Chief Seattle\u27s speech(es): Ambivalent idealizations and emplacing the uprooted \u27origin\u27

This thesis traces the narcissistic dynamics behind mounting idealizations of a Native American Indian, Chief Seattle, and his renowned speech of 1854. In my work I draw from psychoanalytic, poststructuralist, \u27post-colonial\u27, and translation theories, as well as from contemporary Indian scholarship. I develop my own provisional model of what I term Narcissistic Drift , providing a means of charting the intertextual dynamics driving colonial representations of otherness to converge progressively with stereotypical norms. Where previous Seattle studies have tended to concern themselves with issues of textual \u27authenticity\u27, I build on such work to consider how an indigenous speech \u27uprooted\u27 from its Native American contexts by the written word, has become vulnerable to fetishistic uses by colonial producers, as well as to growing universalist idealization in written and visual media. I resist such trends by re-positioning H.A. Smith\u27s Seattle speech version of 1887, relative to traces of the 1854 oration\u27s political and cultural contexts and codes of interpretation. I find that in Smith\u27s speech version- despite its aestheticizing frame - there is a sense of agency and sophistication in the Salishan elder\u27s rhetorical manouevrings. I argue that Seattle\u27s dynamic position in judgement of the colonizers, located in-between absolute denial and unqualified acceptance of \u27Red\u27/\u27White\u27 brotherhood, becomes erased by subsequent, increasingly assimilationist portrayals. I locate these idealizations of Seattle and his speech at a disempowering site placed across the West\u27s most profound \u27excluded middle\u27- between \u27Nature\u27 and \u27Culture\u27

The Microstructure of Pyrite Blackening in Fossil Shells

The Waynesville formation is part of the stratigraphic succession of Indiana bedrock which allows us to look back on environmental conditions during the late Ordovician period, 450 million years ago. Due in part to a fossil record which is overwhelminlgly dominated by a single species, the Waynesville formation functions as an outdoor labratory illustrating various preservation processes operating on directly comparable shells. Shell blackening during preservation has been a particular point of interest. Based on the correlation of shell blackening with occurrences of shell fragmentation and abrasion in large brachiopods, the shell blackening seen in Upper Ordovician (Cincinnatian) brachiopods has previously been identified as a sign of long residence on the sea floor, and has been attributed to the accumulation of iron sulfides and organics in microborings. This in turn suggests extremely low oxygen microenvironments within shells. The results of our studies are broadly consistent with prior hypotheses.http://opus.ipfw.edu/stu_symp2015/1055/thumbnail.jp

Assessment of two behavioural models (HBM and RANAS) for predicting health behaviours in response to environmental threats: Surface water flooding as a source of groundwater contamination and subsequent waterborne infection in the Republic of Ireland

Extreme weather events (EWEs) are increasing in frequency, posing a greater risk of adverse human health effects. As such, developing sociological and psychological based interventions is paramount to empowering individuals and communities to actively protect their own health. Accordingly, this study compared the efficacy of two established social-cognitive models, namely the Health Beliefs Model (HBM) and Risks-Attitudes-Norms-Abilities-Self-regulation (RANAS) framework, in predicting health behaviours following EWEs. Surface water flooding was used as the exemplar EWE in the current study, due to the increasing incidence of these events in the Republic of Ireland over the past decade. Levels of prior experience with flooding were considered for analyses and comparative tools included a number of variables predicting health behaviours and intervention potential scores (i.e. measure of impact of targeting each model element). Results suggest that the RANAS model provides a robust foundation for designing interventions for any level of experience with an extreme weather event, however, use of the simpler HBM may be more cost-effective among participants unacquainted with an EWE and in relatively infrequent health threat scenarios. Results provide an evidence base for researchers and policymakers to appropriately engage with populations about such threats and successfully promote spatiotemporally appropriate health behaviours in a changing climate

Effect of Annealing Time on Texture Evolution of Fe–3.4 Wt% Si Nonoriented Electrical Steel

