Growth, distribution and rank stability of urban settlements in Greece.

"This paper aims at analyzing the structure of the system in Greece of urban settlements, from 1870 to 1981. It is based on a study by the author concerning the process of urbanization and the problems of the 'residential subsystem' in countries of intermediate development with special reference to Greece. The analysis takes as sole indicator of the evolution of the urban centers network, the long term variation of population of urban settlements in Greece and as tools of analysis, the Rank-Size Rule (RSR) and Hoover's Index." Distinctions are drawn between the urban settlement patterns in the pre-capitalist and capitalist periods, the latter being marked by an unbalanced hierarchy dominated by Athens and without medium-sized cities, other than Thessaloniki.

Population decentralization within metropolitan areas: 1970-1980.

Using a data set that maintains geographic and fiscal continuity over time and across a sample of major U.S. metropolitan areas, the authors identify factors of economic and population decentralization that affected central city areas between 1970 and 1980. The problems of annexation are resolved by estimating population changes for central cities and suburban areas with constant 1980 boundaries, and by calculating fiscal variables from overlapping jurisdictions by city area as opposed to municipal city government only. "The empirical investigation supports the view that demographic and housing stock variables seem to have had a greater impact on decentralization than central city-suburban fiscal differences."

Estimation of megacity growth: simple rules versus complex phenomena.

"The growth of large urban aggregates (megacities) is analogous to the development of self-organized structures known in physics. Using empirical data about changes in the built-up areas of different cities as input, the self-organizing model employed here suggests that megacities evolve towards a hierarchical form of spatial organization, and provides estimates of the size of subclusters that compose the urban aggregate.... The model has been validated by reproducing the evolution of the Berlin area over a period of 35 years (1910-45). Using the same assumptions, the evolution of the built-up area of Daegu (Korea) is simulated up to the year 2010."

On population growth of cities in a region: a stochastic nonlinear model.

"A stochastic migration model describing the population dynamics in a region is investigated. The model is described by a pair of coupled differential equations with state-dependent stochasticity. Explicit expressions for the time evolution of the moments for the population sizes of cities are obtained from the Fokker-Planck equation. The Stratonovich calculus is employed in the analysis."

Loose-coupling a cellular automaton model and GIS: long-term urban growth prediction for San Francisco and Washington/Baltimore.

"Prior research developed a cellular automaton model, that was calibrated by using historical digital maps of urban areas and can be used to predict the future extent of an urban area. The model has now been applied to two rapidly growing, but remarkably different urban areas: the San Francisco Bay region in California and the Washington/Baltimore corridor in the Eastern United States. This paper presents the calibration and prediction results for both regions, reviews their data requirements, compares the differences in the initial configurations and control parameters for the model in the two settings, and discuses the role of GIS in the applications."

Racial and ethnic succession in four cities.

"The concept of succession is well established in both ecological and economic models of urban residential change, yet much remains unknown about the determinants of succession in urban neighborhoods. Employing longitudinal census tract data for four [U.S.] cities, this article predicts racial composition of neighborhoods as a function of earlier-period racial, ethnic, socioeconomic, and physical characteristics. There is support for aspects of the ecological and filtering models of succession, although many elements of the process are not generally applicable across time and place."
