Urban adults' engagement in nature education and its interplay with everyday lived experiences: A case study from Shenzhen, China

open access: yesPeople and Nature, Volume 8, Issue 3, Page 741-753, March 2026.
Abstract Currently, scholarship on education to foster connectedness with nature primarily focuses on children. As adults likewise face the disconnection from nature and play a key role in influencing children, it is important to understand how they perceive, engage in, and benefit from relevant programmes.

基于物元分析法的电力变压器套管健康状态评估

open access: yesGaoya dianqi, 2015
套管故障率往往高于变压器本体,准确评估套管健康状态对提高变压器整体运行可靠性十分重要。文中基于物元分析理论提出了套管健康状态的评估方法。以试验检测数据为基础,综合考虑巡视检查与维护历史状态参量,构建了套管健康状态评估的层次型指标体系;采用层次分析法(AHP法)确定指标初始权重,并根据指标数据变化量、利用信息熵对试验类指标的初始权重进行修正。基于物元理论构建了套管健康状态的评估物元,考虑到定量指标测量干扰及定性指标主观判断所带来的误差,采用一个数据区间来表征指标状态 ...

基于CCTV和XGBoost的管道缺陷评估及预测

open access: yesJingshui jishu
【目的】排水管道系统作为城市的“静脉血管”,其健康状况直接关系到城市的安全运行与可持续发展。针对管网隐蔽性强、运行环境复杂导致检测困难的问题,本文旨在构建一套科学合理的管网健康评估模式,并利用机器学习技术预测未检测管道的健康状况,为排水管道的智能化管理与安全运维提供理论依据和可靠工具。【方法】以南方某城市近5年的闭路电视(CCTV)检测数据为基础,选取管道结构性缺陷作为核心评价因子,并充分考量缺陷随时间演化的恶化趋势,综合评估管网健康程度。同时,引入极端梯度提升(XGBoost ...

A Tale of Two Programs? Stigma and Administrative Burdens in CHIP and Medicaid

open access: yesWorld Medical &Health Policy, Volume 18, Issue 1, March 2026.
ABSTRACT One contributing factor to undersubscriptions is administrative burdens. To explore whether program stigma affects attitudes about administrative burdens, a survey (N = 2204) was fielded to assess differences in attitudes about seven policies decreasing administrative burdens and two policies increasing administrative burdens.
