Exposure to adverse childhood experiences (ACEs) has lasting repercussions throughout an individual’s lifetime. An adult with a history of childhood trauma is at increased risk for excessive stress reactivity, which exacerbates the development of chronic disease. It is important to investigate how this information can be used for adult trauma survivors. This study assessed the psychophysiological impacts of providing “ACE insight”. Participants completed questionnaires and were given false feedback that their childhood experiences put them at increased risk for excessive stress reactivity and the development of disease. Following ACE insight, participants underwent a speech stressor task during which cardiovascular reactivity was monitored and psychological reactions were assessed. Results indicated that participants with more adverse childhoods reported feeling more worried and less happy about feedback. Further, ACE insight caused a significant increase in cardiac output for participants with a history of childhood trauma. Implications and future directions are discussed.

<p> The hydrogenolysis of propane over 0.5 weight percent ruthenium supported on (see symbol in text)-alumina in a continuous stirred-tank catalytic reactor was studied at various pressures and temperatures. </p> <p> The reaction orders with respect to propane and hydrogen and the activation energies were examined at various pressures. A mechanism was proposed and a Hougen-Watson type of rate expression was obtained from the analysis of the proposed mechanism. </p> <p> The product distributions were studied at various pressures and temperatures. A reaction network involving reversible adsorption-desorption of the hydrocarbons and irreversible rupture of the carbon-carbon bonds in the surface species was applied to the experimental data. </p> <p> The proposed mechanism was consistent with the data for kinetics and selectivity. </p> / Thesis / Master of Engineering (MEngr)
