Small sample behaviour of some nonparametric multi-sample location tests in the presence of dispersion differences

This paper describes the small and moderate sample behaviour of three studentized non-parametric statistics by Sen and a modified Wilcoxon statistic by Potthoff for testing the equality of location parameters in the presence of dispersion differences. Based on the agreement between the asymptotic and small sample distributions of the statistics as well as a comparison of their power under heteroscedasticity, the studentized Wilcoxon and the studentized Brown and Mood tests arc preferred in the two-sample and c-sample situations, respectively.     

E-procurement in the Greek food and drink industry: Drivers and impediments

Most empirical research on e-procurement has focused on large economies and technology-related industries, paying little attention to smaller economies and traditional industries. This paper addresses this gap by presenting a study on the state and development of e-procurement in the Greek food and drink industry, based on four case studies with some of the largest organisations in the industry. This study indicates that the uptake of e-procurement has been slow and reveals some important impediments, such as the uncertainty of the technology and its benefits, the lack of infrastructure and skills and the traditional nature of the industry. These results led to a series of findings, propositions for further investigation. The drivers and impediments to e-procurement have been classified into four different levels: global, country, industry and firm. Each of these levels requires a different approach to dealing with it, having implications for practitioners and policymakers.     

Hierarchical integration in production planning: Theory and practice

This paper discusses the issue of integrating various decision levels in hierarchical production planning systems. First the theory is briefly reviewed and then two case studies are presented. It is argued that it is not sufficient to have a good decision model at every level of the decision hierarchy. The different models should be carefully integrated. The potential problems resulting from a lack of integration are discussed. These problems are then illustrated in two case studies in order to be able to focus on actual managerial issues. It is shown how different decision levels supported by decision models were integrated in these two applications. Two important features are the crucial role of crossfunctional managerial committees in the integration process and the introduction of slack to avoid disaggregation problems.We do not claim to be exhaustive in presenting the problems related to integration nor do we claim that the solutions to the cases are the best possible ones. We do, however, hope that this paper motivates production managers to take a serious look at their hierarchical planning procedures.     

Can Shareholders Be at Rest after Adopting Clawback Provisions? Evidence from Stock Price Crash Risk

Using a propensity score matched sample and a difference‐in‐differences research design, we find that stock price crash risk increases after a firm voluntarily incorporates clawback provisions in executive officers' compensation contracts. This heightened crash risk is concentrated in adopters that increase upward real activities‐based earnings management and those that reduce the readability of 10‐K reports. Based on cross‐sectional analyses, we also find that the increased crash risk is more pronounced for adopters with high ex ante fraud risk, low‐ability managers, high CEO equity incentives, and low dedicated institutional ownership. Collectively, our results suggest that the clawback adoption per se does not curb managerial opportunism but rather induces managers to use alternative channels for concealing bad news, which may contribute to a greater stock price crash risk; and the increase in crash risk is more likely in cases where incentives are strong or monitoring is weak. Our results should be of interest to regulators and policymakers considering the effects of clawback adoption on the investing public.

The impact of mentoring quality on protégés' organization‐based self‐esteem and proactive behavior: The moderating role of traditionality

Based on self‐consistency theory, this study examined the relationship between mentoring quality as perceived by protégés and protégés' proactive behavior. It focused on the mediating role of organization‐based self‐esteem (OBSE) and the moderating role of traditionality. To examine these relationships, we administrated three‐wave surveys to 237 subordinate–supervisor dyads in a construction enterprise. The results of hierarchical linear modeling demonstrated that (a) mentoring quality and proactive behavior had a positive relationship; (b) OBSE mediated this relationship; and (c) traditionality strengthened both the relationship between mentoring quality and OBSE and the indirect effect of mentoring quality on proactive behavior via OBSE. Our findings have theoretical and practical implications for research on mentoring and proactive behavior.

Revenge Exacerbates the Effects of Interpersonal Problems on Mentors’ Emotional Exhaustion and Work‐Family Conflict: A Self‐Defeating Perspective

Drawing on conservation of resources theory, this study examined the link between negative mentoring experiences (i.e., interpersonal problems) perceived by mentors and their work‐family conflict (WFC) by focusing on the mediating role of emotional exhaustion and the moderating role of revenge. The results of a field survey of 187 mentors in China supported all of our hypotheses, indicating that interpersonal problems perceived by mentors were positively related to their WFC. This relationship was also found to be mediated by the mentors’ emotional exhaustion. In addition, revenge against protégés was found to moderate the main effect of interpersonal problems on emotional exhaustion and the indirect effect of interpersonal problems on WFC. Specifically, revenge exacerbated the positive relationship between interpersonal problems and emotional exhaustion. Further, emotional exhaustion mediated the indirect effect of interpersonal problems on WFC when the level of revenge was high, but not when it was low. The findings of this study provide insightful theoretical contributions and managerial implications that indicate new directions for research related to mentoring and work‐family relationships. © 2016 Wiley Periodicals, Inc.
