This paper investigates the existence and the characteristics of different types of daily MFD for the Shanghai urban expressway network. The existence of MFD in the Shanghai urban expressway network is proved based on two weeks＇ data.Moreover, the hysteresis phenomena is present in most days and the network exhibits different hysteresis loops under different traffic situations. The relationship between the hysteresis phenomena and the inhomogeneity of traffic distribution is verified. The MFDs in the years of 2009 and 2012 are compared. The hysteresis loop still exists in 2012, which further verifies the existence of the hysteresis phenomenon. The direct relationship between the length of the hysteresis loop（ ΔO） and the congestion is proved based on sufficient data. The width of the hysteresis loop, i. e., the drop in network flow（ ΔQ） has no relationship with the congestion, and it varies from day to day under different traffic situations.展开更多

Therefore, the aim of this article is to investigate the phenomenon of multi-dimensional musical experience from a life-world-phenomenological perspective and indicate its benefits to music education. The analysis is informed by Dufrenne＇s philosophical writings regarding the phenomenology of aesthetic experience and also draws on Merleau-Ponty, Heidegger, interpreted by Benson and Ford, together with Schutz. These philosophers provide tools for understanding musical experience from a bodily, existential, and sociological perspective, and their complementary ideas about being and learning can be applied to musical experience in the first case and secondly its influences for music educational praxis. Firstly, the concept of lived music is defined through a discussion of dimensions of musical experience; the phenomenology of aesthetic experience; the use of several senses; the heard and the hear-able; apperception; and musical dwelling. Then, the sharing of experience in musical dwelling and its relevance to the concept of imagination is highlighted. I will also emphasize the importance of the view of human beings as holistic bodily subjects. Finally, the article includes a discussion regarding the implications of a life-world-phenomenological view of musical experience to music education.展开更多
