“…They followed Kerr and Jermier (1978) to identify potential substitutes by drawing eclectically from theories of individual differences, task characteristics, and organization structure.

In order to replicate prior research showing their non-significant effects, these substitutes were measured and tested in the present study, but no dependable moderating effects were found (details available from the authors).…”
