In the framework of ethical social choice theory, sustainability is justified by Efficiency and Equity as ethical axioms. These axioms correspond to the Suppes-Sen Grading principle. In technologies that are productive in a certain sense, the set of Suppes-Sen maximal utility paths is shown to equal the set of non-decreasing and efficient paths. Since any such path is sustainable, Efficiency an...

The two dimensional version of the Sen connection for spinors and tensors on spacelike 2-surfaces is constructed. A complex metric γ AB on the spin spaces is found which characterizes both the algebraic and extrinsic geometrical properties of the 2-surface $. The curvature of the two dimensional Sen operator ∆ e is the pull back to $ of the anti-self-dual part of the spacetime curvature while i...

In this paper we present a framework to be used for evaluation of Information and Communication Technology for Development (ICT4D) projects. The framework is based on Sen ́s notion of development as freedom where human capabilities and functionings are seen as key aspects to development. Sen ́s capability approach presents an alternative way of seeing and evaluating development (alternative to mo...
