For hot meals, he advises that the container be filled up with boiling water first to kill any bacterias.The researchers then created a computer model with that information to predict who would go on to commit serious violent crimes. The investigators discovered that the 5 % of soldiers informed they have the highest predicted risk accounted for 36 % of most major physical violent crimes dedicated by men, and 33 % of the crimes committed by women during the six-year study. The study findings were published online Oct. 6 in Psychological Medicine. The study was funded by the U.S. Department of Defense. The experts also tested the model on a far more recent band of Army personnel. The scholarly study period for this group was from 2011 to 2013. The 5 % of soldiers with the model’s predicted highest risk accounted for 50 % of all major physical violent crimes, the study showed. ‘These numbers are striking,’ the study’s principal investigator, Ronald Kessler, a professor of healthcare plan at Harvard Medical College, said in the news release.
