Description
A series of pyrite thin films were synthesized using a novel sequential evaporation
technique to study the effects of substrate temperature on deposition rate and micro-structure of
the deposited material. Pyrite was deposited in a monolayer-by-monolayer fashion using
sequential evaporation of Fe under high vacuum, followed by sulfidation at high S pressures
(typically > 1 mTorr to 1 Torr). Thin films were synthesized using two different growth processes; a
one-step process in which a constant growth temperature is maintained throughout growth, and a
three-step process in which an initial low temperature seed layer is deposited, followed by a high
temperature layer, and then finished with a low temperature capping layer. Analysis methods to
analyze the properties of the films included Glancing Angle X-Ray Diffraction (GAXRD),
Rutherford Back-scattering Spectroscopy (RBS), Transmission Electron Microscopy (TEM),
Secondary Ion Mass Spectroscopy (SIMS), 2-point IV measurements, and Hall effect
measurements. Our results show that crystallinity of the pyrite thin film improves and grain size
increases with increasing substrate temperature. The sticking coefficient of Fe was found to
increase with increasing growth temperature, indicating that the Fe incorporation into the growing
film is a thermally activated process.

Description
This dissertation considers the potential of desire to protect humans, animals, and the environment in the biopolitical times of late capitalism. Through readings of recent South African Literature in English from a postcolonial ecocritical perspective, this project theorizes desire as a mode of resistance to the neocolonial and capitalist instrumentalization of communities of humans and nonhumans, where they are often seen as mere "resources" awaiting consumption and transformation into profit. Deleuze and Guattari posit this overconsumption as stemming in part from capitalism's deployment of the psychoanalytic definition of desire as lack, where all desires are defined according to the same tragedy and brought into a money economy. By defining desire, capitalism seeks to limit the productive unconscious and attempts to create manageable subjects who perform the work of the capitalist machine--subjects that facilitate the extraction of surplus value and pleasure for themselves and the dominant classes. Thinking desire differently as positive and as potentially revolutionary, after Deleuze and Guattari, offers possible resistances to this biopolitical management. This different, positive desire can also change views of others and the world as existing solely for human consumption: views which so often risk bodies towards death and render communities unsustainable. The representations of human and animal desires (and often their cross-species desires) in this literature imagine relationships to the world otherwise, outside of a colonial legacy, where ethical response obtains instead of the consumption of others and the environment by the dominant subjects of capitalism. This project also considers other attempts to protect communities such as animal rights, arguing that rethinking desire is a necessary corollary in the effort to protect communities and lives that are made available for a "non-criminal putting to death" since positive desire precedes the passing of any such laws and must exist for their proper administration. These texts often demonstrate the law's failures to protect communities through portraying corrupt officials who risk the communities they are charged with protecting when their protection competes with government officials' personal capitalist ambitions. Desire offers opportunities for imagining other creative options towards protecting communities, outside of legal discourse.

Description
The hagiographic comedy written by Tirso de Molina Los lagos de San Vicente (1607) presents the journey of Santa Casilda in search of the cure of an illness in her blood that affects her. Casilda rejects the medical assistance offered to her by Muslim doctors and miraculously she finds the cure in the Christian world. In this quest, the intellectual and theological evolution of the future saint in defense of the Christian faith is presented. This dissertation will study the resources that Tirso de Molina employs to show the rejection and displacement against the Islamic world represented by a series of erotic behaviors that, in the effort of dramatizing these impertinences they are characterized within a second discourse. Tirso de Molina takes advantage of the hagiographic comedy's discourse nature and the baroque's obscure literary characteristics to express his messages. This dissertation will study in detail how the combination of hagiographic theatrical elements with linguistic expressions are used to convey a subversive discourse that therefore suggests the application of queer theory as a frame of reference. As a result of this investigation it is concluded that Tirso de Molina promotes the hagiographic model and in order to contrast the triumph of the moral Catholic world over the immoral Muslim world the play writer makes references to the nefarious sin.

ABSTRACT As a writer and a journalist, I have always been interested in narrative. When I moved to the small town of Wickenburg, Arizona in 2003, and began to get acquainted, a friend said to me, "The only way you leave Wickenburg is in a box." The town of Wickenburg places much importance on its history, a focus that led me to explore its related literature of the U.S. West, moving from there to think about evocative objects, collections, and to Material Culture Theory. This thesis considers three objects as springboards for exploring identity, sense of place, memory, and the narrative threads that bring these together. Two of these objects are specific to local history. The first is one of the leather badges worn by the women of Las Damas, a Wickenburg horse riding association. The second is a bronze sculpture, "Fatal Dismount," created by local rancher Mary Cooper Hamill, in which the artist depicts a moment, highly significant to her family, that also speaks to and from local history. The third object is a gold bead heirloom necklace that was handed down to me, the fifth-generation recipient. I conclude with a discussion of how evocative objects, handed down across generations, shape two memoirs by Isabel Allende, Paula, and My Invented Country. In the case of each object, the study of material culture provides a framework for understanding how women have created spaces for themselves, both now and in the past by interacting with objects, articulating identities, making meaning and re-creating history through memories and storytelling.

