My Canadian Story
Canada prides itself on being a multicultural nation, but the stories of people who are not “Canadian-Canadians,” as defined by Eva Mackey, are underrepresented in archives. This project investigates three local archives and one online archive in Peterborough, Ontario, employing Rita Dhamoon’s practice of “accounts of meaning-making” to understand how archives contribute to a community’s understanding of itself and who belongs there. The findings indicate that the city’s “Canadian-Canadians,” who have portrayed them as transient and only temporarily settled in the city, frequently mediate the stories of “other” populations in Peterborough’s archival records. This account of meaning-making provides an entry point for changing this understanding and making archives more welcoming and accessible in the city and beyond.

Visions of the Sedantary “I”/eye
This thesis explores the seemingly innocuous call to “grow up,” which is never simply a biological imperative. It is also a moral one. Demanding that one should “grow up” is not demanding that one grow older, but that one transform into a specific kind of subject – the “grown up.” In the reading advanced here, The Little Prince thermalizes the suppleness of the figure of the grown up through a series of fantastic encounters. In particular, perception and corporeality will be taken up as the two interlocking ways we are often pushed towards an understanding of adulthood that is coextensive with an Enlightenment conception of subjectivity. Perception, having emerged from a sedimented economy of looking, produces norms and practices of attentiveness where much of our perceptual field is consigned to infrastructural obliviousness. This intensification of attention, in turn, coincides with a broader project of corporeal discipline that began with the body’s sedation through the chair. The chair is itself an element of the disciplinary machine that regulates attention, where the pedagogical injunction to “pay attention” is often accompanied by the postural injunction to “settle down” and “sit up straight.” The chair, then, not only individuates and renders those individuated bodies docile, but also readies them for an entry into the world of grown-ups. Author Keywords: Attention, Enlightenment, Maturation, Saint-Exupery, Sedantariness, Subjectivation
Ground-truthing effective population size estimators using long-term population data from inland salmonid populations
Effective population size (Ne) is a foundational concept in conservation biology, in part due to its relationship to the adaptive potential of populations. Although Ne is often estimated for wild populations, it is rarely calibrated against actual population estimates (Nc) other than to produce Ne/Nc ratios. This project used demographic and genetic data for from two intensively-studied populations of lake trout (Salvelinus namaycush) in Ontario’s Experimental Lake Area (ELA) as baseline data for evaluating the performance of multiple Ne estimators. Several temporal and single-time (point) genetic methods of estimating Ne were compared against demographic Ne estimates and known population data, as well as variation and consistency within and among Ne estimators. Changes in genetic Ne estimates over time were also compared to changes in demographic structure and fluctuating census estimates, including the effect of an experimentally manipulated population bottleneck on demographic and genetic Ne estimates during population reduction and recovery. Sampling years that included the most pre-, during and post-bottleneck data revealed the lowest estimates using temporal estimators (Ne = 16 to 18) despite pre- and post-bottleneck census estimates of 591 and 565. Estimation of Ne had increasingly tighter confidence intervals as sample sizes approached the actual number of breeding individuals in each population. Performance differences among the tested estimators highlight their potential biases and reliance on different assumptions, illustrating their potential value and caveats for assessing adaptive potential of wild populations.

How to Forge an Empire
The goal of this thesis is to explore the production of ferrous (iron) armaments in the Middle Byzantine Empire, and more specifically the tenth century. Three cornerstones define the current research: (1) An exploration of the technology at use in the production of ferrous armaments. (2) A comprehensive look at the logistical and organizational structures which facilitated this industry. (3) A closer look at the labour investments required to manufacture armaments through an ethnographic and experimental approach. The tenth century document known as the De Cerimoniis forms a foundational pillar of the current study. The document details the quantity and types of military equipment required for a naval expedition launched by the Byzantines in A.D. 949. The information provided within has made this inquiry into logistics possible, and has allowed for the assessment of overall trends in the tenth century arms production industry. Author Keywords: armour, arms production, Byzantine military, logistics, metallurgy, weapons
Stoichiometric food quality affects responses of Daphnia to predator-derived chemical cues
While both resource quality and predator-derived chemical cues can each have profound effects on zooplankton populations and their function in ecosystems, the strength and nature of their interactive effects remain unclear. We conducted laboratory experiments to evaluate how stoichiometric food quality (i.e., algal carbon (C):phosphorus (P) ratios) affects responses of the water flea, Daphnia pulicaria, to predator-derived chemical cues. We compared growth rates, body elemental content, metabolic rates, life history shifts, and survival of differentially P-nourished Daphnia in the presence and absence of chemical cues derived from fish predators. We found effects of predator cues and/or stoichiometric food quality on all measured traits of Daphnia. Exposure to fish cues led to reduced growth and increased metabolic rates, but had little effect on the elemental content of Daphnia. Elevated algal C:P ratios reduced growth and body %P, increased respiration, and increased body %C. Most of the effects of predator cues and algal C:P ratios of Daphnia were non-interactive. In contrast, the declines in daphnid survival and related population growth rates that arose because of poor food quality were amplified in the presence of predator-derived cues. Our results demonstrate that stoichiometric food quality interacts with anti-predator responses of Daphnia, but these effects are trait-dependent and appear connected to animal life-history evolution. Author Keywords: Daphnia, ecological stoichiometry, indirect predator effects, life history, phosphorus, predator-prey relationships
'This is where the poetry comes out'
Since 1984, poetry slams have emerged as a politicized expressive movement of performing the personal and political through poetry competitions. Slams are also discursively spatialized, often represented as “spaces” that are “safe,” “inclusive,” etc. In this thesis, I investigate how, why, and to what effect the Peterborough Poetry Slam produces, consolidates, and challenges such “resistant spaces.” Drawing on interviews and participant observation, I consider how the slam’s reiterative practices facilitate its space-making by encouraging performances that resist, reimagine, and sometimes inadvertently reify dominant societal norms. I argue that this space-making is imperfect yet productive: though not resistant space in any straightforward or static way, the slam continuously produces possibilities to challenge norms and confront power. This thesis contributes to scholarship on performative space and creative resistance movements. In an era when political resistance to power structures is often silenced, this research offers insights of potential significance to other resistant space-makings.

