Description
This study analyzes syllabi for first-year college composition courses and interview responses to examine how the choices made by instructors affect online course design. Using the Syllabus Assessment Instrument designed by Madson, Melchert and Whipp (2004), this dissertation looks specifically at attendance and participation policies, course behavior policies, contact information, required material choices, course organization decisions and tool decisions to reveal how instructors do or do not accommodate online class pedagogies. This study finds that the choices instructors make in syllabus design provide significant information about the overall online course design itself. Using Selber's multiliteracies as a frame for understanding the choices made by instructors, this study finds that instructors focus primarily on functional literacies in their discourses and in the way they communicate their choices to students. Instructors vary in how they inform students of the mechanics of how to interact with tools, how often to interact with the online course, and how to use the tools within the online course. While these aspects of online courses are important, focusing on these aspects of the online course overshadows alternative perspectives on tool use that could encourage critical reflection by both instructors and students. To help instructors and departments design more effective syllabi and courses, this study raises questions and offers observations about how instructors communicate policies and how they understand these policies and pedagogies in online courses. In providing general guidelines for syllabus design and course design, this study will help writing instructors and composition programs better understand the significance of the choices they make in online course design.

Description
Both law and medicine are interpretive practices, and both systems have historically worked in tandem, however ineffectively or tumultuously. The law is, by social mandate, imagined as a "fixed" system of social control, made up of rules and procedures grounded in a reality that is independent of language; although we know that law is both revised and interpreted every day in courtroom practice, to imagine the law, the system that keeps bad people behind bars and good people safe, as indeterminate or, worse, fallible, produces social anxieties that upend our cultural assumptions about fairness that predate our judicial system. This imaginary stability, then, is ultimately what prevents the legal system from evolving in consonance with developments in the mental health professions, as inadequate as that discursive system may be for describing and categorizing the infinite possibilities of mental illness, specifically where it is relevant to the commission of a crime. Ultimately, the insanity plea raises the specter of the endless interpretability of the law and mental illness and, therefore, the frailty of the justice system, which makes each insanity defense trial emblematic of larger social anxieties about social control, fairness, and susceptibility to mental illness or the actions of mentally ill people.

Description
This dissertation theorizes nineteenth-century public performance of spiritual media as being inherent to the production of autobiography itself. Too often, dominant social discourses are cast as being singular cultural phenomena, but analyzing the rhetorical strategies of women attempting to access public spheres reveals fractures in what would otherwise appear to be a monolithic patriarchal discourse. These women's resistant performances reap the benefits of a fractured discourse to reveal a multiplicity of alternative discourses that can be accessed and leveraged to gain social power. By examining the phenomena of four nineteenth- century Spiritualists' mediumship from a rhetorical perspective, this study considers how female spirit mediums used their autobiographies to operate as discursive spaces mediating between private and public spheres; how female mediums constructed themselves in the public sphere as women and as spiritual authorities; how they negotiated entry into volatile and unpredictable publics; how they conceived of the vulnerability of the female body in the public sphere; and how they coped with complications inherent to Victorian era constructions of feminine corporeality. In conclusion, this dissertation offers a highly situated performative theory of subaltern publicity.

Description
At its core, this dissertation is a study of how one group of ordinary people attempted to make change in their local and national community by reframing a public debate. Since 1993, over five thousand undocumented migrants have died, mostly of dehydration, while attempting to cross the US/Mexico border. Volunteers for No More Deaths (NMD), a humanitarian group in Tucson, hike the remote desert trails of the southern Arizona desert and provide food, water, and first aid to undocumented migrants in medical distress. They believe that their actions reduce suffering and deaths in the desert. On December 4, 2008, Walt Staton, a NMD volunteer placed multiple one-gallon jugs of water on a known migrant trail, and a Fish and Wildlife officer on the Buenos Aires National Wildlife Refuge near Arivaca, Arizona cited him for littering. Staton refused to pay the fine, believing that he was providing life-saving humanitarian aid, and was taken to court as a result. His trial from June 1-3, 2009 is the main focus of this dissertation. The dissertation begins by tracing the history of the rhetorical marker "illegal" and its role in the deaths of thousands of "illegal" immigrants. Then, it outlines the history of NMD, from its roots in the Sanctuary Movement to its current operation as a counterpublic discursively subverting the state. Next, it examines Staton's trial as a postmodern rhetorical situation, where subjects negotiate their rhetorical agency with the state. Finally, it measures the rhetorical effect of NMD's actions by tracing humanitarian and human rights ideographs in online discussion boards before and after Staton's sentencing. The study finds that despite situational restrictions, as the postmodern critique suggests, subjects are still able to identify and engage with rhetorical opportunities, and in doing so can still subvert the state.

Description
This research examines four stateswomen fashion icons—Jacqueline Kennedy Onassis, Diana, Princess of Wales, Michelle Obama, and Catherine, the Duchess of Cambridge—and the way these stateswomen used clothing and personal style to create a public identity. Dress is a powerful tool of personal expression and identity creation and when we look at stateswoman style, we see the ways that dress gives them agency to negotiate the “official” identity that’s being placed on them. Personal style is the way we use personal adornments (clothing, jewelry, cosmetics, etc.) to form messages about who we are, who we dream we could be, and what our personal values are. It is a system of communication with rhetorical influence on others that, in return, offers a way to embrace, challenge, or subvert societal expectations and cultural norms. The choice to embrace, challenge, or subvert to the expectations is fluid, and the women continuously move back and forth between these states. I argue for the ways the selected women in this analysis make choices and negotiate such expectations on the national stage through their clothing choices.
While personal style does not construct our identities on its own, our dress is often the first indicator of our identity and personality. Dress, therefore, becomes one way to express our identity, even in situations where we are otherwise silenced. Stateswomen are “not body as advertisement”—as celebrities are—but “body as a source of agency.” For every woman, stateswomen included, clothing is a rhetorical statement that they make every day. These women exemplify the way choices can be made powerfully—because they are “like us” more than fashion icons. These stateswomen icons show the public evolving negotiations between personal and public style and identity. They demonstrate the ways that clothing choices can be empowering ways to construct identity and use clothing as an identity statement. This is instrumental in helping average women of the public learn how they can use clothing as a rhetorical statement that creates agency and identity.

