Making our neighborhoods,making our selves     

Ron Johnston 《Urban geography》2013,34(7):1064-1066

In this paper, we explore a “grassroots” neighborhood revitalization effort engendered at the national scale without regard to local geographies of race and class. Specifically, we examine the Harambee Great Neighborhood Initiative, convened by the well-known nonprofit Habitat for Humanity together with Milwaukee’s Local Initiatives Support Corporation, in Milwaukee, Wisconsin. Drawing from participant observation, analysis of print and digital media, volunteer surveys, and interviews with area residents and local nonprofit representatives, we demonstrate the ways in which the six-year program of planning and neighborhood development was conceived and driven by an extra-local nonprofit with significant blind spots to local and organizational politics of race and without sufficient collaboration with the Harambee community. Our analysis points to the importance of race in nonprofit governance and community revitalization efforts. Moreover, we contribute to urban geographic scholarship on nonprofit governance by examining the dynamics of privilege, inclusion, and exclusion as they relate to practices of engagement and volunteerism in nonlocal “grassroots” projects.  相似文献   

WAGE RATES,OCCUPATION STAFFING PATTERNS,AND THE LOCATION OF THE COMPUTER AND SEMICONDUCTOR INDUSTRIES: SOME TESTS OF A CITY-SIZE,INDUSTRIAL LOCATION SORTING MODEL     

《Urban geography》2013,34(4):348-374

This research first develops a paradigm relating technology adoption, plant function, and location in different areas. It then examines empirically some of the paradigm's postulates dealing with occupation staffing patterns and wage rates in headquarters and production plants in different size cities and regions of the country using survey data. The research found that plants in large cities, headquarters plants, and plants in innovative regions paid higher wages than plants in small cities, production plants, and those in innovation-lagging regions. Headquarters plants and plants in large cities and innovative regions had a significantly larger number of scientists, engineers, and technicians on their staffs but few production workers. Production plants and those in small cities and towns and lagging regions had few professional workers but a significant number of production workers. For all types of plants an inverse relationship existed between plant size and city size. The postulated direct relationship between plant size and wage rates was not clearly evident in the survey data except for low skilled occupations. Neither was the relationship clearly evident in the U.S. Census data for the computer and semiconductor industries, as it was for total U.S. manufacturing.  相似文献   

Beyond Gentrification: Mobilizing Communities and Claiming Space   总被引：1，自引：0，他引：1  

《Urban geography》2013,34(5):437-457

During the 20th century, neighborhood change and the displacement of low-income residents from their homes has occurred in a variety of ways from the demolition of entire areas to more recent revitalization efforts emphasizing the building of community and new governance structures. In this paper, I argue two interrelated points. First, whereas economic displacement of low-income people from their homes and neighborhoods is one effect of neighborhood revitalization initiatives, there is a wider set of factors that constitutes the marginalization, displacement, and exclusion of certain population groups from effectively making claims on neighborhood space. Second, in an era of neoliberalization, whereby civil society is expected to play a larger role in neighborhood governance and the provision of social welfare, the formation and activities of neighborhood-based communities, and their relation to state and market forces, have become increasingly important factors to examine. In this article, I address these areas of inquiry through a case study of a neighborhood revitalization initiative in Chattanooga, Tennessee that has been under way since 1998.  相似文献   

Sense of Place in Hamilton,Ontario: Empirical Results of a Neighborhood-Based Survey   总被引：1，自引：1，他引：0  

《Urban geography》2013,34(7):905-931

Although the concept of sense of place has a long history in the social sciences, relatively few studies have attempted a quantitative analysis of sense of place at the neighborhood level. This study reports on the empirical findings of a sense of place survey developed and tested in two contrasting neighborhoods in Hamilton, Ontario, Canada: Southwest Mountain, an upper-middle-class suburban neighborhood and Northeast Industrial, a lower-income, working-class neighborhood located in the heart of the city's industrial district. The principal objective is to assess the relationship between sense of place and the socio-demographic characteristics of residents living in neighborhoods of very different socioeconomic status. This study also introduces a method for calculating a neighborhood sense of place score derived from a fully tested, validated survey instrument. It was found that sense of place was strongest in Southwest Mountain, and among seniors, long-term residents, unmarried people, and immigrants. In addition, residents with a lower level of education and those in the unpaid labor force had a stronger sense of place.  相似文献   

