Developing social skills: A pilot study of a parent-mediated intervention for children with ASD
Guidelines regarding social skills interventions for children with ASD suggest incorporating a holistic approach. This includes increasing the family's understanding of deficits associated with ASD, integrations of natural environments, and parents as active agents while supporting their well-being. The current availability of holistic parent-mediated interventions for children with ASD is limited, with no qualitative understanding of its potential benefits for either the parent or child. The current study examined qualitative parent reports on a parent-mediated social skills intervention for children with ASD (TalkAbilityTM) incorporating a longitudinal approach (i.e., 6-month follow-up). Following Braun and Clarke's model of thematic analysis, data was coded into four themes: 1) communication difficulties, frustrations and progress, 2) social relationships and concerns, 3) communication strategies, and 4) thoughts and emotions surrounding TalkAbilityTM. Results highlight the importance of considering parent experiences regarding interventions for their child's social communication skills through a qualitative viewpoint.

Assessing the Potential of Permaculture as an Adaptation Strategy Towards Climate Change in Central Ontario
This thesis uses three approaches to assess the potential of permaculture in Central Ontario. This was done using a vegetable field trial and modelling programs to determine the effectiveness of permaculture to decrease negative impacts of climate change based on projected climate values derived from regional circulation models. The first approach showed no statistical difference (P<0.05) of applying varied volumes and combinations of organic amendments on crop yields. The second approach indicated permaculture may be a sustainable production system with respect to soil erosion when compared to traditional agricultural practices. The third approach was inconclusive due to the lack of quantitative literature on permaculture management impacts on biomass yields, soil carbon or nutrient retention, which were missing from basic and scientific literature searches. The models used within this thesis include USLE, RUSLE2, AgriSuite, RothC and Holos.

Exploring Characteristics of those Utilizing Different Modalities of Treatment for Substance Use Disorders
Substance use disorder (SUD) is a pervasive psychological disorder detrimentally impacting both individuals and society on a psychological, economic, and social level. The best protocol for treating SUD as well as what defines success in treatment is often debated in the research. However, researchers agree that different psychosocial factors can influence outcomes. The literature suggests that mood, dark personality traits (narcissism and psychopathy), social supports, and state of change may be associated with treatment for SUD. The current study explored whether these factors predicted the type of treatment (abstinence-based or harm reduction) individuals with SUD were in. The sample consisted of 37 participants in a 12-step abstinence-based program and 65 in a harm reduction program at a local hospital. Results indicated that those in abstinence-based groups reported significantly fewer symptoms of anxiety and depression, lower levels of narcissism and psychopathy, more social supports, and advanced stage of change in comparison to those attending a harm reduction program. In addition, depression, narcissism, and perceived social support were significant predictors of treatment group membership. These findings suggest that those involved in abstinence-based groups appear to experience overall more wellness than those in harm reduction. Although further research is needed to specify the relations among factors, this study is a step towards understanding the difference between people who utilize one program versus another.

Biogeography of Carabidae (Coleoptera) in the Boreal forest
Basic biogeographic information is lacking for many species, such as where species are found, and how they dispersed there. Using ground beetles collected during 2008-2015 from across northern Ontario and Akimiski Island, Nunavut, I present new information on ground beetle distribution in this eastern Nearctic boreal forest, including 2 first Canadian records, 9 first provincial and 48 first territorial records, as well as 74 new records that extend the known range of many large and common ground beetles several hundred kilometres. I used these distributions to redress the knowledge gap that includes fundamental distribution data, i.e. the Wallacean shortfall, and to inform later chapters in my thesis.In Chapter 3, I examine the range expansion pattern of Carabus granulatus, a non-native species, as it spread across northeastern North America and I provide a new range record. Northern Ontario is already under threat from non-native species entering the region and it is important to conduct studies in the region before more disturbance associated with development occurs. In Chapter 4, I examine the hypothesis that northern Ontario effectively acts as a climate plateau for poikilotherms, using the predictions from Bergmann's rule as my metric. The body length of ground beetles does not appear to change over the small temperature gradient that exists across northern Ontario latitudes, supporting the climate plateau hypothesis. In Chapter 5, I test hypotheses about dispersal mechanisms that contributed to post glacial re-establishment of ground beetles using predictions of geographic distribution patterns as metrics. I found that ground beetles were likely carried downstream by rivers which aided their dispersal northward from southern refugia. I infer from the current geographic distributions that flightless ground beetle species are still expanding their range in this boreal region. Finally, I argue that there is an urgent need for more basic research on species distributions while it is still possible in regions like northern Ontario, before increased industrial and agricultural development, and expanding resource extraction projects obliterate evidence of historic ecological processes.

