Attained And Retained Employment Of Employees With Intellectual And Developmental Disabilities In Ontario, Michelle Willson

Theses and Dissertations (Comprehensive)

Employment is a critical component of health and well-being as it has been shown to increase income, reduce poverty, establish social networks, and provide a greater sense of purpose and value within society. People with disabilities have higher rates of unemployment as compared to non-disabled people and experience many barriers to employment, including stigma, attitudes towards disabilities, and perceived costs of accommodation. There is limited research that looks at what has helped to facilitate employment, particularly retained employment, for this population. Therefore, understanding factors that have served to facilitate retained employment for those with disabilities is critical in understanding how …

What Is Canada Doing? An Analysis Of Canadian University Sexual Violence Policies, Konnor Legault

Theses and Dissertations (Comprehensive)

As social awareness of the prevalence of sexual violence on university campuses has increased, it is important to understand the role of university policies in providing protection and support for the campus community and people affected by sexual violence. The purpose of this research is to analyze and compare Sexual Violence Policies (SVP) from four Canadian universities. The analysis evaluates the comprehensiveness of the policies and considers how power, and ideas of power are embedded within SVPs. Findings suggest that policies are at times comprehensive, but may be missing important information, such as including an Objectives section in the policies. …

Three Essays On The Interface Of Sales And Operations Management, Sara Babaee

Theses and Dissertations (Comprehensive)

This dissertation investigates three profit maximization models for coordinating Sales and Operations (S\&OP) management.

The first problem considers implementing a customer education strategy for the digital channel users of a multi-channel service provider. Using a customer network flow model, I investigate the effect of customer education in the digital channel on the number of users of digital and in-person channels. Further, I define a customer value metric that characterizes the optimal level of education effort. Finally, I determine conditions under which the effect of positive word-of-mouth regarding the quality of education dominates the lifetime value of customers.

The second problem …

Invisible Wounds: Assessing The Awareness Of Moral Injury Among Toronto Police, Daniel Saugh

Theses and Dissertations (Comprehensive)

Moral injury is believed to exist within the Canadian Police Services though it is difficult to recognize and is usually ignored. The research data emerging from military and first responders (i.e., police, firefighters, and EMS personnel) reveal the effects of moral injury and its implications for mental and spiritual health as it persists throughout the life and career of those affected.

This study investigates how moral injury may emerge from a potentially traumatic event(s) and/or psychological trauma and/or independent from such trauma and how moral injury may come to exist in members of the Toronto Police Service, as well as …

Dsrna Conjugated Phytoglycogen Nanoparticles As An Innate Immune Stimulant To Prevent Viral Infections In Rainbow Trout And Atlantic Salmon, Kayla Samms

Theses and Dissertations (Comprehensive)

Salmonids are one of the world’s most farmed fish species. These aquatic vertebrate species rely heavily on their innate immune responses to defend themselves against invading pathogens. Although commercial vaccines are available against some viral and bacterial pathogens affecting salmonids, their protective efficacy is variable. Using a prophylactic inducer of local and systemic innate immune responses could have significant implications in salmonid aquaculture. A potent inducer of the innate immune response in fish is double-stranded RNA (dsRNA), a molecule that all viruses make during their replicative cycle. Polyinosinic:polycytidylic acid (polyI:C) is a synthetic dsRNA commonly used to induce type I …

Binary Black Widow Optimization Algorithm For Feature Selection Problems, Ahmed Al-Saedi

Theses and Dissertations (Comprehensive)

This thesis addresses feature selection (FS) problems, which is a primary stage in data mining. FS is a significant pre-processing stage to enhance the performance of the process with regards to computation cost and accuracy to offer a better comprehension of stored data by removing the unnecessary and irrelevant features from the basic dataset. However, because of the size of the problem, FS is known to be very challenging and has been classified as an NP-hard problem. Traditional methods can only be used to solve small problems. Therefore, metaheuristic algorithms (MAs) are becoming powerful methods for addressing the FS problems. …

Working Joblessness: Young People Deploying 21st Century Skills In Post-Conflict Liberia And Sierra Leone, Frances Fortune

Theses and Dissertations (Comprehensive)

