It is proved that speculative activities did contribute to high crude oil prices after the Asian financial crisis and OPEC＇s output cut in 1998. The unidirectional Granger causality from returns of crude oil prices to speculative activities is significant in general. But after 2000, with the sharp rise in crude oil prices, this unidirectional Granger causality became a complex nonlinear relationship, which cannot be detected by any linear Granger causaIity test.展开更多

Architectural design teachers in different colleges and universities do not have a unified approach,which easily leads to confusion in teaching.This study put forward “ 3W ” teaching method,and made a preliminary discussion on its concept,structure and application.“ 3W ” method is a method that the architectural design instructor uses three progressive questions to guide the whole process of architectural design.Through a detailed discussion of the three questions,it showed that this method was a building design guiding method with simple operation,easy grasp and adaptability.展开更多

The fact that contemporary philosophy has gone far beyond transcendental philosophy can be seen clearly in the following respects: the response to the Scientific Revolution;the dualistic theory of qualities;the two concepts of the thing-in-itself;and how to know the thing-in-itself. In order to deepen the discussion of the thing-in-itself, it is necessary to introduce probing new questions and attempt to elucidate a switching theory of reality that distinguishes between the meaning-impoverished thing-in-itself and the meaningrich thing-in-itself, and advocates placing the focus of philosophical thinking on the latter.Basing ourselves on the switching theory of reality and the total perspective concept that it implies allows us to better understand man's place in the universe and the mission of philosophy in the post-metaphysical era.展开更多