Effects of Opioids on the Development and Reproductive Capacity of Japanese Medaka, Oryzias latipes
Opioid drugs are among the microcontaminants that are discharged with domestic wastewater into the aquatic environment with the potential to affect the development and reproductive capacity of aquatic organisms. To study the effects of exposure of fish to opioid drugs, Japanese medaka (Oryzias latipes) were exposed over a full life cycle to environmentally relevant (i.e. ng/L) concentrations of two opioids, codeine and fentanyl. Acute exposure of early life stage (ELS) of medaka to codeine resulted in slightly extended times to hatch, but no increase in embryo mortalities or reduced hatching success. Chronic exposure to codeine at a nominal concentration of 25,000 ng/L over a full life cycle interfered with growth, reducing the weight of the fish at maturity. Life cycle treatments with codeine at all test concentrations resulted in a significant reduction in the number of eggs produced in reproductive trials, as well as a reduction in the numbers of mature oocytes in adult females. High treatments with codeine also increased the percentage of immature sperm cells in adult males. Life cycle exposures to codeine also resulted in reduced whole-body concentrations of several hypothalamic-pituitary-gonadal (HPG) axis hormones, including reduced levels of luteinizing hormone in male and female fish and a reduction in 11-ketotestosterone in males and 17β-estradiol in females. Fentanyl did not affect reproduction or HPG hormones at the exposure concentrations tested, but high fentanyl exposures increased the mortality rate among ELS's of the F1 generation offspring from life cycle exposed adults. The results of this thesis contribute to the literature on the environmental impacts of microcontaminants of wastewater origin and, the potential for effects in fish exposed to opioids.Keywords: Opioids, microcontaminants, fentanyl, codeine, sexual development, reproduction.

Mindful or Mind Full? Exploring the Associations Between Relationships, Mindfulness, and Stress
Past research has indicated a relationship between attachment and mindfulness; however, less is known about the behavioural outcomes of this relationship. The purpose of the present study was to test a new, more in-depth structural model of the relationship between attachment and mindfulness, and further explore the effects of attachment and mindfulness session type (group or individual) on attendance and willingness to continue mindfulness. As predicted, both the self and other model of attachment were positively associated with mindfulness. Surprisingly, individuals who were initially interested in the follow up sessions reported significantly more negative models of others than individuals who were not interested. For the in-person sessions, no significant differences were found for participant attendance or willingness to continue based on attachment and/or type of session. The discussion of results highlights the importance of people's view of others for developing mindfulness traits and developing strong client-provider relationships in therapeutic and intervention settings.

Olives in the Mountains: A Case Study of the Roman city of Sagalassos
Olives have been grown in the Mediterranean region for millennia and have been a staple crop in many of its cultures. This was never more true than during the Hellenistic (323 – 133 BC) and Roman (133 BC – AD 450) periods in the Mediterranean. This thesis examines the territory of the Roman city of Sagalassos in the region of Pisidia, modern province of Burdur, and determines if olives could have been cultivated in the territory. While there have been studies that state olives were cultivated in the territory during the Hellenistic and Roman periods, modern farmers as well as agronomic manuals state that such growth is not possible. This thesis present data that indicates that olives were grown in the territory of Sagalassos, but also examines the conditions olives require to grow and if such conditions existed in Pisidia. Through this I will be able to conclude whether the past presentation of data has does indeed prove that olives were grown within the territory of Sagalassos.

