From 1950 forward, his Central Place Theory was used to restructure municipal relationships and boundaries in the Federal Republic of Germany and the system is still in place today.

In 1929 he resumed graduate studies that led to his famous dissertation on Central Place Theory, which he published as the " Die zentralen Orte in S�ddeutschland " ( The Central Places in Southern Germany ), in 1933.

After the German reunification in 1990, Gera became part of the restored state of Thuringia one of three supra-centres ( " Oberzentren " ) along with Jena and Erfurt according to the Central Place Theory in German regional planning.

He then studied for an MPhil on central place theory and the work of the early economists, completing his formal education in 1970 with a PhD from the University of Nottingham with a thesis on the post-war changes in retailing in selected European regions.

A German hegemony of sorts seems to have taken hold in location theory from the time of von Th�nen through to Walter Christaller's 1933 book " Die Zentralen Orte in Sqddeutschland ", which formulated much of what is now understood as central place theory.

Place theories look at crime at specific places, which can also be viewed as points on a map . ( Eck, Chainey, Cameron, and Wilson, 2005 : p . 10 ) Another crime theory used in regard to crime hotspots is neighborhood theories.

Experiments to distinguish between place theory and rate theory are difficult to devise, because of the strong correlation : large vibrations with low rate are produced at the apical end of the basilar membrane while large vibrations with high rate are produced at the basal end.

If a normal city distribution pattern is expected to follow the rank-size rule ( i . e . if the rank-size principle correlates with central place theory ), then it suggests that those countries or regions with distributions that do not follow the rule have experienced some conditions that have altered the normal distribution pattern.

Experiments to distinguish between place theory and rate theory using subjects with normal hearing are difficult to devise, because of the strong correlation between rate and place : large vibrations at a low rate are produced at the apical end of the basilar membrane while large vibrations at a high rate are produced at the basal end.
