This thesis explores self determination through the lens of Cree First Nation members located in northeastern Alberta, Canada. The researcher utilizes the talking circle to explore how Cree leaders define self determination. Four prominent themes; 1) identity and western influences 2) personal transformation 3) searching for nehiyaw pimatsowin and 4) commitment and responsibility evolve from the stories shared. Cree spirituality and the need to involve ‘self’ in ceremony proves to be the foundation upon which Cree self determination is founded. This thesis moves towards, “Learning Self Determination Through the Sacred Embedded Teachings and Responsibilities given to Cree Women by the Creator”. / Graduate

Leadership research has traditionally focused on the organizational context and is largely dominated by micro-leadership theories that describe specific styles of leadership. The current research advances previous work by introducing two general interpersonal frameworks – attachment theory and self-determination theory – in order to better understand how leaders relate to those around them in the workplace context. In addition, the current series of studies considers leadership not only in the traditional organizational context, but also in the context of other workplace settings wherein there may not be traditional leadership roles. The central research question was that leaders with more secure attachment orientations would provide greater need support to their employees. In other words, when leaders held positive views of themselves and others, they would be inclined to provide employees with choices, a sense of volition, feelings of connectedness, and efficacy about their abilities. This association was expected to be observed in a variety of leadership contexts. In Study 1, using hospitality managers (N = 104), results indicated that fearful and avoidant attachment (insecure attachment) predicted lower levels of reported need support provision in hypothetical scenarios. Results also indicated that the traditional leadership styles that most research includes did not explain any additional variance in need support beyond that accounted for by attachment orientation. In Study 2, using a sample of students (N = 106) and an experimental design, both secure Attachment and Leadership attachment and positive affect led to higher levels of reported need support provision in hypothetical scenarios. Finally, in Study 3 (N = 154), using a sample of life and business coaches, coaches’ preoccupied attachment orientation predicted lower levels of reported need support in hypothetical scenarios. In addition, coaches’ preoccupied attachment predicted lower levels of reported empathy provision, whereas coaches’ secure attachment predicted higher levels of reported empathy provision. This is the first known research to bring together attachment theory and self-determination theory in a series of three studies with different samples (hotel managers, students and coaches), and multiple research designs (experimental and non-experimental), all focusing on the leadership context. The findings and associated implications are discussed in the context of previous research and future research directions. / Graduate

The presence of ultra-trace levels of mercury in industrial gas and condensate streams is a cause of both environmental and production concern. The toxic nature of the element, in all forms, together with its ability to shut-down large processing plants dictates a need for its accurate and precise measurement. The study which investigated the recovery of various mercury species, spiked into synthetic and real condensate samples using conventional and new digestion and/or extraction techniques showed recovery was dependent upon the speciation. Using the most efficient technique, L-cysteine with persulphate, recoveries of over 90 % were obtained for diphenyl mercury, ethyl and phenyl mercury chlorides and mercury chloride. The recovery of 15% for the important dimethyl mercury species limits the use of this technique. A novel technique has been developed for the determination of total mercury in complex liquid hydrocarbons. Samples (up to 1.0 ml) were vaporised (400°C) and swept through a gold-coated silica trap maintained at 200°C, which retained all mercury species and discarded the matrix. The trap when heated to 900°C released the mercury for measurement by atomic fluorescence spectrometry (AFS). The recoveries for eight mercury species spiked (10 to 50 ng ml -1) into toluene and condensate were generally over 90 %. The instrumental limit of detection (LOD) was 11 pg. The total mercury content of gas condensates, gasolines and heavy oils were determined. Gas chromatography coupled, via a pyrolysis interface, with AF detection was able to determine mercury species in gas condensate, at picogram levels (LOD: 2.5 to 7 pg) using a direct sample injection procedure. For a given column system the positive identification and quantification of up to eight mercury species was obtained. A maximum injector temperature of 125 °C was recommended, to avoid the conversion of species. Mass balance calculations show a strong correlation between the total mercury content and the sum of the lower diallcyl mercury species, for all condensate samples studied. Three commercially available mercury removal systems, A, B and C produced a reduction in the mercury content of hydrocarbon streams under pilot plant conditions. The two stage system, 'A', produced a minimum of 30 % conversion from organomercury to elemental mercury after the hydrogenation reaction in stage 1. While elemental mercury was adsorbed by the stage 2 reactor, the organomercury species were not removed. The single stage adsorber 'B' showed 100 % removal efficiency for three dialkyl mercury species in liquid hydrocarbon streams. The removal efficiency for adsorber 'C' was species dependent. Two common condensate species gave values of 50 to 80 % removal efficiency while the third species showed time-dependent bleed-off.
