  • Assessing and Optimizing Urban Dynamic Resilience to Extreme Rainfall from Shock to Recovery

    Open AccessLinmei Zhuang, Ming Wang et al.ARTICLEInternational Journal of Disaster…2026

    Climate change has intensified extreme rainfall events, challenging progress toward SDG 11’s urban resilience targets. Current assessment methods often neglect dynamic recovery processes and regional precipitation disparities. We propose a three-phase framework combining interpretable machine learning (ML) and factorial experiments, using the Prep_shock index that integrates standardized rainfall intensity, capital exposure, and historical probab…

  • Assessment and Mapping of Extreme Ice Accretion Damage on Electricity Infrastructure Due to Freezing Rain in China

    Open AccessJunfei Liu, Ming Wang et al.ARTICLEInternational Journal of Disaster…2026

    Extreme weather events, particularly freezing rain (FR), pose significant threats to electricity infrastructure through ice accretion on transmission lines and towers. This study conducted a comprehensive national-scale assessment of FR impacts on China’s electricity infrastructure using an enhanced methodological framework. We integrated high-resolution (0.1°) gridded FR data spanning 2000–2019 with infrastructure data from OpenStreetMap, develo…

  • Global patterns of reservoir sedimentation and overlooked risks in small reservoirs

    Open AccessKai Liu, Chenyu Fan et al.ARTICLENature Sustainability2026

    Reservoir sedimentation is an escalating threat to global water security. While most existing assessments focus on large, well-managed reservoirs, they overlook the vast and vulnerable network of smaller reservoirs, which hampers our understanding of global sedimentation risks. Here we present a high-resolution global assessment of reservoir sedimentation in over 550,000 reservoirs, ~95% of which are <1 km2, based on a physics-guided machine lear…

  • Global burden and trends of non-communicable diseases among children and adolescents from 1990 to 2021

    Open AccessYing Chen, Yudan Long et al.ARTICLEFrontiers in Public Health2026

    Background Comprehensive analyses of non-communicable diseases (NCDs) in children and adolescents that disentangle age, period, and cohort effects, assess health system efficiency, and project future trends remain limited. This study aims to address these gaps using data from the Global Burden of Disease Study 2021. Methods Utilizing data from GBD 2021, we analyzed age-standardized rates (ASRs) of prevalence, incidence, mortality, and disability-…

  • Complex network-based detection and forecasting of high-intensity tropical cyclones

    Open AccessZiyu Jiang, Kaiwen Li et al.ARTICLEInternational Journal of Disaster…2026

    Accurate detection and forecasting of tropical cyclone tracks using limited climate variables and data is challenging. Here, we propose an innovative time-evolving complex network approach for detecting and forecasting high-intensity tropical cyclones (HITCs) based on mean sea level pressure and relative vorticity at 850 hPa. This approach enables us to successfully reproduce the tracks of HITCs of the Western North Pacific, achieving a mean dete…

  • Quantitative evaluation and resource optimization strategy for ancient and notable trees conservation efficacy

    Open AccessKai Liu, Shouqiang Wang et al.ARTICLETrees Forests and People2026

    To address the lack of a quantitative assessment framework for evaluating the conservation efficacy of ancient and notable trees, as well as the absence of a scientific basis for optimal resource allocation, this study developed an evaluation model based on the “Tree-Environment-Human” triad criterion framework. The model was applied to assess the conservation efficacy of 71,578 ancient and notable trees in Sichuan Province, and resource optimisa…

  • Development of main effect DIF and interactive DIF detection method in cognitive diagnosis assessments

