Sound Attenuation Performance Of Fiber-Reinforced Polymer Composite Circumaural Hearing Protection Devices, Steven Christopher Augustine

USF Tampa Graduate Theses and Dissertations

Personnel who work on the flight deck of an aircraft carrier are exposed to extreme levels of jet engine noise often in excess of 140 decibels (dB). The current circumaural hearing protective devices (CAHPD) employed by flight deck crewmen are inadequate for the level of protection required for these extreme levels of noise. Fiber-reinforced thermoset polymer composite (FRPC) materials such as aramid fibers used in body armor, have high theoretical values of acoustic impedance due to a fundamentally high modulus of elasticity and may offer a superior level of hearing protection over original equipment (OE) thermoplastic CAHPDs. The objective of …

Exploring The Energy Link Between Emotion Regulation At Work And Health Behaviors, Ryan Christopher Johnson

USF Tampa Graduate Theses and Dissertations

The present study explores the process through which the regulation of emotions at work, also known as emotional labor, depletes self-regulatory resources, specifically energy, and distally impacts health behaviors in the form of less physical activity and more unhealthy eating. Differences in relationships between two forms of emotional labor, surface acting and deep acting, as well as differences between psychological and physical energy depletion, are explored. Additionally, the roles of trait mindfulness and future temporal focus are examined as between-individual differences moderating the proposed relationships.
