Larry V. Hedges, PhDnNorthwestern University n10/16/2018nnRandomized trials provide the gold standard of internal validity for making causal inferences about the effects of interventions.However, randomized trials are seldom conducted using probability samples that might provide the same gold standard of generalizability (external validity). I will discuss methods to quantify and improve the generalizability of findings from randomized trials conducted to inform policy and illustrate these ide

The amount and distribution of plastic pollution in the deep ocean dictates the risks that plastic may pose to living organisms, and also has implications for effective mitigation and remediation. In this study, we provide one of the first estimates of the global ocean floor reservoir of plastic pollut")