    Kai Liu, Z Y Guo et al.ARTICLEActa Psychologica Sinica2026

    摘要: 在认知诊断评估中, 项目功能差异(DIF)检测是评估其测验公平性以及测量效度的重要技术手段。然而, 现有的认知诊断DIF检测方法局限于单一协变量视角下的主效应DIF检测, 对于由多个协变量交互作用引发的交互式DIF尚缺乏有效的检测手段。针对这一局限, 研究借鉴递归分割技术的核心思想, 提出了一种能够在认知诊断评估中同时检测主效应DIF和交互式DIF的新方法(记为ISRPM)。模拟研究结果表明, ISRPM不仅在主效应DIF检测中的整体表现与传统方法大体相当, 更重要的是, 其在交互式DIF检测方面的性能表现优于传统方法。实证研究则进一步支持了该方法的可用性, 结果显示, ISRPM与传统DIF检测方法在检测结果上具有较高一致性, 并在识别交互式DIF方面展现出潜在优势。总体而言, ISRPM的提出有望进一步提升认知诊断DIF检测精度, 并促进认知诊断评估在心理与教育测评实践中的推广与应用

  • Developmental trajectories of vocabulary and logical thinking skills across adolescence

    Open AccessShuyan Mei, Kai Liu et al.ARTICLEBMC Public Health2026

    Adolescence is a critical developmental period characterized by rapid neurobiological maturation and substantial changes in higher-order abilities, including vocabulary and logical thinking. Although prior research has documented general age-related improvements in these abilities, most studies have relied on cross-sectional or variable-centered designs, limiting insight into developmental heterogeneity and obscuring distinct developmental trajec…

  • Personality characteristics of Chinese adolescents with excessive screen time

    Open AccessJunsong Fei, Leilei Liang et al.ARTICLESocial Behavior and Personality…2026

    The use of digital technologies is inevitable in modern society, but their overuse is a problem that is worthy of public attention. This study explored the personality traits that cause proneness to excessive screen time, applying latent profile analysis to build personality profiles using the Big Five personality traits and assessing the psychological entitlement of 4,874 Chinese adolescents. We also constructed parallel mediation models to exam…

  • The digital economy and urban-rural income inequality in China

    Open AccessLingran Zhang, Xinyuan Wang et al.ARTICLESustainable Futures2026Referencias: 4

    Income inequality is a bottleneck constraining China's sustainable development. The development of the digital economy generates new opportunities to narrow this gap and change the urban-rural dichotomy. Using provincial panel data in China from 2011 to 2020, this study examines the effect of digital economic development on urban–rural income inequality and investigates the moderating and threshold roles of new urbanization. High-dimensional fixe…

  • Heavy DIY Activities as a Potential Preventative for Stress Urinary Incontinence

    Open AccessKai Liu, Xiaogang Lian et al.ARTICLEAmerican Journal of Men s Health2025

    Physical activity is associated with stress urinary incontinence (SUI). The genetic causality of this association remains unclear. This study used the Mendelian randomization (MR) method to explore the potential causal relationship between physical activity and SUI risk using heavy do-it-yourself (DIY), light DIY, strenuous sports, walking for pleasure, and other exercises as proxies. We selected single nucleotide polymorphisms associated with ph…

  • Changing Families

    Marc K Chan, Kai LiuARTICLEJournal of Labor Economics2025

    We develop a tractable economic framework to study the impact of family structure on children’s cognitive and noncognitive outcomes. Combining a sequential choice model with panel data on both biological parents, irrespective of subsequent relationship status, and on social fathers and a set of exclusion restrictions, we identify the unobserved heterogeneity of biological families and examine child skill formation via a control function approach.…

  • Can a voluntarist approach to social security extend protection to gig workers? Evidence from the platform-based food-delivery sector in China

    Open AccessHao Zhang, Kai LiuARTICLEJournal of Industrial Relations2025

    Gig workers are in a precarious position in the absence of employer-sponsored social insurance programs in countries that adopt the Bismarck model of social security. China, among others, has attempted to address this challenge by including gig and other self-employed workers on a voluntary, self-sponsorship basis. Drawing on data collected from platform-based food-delivery workers complemented by self-compiled data on local labour policies acros…
