Through An Intersectionality Lens: Service Provider Views On The Sexual Health Needs Of Racialized Lgbtq Youth In Toronto, Shanshan Yan

Theses and Dissertations (Comprehensive)

This thesis explores the needs and gaps in knowledge and service delivery in sexual health for racialized LGBTQ youth living in Toronto, Canada from the perspective of service providers. Through a grounded theory approach, data were analysed using an intersectionality lens with the intention that the complex identities of the youth be considered. The findings of this study shed light on the barriers that operate at the micro (ie. personal), meso (ie. community) and macro (ie. societal) levels that affect the sexual health outcomes of racialized LGBTQ youth. Key findings from this study point to: 1) the need to closely …

Characterizing Dsrna Production In Virus-Infected Fish Cells, Amal Brek Aloufi

Theses and Dissertations (Comprehensive)

Viral dsRNA is produced by almost all viruses sometime during their replicative cycle. These viral nucleic acids are potent inducers of both innate and adaptive immune responses, and are therefore considered important immuno-modulators. Previous studies have shown that viruses produce dsRNA when replicating in mammalian cells; however, to date no one has demonstrated viral dsRNA production in virus infected fish cells. Therefore, the goal of this study is to investigate dsRNA production by fish viruses in fish cells, verifying production and performing initial characterization of the dsRNA molecules being produced. Three different rainbow trout cell lines were used in this …

Gait Initiation Mechanics In Concussed Varsity Athletes, Adam Harper

Theses and Dissertations (Comprehensive)

Concussions are a common and potentially serious injury that affects athletes across multiple sports. More than ever concussions are now at the forefront of sport-related research.

Current research indicates that in a cohort of Canadian junior hockey players examined during the 2009-2010 season showed a rate of concussion at 36.5% of all athletic injuries (Echlin et al., 2010). This rate of concussion injury indicates that proper evaluations and examination tools are key to successful management of concussions. The objective of this study was to determine whether a functional task such as gait initiation is able to quantify stability difference following …

Response To Mental Health Calls: The Frontline Perspectives Of Police Officers, Communicators And Administrators, Sarah C. Dougall

Theses and Dissertations (Comprehensive)

Abstract

OBJECTIVES: The purpose of this study was to examine the lived experiences of frontline police personnel of a mid-sized police service in Southern Ontario. As the prevalence of mental illness increases, so do the calls for assistance to police services. Police officers often find themselves on the frontline and are often the first responders to mental health calls when an individual is in crisis (Wells & Schafer, 2006). With the majority of current research being quantitative in nature, this qualitative study allowed the voice of frontline police personnel to be heard in order to provide a complete picture of …

Quantifying Rooftop Solar Power For The City Of Waterloo, Ontario, Shawn W. Macdonald

Theses and Dissertations (Comprehensive)

Climate change, pollution, and energy security are driving a worldwide transition away from traditional fossil fuel generated electricity. As the world moves away from fossil fuels and towards renewable energy, electricity generated from photovoltaic solar panels is one of the most promising and capable technologies available today. Arguably the most suitable location to generate this electricity is at the source of consumption. Placing solar panels on unused rooftop space can subsidize the electricity demand that that building requires. This research quantifies the amount of electricity that can be generated within the City of Waterloo, Ontario. Using Natural Resources Canada data, …

Vocabulary And Reading Comprehension Intervention: A Focus On Students In The Late Elementary Grades, Melissa L. Dol

Theses and Dissertations (Comprehensive)

Literacy skills are key to success in school, career, and everyday life. Despite school curricula being strongly focused on literacy development (Ministry of Education, 2006), many children continue to fall behind the expected literacy skill levels for their grade (Education Quality and Accountability Office, 2012a, 2012b; National Center for Education Statistics, 2011). The present study evaluated a literacy intervention, Better Reading for School Success (BRSS), accompanied by a parent/guardian literacy workshop and weekly tips regarding how parents and/or guardians can promote literacy skill development at home. The BRSS was also evaluated as a subsection of family literacy afterschool programs, ‘Get …

Children's Cognitive Processing Of Abuse As Described In Investigative Interviews., Kayleen A. Willemsen, Kim P. Roberts

Theses and Dissertations (Comprehensive)

