Field notes, member checks, and triangulation …

Estimates Of Persistent Inward Current Decline In Human Soleus Motor Units During Fatigue, Kirby Mendes

Theses and Dissertations (Comprehensive)

Fatigue is defined as any exercise induced reduction in strength or power, and can be attributed to central and peripheral components. Many central and peripheral mechanisms have been extensively studied, but few studies have looked at the changes in the intrinsic properties of motor neurons and their contribution to fatigue. Persistent inward current (PIC) is an important intrinsic property of motor neurons responsible for setting a large increase in the gain of motor output and may contribute to fatigue. Inhibitory inputs such as reciprocal inhibition (RI) have been shown to turn off PICs and reducing the gain of output. PIC …

An Exploratory Approach To Manipulating Dynamic Stability: Investigating The Role Of Visual Control During A Precision Foot Placement Task, Russell Cg Kennedy

Theses and Dissertations (Comprehensive)

ABSTRACT

Background: The visual system provides the body with an accurate sensory system; designed to gather information at a distance and acts as a feedforward control mechanism during human locomotion. By doing so, visual information contributes coordination of the head-arm-trunk (HAT) segment and modulating foot placement. The purpose of this study was to examine the effects of a constrained pathway during a complex navigational stone-stepping task on HAT segment control and how the visual system guides locomotion during a complex foot placement task.

Methods: Nine university-aged females (Mean age: 22.5 years old +/-1.75) participated in this study. Participants …

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 Tale Of Soulmates Or A Marriage Of Convenience? Tying The Knot Of Human Rights With Development And Its Goals Through Donor Programs And Projects. The Case Of The Canadian International Development Agency (Cida), Taguhi Dallakyan

Theses and Dissertations (Comprehensive)

The purpose of the dissertation was to examine whether globally agreed development goals (Millennium Development Goals (MDGs), with a specific focus on poverty reduction) were operationalized in human rights, access to justice and rule of law programs/projects of Canadian International Development Agency (CIDA) and of its executing partners. The analysis of the CIDA’s reports to Parliament and programing documents indicates that from the first years of the launch of MDGs, they were operationalized within the CIDA’s programing architecture and remained as a macro- level goal of the agency. MDGs, with the focus on poverty reduction, were treated as an ultimate …

The Effects Of External Focus Of Attention Exercise Rehabilitation On Dual Task Walking In Parkinson's Disease, Eric N. Beck

Theses and Dissertations (Comprehensive)

Parkinson’s disease impairs control of well-learned movements, and therefore, individuals with Parkinson’s disease are forced to walk with greater conscious control. This causes difficulties while walking and completing a secondary task simultaneously (dual tasking), in that distractions from conscious control of walking increase the risk of falls and injury. Although, attention-based exercise may be a potential avenue to decrease the demands associated with walking in Parkinson’s disease. For example, an external focus of attention (on manipulated objects) has been found to recruit the networks that are important for walking with little conscious control (automatic control networks). In contrast, an internal …

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 …

The 2d:4d Ratio, Handedness, And Sex Across The Age Span, Helen A M Protopapas Ms.

Theses and Dissertations (Comprehensive)

The ratio of the difference between the 2nd and 4th digits of the hand (2D:4D ratio) has been demonstrated to be an indirect indicator of prenatal testosterone levels. Prenatal testosterone has been found to play a role in brain development in utero, and thus may influence lateral asymmetries, such as handedness. Consequently, one of the aims of the current study was to examine relationships between the 2D:4D ratio, hand preference, and hand performance with the factors of sex (males and females), handedness (right handers and left handers), and age considered. A total of 104 participants were tested, 90 right handers …

The Influence Of Hip Mobility And Fatigue On Spinal Flexion And Muscle Activation In Rugby Scrum Performance, Joshua D. Clayton

Theses and Dissertations (Comprehensive)

Introduction: Rugby scrumming is a means of restarting play following a minor rule infringement that can occur up to 28 times per game. The scrum poses a significant injury risk, with more days missed due to injury per event than any other rugby activity. Rugby players also have a significantly higher rate of spine injury than the general population, perhaps due to flexion in combination with high compression forces, which has been cited as the main mechanism of injury. Flexion of the spine has also been associated with poor hip mobility and quadriceps fatigue in other athletic tasks and may …

