工频电磁场对公众健康及风险感受影响调查

为调查工频电磁场对附近居民健康及风险感受的影响,对16条已投运110~500kV输电线两侧居民(n=615)开展问卷调查,根据输电线运行参数计算工频电磁场相对曝露强度,分析了工频电磁场对距线路中心50m内、外受调查者产生的健康影响差异,以及不同工频电磁场曝露强度、电压等级、塔型附近受调查者风险感受和负面情绪的均值差异,并通过多元线性逐步回归分析分别建立了工频电磁场公众风险感受、负面情绪与影响因素之间的最优回归模型.结果表明,工频电磁场对50m内和50m外受调查者产生健康影响的相对风险值为0.87;在本次调查的工频电磁场范围内(E<0.35kV/m,B<0.80 μT),公众风险感受和负面情绪受工频电磁场曝露强度影响很小,受输电线架线塔外观大小、塔型、既有身体状况等因素影响显著.

Characterizing Spatial Uncertainty when Integrating Social Data in Conservation Planning

Recent conservation planning studies have presented approaches for integrating spatially referenced social (SRS) data with a view to improving the feasibility of conservation action. We reviewed the growing conservation literature on SRS data, focusing on elicited or stated preferences derived through social survey methods such as choice experiments and public participation geographic information systems. Elicited SRS data includes the spatial distribution of willingness to sell, willingness to pay, willingness to act, and assessments of social and cultural values. We developed a typology for assessing elicited SRS data uncertainty which describes how social survey uncertainty propagates when projected spatially and the importance of accounting for spatial uncertainty such as scale effects and data quality. These uncertainties will propagate when elicited SRS data is integrated with biophysical data for conservation planning and may have important consequences for assessing the feasibility of conservation actions. To explore this issue further, we conducted a systematic review of the elicited SRS data literature. We found that social survey uncertainty was commonly tested for, but that these uncertainties were ignored when projected spatially. Based on these results we developed a framework which will help researchers and practitioners estimate social survey uncertainty and use these quantitative estimates to systematically address uncertainty within an analysis. This is important when using SRS data in conservation applications because decisions need to be made irrespective of data quality and well characterized uncertainty can be incorporated into decision theoretic approaches.     

城市重大危险源区域风险评价方法研究

针对城市应急管理的特点,提出了一种城市重大危险源区域风险评价方法。在ARAMIS方法的基础上,对严重度计算进行了修订,引入了急性暴露指南（AEGL）标准对事故后果进行分区;同时,增加了与应急救援效率相关的指标进行风险目标的脆弱性评估;利用GIS技术,对严重度和脆弱性进行叠加分析,绘制出城市重大危险源区域风险地图。以液氨储罐毒气泄漏事故为例,对文中提出的方法进行了验证。实例分析表明,此方法为快速获取城市重大危险源区域风险的空间分布格局提供了新思路,对于降低城市突发环境污染事故的影响和辅助决策者制定科学的城市公共安全管理决策具有一定的现实意义。     

基于群组决策和模糊层次分析法的城市公共安全评价

为科学地评估城市公共安全现状,根据我国城市公共安全的特点及国家城市安全规划的相关要求,从能力和脆弱性两方面构建了多层次多指标的城市公共安全评价指标体系。通过群组决策和模糊层次分析法,针对不同的指标考虑专家的个体权威和专家群体意见的一致性,引入综合重要度将专家个体判断矩阵集结成群体关于指标权重的判断矩阵,通过群体判断矩阵计算各评价指标的权重。最后根据可拓学理论构建多级可拓评价模型对某市公共安全灾害要素子系统进行评价,得出其安全状况属较安全等级,同时也证明该方法在城市公共安全评价中有较好的适用性。     

我国政府应急管理日常机构的设置模式与制度架构

应急管理日常机构既负责政府应急管理的日常事务,又负责政府应急响应中的具体协调。当前,我国各级政府的应急办存在着权力过小、层级过低、能力有限、和其他机构职权冲突等问题,将其简单扩充、升级又会导致新问题,需要加以改革。在应急管理日常机构的各种代表性设置模式中,美国的FEMA值得借鉴。我国政府应当组建一个综合性的应急管理部门,整合部分职能单一的应急机构,并对其他履行应急管理职能的部门行使协调权,同时承担政府应急办公机构的职能。     

Mountain environment and population in Georgia: case study of Upper Svaneti

The purpose of the presented research is to identify local community opinions toward ecological problems in one of the mountainous region of Georgia (Upper Svaneti), to analyze how population ‘perceive, experience, and interpret’ the social, and ecological issues.

The paper is based on the results of Upper Svanet ipopulation’s survey which was carried out by the authors of presented paper during the August of 2015 and 2016.The questionnaire was elaborated taking into account the peculiarities of the region. Stratified-cluster selection method was used for selection of respondents and database compilation. For statistical analysis of polling data the SPSS package was used.

Based on the statistical analysis of survey results, the following issues have been studied: the most important ecological problems, environmental problems with respect to socio-economic ones, information sources on ecological problems, people’s trust in environmental issues, awareness level of the population on environmental policy, their personal contribution in environmental protection, ways to solve ecological problems, implemented environmental measures.

The obtained results are important to foster mountain population’s active participation in processes that contribute to decision-making processes, planning and implementing programs for sustainable development.     

Ethnicity,income, and disaster preparedness in Deep South Texas,United States

This paper examines the influence of a series of demographic and socioeconomic factors on preparedness outcomes for a sample of residents of the Rio Grande Valley in the southernmost part of Texas, United States. Data were collected as part of the regional Pulse of the Valley Study, a general social survey of south Texas residents conducted by the Center for Survey Research at the University of Texas‐Rio Grande Valley. The purpose of this investigation is to understand better the effects of ethnicity and income on preparedness within a region of the US that suffers from widespread poverty and limited infrastructure and is prone to flooding and hurricanes. Taken together, the results suggest that while age, disaster experience, and income are associated with preparedness, the relationship between preparedness and ethnicity remains complex. Furthermore, policymakers should consider initiatives that address the socioeconomic and other issues that shape preparedness for a disaster.     

双出口疏散吸引区域模型建立与模拟分析

为研究建筑体内人员疏散的出口选择行为,提出基于元胞自动机的人员疏散模型。以学校常见的双出口教室为例进行研究,建立双出口疏散吸引区域模型,得出人员密度较低和较高时疏散吸引区域边界的函数表达式,指出人员密度较高时,边界函数基本满足边界到出口距离的平方之比等于出口的宽度之比;通过对出口宽度、人员数量和出口位置等参量进行仿真分析,充分验证了提出的双出口疏散吸引区域模型的合理性;研究结果有助于合理分配疏散人员,充分发挥建筑疏散的潜在能力。     

Environmental Education: Biodiversity

Environmental education was a principal topic on the agenda of the Stockholm 1972 Conference. In response to its recommendation UNESCO and UNEP developed and launched the International Environmental Education Program (IEEP) in 1977. Environmental education was perceived to encompass in-school and out-of-school activities and public awareness. Later developments added training to its objectives and the concept of sustainable development to its dimensions. The international Convention on Biological Diversity (CBD) represented a phase in the world commitment to conservation of nature. It underpinned biodiversity in the fields of environmental education. Biodiversity education is based on five pivots: scale of boundaries (from local to worldwide), perspectives, goals, themes (vary according to actors), and assimilation (evaluation of programs of action). Directions relate to learners and teachers, and processes address: awareness, school education, education (and professional training) at tertiary level, roles of communication and media institutions.
