Factors Influencing Influenza Vaccination Rates Among Rural Ontario Paramedics, Tonya A. Leduc

Theses and Dissertations (Comprehensive)

Introduction. Influenza vaccination rates have traditionally been very low among healthcare workers (HCWs) however; very few studies have examined vaccination rates andmotivators among paramedics.

Objectives. The Health Belief Model (HBM) (Rosenstock,1974) was used as a guideline in this study to better understand the motivators and barriers to flu vaccination among rural Ontario paramedics. This group represents a considerable proportion of the HCW community, yet it has been virtually omitted from previous research.

Methods. Through the use of self-report questionnaires, and using the HBM as a guideline, a graphical representation of the decision-making process regarding flu vaccination was generated. The sample …

The Nature Of Resident Participation In The Exploration And Installation Stages Of The Implementation Of A Community-Based Primary Prevention Program For Young Children, Jessica S. Noble Ms.

Theses and Dissertations (Comprehensive)

Resident participation is a vital factor and key prerequisite to the planning, development and implementation of community-driven projects. Early implementation evaluations, especially during the planning stages of project development, are critical to ensuring effective resident participation. Understanding the nature of resident participation, including the activities involved, facilitators, barriers, and outcomes of engagement, is essential for laying the foundation for program success and sustainability. This study was an implementation evaluation of a small community-based initiated project that examined resident participation, varying by degrees of involvement throughout the early stages of implementation. The sample (N = 11) consisted of three service-providers, …

Scalar Short-Term Memory, Tyler D. Bancroft

Theses and Dissertations (Comprehensive)

The location of the brain’s working and short-term memory (WM/STM) “system” is unclear. The existence of a dedicated WM/STM system is itself under debate. Recently, it has been proposed that WM/STM storage relies not on a dedicated system in prefrontal cortex, but rather that it is an emergent function of interaction between attentional and representational systems (e.g., sensory cortex) in the brain. However, mnemonic representations of very simple stimuli have repeatedly been shown to exist in frontal cortex. In this manuscript, I use computational and behavioural methods to demonstrate similarities between the representations of different types of very simple stimuli …

More Than Stone And Iron: Indigenous History And Incarceration In Canada, 1834-1996, Seth Adema

Theses and Dissertations (Comprehensive)

This dissertation examines Indigenous (First Nation, Métis, and Inuit) history as played out in Canadian prisons. It argues that in the prison, processes of colonialism, decolonization, and neocolonialism took place simultaneously. In the nineteenth century, the prison was built as part of a network of colonial institutions and polices. It was imagined, designed, and built by representatives of the Canadian state alongside other colonial institutions, drawing on similar intellectual traditions. It maintains the imprint of this colonial origin. Prisons also became arenas for Indigenous cultural exchange and cultural creation, which in most cases subverted the logic of the prison. This …

Let's Talk About (Consensual) Sex!, Eleanor M. Mcgrath

Theses and Dissertations (Comprehensive)

Legal, moral, and health-related issues around sexual consent have become prominent in the media in recent years. The public debate surrounding these news stories indicates a large discrepancy in people’s understanding of sexual consent and its legal implications. Motivated by the fact that university students are sexually victimized at rates exceeding the general population, this study explores factors that influence knowledge of legal aspects of sexual consent and confidence in using such knowledge of students/alumni, under 30 years old, from two southern Ontario universities. This quantitative study used an online survey design, and is grounded in a heuristic paradigm, with …

Examining Quality Indicator Rates For Older Home Care Clients With Dual Sensory Impairment (Dsi) And Exploring The Heterogeneity Within Dsi., Jacob G S Davidson, Dawn M. Guthrie

Theses and Dissertations (Comprehensive)

Older adults with impairments in both hearing and vision, called dual sensory impairment (DSI), are at an increased risk of negative health outcomes such as impaired communication and difficulties with mobility. It is unknown whether DSI is associated with potential quality of care issues. This study used a set of home care quality indicators (HCQIs) to examine potential quality issues in older clients (65+) with DSI. Further, it looked to explore how HCQI rates differed based on the geographic region of care and whether the client’s level of hearing and vision impairment was related to certain HCQIs. The HCQIs were …

The Role Of Organic Matter In The Surface Chemistry Of Arsenic Compounds On Iron−(Oxyhydr)Oxides Studied By Atr-Ftir, Arthur Situm

Theses and Dissertations (Comprehensive)

