this article discuss about public policy implementation for cultural space in iran. we want to design a model for implementing cultural policy. and will explain the factors of the model and the relations between them. then we will compare the proposed model with the other famous models on the word. the proposed model created with the qualitative methodology which is grounded theory (gt). with p...

Computational agents often need to learn policies that involve many control variables, e.g., a robot needs to control several joints simultaneously. Learning a policy with a high number of parameters, however, usually requires a large number of training samples. We introduce a reinforcement learning method for sampleefficient policy search that exploits correlations between control variables. S...

Decentralisation continues to re-appear in health system reform across the world. Evaluation of these reforms reveals how research on decentralisation continues to evolve. In this paper, we examine the theoretical foundations and empirical references which underpin current approaches to studying decentralisation in health systems.

Several ``Paretian'' welfare rules are equivalent when policymakers know agents' characteristics, e.g., a policy is optimal if (a) any other policy making someone better o ̈ harms some agent, or (b) it is the maximum of some social welfare function. This paper extends these and other rules to environments where policymakers have a probability distribution over a state space of possible models. U...
