An ABAB design was used to evaluate the effectiveness of an interdependent group contingency with randomized components to improve the transition behavior of middle school students identified with emotional and behavioral disorders (EBDs) served in an alternative educational setting. The intervention was implemented by one teacher with three classes of students, and the dependent variable was the percentage of students ready to begin class at the appropriate time. Data revealed significant improvements in student behavior, providing support for implementation of group contingencies for students with EBDs in alternative educational settings and an example of feasible procedures and data collection methods.

Transdermal absorption of lidocaine was determined by measuring plasma lidocaine concentrations following skin application of 5% lidocaine patches. Two lidocaine patches were placed on the ventral abdominal midline of seven dogs for 72 hours. Lidocaine was detectable in plasma 12 hours after patch application, and it reached steady-state concentrations between 24 and 48 hours.

This study compared anesthetic and cardiorespiratory effects of tiletamine-zolazepam-butorphanol (TT), tiletamine-zolazepam-butorphanol-medetomidine (TTD), and tiletamine-zolazepam-butorphanol-medetomidine with atipamezole reversal 1 hour after TTD administration in dogs. All dogs received glycopyrrolate. All drug combinations effectively induced anesthesia within 5 minutes after IM injection.
