Following the tragic loss of Columbia in early 2003, executives at the National Aeronautics and Space Administration implemented a simulation‐based training program to facilitate the development of the Space Shuttle Mission Management Team (MMT). This article discusses the findings from an evaluation of two multi‐day simulation training events. The results of both evaluations suggested that MMT members: (1) possessed shared beliefs in their joint capabilities to execute their corecompetencies; (2) were motivated and ready for their Return to Flight mission; (3) achieved targeted levels of team performance during the simulations; and (4) were both satisfied with the training program and found it useful for facilitating performance improvements. This note concludes with a discussion of lessons learned.  相似文献

This study reports experiments that examine behavior under team production and a piece rate. In the experiments, participants complete a forecasting task and are rewarded based on the accuracy of their forecasts. In the piece‐rate condition, participants are paid based on their own performance, whereas the team‐production condition rewards participants based on the average performance of the team. Overall, there is no statistically significant difference in performance between the conditions. However, this result masks important differences in the behavior of men and women across the conditions. Men in the team‐production condition increase their performance relative to men in the piece‐rate condition. However, this gap in male performances across conditions diminishes over the course of the experiment. In contrast, women in the team‐production condition show significantly lower performance than the women in the piece rate. As a consequence of these differences, men in the team‐production condition show significantly better performance than women in the team‐production condition. We also find evidence that men show stronger performance when they are in teams with a larger variation in skill level. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

Y. V. Veld‐Merkoulova and F. A. de Roon (2003) adopted an encompassing model to demonstrate their linear yield assumption on the term structure of futures prices gains more empirical support than the linear price assumption proposed by A. Neuberger (1999). This comment points out the test procedure adopted is inappropriate and proposes an alternative non‐nested hypothesis testing method. Using the crude oil data, we find that the linear price assumption outperforms the linear yield assumption but is inferior to a generalized version of the linear yield assumption. © 2004 Wiley Periodicals, Inc.

Multiple delivery specifications exist on nearly all commodity futures contracts. Sellers typically are allowed to deliver any of several grades of the underlying commodity and at any of several locations. On the delivery day, the futures price as such needs not converge to the spot price of the par‐delivery grade at the par‐delivery location, thereby imposing an additional delivery risk on hedgers. This article derives the optimal hedging strategy for a risk‐averse hedger in the presence of delivery risk. In particular, it is shown that the hedger optimally uses options on futures for hedging purposes. This article provides a rationale for the hedging role of options when futures markets allow for multiple delivery specifications. © 2002 Wiley Periodicals, Inc.

In some economies, workers are compensated for their commuting costs to the workplace. The spatial structure of an urban area is analyzed comparing a transport cost compensated system to one where expenses are borne by workers. Profit maximizing behavior by firms results in lower wages being paid in the city where transport costs are compensated. It is shown that worker renters achieve a higher level of utility in the area where transport costs are not compensated. Numerical examples are constructed using a range of parameter values which yields measures of the increase in spatial size of the city where transport costs are compensated. The loss in welfare is also evaluated.  相似文献
