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.

Student's Bell Tower
The university newspaper is a vital aspect of the university public, as it provides a platform for students to voice their opinions on topics pertaining to the culture of their university and gives students critical information about what is happening on campus. This thesis uses the University of Regina’s The Carillon as a case study to evaluate how university newspapers interact with and influence their publics. In Chapter One, I detail the history of The Carillon, and how the radical atmosphere of the 1960s influenced the newspaper’s growth. In Chapter Two, I explore how The Carillon uses facets of digitality—such as their website, multimedia, and social media—to increase its readership. The chapter examines how these digital platforms reach The Carillon’s publics more efficiently, but still adhere to the traditions established by the newspaper from its inception. Finally, in Chapter Three, I assess the success of university newspapers which have transitioned to a strictly digital presence. For this assessment, I use the University of Alberta’s The Gateway and the University of Prince Edward Island’s The Cadre as case studies, and argue that The Carillon can learn from these digital newspapers to become more effective in using digital media to reach its student public. Altogether, this study of university newspapers offers a guide on how to maintain a balance between materiality and digitality, while also preserving the university newspaper’s legacy and traditions.

Historic Magnetogram Digitization
The conversion of historical analog images to time series data was performed by using deconvolution for pre-processing, followed by the use of custom built digitization algorithms. These algorithms have been developed to be user friendly with the objective of aiding in the creation of a data set from decades of mechanical observations collected from the Agincourt and Toronto geomagnetic observatories beginning in the 1840s. The created algorithms follow a structure which begins with pre-processing followed by tracing and pattern detection. Each digitized magnetogram was then visually inspected, and the algorithm performance verified to ensure accuracy, and to allow the data to later be connected to create a long-running time-series. Author Keywords: Magnetograms
Social Anxiety and Emotional Competence
Prior research has examined social anxiety, emotional competence (EC) and life adjustment (i.e., loneliness and life satisfaction) using cross-sectional designs, although there is limited information on their association over time. The present study examined the impact of social anxiety on life adjustment and assessed if EC could mediate this relationship from young to middle adulthood. University students (N = 283) completed self-report measures at two time points: in first year university and 15 years later. The results accord with previous research demonstrating the stability and slight decrease of social anxiety over time. Social anxiety in young adulthood was a robust predictor of loneliness in middle adulthood, and a weak predictor of life dissatisfaction for men. Mediation analyses revealed that social anxiety was indirectly associated with interpersonal adjustment via EC, especially the intrapersonal EC domain. Social anxiety requires early intervention and EC may help to prevent later social anxiety and maladjustment. Author Keywords: emotional intelligence, life adjustment, social anxiety
It's All in Your Head
The Continuity Hypothesis states that dreams reflect waking day cognition and experiences, which reflect one’s mental health status. As such, dreams are, by extension, cognitions that occur during sleep. To date, Cognitive Behavioural Therapy (CBT) is deemed the most efficacious method of social anxiety treatment by working with cognitions. The current study utilized both CBT and The Storytelling Method (TSM) of dream interpretation, whose methodology is based on CBT; CBT works with waking cognitions and TSM works with sleep cognition. This study examined the effectiveness in decreasing social anxiety symptoms with TSM and comparing its efficacy to a traditional CBT technique. Undergraduate psychology students (N = 36) completed a daily journal of either the TSM or CBT format for two weeks. Participants completed self-report measures of social anxiety, state-anxiety, and depression before and after practicing either method. TSM did not significantly decrease levels of social anxiety, state-anxiety, or depression, whereas CBT significantly decreased only social anxiety levels. Dream content reflecting waking day anxiety and depression did not decrease over time, coinciding with the findings that students did not experience a decrease in their waking day life, supporting the Continuity Hypothesis. Findings suggest anxiety and depression to be very stable in this sample. Future research should explore interventions that are clinician-guided, in a group setting, or, occur over a longer period of time.

Investigating the regional variation in frequencies of the invasive hybrid cattail, Typha × glauca
Interspecific hybridization rates can vary depending on genomic compatibilities between progenitors, while subsequent hybrid spread can vary depending on hybrid performance and habitat availability for hybrid establishment and persistence. As a result, hybridization rates and hybrid frequencies can vary across regions of parental sympatry. In areas around the Laurentian Great Lakes, Typha × glauca is an invasive plant hybrid of native Typha latifolia and introduced Typha angustifolia. In areas of parental sympatry in Atlantic Canada and outside of North America, T. × glauca has been reported as either rare or non-existent. I investigated whether the low frequencies of hybrids documented in Nova Scotia, Atlantic Canada, are influenced by reproductive barriers that prevent hybrid formation or environmental factors (salinity) that reduce hybrid performance. I identified an abundance of hybrids in the Annapolis Valley (inland) and a scarcity of hybrids in coastal wetlands through preliminary site surveys throughout Nova Scotia. In Annapolis Valley populations, flowering times of progenitor species overlapped, indicating that asynchronous flowering times do not limit hybrid formation in this region. Viable progeny were created from interspecific crosses of T. latifolia and T. angustifolia from Nova Scotia, indicating that there are no genomic barriers to fertilization and germination of hybrid seeds. Typha × glauca germination in high salinity was significantly lower than that of T. latifolia, but there was no difference at lower salinities. Therefore, while germination of hybrid seeds may be impeded in the coastal wetlands where salinity is high, inland sites have lower salinity and thus an environment conducive to hybrid germination. However, I found that once established as seedlings, hybrids appear to have greater performance over T. latifolia across all salinities through higher ramet production. Moreover, I found that T. latifolia sourced from Ontario had reduced germination and lower survivorship in high salinities compared to T. latifolia sourced from Nova Scotia, which could indicate local adaptation by T. latifolia to increased salinity. These findings underline that interactions between environment and local progenitor lineages can influence the viability and the consequent distribution and abundance of hybrids. This, in turn, can help explain why hybrids demonstrate invasiveness in some areas of parental sympatry but remain largely absent from other areas.

