An Emergent Phenomenon is a property that is a result of simple interactions that work cooperatively to create a more complex interaction. Physically, simple interactions occur at a microscopic level, and the collective result can be observed at a macroscopic level. The developed Hypersphere World-Universe Model (WUM) introduces classical notions, when the very first ensemble of particles was created at the cosmological time π<sub>M</sub> ≅ 10<sup>-18</sup> and become possible to introduce the notion “Medium of the World”. We emphasize that Classical Physics is principally different from Quantum Physics that describes quantum objects, which have four-momenta only. Classical Physics is dealing with ensembles of quantum objects! The present paper discusses the Basic Notions of Classical Physics considering a principally different cosmological model WUM, which is, in fact, a Paradigm Shift for Cosmology. WUM is a natural continuation of Classical Physics, and it can already serve as a basis for a New Cosmology proposed by Paul Dirac in 1937.展开更多
The China-proposed Global Civilization Initiative has introduced a novel cultural-coexistence framework transcending notions of conflict like the"clash of civilizations"that too often shapes Western diplomacy.

This paper will report the results of a study into 64 high school English teachers＇ beliefs about language learning and their instructional practices, with a focus on two of them. A questionnaire was developed on the basis of major tenets of second language learning and administered to the 64 participants. In addition, classroom observations and interviews were employed to explore the two focal teachers＇ beliefs and their actual classroom instruction practices. Results show both consistencies and inconsistencies between the participants＇ beliefs and major SLA notions and between the two focal participants＇ beliefs and their classroom practices.展开更多
