青岛可持续发展战略下的环境经济评价

根据数据的全面性、准确性和可得性构建了青岛市可持续发展战略下的环境经济评价指标体系。运用经济发展(Ec)、环境污染(Ep)、环境质量(Eq)、生活水平(En)、人口发展(P)、社会发展(S)和资源消耗(Ru)等7项综合指数，对青岛市环境污染与资源利用现状进行分析，并对其与经济、社会和人口发展的关联性进行了评价，结果表明：青岛市社会、经济发展水平和人民生活水平不断提高，与其环境质量的逐年改善具有明显的对应关系，环境质量对经济发展的瓶颈制约作用越来越小；但社会、经济的发展造成资源消耗加快，经济发展对资源的依赖性逐年增强，说明青岛市的资源—经济—环境系统仍需调整；另外，除1996年环境对可持续发展造成较大压力外，1994——2000年青岛市资源消耗、环境污染对可持续发展造成的综合压力较小，说明其资源—环境—经济系统的持续发展能力比较强，子系统之间协调性较好。     

Connectedness, social support and internalising emotional and behavioural problems in adolescents displaced by the Chechen conflict

The study investigated factors associated with internalising emotional and behavioural problems among adolescents displaced during the most recent Chechen conflict. A cross-sectional survey (N=183) examined relationships between social support and connectedness with family, peers and community in relation to internalising problems. Levels of internalising were higher in displaced Chechen youth compared to published norms among non-referred youth in the United States and among Russian children not affected by conflict. Girls demonstrated higher problem scores compared to boys. Significant inverse correlations were observed between family, peer and community connectedness and internalising problems. In multivariate analyses, family connectedness was indicated as a significant predictor of internalising problems, independent of age, gender, housing status and other forms of support evaluated. Sub-analyses by gender indicated stronger protective relationships between family connectedness and internalising problems in boys. Results indicate that family connectedness is an important protective factor requiring further exploration by gender in war-affected adolescents.     

公共建筑环境下行人行为特性及拥挤机理研究综述

介绍国内外对于公共建筑环境下行人行为特性及拥挤机理方面的研究成果,主要包括:自由流情况下的行人运动速度,人群运动的最佳密度,行人的年龄、文化、性别、退让距离、温度、旅行目的、运动方向和建筑设施类型对行人流速度和流量的影响,以及行人流的密度和速度关系。成果显示:各国学者在人群的速度、密度和流量之间的相互关系方面研究较多,所得的结论趋于一致;但对于影响行人流速度和流量的各种因素并没有进行深入的研究,尤其是拥挤情况下行人的心理状态和拥挤事故的相互关系。     

Team mental models and their potential to improve teamwork and safety: A review and implications for future research in healthcare

The importance of team mental models (TMMs) - team members’ shared and organized understanding of relevant knowledge - for teamwork and team-performance, particularly in high-risk industries, has been recognized for almost two decades. In healthcare, however, systematic investigations on the influence of TMM on teamwork and team-performance had yet to be conducted at the time of this review, despite many authors considering the concept to be useful for medical teams. The lack of measurement procedures appropriate for settings as complex and dynamic as, for example, the operating room, represents a major obstacle for empirical research in healthcare. We systematically reviewed empirical studies on TMMs aiming to identify methods that could be applied in healthcare. In particular, we analyzed the methods used, and situations in which TMMs have been investigated. The reviewed studies were sorted according to task and team characteristics. We discuss the results of this review with regard to characteristics of healthcare teams including anaesthesia teams and teams of ward nurses. Each of these examples represents a distinct teamwork setting (e.g. long- vs. short-lived teams) and hence requires a different approach to TMM measurement (e.g. focus on task-model vs. focus on team-model). Implications for study design, feasible measurement approaches, and questions for future research on TMMs in healthcare are discussed. In sum, our findings highlight the possible significance of TMM research in healthcare and its potential benefits for team-performance and, ultimately, patient safety.     

Prenatal diagnosis in Coffin-Lowry syndrome demonstrates germinal mosaicism confirmed by mutation analysis

Coffin-Lowry syndrome is a rare X-linked, semi-dominant mental retardation syndrome resulting from mutations of the ribosomal S6 kinase 2 (RSK2) gene. In the present report, a male patient affected with Coffin-Lowry syndrome is shown to have a nonsense mutation of the RSK2 gene. His unaffected mother does not have this mutation in her lymphocytes. In her third pregnancy prenatal diagnosis by mutation analysis has detected gonadal mosaicism. As this is the second report of germinal mosaicism in Coffin-Lowry syndrome, the finding has important implication for genetic counselling. Copyright © 2001 John Wiley & Sons, Ltd.     

基于多模态信息融合的心理负荷评估*

为了相对稳定地识别人员是否处于心理负荷状态,设计并实施含能材料起爆作业心理负荷诱导试验。首先对心理负荷诱导情况进行判断,然后分别采集27名被试在静息状态和实施含能材料撞击起爆作业状态下的眼动、心率变异性（HRV）和脑电信号（EEG）,通过正态性检验和假设检验获得心理负荷表征指标并进行统计功效分析,依据表征指标,采用支持向量机（SVM）和随机森林（RF）算法建立多模态信息融合的心理负荷评估模型,最后采用被试工作特征曲线（ROC曲线）分析各模态组合和分类器的心理负荷识别性能。研究结果表明:双模态（眼动+EEG）下SVM算法和3模态下RF算法评估性能和稳健性较高,多模态信息组合具有优异的识别效果。     

我国石煤提钒废水的处理现状与展望

石煤提钒废水中含有大量的重金属、氨氮和盐类。介绍了石煤提钒中重金属废水、氨氮废水、高盐废水的处理技术,总结了各种废水处理技术在石煤提钒废水治理中的应用现状,并对石煤提钒废水的治理进行了展望。化学法应用广泛,但易造成二次污染;物理法具有广阔的应用前景,但处理效率低;生物法具有效率高、选择性强、废水处理成本低等优点,是一种极具发展潜力的废水治理方法,应加大在石煤提钒废水治理方面的研究。
