Cities are characterized by concentrating population, economic activity and services. However, not all cities are equal and a natural hierarchy at local, regional or global scales spontaneously emerges. In this work, we introduce a method to quantify city influence using geolocated tweets to characterize human mobility. Rome and Paris appear consistently as the cities attracting most diverse vi...

Global economic restructuring and technological change are transforming the map of global production and the global division of labor. Based on the perspectives of global value chains and global production networks, this study analyzes the production networks, value chains, and spatial organization of the computer industry in China. It was found that the notion of a symmetric, bell-shaped smili...

China was responsible for 25 per cent of global carbon dioxide emissions in 2012 (Liu 2015). This followed the passing of key milestones in the previous decade. From 2007, China’s per capita carbon dioxide emissions exceeded the world average and it has become the world’s largest contributor to annual carbon dioxide emissions, with the burning of fossil fuels and cement production being two imp...

In this paper we examine house price synchronization in 15 global cities using real data from 1995:Q1-2020:Q2. We find that although there is evidence for bilateral positive phase synchronization, no an integrated housing market our sample of cities. Using a hierarchical clustering approach, identify three clusters with similar cycles are not solely determined by geographic proximity. interpret...

Globally, many built environments fail to meet the accessibility needs of people with disability. This is despite disability agitating for environment improvement decades. paper critically reviews global literature determine what constitutes an accessible and inclusive city discover benchmarks cities. We identified five (composite) domains that would include: 1.Connectivity (spatial & digit...

To determine why North Americans tend to locate European cities south of North American cities at similar latitudes (Tversky, 1981), we had observers provide bearing estimates between cities in the U.S. and Europe. Earlier research using latitude estimates of these cities has indicated that each continent has several subjective regions (Friedman & Brown, 2000a). Participants judged cities from ...
