Recent empirical research, and a simple stochastic modeling exercise, suggest that affluent suburban communities are at increased risk for the diffusion of HIV from present inner city epicenters, while the 'core group' construct of sexually transmitted disease theory suggests, somewhat...

Steep socioeconomic hierarchy in post-industrial Western society threatens public health because of the physiological consequences of material and psychosocial insecurities and deprivations. Following on from their previous books, the authors continue their exploration of the geography of early...

The March, 1978 issue of Management Science carried a paper by Jan M. Chaiken titled "Transfer of Emergency Service Deployment Models to Operating Agencies" which purported to describe the successful implementation of, among other things, fire service management models developed by the Rand...

Quantification of the relationship between community-level chronic stress from neighborhood conditions and individual morale has rarely been reported. In this work, pregnant women were recruited at the prenatal clinics of Harlem Hospital and Columbia Presbyterian Medical Center in the USA, and...

We compare mechanisms of AIDS diffusion at the county level from five U.S. central city epicenters into their associated metropolitan regions. Four of the five show an expanding 'hollowed out' center of physically and socially devastated, politically and economically abandoned high density...

During the 1970s, New York city experienced an epidemic of housing destruction by contagious fire and building abandonment. This epidemic was triggered by reductions in municipal services, especially fire control, in the poor areas of high population density and aging housing. The rapid loss of...

Generalized Darwinian evolutionary theory has emerged as central to the description of economic process (e.g., Aldrich et al., J Evol Econ 18:577–596, <CitationRef CitationID="CR3">2008</CitationRef>). Just as Darwinian principles provide necessary, but not sufficient, conditions for understanding the dynamics of social entities, so too...</citationref>

Previous work on the asymptotic spread of HIV infection along a low dimensional 'sociogeographic' network--a social network characteristically embedded within a limited geographic area--is extended to explore threshold conditions under which the infection extends widely beyond an initial set of...
