Beginning with the understanding that a discipline's fundamental theories determine what questions researchers ask and what methods they use to answer them, scholars of criminology and criminal justice offer an overview of the value and use of a variety of methods and research techniques in those fields. In sections on general patterns and trends, special groups and problems, and crossing boundaries, they consider such topics as whether crime is rising or falling: a comparison of police-recorded crime and victimization surveys, innovative methods of gathering survey data on violence against women, methods of male sex work research: recommendations and future research opportunities, methodological challenges in collaborative research with immigrant women experiencing intimate partner violence in Canada, and agency records as a method for examining human trafficking.
