澳大利亚新南威尔士州《污染土地管理法》及其实施效果

澳大利亚新南威尔士州1997年出台的《污染土地管理法》核心内容包括污染土地责任人的界定、初步调查令、重大污染土地的认定、治理令、自愿治理方案、继续治理令,以及污染土地治理费用的偿还,即环保署支付费用的偿还、公共权力机构执行命令时支付费用的偿还、当事人之间费用的偿还和统一基金拨款的偿还。《污染土地管理法》实施以来,效果较好。     

Examining the determinants of public environmental concern: Evidence from national public surveys

Early research showed that citizens’ environmental concern in the United States was linked to three individual-level factors: socio-demographic variables, political orientations, and personal beliefs or worldviews about human-nature relations. Given many changes in the American society over the last several decades, one important, yet unanswered question is whether these factors still drive public environmental concern in the United States today, and if so, to what extent. This study, drawing from extant theoretical and empirical studies, aims to reinvestigate the determinants of citizens’ environmental concern by employing three national public surveys conducted in 2004, 2007, and 2013. Our data analyses confirm and expand the findings of previous research on the significance and importance of political ideology, fundamental beliefs about human-nature relations, and certain socioeconomic factors such as gender and race in explaining citizens’ environmental concern. More specifically, political liberals, people with higher New Ecological Paradigm values, females, and Non-Whites tend to be more concerned about environmental problems than their counterparts are. Our data analyses also reveal some interesting findings when compared to many previous studies: first, our data indicate a positive relationship between age and environmental concern, suggesting that older people in the United States are more concerned about the environment than younger adults; second, unlike most past research showing a positive Education-Environmental Concern relationship, our study suggests that education level seems to have little effect in explaining citizens’ environmental concern measured in this study. Key implications for environmental policymaking and recommendations for future research are discussed in the conclusion.     

武夷新区土地利用变化及景观格局研究

以2010年的LandsatTM遥感影像图和武夷新区总体规划中新区2030年土地利用规划图为基础数据,在RS和GIS技术支持下,结合马尔科夫模型和景观生态学方法分析了未来武夷新区的土地利用与案观格局变化。结果表明：在规划实施后,建设用地通过占用耕地和林地而大面积增加,使得林地和耕地相应减少,人类活动对景观的干扰强度增大,区域景观斑块形状趋于规则简单化,斑块总数有所减少,平均斑块面积增大,景观连接度增强,破碎化程度降低,景观多样性增加。

平顶山矿区东、西分区特征关键影响因素研究

为研究平顶山矿区东西分区的特征,对比多种因素,分析矿区东西区的瓦斯分布特征、突出分布特征和构造煤分布规律,论述地应力和瓦斯耦合对东部矿区突出的控制作用。结果表明,东区瓦斯含量和突出强度明显高于西区,原因是其受控于东区褶皱区,地应力和瓦斯耦合控制着东区的突出;而锅底山断层的形成及其后期演化使西区突出危险性小于东区。东西地质构造的不同,不但导致构造煤、瓦斯含量分布不同,而且给地应力与瓦斯耦合提供了不同的条件。总之,东部褶皱区是造成东区与西区产生明显分区性差异的关键影响因素。     

Graduated driver licensing: the New Zealand experience

In New Zealand, on 1 August 1987, a three-stage graduated driver licensing (GDL) system that applied to all new drivers aged 15-24 years was introduced. The essential elements of GDL were a 6-month learner license (supervised driving) and an 18-month restricted license stage (with restrictions on night driving and carrying passengers). A blood alcohol limit of 0.03 mg% applied at both stages. EVALUATION STUDIES: Early studies indicated that young people were reasonably accepting of the restrictions, with the passenger restriction being the least acceptable. Problems of compliance with the restricted license driving restrictions were reported. Evaluations of the impact of the graduated driver licensing (GDL) on serious traffic-related injury showed that up until 1991-1992, an 8% reduction could be attributed to GDL. At this time, it was considered that reduced exposure was the main reason for this reduction. However, the number of fatalities and hospital admissions among young people continued to decline, as did the population rate and the rate per number of licensed drivers among the young driver age group. A further evaluation study showed that drivers with a restricted license had a smaller proportion of crashes at night, and with passengers, compared with drivers licensed before GDL. IMPACT OF GDL: These results suggested that GDL restrictions had contributed to the reduction in crashes among young people and that it was not simply a case of reduced exposure to risk. An update of the most recent crash statistics indicated that, compared with older age groups, the fatal and serious injury crash rate among young people has remained substantially below the pre-GDL level. This suggests that the impact of GDL has not diminished over time.     

New Zealand drivers study: developing a methodology for conducting a follow-up study of newly licensed drivers

PROBLEM: In recent years, there has been a significant reduction in traffic crash injury among young people, but they continue to be overrepresented in the traffic crash statistics. To improve this situation, sound scientific evidence is needed to develop effective policies and programs. METHOD: The aim of the proposed study is to provide this evidence by examining early driving and driving-related experiences of newly licensed drivers as they progress through the learner-, restricted-, and full-license stages of the graduated licensing system and to determine the impact of these experiences on subsequent negative traffic-related outcomes (risky driving behavior, injury traffic crashes, noninjury traffic crashes, infringements, convictions). Given the size and complexity of the proposed study, a comprehensive pilot study was undertaken to determine the feasibility of conducting a New Zealand-wide cohort study of newly licensed drivers. RESULTS: This article describes the pilot study process and the methodology that has been developed for the New Zealand-wide study.     

新时期消防工作发展思路

随着我国社会主义市场经济的发展和社会管理体制的变化 ,消防工作也面临着新形势。笔者认为 ,消防工作社会化是适应形势发展的必然要求 ,要在全社会建立起各级人民政府领导下的单位责任自负、隐患自除、风险自担 ,公安消防机构依法实施监督的消防社会化运行机制。新时期消防工作应通过以下方式实现社会化 :进一步完善消防法规体系 ;强化消防安全的基础性地位 ;加强宣传普及基本的消防知识 ;发展消防安全中介组织 ;建立消防安全评价制度和科学评价体系 ;依法实施消防监督     

Incidence of polybrominated diphenyl ethers in central air conditioner filter dust from a new office building

This study examined polybrominated diphenyl ethers (PBDEs) in central air conditioner filter (CACF) dust from a new office building in Shenzhen, China. Human exposure to PBDE via dust inhalation and ingestion were also estimated. PBDEs level in CACF dust was lower than those in the other countries and regions. Approximately 0.671 pg/kg bw/day PM_2.5 (Particulate Matter up to 2.5 μm in size) bounded Σ₁₅PBDEs can be inhaled deep into the lungs and 4.123 pg/kg bw/day PM₁₀ (Particulate Matter up to 10 μm in size) bounded Σ₁₅PBDEs tend to be deposited in the upper parts of the respiratory system. The average total intake of Σ₁₅PBDEs via dust inhalation and ingestion for adults reached ∼141 pg/kg bw/day in this building. This value was far below the reference dose (RfD) recommended by United States Environmental Protection Agency. Human exposure to PBDEs via dust inhalation and ingestion in the new building is less than the old ones.
