Archaeology of Vagabondage
My research examines the figure of the 'vagabond' as a case study to illustrate how 'modern' perception of the 'vagabond' has depleted the diversities in its 'pre-modern' counterparts. It argues that the paranoia towards the 'vagabond' was inherited from the west out of the colonial contact leading to the birth of the nation-state and its liaison with 'instrumental rationality' during the high noon of advanced industrial capitalism, while (quasi-religious) itinerancy, on the contrary, had always been tolerated in 'pre-modern' India. The problems I am addressing are: What is the line of thread that separates the 'traveler' from the 'vagabond', the 'explorer' from the 'wanderer'? How do we then politically account for the historic 'ruptures' in the vagabond having been tolerated in the ancient 'Indic' thought [cf. Manusmriti, Arthshastra], encouraged in early Buddhist discourse [cf. Samannaphala Sutta], revered as the 'holy Other' in the Middle Ages [cf. Bhakti-Sufi literature], and eventually marginalized in the 'modern'? While considering issues of cultural differences, my thesis points to how the epistemic shifts from the classical to the medieval, from the medieval to the modern radically alter the value system immanent in the figure of the 'vagabond'. The research argues that the cultural baggage that the expression 'vagabond' is generally associated with, is a product of a specific western/utilitarian value system, which is a distinct 'cultural' category of the 'modern' west that had no resonance in 'pre- modern' India, and hence cannot be necessarily universalizable. The project works in a number of registers: historical, archival, cultural, philosophical and representational, involves analysis of literary, filmic texts, also legislative documents, and is genuinely interdisciplinary in nature. As of discourse analysis, the project studies the politics of cultural representations both of and by 'vagabonds'.

Archaeology, Engagement and Local Communities
This research is an ethnographic investigation into the relationships between the Stélida Naxos Archaeological Project and the local population of Vivlos, the region where the team takes their seasonal residence during their annual archaeological field season. Fieldwork in Vivlos revealed the local peoples’ interest in archaeology, local legends, and Greek history. The people’s cultural identity facilitated a sense of communal pride with hosting the archaeologists for their field season. The archaeologists’ ethical considerations and their friendliness towards the locals during their time in Vivlos followed practices affiliated with public archaeology, laying the groundwork for maintaining positive working relations between the two groups.

Are We All on the Spectrum? Assessing Autistic Traits in the HEXACO Personality Framework
Autistic traits are characterized by difficulties with socialization, preference for order, and rigid and repetitive behaviour patterns. This study evaluated the psychometric properties of two measures of autistic traits, the Autism-Spectrum Quotient (AQ) and the Sub-threshold Autistic Trait Questionnaire (SATQ), and their associations with the HEXACO personality framework. The relationships between self-objectification, Need for Cognition (NFC), and autistic traits were also examined. In a student sample (N = 294), autistic traits were found to be negatively related to eXtraversion, but unrelated to self-objectification and NFC. However, individual subscales of the SATQ and AQ revealed different personality profiles, suggesting a non-unitary composition of the autistic trait measures. The AQ’s subscales failed to be represented in its factor structure. Intercorrelations between SATQ and AQ subscales showed that some subscales were uncorrelated with others. These concerns challenge whether autistic traits should be considered as a downwards extrapolation of Autism Spectrum Disorder.

