Family-centered care (FCC) is important within the practice of pediatric oncology nurses. Such nurses face challenges and barriers when attempting to provide FCC. The purpose of this study was to understand the experiences of pediatric oncology nurses in relation to FCC; identify how pediatric oncology nurses implemented FCC into their practice; identify what facilitated and enabled pediatric oncology nurses to implement FCC; and discern the barriers and challenges that were present in their setting when implementing FCC. A qualitative approach utilizing person-centered interviewing was used to collect data. Nurses (N=20) from the Alberta Children‟s Hospital were recruited through purposeful convenience sampling and were then interviewed. Five major themes were identified from the data set: ACH support f FCC, How participants defined FCC, Establishing FCC, Enhancing FCC, and Barriers and Challenges to providing FCC. Recommendations for future research and implications for practice and education are offered. / xii, 191 leaves ; 29 cm

Douglas-fir (Pseudotsuga menziesii) and lodgepole pine (Pinus contorta) in southwestern Alberta were studied to determine the water sources used and the effect of changing soil moisture on tree ecophysiological function. The hydrogen stable isotope ratios of water from local groundwater and precipitation were compared to tree stem water to determine the amount of stem water coming from those two sources. There were no significant differences between species in the portion of summer precipitation taken up. However, Douglas-fir shifted towards using more groundwater as shallow soil moisture declined. In addition, Douglas-fir showed large changes in shoot water potential, but maintained relatively constant rates of oxygen evolution, whereas lodgepole pine exhibited smaller changes in shoot water potential and had severely reduced rates of oxygen evolution during mid-summer drought. Lower leaf-area to sap-wood area and higher leaf δ13C (carbon isotope composition) suggested a less efficient hydraulic system in Douglas-fir compared to lodgepole pine. / x, 91 leaves : ill. ; 29 cm

Endocrine disrupting compounds and pesticides have been detected in rivers and irrigation canals of Southern Alberta, a semiarid region with irrigation-dependent crop production, intensive livestock operations, and a growing human population. However, little is known about the effects of agricultural runoff or wastewater treatment plant (WWTP) effluent in Southern Alberta on fish. Reproductive effects of WWTP effluents from the cities of Lethbridge and Medicine Hat, as well as agricultural runoff in the Lethbridge Northern Irrigation District canals, were investigated in a field study with wild fathead minnows (FHMN) in the Oldman and the South Saskatchewan rivers, in Alberta, Canada, and in a laboratory study with laboratory reared FHMN exposed in vivo to the city of Lethbridge WWTP effluent for 21 days. Biochemical and morphological endpoints were measured to characterize reproductive status. Liver vitellogenin, a biomarker of exposure to estrogen mimics, was analyzed using quantitative RT-PCR, and gonadal histology was used to determine sex, gonadal maturity, and intersex. Adverse reproductive effects were detected in FHMN exposed for 21 days to 10 and 25% of Lethbridge WWTP effluent. In the field, effluents from both Lethbridge and Medicine Hat had an effect on the reproductive systems of FHMN. In canals, reproductive effects were detected in wild fathead minnows in years when water quality in irrigation drain canals decreased. Exposure to pesticides was estimated using acetylcholinesterase (AChE) inhibition. Exposure to Lethbridge WWTP effluent did not inhibit AChE, whereas results from the field study were inconclusive. In conclusion, reproductive systems of fathead minnows in Southern Alberta were impacted by anthropogenic chemicals. / xi, 104 leaves : ill. (some col.), maps ; 29 cm

This thesis explores Blackfoot homelessness in relation to traditional attachments to Blackfoot territory. It addresses the underlying causes of Blackfoot homelessness in the city of Lethbridge. It speaks to the participants’ experiences of loss on a multitude of levels, disconnection from family and traditional community, and the complex notion of what “homelessness” means for the Blackfoot participants. The thesis uses a literature review to inform the study. The research methodology is a focused ethnography. Interviews with Blackfoot homeless participants were conducted at the city of Lethbridge’s homeless shelter in 2009 and 2010. Narrative analysis was used to interpret the data and the findings, and the subsequent discussion of them, were from a Blackfoot perspective. It is hoped that the information contained within this thesis will help those reading it to better understand Native homelessness and provide insights into the subjective nature of what it means to be “home.” The results of the findings also suggest ways for service providers to develop improved programming aimed at the Native homeless population. / vi, 164 leaves ; 29 cm

