Patterns of residential segregation within a metropolitan ghetto

Patterns of Residential Segregation

The spatial distribution of income shapes the structure and organisation of cities and its understanding has broad societal implications. Despite an abundant literature, many issues remain unclear. In particular, all definitions of segregation are implicitely tied to a single indicator, usually rely on an ambiguous definition of income classes, without any consensus on how to define neighbourho...

Residential Segregation and Neighborhood Conditions in U.S. Metropolitan Areas

Spatial Patterns of Residential Segregation: A generative Model

Residential segregation is an explicitly spatial phenomenon that emerges from the interaction of many individuals and displays markedly different global patterns depending on specific socioeconomic contexts. This paper presents a generative model of socioeconomic segregation that reproduces regular macro-level patterns of the phenomenon through the specification of a minimal set of parameters t...

A mathematical model of segregation patterns in residential neighbourhoods

A mathematical model is proposed which describes the dynamics and the spatial distributions of two population groups, where migration is driven by considerations of socioeconomic status. The model associates segregation with instabilities of spatially uniform mixed population states. These instabilities lead to a wide range of segregation forms including: (a) variable (weak) segregation where t...

Variability in carotid endarterectomy practice patterns within a metropolitan area.

BACKGROUND AND PURPOSE Previous clinical studies have suggested that patients with carotid stenosis with high surgical risk features may fare better with carotid artery stenting or aggressive medical therapy. The extent to which carotid endarterectomy is still being performed in this group of patients is unclear. METHODS A retrospective audit was performed among 4 hospitals over a 2-year peri...
