David Yokum Goldstone Forum: Tales of Psychological Science from City Hall to Oval Office Claudia Cohen Hall, Terrace Room, 249 South 36th Street

There is currently a unique attempt, emerging from within government itself, to integrate the insights and experimental methods from the psychological sciences directly into day-to-day governance. David Yokum, a founding fellow of President Obama’s Social and Behavioral Sciences Team, will talk about the latest work emerging from the front lines, most notably a new initiative, The Lab @ DC, from the District of Columbia Government. As part of exploring the unique roles that social scientists can play in experiment-based policy-making, he’ll touch on examples ranging from a randomized controlled trial of police body-worn cameras to a “form-a-palooza” that aims to systematically improve every government form based on psychological insights. He will also describe a novel effort underway to integrate open science principles and political process.

Rita Barnard Learning from Mandela 3401 Walnut Street, Center for Africana Studies

Nelson Mandela is one of the most revered figures of our time.  A "life-loving man” by his own description, he committed himself to a compelling political struggle, faced the death penalty, and endured a prison sentence that entailed the sacrifice of a third of his life to his cause. During these long years, he became the world’s best-known prisoner, a symbol of his own people’s demand for liberation, and a galvanizing icon for millions of all around the world who yearned for a politics of moral conviction. Mandela was never uncontroversial: some have labelled him a sell-out, others a terrorist. But the qualities of leadership he displayed are inspiring to remember in our dark times.

The Center for Africana Studies presents this brief screening and a talk on the life and legacy of humanitarian and freedom fighter, Nelson Mandela. Professor Barnard will discuss Mandela’s style and character—a leader of dignity, courage, consistency, flexibility, and magnanimity.

Nancy Steinhardt How Chinese Architecture Became Modern, 1927-1977Penn Lightbulb Cafe World Cafe Live, 3025 Walnut Street

From 1927, when the first group of Chinese architects trained abroad returned home, to 1977, the year Mao Zedong died, Chinese architecture transformed from buildings like the Forbidden City to a modern building system inspired by Western architecture. France, the United States, the Soviet Union, Taiwan, and Japan are all part of this story that takes place during the war-torn 1930s and 1940s, through the Soviet advisors of the 1950s and the Cultural Revolution of 1966-1976. Sun Yat-sen and Mao were central to China’s drive toward modernism in this tumultuous half-century.

Expert faculty from the University of Pennsylvania shed light on their research in the arts, humanities, and social sciences at the Penn Lightbulb Cafe. It's an evening of engaging, stimulating conversation, with a Q&A session following each talk.
