Green Leadership in the Classroom
Concerns about climate change means that there is an urgent need to understand teachers’ role in educating students about environmental issues and sustainability. However, little is known about teachers’ environmental leadership and how that affects their competencies in the classroom, their general well-being and connections with nature, or what kinds of personality characteristics shape these teachers. A sample of current, future, and past Canadian teachers (N = 260) completed an online survey which included quantitative and qualitative questionnaires. Correlational and regression analyses determined teachers who possess environmental leadership qualities have a greater connection with nature, more positive well-being, and are more confident in their abilities to teach students outdoors. Furthermore, positive personality traits predict teachers’ environmental leadership. Qualitative data revealed both structural and psychological barriers reduced the likelihood of teachers taking students outdoors and that greater support, resources and training are needed to enable teachers to implement more nature-based learning. Author Keywords: competence, environmental leadership, nature relatedness, personality, teachers, well-being
On Forests, Witness Trees, and Bears
This dissertation is about Forests, their loss and the grieving that arises from their loss. The loss of ancient and old-growth forests by way of clearcutting and or anthropogenically driven disturbances, including climate change, presents the quandary of loss of both biological and cultural diversity. Following Umeek’s/E. Richard Atleo’s term, I suggest that “dis-ease” in the dominant relationship to forests in parts of the Western world significantly rests within inherited cultural and political pasts at play in the present, carried in much of the language and lifeways of modern Anglophone societies today. I do so by a critical topographical exploration of thematic patterns that go back to the Epic of Gilgamesh, the oldest written account of deforestation in the history of Western civilization. I offer at the center of my inquiry a collection of witness trees as North American case studies. Each tree is a witness object, a station from which I confront and explore social-ecological grief as it has accumulated over time from English colonization, with one focusing on Indigenous cultural reclamation and place-based ecological co-management. Lastly, I turn to a multispecies exploration of social-ecological grief, using bears in North America as a face for reflection and consider who and what more is lost when old forests are degraded and gone. By asking the place question—“what place is this?”—of forests, or the Forest Question, my dissertation is thus an exploration of the connection and responsibilities to other place-based human and other-than-human communities in a rapidly changing climate. Author Keywords: critical topography, environmental grief, forests, multispecies, social-ecological relations, witness trees
Speaking of Being
The central question of this research is “What is poetry?” The ambiguity and unintelligibility of the question itself forces the writing to take two different approaches to it. The first approach is to define poetry not by what it is but by how it is related to the human being and to the world. Seeing poetry as its relation to Being allows a definition of poetry based on its function. This approach draws on philosophical discussions how poetry is related to the human and how Being can be extended into poetic creation. Martin Heidegger’s move from seeing poetry as the possibility of worldmaking to seeing it as a place of dwelling, and, in his later works, as unconcealment and the extension of Being as the House of Being, marks the direction of philosophical discussions in this paper. In this sense, poetry is defined as a creative possibility, where the speaking being comes in close contact with the speaking things and speaks of being.The second approach is to define poetry not as a whole but as some of its essential parts, as “poetic imagination” for instance. This attempt to define the poetic imagination draws on long-running discussions of imagination, metaphor, metaphorical thinking, image and imaging. It also relies on Freud’s discussions of how dreams function as textual phenomena: the poetic imagination, this approach argues, is similar to dreaming. The poet’s conscious and unconscious engagements with language create an uncanny experience where the relation between object and its poetic image is simultaneously known and unknowable. The third part of this study focuses on Lacan’s move from the symbolic unconscious to the real unconscious, in order to shed light on how the real is related to its linguistic reality. This brings the discussion to a point where language is replaced by lalangue in order to knot the real directly to the symbolic. Author Keywords: poetic creation, poetic imagination, poetry
Oil is Thicker than Justice
This thesis provides a comprehensive overview of the extractive industry operating out of the Alberta tar sands region to determine how environmental violence is enacted against Indigenous women, girls, and queer or Two-Spirit peoples in the Lubicon Lake Cree Nation and beyond. Through an analysis of existing literature in the field, a case study on the Lubicon Lake Nation and a policy analysis of the Calls for Justice from the Final Report of the National Inquiry into Missing and Murdered Indigenous Women, this thesis draws links between industrialization, capitalism, the heteropatriarchy, and colonialism. Finally, this thesis offers a pathway to resurgence, through the subversion of colonial gender and sexual norms, and collective action to reclaim Indigenous territory as an alternative to state-sponsored solutions and policies. Author Keywords: Colonial heteropatriarchy, Environmental violence, Land Back, Lubicon Lake, Tar sands, Violence against Indigenous women
Does boredom lead to ego-depletion? Examining the association between boredom and ego-depletion
