SPATIAL VARIATIONS IN GROCERY PRICES: FURTHER ATTEMPTS AT MODELING

Significant housing discrimination against Blacks continues to exist in Metropolitan Miami, as it does in most other large United States cities. Blacks in Miami live in neighborhoods that are not nearly as segregated by socioeconomic status as are Hispanic and non-Hispanic White neighborhoods. This study uses data derived from interviews of 432 Black heads of households living in Miami neighborhoods that are at least 50% Black. Although most of the African Americans interviewed said they think their neighborhood is desirable and said they want to live where they do, it is clear that they are not living where they most prefer. They live in predominantly Black neighborhoods because they feel unwelcome in White neighborhoods and they fear housing discrimination in the latter. Among other problems, the continued residential concentration of Blacks in predominantly Black neighborhoods of mixed socioeconomic status in Miami results in a bidding up of the price of housing that is left for the less affluent Blacks.     

邻避设施空间分布特征及其与周边住宅价格的关系——广州案例

随着中国城镇的快速发展以及市民环境意识的提高,由邻避设施引发的矛盾日益增多。合理规划邻避设施,是促进环境正义、推动社会和谐的重要课题。论文从“规划云平台”获取广州主城区邻避设施的地理信息数据,通过Python语句编码收集广州主城区小区平均房价数据,运用克里金插值法分析邻避设施的空间分布特征,构建多元线性回归模型和地理加权回归模型研究邻避设施与周边住宅价格的关系。研究发现,广州主城区邻避设施的布局与低收入住宅区的分布在空间上具有一致性,邻避设施主要分布在房价较低的住宅区周边;邻避设施对周边小区房价的影响与邻避设施的类型和所在区位相关,城市边缘区的邻避设施对房价造成了显著的负面影响,而城市中心良好的区位条件、基础设施与公共服务配套一定程度上抵消了邻避设施的负外部性;污名化类的邻避设施对房价的影响程度明显小于污染类、风险聚集类和心理不悦类邻避设施。本研究对有关城市邻避设施的科学规划布点具有一定的借鉴和指导意义。     

The concentration of urban crime in space by race: evidence from South Africa

Crime inequality in neighborhoods by race is blamed on social inequalities borne out of segregation and economic discrimination. South Africa is a country synonymous with racial-spatial segregation and discrimination as a result of legislatively enforced policies of the former apartheid government. This study examines whether urban crime inequalities by race exist in the city of Tshwane, South Africa and identifies the empirical causes of these crime inequalities. Violent and sexual crime was found to concentrate in Black African neighborhoods, while property crime was concentrated in neighborhoods classified as “Mixed”. The causes of crime in neighborhoods were found to vary across racial groups with results suggesting non-uniformity in the extent to which the various constructs impact crime based on race. The results challenge the notion that segregation and economic discrimination uniformly impacts affected communities. Explanations for the findings are provided in the context of an increasingly eclectic post-apartheid South African city.     

THE EMERGENCE OF AFFLUENCE IN BEIJING: RESIDENTIAL SOCIAL STRATIFICATION IN CHINA'S CAPITAL CITY

Since 1987, the Chinese government has begun to liberalize its approach to land markets, allowing for the development of commercial residential housing and sparking greater distinctions in housing quality. At the same time, there have been growing income differentials among Beijing's residents. This paper discusses how Beijing's new urban affluent have begun to take advantage of greater housing choices. It reports on a survey conducted in 1997 that uncovers the occupational characteristics, consumption patterns, housing characteristics, and residential locations of affluent residents. The results indicate that Beijing's new urban affluent are beginning to share some of the consumption features of middle-class Westerners. At the same time, social segregation is still nascent in Beijing. There is now only a sprinkling of affluent neighborhoods in the city, and a slight majority of wealthier respondents continue to live in public housing. Moreover, few are able to afford detached single-family housing or a private automobile. The continuation of current trends could both deepen and broaden social segregation in Beijing, as class divisions come to be manifested in separate neighborhoods.

