Indigenous Knowledge in Contemporary Public Education
This study provides important perspectives and guidance for educators in Ontario to assist in integrating Indigenous content into public education programs – both in schools and other community educational settings. It explores how Indigenous worldviews provide unique insights for holistic education and learning how to live sustainably in place. The study also focuses on approaches to education, comparing Eurocentric and Indigenous philosophies and pedagogies, as indicators of differing value systems. Through a combination of literature review and personal interviews with eleven influential Indigenous and non-Indigenous educators in the Peterborough area, the study explores the potential for Indigenous perspectives to enhance the wellbeing and personal learning journey of all students, regardless of their backgrounds. The research concludes with recommendations for educators on how to begin integrating Indigenous Knowledge throughout programming in appropriate, respectful ways that celebrate diversity, develop positive relationships and build healthier, more sustainable communities.

Making eDNA count
Environmental DNA (eDNA) is rapidly becoming an established method for the detection of species in aquatic systems and has been suggested as a promising tool to estimate species abundance. However, the strength of the relationship between eDNA concentrations and taxon abundance (density/biomass) can vary widely between species. I investigated the relationship between eDNA concentration and species abundance using two common and closely-related amphibians in eastern North America, the wood frog (Rana sylvatica) and northern leopard frog (Rana pipiens). I manipulated tadpole density in 80 L mesocosms and documented the relationship between tadpole density, biomass, and eDNA concentration. Species were comparable in biomass but differed in the amount of detectible genetic material produced; density and biomass were the superior abundance metric correlated with eDNA concentration for wood frogs and leopard frogs, respectively. However, increases in eDNA concentration reflected increasing tadpole biomass, therefore biomass is likely a better metric of abundance than density. Overall my findings support that eDNA concentration can be used as an index of species abundance, but that species-specific calibration may be needed before eDNA concentration can be effectively translated to an abundance metric. Future research should refine our understanding of how biotic and abiotic factors influence eDNA production, degradation, and recovery across species, before the method can receive widespread use as a monitoring tool in natural settings.

Discriminating grey wolf (Canis lupus) predation events in a multi-prey system in central Saskatchewan
I investigated if spatio-temporal behaviour of grey wolves (Canis lupus) determined via GPS collar locations could be used to discriminate predation events generally, and among prey species, in Prince Albert National Park during winter, 2013-2017. I used characteristics of spatio-temporal GPS clusters to develop a predictive mixed-effect logistic regression model of which spatial clusters of locations were wolf kill sites. The model suffered a 60 % omission error when tested with reserved data due to the prevalence of deer kills with correspondingly low handling time. Next, I found a multivariate difference in the percentage of habitat classes used by wolves in the 2 hours preceding predation events of different prey species, suggesting that wolf habitat use reflects prey selection at a fine-scale. My results highlight the difficulty and future potential for remoting discriminating wolf predation events via GPS collar locations in multi-prey ecosystems.

Solving Differential and Integro-Differential Boundary Value Problems using a Numerical Sinc-Collocation Method Based on Derivative Interpolation
In this thesis, a new sinc-collocation method based upon derivative interpolation is developed for solving linear and nonlinear boundary value problems involving differential as well as integro-differential equations. The sinc-collocation method is chosen for its ease of implementation, exponential convergence of error, and ability to handle to singularities in the BVP. We present a unique method of treating boundary conditions and introduce the concept of the stretch factor into the conformal mappings of domains. The result is a method that achieves great accuracy while reducing computational cost. In most cases, the results from the method greatly exceed the published results of comparable methods in both accuracy and efficiency. The method is tested on the Blasius problem, the Lane-Emden problem and generalised to cover Fredholm-Volterra integro-differential problems. The results show that the sinc-collocation method with derivative interpolation is a viable and preferable method for solving nonlinear BVPs.

