知识和经验对救援人员实战心理的影响分析

为了解影响救援人员实战心理的关键因素及其作用,采用走访、专家访谈和问卷调查的方法,对我国消防部队的人员组成、心理状况和实战心理进行调查和研究,重点分析消防队员掌握灾害知识和经验积累对实战中出现的恐惧、紧张、急躁等心理的影响。研究结果表明,灾害知识和救援经验的增加对大部分消防队员均能起到消除紧张情绪的作用,知识水平和实战中的紧张与恐惧心理呈现明显的负相关,且影响显著。笔者认为:将救援队伍和人员的灾害知识培训纳入日常工作,对提高救援部队的总体作战能力具有重要作用;对于高级指挥人员,理论知识水平的提高有助于更佳的指挥应对。     

饮食业油烟道火灾的模糊事件树分析

对饮食业油烟道火灾事故进行事件树分析时,历史数据的缺乏常常导致无法进行事件序列的定量计算.针对这一问题,利用专家对事故的模糊评判,引入模糊事件树进行定量计算研究.在模糊集理论的基础上,结合德尔菲法和判断矩阵法, 将模糊性语言转换为三角模糊数或梯形模糊数,应用模糊数截集以及模糊数清晰化方法,对后果事件发生概率进行计算.研究表明,饮食业油烟道火灾事故概率的模糊事件树分析是切实可行的,有助对饮食业油烟道火灾的认识、预防和扑救工作.

突发事件现场警戒区域的研究

阐述了事故危险区域、现场警戒区域的基本概念、设置目的和原则,提出将突发事故现场警戒区域分为三层,分别对应现场封锁线、警戒封锁线和交通封锁线,并就吸入毒性危害物质泄漏、燃气泄漏、建筑物火灾等事故,制定了具体的设置方法。现场警戒区域的设定,可在较小成本投入的前提下,通过采取积极的防范和应对措施,有效减少人员伤亡和财产损失,提高救援效率和效果。     

Arctic Tipping Points: Governance in Turbulent Times

Interacting forces of climate change and globalization are transforming the Arctic. Triggered by a non-linear shift in sea ice, this transformation has unleashed mounting interest in opportunities to exploit the region’s natural resources as well as growing concern about environmental, economic, and political issues associated with such efforts. This article addresses the implications of this transformation for governance, identifies limitations of existing arrangements, and explores changes needed to meet new demands. It advocates the development of an Arctic regime complex featuring flexibility across issues and adaptability over time along with an enhanced role for the Arctic Council both in conducting policy-relevant assessments and in promoting synergy in interactions among the elements of the emerging Arctic regime complex. The emphasis throughout is on maximizing the fit between the socioecological features of the Arctic and the character of the governance arrangements needed to steer the Arctic toward a sustainable future.     

Bioindication of volatile elements emission by the Puyehue-Cordón Caulle (North Patagonia) volcanic event in 2011

The emission of volatile pollutants from the volcanic eruption of the Puyehue-Cordón Caulle complex (North Patagonia Andean Range) that started in June 4th, 2011, was investigated by bioindication means with the epyphytic fruticose lichen Usnea sp. The elemental composition of pooled samples made up with 10 lichen thalli were analysed by Instrumental Neutron Activation Analysis. Eleven sampling sites were selected within the impacted region at different distance from the volcanic source. Five sites were selected as they were already sampled in a previous study prior to the eruption. Two other new sampling sites were selected from outside the impacted zone to provide non-impacted baseline sites.The elements associated with the lichen incorporation of particulate matter (PM) of geological origin were identified by linear correlation with a geochemical tracer (Sm concentrations). The elements associated with PM uptake were Ce, Eu, Fe, Hf, La, Lu, Na, Nd, Sb, Sc, Se, Ta, Tb, Th, U, and Yb. Arsenic and Cs concentrations showed contributions exceeding the PM fraction in sites near the volcanic centre, also higher than the baseline concentrations, which could be associated with permanent emissions from the geothermal system of the Puyehue-Cordón Caulle complex. The lichen concentrations of Ba, Ca, Co, Hg, K, Rb, Sr, and Zn were not associated with the PM, not showing higher concentrations in the sites nearby the volcanic source or respect to the baseline values either. Therefore, there is no indication of the emission of volatile forms of these elements in the lichen records. The lichen records only identified Br volatile emissions associated with the Puyehue-Cordón Caulle complex eruption in 2011.     

A paradigm of an integrated transboundary environmental education,training, and technology transfer project

The Rodopi mountain range is located between Greece and Bulgaria and constitutes a natural and political boundary whose crest delimits the frontier between the two countries. However, these two neighboring countries have significant differences: Greece is one of the oldest members of the European Union (EU) while Bulgaria has just recently entered the European family. As a result, the existing financial and political differences between the two nations are also reflected in issues concerning the environmental know-how, education, and training, since Greece seems to have a small lead in these fields. On the other hand, given that Bulgaria possesses exceptional scientific personnel, it has made significant progress in all aspects of environmental policy during the last decade by absorbing up-to-date knowledge and putting it into practice; thus, catching up with the other EU countries in environmental issues is just a matter of time. Taking these factors into account, the Department of Forestry and Natural Environment Management of the Technological Educational Institute of Kavala (Greece) and the Department of Geography-Ecology and Natural History (Bulgaria) prepared a joint proposal which was approved and financed by the European Union Initiative ΙNTERREG IIIΑ/PHARE CBC GREECE-BULGARIA. The proposal concerns the Rodopi mountains and focuses on integrated environmental education, technology exchange, and transfer between the two institutions. The Rodopi complex constitutes a very important ecosystem of particular ecological and biological interest for both countries. This paper reveals the cooperation possibilities on environmental education and know-how exchange with regard to the shared natural resources of these contiguous countries.
