Beyond Postmodern Margins: Theorizing Postfeminist Consequences Through Popular Female Representation, Victoria Mosher Jan 2008

Beyond Postmodern Margins: Theorizing Postfeminist Consequences Through Popular Female Representation, Victoria Mosher

Electronic Theses and Dissertations

In 1988, Linda Nicholson and Nancy Fraser published an article entitled "Social Criticism Without Philosophy: An Encounter Between Feminism and Postmodernism," arguing that this essay would provide a jumping point for discussion between feminisms and postmodernisms within academia. Within this essay, Nicholson and Fraser largely disavow a number of second wave feminist theories due to their essentialist and foundationalist underpinnings in favor of a set of postmodernist frameworks that might help feminist theorists overcome these epistemological impediments. A "postmodern feminism," Nicholson and Fraser claim, would become "the theoretical counterpart of a broader, richer, more complex, and multilayered solidarity, the sort …

A Numerical Analysis Approach For Estimating The Minimum Traveling Wave Speed For An Autocatalytic Reaction, Erika Blanken Jan 2008

A Numerical Analysis Approach For Estimating The Minimum Traveling Wave Speed For An Autocatalytic Reaction, Erika Blanken

Electronic Theses and Dissertations

This thesis studies the traveling wavefront created by the autocatalytic cubic chemical reaction A + 2B → 3B involving two chemical species A and B, where A is the reactant and B is the auto-catalyst. The diffusion coefficients for A and B are given by DA and DB. These coefficients differ as a result of the chemical species having different size and/or weight. Theoretical results show there exist bounds, v* and v*, depending on DB/DA, where for speeds v ≥ v*, a traveling wave solution exists, while for speeds v < v*, a solution does not exist. Moreover, if DB ≤ DA, and v* and v* are similar to one another and in the order of DB/DA when it is small. On the other hand, when DA ≤ DB there exists a minimum speed vmin, such that there is a traveling wave solution if the speed v > vmin. The determination of vmin is very important in determining …

Field Of View Effects On Reflexive Motor Response In Flight Simulation, Javier Covelli Jan 2008

Field Of View Effects On Reflexive Motor Response In Flight Simulation, Javier Covelli

Electronic Theses and Dissertations

Virtual Reality (VR) and Augmented Reality (AR) Head Mounted Display (HMD) or Head Worn Display (HWD) technology represents low-cost, wide Field of Regard (FOR), deployable systems when compared to traditional simulation facilities. However, given current technological limitations, HWD flight simulator implementations provide a limited effective Field of View (eFOV) far narrower than the normal human 200[degrees] horizontal and 135[degrees] vertical FOV. Developing a HWD with such a wide FOV is expensive but can increase the aviator's visual stimulus, perception, sense of presence and overall training effectiveness. This research and experimentation test this proposition by manipulating the eFOV of experienced pilots …

Trait Arousability And Its Impact On Adaptive Multimedia Training, Sae Schatz Jan 2008

Trait Arousability And Its Impact On Adaptive Multimedia Training, Sae Schatz

Electronic Theses and Dissertations

Today's best intelligent, adaptive, multimedia trainers have shown excellent performance; however, their results still fall far-short of what good human tutors can achieve. The overarching thesis of this paper is that future intelligent, adaptive systems will be improved by taking into account relevant, consistent, and meaningful individual differences. Specifically, responding to individual differences among trainees will (a) form more accurate individual baselines within a training system, and (b) better inform system responses (so that they interpret and respond to observable data more appropriately). One variable to consider is trait arousability, which describes individual differences in sensitivity to stimuli. Individuals' arousability …