The Influence Of Joint-Site, Limb Preference, And Physical Activity On Joint Position Sense, Amanda N. Forsyth

Theses and Dissertations (Comprehensive)

Joint position sense provides the body with information about where limb segments are relative to one another in three-dimensional space. The ability to utilize this sense is imperative for smooth, coordinated, and accurate movement in everything from activities of daily living to competitive sport (Ghez & Sainburg, 1995). Researchers currently use joint position sense as a measure of proprioceptive acuity. However, limited research has investigated the influence of potential confounding factors on proprioception. Specifically, literature on how joint-site specificity and lateral preference influence proprioception displays several incongruent findings. Therefore, the purpose of the current study was (1) to determine if …

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 …

The Effects Of A Lateral Ankle Sprain On Balance And Jumping Performance In Varsity Athletes, Jennifer Childs

Theses and Dissertations (Comprehensive)

ABSTRACT

The objective of this study was to investigate the effects of a lateral ankle sprain(s) on balance and jumping performance in varsity athletes. Clinicians often use subjective balance and jumping tasks during the rehabilitation process as criteria for returning an athlete to sport. There is a high recurrence rate of lateral ankle sprains with ongoing reports of mechanical and/or functional ankle instability often leading to chronic ankle instability. Perhaps including objective kinetic and kinematic measurements in the course of rehabilitating an ankle sprain injury may provide further information regarding the recovery process of the athlete.

Participants in this study …

Policing And The Dirty Underbelly: Understanding Narratives Of Police Deviance On Social Media Platforms, Amanda Lancia

Theses and Dissertations (Comprehensive)

Policing organizations have been quick to adopt the use of social media as a community-policing and investigative tool. However, the user-generated content on social media platforms can pose a risk to police legitimacy, police accountability, and their role as the ‘authorized knowers’. This thesis explores how social media problematizes the social problems game and how social media challenges the police as the ‘authorized knowers’. Through the analysis of two case studies - #myNYPD campaign and the Walter Scott shooting – it was found that social media users can use social media platforms to construct claims against and challenge police in …

Understanding The Influencers Of Second-Hand Apparel Shopping Behavior, Robyn Hobbs

Theses and Dissertations (Comprehensive)

Shopping for second-hand apparel is rapidly growing and has become a notable segment of the retail market. The purpose of this study is to determine what influences consumers when shopping second-hand for apparel products in-store and online. According to the existing literature, a number of key factors play significant roles for second-hand apparel shopping consumer decisions. They include: social, costs, trends and environmental influencers. Past research has not concentrated in-depth on the hedonistic and social influences of second-hand apparel shopping, financial factors, and time spent shopping for second-hand apparel. This study has observed the socio-demographic profile of second-hand shoppers, what …

An Evaluation Of The Impact Of Rent Assistance On Individuals Experiencing Chronic Homelessness In Waterloo Region, Courtney Pankratz Ms.

Theses and Dissertations (Comprehensive)

The main objective of this study was to examine the effectiveness of the addition of rent assistance to Waterloo Region’s existing housing and support services. A quasi-experimental non-equivalent comparison group design was used to compare the outcomes between two groups: (a) participants selected to receive rent assistance plus intensive support services (n = 26) and (b) participants receiving support services only (n = 25). Participants were interviewed at baseline and again six months later. It was hypothesized that participants receiving rent assistance would show significantly greater improvement on housing outcomes compared to the comparison group, including greater number of days …

Changes In Brain Water Content In The Rainbow Trout (Oncorhynchus Mykiss) And In The Goldfish (Carassius Auratus) Due To High External Ammonia Exposure, Phillip Q.H. Pham-Ho

Theses and Dissertations (Comprehensive)

In fishes, hyperammonemia may occur following feeding or exposure to abnormally high concentrations of environmental ammonia due to sewage effluents, agricultural run-off and in crowded aquaculture pens. Increased internal ammonia can result in hyperactivity, convulsions, coma and death. In mammals, it is also associated with potentially fatal brain edema, in which the accumulation of intracellular water results in swelling, increased intracranical pressure and herniation leading to death. Recently it was shown that rainbow trout (Oncorhynchus mykiss) and goldfish (Carassius auratus) experience brain swelling following exposure to high external ammonia (HEA). However, the mechanism of ammonia-induced brain …

Phosphorus Removal Using Titanium Dioxide Nanoparticles In Wastewater Treatment, Suyoung Choi Mr.

