Two of the most provocative sessions at the 2008 Encore Careers Summit, "Lessons for a New Social Movement" and "Journeying Through Multiple Careers," are now available podcasts as part of Stanford's series of Social Innovation Conversations

In "Lessons for a New Social Movement," four distinguished panelists discuss the origins of three great social movements in the United States: the women's movement, the civil rights movement and the environmental movement and explore the lessons for the encore careers movement as it seeks to harness the energy of people over age 50 to tackle urgent social challenges.

The panelists are: Peter Osnos, founder and editor-at-large of Public Affairs, an independent publishing company; Clayborne Carson, professor of history and founding director of the Martin Luther King Jr. Research and Education Institute at Stanford University; Denis Hayes, president of the Bullitt Foundation and the immediate past chair of the Energy Foundation; and Suzanne Braun Levine, a nationally recognized authority on women, media matters and family issues who was the founding editor of Ms. magazine and editor-in-chief of the Columbia Journalism Review.

In "Journeying Through Multiple Careers," five panelists talk about the unexpected paths that lead people to encore careers, as well as their hopes that government will support people in moving through multiple professions.

The panelists are Marci Alboher, a freelance columnist and blogger who wrote One Person/Multiple Careers: A New Model for Work/Life Success; Conchy Bretos, CEO of MIA Consulting Group, a for-profit corporation that creates public housing and affordable assisted living facilities; W. Wilson Goode Sr., a former mayor of Philadelphia who now serves as director and organizer of Amachi, a national mentoring program for children of incarcerated parents; Anthony Radocaj, a site leader for Experience Corps in Philadelphia; and Beverly Ryder, an experienced banking and energy executive who currently helps the Los Angeles Unified School District build business partnerships.
