The science of corporate social responsibility (CSR): Contamination and conflict in a mining project in the southern Ecuadorian Andes

In this article, I explain the role that scientific studies play in shaping collaboration and conflict over mining exploration in the Ecuadorian highlands. Toronto-based IAMGOLD conducted water quality studies to simultaneously fulfill legal obligations and secure support for drilling in an environmentally sensitive zone. With these studies, IAMGOLD generated collaborative relations with local authorities and university scientists. However, water quality studies were also used by dairy farmers to establish new connections for an opposition movement. The scientific studies enabled IAMGOLD and the dairy farmers to make competing claims about the responsibility for contamination of an important watershed. This article analyzes the conflict that resulted and challenges conventional wisdom that distinguishes a corporation's legal obligations from its voluntary CSR programs.     

Volunteer Macroinvertebrate Monitoring: Tensions Among Group Goals,Data Quality,and Outcomes

Volunteer monitoring of natural resources is promoted for its ability to increase public awareness, to provide valuable knowledge, and to encourage policy change that promotes ecosystem health. We used the case of volunteer macroinvertebrate monitoring (VMM) in streams to investigate whether the quality of data collected is correlated with data use and organizers' perception of whether they have achieved these outcomes. We examined the relation between site and group characteristics, data quality, data use, and perceived outcomes (education, social capital, and policy change). We found that group size and the degree to which citizen groups perform tasks on their own (rather than aided by professionals) positively correlated with the quality of data collected. Group size and number of years monitoring positively influenced whether a group used their data. While one might expect that groups committed to collecting good-quality data would be more likely to use it, there was no relation between data quality and data use, and no relation between data quality and perceived outcomes. More data use was, however, correlated with a group's feeling of connection to a network of engaged citizens and professionals. While VMM may hold promise for bringing citizens and scientists together to work on joint conservation agendas, our data illustrate that data quality does not correlate with a volunteer group's desire to use their data to promote regulatory change. Therefore, we encourage scientists and citizens alike to recognize this potential disconnect and strive to be explicit about the role of data in conservation efforts.

人群疏散行为仿真技术研究

提出并建立了一种人群疏散仿真模型。针对疏散空间中障碍物的动态布局,采用网格法获得各障碍物包围盒坐标,依据最短路径原则采用几何法确定每个个体起始疏散路径,解决了人群疏散的空间连续性问题。针对人群疏散时个体之间的差异性,依据个体与个体之间的作用力、摩擦力动态改变个体的行进方向,以及依据人群密度采用人群疏散速度模型实时确定每个个体的运动速度,解决了个体之间的动态避碰、绕行和超越等问题。针对人群疏散时多个出口的选择问题,提出了把出口拥挤状态与个体心理慌乱状态相结合的出口选择方法。最后采用粒子系统实现了上述人群疏散行为的二维仿真并取得了较好的效果。     

基于社会科学统计程序(SPSS)回归性分析的尾矿库事故预测模型

基于社会科学统计程序(SPSS)软件的分析功能,对调查研究中获取的尾矿库案例进行数据提炼和分类编码,找出相关因子并进行回归性分析。最终目的是找出尾矿库各个因素的内在联系,建立简单的尾矿库事故模型,从而可以初步预测尾矿库事故发生的可能性。该预测模型为尾矿库事故的研究提出了新方法,对于防灾减灾以及保护人民生命财产安全起到了积极作用。     

吴淞工业区大气降尘变化规律及趋势

吴淞工业区是重工业聚集区,烟(粉)尘的排放量非常大,造成该地区空气污染严重.为了解降尘的污染特征、变化规律及趋势,以近10 a监测数据为依据,运用方差分析等数理统计方法对工业区降尘量进行分析,检验不同季节降尘的差异并简要分析原因,使用秩相关系数法对其进行趋势分析.结果表明,工业区降尘量较混合区与清洁区明显不同; 工业区与混合区的降尘受本地源的影响较大,4季的降尘量没有明显差异,相反清洁区的4季降尘呈显著差异.10 a来工业区及其周边地区的降尘量下降了56%,说明环境综合整治取得了显著效果,使区域环境空气质量得到改善.     

飞行安全的针对性评估

根据飞行员执行新的或特殊任务的需要,在研制飞行安全评估系统时,设置了针对性评估模块.运用层析分析法(AHP)确定了针对性评估模块与一般性评估模块的权重关系.根据飞行安全理论确定了一般性评估简捷方法的因素、要素及量化数据;根据层析分析法、基元事件分析法确定了针对性评估模块的结构和因素的权重,采用基元事件分析法、飞行法规分析和调查研究相结合的方法,对针对性评估的要素进行了量化.最后针对具体事例做了评估计算.研究表明,当针对性评估的安全度小于90%时,应引起足够的警觉,采取必要的措施.     

结构分析中模拟与仿真技术研究

由于像洪水、水灾、地震这样一类自然灾害的原型重复试验几乎是不可能的,因此计算机仿真技术在这一领域的应用具有重要的意义。本文探索了土木工程中模拟与仿真的概念、特征及实现途径,阐述了关于仿真智能化、可视化的技术细节及仿真的基本思路;结合面向对象程序设计（OOP）概念,提出了结构分析程序设计的原则及标准。在此基础上,编写了基于Windows的结构有限元分析软件SmartSEA.
