It is commonly believed that breast cancer dragon boating benefits survivors in a range of psychosocial areas, but there have been few empirical studies to investigate such relationships. An interpretive description design and a critical health promotion approach were used to explore the psychosocial experiences of women who breast cancer dragon boat. In-depth interviews with six participants were analyzed. Themes that arose from the data are: (1) moving past isolation — networks of like-minded support, (2) taking control,(3) journey into adventure, (4) affirmative outlook, (5) confronting painful experience, (6) rebuilding identity, (7) and spiritual engagement. The findings illustrate that dragon boating provides breast cancer survivors with a significant venue for change and the opportunity to move beyond traumatic elements of cancer. / Arts, Faculty of / Social Work, School of / Graduate

Marine safety education initiatives are most often constructed along rational functionalist lines that tend to assume that accidents and deaths that accompany them are caused by lack of appropriate technical knowledge, equipment failure or the irrational behaviour of participants. One sector identified by this research, which seems to have a disproportionally high rate of involvement in these incidents, is that of small open skiffs < 5.5m - usually made from aluminum. Most of these incidents take place on the inland waterways of the Canadian Shield. I look at the activity from the perspective of two separate but parallel discourses on the topic: the official discourse as portrayed by the Canadian Coast Guard, Search and Rescue, the Power and Sail Squadrons, the Canadian Red Cross and various police forces and the popular discourse as seen in lifestyle commercials, advertising catalogues, outdoors sporting goods shows and sports television. I suggest throughout that gender, race and economic marginality are powerful influences that must be factored into our educative efforts if we, the Canadian boating public, are to reduce the number of fatalities. The construction of the subjectivites of the participants will be considered in the context of several competing conceptions concerning the nature of Nature in the postmodern era. A form of narrative analysis known as deconstruction is used to interrogate the theoretical foundations of the textual artefacts. I use postcolonial theory to develop a distinctively Canadian narrative concerning the underpinnings of a reconceptualized marine safety education. In the final section, some considerations for extending this work into other areas of wilderness recreation were explored.

This thesis investigates the detection and classification of small boats using a passive sonar system. Noise radiated from a small boats consists of broadband noise and harmonically related tones that correspond to parameters in the boats engine and propeller. A novel signal processing method for detection and discrimination of noise radiated from small boats has been developed. There are two main components to the algorithm. The first component detects the presence of small boats by the harmonic tonals radiated from the boat propeller and engine. The second component was designed to extract the a signature from passive sonar data. The Harmonic Extraction and Analysis Tool (HEAT) was designed to estimate the fundamental frequency of the harmonic tones, track the fundamental frequency using a Kalman filter, and automatically extract the amplitudes of the harmonic tonals to generate a harmonic signature for the boat. The algorithm is shown to accurately extract theses signatures, and results show that the signatures are unique enough that the same boat passing by the hydrophone multiple times can be recognized.
