Marital satisfaction of Chinese under stress: Moderating effects of personal control and social support

Stressful life events, personal control, and social support were examined relative to marital satisfaction among 1749 participants in seven Chinese cities. Stressful life events were categorized as life crises and life transitions. Life crises, rather than transitions, negatively predicted the marital satisfaction of Chinese. The moderating effects of personal control were found among women, but not men, and occurred only in the relationship between marital satisfaction and life crises, not life transitions. Social support buffers the negative effects of life crises on marital satisfaction. The results extend family stress‐coping theory in specifying two coping resources for Chinese marriages under stress.     

Want a tip? Service performance as a function of emotion regulation and extraversion

Surface acting and deep acting with customers are strategies for service performance, but evidence for their effectiveness is limited and mixed. We propose that deep acting is an effective strategy for most employees, whereas surface acting's effect on performance effectiveness depends on employee extraversion. In Study 1, restaurant servers who tended to use deep acting exceeded their customers' expectations and had greater financial gains (i.e., tips) regardless of extraversion, whereas surface acting improved tips only for extraverts, not for introverts. In Study 2, a call center simulation, deep acting improved emotional performance and increased the likelihood of extrarole service behavior beyond the direct and interactive effects of extraversion and other Big Five traits. In contrast, surface acting reduced emotional performance for introverts and not extraverts, but only during the extrarole interaction. We discuss implications for incorporating traits into emotional labor research and practice.     

The development and validation of the Relational Self-Esteem Scale

According to the tripartite model of the self (Brewer & Gardner, 1996), the self consists of three aspects: personal, relational, and collective. Correspondingly, individuals can achieve a sense of self-worth through their personal attributes (personal self-esteem), relationship with significant others (relational self-esteem), or social group membership (collective self-esteem). Existing measures on personal and collective self-esteem are available in the literature; however, no scale exists that assesses relational self-esteem. The authors developed a scale to measure individual differences in relational self-esteem and tested it with two samples of Chinese university students. Between and within-network approaches to construct validation were used. The scale showed adequate internal consistency reliability and results of the confirmatory factor analysis showed good fit. It also exhibited meaningful correlations with theoretically relevant constructs in the nomological network. Implications and directions for future research are discussed.     

A Multilevel Investigation of Missing Links Between Transformational Leadership and Task Performance: The Mediating Roles of Perceived Person-Job fit and Person-Organization Fit

Purpose  

This study explores whether follower perceived need-supply (N-S) job fit, demand-ability (D-A) job fit, and person-organization (P-O) fit mediate the relationships between individual-level, unit-level transformational leadership (TFL), and follower task performance.     

澳门和东北地区夫妻沟通模式与婚姻满意度研究

采用问卷调查法对澳门（118对）和东北地区（266对）夫妻进行研究,以检验两地夫妻沟通模式的差异,及其对婚姻满意度的主客体效应。结果发现：澳门夫妻双方回避沟通显著少于东北夫妻;两地夫妻报告的妻子要求/丈夫回避行为多于丈夫要求/妻子回避行为;建设性沟通对两地夫妻婚姻满意度正向预测力最强;要求/回避沟通只对澳门夫妻的婚姻满意度有负向预测力。两地妻子的建设性沟通都能显著正向预测丈夫的婚姻满意度,而只有东北地区丈夫的建设性沟通能正向预测妻子婚姻满意度。     

孕中期胎儿出生缺陷产前筛查2321例分析

探讨孕妇孕中期血清标志物产前筛查唐氏综合征为主的先天缺陷,应用酶联免疫法检测孕中期血清标记物(AFP、Fβ-HCG),2321例孕妇中检出各类高风险人群共260例,其中DS高风险有219例,占筛查总数的9.4%;NTD风险37例,占筛查总数的1.6%;18及13三体高风险4例,占0.2%,确诊异常胎儿9例,其中染色体异常7例,脊柱裂2例。孕中期应用母血清二联生化指标进行产前筛查是可行的。结合产前诊断是减少出生缺陷发生的重要手段之一。     

自我参照与朋友参照对人格特质记忆的影响

采用记忆研究范式,本研究比较了自我参照编码和朋友参照编码对人格特质记忆的影响。结果发现,自我参照编码和朋友参照编码的再认错误率均小于语义编码,而两者之间的差异并不显著。这表明,和自我参照一样,朋友参照也会对人格特质的记忆起到促进作用;同时,再认反应时的结果表明,褒义人格特质的记忆效果好于贬义特质。     

Matrix derivatives and its applications in statistics

The scalar values of differentials rather than symbolic derivatives are treated here. This approach simplifies the differential calculus in statistics because, often, the linear representations of differentials in statistics (1) are complicated, (2) depend on the bases used, (3) can be obtained by the scalar values on elements of a given basis, and (4) are not necessary for many problems of finding maxima and minima. Among others, a product rule is obtained in a very general and simple form. The results are applied to certain problems in multivariate statistical analysis that are useful to psychology and other behavioral sciences.
