Global analysis of functional patterns of individual cities in scientific collaboration networks
How Distance Decay Effects Shape Accessibility of Food Provided by Online Food Delivery Services: Evidence from Two Chinese Megacities
Ensuring adequate access to healthy food is essential for public health. As a rapidly growing food access channel, online food delivery (OFD) services have gained widespread popularity globally, particularly in China. The accessibility of food through OFD retailers remains underexplored, however. This study addresses this gap by analyzing comprehensive data sets of 129,140 OFD retailers and 240,455 offline food retailers across ten categories in …
Exploring the relationship between land use change patterns and variation in environmental factors within urban agglomeration
How Retailer Hierarchy Shapes Food Accessibility: A Case Study Using Machine Learning Method to Delineate Service Areas and Hierarchical Levels of Food Retailers
Accurate evaluation of food accessibility is the prerequisite for developing sustainable food policies. Most existing studies have evaluated food accessibility by setting a single service area size for all food retailers across a study area. In reality, service area sizes can vary significantly among different types of food retailers in different geographical regions, thus forming a retailer hierarchy. In this study, we propose a new machine lear…
Efficient Algorithm for Constructing Order K Voronoi Diagrams in Road Networks
The order k Voronoi diagram (OkVD) is an effective geometric construction to partition the geographical space into a set of Voronoi regions such that all locations within a Voronoi region share the same k nearest points of interest (POIs). Despite the broad applications of OkVD in various geographical analysis, few efficient algorithms have been proposed to construct OkVD in real road networks. This study proposes a novel algorithm consisting of …

Delineating a hierarchical organization of ranked urban clusters using a spatial interaction network
The rank boost by inconsistency in university rankings: Evidence from 14 rankings of Chinese universities
University ranking has become an important indicator for prospective students, job recruiters, and government administrators. The fact that a university rarely has the same position in different rankings motivates us to ask: To what extent could a university’s best rank deviate from its “true” position? Here we focus on 14 rankings of Chinese universities. We find that a university’s rank in different rankings is not consistent. However, the rela…
The dominance of big teams in China’s scientific output
Modern science is dominated by scientific productions from teams. A recent finding shows that teams of both large and small sizes are essential in research, prompting us to analyze the extent to which a country’s scientific work is carried out by big or small teams. Here, using over 26 million publications from Web of Science, we find that China’s research output is more dominated by big teams than the rest of the world, which is particularly the…
The sense of community revisited in Hankow, China: Combining the impacts of perceptual factors and built environment attributes
Rethinking place-making: Aligning placeness factors with perceived urban design qualities (Pudqs) to improve the built environment in historical districts
Associating Covid-19 Severity with Urban Factors: A Case Study of Wuhan
Wuhan encountered a serious attack in the first round of the coronavirus disease 2019 (COVID-19) pandemic, which has resulted in a public health social impact, including public mental health. Based on the Weibo help data, we inferred the spatial distribution pattern of the epidemic situation and its impacts. Seven urban factors, i.e., urban growth, general hospital, commercial facilities, subway station, land-use mixture, aging ratio, and road de…

Scaling of Geographic Space as a Universal Rule for Map Generalization
Map generalization is a process of producing maps at different levels of detail by retaining essential properties of the underlying geographic space. In this article, we explore how the map generalization process can be guided by the underlying scaling of geographic space. The scaling of geographic space refers to the fact that in a geographic space, small things are far more common than large ones. In the corresponding rank-size distribution, th…
Zipf's law for all the natural cities in the United States: A geospatial perspective
This article provides a new geospatial perspective on whether or not Zipf's law holds for all cities or for the largest cities in the United States using a massive dataset and its computing. A major problem around this issue is how to define cities or city boundaries. Most of the investigations of Zipf's law rely on the demarcations of cities imposed by census data, for example, metropolitan areas and census-designated places. These demarcations …
