The purpose of this exploratory, mixed method study was to examine factors in students‟ university experiences that affected their future alumni engagement with their university. A web-based survey instrument was administered to 1,139 University of Lethbridge bachelor‟s degree holders who graduated during the University‟s first 40 years (1967 to 2007). Results indicate that the foundation for alumni engagement is set early in the student experience and is particularly affected by the nature of the relationships the student has with the institution. Alumni who were engaged as students were more likely to become engaged alumni through volunteer or donor activity. The higher alumni rated their satisfaction with factors present in their student experience and alumni relationship, the higher the likelihood that they stayed connected with and demonstrated their commitment to their alma mater. Recommendations for further research and for designing student and alumni engagement strategies are provided. / xiv, 195 leaves ; 29 cm

The Fincastle Bison Kill Site (DlOx-5), located approximately 100 km east of Lethbridge, Alberta, has been radiocarbon dated to 2 500 BP. Excavations at the site yielded an extensive assemblage of lithics and faunal remains, and several unique features. The elongated point forms, along with the bone upright features, appeared similar to those found at Sonota sites within the Dakota region that dated between 1 950 BP and 1 350 BP. The relatively early date of the Fincastle Site prompted a re-investigation into the origins of the Besant Culture. The features, faunal and lithic assemblages from twenty-three Late Middle Prehistoric sites in Southern Alberta, Saskatchewan, Montana, Wyoming, and the Dakotas were analyzed and compared. The findings show that Fincastle represents an early component of the Besant Culture referred to as the Outlook Complex. This analysis also suggests a possible Middle Missouri origin of the Fincastle hunters, as well as the entire Besant Culture. / xii, 183 leaves : ill. (chiefly col.) ; 29 cm

Canada's declaration of war in 1939 resulted in the creation of a "total war" economy that necessitated the absorption of all available men, and led to the wide scale recruitment of women into the military and labour force. The end of the war resulted in government and media encouragement to return to the home, but despite this emphasis on home and family, many women developed a two-phase work history. In this thesis, I use the oral history of sixteen Southern Alberta women to analyze the effect of World War II on Southern Alberta women's work and family choices, focusing specifically on the years between 1939 and 1959. I argue that, although the war did not significantly change the status of women in the paid workforce, it did affect the geographic mobility of women and the perception of their own work, both paid and unpaid. / vi, 181 leaves ; 29 cm.

Continuous eddy covariance measurements were conducted for a 125 day period, throughout the 2007 growing season, in a northern Alberta peatland. Significant diurnal and seasonal variation in methane fluxes were observed. Diurnal variation in methane flux was suggested to be due to variation in soil temperature and methane convective flow through vegetation to the atmosphere. Seasonal variation in methane flux was associated with a variety of factors, most notably seasonal variation in the capacity for methane emission at 10 ºC (R10). The R10 values varied as a function of soil temperature and were an important control of seasonal variation in methane flux. Also, a greenhouse gas budget was calculated comparing net methane emission and net CO2 sequestration. This analysis indicated that the peatland was acting as a net sink of radiative forcing agents for the 2007 growing season. / xiii, 100 leaves ; 29 cm. --

Strong seasonality is observed in the volatile hourly Alberta temperature and its low- and high-order statistical moments. We propose a time series model consisting of a linear combination of an annual sinusoidal model, a diurnal sinusoidal model and a fractional residual model, to study the characteristics of these spatial and time-dependent Alberta temperatures. Wavelet multi-resolution analysis is used to measure Hurst exponents of the temperature series. Our empirical results show that these Hurst exponents vary over various time scales, indicating the existence of multi-fractality in the temperatures. Such temperature models are of importance for the pricing and insurance of agricultural crops, of tourist resorts and of all forms of energy extraction and generation of importance to the resource-based economy of Alberta. Of particular interests are the observed extreme volatilities in the winters, caused by the unpredictable Chinook winds, which may be an important reason to introduce a Chinook insurance option. / 64 leaves : map ; 29 cm

