On (Digital) Photographic Image-Objects
On the first page of the much read, Camera Lucida, Roland Barthes reveals his motive: “I was overcome by an “ontological” desire: I wanted to learn at all costs what Photography was “in itself,” by what essential feature it was to be distinguished from the community of images.” The impetus of this thesis might be called a Barthesian desire to learn what distinguishes digital photographic images from all other photographic images. Throughout, I ask: what is a digital image? The first exploratory turn reflects upon photographs and touch. While photographs are objects that are both touched and touching, digital images are inscrutable data assemblages that resist touch and are predisposed to speed. Digital images cannot be touched, yet are responsive to touch. Through the mediating magic of touch sensitive glass, we command digital images to move. Chapter two considers prevailing late twentieth century theory on the digital photograph that claims the eclipse of film by digital imaging will render [digital] photographs totally unreliable documents. The results have been surprising; although suspicion about digital image bodies has crept into the cultural psychological fabric, I argue that we still believe in the basic veracity of [digital] photographic images. Finally, I turn my attention to the objecthood of digital imageobjects in a discussion of the widely unacknowledged materiality of data. Digital image-objects—those speedy, untouchable, dubious, things—are heavy. The weight of their bodies moving in the vast—unseen—global technological infrastructure is the burden of my final reflection. Author Keywords: death of film, digital materiality, digital photographic realism, ontology of the image, philosophy of photography, photography after photography
Understanding the Role of Lived Experience in Community Leaders’ Vision and Governance of Economic Development and Sustainability in Rurally Situated Small Cities
Sustainable development is normative - making decisions in the present that construct the experience of place for the future. It is primarily driven by global measures developed to meet the needs of the present while ensuring future generations can meet their own needs. These measures attempt to balance economic prosperity, social justice, and environmental stewardship in many nations. This attempt to balance a plurality of outcomes creates socio-political tensions in choosing between alternatives. These barriers and tensions are characterized through the neoclassical vision of: economics as a science, utility maximization, and alienation of people. This thesis explores the lived experience of community leaders in Peterborough, Ontario as they navigate a contentious and current debate of where to relocate a casino in the region. The results focus on the tension experienced by community leaders as they seek to balance elements of care, while preserving neoclassical values of growth, individualism, freedom of choice, and interconnectedness. The thesis concludes with a model that works towards an understanding of the role of lived experience in economic development decision-making in rurally situated small cities, and recommendations for further research and policy recommendations.

Relationships between Dissolved Organic Matter and Vanadium Speciation in the Churchill River, MB and the Mackenzie River Basin, NWT using diffusive gradients in thin films (DGT)
This study examines the influence of dissolved organic matter (DOM) on dissolved vanadium (V) speciation in the Churchill River and Great Slave Lake using diffusive gradients in thin film (DGT). Vanadium is commonly found in natural environments such as rivers, lakes and oceans. It regulates normal cell growth, but in excessive amounts, it can have toxic effects on human and aquatic organisms. The use of in situ, time integrated DGT devices allows to better (1) monitor the most bioavailable fraction of V, the DGT-labile V, in Arctic Rivers and (2) assess the influence of DOM on dissolved V speciation. Higher DGT-labile V was found in the the central regions of the Mackenzie River (MR), with an average of 7.7 ± 2.3 nM, likely due to sediment leaching and permafrost thawing. The Churchill River and Great Slave Lake (GSL) showed lower DGT-labile V levels (2.2 ± 1.6 nM and 3.6 ± 2.7 nM, respectively), compared to central regions in MR. The CR DGT-labile V concentrations was positively correlated to protein-like DOM concentration and abundance (r = 0.3, p < 0.05). The data collected from this study will help in developing new strategies regarding environmental health and impact assessments of environmentally hazardous waste that consist of potentially high levels of toxic vanadium species. Developments in the use of DGT devices as a sampling method will also aid in future studies involved in analyzing environmental health and specifically dissolved V species in natural waters.

Lipid-derived Thermoplastic Poly(ester urethane)s
Thermoplastic poly(ester urethane)s (TPEU)s derived from vegetable oils possess inferior physical properties compared to their entirely petroleum-based counterparts due to the structural limitations and lower reactivity of the precursor lipid-derived monomers. The present work shows that high molecular weight of TPEUs with enhanced performance can be obtained from lipid-derived monomers via (i) the synthesis of polyester diols with controlled molecular weights, (ii) the tuning of the functional group stoichiometry of the polyester diols and the diisocyanate during polymerization, (iii) the degree of polymerization (iv) the control of the hard segment hydrogen bond density and distribution via the use of a chain extender and (v) different polymerization protocols. Solvent-resistant TPEUs with high molecular weight displaying polyethylene-like behavior and controlled polyester and urethane segment phase separation were obtained. Structure-property investigations revealed that the thermal transition temperatures and tensile properties increased and eventually plateaued with increasing molecular weight. Novel segmented TPEUs possessed high phase separation and showed elastomeric properties such as low modulus and high elongation analogous to rubber. The response of the structurally optimized TPEUs to environmental degradation was also established by subjecting the TPEUs to hydrothermal ageing. TPEUs exhibited thermal and mechanical properties that were comparable to commercially available entirely petroleum-based counterparts, and that could be tuned in order to achieve enhanced physical properties and controlled degradability.

