An econometric model is used to measure the impact of the Three-Party Programme on European demand for U.S. orange juice. The results show that the programme has helped expand the demand for orange juice in European countries and, from the viewpoint of the U.S. citrus industry, is an economically preferred way of generating additional exports compared with using price reductions to achieve additional sales.  相似文献

Recent research in finance has indicated that the institutional structure in which financial asset prices are determined can have a nontrivial impact on pricing. This report examines transaction level data for Treasury Note futures contracts traded at the Chicago Board of Trade (CBOT) to identify institutional, or market microstructure, impacts on the pricing of these contracts. Relatively few articles have conducted empirical research on the microstructure of U.S. futures trading due to the limited availability of comprehensive transaction level data from the futures exchanges. This report uses the CBOT's Computerized Trade Reconstruction database, a comprehensive transaction level dataset, to identify the price impact of the time duration between trades in a manner analogous to that of A. Dufour and R. F. Engle (2000). Unique differences from prior research include the application to futures contracts with their relative higher frequency of trading, as well as the investigation of the price impact of the number of active traders present on the trading floor and the trading volume. Subsequent price and sign of trade significantly relate to the time duration between trades, the number of floor brokers, and the trading volume. © 2004 Wiley Periodicals, Inc. Jrl.

The purpose of this research was to investigate the effects that user task load level has on the relationship between an individual's trust in and subsequent use of a system's automation. Military decision-makers trust and use information system automation to make many tactical judgments and decisions. In situations of information uncertainty (information warfare environments), decision-makers must remain aware of information reliability issues and temperate their use of system automation if necessary. An individual's task load may have an effect on his use of a system's automation in environments of information uncertainty.It was hypothesized that user task load will have a moderating effect on the positive relationship between system automation trust and use of system automation. Specifically, in situations of information uncertainty (low trust), high task load will have a negative effect on the relationship. To test this hypothesis, an experiment in a simulated command and control micro-world was conducted in which system automation trust and individual task load were manipulated. The findings from the experiment support the positive relationship between automation trust and automation use found in previous research and suggest that task load does have a negative effect on the positive relationship between automation trust and automation use. Experiment participant who incurred a higher task load exhibited an over-reliance on their automated information systems to assist them in their decision-making activities. Such an over-reliance can lead to vulnerabilities of deception and suggests the need for automated deception detection capabilities.  相似文献

The maritime industry provides an interesting case study of the design and implementation of drug-testing programs in the transportation industry during the 1980s. It is clear that such programs were designed and implemented less because of empirical evidence of safety problems than for political reasons. The results in the maritime industry are indicative of a program that is expensive to operate, intrusive with regard to employee privacy, and which will have little or no impact on safety. Focusing such programs on the issue of impairment rather than on the issue of drug usage per se is likely to improve the outcome of the programs. Although, despite common belief, there is little evidence that drug usage or the “drug problem” in U.S. society as a whole had gotten worse in the preceding years (Schonsheck, 1989, 250–251).  相似文献

While the techniques become more sophisticated, the hardware and software go through new generations and we move towards such unexplored options as internet fundraising and legal restraints, the challenges and successes in the field of fundraising and in the personality of fundraisers should not change very much: they are faced with the assignment of making the donors feel important, the causes seem attractive, and making the system move with ease and comfort for everyone concerned. The author gives strong credence to such ‘simple’ matters as appearance, health, ethics, virtue and giving attention to words as well as innuendo. The reader will learn if he or she ‘listens’ to the message of this paper; if, on the other hand, he or she is looking for a shortcut or a foolproof plan short of living and loving in the field, it will not be found — in this or any other paper. Fundraising is a synergestic system: you put everything you know together, and it comes out to equal more than the sum of its parts. Still, you keep on learning. The best fundraiser has not yet been born; the most successful campaign has not yet begun; the wisdom is still being assembled. This paper is one man's overview of where we have been, what we are doing in best practice scenarios, and what is possible if we ‘Look sharp, feel sharp, be sharp and listen’; it includes a good overview of ‘Anecdotal excellence: people, places and things’. The paper starts with a word from God and ends with a reminder for us all: ‘We must remember — to look forward!’ Copyright © 2002 Henry Stewart Publications  相似文献

This article matches establishment-level data on workplace transformation (e.g., quality circles, work teams, and just-in-time production) with measures of cumulative trauma disorders at these same establishments to explore the relationship between "flexible" workplace practices and workplace health and safety. The results reveal a positive, statistically significant, and quantitatively sizable relationship between cumulative trauma disorders and the use of quality circles and just-in-time production.  相似文献

This paper adopts property rights and organization theory perspectives to analyze the process of privatization of state enterprises and performance of newly created shareholding corporations in China. Relying on case study information, the paper concludes that although the shareholding corporations have contributed, to a certain extent, to better performance, their potentials have not been fully realized due to various economic environmental and ideological constraints.  相似文献
