George Barker 1940-2018: A Tribute
David Goode,  Bath

Map and Explore: Hidden Hydrology
Jason King, Portland

Our cities are filled with hidden stories. Some of these tales are unlocked through conversations with long-time residents and oral histories, while others emerge through the written word, embedded in documents and biographies from the shapers and boosters that made our cities. Some hide in maps, a chronology of layers of changes over time, intimately spatial and tied to places,...

Enabling Efficient Urban Biodiversity Monitoring Through Modern Natural History and Citizen Science
Timothy Bonebrake, Hong Kong

The escalator that stretches from Victoria Harbour in central Hong Kong to the high-priced mid-levels neighborhood accommodates approximately 70,000 commuters daily. Surrounded by tall buildings, you would not at first glance expect to find much in the way of life other than never-ending humanity. However, even on this congested pathway on any given day you are likely to see red-whiskered...

Neural Networks—A New Model for “The Kind of Problem a City Is”
Mathieu Hélie, Montréal

Jane Jacobs’ final chapter of Death and Life of Great American Cities, titled “The Kind of Problem a City Is”, remains its most misunderstood. The principal ideas of the book have become the mainstream of urban know-how and helped the triumphant turnarounds in the fortunes of American cities, most notably for New York City. But the last idea in the...

A projection screen stood on the baggage carousel, and former glass-walled airport offices held bulletin boards and tables of sticky notes for brainstorming sessions. Exhibition boards in...

Urban schools—any public, private, or charter schools delivering formal primary or secondary education—are key institutions in the shaping of vibrant and sustainable cities. Imagining such cities depends on the assumptions and ideologies of those involved in the transformation of urban sites, and moving beyond perceiving urban schools as problematic institutions (Pink and Noblit, 2007). Globally, a steady process of urbanization...
