This article explores the ways in which communications technologies influence the shape and form of cities and large metropolitan regions. After reviewing the scholarly literature, the author suggests that there is a need to consider the ways in which telecommunications can lead to both the centralization and decentralization of economic activity. The article analyzes the limits and opportuniti...

We solve the special case of the Euclidean Traveling Salesman Problem where II m cities lie on the boundary of the convex hull of all n cities, and the other m cities lie on a line segment inside this convex hull by an algorithm which needs O(mn) time and O(n) space.

space, according to Brian IL. Berry's famous expression (1964) «cities as Systems within a System of cities». Thus, the focus on the dynamic study of the general characteristics of the object «town» in an urban system of dissymetric interdependencies at a regional, national or global scale (Pumain 1997) was followed by the study of cities as physiognomic and socio-economic entities.This is diff...

This paper presents a descriptive analysis of wage inequality in Colombia by cities and industries and attempts to evaluate the impact of the inequality of industries on inequality of cities. Using the 2104 Colombian Social Security data, we calculate the gini coefficient for cities and industries and draw comparisons between their distributions. Our results show that while cities are unequal i...

In the simple version of the model presented in “Urban Structure and Growth”, we made assumptions designed to ensure that cities would perfectly specialize in terms of the industries producing in them. This assumption was for the purposes of simplicity, but also served to capture the idea that there are substantial di¤erences in the industry composition across cities. Nevertheless, cities are n...

Using data on all scientific publications from the Scopus database, we find a superlinear scaling effect for U.S. metropolitan areas as indicated by the increase of per capita publication output with city size. We also find that the variance of residuals is much higher for mid-sized cities (100,000 to 500,000 inhabitants) compared to larger cities. The latter result is indicative of the critica...

This article describes a new model for urban planning in ancient and preindustrial cities that moves beyond the traditional simplistic dichotomy of planned versus organic cities. The model has two components: coordination of buildings and spaces, and standardization among cities. A variety of coordinated arrangements of buildings reflect urban planning, including simple coordination, formality ...
