The process of finding historical articles which document the empirical relationship between immigration and crime has been particularly fascinating. The assertion that immigrants exhibit higher rates of delinquency than their native born counterparts has been posited in numerous articles since the beginning of the 20th century.

Analysis of Dissolved Organic Matter in Agricultural Runoff

Dissolved organic matter (DOM) is the variety of molecules composed primarily of carbon, hydrogen in surface waters and groundwater that are typically leached from plants and soils. This mobile group of molecules plays a key role in biogeochemical processes, ecological processes, and the global carbon cycle. The composition of this organic matter can vary greatly depending on its original source and the degree to which it is broken down by microbial activity.
