Performing Perfection: Plastic and Cosmetic Surgery and the Rhetorical BodyHarris-Moore, Deborah Rose (The University of Arizona., 2011)While there is a long history of rhetorical studies that focus on oral and written discourses, the relatively recent trend of studying rhetorical images, materiality, and rhetorical bodies presents a shift toward an expanded perspective on what constitutes texts and what can be considered rhetorical. The study of bodies as rhetorical texts prompts the questions of how language is material and visual in nature. In my dissertation I examine the relationship between rhetoric and the body through Judith Butler's theories of materiality and performativity. Using Butler's theories of performance as a lens, I analyze the rhetoric of plastic and cosmetic surgery and demonstrate the role of performance in the perpetuation of and response to rhetoric of the body. Cosmetic and plastic surgery are performatives in that they not only confer a binding power on the action performed by altering the body through surgical and non-surgical means, but also initiate various citational practices within the field of medicine and in popular culture (through various mediums such as television, magazines, billboards, and websites). These procedures result in images and claims that authorize particular social expectations of beauty, youth, and sexuality.I examine a range of mass media texts related to cosmetic surgery (television shows, magazines, news clips, websites, and films) that portray different normative and deviant performativity of the body. In my research, I include interviews from volunteers in Los Angeles; my analysis involves local individuals' relationships to plastic and cosmetic surgery and their various body performatives in terms of normativity and agency. By comparing global and local perspectives, I argue that media sensationalizes the agent/victim binary in order to sell plastic and cosmetic surgeries, as well as related texts. The local stories serve to counter assumptions about the role of power in plastic surgery, revealing a far more complicated relationship between clients, rhetoric, and the reasons behind their surgeries; the agent/victim binary that is emphasized in mass media fails to capture lived experience and creates a detrimental rhetoric of empowerment.
Augmented Reality for Spatial Perception in the Computer Assisted Surgical TrainerWagner, Adam (The University of Arizona., 2017)Traditional laparoscopic surgery continues to require significant training on the part of the surgeon before entering the operating room. Augmented Reality (AR) has been investigated for use in visual guidance in training and during surgery, but little work is available investigating the effectiveness of AR techniques in providing the user better awareness of depth and space. In this work we propose several 2D AR overlays for visual guidance in training for laparoscopic surgery, with the goal of aiding the user's perception of depth and space in that limiting environment. A pilot study of 30 subjects (22 male and 8 female) was performed with results showing the effect of the various overlays on subject performance of a path following task in the Computer Assisted Surgical Trainer (CAST-III) system developed in the Model Based Design Lab. Deviation, economy of movement, and completion time are considered as metrics. Providing a reference indicator for the nearest point on the optimal path is found to result in significant reduction (p < 0.05) in subject deviation from the path. The data also indicates a reduction in subject deviation along the depth axis and total path length with overlays designed to provide depth information. Avenues for further investigation are presented.
