Four different programmes involving trainees, instructors and workplace supervisors participated in the investigation. Results indicated that the transfer of learning occurs through various life roles that adults enact while participating in the programme; the Essential Skills of computer literacy, oral communication, and continuous learning are the guideposts for transfer and the time/role model of learning transfer helps explain the different instructional strategies used in the classroom and the workplace. The findings shed some light on how sociocultural learning develops in adult literacy groups destined for the workforce and the importance of the tri‐partnership of the instructor, trainee and workplace supervisor.

Previous investigators have developed protocols for reliable MART-1 immunostaining of frozen sections, but these protocols are time-consuming. The objective was to report a rapid 20-minute MART-1 immunostaining protocol for frozen sections. The protocol was utilized on 30 melanomas treated with Mohs micrographic surgery. The stain clearly highlighted normal background melanocytes, as well as melanocytic hyperplasia and malignant melanoma. The 20-minute protocol provides a rapid and reliable method for immunostaining of malignant melanoma. The availability of more rapid immunostaining methods improves efficiency of the Mohs laboratory and significantly reduces patient and physician waiting time. The authors have indicated no significant interest with commercial supporters.
