Role of Consumption in Canada’s Economic Sustainability
This thesis addresses the interconnectedness of environmental sustainability and economic sustainability. There is evidence from the Canadian experience that market economies are extremely dependent upon consumption - the most significant factor in determining the overall level of economic activity and economic growth. Therefore, from this perspective, several periods of declining consumption would create a ‘vicious cycle’ [Kaldor, 1967] of economic decline that would be politically unsustainable. The analysis here shows that income inequality drives changes in debt-fueled consumption, and consequently, debt influences consumption. The role of income inequality as a mediating channel of sustainability via the borrowing/lending model presents evidence that ‘conventional’ debt servicing behaviour in the macro-economy can support steady-state economic growth that is, in economic terms, sustainable. Solving the conflict between the environment and the economy lies in private and public investments in new technologies and, most importantly, new social institutions that facilitate economic, political, and environmental, sustainability.

Robust assessment of changes in wild mammal occupancy and activity relative to livestock and human disturbance
Anthropogenic activities such as human activity and livestock grazing are responsible for the global rise in disturbance impacts on wildlife and may underlie regional changes in biodiversity and ecosystem dynamics. Few studies have tried to disentangle the effects of different anthropogenic activities on wildlife behaviour, leaving a major gap in our understanding of conservation and management needs in disturbed areas. Human activity and livestock grazing are increasing in spread and intensity worldwide, thereby imposing pressure on both wildlife and natural areas. In this thesis, I used a camera trapping and occupancy modeling framework to assess whether human presence and livestock grazing had different impacts on site occupancy and activity of 10 wild mammal species, and how responses differed across taxa. Specifically, I predicted that all species would be sensitive to disturbance, but the type and intensity of the response would depend on disturbance type. I detected different responses to each disturbance type across species, but response type (displacement, activity change, crepuscularity) was not associated with species characteristics such as body. Importantly, disturbance intensity had a strong effect on wildlife activity levels, with many species exhibiting marked reductions in activity at high human or livestock disturbance intensity. It remains unclear whether all species’ responses are a direct consequence of disturbance versus indirect outcomes of shifts in behaviour of other species in the wildlife community (i.e., disturbance-related changes in prey activity may affect predator activity). Although on the whole disturbance intensity and effect sizes tended to be relatively low in this study, responses were exhibited across all species, implying that disturbance responses may be universal in wild mammals and largely underestimated. Ultimately, my work offers a template for the robust assessment of disturbance impacts on wildlife and provides new avenues for future research to deepen our understanding of wildlife sensitivity to anthropogenic activities.

Robert Bringhurst and Polyphonic Poetry
Robert Bringhurst states that polyphonic art is a faithful, artistic reflection of the multiplicity of the world’s ecosystems. This ecocritical perspective recognizes that human art informs our understandings of the world, and therefore artists have a moral obligation towards that world. In Chapter One I argue that mimesis should be reclaimed as a useful literary category since all art, regardless of intentions, has an effect on both culture and the natural world. In Chapter Two I argue that by reconnecting publishing craft and philosophy, our books can serve to bring us more in tune with the structures of the natural world. I conclude in Chapter Three by asking how a counterpublic consciousness can be cultivated, and how Bringhurst’s mission of transforming culture might be fully realized. Altogether, this view of literature offers an antidote to Western culture’s destructive tendencies towards the natural world.

Ritual, Social Organization, and Monumental Architecture
New archaeological material was discovered in 2006 by the Göksu Archaeological Project in an area of Southeastern Turkey known as Rough Cilicia. This thesis documents and explores the material remains from funerary contexts at the sites of Dağpazarı and Topkaya. Architectural analysis of the material from Dağpazarı demonstrates that the remains are of a monumental temple tomb dating to the late second or early third century A.D. Although the remains from Dağpazarı are fragmentary, the evidence is examined to suggest possible architectural reconstructions. The examination of the Topkaya tomb cluster sheds light upon an ornately decorated rock-cut temple façade tomb dating the Roman period. Both sets of tombs are stunning examples of monumental architecture from the Roman period in an area that suffers from a lack of surviving architectural material. In order to understand the variation in monumental tomb forms the relationship between death, burial, and monumental architecture is examined from a functional perspective. The rites of passage are used as a theoretical framework for examining the functional role that monumental architecture plays in the performance of funerary ritual and the formation of social organization in Roman Rough Cilicia. Ultimately, it is demonstrated that monumental funerary architecture serves as a physical manifestation of abstract concepts that aid in the performance of the rites of passage associated with death and the funeral. Thus, this thesis highlights how abstract information can be gained from seemingly limit physical remains. Author Keywords: Burial, Monumental Funerary Architecture, Rites of Passage, Roman, Rough Cilicia, Social Organization
Risk of Mortality for the Semipalmated Plover (Charadrius semipalmatus) Throughout Its Life Cycle
Three long-term mark and recapture/resight data sets of individually marked Semipalmated Plovers (Charadrius semipalmatus) were analyzed using Cormack-Jolly- Seber models. Data came from two breeding populations (Churchill, Manitoba, Canada, n=982, and Egg Island, Alaska, USA, n=84) and one overwintering population (Cumberland Island, Georgia, USA, n=62). For Alaska and Georgia, time-invariant models were best-supported, giving annual survival estimates of 0.67 (95%C.I.: 0.58- 0.76) and 0.59 (95%C.I.: 0.49-0.67) respectively. Data from Manitoba supported a timedependent model: survival estimates varied from 1.00 to 0.36, with lowest estimates from recent years, supporting observations of local population decline. Seasonal survival analysis of the Georgia population indicated lower mortality during winter (monthly Φoverwinter: 0.959, 95%CI: 0.871-0.988; for 6 month period Φoverwinter: 0.780 (0.440-0.929)) than during combined breeding and migratory periods (monthly ΦBreeding+Migration: 0.879 (0.825-0.918); for 8 month ΦBreeding+Migration: 0356 (0.215-0.504)). I recommend, based on high resight rates, continued monitoring of survival of wintering populations, to determine potential range-wide population declines.

