This article investigates the growth of business services (SIC73) in Michigan and models the relationship between the industry and local economic conditions in metropolitan and nonmetropolitan counties. The research makes four conclusions. First, SIC73 measures explain variance in manufacturing productivity. Second, SIC73 indicators explain variation in manufacturing and overall wages. Third, these relationships vary between metropolitan and nonmetropolitan counties. Despite growth in rural regions, SIC73 indicators more effectively predict wages and productivity in metropolitan counties. Hence, the localized benefits associated with SIC73 industries are more strongly associated with metropolitan economies. Fourth, the interdependencies that have developed between SIC73 industries and the manufacturing sector decrease over time in both metropolitan and nonmetropolitan contexts. The article concludes with suggestions for future research. 相似文献

Under the framework of ecological civilisation, the formulation of territorial spatial planning(TSP) and improvement of spatial governance systems are of great practical significance. Since the founding of the People’s Republic of China, land-use planning(LUP) has experienced profound changes, and tremendous research efforts have been made in that field. However, systematic studies on LUP history are scarce.To bridge the existing gap, this study traced back to the emergence of LUP, described its... 相似文献

A unique feature of migration in China is its two-track system, one consisting of permanent migration and temporary migration. This article examines whether and how hukou reforms and the maturation of migration streams since the 1980s have changed the two-track system. Using data on interprovincial migration from the 1990 and 2000 censuses, our empirical analysis focuses on the differentials between permanent migrants and temporary migrants and their changes over time. We document the size, migration reasons, and selectivity of migrants, and we evaluate the determinants of the dichotomy between permanent migrants and temporary migrants via logistic regression models. Our findings show that between 1990 and 2000 the gaps between interprovincial permanent migrants and temporary migrants did not narrow but in most aspects had widened. There is little evidence that hukou reforms have lowered the barriers to urban citizenship. At the same time, a larger spectrum of the rural population has joined the temporary migration streams. The net result is a persistence of the two-track migration system, where permanent migrants increasingly assume the position of social and economic elites and temporary migrants are the disadvantaged and disenfranchised. 相似文献

Drawing on the insights of the geography, structural, and social movement literature this study analyzes the interactive effects of structure, space, place, and agency on patterns of collective action in Long Beach, California. Long Beach and Los Angeles occupy the same regional landscape with similar economies, yet the logic of collective action varies considerably. It is argued that preceding 1960, pro-business elites in Long Beach allied with their Los Angeles counterparts to spatially restrict labor organizing and foster patterns of noncontiguous interdependencies within and among labor and community groups. Through violence, cultural references, local and extralocal political policies, and regional coalition building before 1960, the Long Beach ruling elites fragmented the labor and community sector and inhibited the emergence of an organizational infrastructure necessary to foster community-based change after 1960. The legacies of this period are reflected in a fragmented labor and community sector set against a powerful ideologically driven, business-led opposition. 相似文献

Crime is both a factual and perceptual component of the urban landscape, seemingly both a societal pathology and the consequence of economic disparity between social groups. Crime has a spatial structure that can be revealed by mapping. Urban crime has a spatial multiplier effect that changes the values and perceptions of how people see urban space, and which jeopardizes the quality of life of a city's inhabitants. In this research we examine the question of whether the geography of actual criminal acts is echoed by peoples' perceptions of crime, what might be termed their “spaces of fear”. We ask how the fear of crime is associated with reported urban crime. Urban crime incidents have been increasing in Viçosa, Minas Gerais, Brazil. We assembled crime information about Viçosa from two sources: first, crime as reported to the police and second, crime as perceived by city residents and measured by surveys and interviews. Reported criminal acts reveal a clustered geography, focusing particularly on the Downtown area, where there is a concentration of urban wealth and potential victims are more numerous. Offenses against property were focused on Downtown, while offenses against the person were located mostly in peripheral areas. The widespread feeling of insecurity in the city's neighborhoods, reflecting the fear of becoming a victim of violence and crime, was common throughout the city. Results confirmed the conclusion of past studies showing that the fear of violence and crime are not directly related to increasing numbers of criminal reports. Sites with higher incidence of crimes are not places with higher levels of fear. Rather than being geographically explainable “spaces of fear”, the spatial distribution of the fear of violence and crime appears to be unrelated in Viçosa, and neither is clustered or dispersed in any measurable way. 相似文献

Fast food restaurants and liquor stores—vice stores—have been shown to be more prevalent in predominantly Black and low income U.S. neighborhoods, and are associated with a number of health risks and social ills. The purpose of this study was to investigate in the City of Chicago vice store density and spatial distribution as a function of racial, socioeconomic, and other population characteristics; to examine spatial clustering among these outlets; and to study how store turnover follows population change over a 13-year period. We used spatial point process analysis to fit linear and non-linear models for the intensity function of stores. Spatial clustering was estimated using the K function. We found heterogeneous associations between stores and population characteristics, with the most consistent finding being a positive association between percent Black and liquor store exposure. A high degree of spatial clustering was evident, and liquor stores were more likely to stay in business over time than fast food restaurants. However, when liquor stores closed, they were more likely to be replaced by non-vice businesses. Results suggest that vice stores are associated with lower positions in racial and socioeconomic hierarchies, and this patterning is often durable over time. 相似文献

