The requirements of pretransfusion testing have undergone repeated modification, and those of the type and screen policy are currently the most widely accepted to be standard. The type and screen test policy, together with the abbreviated crossmatch procedure, was implemented in the United Christian Hospital in January 1997. This paper discusses the impact of the type and screen test policy on ...

We describe an iterative procedure for optimizing policies, with guaranteed monotonic improvement. By making several approximations to the theoretically-justified procedure, we develop a practical algorithm, called Trust Region Policy Optimization (TRPO). This algorithm is similar to natural policy gradient methods and is effective for optimizing large nonlinear policies such as neural networks...

prospective studies of the potential health consequences of trade and investment treaties, such as the trans-pacific partnership, are critical. these studies can make visible to trade policy-makers the potential negative impacts associated to such treaties and can influence the outcomes of such negotiations. however, few researchers have examined retrospectively the consequences of trade agreem...
