Differentiated responsibilities and prosocial behaviour in climate change mitigation.

A characteristic feature of the global climate change dilemma is interdependence between the underlying economic development that drives anthropogenic climate change-typically modelled as a common pool resource dilemma-and the subsequent dilemma arising from the need to mitigate the negative effects of climate change, often modelled as a public goods dilemma. In other words, in a carbon-based economy, causal responsibility for climate change is a byproduct of economic development, and is therefore endogenous to it. To capture this endogeneity, we combine these two dilemmas into a 'compound climate dilemma' and conduct a series of incentivized experiments in the United States and China to test its implications for cooperation and prosocial behaviour.

Diderot: a Domain-Specific Language for Portable Parallel Scientific Visualization and Image Analysis.

Many algorithms for scientific visualization and image analysis are rooted in the world of continuous scalar, vector, and tensor fields, but are programmed in low-level languages and libraries that obscure their mathematical foundations. Diderot is a parallel domain-specific language that is designed to bridge this semantic gap by providing the programmer with a high-level, mathematical programming notation that allows direct expression of mathematical concepts in code. Furthermore, Diderot provides parallel performance that takes advantage of modern multicore processors and GPUs.
