Sexting and Satisfaction
Sexting was explored in relation to cohabitation status, general and sexual communication, as well as the anxious and avoidant dimensions of attachment. The present study was focused the distinction between lifetime and recent sexting, in an attempt to more accurately assess the relationships between the examined factors and sexting behaviours. Individuals in long-distance relationships were more likely to report recently sexting and engaged more frequently than those in cohabitating relationships, but did not differ in their levels of sexual satisfaction. Recent sexters reported higher levels of sexual communication compared to lifetime sexters, and sexual communication was positively, though weakly, correlated with sexting frequency. The present study was unable to support a predictive relationship between recent sexting and levels of attachment anxiety or avoidance. These results highlight the importance of exploring the context in which sexting occurs, as well as distinguishing between lifetime and recent sexters in future sexting research. Author Keywords: Attachment, Long Distance Relationship, Recent Sexting, Satisfaction, Sexting, Sexual Communication
Growth and Revitalization in Peterborough ON
The Places to Grow Act (2005) and the Growth Plan for the Greater Golden Horseshoe (2006) are two pieces of legislature passed by the Government of Ontario to help govern and limit urban sprawl in major cities across Ontario through to 2041. These policies are framed around the development and maintenance of large-scale cities. While there are some provisions within these policies for mid-sized cities that are part of the Greater Golden Horseshoe (GGH), there are few resources, case studies, and models for successful revitalization, and intensification in mid-sized cities. The goal of this thesis is to answer questions related to planning and development in Peterborough, Ontario and to assess its progress as it relates to Places to Grow (2005) and the Growth Plan for the Greater Golden Horseshoe (2006) guidelines. Through the use of library research, policy document analysis, interviews with key stakeholders, and GIS analysis, I identify both strategies and challenges related to development and growth in Peterborough, ON. I conclude that the policies are proving to be initially favorable in their results, however it is not without significant challenge to Planners and stakeholders in Peterborough, ON. Finally, I suggest further research take place in order to further assess the effectiveness of these policies in other mid-sized cities in Ontario, as well as to measure the success of the policies closer towards the 2041 deadline.

Dissent Denied
In June 2010, the Group of Twenty (G20) met in Toronto, Ontario. The summit drew large-scale protests that culminated in mass arrests and extensive civil rights violations. Given these outcomes, this thesis examines the security spectacle of the summit to assess the evolving state of public order policing and social movement protest in Canadian law and politics. Connecting the securitization of the summit to the politics of neoliberalism, I argue these overlapping forces helped foment the criminalization of political dissent during the 2010 Toronto G20. Author Keywords: mega-events, neoliberalism, public order policing, securitization, security, social movements
Applications of Immersive Virtual Reality Technologies for Archaeology
This MA thesis discusses the applications of immersive virtual reality technologies as a tool for studying archaeological excavation processes. The excavation of a structure at the Nassau Mills, a twentieth century milling complex in Peterborough, Ontario, is used as the case study. Structure from Motion (SfM) photogrammetry is used to digitize each excavation day as 3D models. These excavation days are visualized in the Nassau Mills Pavilion, which enables users to revisit the site on each excavation day, and view and measure structural contexts. This thesis explores a number of theories including: affordance theory, phenomenology, theories of perception, and spatial accuracy. It also discusses multi-user presence, spatial thinking, and wayfaring as notions for improving the way users collaborate, share, and study digitized archaeological data in virtual environments. This thesis offers new approaches to using supplementary digital recording techniques for archaeological excavation while providing a new VR collaborative platform for digitizing and disseminating archaeological data. Author Keywords: Archaeological Database, Digital Archaeology, Multi-User Collaboration, SfM Photogrammetry, Spatial Thinking, Virtual Reality
Geospatial Analysis of Late Paleoindan Hi-Lo Points in Ontario and New York
