OBJECTIVES To compare the relative effects on performance of sleep deprivation and alcohol. METHODS Performance effects were studied in the same subjects over a period of 28 hours of sleep deprivation and after measured doses of alcohol up to about 0.1% blood alcohol concentration (BAC). There were 39 subjects, 30 employees from the transport industry and(More)
The purpose of this workplace evaluation was to assess the effects on performance, alertness and subsequent sleep of strategic napping on 12-h overnight shifts. In a counterbalanced crossover design, 24 male aircraft maintenance engineers working in a forward rotating 12-h shift pattern volunteered to take part in the study for two work weeks. During the(More)
The effects of 28 h of sleep deprivation were compared with varying doses of alcohol up to 0.1% blood alcohol concentration (BAC) in the same subjects. The study was conducted in the laboratory. Twenty long-haul truck drivers and 19 people not employed as professional drivers acted as subjects. Tests were selected that were likely to be affected by fatigue,(More)
OBJECTIVE To examine risk factors for onset of low back pain (LBP) in healthcare workers. METHODS Nursing students, during their 3 year training period, and 1 year after training were studied in a prospective cohort study, with repeated self reported measurements of determinants of LBP at 6 monthly intervals for 3 years during training, and after a 12(More)
AIMS To determine the number and rates of work-related fatal injuries by employment status, occupation, industry, age and gender in New Zealand 1985-1994. METHODS Potential cases of work-related injury deaths of persons aged 15-84 years were identified from the national electronic mortality data files. Main exclusions were deaths due to suicide and deaths(More)
OBJECTIVE To define health outcomes of whiplash associated disorders (WAD) at three months, six months, and two years after injury and to examine predictors of these outcomes. DESIGN Prospective cohort study. SETTING New South Wales, Australia. SUBJECTS People with compensable motor crash injuries who reported whiplash as one of their injuries. (More)
OBJECTIVES To describe work related fatal injuries to agricultural workers in New Zealand to identify priority areas for further research and injury control measures. METHODS Injury deaths in New Zealanders aged 15-84 inclusive for the period 1985-94 were identified and the coroner's files for these obtained. These files were then reviewed to determine(More)
Six experiments employed an odor-aversion paradigm to investigate the role of the duration of exposure to an odor in determining that odor's subsequent associability with illness. Rats were exposed to an odor at times T1 and T2, and the second of these exposures was followed by toxicosis. When the initial odor exposure was brief, the odor aversion was(More)
Twenty seven professional truck drivers completed a 12 hour, 900 km trip under each of three driving regimes-a relay (staged) trip, a working hours regulated one-way (single) trip, and a one-way (flexible) trip with no working hours constraints. The results indicated that none of the driving regimes prevented fatigue and that the pattern of fatigue(More)
A comprehensive classification system, which allowed operational analysis of the events preceding accidents, was applied to the analysis of information surrounding the occurrence of all traumatic work-related fatalities in Australia in 1982-1984. The coded information included factors immediately antecedent to the accident leading to the fatality and(More)
