工作场所排斥与员工角色内外行为：归属感的中介作用

为考察工作场所排斥（包括上司排斥与同事排斥）与员工角色内行为和角色外行为（组织公民行为）之间的关系,以及归属感在上述关系中的中介作用,本研究采用问卷调查法,分两次对全职工作一年以上的员工进行施测,前后共获得247份有效匹配数据,经统计分析后发现：（1）上司排斥与同事排斥均显著地负向预测员工角色内外行为,即工作场所排斥水平越高,角色内行为和角色外行为的表现越差。（2）归属感在上司排斥、同事排斥与员工角色内行为之间发挥了完全中介作用,即工作场所排斥会破坏员工的归属感,最终降低角色内行为。（3）归属感在上司排斥和角色外行为的关系中发挥了完全中介作用,但在同事排斥与角色外行为的关系中仅存在部分中介作用,说明工作场所排斥在一定程度上会破坏员工的归属感,最终影响其角色外行为表现。     

Partially testing a process model for understanding victim responses to an anticipated worksite closure

This study partially tested a recent process model for understanding victim responses to worksite/function closure (W/FC) proposed by Blau [Blau, G. (2006). A process model for understanding victim responses to worksite/function closure. Human Resource Management Review, 16, 12-28], in a pharmaceutical manufacturing site. Central to the model are the Kubler-Ross [Kubler-Ross, E. (1969). On death and dying. New York: Macmillan] grieving stages, which have not been formally measured and applied to downsizing research. Following Blau (2006), individual grieving stages were successfully measured and clustered into more general grieving categories, i.e., negative (denial, anger, bargaining depression) and positive (exploration, acceptance). Across four waves of data 53 respondents constituted the complete data sample. The Time 1 personal factors had minimal impact on any type of response. However, Time 1 situational factors did have an impact, paced by higher perceived contract violation leading to greater strain, work incivility, organizational deviance, and intent to sue employer, and lower transactional obligations and employer endorsement. Earlier Time 2 grieving stages were used as individual antecedents in regression analyses to explain Time 3 (N = 77) victim responses (general strain, work incivility, interpersonal deviance, organizational deviance, transactional obligations, relational obligations) and also Time 4 (N = 53) prior to closure responses (intent to sue employer, employer endorsement). Within negative grieving, results indicated that greater anger was the most influential grieving stage, since it led to greater strain, work incivility, organizational deviance, and intent to sue, as well as lower transactional obligations and lower endorsement. Within positive grieving acceptance was the most influential, since it led to lower strain, lower work incivility, lower organizational deviance, and lower intent to sue. Study limitations and future research issues are discussed.

Ethnic differences in BMI, weight concerns, and eating behaviors: comparison of Native American, White, and Hispanic adolescents

Evidence suggests that substantial proportions of adolescents, regardless of ethnicity or gender, are engaged in excessive weight control behaviors. Crago and Shisslak (2003), however, have noted that small samples and poorly validated instruments have limited the value of previous ethnic difference studies. Using the McKnight Risk Factor Survey, we compared Native American, White, and Hispanic adolescents. Native students were divided into groups with one (NA-mixed) or two (NA) Native American biological parents. Surveys were completed by 5th through 10th grade students. BMI z-scores were significantly higher for boys and girls in the NA group, and boys in this group were significantly more engaged in weight control behaviors, including purging. A higher percentage of Native and Hispanic girls preferred a larger body size. BMI was positively correlated with weight and shape concerns and with weight control behaviors, regardless of ethnicity or gender. Overweight among Native adolescents may put them at greater risk for eating problems than their White peers.     

传统和现代视野中的自谦

自谦可以理解为是通过低调的自我呈现,以柔克刚、以弱胜强的和谐控制过程。它是文化背景、个体特征和情境变量交互作用的函数,也是由利益和情感共同驱动的。自谦主要出于"和合"、"远耻"、"隐显"的动机。自谦对于心理健康的积极意义在于,它是一种符合文化期待的自我实现方式。对于组织行为而言,自谦不能简单的理解为能改善员工自我评估和监管者评估间的一致性,而是有可能使问题更加复杂。

Can We Uncouple Neighborhood Disadvantage and Delinquent Behaviors? An Experimental Test of Family Resilience Guided by the Social Disorganization Theory of Delinquent Behaviors

