The generation of polymer brushes by surface-initiated polymerization techniques has become a powerful tool for the creation of hybrid materials. Governed by the type and amount of polymer used in the modification, the chemical and physical properties of a surface can be tailored by polymer grafting. In this study, a commonly used polymer flocculant, polyacrylamide (PAM), was grafted onto the surface of activated carbon (AC). This hybrid material was designed with the intent of combining the functionalities of both the activated carbon and the polymer flocculant, potentially acting in a synergistic manner. The PAM grafted AC (AC-PAM) was examined as a flocculant in the treatment of mature fine tailings (MFT). AC-PAM was synthesized by surface-initiated activators generated by electron transfer atom transfer radical polymerization (SI-AGET ATRP). This was accomplished by pre-functionalizing the surface of activated carbon by oxidation, followed by the attachment of an ATRP initiator. From this surface, SI-AGET ATRP of acrylamide monomers was performed. The resulting AC-PAM was characterized by FTIR, XPS, TGA, SEC, and BET analysis. Characterization results indicated the successful grafting of polyacrylamide from the surface of activated carbon. The AC-PAM was measured to contain approximately 10.6% PAM by weight, and the average-number molecular weight of the grafted polymer was 176,100 g/mol. The flocculation performance of AC-PAM and PAM were compared by performing settling tests with 5 wt% MFT. The optimal polymer dosage for PAM was found to be 10,000 ppm, producing an initial settling rate of 3.51 m/hr and a supernatant turbidity of 430 NTU. Comparatively, the optimal dosage for AC-PAM was found to be 20,000 ppm, producing a supernatant turbidity of 114 NTU and a fast initial settling rate of 27.54 m/hr. The improved flocculation performance is hypothesized to occur due to the effective increase in the molecular weight of PAM when grafted from the surface of activated carbon. In all, our work demonstrates the successful grafting of PAM from AC, as well as potential wastewater treatment applications for these types of hybrid materials.

Understanding snowpack variability is important as it plays an imperative role in environmental, hydrologic, and atmospheric systems. Research questions related to three linked areas were investigated in this thesis: 1) scaling issues in snow hydrology, 2) forest-snowpack relationships, and 3) methods of integrating snow water equivalent (SWE) into a hydrologic model for a large, forested drainage basin in central Ontario. The first study evaluated differences in SWE across process, measurement, and model scales. Point scale snowpack measurements could be bias corrected using scaling factors derived from a limited number of transect measurements and appropriately stratified point scale measurements may be suitable for replacing transect scale mean SWE when transect data are not possible to collect. Comparison of modelled products to measurements highlighted the importance of understanding the spatial representativeness of in-situ measurements and the processes those measurements represent when validating snow products or assimilating data into models.The second study investigated the efficacy of field-based, and remotely sensed datasets to describe forest structure and resolve forest-snowpack relationships. Canopy cover was highly correlated with melt rate and timing at the site scale however, significant correlations were present in 2016 but not 2017, which was attributed to interannual differences in climate. Peak SWE metrics did not correlate well with forest metrics. This was likely due to mid-winter melt events throughout both study years, where a mix of accumulation and melt processes confounded forest-snowpack relationships. The third study evaluated the accuracy of the Copernicus SWE product and assessed the impact of calibrating and assimilating SWE data on model performance. The bias corrected Copernicus product agreed with measured data and provided a good estimate of mean basin SWE. Calibration of a hydrologic model to subbasin SWE substantially improved modelled SWE performance. Modelled SWE skill was not improved by assimilating SWE into the calibrated model. All models evaluated had similar streamflow performance, indicating streamflow in the study basin can be accurately estimated using a model with a poor representation of SWE. The findings from this work improved knowledge and understanding of snow processes in the hydrologically significant Great Lakes-St Lawrence Forest region of central Ontario.

