More than 6,000 people       (injure) annually due to violence, mostly young people in low-income neighborhoods .Job programs for teens done with school have proven        ( cost) and seem to do little    ( reduce) violence.
But summer employment for kids still in school may be effective, according to a study by criminologist Sara Heller at the University of Pennsylvania.
She followed more than 1,600 young people, many of     took part in a Chicago program called One Summer Plus. It offers 8-week stints at jobs such as camp counselors, community gardeners, or government office workers at minimum wage.
One group of kids worked 25 hours a week, with an adult mentor. Another group worked 15 hours and got 10 hours of social-emotional    ( educate).
A control group got nothing.      ( base)on school and police records, Heller found a 43 percent decrease in __  ( violence) crime in the two groups that had jobs. This lasted long after the program ended.
The work    ( apparent)helps students learn to manage conflict, reduce frustration   improve self -control.
Heller concludes that intervention programs can be low-cost and effective, “even for     problem as destructive and complex as youth violence.”
