Video games have always been intrinsically linked with the technology available for the progress of the medium. With improvements in technology correlating directly to improvements in video games, this has recently not been the case. One recent technology video games have not fully leveraged is Cloud technology. This Thesis investigates a potential solution for video games to leverage Cloud technology. The methodology compares the relative performance of a Local, Cloud and a proposed Hybrid Model of video games. We find when comparing the results of the relative performance of the Local, Cloud and Hybrid Models that there is potential in a Hybrid technology for increased performance in Cloud gaming as well as increasing stability in overall game play.

An interesting question arises upon viewing the 1939 film, The Wizard of Oz (MGM). The main character Dorothy Gale faces a long arduous journey on foot. Why did she not have a car? Women had formed strong associations with the automobile in its early years, yet they appeared to have weaker associations with the automobile a few decades later. A look back to three other "Dorothies" from the World War I era demonstrates the evolution of women's associations with the early automobile, and how war impacted them. In the pre-World War I years, women drivers appeared in film, while Dorothy Levitt wrote columns for other women on how to drive and repair a car and many other women invented safety technologies for automobiles. During World War I, the pinnacle of recognition for women's driving emerged with the woman ambulance drivers on the front lines. Dorothie Feilding was one of the first women to arrive in Belgium to drive ambulances, often while under fire. Feilding and many women like her were given war medals for their service, and their bravery was touted in newspapers. However, once the war ended, their accomplishments would be erased and ignored. In the post-World War I years, Dorothée Pullinger's experience as CEO of the Galloway factory illustrate how ideas of masculinity and femininity. promoted by governments after the war, impacted women. The Galloway factory in Tongland Scotland, was staffed by women engineers and workers. After World War I ended, these women were pushed out of their jobs. War-induced disability and its economic costs to governments were at the heart of gender inequities and served to displace women from automobile technology. Policies such as Britain's "Restoration of Pre-War Practices Act" set the stage for a script that constructed women's jobs as expendable and marketed ideas of the disabled soldier needing to "re-gain his manliness" by re-entering the labour force at women's expense. As a result, the state imbued a new relational, gendered analytic onto automobile use and production that remains with western society today.

Dissolved organic matter (DOM) plays a vital role in lake ecosystems, yet its temporal and spatial variations in lakes remain poorly understood. This study investigates DOM dynamics in boreal lakes during the warm season and the Laurentian Great Lakes ice during winter. Sampling 10 boreal lakes in early and late June 2022, revealed subtle changes in DOM in the epilimnion and hypolimnion related to factors such as water residence time and stratification strength. In ice from the Great Lakes, lower dissolved organic carbon concentrations and a higher proportion of protein-like DOM were found compared to water, which mostly contained terrestrial-like DOM. Ice DOM composition varied with factors such as ice thickness, water nutrients, and DOM concentration in ice and water. In addition, we found that the potential release of protein-like DOM from ice to the water during spring melt is considerable and may fuel heterotrophic microbial metabolism.

In situ chlorophyll sensors are beneficial for monitoring of long-term impacts of algal blooms and accessing water quality issues in bodies of water. However, more research is needed to validate their efficacy and understand how environmental conditions can influence sensor measurements. I assessed the performance of an in situ chlorophyll sensor under controlled environmental conditions and used the same sensor to collect vertical phytoplankton patterns in south-central Ontario boreal lakes. The performance of the sensor was assessed by examining the precision of chlorophyll measurements and determining the suitable timing length that would produce precise results. In general, the sensor was relatively insensitive to conditions under lower algal concentrations and the decent of the sensor should be slowed for vertical lake profiling in lakes with higher algal biomass. Most variation resulted from the movement of particle bound algal cells. We described chlorophyll profile characteristics including surface chlorophyll levels and chlorophyll peak depth and width and investigated the relationships of these features with environmental controls. The lakes showed a typical chlorophyll profile of low phytoplankton biomass lakes. Our results showed that dissolved organic carbon was a strong predictor of epilimnetic biomass while light attenuation and dissolved organic carbon were both strong predictors of peak depth. Light attenuation and surface area were small but significant predictors of peak width. We acknowledged that any uncertainties in sensor chlorophyll readings were not an issue in our lakes due to the overall low chlorophyll biomass.