The interaction of organic matter with the interfaces of active soil components such as iron oxides is ubiquitous within soil environments. The presence of organics at these interfaces may have implications for other soil constituents whose mobility is controlled by their ability to bind to active soil components. Most of the studies performed to date which look at these interactions are bulk/batch studies performed ex-situ. Attenuated total internal reflectance Fourier transform infrared spectroscopy (ATR-FTIR) was utilized within this work to study interactions between select model organics (citrate, oxalate and pyrocatechol) and iron−(oxyhydr)oxides, as well as their effect on the surface …

Epr Paradox, Nonlocality, And Entanglement In Multi-Qubit Systems, Raja Emlik

Theses and Dissertations (Comprehensive)

Bell inequalities were formulated by John Bell to test the possible violation of local realistic theories by quantum mechanical systems. It was shown that entangled quantu-m states of multiple particles violate various Bell’s inequalities. This proved that quan-tum mechanics allows correlations between spatially separated systems that have no classical analogue. The main focus of this work is to investigate genuine multiqubit non-locality in families of entangled 3 and 4-qubit pure states by studying a Bell-type inequality that is violated only if all qubits are non-locally correlated. We numerically study the relationship between entanglement and violation of the Svetlichny Bell-type inequality. …

Comparing The Regio- And Enantioselectivity Of Inverting Versus Retaining Epoxide Hydrolases, Mark A. Aliwalas

Theses and Dissertations (Comprehensive)

Epoxide hydrolases (EHs) are enzymes that catalyze the ring opening of an epoxide, yielding a vicinal diol. This exciting class of enzymes is often associated with natural product and small molecule biosynthesis. One interesting class of natural products that epoxide hydrolases are involved in the biosynthesis of is the enediynes. Previously, 5 enediyne-associated epoxide hydrolases have been characterized, revealing an inverting-versus-retaining paradigm for enediyne epoxide hydrolases. The work described herein sets the table for future studies involving the probing of the α/β-epoxide hydrolase mechanism for styrene oxide. Kinetic and regioselectivity characterization of the enediyne-associated CynF and SghF has determined that …

The Effects Of Manipulated Somatosensory Input On Simulated Falls During Walking, Sarah Mitchell-Ewart

Theses and Dissertations (Comprehensive)

Previous research has demonstrated that there is a distinct relationship between aging and instability. The somatosensory system plays a significant role in balance control in conjunction with vision and the vestibular system (Qiu et al., 2012). Evidence has shown that manipulation of the mechanoreceptors on the plantar surface of the foot has a direct effect on balance control. By manipulating these receptors with hypothermic anesthesia and vibration, researchers are capable of simulating the effect of sensory modification on healthy individuals, in order to understand the role that plantar-surface sensation has in adapting to perturbation during gait (Perry et al., 2001; …

The Effect Of Menstrual Cycle Phase On Appetite-Regulating Hormones, Logan Townsend

Theses and Dissertations (Comprehensive)

Background: Obesity rates are higher among females than males potentially due to changing food intake across the menstrual cycle. Food intake is partially regulated by circulating appetite-regulating hormones that can be influenced by the menstrual hormones estradiol and progesterone. Purpose: Examine whether changes in female sex hormones across the menstrual cycle are related to appetite-regulating hormones. Methods: 8 healthy young females were tested during the follicular, ovulatory, and luteal phases; phases were confirmed by fasting plasma hormone concentrations. Blood samples were taken after an overnight fast, as well as 30, 60, and 90 min post-prandially to test the concentrations of …

Investigative Inadequacies Or Investigative Corruption? Exploring The Role Of Police Misconduct Within Canadian Wrongful Conviction Cases, Michelle L. Lovegrove

Theses and Dissertations (Comprehensive)

The phenomenon of wrongful convictions has begun to attract the attention of the public and scholars alike within the past few decades. However, despite this recent fixation the issue of wrongful convictions is not new, as research on the subject dates back to 1932 with the work of Edwin Borchard. Most of the research on the subject of wrongful convictions has focused largely on identifying the factors that contribute to these injustices. For the most part academics are in agreement when it comes to the causes of wrongful convictions, which include, eyewitness misidentification, false confessions, police & prosecutor misconduct, use …

Characterization Of A Phosphonate-Specific Cytidylyltransferase, Kissa Batul

Theses and Dissertations (Comprehensive)

Antibiotic resistance is a major global health concern that requires new therapeutic approaches. Furthermore, a lack of narrow spectrum antibiotics on the market produces unintended consequences with respect to changes in our microbial make up. Phosphonates are reduced versions of phosphates that possess a C-P bond which is more resistant to enzymatic and chemical degradation. The role of phosphonate containing macromolecules (e.g. cell surface polysaccharides) remains enigmatic, however their presence suggests that they may confer an advantage. The biosynthesis of phosphonate-containing macromolecules is unknown, but a pathway is proposed involving aLicC type cytidylyltransferase-catalyzed conjugation to a phosphonate followed by a …