Cytokinins (CKs) are a pervasive group of growth-promoting signaling molecules spanning every kingdom of life. Their roles are best known in plants, where they act as phytohormones controlling nearly all aspects of plant growth and development. CKs continue to be detected in new organisms, posing questions about their roles in such widespread forms of life. The research presented in this thesis, therefore, investigated CK dynamics in a non-plant system using the simple eukaryotic model, Dictyostelium discoideum. Prior to this thesis, CKs were established as key intercellular signals necessary for proper development of D. discoideum – specifically in the induction of sporulation and maintenance of spore dormancy. However, there were no documented roles of CKs prior to the late stages of multicellular development. Comprehensive mass spectrometric screening for CKs detected six novel CK forms during all stages of D. discoideum growth and development. Based on these findings, a model was proposed that mapped CK biosynthesis in D. discoideum. The CK profiles indicate that there are differing dominant CK forms during vegetative growth and early development compared to those detected during late multicellular development. This led to the hypothesis that CKs have different roles during the distinctive life cycle stages of D. discoideum. This hypothesis was tested by generating knockout and overexpression strains of the key, primary CK biosynthesis gene, iptA, to investigate potential expanded roles for CKs during growth and the early stages of D. discoideum development. iptA-deficiency resulted in cytokinesis defects and both iptA-deficiency and overexpression caused altered mitochondrial morphology, dysregulated TCA cycle and amino acid metabolism, as well as increased levels of the energy metabolite, AMP. These combined phenotypes were suggestive of mitochondrial-associated dysfunction in vegetative growth and provided the first evidence of expanded roles of CKs during the D. discoideum life cycle. This was the first metabolomics-based evidence of CKs influencing mitochondrial function in D. discoideum. Lastly, a key CK-activating enzyme was functionally characterized, DdLOG, and additional CK biosynthesis enzymes were identified for future examination. Together, the findings of this thesis provide insights into: CK biosynthesis in a non-plant associated model; new roles for CKs during the D. discoideum life cycle; and CK interactions with mitochondria. The methods established as part of this thesis can be used as a foundation for characterizing further CK biosynthesis enzymes and as a guide for detecting subtle sub-cellular phenotypes related to CK metabolism in D. discoideum and other CK-producing organisms.

This research aimed to capture the experiences of cities that have endeavored to localize the SDGs in their areas. Literature review and one-on-one interviews with SDG practitioners have been conducted to glean best practices and effective strategies to develop recommendations for how cities in Canada should plan to localize the SDGs in their areas. The research uncovered themes in relation to building on existing initiatives, stakeholder management, data management, and the role of personal rapport and connections in professional settings. This research also revealed an important tension between the top-down approach of adopting a unified federally devised framework and a bottom-up community indicator approach. Finally, the research uncovered opportunities to increase support for local organizations and city governments embarking on localizing the SDGs through engagement with academia and partnering with faculty and graduate students at the local university to incorporate graduate research into SDG localization efforts and tap into funding opportunities. The research also resulted in a flow chart that is gleaned from interviews and the literature review to describe a step-by-step process that cities and communities could deploy to localize SDG targets and indicators.

The Multidimensional Inventory of Personal Intelligence (MIPI) was designed to measure three related dimensions of the personal intelligence (PI) construct: emotional intelligence (EI), social intelligence (SI), and motivational intelligence (MI). The MIPI has psychometric properties and a theoretical structure that improves on the shortcomings of existing trait EI measures. The aim of the first study was to create and validate a shortened form (MIPI- Short) that maintains the same factorial structure of the original MIPI. The purpose of the second study was to validate the new scale with measures of conceptually similar constructs (e.g., emotional intelligence, Alexithymia) with various measurement methodologies (self-report, observer-report, and performance-based). Results from Study 1 found that the MIPI-Short had good factorial structure in two independent samples, as well as adequate internal reliability, and good incremental validity. The results of Study 2 demonstrated that the MIPI-Short had good construct validity as it generally related as expected with measures of EI and Alexithymia. The findings of both studies provide evidence for the validity of the MIPI-Short as a brief measure of Personal Intelligence. Directions for further research are emphasized, as the validation process is on-going for any assessment tool.