In Liberia, state economic development policies based on the resource extractive industry's short-term needs have produced too few job opportunities for young people. The development policies have failed to grow the private sector to create jobs, recognize the importance of urbanization, or expand the informal economy's contribution to employment in urban areas. As a result, young people are obliged to use their creativity and digital connections to make a living outside of the normative models of work using an organic social process of bricolage. Bricolage is a type of entrepreneurship or a form of action which can occur in resource-scare …

Constructively Deviant: Examining The Positive Employee Consequences Of Pro-Social Rule Breaking, Su Kyung (Irene) Kim

Theses and Dissertations (Comprehensive)

Conceptualized as a form of constructive deviance, pro-social rule breaking (PSRB) refers to employees’ intentional violation of a formal organizational policy, regulation, or prohibition with the primary intention of promoting the welfare of organization or one of its stakeholders. The extant research primarily focused on the antecedents of PSRB, and research on the consequences of the behavior is limited. In my dissertation, I adopt a combination of correlational and experimental designs to examine various employee outcomes of PSRB, including employee well-being and behavioral outcomes, as well as evaluative outcomes rated by others. The first manuscript focuses on rule breaking for …

The Experiences Of Women Who Have A Child Diagnosed With An Eating Disorder: A Narrative Inquiry, Jennifer Scarborough

Theses and Dissertations (Comprehensive)

Eating disorders (EDs) are serious, life-threatening illnesses that typically occur in adolescence. Immediate intervention is necessary in order to interrupt the associated behaviours. Typically, adolescents struggling with EDs minimize the severity the illness has on their psychological and physiological wellbeing. For this reason, family involvement in the intervention is strongly recommended. Additionally, family involvement has shown to increase the likelihood of better outcomes. Parents are typically tasked with the responsibility of making and monitoring meals and/or interrupting compensatory behaviours. These tasks often lead to high conflict. Despite the importance of parental involvement, predominantly, it is mothers who fulfill the intensive …

Characterizing Boreal Shield Lakes And Catchments To Predict Dissolved Organic Carbon Concentration And Composition In Relation To Safe Drinking Water Sources With Minimal Disinfection By-Products, Jordyn Atkins

Theses and Dissertations (Comprehensive)

Many Canadians rely on surface water sources for drinking water, most of which is disinfected with chlorine. Dissolved organic carbon (DOC) can react with chlorine to form potentially carcinogenic disinfection by-products (DBPs). The concentration and composition of DOC influences the type and amount of DBP formed.

Lake water varies widely in DOC concentration and composition as a result of the surrounding landscape that influences the terrestrial load of DOC to lakes and the extent of in-lake processing of DOC. Twenty-seven lakes of similar lake size but with varying catchment sizes over several orders of magnitude created a unique opportunity to …

Policing And Fatherhood Identities: A Gendered Analysis Of The Work And Home Experiences Of Police Fathers Before And During Covid-19, Danielle Thompson

Theses and Dissertations (Comprehensive)

Policing scholars have long pointed to police culture as an explanation for the negative behaviour of officers (Chan 1996), yet police culture also plays a crucial role in informing how officers make sense of their experiences both inside and outside of the organization. Much of the research on gendered experiences of police culture have focused on the experiences of women police, yet little attention has been given to the experiences of male officers in macho police culture. Moreover, there is a paucity of literature that has focused specifically on how police who are fathers perceive their own experiences, either at …

The Sower, The Story & Kingdom Space In The Gospel Of Mark, Susan Lankowski

Theses and Dissertations (Comprehensive)

The kingdom of God is an ambiguous term that Jesus does not explicitly define. Traditional scholarship has explained the kingdom in terms of its social, cultural and time aspects. Recent scholarship is examining the spatiality of the kingdom of God to uncover its characteristics as a “space.” Spatiality seeks to understand how humans interact with space. Space captures the experience of human life and activity and stories, and storytelling reveal that experience. It is at the intersection of space and storytelling that this project examines the kingdom of God. The Gospel of Mark is a story that grew from an …

The Impact Of Combined Flexion And Compression On The Mechanical Integrity Of The Annulus Fibrosus, Keaton Briar

Theses and Dissertations (Comprehensive)

