The current longitudinal study is the first comparative investigation across low‐ and middle‐income countries (LMICs) to test the hypothesis that harsher and less affectionate maternal parenting (child age 14 years, on average) statistically mediates the prediction from prior household chaos and neighborhood danger (at 13 years) to subsequent adolescent maladjustment (externalizing, internalizing, and school performance problems at 15 years). The sample included 511 urban families in six LMICs: China, Colombia, Jordan, Kenya, the Philippines, and Thailand. Multigroup structural equation modeling showed consistent associations between chaos, danger, affectionate and harsh parenting, and adolescent adjustment problems. There was some support for the hypothesis, with nearly all countries showing a modest indirect effect of maternal hostility (but not affection) for adolescent externalizing, internalizing, and scholastic problems. Results provide further evidence that chaotic home and dangerous neighborhood environments increase risk for adolescent maladjustment in LMIC contexts, via harsher maternal parenting. 相似文献

We set out to investigate the mediating roles of depression, resilience, smoking, and alcohol use, in the relationship between potentially traumatic life events and objective and subjective, physical and mental health in a single study. A face-to-face, population-based survey was conducted in Hong Kong (N = 1147). Information on health conditions and traumatic life events was obtained, and participants completed measures of subjective physical and mental health, depression, and resilience. Smoking and drinking were not significant mediators of the relationship between life events and both objective and subjective health. Depressive symptomatology was found to mediate the relationship between life threatening illness and subjective physical health, the relationship between abuse (physical and sexual) and subjective mental health, and the relationship between the death of a parent/partner and subjective mental health. Resilience was found to mediate the relationships between multiple traumatic life events and subjective physical and mental health. Our results indicate that psychological factors rather than biological are important mediators of the relationship between life events exposure and health. Our findings provide evidence that depressive symptomatology has a mediating role only in the case of specific potentially traumatic life events and that resilience is only a critical factor in the face of exposure to multiple traumatic events, rather than single events. Our results also indicate that behavioural factors, such as smoking and drinking, are not significant mediators of the relationship between life events and health. 相似文献

为了克服网络虚拟性的影响,网络商铺往往通过提升网站临场感以弥补购物体验不足的问题。那么,网站临场感是否会对女性消费者这一细分群体产生影响呢?本研究从网站临场感的视角出发,以女大学生为研究对象、服装网站为实验材料,采用实验法研究了网站临场感对女性网络购买意愿的影响及其发生机制。研究发现:网站临场感对女性网络购买意愿具有显著的正向影响;网站临场感可以通过风险感知和沉醉感的中介作用对女性网络购买意愿产生影响,且该中介作用包含了三条路径,即风险感知的中介作用、沉醉感的中介作用以及风险感知和沉醉感的链式中介作用。 相似文献

This study tested whether the presence of an attractive face would influence individuals' honesty. In 2 experiments, 225 participants were asked to predict the outcome of computerised coin‐flips and to self‐report the accuracy of their predictions. Self‐reports were made in the presence of a facial photo of a female who had been rated before the experiment as high attractive, middle attractive or low attractive by other volunteers. Participants were rewarded based on their self‐reported (not actual) accuracy. The results showed that subjects tended to give more dishonest self‐reports when presented with middle or low attractive facial images than when presented with high attractive images, with self‐reported accuracy being significantly higher than the random level. The results of this study show that presented with an attractive face, subjects tend to engage in behaviours that conform to moral codes. 相似文献

There have been a number of publications in recent years on generalising the AGM paradigm to the Horn fragment of propositional logic. Most of them focused on adapting AGM contraction and revision to the Horn setting. It remains an open question whether the adapted Horn contraction and Horn revision are inter-definable as in the AGM case through the Levi and Harper identities. In this paper, we give a positive answer by providing methods for generating contraction and revision from their dual operations. Noticeably, we cannot apply the Levi and Harper identities directly in such methods as the Horn fragment does not fully support negation. To overcome this difficulty, a Horn approximation technique called Horn strengthening is used. We show that Horn contraction generated from Horn revision is always plausible whereas Horn revision generated from Horn contraction is, in general, implausible and, to regain plausibility, the generating contraction has to be properly restricted. 相似文献

研究为探索常驻高海拔地区军人心理健康水平如何随社会年代变迁而改变,运用了横断历史元分析的方法,对1993年至2013年38篇采用90项症状自评量表(SCL-90)的文献调查数据进行分析,考察了11454名常驻高海拔地区军人在该量表上9个因子得分随年代变化的趋势.结果发现:(1)SCL-90的7个因子均值与年代负相关,且不受期刊类型等的影响.20年来,7个因子下降了5%~15%不等.其中,强迫变化最大,抑郁、焦虑、人际敏感、偏执和精神病性均变化明显.这说明,常驻高海拔地区军人心理健康虽有所波动但整体水平逐步提升,变化幅度大致属于中等程度.(2)当年军费占GDP比值、居民消费水平指数与SCL-90部分因子均值负相关显著;5年前的居民消费水平指数与7个因子显著负相关.这说明,国防建设的经济投入和居民消费水平可能是影响常驻高海拔地区军人心理健康水平的重要因素. 相似文献
