Psychophysically Derived Work Frequencies Associated With Roof Shingling Operations Involving Change In Grade, Sang Dae Choi
Dissertations
The objective of this study was to investigate the effect of roof slope on psychophysical roof shingling frequency. Twelve healthy males (21-30 years old) were used as participants. Experiment one was designed to determine Maximum Acceptable Roof Shingling Frequency (MARSF) for a workday period using psychophysical methodology. Results indicate that 198 shingles/hr is an acceptable roof shingling frequency for a workday. Furthermore, 2 hours is an acceptable testing period (equivalent to the workday). Postural sway and physiological variables support these findings. Experiment two was designed to study the effect of slope (18°, 26°, and 34°) on MARSF. Experiment two indicates …
The Effect Of An Unconscious Auditory Stimulus On Pilot Performance Under Varying Instrument Flying Conditions, Christina Eleni Christakou
The Effect Of An Unconscious Auditory Stimulus On Pilot Performance Under Varying Instrument Flying Conditions, Christina Eleni Christakou
Master's Theses - Daytona Beach
Human error remains a significant contributing factor with respect to accidents in civil air transportation. It is therefore crucial to establish avenues by which performance on the flightdeck can be enhanced under conditions of distress. The purpose of this study was to examine whether an unconscious auditory stimulus (UAS) could enhance pilot performance under varying instrument flight (IFR) conditions on the aircraft flightdeck. Forty IFR student pilots underwent two eight-minute simulated flights, whereupon they were presented with different IFR weather conditions. During the trial, the experimental group listened to a UAS, whereas the control group listened to white noise (WN). …
Gender Differences In Preference For Learning Environment Among Aviation Education Students, Eric M. Moyer
Gender Differences In Preference For Learning Environment Among Aviation Education Students, Eric M. Moyer
Master's Theses - Daytona Beach
This study investigated whether differences existed between sex, male and female, for the preference of three different syllabi describing three different learning environments. Learning environments consisted of collaborative, and individual, with the individual sub-divided into competitive, and individual while co-varying participants for credit hours. 264 surveys were administered to students in freshman, sophomore, junior, and senior classes in order to collect preference, and demographic data. The surveys were presented as three fictional syllabi differing only in class grading format, and a paragraph on the instructional philosophy of the professor. Instructional philosophies described the proposed environment of the class by enforcing …
