Learning And Working Together: Invoking Systems’ Change Through Inter-Organizational Collaborative Principles And A Learning Community Framework, Brandon Hey

Theses and Dissertations (Comprehensive)

Local communities face significant challenges such as increased inequality, immigration, and global climate change. In order to address these challenges whole cities have to innovate and learn together. In this thesis, I introduce the Learning Community (LC) model, a new way of collaborating and creating collective impact that emphasizes learning, alongside collective impact, as a central strategy to addressing complex social challenges. In a LC, members value the continuous pursuit of knowledge, feedback, and experimentation as well as the flow of information and resources between academic institutions and practice groups. The value of learning is built into key structures …

Bye Bye Binary: Exploring Non-Binary Youths' Experiences Of Mental Health, Discrimination, And Community Belongingness, Ellis Furman

Theses and Dissertations (Comprehensive)

In recent years, there has been an increase in research focusing on the impacts of social exclusion and discrimination on the mental health of transgender populations. Despite this, few studies have focused on the experiences of gender non-conforming, or “non-binary” individuals. This community-based participatory research (CBPR) study (N = 10) used the arts-informed method of body mapping, individual interviews, and group discussions to examine non-binary young peoples’ experiences of discrimination in relation to mental health. Participants consisted young people (ages 16-25) living in Waterloo, Ontario. A visual analysis, thematic analysis, and member-checking session were employed to analyze collected data. …

The Complexity Of Electron Transport: A Study Of Variegation Through Chemical Inhibition Of Plastoquinol Terminal Oxidase (Ptox) In Tobacco (Nicotiana Tabacaum), Hillary Peon

Theses and Dissertations (Comprehensive)

The photosynthetic electron transport (PET) chain relies on the chlorophyll and carotenoid biosynthetic pathways for pigments that harness light, and protect the photosynthetic apparatus from damage by light. The pigment pathways also connect to the PET chain through electron transfer where the plastoquinol (PQ) pool accepts electrons from phytoene desaturase (PDS) of the carotenoid pathway and the aerobic cyclase (ACS) of the chlorophyll biosynthetic pathway. Genetic studies have shown a plastoquinol terminal oxidase (PTOX) protein functions to regulate the redox state of the PQ pool. Without PTOX to maintain balance between the two redox states of the PQ pool it …

Developing And Testing Quality Indicators For Seriously-Ill Home Care Clients In Ontario, Lisa Harman

Theses and Dissertations (Comprehensive)

Introduction Currently in Ontario, there is no set of quality indicators for use in palliative care settings. Palliative care research tends to focus heavily on those with cancer diagnoses, and therefore potentially misses those with other life limiting illnesses. The current study aims to develop a preliminary set of quality indicators relevant for seriously-ill individuals for use in the community. Methods Secondary analysis of Resident Assessment Instrument for Home Care (RAI-HC) data from 2006-2013 (n=263,767) was used to develop QIs thought to be relevant to the needs of seriously-ill home care clients. Seriously-ill clients were defined as those with a …

Quantifying The Interactions Of Nickel With Marine Dissolved Organic Matter Using Fluorescence, Elissa Dow

Theses and Dissertations (Comprehensive)

Nickel (Ni) is a versatile metal with an abundance of applications, namely its role in stainless steel, electronics, and batteries, making it a popular choice in industry. Unfortunately, with increasing demand and production comes higher amounts of Ni pollution. Nickel enters ocean waters - either directly or indirectly - and can have profound effects on marine life. Nickel has been established as a toxicant to a variety of aquatic biota, with the divalent cation (Ni²⁺) thought to be the most bioavailable fraction and thus the most toxic. Having a reliable means of quantifying free Ni ion is pertinent …

Developing A Hydrological Monitoring Program For Ponds In Wapusk National Park, Manitoba, Using Water Isotope Tracers, Stephanie Roy

Theses and Dissertations (Comprehensive)

Northern lake-rich landscapes are vulnerable to increases in surface air temperatures and are changing in dynamic ways. Current meteorological records indicate that some of the greatest warming in the past century has occurred in the Hudson Bay Lowlands (HBL). As the HBL is an extensive wetland consisting of hundreds of thousands of shallow lakes and ponds, it is difficult to anticipate the long-term implications that climate change will have on pond water balance. To develop and implement long-term monitoring of hydrological conditions, sampling of pond water isotope composition has occurred during the past six years in Wapusk National Park (WNP), …

Exploring Metacognition, Multitasking And Test Performance In A Lecture Context, Fatma Arslantas

Theses and Dissertations (Comprehensive)

Multitasking has become more prevalent with recent advancements in technology (Judd, 2014; Junco & Cotten, 2012). Many self-report studies, and the few available experimental manipulations, consistently indicate that media multitasking is related to decrements in learning. The present study extends the current literature by explicitly documenting students’ responses to media-based interruptions to learning. The current study also documents other behaviours students engage in that may or may not be related to multitasking when technology is available during lectures. In addition, the study explores the role of metacognition as a contributor to learning in a media-rich educational setting. In total, 118 …

