基于驾驶适宜性检测的沙漠公路驾驶员生理、心理特性研究

采用驾驶适宜性检测仪器,在塔克拉玛干沙漠公路沿线进行驾驶员心理、生理特性的现场测试。结果表明,沙漠公路特殊的环境条件,使得驾驶员表现出有别于一般绿洲公路的心理和行为特性,其主要表现在:驾驶员动体视力较静体视力的平均降幅为44.75%,最高竟达到93%;速度估计和复杂反应时间均小于全国平均;复杂反应错误次数和处置判断错误次数均高于绿洲公路。灰色关联分析表明,沙漠公路驾驶员的年龄、驾龄、驾车时间以及气温与驾驶员的各项生理、心理特性指标都具有较强的相关性,关联度最高达到0.837,其中驾车时间对各项指标的影响最大。     

Psychological consequences among adults following the 1999 earthquake in Athens, Greece

One year after the 7 September 1999 earthquake in Athens, Greece, we investigated the psychological consequences among 305 individuals (71 per cent female) residing in the settlements of Ano Liosia Municipality. Adaptability was difficult (63 per cent) due to limited space (50 per cent). Insecurity feelings were predictive of difficult adaptability (chi2= 29.8, p<0.0001) and were common (63 per cent) among married subjects, independent of age (chi2= 5.0, odds ratio (OR): 0.49, 95 per cent confidence interval (CI): 0.26-0.90). Eighty per cent expressed stress feelings, mainly nervousness/tension (60 per cent). Adaptability (chi2= 5.3, OR: 0.5, 95 per cent CI: 0.27-0.9), age (chi2= 6.5, OR: 1.03, 95 per cent CI: 1.01-1.06), and female gender (chi2= 4.7, OR: 0.48, 95 per cent CI: 0.25-0.90) were independent predictors of stress feelings. The majority (55 percent) developed sleep disorders, chiefly insomnia (60 percent). Adaptability problems were the only predictor of sleep disorders (chi2= 6.4, OR: 0.5, 95 per cent CI: 0.33-0.87). Psychiatric medication use increased after the earthquake.     

Impact of psychological risk factors on disaster rescue operations: the case of Italian volunteers

This paper reports on research into the characteristics of emergency rescue workers, with a focus on psychological distress. We present the results of a study of volunteers from the Italian national civil protection programme. A questionnaire was administered to 2,576 subjects from all over Italy. Most respondents were men, mostly unemployed, whose average level of education was higher than that among most Italian volunteers. Many were poorly endowed with basic skills, with large differences according to geography. Many expected to convert their volunteer activities into permanent jobs. Using this data, we employed a logistical regression model to analyse the risk of low, moderate and severe psychological distress symptoms, including anxiety and panic attacks, during rescue operations. The results indicate that some rescuers are particularly vulnerable to distress. The highest risk factors pertained to volunteers from southern Italy whose training is inadequate, who have little experience of emergency work and who play subordinate roles in small teams that lack psychological support services.     

Evaluation of the use of psychometric scales in human–wildlife interaction research to determine attitudes and tolerance toward wildlife

Studies evaluating human–wildlife interactions (HWIs) in a conservation context often include psychometric scales to measure attitudes and tolerance toward wildlife. However, data quality is at risk when such scales are used without appropriate validation or reliability testing, potentially leading to erroneous interpretation or application of findings. We used 2 online databases (ProQuest Psych Info and Web of Science) to identify published HWI studies that included attitude and tolerance. We analyzed these studies to determine the methods used to measure attitudes or tolerance toward predators and other wildlife; determine the proportion of these methods applying psychometric scales; and evaluate the rigor with which the scales were used by examining whether the psychometric properties of validity and reliability were reported. From 2007 to 2017, 114 published studies were identified. Ninety-four (82%) used questionnaires and many of these (53 [56%]) utilized a psychometric scale. Most scales (39 [74%]) had at least 1 test of reliability reported, but reliance on a single test was notable, contrary to recommended practice. Fewer studies (35 [66%]) reported a test of validity, but this was primarily restricted to structural validity rather than more comprehensive testing. Encouragingly, HWI investigators increasingly utilized the necessary psychometric tools for designing and analyzing questionnaire data, but failure to assess the validity or reliability of psychometric scales used in over one-third of published HWI attitude research warrants attention. We advocate incorporation of more robust application of psychometric scales to advance understanding of stakeholder attitudes as they relate to HWI.     

