Management meted out punishment to enforce rules and encourage adherence. However, the effectiveness depended on how the employees perceive and interpret the policy. This study tested the effect of reducing individual lateness in a plastic factory. Field experiment was conducted to test the...

Some sharp inequalities of Grüss type for sequences of vectors in real or complex normed linear spaces are obtained. Applications for the discrete Fourier and Mellin transform are given. Estimates for polynomials with coe cients in normed spaces are provided as well
