Germany's big cities are gaining in attractiveness both as a place for living and as a location for companies. Even as Germany's total population is declining, the population of cities increased by nearly 3 percent between 1999 and 2008. The same is true for spatial shifts in the economy: During the past 10 years employment in big cities increased by nearly 4 percent while stagnating in Germany...

one of the methods of preventing crimes is ‘situational prevention’ that is to design environment, change physical conditions and with controlling of environment and crime opportunities decreases the rate of crime in the society. some of these ways concentrates on environmental changes, control of criminals and supporting weak victims and taking care of crime targets. since development of civil...

One of the main reasons of unsustainability of city development in Iran is that planners and mayors have not almost been able to create connections between different dimensions of a city. Sustainability indicators are evaluation tools of cities operation applicable in living environmental, economical, and social aspects. The purpose of this paper is to offer a framework including the descriptio...

We propose a new polynomial-time deterministic algorithm that produces an approximated solution for the traveling salesperson problem. The proposed algorithm ranks cities based on their priorities calculated using a power function of means and standard deviations of their distances from other cities and then connects the cities to their neighbors in the order of their priorities. When connectin...

Urban futures that are more resilient and sustainable require an integrated social-ecological system approach to urban policymaking, planning, management, and governance. In this article, we introduce the Urban Biodiversity and Ecosystem Services (URBES) and the Cities and Biodiversity Outlook (CBO) Projects as new social-ecological contributions to research and practice on emerging urban resil...

The literature on urban development politics provides clues, but no consensus, regarding the orientation of local governments toward specific types of new growth. This paper examines the receptivity of cities to industrial, commercial, and residential development, drawing upon a mail survey of top administrative officials in 330 California municipalities. Bivariate data suggest that communities...

Resource-based cities face unique challenges when undergoing urban transitions because their non-renewable resources will eventually be exhausted. In this article, we introduce a new method of evaluating the urban transition performance of resource-based cities from economic, social and eco-environmental perspectives. A total of 19 resource-based cities in Northeast China are studied from 2003 ...

Geographical location and landforms of various types have strong effects on the developments of many cities and associated street networks. This study presents new results of landform effects, in particular the geometry of shorelines, on the grid street networks (a total of 10,442 streets) of three Brazilian coastal cities. The results are compared with the street networks of three coastal citi...
