This work describes the evolution and potential of an elective course for students who have already been exposed to the standard techniques of problem solving as presented in traditional courses. Students apply these techniques to large scale problems in directed mullidisciplinary project teams. In doing so, they are provided with a unique learning experience allowing them to serve as a resource to the community. Course projects described here include the promotion of a railing retail district; the formulation, implementation and monitoring of litter reduction strategies; the economic evaluation of using inmate labor to clean public areas; and economic comparisons of recycling strategies for used tires.  相似文献

In this paper, we try to develop a comprehensive theory of risk management for illiquid trading instruments and exotics by examining the consequences of a quasi–static hedging strategy. In contrast to a static hedging strategy, in which an initial hedge once executed is kept in place for the life of the trade, and a dynamic hedging strategy, in which hedges are frequently adjusted over the life of the trade, a quasi–static hedging strategy utilizes hedge adjustments but tries to minimize the frequency. Almost all the examples studied in the framework introduced here take this minimization to the extreme by limiting hedge adjustments to at most one during the life of a trade. We examine the application of this approach to long–dated forwards, long–dated options and exotic options such as cliquet and barriers. The model we present for barriers is a new generation of the Derman–Ergener–Kani approach which combines the flexibility of the approach with a sizable increase in model independence.  相似文献

After highlighting some of the key issues and positions in the debate around appropriate preventive regulation, the paper presents a number of observations directed at the proponents of greater self-regulation. These observations confront directly a number of familiar, but often unchallenged, arguments for self-regulation. More centrally we address claims concerning, the extent to which the chemicals industries have a good and improving ‘safety’ record; and whether the sector consists of companies both motivated and capable in the context of effective crisis and disaster management. Lastly, the paper sets out some ‘new directions’ for the nature and role of regulation in the effective prevention of crises. Thus the paper indicates a number of regulatory developments which are distinct from any shift towards greater self-regulation, but which would result in more effective crisis and disaster prevention in the UK chemicals industries and, indeed, beyond that specific sector.  相似文献

abstract    Studies on the three types of process improvement programmes (Continuous Improvement, Reengineering and Benchmarking) have appeared many times in the literature. These studies suggest that certain organizational variables act as enablers and their presence or absence can significantly influence success rates. Such studies have tended to examine companies where a single programme has been implemented. In contrast, this paper examines a sample of companies who have experienced all three programmes. Our aim is to compare and contrast each programme's impact on firm performance and identify which organizational variables are common and which are programme-specific enablers of success. We build and test an integrative framework to support our analysis. Our study found that: (1) Reengineering delivered the greatest impact on performance; (2) executive commitment was needed to make this happen; (3) strategic alignment was the major influence on the success rate of Reengineering and Continuous Improvement programmes; and (4) employee empowerment was necessary for each programme to work effectively.  相似文献

In several product categories, it is typical to release products sequentially to different markets and customer segments. Conventional knowledge holds that the roles of various product success drivers do not differ significantly across these sequential channels of distribution. The authors examine sequential distribution channels within the motion picture industry and develop a model that proposes that such differences exist between a primary (short- and long-term theatrical box office) and a sequential (video rental) channel. The authors test their model with a sample of 331 motion pictures released in theaters and on video during 1999–2001 using partial least squares. Results reveal differences in the impact of success factors across channels. For example, cultural familiarity enhances box office success but relates negatively to video rental success, and distribution intensity and date of release enhance box office outcomes but have no impact on rental revenues.

This paper studies the introduction of an exchange rate between Ireland and the UK in 1979 to shed light on the effects of a common currency on the composition of international trade. No evidence is found from time series or panel regressions that the change of exchange rate regime had a significant effect on Anglo-Irish trade. This finding is consistent with previous studies of currency unions between larger, developed countries but conflicts with findings based on more heterogeneous country groupings. The reasons for this discrepancy are discussed.  相似文献

The U.S. Departments of Agriculture and Energyjointly analyzed the economic potential for,and impacts of, large-scale bioenergy cropproduction in the United States. Anagricultural sector model (POLYSYS) wasmodified to include three potential bioenergycrops (switchgrass, hybrid poplar, and willow). At farmgate prices of US $2.44/GJ, anestimated 17 million hectares of bioenergycrops, annually yielding 171 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor the land. The estimate assumes highproductivity management practices are permittedon Conservation Reserve Program lands. Traditional crops prices are estimated toincrease 9 to 14 percent above baseline pricesand farm income increases annually by US $6.0billion above baseline.At farmgate prices of US $1.83/GJ, anestimated 7.9 million hectares of bioenergycrops, annually yielding 55 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor the land. The estimate assumes managementpractices intended to achieve highenvironmental benefits on Conservation ReserveProgram lands. Traditional crops prices areestimated to increase 4 to 9 percent abovebaseline prices and farm income increasesannually by US $2.8 billion above baseline.  相似文献
