In this paper, built-up land expansion patterns and the associated factors were characterized in urban and non-urban areas across the Wen-Tai region of eastern China. Fractal dimension can be used as a reliable indicator of the complexity of built-up land form, and the increasing trend of fractal dimension indicated a more complex, dispersed pattern of built-up land in urban areas. Spatial regr...

Urban system is a dynamic complicated system involved with many uncertainties, thus always leading to an undesired situation that the city doesn't develop as the previously made urban plans. Urban planning implementation evaluation, which is devoted to urban planning implementation supervision and management, is an important and indispensible part of efficient, healthy and sustainable urban dev...

Facing urban warming, mitigation and adaptation strategies are not efficient enough to tackle excessive urban heat, especially at the local scale. The local climate zone (LCZ) classification scheme is employed to examine the diversity and complexity of the climate response within a city. This study suggests that zonal practice could be an efficient way to bridge the knowledge gap between climat...

A quantitative understanding of complex urban growth patterns and processes is crucial to sustainable land management and urban development planning in cities. The spatial organization of urban patterns can be treated as fractals and can be characterized with fractal dimension. However, the calculation of fractal dimension of urban form is often constrained by imperfect and incomplete higher te...

With the increasing use and complexity of urban natural gas pipelines, the occurrence of accidents owing to leakage, fire, explosion, etc. has increased. To analyze the scope of impacts of single-point fires associated with urban natural gas pipelines and the spread of urban fires caused thereby, this study analyzes single-point fires and the dynamic spread of fires by using a natural gas pipel...

have already developed an array of more refined tools to quantify the integrated social and biophysical structure within urban mosaics [10], and to better understand the subtle roles of urban social processes and recognize new modes of social differentiation [11]. We also believe that coarse-scale aggregated measures have an even more critical role to play in urban ecological studies owing to t...

Rapid urbanization has made the inner city change quickly with the urban sprawl of the whole city. In China, a mass of urban renewal projects have been carried out for meeting the new need of people’s life. However, the traditional means of total renewal has destroyed the urban heritage seriously, which especially led to the diminishing of historical district space. It is urgent to protect and ...

Purpose Urban consolidation centres (UCCs) are often conceived to improve services in retail stores and potentially reduce costs. However, few studies have examined how retail stores perceive the services a UCC could provide. The purpose of this article is to explore retail stores’ potential demands for different services that a UCC could provide in order to foster the development and implement...

Social workers delivering services in health care settings face unique challenges and opportunities. The purpose of this study was to solicit input from social workers employed in urban hospitals about their perceptions of the roles, contribution, and professional functioning of social work in a rapidly changing health care environment. Using qualitative methods, the university and hospital-bas...

Let p be a fixed prime number. Throughout this paper Zp, Qp, and Cp will, respectively, denote the ring of p-adic rational integers, the field of p-adic rational numbers, and the completion of algebraic closure of Qp. For x ∈ Cp, we use the notation x q 1 − q / 1 − q . Let UD Zp be the space of uniformly differentiable functions on Zp, and let vp be the normalized exponential valuation of Cp wi...