Description
Reduced space is an important theme in the works of the Marquis de Sade including his epic novel The New Justine and his pornographic performance piece Philosophy in the Bedroom including the political/social treatise "Frenchmen, yet another effort is needed if you want to be a Republic". Through out his life Sade attempted to overcome reduction of space with writing. Tragically, his writing often prolonged the reduction of his space by sending him to or keeping him in prison. It is my theory that his violent, pornographic writing style is "une écriture de surjouissance" or "a writing of over-coming". Surjouissance is my theory for Sade's method, based on textual analysis of Sade's main works, that he combines through his syntactic structure, narrative voice, and semantic themes the orgasm of the mind represented by philosophical discourse with the orgasm of the body represented textually by orgiastic scenes and the language of orgasm to reach an ultimate state of complete freedom. In the political pamphlet "Frenchmen yet another effort..."Sade attempts to set this theory of sur-jouissance, or this transcendent state reached through the combination of physical and philosophical orgasm, as the political foundation for a new republic. Does he succeed in creating a viable political formula for a sustainable republic? My argument states absolutely not. His aristocratic elitism narrows his voice. But he does propose the combination of sexual, literary, and intellectual freedoms as a possible polemic against any form of reduced space.

Description
The increased use of commercial complementary metal-oxide-semiconductor (CMOS) technologies in harsh radiation environments has resulted in a new approach to radiation effects mitigation. This approach utilizes simulation to support the design of integrated circuits (ICs) to meet targeted tolerance specifications. Modeling the deleterious impact of ionizing radiation on ICs fabricated in advanced CMOS technologies requires understanding and analyzing the basic mechanisms that result in buildup of radiation-induced defects in specific sensitive regions. Extensive experimental studies have demonstrated that the sensitive regions are shallow trench isolation (STI) oxides. Nevertheless, very little work has been done to model the physical mechanisms that result in the buildup of radiation-induced defects and the radiation response of devices fabricated in these technologies. A comprehensive study of the physical mechanisms contributing to the buildup of radiation-induced oxide trapped charges and the generation of interface traps in advanced CMOS devices is presented in this dissertation. The basic mechanisms contributing to the buildup of radiation-induced defects are explored using a physical model that utilizes kinetic equations that captures total ionizing dose (TID) and dose rate effects in silicon dioxide (SiO2). These mechanisms are formulated into analytical models that calculate oxide trapped charge density (Not) and interface trap density (Nit) in sensitive regions of deep-submicron devices. Experiments performed on field-oxide-field-effect-transistors (FOXFETs) and metal-oxide-semiconductor (MOS) capacitors permit investigating TID effects and provide a comparison for the radiation response of advanced CMOS devices. When used in conjunction with closed-form expressions for surface potential, the analytical models enable an accurate description of radiation-induced degradation of transistor electrical characteristics. In this dissertation, the incorporation of TID effects in advanced CMOS devices into surface potential based compact models is also presented. The incorporation of TID effects into surface potential based compact models is accomplished through modifications of the corresponding surface potential equations (SPE), allowing the inclusion of radiation-induced defects (i.e., Not and Nit) into the calculations of surface potential. Verification of the compact modeling approach is achieved via comparison with experimental data obtained from FOXFETs fabricated in a 90 nm low-standby power commercial bulk CMOS technology and numerical simulations of fully-depleted (FD) silicon-on-insulator (SOI) n-channel transistors.

Description
The most horrific, darkest, and powerful forms of the sublime take place inside the enclosure of the human psyche; the interior of the mind is the playground for the sublime--not the crag and canyon filled natural world. For Immanuel Kant and Edmund Burke, the driving force of the power of the sublime stems from the feelings of pain and fear: where is that more manifested than in the mind? Unlike the common, traditional, and overwhelmed discussion of Percy Shelley and his contemporaries and the power of the sublime in nature, I will argue that in The Cenci, Shelley, through well-chosen diction and precise composition of terrifying images, fashions characters and scenes in an emotion-driven play that elevates the mind of the reader to a transcendent sublime experience. Through a discussion of the theories of the aesthetic of the sublime laid out by Longinus, Burke, and Kant, I will provide a foundation for the later discussion of the rhetorical sublime evoked by Shelley in the ardent and horrifying play that is The Cenci. Looking at the conventional application of the theories of the sublime to romantic writing will make evident the holes in the discussion of the sublime and romantic writings that have almost forgotten the powerful and psychological rhetorical aspect of the sublime that is emphasized in the theoretical writings of both Burke and Kant. To clarify what is traditionally associated with Shelley and the sublime, a brief analysis of the Shelleyean sublime and Shelley's 1816 poem "Mont Blanc" will prepare the reader for an unconventional, but every bit important and powerful, function of the sublime in the 1819 play The Cenci based on the horrific happenings of a historical 16th century Italian noble family.

