Spekkens has introduced a toy theory (Spekkens in Phys. Rev. A 75(3):032110, 2007) in order to argue for an epistemic view of quantum states. I describe a notation for the theory (excluding certain joint measurements) which makes its similarities and differences with the quantum mechanics of stabilizer states clear. Given an application of the qubit stabilizer formalism, it is often entirely straightforward to construct an analogous application of the notation to the toy theory. This assists calculations within the toy theory, (...) for example of the number of possible states and transformations, and enables superpositions to be defined for composite systems. (shrink)

In the light of Markus’s notion of the decent society, this contribution examines the challenges facing public intellectuals in Australia’s contemporary political public sphere. It observes, firstly, that Australia has a distinctly Benthamite political culture that listens more to bureaucratic solutions than to metaphysics, history and arguments grounded in human rights. It explains, secondly, how public opinion gives voice to underlying norms and should thus be treated as the starting point for intellectual activism. Thirdly, the article looks into confusion on (...) the criteria for political deliberation in contemporary Australia. Consideration is then given to the growing constraints imposed on public intellectuals through various new forms of censorship and closure. The conclusion uses the gathering debates on adjustment to climate change to illustrate how public intellectual activism can break new ground. (shrink)

In this century Australia has enjoyed the highest per capita incomes and probably the most equal distribution of income of any nation in the world. Australia has been a lighthouse social democracy. We assess the impact of the vigorous liberal economic reforms of the 1980s on economic management and steering, social integration and cohesion, on the public sector, on civil society and the public sphere. We see that the reforms have been ideologically driven and that they have negatively affected the (...) distribution of income, the deliberative capacity of the policy apparatus, and the unique institutional features of social democracy in Australia.
