HOUSING CONSTRUCTION, VACANCY CHAINS, AND RESIDENTIAL MOBILITY IN WINDSOR

R esidential m obility is one of the most important forces underlying changes in the social composition and physical characteristics of urban areas (Rossi 1955, p. 2). Consequently, numerous studies on residential migration have been carried out in order to comprehend this process better and thereby aid in the assessment of migration theories and in the development of appropriate models. Mobility studies have examined the characteristics of outmigration areas and households, motivations to move, satisfaction achieved through relocation, and the impact of residential changes. However, as Maher (1974) points out, previous analyses are incomplete in that they tend to focus on the demand characteristics of residential relocation and to omit the supply side of the process, the available housing stock. This study attempts to rectify this omission by considering the provision of newly constructed single-family detached housing in Windsor and the resultant migration patterns and processes through vacancy chain analysis. The demand and supply concepts of residential mobility are examined with regard to the housing multiplier generated by different locations and values of new homes, the socio-economic and demographic characteristics of households at various positions in the turnover process, the reasons for moving, and the spatial patterns of residential moves originating from new housing. In addition, by focusing on a specific form of housing the study avoids problems which may arise from aggregate level analyses of households adjusting to new housing opportunities.

Urban Regeneration for Sustainable Development: The Role of Sustainable Housing?

This article examines the extent to which a number of urban regeneration approaches involve sustainable housing. Specifically, it assesses the potential of eco-neighbourhoods, urban villages and new urbanism to contribute to sustainable regeneration. The article highlights the advantages and disadvantages of each approach from a sustainable housing perspective and, in particular, evaluates the extent to which the environmental and social aspects are addressed in each. It concludes that both aspects are frequently neglected in regeneration programmes and that this is likely to result in unsustainable urban renewal in many cities.

Why the Homeless Rebel: Housing Struggles in post-Apartheid South Africa

Abstract

Post-apartheid housing struggles urgently need to be addressed in order to consolidate the inclusivist democracy in South Africa. Former white minority governments restricted housing in order to control the movement of Africans and their labour. This paper analyses aspects of post-apartheid housing protest. The argument is that such protests are rooted in a problematic rights discourse of the anti-apartheid struggle, and in the new constitution's recognition of the right of access to adequate housing, which is nonetheless, subjected to fiscal constraints. The article's second focus is on a legacy of land dispossession, which also hinders housing delivery. Failure to realise the right to housing fuels some of the most important conflict that will shape future organisation of state institutions and relations between the state and society.     

The environmental aspects of reterritorialization: Environmental facets of Israeli–Arab agreements

Reterritorialization processes change the demarcation and function of boundaries and create new realms of authority. As political and natural boundaries rarely coincide, such processes increase the discrepancies between spheres of control and natural systems, thereby increasing the externalization of environmental problems and raising the transaction costs of addressing them. The actual environmental implications of reterritorialization processes are a function of both the direct barrier effects of boundaries and the role of boundaries as separators between management regimes. In contrast to environmental agreements, which focus on a very limited set of issues, agreements that are negotiated as part of reterritorialization processes may address a wide array of environmental issues. This paper asks which environmental issues are addressed in such agreements, and what are the factors that affect the range of issues that are addressed, and the extent to which they are addressed. To this end, the three agreements signed between Israel and her neighbors, Egypt, Jordan and the Palestinians, are analyzed. This analysis shows that the issues that tend to be addressed are either high profile issues (such as water in the Middle East) or those that do not impinge on ‘high politics’. This finding suggests that there is a latent contradiction between political and environmental considerations in negotiating such agreements. While management regime effects are, arguably, more important than direct barrier effects from an environmental perspective, they are largely viewed as internal issues, and hence they are not likely to be addressed in such agreements.

复杂理论视角下城市健康地理学探析

城市公共健康问题是根植于所依托的地域空间背景下的复杂问题,因而,目前学界主要以还原论的模型假设来分析影响城市健康的复杂多因子关系时存在一定局限。本文在分析城市健康地理问题的"地方"复杂性基础上,提出用复杂理论认识城市的健康问题,将城市健康地理系统看作为具有开放性、组分的知识局限性、自组织性、路径依赖、涌现性、正反馈和锁定特征的复杂系统。从复杂理论视角探讨了当前城市健康地理学研究的三个主要议题,进而提出复杂理论视角下城市健康地理学研究框架及未来研究展望。     

Planning for Rural Housing in the Republic of Ireland: From National Spatial Strategies to Development Plans

This paper examines the role of spatial planning as a policy framework for managing rural housing within an integrated territorial development strategy. The paper focuses on the Republic of Ireland, which provides a useful case for analysing spatial planning and rural housing relationships, due to the State's recent shift towards spatial planning (formalized with the publication of the Irish National Spatial Strategy), as well as the level of housing construction that has been observed in an increasingly post-productivist countryside (triggered by counter-urbanization flows, increased affluence and demands for second holiday homes, etc.). The paper reviews all policy instruments that have been used to manage rural housing at various scales (from national strategies to local level development plans). It is argued that while spatial planning adopts an integrative vocabulary, as policy moves down the spatial scale hierarchy, multi-dimensional spatial goals are implemented through traditional, narrow land-use regulation. This often leads to rural housing being addressed in isolation from its wider social and economic context, disconnecting housing from wider rural community issues and ultimately failing to deliver a coordinated and coherent spatial policy for managing rural settlements.     