A great deal of research has examined ways in which investigative interviewers can elicit accurate information from children. More recently, research has studied children’s own thoughts or comprehension of abuse, and how these types of statements relate to disclosure, others’ perceptions of child witnesses, and psychological trauma. However, little research has investigated multiple types of children’s thoughts about abuse as they occur in an actual investigative interview. The current study examined seven types of statements children made about their abuse in a sample of 86 transcripts of investigative interviews conducted by Child Protective Services and a police department in a …

The Lived Experiences Of Adult Siblings Of Individuals With Asd, Brianne Redquest

Theses and Dissertations (Comprehensive)

Autism Spectrum Disorders (ASD) are the most prevalent neurological and severe developmental disorder affecting 1 in 88 Canadians, reflecting a 78% increase over the last 6 years (Autism Speaks Canada, 2013). ASD is a lifelong disorder which requires a tremendous amount of support and caregiving from family members. As a result, siblings may have unique experiences associated with having a sibling with ASD. As such, the purpose of this study was to examine the lived experiences of adult siblings of individuals with ASD. The study employed a qualitative methodology, more specifically phenomenology (Patton, 2002). One-on-one semi-structured interviews were conducted with …

An Exploratory Examination Of Families Engaged In An Adventure Running Kids Program, Heather Isnor

Theses and Dissertations (Comprehensive)

Academics and practitioners have only just begun to delve into the health benefits of outdoor activities in the last few years. In general, the forested settings of these activities have been documented to decrease stress levels, increase recovery rates from disease, and lessen the symptoms of mental illnesses (Kuo & Faber Taylor, 2004). It is believed that the natural environment acts as a setting where humans can engage in physical activity, aesthetic experiences, and social interactions that, in turn, release stress and lead to improved well-being (Bird, 2012). Currently, however, children are experiencing limited exposure to nature and which has …

Improving Preschoolers' Mathematical Performance: The Nature Of Spatial Input By Early Childhood Educators, Joanna Zambrzycka

Theses and Dissertations (Comprehensive)

Early spatial abilities are related to a number of positive academic outcomes such as success in geometry and chemistry domains in later adulthood (Delgado & Prieto, 2004; Stieff, 2007). Further, more advanced spatial abilities in early adolescence predicts engagement and success in science, technology, engineering, and mathematics (STEM) occupations in later adulthood (Shea, Lubinski, & Benbow, 2001). There is a wealth of research that links spatial abilities to overall mathematics achievement in both adults (e.g., Casey, Nuttall, Pezaris, & Benbow, 1995) and children (e.g., Holmes, Adams, & Hamilton, 2008).

Adult input positively impacts children’s subsequent spatial and mathematical development. Parental …

Effects Of A Heart Rate Variability Biofeedback Intervention On Athletes’ Psychological Responses Following Injury, Andrew S. Rollo Mr.

Theses and Dissertations (Comprehensive)

The purpose of this study was to evaluate the effectiveness of heart rate variability biofeedback (HRV BFB), a form of psychophysiological skills intervention, to improve athletes’ psychological response following an injury. Further, to examine the effects of HRV BFB on self-efficacy, perceived stress and anxiety, pain management, and the psychological responses of injured athletes. HRV BFB effects on athletes’ physiological indices including HRV, HR, and respiration rate were also assessed. Participants were 32 athletes who had sustained a moderate to severe musculoskeletal sports injury, ranging in age from 18 to 36 years (M_age = 20.82, SD = 3.41). …

Laterality Across The Lifespan: The Effects Of Task Complexity, Nicole Williams

Theses and Dissertations (Comprehensive)

The current study aimed to build on the work of Gooderham & Bryden (2013) by comparing the effects of task complexity on hand selection across the lifespan. It was hypothesized that the increasing complexity of a task would override a biomechanically efficient movement such that participants would use only the preferred hand to complete the task. It was also hypothesized that older adults would perform similarly to young children with respect to switch points in space. Four age groups of participants (3-7 year olds, 8-12 year olds, 18-25 year olds and adults over 70 years) completed the newly designed Hand …

Polish Or Work? Four Women Novelists And The Professionalization Of Accomplishment, 1796-1814, Ada Sharpe

Theses and Dissertations (Comprehensive)

Polish or Work? Four Women Novelists and the Professionalization of Accomplishment, 1796-1814 examines the ways in which cultural models of accomplished, industrious femininity find expression in four novels written by women during the Romantic period: Amelia Opie’s The Father and Daughter (1801), Mary Brunton’s Self-Control (1811), Ann Radcliffe’s The Italian (1796), and Frances Burney’s The Wanderer (1814). This dissertation reads accomplishment as a pervasive and familiar cultural practice that writers use to interrogate domestic ideology and middle-class women’s position in commercial society within the space of popular fiction. I focus, specifically, on instances in which the genteel heroine turns privately …

Quantifying Cognitive Function In Concussed Athletes Before And After Acute Exercise Using A Choice Reaction Time Task, Stephanie A. Ramautar M.Sc., Michael E. Cinelli Ph.D.

