Effect of pressure on the mechanical and dynamical stability of NaAlSi

The effects of pressure on the mechanical and dynamical stability of NaAlSi have been fully investigated by first-principles calculations within the generalised gradient approximation (GGA). The obtained results show that the optimised lattice constants, atomic positions and elastic constants at ambient pressure are in good agreement with the available experimental and theoretical data. The lattice constants decrease monotonically with increasing pressure. The elastic constant C₁₁, C₁₂, C₁₃, C₃₃ and C₆₆ increase while C₄₄ decreases with increasing pressure. It is found that NaAlSi is mechanically unstable when the pressure is above 25.97?GPa. The phonon-dispersion curves along several high symmetry lines are obtained. The phonon frequencies at the Z point decrease with increasing pressure and completely soften to zero at 27.52?GPa, further confirming the structural instability of NaAlSi.     

具身认知视角下的道德隐喻表征

道德隐喻已成为道德心理学研究的热点问题,随着具身认知相关理论的兴起,道德隐喻的具身研究逐渐展开。目前,具身道德隐喻的维度主要包括空间、温度、洁净、颜色、明暗、触觉、味觉、嗅觉等。具身道德隐喻的相关理论解释主要包括概念隐喻理论、具身认知理论、知觉符号理论和架构理论。今后的具身道德隐喻应更多的探讨跨文化的差异性,丰富道德隐喻具身维度的内容以及各维度之间的相关性,同时要引入道德隐喻的影响机制分析。

Building up resources in the relationship between work–family conflict and burnout among firefighters: moderators of guanxi and emotion regulation strategies

This study investigated the moderating effects of supervisor–subordinate “guanxi” alongside relevant emotional regulation strategies, including cognitive reappraisal and expressive suppression, undertaken by 402 firefighters experiencing burnout caused by work–family conflict, as revealed through the application and analysis of the job demands–resources model. According to the regression model for the moderating effects, high levels of supervisor–subordinate guanxi may improve the relationship between work–family conflict and burnout, while frequent suppression of expressivity may enhance this relationship. Moreover, when supervisor–subordinate guanxi is high, cognitive reappraisal may effectively mitigate the relationship between work–family conflict and burnout. To this end, both guanxi and cognitive reappraisal are crucial for supporting emotional regulation in the workplaces of ethnic Chinese societies.     

Effect of Poverty on Mental Health of Children in Rural China: The Mediating Role of Social Capital

Underprivileged children are a relatively special vulnerable group in rural China, but the relationship between poverty and children’s mental health has been rarely examined. This study aimed to investigate the effect of poverty on children’s mental health and the mediating role of social capital in their family, peer, school, and community level. Data used in this study were collected in 2015 from a school-based survey of 1314 children in grades 4–9 through a multi-stage cluster random sampling method in Xiushui, a poverty-stricken city in Mainland China. The result of structural equation modeling indicated that poverty elicited a significant predictive effect on children’s negative and positive mental health. Family social capital and peer social capital played intermediary effects between poverty and children’s mental health. However, the mediating effects of school and community social capital are not significant. The implications of these findings on theory, social policy, and social work services were also discussed.

     

Study on a Christian Chinese sample: sense of self-worth,well-being and locus of control

The purpose of this study was to explore Chinese Christians’ sense of self-worth, well-being, locus of control and the correlations between these variables. One hundred and two Chinese Christians with a range of 18–40 years old were surveyed by the Scale of Self-worth, Chinese version of General Well-Being Scale and internal–external Locus of Control Scale. A control group of 134 Chinese non-Christians participated in the same survey. Christians scored lower on locus of control and higher on self-worth than the non-Christians. No significant general well-being difference was between the Christian and non-Christian samples. The correlations were significant between locus of control and self-worth/general well-being (negative) and between self-worth and general well-being (positive). Results suggest that Christians experience better self-worth and tend to be internals on locus of control.     

Perfectionism mediated the relationship between brain structure variation and negative emotion in a nonclinical sample

In maladaptive respects, perfectionism reflects an individual’s concern over making mistakes and doubting the quality of his or her own actions excessively, which would affect one’s emotion. However, little is known about the neural mechanisms associated with the perfectionism and negative affect. In this study, voxel-based morphometry was performed to identify the brain regions underlying individual differences in perfectionism, which was measured by the Chinese Frost Multidimensional Perfectionism Scale (CFMPS), in a large sample of nonclinical young adults. Our results showed that the two subdimensions of the perfectionism, concern over mistakes (CM) and doubts about actions (DA), were both positively correlated with the self-reported anxiety and depression as well as the gray matter volume (GMV) in the anterior cingulate cortex (ACC), a pivotal brain region in cognitive control, affective state, and regulation. Moreover, CM, DA, and organization scores were respectively correlated with distributed brain regions involved in multiple cognitive and emotion processes. Our results furthermore revealed that the score of DA acted a mediational mechanism underlying the relationship between the GMV of ACC and self-rating negative affect (anxiety and depression). Taken together, these results might suggest the neuroanatomical basis of perfectionism and the association among the perfectionism, negative emotion, and brain architecture. This study emphasized that perfectionism could play a crucial role in the arousal of negative affect.     

Individual differences in skewed financial risk-taking across the adult life span

Older adults are disproportionately targeted by fraud schemes that advertise unlikely but large returns (positively skewed risks). We examined adult age differences in choice and neural activity as individuals considered risky gambles. Gambles were symmetric (50% chance of modest win or loss), positively skewed (25% chance of large gain), or negatively skewed (25% chance of large loss). The willingness to accept positively skewed relative to symmetric gambles increased with age, and this effect replicated in an independent behavioral study. Whole-brain functional magnetic resonance imaging analyses comparing positively (vs. negatively) skewed trials revealed that relative to younger adults, older adults showed increased anticipatory activity for negatively skewed gambles but reduced activity for positively skewed gambles in the anterior cingulate and lateral prefrontal regions. Individuals who were more biased toward positively skewed gambles showed increased activity in a network of regions including the nucleus accumbens. These results reveal age biases toward positively skewed gambles and age differences in corticostriatal regions during skewed risk-taking, and have implications for identifying financial decision biases across adulthood.

Resistance to Cultural Intervention: Formation of Inhibitory Collective and children’s Self-Defensive Regulation in a Chinese School

A sequel to the previous article “Roots of Excellence: The Releasing Effect of Individual Potentials through Educational Cultural Intervention in a Chinese School” (in press), the present study is on the unexpected reversal phenomena in the process of cultural intervention. The goal of the intervention is to construct the dynamics of Jiti (well-organized collective in Chinese) through creative activities to promote students’ development. In the intervention, the releasing effect (Wu et al. 2016) emerged as well, but the teacher’s concern about worsening discipline and academic performance evoked and reinforced his habitual notions and practices of education, turning the joint activities into a way of strengthening discipline. The energy that had been discharging at the beginning of the intervention was inhibited, so that many more problematic behaviors took shape. The whole class formed an inhibitory atmosphere, within which pupils formed self-defensive regulation strategies. By comparing with the productive collective in which intervention was effective and analyzing this unexpected reversal process, we can not only see pupils’ self-construction status in the inhibitory culture but illuminate the formation of the teacher’s resistance to educational and cultural transformation as well. Resistance is originated from teachers not being able to interpret pupils’ inner developmental needs but instead anxious about the ongoing problems.
