Port cities in the global age; from Marseilles to Liverpool and New Orleans. Laurie Taylor talks to Alice Mah, a sociologist at the University of Warwick, about her study of transformation along city waterfronts. What happens when world harbours are relegated to minor seaports? Can they ever return to their former greatness? Also, middle class alcohol use often exceeds safe levels but little research explains why. Lyn Brierley-Jones, a Research Fellow at the University of Sunderland, explores the meaning of drinking amongst professional workers.
