Cemeteries and Hunter-Gatherer Land-Use Patterns
The principle aim of this thesis is to evaluate the applicability of the Goldstein/Kelly hypothesis, which proposes that hunter-gatherer cemeteries emerge as a product of resource competition, and function to confirm and maintain ancestral ties to critical resources. My evaluation centres on a case study of the earliest known cemeteries of the middle Trent Valley, Ontario. To determine whether these predictions are true, I investigated the ecological context of local wetland-based foraging, and undertook a locational analysis to determine if the placement of cemeteries correlates with environmental characteristics that reflect the presence of valuable resources that are unique to these locations. The analysis reveals that ancient cemeteries in the middle Trent Valley were located near seasonal riparian wetlands, possibly to secure wild rice and the variety of fauna it attracts. Through the integration of paleoecological, archaeological, and ethnographic information for the region, this research finds support for the Goldstein/Kelly hypothesis.

Tool-use and near-tool effects
After active tool-use visual stimuli near a tool are processed more quickly and accurately than those farther away from a tool. Can these near-tool effects be modulated by training demands? To investigate this we asked the participants to complete a tool training task followed by a cross-modal interference task. During the training task the participants performed quick and accurate pointing movements to reach a strict or moderate criterion. The results indicated that the strict group made faster movements than the moderate group. During the cross-modal interference task visual distractors were presented along handheld tools in conjunction with vibrotactile stimuli on the hand. No significant compatibility effects were found for visual distractors near the hand or tool tip, and no consistent group differences were found. Our findings demonstrate the importance of using a novel tool during training, and that virtual stimuli may not be effective to elicit near-tool effects. Author Keywords: bimodal neurons, cross-modal interference, near-tool effects, tool training, training demands
Late Epigravettian Resource Exploitation in the Southern Pre-Alpine Region
This study examines the foraging strategies employed by Late Epigravettian occupants at Riparo Tagliente, Italy. The study sample is composed of highly fragmented macrofaunal remains recovered from a single stratigraphic layer (layer 617) located at the cave border in the southern portion of the site. Models derived from foraging theory, chiefly the Central Place Forager Prey Choice Model, are applied to interpret the pattern of faunal exploitation. Red deer (Cervus elaphus) is the most commonly identified species in the sample, followed by roe deer (Capreolus capreolus) and wild boar (Sus scrofa). The faunal analysis suggests that the site occupants focused their foraging efforts in lower–altitude resource patches at short travel distances. The distribution and composition of the sample indicates that bone may have been used as a fuel source in this area. Author Keywords: Archaeozoology, Foraging Theory, Taphonomy, Upper Paleolithic
"I like big books"
The purpose of this study was to determine whether students at the Royal Military College (RMC) preferred electronic or print texts, their reasoning for this preference, and whether preference was related to student characteristics. Students (N=139) in a core course were provided with both formats. Due to a limited number of e-text users, statistical analyses of most variables were not possible. Instead, qualitative responses were analyzed to gain insight into student preferences. Students reported on the benefits and concerns of using each format. Their discussion of the benefits to the e-text and concerns about the print text were related to the level of convenience of each format. When considering the benefits of print and drawbacks of e-texts, students explained how these features could impact their reading experience. This study provides qualitative support for the continued use of print texts. Although they frequently use various forms of technology in the classroom, students are reluctant to study using electronic devices and feel their reading experience is best with print.

Investigating Ecological Niche Differentiation Among Wild Candids Experiencing Hybridization in Eastern North America
Currently there are large areas of the North American landscape that are occupied by Canis spp. hybrids of several varieties, leading to the logical question as to the genetic structure and ecological function of Canis populations across the continent, and to what extent hybrids reflect contemporary landscapes. This study illustrated patterns of niche differentiation between parental canid species and their hybrids using individual high quality genetic profile and species distribution models to support the intermediate phenotype hypothesis. In general, hybrids demonstrated an intermediate habitat suitability compared to its parental species, across most environmental variables used. A similar trend was observed in the niche metric analysis, where we found that hybrids exhibit intermediate niche breadth, with eastern coyotes and eastern wolves exhibiting the broader and narrower niche, respectively. Our results demonstrate that the intermediate phenotype hypothesis is supported even at a large scale and when involving highly mobile large mammal species. Author Keywords: canid, ecological niche modelling, hybridization, intermediate phenotype, microsatellite genotype, niche differentiation
Sexual consent
How one identifies their nonconsensual sexual experiences (NSE) and cognitively integrates the experience into their sexual schemas may affect how individuals perceive and negotiate sexual consent. Previous research has demonstrated that both the method of quantifying NSEs and the labels used to describe NSEs yield different results in psychosexual outcomes associated with NSEs. The current study assessed differences in subjectively and behaviourally quantified NSEs, as well as the role of cognitive and affective appraisals of sexuality and sexual interactions, on sexual consent attitudes. While behaviourally measured NSE history did not significantly influence sexual consent attitudes, the subjective identification of NSEs with various labels did influence attitudes toward sexual consent. Cognitive appraisals of rape and affective appraisals of sexuality also significantly predicted sexual consent attitudes. Implications for future research and NSE prevention are discussed.

