Discounting and Consumption Over an Uncertain Horizon: Draw-Down Plans for Family Trusts [PDF]
Individuals, endowments and trusts face uncertain lifetimes. When the planning horizon of an entity is stochastic and Pareto distributed, hyperbolic discounting and time-varying consumption rates are optimal. We derive expressions for the optimal rate of

The effect of gradual extinction training on the renewal of electrodermal conditional responses
Extinction, the repeated presentation of a conditional stimulus (CS) without the unconditional stimulus (US), is the standard paradigm to reduce conditional responding acquired by the repeated pairing of CS and US in acquisition.

RE-IGNITION OF MULTI-SPECIES SOOT CLOUDS IN BUILDING FIRES [PDF]
, 2007 The re-ignition potential of multi-species soot clouds in building fires were investigated based on their extinction characteristics. The investigation was carried out theoretically using an adaptation of Semenov’s thermal explosion theory.