Introduction: Intervertebral disc (IVD) herniation is characterized by an expulsion of nucleus pulposus (NP) material through the annulus fibrosus (AF). The AF contains two major adhesive structures, the intralamellar matrix and the interlamellar matrix, which act to maintain the strength of the AF and prevent NP material migration. As a herniation occurs, clefts form within the intralamellar matrix, pushing the NP between adjacent collagen fibres; meanwhile, delamination of the interlamellar matrix causes the NP to pool between layers of the AF. Further, herniation more readily occurs in a combined loading scenario of both compression and flexion. Flexion, and in particular …

Exploring Body Image Through The Injury And Rehabilitation Process Of Female Intercollegiate Gymnasts: A Multi-Case Study, Morgan Miller

Theses and Dissertations (Comprehensive)

Injury is a known inherent risk when participating in any physical activity. In particular, gymnasts exhibit high overuse and traumatic injury rates, attributed to the nature and volume of their training. The resulting injury and rehabilitation process can present many challenges, which are unique to each individual. During this time, body image perceptions may change which could potentially lead to unique cognitive, emotional, and behavioural responses. The purpose of this multiple case study was to explore body image throughout the injured female gymnasts’ rehabilitation experience and their return to intercollegiate sport. Participants included three National Collegiate Athletic Association (NCAA) Division …

Three Essays On Financial Economics, Zhe Peng

Theses and Dissertations (Comprehensive)

Essay 1 deals with a topic in market microstructure. It examines a type of trading mechanism called a speed bump. The speed bump was introduced to slow down incoming orders to reduce the informational advantage of certain high-speed traders who could exploit their information to take advantage of slower traders. In 2016, the Investors Exchange (IEX) became the first securities exchange in the US to introduce a speed bump. In our first essay, we use trading data from IEX to study this issue. IEX's speed bump includes two layers of delays: a fixed delay on displayed orders and a contingent …

Decipher The Effect Of Gamification In Harnessing Boredom And Improving Performance, Zhuoyi Zhao

Theses and Dissertations (Comprehensive)

My thesis investigates the effectiveness of gamification in harnessing boredom and improving performance in a repetitive work process. In video games, “loot” rewards are unpredictable, intermittent gains used to motivate players to repeat boring actions. In a 2 X 2 experiment, I examine how loot rewards in point form may impact 1) disengagement, which is an immediate outcome of boredom, and 2) performance in settings where the points have and do not have cash value, respectively. More specifically, I manipulate the level of point reward unpredictability (fixed versus loot) and whether point rewards have cash value (absent versus present).

Though mainstream acceptance for the 2SLGBTQ+ community is on the rise, elevated risks of mental health challenges still pervade this community, particularly for youth growing up in this changing environment. Based on previous literature citing the benefits of creative interventions and youth autonomy, the current study sought to explore the implementation of an online, peer-led creative writing program as a possible means to increase emotional, psychological, and social wellbeing in 2SLGBTQ+ youth. Twenty self-identifying 2SLGBTQ+ youth from across Canada were recruited to form two 10-week, online peer-led creative writing groups titled “Rainbow Writes”. Based on Lerner et al.’s (2003) “Five …

Debilitating Publics: Reading Canlit's Investigations Into Psycho-Affective Pain And Social Change, Rebekah Ludolph

Theses and Dissertations (Comprehensive)

The reception studies that comprise this dissertation take up contemporary depictions of psycho-affective pain from the field of Canadian literature that are embraced by prominent literary publics as an act of social responsibility. Each study contextualizes the publics that review these texts within the ongoing use of literary culture to justify the settler state’s land claim, nationally reparative reading practices, and trends in the therapeutic use of literature. Tracing the affective reactions documented within each text’s reception, this study finds that narratives that fail to locate the nation as a reparative project are susceptible to interpretive practices that pathologize, rather …

This study was descriptive, phenomenological, and qualitative in nature; it consisted of in-depth interviews with six male and six female participants. In their experience with MHI, seven participants experienced fear and sadness (depression and anxiety) and three of them …

Is It Just A Dream? How Attributions For Successful And Unsuccessful Social Mobility Attempts Maintain The Myth Of The American Dream, Erin Shanahan

Theses and Dissertations (Comprehensive)

Despite rising inequality making upward social mobility difficult, faith in the American Dream persists. Why is this the case? In six studies (five pre-registered), we demonstrate that in scenarios where hard work and ability are held constant, people praise the hard work and talent of individuals who successfully move up the social ladder while derogating these same characteristics among individuals who do not; a pattern of attributions which is likely to reinforce the American Dream. Further, conservatives explain mobility failure particularly in terms of personal shortcomings whereas liberals look to systemic disadvantages, attributions that in turn predicted lowered and heightened …

