Politics of Muslim Intellectual Discourse in the West
The dissertation explores and defends the theory and practice of a Western-Islamic public sphere (which is secular but not secularist and which is Islamic but not Islamist), within which a critical Islamic intellectual universe can unfold, dealing hermeneutically with texts and politically with lived practices, and which, moreover, has to emerge from within the arc of two alternative, conflicting, yet equally dismissive suspicions defined by a view that critical Islam is the new imperial rhetoric of hegemonic orientalism and the opposite view that critical Islam is just fundamentalism camouflaged in liberal rhetoric. The Western-Islamic public sphere offers a third view, arising from ethical commitment to intellectual work, creativity, and imagination as a portal to the open horizons of history.

Assessing the Effects of Brief Interventions on Mood and Dream Imagery in Recovering Alcohol and Drug Addicts
Addiction can lead to a plethora of health, social and economical problems. Substances are used for mood regulation, and therefore, waking day mood is extremely important during recovery of alcohol and drug addiction. The current study examined the effects of Meditation and Sleep Mentation Therapy on mood levels. All participants were male, and currently in treatment programs or early stages of recovery from alcohol and drug addiction. Participants were tested for anxiety and depression and were asked to provide a recent dream, prior and post to participating in the intervention. Dreams were scored using Hall and Van de Castle guidelines for scoring imagery. Results are consistent with previous research in that mood levels changed over the course of the meditation period. Implications for future research are discussed as well as applications of Sleep Mentation Therapy and Meditation in clinical and applied practice. Author Keywords: Addiction, Dream Therapy, Meditation, Mood
Battle of Maldon
The Battle of Maldon: A Medieval Screenplay History and Heroism in the Cinematic Adaptation of an Old English Poem The Battle of Maldon is an artistic representation of a historical event whose style lends itself to being adapted into a screenplay. This project examines how the poem presents a recent event in an epic heroic style, mixing history with legend, and how the heroism of the men in the poem is celebrated. These explorations lead to the creation of a screenplay which imitates the ways that the poet combines fact and fiction and situates the screenplay within the larger realm of medieval film. Author Keywords: Anglo-Saxon history, Byrhtnoth, film, heroism, Maldon, The Battle of Maldon
Reshaping the Terms of Debate
The Reagan era instigated a fundamentally conservative shift in the political, economic and discursive climate of America. As Ronald Reagan is a highly divisive symbolic figure in American politics, much of the historiography of his presidency has been characterized by polarized interpretations. Over the past decade there has been a noticeable shift towards more favourable and triumphal interpretations of the Reagan era. This thesis seeks to analyze the ideological shifts that have characterized the trajectory of historical writings on the Reagan era. Through employing a careful textual analysis of key works by Michael Schaller, Gil Troy and Sean Wilentz, amongst others, this study demonstrates how historiography serves us less as an objective means of understanding the past and more so as an expanding collective historical artifact that illustrates the changing currents of intellectual and political discourse. In doing so, the notion of scholarly objectivity itself is thrown into question. Author Keywords: Cold War, Conservatism, Historiography, Neoliberalism, Reagan Doctrine, Ronald Reagan
Nutritional stoichiometry and growth of filamentous green algae (Family Zygnemataceae) in response to variable nutrient supply
In this study, I investigate the effects of nitrogen (N) and phosphorus (P) on the nutritional stoichiometry and growth of filamentous green algae of the family Zygnemataceae in situ and ex situ. I found a mean of Carbon (C):N:P ratio of 1308:66:1 for populations growing in the Kawartha Lakes of southern Ontario during the summer of 2012. FGA stoichiometry was variable, with much of the variation in algal P related to sediment P (p < 0.005, R2 = 0.58). Despite large variability in their cellular nutrient stoichiometry, laboratory analysis revealed that Mougeotia growth rates remained relatively consistent around 0.28 day-1. In addition, Mougeotia was found to be weakly homeostatic with respect to TDN:TDP supply (1/HNP = 0.32). These results suggest that FGA stoichiometry and growth rates are affected by sediment and water N and P. However, they will likely continue to grow slowly throughout the summer despite variable nutrient supply.