Community, Complexity, and Collapse
The city-state of Minanha, located in west central Belize, reached its zenith and most culturally complex stage by the Late Classic period, 675-810 AD. Only a century later, its royal court “collapsed”. The Contreras Valley is a small farming community located in a settlement zone south of Minanha. Decades of research at Minanha and the analysis of artifact frequencies from commoner households allow for a better understanding of the intra- and inter-community social practices occurring at the site of Contreras Valley and within the greater Minanha area. An Archaeology of Communities as well as Resilience Theory frameworks are utilized to explore the integrative social, political, and economic strategies of this commoner population. These theories are used to better understand the developmental history of the royal court from the perspective of the peripheral commoners, who sustained a population while the royal court disintegrated. Furthermore, this thesis focuses on the intersection of resilience and communities, and how the Contreras Valley experienced phases of resilience as well as vulnerability throughout its history. The resilience of this group of individuals will generate an increased cognizance of how a community copes with and continues to thrive in a climate of political chaos and instability.

Sowing the seeds of Canada's future agroecological farm(er)s
There are many barriers facing new, sustainably-focused, agriculturalists in Canada including access to land, capital, markets and practical training. These challenges are compounded by the flawed but powerful figure of the industrial agriculture model, a rapidly aging farmer population, changing demographics, and subsequent loss of valuable, place-based agricultural knowledge. This thesis argues that there is a need for innovative formal education programs that combine traditional classroom with practical hands-on learning in collaboration with local experts. As such, this exploratory case study looks at how a farm incubator can function as a site for experiential education and a means of addressing some of the barriers to entry faced by new agroecological farmers. The findings show that those seeking experiential sustainable agriculture education benefit greatly from having a site, such as a farm incubator, to learn the skills that accompany their knowledge while building their agricultural community and increasing their confidence.

Virtual Voices
A consistent provincial approach to capacity planning for rehabilitative care had been identified as a critical gap in the field of health care in Ontario (Rehabilitative Care Alliance, 2015a). In response, the rehabilitative care alliance (RCA) developed a needs based hip fracture capacity planning canvas together with persons and families. This research utilized computer assisted participation (CAP) to gather additional perspectives from Virtual Voices via an on-line survey. The results of the Virtual Voices survey were compared to Ontario’s RCA hip fracture patient focus group findings. CAP facilitated more voices and more ideas through virtual engagement. The survey method required 97% (10.6 hours) less time than the focus group. The Virtual Voices respondents provided validation of the focus groups’ confirmation of the rehabilitative care needs, locations and most core team members as well as identified new ideas. The results support the implementation of a needs-based capacity plan that enables individualized care planning. This research provides a blueprint for the ongoing engagement of persons and families in the co-creation of a sustainable rehabilitative care system. A dashboard and e-health app would enable ongoing co-design, monitoring and evaluation.

