农民工的工作退缩行为：基于多重嵌入和身份压力的视角

2.9亿农民工的工作退缩行为——为减少工作和组织角色而有意采取的行为(回避工作和降低努力、迟到缺勤、离职等)影响重大。为此, 本研究以资源保存理论作为“伞”理论, 整合了多重嵌入和身份压力的视角, 构建了一个全面预测农民工的工作退缩行为的模型。在该模型中, 提出了同时包含隐性和显性的工作退缩行为的测量指标体系; 构建了农民工在城市和家乡的多重嵌入对不同工作退缩行为的预测关系, 以及“农村人”和“城市人”的双重身份压力经由农民工在城市的多重嵌入对工作退缩行为的间接预测效应。本研究基于农民工样本的特异性, 构建了一个“背景化”的全面预测工作退缩行为的理论模型, 不仅弥补了微观层面农民工研究的理论空白, 也丰富了身份、多重嵌入和工作退缩行为领域的理论和文献。     

Speech presentation cues moderate frontal EEG asymmetry in socially withdrawn young adults

Socially withdrawn individuals display solitary behavior across wide contexts with both unfamiliar and familiar peers. This tendency to withdraw may be driven by either past or anticipated negative social encounters. In addition, socially withdrawn individuals often exhibit right frontal electroencephalogram (EEG) asymmetry at baseline and when under stress. In the current study we examined shifts in frontal EEG activity in young adults (N=41) at baseline, as they viewed either an anxiety-provoking or a benign speech video, and as they subsequently prepared for their own speech. Results indicated that right frontal EEG activity increased, relative to the left, only for socially withdrawn participants exposed to the anxious video. These results suggest that contextual affective cues may prime an individual's response to stress, particularly if they illustrate or substantiate an anticipated negative event.     

4-8年级学生社交淡漠与同伴接纳的交叉滞后回归分析

摘要：用同伴提名和班级戏剧对小学4年级至初中二年级787名儿童进行一年的追踪研究,采用交叉滞后设计,考察了社交淡漠与同伴接纳的相互预测关系。结果发现：（1）同伴接纳与社交淡漠呈显著负相关;（2）社交淡漠在一年时间内呈现出高度的稳定性。测试时间与性别、年级的交互作用显著,在一年时间里,小学男生社交淡漠水平有所减少、女生社交淡漠水平有所增加,而初中男生社交淡漠水平有所增加、女生社交淡漠水平有所减少;（3）二元交叉滞后回归分析结果表明,社交淡漠与同伴接纳的关系模式存在显著的性别差异。对于男生,前测的社交淡漠可以显著预测后测的同伴接纳,而前测的同伴接纳不能显著预测后测的社交淡漠。女生则呈现完全相反的模式。     

Stigma and hostility towards pregnant smokers: Does individuating information reduce the effect?

Australia is at the forefront of tobacco control, yet 17% of Australian women smoke during pregnancy. Negative attitudes to smoking are intensified when the smoker is pregnant, consistent with a discourse that encourages surveillance of pregnant women. Such overt anti-smoking attitudes create a context which may make it difficult for pregnant smokers to seek assistance to stop. However, there is little evidence on the extent to which pregnant smokers are stigmatised by community members. We used vignettes to examine the degree of smoking-related stigma expressed by 595 Australian university students who rated a woman, described as a mother who was smoking or not, and pregnant or not. Further, we examined whether provision of individuating information reduced the degree of stigma. Mothers described as smokers were rated more negatively than those not, particularly if they were pregnant: smokers were perceived as unhealthy, and also as bad mothers. Provision of individuating information slightly reduced these effects. These findings support the view that smokers – particularly if pregnant – are subject to negative moral judgement. Our findings contribute to the ethical debate about stigma-inducing tobacco control efforts, and suggest that anti-smoking campaigns that contextualise smoking in pregnancy might reduce stigma and assist cessation.     

Initial responses to the first dose of nicotine in novel smokers: The role of exposure to environmental smoking and genetic predisposition

Background: Sensitivity to initial smoking constitutes an early predictor of the risk of dependence. We investigated the role of exposure to smoking (by parents, siblings, and peers) and reward-related candidate gene polymorphisms (OPRM1 A118G, DRD2 TaqlA and DRD4?bp VNTR) in adolescents’ responses to initial smoking.

Methods: We used cross-sectional survey data and saliva samples from 171 Dutch students who had never inhaled on a cigarette (mean age: 13.9?years). The outcome measure was adolescents’ self-reported responses to initial smoking.