Herein, the Effect of Annealing Time on the Texture Evolution in Fe–3.4 Wt.% Si Non-Oriented Electrical Steel is Investigated. Strip Samples Are Cast using a Vacuum Sampling Method, Which Simulate the Solidification Conditions of an Industrial Twin Roll Thin Strip Casting (TRSC) Process. As-Cast Samples with Different Carbon and Sulfur (C&S) Levels Are Hot Rolled (HR) with Varying Levels of Hot Deformation, Cold Rolled (CR) to 0.35 Mm Thickness, and Then Annealed at 1050 °C for Different Holding Times (1, 6, 24 H). to Fe–3.4 Wt.% Si Non oriented Electrical Steel, the Observed Texture Evolution Can Be Divided into Different Stages as Annealing Time is Increased from 1 to 24 H. with Increasing Annealing Time, the Fraction of Goss Texture Decreases Initially and Then Increases Again through the Consumption of Grains with Other Textures. with Additional Time, a Decrease of Pinning Force Due to Precipitate Coarsening Results in Normal Grain Growth, Resulting in an Increase of Grain Size. in This Step, Cube Grains Can Form from Rotated Goss Grains. a Model for Core Loss is Presented and Used to Explain the Core Loss Results

Performance of Masonry Blocks Containing Different Proportions of Incinator Bottom Ash

AbstractThis paper presents the results from an experimental suite of tests as a trial to assess the structural and material performance of masonry blocks with different proportions of incinerator bottom as (IBA) as a fine aggregate replacement. The tests undertaken include compressive and flexural strengths, water absorption and density.Research into the use of waste by-products in construction materials has been increasing over the past 20years. IBA produced in an Irish waste incinerator facility is currently landfilled following pre-treatment. This project assesses the suitability of this IBA to replace 0, 10, 20, 30, 50, 75 or 100% of natural fine aggregates in masonry blocks (100mm high×215mm wide×440mm long) with a design strength of 7N. Structural tests included compressive and tensile strength, density and water absorption in accordance with ASTM C140.The results indicate that bottom ash replacement levels below 20% provide adequate compression and tensile strengths with density and absorption also within satisfactory levels

Screening for peripheral arterial disease and carotid artery disease in patients with abdominal aortic aneurysm

Screening for concomitant atherosclerotic disease is important in cardiovascular risk reduction. This study assessed the prevalence of carotid artery disease (CAD) and peripheral arterial disease (PAD) in patients with known abdominal aortic aneurysms (AAAs). All patients with AAA attending the vascular laboratory between the January 1, 2007, and December 31, 2009, were eligible for a carotid ultrasound and measurement of ankle brachial indices. A total of 389 (305 males) patients were identified on the AAA surveillance program with a mean (±standard deviation) age of 76 (±8) years. The mean age of the males was 75.4 (±7.8) years, and the mean age of the females was 77 (±11) years. A total of 332 patients were assessed for CAD, and 101 (30.4%) of those were found to have significant disease. A total of 289 patients were assessed for PAD of which 131 (45.3%) were found to have PAD at rest, and 289 patients were assessed for both and 59 (20.4%) patients had significant CAD + PAD. Patients with AAAs are at high risk of other atherosclerotic disorders, and, therefore, they should receive intensive medical optimization

Fatty Acids Increase Neuronal Hypertrophy of Pten Knockdown Neurons

Phosphatase and tensin homolog (Pten) catalyzes the reverse reaction of PI3K by dephosphorylating PIP3 to PIP2. This negatively regulates downstream Akt/mTOR/S6 signaling resulting in decreased cellular growth and proliferation. Co-injection of a lentivirus knocking Pten down with a control lentivirus allows us to compare the effects of Pten knockdown between individual neurons within the same animal. We find that knockdown of Pten results in neuronal hypertrophy by 21 days post-injection. This neuronal hypertrophy is correlated with increased p-S6 and p-mTOR in individual neurons. We used this system to test whether an environmental factor that has been implicated in cellular hypertrophy could influence the severity of the Pten knockdown-induced hypertrophy. Implantation of mini-osmotic pumps delivering fatty acids results in increased neuronal hypertrophy and p-S6/p-mTOR staining. These hypertrophic effects were reversed in response to rapamycin treatment. However, we did not observe a similar increase in hypertrophy in response to dietary manipulations of fatty acids. Thus, we conclude that by driving growth signaling with fatty acids and knocking down a critical regulator of growth, Pten, we are able to observe an additive morphological phenotype of increased soma size mediated by the mTOR pathway
