Understanding Present-Day Racialized Inequities in Urban Heat
From physical surfaces to human-centric heat stress
Heat exposure connects the built environment and public health, directly shaping the livability and sustainability of urban areas. Fully understanding the spatial heterogeneity of heat exposure and its driving factors is therefore a vital prerequisite for climate-adaptive urban planning. However, most planning-oriented studies rely on land surface temperature (LST), and whether LST adequately represents human heat exposure and how it differs from…
Uncovering nonlinear urban factors of homelessness
Urban homelessness is a complex issue rooted in structural inequalities and spatial disparities, significantly affecting urban life and well-being. Existing research often relies on survey-based or linear regression methods, which are limited in scope, coverage, and their ability to capture nonlinear associations. This study addresses these gaps by combining homeless incident reports from New York City’s 311 service with multi-source urban big da…
Assessing nighttime homeless shelter accessibility and its socioeconomic associations in Los Angeles
Mapping pedestrian network level outdoor heat hazard distributions in Philadelphia
With the rise of global temperature, many cities are suffering from more and more frequent extreme heat in hot summers. Quantitative information on the spatial distributions of urban heat has become more and more important for extreme heat mitigation and adaptation in cities. This study first investigated the fine-level heat hazard distributions at the sidewalk and building block level from the pedestrian perspective in Philadelphia, Pennsylvania…
Measuring exposure to extreme heat in public transit systems
Hyperlocal heat stress around bus stops in Philadelphia
The Urban Heat Island (UHI) effect significantly impacts public transit users, particularly those waiting at bus stops, where prolonged exposure to extreme heat poses health risks. Despite increasing attention to climate resilience, limited research has focused on hyperlocal, pedestrian-level thermal stress at bus stops or its relationship with the surrounding urban environment. To address this gap, we generated hourly 1-meter resolution Universa…
Quantifying seasonal bias in street view imagery for urban form assessment
Street view imagery (SVI), with its rich visual information, is increasingly recognized as a valuable data source for urban research. Particularly, by leveraging computer vision techniques, SVI can be used to calculate various urban form indices (e.g., Green View Index, GVI), providing a new approach for large-scale quantitative assessments of urban environments. However, SVI data collected at the same location in different seasons can yield vary…
Do environmental attitudes and personal characteristics influence how people perceive their exposure to green spaces
Background: This study explores the relationship between perceived and objective greenspace exposure, and how sociodemographic traits and environmental attitudes influence peoples' perceptions of greenspace. Methods: We leveraged a cross-sectional survey on greenspace exposure among residents of Denver, CO that ran from November 2019 through April 2021. We measured objective greenspace using the average NDVI (normalized difference vegetation inde…
Interpretable spatial machine learning insights into urban sanitation challenges
Urban sanitation is critical for public health, with the management of human feces presenting significant challenges in growing urban areas. While prior research has concentrated on the health impacts of fecal contaminants, the spatial distribution and determinants of open defecation in urban contexts have received less attention. To address these gaps, this study proposed an interpretable spatial machine learning framework integrating Geographic…
Sensitivity and vulnerability to summer heat extremes in major cities of the United States
Many cities are experiencing increases in extreme heat because of global temperature rise combined with the urban heat island effect. The heterogeneity of urban morphology also leads to fine-scale variability in potential for heat exposure. Yet, how this rise in temperature and local variability together impacts urban residents differently at exposure-relevant scales is still not clear. Here we map the Universal Thermal Climate Index, a more comp…
Comparison of different spatial temperature data sources and resolutions for use in understanding intra-urban heat variation
In this study, we investigate the compatibility of specific vulnerability indicators and heat exposure data and the suitability of spatial temperature-related data at a range of resolutions, to represent spatial temperature variations within cities using data from Atlanta, Georgia. For this purpose, we include various types of known and theoretically based vulnerability indicators such as specific street-level landscape features and urban form me…
Subjective and objective measures of streetscape perceptions
Subjective or objective measures of street environment, which are more effective in explaining housing prices
Examining runner's outdoor heat exposure using urban microclimate modeling and GPS trajectory mining
Socioeconomic and spatial inequalities of street tree abundance, species diversity, and size structure in New York City
Examining the spatial distribution and temporal change of the green view index in New York City using Google Street View images and deep learning
As an important part of the urban ecosystem, urban trees provide various benefits to urban residents. It is therefore important to examine the spatial distribution and the temporal change in urban tree canopies. Different from traditional overhead view remote sensing-based methods, street-level images, which present the most common view that people have of greenery, provide a more human-centric way to quantify street tree canopies. This study map…
Analyzing the obstruction effects of obstacles on light pollution caused by street lighting system in Cambridge, Massachusetts
Artificial light has transformed urban life, enhancing visibility, aesthetics, and increasing safety in public areas. However, too much unwanted artificial light leads to light pollution, which has a negative effect on public health and urban ecosystems, as well as on the aesthetic and cultural meanings of the night sky. Some of the factors interfering with the estimation of light pollution in cities are urban features, such as the presence of tr…
Investigating the spatial distribution of resident’s outdoor heat exposure across neighborhoods of Philadelphia, Pennsylvania using urban microclimate modeling
The distribution of greenspace quantity and quality and their association with neighbourhood socioeconomic conditions in Guangzhou, China
Residential Greenspace and Urban Adolescent Substance Use
While urban greenspace is increasingly recognized as important to mental health, its role in substance use is understudied. This exploratory study investigates the interaction of greenspace with peer network health, sex, and executive function (EF) in models of substance use among a sample of disadvantaged, urban youth. Adolescents and their parents were recruited from a hospital in the mid-Atlantic region of the U.S. Residential greenspace at th…

Associations between Body Mass Index and Urban “Green” Streetscape in Cleveland, Ohio, USA
Public health researchers are increasingly interested in assessing the impact of neighborhood environment on physical activities and chronic health issues among humans. Walkable streets and proximity to green space have long been believed to promote active lifestyles in cities, which contribute to positive health outcomes among residents. Traditionally, urban environmental metrics were calculated at the area level to describe the physical environ…

The manner in which features of the built environment, such as walkability and greenness, impact participation in recreational activities and health are complex. We analyzed survey data provided by 282 Ottawa adults in 2016. The survey collected information on participation in recreational physical activities by season, and whether these activities were performed within participants' neighbourhoods. The SF-12 instrument was used to characterize t…

Measuring exposure to extreme heat in public transit systems
China urban competitiveness in industrialization
There is a consensus in China that industrialization, urbanization, globalization and information technology will enhance China’s urban competitiveness. We have developed a methodology for the analysis of urban competitiveness that we have applied to China’s 25 principal cities during three periods from 1990 through 2009. Our model uses data for 12 variables, to which we apply appropriate statistical techniques. We are able to examine the competi…
The Progress of Humanity and Women's Liberation
The change in women's historical circumstances and social status has no direct connection with the development of social formations in classical Marxism. It is, however, intimately linked to human progress. Up to the present, social development has undergone five stages, yet the change in women's status overall has passed through three eras: the age of matriarchy, the age of slavery, and the age of liberation. The age of women's liberation was in…
The Contradictory Aspects of Women Cadres' State of Mind and Social Adjustments
In the thirty-odd years since Liberation, the ranks of women cadres in China have grown to a considerable size. Working at posts all over the country, women cadres in leadership positions and those of the rank and file have increased from 345,000 in 1951 to 5,300,000 in 1983. Nevertheless, the strength of women cadres assuming leading posts in party and administrative organizations is comparatively weaker than that of women professionals in other…
