社会经济地位与老人身体功能健康的关系——以锻炼和医保为中介变量

社会经济地位是影响健康不平等的根本要素之一,行为论和环境论对影响机制提供了不同的理论视角。文章采用2014年"中国老年健康影响因素调查"(CLHLS)数据,运用Logit回归模型和KHB方法,分析社会经济地位对中国老人身体功能健康的影响,并以个体行为方面的锻炼和制度环境方面的医疗费支付方作为中介变量,来分析影响发挥的作用机制。研究发现,社会经济地位的不同维度对老人身体功能健康的影响具有不同方向,教育和经济状况与老人身体功能健康显著正相关,但只有富裕老人与贫困老人身体功能健康的显著性差异,部分是通过锻炼这一中介因素实现的。锻炼和医疗费支付方这两个中介变量部分抵消了职业和居住地对老人身体功能健康差异的直接影响,发挥了压抑效应,且锻炼比医疗费支付方的贡献大。文章表明,在社会经济地位对老人身体功能健康的影响机制上,行为论和环境论都有一些解释力,但个体因素的锻炼比环境因素的医保制度中介作用大。

Depressing effect of phenoxyl acetic acids on flotation of minerals containing Ca^(2+)/Mg^(2+) gangues

Phenoxyl acetic acids were applied to determine their depressing effect on minerals containing Ca2+/Mg2+ gangues. Calcite, mixture of calcite and fluorite, and nickel ore were used in the flotation. And the depression mechanism was studied by the determination of contact angle, zeta potential, adsorptive capacity of collector, and IR analysis as well. It is found that 0.1 mmol/L of phenoxyl acetic acid derived from pyrogallol or gallic acid exhibits strong depressing ability on calcite in almost zero yields at pH value of 9.8, and calcite can be depressed in the flotation of calcite/fluorite mixture for approximate 87% yield of fluorite. The flotation result of practical nickel ore containing serpentine indicates that these two depressants may also show better depression performance to serpentine than traditional depressants such as sodium fluosilicate and carboxylmethyl cellulose. Analysis for the depression mechanism reveals that there exists strong chemical interaction between the depressants and minerals.

心理咨询师的成人依恋、情绪体验和共情能力的关系研究

目的:探讨心理咨询师的成人依恋、情绪体验和共情能力的关系。方法:采用亲密关系经历量表(ECR)、情绪体验问卷(RDEES)、人际反应指针(IRI)对心理咨询师施测,共收回222份有效问卷。结果:①成人依恋、情绪体验和共情能力之间两两相关显著。②情绪体验完全中介了依恋回避与共情能力的关系,情绪体验压抑了依恋焦虑对共情能力的影响。结论:应该关注心理咨询师的成人依恋对共情能力的影响,以及情绪体验在其中所起的作用,促进其职业发展。
