基于计量经济模型的新疆油气资源与经济发展关系的分析

在对新疆地区油气资源进行分析后,我们利用计量模型对新疆地区的油气资源和经济发展的关系进行了较为详细的分析。结论认为油气资源是新疆地区经济发展的原动力,科学合理利用新疆地区的油气资源不仅有利于该地区的经济发展也有利于保障全国的安全。为此,我们可以从加强油气勘探力度,扩大资源后备储量;加速新疆油田、天然气开发;做长油气产业链,增强新疆石油产品的竞争力;加强管理,降低成本,提高油气企业经济效益;制定相关鼓励政策,加速油气开发利用。

利用HS-GC/MS和响应面法分析纸中溶剂残留的方法研究

本研究以N,N-二甲基乙酰胺为稀释剂,使用顶空-气相色谱质谱联用分析法（HS-GC/MS）测定了纸质包装材料中常见的8种有机溶剂的残留。采用HP-5MS色谱柱分离有机溶剂,He气流速为1ml/min;进样口温度250℃;升温程序为初始温度35℃,保持3min,以10℃/min速率升温至100℃,保持2min,共11.5min可以将8种有机溶剂分离开来。运用响应面法优化前处理温度和时间,发现前处理温度对峰面积影响显著,而前处理时间影响较不显著;最佳前处理温度为100℃,时间40min。该实验条件下,计算回归方程和相关系数,根据信噪比（S/N）为3,确定检出限。结果得到：8种残留溶剂的线性范围为0.330-7.956mg/m~2,线性相关系数为0.9952-0.9997,检出限为0·01-0.38mg/m^2;加标回收率为99%-114.8%,相对标准偏差RSD（n=5）为0.916%-1.455%。     

An agency perspective on the accounting costs used in various roles in the regulation of a state-owned natural monopoly: The British Gas Corporation 1972-86

This study describes and analyses the accounting costs reported in the financial statements of the British Gas Corporation (BGC) during its fourteen years (1972-86) as a state-owned natural monopoly. Evidence is provided of the various roles in which these accounting costs were used in the regulation of the corporation. The agency perspective developed by Whittington (1985) is used to provide an analytical framework for discussion of the effects of BGC's accounting costs on the allocation of burdens and rewards between gas consumers and taxpayers through being used in these various roles. Further analytical insights are drawn from developments subsequent to privatisation in 1986.     

取消燃气和电力补贴对我国居民生活的影响

分析取消能源补贴对居民生活的影响是完善能源补贴改革的重要基础。本文首先应用价差法估算了中国2007年燃气和电力的补贴规模;其次考虑到中国居民贫富与区域差异,将城乡居民按收入水平分为10组,引入"能源预算"概念并设计"影响指数"、"承受力指数"等核心指标,结合投入产出模型,从直接和间接两方面综合研究了取消燃气和电力补贴对不同收入阶层居民生活的影响,分析结果表明无论从直接影响还是间接影响的角度,取消燃气和电力补贴对低收入阶层居民,尤其是农村低收入居民的冲击更大。最后基于实证分析结果,提出阶梯化定价机制与补贴转移等能够让低收入阶层居民真正获益的能源补贴改革建议。

Challenges for ground operations arising from aircraft concepts using alternative energy

Current research in the field of future aircraft concepts aims at accommodating ambitious reduction goals set by national and international regulators. These concepts should be investigated not only with regard to aircraft efficiency, but also in terms of their compatibility with airline operations, existing ground handling procedures and airport infrastructure requirements, as these influence the overall performance of a future aircraft concept. This paper addresses this aspect, focusing on case studies concerning hybrid-electric and universally-electric aircraft concepts, analyzing implications for current ground handling operations at the airport. Current bottlenecks, such as capacity shortages, and potential areas of improvement are identified based on a state-of-the-art reference ground handling process. To this end, requirements of different stakeholders, including airports, airlines and ground handling providers, are outlined. In the next step, insights are contrasted with operational requirements of the future aircraft concepts under consideration. The paper stresses the anticipated challenges involved in aligning future aircraft requirements with current procedures, discusses the necessary adaptions to operational processes. The results highlight changes that need to be made to the current system before an aircraft can enter service, and provide an initial basis for the strategic planning of the stakeholders involved.

When the uncountable counts: An alternative to monitoring employee performance

This article presents an alternative viewpoint to the accepted wisdom that detailed performance measurement of individual employees is necessary to achieve superior performance. As we reveal, managers of a market-leading German energy distribution company do not utilize performance measures to manage the performance of their employees; rather, operational excellence is achieved through mechanisms ultimately based on trust and responsibility. Building on observations at this firm, we put forward a set of proposed characteristics of companies that may not require formalised individual performance measurement systems in order to achieve high performance standards.
