The resurgence and asymptotic of an ideal in a polynomial ring are two statistics which measure the relationship between its regular symbolic powers. We address aspects can be studied via resurgence. First, we show that if has Noetherian Rees algebra then is rational. Second, derive bounds on given single known containment power. From these recover extend criteria for to strictly less than big ...

Resurgence is the relapse of an extinguished instrumental behavior that can occur when an alternative behavior that was introduced to replace it is itself extinguished. In a typical resurgence experiment, rats are trained to make a response (R1) for food reinforcers. In a second phase, responses on R1 are no longer reinforced, but a new response (R2) is introduced and responses on it are reinfo...

Two experiments were conducted to identify the conditions likely to produce resurgence among adult human participants. The preparation was a simulated caregiving context, wherein a recorded infant cry sounded and was terminated contingent upon targeted caregiving responses. Results of Experiment 1 demonstrated resurgence with human participants in this negative reinforcement preparation. Result...
