Subjective Fatigue In A-6, F-14, And F/A-18 Aircrews During Operations Desert Shield And Storm, C. A. Dejohn, S. A. Shappell, D. F. Neri Oct 1992

Subjective Fatigue In A-6, F-14, And F/A-18 Aircrews During Operations Desert Shield And Storm, C. A. Dejohn, S. A. Shappell, D. F. Neri

Fatigue occurring during naval air combat can reduce performance, impair operational effectiveness, and compromise safety. This study examines the effect of combat missions on the subjective fatigue of naval aircrews deployed aboard USS AMERICA during Desert Shield and Desert Storm. Fatigue was determined using three questionnaires that were completed before and after each mission. Although fatigue significantly increased during combat missions, it usually returned to preflight levels by the next day without noticeably increasing as the operation progressed. We feel that judicious aircrew scheduling on the part of operational planners was one of the most important factors contributing to this …

This study of urban, multi-ethnic children was undertaken to explore the relationships between age, cognitive developmental capability (termed ‘cognitive maturity’) and accuracy of information about health problems. A total of 299 children in the first, second and third grades from six public and one private school hi New York City were individually interviewed using an open-ended set of questions. Findings indicated that having accurate health information is not the same as comprehending the abstract internal nature of the ‘facts’. Results supported Piaget's levels of cognitive development applied to the area of health. Findings also showed that age is a better …


The Effect Of Combat On The Work/Rest Schedules And Fatigue Of A-6 And F-14 Aviators During Operation Desert Shield/Storm, David F. Neri, Scott A. Shappell Aug 1992

The Effect Of Combat On The Work/Rest Schedules And Fatigue Of A-6 And F-14 Aviators During Operation Desert Shield/Storm, David F. Neri, Scott A. Shappell

Publications

During Operation Desert Shield/Storm, A-6 and F-14 aviators aboard USS AMERICA completed daily activity logs and provided subjective measures of fatigue. Aviators flew frequently at night during Desert Storm, but without substantial sleep-related fatigue or problems. A likely contributing factor was the large number of naval aviation assets brought into the combat theater, allowing workload to be shared and activity and rest times to be properly managed. However, raster plots of the data suggest that there may have been an additional contributing factor. The AMERICA travelled eastward from the east coast through seven time zones and became involved in combat …


Effects Of Dextro-Methamphetamine On Subjective Fatigue, C. A. Dejohn, Scott Shappell, D. F. Neri Aug 1992

Effects Of Dextro-Methamphetamine On Subjective Fatigue, C. A. Dejohn, Scott Shappell, D. F. Neri

Declining aircrew performance during periods of sustained flight operations (SUSOPs) has underscored the need to develop effective countermeasures. This paper reports on the ability of the central nervous system (CNS) stimulant d-methamphetamine to alleviate the detrimental effects of a simulated SUSOPs on subjective fatigue. Subjective fatigue was repeatedly measured by three questionnaires. The simulated SUSOP started at 1800 and consisted of a 9-h planning session followed by 4 h of rest and a 14-h mission. After 6 h of sleep, the 9/4/14 work/rest/work pattern was repeated. At 4 1/2 h into the second mission, 13 subjects were administered 10 mg …


The Effect Of Combat On Aircrew Subjective Readiness And Lso Grades During Operation Desert Shield/Storm, Scott A. Shappell, David F. Neri May 1992

The Effect Of Combat On Aircrew Subjective Readiness And Lso Grades During Operation Desert Shield/Storm, Scott A. Shappell, David F. Neri

The effect of operational tasking on aircrew readiness during combat operations continues to be an area of intense investigation within the U.S. Navy. The recent Persian Gulf War provided a unique opportunity to collect data examining aircrew work/rest cycles and operational tasking in a combat environment. For 4 consecutive weeks during Operations Desert Shield and Desert Storm, 18 A-6 and 18 F-14 aviators onboard the USS AMERICA (CV-66) completed daily work/rest logs of their activities while conducting operations from the Red Sea. Activities on the work/rest logs were coded to a resolution of one-half hour. Several flight parameters were also …


An Introduction To The Five-Factor Model And Its Applications, Robert R. Mccrae, Oliver P. John Jan 1992

An Introduction To The Five-Factor Model And Its Applications, Robert R. Mccrae, Oliver P. John

Public Health Resources

The five-factor model of personality is a hierarchical organization of personality traits in terms of five basic dimensions: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience. Research using both natural language adjectives and theoretically based personality questionnaires supports the comprehensiveness of the model and its applicability across observers and cultures. This article summarizes the history of the model and its supporting evidence; discusses conceptions of the nature of the factors; and outlines an agenda for theorizing about the origins and operation of the factors. We argue that the model should prove useful both for individual assessment and for the elucidation …
