The nuclear disaster management system in Taiwan: a case study of the third (Maanshan) nuclear power plant

This paper explores the effectiveness of the nuclear disaster management system in Taiwan via a review of the third (Maanshan) nuclear power plant. In doing so, the Fukushima Daiichi nuclear disaster in Japan on 11 March 2011 is reviewed and compared with the situation in Taiwan. The latter's nuclear disaster management system is examined with respect to three key variables: information; mobilisation; and inter‐organisational cooperation. In‐depth interviews with 10 policy stakeholders with different backgrounds serve as the research method. The results point up the need for improvement in all dimensions. In addition, they highlight three principal problems with the nuclear disaster management system: (i) it might not be possible to provide first‐hand nuclear disaster information immediately to the communities surrounding the Maanshan facility in Pingtung County, southern Taiwan; (ii) the availability of medical resources for treating radiation in Hengchun Township is limited; and (iii) the inter‐organisational relationships for addressing nuclear disasters need to be strengthened. Hence, cooperation among related organisations is necessary.     

乡村振兴背景下县域农业农村创新发展评价及空间格局——以甘肃省为例

实施农业农村现代化创新发展措施,将有效促使乡村振兴战略长远推进,形成我国农业农村创新发展的新局面。基于甘肃省86个县域研究单元,从创新投入、创新保障、创新效果三个维度构建了包含28个二级指标的农业农村创新发展评价指标体系,就农村地区创新发展水平进行综合评价。结果表明：（1）甘肃省农业农村整体创新发展得分呈上升趋势,但增长幅度较为缓慢。综合创新能力得分较高的县（区）主要集中在河西地区东部,得分较低的县（区）主要集中在南部民族地区。河西地区创新保障和创新效果水平处于全省前列,南部民族地区创新投入水平较低。（2）全省农业农村创新发展在东西方向上表现为西高东低,2013年以后逐渐表现出“两头高、中间低”趋势;在南北方向上表现北高南低;在东南—西北方向上呈现出西北高、东南低;在西南—东北方向上呈现出东北高、西南低。创新发展指数方向特征未发生明显变化,在空间上具有一定的锁定性。（3）创新发展热点区域集中在河西地区张掖市、武威市及金昌市,冷点区域集中分布在南部民族地区;极冷点区和极热点区数量减少,县域农业农村创新发展差距在减小。（4）多元资本投入、农业经济发展、自然地理条件及资源禀赋、农业基础设施配置、农业发展政策等通过内外因素结合创新发展供需两侧作用于甘肃省农业农村创新发展时空演化。     

退牧还草地区生态补偿机制研究

退牧还草工程作为21世纪初国家启动的一项重大的生态治理工程。在部分地区已取得了初步成效。然而也暴露出了不少问题。尤其是现行的补偿体系不够完善。无法实现农牧民的适度补偿。因此。建立与完善退牧还草项目的补偿体系。对巩固草原地区生态建设成果意义重大。本项研究在构建完整的生态补偿机制分析框架的基础上。通过问卷调查及跟踪访谈等方法。对内蒙古翁牛特旗退牧还草项目的实施进行实证分析。并根据不同类型草场的产量与承载力。遵循“以失定补”的原则。制定了不同类型草场的补偿标准。最后提出建立与完善退牧还草地区生态补偿机制的途径与措施。     

表没食子儿茶素没食子酸酯对四氯苯醌细胞毒性的保护作用研究

四氯苯醌(TCBQ)是高毒致癌化合物,而表没食子儿茶素没食子酸酯(EGCG)是茶叶中主要的茶多酚活性成分.利用人肝癌细胞系HepG2细胞,通过细胞存活率MTT毒性实验,探讨EGCG是否能解除TCBQ的毒性作用.实验结果表明,低浓度(5～40 μmol· L-1)的EGCG对TCBQ(200μmol·L-1)导致的细胞毒性有一定的缓解作用.此保护与EGCG和TCBQ之间的直接相互作用有关,紫外吸收光谱及高效液相色谱分析的实验结果表明EGCG降低TCBQ毒性的原因可能是其促使TCBQ还原为四氯氢醌TCHQ,并延缓了TCHQ的自氧化过程.     

An overview of the environmental finance policies in China: retrofitting an integrated mechanism for environmental management

Considering the significant roles of the policies in developing environmental finance, an overview is conducted on the environmental finance policies （EFPs） in China. This paper analyzed the definition, scope, evolution and main instruments of EFPs. The implementation progress of financial activities on each instrument are investigated respectively. Then the experiences learned from and failures discovered in the development of the EFPs are discussed well recommendations for further improvement of the EFPs and their implementation are provided. Our study found that the EFPs have been established in China after a four-phase evolution since the early 1980s. The policies have played a critical role in leading to a rapid development in environmental finance by involving more financial instruments to accomplish the objective-led environmental plans. Driven by the policies, the new green credit （GC）, green security （GS）, and green insurance （GI） instruments have been phased in as supplements to the conventional command and control approaches to improve the environmental governance of financial activities and pollution sources. However, the market mechanism of financial institution is limited due to their defensive and incapable performance on implementation some of EFP instruments. To further strengthen the effectiveness of EFPs in facilitating environmental man- agement, recommendations are made mainly on the aspects including developing more specific policy guidelines, enhancing information sharing and disclosure, providing sufficient economic incentives, establishing environmental liabilities with financial activities, and involving issues related to climate change, and biodiversity and ecosystem service.     

Occupational injury and accident research: A comprehensive review

In this paper, a comprehensive review of the concepts of occupational injury and accident causation and prevention is presented. Starting with hazard identification, the issues on risk assessment, accident causation, and intervention strategies are discussed progressively. The distinctiveness and overlaps in accident and injury research are highlighted. Both empirical research in terms of hypotheses tested and theoretical research such as accident causation models are compared and contrasted. Finally, based on the critical appraisal of the comprehensive review, future research directions on occupational injury research are delineated.

基于SEM的建筑企业安全文化绩效形成机制研究

为探讨工程项目情境下建筑企业安全文化构成及其形成绩效机制,基于扎根理论,提出安全文化包含物质、制度、观念及情境4部分,依此构建其与安全绩效因果关系的结构方程模型(SEM),运用软件AMOS7.0对问卷调查所得数据进行分析并对模型进行验证。结果表明,安全情境文化对安全结果产生持续、微弱的负向影响;安全观念文化对安全结果产生较大间接影响;而安全制度文化和物质文化对安全结果的影响都有直接和间接影响(通过影响安全行为最终影响结果)2方面,并据此提出持续改进情境文化、综合采用行为管理方法与非行为管理方法的建议。     

电石渣处理洗煤废水的效果及作用机理研究

为了防止洗煤废水的污染并使之处理后能够回用,开展了电石渣-PAM(聚丙烯酰胺)处理洗煤废水小试实验研究以及实际工程应用的研究,并通过实验与理论分析,对电石渣处理洗煤废水的作用机理进行研究.实验研究结果以及实际工程应用效果表明,采用电石渣-PAM混凝沉淀法处理洗煤废水具有较好的处理效果,处理后煤泥水的各项指标均能达到国家排放标准,且能满足洗煤工艺的用水要求.实验研究与理论分析结果表明,电石渣对洗煤废水的混凝作用不是补给了OH-,而是提供了大量的Ca2 ,Ca2 通过压缩双电层,破坏了煤泥颗粒的稳定性,从而使煤泥颗粒发生凝聚,OH-和Ca(OH)2对洗煤废水的混凝不直接起作用.
