1. In a book titled Geography of Time (1997), Robert Levine operationalized the pace of life in cities around the world with a composite measure of the following: a. How long it took a single pedestrian to walk 60 feet on an uncrowded sidewalk. b. What percentage of public clocks displayed the correct time. C. How long it took to purchase the equivalent of a first-class postage stamp with the equivalent of a $5 bill. Discuss possible reliability and validity issues with these indicators of pace of life. Be sure to specify a conceptual definition for "pace of life."
