Examining the Links between Narcissism Domains and Self-Concept Clarity, Self-Esteem, Attachment, Emotion Regulation, and Aggression

Description: Narcissism is currently being redefined as a multidimensional construct. While some researchers hold that narcissism remains a unidimensional phenomenon, others have suggested that bi- and tridimensional conceptualizations may better represent the construct as well as align more succinctly with the experiences of individuals with varying levels of narcissistic traits. Also, since the latter conceptualizations offer a broader assessment of narcissistic tendencies, they may provide greater accura… more

Annihilators of Irreducible Representations of the Lie Superalgebra of Contact Vector Fields on the Superline

Description: The superline has one even and one odd coordinate. We consider the Lie superalgebra of contact vector fields on the superline. Its tensor density modules are a one-parameter family of deformations of the natural action on the ring of polynomials on the superline. They are parameterized by a complex number, and they are irreducible when this parameter is not zero. In this dissertation, we describe the annihilating ideals of these representations in the universal enveloping algebra of this Lie su… more

Hochschild Cohomology of Finite Cyclic Groups Acting on Polynomial Rings

Description: The Hochschild cohomology of an associative algebra records information about the deformations of that algebra, and hence the first step toward understanding its deformations is an examination of the Hochschild cohomology. In this dissertation, we use techniques from homological algebra, invariant theory, and combinatorics to analyze the Hochschild cohomology of skew group algebras arising from finite cyclic groups acting on polynomial rings over fields of arbitrary characteristic. These algebr… more

Rapid, Approximate Multi-Axis Vibration Testing

Description: Sequential single-axis vibration testing strategies often produce over-testing when qualifying system hardware. Multi-axis excitation techniques can simulate realistic service environments, but the hardware and testing strategies needed to do so tend to be costly and complex. Test engineers instead must execute sequential tests on single-axis shaker tables to excite each degree of freedom, which the previous two decades of vibration testing literature have shown to cause extensive over-testing … more

Deep Learning Methods to Investigate Online Hate Speech and Counterhate Replies to Mitigate Hateful Content

Description: Hateful content and offensive language are commonplace on social media platforms. Many surveys prove that high percentages of social media users experience online harassment. Previous efforts have been made to detect and remove online hate content automatically. However, removing users' content restricts free speech. A complementary strategy to address hateful content that does not interfere with free speech is to counter the hate with new content to divert the discourse away from the hate. In … more

Study of Information Behavior of Opportunistic Insiders with Malicious Intent

Description: Enterprises have focused on mechanisms to track insiders who may intentionally exceed and misuse their authorized access. However, there is an opportunity to understand why a trusted individual would want to exploit the trust and seek information with the intent of a malicious outcome. The detection of insider rogue or nefarious activities with information to which a user is already authorized is extremely difficult. Such insider threats require more deliberation than just considering it to be … more

"Her Terrible Splendor"

Description: Her Terrible Splendor is a poetry collection that transports the Greek witch-goddess Circe from her mythical island of Aeaea to modern-day East Texas, where I was raised. By locating Circe in the Piney Woods, I heighten the strangeness that I identify with that setting and open up new contexts for considering Circe as a woman, as an enchanter, and as figure of retelling and revision. Circe appears in an array of roles—friend, lover, mentor, alter-ego, muse—as the poems view her through differen… more