Branding of the Prime Minister
From 1949-1957, Prime Minister Louis St. Laurent was the face of the Liberal Party. Party branding was wholly devoted to his friendly, ‘Uncle Louis’ brand image. St. Laurent’s image was manipulated and manufactured without public preconception, establishing the modern tactics of personal branding still used by his successors. This thesis studies the elections of 1949, 1953, and 1957, analysing photos, advertisements, speeches, archival documents, memoirs, newspapers, and other sources to show the development of Liberal branding strategy. It employs political scientist Margaret Scammell’s conceptualization of brand theory, showing how marketers used emotional brand differentiators and rational substantive performance indicators to sell ‘Uncle Louis’ to Canadians. The Liberals used St. Laurent and branding tactics to win two massive majorities in 1949 and 1953, and the Diefenbaker Tories used those same tactics to defeat them in 1957. ‘Uncle Louis’ proved the effectiveness of personal branding and leader-centered campaigns in Canadian politics.

Are We All on the Spectrum? Assessing Autistic Traits in the HEXACO Personality Framework
Autistic traits are characterized by difficulties with socialization, preference for order, and rigid and repetitive behaviour patterns. This study evaluated the psychometric properties of two measures of autistic traits, the Autism-Spectrum Quotient (AQ) and the Sub-threshold Autistic Trait Questionnaire (SATQ), and their associations with the HEXACO personality framework. The relationships between self-objectification, Need for Cognition (NFC), and autistic traits were also examined. In a student sample (N = 294), autistic traits were found to be negatively related to eXtraversion, but unrelated to self-objectification and NFC. However, individual subscales of the SATQ and AQ revealed different personality profiles, suggesting a non-unitary composition of the autistic trait measures. The AQ’s subscales failed to be represented in its factor structure. Intercorrelations between SATQ and AQ subscales showed that some subscales were uncorrelated with others. These concerns challenge whether autistic traits should be considered as a downwards extrapolation of Autism Spectrum Disorder.

Island Syndrome and Stress Physiology of Mice in the Genus Peromyscus
Biological differences between island and mainland conspecifics have been well studied, but few studies have addressed differences in stress physiology. Stressors, such as predation and competition for resources, cause the release of glucocorticoids (GCs). Characteristics of island wildlife, called “island syndrome”, are attributed to low levels of predators and competitors. I tested the hypothesis that island syndrome includes differences in GC levels between island and mainland rodents using two approaches; first, using white-footed mice (Peromyscus leucopus) from a near-shore archipelago (Thousand Islands, Ontario) and the nearby mainland; second, using study-skins of deer mice (Peromyscus maniculatus) from two archipelagos offshore of Vancouver Island, British Columbia. White-footed mice in the near-shore archipelago did not show characteristics of island syndrome, or changes in GC levels (feces and hair); however deer mice from both archipelagos in British Columbia were heavier and had lower hair GCs for their size than Vancouver Island mice.

