In this paper, the authors present an analytical approach through the Structuration Theory： How a university can assess its culture for the purposes of design and development of the ERPs. The authors extend the Structuration Theory by integrating it with the Activity Theory to provide the means of evaluating the activities that the system is to perform. The modified Orlikowski model is applied to depict the relationship between institutional properties, human agents, and technology in the university setup and how this offers a more inclusive approach to ERP systems development and implementation.展开更多

The latter holds that Damasio does not distinguish the concepts of phenomenal consciousness and self-consciousness and this has two kinds of consequences. One is that it cannot satisfactorily explain certain mental states （dreams, vegetative states）; the other is that it has harmful consequences for animal ethics. I maintain that to compare the two theories we can only rely on our pre-theoretical intuition of consciousness. Thus, I argue that Dam^tsio＇s theory combines more with our intuitions. One of the reasons is that the cases that Block describes as phenomenal consciousness without access consciousness （and without self-consciousness） are best explained as being cases of mind without consciousness. Dam^sio＇s theory can also explain those referred cases which are theoretically problematic. Moreover, Dam^isio has a threshold model （an expression by Barry Dainton）, which is something that Block seems to ignore. This model fits well with the intuitions and neurological knowledge that we normally have on animal consciousness. Dam^isio＇s core self and his theory of emotions and feelings allow us to understand why we feel compassion for animals. Therefore, we are able to develop an animal ethics, which does not mean that we are required to do so. So even though Damasio does not solve the mystery of consciousness, he should not be the subject of Block＇s criticism.展开更多

It's an important task that we are facing to apply the fruits of SLA research to China's English teaching practice. This paper, based on the guidance of second language acquisition (SLA) theory, studies and explores the interaction of language acquisition and classroom instruction and effective classroom teaching methods.展开更多

The essence of the work is to solve two important problems, one for positions of the pilot valve influenced by flow force and the other is for the opening of the relief valve governed by a thin annular plate. The computational fluid dynamics(CFD) method is used to present the flow force. Using a series of experiments, the flow rate versus pressure drop shows the rationality of the CFD results. In order to obtain the opening of relief valve with higher accuracy, the large deflection theory of thin plates is adopted. An equivalent method for replacing the concentrated force is innovatively proposed so that all of the loads of the plates can be given by a unified expression, which reduces the number of the governing equations and intermediate boundary conditions. For presenting a very simple and reliable method for solving the governing equation, an unconstrained nonlinear optimization is innovatively introduced to solve the deflection of the thin annular plate. Being verified by finite-element method(FEM) of the relief valve, the equivalent method and optimization can solve deflection of thin plates rapidly and accurately. Reflected through a complete model for the pilot relief valve, the theoretical flow rate of the pilot relief valve is consistent with experimental conclusion. Once again, the comparisons bring us insight into the accuracy of the method adopted in the current work.展开更多
