Investing in College Readiness
A growing volume of research shows college promise programs increase the likelihood that students enroll in and complete college. Place-based promise programs provide a guaranteed college scholarship for students who attend a specified school district. We examine the societal benefits and costs of a place-based scholarship program in rural Arkansas, the El Dorado Promise. Our cost framework treats tuition payments as a cash transfer that shifts t…
Staffing and Resource Allocation in College Access Reform
Objective: Dual credit (DC), or dual enrollment, is college-level coursework that confers credit toward both high school graduation and a postsecondary degree. As DC has grown rapidly across the country, this study provides needed evidence about how these courses shift resources and cost burdens among community colleges, school districts, and families. Methods: We use economic evaluation methods to assess the cost of DC across three delivery mode…

Valuation of ecosystem services from forests in Chinese rural areas based on forest resource investment
Forest resources provide rural areas with abundant products and ecosystem services. However, due to difficulties and shortcomings in assessing the ecosystem service value of these resources in rural areas, investors or funding institutions often lack a comprehensive understanding of their true value. Consequently, challenges such as difficulties in securing rural forestry guarantees, limited loan amounts, and inadequate compensation standards hav…
Effects of rural-to-urban migration on healthcare utilization of middle-aged and older adults
Background An increasing number of middle-aged and older adults are migrating from rural to urban areas for employment, to care for their younger generation and due to old age. As these age groups move into urban areas, their healthcare service utilization are directly related to their health status and basic rights to survival. It also places higher demands on China’s healthcare service provision. Objectives This study aims to examine effects of…
Exploring influenza vaccination coverage and barriers to influenza vaccine uptake among preschool children in Fuzhou in 2022
Background: Children are vulnerable to influenza virus due to their developing immune systems, particularly children aged 6 months-5 years (preschool children). To improve the uptake of influenza vaccine in preschool children, it is important to determine the influencing factors of Chinese parents/guardians' (P/Gs) intention and behavior for children to receive. We implemented an investigation to determine coverage of influenza vaccination in pre…
Interparental conflict and adolescents’ suicidal ideation
Background Suicidal ideation is the most significant risk factor for suicide, and suicide is the third leading cause of death among people aged 15 to 19 years. Interparental conflict has been shown to be associated with adolescents’ suicidal ideation, but the reasons for this association remain underexplored. We investigated whether adolescents’ life satisfaction accounts for this relationship, and whether perceived teacher support moderates the …
Understanding the Relationship Between Educational Leadership Preparation Program Features and Graduates’ Career Intentions
Globally, many school systems face leadership shortages and challenges in building strong principal pipelines, making career intentions to pursue school leadership a critical area of study.

Between a Rock and a Hard Place
This article explores the educational challenges faced by migrant children in China, examining their experiences in both inflow cities and hometowns. Drawing on 94 in-depth interviews conducted in 2022 with returned migrant children and adults, as well as an empirical survey involving 1,865 returned migrant children and 344 teachers across 8 county-level cities in 4 provinces in 2023, the study reveals significant findings. Migrant children in Ch…
Plant species selection and participatory community co-design are essential in balancing ecosystem services and disservices in urban areas
Balancing the benefits and disservices of urban green infrastructure is critical for sustainable city planning. While urban vegetation provides ecosystem services such as air quality improvement and heat reduction, it can also contribute to air pollution through the emission of biogenic volatile organic compounds, and pollen can exacerbate respiratory health issues and allergies within communities. Chicago’s environmental and health disparities m…

Rethinking China’s emerging case law system
This paper examines China’s emerging case law system through an empirical analysis of more than 10,000 court judgments issued between 2019 and 2021. It challenges prevailing academic views that Guiding Cases are ‘de facto binding’ on Chinese courts and that China’s case law system could be interpreted through a common law lens. Instead, the study shows that the Chinese approach is characterised by distinct objectives, methodologies, and applicati…
Advancements in low-carbon economic growth research from an energy consumption perspective
Extensive fossil fuels and energy utilization have ensured the sustained development of modern society's economy. However, they have also led to a continual increase in greenhouse gas emissions, notably carbon dioxide, ultimately resulting in climate change and environmental deterioration. Investigating how to sustain low-carbon economic growth (LCEG) by adjusting energy consumption holds paramount theoretical and practical significance. This stu…

Bridge to bigpush or backwash? Market integration, reallocation and productivity effects of Jamuna Bridge in Bangladesh
We study the effects of Jamuna Bridge in Bangladesh that reduced the average trade costs by 50% and connected 26 million people by road to the capital city. We use a difference-in-difference design where the isolated Padma hinterland constitutes the comparison. Balance tests for an array of economic characteristics support the parallel trends assumption. The bridge led to economic revival in the Jamuna hinterland with increased agricultural produ…

Prevalence of metabolic syndrome in a cohort of Chinese schoolchildren
MetS was highly prevalent amongst obese children and adolescents in this cohort, regardless of the definition used. Central obesity is the key player in the clustering of metabolic risk factors in children, supporting the new IDF definition. Moreover, our findings suggest that a common factor may underlie MetS. Leptin/adiponectin ratio as a possible component of MetS deserves further consideration

Alleviated environmental constraints and restructured fungal microbiome facilitate aggregate formation and stabilization in coastal mudflat saline soil amended by sewage sludge
Soil aggregates are important drivers of soil productivity. However, the relative importance of soil abiotic and biotic agents in driving aggregate formation and stabilization remain largely unexplored, especially in coastal mudflat saline soils. We amended saline soil with sewage sludge at rates of 0, 30, 75, and 150 t ha −1 to investigate the effects of sewage sludge on the particle size distribution and stability of soil aggregate and the unde…
The association between exposure to PM 2.5 components from coal combustion and mortality in female breast cancer patients
PM 2.5 components may promote the development of breast cancer and increase the risk of mortality. This study aims to investigate the associations between long-term exposure to PM 2.5 components and multiple causes of mortality among women with breast cancer living in Inner Mongolia, China. We constructed an Inner Mongolia cohort of 33 952 breast cancer patients from 2012 to 2021 using data from the Inner Mongolia Regional Health Information Plat…