Mediating effects of psychological safety in the relationship between team affectivity and transactive memory systems

In this research, we develop a framework for understanding the emergence of transactive memory systems (TMS) in project‐based teams characterized by different levels of group level positive affectivity (PA) and negative affectivity (NA). With a focus on enhancing understanding of the means of transmission, we test the mediating role played by group level psychological safety (PS) in the relationship between team affectivity and TMS. From a sample of 107 software implementation project teams, in a lagged field study, we find support for a mediated model in which high group NA, but not group PA, promotes environments psychologically unsafe for interpersonal risk‐taking (low PS) and which are negatively associated with TMS. This study extends prior research on the differential effects of PA and NA, by contributing to the limited research on group affectivity, environmental antecedents of TMS, and the mediating role of PS for predicting group level transactive processes and structures.

大型活动中人群的应急行为研究综述

为完善对大型活动的应急处理能力,预防应急事件发生,研究人群在应急状况下的行为反应及疏散中的行为决策。从应急管理和救援的角度,对国内外现有文献进行梳理,分析大型活动背景下人群的应急行为和疏散时间、应急疏散模型、应急逃生的调查实证、交通及人流行为特征和组织与疏散方案等方面的研究现状,指出当前国内外大多数文献较多地侧重于利用计算机模拟火灾环境以研究单一建筑体中人的应急疏散行为,行为调查以事后调查为主,对火灾环境之外的其他突发应急事件及个体行为特征的研究等较少。同时,基于试验性研究的应急心理反应对于行为的影响研究,以及群体信任和他人行为对于行为决策的影响等可以作为未来研究的重要方向。     

突发公共事件应急心理干预机制的构建

突发公共事件往往会对人造成多方面的伤害,特别是对人的心理影响不容忽视,为突发公共事件受害人提供心理援助和应急心理干预,有助于社会公众及当事人正确对待突发事件的影响,对和谐社会的构建和安定的社会局面也有重要的意义。该文提出了加强突发公共事件国家心理预警和应急社会心理干预机制构建的重要作用,分析了心理干预机制构建的“四大因素”和基本原则;以抢险救援人员、社会公众、灾难性事故与事件的受害人为应急心理干预的对象,介绍了应急心理干预的基本任务与侧重点。最后,在分析的基础上,提出应将重大灾害的心理危机干预列入突发公共事件的应急预案。     

Leader–member exchange and job performance: The effects of taking charge and organizational tenure

We theorized and tested the mechanisms by which leader–member exchange (LMX) quality is associated with job performance. The results obtained using 212 employee–supervisor pairs from eight Chinese companies indicated that LMX quality had an indirect and positive relationship with taking charge via psychological empowerment and had an indirect and positive relationship with job performance via taking charge. In addition, organizational tenure significantly moderated the relationship between taking charge and job performance, such that the positive effect of taking charge on job performance became weaker as organizational tenure increased. Furthermore, organizational tenure significantly moderated the indirect positive relationship between LMX quality and job performance via taking charge; the indirect effect became weaker as organizational tenure increased. These results suggest that organizations should encourage managers to develop high‐quality LMX with their subordinates, which may make them feel more empowered and engage in more taking charge, and result in better job performance.

地铁应急疏散恐慌程度模型研究

为研究地铁应急疏散情况下人员恐慌程度,建立地铁应急疏散恐慌程度模型。首先根据恐慌心理量表和调查问卷得到恐慌程度影响因素及其分类,并确定各影响因素权重值。在北京地铁军博站进行应急疏散模拟试验。根据试验数据修正模型中相关事故经历因素,得到地铁应急疏散恐慌程度最终优化模型。结果表明,地铁应急疏散恐慌程度受年龄、携带行李情况、接受安全教育程度、相关事故灾害经历等人员个体因素,以及人员密度、疏散环境复杂程度、事故灾害发生位置等环境因素影响。应急疏散恐慌程度模型计算结果和应急疏散模拟试验结果相近。