Hibernian Imagination: A Study of Ireland's Violent Cultural Imaginary through Writing, Music, and Film
Artistic expressions such as writing, theatrical productions, music, and film arguably contribute to a culture's representation of itself to the outside world. Most cultures have been either read or misread through their artistic outputs over the course of history, although the Irish culture stands as a particularly misunderstood one. Through years of colonization and rebel warfare, the country's culture has acquired a particularly imagined depiction; violent, which through centuries has resulted in a flawed cultural imaginary today. This thesis presents this issue and proposes a means to better understand the Irish culture through a deeper understanding of the factors that have led the country's cultural imaginary to its current misrepresentative state. Through an exploration of texts, theatre, music, and film, this thesis uncovers the factors which have led to Ireland's current cultural depiction in hopes of creating a better understanding of the Irish culture.

"The Darkest Tapestry": Indian Residential School Memorialization at the Keeping Place at Fort Qu'Appelle, Saskatchewan.
This doctoral research project is a part of the quest for an inclusive telling of Canada's national identity and will focus on the creation of a memorialization Keeping Place model to commemorate the Indian Residential School system in Canada. My dissertation is interdisciplinary and contributes to the fields of cultural history, memory and post-colonial studies. In response to the TRC recommendation that calls on all Canadians to "develop and implement a national heritage plan and strategy for commemorating residential school sites, the history and legacy of residential schools, and the contributions of Indigenous peoples to Canada's history", this project aims to contribute a unique analysis and discourse to the existing literature as it will focus on developing a process of commemoration of the IRS system by uniting the architectural/geographical location not only as a place/space of colonizing "perpetrator architecture" but also as a Keeping Place and "site of memory/lieu de memoire" or conscience. This project will also engage the concepts of "Indigenous Métissage" and "Cultural Interface" to aid in the creation of an educational commemoration and reconciliation Keeping Place model for all Canadians.

Monitoring and fate of selected tire-derived organic contaminants
Road runoff is a vector for the transport of potentially toxic chemicals into receiving waters. In this study, selected tire-derived chemicals were monitored in surface waters of rivers adjacent to two high traffic highways in the Greater Toronto Area in Ontario, Canada. Composite samples were collected from the Don River and Highland Creek in the GTA during 5 hydrological events that occurred in the period between early October 2019 and late March 2020, as well as an event in August 2020. Grab samples were collected from these rivers during a period of low flow in August 2020, as well as during a storm event in July of 2020. Analysis was performed using ultra-high pressure liquid chromatography with high resolution mass spectrometric detection (UHPLC-HRMS). Hexamethoxymethylmelamine (HMMM), a cross-linker of tire material, was detected at elevated concentrations (> 1 µg/L) during rain events in the fall and winter of 2019-20 and during a period of rapid snow melt in early March of 2020. These samples were also analyzed for the tire additive, 6PPD, and its oxidation by-product, 6PPD-quinone, as well as 1,3-diphenylguanidine (DPG). In many samples collected from the Don River and Highland Creek during storm events, the estimated concentrations of 6PPD-quinone exceeded the reported LC50 of 0.8 µg/L for Coho salmon exposed to this compound. Temporal samples collected at 3-hour intervals throughout rain event the October 2020 showed that there was a delay of several hours after the start of the event before these compounds reached their peak concentrations. In addition, 26 candidate transformation products and precursor compounds of HMMM were monitored; 15 of these compounds were detected in surface waters in the GTA. The maximum total concentration of this class of methoxymethylmelamine compounds in surface water samples was estimated to be 18 µg/L. There is limited knowledge about the properties of HMMM, its precursor contaminants, and its transformation compounds, as well as their fate in the environment. COSMO-RS solvation theory was used to estimate the physico-chemical properties of HMMM and its derivatives. Using the estimated values for these properties (e.g., solubility, vapour pressure, log Kow) as inputs to the Equilibrium Criterion (EQC) fugacity-based multimedia model, the compounds were predicted to readily partition into aqueous media, with mobility in water increasing with the extent of loss of methoxymethyl groups from HMMM. Overall, this study contributes to the growing literature indicating that potentially toxic tire-wear compounds are transported via road runoff into urban surface waters. In addition, this study provides insight into the environmental behaviour of HMMM and its transformation products.
