There was a decreasing trend in the concentration of nutrients from the north coast to offshore waters of the northern Beibu Gulf, reflecting the influence of inputs from land-based sources. High concentrations of dissolved inorganic nitrogen (DIN) and phosphate (PO4-P) occurred mainly at Fangchenggang Bay, Qinzhou Bay, and Lianzhou Bay. Four different methods were used to assess eutrophication. The trophic status of the Beibu Gulf was characterized using the single factor, Eutrophication index (El), Trophic index (TRIX) and Assessment of Estuarine Trophic Status (ASSETS) methods. Based on nutrient concentrations, 73.9% of DIN and 26.7% of PO4-P samples exceeded the fourth grade Seawater Quality Standard of China. Eutrophication index values varied widely, but higher levels of eutrophication were generally found in bays and estuaries. TRIX values ranged from 2.61 to 7.27, with an average of 4.98, indicating a mesotrophic and moderately productive system. A positive correlation between TRIX and harmful algal species richness and abundance was observed. The ASSETS model evaluates eutrophication status based on a Pressure-State-Response approach, including three main indices: influencing factors, overall eutrophic condition, and future outlook. The Beibu Gulf was graded as moderate using ASSETS. The single factor and Chinese nutrient index methods were considered inadequate for the assessment of trophic status. TRIX can be used as an indicator of trophic state and ASSETS showed good potential to assess eutrophication. The results of TRIX and ASSETS depend on threshold values. To establish these values, further research is required within the northern Beibu Gulf.展开更多

The authors have used the discounted cash flow (DCF) as an alternative method and a model of system dynamics. Such a system dynamics method has not been used for assessment of biological assets so far. In the operating process, the company acquires or loses possession of the resources. It is vital to analyze the resources to see whether they comply with the concept of the assets and the terms of recognition. It is necessary for the same company as well as for external users of financial statements to get true information about the business and the value of money. Biological assets may be recognized in the company's accounting only when it is predictable that future benefits associated with these assets will flow into the enterprise. It is also important that the fair value or the cost can be measured reliably.展开更多

By using the M&A samples ofchina's listed companies, this paper argues that, as the pricing basis, the appraisal value is better than the book value. But the transaction types will influence the function of the appraisal value as the pricing basis. The importance of appraisal value in the pricing of M&A is significantly different in different types of transactions.展开更多

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

As a result, a reasonable prediction of asset-expected future returns has become one of the core contents of the income approach. The forecast on expected future earnings is generally based on many uncertain factors, such as strict conditions of assumption and the complexity of environment. However, the current valuation practice in this aspect varies greatly and sometimes depends on personally experienced judgment of appraisers. Therefore, the obtained valuation results tend to be simplified and absolutized. This paper takes a listed company in China as an example to explore the way of inserting an uncertainty analysis into the prediction of the income approach, and then to obtain a series of valuation results within a certain probability fluctuation range. Finally, it puts forward some suggestions about the Monte Carlo simulation (MCS).展开更多

Due to poor management and policy implications, blind fishing is continued which may result in ecological as well as economic losses. Thus, it is of utmost importance to estimate fishery resources before harvesting. In this study, catch and effort data, 1996-2009, of Kiddi shrimp Parapenaeopsis stylifera fishery from Pakistani marine waters was analyzed by using specialized fishery software in order to know fishery stock status of this commercially important shrimp. Maximum, minimum and average capture production ofP. stylifera was observed as 15 912 metric tons (mr) (1997), 9 438 mt (2009) and 11 667 mt/a. Two stock assessment tools viz. CEDA (catch and effort data analysis) and ASPIC (a stock production model incorporating covariates) were used to compute MSY (maximum sustainable yield) of this organism. In CEDA, three surplus production models, Fox, Schaefer and Pella-Tomlinson, along with three error assumptions, log, log normal and gamma, were used. For initial proportion (IP) 0.8, the Fox model computed MSY as 6 858 nat (CV=0.204, R^2=0.709) and 7 384 mt (CV=0.149, R^2=0.72) for log and log normal error assumption respectively. Here, gamma error produced minimization failure. Estimated MSY by using Schaefer and Pella-Tomlinson models remained the same for log, log normal and gamma error assumptions i.e. 7 083 mt, 8 209 mt and 7 242 mt correspondingly. The Schafer results showed highest goodness of fit R2 (0.712) values. ASPIC computed MSY, CV, R2, FMsv and BMsv parameters for the Fox model as 7 219 nat, 0.142, 0.872, 0.111 and 65 280, while for the Logistic model the computed values remained 7 720 mt, 0.148, 0.868, 0.107 and 72 110 correspondingly. Results obtained have shown that P. stylifera has been overexploited. Immediate steps are needed to conserve this fishery resource for the future and research on other species of commercial importance is urgently needed.展开更多

