Asynchronous Level Crossing ADC for Biomedical Recording Applications

Description: This thesis focuses on the recording challenges faced in biomedical systems. More specifically, the challenges in neural signal recording are explored. Instead of the typical synchronous ADC system, a level crossing ADC is detailed as it has gained recent interest for low-power biomedical systems. These systems take advantage of the time-sparse nature of the signals found in this application. A 10-bit design is presented to help capture the lower amplitude action potentials (APs) in neural sign… more

Attachment to God: Pathways to Resilience and Posttraumatic Growth

Description: Having a secure attachment to God may act as a buffer against stress. Secure attachment to God has been positively associated with adaptive outcomes following stress, such as higher levels of stress-related growth and fewer maladaptive symptoms including depression, prolonged grief, and traumatic distress. However, relatively few studies have empirically tested the relationship between attachment to God and resilience and posttraumatic growth. Thus, the current study explored the potential asso… more

"Bad Paper"

Description: Bad Paper follows the lives of former military service members, who have received an other-than-honorable discharge, but also have service-connected post traumatic stress disorder (PTSD). Due to the "suck it up" culture of the military, many of these veterans would not report any psychological troubles in fear of being labeled "weak" and potentially affecting their promotions. With no outlet for their PTSD, drugs and alcohol became a way of "self-medicating," which led to their dismissal from… more

Bio-Inspired Designs to Reduce Human-Exoskeleton Interaction to Prevent Falls in an Aging Population

Description: As a large generation ages, the collective financial and ethical responsibility to prevent egregious bodily harm through fall prevention and gait assistant exoskeleton devices increases. Risk for falls increases with age and the severity of the fall does as well. To support this elderly population, motorized exoskeletons can both increase stability as well as respond faster to fall scenarios, but current models do not more around the existing biological framework. Giving participants a range of… more

Creating a Public Pedagogy for Anti-Rape Activism: How We Learn to Advocate for Others

Description: This thesis explores the way we learn to advocate for sexual assault survivors. This multi-methodological, qualitative study examines both popular cultural representations of sexual assault and official training materials provided by rape crisis centers and domestic violence organizations as sites of pedagogical messaging. I argue that it is imperative to incorporate intersectional feminist frameworks into understanding how advocacy is animated in these different sites of learning. This project… more

Crying for Change: Examining the Use of Period Melodrama and the Melodramatic Mode in Contemporary Queer Representation

Description: This thesis illustrates how Melodrama and the melodramatic mode have been adapted within contemporary cinema as both a means of commenting on prior LGBTQI representation, and of exposing mainstream audiences to the issues still faced by many within this spectrum. Through my analyses of Carol (2015), Brokeback Mountain (2005), and A Single Man (2009), I examine how filmmakers have drawn on Melodrama as both an aesthetic form, and as a reference to the broader field of generic history and critici… more

Development of a Scale to Measure Victim Reliance on a Perpetrator

Description: Betrayal trauma theory (BTT) explains the relationship between a victim and perpetrator to be an especially critical factor for predicting adverse trauma outcomes; however, to date, there is no adequate measure to assess this relationship. We aimed to create a measure of reliance, here defined as dependence on another for food, clothing, finances, emotional support, and more. We utilized a new scale, the Reliance on Perpetrator Scale, to measure this construct. 397 participants completed a batt… more
