"Just the Maths"
Developed by a retired mathematics professor from Coventry University, this website "is a collection of separate units, in chronological topic-order, intended to service foundation level and first year degree level courses in higher education, especially those delivered in a modular style." Although there are separate sections for students and teachers, both contain essentially the same information except for the format of the material -- printable pages with slightly more detailed explanations
Using Geographic Information Systems to Map Crime Victim Services
The US Department of Justice released this document in February 2003 about the use of geographic information systems (GIS) in law enforcement. "GIS is an application that links database software to graphics software to create visual images of various types of data in map format." The report outlines the applications of such systems in police cars and at victim assistance facilities, providing examples of situations where it has been used successfully and cases that could have benefited from GIS.
