Policymakers pursue a range of strategies aimed at diversifying neighborhoods despite research indicating the complicated and potentially damaging results of these efforts. One increasingly common approach is to incorporate the arts into planning efforts in the hope of enhancing diversity and catalyzing positive neighborhood change. Using data from the Cultural Data Project, the authors determine where newly established New York City arts organizations locate in terms of neighborhood racial, income, and industry diversity. They then analyze how diverse contexts interact with an arts presence to impact neighborhood economic health over time. They find that neighborhoods with high levels of racial diversity and low levels of income and industry diversity benefit most from an arts presence. However, the arts are attracted predominantly to neighborhoods with moderate levels of racial diversity and high levels of income and industry diversity. This complicates the use of the arts as a tool in urban revitalization policy.  相似文献

Cities are oftentimes seen as undergoing a process of “emergence” in the “new economy.” However, this process has largely remained empirically underdetermined. This article examines the intra‐city geography of emerging businesses in newly dominant sectors of the urban economy. The change in dominant sectors coincides with a shift towards small‐ and medium‐sized businesses, creating new economic opportunities for urban residential areas. The residential neighborhood is introduced as a place where supply and demand side drivers operate to attract or limit such new economic activity. Allen Scott's perspective of the cognitive‐cultural economy is used to analyze which neighborhoods are flourishing sites of the cognitive‐cultural sectors. His perspective on industries that are on the rise in urban environments and their growth potential proves very valuable. Social demographic characteristics on the level of the neighborhood are used as predictors of the composition of the local economy. The analyses show that in particular wealthy, gentrified neighborhoods are more prone than others to becoming “hubs” of the cognitive‐cultural economy. However, disadvantaged neighborhoods may under certain conditions serve as incubators for business start‐ups as they offer low‐rent office spaces. This has important consequences for their future economic growth potential as well as the distribution of successful businesses in the city.  相似文献

ABSTRACT: The purpose of this article is to evaluate the degree to which three ecological models can predict the direction of neighborhood change. Three models —the life cycle, arbitrage, and composition—are commonly found in the literature on neighborhood change, but each focuses on a different aspect of this process. To date, researchers have evaluated these models individually, but few have compared their predictive ability. Using census tract data from Cleveland, Ohio, this study conducts a regression analysis to evaluate the efficiency of each model. The lifecycle model had the greatest predictive value, but none of the models performed well. The state of Cleveland's industrial-based economy combined with the diminished federal role in urban development were identified as contributing factors to a declining inner-city environment. The condition of Cleveland's housing market was reflected in the models.  相似文献

Neighborhood‐focused activism is one way residents enact their vision for their community. This study examines the neighborhood socioeconomic antecedents of participation in neighborhood‐focused activism in a diverse sample of residents of Chicago neighborhoods to test three theories of neighborhood socioeconomic context and participation: (1) affluence affords participation, (2) activism addresses neighborhood needs associated with disadvantage, and (3) socioeconomic inequality creates contention that necessitates participation. Measuring neighborhood socioeconomic status as two unique dimensions—neighborhood affluence and neighborhood disadvantage—and accounting for both individual and neighborhood characteristics, I find support for each theory. Neighborhood socioeconomic context matters for participation, regardless of individual socioeconomic characteristics. Only when these three perspectives are considered jointly can they fully capture the socioeconomic context of participation in neighborhood‐focused activism.  相似文献

It is the author's contention that community control movements of the 1960s were unable to fulfill their militant objectives due to their lack of politically critical resources. As a result, these organizations were forced to moderate their objectives or incur the wrath of their donors. This article provides a brief history of the movement and an analysis of the consequences of resource dependency (i.e., the need of these groups to seek resources from government, corporations, and the philanthropic sector). The author concludes that the participants, if they are to have any hope of becoming successful, must maximize their own resources. Such maximization might make community control organizations less dependent on outside donors (whose interests may conflict with those of the group), giving them greater freedom to realize their objectives.  相似文献

It is important that students of urban life develop an understanding of the dynamics by which community associations influence the quality and quantity of public services available in their neighborhoods. Employing collective goods theory to analyze the activities of neighborhood organizations suggests that their efforts to influence public services may usefully be conceptualized in terms of three primary roles. Community associations act as consumers' cooperatives seeking to secure public services from other organizations, as alternative producers of desired services, and as organizers of citizens' coproductive efforts whereby service levels are determined through the joint efforts of neighborhood residents and public service personnel. The three roles differ significantly in the effectiveness and efficiency with which citizens can employ them to secure services, and require different resources from the community associations. The design of governmental arrangements for service delivery are closely related to the availability and effectiveness of the three strategies and must be considered as part of any effort to enhance citizens', role in public service delivery.  相似文献

Many studies have examined the impact of the size of the neighborhood minority population on prejudicial attitudes of majority residents. However, few studies have investigated how residents of different ethnic origins evaluate different ethnic outgroups based on the shares of these particular ethnic outgroups in their neighborhood. Based on the belief congruency theory and social identity theory, we propose that the effect of outgroup size on outgroup attitudes depends on the socioeconomic and cultural differences between ethnic groups. Multilevel analyses of Dutch survey data gathered among Turkish, Moroccan, Surinamese, Antillean, and native Dutch residents indicate that for most groups outgroup attitudes are not influenced by the share of the particular outgroup in their neighborhood. For some ethnic groups, however, the size of a particular outgroup is associated with less positive attitudes toward that outgroup. Differences in the effect of outgroup size on outgroup attitudes only partly correspond with cultural differences and socioeconomic status differences.  相似文献

ABSTRACT: This study examines neighborhood cohesion in a racially and economically integrated neighborhood in Dayton, Ohio. The authors compare results of surveys conducted in 1984 and 1990. This was a period when the neighborhood witnessed a number of significant changes, including a marked increase in African-American residents, a decrease in homeownership and an increase in vacant units, and an increase in crime. Neighborhood cohesion appeared to remain strong in 1990, although not as strong as in 1984. Despite these changes, appreciation for racial diversity increased significantly during the period, most markedly among new white residents of the area.  相似文献

ABSTRACT This paper seeks to develop an understanding of the most significant determinants of spatio-temporal patterns of private capital accumulation in Canadian regions by focusing on both economic and political attributes of the regional investment context. Economic variables include spatial variations in profitability of production. labor costs, and aggalomeration economics, while the chief political dimension is the extent of union organization and militancy within the regional labor force. Analysis of provincial manufacturing activity1 investigates the relative importance of economic versus political variables in shaping the histories of investment and technical change in individual provinces from the mid-1980s to the present.  相似文献

Increasing water shortage and water pollution issues have attracted people to seek an integrated water management approach. This paper presents an integrated water management model at the industrial park level by employing a case of TEDA. Such a model is an overall management model for optimizing water resources within an industrial park, seeking potential water reuse among industries, incorporating the size and cost of reclaimed wastewater delivery systems. The main focus of this paper is to test how pricing strategy can influence water reuse scenarios by doing a cost sensitivity analysis. The results Indicate that when being set at the correct level, increased water charges could help reduce freshwater use and wastewater discharge, while covering administrative costs, financing environmental improvements (e.g. cleaner production), or subsidizing the operation of the wastewater treatment plant and the maintenance of freshwater infrastructure, therefore, providing water reuse incentives for water users within an industrial park.  相似文献
