日军在侵华战争期间,无视国际公约(法),在战场上频频使用化学武器,致使众多中国军民伤亡。大量史事证明,在1943年11月初至12月底的中日常德会战中,由于日本华中派遣军在作战中多次实施毒气(弹)攻击,致使中国第六、第九战区的参战部队伤亡惨重。此战中“日军使用毒气次数之多,为抗战以来所仅见”。 相似文献

Who Holds the Stakes? A Case Study of Stakeholder Identification at Two Nuclear Weapons Production Sites 总被引:1,自引:0,他引:1

Traditional risk assessments, including those involving the United States Department of Energy (USDOE), are often criticized for producing useless or noncredible management responses because they did not meaningfully involve the public. The first step to involve the public is to identify appropriate active participants (stakeholders). This study was done to understand the processes used to identify stakeholders to serve on advisory boards established at the two largest remediation sites in the United States: the Hanford Nuclear Reservation in Washington state and the Savannah River Site in South Carolina. The Hanford stakeholder identification process produced an interest-based board whereas the Savannah River Site strategy produced population-based representation. The basic goals of the stakeholder advisory groups were similar. However, different processes were used to identify the participants for the groups in part because of distinctly different social and cultural conditions in the areas affected by the operations of the two facilities, and in part because of the different level of trust of the USDOE and their contractors at Hanford compared with Savannah River. The discussion analyzes their different needs and potential for successful citizen participation. 相似文献

Methods for assessing the variability of an estimated contour of a density are discussed. A new method called the coverage plot is proposed. Techniques including sectioning and bootstrap techniques are compared for a particular problem which arises in Monte Carlo simulation approaches to estimating the spatial distribution of risk in the operation of weapons firing ranges. It is found that, for computational reasons, the sectioning procedure outperforms the bootstrap for this problem. The roles of bias and sample size are also seen in the examples shown. 相似文献

虎式坦克是第二次世界大战期间纳粹德国装备的一种重型坦克。作为战争期间投入使用的一种新式武器,德军对虎式坦克给予了极大的期望。与纳粹在战争中使用的众多新式武器一样,虎式坦克未能帮助德军扭转战局,但是,这种坦克却为我们评价二战期间的新式武器提供了最佳标尺。 相似文献

The regional economic impacts of the U.S. Department of Energy's accelerated environmental cleanup plan are estimated for the major nuclear weapons sites in Colorado, Idaho, New Mexico, South Carolina, Tennessee, and Washington. The analysis shows that the impact falls heavily on the three relatively rural regions around the Savannah River (SC), Hanford (WA), and Idaho National Engineering and Environmental Laboratory (ID) sites. A less aggressive phase-down of environmental management funds and separate funds to invest in education and infrastructure in the regions helps buffer the impacts on jobs, personal income, and gross regional product. Policy options open to the federal and state and local governments are discussed. 相似文献

20世纪 5 0年代美国“大规模报复战略”出台的成因首先是时代的产物 ,即冷战的产物 ;其次 ,它是由战后美国两党斗争、麦卡锡主义等诸多政治因素的压力促成 ;再次 ,也是战后美国经济发展中经济波动压力的结果 ;最后 ,美国核武器及运载系统等方面军事技术的领先 ,是其出台的技术基础。 相似文献

Based on experience gained while serving a public oversight commission appointed by the governor of Colorado, hazard management at the Department of Energy's Rocky Flats nuclear weapons plant is reviewed. Specific reference is made to the plant's history of controversy, its defense-in-depth strategy of hazard control, occupational health issues, public exposure to plutonium, and the assessment of low-probability, high-consequence risks. This leads to the conclusion that Rocky Flats is, by any objective standard, a hazard management success. It follows that public distrust of Rocky Flats arises as much from fear and loathing of nuclear weapons themselves as from the manufacturing process by which they are made. 相似文献