Ripe for the Taking
This thesis considers the fanfiction genres of slash-fiction, and Alpha/Beta/Omega fiction through an analysis of fandom’s embedded gift economy structures. Previous research on fanfiction and fandom structures have often characterized the gift economy nature of these spaces as countercultural and as separate from the frequent exploitation inherent in economic-based systems. There has been less attention paid to considering the potential disruptions that can come with unregulated and large-scale sharing. This thesis undertakes a critical discourse analysis of Alpha/Beta/Omega slash-fiction with a focus on commodity fetishism to reveal how the subgenre’s relationship with the fanfiction gift economy complicates and at times counters the conception of these spaces as a ‘queer utopia.’ The purpose of this research is to dismantle traditional archetypes within Alpha/Beta/Omega fanfiction by exploring how male Omegan characters become fetishized cultural commodity objects internally through interactions with Alpha characters and externally through the desires of fanfiction readers and writers. Author Keywords: Alpha/Beta/Omega, Commodity Fetishism, Fanfiction, Gift Economy, Queer Theory, Slash-fiction
Rights, Resources, and Resistance
The development of pan-Indigenous political organizations in northeastern Alberta in the context of oil and gas development during the 1970s created disparate effects on Indigenous communities in the region. Resistance to assimilation policies led the Indian Association of Alberta to transform itself into a unified voice that represented Aboriginal and treaty rights in the late 1960s; however, the organization lost legitimacy following the divergence of goals between influential Indigenous leaders, Harold Cardinal and Joseph Dion. Tripartite agreements began to unfold between the federal and provincial governments, the oil and gas industry, and individual local leadership; environmental degradation spread throughout the landscape. Some communities benefitted financially whereas other communities, like Lubicon Lake Nation, received little compensation and felt the full force of industrial contamination of their traditional territories. Without the support of pan-Indigenous political organizations, Lubicon Lake developed an individual response that was successful in gaining international attention to their conditions.

Rewiring the State
ABSTRACT Rewiring the State: The Privatization of Information Technology in the Ontario Public Service (1972-2003) David Rapaport Senior managers in the Ontario Public Service (OPS) and neo-liberal public policy advocates rationalize the privatization of Information Technology (IT) as an organizational quest for new efficiencies, specifically efficiencies imported from market economies. The findings of the research for this study indicate that IT privatization frequently results in inefficiencies, dependencies and a loss of core skills. The explanation for widespread IT privatization must be sought elsewhere. This study researches and depicts two related IT developments. The first development is the evolution of IT privatization from the earlier practice of body-shopping, i.e. the hiring on contract of IT consultants to the more complex public private partnership. This evolution is a reflection of the maturation of privatization. Body-shopping informs the alienation of IT skills from the public sector, the shaping of a labour hierarchy based on skills distribution, and the foundation for the public-private partnership. The second development, the evolution of OPS management attitudes towards IT privatization, is a reflection of growing neo-liberal hegemony. Archival research indicates middle management disdain towards excessive IT privatization in the early 1980's; particularly its high costs, loss of skills and growing dependency on external private sources. By the ii late 1990's, parliamentary committee transcripts indicate IT management acceptance of more excessive IT privatization. As neo-liberal practice became more accepted and as governments and central ministries pressured line ministries through budgetary and organizational controls, IT managers accepted their new roles as authors of RFP's and tenders of public sector work. The IT service providing industry gladly bid on contracts and acquired the new skills required for future IT projects, exacerbating the provision/dependency cycle. Furthermore, the new technologies provided an ideological smokescreen of technological necessity to conceal the market forces that promoted and benefitted from IT privatization. "Why do managers in the Ontario Public Service privatize the production of Information Technology systems?" The dissertation has two tasks when answering this central question. First, it must refute the efficiency arguments. Second, it must formulate an answer within the context of neo-liberal state transformation, new investment strategies of IT service providing corporations and a restructured IT labour hierarchy.