Investigating Balance-Enhancing Effects Of Midsole Hardness And Thickness For Older Adult Footwear, Elizabeth Mcleod

Theses and Dissertations (Comprehensive)

Falls among older adults (OA) is becoming increasingly more prevalent. One third of OA fall each year; of those fallers, 20-30 percent endure various injuries ─ fatal and nonfatal. Older women are especially at risk and are twice as likely than men to sustain a fatal injury following a fall, including severe hip fractures. This study aimed to explore and confirm balance-enhancing evidence for thin and hard midsoles/insoles through an experimental environment with a single data collection session. It was hypothesized that balance would improve while wearing hard insoles in combination with a hard midsole when compared to standard insole …

Equi-Biaxial Fatigue Testing Of Epm Utilising Bubble Inflation, Mark Johnson, Niall Murphy, Ray Ekins, John Hanley, Stephen Jerrams

Articles

This paper describes an equi-biaxial tension fatigue test system which utilises the bubble inflation method to subject elastomers to equi-biaxial fatigue loading between user-defined limits of pressure, volume, stretch ratio or stress. The test system integrates a hydraulic inflation system, a high speed vision system and a control system. The high-speed vision system allows the stretch ratio and stress acting on the test specimen to be evaluated in real-time during testing. This in turn allows either stretch ratio or stress to be used as a direct control limit. In this research, constant maximum engineering stress control tests have been carried …

Comparison Of Secondhand Smoke Exposure In Minority And Non-Minority Children With Asthma, David A. Fedele, Erin M. Tooley

Arts & Sciences Faculty Publications

Objective—Determine if secondhand smoke exposure (SHSE) is related to asthma-related functional morbidity by examining racial/ethnic differences in Non-Latino White (NLW), African American, and Latino families and whether racial/ethnic SHSE differences across families persist when accounting for smoking factors.

Methods—Participants were 305 caregiver smokers of children with asthma. Two passive dosimeters measured SHS: one in the home and one worn by the child.

Results—Higher SHSE was related to greater asthma-related functional morbidity. African Americans had higher levels of home SHSE than Latinos (p = .003) or NLWs (p = .021). SHSE as assessed by the child …

When Partisans And Minorities Interact: Interpersonal Contact, Partisanship And Public Opinion Preferences On Immigration Policy, Shanna Pearson-Merkowitz, Alexandra Filindra, Joshua J. Dyck

Political Science Faculty Publications

Objective: Many studies investigating contact theory have suggested that contact effects are not universal but rather conditional. In this article, we test one form of conditional contact effects. Our approach posits that contact with out-groups produces support for pro-minority public policies only when in-group members are not subject to contrary messages from co-partisans.

Methods: We use data from an original survey to test this theory in the immigration policy domain.

Results: We find strong confirmatory evidence that the emergence of contact effects on support for a path to citizenship for undocumented immigrants is dependent on party identification. …

Compensation Or Retrenchment? The Paradox Of Immigration And Public Welfare Spending In The American States, Ping Xu

Political Science Faculty Publications

By using American state-level data from 1999 to 2008, this article explores how the recent immigrant influx has influenced public welfare spending in the American states. By integrating the race/ethnicity and globalization compensation theory, I hypothesize that immigration will increase welfare spending in states with a bleak job market and exclusive state immigrant welfare policy; in contrast, immigration will decrease welfare spending in states with a good job market and inclusive state immigrant welfare policy. Empirical tests show evidence for both hypotheses, suggesting that the applicability of general political science theories depends on a combination of state policy and economic …

Does Global Market Integration Weaken Opinion-Policy Congruence In The American States?, Bret Anderson, Brian S. Krueger, Ping Xu

Political Science Faculty Publications

Theories of economic globalization suggest that public opinion-public policy congruence should be affected by a state's degree of integration with international markets. With as much attention researchers have given to the opinion-policy linkage in the American states, it is surprising that this literature has neglected these well-known globalization frameworks. We take advantage of the wide variation in U.S. states’ integration in global markets, public policies, and political orientations of citizens, to assess whether global market integration depresses the association between citizen opinion and public policies. Using three decades of state-level data, our results suggest that high global market integration does …

Wicked Problems: How Complexity Science Helps Direct Education Responses To Preventing Violent Extremism, Lynn Davies

