Intelligent simulation of urban vacant land
Scientific redevelopment of urban vacant land is crucial for improving land use efficiency and enhancing the quality of human settlements. However, existing approaches often struggle to reconcile city-wide coordination with parcel-level adaptability, and tend to emphasize individual objectives at the expense of broader economic, social, and environmental outcomes. These limitations constrain their ability to support flexible and coordinated mixed…
Decoding urban park use patterns from a day–night disparity perspective
Urban parks are recognized as important public spaces that support the health and well-being of urban residents. Although georeferenced data have been widely applied in park evaluations, most existing studies address temporal variation by analyzing different time periods separately, rather than adopting a comparative perspective to identify distinct park typologies. This study utilized large-scale mobile phone data from Nanjing, China, to investi…
Intelligent mapping of urban scenic view corridors based on public perception
The rapid urbanization process has increased the need to protect the scenic view corridors associated with iconic urban landscapes. However, existing approaches primarily rely on static viewshed analysis and expert judgement, which are limited to capture dynamic public movement and perception preferences. Therefore, this study proposes an intelligent framework that uses multi-source data, a random walk model, and a random forest algorithm to iden…
Toward interpretable urban spatial layout generation
Contrastive Learning with Image Deformation and Refined NT-Xent Loss for Urban Morphology Discovery
The traditional paradigm for studying urban morphology involves the interpretation of Nolli maps, using methods such as morphometrics and visual neural networks. Previous studies on urban morphology discovery have always been based on raster analysis and have been limited to the central city area. Raster analysis can lead to fragmented forms, and focusing only on the central city area ignores many representative urban forms in the suburbs and tow…
Revealing disparities and driving factors in leisure activity segregation of residents and tourists
Activity-based segregation can lead to inequalities and exclusivity, hindering the inclusive construction of sustainable cities. However, few studies have delved into leisure segregation among residents and tourists across their full leisure activities. To address this gap, this paper examines Zhoushan, an island tourist city in China, aiming to quantify the leisure segregation of residents and tourists in the whole city, and to analyze the drivi…

Objective: The purpose of this study is to provide experience and evidence support for countries to deal with similar public health emergencies such as COVID-19 by comparing and analyzing the measures taken by six countries in epidemic prevention and control. Methods: This study extracted public data on COVID-19 from the official website of various countries and used ecological comparative research methods to compare the specific situation of ind…
Disparities and effectiveness of Covid-19 vaccine policies in three representative European countries
Expanding vaccination coverage has played a positive role in reducing COVID-19 infection and mortality rates and stabilizing Rt. Priority vaccination strategies targeting older people and at-risk groups have been shown to be effective in reducing COVID-19 case severity and mortality in the population. However, the emergence and spread of new variant strains, and the relaxation of epidemic prevention policies, still led to multiple outbreaks peaki…
Critical national response in coping with Omicron variant in China, Israel, South Africa, and the United States
Based on this study, it seems that China and Israel adopted containment strategies, while South Africa and the United States adopted mitigation strategies. A rapid response is a powerful weapon against the Omicron epidemic. Vaccines alone will not get any country out of this crisis, and non-pharmacological measures should be used in addition to them. According to the SPO model, future work should consider the strengthening of emergency management…
Comparison of Covid-19 vaccine policies and their effectiveness in Korea, Japan, and Singapore
This study comparatively analyzed the COVID-19 vaccine policies and their effects in South Korea, Japan, and Singapore, and found that there is a common set of logical combinations behind the seemingly different strategies of these three countries. Therefore, in the process of combating COVID-19, countries can learn from the successful experience of combating the epidemic and continue to strengthen the implementation of vaccination programs, as w…
Efficiency and equity of bed utilization in China’s health institutions
China's investment in health funding in the field of health care has been on the rise in recent years. However, there still exists the situation of uneven investment in health expenses and inconsistent medical efficiency among regions. And change such a status quo can be further improved in terms of government, capital, human resources, technology, information system, and so on
How do density, employment and transit affect the prevalence of Covid-19 pandemic? A study of 3,141 counties across the United States
Spatial Accessibility Patterns to Public Hospitals in Shanghai
The spatial distribution of public hospitals is a crucial factor in patient access and thus important to health equity, especially amid the COVID-19 pandemic crisis. In China, a major issue is to improve accessibility to public health care in the face of the limited space for further growth of cities. Therefore, this study assesses the current spatial accessibility patterns to public hospitals in Shanghai, using point density analysis and the com…
Exploring land use functional variance using mobile phone derived human activity data in Shanghai
Land use functions can categorize places where people perform different socioeconomic activities. This classification plays an important role in urban management, policy making, and resource allocation. However, due to the rapid changes of built environment and living demands, human activities might vary significantly, in space and time, even within the same land use function as conventionally defined, impeding the formulation of targeted and use…
Containment strategy during the Covid-19 pandemic among three Asian low and middle-income countries
Background: COVID-19 has not been effectively controlled, seriously threatening people's health and socioeconomic development. This study aims to summarise the successful experiences and lessons in containment strategy learned from Asian Low- and Middle-Income Countries (LMICs) during the COVID-19 pandemic and analyse the effectiveness of their measures to provide lessons for LMICs in general. Methods: This is a retrospective study on the effecti…
Critical policies disparity of the first and second waves of Covid-19 in the United Kingdom
During the first and second waves of COVID-19, the UK implemented three lockdowns and managed to slow the spread of the pandemic. The UK's experience in mitigating the second wave proves that advancing COVID-19 vaccination needs to be accompanied by ongoing implementation of non-pharmacological interventions to reduce the transmission rate of infection. And a stricter lockdown ensures that the containment effect is maximized during the lockdown p…
Core policies disparity response to Covid-19 among BRICS countries
This study shows BRICS countries implemented different epidemic interventions. Containment strategy is more effective than intermediate strategy and mitigation strategy in limiting the spread of COVID-19. Especially when a strict containment strategy is implemented in an early stage, but premature relaxation of restrictions may lead to rebounding. It is a good choice to combat COVID-19 by improving the inclusiveness of intervention policies, deep…
Strategies comparison in response to the two waves of Covid-19 in the United States and India
There are differences between the epidemic prevention strategies adopted by the United States and India, especially India's containment strategies which helped it better control the epidemic in the early stage. However, the epidemic in the two countries is still severe. With the advent of virus mutants and the absence of immune barriers, it is meaningful that the two countries continue to take non-pharmacotherapy intervention measures and acceler…
