techniques, we investigate how sociodemographic and economic profiles interact with financial exclusion arising from the absence or scarcity of bank branches. The absence of bank branches and the saturation of the remaining depend on the evolution of economic dynamism, the ageing process, and the percentage of foreign population. Our findings have allowed us to discern that there are differences between comarcas. Specifically, we have identified three groups, which must face different problems with respect to the lack or scarcity of bank branches, as well as depopulation. This segmentation provides a detailed view of the regional reality and lays the groundwork for more precise and effective intervention strategies, highlighting the potential of comarca capitals as hubs for centralized banking services. This approach optimizes the use of limited resources and enhances the prospects for promoting sustainable development in Aragon and other rural regions of Europe.
在过去的几十年里,欧洲许多农村地区都出现了人口减少的现象,与此同时,包括金融服务在内的基本服务也在流失。本研究探讨了这些过程在西班牙阿拉贡 Comarcas(县)的动态相互作用。我们利用 comarca 层面的面板数据集,并结合多元统计技术,研究了社会人口和经济概况如何与因银行网点缺失或稀缺而产生的金融排斥相互作用。银行网点的缺失和剩余网点的饱和取决于经济活力的发展、老龄化进程和外来人口的比例。我们的研究结果表明,不同的社区之间存在差异。具体来说,我们确定了三个群体,它们必须面对银行网点缺乏或稀缺以及人口减少等不同问题。通过这种划分,我们可以详细了解该地区的实际情况,并为制定更精确、更有效的干预战略奠定基础,同时凸显出 comarca 首府作为集中银行服务枢纽的潜力。这种方法优化了有限资源的使用,增强了促进阿拉贡和欧洲其他农村地区可持续发展的前景。

Dissecting the multiplicity of urban resistance: The Dakota Crescent housing redevelopment in Singapore 剖析城市阻力的多重性:新加坡达科他新月房屋重建项目

Civil society actors often combine or move between multiple modes of resistance beyond contentious protest politics and everyday resistance, yet this remains underexamined in the urban resistance literature. This paper aims to advance the knowledge on this alternative approach to resistance, particularly its potential to function as a democratic counterbalance to top-down urban planning, policymaking, and governance. Mobilising the lens of pragmatic resistance and institutionalist planning theory, the paper examines the acts of civil society resistance triggered by the state-led redevelopment of the Dakota Crescent public rental housing estate in Singapore. Empirical research data was collected through interviews, conversations, and e-mail exchanges with 22 civil society, governmental, political, grassroots, social service, and research actors, as well as a review of 177 documents. The findings uncover the ways in which civil society groups consciously reproduced dominant institutions of planning and activism as an effective strategy to increase the state's receptiveness to their advocacy objectives. Concurrently, they sought to reshape these institutions, often by adopting multiple resistance strategies within the same group or with other groups. This political balancing act between institutional reproduction and reshaping limited the possibility for democratic shifts at a structural level, but nevertheless offered a valuable means of influencing site-specific plans, policy problem definitions, and informal governance processes.
除了有争议的抗议政治和日常抵抗之外,公民社会行动者还经常将多种抵抗模式结合起来或在多种模式之间转换,但城市抵抗文献中对此的研究仍然不足。本文旨在增进人们对这种替代性抵抗方式的了解,尤其是其作为对自上而下的城市规划、决策和治理的民主制衡的潜力。本文以实用主义抵抗和制度主义规划理论为视角,研究了由国家主导的新加坡达科他新月公共租赁屋重建项目所引发的民间社会抵抗行动。本文通过与 22 位民间社会、政府、政治、基层、社会服务和研究人员的访谈、对话和电子邮件交流,以及对 177 份文件的审查,收集了实证研究数据。研究结果揭示了民间社会团体如何有意识地再现主流的规划和行动机构,以此作为一种有效策略来提高国家对其宣传目标的接受度。与此同时,他们还寻求重塑这些机构,通常是在同一团体内部或与其他团体一起采取多重抵制策略。这种制度复制与重塑之间的政治平衡行为,限制了在结构层面进行民主转变的可能性,但却为影响具体地点的规划、政策问题定义和非正式治理过程提供了宝贵的手段。

