Its main objective lies in the will instead of hope. The era endows different aesthetic utopian meanings to ＂Pop Songs between 1930s and 1940s in Shanghai＂. After 2010, the utopian change of such songs is closely related to the contradiction between ＂aesthetic imagination and reality＂, and ＂individual interest and integrated social interest＂ that are intrinsic in the utopian concept. To sort out the utopian process of those songs, it is helpful for correcting the current status about the weakened critical realism function of the current art, and accelerating the arousal of the literary and artistic creation, and individual consciousness, laying equal stress on and gathering the aesthetic power of these individuals, which provides solid foundation for the generalization of aesthetic utopian significance.展开更多

In this study, the scientific aspects in highly cited papers and hot papers, published in the last year in the core collection of Web of Science, were taken as objects, and office software was used as the main tool to carry out bibliometric and figure analysis. From the four aspects to find the difference in these fields, the production of specific fields and cited times is inconsistent.