A Bioinformatic Analysis Of The Biosynthesis Of Carotenoids In The Copepod Tigriopus Californicus, Anchalya Balasubramaniam

Theses and Dissertations (Comprehensive)

Abstract

Biological pigments, also called biochromes, are coloured compounds which are displayed by a variety of life forms, including animals, due to selective colour absorption. The combination of light absorption and reflection enables each pigment to portray a distinct colour which results in the broad spectrum of colours we observe in our surroundings. Carotenoids are a large group of yellow, orange, and red biological pigments found in living organisms. Our current biomolecular knowledge of carotenoids is heavily derived from studying the pathway in photosynthetic prokaryotes, bacteria, fungi, and plants. Carotenoid pigments are exceptionally multifunctional as they act as photo-protectors against …

The Lived Experiences Of Developmental Disability Caregivers And Service Providers In Ontario, Tetyana Ali

Theses and Dissertations (Comprehensive)

Providing care for children with developmental disabilities (CwDD) is complex and is a life-long journey. Caregivers (CGs) of CwDD experience higher levels of stress, declining mental and physical health, feelings of isolation, diminished financial outcomes, and an overall lower quality of life. Additionally, they often face marginalization and numerous barriers when trying to access funding and supports. This study explored the experiences of CGs of CwDD in the context of Ontario and included the perspectives of CGs and service providers (SPs) to investigate the role the government played in CGs ability to provide adequate care.

Twenty participants were recruited through …

Microaggressions And Microaffirmations Experienced By Lgbtq2s+ People With Disabilities, Kathleen Mckee

Theses and Dissertations (Comprehensive)

This study explored the indirect, subtle, or unintentional discrimination (i.e., microaggressions) and positive identity-affirming actions (i.e., microaffirmations) that gender and sexually diverse (LGBTQ2S+) people with disabilities (PWD) experience in multiple life contexts. Previous literature has tended to focus solely on negative experiences, and little research has been conducted to understand their possible experiences of microaffirmations and how they may promote resilience and well-being. Intersectionality theory, minority stress theory, and Crip theory guided the study. The objectives were to explore microaggressions and microaffirmations experienced by LGBTQ2S+ PWD, as well as these individuals’ responses to microaggressions and microaffirmations. Semi structured qualitative interviews …

With the advent of both raw sensor and analysis-ready datasets, the need to monitor ecosystem disturbances is now more imperative than ever; yet the task is becoming increasingly complex with increasing sources and varieties of earth observation data. In this research, computer vision methods and tools are interrogated to understand their capability for comparing spatial patterns. A critical survey of literature provides evidence that computer vision methods are relatively robust to scale and highlights issues involved in parameterization of computer vision models for characterizing significant pattern information in a …

Relational Engagement At The Intersection Of Personal And Professional Identities: A Phenomenological Exploration Of The Experience Of Christian Therapists, Aaron Smith

Theses and Dissertations (Comprehensive)

Though Christian spirituality and therapeutic relationships are unique subjects, commonly found throughout literature pertaining to each topic is an emphasis on how people ought to approach and participate in relationship with one another. In other words, each subject represents a unique tradition of relational engagement. For therapists who practice Christian spirituality, it is possible, if not likely, that both traditions impact how they go about engaging with clients. Despite this, there is a lack of material exploring the experience of relational engagement when these traditions intersect. For this reason, I set out to explore what this experience is like for …

“Accept The Idea That Neurodiverse Kids Exist”: Dyslexic Narratives And Neurodiversity Paradigm Visions, Monica Van Schaik

Theses and Dissertations (Comprehensive)

The neurodiversity paradigm has received support from many autistic self-advocates and scholars. Although definitions of neurodiversity are always framed to include dyslexia, research into the neurodiversity paradigm that seeks the perspectives of dyslexic people is limited. This qualitative study sought to fill this gap by asking 12 self-identified dyslexic adults how they imagined their life stories would change within a neurodiversity paradigm. A narrative inquiry methodology was combined with the guiding principles of participatory action research and dyslexic methodology. Dyslexic ways of knowing were engaged and illuminated in the research design, writing process and findings. Emergent themes revealed participants’ lived …
