Earplugs is a program to allow predictive evaluation of earplugs and earmuffs. Written in Basic for the Apple II+, it is translatable into all other versions of Basic. The program allows the user to compare the attenuation capabilities of any earplug versus the environmental octave band analysis for the workplace in question. This version of the program provides a plot of the results.

A 35-item multiple choice inventory to assess inpatient staff's knowledge of behavioral methods with children and adolescents is described. The instrument appears to possess satisfactory content validity for basic behavioral principles and good internal consistency and reliability. It appears useful for research and staff inservice educational assessment in inpatient treatment settings where a measure of this type in needed. The inventory may also be useful in identifying newly employed staff who may benefit from behavioral training before assuming direct services roles on inpatient wards.

The hypothesis that ethylene regulates prostrate stem growth was investigated using stolons of strawberry clover (Trifolium fragiferum L. var. Salina). Stolons became erect when treated with ethylene or 2-chloroethylphosphonic acid. Curvature was visibly detectable 2 hours after ethylene treatment, and subsequent stem elongation was rapid. Indoleacetic acid application to prostrate stolons caused only a small transitory curvature persisting less than 48 hours. Indoleacetic acid-stimulated curvature was accompanied by an increase in ethylene evolution. When stolon curvature was induced by placing strawberry clover plants in darkness or by applying gibberellic acid, ethylene production did not parallel stolon curvature.
