2011 — The Optimal Workplace: Organizational and Managerial Structures Supporting Individual Role Quality in the WorkplaceAbstract
Rationale: The purpose of this thesis is to examine employee perceptions and experiences in order to understand which attributes support the creation and maintenance of an optimal work culture. Aim: The thesis is driven by three areas of inquiry: an individual‘s perception of workplace quality and optimality; organizational and managerial attributes contributing to quality workplaces; and techniques applied in a workplace to achieve an optimal workplace culture and employee experience. Methodology: This investigation is situated under the rubric of the Interpretivist paradigm, which emphasizes the importance of understanding the ‗lived experiences‘ from the point of view of those who live … Read more

2011 — Advanced Music Training and Executive Function: A Neurocognitive StudyAbstract
The objective of this study was to assess the relationship between advanced music training and neurocognitive functioning, with specific focus on executive function, working memory, and tactile interhemispheric transfer. Twenty professional musicians and a comparison group of 19 individuals with no formal music training or performance experience completed a battery of measures of executive functioning, working memory, and interhemispheric transfer. The musician group had an average of 20.4 years (SD = 9.6) of formal music training and had started formal music training at a mean age of 5.8 years (SD = 2.5). Results revealed significantly better performance of the musicians … Read more

2011 — Using Ballistocardiography to Evaluate Cardiac Performance in Trained Male Ice Hockey PlayersAbstract
During exercise the demand on the heart increases considerably. Evidence suggests that long-term exercise training causes adaptations to the heart that are not present in the sedentary, and is commonly referred to as athlete’s heart. It is not unusual for the cardiac adaptations to mimic certain pathological conditions. Therefore, being able to differentiate the athletic heart from the pathological heart has important implications for trained athletes. The presence of cardiovascular disease permits disqualification from competition or cessation of training to prevent progression of the disease or sudden cardiac death. Commonly used diagnostic tools to evaluate cardiac performance (e.g., echocardiography) can … Read more

2011 — Dosimetric Characterization of a Waveguide-Based Exposure System for Laboratory Studies with Unrestrained Mice at 1.9 GHZAbstract
It is essential for research on the biological effects of radiofrequency (RF) electromagnetic energy to be conducted using well-characterized exposure systems in order to ensure the reliability of research outcomes. Realizing this importance, a waveguide-based in vivo exposure system was developed at the Consumer and Clinical Radiation Protection Bureau of Health Canada for conducting laboratory studies with live mice exposed to RF electromagnetic energy. This thesis presents the important aspects and dosimetric characterization evaluation of the developed exposure system. The Health Canada in vivo exposure system consists of four identical cylindrical waveguide chambers, each with a plastic cage for housing … Read more

2011 — Ultrasound Testing System for the Detecting of the Shape and Growth of a Vapor Chamber in the VAPEX ProcessAbstract
Acoustic wave detection systems are designed to estimate distances based on the measurement of the time of arrival (TOA) of an ultrasonic wave. It has been used in diagnoses and treatments in areas such as medicine, dentistry, civil engineering, and many other industrial applications. It has also been applied in the oil industry for pipeline inspection and fluid velocity measurement. In this study, a comprehensive experimental program was designed and conducted to evaluate the feasibility of using acoustic waves for detection and monitoring of vapor chamber growth and pressure front movement in porous media during vapor chamber expansion in the … Read more