Theses and Dissertations (Comprehensive)

Due to eutrophication caused by nutrients such as phosphorus (P), local surface water near military garrisons and camps has been deteriorated for several years in the Republic of Korea. Thus, in order to remove excessive P in local fresh water, various size of titanium dioxide (TiO₂) were used.

In the first investigation, TiO₂ mixed bulk powder (particle size > 5µm) showed maximum P removal with pH dependence (higher pH shows lower P removal), that was approximately 27%. To determine adsorption isotherms, Langmuir and Freudlich models were used. The experimental data was better fit by a Langmuir model compared …

The Influence Of Freedom And Choice In Action Selection And The Valence Of Action-Outcomes On The Sense Of Agency, Zeynep Barlas Wilfrid Laurier University

Theses and Dissertations (Comprehensive)

Sense of agency (SoA) refers to the subjective experience that one is the author of their actions and the ensuing outcomes of these actions. Previous research have suggested that both sensorimotor processes and high level inferences can contribute to the SoA. In five experiments, the present thesis examined the effects of action selection processes and the valence of action-outcomes on the SoA. The majority of these experiments measured the SoA by obtaining both subjective feeling of control (FoC) judgments over the action-outcomes, and assessing the size of intentional binding. Intentional binding refers to the perceived temporal attraction between actions and …

Essays On Earnings Forecasts, Tax Expense And Ifrs Adoption, Yan Jin

Theses and Dissertations (Comprehensive)

In this dissertation, I include three essays regarding earnings forecasts, the DuPont analysis and tax expense, all using mandatory International Financial Reporting Standards (IFRS) adoption in Canada as a setting. In the first essay entitled “DuPont Analysis, Earnings Persistence and Return on Equity: Evidence from Mandatory IFRS Adoption in Canada”, I propose four new models to forecast one-year-ahead return on equity and change in return on equity based on prior research in the DuPont analysis and earnings persistence. I also examine whether the persistence of return on equity has improved since Canadian companies adopted IFRS in 2011.

In the second …

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 …

A Missing Link In The Ionoregulatory Strategy Of Larval Sea Lamprey (Petromyzon Marinus) And African Lungfish (Protopterus Annectens): A Closer Look Into The Role Of The Non-Gastric H+/K+-Atpase, Justine E. Doherty

Theses and Dissertations (Comprehensive)

Fishes living in freshwater need to actively compensate for the diffusive loss of ions and osmotic gain of water. The gill is the primary organ of ion regulation and contains an array of ion transport proteins to help maintain homeostasis. Two of the more well studied ion pumps are the Na⁺/K⁺-ATPase (NKA) and vacuolar type proton ATPase (V-ATPase). This thesis focuses on another ion pump known as the non-gastric H⁺/K⁺-ATPase (ngHKA). The ngHKA (gene: atp12a) has not been found in any of the teleost fishes, indicating loss from that lineage. In …

Professional Learning And Knowledge Transfer To Practice In Unregulated Care Provider Training In Resident-Centred Care, Sarah Pottier

Theses and Dissertations (Comprehensive)

Ongoing training for unregulated care providers (UCPs) in Ontario is required to meet the care needs of the aging population. Inconsistencies in standards and options for formal training for UCPs as well as the evolving complex needs of the aging population are factors contributing to needing training programs for UCPs in the workforce. This thesis examined the delivery and transfer of professional learning for UCP training in resident centred care. Increasing resident-centred care behaviours and knowledge were the primary aims of the training. One 128-bed long-term care home in southwestern Ontario volunteered to participate in this study while providing the …

Caring In Transition: Home Care Workers’ Experiences Of Care Relationships In Shanghai, China, Liu Hong

