Analysis of Local Acceptance of a Radioactive Waste Disposal Facility

Like many other countries in the world, Korea has struggled to site a facility for radioactive waste for almost 30 years because of the strong opposition from local residents. Finally, in 2005, Gyeongju was established as the first Korean site for a radioactive waste facility. The objectives of this research are to verify Gyeongju citizens' average level of risk perception of a radioactive waste disposal facility as compared to other risks, and to explore the best model for predicting respondents' acceptance level using variables related to cost-benefit, risk perception, and political process. For this purpose, a survey is conducted among Gyeongju residents, the results of which are as follows. First, the local residents' risk perception of an accident in a radioactive waste disposal facility is ranked seventh among a total of 13 risks, which implies that nuclear-related risk is not perceived very highly by Gyeongju residents; however, its characteristics are still somewhat negative. Second, the comparative regression analyses show that the cost-benefit and political process models are more suitable for explaining the respondents' level of acceptance than the risk perception model. This may be the result of the current economic depression in Gyeongju, residents' familiarity with the nuclear industry, or cultural characteristics of risk tolerance.     

试析西部地区环境权的特点

环境权作为一项基本人权得到了世界的普遍认同 ,一些国家通过立法将环境权确定为法定权利。环境权的客体是环境 ,这就决定了权利的质和量的区别。正因为如此 ,西部地区的环境权才呈现出自己的特点 :民族性 ,自然景观与恶劣的地理条件、丰富的自然资源与低生产能力并存 ,生存权对环境权行使的严重制约等。通过这些特点可以看到 :西部地区的根本问题是如何在解决生存权的过程中实现环境权 ,显然 ,这离不开其他地区的帮助。     

Accelerated Life Test Data Analysis for Repairable Systems

In this article, the imperfect maintenance model and proportional intensity model are used to analyze failure data of repairable systems in accelerated life testing. In the design and development phase of products, we should collect and analyze failure data quickly with small proto-type products. Thus, we test the products under accelerated conditions and if the products fail, then we repair and use those continuously in the life testing. Acceleration and repair models are needed to analyze the failure data. An age reduction model (Brown et al.'s Brown et al. 1983 Brown , J. F. , Mahoney , J. F. , Sivazlian , B. D. ( 1983 ). Hysteresis repair in discounted replacement problems . IIE Trans. 15 : 156 – 165 . [CSA] [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], model) and relationship between scale parameter and stress level are assumed. The stress acts multiplicatively on the baseline cumulative intensity. The maximum likelihood method is used, the log-likelihood function is derived, and a maximizing procedure is proposed. In simulation studies, we investigate the accuracy and trends of the maximum likelihood estimator.

Adaptive sampling for Bayesian geospatial models

Bayesian hierarchical modeling with Gaussian process random effects provides a popular approach for analyzing point-referenced spatial data. For large spatial data sets, however, generic posterior sampling is infeasible due to the extremely high computational burden in decomposing the spatial correlation matrix. In this paper, we propose an efficient algorithm—the adaptive griddy Gibbs (AGG) algorithm—to address the computational issues with large spatial data sets. The proposed algorithm dramatically reduces the computational complexity. We show theoretically that the proposed method can approximate the real posterior distribution accurately. The sufficient number of grid points for a required accuracy has also been derived. We compare the performance of AGG with that of the state-of-the-art methods in simulation studies. Finally, we apply AGG to spatially indexed data concerning building energy consumption.     

老的老小的小爱和微笑

在辽宁省绥中县,有这样一个群体,他们不分年龄、职业、学历、贫富,只为一个共同的理想走到一起,无论在抗震救灾的募捐现场,还是在福利院或养老院;抑或在街头清除城市“牛皮癣”的队伍中,还是在被捐助的贫困学生的家里,都能见到他们的身影.他们来去匆匆,不留姓名,但他们拥有一个共同的名字——爱心志愿者.     

中国制造业出口贸易隐含污染的测算及启示

基于投入产出法,以二氧化硫作为污染的代表性指标,测算2004—2010年中国制造业各部门的直接污染排放系数、完全污染排放系数及出口贸易隐含污染,利用结构分解法将隐含污染变化量分解为技术效应、结构效应和规模效应。2004—2008年,中国制造业出口贸易隐含污染占二氧化硫排放总量的一半以上,即超过一半的二氧化硫排放量是由贸易伙伴国的进口需求引起的。我国制造业各部门的直接污染排放系数和完全污染排放系数都有所下降,说明各部门的节能减排工作取得了较好效果。规模效应促使出口贸易隐含污染排放增加,技术效应促使制造业出口贸易隐含污染排放减少。未来,应当优化制造业产业结构,转变贸易增长方式;加强引导,实施绿色贸易政策;构建新的污染排放责任归属机制。     

审美教育的途径及其实践效应

审美教育是整个教育体系的重要组成部分 ,其地位和作用不可忽视。它主要是通过外在的 (即领域性、阶段性途径 )和内在的 (即情感教育途径 )两种审美途径 ,对人进行教育并产生积极影响 ,从而促进整个民族素质的不断提高。     

欧阳修俗艳词的人文意蕴

欧阳修创作的近70首俗艳词,千年来论者聚讼不已,或替欧公回护,指为伪作;或斥其亵浑,严加贬抑.然而俗艳词展现了欧阳修本人心灵世界的另一面,不但具有较高的历史真实性、可观的民俗意义和认识价值,还带起宋代一大批词人的竞相仿作,形成了贯串宋代、影响后世的“俗艳词现象”.俗艳词的本质在于倡言世俗生活的意义和挣脱封建礼教的禁锢,可视为宋代士大夫文字形式的“艳情生活录”和历史变革期中国的诗体<十日谈>.
