Physical disorder is associated with negative outcomes in economic performance, public health, and social stability, such as the depreciation of property, mental stress, fear, and crime. A limited but growing body of literature considers physical disorder in urban space, especially the topic of identifying physical disorder at a fine scale. There is currently no effective and replicable way of measuring physical disorder at a fine scale for a lar…
China's Changing Regional Disparities during the Reform Period
I examine regional disparities in China during the reform period (1978-94) based on the latest measures of provincial per capita GDP. Results reveal a "U-shaped" pattern in regional inequality over time. Regional inequality in per capita GDP among the 30 provinces of China diminished as reforms progressed until 1990, after which it started widening. This diminishing trend was due to a significant decline in income inequality among provinces in th…

Losers and Pareto optimality in optimising commuting patterns
When optimising the overall commuting pattern for a city or a region, there are often winners and losers among commuters at the subdivision level. Losers are those who are burdened with longer commutes than before the optimisation. Knowing who or where losers are is of interest to both researchers and policy-makers. The information would help them efficiently locate losers and compensate them. Few, however, pay attention to such losers. By revisi…
Outside the ivory tower: Visualizing University Students’ Top Transit-Trip Destinations and Popular Corridors
Universities are where innovations, face-to-face interactions and social capital are commonplace. Nevertheless, often regarded as ‘the ivory tower’, universities cannot be separated from the social and economic transformations outside of them. Traffic, information and financial flows between universities and other locations can be used to reveal connections between the ivory tower and other locales. Therefore, this paper uses the weekday public t…
