Introduction: An injury surveillance system was piloted in 2011 to monitor injuries in Canadian Forces. This evaluation of the key system attributes examined system performance. Methods: A retrospective chart review, a coding reliability study, a completeness of forms study and a key informant interview. Results: Sensitivity was 0.36 (95% CI: 0.28, 0.46). The system was missing patients over age 35. Kappa coefficients over 0.80 demonstrated good agreement. Completeness of forms study demonstrated high percentages of response for most questions and lower rates for questions related to using protective equipment, and consent for information sharing. Interviews proved acceptability to stakeholders, usefulness for identifying clusters and trends, simple and complete data collection, and flexibility. Conclusion: The injury surveillance system had good potential for several reasons: data collection did not require additional work in clinics; the system was well accepted and partially proved usefulness and timeliness in identifying unusual injury events.

Withdrawal of life support therapy involves controlled removal of life support modalities including artificial respiration and circulation with intent to provide a comfortable death. Withdrawal of life support therapy is necessary prior to procedures such as organ donation after cardio-circulatory death, but remains poorly explored in current literature. To enhance the current evidence, we conducted a thorough structured review, an observational study, and a qualitative comparison of components comprising withdrawal of life support therapy in both donor and non-donor patient groups. At all stages, we considered how results impacted donation after cardio-circulatory death. Withdrawal of life support therapy processes vary between countries, hospitals, practitioners, and patients. Variability in practice impacts care and outcomes for both donor and non-donor patients. Improved definitions and consensus about the process of withdrawal of life support therapy may improve patient care, success of organ donation after cardio-circulatory death, and uptake of donation protocols.

The prevalence of male-centric pornography has been attributed to accepted (heteronormative) notions of gender specific sexual arousal, with men being characterized as visually stimulated and women naturally more aurally and emotionally receptive (cf. Christensen 1990, Faust 1980, Soble 2002). It has been argued that “if women reject the freedom to enjoy pornography and even male cheesecake, it must be because – no matter what permissions society gives us – women do not want it” (Abramson and Pinkerton 1995: 184). As women are not imagined as the intended recipients of these materials, this study was interested in how women connect their use of sexually explicit materials to their sexual biographies in the on-going process of (re)presenting their sexual identities. I wanted to not only explore what women conceptualize as sexually explicit materials and how they make sense of what they are seeing, but how and why these materials are used, the meanings attributed to these materials and the pleasures derived from them. To this end, 26 women between the ages of 25-35 were interviewed, either individually or as part of a focus group. A theoretical analytic, which bridged interactionist accounts of meaning-making and Foucauldian accounts of discourse, discipline and docile bodies, was articulated to account for how pornographic spectatorship is created, maintained and regulated. Regulation and resistance were situated within broader understandings of sexual scripts and governmentality, focusing on the construction (meaning-making) and deconstruction (resistance) of understandings of mainstream/malestream pornography. This research resulted in two interesting outcomes: (a) the redefinition of ‘gaze’ to account for active female spectatorship, as described by the women who participated in this study; and (b) discussion surrounding the ‘ethical use’ of pornographic materials, conceptualized via a governmentality lens. For the women who participated in this study, engaging with sexually explicit materials was not a passive experience. The narratives elicited demonstrate that these women did not merely absorb pornographic representations unquestioningly; they interrogated them, both subconsciously and consciously, brought new meanings to them and understood them through a decidedly female gaze – their own. These findings suggest a disruption to the assumption of female sexual passivity reverberated throughout patriarchal society.

The quest for sustainable development has always involved the complex task of reconciling the need for socio-economic development with public health and environmental protection. This challenge has often emerged in the trade and environment debate but has most recently been evident in international trade in used electrical and electronic equipment (UEEE). While international trade in UEEE provides means for socio-economic development in the developing world, it also serves as a conduit for transboundary dumping of e-waste in the developing world giving rise to serious health and environmental concerns. This research investigates the socio-economic as well as health and environmental impacts of international trade in UEEE in two developing countries – Nigeria and Ghana. The research identifies a major loophole in the existing international legal framework as the primary factor responsible for e-waste dumping in the developing world. This loophole relates to the absence of a legal framework for differentiating between functional UEEE and junk e-waste. This has resulted in both functional UEEE and junk e-waste being concurrently shipped to the developing world as “used electrical and electronic equipment”. The research proposes two policy frameworks for addressing this problem. On the part of developing countries, the research proposes a trade policy framework crafted in line with WTO rules. This framework will entail the development of an international certification system which will serve to differentiate functional used electronics from junk e-waste. While the former may be eligible for import, the research proposes an import ban on the latter. On the part of developed countries, the research proposes the development of a policy framework which regulates the toxic and hazardous substances that go into the production of electrical and electronic equipment as well as enhance their reusability and recyclability at end-of-life. The framework should take into consideration the entire life cycle of the products from the design stage to end-of-life. The research argues that the implementation of this design framework will go a long way in reducing the health and environmental impacts of such equipment when subsequently shipped to the developing world at end-of-life.

