Potential Of Spatial Analysis Of Housing Submarkets In Understanding Residential Segregation, Sungsoon Hwang
Potential Of Spatial Analysis Of Housing Submarkets In Understanding Residential Segregation, Sungsoon Hwang
Sungsoon Hwang
Residential segregation has important implications for social mobility, namely through achievement gap by neighborhoods. The endeavor to unravel processes leading to residential segregation can benefit from empirical analysis of housing submarkets. This paper discusses how spatial analysis of housing submarkets might be useful in exploring patterns and processes of residential segregation. As a case study, housing submarkets in St. Louis and Cincinnati are empirically delineated using fuzzy clustering, and differences in spatial pattern of residential segregation in these two metropoiltan areas are discussed.
Locational Probability For A Dammed, Urban Stream: Salt River, Arizona, William Graf
Locational Probability For A Dammed, Urban Stream: Salt River, Arizona, William Graf
William L. Graf
Data from historical aerial photographs analyzed with a GIS show that river channel change on the Salt River in the Phoenix metropolitan area of central Arizona has been driven by large-scale regional flood events and local human activities. Mapping of functional surfaces such as low-flow channels, high-flow channels, islands, bars attached to channel banks, and engineered surfaces shows that during the period from 1935 to 1997, the relative areal coverage of these surfaces has changed. Flood events have caused general changes in sinuosity of the low-flow channel, but islands have remained remarkably consistent in location and size, while channel-side bars …

Tamarisk And River-Channel Management, William Graf
Tamarisk And River-Channel Management, William Graf
William L. Graf
Tamarisk (Tamarix chinensis, Lour.) an artificially introduced tree, has become a most common species in many riparian vegetation communities along the rivers of the western United States. On the Salt and Gila rivers of central Arizona, the plant first appeared in the early 1890s, and by 1940 it grew in dense thickets that posed serious flood-control problems by substantially reducing the capacities of major channels. Since 1940 its distribution and density in central Arizona have fluctuated in response to combined natural processes and human management. Groundwater levels, channel waters, floods, irrigation return waters, sewage effluent, and sedimentation behind retention and …
Development Of Montane Arroyos And Gullies, William Graf
Development Of Montane Arroyos And Gullies, William Graf
William L. Graf
Field investigations in the Front Range of Colorado, U.S.A., confirm that the spatial distribution of vegetation in watersheds exerts strong control on the entrenchment of streams in the montane zone. When tractive force in channels exceeds threshold values of resistance on the valley floors, cutting of arroyos begins, producing forms that change allometrically. An algorithm based on the Cooke Method for discharge, the Manning Equation for depth of flow, and the DuBoys Equation for tractive force can be used to evaluate force for observed and experimental conditions. In small (<5 km2) basins in the Front Range of Colorado, forces …

Integration And The Negotiation Of 'Here' And 'There': The Case Of British Arab Activists, Caroline Nagel, Lynn Staeheli
Integration And The Negotiation Of 'Here' And 'There': The Case Of British Arab Activists, Caroline Nagel, Lynn Staeheli
Caroline R. Nagel
Immigrant-receiving societies are increasingly emphasizing the need for immigrants to integrate into mainstream life. In Britain, this trend has manifested itself in 'social cohesion' discourses and policies. Discussions about social cohesion have often focused on the residential patterns of immigrant and minority groups in British cities, with the assumption that residential patterns are an indication of social integration. Integration, however, is also a socio-political process by which dominant and subordinate groups negotiate the terms of social membership. We explore the ways in which British Arab activists conceptualize their membership in and responsibilities to their places of settlement; we also consider …
Hidden Minorities And The Politics Of ‘Race’: The Case Of British Arab Activists In London, Caroline Nagel
Hidden Minorities And The Politics Of ‘Race’: The Case Of British Arab Activists In London, Caroline Nagel
Caroline R. Nagel
This paper uses a case study of activists in London's Arab communities to address the marginalisation of certain groups in academic analyses of 'race' and ethnicity. Theorisation of 'race' has become increasingly sophisticated, emphasising the fluidity of racial identities and the contextual specificity of racial ideologies and racialised practices. Yet very few empirical analyses of 'race' stray from the rigid categories of 'race' and ethnicity found in censuses and other official sources. The implication is that only certain groups 'count' as 'racial' and should be analysed in terms of 'race'. Using evidence gathered from intensive interviews with Arab community activists, …
Controlling Influenza A (H1n1) In China: Bayesian Or Frequentist Approach, Dejian Lai, Chiehwen Ed Hsu
Controlling Influenza A (H1n1) In China: Bayesian Or Frequentist Approach, Dejian Lai, Chiehwen Ed Hsu
Chiehwen Ed Hsu
In this article we discuss two approaches to controlling the newly identified influenza A (H1N1) via Bayesian and frequentist statistical reasoning. We reviewed the measures implemented in China as an example to illustrate these two approaches. Since May 2009, China has deployed strict controlling mechanisms based on the strong prior Bayesian assumption that the origin of influenza A (H1N1) was from outside China and as such strict border control would keep the virus from entering China. After more than two months of hard work by Chinese health professionals and officials, the number of confirmed influenza A (H1N1) has increased steadily …