Childhood Precursors of Adult Trait Incompleteness
Previous research has suggested that childhood sensory sensitivity may predict adult obsessive compulsive (OC) behaviours. To date, however, research has not addressed how the separate dimensions – harm avoidance and incompleteness - may influence this relationship or why it exists. The current study used a retrospective design to test a) if sensory sensitivity in childhood predicts trait incompleteness in adulthood, as well as b) if emotion regulation variables mediate this relationship. Questionnaires pertaining to OC dimensions and childhood anxieties were completed independently by 172 undergraduate participants and their primary childhood caregiver. Results showed a linear relationship between sensory sensitivity in childhood and incompleteness in adults. Emotion regulation variables failed to mediate this relationship, although a trend for mediation was present. Additionally, exploratory analysis found perfectionism in childhood to be a predictor of trait incompleteness but not harm avoidance, whereas physical anxieties predicted harm avoidance and not incompleteness. Results are discussed in the context of clinical and theoretical implications.

Situating Copper Bells in Prehispanic Southwest Societies
This thesis examines the spatial, temporal, and contextual distribution of copper bells in the Greater Southwest region and how they are situated in archaeological literature. To date, 672 copper bells have been found in at least 113 different Southwestern sites dating from ca. A.D. 900-1450, though there is no archaeological evidence for metallurgical activities in the area at this time. The origin of copper bells has been assumed to be West Mexico, a region known for its metallurgical traditions and whose inhabitants produced copious amounts of similar bells. Various lists of copper bells discovered have been compiled over the years, but little consideration has been given to the role these artifacts may have played in Southwestern societies. Copper bells are frequently labelled as prestige goods in archaeological literature, a term which fails to account for their significant depositional variation. By updating the database of known Southwestern copper bells, it becomes possible to examine these contextual distributions in greater detail. It is concluded that the prestige goods model is not suitable for Southwestern copper bells in many cases, and that alternative frameworks such as inalienable possessions are a better fit for these artifacts. Author Keywords: Archaeology, copper bells, inalienable possesions, interaction, U.S. Southwest
Comparing Two Tablet-Based Visuomotor Tasks to Standard Laboratory Versions
The assessment of visuomotor function can provide important information about neurological status. Several visuomotor tasks exist for testing in the laboratory, although attempts to make these tests portable to allow quick and reliable assessment have been limited. We developed an assessment tool using two laboratory visuomotor tests as a tablet application: the double-step task, and an interception task. Performance was assessed by measuring the participants’ ability to reach toward unpredictably moving targets in each task. Response patterns were compared across equipment types to determine if participants were responding similarly to the moving targets in the standard laboratory and the tablet version of the tasks. On the double-step task, participants adjusted to the displaced target adequately in both the lab and tablet versions. On the interception task, participants intercepted non-accelerating targets, and performed worse on accelerating targets in both versions of the task. These findings suggest that the tablet version of these tasks assesses similar visuomotor processing as the respective laboratory version.

Rights, Resources, and Resistance
The development of pan-Indigenous political organizations in northeastern Alberta in the context of oil and gas development during the 1970s created disparate effects on Indigenous communities in the region. Resistance to assimilation policies led the Indian Association of Alberta to transform itself into a unified voice that represented Aboriginal and treaty rights in the late 1960s; however, the organization lost legitimacy following the divergence of goals between influential Indigenous leaders, Harold Cardinal and Joseph Dion. Tripartite agreements began to unfold between the federal and provincial governments, the oil and gas industry, and individual local leadership; environmental degradation spread throughout the landscape. Some communities benefitted financially whereas other communities, like Lubicon Lake Nation, received little compensation and felt the full force of industrial contamination of their traditional territories. Without the support of pan-Indigenous political organizations, Lubicon Lake developed an individual response that was successful in gaining international attention to their conditions. Author Keywords: 1970s, Indigenous politics, Lubicon Lake Nation, northern Alberta, political economy, tar sands
Exploring and Evaluating Personal, Cultural and Social Food Needs and the Role of a Community Freezer among Inuit in Hopedale, Nunatsiavut
This thesis sought to explore and evaluate perceptions of food needs and the role of a community freezer in addressing those needs, among Inuit in Hopedale, Nunatsiavut (Northern Labrador). Research was carried out through an exploratory sequential mixed-methods design. Phase 1 employed qualitative interviews with community members in Hopedale to explore the perceptions of food needs from an Inuit perspective. Results from Phase 1 identified a series personal, physical, cultural, and social food needs that informed the development of a series of questions that were integrated into a community-wide survey that was implemented in Phase 2. Results from Phase 2 identified a series of cultural, household and individual characteristics that significantly impact perceived ability to meet needs among community members in Hopedale. Findings from this research contribute to our understanding of food needs, and may potentially influence estimates of levels of needs that are protected in Inuit land claims, and inform the development or improvement of community methods for food support.

Effect of Listing a Stock on the S&P 500 Index on the Stock’s Volatility
This paper investigates the effect of listing a stock on the S&P 500 Index on the stock’s volatility, using various econometrics models: GARCH and EGARCH. The study mainly addresses three issues; firstly, it analyzes stock volatility in two sub-periods, secondly, it determines whether the announcement can account for the fluctuations in the price of the stock, and finally, it investigates the change in the stock’s variance. After isolating the effects of external and industry shock by using the returns on the S&P 500 Index as a proxy, the author finds evidence of structural change in the volatility of stocks after that stock is added to the index. Additionally, the existence of a dominant symmetric effect, which captures the response of volatility to news, indicate that following the onset of including the stock on the index, information flowing into the market increased. However, the rate at which old news is captured in price falls. The empirical evidence also suggests that on average a stocks variance falls and that the announcement to list a stock on the index has little effect on the stock’s price. Author Keywords: EGARCH, GARCH, S&P 500 Index, Symmetric Effect, Volatility