Conservation genetics of Redside Dace (Clinostomus elongatus)
Recent range reductions of endangered species have been linked to urban development, increased agricultural activities, and introduction of non-native species. I used Redside Dace (Clinostomus elongatus) as a focal species to examine the utility of novel monitoring approaches, and to understand historical and contemporary processes that have influenced their present distribution. I tested the efficacy of environmental DNA (eDNA) to detect Redside Dace, and showed that eDNA was more sensitive for detecting species presence than traditional electrofishing. Parameters such as season, number of replicates, and spatial versus temporal sampling need to be accounted for when designing an eDNA monitoring program, as they influence detection effectiveness and power. I also assessed the species’ phylogeographic structure using both mitochondrial and microsatellite DNA analysis. The data from the microsatellite markers indicate that Redside Dace populations are genetically structured, with the exception of several populations from the Allegheny River basin. Combined sequence data from three mitochondrial genes (cytochrome b, ATPase 6 and ATPase 8) indicated that Redside Dace persisted within three Mississippian refugia during the last glaciation. Secondary contact between two lineages was indicated by both mitochondrial and microsatellite data. The combined results from the eDNA and conservation genetics studies can be used to inform Redside Dace recovery efforts, and provide a template for similar efforts for other aquatic endangered species.

Lacanian Realism
The overarching argument of this manuscript concerns Lacanian Realism, that is, the Lacanian theory of the Real. Initially, my argument may seem quite modest: I claim that Lacanians have been preoccupied with a particular modality of the Real, one that insists on interrupting, limiting, or exceeding the various orders or agencies of the human mind. The implications of such a position are worth considering. For example, one must, as a consequence of holding this position, bracket questions pertaining to Things outside of the Symbolic and Imaginary psychical systems. Careful study shall expose the extent to which this position has infuenced each of the major felds inspired by Jacques Lacan: clinical psychoanalysis, radical political philosophy, and mathematics or topology. My task has been to explore the consequent occlusion which psychoanalysis has suffered in each of these three felds and to tease out the possibility of a return to the Real.

Phylogeography and Genetic Structuring of Moose (Alces alces) Populations in Ontario, Canada
Moose are an iconic species, known for their large size and impressive antlers. Eight subspecies are classified in circumpolar regions of the planet - four in North America. Two subspecies are similar in shape and size, the north-western moose (Alces alces andersoni) and the eastern moose (Alces alces americana). It was previously believed that these two subspecies meet in northern Ontario. Earlier genetic population studies used a small number of samples from Ontario, primarily in broad studies covering all of North America. A comprehensive genetic study of moose populations in Ontario has not previously been conducted. We examined the genetic diversity and population structure at 10 polymorphic loci using 776 samples from Ontario, as well as outgroups from representative populations – Manitoba/Cape Breton, representing A. a. andersoni, and New Brunswick/Nova Scotia, representing A. a. americana. Results indicated three genetic populations in the province, in north-western Ontario, north-eastern Ontario and south-central Ontario. RST values, compared against both FST and Jost’s D values for phylogenetic analyses, indicated no phylogenetic pattern which suggests no subspeciation present in the province. Population movement patterns in Ontario were studied. Gene flow was estimated using genetic and spatial data. Isolation by distance was only seen within the first distance class of 100 kilometres and then not seen again at further distances, indicating that moose display philopatry. There were very few migrants travelling across the province, with a greater number moving gradually north and west, towards better habitat and food sources. A forensic database in the form of an allele frequency table was created. Three loci showed very low levels of heterozygosity across all three populations. Probability of identity was calculated for the three populations and quantified. Samples with known geographic origins were run against the database to test for sensitivity, with identification of origin occurring at an accuracy level between 87 and 100%. Within Ontario, there are not two different subspecies, as previously believed, but two different populations of the same subspecies meeting in northern Ontario. The genetic data does not support previous research performed in Ontario. The sample sizes in our research also provide a more comprehensive view of the entire province not seen in any previous studies. The comprehensive research enabled the building of a reliable forensic database that can be used for both management and forensic purposes for the entire province.

