Using Improvement Science To Address Early Elementary Teacher Efficacy And Competency When Addressing Trauma-Induced Behavior, Laura Hayes
Masters Theses & Specialist Projects
As more research sheds light on the effects of trauma on school-age children, educators must learn to apply the research and make adaptations in the classroom and school settings. While the body of literature has grown, limitations still exist in research focused on specific strategies and applications for classroom teachers. Many teachers feel ill-equipped and exhibit low self-efficacy when working with students affected by trauma. As a result, many students receive disciplinary action rather than constructive practices that promote healing. Some teachers feel that more targeted and specific training and resources would improve efficacy, confidence, and effectiveness. In this study, …

Social jetlag (SJL), or the shifting of behavior and sleep times between weekdays and weekends, is a pervasive form of circadian rhythm disruption that affects nearly 70% of the population to some extent. The magnitude of SJL can be determined by the difference in the mid-sleep phase between weekends and weekdays. Higher levels of SJL have been associated with lower levels of cardiorespiratory fitness, and increased incidence of cardiometabolic disease, which may be due, in part, to mitochondrial dysfunction. However, no studies to date have evaluated the effects of long term SJL on cardiac mitochondrial dynamics. PURPOSE: To determine …

The acute effects of heat therapy on glycemic markers oppose those of the chronic effects. While the postprandial glucose response is exaggerated during whole body heat exposure, chronic heat exposure lowers HbA1c. Additionally, the acute effects of heat therapy differ depending on the amount of body exposed to heat. Heating a single hand does not increase fasting glucose and lowers postprandial glucose. The opposing effects of partial and whole body heat exposure could be mediated in part from increased sympathetic nervous system (SNS) activity following heat stress. While heating the body increases muscular blood flow and glucose uptake, SNS activation …
