Pocket Calculator in Papua New Guinea; Chicago

The Great American City - US Professor of Social Sciences, Robert J Sampson, discusses his landmark research project with Laurie Taylor. Following in the influential tradition of the Chicago School of urban studies, but updating it for the twenty-first century, he argues that communities do still matter because life is decisively shaped by where we live. Neighbourhoods influences a wide variety of phenomena including teen births, altruism and crime. Not even national crisis can destroy the enduring impact of place.

Also, the anthropologist, Anthony Pickles, reveals the significance of pockets for controlling money in Highland Papua New Guinea.
