International Law Teaching in China: Engaging in a Pedagogical Reform or Embracing Professionalism and Internationalization?
As international law is becoming increasingly relevant to the rising China, serious problems have been found to cluster in the international law teaching in China. Since its introduction, the development of international law in China has been plagued by the love-and-hatred attitudes of the Chinese regimes in succession towards it. What Chinese law schools and beyond are lacking is a true professionalism that demands an estrangement from political reality and internationalization that calls for retrench of the pedagogical approaches. This article is intended to contribute to the understanding of the landscape of international law teaching in this rising country as it faces challenges
Distributed Optimal Rate-Reliability-Lifetime Tradeoff in Wireless Sensor Networks
The transmission rate, delivery reliability and network lifetime are three
fundamental but conflicting design objectives in energy-constrained wireless
sensor networks. In this paper, we address the optimal
rate-reliability-lifetime tradeoff with link capacity constraint, reliability
constraint and energy constraint. By introducing the weight parameters, we
combine the objectives at rate, reliability, and lifetime into a single
objective to characterize the tradeoff among them. However, the optimization
formulation of the rate-reliability-reliability tradeoff is neither separable
nor convex. Through a series of transformations, a separable and convex problem
is derived, and an efficient distributed Subgradient Dual Decomposition
algorithm (SDD) is proposed. Numerical examples confirm its convergence. Also,
numerical examples investigate the impact of weight parameters on the rate
utility, reliability utility and network lifetime, which provide a guidance to
properly set the value of weight parameters for a desired performance of WSNs
according to the realistic application's requirements.Comment: 27 pages, 10 figure
