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 NGO sector does not contemplate the emerging trends of agribusiness enterprises in terms of the current and future scenario in context of more efficient agro food systems under the network paradigm. Two of the many NGOs that are engaged in rural development launched various programs to support more efficient marketing systems as the precondition of better well-being. These two NGOs and their various development activities relevant to agribusiness enterprises have been analyzed in this study. The findings reveal that the evaluation matrix for the market activities of these two NGOs characterizes much potential. They are more efficient to strengthen the link between the farmers, market and rural development initiatives. However, in order to improve the linkages NGOs have to act for improving knowledge management in a more holistic way.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

Each module is autonomous to some extent. Development relies on the self-organized patterns that emerge from the interactions of individual modules. Interactions include both competition and cooperation,and several types of positive and negative feedback loops are involved. Development can be open to external influences, thus enabling the plant to adjust its form to the environment,for example, to the spatial distribution of ecological resources. This paper provides a review on adaptive plasticity in plants.展开更多
