Experiences with greening suppliers. The Universitat Autònoma de Barcelona

This paper explains the strategy and procedures followed by the Universitat Autònoma de Barcelona (UAB) to spread green purchasing practices throughout its administration and supply chain, highlighting the identified barriers against their implementation and monitoring, and showing the actions carried out to overcome them. The university's green supply chain management has been analysed in five selected case studies: office material, recycled toner cartridges, fair trade coffee, reusable glass bottles and catering services. These cover the wide range of purchasing patterns currently taking place at UAB taking into account both the acquisition model (directly or indirectly through contracted firms) and the supply chain management perspective (linear or loop). A comparison of the different cases is carried out and some general rules are created that should be investigated further.     

基于彼得斯治理理论的京津冀协同发展路径重构

基于彼得斯治理理论,分析了京津冀地区的协同发展现状和要求,重构了其协同发展路径。结果表明:①要素禀赋、区域政策分别是区域协同发展的客观基础和主观条件。②区域协调发展新机制为京津冀地区提出了“坚持以北京和天津尤其是以非首都功能疏解为引领,借助市场力量调动各个主体的积极性,同时注重协同方式(机制)建设”的新要求。③京津冀协同发展路径重构可从“由软硬兼施的市场(市场平台和政府效能)、三维协同的主体(地方政府,中央政府和非政府部门)和富有弹性的方式(临时机构和互动机制)”的“3M”策略入手。     

企业如何实现真正意义上的节能减排

面对严峻的能源及环境形势,国家大力推行企业节能减排工作。部分企业在节能减排工作中出现了过分追求污染物处理效率,盲目投资建设末端治理设施而忽略生产过程中的污染控制。针对这一问题分析原因,并对企业如何实施节能减排,实现真正意义上的降低能源消耗、减少污染物排放提出建议,通过加强企业管理,促进企业清洁生产及着力技术创新、加大科技投入,使企业实质性地完成节能减排目标,实现可持续发展。     

Single and multiple daily dose toxicokinetics of fluoride after oral administration of sodium fluoride along with aluminum sulfate in goats

Our previous study suggested that toxicokinetic parameters of fluoride were significantly changed on the 30th day as compared with 1st day, after repeated oral administration of sodium fluoride alone for 30 days in goats. The purpose of this study was to investigate whether aluminum sulfate has ameliorative effect on the toxicokinetics of fluoride. For this, sodium fluoride (20 mg kg^?1 b. wt.) along with aluminum sulfate (150 mg kg^?1 b. wt.) was administered in goats for 30 days to investigate its effect on toxicokinetics of fluoride on days 1 and 30. The fluoride levels against time were adequately described by one compartment open model. The peak plasma level of fluoride was observed at 2 h. The toxicokinetics data revealed a nonsignificant decrease in β (elimination rate constant) and C _max (the maximum plasma concentration) and increase in t _1/2 K _a (absorption half-lives), t _1/2 β (elimination half-lives), area under the plasma (AUC) concentration versus time curve and mean residence time (MRT) was observed for the last dose from their respective first dose values. On the basis of changes in the toxicokinetic parameters, it was concluded that repeated oral administration has cumulative effect on plasma fluoride level and concurrent oral administration of aluminum sulfate has ameliorative action on the toxicokinetics of fluoride in goats.     

煤炭安全成本及其变动趋势分析

煤炭安全成本是煤炭生产的一种"附加性成本",它是煤炭企业安全工作质量的综合反映,是安全决策和安全工作评价的重要指标.对于煤炭企业来讲,安全生产的特殊性决定了安全成本在煤炭生产成本中占有很高的比例.研究煤炭安全成本及其变化趋势,对于促进安全与生产的协调发展,合理控制安全投入和优化安全成本结构,都具有重要的理论价值和现实意义.本文结合煤炭生产实际,理论与实践相结合地提出了安全成本分析指标,并在现场调研的基础上,利用调研资料,采用回归分析方法,对安全成本进行了变动趋势分析,建立了煤炭安全成本分析模型.通过模型分析得出了安全成本随安全保证程度而变化的规律.安全成本趋势分析及相关分析模型的建立,为煤炭企业进行安全管理与决策提供了有效的分析手段.