Twenty women linked with the sex trade in Edmonton, Canada went missing or were murdered between 2001 and 2008. In this study, I use Foucauldian and feminist theories, via discourse analysis, to examine the ways that Edmonton’s newspapers (re)present these murders. My findings show that the newspapers’ discourse deviantises these women, thereby minimising the tragedy of their disappearances and deaths. This deviantisation is deployed in three ways; by framing sex trade workers as criminally, medically, and morally deviant. Criminal deviance places sex trade workers firmly on the ‘wrong’ side of the law, making them undeserving of police protection; medical deviance implies that only women who are mentally ill in some way would take part in the sex trade, and, simultaneously, hyperbolises the role of sex workers in the spread of venereal diseases. Finally, discourses of moral deviance place sex workers on the ‘wrong’ side of morality and femininity. iv / ix, 126 leaves ; 29 cm

Eighteen prairie rattlesnakes (Crotalus viridis viridis) were tracked using radio-telemetry and 82 snakes were PIT-tagged over a 2-year period in Lethbridge, AB to determine population size, movement patterns, and habitat utilization, and to predict fragmentation effects on the species within an urban locale. Population size was estimated using closed population models at 374 snakes (295 adults) and open population models at 204 snakes (161 adults), greater than an estimate of <50 adults in 2003 (Ernst, 2003) and 2006 (Ernst & Quinlan, 2006). Mean home range sizes, based on 95% minimum convex polygon analysis, differed significantly between years (31.51 ha in 2005, 3.72 ha in 2006). Calculated movement parameters, such as mean distance moved per day, total distance moved over the course of the active season, and frequency of movement varied between years and individuals. Greater-than-expected (under hypotheses of even habitat choice) utilization was observed in habitat types located within coulee and flood plain areas, with apparent preference towards unbroken parcels of grassland or cottonwoods, whereas less-than-predicted utilization of agricultural habitat type was observed. Fragmentation effects on prairie rattlesnake movement and occurrence were examined through modeling and were found to coincide with observed species’ locations, suggesting that prairie rattlesnakes are undergoing modification of movement patterns to avoid highly concentrated human density or use. Influence of weather on the use of vegetative ground cover was observed, as it was accessed more by prairie rattlesnakes at higher temperatures. Recommendations towards future management of the prairie rattlesnake population in Lethbridge are given, including protection of the Bridge View Drive site and inclusion of varied habitat types and terrain when planning habitat and wildlife corridors. Management decisions that ensure remaining habitat parcels and connective areas near rattlesnake foraging or movement corridors are also advocated. Identification of future research focuses include studies on juvenile survivorship, genetic structure, and vehicle-related mortality. / xii, 83 leaves : col. ill., col. maps ; 29 cm

Accurate estimation of Net Primary Productivity (NPP), which is a key component of the terrestrial carbon cycle, is very important in studies of global climate. Ecosystem models have been used for NPP estimates. Determining how much each source of uncertainty contributes to modeled NPP is veiy important before ecosystem models can be used with confidence over larger areas and time periods. This research has systematically evaluated the boreal ecosystem productivity simulator (BEPS) carbon model in mountainous terrain, Kananaskis, Alberta. After parameterization of the model, sensitivity analysis was conducted as a controlled series of experiments involving sensitivity simulations with BEPS by changing a model input value in separate model runs. The results showed that NPP was sensitive to most model inputs measured in the study area, but that the most important input variables for BEPS were LAI and forest species. In addition, the NPP uncertainty resulting from topographic influence was approximately 3.5 %, which is equivalent to 140 kg C ha"1 yr"1. This suggested that topographic correction for the model inputs was also important for accurate NPP estimation. Using the topographically corrected data, the carbon dynamics were simulated, and average annual NPP production by forests in Kananaskis was estimated at 4.01 T ha"1 in 2003. / xix, 117 leaves : col. ill. ; 29 cm.