Theses and Dissertations (Comprehensive)

This dissertation reports a qualitative study of 23 care workers in the home care program for older people in Shanghai, China. Using grounded theory methodology, a model was developed to account for care workers’ experiences of relationships with older clients. Care workers were found to resist the image of care work as demeaning labour performed by lowly migrant workers and re-construct care as valuable work for those in need accomplished by a caring self. As a mechanism of care relationship formation, care workers engage in tuning, a dynamic process of identity negotiation that shifts in between two contrasting states: …

Exploring Institutions, Governance And Collaboration For Regional Integration Of Protected Areas In Québec, Windekind Buteau-Duitschaever Mr.

Theses and Dissertations (Comprehensive)

Abstract

The concept of protected areas (PAs) has undergone important changes. The goals and purposes of PAs are to conserve animal and plant species, landscapes and ecological processes and to provide for outdoor recreation opportunities. PA management approaches have also undergone important changes. The once widely accepted doctrines of top-down management have been replaced by management models that include a diversity of actors. In some instances, actors are now sharing governing responsibilities with state representatives while in other instances central government has transferred rights, responsibilities and authority to lower levels of government and non-state actors for the planning and management …

Mate Choice And Consequences For Consanguineous Mating In Drosophila Melanogaster, Emily S. Martin

Theses and Dissertations (Comprehensive)

The ability to discriminate between prospective mates is potentially important not only for the avoidance of unsuccessful or incompatible matings, but also for the selection of higher “quality” mates. Inbreeding, reproduction between closely related individuals, has long enjoyed the attention of biologists, and has classically been associated with fitness consequences that are primarily negative, termed “inbreeding depression”. Indeed, the costs of mating with a relative are well documented across a wide variety of species. If individuals are capable of kin recognition, it is expected that species should evolve to avoid consanguineous matings. However, a number of recent models suggest circumstances …

Sulfate-Reducing Bacteria Community Analysis: Isco/Isb Coupled Remediation, Christopher K. Bartlett

Theses and Dissertations (Comprehensive)

Improved techniques for remediating groundwater systems are required for the more than 500,000 contaminated sites in North America. Many of these sites are the legacy of historical industrial operations, inappropriate disposal practices and accidental releases. The most widely observed contaminant at many of these sites is petroleum hydrocarbons (PHCs). Recently, remediation efforts that involve the sequential application of treatment technologies have gained widespread interest. One specific sequential technology application or treatment train employs the aggressive nature of a chemical oxidation followed by bioremediation for polishing. When persulfate is used as the chemical oxidant its natural degradation by-product is sulfate, an …

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 …

An Examination Of Newcomer Integration Processes In Sport Teams: A Socialization Perspective, Alex J. Benson

Theses and Dissertations (Comprehensive)

In highly interdependent groups, the ability to swiftly and successfully integrate newcomers is an important component to maintaining functional team dynamics. The current dissertation explored how sport teams structure the nature and timing of events that newcomers are put through by implementing specific socialization tactics. In the first manuscript, a qualitative study was initiated to garner descriptive insights into the tactics that are used to socialize athletes into sport teams. Semi-structured interviews were conducted with coaches, veteran athletes, and newcomer athletes (i.e., individuals in their first year as a team member). Participant insights were thematically analyzed and compared to existing …

Strange Compositions: Chemistry And Its Occult History In Victorian Speculative Fiction, Susan Hroncek

Theses and Dissertations (Comprehensive)

This dissertation examines how depictions of chemistry in Victorian literature are influenced by concerns regarding the history of chemistry and its relationship to the occult. Among these depictions, I consider non-fiction writings of the period, such as histories of science and articles from periodicals, but I focus on novels that prominently feature chemistry, including Edward Bulwer-Lytton’s A Strange Story (1862), Robert Louis Stevenson’s Strange Case of Dr. Jekyll and Mr. Hyde (1886), George Griffith’s Olga Romanoff (1894), T. Mullet Ellis’s Zalma (1895), and Richard Marsh’s The Beetle (1897). These texts link chemistry with its origins in alchemy, the occult, and …
