Public perception of air pollution sources across Europe

Air pollution is one of the primary concerns of our society for its effect on human health and the environment. Among the policy measures that can be put in place to limit air pollutant emissions, end-of-pipe technologies and/or regulatory instruments may be implemented through legislative acts. Also, equally important are behavioural measures, requiring citizens’ active involvement. The success of any measure to limit pollutant emissions requires the acceptance by the citizens that, in turn, implies a correct perception of the main pollutant emission drivers. We present here the comparison between the public perception of air pollution sources and the real-world situation through a survey carried out in seven European countries and involving 16 101 respondents. Our study shows a dramatic underestimation of the contribution of the agri-food sector to air pollution. This result is common to all respondents in the seven countries examined and only to a small extent depends on gender, age and socio-economic status of the respondents.     

土压平衡矩形顶管施工引起的地表沉降规律研究

为了分析与掌握矩形顶管施工引起的地表沉降变形规律，提出基于MIDAS-GTS有限元软件的分析方法，首先，通过工程实例验证MIDAS-GTS有限元软件在分析顶管施工引起地表沉降变形的有效性；其次，通过影响因素的敏感性分析确定不同影响因素作用下的地表沉降变形特性，这些影响因素主要包括开挖面支护压力、侧摩阻力、地层结构特性等；最后，通过地表沉降变形特性分析得出矩形顶管的适用范围。研究结果表明:基于MIDAS-GTS有限元软件的地表沉降规律分析方法和结果，可为矩形顶管施工过程提供相关参考和借鉴。     

基于环境卫星CCD数据的黄海浒苔遥感监测

2007年以来,黄海海域每年夏季都发生大面积浒苔绿藻潮,影响沿岸人民的生活、生产。考虑到其分布范围动则几千、上万平方公里,水面监测很难实施,尝试利用遥感技术对其分布和发展变化情况进行监测。基于中国自主产权的环境卫星(HJ1)数据,采用经典植被指数算法和人工辅助判读方法,对2013年黄海浒苔暴发全过程进行了连续遥感监测,分析了此次浒苔过程的分布和漂移路线。监测结果表明,浒苔绿藻潮首发于江苏盐城东部海域,由南向北逐渐漂移,面积逐渐扩大,结束于青岛东北部海域;该期间,浒苔最大覆盖面积达663.54平方公里。     

基于证据法学的环境监测原始记录设计

从证据法学概念的角度浅析了环境监测原始记录的证据范畴,根据其所属范畴的证据要求,归纳了环境监测原始记录的证据要求。结合实例,分析了环境监测原始记录存在的不足,并提出了改进建议。     

On the search for mimetic patterns in environmental disclosure: an international perspective

In this paper, we assert and test the proposition that environmental disclosure (ED) is structured by institutionalised myths and that is why ED is decoupled from environmental performance and media pressures. Focusing on firms from Canada, France and Germany, findings show that ED mimetic isomorphism for different topics varies among countries and by industry sensitiveness to the environment. The results corroborate the institutional presumption that institutionalised myths vary among different contexts. Our findings also suggest that institutionalised ED structures may not reflect environmental performance, mimetic patterns being affected by environmental performance. However, the decoupling between ED mimetic isomorphism and environmental performance decrease when firms’ ED credibility is questioned by the media.     

新形势下环境质量综合分析思路探讨

随着中国共产党第十九次全国代表大会的顺利召开,环保"大部制"改革、环境监测垂直管理制度改革以及国家"大气十条""水十条""土十条"的全面实施均对生态环境保护、环境监测乃至环境质量综合分析工作提出了新要求。新形势下,环境质量综合分析应与时俱进、开拓创新,进一步优化工作机制,加强系统分析,增强综合分析报告的科学性、规范性、时效性、精准性、客观性等,强化技术与能力支撑,更好发挥环境监测对环境管理和决策的引领作用。

Objectivity as Trained Judgment: How Environmental Reporters Pioneered Journalism for a “Post-truth” Era

Amid debate about the role and practices of journalism in the era of Presidents Trump and Putin, this commentary argues that environmental journalism offers a conceptual model and guide to action for all journalists in the “post-truth” or “post-fact” era. Since the specialism was formed in the 1960s, environmental journalists have reported on politically partisan issues where facts are contested, expertise is challenged, and uncertainty is heightened. To deal with these and other challenges, environmental journalism, this commentary argues, has reassessed and reconfigured the foundational journalistic concept of objectivity. The specialism has come to view objectivity as the implementation of a transparent method, as the pluralistic search for consensus, and, most importantly, as trained judgment. By developing these definitions through the reporting of several science policy controversies, environmental journalists have pioneered journalism for the “post-truth” era.
