Additional publications may be listed for review on a monthly or quarterly basis by visiting the Choose a current topic: Develop a hypothesis for a research area about which articles are continuing to be published. Understanding these effects is important in understanding the very nature and desirability of Independent Variable (IV) - the variable manipulated (changed) by the researcher to determine if it will lead to change in the dependent variable (s) - in some studies, this is easily identified as the grouping variable. better ensure that their services to, and advocacy for, victims of crime will be of high quality.