This thesis critically engages with the historic site Sainte-Marie among the Hurons. The most visited historic site in Ontario anchors a vivid and pervasive story of early Canada while archaeological excavations and reconstruction have a history of their own. It is intertwined with the Martyrs' Shrine and regional sites of significance and pilgrimage in the Catholic world where veneration as saints of Jesuits collectively known as the Canadian Martyrs takes place. Through a panoramic perspective and participant-observer experiences within the sites, in present-day Wendake, Québec, and at a Jesuit mission in Chiapas, Mexico, dimensions of landscape, temporality, materiality, and identity are explored. Development of this history and place in relationship to Indigenous peoples, the Catholic Church, and the Canadian public are examined with consideration for findings of the Truth and Reconciliation Commission, advancement in archaeological knowledge, and ongoing tensions in the practice of archaeology in Ontario.

Contemporary struggles with Indigenous identities in Canada are deeply rooted in the historical and ongoing impacts of colonization, which have left profound and lasting effects on different geographical regions across the country. These struggles are multifaceted, encompassing complex questions surrounding who qualifies as Indigenous and what criteria are used to authenticate claims of Indigenous heritage.

In the modern era, the digital landscape has become an integral part of our daily lives, revolutionizing how we interact with the world around us. Digital spaces, including the vast expanse of the Internet, various social media platforms, and mobile applications, have transformed how we communicate, conduct business, seek entertainment, and share information. These virtual environments offer unparalleled opportunities for connectivity, collaboration, and the exchange of resources and ideas.Within this digital realm, social media platforms have emerged as powerful tools for self-expression and exploration of identity. Individuals increasingly use these platforms to delve into the complexities of their identities, including their intersectionality and connections to specific geographic locations. Research has shown that this exploration often leads to a reclamation and revitalization of Indigenous identities, serving as a form of political resistance against the ongoing legacies of colonization. Through social media, Indigenous individuals and communities are able to reclaim their voices, assert their autonomy, and challenge dominant narratives.

This research delves into how digital spaces, mainly the social media platform of TikTok, shape Indigenous identity formation, maintenance, and resurgence. By employing a mixed-methods approach, this study analyzes various dimensions of this phenomenon, including the role of storytelling, community building, and cultural expression in digital spaces. Moreover, the research explores how these digital platforms can empower Indigenous communities to reclaim, revitalize, and reconstruct their identities and notions of community. Ultimately, by examining the impact of digital spaces on Indigenous identity, this research provides valuable insights into contemporary practices of identity revitalization and proposes strategies to support Indigenous futures in a rapidly evolving digital landscape.

This research used the Medicine Wheel, adapted from the research of Dr. Kathleen E. Absolon, Anishinaabekwe from Flying Post First Nation, in her article Indigenous Wholistic Theory: A Knowledge Set for Practice, as a framework to explore the dynamic interplay between Indigenous identity and the digital age. It highlights how each quadrant—East (birth and rejuvenation), South (relationships and advocacy), West (challenges and resilience), and North (wisdom and healing)—provides unique insights into the cultural preservation, self-discovery, community engagement, and integration of traditional knowledge with modern technology. Indigenous communities leverage digital platforms to rejuvenate cultural practices, foster relationships, advocate for social justice, and empower their voices while navigating the complexities of online spaces and ensuring cultural authenticity.

The findings emphasize the transformative potential of social media in preserving and revitalizing Indigenous cultures, advocating for critical issues, and empowering different generations. Ethical engagement in digital spaces is crucial, as well as promoting cultural respect and addressing historical injustices. The research underscores the importance of balancing traditional values with modern technology to foster resilience, empowerment, and holistic well-being within Indigenous communities.

The widespread adoption of electric vehicles (EVs) is crucial for reducing transportation-related emissions and achieving sustainability goals. However, a significant research gap exists regarding specific consumer groups, such as university students, and their attitudes toward EV adoption, as they represent a demographic influential in shaping future adoption patterns. This research uses a quantitative approach to explore Trent University students' attitudes and perceptions toward EV adoption.A survey of 154 students examined the factors influencing their willingness to adopt EVs. Various quantitative data analyses, including cross-tabulation tables and chi-square tests, were employed to investigate the relationships between socio-demographic, social, environmental, and economic factors and students' willingness to adopt EVs. The findings indicate that while socio-demographic factors do not significantly influence willingness to adopt EVs, factors such as first-hand experience, knowledge about EVs, social influence, upfront costs, charging infrastructure, and government incentives significantly impact students' willingness to adopt EVs. The study revealed that although students recognize the benefits of electric vehicles (EVs), such as reduced emissions, lower operating costs, enhanced energy efficiency and health advantages, key barriers to student EV adoption include high upfront costs, limited charging infrastructure, concerns about driving range and charging time, and a need for more knowledge and awareness. The findings of this study fill a significant research gap and add to the existing literature on EV adoption. The insights generated can inform targeted strategies by policymakers, educational institutions, and EV manufacturers to promote widespread EV adoption among students.