Time, Being, and the Image
The three projects that make up this dissertation try to articulate an ontological idea of art; which is to say, they all approach art, or the imagination (as in project two), from the standpoint of a philosophical question concerning the sense of being. The ontological question is elaborated in terms of a theory of the spatial-temporal structure of the aesthetic or sensible realm. This kind of ontology contrasts with a more traditional metaphysical one, where the sense of being is sought within the purely intelligible realm, a realm that transcends the sensible. In projects one and two, the contrast is developed in terms of the Nietzschean/Heideggerian critique of metaphysics, and through the work of Jean-Luc Nancy, who appropriates this critique. In project three, it is developed in terms of Bergson and Deleuze’s critique of objective time, or of any attempt to define being and time in terms of what is static and unchanging. Art is central for the ontology at stake here, and the ontology is one of art, because it is a matter of questioning the spatial-temporal being of the sensible, and not the being of the purely intelligible; and because art (as I try to show) is itself essentially concerned with revealing this ontological dimension of the sensible. Author Keywords: Aesthetics, Art, Being, Fragment, Image, Time
Pedagogy of Renaturalization
This three-part dissertation will consider both theoretical and practical implications that Baruch Spinoza's (1632-1677) immanent philosophical system holds for developing a contemporary “pedagogy of renaturalization.” One of the intents of this thesis is to draw out how “intellectual slut shaming” is a naturalized part of neoliberal subjectivity. In chapter one, we will make the case that the Cartesian and neoliberal subjects share several parallel structures, including mind-body dualism. We will look at how Spinoza’s work supplies us with a powerful critique and expansion of the Cartesian subject. The intent here is to explore how we might apply a similar critique to the neoliberal subject and construct a more joyful subject that resists guilt, shame, and self-hatred. In chapter two, we will explore how Spinoza’s method of affirmation can give us a process to engage ourselves in a pedagogy of renaturalizing ourselves; in other words, to engage in the radical self-reflexivity of understanding ourselves as a part of Spinoza's Nature in order to better affect becomings of ethical joy. We will also examine the challenges and criticism of the affirmative method, and how paradoxically these criticisms serve to reinforce intellectual slut shaming. Chapter three will explore the potential of the methodology of autoethnography and the development of what we are calling “auto-ethology” as a way to put such an affirmative method into practice. By reviewing the dissertation as a whole, we will show how it has been an engagement with Spinozist radical self-reflexivity all along and a performance of auto-ethology. Author Keywords: autoethnography, Baruch Spinoza, Cartesian dualism, critical pedagogy, intellectual slut shaming, neoliberal subject
Modeling drought derivatives in arid regions
We propose a stochastic weather model based on temperature, precipitation, humidity and wind speed for Qatar, as a representative arid region, in order to obtain simulated values for a drought index. As a drought index, the Reconnaissance Drought Index (RDI) is commonly accepted in agriculture and is used to measure drought severity. It can be used to price weather derivatives to help farmers reduce nancial losses from drought. RDI, which is the ratio of precipitation to evapotranspiration, is calculated by considering crop growth stages. The use of dierent crop coecient value depending on the growth stage to calculate evapotranspiration can provide improved values for RDI. Additionally, six calculation methods for evapotranspiration using weather data are investigated to obtain accurate values for RDI. Author Keywords: Evapotranspiration, Markov chains, Mean reversion processes, Reconnaissance Drought Index, Stochastic dierential equations, Stochastic weather models
Becoming Hybrid
Institutional military strategists are developing theories of asymmetric and unconventional warfare that complicate the notion of strategic agency, the idea that military action emanates from a coherent agential source or subjectivity. This thesis attempts to push the conceptual trajectories of the theories of Hybrid War, Unrestricted War and Onto-power towards an even more radical complication of the notion of strategy - towards an ecological understanding of war as an unwinnable, self-perpetuating process. Recent geopolitical events are meticulously examined, as are institutional doctrinal and theoretical frameworks that stop just short of imploding the conventional agential notion of strategy. Insights from the work of Gilles Deleuze and Felix Guattari, as well as Brian Massumi, particularly the concepts of multiplicity, assemblage, and ontopower, are employed in the thesis, which is itself a “heterogeneous assemblage” of elements ranging from Israeli war theory and Chinese military doctrine to etymology and post-structuralist philosophy. Author Keywords: Agency, Assemblage, Deleuze, Hybrid warfare, Multiplicity, Strategy
While the Lonely Mingle with Circumstance
Emmanuel Levinas’ philosophy focuses on the idea that no human subject exists outside of their relationship to other people. Each of us holds a profound degree of responsibility to and for all others. Since responsibility is fundamental to human (co)existence, it does not impede on freedom but proves that the sovereign individual is a dangerous myth: any philosophical, political or economic system which places us in antagonism is inherently violent and arguably fallacious. Many instances of injustice and violence can be attributed to advances in technological rationality and other forces of modern egoism with historical roots. By forwarding a somewhat politicized interpretation of Totality and Infinity and drawing on Jacques Derrida’s landmark reading of Levinas, this thesis explores the implications of Levinas’ thought for modern politics and the potential of Levinasian ethics as a remedy for both the alienation of the modern subject and the continued justification of oppression. Author Keywords: Ethics, Levinas, Other, Relation, Responsibility, Subjectivity