Changes to the Arctic and sub-Arctic climate are becoming increasingly evident as it warms faster than other areas of the globe, supporting evidence that predictions of future warming will be amplified due to positive feedback mechanisms. The Southern Hudson Bay polar bear (Ursus maritimus) subpopulation is one of the most southerly subpopulations in the world, putting it at increased risk due to effects of climate change. Whereas many other subpopulations have been the subject of intense research and monitoring, little research has been completed detailing the movement behaviour and space use of bears within Southern Hudson Bay. I used detailed movement data collected on female polar bears to establish a baseline of movement information for this subpopulation to which future work can be compared and effects of climate change can be assessed I evaluated the use of core areas during critical periods of the year (breeding and ice breakup) and evaluated common space use as a means of assessing site fidelity during the breeding season. Movement rates and home range sizes were comparable to those of the neighbouring Western Hudson Bay subpopulation. I also found evidence of increased occurrences of long distance, late fall movements along the coast to the northwest, presumably to gain earlier access to first ice. Though space use analysis did not reveal evidence of site fidelity to specific breeding areas in Hudson Bay, I found that core use areas are at risk of substantially shortened ice duration (x¯ =76 days shorter) using projected ice data based on the high emissions A2 climate change scenario.

Early Responses of Understory Vegetation to Above Canopy Nitrogen Additions in a Jack Pine Stand in Northern Alberta
Abstract Early Responses of Understory Vegetation After One Year of Above Canopy Nitrogen Additions in a Jack Pine Stand in Northern Alberta Nicole Melong Nitrogen (N) emissions are expected to increase in western Canada due to oil and gas extraction operations. An increase in N exposure could potentially impact the surrounding boreal forest, which has adapted and thrived under traditionally low N deposition. The majority of N addition studies on forest ecosystems apply N to the forest floor and often exclude the important interaction of the tree canopy. This research consisted of aerial NH4NO3 spray applications (5, 10, 15, 20, 25 kg N ha-1yr-1) by helicopter to a jack pine (Pinus banksiana Lamb.) stand in the Athabasca Oil Sands Region (AOSR) in northern Alberta, Canada. The main objective was to assess the impacts of elevated N after one year of treatment on the chemistry of understory vegetation, which included vascular plants, terricolous lichens, epiphytic lichens and a terricolous moss species. Changes in vegetation chemistry are expected to be early signs of stress and possible N saturation. Increased N availability is also thought to decrease plant secondary compound production because of a tradeoff that exists between growth and plant defense compounds when resources become available. Approximately 60% of applied N reached the ground vegetation in throughfall (TF) and stemflow (SF). Nitrate was the dominant form of N in TF in all treated plots and organic N (ON) was the dominant form of N in SF in all plots. The terricolous non-vascular species were the only understory vegetation that responded to the N treatments as N concentration increased with increased treatment. Foliar chemistry of the measured epiphytic lichens, vascular species, and jack pine was unaffected by the N treatments. Based on biomass measurements and N concentration increases, the non-vascular terricolous species appear to be assimilating the majority of TF N after one year. Vegetation from the high treatment plot (25 kg N ha-1yr-1) was compared to a jack pine forest receiving ambient high levels of N (21 kg N ha-1yr-1) due to its proximity to Syncrude mining activities. Nitrogen concentrations in plant tissues did not differ between the two sites; however, other elements and compounds differed significantly (Ca, Mg, Al, Fe). After one year of experimental N application, there were no environmental impacts consistent with the original N saturation hypothesis.

