Literature reports different effects of mood on measures of consumer behavior. Either mood congruence or mood regulation theories serve to explain these effects, though the latter theory is perhaps more sophisticated. This research goes a step further: in a sequence of four studies, the authors...

Emergency supply chain management is often in the focal point of public scrutiny. Expected cost minimization may result in unacceptable high shortage for scenarios with small probabilities that is hardly tolerated by the public. To decrease the loss for the worst-case scenario, the min–max...

Consider testing for equality variances in a one-way analysis of variance. Levene's test is the usual F-test for equality of means computed on psuedo-observations, which one defines as the absolute deviations of the data points from an estimate of the group 'center'. We show that,...

Methods for detecting influential observations for the Weibull model fit to censored data are discussed. These methods include: one-step deletion diagnostics, influence functions and curvature diagnostics. Results indicate that the curvature diagnostics may be helpful in detecting masking.
