论道具在鲁迅小说中的美学功能

"无不浸润着中国古典文学的滋养"[1]的鲁迅,在小说创作实践中,善于学习中国古典文学利用"道具"导引故事情节发展,揭示小说主题、塑造人物形象、见证人物命运的传统。鲁迅先生在小说创作中设置的各种道具,都被赋予了特殊的美学功能和审美价值。

Anomalous Dissipative Quantum Harmonic Oscillator

We investigate the low-temperature statistical properties of a harmonic oscillator coupled to a heat bath, where the low-frequency spectrum vanishes. We obtain the exact result of the zero point energy. Due to the low frequency shortage of environmental oscillators＇ spectral density, the coordinate and momentum correlation functions decay as T^-4 arid T^-6 respectively at zero temperature, where T is the correlation time. The low-temperature behavior of the mean energy does not violate the third law of thermodynamics, but differs largely from the Ohmic spectrum case.

Educational Practices in the Model of Music Learning Theory of E. Edwin Gordon： An Observational Research

This paper analyzes the supervision activity, to which educators and teachers enrolled with AIGAM （Gordon Italian Association for the Musical Learning） are subject to every year and intends to verify the application of those principles expressed in the learning model of the MLT （Music Learning Theory） developed by educational psychologist E. Edwin Gordon （1989, 1999, 2000, 2001, 2007） and promoted internationally by various institutions and organizations specifically accredited. It describes the influence of the videotaped supervision on the process, functions of monitoring, and evaluation of educational practices, starting with an empirical model that has guided the interventions in a study of supervision on training aimed at consolidating and developing professional skills in music education in early childhood. This paper sought to understand： the kind of practices, interactions, communications developing during an educational actions, the existence of a consistent relationship between the principles expressed in the MLT and their application, the type and benefits of supervision performed by of video recording on stakeholders in terms of change in professional behavior, and finally whether the active supervision could be comparable with other kinds of approaches.

Stakeholders： the extension of service function of modem universities

Various ＂stakeholders＂ come into being around modern universities. Their emergence is based upon responsibility and contribution of extending university function to social public interest. Definitive stakeholders, expectant stakeholders and latent stakeholders constitute the objects of universities achieving their service function. Thus, management mode of universities undertakes exploration and reform. Yet ignoring part of the management status of ＂stakeholders＂ can also affect that universities fulfill their social responsibilities and promote their service functions to some extent.

Fracture healing with osteopathy in traditional Mongolian medicine

OBJECTIVE: To explore the concept and norm of fracture healing with osteopathy in traditional Mongolian medicine (TMM). METHODS: Based on the correspondence between man and the universe (including psychosomatic integration) in fracture healing with osteopathy in TMM, we used modern physio-psychological and biomechanical principles and methods to probe the integrated, dynamic and functional characteristics of fracture healing. RESULTS: Based on the integration of limbs and the body, unification of the body and function and harmony of man and nature (including psychoso-matic integration), fracture healing with osteopathy in TMM comprises the concept of natural functional healing of fractures, and follows the norm of considering physiological healing and psychological function as well as limb healing and motor function. CONCLUSION: Fracture healing with osteopathy in TMM is characterized by a lack of trauma without future complications. This therapy makes the concept of fracture healing develop in the direction of humanity, behaviorism and integration.

Mechanochemistry enables optical-electrical multifunctional response and tunability in two-dimensional hybrid perovskites

Two-dimensional(2D)organic-inorganic hybrid perovskites(OIHPs)have attracted phenomenal attention because of their superior optoelectronic performances.The combination of their structural tunability and material stability offers an unprecedented opportunity to engineer materials with unique functionalities.However,developing a rapid and effective design method for introducing luminescence into dielectric switch and realizing controllable regulation has been an enormous challenge.Thus far,materials with tunable optoelectronic multichannel response have not been successfully implemented.In this study,we successfully developed a facile and effective mechanochemical method for realizing the integration and regulation of luminescence and dielectric switch in 2D perovskites,which is unprecedented for the design of dielectric switching materials.The mild external mechanical stimuli enabled the formation of Mn ion-doped 2D hybrid perovskites(Cyclopropylammonium)2Pb1-xMnxBr4 with excellent dielectric switch and rapidly controllable luminescence of highly efficient blue light,white light,pink light,and orange light.This work will provide a new perspective on the rapid and effective design of multifunctional materials and can inspire the future development of low-cost and high-efficiency electronics.