Isocyanates have a broad spectrum of uses and they are used in the production of many products including polyurethane polymers, coatings, adhesives, paints and foams. While isocyanates are widely studied and well represented in the literature, nitrogen substituted isocyanates are quite rare. Amino and imino-isocyanates are examples of nitrogen substituted isocyanates. Previous work within the group studied the reactivity of these intermediates in the alkene aminocarbonylation reaction, and used hydrazones and hydrazides as precursors of nitrogen substituted isocyanates. From there, a second reaction pathway was studied. This involved the reactivity of hydrazones with nucleophiles to develop a simple exchange reaction. In this work, the substitution reactivity involving imino-isocyanates will be presented. This will include the scope of nucleophiles and hydrazones as well as a discussion on the formation of the imino-isocyanates. This reactivity allows for the facile formation of a variety of hydrazones with the flexibility to start from common hydrazone precursors.

When compared to traditional concrete, steel fibre reinforced concrete (SFRC) shows several enhancements in performance, including improved tensile resistance, toughness and ductility. One potential application for SFRC is in columns where the provision of steel fibres can improve performance under axial and lateral loads. The use of SFRC can also allow for partial replacement of transverse reinforcement required by modern seismic codes. To improve workability, self-consolidating concrete (SCC) can be combined with steel fibres, leading to highly workable SFRC suitable for structural applications. Recent advances in material science have also led to the development of ultra-high performance fibre reinforced concretes (UHPFRC), a material which exhibits very high compressive strength, enhanced post-cracking resistance and high damage tolerance. In heavily loaded ground-story columns, the use of UHPFRC can allow for reduced column sections. This thesis presents the results from a comprehensive research program conducted to study the axial behaviour of columns constructed with highly workable SFRC and UHPFRC. As part of the experimental program, twenty-three full-scale columns were tested under pure axial compressive loading. In the case of the SFRC columns, columns having rectangular section and constructed with SCC and steel fibres were tested, with variables including fibre content and spacing of transverse reinforcement. The results confirm that use of fibres results in improved column behaviour due to enhancements in core confinement and cover behaviour. Furthermore, the results demonstrate that the provision of steel fibres in columns can allow for partial replacement of transverse reinforcement required by modern codes. The analytical investigation indicates that confinement models proposed by other researchers for traditional RC and SFRC can predict the response of columns constructed with SCC and highly workable SFRC. In the case of the UHPFRC columns, variables included configuration and spacing of transverse reinforcement. The results demonstrate that the use of appropriate detailing in UHPFRC columns can result in suitable ductility. Furthermore, the results demonstrate the improved damage tolerance of UHPFRC when compared to traditional high-strength concrete. The analytical investigation demonstrates the need for development of confinement models specific for UHPFRC.

Abstract The number of internationally educated nurses (IENs) in Ontario is growing. Given the predicted nursing shortage due to an aging nursing workforce and a short supply of nursing graduates, this trend will probably continue as international recruitment to meet nursing demands in Canada continues. Current Canadian research that examines IENs’ experience as they integrate into their workplaces is scarce. With an increasingly diverse Canadian and patient population due to rising immigration trends, a workforce that addresses the needs of the diverse patient population is valuable. Therefore an in-depth understanding of IENs’ experience, their contribution to nursing practice, and their distinct role in promoting health care access to Canada’s diverse population is necessary. A qualitative study using descriptive phenomenology was used to explore the integration experiences of eleven IENs within the Ontario, Canada health care system. Interviews were conducted to examine their experience of integrating into Canadian work settings. Thematic analysis informed by a descriptive phenomenological lens was used to uncover the essence of the IEN’s integration experience. The findings are categorized into five major themes including: Relationship with colleagues; Professional knowledge and experience; Organizational practices and work environment; Cross-cultural and linguistic competence; and IENs as an asset to nursing and patient care. These findings were nested within an overarching theme of resilience and an intrinsic motivation to establish their credibility as competent nurses. These findings highlight IENs’ unique integration experiences, and contribute to Canadian literature in the field, especially in terms of an understanding of IENs’ unique contribution to nursing in Canada. Implications and recommendations for nursing with regards to practice, education, research, and administration are presented.