Under more than 20 years of development which begins to bud in the beginning of the nineteen nineties, the assets valuation industry has become the indispensable Intermediary trade of the socialist market economy system in China. With the scale of assets valuation agency enlarging and its rapidly growing business in recent years, however, some problems have been exposed gradually, which harm the social image of the industry of asset valuation seriously. So the social public and the relevant administrative departments pay close attention on the quality of the asset valuation. To know about what are the essential causes that affect the assets valuation industry managers' decision, this paper, through using some means which include literature research, interview and questionnaire investigation and utilizing the method of the factor analysis, relegates 24 questions which come from some answers of the respondents to three factors which are the practicing quality factor, the sting factor of an organization and the internal management factor of valuation organization. Furthermore, it will analyze the features of these factors which are divided into two factors that are internal motivation and external motivation, looking for the key cause of the assets valuation industry quality problem of China which purposes in order to promote the healthy development of valuation profession and much better standard the internal quality of valuation industry of China.展开更多

Its positive influence on consumer health is caused by grain composition. With the aim of selecting varieties or landraces for their possible further use we tested selected emmer wheat accessions maintained in the Czech Gene Bank. In the set of 8 emmer wheat accessions, the main grain components, bread making characteristics and contents of health supporting chemical substances such as total dietary fibre content and its components, content of total polyphenols plus catechin and ferulic acid contents, vitamins of the B group and E plus total content of carotenoids were evaluated by standard methods. Tests of bread making quality confirmed a very well known fact that emmer wheat grain is much more suitable for other purposes as whole grain mixtures, cereal pure, etc. than for bread preparation. The results indicate the possibilities to select emmer wheat genotypes differing in grain composition and containing compounds with positive effects on human health. Among the tested emmer wheat accessions the Rudico variety had a complex of positive characteristics such as content of total dietary fibre, total polyphenol content with prevailing catechin and the highest amount of B group vitamins such as B 1, B2, niacin, pantothenic acid and B6.展开更多

A high coefficient of variation (CV) of the catch and effort values biased the estimates of MSY and EMsv. Thus, the state of the fisheries resource and its exploitation was overestimated. We compared the effect using three surplus production models, Hilborn-Waters (H-W), Schnute, and Prager models. The estimates generated using the H-W model were significantly affected by the CV. The Schnute model was least affected by errors in the underlying data. The CVof the catch data had a greater impact on the assessment than the CV of the fishing effort. Similarly, the changes in CV had a greater impact on the estimated maximum sustainable yield (MSY) than on the corresponding estimate of fishing effort (EMsY). We discuss the likely effect of these biases on management efforts and provide suggestions for the improvement of fishery evaluations.展开更多

However, in certain cases, it can reduce the results obtained by other products of the same company. This fact is named "cannibalism". Following by a review of the literature on cannibalism between goods, this paper outlines a conceptual approach, showing the way it happens, its impacts, and the possibility of its uses as a marketing tool. A new product should, wherever possible, be carefully designed to avoid cannibalizing old products, unless this process is carefully planned. Concludes that creating and launching of new products are critical to companies who want to stand out next to their markets and need to survive over time. A lot of new products launched each year, coupled with the fact that most are line extensions already worked by companies, so we assume that the occurrence of cannibalism is common, or that a significant amount of resources are designed to prevent or dilute it. There is a high probability of transfer of results obtained by established products to new products, since similarity between展开更多
