Imperial Illness: Considering the Trope of Madness in Michelle Cliff\u27s No Telephone to Heaven

The purpose of this thesis is to examine Michelle Cliff’s No Telephone to Heaven (1996), and to scrutinize, through Christopher’s mental illness, the couched, unspoken, and deeply embedded presence of imperial hegemony in the Caribbean. I shall argue that Christopher’s mental illness is not, as one might have it, an inexplicable lapse into insanity, but both a fitting, polyrhythmic expression of longstanding postcolonial/neocolonial abuse, and a dynamic form of counterhegemonic resistance. Thus, my use of the term, imperial illness, refers to colonial impacts on the Caribbean, and how those impacts continue to play a significant role in postcolonial/neocolonial societies and, concurrently, the strategies imagined by postcolonial subjects to resist. Christopher’s mental illness, then, is the result of sustained imperial socio-psychological torment, which produces, quite ironically, the conditions that make possible his acts of resistance

Core Multiplication in Childhood

A dedicated, non-symbolic, system yielding imprecise representations of large quantities (approximate number system, or ANS) has been shown to support arithmetic calculations of addition and subtraction. In the present study, 5–7-year-old children without formal schooling in multiplication and division were given a task requiring a scalar transformation of large approximate numerosities, presented as arrays of objects. In different conditions, the required calculation was doubling, quadrupling, or increasing by a fractional factor (2.5). In all conditions, participants were able to represent the outcome of the transformation at above-chance levels, even on the earliest training trials. Their performance could not be explained by processes of repeated addition, and it showed the critical ratio signature of the ANS. These findings provide evidence for an untrained, intuitive process of calculating multiplicative numerical relationships, providing a further foundation for formal arithmetic instruction.Psycholog

The Postmodern Indian: Representation and the Films of Sherman Alexie

For hundreds of years, Native Americans have been characters in American media. For most of those years, whites determined the way in which Native Americans were represented. First in print, radio, silent movies and later talkies and television, representations of Native Americans have included being uneducated sidekicks, savages, noble savages seeking to steal white women, drunken idiots, or hilarious jesters all for the entertainment of viewers. This troublesome history of negative depictions of Native Americans is the reason this research is directed at the films by Native American writer and filmmaker Sherman Alexie. This research is a qualitative analysis of two of Alexie\u27s films striving to analyze his work as a Native American filmmaker in relation to themes and representations found in films made by non-Natives depicting Native American characters and cultur

The Impact of Symbolic and Non-Symbolic Quantity on Spatial Learning

An implicit mapping of number to space via a “mental number line” occurs automatically in adulthood. Here, we systematically explore the influence of differing representations of quantity (no quantity, non-symbolic magnitudes, and symbolic numbers) and directional flow of stimuli (random flow, left-to-right, or right-to-left) on learning and attention via a match-to-sample working memory task. When recalling a cognitively demanding string of spatial locations, subjects performed best when information was presented right-to-left. When non-symbolic or symbolic numerical arrays were embedded in these spatial locations, and mental number line congruency prompted, this effect was attenuated and in some cases reversed. In particular, low-performing female participants who viewed increasing non-symbolic number arrays paired with the spatial locations exhibited better recall for left-to-right directional flow information relative to right-to-left, and better processing for the left side of space relative to the right side of space. The presence of symbolic number during spatial learning enhanced recall to a greater degree than non-symbolic number—especially for female participants, and especially when cognitive load is high—and this difference was independent of directional flow of information. We conclude that quantity representations have the potential to scaffold spatial memory, but this potential is subtle, and mediated by the nature of the quantity and the gender and performance level of the learner

Design and Analysis of a Low Temperature Co-Fired Ceramic Micro Combustor

This thesis details the design and construction of a Low Temperature Co-Fired Ceramic (LTCC) micro combustion system. The design of the combustor requires a detailed analysis of the flame’s operational properties and stability. To this end, an analytic model was created to address these concerns. These results were used in conjunction with a detailed numerical analysis to determine the stable operating range of the combustors. The combustion of gaseous fuels requires a device with a lower bound on the channel feature size. This lower limit for combustion corresponds to the minimum quenching distance of the specific fuel being used and usually corresponds to the upper end of silicon MEMs processing techniques and the lower end of meso-scale production processes. This millimeter size range represents the normal feature size range for the LTCC tape system. A potential material imposed restriction to using LTCC is the relatively low temperature operating range when compared to the adiabatic flame temperatures encountered in the combustion of gaseous fuels. To address this concern an analytic model of the heat transfer from a simple straight channel device is presented. This model allows for the analysis of the thermal loads in the substrate as well as provides insight into the effects of the channel geometry on the stability of the flame. Several experimental devices were designed and tested in accordance with the predictions of the analytic model. These devices have similar geometric configurations with different characteristic lengths to explore the feasible operating regimes of the LTCC micro combustor. This allows for the validation of the flame stability margins and heat transfer properties predicted by the analytic model. Infrared imaging allows for the mapping of the device surface temperature and provides a correlation mechanism to the analytic model. The results of the experimental testing show the same trending characteristics predicted by the analytic analysis. However, a detailed numerical analysis is needed to fully capture the quantitive power production capabilities of the device

Intensity enhancement of O VI ultraviolet emission lines in solar spectra due to opacity

Opacity is a property of many plasmas, and it is normally expected that if an emission line in a plasma becomes optically thick, its intensity ratio to that of another transition that remains optically thin should decrease. However, radiative transfer calculations undertaken both by ourselves and others predict that under certain conditions the intensity ratio of an optically thick to thin line can show an increase over the optically thin value, indicating an enhancement in the former. These conditions include the geometry of the emitting plasma and its orientation to the observer. A similar effect can take place between lines of differing optical depth. Previous observational studies have focused on stellar point sources, and here we investigate the spatially-resolved solar atmosphere using measurements of the I(1032 A)/I(1038 A) intensity ratio of O VI in several regions obtained with the Solar Ultraviolet Measurements of Emitted Radiation (SUMER) instrument on board the Solar and Heliospheric Observatory (SoHO) satellite. We find several I(1032 A)/I(1038 A) ratios observed on the disk to be significantly larger than the optically thin value of 2.0, providing the first detection (to our knowledge) of intensity enhancement in the ratio arising from opacity effects in the solar atmosphere. Agreement between observation and theory is excellent, and confirms that the O VI emission originates from a slab-like geometry in the solar atmosphere, rather than from cylindrical structures.Comment: 17 pages, 4 figures, ApJ Letters, in pres

Outcomes Comparison of Enculturating Advance Directives Process at a Health System

The Center for Medicare and Medicaid Services requires organizations to comply with the Patient Self-Determination Act by having processes that inform patients about their rights to execute an advance directive (AD) and engage in shared decision-making. The aim of this study was to compare AD data from a previous study (1999–2002) to a postenculturation (2011–2015) of a structured process for documented patient’s preferences. Second, to conduct a descriptive, bivariate analysis of the enculturated structured ADs process during 2011 and 2015. This descriptive, comparative analysis included 500 random patients from four hospitals, and the enculturated descriptive analysis included 302 patients from six hospitals. Comparisons showed less no ADs and a greater institutional ADs post compared with pre (p \u3c .05). Fifty-four percent of patients from 2011 to 2015 had an AD, and none of them had resuscitative measures when Do-Not-Resuscitate status was ordered. This enculturated process which includes education for health-care professionals and the community facilitates optimal patient, family-centered care