Return to "The Child"
Despite - or perhaps because of - her popularity as a best-selling poet, the work of Mary Oliver has been minimized and marginalized within the academy. Nevertheless, Oliver's readership is an expansive and devout one made up of a wired yet insular North American public in search of reconnecting with the natural world. I propose that through Oliver's poetry readers access the affective, sensory responses to nature first encountered during childhood. This return to "the child" is deliberately used by various publics to share communal goals. Drawing from such frameworks as ecocritical and trauma theory, I explore environmental memory, ecstatic places, and the sensuousness of nature and language to consider ways in which diverse publics claim and use Oliver's work. I provide a close reading of selections of Oliver's poems to argue that her work's appeal speaks to a revived perception of the necessity of nature to the human spirit Author Keywords: Attentiveness, Childhood, Language, Mary Oliver, Nature Poetry, Senses
Retrograde Amnesia of Fear Memories Following Pentylenetetrazol Kindling
Memories pertaining to fearful events are some of the most salient and long-lasting memories, as they are critical to the survival of an organism. Seizures induce aberrant changes within temporal lobe and limbic brain structures that are critical for supporting fear memories. Seizures can occur at any time; therefore, it is imperative that research address how seizures impact previously learned information. The present series of experiments demonstrate that pentylenetetrazol-kindling induces retention deficits of previously acquired context fear memories in male rats. Kindling induced subsequent fear learning deficits but did not impact spatial learning. Additionally, following kindling, volumetric increase was observed within the hippocampal subfield CA3, as well as increased neural activation within the hippocampal subfield CA1. The results of this work suggests that chronic seizures can alter the function of neural networks important for supporting and retrieving previously acquired memories.

Rethinking Subjectivity
The following thesis problematizes different theories of subject formation in relation to morality, accountability, and consciousness raising. Focusing on the conditions subjects emerge in, I argue that socially transformative subjectivities emerge in movement through spaces. The theoretical discussion departs from the premise that morally accountable subjectivities drive social change. The politics of positionality that anchor the subject in a particular social location conceptualize morality as the result of critical consciousness raising. The causal nature of the relationship between the subject’s ability to reflect back on itself and its moral capacity is problematic for it leaves the reflective subject in a position of epistemic and moral authority. Rather, a subject who does not fully know itself nor the conditions of its being has the ability to engage in moral inquiry. Grounding subject formation in epistemic uncertainty construes the subject as inherently accountable to other unknowing subjects. Transformative subjectivities emerge out of epistemic resistance and uncertainty. The particular understanding of morality that underlies the rethinking of my moral subject emanates from its relational constitution. A morality of care prioritizes the responsibilities a subject has to others. In the context of Covid-19, relational subjects act in accordance with a morality of care that leads them to intervene in the lives of others who are threatened by the virus and left unprotected by institutional structures. The desire to interfere is cultivated when subjects emerge in ontological fields generated through epistemic intervention. One way to create such interventions is through counter-hegemonic cultural production such as works of art. Author Keywords:
Responses of Primary Producers and Grazers to Silver Nanoparticle Exposure
The increasing production and use of silver nanoparticles (AgNPs) raise concerns on environmental exposure and impact. A large scale in situ enclosure study was conducted at the Experimental Lakes Area to determine the effect of AgNPs on natural phytoplankton and zooplankton communities. This study investigated AgNPs of varying concentrations (4, 16 and 64 μg/L), dosing regimens (chronic vs. pulse), and capping agents (poly-vinyl pyrrolidone vs. citrate). Phytoplankton communities were influenced only by the natural limnological properties of the system signifying tolerance to AgNPs. Zooplankton community structure significantly changed with AgNP concentration and dosing regimen indicating AgNP sensitivity. A microcosm study investigating the effect of AgNPs and phosphorus-dosed periphyton before and after grazing by two benthic invertebrate species (snails and caddisfly larvae) showed reduced periphyton stoichiometry with AgNP exposure. Grazers foraged less on silver dosed periphyton indicating a preferential choice in food quality. Phosphorus reduced the detrimental effects of AgNPs across all conditions. These studies verify the need for in situ experimental designs to fully investigate the effects of AgNPs and their interaction with environmental factors, multiple species assemblages, and across trophic levels. Author Keywords: benthic invertebrate, Experimental Lakes Area, periphyton, phytoplankton, silver nanoparticles, zooplankton