This thesis analyzes variability in a sample (n=302) of late Paleoindian Hi-Lo points from Ontario and New York. Biface variability is recorded using landmark geometric morphometrics. Raw material data is used to assess Hi-Lo toolstone usage patterns and the impact of raw material constraints on manufacture. Statistical analyses are used to assess patterning of variability in space. Spatial results are interpreted using cultural transmission theory in terms of their implications for the geographic scale of social learning among Hi-Lo knappers. Results of the spatial analyses are related to theory about hunter-gatherer social networks in order to understand the effects of hypothesized settling in processes on late Paleoindian knappers. Results indicate random spatial patterning of Hi-Lo variability. The absence of spatial autocorrelation for Hi-Lo size indicates that settling in processes were not sufficiently pronounced during the late Paleoindian period to manifest as inter-regional variability within the Hi-Lo type. Author Keywords: Biface Variability, Cultural Transmission, Geometric Morphometrics, Hi-Lo, Late Paleoindian, Ontario
Effects of Ideological Conformity on Foreign Policymaking
During the 1970s, ideological divisions caused by divergent interpretations of the American failure in Vietnam permeated the world of foreign policymaking. This led to a concern among the architects of the Reagan administration that foreign policymaking had become incoherent. They attempted to mitigate the effects of this disharmony by re-establishing a workable degree of ideological conformity within the foreign policy bureaucracy. This thesis focuses on the strategy used to improve ideological conformity and its effect on the foreign policy bureaucracy’s ability to produce well informed policy. Using case studies of two of Reagan’s ambassadors to Central America, it argues that Reagan’s strategy created a foreign policy bureaucracy that manufactured uninformed policy. The influence granted to officials who based their recommendations on regional expertise was severely curtailed. This shift produced a subsequent change in diplomatic practice, as foreign service officers adapted to the demand for allegiance to the president’s agenda.

Barriers and Facilitators to Indigenous Knowledge Incorporation in Policy Making
The inclusion and application of Indigenous Knowledge (IK) has become a central and often demanded element of policy making involving Indigenous peoples. However, there are very few examples that exist in the literature and elsewhere that show how IK can be effectively integrated into decisions, policies, and programs. In response to these challenges, this research explored what processes are used to incorporate IK into policy and their effectiveness through the development of a framework that sought to identify critical factors related to IK inclusion. The framework was then applied to evaluate IK incorporation opportunities in the Nunatsiavut case, focusing on the development of the Nunatsiavut Government's Environmental Protection Act. The case study analysis was used to test and provide adaptations to the initial framework. This research identifies the importance of governance structures and processes, community participation and engagement approaches, and IK research and support programming in enhancing opportunities for IK to be integrated and reflected in policy outcomes. The Nunatsiavut case largely supported, but in some cases challenged critical factors of IK incorporation identified in the framework. The findings of this study are valuable for policy and decision makers (both Indigenous and non-Indigenous) regarding approaches and programs that can assist and support IK inclusion into policy processes and decisions. Author Keywords: environmental assessment, Indigenous Knowledge, Inuit Knowledge, Nunatsiavut, policy, self-government
Help Wanted
The purpose of this thesis was to explore the role of attachment in university students’ help-seeking process using both a cross-sectional and mixed methods study. In the cross-sectional study, I explored whether help-seeking attitudes mediated the relationship between attachment and help-seeking behaviour. As expected, the relationship between secure and preoccupied attachment and greater help-seeking behaviour from both informal and self-help sources was partially mediated by positive attitudes toward seeking non-professional personal help. However, unexpectedly, attitudes toward professional psychological help did not mediate the relationship between attachment and formal help-seeking behaviour. In the mixed-methods study, secure students reported positive help-seeking experiences and discussed facilitators of help-seeking. On the other hand, fearful and dismissing students reported more negative help-seeking experiences and discussed barriers to help-seeking. Discussion of findings focus on how university staff can use attachment theory to develop interventions to increase student help-seeking.