Dynamic Assessment Of Early French Immersion Literacy Learning Competencies, Alexandra Bellissimo

Theses and Dissertations (Comprehensive)

French Immersion programming in Canada is not always an inclusive environment for all learners. Students with language disabilities or delays are often placed into English-only programming when difficulties arise in French immersion programming. This study aimed to establish a method of identification of reading difficulties, in either language, early in the reading process. Such an assessment would allow educators to intervene and assist these students, and all students, with reading and vocabulary development in their second language of French before these language issues can negatively affect learning.

Essential to language learning in immersion programs is the development of speech perception …

Young Leader's Sustained Engagement In Environmental Action: A Narrative Inquiry, Sara Wicks

Theses and Dissertations (Comprehensive)

Young people have been identified as key stakeholders in taking a leadership role in addressing environmental issues, but more research is required to find out how to sustain young people’s motivation for environmental action over time. The present study investigated this through narrative interviews with eleven environmental leaders who attended a conference called IMPACT! Youth Conference for Sustainability Leadership in 2009 or 2011. Drawing upon the literature on life paths to environmental action (Almers, 2013; Chan, 2009; Chawla, 1998, 1999; Harré, Tepavac, & Bullen, 2009) the interviews incorporated an exercise that asked participants to plot important events in their lives …

Determination Of Silver Binding To Natural Organic Matter Using Ion Selective Electrode, Mona Muhawwis Alshammari

Theses and Dissertations (Comprehensive)

Natural organic matter (NOM) is considered an important factor in the protection of the aquatic environments; organic ligands can complex with metals, to decrease their toxicity and bioavailability. NOM is measured as dissolved organic carbon (DOC) in mg C/L. Silver metal can enter into the aquatic environment from natural and anthropogenic sources, and is found in different chemical forms. Free silver ion (Ag+) is considered as the most toxic form of the metal. However, it can form complexes with both inorganic and organic ligands, such as ammonia, chloride, hydroxyl, carbonato, phosphato, and thiol groups. Thiol is the most important ligand …

The Social Self-Compassion Scale (Sscs): Support For A Multi-Domain View Of The Self-Compassion Construct And Its Relevance To Anxiety, Alison Flett

Theses and Dissertations (Comprehensive)

Self-compassion refers to the tendency to be kind and understanding towards oneself in times of failure rather than responding to such situations with harsh self-criticism. There is reason to believe on the basis of existing research that self-compassion is particularly relevant within the social domain. As such, this thesis is focused on describing and evaluating the Social Self-Compassion Scale (SSCS), which was developed for the purposes of this research and measures the degree to which individuals tend to be kind and understanding towards themselves when confronted with social adversity. This thesis begins by describing Studies 1 through 3, which were …

Reading In Arabic Script: A Cross-Linguistic And Cross-National Study, Asma Amin

Theses and Dissertations (Comprehensive)

The current study examined within- and cross-language predictors of word reading and reading comprehension among groups of Arabic-English bilingual children in different language learning environments. A total of 80 children were tested, forty Arabic-English bilingual children recruited from Saudi Arabia and forty Arabic-English bilingual children were recruited from Canada. Both groups completed parallel measures of word-level reading, reading comprehension and vocabulary in Arabic and English. Results indicated that the underlying components related to within- and cross-language word reading and reading comprehension varied across groups. Within-language results demonstrate that English morphological awareness was significantly related to English word reading in both …

An Assessment Of How Plant And Mycorrhizal Communities Have Been Affected Along A Mine-Impacted Watershed In The Northwest Territories, Kevin Maccoll

Theses and Dissertations (Comprehensive)

Giant Mine is an inactive gold mine located nine kilometers north of Yellowknife, Northwest Territories. Giant Mine has been the source of arsenic trioxide for the Baker Creek watershed since it opened over 60 years ago. Although arsenic levels in the creek are above the limits considered to be biologically relevant, there is no concrete evidence that plants and mycorrhizae have actually been affected. This study provides an initial assessment of the impacts mining activity at Giant Mine has had on plants and mycorrhizae in the Baker Creek watershed. Nine sites were sampled around Giant Mine: five sites downstream from …

Three Essays On Banking, Capital Market Frictions And Corporate Payout Policy, Hosein Nooriaan

Theses and Dissertations (Comprehensive)

The prevalence of financial market frictions is far from uncommon. Between 1970 and 2011, Laeven & Valencia (2012) identify 147 banking crises, along with 218 episodes of currency crises, and 66 episodes of sovereign debt default. Thus, understanding a firm’s behavior in the presence of financial crisis is an important issue for future financial research. My dissertation explores corporate payout and liquidity policy either during a financial market crisis, or in anticipation of a financial market crisis.

