The Multi Nearest Neighbor Distance Method for Analyzing the Compound Effect of Infrastructural Elements on the Distribution of Activity Points

We propose a statistical method to analyze the compound effect of infrastructural elements (such as stations, arterial streets, and lakes) on the distribution of activity points (such as retail stores) over a region. First, we formulate a function that explicitly shows the compound effect of infrastructural elements. Second, we show an efficient computational method for estimating this compound function from data. Third, we develop multivariate statistical methods for testing several hypotheses about these compound effects. Last, we examine the compound effect of arterial streets and subway stations on the distribution of “high-class” apartment buildings in Sumida-Kohto, Tokyo.     

SIX SUMERIAN CUNEIFORM TEXTS IN JAPAN

The six cuneiform texts below are housed by two Japanese universities and recently attracted my attention. With the kind permissions of Prof. Koichi Yoshiike of the Faculty of Foreign Studies, the Aichi Prefectural University, and of Prof. Ryozo Matsumoto, Executive Director of the Tokai University Library, they are published.
