This investigation was conducted in order to show that insanitary conditions may exist in the swimming pool at North Texas State Teachers College provided the proper precautions are not taken; and, in contrast that this pool can be sanitary and entirely safe when operated and used according to the necessary sanitary specifications.

The past few decades have heralded a paradigm shift in the psychology, oncology, and trauma literature. This shift has involved a re-focusing of the empirical lens from the distress and pathology of traumatic experiences to a focus on growth and thriving in response to adversity or traumatic events. Multiple studies have identified that individuals recognise positive changes following their experiences of adversity to the extent that many individuals report development beyond their pre-trauma functioning. These positive changes have been broadly conceptualised as growth, a multidimensional concept, which typically involves an increased appreciation for life, more meaningful relationships, an increased sense of personal strength, a change in priorities, and a richer existential and spiritual awareness. Growth following adversity, or adversarial growth, is still relatively new in sport, and specifically elite sport, and accordingly the purpose of this doctoral research was to explore adversarial growth in elite athletes with a particular emphasis on the experiences of elite level swimmers. The research was grounded in a constructivist paradigm which assumes changing and sometimes conflicting social realities, and seeks to understand people's constructions of their lived experiences.

Aquatic propulsion by means of undulatory movements of the median (dorsal and anal) fins is the primary mode of transport for the Picasso triggerfish (Rhinecanthus aculeatus). Known as balistiform locomotion, this form of propulsion is an adaptation for highly efficient movement within complex environments such as coral reefs. A principle component of balistiform locomotion has been the development of momentum enhancement, a fin-force multiplier that increases swimming efficiency. This study examines the kinematics and energetics of balistiform locomotion employing theoretical models of thrust, power, and efficiency. Thrust and power were calculated and compared with theoretical values modeled by Lighthill and Blake (1990). This model has heretofore not been thoroughly vetted and was tested for accuracy and applicability. Thrust force was estimated from resistance (drag) using a vertical dead drop to determine terminal velocity; power was calculated from oxygen consumption measurements at different speeds. The Lighthill and Blake (1990) model requires median fin kinematics (frequency, wavelength, amplitude, wave angle), which were measured from high-speed videography and followed statistically predicted trends with frequency being the dominant variable, and the others changing little or not at all with speed. Momentum enhancement was found to be 3.6, close to Lighthill and Blake’s (1990) theoretically predicted value of 2.5. Momentum enhancement is experimentally proven here for the first time. Theoretical and empirical thrust force values are closely matched; theoretical thrust is greater at lower speeds and lower at higher speeds. The ratio of theoretical thrust to drag-estimated thrust averages 1.08. Theoretical values for power are greater than those measured by a factor of about 3.6 and cannot be explained by measurement error.

This study examines swimming in fish as a function of the performance of the locomotor musculature. Aspects of evolutionary adaptation and scaling relevant to swimming performance in fish are introduced. The concepts of resistance and capacity adaptations are illustrated in relation to the evolution of the suborder Notothenioidei to the antarctic environment. Alterations in hydrodynamics, swimming performance and efficiency with growth/scaling are discussed.

This report describes the processes, working habits, materials, and multiple iterations of my work over the past three years. I reflect more in depth on my final series of work in which I have incorporated images of empty pool structures into paintings and large drawings. I consider the pool images metaphors for containment, control of the landscape, the unknowable, and in both a material and psychological sense, the void. The objects I exhibit, drawings, paintings and prints, are generated using a convoluted process. Rather than working in a systematic way, I negotiate rapid impulses, subjective goals, and thematic consistency. When I use figure/ground reversal and gestural drawing, I look to create a hand-touched surface that generates a sense of uneasiness in the composition, and a subjective disruption in the landscape. / text
