Strategic Vulnerability: An Analysis Of Physical Geography, Environmental, And Material Components Of Force Structure, Kyle Christensen
Graduate Theses, Dissertations, and Problem Reports (ETD)
The selection of a military recruitment method has historically been based on material capabilities and military objectives. Recruitment strategies range from coercively conscripting soldiers to encouraging volunteer enlistments. Historically, states around the globe have used large conscripted armies to wage war when they become fully mobilized for protracted military engagements against another state. However, the occurrence of war is by its very nature a rare occurrence in the international system. This begs the question of what types of military recruitment states are using as a function of choice rather than necessity.;Existing literature on the selection of force structure is far …

You Are And You Ain't: Redneck Literature And The Imposition Of Identity, Matthew Joseph Ferrence
You Are And You Ain't: Redneck Literature And The Imposition Of Identity, Matthew Joseph Ferrence
Graduate Theses, Dissertations, and Problem Reports (ETD)
Redneck images pervade contemporary American culture and provide a pattern for national behavior. As globalization and multiculturalism change the demographics of the nation, covert Redneck codes enforce previous hegemonies of race, class, and gender. Imbued with incontestable American character, the Redneck becomes an ideological force capable of defending the nation from destabilizing cultural incursions. The maintenance of these Redneck codes relies on the continued reassertion of Southern and Appalachian stereotypes, since these regions must be maintained as authentic homelands for the identity character.;In this project, I locate a literary genealogy for the American Redneck and examine the roots and function …

The Robust Optimization Of Non-Linear Requirements Models, Gregory Gay
The Robust Optimization Of Non-Linear Requirements Models, Gregory Gay
Graduate Theses, Dissertations, and Problem Reports (ETD)
Solutions to non-linear requirements engineering problems may be "brittle"; i.e. small changes may dramatically alter solution effectiveness. Hence, it is not enough to just generate solutions to requirements problems---we must also assess solution robustness. This thesis aims to address two concerns: (a) Is demonstrating robustness a time consuming task? and (b) Is it necessary that solution quality be traded off against solution robustness?;Using a Bayesian ranking heuristic, the KEYS2 algorithm fixes a small number of important variables, rapidly pushing the search into a stable, optimal plateau. By design, KEYS2 generates decision ordering diagrams (in time experimentally shown to be O(N2)). …
