Social participation of children with an autism spectrum disorder (ASD) in natural environments can be enhanced by teaching them to communicate spontaneously, at least in situations where they have the motivation to access specific items or activities by controlling the amount of access for these stimuli. The purpose of this study was to determine if mand training, using a stimulus control transfer procedure would promote acquisition and generalization of mands for specific activities or objects evoked by motivating operations. Measurement variables included the frequency of motivation controlled (MO) versus multiply controlled mands during discrete trial training on a variety of verbal operants. Using a concurrent multiple baseline design across participants, visual analysis indicated that MO mands for out-of-view items increased substantially with generalization across targets, staff, and environments for three of the four participants. One participant did not respond to intervention to the same extent as others.

ABSTRACTConjugative transfer of plasmids in enterococci is promoted by intercellular communication using peptide pheromones. The regulatory mechanisms that control transfer have been extensively studiedin vitro. However, the complicated systems that regulate the spread of these plasmids did not evolve in the laboratory test tube, and remarkably little is known about this form of signaling in the intestinal tract, the primary niche of these organisms. Because the evolution ofEnterococcus faecalisstrains and their coresident pheromone-inducible plasmids, such as pCF10, have occurred in the gastrointestinal (GI) tract, it is important to consider the functions controlled by pheromones in light of this ecology. This review summarizes our current understanding of the pCF10-encoded pheromone response. We consider how selective pressures in the natural environment may have selected for the complex and very tightly regulated systems controlling conjugation, and we pay special attention to the ecology of enterococci and the pCF10 plasmid as a gut commensal. We summarize the results of recent studies of the pheromone response at the single-cell level, as well as those of the first experiments demonstrating a role for pheromone signaling in plasmid transfer and in GI tract competitive fitness. These results will serve as a foundation for furtherin vivostudies that could lead to novel interventions to reduce opportunistic infections and the spread of antibiotic resistance.

We constructed a spherical pendulum model to represent liquid sloshing in a cylindrical container due to the motions of a wheeled mobile robot (WMR). The model is used to design paths and acceleration patterns for the WMR based on the damping of sloshing. The path curvature radius and WMR acceleration pattern are determined using input shaping. A PD controller enables the WMR to trace the designed path. Maximum sloshing displacement is a constraint condition in control transfer. Simulations and experiments clarified the effectiveness of our method.
