Of Rawls's two principles of justice only the second has received attention from economists. The second principle is concerned with the social and economic conditions in a just society. The first principle, however, has largely been neglected. It claims, that all people in society should have equal basic liberties. In this paper Rawls's first principle is characterised in a freedom of choice framework. The analysis reveals conceptual problems of the Rawlsian approach to justice.

We have studied the bifurcations in a three-dimensional incompressible magnetofluid with periodic boundary conditions and an external forcing of the Arnold-Beltrami-Childress (ABC) type. Bifurcation-analysis techniques have been applied to explore the qualitative behavior of solution branches. Due to the symmetry of the forcing, the equations are equivariant with respect to a group of transformations isomorphic to the octahedral group, and we have paid special attention to symmetry-breaking effects. As the Reynolds number is increased, the primary nonmagnetic steady state, the ABC flow, loses its stability to a periodic magnetic state, showing the appearance of a generic dynamo effect; the critical value of the Reynolds number for the instability of the ABC flow is decreased compared to the purely hydrodynamic case. The bifurcating magnetic branch in turn is subject to secondary, symmetry-breaking bifurcations. We have traced periodic and quasi- periodic branches until they end up in chaotic states. In particular detail we have analyzed the subgroup symmetries of the bifurcating periodic branches, which are closely related to the spatial structure of the magnetic field.
The value concept of traditional resource economics is welfare. Therefore, sustainability of welfare is often taken to characterise our obligations to future generations. This paper argues that this view is inappropriate because it leaves no room for future generations autonomy. Future generations should be free to make their own decisions. Consequently freedom of choice is the appropriate value concept on which resource economics should be based. The concept of sustainability receives a new interpretation. Sustainability is a principle of intertemporal distributive justice which requires equitable opportunities across generations.
We have shown that the two-dimensional complex Ginzburg-Landau equation exhibits supertransient chaos in a certain parameter range. Using numerical methods this behavior is found near the transition line separating frozen spiral solutions from turbulence. Supertransient chaos seems to be a common phenomenon in extended spatiotemporal systems. These supertransients are characterized by an average transient lifetime which depends exponentially on the size of the system and are due to an underlying nonattracting chaotic set.