Hiya 'aa ma pichas 'ope ma hammako he ma pap'oyyisko (Let Us Understand Again our Grandmothers and our Grandfathers)
The Tamalko (Coast Miwok) North Central California Indigenous people have lived in their homelands since their beginnings. California Indigenous people have suffered violent and uncompromising colonial assaults since European contact began in the 16th century. However, many contemporary Indigenous Californians are thriving today as they reclaim their Native American sovereign rights, cultural renewal, and well-being. Culture Bearers are working diligently as advocates and teachers to re-cultivate Indigenous consciousness and knowledge systems. The Tamalko author offers Indigenous perspectives for hinak towis hennak (to make a good a life) through an ethno-autobiographical account based on narratives by Culture Bearers from four Indigenous North Central California Penutian-speaking communities and the author’s personal experiences. A Tamalko view of finding and speaking truth hinti wuskin ʼona (what the heart says) has been the foundational principle of the research method used to illuminate and illustrate Indigenous North Central California consciousness. Author Keywords: Consciousness, Culture Bearers, Indigenous, North Central California, Penutian, re-cultivation
Model for the Differential Susceptibility of Strontium Titanate
The appearance of a two-dimensional electron gas (2DEG) in oxide interfaces between strontium titanate (STO) and other materials has become a major area of study. The behaviour of the 2DEG in STO is not well understood in part because the dielectric properties of STO are not well characterized. The differential susceptibility has a major impact on the electric fields within strontium titanate, and therefore to understand the 2DEG a better understanding of the susceptibility is needed. An expression for the soft mode phonon frequency of bulk strontium titanate is derived and used to model the susceptibility as a function of spatially homogeneous electric field, temperature and wavevector. This model is used to discuss the effect of spatially inhomogeneous electric fields and the local vs. nonlocal nature of the susceptibility. The critical exponents and the free energy are determined and discussed. Author Keywords: critical exponents, differential susceptibility, quantum paraelectric, strontium titanate
'This is where the poetry comes out'
Since 1984, poetry slams have emerged as a politicized expressive movement of performing the personal and political through poetry competitions. Slams are also discursively spatialized, often represented as “spaces” that are “safe,” “inclusive,” etc. In this thesis, I investigate how, why, and to what effect the Peterborough Poetry Slam produces, consolidates, and challenges such “resistant spaces.” Drawing on interviews and participant observation, I consider how the slam’s reiterative practices facilitate its space-making by encouraging performances that resist, reimagine, and sometimes inadvertently reify dominant societal norms. I argue that this space-making is imperfect yet productive: though not resistant space in any straightforward or static way, the slam continuously produces possibilities to challenge norms and confront power. This thesis contributes to scholarship on performative space and creative resistance movements. In an era when political resistance to power structures is often silenced, this research offers insights of potential significance to other resistant space-makings. Author Keywords: Nogojiwanong Peterborough, performative space, poetry slam, resistance, space-making, spoken word
Enhancing forensic entomology applications
The purpose of this thesis is to enhance forensic entomology applications through identifications and ecological research with samples collected in collaboration with the OPP and RCMP across Canada. For this, we focus on blow flies (Diptera: Calliphoridae) and present data collected from 2011-2013 from different terrestrial habitats to analyze morphology and species composition. Specifically, these data were used to: 1) enhance and simplify morphological identifications of two commonly caught forensically relevant species; Phormia regina and Protophormia terraenovae, using their frons-width to head-width ratio as an additional identifying feature where we found distinct measurements between species, and 2) to assess habitat specificity for urban and rural landscapes, and the scale of influence on species composition when comparing urban and rural habitats across all locations surveyed where we found an effect of urban habitat on blow fly species composition. These data help refine current forensic entomology applications by adding to the growing knowledge of distinguishing morphological features, and our understanding of habitat use by Canada’s blow fly species which may be used by other researchers or forensic practitioners.

Stopover Movement Patterns by Blackpoll and Canada Warblers Across Southeastern Canada During Fall Migration
Stopover ecology is a topic that surges in relevancy as choices made by migrants during stationary periods (stopover sites) may not only have important individuals’ fitness consequences but also can affect population dynamics. I used MOTUS automated telemetry array to study fall stopover duration of Blackpoll Warbler (BLPW) and departure decisions of BLPW and Canada Warbler (CAWA) in relation to various predictors. I affixed radio-transmitters on 55 BLPWs and 32 CAWAs at two banding stations in Ontario in September-October 2014-2015. Radio-tagged individuals were tracked through the MOTUS network across southeastern Canada. I developed models relating age class, fat score, Julian date and stopover movement types to Blackpolls’ stopover duration. I also examined whether there were species-related differences of wind selectivity when resuming migration. No explanatory variable significantly influenced BLPW’s stopover duration. Both species tended to depart under increased tailwind assistance, but with no difference in the effect of wind conditions between the two species. This study provides further evidence supporting the relevance of local wind conditions as a key factor affecting the departure likelihood, especially when migrating birds face an ecological barrier. Author Keywords: Cardellina canadensis, departure decisions, minimum stopover length, MOTUS, overland fall migration, Setophaga striata
