Assessment Of Prolonged Occupational Exposure To Heat Stress, Ximena Garzon-Villalba Garzon-Villalba

USF Tampa Graduate Theses and Dissertations

Heat stress is a recognized occupational hazard present in many work environments. Its effects increase with increasing environmental heat loads. There is good evidence that exertional heat illness is associated with ambient thermal conditions in outdoor environments. Further, there is reason to believe that risk of acute injury may also increase with the ambient environment. For these reasons, the assessment of heat stress, which can be done through the characterization of the wet bulb globe temperature (WBGT), is designed to limit exposures to those that could be sustained for an 8-h day. The ACGIH Threshold Limit Value (TLV) for heat …

Assessing Excessive Noise Exposure Of Music-Oriented Nightclub Employees, Aiyanna Fitzgerald

USF Tampa Graduate Theses and Dissertations

Much research has gone into noise-induced hearing loss (NIHL) and the effects of high intensity noise levels on the hearing mechanism of individuals. A study by the National Institutes of Health has established that high intensity sounds can cause hearing damage of either a temporary, or worse, a permanent nature; regardless of the age of the person. While sound levels below 75 decibels are considered comparatively harmless and have been found not to cause any kind of permanent hearing loss; sound levels greater than 85 decibels and regular exposure of approximately 8 hours per day, on an average, has been …

Critical Heat Stress Evaluation In Two Ebola Ensembles, Christopher T. Lee

USF Tampa Graduate Theses and Dissertations

Ebola, a type of filovirus that causes hemorrhagic fevers, dominated global headlines in 2014 when the largest Ebola epidemic in history took place in West Africa. Healthcare practitioners were at particular risk of contracting Ebola while taking care of patients with the disease because they were easily exposed to bodily fluids such as blood, urine, saliva, and feces, quite often in the intensive care unit (ICU). While personal protective equipment (PPE) protects the healthcare practitioner by providing an effective barrier against the virus, users were also at risk for heat stress because of the type of protective clothing.

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 …

Latino Immigrant Workers’ Search For Justice After Occupational Injury, Carla Gabriela Castillo

USF Tampa Graduate Theses and Dissertations

Latino immigrants encounter an entanglement of rights and policies after occupational injury or illness. In collaboration with an immigrant worker center, ethnographic research and a survey are used to analyze injured workers’ experiences. The center uses survey results to identify common threads and systematic problems, and to explore potential direct action. Through interviews with workers and medical and legal professionals, I investigate the barriers Latino immigrants face following occupational injury or illness, how their lived experiences relate to the greater medicolegal frameworks that demarcate most formal processes of compensation and treatment, and the experiences of professionals who mediate these structures. …

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.

Daily Recovery From Work: The Role Of Guilt, Eunae Cho

USF Tampa Graduate Theses and Dissertations

Acknowledging the critical role that occupational factors play in employee health, researchers have tried to understand ways to reduce the harmful effects of work on employee health. As the process by which individuals recharge resources that have been depleted, recovery has been recognized as important due to its potential to mitigate the negative effects of work on employee well-being. Although the recovery literature has continued to grow, many questions remain unanswered. The purpose of the present study was to expand our knowledge of recovery by examining situational (job characteristics) and individual (trait guilt) predictors of recovery and investigating psychological attributes …

Illegitimate Tasks And Employee Well-Being: A Daily Diary Study, Erin Eatough

USF Tampa Graduate Theses and Dissertations

This dissertation focuses on an occupational stressor that has been recently introduced to the literature, illegitimate tasks, or tasks that seem unreasonable or unnecessary at work. Previous work has demonstrated the relationship between illegitimate tasks and a narrow set of discrete emotions as well as negative employee performance behaviors. The current research contributes to the literature by expanding the nomological network associated with illegitimate tasks and uses a rigorous daily diary methodology in a full-time working sample. It was expected that illegitimate tasks reduce state levels of self-esteem as well as other employee well-being indicators including anger, depressive mood, fatigue, …
