Seismic Performance Evaluation of Highway Bridges under Scour and Chloride Ion Corrosion

open access: yesApplied Sciences, 2022
Cross-river bridges located in seismically active areas are exposed to two major natural hazards, namely earthquakes and flooding. As the scour depth increases, more parts of the bridge substructure will inevitably be exposed to unfavorable conditions ...

THE SUBSTITUTABILITY OF REINFORCERS [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 1993
Substitutability is a construct borrowed from microeconomics that describes a continuum of possible interactions among the reinforcers in a given situation. Highly substitutable reinforcers, which occupy one end of the continuum, are readily traded for each other due to their functional similarity.