Jail Time
Children of incarcerated parents are an understudied at-risk population. However, this thesis was designed to advance our understanding of the effects of parental incarceration and factors that may influence the impact. Using quantitative methods, possible moderating roles of gender, number of incarcerated parents, and contact frequency on the associations between attachment representations and problem behaviours were investigated in two samples. Results revealed that the number of incarcerated parents and contact frequency with incarcerated parents moderated the associations between attachment and externalizing behaviours. Furthermore, after controlling for several factors (e.g., gender, number of incarcerated parents, and contact) higher scores on secure parental attachment representations were consistently negatively associated with internalizing symptoms and externalizing behaviours. The discussion of findings highlight the utility of attachment theory in conceptualizing the impact of parental incarceration and the importance of fostering attachment security to promote positive mental health and behavioural outcomes for children of incarcerated parents. Author Keywords: attachment, internalizing symptoms, parental incarceration, problem behaviours
Fate and Effects of Silver Nanoparticle Addition in a Lake Ecosystem
The potential release of nanoparticles into aquatic environments is raising global concerns. As antimicrobials, silver nanoparticles (AgNPs) are among the most prominent form in use. Despite this, their fate, long-term toxicity, and ecological relevance have yet to be investigated largely under natural settings with seasonality and environmental complexity. To better understand the environmental significance, we released AgNPs into Lake 222 at the Experimental Lakes Area over two years. AgNPs remained suspended in the water column and were detected throughout the lake and in the lower food web. Total Ag concentrations ranged from below 0.07 to 18.9 μg L-1 in lake water, and were highly dynamic seasonally both in the epilimnion and hypolimnion depending on the physical, chemical and biological conditions of the lake. Approximately 60% of the measured Ag mass in October was present in the sediment in 2014 and 50% in 2015 demonstrating relatively high sedimentation and removal from the water column. During winter months, Ag was largely absent in the water column under the ice. After ice melt and before summer stratification, Ag concentrations increased in the lake suggesting AgNPs may not be tightly bound to the sediment and are able re-enter the water column during spring mixing events. Despite temporal variation, total Ag was highly synchronous across spatial locations for both years, indicating rapid dispersal upon lake entry. When investigating AgNP sizes using spICPMS, size distributions were similar across spatial locations, with the 40-60 nm size class constituting approximately 60% of all particles identified. Large aggregates (>100 nm) and dissolved Ag were infrequently detected within the lake. Ag accumulated in the lower food web ranging from 0.27-16.82 μg Ag mg C-1 in the bacterioplankton and 0.17-6.45 μg Ag mg C-1 in algae (particulate fraction). Partial least squares models revealed the highest predictors of Ag accumulation were dissolved nutrients including DOC, TDN, TDP in bacterioplankton. Major predictors for particulate Ag included temperature, dissolved oxygen, and sampling date. The diversity of predictors among biological compartments emphasizes the importance of understanding the role of environmental complexity within the lower food web. Despite Ag accumulation we did not detect strong negative effects on the lake food web. An increase in particulate and bacterioplankton chlorophyll-a occurred after addition in contrast to reference lakes, which may indicate a hormetic response to low dose AgNP concentrations. Our findings provide the first whole-lake perspective regarding Ag fate and toxicity, suggesting small scale experiments may overestimate environmental responses.

Elders And Indigenous Healing in The Correctional Service Of Canada
In our communities, we are continually challenged to reflect on effective responses to the people and events that put us at risk. This study is an examination of two distinctly different world-view responses: the colonial, dominant culture and the Indigenous world-view. The retributive understanding of the dominant culture applies assumptions about the nature of the world that are vested in colonial, paternal, and punitive processes aimed to extract compliance as a means of deterrence. Conversely, the consensual precepts of Indigenous world-view are rooted in community-based practices that require a process of collaboration and cooperation to create integrated relationships that glean responsibility. This study brings light to bear on the ongoing relational dissonance that exists between the following: the disproportionate representation of men and women of Aboriginal descent held under federal warrant in Canada; the legislated mandate contained within the Canadian Corrections and Conditional Release Act that places successful community reintegration as a primary objective for the Correctional Service of Canada (CSC); and the role, place, and function of Elders who work in CSC reception centres, healing programs, and Pathways Initiatives. This study explores the variables, assumptions, and differing world-views that contribute to the disproportionate representation of incarcerated adults of Aboriginal descent and the challenges that impede successful community reintegration. In order to effectively examine and make sense of the relational dissonance that exists between correctional theory and institutional practice, the research is driven by a central question: What is the role, place, and function of Elders in the delivery of Indigenous healing programs within Canadian federal prisons? The outcome of this work reveals practices of decolonizing justice and healing that can move assumptions and challenge paternal understanding. It is an approach that has the capacity to peel away relational dissonance, thus allowing space for public policy that sustains consensual understandings of community. Key Words: Indigenous, settler colonial, dominant culture, retributive justice, restorative justice, indigenous justice, Elder, healing, healing program, disproportionate representation, successful community reintegration, relational dissonance. Author Keywords: Elder, healing program, indigenous justice, relational dissonance, retributive justice, successful community reintegration
