Host Ben Kieffer talks with Matt DeLisi, Associate Professor of Sociology and director of the criminal justice program at Iowa State University. De Lisi's new book is "Criminological Theory: A Life Course Approach". Delisi says career criminals aren’t necessarily born that way, but it’s a sequence of events and layering of risk factors over a lifetime that mold someone into a lifelong repeat offender. Later in the hour, a look at how global climate change affects violence. A new study co-authored by Iowa State Distinguished Professor of Psychology Craig Anderson shows that as the earth’s average temperature rises, so too does human "heat" in the form of violent tendencies.
