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

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