New immigrants to Canada are identified as a vulnerable population in mental health and, as a result, organizations are signaling the need to enhance their mental health supports. The research uses focus groups and questions based on the messaging of a Canadian school mental health program to understand how new immigrant mothers interpret and develop key aspects of their mental health literacy and how they attain parent empowerment. A thematic assessment of the knowledge, interpretation, action and decision-making of the study participants (n=7), all recent immigrants to Canada and mothers of high school students, shows that new immigrant mothers are prepared to follow a path towards mental health literacy. At the same time, however, there are barriers that can block progression towards mental health literacy for this audience. These findings are supported by three umbrella themes: the first main theme “home as haven” espouses maternal roles in mental health maintenance such as protector and communicator, the second main theme “knowledge versus suspicions of mental health and mental illness” represents informed views and support of mental illness and myths and illusions of mental illness, and the third main theme, “additional barriers to mental health literacy” includes the hardships of immigration and fear of knowledge. The study concludes that new immigrant mothers appreciate the importance of fostering mental health understanding and discussion with their children at the same time that they encounter obstacles to the advancement of their mental health literacy. This study is relevant to the field of communication in that it demonstrates the experience of new immigrant mothers as a secondary audience in mental health programming. As the caregivers of their children, they are in position to enforce the messages and health maintenance behaviours of a school-based mental health program aimed at adolescents.

This thesis examines mothers’ risk perceptions and protective actions as they relate to their children’s environmental health. Children are more exposed and vulnerable than adults to environmental hazards, which have been found to be associated with numerous immediate and long-term negative health outcomes, due to physiological and behavioural factors. Despite the responsibility mothers typically bear as primary caregivers to their children, little is known about how they perceive and negotiate these risks in their day-to-day lives. To better understand mothers’ perceptions and associated protective actions across socioeconomic and geographic contexts, a mixed-method approach was employed involving a quantitative telephone survey (n=606) in Peel Region and Ottawa Public Health Units and qualitative face-to-face interviews (n=15) in Ottawa. Risk perceptions were influenced by income and perceived control, and concerns ranged from chemicals in household products to outdoor air pollution. There was a commonly reported perception that mothers should automatically become more concerned and take protective actions once they have children. When financial or other barriers prevented mothers from taking direct action to reduce risks, such as switching to safer products or changing food habits, they may have relied on emotion-focused coping techniques to reduce feelings of concern, including choosing to ignore risk information. Mothers’ information sources were examined to understand how risk information is best internalized; while the most common source of environmental health risk information was the Internet, many mothers expressed their mistrust in it and would have preferred to receive information directly from healthcare providers. This research contributes to the understanding of risk perception and protective action in a largely understudied population and the findings have practical implications for risk management and communication strategies targeting pregnant women and new mothers.

A Portuguese clay (BRN) from the North East city of Bragança was collected and characterized in terms of health treatment and applied towards the preparation of nanocomposites with Polylactide (PLA). The silt-clay fraction of BRN is mainly composed of smectite with less illite, kaolinite and other minerals. The physicochemical properties are applicable for the topical applications and are mainly influenced by smectite. With the hazardous elements present, further bioavailability tests should be conducted. PLA nanocomposites with BRN and Wyoming montmorillonite SWy-2 (MMT) were respectively prepared through the solution casting method with ultrasonic stirring and using cetyltrimethylammonium bromide (CTAB) as the surfactant. The X-ray diffraction patterns show the exfoliated structures in most samples. Thermal gravimetric analysis reveals the increased thermal stability of the nanocomposites. The complexes were also characterized by nitrogen adsorption, infrared analysis and nuclear magnetic resonance for comparing the differences between BRN and MMT.
