The Indirect Effect of Child Maltreatment Severity on Adult PTSD Symptoms through Anxiety Sensitivity

Although the rate of posttraumatic stress disorder (PTSD) among survivors of child maltreatment is high, individuals differ in symptom severity and many do not experience clinically significant levels of psychopathology. The present study tested the indirect effects of child maltreatment severity on adult PTSD, suicidal ideations, and alcohol dependence via anxiety sensitivity. A sample of 336 participants (mean age of 22.81 years, SD = 8.93; 70.2% female) completed an online survey of child abuse and neglect, anxiety sensitivity, PTSD symptom severity, suicidal ideation severity, and alcohol dependence severity. The results revealed significant indirect effects of child maltreatment on PTSD symptom severity through cognitive and social concerns, but not physical concerns. No direct or indirect effects were demonstrated for suicidal ideations or alcohol dependence severity. These findings elucidate mechanisms in the robust relationship between child maltreatment and adult PTSD symptoms and can potentially inform future research on mechanisms of change in psychotherapy.     

Sensitivity Analysis Using Risk Measures

In a quantitative model with uncertain inputs, the uncertainty of the output can be summarized by a risk measure. We propose a sensitivity analysis method based on derivatives of the output risk measure, in the direction of model inputs. This produces a global sensitivity measure, explicitly linking sensitivity and uncertainty analyses. We focus on the case of distortion risk measures, defined as weighted averages of output percentiles, and prove a representation of the sensitivity measure that can be evaluated on a Monte Carlo sample, as a weighted average of gradients over the input space. When the analytical model is unknown or hard to work with, nonparametric techniques are used for gradient estimation. This process is demonstrated through the example of a nonlinear insurance loss model. Furthermore, the proposed framework is extended in order to measure sensitivity to constant model parameters, uncertain statistical parameters, and random factors driving dependence between model inputs.     

Multi-ethnic school environment from the school leader’s perspective: challenges and approaches to improve multi-cultural competency among teachers in Malaysia

This study aims to identify the challenges and approaches to improve a multicultural competency among teachers in multi-ethnic schools environment based on school leaders’ perspective. Data collection method used in this study is qualitative method. A total of nine school leaders from the states of Kedah, Penang, and Perak were included in the interview session. The results of this study show that the challenges faced by teachers in practicing the multicultural competency are lack of experience toward cultural diversity. A late exposure to cultural diversity makes it difficult for teachers to accept and adapt in a multi-ethnic school environment. The approaches suggested by school leaders to improve the multicultural competency are as follows: (1) Courses on cultural diversity should be organized to enhance the knowledge about cultural diversity; (2) the development of more open and better policy for education system in Malaysia in order to prepare teachers with a higher multicultural competency for teaching students from diverse ethnic and cultural groups; (3) an early exposure to cultural diversity in order to increase the multicultural competency, especially during teaching practicum.     

加强礼仪教育，促进大学生人际关系和谐

礼仪教育，有利于提高大学生容纳意识、尊重意识、悦纳他人的能力。目前，大学生礼仪教育、规范的缺失．在一定程度上影响了大学生人际交往和谐，因此，高校要通过教育引导、行为规范、文化渗透等渠道加强大学生礼仪教育，培养具有良好心态、得体风度、高雅气质的高素质人才，为和谐社会建设做出贡献。     

动员式治理中的政府组织传播：南京个案

政府组织传播与社会动员具有内在联系，政府组织推行其政策、主张的过程是一种动员式治理行为，是通过组织间和组织外传播与动员对象进行的有效互动。其中，组织间传播是一种基于人情投资的资源动员，而组织外传播则主要通过人际传播起作用。政府组织在面对面的人际动员实践中既存在“培养典型”等传统群众运动的路径依赖，也利用了情感等多种因素，此外还引入了国家正式权力进行惩戒动员。     

Preschoolers' Attachment to Mother and Risk for Adjustment Problems in Kindergarten: Can Teachers Make a Difference?

Based on attachment theory, two aims were addressed. Firstly, we tested whether close teacher–child relationships may buffer children who are less securely attached to their mothers against negative outcomes, such as aggressive behavior. Secondly, our study evaluated whether teacher sensitivity may protect less securely attached children against forming less close relationships with their teachers. In a sample of 127 children, mother–child attachment was observed in preschool. In kindergarten, teacher sensitivity was observed, and teacher–child closeness and child aggressive behavior were rated by the teacher. Results of multilevel hierarchical regression analyses first showed that with high teacher–child closeness, less securely attached children are no longer at risk for more aggressive behavior. Secondly, it was found that with high teacher sensitivity, less securely attached children are no longer at risk for developing less close relationships with their teachers.     

董事会非正式层级与高管薪酬契约有效性

董事会治理是影响高管薪酬契约有效性的关键,已有研究主要从董事会结构层面展开,缺乏对董事会内部运作机制与高管薪酬契约有效性关系的具体分析。基于董事权威不平衡性的治理效应视角,系统考察了董事会非正式层级与高管薪酬契约有效性的逻辑关系及其作用机理,得出了一些具有重要价值的结论,主要包括:1.董事会非正式层级对高管薪酬业绩敏感性具有显著的负向调节作用,且主要体现在业绩下滑的样本公司中,表明董事会非正式层级对高管薪酬契约的影响主要体现在公平性和风险匹配性方面。2.只有当最高层级董事身份为独立董事时,董事会非正式层级对高管薪酬业绩敏感性具有显著的负向调节效应。3.董事会非正式层级增强了高管薪酬的行业和地区薪酬敏感性,进一步验证了董事会非正式层级的社会公平效应。论文的研究为从微观运作层面理解董事会治理和高管薪酬契约有效性提供一种新的视角和结论,对于优化董事会治理和提高高管薪酬契约有效性等均具有重要借鉴意义。

Symmetrical Design of Experiment in Global Sensitivity Analysis Based on ANOVA High-dimensional Model Representation

This article reviews symmetrical global sensitivity analysis based on the analysis of variance of high-dimensional model representation. To overcome the computational difficulties and explore the use of symmetrical design of experiment (SDOE), two methods are presented. If the form of the objective function f is known, we use SDOE to estimate the symmetrical global sensitivity indices instead of Monte Carlo or quasi-Monte Carlo simulation. Otherwise, we use the observed values of the experiment to do symmetrical global sensitivity analysis. These methods are easy to implement and can reduce the computational cost. An example is given by symmetrical design of experiment.     

Local influence diagnostics for incomplete overdispersed longitudinal counts

We develop local influence diagnostics to detect influential subjects when generalized linear mixed models are fitted to incomplete longitudinal overdispersed count data. The focus is on the influence stemming from the dropout model specification. In particular, the effect of small perturbations around an MAR specification are examined. The method is applied to data from a longitudinal clinical trial in epileptic patients. The effect on models allowing for overdispersion is contrasted with that on models that do not.