Many communities in Canada rely on water sourced from boreal forest headwaters for their drinking water. The Boreal Shield Ecozone is highly susceptible to climate change which threatens to exacerbate the effects of natural and human-driven disturbances such as wildfire, insect infestation and harvesting on water quality. Therefore, examining source water quality in headwater catchments within the Boreal Shield Ecozone is crucial to elucidating the potential implications of these disturbances to water treatment processes in the context of a changing climate. A synoptic water sampling investigation was conducted to evaluate how dissolved organic carbon (DOC) quantity and quality and disinfection by-product formation-potential (DBP-FP) quantity varied across space and time in the Algoma region of central Ontario. Over a five-month timeframe (June 2021 - October 2021), 168 streamflow estimates and 176 water samples were collected across 30 catchments (catchment areas from 0.2 - 106.8 km2) which varied in their forest disturbance histories. DOC concentration ([DOC]) ranged from 2.4 - 38.2 mg L-1 and tended to be higher in harvest-dominated sites, while no discernible differences in SUVA254 were observed between catchment types. DOC export estimates ranged from 1.0 - 63.2 g C m-2 over a 141-day period (June 5th - Oct. 23nd, 2021). Fluorescence indices for quantifying DOC composition suggested that all catchments were dominated by humified and terrestrially sourced carbon. DBP-FP values were positively correlated to UV-254 (r = 0.76 - 0.78) and [DOC] (r = 0.85 - 0.88), such that DBP-FP spatiotemporal patterns were strongly coupled to DOC dynamics. Multiple linear regression analysis identified that open water was negatively related to [DOC] and SUVA254 and explained the most variability in their spatiotemporal patterns. In addition, catchment area, which was negatively related to [DOC] and SUVA254, and legacy insect infestation and harvesting disturbance helped improve model explanatory power. Other predictor variables, such as slope, wetland cover, coniferous forest cover and recent forest disturbance (i.e., 5-year harvesting and 5-year insect infestation), showed relatively poor explanatory power. Variability in DOC export estimates may be explained by harvesting disturbance (adjusted r2 = 0.68 - 0.82). The results of this study emphasise that complex processes across the terrestrial-aquatic continuum, which are influenced by several factors, such as runoff, forest disturbance and landscape heterogeneity, govern the spatiotemporal patterns in water quality across boreal headwaters within the Algoma region.

This thesis focuses on the Atoskiwin Training and Employment Centre of Excellence (ATEC) in NelsonHouse, Manitoba, and its contribution to Aboriginal adult education and the economic development of the Nisichawayasihk Cree Nation (NCN). The study examines ATEC within the larger history of NCN's relationship with its land, hydroelectric development in northern Manitoba, and Wahbung: Our Tomorrows, the 1971 alternative blueprint to the federal White Paper. I argue that ATEC has played a key role in nurturing a resurgence of the social and economic capacity of people in Nelson House.

The research approach used in this study is ethnographic, drawing on the researcher's livedexperiences and relationships with the community and ATEC. Supporting qualitative data were collected through interviews with ATEC staff and students, allowing for an in-depth exploration of their experiences, perspectives, and the impact of ATEC on their lives and employment opportunities. The thesis examines the historical context of ATEC. It also explores the challenges and achievements of ATEC during two distinct phases: the initial phase focused on training for skilled and unskilled labourers during the construction of the Wuskwatim hydroelectric dam, and the subsequent phase after the dam's completion.

The research shows how ATEC has contributed to the economic and social capacity of NelsonHouse, analyzing its impact on community development and employment opportunities. It also points out the need for greater control, infrastructure and resources for Aboriginal adult education in rural and northern areas. The thesis concludes by discussing the findings and suggesting potential areas for improvement and growth in ATEC's programming and delivery methods.
