As Chicago Ideas Week events continue throughout the city, Eight Forty-Eight invites listeners to call, e-mail and tweet their big ideas for Chicago. Robert Wolcott, executive director of the Kellogg Innovation Network, helps the show spot the good and bad.

And Changing Gears’ Niala Boodhoo travels to Ohio to find out how science can help bridge the gap between an idea and an actual product available for sale. Then, WBEZ’s Natalie Moore and Gabriel Spitzer examine the state and effectiveness of the Chicago-area’s current trauma care system. In preview of the new series, Out of the Shadows, the show meets 18-year-old Shakena, who struggles with the stigma of mental illness. Then, Evelyn DeHais from the Occupy Chicago movement joins Eight Forty-Eight to talk about the movement’s goals; and In These Times’ Joe Macare joins the conversation to help compare the Occupy movements to other protests.