基于计划行为理论的城市居住分异对居民健康活动的影响研究

虽然国内外大量研究探讨了居住环境与健康关系,但较少将城市地理学与社会心理学结合,从理性行为角度分析居住环境对居民身体活动的影响机制。论文引入计划行为理论的分析框架,以中国居住空间分异的特殊性为切入点,以南京为实证对象,运用结构方程模型解析居民态度、主观规范、知觉行为控制和行为意向对居民身体活动的影响路径。结果表明：传统社区、单位社区、保障房社区、城中村和商品房小区的居民社会经济特征和健康活动存在明显差异。影响居民健身意向和健身活动的最重要因素为知觉健身行为控制强度感知。消减居民健身的主观限制,包括为其提供健身设备、公共健身资源和对健身进行补贴,可提升其健身活动水平。研究结果可为通过改善建成环境进行健康行为的主动干预提供对策建议。     

The Persistence of Segregation in Buffalo,New York: Comer VS. Cisneros and Geographies of Relocation Decisions Among Low-Income Black Households

Debates about the causes of segregation continue to consider the role that own-race preferences have in understanding the persistence of racial residential segregation in American cities. In this paper, I offer an alternative to the own-race preference model. I argue that segregation of low-income Black households from Whites persists in Buffalo, New York, because the spatial rootedness of Blacks' survival strategies leads households to choose housing in the central city, where their social networks and most Black households live. I illustrate this argument by exploring the multiple reasons for why a group of African American households, who were prompted to move through the settlement of a high-profile housing discrimination lawsuit, chose to relocate to neighborhoods in the central city in Buffalo. I adopt a context-sensitive perspective in making the argument and further argue that such approaches are ultimately useful in capturing the complex reasons that underlie the persistence of segregation.     

广州保障性住区的社会空间特征

城镇保障性住房制度直接塑造了保障性住区,这一“国家化”的社会空间在不同的城市呈现出迥异的类型。通过梳理城镇保障房制度的演变及在广州的实施,将广州的保障性住区分为四类:1986～1998年建成的承接单位体制内住房困难户的住区、1999～2005年建成的承载党政机关和教医系统住房困难家庭的住区、2006年后新建的主要承载具有城市户籍的社会双困群体的住区、建设历程跨越多制度阶段的承载多类保障群体的综合住区;通过“典型案例”研究,各类保障住区的现状社会空间可归纳为:“类西方‘社会型’公共住区的极度贫困均质空间”、“介于中国城市普遍存在的贫困集聚区的‘贫困混杂空间’和西方混合社区的‘有序混合空间’之间但混杂性高的贫困空间”、“介于两者之间但有序性强的混合空间”、“类商品房住区”的均质非贫困空间。     

Where rights begin and end in Puerto Rico's gated communities

In 1992, Puerto Rico's governor and police superintendent incorporated the National Guard with local police in a militarized battle against crime. Mano dura contra el crimen (strong arm/iron fist against crime) policies led to the gating of 82 public housing communities in the island. Simultaneously, privileged private communities organized and petitioned municipalities to retrofit their neighbourhoods with gates in the name of safety. These enclosures followed the privatized management of all public housing communities in the island only a few years before. Based on ethnographic research, I examine the sociospatial outcomes of these policies, how they reframe community participation and deploy a discourse of self‐responsibility that distributes power unequally across private and public housing communities. While in the privileged communities these policies have cultivated community leaders and invigorated social life as residents take control over public space, the gates in the communities of the poor reflect a skeletal structure of democracy. Private management companies impose increasingly restrictive regulations in attempts to organize the community and the only recourse to participation is to engage in small acts of everyday resistance, from apathy to subversion. As part of larger neoliberal tendencies to retrench the ‘public’ in favour of the ‘private’, the mano dura policies curtail democracy as the voices of the poor are silenced and the scope of efficacy of the rich expands.     

重庆市公共租赁住房社区居民的职住空间匹配

居住与就业间的空间组织是城市空间结构的重要组成要素之一,国外自20 世纪60 年代提出后引发了大量关于弱势群体居住和就业空间机会及其关系的实证研究。近年来在中国城市快速空间重构的背景下,中低收入群体的职住分离现象也引起广泛关注。运用职住空间错位理论,以重庆市主城区公共租赁住房社区为案例进行研究,对541 份有效问卷的统计分析表明:① 公共租赁住房居民搬迁前通勤距离与通勤时间的均值分别从6.5 km与32 min,增加到搬迁后的15 km与52 min;② Logit回归分析表明,群体类型对公共租赁住房居民通勤时间差异影响最为显著,年龄与居民通勤时间呈负相关关系,性别与年龄对通勤时间产生较显著影响。③ 公共租赁住房供应的政策性因素造成了被动迁移型空间不匹配现象,是其住户的区位选择与主要就业场所不匹配而引发的,因此需要深入研究公共租赁住房合理的空间布局方案和实施途径,尽可能将公共租赁住房区位规划在内城。     

