This paper examines the process of interaction between consumers and providers of dental services in terms of the key selection and evaluation criteria employed by consumers. Focusing on the United Kingdom, it examines the impact of changes in both pricing and provision on the utilisation and evaluation of dental services. Based on a questionnaire survey of dental patients, in the context of the evolving body of literature concerned with consumer behaviour in respect of services, the paper attempts to improve the current understanding of the key factors shaping consumer choice in respect of professional services. Specifically, it argues that the highly complex nature of professional services impacts on patterns of consumer behaviour, resulting in the relationship between the individual service professional and the consumer being the focus of consumer evaluation. This in turn has significant implications for the effective marketing of such professional services. 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

This paper addresses the supply-side explanations of a logger shortage by estimating an occupational choice model that considers the role of earnings, nonpecuniary determinants and intergenerational factors. Our results showed that: (1) relative earnings have no statistically significant effect on career choice; (2) improvement in the public image of loggers substantially increases entry into logging; and (3) a strong intergenerational supply linkage exists but is currently being eroded. 相似文献

Reform of agricultural policies, notably the continuing elimination of production‐enhancing subsidies, makes it possible for policies to respond to social issues such as the rural environment and health in future. In this paper, we draw on a Rural Economy and Land Use (RELU) research project which is examining the potential for the development of healthy food chains and the implications for human health and the environment. One of the key issues to be addressed is consumers’ willingness to pay for the nutritionally enhanced food products from these new chains, but it is evident that only a partial understanding can be gained from a traditional economics approach. In the paper, we discuss how economists are beginning to incorporate views from other disciplines into their models of consumer choice. 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
