为研究通风对隧道内人员疏散的影响,引入通风作用力修正社会力模型,利用VS2010+Qt平台实现通风作用下隧道人员疏散速度模拟。结果表明:隧道人员疏散速度与通风风速、个体质量密切相关;通风风速增加,人员疏散速度降低且降幅逐渐增大;受个体表面积表达公式影响,个体质量对疏散速度影响以30 kg为界,当个体质量为20~30 kg时,疏散速度随个体质量增加而下降,且降幅逐渐增大;当个体质量为30~90 kg时,疏散速度随个体质量增加而上升,且上升幅度逐渐减小。研究结果为隧道通风及人员疏散方案制定提供参考依据。 相似文献

为探究道路交通事故因素和事故伤害的相关性,以2 467起涉及人员伤亡的交通事故为数据集,运用Apriori算法分别挖掘事故伤害关联规则,并结合社会网络分析的可视化和核心-边缘分析构建受伤事故和死亡事故的关联规则网络。结果表明:事故伤害程度与事故时间、道路条件和交通环境等因素关系紧密,尤其死亡事故与碰撞固定物、人行横道事故、高速公路、高速道路、非市区、酒驾和超速存在高相关性。基于树型贝叶斯网络(TAN)构建事故伤害程度的预测模型,预测结果准确率可达87.56%。 相似文献

The benefits of corporate social responsibility (CSR) affect the entire supply chains a firm participates in. However, not every firm is in a position to force the implementation of CSR in its supply chains as some, especially small and medium-sized enterprises (SMEs), lack the necessary power. Chain directors can implement it acting as a principal, whereas the other chain members can act as agents.In the principal-agent framework, two main problems occur due to information asymmetry: adverse selection and moral hazard. This paper examines how a code of conduct (i.e. Social Accountability 8000) can help address the principal-agent problem, for SMEs, between chain directors and partners. The research method involves four case studies on CSR practices as implemented by Italian and Dutch SMEs within their supply chains. 相似文献

21世纪是海洋世纪,这是国际社会的一个广泛共识。"海洋世纪"成为新世纪的代名词,在一定程度上揭示出海洋与人类社会的关系。环境社会学作为社会学的一个分支学科,基于社会学的方法、观点、理论,研究环境与人类社会之间的关系。本文从环境社会学的视角出发,总结"海洋世纪"提出的过程、原因及其特征,分析"海洋世纪"本身蕴含的环境社会学意义、"海洋世纪"提出的社会原因及社会影响。 相似文献

ABSTRACTThis article analyzes the emergence of a new environmental issue in the German press. Since the 1990s, scientists have detected traces of pharmaceuticals, hormones and chemicals in all segments of the water cycle. These micropollutants have negative effects on aquatic life and might affect human health. Their sources are manifold and include private households. Yet although micropollutants of are direct concern to media audiences, they are a challenging topic for news reporting. Although this issue is systemic and fraught with uncertainty, it does not easily translate into news stories. Our content analysis of 444 articles (1995–2015) reveals that the societal risk was rarely presented as a stand-alone topic. Instead, the issue was mostly covered as part of local routine reporting and framed as a challenge for experts to solve. Over time, the reporting became more managerial, while media framings of micropollutants gained more substance and scope. We contend that local routine reporting should receive more attention as a public forum for addressing emerging environmental concerns. 相似文献

ABSTRACTAs a discipline of crisis and care, environmental communication needs to address questions of environmental justice. This article argues that the most appropriate approach to studying environmental justice communication is engaged scholarship, in which academics collaborate with community partners, advocates, and others to conduct research. The article reviews prior engaged communication scholarship on environmental justice, and proposes four streams of future research, focused on news and information, deliberation and participation, campaigns and movements, and education and literacy. 相似文献

ABSTRACTUsing an integration of Norm Activation Theory, Value-Belief-Norm Theory and Narrative Persuasion, this study investigates the ability of an eco-dystopian science fiction film set in a world of excessive solar radiation to support intentions for pro-environmental behavior. Specifically, the influence of narrative engagement and explicit references to human responsibility for climate change are tested. A 2 (high vs. low narrative engagement) x?3 (human responsibility frame vs. temperature frame vs. no frame) plus control group (no film) experiment was conducted (n?=?257). Results show that compared to the control condition, the film had an indirect effect on behavioral intentions by raising the personal norm (a sense of personal obligation to act). The temperature change and human responsibility frames did not show any influence, while narrative engagement had an indirect effect on intentions by increasing guilt. The results are discussed with regard to their theoretical and practical implications. 相似文献
