The major objective of the paper is to estimate regional utility levels based on interregional migration data. Three stylized facts concerning migration behavior are revealed by examining long-term Japanese data on interregional migration. Based
on the stylized facts and the inconsistency problem, an operational model is formulated and interregional utility differentials are estimated. These differentials converged until the late 1970s. The utility estimates are highly correlated with the per capita real
Utilities, land-use change, and urban development : brownfield sites as cold-spots of infrastructure networks in Berlin
Drawing on recent research into the spatial strategies of utility companies, after liberalisation and privatisation, the A. identifies disused industrial sites as cold-spots of infrastructure systems where energy and water consumption has recently
collapsed. He analyses the challenges facing Berlin's major utilities as a result of shifting patterns of resource consumption and overcapacity. He then examines the responses of the utilities in the context of recent institutional changes to infrastructure.
A new attempt at an ecological classification of land utilization systems
After a brief review of previous classifications, the A. advocates an approach for an ecologically-based classification of utilization systems, consisting of two elements : one describing the productive environment, and the other describing the main
Foldhasznositasi térképezés Bodrogkeresztur térségében. (Land utilization mapping in the Bodrogkeresztur region)
The most famous well-known historical wine-growing region of Hungary is Tokaj-Hegyalja. In 1975-1976 the AA. carried out land utilization mapping in the course of which agricultural growing has been surveyed on a map of scale 1:2880. (CK).
On the possible utilization of Camelops by early man in North America
Of 25 fossil assemblages examined, 2 might be examples only of geological contemporaneity of humans and Camelops| 2 might indicate behavioral association of humans and Camelops bones| and 2 might indicate actual human utilization of Camelops

Standort-und Nutzungsprobleme mineralischer Rohstofflagerstätten in Weltmasstab. (Location and utilization problems of mineral raw material deposits in a global scale)
An essential supposition for the effective utilization of deposits is their geologic-ecological valuation. Four groups of deposits with different value, quantity and quality are distinguished. The territorial effects of the historical location
are shown, especially by complex utilization of the existing deposits. (HL).
