仓面浇筑立体空间冲突致灾过程建模与伤害评价*

为定量评价大坝浇筑过程空间冲突致灾事故后果,通过对缆机运输典型情景进行危害能量运动分解,确定在水平和竖直方向运动方式,阐述危害能量在流动路径相互转化形式;根据能量守恒定律,分析危害能量在吊罐与承灾体碰撞接触之间转移规律,将吊罐与人头部接触过程抽象为带强阻尼的弹簧振子系统,建立危害能量与碰撞冲量相等的动量方程,量化空间冲突致灾后果。结果表明:吊罐坠落危害能量极大,产生的碰撞冲击力与吊罐的运输速度、高度呈正相关,与阻力系数呈负相关,风速、载重对其影响较大。对比2种不同碰撞情景发现,机械碰撞因顶部承载力缓冲,对人头部产生伤害远小于直接碰撞,并对碰撞结果分级评价,研究结果可为大坝浇筑交叉作业空间冲突致灾风险评价提供参考。

Implementing wildlife-management strategies into road infrastructure in southern Ontario: a critical success factors approach

Wildlife-road conflict has profound negative impacts on both wildlife populations and society. Despite a long-held understanding of this problem, in most regions the wildlife-management strategies (WMS) available to mitigate this conflict are still relatively underutilized. This study examines the implementation of these strategies into road infrastructure, using Southern Ontario as a case study, in order to develop an understanding of what leads to successful WMS implementation. The project management concept of critical success factors was applied and interviews with project decision-makers and key stakeholders were conducted. Nine factors were identified and a comparison between a ‘smooth’ and ‘rough’ project is used to illustrate the cumulative effects that these factors, and their interrelationships, have on project implementation success. Practitioners can use these findings to evaluate WMS projects based on likelihood of success and allocate resources accordingly, ultimately leading to increased chances of implementation and overall benefit to conservation and society.     

Sustainability Appraisal in neighbourhood planning in England

The preparation of strategic environmental assessment (SEA) inclusive sustainability appraisals (SAs) for neighbourhood plans (NPs) in England may be required when significant environmental effects are expected to arise from an NP. In this paper, we report on the result of a Ph.D. project, conducted between 2012 and 2015, in which all 15 NP SEA inclusive SAs that had been completed at the time were evaluated. In this context, the quality of SA practice was found to differ substantially. SAs were prepared either ‘in-house’ (i.e. by neighbourhood planning steering groups) or by consultants. The quality of SAs was found to be associated with their overall perceived degree of influence on the underlying NPs. Whilst the focus of this paper is on practice in England, findings are expected to be of interest to a wider international audience, in particular to those experimenting with voluntary neighbourhood/local level plan SA/SEA.     

When the dark ones become darker: How promotion focus moderates the effects of the dark triad on supervisor performance ratings

The current study adds to a growing body of research on dark personality traits by investigating the moderating role of promotion focus on the relationships among dark triad traits and facets of job performance. Specifically, we investigated the effects of the dark triad (i.e., Machiavellianism, narcissism, and psychopathy) on supervisor ratings of performance, and the moderating effect promotion focus has on those effects. Using field data, we surveyed 549 employees from a manufacturing company in the USA and obtained supervisor ratings of task performance and helping behavior for each employee. We found support for multiple hypotheses, which suggests that managers rated narcissistic and psychopathic employees as having poorer task performance and psychopathic employees as engaging in fewer helping behaviors than employees low in those traits. Furthermore, promotion focus strengthened these negative relationships. We did not find these effects for Machiavellianism. Implications of these findings for future dark personality research as well as the practical implications for managers and organizations are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

城陵矶综合枢纽工程建设对洞庭湖水动力影响模拟研究

受流域降雨量偏枯以及三峡工程蓄水运行等综合影响,洞庭湖季节性干旱问题近年来日益突出.为缓解洞庭湖旱情,湖南省和湖北省政府提出了建设城陵矶综合枢纽工程.枢纽工程的建设,将改变洞庭湖水动力特征,影响湖区生态环境.该研究基于MIKE 21模型构建了洞庭湖二维水动力模型,模拟预测了枢纽工程建设前后洞庭湖湖体水位、流速等水动力参数变化特征.验证结果显示:水动力模拟结果与实测值吻合较好,模型计算结果有效可靠.模拟结果显示:城陵矶综合枢纽调度运行后,能够有效抬升全湖水位0.78~1.06 m,增加湖泊面积5.96%~10.84%,增加湖容31.18%~39.69%.枢纽工程对缓解洞庭湖秋季旱情、春季旱情作用明显,能够在一定程度上解决洞庭湖枯水期提前、枯水期延长、枯季水位偏低等问题.随着水位的抬升,湖体流速有不同程度的减小,退水期、枯水期平均流速由0.30 m·s-1和0.23 m·s-1降至0.28m·s-1和0.19 m·s-1,分别降低了6.67%、17.39%.城陵矶综合枢纽运行后,水流速度减缓、水体滞留时间延长,将加大湖体富营养化风险.     

南水北调东线（江苏段）沿线污染物总量达标研究

基于江苏省2010年污染源普查资料和统计年鉴,选取化学需氧量（ COD）和氨氮（ NH4－N）为研究因子,统计南水北调东线江苏段污染物排放量并计算入输水干线污染物量;根据南水北调办治污工程规划,计算污染物削减量;根据2012年江苏省水环境功能区划,核定研究区域限排总量;结果污染物量COD、氨氮削减量分别为33114吨、2935吨,污染源结构中城镇生活源比例从23．34％降到9．10％,工业企业源比例从15．13％降到8．96％,污染源点源呈下降趋势,面源呈增长趋势,污染物入输水干线总量达到2015年限排总量要求。     

基于投影寻踪的资源环境综合绩效评估方法研究

资源环境综合绩效评估是建设节约型社会的一项基础工作.在传统的资源环境综合绩效指数中,各种资源消耗和污染物排放绩效的权重相等,导致综合评价结果的合理性受到影响.针对该问题,通过构建投影指标函数和采用遗传算法对投影方向进行优化,提出了基于投影寻踪的资源环境综合绩效评估方法,并应用于2007年中国各省、直辖市和自治区的资源环境绩效评估.研究结果表明,中国资源环境绩效水平空间差异明显,呈现东部高西部低的特征,因此必须合理调整西部地区的经济结构,提高资源利用效率和加强环境保护,实现可持续发展.该方法的权重取值较为客观和科学,评估结果合理,值得推广应用.
