Southern Sapphisms: Sexuality And Sociality In Literary Productions, 1974-1997, Jaime Cantrell Jan 2014

Southern Sapphisms: Sexuality And Sociality In Literary Productions, 1974-1997, Jaime Cantrell

LSU Doctoral Dissertations

Southern Sapphisms: Sexuality and Sociality in Literary Productions, 1974-1997, considers how queer and feminist theories illuminate and complicate the intersections between canonical and obscure, queer and normative, and regional and national narratives in southern literary representations produced during a crucial but understudied period in the historical politicization of sexuality. The advent of New Southern Studies—and its nascent emphasis on sexuality as an organizing principle of social relations—has focused almost exclusively on midcentury texts from the Southern Renascence, largely neglecting post-1970 queer literatures. At the same time, despite these developments in southern studies, most scholarship in women’s and feminist studies continue …

Accountable Actors: Politics And Poetic Imagination In Huxley, Lewis, And Orwell, Sarah Beth Vosburg Jan 2014

Accountable Actors: Politics And Poetic Imagination In Huxley, Lewis, And Orwell, Sarah Beth Vosburg

LSU Doctoral Dissertations

What does it mean, and what does it take, to practice personal responsibility in the face of political oppression? In this dissertation, I trace the essential themes of responsibility through a critical analysis of three stories: Aldous Huxley’s Brave New World, C. S. Lewis’s That Hideous Strength, and George Orwell’s Nineteen Eighty-Four. No comparative study of these important works of twentieth-century political literature exists. Yet, each of these stories merits the attention of students of character and politics because all three unforgettably portray men who strive to live meaningful lives against the contrived meaning imposed on them by those in …

Expression Of O-Linked N-Acetylglucosamine Modified Proteins And Production And Characterization Of Chlamydia Trachomatis Ct663, Octavia Y. Goodwin

LSU Doctoral Dissertations

O-linked â-N-acetylglucosamine is a regulatory post translational modification. This modification occurs on nearly all functional classes of proteins, in the nucleus and cytoplasm. O-GlcNAc is added to serine or threonine by O-GlcNAc transferase and removed by O-GlcNAcase. Previous attempts to study O-GlcNAc-modified proteins have resulted in low yields, making 3-dimensional structure determination impossible. In this dissertation O-GlcNAc transferase will be co-expressed with domains of human cAMP responsive element-binding protein (CREB1) and Abelson tyrosine-kinase 2 (ABL2) in E. coli, to produce O-GlcNAc-modified protein. The O-GlcNAc-modified protein was expressed in a variety of E. coli cell lines at a variety of conditions, …

Conducting Polymer Nanowires For Multi-Analyte Chemiresistive Sensing, Edward Song Jan 2014

Conducting Polymer Nanowires For Multi-Analyte Chemiresistive Sensing, Edward Song

LSU Doctoral Dissertations

A conducting polymer nanowire-based chemiresistive sensor array was developed for the liquid-phase multi-analyte detection. The ability to distinguish and quantify multiple chemical species with a single sensory device can be useful in many areas including food industry, pollution control, biosensors, and explosives detection. A polyaniline nanowire is a good candidate for use as a chemiresistive sensing material due to its large resistivity change and ease of synthesis. However the two most important issues in chemiresistive sensors are the reproducibility in sensing and the selectivity in chemical species. For improving the reproducibility in polyaniline-based chemiresistive sensing, a self-calibration mechanism was proposed. …

Battered Men And Our Changing Attitudes Toward Intimate Partner Violence, Ashley Marie Perry Jan 2014

Battered Men And Our Changing Attitudes Toward Intimate Partner Violence, Ashley Marie Perry

LSU Doctoral Dissertations

The Center for Disease Control (CDC) (2009) estimates that 4.8 million women are victims of intimate partner assault and rape every year. Receiving far less attention in the intimate partner violence literature, however, are studies of the 2.9 million male victims of this type of abuse (CDC 2009). Here I seek to explore this evolving issue of intimate partner violence, and determine to what extent the situations of male victims imitate the abundant body of literature on male violence against women. Using Google’s NGram word corpus (Michel et al. 2010), I examine important changes over time in the usage of …

Combinatorial Minimal Free Resolutions Of Ideals With Monomial And Binomial Generators, Trevor Mcguire Jan 2014

Combinatorial Minimal Free Resolutions Of Ideals With Monomial And Binomial Generators, Trevor Mcguire

LSU Doctoral Dissertations

In recent years, the combinatorial properties of monomials ideals and binomial ideals have been widely studied. In particular, combinatorial interpretations of minimal free resolutions have been given in both cases. In this present work, we will generalize existing techniques to obtain two new results. If Lambda is an integer lattice in the n-dimensional integers satisfying some mild conditions, S is the polynomial ring with n variables and R is the group algebra of S[Lambda], then the first result is resolutions of Lambda-invariant submodules of the Laurent polynomial ring in n variables as R-modules. A consequence will be the ability to …