Freshwater and terrestrial ecosystems are connected through biomass exchanges such as the flow of predators, prey, nutrients and detritus between them. Emerging aquatic insects provide an alternate food source to riparian consumers often termed an allochthonous subsidy. Stable isotope analyses of naturally occurring carbon and nitrogen is effective for tracing energetic food sources to consumers. This thesis evaluated whether stable isotope analysis would be effective in the Oldman River Basin, Alberta. Aquatic and riparian primary consumers are distinct in their isotopic signatures and valid for to use in stable isotope analysis. Stable isotope modelling was then used to evaluate the proportional contribution of aquatic insects to riparian spider and beetle diets. Carbon analysis showed an overall aquatic insect contribution of 25 % and 18 % for spiders and beetles, respectively; while nitrogen analysis showed an overall contribution of 36 % and 20 %, respectively. The spatial extent of the aquatic insect contribution upland from the river was shown to decrease from 50 - 55 % at 1 m to 0 % at 30 m for both consumers using carbon, and from 35 - 40 % at 1 m to 0 % at 40 m using nitrogen. Finally, regression modelling of the size of a river and the spatial scale of an aquatic insect dietary contribution showed a significant relationship, indicating larger water bodies support higher production of aquatic insects. A meta-analysis of published literature applied to this model also indicated a significant relationship between the size of the river and the extent of an aquatic insect contribution. / xii, 126 leaves m ; 29 cm

The report presents an implemention of a classification algorithm for the Institutional Analysis Project. The algorithm used in this project is the decision tree classification algorithm which uses a gain ratio attribute selectionmethod. The algorithm discovers the hidden rules from the student records, which are used to predict whether or not other students are at risk of dropping out. It is shown that special rules exist in different data sets, each with their natural hidden knowledge. In other words, the rules that are obtained depend on the data that is used for classification. In our preliminary experiments, we show that between 55-78 percent of data with unknown class lables can be correctly classified, using the rules obtained from data whose class labels are known. We feel this is acceptable, given the large number of records, attributes, and attribute values that are used in the experiments. The project results are useful for large data set analysis. / viii, 38 leaves ; 29 cm. --

This research involves an examination of the olfactory ability of individuals with Frontotemporal Dementia, Alzheimer's disease, and geriatric individuals with cognitive complaints owing to Major Depressive Disorder or Generalized Anxiety Disorder. The purpose of this study was to determine if olfactory differences were useful in differentiating between demented and non-demented individuals. Due to the pathway of the olfactory tract, it can be expected that there would be equal olfactory deficits in those diagnosed with Frontotemporal Dementia and Alzheimer's disease, and that these deficits would be worse than those found in geriatric individuals with Major Depressive Disorder or Generalized Anxiety Disorder. Five hypotheses were investigated. The first utilized an ANCOVA and found that the olfaction of the demented group was worse than that of the non-demented, psychiatric group. The second utilized a series of Discriminant Function Analyses and F-tests and determined that olfaction best classified demented and non-demented individuals. The third implemented a Mixed Model ANOVA to assess for lateralized smell deficits within the demented group and between the demented and non-demented groups and found no main effects of lateralization or interaction effects. The fourth hypothesis investigated the relationship between smell and commonly used neuropsychological tests in a Frontotemporal Dementia sample, and found that there was no difference between the relationship of tests measuring the frontal and temporal lobes to those measuring other cerebral areas. The fifth hypothesis replicated Hypothesis 4 in an Alzheimer's disease sample and found that there was a significant difference between the relationship of tests measuring the frontal and temporal lobes to those measuring other cerebral areas. Primarily, this study demonstrated that dementia patients present with significantly more olfactory deficits than a psychiatric sample with subjective cognitive complaints. Additionally, olfaction correctly distinguished the Dementia Group from the Psychiatric Group with 81.6% accuracy, 90.2% sensitivity and 67.6% specificity. Alone, these classification statistics are quite impressive, appearing equivalent, or possibly superior to the classification statistics of commonly used neuropsychological tests of memory, executive functioning, and visuospatial ability. This study concluded that adding an olfactory measure to an assessment battery provides clinically relevant data, and enhances the diagnostic accuracy of the battery. However, though this study found the Alberta Smell Test was a valuable addition to a test battery, the absence of lateralized findings demonstrated the unirhinal format, by which the Alberta Smell Test is administered, does not provide diagnostically relevant information above and beyond the information a clinician will gain from birhinal assessment.
