通过财务稽核强化电力企业的内部控制

通过对财务稽核的意义、作用以及电力企业内部控制的基本要求,阐述财务稽核对强化企业内部控制的重要性,同时列举电力企业管理中容易出现的财务管理方面的漏洞,并依次作为问题进行讨论寻找解决的途径。     

多目标随机结盟对策的区间模糊ZS -值

内部控制和企业价值之间存在着密切的联系，内部控制是否有效及效率高低影响着企业的价值。内部控制质量高的企业有动机通过自愿性信息披露向市场传递企业价值较高的信号，由于信号传递作用，企业更容易获得较低成本的商业信用和银行信用借款，提升了企业价值，而内部控制质量低的企业没有动机进行内部控制信息披露，从而不得不付出较高的债务融资成本，降低了企业价值。     

Microphytic crusts,shrub patches and water harvesting in the Negev Desert: the Shikim system

Human-made contour banks are a central component of theShikim water harvesting system in Israels Negev Desert.Efficient water capture depends on the presence of a stable microphytic crustwhich directs surplus surface runoff into the banks where it is stored. We usedsimulated rainfall to examine the impact of soil surface disturbance on runoffand sediment transport, and the effect of this on the efficiency of resourcecapture within the Shikim system. Two disturbance regimes:1) removal of the microphytic crust only, and 2) removal of the crust and shrubpatches by cultivation, were compared with an undisturbed control. In theundisturbed state, 32% of rainfall was redistributed as runoff. This runoffpenetrated approximately 27% deeper under the shrub patches compared with themicrophytic crust. When the microphytic crust was destroyed by simulatedtrampling, the runoff coefficient declined to 13%, and there was no significantdifference in water penetration between shrub and crust patches. Completedestruction of the shrub hummocks and crust by cultivation resulted in adeclinein the runoff coefficient to 6%. The result of sustained disturbance in thesepatchy Negev shrublands is a breakdown in spatial heterogeneity, a loss ofecosystem function, a reduction in ecosystem goods and services such as plantdiversity and production, and ultimately a reduction in pastoral productivity.These results reinforce the view that microphytic crusts are critical for theefficient operation of the Shikim water harvesting system.Given that practices such as cultivation and trampling which disturbmicrophyticcrusts result in enhanced infiltration, crusts should be left intact tomaximisethe water harvesting efficiency in these desert landscapes.This revised version was published online in May 2005 with corrections to the Cover Date.

The effect of cattle foot traffic on soil compaction in a silvo-pastoral system

In India, small farmers have generally found that the growing of eucalypts as a cash crop provides poor returns, and many have reverted to growing annual crops. Farmgate prices have been much lower than retail prices, due to the existence of middlemen, and retail prices have fallen to lower levels than expected as markets have become saturated. This article describes the situation in eastern Gujarant, where farmers sold their eucalypts directly to buyers at prices close to those in organised wood markets. An important reason for this unusual situation is the absence in Gujarat of controls on eucalyptus sales, which has helped producers to avoid dependence on rent-seeking intermediaries. The survey shows that growing eucalyptus can be a profitable activity for small farmers, given the right circumstances.     

非系统风险与公司最优资本结构

综合运用格兰杰因果检验和分位数回归技术对我国影子银行的各种影响因素进行实证分析。结论表明,我国影子银行是在金融二元结构和利率管制格局下,金融活动主体为规避监管、分散风险以及投机套利而进行金融创新的产物。利率管制是促成我国影子银行发展的根本原因,经济结构变迁、经济周期运行及宏观调控政策在总量与结构层面作用于金融资源供求关系,通过扩大或收缩监管套利空间,也对影子银行规模变动产生了重要影响。     

基于超越方程的喷泉自适应控制模型研究

分析风对水滴的影响所产生的偏移，得到在风力作用下的水滴偏移方程，由此建立风速与水初速度的关系；通过对基本模型的优缺点分析，改进后得到更符合实际情况下的风速与水的初速度的关系，给出解决在风的作用下水滴偏移对游客产生的负面影响的优化控制模型。综合考虑实际情况，给出模型进一步改进的方向，从而进一步扩大模型的应用范围。