Theses and Dissertations (Comprehensive)

Following a concussion, cognitive deficits have been shown to last longer than symptom resolution. Currently clinicians rely heavily on symptom emergence following the fundamental exercises of the return to play (RTP) protocol, which may leave athletes at risk of returning to play too early if cognitive deficits have not been detected. The purpose of this study was to assess the effects of exercise on choice reaction time (CRT) both at rest and following an acute exercise in 3 populations: non-concussed (NC), recently concussed (RC), and post-concussion syndrome (PCS) individuals. A CRT task in the form of an iPad application measured …

The Transient Collaboration Model: Theory Building, Structural Formation, And Operationalization, Adrian C. Tan

Theses and Dissertations (Comprehensive)

This thesis seeks to describe the Transient Collaboration Model as a business model, its underlying theoretical principles, its empirical evidence, and its types of possible collaboration structures. The research seeks to determine how companies may build sustained competitive advantages through the structural design of their collaboration associations as a strategic option. Companies' ability to retain long-term competitive advantages is limited in more unpredictable environments. Companies could not afford to internally build and hold all the possible varieties and quantities of resources and capabilities to build future competitive advantages. Collaboration can provide companies with access to multiple partners with diverse resources …

Integrated Spatial Analysis Of Volunteered Geographic Information, Haydn Lawrence

Theses and Dissertations (Comprehensive)

Volunteered Geographic Information (VGI) is becoming a pervasive form of data within geographic academic research. VGI offers a relatively new form of data, one with both potential as a sensitive way to collect information about the world, and challenges associated with unknown and heterogeneous data quality. The lack of sampling control, variable expertise in data collection and handling, and limited control over data sources are significant research challenges. In this thesis, data quality of VGI is tackled as a general composite measure based on coverage of the dataset, the evenness in the density of data, and the relative evenness in …

Juror Perceptions Of Eyewitness Identification Evidence, Timothy G. Wykes

Theses and Dissertations (Comprehensive)

Jurors rely on eyewitness testimony in deciding a defendant’s guilt or innocence. Archival analyses of hundreds of post-conviction DNA exonerations have identified eyewitness misidentification as the highest individual factor contributing to wrongful convictions (Innocence Project, 2014). Internationally, criminal justice systems have employed procedural safeguards (PSs) to educate juries on factors affecting eyewitness identification accuracy. Two such safeguards include the introduction of eyewitness expert testimony during trial proceedings and the reading of cautionary instructions by a presiding judge. In an independent factorial design, this research sought to examine the effects of a model judicial caution drafted by the Ontario Judicial Council …

Effects Of Salinity And Dissolved Organic Matter On Cu Toxicity To Americamysis Bahia In Estuarine Environments, Rabia Nasir

Theses and Dissertations (Comprehensive)

As salinity increases the geochemical speciation of Cu is altered as a result of organic/inorganic complexation/competition. Such salinity changes may further challenge the osmoregulatory capabilities of euryhaline organisms. This chemical-biological interaction complicates the understanding of the impacts of Cu in estuarine waters. Dissolved organic matter (DOM) has been widely established to be an important modifier of Cu toxicity in freshwaters however its effectiveness in modulating Cu toxicity across the range of salinities that occur in estuarine conditions has not been studied in a systematic manner. Site to site differences in DOM quality with respect to the potential for toxicity mitigation …

Physical Fitness Characteristics Of An Active Firefighter Population Serving An Urban Area, Michael R. Antolini

Theses and Dissertations (Comprehensive)

Firefighters require a high level of physical fitness in order to meet the demands of their profession. While physical fitness testing is required to join the department, firefighters are not subject to further formal exercise testing throughout the duration of their careers. Active, career firefighters were tested on a variety of physical fitness measures related to body composition, strength, power, and endurance over three testing sessions. 49 firefighters (40.5 ± 8.3 yr, 89.5 ± 13.0 kg, 27.8 ± 3.6 kg/m2) were found to have a resting heart rate of 57.7 ± 8.2 bpm, blood pressure of 121.5 ± 11.9/71.5 ± …

