Is there Space for "Genuine Autonomy" for Tibetan Areas in the PRC's System of Nationalities Regional Autonomy?

This article considers whether room exists within the current system of nationalities regional autonomy (NRA) in China to accommodate Tibetan aspirations for "genuine autonomy" under the People's Republic of China (PRC) sovereignty. It examines the legal framework for NRA in China, as well as Chinese government policy and practice toward autonomous areas, in terms of the limitations and possibilities they imply for realizing Tibetan aspirations for autonomy, highlighting specific areas of concern, opportunities and constraints. It explores the development of political and legal approaches toward autonomy since the 1930s, the nature of the current framework and how recent legal and political developments interact with that framework. It looks at options for autonomy under the Chinese Constitution and national legislation, particularly the self-government of nationality (minority) autonomous areas as well as Article 31 of the Constitution which has provided the basis for the establishment of special administrative regions (SARs). Since autonomous areas also exercise the general powers of local governments in the PRC, it describes the general system of local government at the provincial and lower administrative levels. The article examines the practical implementation and operation of minority autonomy and SARs including the apparent gap between law and practice. In particular, special attention is paid to the role of the Chinese Communist Party and its officials which have a significant impact on the exercise of state powers. It concludes that there are formidable obstacles to the autonomy that Tibetans seek in order to preserve their culture, values and identity. © Koninklijke Brill NV, Leiden, 2010.postprin

Nonlinear dynamics and transport driven by energetic particle instabilities using a gyro-Landau closure model

Energetic particle (EP) destabilized Alfvén eigenmode (AE) instabilities are simulated for a DIII-D experimental case with a pulsed neutral beam using a gyro-Landau moments model which introduces EP phase-mixing effects through closure relations. This provides a computationally efficient reduced model which is applied here in the nonlinear regime over timescales that would be difficult to address with more complete models. The long timescale nonlinear evolution and related collective transport losses are examined including the effects of zonal flow/current generation, nonlinear energy cascades, and EP profile flattening. The model predicts frequencies and mode structures that are consistent with experimental observations. These calculations address issues that have not been considered in previous modelling: The EP critical gradient profile evolution in the presence of zonal flows/currents, and the dynamical nature of the saturated state. A strong level of intermittency is present in the predicted instability-driven transport; this is connected to the zonal flow growth and decay cycles and nonlinear energy transfers. Simulation of intermittent AE-enhanced EP transport will be an important issue for the protection of plasma facing components in the next generation of fusion devices.This material is based upon work supported by the US Department of Energy, Office of Science using the DIII-D National Fusion Facility, a DOE Office of Science user facility, under Awards DE-AC05-00OR22725, DE-FC02-04ER54698, and the US DOE SciDAC ISEP Center.

Analysis of the ECH effect on the EPM/AEs stability in Heliotron J plasma using a Landau closure model

The aim of the present study is to analyze the effect of the electron cyclotron heating (ECH) on the linear stability of Alfven Eigenmodes (AE) and energetic particle modes (EPM) triggered by energetic ions in Heliotron J plasma. The analysis is performed using the FAR3d code that solves a reduced MHD model to describe the thermal plasma coupled with a gyrofluid model for the energetic particles (EP) species. The simulations reproduce the AE/EPM stability trends observed in the experiments as the electron temperature (Te) increases, modifying the thermal plasma beta, EP beta and EP slowing down time. Particularly, the n/m=1/2 EPM and 2/4 Global AE (GAE) are stabilized in the low bumpiness (LB) configuration due to an enhancement of the continuum, Finite Larmor radius (FLR) and e-i Landau damping effects as the thermal beta increases. On the other hand, a larger ECH injection power cannot stabilize the AE/EPM in Medium (MB) and High bumpiness (HB) configurations because the damping effects are weaker compared to the LB case, unable to balance the further destabilization induced by an enhanced EP resonance as the EP slowing down time and EP beta increases with T
