和谐边疆构建下的宗教渗透问题研究——基于对云南跨境民族的田野调查

通过对云南跨境民族地区的田野调查,该区域宗教渗透不仅没有停止,反而呈现出多样性、隐蔽性等特点。宗教渗透对跨境民族的国家政治认同等造成了严重破坏,对云南边疆社会的稳定构成了较大的威胁,成为了云南边疆地区非传统安全问题中最敏感、最复杂、最难解决的问题之一。抵御宗教渗透不仅要完善政府宗教管理能力、改善经济条件等,更要调动作为文化主体者的跨境民族自身的"文化自觉",以主动抵御宗教渗透。只有如此才是最有效的抵御宗教渗透举措,才最终有利于和谐边疆的构建。     

On the output function in a Ginsburg’s machine

We give the form of the output function in Ginsburg’s machine in which the input and output dictionaries are abelian groups and the transition function is of a special form.     

Detecting nonclassicality of light via Lieb's concavity

Nonclassical light states are important for both conceptual and practical reasons: they are basic ingredients in testing and exploring quantum foundations, and are crucial resources in quantum technologies. Various useful criteria have been developed to detect nonclassicality in the literature, and several meaningful measures of nonclassicality have been introduced and measured experimentally. In this work, by use of a non-Hermitian generalization of the Wigner-Yanase-Dyson skew information and playing with operator ordering in evaluating average photon number, we develop a novel family of criteria for detecting nonclassicality of light based on Lieb's concavity, which is a deep and powerful result concerning interaction between quantum states and observables. We elucidate the information-theoretic as well as the physical meaning of the criteria, and illustrate their effectiveness in capturing and quantifying nonclassicality of various important light states.
