In 2008, Chile implemented a targeted voucher program that increased voucher values for disadvantaged students at participating schools by approximately 50%. Although disadvantaged students made substantial fourth grade test score gains that other studies have attributed to the program, our...

Metal- and halide-free catalyst DABCO·HSac, i.e. the binary adduct of 1,4-diazabicyclo[2.2.2]octane (DABCO) and saccharin (HSac), in an ionic pair structure of DABCO-H⁺·Sac⁻ is shown mild and efficient in promoting the cycloaddition of CO 2 into epoxides (CCE) reactions. Under...

In this paper, we study the problem of dynamic convex risk measures via reflected backward stochastic differential equations with time delayed generators (RBSDEs with time delayed generators, in short). Under some assumptions on the generators of the equations, we prove that the RBSDEs with a...

It is vital for selectively preferential dechlorination by visible-light photocatalysis to eliminate high-risk 2-chlorophenol (2-CP) contaminant. However, selective adsorption and efficient charge separation remain challenging. Herein, ultrathin (100) facet-exposed Bi 2 MoO 6 (BMO) nanosheets...