Prior to the beginning of the Second World War discussions of air force training between Britain and Canada, were ongoing, but never agreed upon. The declarations of war on Germany from Britain and Canada forced these discussions to a resolution as the air force was a crucial component of military operations. On December 17, 1939 the agreement known as the British Commonwealth Air Training Plan (BCATP) was signed. The agreement intended that Canada would train all of the Allied air force throughout the war. The repercussions of the agreement meant that communities across the country became home to training schools and air force personnel. This study employs geographic and relational aspects of community theory in the investigation of the role of sport in the relationship building process between military and civilian communities in Southern Alberta. Sport provided common ties and opportunities for social interaction in the relationship-building process between BCATP schools and Southern Alberta communities. Towns were losing many of the men and women who were playing sport as they joined the services and air force personnel were replacing them; thereby keeping sport at all levels from completely shutting down during the war. This study highlights the changes in the sporting landscape as military sport transitioned from a spectacle to becoming indispensable to local communities. Specific case studies of basketball and lacrosse in Macleod, hockey in Claresholm and Lethbridge, soccer in Medicine Hat and sporting charity events indicate the depth to which schools integrated into towns through sport. Situated within pertinent secondary sources from history, sociology and sport studies this study draws on six Southern Alberta newspapers, town council meeting minutes and archival data from the Nanton Bomber Museum, The Claresholm Museum, The Galt Museum and Archives and the Esplanade Heritage Centre. / ix, 184 leaves ; 29 cm

Feedlot finishing of beef cattle in Southern Alberta involves income risk due to the variability of prices of feeders, feed and finished cattle. Several strategies are available to reduce this risk, including hedging of cattle on feed, participation in a Federal- Provincial government and producer established income stabilization program for finished cattle (National Tripartite Stabilization Plan) and diversification of production plans. This study evaluated the efficacy and interaction effects of these strategies in reducing net income variability in cattle feeding in Southern Alberta. Concerns that were addressed included: (1) whether participation in hedging or Stabilization would increase firm-level slaughter cattle output, (2) whether portfolio effects exist between production and marketing alternatives, (3) whether participation in Stabilization would reduce participation in hedging (4) whether hedging performance could be increased by hedging the Canadian dollar, and (5) whether privately supplied hedging versus publicly supplied Stabilization is better able to handle income risk in cattle feeding. The theory of decision making under uncertainty was reviewed to determine how to best incorporate the risk aspects of the feedlot , management problem. Expected Value-Variance (EV)and safety-first risk analyses were identified as frameworks for formulation of the feedlot management problem in a mathematical programming context. Using data from 1976-87, linear risk programming (MOTAD and Target MOTAD) models of the feedlot process were constructed to analyze the alternatives for reducing income risk. Results for the 1986-87 feeding year suggested that, at moderate levels of risk aversion, feedlot managers should maintain high levels of hedging of both live cattle and the Canadian dollar with moderate participation (25 percent of cattle on feed) in the Stabilization plan. Significant portfolio effects were present. Hedging, but not Stabilization, was found to increase firm-level output by increasing the average weight to which a group of cattle would be finished. Participation in Stabilization was found to reduce hedging participation by an average of 10 percent. Hedging of the Canadian dollar improved the performance of live cattle hedging. Whether hedging was better at reducing risk and maintaining income than Stabilization depended on the definition of risk. / Graduation date: 1989

This thesis suggests that it is impossible to consider any administrative agency in the abstract without losing important elements of the nature of the legal environment within which the agency operates. There is a large gap between the theories of formal administrative law and the experience of practice in particular administrative settings. Drawing upon the work of sociologist Pierre Bourdieu, the thesis develops the concept of the legal administrative field as a means to approach this issue. The use of Bourdieu's concepts of field, habitus and capital help to articulate and give a theoretical structure to a process and series of practices that are otherwise hard to identify or study. Two Alberta farm marketing boards, and certain specific legal issues faced by each board, are examined in detail and analyzed in terms of the concept of the legal administrative field. It is shown that for each board, the realm of what was 'legally possible' shifted despite the fact that there were no changes in the formal administrative law and that legal practice in these fields involves far more than the application of the principles of formal administrative law. The intersection of the principles and habitus of formal administrative law, the structure provided by the legislative and regulatory framework, and the respective capital and habitus of all the individuals, agents and agencies within the field all interact and these complex interactions are what structure the legal administrative fields and shape the shifts which occur within them. In the struggles of interpretation which occur in these fields an attempt to make a clear demarcation between the practice of law by lawyers and the administration of the system by administrators is inadequate; it simplifies and renders invisible much of the complex series of interactions in which the legal practitioner is a participant and which create the field in which he or she practices. The conclusion is that the heuristic value of the legal administrative field in relation to the legal issues faced by the two marketing boards, and in relation to legal practice in the farm marketing area has been established and that this concept provides a useful perspective and a valuable supplement to a more traditional approach.
