A study following teens who had summer jobs (暑期工)found violent crime(暴力犯罪) in that population almost cut in half, during and following the employment.
Violence is more than a criminal problem. It’s also a public health issue. More than 6,000 people are injured annually (每年)due to violence, mostly young people in low-income neighborhoods(社区). Jobs programs for teens done with school have proven costly and seem to do little to reduce violence. But summer employment for kids still in school may be effective(有效的), according to a study by criminologist (犯罪学者)Sara Heller at the University of Pennsylvania.
She followed more than 1,600 young people, many of whom took part in a Chicago program called One Summer Plus. It offers 8-week stints at jobs such as camp counselors(营队辅导员), community gardeners(园艺大师), or government office workers at minimum wage.
One group of kids worked 25 hours a week, with an adult mentor(指导者). Another group worked 15 hours and got 10 hours of social-emotional education(情感教育). A control group got nothing. Based on school and police records, Heller found a 43 percent decrease in violent crime in the two groups that had jobs. This lasted long after the program ended.
The work apparently helps students learn to manage conflict, reduce frustration(挫败) and improve self control. Heller concludes that intervention(介入) programs can be low-cost and effective, “even for a problem as destructive(破坏的) and complex as youth violence.”