空间视角下农村社会关系变迁研究——以山东省枣庄市L村“村改居”为例

以空间为视角,以"村改居"为案例,说明了农村居住空间改观对农村社会关系嬗变的影响。首先,农民集中居住后,公寓楼的阶梯设置造成了垂直方向上行走的高差区分。由于楼梯对身体的规训以及安全性差,导致高差间交往的不便;其次,公寓楼单元化的"门-房"一体结构导致公共空间与私人空间的界限明朗化,缺少了半私密性空间的过渡,空间闭合与开放的矛盾变得不可调和,农村居民户内交往意愿降低;再次,公共空间相对于私人生活区的外设与远离,导致公共空间使用率下降。农村居民间规模化和混合型交往缺失,公共空间没有承担起公共交往的功能。农村社会关系因此从"分散的不规则集中"变为"集中的均匀分散"。     

A geography of repoliticisation: Popularising alternative housing models in Oslo

The question of the political has gained renewed relevance in recent years. New movements are challenging what has been called ‘the post-political consensus’ and have facilitated the repoliticisation of a wide range of social, political and cultural phenomena—both on the left and the right. One task for geographers is to understand this repoliticisation spatially. The housing sector is a prime example of how such a repoliticisation occurs. With an emerging global urban housing affordability crisis, housing is becoming an important arena for engaging in emancipatory democratic politics. In this paper, we use Oslo as a case to analyse how housing, which has long been governed through liberal consensus, is being repoliticised. We investigate Oslo's agenda of establishing a ‘third housing sector’ beyond the privatised model, and its role in popularising alternative models in housing. We focus on the mobilisation and rearticulation of the genealogy of failure of housing in Oslo and the alternative housing solutions brought together in the city. Discussing the emerging geographical referencescape of housing as a distinctly spatial process of politicisation we show how arguments and positions gain legitimacy by situating references to other situations and places in a multiplicity of local and foreign arenas.     

细胞自动机及在南京城市演化预测中的应用

细胞自动机(Cellular Automata)是一种具有时空计算特征的动力学模型,其最主要的特点是复杂的系统可以由一些很简单的局部规则来产生,特别适合城市等空间复杂系统的时空动态模拟研究。本文利用地理信息系统(GIS)和细胞自动机的有机集成而构筑的CA-Urban模型模拟南京市的土地利用的动态演化过程。对南京三个开发区的发展以及南京能否跨江发展等存在争议的问题作了预测和评估。通过设置不同的转换规则、参数,从一个侧面为我们展示了城市系统的宏观演化的可能模式,为城市规划等提供了辅助决策。最后提出了模型的缺点及其展望。     

A MODEL OF URBAN HOUSEHOLD BEHAVIOR WITH LEISURE CHOICE

This paper provides a complete comparative-static analysis of the simplest model of urban household behavior that incorporates time explicitly. Results involving the housing-price function and the effects on housing consumption and location (radial distance from the CBD) of exogenous changes in preferences for housing, housing price, and money costs of transportation are the same as in models not incorporating time explicitly. In addition, it is found that housing consumption and location are negatively related to commuting time, positively related to nonwage income, and ambiguously related (both a priori and empirically, for reasonable values of the relevant variables) to the wage rate.     

海口城市建成环境对高峰期网约车通勤出行的影响——基于滴滴出行数据

网约车的普及重塑了居民的通勤行为。城市建成环境作为居民通勤出行的制约因素,是交通地理学的重要研究议题。采用海口市滴滴出行订单数据,刻画格网尺度的居民通勤时间与通勤距离的空间分异格局,并运用地理探测器分析城市建成环境对居民通勤出行的影响。结果表明：(1)早晚高峰通勤时间在空间上表现为中间集聚、四周分散的分布特征;早晚高峰通勤距离呈现梯度递增的圈层结构。(2)不同维度的建成环境因素对通勤时间和通勤距离的影响程度不一;其中距公交站距离、距市中心距离、职住比、道路邻近度是核心影响因素;人口密度、就业可达性、路网密度产生较为显著的影响。(3)从影响效应看,交通区位优越、职住趋于平衡、道路邻近度高、就业可达性好能引导网约车与多元交通协同发展。结果可为改善交通出行环境、优化居民通勤结构提供借鉴。     

Preferences for Housing, Jobs, and Commuting: A Mixed Logit Analysis

This paper reports stated preferences of Dutch workers for combinations of housing, employment, and commuting. The analysis uses standard logit models as well as mixed logit models. Estimation results offer insights into the relative importance of various aspects of housing, employment, and commuting. Households dislike commuting and the value of commuting time implied by the model is high in comparison to the wage rate. Nevertheless, preferences for some housing attributes are strong enough to make substantially longer commuting acceptable to most workers. Of special interest is the strong preference for living in small-or medium-size cities, especially among two income households. Using a mixed logit model instead of a standard logit model results in a substantial improvement of the loglikelihood, reflecting the importance of heterogeneity among respondents. If no individual characteristics are incorporated into the model, the mixed logit implies substantially lower average monetary evaluations of most attributes. These differences are much smaller if some individual characteristics are incorporated into the model.     