Results: Exposure to peer smoking was associated with increased liking (OR?=?1.74, CI?=?1.13–2.70) and more pleasant sensations (β?=?.21, p?=?.01). Exposure to maternal smoking was associated with less unpleasant sensations (β?=??.20, p?=?.01). Adolescents carrying the G-variant of the OPRM1 A118G polymorphism were more likely to report liking (OR?=?2.50, CI?=?1.09–5.73) and adolescents homozygous for the C-variant of the DRD2 TaqlA polymorphism reported less unpleasant sensations (β?=?.18, p?=?.04).

Conclusion: Although preliminary, these findings suggest that exposure to environmental smoking and polymorphisms in the OPRM1 and DRD2 gene may affect initial sensitivity to nicotine, an early phenotype of the risk of dependence. In the future, collaborative efforts to combine data from multiple studies in meta-analyses are needed to improve accuracy of estimated effects in genetic studies.     

Perceived social support,coping, and symptoms of distress in American and Spanish students

Abstract

The aim of this study was to test whether coping responses mediated the influence of perceived social support on symptoms of anxiety/depression, social withdrawal, and aggressive behavior in American (N=349) and Spanish students (N=437). Participants completed measures of perceived support, social stress, coping, and distress. Coping partially mediated relations between perceived support and distress, with coping mediation most evident in individuals facing high levels of social stress. Decreased use of disengagement coping by individuals with high perceived support appears to partially explain the protective value of perceived social support. Multiple group covariance structure analysis showed that models linking perceived support, coping, and distress were very similar across cultures, suggesting that the mechanisms underlying decreased risk for individuals with high perceived support may be relatively independent of cultural context, and that interventions designed to increase perceived support and decrease disengagement could be appropriate in both cultures.     

Evidence That Episodic Memory Impairment During Tobacco Abstinence Is Independent of Attentional Mechanisms

Previous studies have demonstrated reductions in episodic memory during nicotine withdrawal. However, these studies have been unable to dissociate memory reductions from losses in attention associated with tobacco abstinence. In the present study, the authors sought to determine whether episodic memory reduction is a primary effect of nicotine withdrawal during tobacco abstinence. Heavy smokers were tested when smoking normally and following 24 hrs of abstinence. Participants were tested with a recognition memory task in which items were studied under full and divided attention conditions. Forward digit span and backward digit span were also included as control measures. Withdrawal was associated with a reduction in memory performance that was independent of attention at encoding. The authors conclude that impairment of episodic memory is a primary effect of nicotine withdrawal during tobacco abstinence. Further research is required to determine if this is associated with continued use of tobacco and cessation failures.     

Infant Expressions in an Approach/Withdrawal Framework

Since the introduction of empirical methods for studying facial expression, the interpretation of infant facial expressions has generated much debate. The premise of this article is that action tendencies of approach and withdrawal constitute a core organizational feature of emotion in humans, promoting coherence of behavior, facial signaling, and physiological responses. The approach/withdrawal framework can provide a taxonomy of contexts and the neurobehavioral framework for the systematic, empirical study of individual differences in expression, physiology, and behavior within individuals as well as across contexts over time. By adopting this framework in developmental work on basic emotion processes, it may be possible to better understand the behavioral principles governing facial displays, and how individual differences in them are related to physiology and behavioral function in context.     

Severe Social Withdrawal: Cultural Variation in Past Hikikomori Experiences of University Students in Nigeria,Singapore, and the United States

Hikikomori (social withdrawal that lasts six months or longer) is a growing problem among Japanese adolescents and young adults, with recent estimates that approximately 1% of Japanese youths will suffer from an episode of hikikomori in their lifetimes. What remains unclear is whether hikikomori is a culture-bound syndrome or a condition impacting youths around the globe. Hence, the self-reported prevalence and psychosocial correlates of past experiences with hikikomori were examined in cross-sectional samples of university students from Singapore (n?=?147), Nigeria (n?=?151), and the United States (n?=?301). Following tests of measurement invariance, comparisons showed that past experiences with hikikomori were related to elevated levels of current loneliness and depressive symptoms in each sample. However, analyses also revealed evidence of cultural variation in both the prevalence and the psychosocial correlates associated with past experiences of hikikomori, which taken together, provide preliminary evidence that the culture-bound characterization of hikikomori may not be appropriate.
