This thesis presents the results of a general geological study of a belt of Archean rocks in the Indin Lake district, N.W.T. The summary results of a summer's field work are incorporated with a brief petrographical investigation of different rock types. Intermediate to acidic lava flows and pyroclastic rocks overlain conformably (?) by a succession of clastic sediments are invaded by minor acidic intrusives and a plexus of basic dykes and sills. Isoclinal folds in sediments, broader flexures in volcanics, bedded shear zones, and regional foliation and lineation are all attributed to a single system of powerful tangetial forces that affected all stratiform rocks in the area. Zones of weakness at contacts are imputed, to differential competence between volcanic and sedimentary rocks, and a. theory of folding of rock units of differing competency is applied in modified form to the origin of the Indin "break" - a gold-bearing shear zone close to a major contact. Evidence is presented to suggest that “cross-faults” clean-cut dislocations that transect the regional structural trend - and emplacement of late basic intrusives are quasi-contemporaneous events that progressed over a protracted interval of time and may have been consequent upon a single deformational-pattern. An attempt to explain the propinquity, and thus the possible structural relation, of gold mineralization to cross-faults is embodied in a theory relating the control of mineralization "by channeling of ore-solutions in structures developed during the period of strain accumulation that culminated in cross-faulting. An almost completely reconstituted mineral assemblage is ascribed to a moderate grade of regional metamorphism consisting of dynamic metamorphism during orogeny and relatively minor effects of superimposed thermal and retrograde metamorphism. Metacrysts of ankeritic carbonate, believed to be hydro-thermal, are discussed, and their superficial genetic or structural association with gold mineralization is offered as a possible guide to future ore discovery. Rather detailed descriptions are submitted of ankeritic carbonate, an unusual "hornblende" occurring in amphibolite, and a green mica, tentatively called phengitic-muscovite, from a carbonate zone. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

Over the past decade, feeder cattle backgrounders in the Pacific Northwest have been subject to sharp price fluctuations for their output. The result has been variable profits and losses. This situation creates a need for management and marketing techniques which can provide Pacific Northwest cattle ranchers with protection against price risks while enhancing the profitability of their operations. Recent economic literature has shown hedging with futures contracts to be an effective tool for mitigating risk and/or increasing the net revenues of cattle producers in a number of regions of the United States. The objective of this research was to determine whether hedging with futures contracts could have increased the profitability of Pacific Northwest feeder cattle production while decreasing the effects of price volatiliy. To realize this objective, the economic performance of alternative hedging strategies were evaluated for several methods of feeder cattle backgrounding indigenous to the Pacific Northwest region. Four hedging strategies -- routine, moving average, profit objective, and triangular probability distribution — were evaluated for hedging the output of four simulated production systems. The mean and standard deviation of annual net returns were computed for each hedging strategy to serve as measures of profitability and risk, respectively. The results of not hedging were also obtained to provide a basis for comparing alternative hedging programs. Sample t and F tests were conducted to determine whether there were statistically significant differences between the means and standard deviations of the unhedged and hedged positions. Dominant hedging strategies were then identified for each production system. Based on the results of the mean-variance analysis, it appears that the use of selective futures market hedging strategies would have provided greater and more stable levels of profit compared to the net incomes obtained without hedging. Sample t and F tests, using 80 and 90 percent levels of significance respectively, showed that hedging could have significantly decreased the variability of the producer's flow of income without significantly changing the operation's average profitability. Moving average, profit objective, and triangular probability distribution strategies were dominant, increased average profitability, and significantly lowered risk for at least one production system each. Overall, moving average strategies generated the highest mean profits with the greatest risk. Profit objective strategies generally resulted in lower mean profit than moving average strategies but with less risk. The risks and returns from hedging with triangular probability distribution strategies were usually between the moving average and profit objective procedures. Strategies which performed well in this study should also perform well in the future if conditions in the feeder cattle markets do not vary substantially from those of the previous decade. Thus, hedging with futures market contracts may provide the Pacific Northwest feeder cattle producers with protection against price risk and enhanced profitability. / Graduation date: 1985

In Canada's Northwest Territories nurses work primarily with and in First Nations' isolated and semi-isolated communities and are expected to practice at an advanced level. Collaboration is one competency standard identified by the Canadian Nurses Association as necessary for advanced practice. The notion that collaboration competency can be understood as a standard by which advanced nursing practice is defined becomes problematic when culture, language, and unique situations surrounding health in northern communities impact on nursing practice. This research explores and describes how northern nurses experience, understand, and engage in collaboration in their practice and endeavors to bring to light the contextual influences that impact collaborative northern nursing practice.

The objective of this study was to ascertain the magnitude and distribution of rainfall over coastal waters of the northwestern United States and to compare values with those at nearby land stations. Precipitation was measured with gauges at Totem, rainfall amounts were assessed from weather reports at lightships off the coast, and precipitation frequencies at lightships and land stations were examined. Results from the three methods were quite consistent; precipitation. on at sea was only about one-third that at coastal land stations. These values are appreciably less than previous estimates of oceanic rainfall in this area, and they support the view that a significant horizontal gradient of precipitation may exist between the coast and open sea. Rainfall typically occurs both at sea and ashore on the same day, but it rains fewer hours at sea. The relative amount of rain at sea varies with the type of atmospheric system, and rainfall at the coast appears to be intensified by frictional processes. Estimates of evaporation minus precipitation are less negative than earlier ones; consideration of their relation to surface salinity leads to distributions that are in good agreement with oceanographic knowledge. The newer values suggest that in this region the heat gain by the atmosphere may be less (but moisture entrainment may be greater) than was thought. / Graduation date: 1973
