The completeness proofs of [ Huang and Valtorta, 2006 ] and [ Shpitser and Pearl, 2006 ] and the graphi- cal criteria of [ Tian and Shpitser, 2010 ] have laid this identification problem to rest. Recent explorations un- veil the usefulness of the do -calculus in three addi- tional areas: mediation analysis [ Pearl, 2012 ] , trans- portability [ Pearl and Bareinboim, 2011 ] and meta- synthesis. Meta-synthesis (freshly coined) is the task of fusing empirical results from several diverse stud- ies, conducted on heterogeneous populations and un- der different conditions, so as to synthesize an esti- mate of a causal relation in some target environment, potentially different from those under study. The talk surveys these results with emphasis on the challenges posed by meta-synthesis. For background material, see 〈 http://bayes.cs.ucla.edu/csl http://bayes.cs.ucla.edu/csl papers.html 〉