Relative Equilibria Of Isosceles Triatomic Molecules In Classical Approximation, Damaris Miriam Mckinley

Theses and Dissertations (Comprehensive)

In this thesis we study relative equilibria of di-atomic and isosceles tri-atomic molecules in classical approximations with repulsive-attractive interaction. For di-atomic systems we retrieve well-known results. The main contribution consists of the study of the existence and stability of relative equilibria in a three-atom system formed by two identical atoms of mass $m$ and a third of mass $m_3$, constrained in an isosceles configuration at all times.

Given the shape of the binary potential only, we discuss the existence of equilibria and relative equilibria. We represent the results in the form of energy-momentum diagrams. We find that fixing the masses …

Predicting Motivation, Exercise Behavior And The Reciprocal Relationship With Obesity Perceptions In College Students, Kylee Jo Heston

Theses and Dissertations

Obesity is an increasing problem worldwide, often described as an epidemic. Approximately 70% of men and women nationwide are overweight and/or obese, with roughly 34% meeting criteria for obesity. Women are increasing obesity rates faster than men and more women than men are currently obese nationwide and worldwide. Obesity leads to numerous physical, psychological, and social consequences and often a poor quality of life. Women are at risk for increased health complications, and college in particular has been associated with weight gain. Improper energy balance is a significant contributor. Achieving adequate exercise each week has been proven effective in obesity …

Seven-Year Responses Of Trees To Experimental Hurricane Effects In A Tropical Rainforest, Puerto Rico, Jess K. Zimmerman, James Aaron Hogan, Aaron B. Shiels, John E. Bithorn, Samuel Matta Carmona, Nicholas Brokaw

United States Department of Agriculture Wildlife Services: Staff Publications

We experimentally manipulated key components of severe hurricane disturbance, canopy openness and detritus deposition, to determine the independent and interactive effects of these components on tree recruitment, forest structure, and diversity in a wet tropical forest in the Luquillo Experimental Forest, Puerto Rico. Canopy openness was increased by trimming branches, and we manipulated debris by adding or subtracting the trimmed materials to the trimming treatments, in a 2 X 2 factorial design replicated in three blocks. Tree (stems > 1 cm diameter at breast height) responses were measured during the 9-year study, which included at least 1 year of pre-manipulation monitoring. …

Narrowing The Gap Between Rights And Resources: Finding A Role For Law Students In Court-Annexed Resource Centers, Faith Mullen

Scholarly Articles

This article relates the experience of law students from The Catholic University of America providing assistance in the Small Claims Resource Center during the past eight years. During this time, the District of Columbia Bar Pro Bono Program has played a pivotal role in the development and the ongoing success of court-annexed resource centers in the District of Columbia. They have recruited law firms and legal services providers (including law school clinics) to staff the resource centers, sought changes in the rules of professional responsibility, and developed intake forms and model pleadings. Their steady oversight, provided by knowledgeable and resourceful …

Bridging The Gaps In Property Theory, Adam J. Macleod

Scholarly Articles

Though several others can rightly be said to have done as much, no one has done more to rehabilitate the idea of property as a meaningful normative concept than James Penner and Henry Smith. That the two of them have edited a collection together is a substantial reason to read it. That the collection contains contributions from many of the best property theorists is another. The introduction to the book sets the ambitious goal of identifying what needs explaining in the ‘broad space that lies between’ the philosophy of property and scholarship about particular legal doctrines. For anyone interested in …

Quantitative, Qualitative, And Collaborative Methods: Approaching Indigenous Ecological Knowledge Heterogeneity, Jeremy Spoon

Anthropology Faculty Publications and Presentations

I discuss the use of quantitative, qualitative, and collaborative methods to document and operationalize Indigenous ecological knowledge, using case studies from the Nepalese Himalaya and Great Basin. Both case studies applied results to natural and cultural resource management and interpretation for the public. These approaches attempt to reposition the interview subjects to serve as active contributors to the research and its outcomes. I argue that the study of any body of Indigenous knowledge requires a context-specific methodology and mutually agreed upon processes and outcomes. In the Nepalese Himalaya, I utilized linked quantitative and qualitative methods to understand how tourism influenced …
