Blest (2000) proposed a new nonparametric measure of correlation between two random variables. His coefficient, which is dissymmetric in its arguments, emphasizes discrepancies observed among the first ranks in the orderings induced by the variables. The authors derive the limiting distribution of Blest's index and suggest symmetric variants whose merits as statistics for testing independence are explored using asymptotic relative efficiency calculations and Monte Carlo simulations. 相似文献

Introducing strategic quality management 总被引:1,自引:0,他引:1
This paper introduces strategic total quality management (STQM) as an extension of total quality management (TQM). STQM is defined as a quality management philosophy that views quality from the overall performance of a firm. It defines quality as being driven by customer and environmental needs and looks to identify critical factors that will determine the survivability and competitiveness of a firm in the near future. A contrast between total quality assurance, total quality management and strategic total quality management is presented using ten principles of quality. The dimensions of STQM are also identified and defined and STQM transformation frameworks are presented to show the process of implementing STQM. The strategic cycle presented here is linked to the popular PDCA or Deming cycle. Furthermore, top management strategies and reasoning for this new focus and strategic targets are identified, grouped and discussed. 相似文献

This study builds on recent research on the external workforce by examining the effects of (1) temporary work (2) independent contracting, and (3) consulting on firm performance, considering the client firms’ tasks, the qualification requirements for carrying out these tasks, and its strategic context. The findings are based on a survey of 261 firms in the German manufacturing industry. At the operational level, the results indicate that the difficulty of the tasks to be performed by external workers influences their performance. Whilst temporary work and consulting are better suited for simple tasks with low qualification requirements, independent contracting increases firm performance when appointing individuals to perform complex tasks. At the strategic level we research effects by two strategic orientations; one generally increasing the internal innovation performance (innovation orientation), the other generally increasing the performance of external relationships (alliance orientation). The innovation orientation here reduces the negative effect of temporary work, whereas a high alliance orientation precipitates a positive effect of consulting on firm performance. This paper demonstrates that clients’ task requirements and their alignment towards innovation and alliances have a significant influence on the benefits to the firm conveyed by highly qualified externals. 相似文献

We show in this article that bang-bang portfolio strategies where the investor is alternatively 100% in equity and 100% in cash are dynamically inefficient. Our proof of this result is based on a simple second-order stochastic dominance (SSD) argument. It implies that this is true for any decision criterion that satisfies SSD, not necessarily expected utility. We also examine the stop-loss strategy in which the investor is 100 percent in equity as long as the value of the portfolio exceeds a lower limit where the investor switches to 100 percent in cash. Again, we show that this strategy is inefficient under second-order risk aversion. However, a slight modification of it–in which all wealth exceeding a minimum reserve is invested in equity–is shown to be an efficient dynamic portfolio strategy. This strategy is optimal for investors with a nondifferentiable utility function. 相似文献