Although the influence of neighborhood disadvantage on youth development of delinquent behavior is well established, findings from this research have yet to inform the development of family-centered prevention programming to protect youth from these erosive effects. The current paper examines the role of family integration in buffering the impact of social disadvantage in a sample of N = 298 families randomly assigned either to a control condition or to a family-based prevention program previously shown to enhance marriage and parenting. We first confirmed that neighborhood concentrated disadvantage predicted change in delinquent behaviors across the course of the study. Additionally, replicating prior work, parents participating in the Protecting Strong African American Families (ProSAAF) program, relative to those randomly assigned to the control group, significantly improved their use of effective communication strategies with each other and reduced ineffective conflict in front of youth. This resulted in a significant indirect effect of ProSAAF on change in youth delinquent behaviors. Furthermore, using mediated moderation analysis, the study tested the buffering effect of greater family integration, showing that experimentally produced change in interparental communication skills and the resulting reduction in youth exposure to parental conflict buffered the effect of neighborhood disadvantage on change in youth delinquent behaviors, supporting a mediated moderation model in which family environments buffer neighborhood effects.     

The effect of prenatal adversity on externalizing behaviors at 24 months of age in a high-risk sample: Maternal sensitivity as a moderator

The purpose of this study was to examine the moderating role of maternal sensitivity on the association between prenatal adversity and externalizing behaviors at 24 months of age in a diverse, high-risk sample. We hypothesized that among children with higher prenatal adversity, high maternal sensitivity would serve as a protective factor. Participants were 247 primarily low-income, diverse dyads. Results indicated a significant interaction effect of maternal sensitivity and prenatal adversity on externalizing problems. The association between prenatal adversity and externalizing behaviors was significant only among children who experienced low prenatal adversity, with higher maternal sensitivity associated with lower externalizing behaviors. These findings indicate that, in the absence of high prenatal risk, responsive and sensitive parenting can buffer children in an otherwise high-risk sample from the development of externalizing behaviors.     

Driver behaviour and traffic accident involvement among professional urban bus drivers in China

The present research aimed to investigate specific behaviors of professional urban bus drivers in China with the revised Driver Behavior Questionnaire (DBQ), and to define the relationships among various driving behaviors (errors, positives, inattention errors, violations), background information (age, years of driving experience, mobility, etc.), self-assessment, and traffic accident. To achieve such goals, the present research designed a four-dimensional DBQ with 20 items for professional urban bus drivers in China. The KMO coefficient of the whole scale was 0.835, and Bartlett’s test was statistically significant (p < 0.000), which demonstrated strong validity of the scale and should be suitable for factor analysis. The four loading factors accounted for 58.991%. In addition, the reliability and effectiveness of the present 20-item scales were measured. The coefficient of internal consistency-Cronbach’s alpha coefficient was 0.881 and the Cronbach’s Alpha Based on Standardized Items was 0.911. This showed that driving behavior scale of professional bus drivers in China was of high reliability and validity. The analysis showed that among the four factors, positive driving behaviors were significantly associated with errors, inattention errors and violations, respectively. Errors, inattention errors and violations correlated positively with each other. This verified that the correlation coefficient of each factor was medium and high, which indicated that the scale had good difference validity. The test content of the total scale was also highly consistent with the test content of each factor, which indicated that the revised scale had good standard related validity. According to the accident prediction model, the variables that significantly affected the occurrence of traffic accidents were daily driving time, positive driving behavior, SE2 (Driving safety), SE3 (Aberrant driver behaviors). The results showed that professional bus drivers often working overtime were most likely to have accidents. The probability of traffic accidents decreased by 53% for every unit of positive driving behavior frequency of professional bus drivers. The more they felt that they had the tendency of aberrant driving behavior, the more likely they were to have traffic accidents. To summary, the present research contributed to validating and improving the DBQ for professional urban drivers in China.     

催产素对产后抑郁症患者母性行为的调节作用

产后抑郁症是指女性分娩后一段时间内出现的严重抑郁发作现象。研究表明, 催产素不仅参与分娩过程和正常的母性行为表达, 也在调节产后抑郁的发病及患者的母性行为中起到了重要的作用。产后抑郁症患者的情绪和认知功能受损, 这可能导致了母性行为表达质量的下降; 催产素可以通过中脑边缘多巴胺系统来调控母性行为, 作用于内侧视前区(MPOA)来激活中脑腹侧被盖区(VTA)-伏隔核(NAc)环路从而影响伏隔核内多巴胺的分泌; 催产素对产后抑郁症中母性行为的调节机制可能是通过调节五羟色胺系统的功能来发挥抗焦虑作用, 也可能是通过与其它激素的交互作用来加速母性行为的表达。未来研究进一步明确催产素在中枢神经环路中的功能差异, 以及社会支持对产后抑郁症患者催产素的使用带来的影响。