Journal of Strategic Security

This article draws on the insights from complexity science to outline potential strategies within education which could interrupt the spread of violent extremism. It first identifies three problems in examining extremism - definitions, causes and targets—before arguing for a focus on systems, not individual learners. Within systems, diversity is needed for emergence, and narrow, hard secularism is rejected in favor of a dynamic secularism which encourages a variety of belief systems in order to guard against polarization. The systems of education, religion, law and of terrorism itself are analyzed to identify entry points and vulnerabilities. After looking at the theories …

Integration Of New Biological And Physical Retrospective Dosimetry Methods Into Eu Emergency Response Plans – Joint Reneb And Eurados Inter-Laboratory Comparisons, Elizabeth Ainsbury, Christophe Badie, Stephen Barnard, Aidan Meade

Articles

RENEB, 'Realising the European Network of Biodosimetry and Physical Retrospective Dosimetry,' is a network for research and emergency response mutual assistance in biodosimetry within the EU. Within this extremely active network, a number of new dosimetry methods have recently been proposed or developed. There is a requirement to test and/or validate these candidate techniques and inter-comparison exercises are a well-established method for such validation.

A Novel Anthropomorphic Flow Phantom For The Quantitative Evaluation Of Prostate Dce-Mri Acquisition Techniques, Silvin Knight, Jacinta Browne, James Meaney, David Smith, Andrew Fagan

Articles

A novel anthropomorphic flow phantom device has been developed which can be used for quantitatively assessing the ability of MRI scanners to accurately measure signal / concentration time-intensity curves (CTCs) associated with dynamic contrast-enhanced (DCE) MRI. Modelling of the complex pharmacokinetics of contrast agents as they perfuse through the tumour capillary network has shown great promise for cancer diagnosis and therapy monitoring. However, clinical adoption has been hindered by methodological problems, resulting in a lack of consensus regarding the most appropriate acquisition and modelling methodology to use and a consequent wide discrepancy in published data. A heretofore overlooked source of …

Suppressed Intuitions, Large Number Coincidences, And A Mathematical Foundation For Life And Consciousness, Maurice Goodman

Articles

A brief examination of the natural sciences reveals that we are still under the influence of pre Copernican intuitions. These have only been suppresses and not supplanted. This is why we appeal to such things as large number coincidences in the hope that the mathematics, which unlike us does not suffer from naive beliefs, will lead us in the right direction. However, we need to be extremely careful as it is easy to create these coincidences and over interpret their significance. In the 1980’s work on these coincidences did lead to a mathematical formulism which seems to have relevance in …

Optimized Sliding Mode Control To Maximize Existence Region For Single-Phase Dynamic Voltage Restorers, Samet Biricik, Hasan Komurcugil

Articles

This paper presents an optimized sliding mode control (SMC) strategy to maximize existence region for single-phase dynamic voltage restorers. It is shown analytically that there exists an optimum sliding coefficient which enlarges the existence region of the sliding mode to its maximum. Also, it is pointed out that the optimum sliding coefficient improves the dynamic response. In addition, a double-band hysteresis control which ensures the switching of a transistor in the voltage source inverter during a half-cycle while it remains either on or off in the other half cycle is used to mitigate the switching frequency. The theoretical considerations and …

New Hybrid Active Power Filter For Harmonic Current Suppression And Reactive Power Compensation, Samet Biricik, Ozgur Cemal Ozerdem, Soydan Redif, Mustafa Sezai Dincer

Articles

In the case of undistorted and balanced grid voltages, low ratio shunt Active Power Filters (APFs) can give unity power factors and achieve current harmonic cancellation. However, this is not possible when source voltages are distorted and unbalanced. In this study, the cost-effective hybrid active power filter (HAPF) topology for satisfying the requirements of harmonic-current suppression and non-active power compensation for industry is presented. An effective strategy is developed to observe the effect of the placement of power capacitors and LC filters with the shunt active power filter. A new method for alleviating the negative effects of a non-ideal grid …

Three-Level Hysteresis Current Control Strategy For Three-Phase Four-Switch Shunt Active Filters, Samet Biricik, Hasan Komurcugil

Articles

In this study, a three-level hysteresis current-control (HCC) strategy is proposed for three-phase four-switch shunt active power filters. The four-switch topology which utilises four switching devices together with two series connected capacitors is able to reduce the cost, switching losses and improve the reliability of system. In this topology, when the current control of phases A and B is achieved successfully, the current control of phase C which is connected to the midpoint of the series connected capacitors is achieved automatically. The current control is achieved by using a three-level HCC strategy. An important consequence of using this control strategy …