The global shift toward sustainability has prompted brands to promote their sustainability initiatives on social media, aiming to connect with pro-environmental consumers. However, this strategy comes with risks, as social media allows for swift and widespread backlash if consumers perceive greenwashing. The present work examines the impact of social media backlash toward a brand's sustainability initiatives on consumers' purchase intentions. In an experimental study (N = 553), participants were presented social media responses to a fictitious brand's sustainability initiative that were either negative, positive, or a mix of both. The findings indicate that the negative comments decreased purchase intentions for consumers with a pro-environmentalist identity but not otherwise. Moreover, this effect was mediated by decreased perceptions of value-congruence with the brand. This study contributes to larger academic discourses on sustainable marketing, greenwashing, and consumer-brand relationships while providing tangible recommendations to marketing practitioners attempting to mitigate the challenges posed by social media backlash.

Sustainable housing is crucial for immigrant settlement and integration in their host countries. This research focuses on achieving sustainable housing for one racialized immigrant group in Toronto. A concurrent mixed-method approach, which involves simultaneous collection and analysis of quantitative and qualitative data, was used to explore how a racialized immigrant group, like Ghanaian immigrants in Toronto, struggle to achieve sustainable housing in Toronto. The quantitative method involves a survey of 145 Ghanaian immigrants, while the qualitative approach includes in-depth interviews with 10 key informants of Ghanaian immigrants in Toronto. Various quantitative data analysis techniques, including univariate and bivariate, were used to examine the relationships between socio-demographic variables and housing conditions of Ghanaians in Toronto. The findings from the quantitative data suggest that, while certain variables, such as gender and age, have no significant influence on sustainable housing attainment, factors such as immigration status, occupation, and income play an important role in determining the likelihood of achieving sustainable housing. For Ghanaian immigrants in Toronto, these factors impact their abilities to achieve sustainable housing. The qualitative data were explored using thematic analysis, which involved identifying recurring themes and patterns. The qualitative interviews revealed themes of barriers to sustainable housing, such as issues of affordability and accessibility. Overcoming these obstacles promotes immigrants' successful settlement and integration. These findings can be used by policymakers, housing providers, and community organisations to develop targeted interventions to address the housing needs of racialized immigrant groups in Canada. This thesis emphasises the importance of sustainable housing for Ghanaian immigrants in Toronto and informs evidence-based policies and practices. It adds to existing knowledge on immigrant housing experiences and serves as a resource for future research on sustainable housing for diverse immigrant populations in Canada and beyond.

This research explores how the value of sustaining the natural world could become foundational to senior level policy decisions in Canada and how Indigenous Knowledges and Peoples could play a key role in such a paradigm shift. It is a trans-disciplinary study that draws on scholarship in Indigenous Studies, Sustainability Studies and Public Policy and existing report recommendations and policy documents that highlight both historical and recent governance trends in the area of sustainability. These sources help to describe both the challenges and the art of the possible in achieving a policy paradigm shift in Canada. The focal point is a series of conversations with seventeen highly experienced Indigenous and non-indigenous policy leaders from across Canada and across traditional territories. The findings reveal that many participants strongly agreed that a paradigm shift should occur and that both Indigenous and western worldviews are needed to realize it, with none disagreeing. They also point to significant changes that are needed to move from paradigms where shorter-term economic development decisions take precedence over environmental concerns to understanding that a healthy economy and society are dependent upon the natural world. To this end, they provide recommendations such as embedding the Right to a Clean Environment in federal legislation and learning from consensus and culturally based governance models in the North West Territories, Nunavut and New Zealand. They suggest mandating education and awareness programs for civil servants and elected officials on Indigenous -Canada relations and sustaining the natural world upon which Canada is situated and upon which treaties are based. They emphasize that a culture shift requires more Indigenous Peoples in senior leadership roles and to be more meaningfully involved in policy processes. Overall, the conclusion finds that a paradigm shift requires positive relationships between parliamentary governments and Indigenous peoples that enable both Knowledge Systems to come together to put the natural world at the foundation of senior-level policy decisions. Qualities such as respect, listening, trust, reciprocity, responsibility and connectedness with the natural world are highlighted through real-world examples that show that, although it may take time, a paradigm shift is possible and may have already begun. Next steps suggest new approaches for building relationships into the policy cycle.

