环境信息不对称对于循环经济的影响及其对策——兼谈环境信息服务业的发展与完善

指出循环经济背景下我国环境信息分布中的致命问题--环境信息的不对称分布,并指出不对称的表现,而后分析了环境信息对称对于循环经济的影响,在此基础上提出解决环境信息不对称的对策--发展环境信息服务业,并初步探讨了发展环境信息服务业的模式和步骤.     

美国离境外包经济动向的环境影响

最近美国离境外包经济发展很快，并引发继第一次产业革命（即工业革命）和第二次产业革命（即服务业超过制造业）之后的第三次产业革命，进而美国大批制造业向国外转移。这对我国承接制造业的产业转移是重大机遇，但同时也会遇到污染、能源转移的问题。建议我国抓住机遇，保持和发挥人力资源优势，迅速发展制造业，同时积极应对环境影响，分类管理，严格执法。

石油化工生产火灾隐患及预防对策

石油化工企业自身的生产、设备等特点决定了这类企业存在着一些特有的火灾隐患,这些隐患给安全生产带来了极大的威胁.因此,正确剖析和认识石油化工企业特有的火灾隐患,积极采取预防对策是石油化工企业安全工作的一项重要内容.     

工业化和城镇化进程中农民工问题的新探索

在工业化与城镇化大背景下,探讨我国农民工发展的特点和问题.首先从大中城市的利弊分析入手,探讨了小城镇发展的特点和存在的问题,分析发展小城镇是引导农民工合理流动的根本途径;然后从我国产业结构的现状分析,指出随着第三产业比例的增加尤其是服务韭的快速发展极大地推进了农村劳动力的转移,总结了产业结构合理化是加大农民工的就业力度的关键;进而从体制上探讨如何改革城乡的二元结构问题.总之,要解决农民工的问题,就要从根本上解决农民工在流动、就业、安置上的问题,这就应该从国家的体制方面、政策方面及人的观念上进行全面深入的思考.作为一个发展中国家,工业化和城镇化是农村劳动力转移的最终推动力量,工业化和城镇化的发展战略就是为了合理稳步地推进农村劳动力的转移.     

Uranium resource appraisal: Past trends and outlook for adequacy of supply

As uranium has practically no other industrial uses besides electricity generation, demand is determined by the requirements and stockpiling policies of electric utilities. The uranium market has experienced strong fluctuations and is currently affected by the reductions in nuclear forecasts resulting from the slowdown in electricity demand. Analysing supply/demand indicators proves, however, that in retrospect the development has been relatively smooth and it appears that oversupply is more a consequence of overly optimistic short-term expectations. In the future, especially in the long term, nuclear power policies continue to be concerned with striking a proper balance between increasing production capability and development of new reactor technologies which would be less dependent on the availability of uranium. A bounding scenario approach is applied in this article to the assessment of adequacy of supply under varying assumptions on the total installed nuclear capacity, available resource base and attainable production capability.     

Impacts of Chronic Anthropogenic Noise from Energy‐Sector Activity on Abundance of Songbirds in the Boreal Forest

Abstract: The effects of human activities in forests are often examined in the context of habitat conversion. Changes in habitat structure and composition are also associated with increases in the activity of people with vehicles and equipment, which results in increases in anthropogenic noise. Anthropogenic noise may reduce habitat quality for many species, particularly those that rely on acoustic signals for communication. We compared the density and occupancy rate of forest passerines close to versus far from noise‐generating compressor stations and noiseless well pads in the boreal forest of Alberta, Canada. Using distance‐based sampling, we found that areas near noiseless energy facilities had a total passerine density 1.5 times higher than areas near noise‐producing energy sites. The White‐throated Sparrow (Zonotrichia albicollis), Yellow‐rumped Warbler (Dendroica coronata), and Red‐eyed Vireo (Vireo olivaceus) were less dense in noisy areas. We used repeat sampling to estimate occupancy rate for 23 additional species. Seven had lower conditional or unconditional occupancy rates near noise‐generating facilities. One‐third of the species examined showed patterns that supported the hypothesis that abundance is influenced by anthropogenic noise. An additional 4 species responded negatively to edge effects. To mitigate existing noise impacts on birds would require approximately $175 million. The merits of such an effort relative to other reclamation actions are discussed. Nevertheless, given the $100 billion energy‐sector investment planned for the boreal forest in the next 10 years, including noise suppression technology at the outset of construction, makes noise mitigation a cost‐effective best‐management practice that might help conserve high‐quality habitat for boreal birds.

Emerging market patterns in the recycled paper trade

The international recovered paper trade serves two important functions: increasing raw material availability in the paper and board industry and providing economic incentives to recycle. The purpose of this paper is to shed further light on emerging patterns in this trade by empirically analysing the changes in the bilateral trade flows of recycled paper between 1992 and 2008. According to our estimations, two important changes occurred in the 1990s and 2000s. First, the growing importance of developing economies in global recycled paper trade plays a significant role in import demand as a determinant of trade flows. Second, the changes in global trade patterns necessitate investigating the transportation cost measures used in applied research.