Effect of Water Surface Simulated Rain Drop Impacts on Water to Air Chemical Transfers of Perfluorinated Carboxylic Acids (PFCAs)
Perfluorinated carboxylic acids (PFCAs) are anthropogenic environmentally ubiquitous surfactants that tend to concentrate on water surfaces. This investigation looked at the effect of simulated rain on the atmospheric concentration of a suite of PFCAs (C2 - C12) above the bulk water system. Increased air concentrations of all PFCAs were detected during simulated rain events. Long chain PFCAs (>C8) were found to be much more concentrated in the air above the bulk water system than their short chain counter parts (
Habitat use and community structure of grassland birds in southern Ontario agro-ecosystems.
Most grassland bird populations are in decline, so it is becoming increasingly important to understand how they use agricultural field types and form their communities. I performed point counts in cultural meadow, intensive agriculture, and non-intensive agriculture areas in 2011 and 2012. Generalized linear models were used to determine the habitat relationships of six focal species. I found that non-intensive agriculture was used most often and intensive agriculture was often avoided, but there were exceptions which indicate habitat use can be species-specific. I determined in which habitats competition was likely occurring and which species pairs were competing in 2011. In 2012, I experimentally tested these relationships by introducing artificial competitors onto sites. By comparing presence-absence data from 2011 to 2012, I found evidence of habitat-mediated interspecific and conspecific attraction involving Bobolink and Grasshopper Sparrow. This research contributes to the current understanding of grassland bird community ecology and conservation.

Why do landowners restore wetlands? A case study from east central Ontario
Wetlands were once widespread in southern Ontario, but many have been drained through land use changes. Using a case study of twelve landowners in the Kawartha region, I explored motivations for restoring wetlands. Psychological research suggests that people who are more connected to nature and attached to place are more likely to behave sustainably. Results showed that having land available and receiving funding were necessary preconditions. Connectedness to nature and place attachment were motivations, as were personal benefits and having a supportive social community. Challenges included: the Permit to Take Water, paperwork and bureaucracy, delays and timing, and economic restrictions. Positive outcomes were: increased property value and crop productivity; personal enjoyment of wetlands; and improved wildlife habitat and water quality. Negative outcomes were: `nuisance' wildlife, trespassing, and a lack or excess of water. This is a novel study exploring nature connectedness, place attachment and wetland restoration qualitatively in southern Ontario. Author Keywords: agriculture, connection to nature, motivation, southern Ontario, stewardship, wetland restoration
This study demonstrates that the New Brunswick government rationalized the 2011 elimination of the New Brunswick Advisory Council on the Status of Women (NBACSW) by discursively framing it as a duplication of services and as a non-essential service. The study relies on interviews with women who had been involved with the NBACSW, as well as literature about the use of neoliberal and anti-feminist discourses at the national level. I argue that the two rationalizations offered by the New Brunswick government rely on similar neoliberal and anti-feminist discourses to those used at the national level to eliminate women's institutional machinery and thus diminish women's capacities for advocacy and political representation. I argue that this discursive move positioned the province's largest women's advocacy group as an impediment to the common good of the province and as a threat to "Ordinary New Brunswickers," signalling a negative step for women in the province.

Commonality of Enemies
Carlism and anarchism were revolutionary social movements that acquired significant popular support during the most intensive period of modernization in Spain (mid 19th to mid 20th centuries). It was noted but not well explored by contemporaries and historians that these enemies were similar in their hostility towards modernization and in their intense idealism. This thesis compares the two movements in order to determine the nature of their commonality and what this suggests about ideological enemies. A range of sources were consulted, including scholarship on modern Spain, biographical information on individuals who converted from Carlism to anarchism and contemporary print media. It was concluded that they were produced by the same destabilizing processes of disentailment and industrialization, which drew the working classes towards proposals that would have otherwise seemed implausibly utopian. The thesis further suggests that they were uniquely idealistic, in that they put moral integrity before the success of their cause. Author Keywords: anarchism, Carlism, enemy other, modernization, Modern Spain, social movements
