Spatial Point Pattern Analysis and Industry Concentration
Traditional measures of spatial industry concentration are restricted to given areal units. They do not make allowance for the fact that concentration may be differently pronounced at various geographical levels. Methods of spatial point pattern analysis allow to measure industry concentration at a continuum of spatial scales. While common distancebased methods are well applicable for sub-natio...
متن کاملSpatial point pattern analysis of prehospital naloxone administrations
Objectives The increasing problem in the United States with opioid dependence and overdose, often fatal, is well-recognized. As naloxone has only one clinical use— the treatment of opioid overdose—its administration by EMS personnel can serve as a surveillance indicator for opioid overdose. This study uses specific locations of EMS calls, and methods of point pattern analysis, to detect overall...

Page 146ff. Section 3.1.2.1 Different Strategies for Deriving Edge Correction Weights Both, “Stoyan edge correction” and “Ohser edge correction” were published by Ohser and Stoyan (1981). The Stoyan edge correction is also called “translation edge correction”, and the “Ripley edge correction” is also called “Isotropic edge correction”. An early summary of edge correction methods is given in Rip...

متن کاملSpatial and temporal distribution of fishing resources exploited by the Manaus fishing fleet, Amazonas, Brazil.
Fishing resources are important generators of income and food for the rural and urban people in the Amazon. The present paper investigates fishing and environmental variables determining fishing production landed in Manaus and evaluates the relative abundance of commercial fishes in the different sub-systems of the Central Amazon basin. Information collected was used to test the new catch index...
