Accessibility has become a key issue in modern urban planning. This paper aims to identify the impact of differences in spatial accessibility on the development of the built environment in cities. Using a few simple accessibility indicators, it tries to map out in a quantitative way the detailed implications of accessibility conditions for built-up areas, on the basis of a 25x25m grid cell appr...

In response to the fragmentation of individuals brought on by globalization, it is important to expand the positioning of the four quadrants of public space, based on cosmopolitanism, in order to re-establish the creativity of cities. By examining cases such as that of cultural urban branding at BMW-MINI, and Montreal’s puppet theatre, which chose to adopt the methods of Bunraku for its display...

Objective: To estimate the cost-effectiveness of intravenous linezolid as a first-line agent against intravenous vancomycin in treating methicillin-resistant Staphylococcus aureus–confirmed nosocomial pneumonia in four Chinese cities. Methods: A decision-analytic model of 4-week time horizon was used to conduct costeffectiveness analyses from the payer’s perspective. Clinical outcomes and resou...

Untreated sewage samples from 12 cities in the United States were screened for the presence of recently characterized RNA and DNA viruses found at high prevalence in the stool specimens of South Asian children. Genetic variants of human cosaviruses and cardioviruses in the Picornaviridae family and of DNA circoviruses and human bocaviruses were detected, expanding the known genetic diversity an...

A hybrid life cycle-based trans-boundary greenhouse gas (GHG) emissions footprint is elucidated at the city-scale and evaluated for 8 US cities. The method incorporates end-uses of energy within city boundaries, plus cross-boundary demand for airline/freight transport and embodied energy of four key urban materials [food, water, energy (fuels), and shelter (cement)], essential for life in all c...

We employ Quah’s [13] transitional matrix and Rey’s [16] Spatial Clustering Index (SCI) to analyze the dynamics in Chinese city income distribution both from temporal and spatial dimensions. Our empirical results show that cities in eastern China enjoy more favorable movements in income distribution during urban post-reform era compared with her western and central counterparts; the dynamic spa...

This paper presents a theoretical framework for the analysis of business models that involve public actors, and city governments in particular, in the value network. It starts from an established business model framework and expands it to include an additional set of parameters required to successfully perform a qualitative analysis of the business models of new (digital) services offered by ci...

This paper analyzes urban growth boundary delimitation in the urban master plan in Shaanxi Province and chooses Baoji, Weinan and Ankang as the research object. The three cities have delimited urban growth boundaries. This paper compares interrelationships between urban spatial structure, urban size, delimitation of the four areas, boundaries of planning area, natural boundaries, artificial bou...

In this paper we examine the information sharing practices of people living in cities amid armed conflict. We describe the volume and frequency of microblogging activity on Twitter from four cities afflicted by the Mexican Drug War, showing how citizens use social media to alert one another and to comment on the violence that plagues their communities. We then investigate the emergence of civic...