Mutual relationships in neighborhood socioeconomic change

In this article, we investigate the factors that lead to changes in the socioeconomic complexion of urban neighborhoods along four critical dimensions: crime, youth social distress, home ownership, and economic conditions. We argue that the dynamics of these dimensions are better apprehended simultaneously considering their potential mutual relationships and we propose a cross-lagged panel model approach within a structural equation modeling framework. Neighborhoods in Charlotte, North Carolina, are used as a case study, and change is modeled at several time lags throughout the 2000–2010 decade. Findings indicate that the model performs well and that it offers a very promising avenue for modeling the socioeconomic changes of neighborhoods that accounts for complex longitudinal effects as well as spatial dependencies. Specifically, it shows that lower human capital manifested by a decline in youth indicators is significant in explaining subsequent increases in crime and declines in economic indicators. Also, the predominance of housing stock constructed in the 1950s and 1960s is a significant trigger of declines across all neighborhood indicators. Finally, spatial spillover effects between neighborhoods are found to be short-lived and dissipate after a few years.     

Gentrification and the suburbanization of poverty: changing urban geographies through boom and bust periods

Many postindustrial cities across Europe and other contexts are marked by growing social–spatial inequalities, housing liberalization, and gentrification, which limit the housing options of low-income households. We investigated changes in the residential moves of different low-income households (working poor, low-to-middle income, and unemployed) in the Amsterdam and Rotterdam urban regions for the time period 2004–2013. We found an overarching trend for the suburbanization of poverty toward the urban peripheries and surrounding regions. While this trend appears to be relatively crisis resistant in the tight Amsterdam housing context, it is more cyclical in Rotterdam and has slowed following the global financial crisis. Low-to-middle income and unemployed households are increasingly moving to the urban regions surrounding cities, particularly to higher density satellite towns. Nevertheless, a growing number of working poor households remain highly urbanized, employing various coping strategies to acquire housing. This paper reveals how the suburbanization of poverty is both a direct process of poor households moving from city to suburb, and a broader indirect process caused by exclusionary mechanisms such as the decreasing accessibility and affordability of inner-urban neighborhoods, which reflect broader changes in the geography and socioeconomic patterning of urban regions.     

Immigration and community development in New York City

Community development corporations play a central role in the provision of affordable housing and social services in the contemporary American welfare state. This organizational form, however, emerged in the distinctive, historical political-economic context of the Black Power Movement and America's Great Society. American cities are now very different places, transformed by immigration from spaces of Black–White separation to much more heterogeneous and diverse spaces. In this article, our central question is whether, and how, these vital service organizations are incorporating immigrants into their work. We find that the answer varies, and such variations indicate differential access, or “differential citizenship”—in the urban structure of the contemporary American welfare state.     

University Campuses and Housing Markets: Evidence from Nanjing

China has witnessed unprecedented growth of its universities in recent years. Because they function as a sort of urban quasi-public good, university campuses generate a variety of externalities within surrounding communities, including their impacts on adjacent housing markets. Through an analysis of the case of Nanjing, China, this study attempts to quantify the association between university campuses and housing markets in China and to help policymakers, planners, and community members better understand campus–community relationships more generally. The study yields the following findings. First, university campuses have been capitalized into the housing prices of their neighboring communities in Nanjing. Second, in the proximate communities, university campus spillover benefits involve trade-offs with the amenity values of other public goods. Third, campus capitalization effects vary across different tiers of universities. Based on the empirical results, we offer several policy implications, key among which are that policymakers need to acknowledge and rationally distribute the potential spillover benefits of the campus to multiple stakeholders; campus and residential communities should be planned synergistically to optimize land use efficiency; and universities should be fully engaged with their surrounding communities to maximize mutual benefits.     

The Pen or the Sword: A Situated Spatial Analysis of Graffiti and Violent Injury in Vancouver,British Columbia

Graffiti is a ubiquitous feature of the urban landscape commonly perceived to be a symptom of disorder, deprivation, and violence. Broken windows theory asserts that it is also a cause. To examine this, we conduct a geographic correlation study of graffiti and violence using geographic information systems. A strong spatial covariation is observed, with spatially dependent residual clusters suggesting that the graffiti–violence relationship is context dependent and varied. Ferrell and Weide's spot theory provides a lens for situating hot spots and facilitating a more nuanced interrogation of graffiti and violence in several Vancouver neighborhoods. We advocate for situated spatial analyses of interpersonal violence to inform public health interventions and advance policymaking beyond the popular aesthetic symbolism of urban space.

