Cooling centres provide respite, safety, and social support during extreme heat events for populations that do not have the resources to own or operate in-home air conditioning. The objective of this study was to measure the spatial accessibility of cooling centres and analyze the associations between cooling centre access and marginalization in Montreal, Toronto, and Vancouver, Canada. The potential spatial accessibility of cooling centres within a 15-minute walk was measured at the dissemination area scale using the two-step floating catchment area method. A two-stage modelling approach was used to analyze the associations between cooling centre access and marginalization. Approximately 62%, 58%, and 54% of the populations in Montreal, Toronto, and Vancouver had access to at least one cooling centre. In Montreal and Vancouver, high marginalization areas were more likely to have cooling centre access than low marginalization areas. Of the areas with cooling centre access, smaller access scores were observed in areas with high residential instability. Approximately one-fifth of the areas in each city had no cooling centre access and high marginalization, and may be considered for future cooling centres or programs that improve accessibility to existing centres. 相似文献

在信息技术深度融合的网络社会进阶中,移动互联网支撑城市环境的即时共享与未来愿景,非在地的空间感知生成元宇宙类现实/虚拟的城市意象,网络媒介叠加于建成环境主/客观作用的传统经验感知,形成感知拼贴、地方再构、时间重叙、认知分异的意象特征。研究通过梳理互联网语境下的城市意象研究,揭示网络社会背景下城市意象的先验式建构过程,发现了意象节点偏离于城市社会经济活动峰值区域的一般规律,并归纳了互联网环境下城市意象研究的图片、文本和轨迹等应用素材,以丰富人本主义城市设计理论。 相似文献

近年来,随着我国港口资源整合、港区功能调整和港口城市的转型升级,沿海港口与所在城市的关系发展面临新的变化和挑战。本文以我国沿海港口为例,结合定量分析与定性讨论,聚焦我国沿海港口港城关系问题,剖析港城关系的演变及驱动机制。研究发现:我国大部分沿海港口已进入极度协调发展阶段,但发展趋势逐渐放缓,区域分化特征显著,港城协同度差距呈现再扩大的发展趋势。在研究期间,我国城市驱动型港口城市数量显著增加,港口驱动型和港城互驱型港口城市数量减少。建议通过政府政策引导、港产城融合发展和港口转型升级等方式,不断提升我国沿海地区港城关系整体协调发展水平,为新时期我国沿海港口与所在城市的高质量发展提供重要支撑。 相似文献

Information and communication technologies (ICTs) are often cited as an important factor in firm location decisions. This is especially true for firms engaged in information intensive activities and those that have a strong need for advanced services such as broadband. Despite the suggested importance of these technologies, quantitative work evaluating the link between firm location and broadband provision is sparse and existing knowledge remains largely theoretical and speculative. However, theoretical evaluations of the impact of ICTs on firm location do provide a foundation for quantitative analyses of this relationship and may be grouped into three schools of thought: the deconcentration school, the concentration school, and the heterogeneous effects school. The predictions made by these three schools of thought will be analysed in an exploratory context to better understand the relationship between firm location and ICTs, with a focus on broadband service provision. A combination of basic spatial statistical analytical tools and geographic information systems (GIS) will be used in an exploratory spatial data analysis framework to evaluate the relationship between firm location and broadband provision trends from 1999 to 2004 in the state of Ohio. Results suggest that changes in broadband provision have no relationship with changes in firm location. However, a disaggregated, firm level analysis of this relationship does provide statistically significant results for a subset of industrial sectors. Firm size is also found to impact the correlation between firm presence and broadband provision. These results suggest that firm size and industry are perhaps critical components in determining the relative importance of ICTs, such as broadband, in firm location decisions. 相似文献

The dynamic finite element equations of a two-dimensional structure made of axial-flexural frame elements with tendon-driven actuators have been derived. A critical review of classical optimal control theory is made with respect to its application to the control of structure under seismic excitations. Seven control algorithms, including two newly proposed algorithms, have been described, investigated and discussed. The need of an optimal observer, Kalman filter, is discussed. The validity of separation theorem applicable to the optimal stochastic control of structure for earthquake resistance is shown. How the control system perform under the circumstances of actuator saturation is also shown. Several numerical examples are worked out to demonstrate and compare the efficiency and limitations of those control algorithms. 相似文献

The article examines the first official, national Holocaust memorial day in Italy, the so-called Giorno della memoria (Day of memory), marked on the 56th anniversary of the liberation of Auschwitz on 27 January 2001. It looks at the ways in which the day acted as a filter for issues of national collective memory and identity, in particular state and public negotiation of the legacy of Fascism, as well as addressing broader issues of Holocaust remembrance. The article looks first at the origins of the Giorno della memoria in political and in legislative terms. Then it sketches in the events of the day itself, at national and local levels, in political, educational and cultural terms. This is followed by an analysis of media coverage and contemporary commentary, showing how various lines of interpretation addressed general issues related to the Holocaust and specifically Italian historical, ideological and contemporary questions. 相似文献

New firm formation is commonly seen as a representation of the entrepreneurial capacity of a region. However, there is also a group of new firms that is based on the replication of existing business practices rather than on the entrepreneurial introduction of new practices. Both groups of founding types have a role in the explanation of regional economic development. This paper displays the spatial and industry patterns of two types of new firm formation representing each function: individual foundings and organisational foundings. 相似文献

This paper reflects upon treatments of the body in both disability studies and disability geography, taking seriously the impaired body in its immediate materiality: in its flesh‐and‐boneness, in how it deals with everyday practices in everyday places, as this embodiment is ‘voiced’ by disabled people themselves. The paper discusses Hansen's in‐depth research with a sample of disabled women living in Scotland and Canada, teasing out their experiences of coping with impaired bodies in non‐disabled spaces. Particular attention is given to their own bodily practices, complete with ‘timings and spacings’ that may depart from what is supposedly normal for non‐disabled people. It is also shown how these women resist ableist accommodations that entail both modifying external spaces and ‘correcting’ bodily differences. The paper concludes by identifying a key but neglected step within the ‘politics’ of better accommodating disabled people: namely, shifting the emphasis from (aiding disabled people in) doing things ‘normally’ to (underlining for all of ‘us’) simply the normality of doing things differently. 相似文献

Socio‐spatial differentiation or the spatial arrangement of social groups in cities has long been the subject of scholarly attention in urban studies from a variety of perspectives. In many contemporary societies, the development industry plays an important and growing role in socio‐spatial differentiation. This paper presents a conceptual model for the empirical analysis of the role of this industry in shaping urban social space. 相似文献
