生态文明建设的善治结构:三明治模型

在评析西方社会变革"三明治模型"的基础上,将其扩展应用于生态文明建设。借鉴西方社会变革的成功经验,基于我国实际构建生态文明建设的善治结构设计,构建了由生态政府、生态社会和生态公民协同至善的"三明治模型",并详细阐述了这一模型的动态演进过程和治理运行机制,为深化这一领域的研究提供了新视角和新思路。在生态文明建设的善治结构中,生态政府的重要职责是增强国家力量,生态企业发挥主责作用,生态公民的草根运动则是最广泛的基础。     

Conspicuous conservation: The Prius halo and willingness to pay for environmental bona fides

This paper develops a theory of conspicuous conservation, a phenomenon related to conspicuous consumption in which individuals seek status through displays of austerity amid growing concern about environmental protection. We identify a statistically and economically significant conspicuous conservation effect in vehicle purchase decisions and estimate a mean willingness to pay for the green signal provided by the distinctively designed Toyota Prius in the range of $430–4200 depending upon the owner's location. Results are related to the growing literature on green markets and suggest that policy should target less conspicuous conservation investments that will be under-provided relative to those that confer a status benefit.     

优良菌对原油降解性能的试验研究

以原油为唯一碳源,从长期被石油污染土壤的浸泡液中分离、筛选出2株降解原油的优良菌SY4和SY6,初步鉴定为: SY4和 SY6为芽孢杆菌属.通过降解性能实验的研究得出:2株菌对原油都有较强的降解能力,在摇床实验中,单一菌株在5 d后的原油降解率都高于60%,且2菌对原油的生物降解反应符合一级反应动力学特征.摇床实验和静态曝气实验都得出:SY6的降解能力比SY4强.通过本实验研究,为其实际应用提供一定的生物基础.
