We tested the hypothesis that the effect of forest basal area on tree growth interacts with macro-ecological gradients of primary productivity, using a large dataset of eucalypt tree growth collected across temperate and sub- tropical mesic Australia. To do this, we derived an index of inter-tree competition based on stand basal area (stand BA) relative to the climatically determined potential ...

BACKGROUND Emerging approaches to building more efficient and effective behavioral interventions are becoming more widely available. The current paper provides an empirical example of the use of the engineering-inspired multiphase optimization strategy (MOST) to build a remotely delivered responsive parenting intervention to prevent obesity among children of low-income mothers with and without ...

Because quality is privately observed, by the standard adverse-selection logic, the market can at best o¤er a price that re‡ects the average quality of ideas sold. This gives the holders of above-average-quality ideas the incentive to spin o¤. We show that only wor...