In the first essay, “Capital Market Friction and Corporate Payout Policy”, I focus on the role of supply of capital on corporate payout …

Moving And Improving: Investigating Physical Activity Patterns For Children With Autism Spectrum Disorder (Asd), Kristen Wright

Theses and Dissertations (Comprehensive)

The primary characteristics of ASD fall into three broad categories: communication problems, difficulty relating to people, things and events, and repetitive body movements and behaviours. According to the Government of Canada, in 2015, the prevalence of ASD was approximately 1% in North America and rising. The Canadian Physical Activity guidelines state clearly that the majority of elementary and secondary school aged children and youth (5-17 years old) should participate in 60 minutes of moderate-to-vigorous physical activity daily. Unfortunately, only 9% of this general population has been successful in obtaining the suggested amount of physical activity daily. However, for individuals with …

Three Essays On Corporate Governance And Politically Connected Firms, Justin Mindzak

Theses and Dissertations (Comprehensive)

In this dissertation three essays on corporate governance and politically connected firms are presented. The first essay “Interlocked Boards of Directors, Corporate Governance and Earnings Quality” studies the effects of interlocked boards of directors on voluntary governance disclosures, governance practices and earnings quality. The Canadian environment, where director interlocks are prevalent, is examined. A checklist of twenty voluntary disclosure measures from proxy statements is developed and a direct measure of interlocking directorships is employed. It is found that interlocked boards of directors are negatively associated with voluntary governance disclosures and positively associated with earnings quality. From an accounting perspective, greater …

Relationship Commitment As A Moderator Of The Effects Of Promotion Focus On The Pursuit Of Change And Stability Relationship Goals, Sarah Wall

Theses and Dissertations (Comprehensive)

According to regulatory focus theory, promotion-focused people should experience stronger engagement toward goals which are framed as leading to advancement. However, because situations can afford or constrain people’s regulatory preference, the present research investigates how promotion-focused individuals’ preference for change and advancement may be altered by the affordances offered by the broader contextual environment (i.e., their romantic relationship). I hypothesized that among participants in romantic relationships, those with a promotion focus (chronic or induced) would engage less in relationship goals when they reflected on how completing these goals would positively change their romantic relationship from its current state, compared to …

Spicing Things Up: How Regulatory Focus Affects People’S Willingness To Try Novel Activities With A Romantic Partner, Jill Prince

Theses and Dissertations (Comprehensive)

While spending time together is an important interpersonal goal for most romantic couples, “spicing things up” through participation in novel activities is a route commonly recommended and used in order to enhance relationship quality. However, relationship research has yet to focus on whether some people may have a greater proclivity toward pursuing these types of activities than others. The present research examines whether people’s motivational states – specifically, their regulatory focus orientation – may influence their desire to pursue novel activities with their romantic partners. In Study 1, participants (N = 110) indicated their regulatory focus, relationship quality, and …

An Examination Of Imagined Contexts: The Unreliability Of Context-Dependent Memory Effects In Recall, Caitlin J. I. Tozios

Theses and Dissertations (Comprehensive)

It is generally accepted that the environmental context present during memory encoding serves as an effective cue for recall if reinstated during retrieval. Participants who perform a free recall test in the same context as that during which they learned a set of words, often remember more words than participants who experience a context mismatch from encoding to retrieval. This is referred to as the context-dependent memory effect and forgetting due to a change in context is referred to as context-dependent forgetting. Recent evidence suggests that contexts need not always be physical but can be mentally generated or imagined and …

Exploring The Middle Path: Effects Of Ethical And Secular Mindfulness On Well-Being And Prosocial Behaviour, Siyin Chen

Theses and Dissertations (Comprehensive)

Mainstream mindfulness programs generally remove Buddhist ethics, causing some to worry they may encourage self-indulgence and have limited capacity to promote well-being. We compare the effects of secular and ethical mindfulness (incorporating principles of non-harm and interdependence) on well-being and prosocial behaviour. Participants (N = 621) completed six days of ethical or secular mindfulness or active control exercises. Secular and ethical mindfulness practices both reduced stress and self-image concerns, and increased life satisfaction and self-awareness. Ethical mindfulness also enhanced personal growth. Participants were also invited to donate to a charity. Both mindfulness practices potentiated effects of trait empathy on …

Investigating The Effects Of Mindfulness On Children’S Executive Function, Emotional Regulation, Stress, And Academic Performance Compared To A Control Condition, Lerna Hanceroglu

Theses and Dissertations (Comprehensive)

