This definition is not only quite different from the one in the accounting standards, but also difficult to explain in the perspective of asset valuation. This paper focuses on the ＂Fair Value＂ in order to make its relevant meaning and application scope clear in accounting and asset valuation respectively. The discussion helps to avoid the abuse and the misunderstanding of ＂Fair Value＂ for the sake of vague definition.展开更多

The typical network flow is used to find the feasible flow and add the discharge water to different cascaded hydroelectric power plants at the same step. The same period network flow is used to find the optimal flow and add the power output at a different step. This new algorithm retains the advantages of the typical network flow, such as simplicity and ease of realization. The result of the case analysis indicates that the new algorithm can achieve high calculation precision and can be used to calculate the optimal operation of cascaded hydroelectric power plants.展开更多

This may be linked with the large number of market intermediaries who act between the primary producers and the markets. The sample for the study comprised 250 cashew nuts marketers who were randomly selected from the five south westem states of Nigeria. About 76 % of the cashew nuts marketers had up to secondary school education and 86% of them had 15-year marketing experience and below. Pricing efficiency of the marketers was highest in Ogun state with average efficiency level of85.1% and least for Oyo state （68.9%）. In all, 720 tonnes were transacted in the region with 206 marketers handling maximum of 2 kg per month per individual. Gini-coefficient estimate of 82.3% implied that there was a concentrated market for the cashew nuts. To further increase the pricing efficiency of the commodity it is necessary to reduce the costs incurred on various physical aspects in marketing system. Corporate organizations, government agencies and co-operative societies should assist the cashew nuts marketers in the provision of credit facilities so as to ensure a higher level of pricing efficiency, stable market prices and reduced level of concentration of the marketers.展开更多
