Study on the Current Situation of the Public Dance Course Teaching in General Colleges and Universities

In the public art education, the public dance course plays an important influence, and has become an important way of the aesthetic education in general colleges and universities. However, the public dance course teaching in China＇ s colleges and universities is a necessary way for ensuring the effective implementation of the public dance course teaching, because there are certain unsound teaching problems in the public dance course teaching in China＇ s colleges and universities currently. Therefore, it is necessary to carry out deep research and practice for the public dance education in China＇ s colleges and universities, and this plays an important role in promoting the development of general colleges and universities＇ quality education for students, advancing the further development of the current genera/colleges and universities＇ public dance education, and enriching the existing public art education theories. There are many problems such as unclear teaching goals in the existing public art course teaching model, non-systematic and non-scientific teaching contents, simple teaching forms, and simple teaching methods in the general colleges and universities, so it is urgent to explore new teaching models. The purpose of this paper is to build a three-dimensional public dance teaching network from both forms and contents. Public dance course is a selective course, which is established for training the high-quality personnel demanded by the modernized construction of socialism, and plays an irreplaceable role in improving the aesthetic quality, cultivating the innovative spirit and practice ability, and shaping a healthy personality. On this basis, the current situation of the public dance teaching in general colleges and universities is investigated by taking the public dance teaching in Guangxi Normal University as an example and using the methods such as document literature, questionnaire survey, and interview, and the specific situation of the dance teaching in general colleges and universities is analyzed, and also corresponding strategies and suggestions are proposed.

Contemporary Marxism and the Global Concept of the Universe

Having been developed in the way of concept extension, Marxism appears to be nowadays as the concrete-universal theory, in which originally imperfect transition program from abstract-universal to concrete-universal concepts of logic and sense is realized on materialistic foundation. This very program that was brought about in Karl Marx＇s ＂Capital＂ has not been sufficiently expressed in classical or contemporary philosophy. The base of this new Marxist philosophical form is not constructed by the terms of matter, movement, and development overall, but by the conception of the general naturally determined universal process of infinite movement from lower to superior forms of matter. We are aware of four of them： physical, chemical, biological, and social matter. Representing the eternal world as the progressive whole, modern materialism makes nature and proper place of each fundamental science understandable and helps to clarify the location and development future trends of the Man in the world.

On the Large-Scale Structure of the Universe as given by the Voronoi Diagrams

The size distributions of 2D and 3D Voronoi cells and of cells of Vp（2, 3）,--2D cut of 3D Voronoi diagram--are explored, with the slngle-parameter （re-scaled） gamma distribution playing a central role in the analytical fitting. Observational evidence for a cellular universe is briefly reviewed. A simulated Vp（2, 3） map with galaxies lying on the cell boundaries is constructed to compare, as regards general appearance, with the observed CfA map of galaxies and voids, the parameters of the simulation being so chosen as to reproduce the largest observed void size.