Nietzsche and Deleuze
Gilles Deleuze claims that understanding the eternal recurrence as a recurrence of the same is a misreading of Friedrich Nietzsche, yet, this assertion is not supported by Nietzsche’s texts. In all instances where Nietzsche describes the eternal recurrence, he emphasizes that it is one of the same events. One’s willingness to love one’s fate and to will the eternal recurrence of the same represents the psychological state of the Overman and his achievement of joyousness. However, this is at odds with Deleuze and Felix Guattari’s conception of the nomad. Consequently, the nomad and the Overman are not congruous at all. Rather, the nomad is Nietzsche’s lion. The eternal return of the different then describes the psychological state of the lion as a precursor to the psychological state of the Overman. The lion cannot will the eternal recurrence of the same; he must will the eternal recurrence of the different. When the lion becomes the child, he has the psychological perspective within which to will the eternal recurrence of the same. It is in this sense that Nietzsche and Deleuze’s versions of the eternal recurrence are not antithetical – they are complementary and represent a progression of psychological thought. Author Keywords: Eternal Recurrence, Friedrich Nietzsche, Gilles Deleuze, Nihilism, Nomad, Overman
SPAF-network with Saturating Pretraining Neurons
In this work, various aspects of neural networks, pre-trained with denoising autoencoders (DAE) are explored. To saturate neurons more quickly for feature learning in DAE, an activation function that offers higher gradients is introduced. Moreover, the introduction of sparsity functions applied to the hidden layer representations is studied. More importantly, a technique that swaps the activation functions of fully trained DAE to logistic functions is studied, networks trained using this technique are reffered to as SPAF-networks. For evaluation, the popular MNIST dataset as well as all \(3\) sub-datasets of the Chars74k dataset are used for classification purposes. The SPAF-network is also analyzed for the features it learns with a logistic, ReLU and a custom activation function. Lastly future roadmap is proposed for enhancements to the SPAF-network.

Archaeological Investigation of the North Group at Pacbitun, Belize
This thesis reports on the 2010 excavations of the North Group and Eastern Court at the ancient Lowland Maya site of Pacbitun. It provides a construction history of the architecture and an analysis of associated artifacts, burials, and caches. The archaeological investigations demonstrate that the seven structures (Strs. 34-40) of this restricted access plazuela group were built in the Early Classic period, and renewed in the Late Classic period. Based on analyses of artifacts (ceramics and lithics), skeletal and faunal remains, and intra- and inter-site comparisons, the North Group functioned as a secondary elite domestic residential group. Reconstruction suggests that the inhabitants here were not commoners; instead, the occupants probably were related to the ruling elite of Pacbitun. Some of the evidence includes the central location and elevation of the North Group, the presence of red painted plaster surfacing, a burial with multiple ceramic musical instruments, and multiple dedicatory caches with exotic goods (e.g., marine shell, jadeite, "Charlie Chaplin" figures). Author Keywords: Ancient Maya, ceramic musical instruments, Charlie Chaplin figurines, Pacbitun, North Group, Eastern Court, Belize River Valley, Belize, restrictive access plazuela group, secondary elite
Determinants of Deviance
Background: Researchers have provided evidence that attachment may be independently linked to early adversity and criminal behaviour. In this study, I examined the combined associations among these variables in a student and community sample. Method: The first study consisted of undergraduate students (n = 590) who completed surveys to assess early adversity (Felitti, et al., 1988), attachment (Scharfe, 2016), and criminal behaviours. Participants were grouped based on their reports of adverse experiences and engagement in criminal behaviour. The second study was a replication of the first using a community sample (n = 294). Results: My hypotheses were partially supported, and my findings were consistent across Study 1 and Study 2. As I expected, there was a significant main effect for adversity when examining the mean scores of the attachment representations for attachment to mothers (Study 1 F (16, 1763.402) = 3.61, p < .001; Study 2 (F (16, 849.942) = 2.377, p = .002) and attachment to fathers (Study 1 F (16, 1763.402) = 4. 349, p < .001; Study 2 (F (16, 840.776) = 3.067 p < .001)). From examining the means, I concluded that participants who reported greater adversity reported higher insecure-avoidant and lower secure attachment to mothers and fathers. There were no significant main effects for criminal behaviour or significant interaction effects. Impact: To date, no study has explored all three variables explicitly. My findings are able to highlight the critical importance of secure attachment relationships and add further comprehension to exploring factors associated to criminal behaviour. Author Keywords: Attachment, Criminal Behaviour, Early Adversity
