A countdown clock sits on Hartford Mayor Arunan Arulampalam’s desk in City Hall, showing the number of days left in his term (1,150 on the day Harvard Public Health visits). It’s a memento from a Harvard Business School program for new mayors he’s participating in. Arulampalam jokes that he had a harder time in the program than the other new mayors because Hartford was the case study on a failure to collaborate. The events of the case happened 25 years ago, but “I’m still getting shit for it” from the other mayors, he says.