Neighborhood size and spatial scale in raster-based slope calculations     

Jing Gao  James E. Burt  A-Xing Zhu 《International journal of geographical information science》2013,27(10):1959-1978

Raster-based slope estimation is routine in GIS. Like many other terrain attributes, the slope at a location is determined from elevations of surrounding cells. This spatial extent – ‘neighborhood size’ – is often treated as the ‘spatial scale’ of the calculation. In fact, neighborhood size and spatial scale are two connected yet different concepts, but few studies have investigated the relationship between them. The distinction is important because neighborhood size is under user control whereas spatial scale is merely implicit in the computational method. This article attempts to clarify and provide a more precise meaning of the two terms by considering slope operators from the standpoint of the frequency (or wavenumber) domain. This article derives analytical expressions for the amplitude response functions of four popular slope estimators. These are used to characterize the individual methods and also to show that the neighborhood size and spatial scale of a slope calculation are not numerically the same. In fact, because there is no single spatial scale that can be unambiguously associated with a given neighborhood size, neighborhood size cannot be an adequate indicator of spatial scale. Furthermore, this article shows that different indices of ‘scale’ yield different impressions about the action of a slope estimator and its response to changing neighborhood size. Therefore, it is necessary to examine the amplitude response function when investigating the spatial scale. The article also provides guidance for GIS practitioners when selecting a slope estimation method.  相似文献

A geographic perspective is utilized to test the hypothesis that the legal labels homicide and assault represent essentially similar behaviors. The data base describes some 1200 homicide and 32 000 serious assault victimizations in Dallas, TX, for 1981–85. Detailed comparisons across urban neighborhoods (differentiated by socioeconomic status) examine the demographic, temporal, locational, and weapons characteristics of both types of serious violence. The analysis indicates strong congruence between the offenses with respect to most attributes, implying that violence data should be classified differently for behavioral analyses.  相似文献   

PATRIMONY OF THE SEA AND FISHERIES DEVELOPMENT IN LATIN AMERICA     

《The Professional geographer》2013,65(4):421-424

Data from transportation studies are used to examine changes in accessibility to employment opportunities in the Milwaukee urban area from 1927 to 1963. Low-status areas of the city tended to experience the greatest decreases in employment accessibility compared with other parts of the urban area. Furthermore, increasing levels of employment accessibility were associated with greater amounts of new housing, whereas decreases in housing vacancies and population occured in areas with declining accessibility to employment.  相似文献

社会贫困是对居民的社会保障和福利的享有情况、社会参与和融合等生活状况的测度。利用中国3 大典型地域、6 个代表城市、3 类邻里的1809 份个体问卷调查数据, 本文选取13 个相关指标, 判定个体是否处于社会贫困状态, 利用回归模型探究其影响因素, 并分析社会贫困现象在不同邻里、不同城市集聚的分异特征。研究发现, 6 个城市间的社会贫困集聚程度顺序为东部、中部和西部;3 大类邻里中, 社会贫困在城中村表现最为明显, 内城居住区次之, 企业配套居住区最低。中国城市居民是否处于社会贫困状态是体制(户口类型) 和家庭(教育程度、年龄等) 因素共同作用的结果。代表体制因素的户口类型对3 类城市的社会贫困均起到影响, 东中部城市中家庭因素也有一定作用。体制因素对城中村的社会贫困起显著影响, 而家庭因素在内城居住区和企业配套居住区中作用更大。  相似文献   

非线性模型参数估计的大洪水解算方法
