This thesis centers around my autoethnographic performance 900 Gallons; it explores the importance of re-membering oppressive family histories and white supremacist legacies in particular. First, I explore the theoretical frame that whiteness studies offers this project, considering the ways in which performance can disrupt hegemonic whiteness, with specific attention to white invisibility, cultural appropriation and supremacy. Next, I discuss the project’s primary methodologies: performance autoethnography and queer genealogy. Performance autoethnography, I argue, illuminates the discursive potential of privileging both critical distance and critical intimacy. Queer genealogy foregrounds the importance of historiographical descent as well as dissent. Together, these methods reveal the resistant possibilities of embodied scholarship. Finally, I investigate the risks and possibilities of re-performing oppressive histories, arguing that when these narratives are performed with a critical difference, they can create radical possibilities. The Appendix includes the complete 900 Gallons script, as it was performed at the University of Texas on November 3 and 4, 2011. / text

In this essay the author argues against what is defined as radical social constructionism and its place in the relatively new sociology of philosophy in Sweden. A realistic approach is presented as a more plausible and desirable alternative.

A brief review was provided of lipid metabolism, mechanisms of lipid lowering and coronary heart disease risk factors (including the role of antioxidants). In addition, studies of lipid-lowering and other anti-atherosclerotic effects of garlic materials were also reviewed. Evaluation and development of techniques required to perform studies of the anti-atherosclerotic effects of garlic were implemented, including evaluation of methods for measuring total antioxidant capacity and the development of methods for the rapid isolation of low density lipoprotein (LDL). The main objective of this project was to investigate the effects of garlic upon plasma lipids in rats and healthy human subjects and the effects upon antioxidant status in healthy human subjects. In a long-term study with old male rats, a low dose of garlic oil (c. O.5mg/Kg body weight/day) for 12.5 weeks provided in a high fat diet produced no significant reduction in plasma lipids or glucose. Upward trends in plasma lipids early in the treatment period were similar to those reported from several previous studies in which eventual reductions in plasma lipids were observed suggesting the possibility of a small effect of garlic oil upon lipid metabolism. Two randomised, double-blind, placebo-controlled human studies were carried out to investigate the effects of capsules containing garlic oil dissolved in vegetable oil upon coronary heart disease risk factors in normal subjects. In the first study, 8.2 mg/day of garlic oil (or placebo) capsules were given to 51 subjects over an I 1- week period. 95% confidence intervals were calculated for differences between garlic oil and placebo groups of changes in plasma lipids, glucose and total antioxidant capacity between baseline and end-oftreatment. No significant effects were observed, but it was found that plasma lipids and glucose trends were more favourable with garlic oil treatment. Effects of garlic oil over placebo for cholesterol-related variables and glucose were in opposite directions for males and females and this interaction between genders reached significance for high density lipoprotein cholesterol, total cholesterol/high density lipoprotein cholesterol ratio, calculated low density lipoprotein cholesterol and glucose of plasma. The strong gender effect of garlic oil evidenced for plasma lipids and glucose implies potent effects of garlic oil and suggests future garlic studies should include gender analyses. In the second human study, 12 mg/day garlic oil (or placebo) capsules were given to 27 trained young male athletes for 16 weeks. 95% confidence intervals were calculated for differences between garlic oil and placebo groups of changes in plasma lipids, total antioxidant capacity and LDL composition between baseline and end-of-treatment. It was found that the reduction in plasma triglycerides (p=O.09) of the garlic oil group in comparison with the placebo group was accompanied by increases in density, a significant reduction in triglycerides / protein and a trend towards reduction of cholesterol/protein of the LDL fraction. A trend towards reduced total antioxidant capacity / protein of LDL appear to reflect garlic oil effects upon lipid composition of LDL rather than directly upon antioxidants. Non-significant trends towards small improvements in maximal oxygen intake test-duration and less plasma glucose depletion with garlic oil were observed. Overall, the results from the human studies provide some encouragement to the view that garlic oil could reduce coronary heart disease risk in normal persons and that this possibility deserves further investigation.