The divergent city: unequal and uneven development in St. Louis

In St. Louis, as in many other cities, decline and displacement occurred when key policies, prejudices, and plans interacted with broad economic restructuring to devastate poor and minority communities, while leaving White and middle-class communities largely intact. Amidst overall population loss and neighborhood decline are pockets of prosperity and gentrification within the central city. In this article, we analyze three significant planning interventions in St. Louis, Missouri, that spurred displacement of populations—urban renewal, triage, and the foreclosure crisis. We argue that the differential experiences of Black and White during each of these periods represent two faces of development: one in the north of the city that is largely Black, experiencing vacant land, high crime, and crumbling infrastructure; another in the south of the city that is largely White, enjoying pockets of vibrant commercial development, larger homes, and stable real estate markets. We analyze each period through a framework of uneven and unequal development and displacement, which we call the Divergent City Theory. Based on this theory, planners face an ethical obligation to plan for the future of their cities in a way that seeks to reconcile the structured race and class inequalities of the divergent city.     

UNAUTHORIZED SUBURBAN HOUSING PRODUCTION IN GREECE

Unauthorized and illegal housing construction in Greece has existed for decades, resulting from extensive rural-urban migration, the high cost of legal houses, housing's popularity as a means for capital accumulation, and ineffective land-use planning and regulation. This unauthorized housing development has moved from the cities of Greece to its suburbs, as the amount of urban land available for squatting has diminished. Greek citizens have found ingenious ways to construct illegal housing quickly and cheaply. Some of this housing is quite substantial, taking on the appearance of middle-income and even upper-income housing. Despite the undesirable consequences of unauthorized construction, laws and regulations have been largely ineffective in preventing it. Possible solutions continue to be explored, and additional remedies are suggested in this article. Yet unauthorized construction in Greece may disappear only when the income of the middle and lower classes reaches a level to enable them to acquire a house legally.     

Rethinking the Growth Machine: How to Erase a Chinatown from the Urban Core

Abstract

This article explores Houston's two Chinatowns within the context of the city's recent urban reinvestment and revitalization initiatives. It provides a history of the Chinatowns and examines their changing condition during the years that Houston was promoting ethnic diversity and urban revival. The analysis is framed within the growth machine perspective, as initially explored in Houston by Joe Feagin, and later by Jan Lin and Igor Vojnovic. Houston's late-20th-century urban redevelopment initiatives occurred during a period in history when Houston's Chinese entrepreneurs lost their influence over the local growth machine. The eventual outcome was the erasure of Houston's downtown Chinatown and the displacement of its residents from their lucrative urban core location. The disappearance of Old Chinatown and other urban ethnic neighborhoods—including Little Saigon and Freedmen's Town—from the urban core all took place as the Houston media and public were celebrating diversity, pluralism, and ethnicity in the city.     

SPATIAL PATTERNS OF BUSINESS LAND VALUES IN CHICAGO

While the United Kingdom's emerging brand of Third Way Urban Policy (TWUP) often associates itself with a kind of anarchic vision of self-regulating and self-reproducing local communities, it can in fact be thought of as a thinly veiled moral crusade against vulnerable residents living in deprived neighborhoods. Indeed TWUP might be best conceived as a "flanking support" for the neoliberal turn in urban governance in British cities; morally commendable communities are defined as those who can reattach themselves to the "mainstream" and stand on their own two feet within the terms set by neoliberal market economics. When these morally charged interventions fail to connect locally, they have the potential to stir conflict over who has the authority to judge forms of community life. Mapping and accounting for the uneven development of moral conflicts over community is therefore a pressing concern. To this end, this paper presents a comparative analysis of the different ways in which moral disputes over community have surfaced in two neighborhoods, in particular—the Gorbals in central Glasgow and Ballymun in north Dublin, neighborhoods that have become iconic of the British approach to urban renewal.     

Who has long commutes to low-wage jobs? Gender,race, and access to work in the New York region

Geographies of home and work have changed as public investment has favored central and distant suburban locations and as income inequality has increased. These changes result in shifting geographies of advantage that (dis)benefit gender and racial/ethnic groups unevenly. We examine commuting differentials by gender and race/ethnicity based on combinations of wages and commute times using data for the New York region.We find that Black, Asian, and Hispanic women and men are concentrated in jobs that have long commutes and low-wages, and Black and Hispanic workers’ concentrations increased from 2000–2010.Although Asian men and women remain overrepresented in that category, their share decreased in the 2000's.The urban core has become a region of heightened advantage, as White men, and an increasing share of White women, commute short times to well-paid jobs. Disadvantage has expanded for Black and Latina women whose long commutes are not compensated by well-paid employment.