试论历史人类学与中国近代史研究中的几个问题

兴起于20世纪80年代中后期的历史人类学,尽管从学术传承上分属于两个不同的学科,但它的出现为消融历史学与人类学的边界,促成两个学科的交叉与融合,起到了不可低估的作用。在历史学内,“历史人类学”的形成亦经历了一个从社会史、社会文化史到历史人类学的演变过程。而在中国近代史领域,历史人类学已经展开一些研究实践,但是尚需进一步提倡。这种提倡表现在三个方面:底层视角、区域经验、文本与田野互动。历史人类学会对中国近代史研究产生有益的影响,会成为一种介于宏大叙事与经验性实证研究的“中层理论”。从历史学科的本位出发,历史人类学对人类学的吸收借鉴颇多,但是不能轻易放弃历史学科本位。     

The Space of Local Control in the Devolution of us Public Housing Policy

Sweeping changes in national policy aim to radically transform public housing in the United States. The goal is to reduce social isolation and increase opportunities for low income tenants by demolishing ‘worst case’ housing, most of which is modern, high‐rise buildings with high vacancy and crime rates, and replacing it with ‘mixed‐income’ developments and tenant based assistance to disperse current public housing families. Transformation relies on the national government devolving more decision‐making power to local government and public housing authorities. The assumption here is that decentralizing the responsibility for public housing will yield more effective results and be more efficient. This paper explores the problematic nature of decentralization as it has been conceptualized in policy discourse, focusing on the underlying assumptions about the benefits of increasing local control in the implementation of national policy. As this paper describes, this conceived space of local control does not take into account the spatial features that have historically shaped where and how low income families live in the US, including racism and classism and a general aversion by the market to produce affordable rental units and mixed‐income developments. As a result, this conceived space of local control places the burden on low income residents to make transformation a success. To make this case, Wittgenstein's (1958) post‐structural view of language is combined with Lefebvre's view of space to provide a framework in which to examine US housing policy discourse as a ‘space producing’ activity. The Chicago Housing Authority's Plan for Transformation is used to illustrate how local efforts to transform public housing reproduce a functional space for local control that is incapable of generating many of the proposed benefits of decentralization for public housing tenants.     

Welcome to the club! An exploratory study of service accessibility in commodity housing estates in Guangzhou,China

In post-reform China, gated commodity housing estates play a crucial role in the provision of urban services. Such collective service provision is criticized in the urban studies literature, because ‘club goods’ are thought to exclude people that do not live in gated communities. This paper reflects on the global relevance of that argument with an exploratory study in Guangzhou, China. We argue that access to collective services is structured in local social practices, involving diverse actors and specific rules and resources. Discussions on the exclusionary effects of service provision through gated communities should therefore focus on the characteristics of these practices of access in specific cities. Employing this perspective, the paper shows that in Guangzhou at least two mechanisms partly ease the exclusion of non-residents from club goods. On the one hand, municipal government maintains a considerable role in service management, mediating exclusion from services for people who do not live in commodity housing estates. On the other hand, generally the management of services is separated from housing estate management, and service providers try to increase profits through service provision to non-residents. We discuss the consequences of such mediations for an adjusted research agenda on service provision by gated communities.     

Reflecting on a Decade of Australian Social Housing Policy: Changes in Supply and Geography, 2001–2011

This paper compares the intent of three Australian social housing policy interventions in the decade to 2011 with outcomes shown in time series data from the Australian Bureau of Statistics Census. The three policy interventions are the supply stimulus that occurred in 2009 with funding to construct almost 20 000 new social housing dwellings by 2012, the push to diversify social housing supply through the transfer of public housing stock to community not‐for‐profit housing providers, and the physical renewal of public housing estates to reduce concentrations of social deprivation. Its aims are threefold: to understand how the supply and geography of social housing dwellings has changed over the past decade; to relate these changes to the objectives of social housing policy in the time period; and to identify issues for the future of social housing in Australia emerging from identified disparities between policy rhetoric and supply reality. The paper employs quantitative analysis of social housing supply for all of Australia and mapping of social housing supply changes in the east‐coast mainland state capital cities. This analysis reveals the overall stagnation of social housing supply in Australia over the previous decade, combined with evidence of stock loss in areas of renewal in some cities.