Ethnoarchaeology in the Traditional Villages of Bagan, Myanmar
This thesis investigates the current composition of traditional settlements located in and around the remains of the ancient, walled and moated, regal-ritual epicenter of Bagan, Myanmar. This study also provides some suggestions as to strategies that may be employed by future settlement archaeology projects in the region. To achieve the aims of this study, an ethnoarchaeological approach was employed at ten village sites located on the Bagan plain: Thè Pyin Taw, Thè Shwe Hlaing, Zee Oo, Kon Sin Kyi, Kon Tan Gyi, Minnanthu, Hpauck Sein Pin, Thah Tay Kan, East Pwa Saw, and West Pwa Saw. The data obtained from these villages, compounds, and houses is used to generate a version of the average Bagan village, compound (i.e., house lot), and house. The model Bagan village, compound, and house are in turn used to provide the basis for suggestions to be used in future settlement archaeology projects.

knight and his horse
This thesis examines the social impact of horses on French elites between 1150 and 1300. Using courtly literature, a veterinary treatise, manuscript illuminations, archeological studies, material artefacts, and account books, it explores the place of horses in elite society—practical and symbolic—and assesses the social costs of elite use and ownership of horses. While horses served practical functions for elites, their use and investment in horses clearly went far beyond practicality, since elites used horses recreationally and sought prestigious horses and highly decorated equipment. Their owners used horses in displays of power, status, and wealth, as well as in displays of conspicuous consumption and the performance of gender roles. The social display associated with horses was integrally tied to the ideology and performance of chivalry. This study examines the broader use of horses by elites to understand their place in the elite culture of the High Middle Ages.

Anthropogenic microfibres in background natural environments in Ireland
Microfibres, which are threadlike particles < 5 mm, are the most common type of microplastic reported in the environment. However, few studies have focused on their abundance in background natural environments. This study assessed the abundance of microfibres in rainfall samples (from four precipitation monitoring stations) and across three headwater lake catchments that were in remote, undeveloped areas, away from anthropogenic disturbance and anthropogenic emission sources (i.e., sites were background natural environments). Anthropogenic microfibres were observed in all samples using visual identification methods, with Raman spectroscopy confirming the presence of polyester film and synthetic pigments, e.g., indigo and hostasol green. The estimated annual average atmospheric deposition of microfibres was ~28,800 mf m-2. Meteorological variables, e.g., rain, wind direction, and relative humidity were correlated with the abundance of microfibres. The average abundance of microfibres in headwater lake catchments was 24 mf g-1 in moss, 0.70 mf m-3 in surface trawl, 9,690 mf m-3 in subsurface, 910 mf kg-1 in lake sediment and 576 mf kg-1 in lakeshore sediment.

An Emergent Model of the Return to Learn Process for Adolescents with Prolonged Concussion
Current literature on concussion management focuses primarily on the return to physical activity, while the return to learn process is less clearly understood. This knowledge gap is particularly problematic for adolescents, whose primary responsibility is academics. The present study sought to develop a more in-depth understanding of the return to learn process through the perspectives of adolescents who had sustained a concussion and their parents in in-person, semi-structured interviews. A substantive grounded theory of the return to learn process for adolescents that emerged from the data is provided. The basic model is consistent with many speculative, non-empirically based concussion management protocols, but extends these models by emphasizing the central role of parents in managing their child’s recovery process, highlighting the importance of role fulfillment within the concussion management network, and identifying the impact of the adolescent’s capacity and readiness for help-seeking. The results also highlight the vulnerability of concussed adolescents to losing their support structure as they move through key school transitions. Implications for educators, medical professionals, parents, and adolescents in the return to learn process are also discussed.

When He Reigns, It Pours
This thesis examines the symbolic meaning and significance that the elite attached to water in ancient Bagan. Through the use of ethnoarchaeological, epigraphic, archaeological, and iconographic data, this study examines the role of water as part of rituals performed by the royal court and the ways in which the royalty of Bagan, in particular King Kyansittha, negotiated, appropriated and disseminated water symbolism to fulfill his interests. Data indicates that the symbolic and religious meaning of water was intricately attached to Buddhist concepts of fertility, wisdom, creativity, and protective powers. Evidence suggests that the royalty employed different techniques to appropriate and disseminate water ritualization, including the performance of water rituals that were closely attached to kingship, power, and ruler legitimacy, the promotion of an alliance with creatures capable of increasing rains and fertility, and the use of analogies that compared the properties of water with the virtues of the king.

Cytokinins in nematodes
To investigate cytokinins (CKs) in nematodes, CK profiles of a free-living Caenorhabditis elegans and a plant parasitic Heterodera glycines (soybean cyst nematode, SCN) were determined at the egg and larval stages. SCN had higher total CK level than C. elegans; however, CKs in SCN were mostly inactive precursors, whereas C. elegans had more bioactive forms. This is the first study to show that methylthiols are present in nematodes and may affect plant infection. In infectious SCN larvae, methylthiol levels were much higher than in eggs or C. elegans larvae. Furthermore, The CK profiles of SCN-susceptible and resistant Glycine max cultivars at three developmental stages revealed that, regardless of the resistance level, SCN infection caused an increase in root CKs. One resistant cultivar, Pion 93Y05, showed significantly high levels of bioactive N6-isopentenyladenine (iP) in the non-infected roots which indicated a potential role of CKs in soybean resistance to SCN. Author Keywords: Cytokinins, HPLC-MS/MS, Nematode, SCN resistance, Soybean
