通常认为,城镇居民低碳出行受到内部心理性因素和外部结构性因素的共同影响,但是何种因素起主导作用,至今尚无定论。以江苏省镇江市城镇居民低碳出行调查所得的2212份有效数据为样本,运用系数集束化方法,从意愿与行为两个维度出发,比较上述两类因素对城镇居民低碳出行的影响强度。研究发现,在控制了社会人口因素的情况下,心理性因素和结构性因素显著影响城镇居民低碳出行意愿和行为,但是结构性因素的作用强度始终大幅度高于心理性因素。性别上的交互分析结果表明,这一结论具有较强的稳健性。可见,城镇居民低碳出行尽管受到心理性因素驱动,但是主要受制于结构性因素。因此,相较于提升城镇居民的心理性因素,破除外在因素的结构性束缚,是提高城镇居民实践低碳出行更为有效的途径。

目的了解中国中小学生睡眠状况及其与抑郁症状的关系,为改善中小学生睡眠和降低抑郁症状发生率提供科研证据。方法利用2018和2020年中国家庭追踪调查(CFPS)中4 232名在校中小学生数据,使用自报方式了解睡眠状况,使用简易流调中心抑郁量表(CES-D8)测量抑郁症状。采用方差分析、χ^(2)检验、多元线性回归分析和限制性立方样条模型分析中小学生睡眠状况及其与抑郁症状的关联。结果 2018—2020年中国中小学生平均学习日、休息日夜晚睡眠时长分别为(7.96±1.38)(9.30±1.51)h,睡眠不足报告率依次是42.75%,11.41%;1 921名(45.39%)中小学生报告有午睡习惯,567名(13.40%)中小学生午睡>1.0 h/d;2 997名(70.82%)中小学生报告周末补觉,595名(14.06%)中小学生补觉>2.0 h/d。多元线性回归分析结果显示,控制其他因素后,学习日夜晚睡眠不足、休息日夜晚睡眠不足、周末补觉>2.0 h/d均与中小学生抑郁症状呈正相关(β值分别为0.40,0.39,0.41,P值均<0.05)。限制性立方样条分析结果显示,调整性别、年龄、城乡、地区、自评健康和体质量指数等因素后,学习日夜晚睡眠时长、休息日夜晚睡眠时长和午睡时长与中小学生抑郁症状均呈非线性剂量反应关系(P总趋势值均<0.05,P非线性值均<0.05),最佳时长分别约为9.0 h, 10.0 h和40 min。结论中小学生夜晚睡眠不足、午休不科学和周末补觉过长均是抑郁症状的重要风险因素。应积极改变中小学生的不良睡眠行为,降低其抑郁症状发生风险。

数学模型的精度特性和稳健性特性对数控机床热误差补偿技术在实际中的实施性影响不容忽视。对数控加工中心关键点的温度和主轴z向的热变形量采用多种算法建立了预测模型,对不同算法拟合精度进行分析。同时进行全年热误差跟踪试验,获得了机床在不同环境温度和不同主轴转速的试验条件下的敏感点温度和热误差值。以此为基础,对各种预测模型的预测精度进行比较验证不同模型的稳健性。结果表明,多元线性回归算法的最小一乘、最小二乘估计模型以及分布滞后模型在改变试验条件时预测精度下降,而基于支持向量回归机原理的热误差补偿模型仍能保持较好的预测精度,稳健性强。这为数控机床热误差补偿模型的选择提供了具有实用价值的参考,具有很好工程应用性。