This research tests the spatial mismatch hypothesis by comparing the employment probabilities of central city versus suburban African American males in nine metropolitan areas. Treatment effects models are used to control for the effects of both individual characteristics and residential self-selection on the probability of employment. A positive effect of suburban residential location on employment is found for the residents of Dallas, Los Angeles, New York, and Washington, while no effect is found for the residents of Cleveland, Houston. Jackson, Memphis, and Newark. The general conclusion to be drawn is that the spatial mismatch effect is contingent on the particular characteristics of each metropolitan area. Preliminary analysis shows that metropolitan areas with a spatial mismatch effect are large in terms of total population and total land area, and have less efficient transportation systems. 相似文献

Landing a rescue helicopter in a wilderness environment, such as Yosemite National Park, requires suitable areas that are flat, devoid of tree canopy, and not within close proximity to other hazards. The objective of this study was to identify helicopter landing areas that are most likely to exist based on available geographic data using two GIScience methods. The first approach produced an expert model that was derived from predefined feature constraints based on existing knowledge of helicopter landing area requirements (weighted overlay algorithm). The second model is derived using a machine learning technique (maximum entropy algorithm, Maxent) that derives feature constraints from existing presence-only points; that is, geographic one-class data. Both models yielded similar output and successfully classified test coordinates, but Maxent was more efficient and required no user-defined weighting that is typically subject to human bias or disagreement. The pros and cons of each approach are discussed and the comparison reveals important considerations for a variety of future land suitability studies, including ecological niche modeling. The conclusion is that the two approaches complement each other. Overall, we produced an effective geographic information system product to support the identification of suitable landing areas in emergent rescue situations. To our knowledge, this is the first GIScience study focused on estimating the location of landing zones for a search-and-rescue application. 相似文献

Discussions of East Asian developmental states and Asian values discourse have been deformed by national-territorial frameworks that limit scholars' ability to highlight transnational phenomena. Such limits can be overcome by adopting a “Pacificist” perspective, one that highlights the transnational collaborative efforts of Pacific ruling class members, from both Asia and the United States. Such a Pacificist approach has the virtue of highlighting phenomena of transnational class formation that help account for the emergence of both developmental states in East Asia and Asian values discourse, and it also suggested the importance of attending to other kinds of emerging actors in Asian development politics, such as labor and democracy movements. 相似文献

This paper outlines the results of mixed-methods research on Māori and cycling. Our findings suggest that Māori cycle at similar rates to Pākehā (NZ European); however conditions may differ, possibly indicating higher levels of “necessity cycling” amongst Māori. Māori experience similar barriers to cycling, including a lack of suitable cycling infrastructure, but these occur against a backdrop of stark social, economic and transport-related inequities. Particular barriers for Māori may include inflexible work conditions, concerns about neighbourhood safety, inadequate provision for social cycling, and lack of access to places of importance to Māori. We identify potential solutions, including more whānau-friendly and culturally safe cycling infrastructure, and cycling programmes designed around Māori commitments to whanaungatanga and kaitiakitanga. 相似文献

Rural areas in developed economies are becoming increasingly multi-functional in that their character is being shaped by a mix of production, consumption and conservation values. Agriculture may remain the dominant land use, but many landholders do not see themselves as farmers by occupation. Researchers have demonstrated that occupational identity influences land use and management. However, efforts to explore the influence of occupational identity often rely on surrogate measures and have largely ignored identity theory. We build on research demonstrating that collective identity theory can be used to develop a valid and reliable measure of farmer identity and to then classify rural landholders across a natural resource management (NRM) region. The contribution of this paper is to explain how that measure of farmer identity can be mapped and then demonstrate the relevance of doing so for regional NRM in Australia. As expected, farmer identity varied across the case study region with distance from urban centres, and across different environmental assets. Those findings should lead to a more targeted approach to landholder engagement in NRM. We suggest that farmer identity (i.e. farmer-collective occupational identity construct; F-COIC) might provide a next step for responding to the challenges of interpreting and mapping multi-functionality. 相似文献

ABSTRACTThis paper is a broad review of green infrastructure theory and practice relative to urban sustainability and the space for geographers in these discussions. We use examples from various urban sustainability plans to highlight ways in which green infrastructure is being conceptualized and implemented. We explore how geography contributes research on green infrastructure as well as the emerging practices as seen within sustainability plans. We identify four areas in which geographers can influence both green infrastructure theory and practice: 1) scale; 2) mapping distribution; 3) sensitivity to place and locale; and 4) equity and access. We conclude that in these areas geographers have tremendous opportunity contribute more deliberately to sustainable urbanism. 相似文献

This study is motivated by insufficiencies in two areas in the literature. First, some technical barriers have hindered investigations of changing job–housing patterns over time. Second, traditional dichotomous studies (black–white) of ethnically divided commuting patterns are insufficient to paint the big picture of such dynamics in a multiethnicity metropolitan area. This research fills the gap by presenting an approach to the spatio-temporal analysis of commuting patterns by ethnicity. A case study is performed to track changing commuting patterns for whites, blacks, and Latinos in Atlanta over the last two decades. The results shed light on our understanding of the changing job–housing dynamics, particularly that of Latinos. 相似文献