Art of the Sustainable Street
ABSTRACT The Art of the Sustainable Street Miriam L. R. Mutton The street influences our sense of community every day. It is argued that getting the street right communicates a collective vision for action leading to sustainable community. This investigation continues conversations for community repair and resilient change, especially for small town Ontario. The researcher is informed by ways of seeing inspired by Walter Benjamin’s literary montage, The Arcades Project. By method of collecting and connecting information from literature sources spanning several decades and recent interviews, this thesis demonstrates in narrative form the value to community of everyday street details of human scale. Recurrent themes are adopted as technique in validation. Findings are presented from various perspectives including those of the design professional and the politician. The sustainable street enables communication. Research outcomes indicate knowledge transferred through the art of storytelling supports place-making and connection to community. Fragments of information connect into themes defining safe streets which foster trust among strangers, and facilitate citizenship and good governance. Key words: sustainable community, citizenship, safe streets, Benjamin, governance Author Keywords: Benjamin, citizenship, governance, safe streets, sustainable community
Asserting sexual (dis)interest
Sexual assertiveness encompasses skills in refusing unwanted sexual situations and bringing about wanted sexual situations. Measures of sexual assertiveness typically assess both refusal and initiation aspects, yet there is a dearth of research examining these skills in relation to one another. The present study examined the relationship between these skillsets in women, exploring predictors of each. Initiation and refusal assertiveness were moderately correlated. Additionally, the relationship between them was not entirely explained by general assertiveness, indicating that there is something unique to assertiveness in the sexual context. Committed relationship context and erotophilic disposition specifically predicted initiation assertiveness. Less endorsement of the sexual double standard and fewer approach motivations for engaging in unwanted sex specifically predicted refusal assertiveness. Few differences emerged in predictors of assertiveness types when comparing sexual orientation groups, yet non-heterosexual women reported slightly lower levels of refusal assertiveness. Implications for sexual education, therapy, and future research are discussed. Author Keywords: sexual assertiveness, sexual autonomy, sexual compliance, sexual double standard, sexual satisfaction, sexual self-disclosure
Assessing Brook Trout (Salvelinus fontinalis) Seasonal Occupancy in Haliburton County, ON Using Environmental DNA
Brook trout (Salvelinus fontinalis) are declining across Ontario in both numbers and distribution, prompting concern for their future. Here, conventional, emerging, and predictive tools were combined to document brook trout occupation across seasons using streams in Haliburton County, ON as model systems. By using the Ontario Ministry of Natural Resources and Forestry’s (OMNRFs) Aquatic Ecosystem Classification (AEC) system variables with environmental DNA (eDNA) sampling and backpack electrofishing, my research supports the development of species occupancy models (SOMs) and eDNA as tools to document brook trout occurrence. To do this, eDNA sampling was validated in Canadian Shield stream environments by comparison with single-pass backpack electrofishing before seasonally sampling two river systems across their main channel and tributaries to assess occupancy. Streams were classified as potential high, moderate, and low-quality brook trout habitats using indicator variables within the AEC and sampled seasonally with eDNA to quantify occupancy and relate it to habitat potential at the county scale. Results showed eDNA to be an effective tool for monitoring fish across Canadian Shield landscapes and that brook trout occupancy varied seasonally within and across watersheds, suggesting that habitat and fish management strategies need to consider seasonal movement and spatial connectivity. Using these tools will enable biologists to efficiently predict and document brook trout occurrences and habitat use across the landscape.

Assessing Canada Lynx Dispersal Across an Elevation Barrier
Mountain ranges are often thought to restrict movement of wildlife, yet previous studies evaluating the role of the Rocky Mountains as a dispersal barrier for Canada lynx (Lynx canadensis) have been contradictory. Our study uses neutral microsatellite loci to evaluate the role of the Rocky Mountains as a barrier to gene flow for lynx. Although lynx exhibited low genetic differentiation, we detected a limited effect of the mountains. Furthermore, we inferred the role played by landscape variables in gene flow (genetic differentiation predicted by landscape resistance). Limited gene flow most strongly related to resistance from physical factors (low snow cover and elevation), rather than other topographic and ecological factors (high terrain roughness, low forest cover, low habitat suitability, and geographic distance). Structural connectivity was a relatively poor predictor of functional connectivity. Overall, the Rockies represent an area of reasonably high functional connectivity for lynx, with limited resistance to gene flow.

Assessing Connectivity of Protected Area Networks and the Role of Private Lands in the United States
Forestalling biodiversity loss through the establishment of protected areas is a universally accepted conservation strategy, yet despite established guidelines for protected area coverage and placement, much of the world is currently failing to meet its commitments to conservation planning and landscape protection. Calls for the United States to protect more land usually focus on the need for strategic selection of land parcels to bolster protected area coverage and network functionality, but to date there lacks focused research on either the role of private protected areas in conservation planning or the factors affecting individual protected area selection and importance. We determined gaps in conservation planning in the contiguous United States by analyzing the connectivity of protected area networks by state, and assessing the importance of private protected areas in improving linkages in protected area connectivity. We found that all states had low coverage from protected areas (average <8.4% of total land mass), and especially private protected areas (average <1.1% of total land mass), and that the overall contribution of such areas to protected area network connectivity also was low. Terrain ruggedness was identified as the main factor affecting the current location of protected areas, and that protected area spatial layout is a primary influence on landscape connectivity. We conclude that establishment of private protected areas could offer a viable conservation tool for increasing protected area coverage and connectivity, but that current efforts are inadequate to either adequately link existing protected areas or to meet established land protection guidelines.