Ego-depletion refers to the observation that using self-control at Time 1 (T1) in the sequential-task paradigm leads to worse self-control at Time 2 (T2; Baumeister et al., 1998). Self-control is often manipulated by varying the difficulty of the task used at T1. Recently, Wolff and colleagues (2020) suggested that failures to replicate the ego-depletion phenomenon may arise because simple tasks may be boring, therefore requiring self-control to maintain attention on the task. Three experiments (Experiment 1, N=60; Experiment 2, N=61; Experiment 3, N=59) are reported that examined whether boredom at T1 predicted self-control at T2. A simple Go/No-Go task was used at T1. The ratio of Go to No-Go trials was changed across experiments to explore how the properties of the boring task impacted the association between boredom and self-control. When responding was frequent, increased boredom at T1 was associated with fewer anagrams correctly solved (Experiment 1 and 3), and more self-reported fatigue at T2 (Experiment 1), consistent with boredom leading to ego-depletion. However, when responding was infrequent (Experiment 2), increased boredom at T1 was associated with more correctly solved anagrams at T2, suggesting that the properties of a boring task change the psychological outcome that task has on self-control. Author Keywords: attention, boredom, ego-depletion, executive function, self-control
What Happens in Childhood, Does Not Stay in Childhood
Researchers have found associations between attachment, childhood adversity, and posttraumatic stress symptoms; however, the underlying mechanisms between these variables remains unknown. The present study explored the moderating effects of childhood adversity on the relationship between adult attachment and posttraumatic stress symptoms in two samples. In total, 533 undergraduate students and 357 individuals recruited from online communities completed measures of childhood adversity, adult attachment, and posttraumatic stress symptoms. Hierarchical regression analyses were used to test the moderating effect on childhood adversity. One-way ANOVA post hoc analyses were run to assess mean differences of attachment and posttraumatic stress across five childhood adversity groups. The results suggested that attachment and childhood adversity do predict posttraumatic stress symptoms; however, there was no significant moderating effect of adversity found. The post hoc analyses revealed significant mean differences for secure attachment, avoidant attachment, and posttraumatic stress symptoms. The findings suggest that attachment and childhood adversity are significantly associated with posttraumatic stress symptoms. Author Keywords: adult attachment, childhood adversity, posttraumatic stress symptoms, trauma
The Relations Between Identity Developmental Processes, Study Habits, and Academic Performance
Adolescence is a time when young people focus their attention on setting and pursuing long-term goals. Contemporary approaches of identity development focus on three pivotal processes underlying the identity formation process and the maintenance of one’s identity (e.g., core values, etc.). These processes are commitment (commitments to a goal), in-depth exploration (exploration of choices and options), and reconsideration of commitment (feelings of uncertainty about current commitments). The primary purpose of the current study was to examine the relations between identity processes, study habits, and academic performance in 45 female undergraduate students (M age = 21.00). Utilizing a self-report measure, findings suggested a significant positive relation between educational and relational commitment, as well as reconsideration of commitments in the educational domain and reconsideration of commitments in the relational domain. In terms of identity processes and grades, a regression analysis revealed that educational reconsideration of commitments predicted academic performance. Further, for those employing poor study habit skills, educational reconsideration of commitment predicted academic performance. The present study offers insight on the importance of assessing adolescent’s uncertainty of educational and relational commitments, while also highlighting the protective factor of maintaining good study habit strategies. Author Keywords: academic performance, adolescence, educational, identity, relational, study habits
Ê-NITONAHK MIYO-PIMÂTISIWIN (SEEKING THE GOOD LIFE) THROUGH INDIGENOUS DANCE
This thesis is about the ways in which Indigenous dance serves as a social determinant of Indigenous health and well-being. Utilizing both contemporary and traditional versions of the Medicine Wheel for the framework, analysis and organization of the thesis allows for a holistic perspective which includes the spiritual, physical, emotional and mental aspects. The importance of Indigenous dance for Indigenous health and well-being is confirmed through: existing literature; interviews with Indigenous choreographers, dancers, theatre artists, and performers; Indigenous exponents of the forms; and Indigenous Elders. In order to contextualize current practices of Indigenous dance, the history of Indigenous dance in relation to colonization is presented. The research and experiences of co-researchers show the need for Indigenous dance and culture to be supported as a social determinant of health and well-being. Author Keywords:
Functional Variation within Middle Paleolithic Ground Stone Tools
In the southern Levant, ground stone tools (GST) provide insight into early plant food exploitation, butchery, and cognition. Outside of these examples, GST evidence is scarce, particularly for the Middle Paleolithic. An extensive assemblage of GST recovered from Nesher Ramla, an open-air hunting camp in Israel, presents the unique opportunity to study the role of GST within Middle Paleolithic behaviour. Use-wear and residue analysis, together with replication experiments are employed to investigate GST function within a specific period of site use by focusing on GST from the Upper Sequence (Units I-II) which reflects a trend of decreasing site-use intensity. The results indicate that GST were employed for bone breaking and knapping during the final phases of occupation while comparison with Unit V suggests longer occupations involved more diverse and extensive use of GST. GST at open-air sites are also proposed to represent a strategy for intensive exploitation of location-specific resources.

