Effects of Alcohol Expectancies, Drinking Behaviors, and Ecological Contexts on Negative Alcohol-Related Consequences among University FreshmenBrule, David 01 May 2017 (has links)
The purpose of this study is to assess a hypothesized model of the influences of alcohol-related expectations, drinking behaviors, and ecological contexts, on first-year college students’ experience of negative, alcohol-related consequences. Growing concern about college student alcohol abuse and its critical consequences has elicited extensive research, prevention, and intervention efforts by academic institutions. Understanding the impacts and interactions of the cognitive, behavioral, and contextual influences associated with college student alcohol abuse is crucial to developing prevention and intervention efforts that effectively mitigate these issues. This investigation analyzed data gathered through the University of Oregon’s AlcoholEdu program to assess the influences and interactions of alcohol expectancies, specific drinking behaviors, and ecological contexts on the development of negative alcohol-related consequences among 3,240 first year university students. The model proposed in this study assessed the influences and interactions of students’ (a) positive and negative alcohol expectancies, (b) engagement in high-risk drinking, (c) use of protective behavioral strategies, and (d) exposure to ecological risk and protective contexts, on their experience of negative alcohol-related consequences. Implications for further research, intervention and prevention efforts are discussed.

2014 / Thermal Barrier Coatings (TBC’s) created by Electron Beam Physical Vapour Deposition (EB-PVD) are
widely used in the aerospace industry. Advancements in the field however are hindered by the cost and time required for research and development. Hence, there exists a need for a more comprehensive understanding of coating parameter interactions to better predict response values without the need for extensive pre-production testing.
This thesis seeks to provide a response surface for EB-PVD coatings, by investigating the following EB- PVD independent input variables: electron beam emission current, gas ratio, vacuum pressure, substrate temperature, roughness and process time in order to generate a predictive statistical model. Output variables were numerous, however emphasis was placed on: TBC coating thickness and density of columns generated during the process. It is impossible to select an “optimum process recipe”; rather, there exists many optimal combinations suited to specific coating structure and its application. Therein lies the need for this model, able to predict TBC properties according to input variables.
Using ALD’s Smart Coater (ALD Vacuum Technologies GmbH), a ceramic top coat (Yttria partially stabilized zirconia, YPSZ, ZrO2-7%Y2O3) was deposited onto 40x30x5mm Inconel 617 samples with NiAl bond coat. These samples were subsequently tested to determine coating properties. The research will show that the complex nature of EB-PVD TBCs may be simplified, at least to a certain
degree through a statistical analysis of the interactions between process variables.
