    World Wide Views on Global Warming was the first ever global-scale citizen deliberation process, held on 25-26 September 2009 and involving approximately 4,000 citizens in 38 countries. WWViews sought to provide citizens with a voice in the 2009 UN Climate Summit in Copenhagen (COP15) by engaging them in a deliberative process about global political positions on climate change. The process produced clear, comparable results across all participating countries that were given to COP15 negotiators. The Danish Government agencies, the Danish Board of Technology and the Danish Cultural Institute, initiated the global process. Organisers in each participating country ran events using the same standardised process. The University of Technology Sydney, the organisers of the Australian WWViews event, paid special attention to several elements of the process to maximise participation and impact within the local context. This paper outlines the standardised global process used for this deliberative event and describes and reflects upon the tailored approaches developed for Australia. It examines in detail the objectives, processes and outcomes of recruiting and supporting participants and recruiting, training and coordinating facilitators, communications and dissemination of results and specific features of the Australian event. It includes the organisers' reflections on success factors, challenges and surprises, as well as feedback from facilitators and participants. This paper concludes with a number of critical questions arising from the Australian experience of World Wide Views on Global Warming that are pertinent for practitioners designing other deliberative forums and particularly anyone concerned about future prospects for global deliberative democracy.

    Nonlinearity-assisted quantum tunneling in a matter-wave interferometer

    Full text link
    We investigate the {\em nonlinearity-assisted quantum tunneling} and formation of nonlinear collective excitations in a matter-wave interferometer, which is realised by the adiabatic transformation of a double-well potential into a single-well harmonic trap. In contrast to the linear quantum tunneling induced by the crossing (or avoided crossing) of neighbouring energy levels, the quantum tunneling between different nonlinear eigenstates is assisted by the nonlinear mean-field interaction. When the barrier between the wells decreases, the mean-field interaction aids quantum tunneling between the ground and excited nonlinear eigenstates. The resulting {\em non-adiabatic evolution} depends on the input states. The tunneling process leads to the generation of dark solitons, and the number of the generated dark solitons is highly sensitive to the matter-wave nonlinearity. The results of the numerical simulations of the matter-wave dynamics are successfully interpreted with a coupled-mode theory for multiple nonlinear eigenstates.Comment: 11 pages, 6 figures, accept for publication in J.