Heteronormativity in Virtual World Design
The purpose of this research is to highlight the limitations and opportunities for playful expression of gender identity in character creation systems of virtual worlds, and how these might work to reinforce, or disrupt, the heteronormative imperative. The primary sites considered in this analysis are the video game World of Warcraft and the live action role-playing game Amtgard. I provide evidence that while the World of Warcraft’s character creation system is sexist and works to reinforce heteronormative ideology, Amtgard’s relatively ambiguous design provides opportunity for disruption of these norms. Participant research with Amtgard players demonstrates actual instances of Amtgard’s more flexible character creation system being utilized in expression and exploration of gender identity which resists the heteronormative imperative. Based on this, I call on game developers to reject designs which necessitate selection of gender from within the traditional binary and embrace more ambiguous design in development of character creation systems.

Particulate Matter Component Analyses in Relation to Public Health in Canada
This thesis explores the shot-term relationship between exposure to ambient air pollution and human health through metrics such as mortality and hospitalization in Canada. We begin by detailing the organization and interpolation of air pollution data from its partially quality-controlled source form. Analyses of seasonal, regional and temporal trends of all major components of PM2.5, was performed, showing a seasonal variation across most regions and validating the dataset. A one-pollutant statistical Generalized Additive Model was applied to the data, estimating the health risk associated with exposure to thirteen different components of PM2.5. The selected components were based on those that compromised the majority of the mass and included: sulphate, nitrate, zinc, silicon, iron, nickel, vanadium, potassium, organic carbon, organic matter, elemental carbon, total carbon. Trends based on annual estimates of the association for PM2.5, and its constituents,were compared, showing that carbonaceous compounds, sulphate and nitrate had similar estimates of association. Many estimates, as is common in population ecologic epidemiology, had association estimates statistically indistinguishable from zero, but with clear features of interest, including evident differences between cold and warm season associations in Canada's temperate climate. A method to model two correlated pollutants (in this case, PM2.5 and O3) was developed using thin plate splines. In this approach, the location of the response surface (after accounting for the temperature, a smooth function of time and day of week) that corresponds to the average pollutant concentration and the average plus one unit was used as the estimate of the joint contribution of pollutants due to a unit increase. The estimates from the thin plate spline (TPS) approach were compared to the single pollutant models, with large increases and decreases in PM2.5 and O3 being captured in the TPS estimates. However, this approach indicated significantly larger error in the estimates than would be expected, indicating a possible future area for refinement. Author Keywords: Air pollution, Environmental Epidemiology, Generalized Additive Models, Human Health, Multivariate Models, Thin Plate Splines
Use and Utilization of Loose and Commingled Human Dental Remains in Investigations of Ancient Human Populations
Commingled teeth present a unique opportunity for a novel application of standard methodological approaches commonly utilized in dental anthropological studies. Unfortunately, little research has been conducted on loose or commingled dental assemblages to determine if they are suitable samples for reconstructing bioarchaeological narratives of ancient human populations. The lack of research on commingled dental samples is surprising, given that teeth are highly resistant to post-depositional deterioration and are often some of the only remains left in high deteriorated burials. An experimental analysis of a commingled dental assemblage recovered from four chultuns at Ka'kabish, Belize, was conducted to address this lack of research and provide a real-world example of the potential use and utilization of commingled dental assemblages in investigations of ancient human populations. Author Keywords: Anthropology, Belize, Commingled, Dental, Maya, Methods
