How The Presence Of A Risk Ladder, Time Interval Comparison, And Smoking Comparison Affect Risk Perception, Steve A. Dinzart
How The Presence Of A Risk Ladder, Time Interval Comparison, And Smoking Comparison Affect Risk Perception, Steve A. Dinzart
Theses and Dissertations
The objective of this study is to increase the knowledge available on the relative effectiveness of risk ladders as a presentation format for explaining risk magnitudes to the public. An experiment was conducted to test the hypotheses that an individual's risk perception varies with the presence of a risk ladder, time interval comparison, and smoking comparison. Subjects were AFIT Professional Continuing Education students, asked to assume a particular level of a health hazard in their homes, to read a brochure explaining the hazard, and then to complete a questionnaire. Results demonstrated that subjects exposed to a graphical risk ladder perceived …

Predicting Mishap Rates At Closing Usaf Maintenance Depots, Douglas E. Mcclain
Theses and Dissertations
It is clear that the Department of Defense and the USAF, in an effort to cut costs, will continue to reduce infrastructure through base closures. This has particular implications to the civilian employee who will likely lose his or her job. The purpose of this study was to review the most recent literature relating to safety and industrial facility closures and develop a theoretical model for predicting accident or mishap rates. From the literature reviewed, a theoretical model is proposed containing five candidate variables intended to measure; perceived adequacy of employee safety training, perceived safety culture, perceived safety climate, self-reported …
C-17/Paratrooper Risk Assessment Analysis, Jose C. Belano
C-17/Paratrooper Risk Assessment Analysis, Jose C. Belano
Theses and Dissertations
The C-17 test and evaluation community has been testing different aircraft formation geometries in search of a configuration which minimizes paratrooper encounter with the wake vortices of upstream aircraft. This thesis develops a simulation tool that the C-17 test and evaluation community can utilize as an advanced risk assessment model to use on proposed formation geometries prior to live testing. The model is developed under the architecture of object-oriented simulation using MODSIM III and parallels similar efforts by the Aerodynamic Decelerator Technology community in creating object-oriented counterparts to already developed trajectory models of various degrees of freedom. This thesis develops …
Analyzing And Improving Stochastic Network Security: A Multicriteria Prescriptive Risk Analysis Model, David L. Lyle
Analyzing And Improving Stochastic Network Security: A Multicriteria Prescriptive Risk Analysis Model, David L. Lyle
Theses and Dissertations
This research optimized two measures of network security by hardening components and improving their reliability. A common measure of effectiveness (MOE) for networks is statistical reliability, which ignores the effects of hostile actions. A new MOE which includes hostile actions was developed. Both measures require component reliability functions, derived using fault trees. Fuzzy Logic and Monte Carlo simulation were used to quantify uncertainty. Results from the model are compared to traditional Risk Assessment results.
