Dynamic Central Place Theory: Results of a Simulation Approach

A dynamic central place theory is formulated as a simulation model in which retail activities, described by cost equations, and consumers, described by spatial interaction equations, interact to generate a central place system. The behavior of the model is then examined. Simulation results show that the basic character of the system—whether it is agglomerated or dispersed—depends primarily on a single parameter in the interaction equation, and only secondarily on the specification of the cost function. The results are highly robust in that they are largely independent of the initial sizes and locations of centers, and even independent of the type of interaction equation used. The patterns generated appear plausible.     

Down Little Lon: An Introduction to the Casselden Place Archaeological Excavations, Melbourne

In 2002 Melbourne’s Casselden Place excavation provided a window into the urban past opened by an innovative relationship between the development industry, heritage consultancy and La Trobe University. The project demonstrated that with the support of consent authorities and the co-operation of the development industry, collaborations between the academic world and heritage consultants could be highly successful. The Casselden Place Project made a significant contribution to the ‘slum debate’ in Australia and delivered an enhanced understanding of the cultural, social and scientific significance of an inner-city block, and shed new light on a notorious chapter in the city’s history.     

Advancing Policy Theory with Cultural Theory: An Introduction to the Special Issue

Cultural Theory (CT) is a constructivist theory, developed by Mary Douglas, Aaron Wildavsky, and others, that seeks to participate in the positivist project of discovering, explaining, and predicting regularities in human behavior. Special Issue contributions and this introduction suggest some ways in which this theory can help advance policy studies. One way CT can help is by further specifying other approaches to policy theory. Thus, Hank Jenkins‐Smith and his collaborators argue (and with respect to belief systems demonstrate) that the theory can be used to specify belief systems, coalitions, and causes of policy change in the Advocacy Coalition Framework (ACF); Rob Robinson uses CT to specify further both sources of resistance to policy change and sources of dramatic policy change in Punctuated Equilibrium Theory (PET); and Christopher Weare, Paul Lichterman, and Nicole Esparza use the theory to specify sources of collaboration in policy networks as well as sources of network dissolution. Other contributors argue and/or demonstrate that CT can help specify the culturally pluralized conditions for successful policy deliberation, the cultural sources of policy narratives, and how cultural biases are likely to interact with policy frames. This Special Issue invites policy scholars to consider how the theory might help advance their research interests and the field.     

The Fractal Theory of Central Place Geometry: A Diophantine Analysis of Fractal Generators for Arbitrary Löschian Numbers

We develop material to determine whether or not an arbitrary number is Löschian; the procedure embodied in the theorems achieves the desired result more swiftly than do previous solutions to this problem. The correspondence between a partition of the central place lattice and a quadratic form permits the rapid determination of the lattice coordinates of an arbitrary Löschian number and of the exact shape of a single fractal generator used to form an entire central place hierarchy associated with an arbitrary Löschian number. Central place hierarchies may be generated geometrically using a single shape applied initially to a hexagon and subsequently, scaled appropriately, to resultant polygons. Fractional dimensions of arbitrary central place hierarchies, measuring their “space-filling” characteristics, follow naturally from this general procedure.     

Spaces of the political*

In changing geographic locations, metaphorically or otherwise, perceptions change. Drawing inspiration from ancient Peking rather than Leo Strauss’ Athens and Jerusalem changes the compass points of political theory. This is because it moves the centre of gravity away from the tension of reason and revelation toward a city built upon another way of approaching the world, through the channelling and harnessing of vital energy flows, known as qi. Peking is designed, through fengshui, to channel the vital energy know as qi away from intensities and toward productive (harmonious) ends. How have we moderns channeled and harnessed such (political) intensities? This work traces the flow of energy as it takes on modern political forms, expressed through the built environment. Taking the nineteenth-century’s Crystal Palace and a Maoist Museum as contrasting examples, it illustrates the way in which the built environment channels and transforms energy. In terms of the political, it is the dissipation or intensification effect of these machines that becomes the defining characteristic of difference between these two different political worlds. As modern machine-technologies, these two examples also shine a light on the ways ‘modernity’ has encountered and dealt with the telluric.     

GeoDa : An Introduction to Spatial Data Analysis

This article presents an overview of GeoDa™, a free software program intended to serve as a user-friendly and graphical introduction to spatial analysis for non-geographic information systems (GIS) specialists. It includes functionality ranging from simple mapping to exploratory data analysis, the visualization of global and local spatial autocorrelation, and spatial regression. A key feature of GeoDa is an interactive environment that combines maps with statistical graphics, using the technology of dynamically linked windows. A brief review of the software design is given, as well as some illustrative examples that highlight distinctive features of the program in applications dealing with public health, economic development, real estate analysis, and criminology.     

The Place of Regional Economic Geography in the System of Geographical Sciences

The author holds that regional geography cannot be regarded as an independent geographic discipline because it lacks its own system of laws, such as the natural laws that operate in physical geography and the social laws that operate in economic geography. He agrees with the view that both physical and economic geography fall into theoretical and regional departments, and that regional studies test the localized application of the general laws formulated by the theoretical departments of the two great divisions of geography.
