Back on My Feet, the Philadelphia-based nonprofit that helps the city's homeless population by promoting running and encouraging self-sufficiency, marks its third anniversary this month and will soon announce its 2011 expansion plans. Jeremy Jordan, an assistant professor at Temple's School of Tourism and Hospitality Management, and his students have spent the past year studying the organization and have found that the more connected participants are to the program, the more positive changes occur in other areas of their lives. "It's definitely working," Jordan said. "When you think of this population, one of the challenges is keeping them engaged in any type of program that is longitudinal in nature."
