重构煤炭主体专业教育的公益性

从煤炭主体专业教育具有的公益性属性分析入手,指出煤炭主体专业的办学经费日紧和煤炭主体专业边缘化与去煤化,公益性日渐式微。建议从国家、高校、企业、个人家庭等各个层次全方位重构煤炭主体专业教育的公益性,加强国家利益至上,强化政府主渠道作用,在政策与教育投入要向其倾斜,优先发展与保障煤炭主体专业的教育,制定相关法规确保煤炭专业生源与人才培养质量,并在该领域就业。国家、企业、高校与个人家庭利益相关者都应在制度上强化各自应有的责任,从而形成一个多层次全方位良性互动发展的培养与吸纳人才的机制,确保煤炭主体专业教育的公益性,促进煤炭主体专业健康发展,满足安全生产的人才需求的供给,从而为煤炭安全生产提供重要保障。

Public Participation and Effective Water Governance at the Local Level: A Case Study from a Small Under-Developed Area in Chile

The concept of participation in rural development has been evolutionary for the past two decades with those involved, such as development agencies and governments, particularly in rural water supply, re-evaluating their active role. The move towards effective community participation has encouraged a shift from the traditional top-down to a bottom-up approach whereby there is a decentralisation of unevenly distributed resources and power to empower a community and allow mobility of ‘people participation’. The Molinos water project is the first large-scale development project of its kind introduced into the village of Molinos in an under-developed area of Chile, where there has been no tradition of people participation. The project objective was to implement a low technology, low budget water treatment plant to the village of Molinos. Various aspects have hindered the continued development of the project including both technical and financial. In terms of people participation, the initial approach used was the top-down approach. There was a failure to fully integrate the community or inform the community in a formal manner about the project and consult them regarding key project issues. This case study illustrates that the lack of comprehensive consultation and the low level of participation of the community on the participatory scale does not achieve much in terms of people-centred benefits. For governance at the local level to be effective, participation should be inclusive and communicative so as to enhance transparency throughout the project lifetime.

Local governance of energy transition: sustainability,transactions and social ties. A case study in Northeast France

This paper tackles the process of energy transition from a transactional perspective. It addresses the governance of energy transition by studying its local actualizations, moving beyond purely technical and normative readings. The paper shows that through the local socio-technological energy systems, sustainability governance filters down to the level of individual, everyday behavior, thus questioning the link between public and private spaces, especially regarding the issue of housing. Going beyond the results commonly yielded by transition studies, which favor large-scale analysis, it details how the discourse of citizen involvement, which often boils down to a mere call to control one’s individual energy consumption, conceals environmental inequalities, confirming the socioeconomic divide materialized in deprived areas such as public housing estates or remote rural areas. From a methodological standpoint, the analysis is based on four case studies in Northeast France, in more or less privileged areas, and in both urban and rural environments: the renovation of a heating network in the public housing estate of Cité de l’Ill, north of Strasbourg; the solar energy systems designed for property owners in Plobsheim, a residential suburb of Strasbourg; the energy-efficient equipment set up in a public housing estate in the city of Saint-Dié, in the Vosges; and citizen participation in a cooperative program to finance wind turbines in the small Alsacian city of Saâles, in a mountain rural area. The paper draws on the results of these sociological investigations, carried out using field observations, questionnaires and interviews.     

Community participation in cultural heritage and environmental policy formulation in Botswana

Cultural heritage does not have direct economic benefits. However, if properly managed it can stimulate social cohesions, improving the environment and have beneficial economic spin offs for the local communities. This paper discusses the role of communities in the formulation of the policies concerning their local environment. It argues that community engagement by policy makers is important in giving legitimacy and ownership of the policies. Furthermore, this paper discusses the potential of cultural heritage in diversifying the economy in Botswana. This paper recommends for the re-assessment of the relationship between the state and local communities which is critical in resuscitating the seemingly ailing community business organizations. In conclusion, it argues for the sustainable management of cultural heritage as a social and economic resource in the next 50 years of Botswana’s independence.     

武汉市一次污染过程的局地流场和边界层结构的数值模拟

利用2013年11月武汉市逐日空气质量资料、地面气象观测资料、NCEP/NCAR再分析资料和L波段雷达探空资料，通过WRF模式模拟空气污染生消过程中的局地气象条件变化，探讨特殊地形条件下边界层结构变化和局地环流在污染物生消过程中的作用和影响。结果表明：（1）武汉地区当背景环流场强的时候，由地形引起的局地流场对污染物扩散的影响就弱，反之当背景环流场弱的时候, 地形对流场影响明显:夜间为山风，白天为谷风。夜间山风与偏西北气流及偏东气流在武汉及周边地区辐合，形成气流汇聚带，在武汉地区形成一个反复污染带,即由地形引起的局地流场对污染物扩散的贡献就大；（2）武汉地区发生空气污染时，地面湿度较高，边界层呈上干下湿状态，其特征为暖而干且有偏东小风，这导致污染物不断堆积和重污染过程的形成。     

中国低碳城市试点的政策设计逻辑

政策试点是中国国家治理策略体系的重要组成部分,是中国政府遵循“由点到面”逻辑以试验手段制定政策的一种常规性工作方法。低碳城市试点是中国应对气候变化战略的重要组成部分,通过选择不同类型、不同发展阶段、不同资源禀赋的地区开展试点,探索经济增长与碳排放脱钩的模式。现有文献侧重低碳城市建设的内涵、建设模式与路径、温室气体的核算方法、政策手段、峰值研究与达峰路径、效果评估等,有力地支持了低碳城市建设决策,但对于低碳城市试点的政策设计鲜有涉及。本文从政策过程理论、央地关系两个视角,结合府际学习与竞争关系,建构了中国低碳城市政策“试点–扩散”机制与政府行为的分析框架。中国的低碳城市试点具有探索型开拓性、综合型专业性、授权型自主性的特点,结合三批低碳城市试点的文件要求和实践进展,从政策试点的选点、设计、执行、监督和评估五个方面对于中国低碳城市试点进行了系统的梳理分析。相较于经济领域的其他政策试点,低碳城市政策试点具有弱激励弱约束的政策环境。地方政府基于自身的学习能力和领导力,在政策创新方面表现出争先、自主、效仿和守成四种行为特征,并以杭州、深圳、镇江、成都四个表率城市做了实证。政策“试点-扩散”的过程从本质上讲是中国政策创新与扩散的过程,可能在现实中需要往复多次进行,中国已陆续开展的三批低碳城市试点工作就遵循这样的政策逻辑。试点的意义是试出问题、解决问题、积累经验。从前三批试点城市评估结果来看,试点城市在低碳发展目标设定、转型路径探索和低碳发展动力转换等方面与社会的预期仍有差距,为此本文提出了推进低碳城市建设的四点建议:一是激发城市低碳发展的内生动力;二是完善低碳城市试点的科学论证机制;三是建立激励与约束并举的长效机制;四是强化市场公平竞争的政策导向。     

通风机站风流间相互影响阻力特性研究*

为研究双风机并联机站进口、出口风流相互影响的机站局部阻力特性，构建机站通风局部阻力计算的数学模型，同时运用相似原理建立双风机并联通风机站实验模型，并佐以数值模拟对比验证，分析计算不同风机间距的无量纲数A、不同扩散器结构参数条件下的综合影响系数Kc。结果表明:A与Kc具有二次函数关系，且存在较优的A，使得Kc值最小；Kc值随着L/Df增加而线性减小。研究结果有利于Kc的选取，为高效率通风机站结构设计提供技术及数据支撑。
