Exploring the Dynamics of Incongruent Beliefs about Women and Leaders

People tend to have similar beliefs about leaders and men but dissimilar beliefs about leaders and women. A decrease in this perceived incongruity between beliefs about women and leaders might follow from perceived changes in either or both of these stereotypes. In two experiments we investigated the dynamics of this stereotype incongruity by examining cross‐temporal perceptions of change in women's roles and leadership demands. In Experiment 1 , participants judged a target group (leaders, men, or women) in a specified year in the past, the present and the future with regard to gender‐stereotypic traits. In Experiment 2 , participants evaluated the same target groups in a future society in which the role distribution between the sexes was described as traditional, same‐as‐today, or equal. Altogether our findings indicate that the perceived incongruity between the leader stereotype and the female stereotype is a dynamic phenomenon. Participants' beliefs indicated erosion of the perceived incongruity between leaders and women because of a perceived change in women's roles. We discuss the implications of these beliefs for future social change.     

Exploring Antecedents of Charitable Giving and Their Impact on Subjective Well-Being in Singapore

There is a declining number of donors and increasing number of charities competing for donations in Singapore. In this study we explore the values and attitudes (i.e. empathy, individualism and materialism) associated with donation behaviour and their consequences on the donor’s subjective well-being among 226 Singaporeans from a cross-section of society. We found individuals who value warm relationships with others are more likely to have an empathetic attitude and donate money to charities. However, we did not find a relationship between individualism and donation behaviour nor materialism and donation behaviour. Moreover, helping those in need (donation behaviour) did not influence the donor’s subjective well-being. The theoretical and managerial implications are discussed and suggestions for future research provided.     

Analysis and Management of Periodic Review,Order‐Up‐To Level Inventory Systems with Order Crossover

In this article, we investigate the (R, S) periodic review, order‐up‐to level inventory control system with stochastic demand and variable leadtimes. Variable leadtimes can lead to order crossover, in which some orders arrive out of sequence. Most theoretical studies of order‐up‐to inventory systems under variable leadtimes assume that crossovers do not occur and, in so doing, overestimate the standard deviation of the realized leadtime distribution and prescribe policies that can inflate inventory costs. We develop a new analytic model of the expected costs associated with this system, making use of a novel approximation of the realized (reduced) leadtime standard deviation resulting from order crossovers. Extensive experimentation through simulation shows that our model closely approximates the true expected cost and can be used to find values of R and S that provide an expected cost close to the minimum cost. Taking account of, as opposed to ignoring, crossovers leads, on average, to substantial improvements in accuracy and significant cost reductions. Our results are particularly useful for managers seeking to reduce inventory costs in supply chains with variable leadtimes.
