应激与海马

综述了近年来应激对海马形态和功能影响及海马对应激(HPA轴)调节的研究进展。研究表明,由于海马参与应激的感知、整合与评价,参与HPA轴应激反应,应激影响其结构与功能;而海马又可通过负反馈调节,抑制HPA轴的过度应激反应。但长期慢性应激则可削弱这种抑制作用,加重海马结构与功能的损害。     

Adolescents Coping with Poverty-Related Family Stress: Prospective Predictors of Coping and Psychological Symptoms

Examined prospective associations among poverty-related family stress, coping, involuntary stress reactivity, and psychological symptoms in a sample of 79 rural, low-income adolescents. Poverty-related family stress predicted adolescents’ anxious/depressed and aggressive behavior 8 months later, controlling for prior symptoms. Coping interacted with initial symptoms and involuntary stress reactivity to predict changes in symptoms over time, showing that primary and secondary control coping were most strongly associated with changes in symptoms for adolescents with low initial symptoms and involuntary stress reactivity. The only significant predictor of coping over time was prior coping, suggesting that coping is not symptom-driven and may be somewhat trait-like. Implications for interventions and additional research are offered. Assistant Professor, University of Denver. Received PhD from University of Vermont.

Coping with Interpersonal Stress and Psychosocial Health Among Children and Adolescents: A Meta-Analysis

This meta-analysis examines the relationship between active coping and psychosocial health among youth. Results from 40 studies of coping with interpersonal stress were synthesized using a random-effects model. Four areas of psychosocial functioning were examined: externalizing and internalizing behavior problems, social competence, and academic performance. The magnitude of the relationship between active coping and psychosocial functioning was small, with correlations ranging from 0.02 for internalizing behavior to 0.12 for academic performance. Mean effects were moderated by stressor controllability: youth who used active coping in response to controllable stressors had fewer externalizing problems and higher social competence, as compared to those who used active coping in response to uncontrollable stressors. Implications for primary prevention programs and directions for future research on child and adolescent coping are discussed.

Skeletal Indicators of Stress: A Component of the Biocultural Profile of Undocumented Migrants in Southern Arizona,

The ability of forensic anthropologists in the United States to distinguish the remains of foreign nationals from those of American citizens may be crucial to the identification process. This study adds new criteria for identifying Hispanic foreign nationals in southern Arizona to those previously outlined by Birkby et al. (J Forensic Sci 53, 2008, 29) in the “cultural profile.” Skeletal indicators of nonspecific stress were evaluated in undocumented border crossers (UBCs) at the Pima County Office of the Medical Examiner and in documented American samples. Odds ratios show significant associations between UBC status and the presence of porotic hyperostosis and enamel hypoplasias, which are, respectively, 7.9 and 3 times more prevalent among UBCs. These findings are consistent with disparities in access to adequate nutrition and health care during childhood. In conjunction with context and other biocultural factors, the presence of these conditions should prompt practitioners to consider that unidentified remains may represent foreign nationals.     

Post-traumatic effects in policing: perceptions,stigmas and help seeking behaviours

This study explored the relationships between perceptions, stigmas and support with help seeking amongst police officers. A total of 421 web surveys were completed by constables from a large municipal police force in Canada. The most significant finding was the relationship between officers feeling comfortable disclosing distressing personal information and seeking help from others. Help was most commonly sought from respondents’ friends (at work and outside) and family members. Respondents shared information with their direct supervisors only when there was a strong, reciprocal relationship between them. Implications for future research and practice for help seeking in police occupations are discussed.

基于语音情感分析系统的语音压力测谎

目的探究语音情感分析系统(Layered Voice Analysis,LVA)在不同情况下的表现,并通过分析数据找出影响系统识别率的因素。方法设置两种不同场景对20名研究对象进行提问,并录音。通过LVA语音系统对语音样本进行分析,使用SPSS统计软件对系统生成的参数进行统计分析。结果在未告知研究对象实验真相的情况下LVA语音系统平均识别率为91.75%,要远高于研究对象在知情情况下的识别率。在询问过程中,当未涉及敏感问题时,随着时间的推移研究对象的心理压力逐渐减小。结论LVA语音系统具有良好的情感分析和识别能力,可为司法工作提供参考。     

The Impact of Mobbing and Job-Related Stress on Burnout and Health-Related Quality of Life: The Case of Turkish Territorial State Representatives

This study is to determine whether stress and mobbing are directly related to burnout; and whether burnout adversely affects the health-related quality of life (HRQoL) of Turkish territorial state representatives (TSRs). The results established that stress was positively and significantly associated with the burnout of TSRs, while mobbing was positively and significantly related to the burnout. HRQoL was negatively associated with the burnout. The findings showed that propositions of the theoretical frameworks of the study and literature were consistent with one another.
