A flexibility intervention to reduce the incidence and severity of joint injuries among municipal firefighters.

The present study of 469 municipal firefighters examined the effect of flexibility training on the incidence and severity of joint injuries. Both flexibility measures and costs (lost time and medical care costs) were investigated in this study. Significant differences were found in flexibility scores of the experimental and control subjects with overall flexibility increased in the experimental group. Although incidence of injury was not significantly different for the experimental and control groups, injuries sustained by the experimental group resulted in significantly less lost time costs. Findings indicate that the flexibility training program had a beneficial effect on reducing the severity and costs of joint injuries in this firefighter population.

Effects of single or multiple choice trials per session on drug discrimination performance.

Drug discrimination procedures typically provide for multiple choice opportunities per training session. This practice allows non-drug cues (presence or absence of reinforcement) to mediate choice behavior during that portion of the session following the initial choice. In this experiment, rats were trained to discriminate 1.0 mg/kg cyclazocine from saline using a novel procedure that employed a single-choice trial per training session. Drug discrimination acquisition and generalization were compared to those of rats given discrimination training with 30 choice trials per session. The one-trial procedure yielded stable and reliable acquisition but more slowly than did the multiple trials procedure. The one-trial procedure produced longer first trial choice latencies and enhanced the tendency for subjects to respond on both choice levers during the first trial. The cyclazocine generalization functions were comparable, but the one-trial subjects more often responded on both choice levers, particularly when administered intermediate test doses of cyclazocine. Control of choice behavior by the reinforcer cue was evaluated on a mid-session cue reversal test. Multiple-trial subjects persisted in responding on the saline level following a mid-session injection of cyclazocine, whereas one-trial subjects shifted to the cyclazocine-appropriate lever.

Drug discrimination training with a single choice trial per session.

All drug discrimination procedures share in common the practice of providing for multiple choice opportunities per training session. This practice allows nondrug cues (presence or absence of reinforcement) to mediate choice behavior during that portion of the session following the initial choice. Investigators who have acknowledged this problem typically use only first-trial choice performance to evaluate discriminative control by the drug cue, and consider additional choice training following the delivery or nondelivery of the first reinforcer to be facilitatory in establishing drug-mediated discriminative control. In this experiment, rats were trained to discriminate 4.0 mg/kg morphine from saline in a novel procedure that employed a single choice trial per training session. Choice performance was characterized during discrimination acquisition and in subsequent stimulus generalization testing. The results indicated that when all reinforcers are made contingent on correct performance during a single choice trial, rapid and stable control of drug-mediated choice behavior, is observed. In addition, the results demonstrated that additional choice training following the delivery or nondelivery of the first reinforcer is not a necessary antecedent toward establishing drug-mediated discriminative control.

Using focus group methodology in nursing.

BACKGROUND: The need to obtain quality data in a cost-efficient manner spawned an exploration of research methods. The value of focus group methodology for multiple roles in nursing became evident. METHOD: This article describes the purpose, process, and application of focus group methodology for nursing continuing education. RESULTS: Ideas for use of focus group methodology in nursing continuing education are suggested. CONCLUSION: Focus group methodology can enhance the work of nurses in continuing education roles.
