Flooding in urban areas is an inevitable problem for many cities in Asia. In Bangladesh, Dhaka has serious problems related to urban flooding. The situation was highlighted in September 1996 when residences experienced ankle to kneedeep water on the streets. Daily activities in parts of the city were nearly paralyzed and heavy traffic jams occurred due to stagnant water on the streets. The stud...

This article examines three contemporary Australian poems that concern themselves with matters of the sacred within the modern Australian city. Noting that Australian poetry and the sacred have often been studied in terms of the landscape, the article approaches these poems as part of an undercurrent of spiritual or sacred writing that takes up urban Australian spaces as important and resonant ...

We consider a single intersection of two two-way streets with controllable traffic lights on each corner. We construct a model that describes the evolution of the queue lengths in each lane as a function of time, and we discuss how (sub)optimal traffic light switching schemes for this system can be determined.

We introduce the concept of “asymmetrical adaptability.” Using 66 teams, we replicated the common cross-sectional structural contingency finding that functional structures perform better within predictable environments, whereas divisional structures performed better within unpredictable environments. Unlike most tests of contingency theories, however, we directly tested whether teams could actu...

Transportation-related skills have been identljied by parents as a critical area in which to teach children and youth to be more independent [I]. Crossing Streets, our initial effort to investigate skill acquisition and generalization in a virtual reality environment, will attempt to teach children, including those with disabilities, a safe way to cross a street.

BACKGROUND Regular physical activity can help prevent chronic diseases, yet only half of US adults meet national physical activity guidelines. One barrier to physical activity is a lack of safe places to be active, such as bike paths and sidewalks. Complete Streets, streets designed to enable safe access for all users, can help provide safe places for activity. COMMUNITY CONTEXT This communit...

Background: Ciclovias, known in the U.S. as open streets initiatives, close streets to vehicles to increase open space and physical activity opportunities for local communities. In San Francisco, California, the open streets initiative known as Sunday Streets, was founded in 2008 to promote bicycle use in neighborhoods most underserved for recreational resources and experiencing higher than ave...
