American Christianity, however, is imbued in a modem---even pre-modern--paradigm. As a result, many contemporary religious leaders find it difficult to communicate with their postmodern constituents, as evidenced by declining attendance rates and religious affiliation. The present study explores this dilemma by offering potential implications for contemporary religious leaders to communicate more effectively with emerging/emergent generation（s）. The author begins this exploration, first, by outlining the philosophical tenants of postmodemism： its epistemological, ontological, and axiological assumptions. Second, the author delineates several key characteristics of postmodern religious communication. Next, the author offers three practical implications for organizational leaders： （1） increased use of personal narrative, （2） removal of hierarchal boundary structures, and （3） increased awareness and appreciation for divergent perspectives. The author concludes this study with directions for future research.展开更多

The proposed algorithm adopts an improved distributed common radio resource management（DCRRM） model which can reduce the signaling overhead sufficiently. This scheme can be divided into two phases. In the first phase, candidate network set of each user is obtained according to the received signal strength（RSS）. And the simple additive weighted（SAW） method is employed to determine the active network set. In the second phase, the utility optimization problem is formulated by linear combining of the video communication satisfaction model, cost model and energy efficiency model. And finding the optimal bandwidth allocation scheme with Lagrange multiplier method and Karush-Kuhn-Tucker（KKT） conditions. Simulation results show that the proposed algorithm promotes the network load performances and guarantees that users obtain the best joint utility under current situation.展开更多

It demonstrates how a network of distributed services, resource sharing, co-investment, and access integration contributes to sustainable library development.展开更多

文摘Comprehensively developing the ideological and political curriculum in colleges and universities is not only a strategic measure to implement the fundamental task of moral education,but also a necessary path to deepen curriculum reform from the perspective of“great ideological and political education”.Taking Business Negotiation and Management Communication(BNMC)—the core course for international trade and business administration majors at Central South University—as an example,this paper proposes the principles of ideological and political case-based teaching,and systematically integrates ideological and political elements with professional knowledge accordingly.Focusing on the teaching content of Chapters 2,3,and 7 of the textbook,it explores how to combine ideological and political cases with professional content in practical classroom scenarios.Finally,this paper summarizes the implementation of case-based ideological and political teaching in BNMC course and offers several reflective insights.
