The asymmetric local value is expressed as the product of a weight function and a symmetric local value. The symmetric distribution is expanded into Fourier-Bessel series. The coefficients of the series are determined by the use of a least-square-fitting method.展开更多

At the time when the country is dealing with impacts of the global financial crisis, the All-China Federation of Trade Unions has been working fruitfully and effectively to accelerate economic and social development and safeguard the legitimate rights and interests of workers, therefore making contributions to the protection of the rights and interests of Chinese workers. Now I would like to make a brief introduction on this subject.展开更多

Such a situatio...Without cooperative behaviors, our society or organization falls into social dilemma situations where every member selects uncooperative (defective) behaviors, and the situation gets worse and worse. Such a situation in a society or an organization leads to violation of social or organizational rules, and at the worst case it suffers from serious accidents or scandals. Therefore, it is important for us to make efforts and take measures to elicit cooperative behaviors. It was demonstrated theoretically that altruism strategy and adaptive prediction and ascertainment strategy are in some cases better than rational strategy under the situation of social dilemma. We built up a mathematical model in order to examine how the probability of correctly predicting and ascertaining the behavior (cooperation or defection) of opponents and the mixture of (a) altruism (all cooperation) strategy, (b) individualism (all defection) strategy, and (c) adaptive prediction and ascertainment strategy affected the expected profit. Simulation results showed that the tit-for-tat strategy was better than the rational (individualism) strategy when the probability of correctly predicting and ascertaining defection of the opponent was considerably higher. As an application of the basic study above, it was explored, using a simulation method, how such a system as opening reputation or peer review in public could work satisfactorily to prevent defective behaviors in auction dealing. The result showed that the information on the handle name and the reputation effectively worked to prevent defective behaviors.展开更多

In addition, it expounds the necessity, urgency and cardinal significance in promoting related scientific research in this country. The authors stress that research work should be concentrated on the ecological effects of non-indigenous species in the light of the national demands, world research frontiers and high-tech application. That involves the process of an invasive organism's immigration and propagation, short-term evolution, latent buildup, ecological adaptation, competition and outbreak as well as the process in which the new ecosystem's original structure and functions unfold their role of rejection and assimilation.展开更多