Assessing Emotion Processing Deficits in Youth
It is well-established that alexithymia in adulthood is a critical risk factor for numerous negative mental health and well-being outcomes. Although this area of research has begun to receive interest in earlier developmental stages, significant methodological limitations have been noted with current measures of alexithymia for adolescence. As such, the aim of the current thesis was to provide empirical evidence on the psychometric strength of a new adolescent measure of alexithymia, the Toronto Alexithymia Scale – Adolescent Version (TAS-A). Study 1 examined the construct validity of the TAS-A in relation to self and informant reported emotional intelligence (EI), while study 2 examined the predictive validity of the TAS-A in relation to adolescent problematic gambling and academic achievement. Adolescents completed self-reports of alexithymia, EI, and gambling behaviour, parents completed informant reports regarding their child’s EI, and academic records were obtained. Confirmatory factor analyses revealed significant relationships between adolescent alexithymia, and self and informant reported EI, indicating significant overlap in constructs. Adolescent alexithymia was also shown to be a significant predictor of problematic gambling and academic achievement; however, some interesting gender differences were observed (a pattern of results reported consistently in the adult alexithymia literature). Results are discussed in terms of methodological and clinical implications during the vulnerable developmental transition of adolescence. Author Keywords: adolescence, alexithymia, psychometrics
Assessing Measured and Perceived Risks to Drinking Water Sources
Microcontaminants originating from wastewater effluent and run-off from agricultural lands may be present in the sources of drinking water for rural and Indigenous communities in mixed-use watersheds. In this study, a convergent parallel mixed-methods design was applied to assess measured and perceived risks of contamination in the sources of drinking water for two communities; the Six Nations of the Grand River community in Ontario and the community of Soufriere in St. Lucia, West Indies. The overall goal of the project was to assess how measured and perceived risks of exposure to chemical and biological contaminants in drinking water sources could inform water management strategies for the communities. Quantitative data obtained from the analysis of water samples collected indicated that the highest levels and occurrence of fecal bacteria were found in the Soufriere watershed while the highest concentrations and occurrence of pesticides were found in the Grand River watershed. In the Grand River watershed, conventional treatment of water followed by activated carbon filtration and UV disinfection removed fecal bacteria and also removed many chemical microcontaminants with efficiencies as high as 98%. Data from both watersheds indicated that there was a strong positive correlation between the levels of caffeine and sucralose (i.e. indicators of wastewater contamination) in water samples and the levels of either Total Coliforms or fecal bacteria of human origin. Human health risk assessments of individual pesticides and pesticide mixtures performed by applying a hazard quotient (HQ) and hazard index (HI) model, respectively indicated that there were no apparent risks to human health from those microcontaminants. Qualitative data obtained from face-to-face interviews with water managers and health professionals working in the two communities, which were collected and analysed concurrently but independently, illustrated that there were cross-cultural similarities and differences in factors influencing the perceptions of risks associated with the sources of drinking water. These perceptions of risks were mainly influenced by factors such as heuristics or informal and informal reasoning, cognitive-affective factors, social-political institutions and cultural factors. These factors may have also influenced water managers and health professionals, as they often recommended more “soft” strategies for managing water resources in the communities. Key words: pesticides, fecal bacteria, microcontaminants, POCIS, measured risks, perceived risks, water management, First Nations, Grand River, Soufriere, St. Lucia Author Keywords: fecal bacteria, measured risks, microcontaminants, perceived risks, POCIS, water management
Assessing Molecular and Ecological Differentiation in Wild Carnivores
Wild populations are notoriously difficult to study due to confounding stochastic variables. This thesis tackles two components of investigating wild populations. The first examines the use of niche modeling to quantify macro-scale predator-prey relationships in canid populations across eastern North America, while the second examines range-wide molecular structure in Canada lynx. The goal of the first chapter is to quantify niche characteristics in a Canis hybrid zone of C. lupus, C. lycaon, and C. latrans to better understand the ecological differentiation of these species, and to assess the impacts of incorporating biotic interactions into species distribution models. The goal of the second chapter is to determine if DNA methylation, an epigenetic marker that modifies the structure of DNA, can be used to differentiate populations, and might be a signature of local adaptation. Our results indicated that canids across the hybrid zone in eastern North America exhibit low levels of genetic and ecological differentiation, and that the importance of biotic interactions are largely lost at large spatial scales. We also identified cryptic structure in methylation patterns in Canada lynx populations, which suggest signatures of local adaptation, and indicate the utility of DNA methylation as a marker for investigating adaptive divergence.

Assessing Quality of Life for the Urban Inhabitants of Classical Angkor, Cambodia (c. 802-1432 CE)
This thesis examines the interrelationship of urban planning and population health at the site of Angkor (c. 802-1432 CE), the capital city of the Classical Khmer state, now found within modern-day Cambodia. The inhabitants of Angkor developed a settlement strategy that relied on the dispersal of water management features, rice fields, temples and residential areas, to best utilize the spread-out environmental resources of the surrounding monsoon-forest climate. Thus, the main question to be answered by this thesis is this: did the city-planning practice of dispersed, low-density agrarian urbanism promote resilience against the disease hazards associated with tropical environments? To answer this question, methods involved creating assessing environmental and socio-cultural factors which habituated the urban inhabitants of Angkor’s relationship to disease hazards. The results of this assessment demonstrate that it was not until the last stages of Angkor’s urban development, when non-farming members of the population were concentrated into the “core” area of temples within city, that the city’s inhabitants’ vulnerability to infectious disease increased. As the city took a more compact settlement form, it was not as environmentally compatible as the earlier dispersed pattern. Significantly, archaeological case studies such as this can illustrate the long-term development and end-result of urban planning to deal with disease hazards, both in terms of everyday occurrences, as well as during crisis events, which has important implications for contemporary research on environmental disasters today.
