HUMAN BEHAVIOR AND RESPONSE TOWARDS STORM HAZARD IN WEST VANCOUVER,BRITISH COLUMBIA1

ABSTRACT: Human behavior and response towards storm hazard are examined in this study. One-hundred and twenty flood victims in West Vancouver, British Columbia, were administered a sentence completion test to ascertain how these victims behaved and responded to the flash flood of July 12, 1972. The sentence completion test consisted of 11 sentence stems. Seven of these dealt with the respondent's behavior toward the storm experience, and four with the issue of internal vs. external locus of control. Completions of the seven sentence stems at three time situations showed that West Vancouverites expressed the normal reactions of fear and anxiety before the storm; showed negative emotions during the storm; and displayed a feeling of mutual cooperation after the storm. Completions of the remaining four sentence stems revealed that West Vancouverites emphasized the importance of internal factors, viz., autonomy, drive and hard work, in controlling their lives. They recognized God as a benevolent - protective and almighty - powerful figure. Forty percent of the respondents did not believe in luck, while 8 percent regarded it as important in their lives. One might conclude that West Vancouverites could cope with natural hazardous threats better than those who rely on external factors in directing their lives.     

INTERNATIONAL DECADE ON DRINKING WATER AND SANITATION1

ABSTRACT: The UN conference on Human Settlements (HABITAT) held in June 1976 at Vancouver, Canada, concluded that nearly two-thirds of the population of the developing world lacked access to safe drinking water and that a larger proportion lacked the means for hygienic human waste disposal. The conference urged governments to give priority to these two areas in their developement process. In March 1977, the UN Water Conference, held at Mar del Plata, Argentina, called for establishing the 1980's as the Decade for Drinking Water and Sanitation. The goal would be to bring clean water and sanitation to all peoples in the world by 1990. Since March 1979, four separate UN bodies have passed resolutions supporting the Decade and calling on all governments to support the Decade's goals. The U.S. Government, other OECD member states, and the private sector must combine to make this Decade a success.

稀有鮈鲫外周血红细胞微核试验方法研究

将稀有鮈鲫(Gobiocypris rarus)半静态暴露于重铬酸钾溶液中,研究发现稀有鮈鲫的本底微核率处于较低的水平,重铬酸钾在不同浓度和时间暴露后能明显观察到外周血红细胞微核增加。在一定条件下存在剂量-效应关系和时间-效应关系,表明稀有鮈鲫可用于鱼类外周血红细胞微核试验。试验中每尾鱼观察15000个细胞,能有效地减小试验偏差,保证试验结果的可靠性。暴露浓度大于等于0.01mg/L时,染毒组与空白组的外周血红细胞微核率有显著性差异,其微核率随染毒时间的延长呈先升高后下降的趋势,均在24h时出现所有测定时间微核率的峰值。与其他鱼类比较显示,稀有鮈鲫具有较高的敏感性,可用于遗传毒物诱发微核的监测。     

Human Impacts on Drainages of the Mesa Central, Mexico, and Its Genetic Effects on an Endangered Fish, Zoogoneticus quitzeoensis

Abstract:  The Mesa Central of Mexico is of special conservation interest due to its high richness of freshwater fish species, of which the goodeines are one of the most representative groups. Through an integrated approach, we determined conservation priorities for goodeine populations. We based our recommendations on the genetic diversity (variation in five microsatellite DNA loci) in 10 populations of Zoogoneticus quitzeoensis and on an analysis of ecological (e.g., presence of exotic species), social (e.g., political situation), and environmental (e.g., pollution) information for 52 historical occurrence points for species in the genus Zoogoneticus . Patterns of genetic erosion and genetic diversity indices were closely associated with human impact. Recent bottleneck events were most evident in the populations from remnants of the lakes drained at the beginning of the twentieth century. We identified seven operational conservation units (OCUs), all of which should be conserved because they contain unique portions of the total variation of the species. Special attention needs to be given to increase genetic variability, recover population sizes, and reestablish contact among populations within OCUs. It is imperative to create an integrative and effective approach for the recovery and conservation of the freshwater fish diversity of Central Mexico that is based on social and natural sciences.     

商业区与轻轨站厅开口处防火分隔失效时人员安全疏散评估

针对相连接部位开口处的防火分隔失效时人员能否安全疏散进行评估,研讨人员安全疏散评估过程中所采用的定性分析和定量分析方法。以某商场与轻轨站相连接开口处为例,考察当防火分隔耐火性能失效后,商场内人员和轻轨站的人员能否从火灾中得以安全疏散;通过火灾模拟的方法,采用BuildEvac和FDS软件分别对火灾时人员疏散状况和火灾烟气的蔓延情况进行人员疏散模拟和火灾烟气运动模拟。根据模拟计算结果,对商场内人员和轻轨站人员的安全性进行详细分析和讨论,从而得出实例评估结论:当排烟系统正常工作时,即使防火分隔(防火卷帘)失效,火场环境对商业区和轻轨站的人员生命安全在整个疏散过程中均不会构成威胁,所有人员都能安全疏散到安全地点。     

煤矿安全生产中人的行为影响因子系统动力学(SD)仿真分析

在构建影响人的安全行为因素因果关系的基础上,运用系统动力学(SD)理论和方法,对影响人的安全行为关键因素进行动态预测,并通过仿真计算、对比分析安全投入增加对系统安全水平的影响。应用该方法建立的煤矿生产中人的安全行为指标水平模型,以求证安全投入与人的安全行为水平的相关性,为煤矿安全管理决策提供一种新的思路,亦有助于政府和煤矿企业科学地明确安全投入方向,降低人因事故率,提高煤矿生产的安全水平。     

航空维修人为差错影响因素分析中的模糊层次分析法

航空维修中的人为差错影响因素分析对于预防事故发生至关重要,如何定量分析及辨识出主要影响因素是亟待解决的问题。为此,结合航空维修实际,提出运用群组模糊层次分析法对人为差错影响因素进行量化排序和分类,归纳细化了影响因素层次体系,并给出了分析计算流程。以一起由维修人为差错所引发的航空事故为例进行了实证分析,结果表明:该方法能够辨识出航空维修中人为差错产生的主要影响因素,进而对制订最优事故预防方案,控制和减少该类事故的发生有积极意义。同时该方法对其他行业中的人为差错主要影响因素辨识有着一定的参考价值。
