Abstract. This paper extends our previous efforts to (de)lineate contemporarydivisions between poststructuralist and spatial analytic, or scientific, approaches in geography. We adopt the format of a dialogue between a hypothetical spatial analyst (SA) and a poststructuralist (PS). Their exchange covers, among other items, the differing stances of these approaches to epistemology, ontology, research questions and methods, and the concept of 'context'. We also further develop the concept of the 'epistemology of the grid', which we define as the spatialization of categorical thought. We link this epistemology to two others, Cartesian perspectivalism and ocularcentrism, arguing that their realization in social practice is generative of social order.

Spatial Scale and Population Assignment Choices in Environmental Justice Analyses1

Abstract
Environmental justice laws protect certain populations against discriminatory actions that may result from a myriad of enterprises, including transportation activities. Previous environmental equity studies examining the effects of transportation-engendered externalities have been criticized on several points, including (1) that the choice of a reference population for comparison to the criterion variable may influence the outcome of research results and (2) that the selection and use of inappropriate methodologies intended to identify and characterize populations may foreordain research outcomes. This article examines the potentially confounding effects of selected spatial scale and population assignment strategies as applied to a study of excessive noise levels at a large Midwestern airport, finding that reported outcomes can vary significantly as a function of methodological choices.
How We Watch the City: Popularity and Online Maps

ABSTRACT
One way of conceptualizing physical spaces is to look at
where people notice, remember, or note them. Computer-
assisted methods give us new tools based on implicit, rather
than explicit, data about how users have examined and
travelled online through cities. “Hotmap” is a tool that
visualizes how people have used maps.live.com, an
interactive mapping service, looking at what parts of the
maps they find most compelling.

Exploring Changes in Income Clustering and Centralization during the 1990s

This article employs a new "spatial ordering index" to describe and explain changes in the degree of income clustering and centralization within U.S. metropolitan areas during the 1990s. The results suggest that while the spatial pattern of household income became more decentralized and less clustered during the 1990s, the patterns established as of 1990 were highly persistent over the decade. Factors associated with metropolitan area size and growth affected changes in both the degree of centralization and the degree of clustering. Although traditional determinants of suburbanization were associated with increases in income decentralization during the 1990s, densely developed cities with an increase in the percentage of white residents saw increases in income centralization during the decade. Furthermore, changes in the patterns observed were shaped by various policy influences, including the number of Low Income Housing Tax Credit units, urban containment policies, and the degree of local government fragmentation.