Breast microcalcifications are a potential indicator of cancerous tumors. Current visualization methods are either uncomfortable or impractical. Impedance measurement studies have been performed, but not in a clinical setting due to a low sensitivity and specificity. We are hoping to overcome this challenge with the development of a highly accurate impedance probe on a biopsy needle. With this technique, microcalcifications and the surrounding tissue could be differentiated in an efficient and comfortable manner than current techniques for biopsy procedures. We have developed and tested a functioning prototype for a biopsy needle using bioimpedance sensors to detect microcalcifications in the human body. In the final prototype a waveform generator sends a sin wave at a relatively low frequency(<1KHz) into the pre-amplifier, which both stabilizes and amplifies the signal. A modified howland bridge is then used to achieve a steady AC current through the electrodes. The voltage difference across the electrodes is then used to calculate the impedance being experienced between the electrodes. In our testing, the microcalcifications we are looking for have a noticeably higher impedance than the surrounding breast tissue, this spike in impedance is used to signal the presence of the calcifications, which are then sampled for examination by radiology.

Description
Breastfeeding has been shown by a number of studies to have numerous benefits on both the mother and the infant. Major health organizations such as the World Health Organization (WHO), now agree that breastfeeding should be encouraged and supported in all countries. But like many things, the wheels of the law are slow to catch up with scientific evident. Although breastfeeding is supported, working women do not have the option of breastfeeding without consequences. For example, in 2003, Kirstie Marshall, a then member of parliament in Australia was ejected from the lower house chamber on February 23, for breastfeeding her baby [3]. According to standing order 30 at the time, "Unless by order of the House, no Member of this House shall presume to bring any stranger into any part of the House appropriated to the Members of this House while the House, or a Committee of the whole House, is sitting" [3]. The rules did not specify the age of strangers, so the then 11-day-old baby, Charlotte Louise and her mother were shown the exit door of parliament. She had to choose between being present at times of major discussions or leaving the house to breastfeed her child, she chose to leave. More recent statistics show that developed nations like the US and Australia which also have high rates of women employment had low rates of breastfeeding. This might mean that workplace policies do not favor breastfeeding or expressing milk at work. Fortunately, laws have since been introduced in both the United States and Australia that support breastfeeding at the workplace. The next step would be to access how these laws affect breastfeeding statistics and how variation between these two countries like the paid parental leave in Australia (which is not present in all US states) would affect these numbers.

Description
Ketone bodies are produced in the liver from the acetyl CoA derived from fatty acids that cannot enter the Krebs cycle. This is a sub-analysis of a larger study which had numerous outcome markers. This analysis focuses on the relationship between ketone blood levels and cognition. The study looked at the relationship between Time Restricted Feeding (TRF), a method of intermittent fasting. TRF is something that can be easily adapted into an individual’s lifestyle and has been shown to have multiple advantages. This 8-week study began with 23 enrolled participants, but due to COVID-19 only 11 participants could be tested for cognition and blood ketone levels after week 4. All participants had similar ranges of weight, height, age, BMI, hip, and waist measurements at baseline. Moreover, these demographic variables were not related to ketone levels or cognition. The data indicate that ketone bodies increased in participants practicing TRF and that the increase in ketone bodies in the blood, specifically β-hydroxybutyrate was strongly correlated to increased cognitive function. This is consistent with theories that elevated ketone levels allowed for early hunter-gather communities and other mammals to survive prolonged periods of nutrient deprivation while keeping high cognitive function.

The purpose of this thesis experiment was to design and create an Acoustically Active Cannula (AAC), which is furnished by a piezoelectric crystal placed at its tip that produces an acoustic navigation signal. I tested the functionality of the cannula in vitro and demonstrated its navigational abilities in vivo in anesthetized pigs. This experiment was based upon ultrasound science and technology, and thus some practical experience with conventional (B-mode) and Doppler ultrasound was achieved as well. The results of bench and experimental animal studies indicated proper functionality of the AAC for identification and spatial navigation of its tip with color Doppler ultrasound imaging.

The academic study of eSports, or professional competition through the medium of video games, has tended to focus on players' motivations to play and watch eSports as well as marketing concerns of huge eSports corporations. Instead of utilizing marketing or psychology to analyze this phenomenon, I investigate three areas of focus in accordance with available literature: the fans and their characteristics, the design of the game itself, and the relationship between fans and the game's developer. This investigation was conducted by first examining existing literature surrounding eSports fans, then collecting public domain data such as Reddit posts, forum posts, and YouTube videos, and last by studying interviews with developers and players. With this thesis, I apply a fan studies approach to eSports by creating a series of indicators based in each of the three focus areas which can be utilized as a systematic method of evaluating an eSport's popularity and growth.