This thesis examines the ways in which body image is discussed in online settings. There are three different communities discussed: body positivity, proED (pro-eating disorder), and body neutrality. Both body positivity and proED content are fairly popular online, and both have found significant support and followers on various social medias. In this thesis, I argue that both of these types of content cause significant harm to those who engage with them, primarily because both communities (though different in their approaches to body image) work to uphold the thin ideal. I then bring up the third type of content: body neutrality. Body neutrality has not been given the same academic attention as body positivity and proED content, likely due to its relative infancy. In this thesis, I propose body neutrality as a much healthier way to frame body image online because of its completely neutral stance on fat, thinness, and general body image. Though any work relating to social media is quickly out of date, I hope that this thesis provides an overview of body neutrality and how, in its current form, it provides a more balanced approach to online body image discussions.

The goal of this dissertation is to formulate a critique of embodiment through the lens of Lacanian psychoanalysis and in the context of digital media and intelligent technologies. Along with psychoanalysis, our research methodology and philosophy are informed by Badiou's philosophy of the event, Stiegler's philosophy of technics and infrastructuralism in media studies. Our study aims to uncover and articulate the implicit conditioning by the primordial trauma constitutive of the subject's encounters with the medium. In our analysis of embodiment, we make extensive use of psychoanalytic concepts such as: the breach, the lack, the signifier, the construction of the object, the object-a, the transitional object, fetishism and phobia. Each of the four parts of the dissertation approaches the topic from a specific angle, such as the theoretical critique of the basic concepts of the subject and object, the function of the metaphor in the context of intelligent technologies, the role of technological infrastructure in the embodiment of the trauma, the construction of a transitional object such as a pop song in the context of technological dystopianism. We demonstrate that the cognitivist presumption concerning the pivotal role of intellectual motivation behind the subjective attachment to information technologies can be significantly shaken from the point of view of the psychoanalytic understanding of drives and jouissance. On the basis of Alain Badiou's argument, we show the limitations of structurally-determined forms of embodiment considered by psychoanalysis and draw a dividing line between them and the more rare cases of the subjectivation by events suggested by Badiou's theory. We discuss Badiou's concept of the work of truth as an advanced alternative to the psychoanalytic concept of the object and the paradigm of the construction of the (transitional) object. We distinguish the Badiouian concept of the event from the idea of technological/digital disruption, on the one hand, and correlate the latter with the problems discussed in psychoanalysis such as the foreclosure of the Name-of-the-Father and the crisis of the paternal metaphor along with the problems of the futurity and the disruption of intergenerational communication discussed by Bernard Stiegler on the other.

The neuronal ceroid lipofuscinoses (NCLs), commonly known as Batten disease, are a family of inherited neurodegenerative lysosomal storage disorders. CLN7 disease is a subtype of NCL that is caused by mutations in the MFSD8 gene. MFSD8 encodes a lysosomal transmembrane protein that is predicted to play a role in transporting small substrates across membranes. However, little is known about its role and substrate specificity. Previous work identified an ortholog of human MFSD8 in the social amoeba Dictyostelium discoideum and reported its localization to endocytic compartments. In this study, the effects of mfsd8 loss during Dictyostelium growth and multicellular development were further characterized. Dictyostelium mfsd8- cells displayed increased rates of proliferation and pinocytosis in liquid media. During growth, loss of mfsd8 altered lysosomal enzymatic activities and reduced the intracellular and extracellular levels of autocrine proliferation repressor A. mfsd8- cells grown on a lawn of bacteria formed plaques in a shorter period of time compared to WT cells, providing additional support for the enhanced growth of mfsd8- cells. Upon starvation, the aggregation of mfsd8- cells was delayed, and mfsd8- cells formed more mounds that were smaller in size, which may be attributed to the reduced cell-substrate adhesion and altered lysosomal enzymatic activities observed for mfsd8- cells. Following aggregation, tipped mound formation was delayed, however, loss of mfsd8 did not affect the timing of slug/finger and fruiting body formation. Additionally, slug migration was reduced in mfsd8- cells. These aberrant phenotypes, excluding fruiting body formation, were effectively or partially rescued when Mfsd8-GFP was introduced into mfsd8- cells. Overall, these results show that Mfsd8 plays a role in regulating growth and developmental processes in Dictyostelium via lysosomal-associated functions.