Description
The critical-thinking skill of problem solving needs to be part of the curriculum for all students, including those with learning disabilities living in poverty; yet, too often this is not the case. Too often students in poverty and students with learning disabilities are provided a curriculum that is watered down, focused on the basics, and aimed at managing their behaviors instead of helping them learn to think critically about their world. Despite their challenges, these students can learn to problem solve. Educators need to help students make connections between the critical-thinking skills learned in school and the problem-solving skills needed for life. One solution might be to use literature with characters facing similar problems, hold grand conversations, and teach them a problem solving method. Together, these three parts have the potential to motivate and lead students to better thinking. This action research study explored whether literature with characters facing similar problems to the study's participants, grand conversations, and the I SOLVE problem solving method would help students with disabilities living in poverty in the Southwestern United States develop the problem-solving skills they need to understand and successfully navigate their world. Data were collected using a mixed methods approach. The Motivation to Read Profile, I SOLVE problem-solving survey, thought bubbles, student journals, transcripts from grand conversations, and researcher's journal were tools used. To understand fully how and to what extent literature and grand conversations helped students gain the critical thinking skill of problem solving, data were mixed in a convergence model. Results show the I SOLVE problem-solving method was an effective way to teach problem-solving steps. Scores on the problem-solving survey rose pre- to post-test. Grand conversations focused on literature with character's facing problems led to an increase in students' motivation to read, and this population of students were able to make aesthetic connections and interpretations to the texts read. From these findings implications for teachers are provided.

Description
Michel Tremblay, one of the most renowned and beloved Quebecois writers, began his literary career in the 1960s. He is well known for writing many of his works exclusively in the Quebec dialect of joual. The history of Quebec, from its beginnings as a permanent settlement of New France, to its subsequent takeover by the British after the signing of the Treaty of Paris in 1763, all were events that set the stage for the Quiet Revolution. The Quiet Revolution was a cultural, social and linguistic uprising set in motion by the French-speakers of Quebec who were tired of being dominated. Up until the 1960s, the majority of literary works produced in Quebec followed the classical French tradition. The desire in the 1960s to break free from the domination of the English language and culture as well as to be differentiated from the French from France brought with it a newfound nationalistic pride. From this point forward there was a push to create a distinct Quebecois literature. One way to differentiate the works of Quebec from those from France was to include characters and settings from within the Quebec society as well as to have those characters speak in their native dialect. Joual, a dialect version of the pronunciation of the French word cheval, meaning horse, was originally a rural dialect that eventually found its way to the inner city. For this reason, joual was most closely identified with the urban working-class of Montreal. This dialect was also perceived as the language of an uneducated, socially and economically inferior segment of the French-speaking Quebec society. By using joual in his literature, Tremblay was able to depict the social, cultural and economic effect that joual had on this element of Quebec's population. This thesis focuses on the impact of joual on this society through the study of two of Tremblay's plays: Les Belles-soeurs (1965), to show a women's perspective about a socially and economically inferior group, and Hosanna (1973), to show the perspective of homosexuals and transvestites, a socially prejudiced group.

Description
ABSTRACT This collection of poetry focuses on the experiences of a soldier who served six years in the Army National Guard and eleven months in Iraq. The collection is primarily divided into six sections (though each is not separated explicitly) and each section generally involves activities such as training for Iraq, deploying to Iraq, and returning home. In these poems, the speaker recalls different scenes from his experiences: encountering roadside bombs; performing guard duty; burning feces in a can; and living on small military base while at war. The main goal is to provide the reader with an in-depth, sincere, and unfiltered look at the life of a soldier in the military, and of course, in Iraq. The work relies on mostly free verse form with some of the work utilizing the sonnet form and couplets. The poems were greatly influenced by the work of Modernist Poets including Ezra Pound, William Carlos Williams, and T.S. Eliot. This entire collection, which often does fall into that long trail of the war-poem genre, was influenced greatly by the following notable poets who went to war or served in the military: Isaac Rosenberg, Wilfred Owen, Yusef Komunyakaa, Randall Jarrell, and Bruce Weigl.
