Survey of Occupy Movement Participants

In February 2012, Professor Maguire and some of his doctoral students and colleagues from other universities designed this instrument to measure perceptions of law and justice among members of the Occupy movement.  As of April 2012, the survey had been fielded primarily in Washington DC and New York City, with small-scale data collection also taking place in Charlotte, Houston, Dallas, Oakland, and Phoenix.

Other universities involved in this project include Arizona State University, Sam Houston State University, San Francisco State University, and the University of California at Berkeley.

Measuring Police Service Quality in Orangetown

Professor Maguire and his honors students worked with officers from a police agency to develop this citizen survey instrument.  The goal was to measure the dimensions of perceived service quality of police outlined in a Police Foundation report entitled Policing for People (written by Stephen Mastrofski).  The police agency requested anonymity, so it was assigned the pseudonym "Orangetown."
