A more objective and veracious supplier selection and evaluation method based on fuzzy analysis hierarchy process and grey relational analysis was developed, and then empirical research on electric equipment manufacturer was explored to analyze the supplier selection and evaluation.展开更多

The...On the Loess Plateau of China, facing the vulnerable environment, local people have to try their best to guarantee the security of food, and at the same time, to control the most serious soil erosion in the world. The paper introduces two typical models of ecological agriculture: ecological agriculture with commodity and agri- culture with soil and water conservation. According to the local natural condition, the model of eco-agriculture with commodity could be characterized by the structure of “agriculture-byproduct”, “agriculture-fruit” or “agri- culture-forestry-husbandry”. The development of agriculture with soil and water conservation has decreased the soil erosion rate from 12,184 ton/km2 in 1980 to 458.4 ton/km2 in 1999, while the farmers’ income has increasingly risen. Analyses on the two models’ benefits both in terms of ecological and agricultural economy show that there is a great possibility to construct or restore good eco-environment with comprehensive control in the hilly-gully area of north Shannxi. Further more, the paper points out the potential problems of foodstuff production and stockbreeding development in forming ecological agriculture and eco-environmental restoration.展开更多

This paper attempted to analysis the production pattern and trade pattern of global cereals, especially three main crops of wheat, maize and rice by using the method of share-shift. Given the fact of almost every economic phenomenon is driven by their economic return behind them, this paper attempted to a further step into their economic pattern by examining their net trade flow. The results showed that from the view of production and trade, the geographic pattern of global cereals has changed greatly which can be described as developing countries has replaced developed countries and become the world's biggest cereals production and trading area. But when moving to the net trade flow, it turns out to be another story that can depicted as the regional fixation features of economic returns which can be convinced from the labor division of global cereals trade, among which developed countries acts as net trade profit area while developing countries as net trade output area, and their gap between net export and net import has been widening from the view of evolution trend. So what we learn from the evolution of geoeconomic pattern on this topic is that our place in global cereals trade system, and therefore alert us to concern not only on the pattern transition but also the economic meaning behind it, only by doing so can we learn to plan our food future more wisely and effectively.展开更多

Indeed, the trends of a global economy, especially one relying on a capital market-based financial system, are greatly influenced by reliable accounting information. However, it is sometimes difficult to assess the ＂reliability＂ of such information, given the clear differences in the needs and goals of its different users. In this respect, the possible ways to guarantee the appropriateness of the accounting information provided to users doubtlessly deserve a careful investigation. The second half of the 1970s can be considered as the starting point of a debate, within the Anglo-Saxon accounting literature, concerning the most effective methods to provide users with accounting data effectively meeting their very specific needs. In this context, two antithetical schools of thought developed： （1） free market approach; and （2） regulatory approach. Although it is possible to state that accounting regulation has now become a concrete reality both inside and outside the Anglo-Saxon accounting context, after more than halfa century, its efficacy is still an open issue.展开更多

The modelling treats the reaction kinetics of substrate （S）, the micro-organisms （X） and the ethanol （E）. Nine models are taken from the literature to describe specific organism growth rate and specific ethanol development rate. These models treat all types of fermentation. The Phisalapbong et al. model and the Ghose and Tyagi model show the best fit of the experimental data. This affirms that the batch fermentation of carob is conducted with substrate and/or ethanol inhibition. Some simulations and relationships （X = f（S）, E = f（S）） are obtained from the Phisalaphong et al. model. Those simulations show a lot of important and useful results of carob batch fermentation process.展开更多
