There is much enthusiasm currently about the possibilities created by new and more extensive sources of data to better understand and manage cities. Here, I explore how big data can be useful in urban planning by formalizing the planning process as a general computational problem. I show that, under general conditions, new sources of data coordinated with urban policy can be applied following f...

Healthy people live in healthy communities. Nowhere is that more apparent or more challenging than in cities. Cities face unique challenges with regard to changes in their economic base, concentrated poverty, housing quality and affordability, violence, and pollution exposure. Health outcomes closely track with these challenges. The health of cities is often expressed in aggregate measures of t...

Big data plays an important role in smart city. Big data analytics is one of the recent technologies that could enhance smart city services. It provides valuable insights from massive volume of data collected through various sources. The combination of big data and Internet of Things (IoT) supports urban decision makers and provides better services to the citizens. This paper is focused on revi...

Urban heat island is among the most evident aspects of human impacts on the earth system. Here we assess the diurnal and seasonal variation of surface urban heat island intensity (SUHII) defined as the surface temperature difference between urban area and suburban area measured from the MODIS. Differences in SUHII are analyzed across 419 global big cities, and we assess several potential biophy...

the space structure that governs cities has depended on several corresponding relations and various factors which consist of: population, job and activities, transportation patterns, urban sub-structures, various services and etc that always were connected to each other and have formed its space structure. but since these relations are more complicated in big cities, the importance of paying at...

This study examines how human capital externalities affect audit markets in U.S. cities. A high level of human capital is predicted to improve the quality of labor in all audit firms, but a stronger effect is expected for the more “locally tied” non-Big 4 audit offices. Consistent with this, the quality of audited earnings improves as human capital increases, but the relation is stronger for no...

A LONG-STANDING BELIEF in development studies holds that, on the whole, living conditions in developing countries are superior for residents of large cities than for persons living in smaller cities, towns, and villages. The concept of big cities as " islands of privilege " (Harrison 1982: 145) is fundamental to otherwise discrepant theories of modernization, dependency, world systems of cities...
