New immigrants are changing America’s cities in many ways, but what is happening in immigrant neighborhoods is not always easily understood. Sandra Ball-Rokeach and Vikki Katz, both at the Annenberg School for Communication at the University of Southern California, are working in the immigrant neighborhoods of Los Angeles to learn how communication flows and what that means to mainstream media and political leaders. Vikki is a Ph.D. student at the Annenberg School. Sandra is the director of the Communication Technology and Community Program there and director of the Metamorphosis Project.

Todd Hoffman, president of Collegia, is also with us this week. Collegia works with colleges and communities to attract and retain top student talent.