The findings uncover the ways in which civil society groups consciously reproduced dominant institutions of planning and activism as an effective strategy to increase the state's receptiveness to their advocacy objectives. Concurrently, they sought to reshape these institutions, often by adopting multiple resistance strategies within the same group or with other groups. This political balancing act between institutional reproduction and reshaping limited the possibility for democratic shifts at a structural level, but nevertheless offered a valuable means of influencing site-specific plans, policy problem definitions, and informal governance processes.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"155 ","pages":"Article 105509"},"PeriodicalIF":6.0,"publicationDate":"2024-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142537497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The burgeoning capabilities of artificial intelligence (AI) have prompted numerous local governments worldwide to consider its integration into their operations. Nevertheless, instances of notable AI failures have heightened ethical concerns, emphasising the imperative for local governments to approach the adoption of AI technologies in a responsible manner. While local government AI guidelines endeavour to incorporate characteristics of responsible innovation and technology (RIT), it remains essential to assess the extent to which these characteristics have been integrated into policy guidelines to facilitate more effective AI governance in the future. This study closely examines local government policy documents (n = 26) through the lens of RIT, employing directed content analysis with thematic data analysis software. The results reveal that: (a) Not all RIT characteristics have been given equal consideration in these policy documents; (b) Participatory and deliberate considerations were the most frequently mentioned responsible AI characteristics in policy documents; (c) Adaptable, explainable, sustainable, and accountable considerations were the least present responsible AI characteristics in policy documents; (d) Many of the considerations overlapped with each other as local governments were at the early stages of identifying them. Furthermore, the paper summarised strategies aimed at assisting local authorities in identifying their strengths and weaknesses in responsible AI characteristics, thereby facilitating their transformation into governing entities with responsible AI practices. The study informs local government policymakers, practitioners, and researchers on the critical aspects of responsible AI policymaking.
人工智能(AI)能力的蓬勃发展,促使全球众多地方政府考虑将其融入到政府运作中。然而,人工智能显著失败的事例加剧了人们对道德问题的关注,强调地方政府必须以负责任的态度对待人工智能技术的采用。虽然地方政府的人工智能指导方针努力纳入负责任的创新和技术(RIT)的特点,但仍有必要评估这些特点在多大程度上被纳入政策指导方针,以促进未来更有效的人工智能治理。本研究通过专题数据分析软件进行定向内容分析,从 RIT 的视角仔细研究了地方政府的政策文件(n = 26)。研究结果表明(a) 在这些政策文件中,并非所有的 RIT 特征都得到了同等的考虑;(b) 政策文件中最常提及的负责任的人工智能特征是参与性和深思熟虑;(c) 政策文件中最少出现的负责任的人工智能特征是可适应、可解释、可持续和可问责;(d) 由于地方政府处于识别这些特征的早期阶段,因此许多考虑因素相互重叠。此外,本文还总结了一些策略,旨在帮助地方政府确定其在负责任的人工智能特征方面的优势和劣势,从而促进其转变为负责任的人工智能实践的治理实体。本研究为地方政府决策者、从业人员和研究人员提供了有关负责任的人工智能决策关键方面的信息。

This study utilizes big data from telecommunication companies to analyze the transient population in 119 neighborhood parks in Seoul in order to determine the actual population of urban parks and investigate the factors influencing their utilization. Park utilization is defined as the number of people per unit area of a park. The factors affecting park utilization include individual park characteristics such as the degree of aging, park type, internal park facility characteristics, and park location characteristics. Park location characteristics were derived using network analysis to examine accessibility, land use, and population within each park's service area. Using a hierarchical regression model, we found that individual park characteristics, including age and park type, had the greatest impact on park use, followed by park location and internal facility characteristics. Specifically, as park age increased by one year, utilization decreased by 1.2 %. Utilization was 5.3 times higher in living zone neighborhood parks and 1.44 times higher in walking zone neighborhood parks compared to city/regional zone neighborhood parks. Parks with educational facilities and those situated near subway stations were more likely to be used. Additionally, the larger commercial areas and fewer residential areas near the park, the greater the utilization of neighborhood parks.
本研究利用电信公司的大数据对首尔 119 个街区公园的流动人口进行分析,以确定城市公园的实际人口,并研究影响其利用率的因素。公园利用率是指公园单位面积内的人数。影响公园利用率的因素包括公园的个体特征,如老化程度、公园类型、公园内部设施特征和公园位置特征。公园位置特征是通过网络分析得出的,以研究每个公园服务区内的交通便利性、土地利用和人口。通过分层回归模型,我们发现年龄和公园类型等单个公园特征对公园使用的影响最大,其次是公园位置和内部设施特征。具体来说,公园年龄增加一岁,利用率就会下降 1.2%。与城市/区域带街区公园相比,生活带街区公园的利用率高出 5.3 倍,步行带街区公园的利用率高出 1.44 倍。有教育设施的公园和靠近地铁站的公园使用率更高。此外,公园附近的商业区越大、住宅区越少,邻里公园的使用率就越高。

The article analyses, from the point of view of Spanish Airbnb hosts, the options for converting rented short-term units into alternative and social housing. Framed in the self-determination theory (SDT), different intrinsic and extrinsic motivational variables for home sharing are combined, through cluster analysis, to identify three different hosts' profiles (social and economic motivated, economic motivated and social motivated). To collect data a survey was conducted to a sample of the population who own a house listed on Airbnb (114 valid responses). The results show that each profile considers different motivations and life strategies when sharing their primary residence and this is related to the fact that they have different willingness to replace Airbnb with alternative and social uses. Specifically, hosts who have an intrinsic social motivation for home sharing are more willing to switch to social housing than those who have strictly extrinsic economic motivations. Finally, some recommendations are made for local administrations interested in generating housing policies that strategically incorporate short-term rented accommodation hosts.
文章从西班牙 Airbnb 房东的角度出发,分析了将短期出租单位转化为替代性社会住房的选择。文章以自我决定理论(SDT)为框架,通过聚类分析,将房屋共享的不同内在和外在动机变量结合起来,确定了三种不同的房东特征(社会和经济动机、经济动机和社会动机)。为了收集数据,我们对在 Airbnb 上拥有房屋的人群进行了抽样调查(114 份有效回复)。调查结果显示,每种类型的人在分享自己的主要住所时都会考虑不同的动机和生活策略,这与他们用其他用途和社会用途取代 Airbnb 的意愿不同有关。具体而言,与那些纯粹出于外在经济动机的房东相比,那些出于内在社会动机而分享住房的房东更愿意转而使用社会住房。最后,本文为有志于制定住房政策的地方政府提出了一些建议,以便战略性地将短期租赁住房的房东纳入其中。