Mindfulness is a growing field in the study of psychological well-being, with reports of individuals experiencing increases in resilience and reduced stress. The current research on mindfulness lacks information on a comprehensive analysis on the relationship between mindfulness and executive function, emotional regulation, stress, and subsequent academic performance for children. Additionally, studies contain methodological issues, such as the absence of active control groups. Hence, the current study assessed the effects of mindfulness training on children’s executive function, emotional regulation, stress, and academic outcomes compared to an active control group. There were 51 younger children from grades 2 to 4 (Mean …

Children's Letter Learning: The Effect Of Manipulating Visual Complexity On Children's Letter Learning, Bahar Amani

Theses and Dissertations (Comprehensive)

As a growing presence in homes and schools, technology plays an important role in the way that children learn in their environment. The early integration of technology within education reflects the promise of computer-based educational tools to facilitate early learning in children (Grant, Wood, Gottardo, Evans, Phillips, & Savage, 2012). Young learners are reported to be challenged with high levels of distractibility that can hinder their ability to learn in particular conditions and contexts (Fisher, Godwin, & Seltman, 2014). This can be a problem when considering that educational materials are often designed to be elaborate to keep young learners interested. …

The Effect Of Twist On The Mechanical Properties Of The Intervertebral Disc, Maxine Harvey-Burgess

Theses and Dissertations (Comprehensive)

Introduction: Intervertebral disc (IVD) herniation is a common injury to the IVD and a frequent source of low back pain. IVD herniation occurs when the nucleus pulposus migrates through both the inter- and intralamellar matrices of the annulus fibrosus (AF). There are a number of mechanical risk factors associated with herniation, including repetitive flexion and twist. In vivo, twist combined with repetitive flexion has been associated with increased experience of low back pain and herniation. Additionally, in vitro, when repetitive flexion is combined with twist, IVD herniation occurs more easily than repetitive flexion alone. However, the mechanisms behind …

The Experiences Of Athletes, Parents, And Coaches With The Long-Term Athlete Development Model (Ltad) In Youth Soccer Academies, Kody Watson

Theses and Dissertations (Comprehensive)

The Long-Term Athlete Development Model (LTAD) has been developed to allow children the best chance of engaging in lifelong sport and physical activity. The LTAD focuses on long-term development, not short-term success, which allows for the best opportunity of sport participation and optimal sport potential throughout life (Balyi, Way, & Higgs, 2013). Research surrounding the LTAD model has stated that there is a lack of empirical evidence of the model being utilized within sport, as some researchers believe that it is more theoretical than practical (Lloyd & Oliver, 2012). However, even with this criticism of the LTAD model, Canadian sport …

Neural And Social Mechanisms Behind The Social Transmission Of Food Preference, Chelsey Damphousse

Theses and Dissertations (Comprehensive)

Research on the social transmission of food preference (STFP) has shown that preferences for specific foods can be transmitted between conspecifics (Bilkó et al., 1994; Wrenn et al., 2003; Hikami et al., 1990; Galef et al., 1984; Galef & Wigmore, 1983; Lupfer et al., 2003). Although these findings provide an understanding of how food related information is shared, none explore the influence that personality may have on various factors of STFP, as well as how this transmission may occur in a naturalistic foraging setting. In the current thesis, individual personality was assessed and rats were placed into …

An Evaluation Of Older Adults’ Perceptions Of Psychological Well-Being When Participating In Community Centre Programs, Kayla Rellinger

Theses and Dissertations (Comprehensive)

Multi-purpose organizations, such as community centres, provide opportunities for individuals to participate in various physical and social activities. Although, it has been well established that community centres provide the opportunity and environment to promote health behaviour changes among older adults (Jones et al., 2013; Stewart, 1997; Wallace et al., 1998), there is a dearth of research differentiating between physically active and non-active community centre programming. The purpose of the current study was to evaluate whether participating in community centre programming influenced four key measures of perceived psychological well-being, as well as, to evaluate whether the perceived psychological well-being of community …

Experiences Of Racialized Service Providers Who Work With Racialized Clients: Functions And Constraints Of Master And Counter-Narratives Of Helping, Racism, And Vicarious Racism, Prapti Giri

Theses and Dissertations (Comprehensive)

What are the experiences of racialized frontline workers? How do they experience vicarious racism? I interviewed 8 frontline workers who were involved in counseling racialized individuals. The narrative paradigm, constructivist self-development theory (CSDT), and critical race theory (CRT) were the theoretical frames that guided the interviews and data analysis in order to answer these questions. I conducted a structural narrative analysis, which revealed how participants utilized assumptions from master narratives and at other times countered them. Interviewees occasionally stepped outside of the master narrative entirely, for example, by rejecting the categorization of race. According to CSDT, our meanings are determined …

Exploring Police Officers' Perceptions Of Mobile Crisis Rapid Response Teams Within A Nodal Policing Framework, Trevor Viersen

Theses and Dissertations (Comprehensive)

An increasing portion of police service resources are being dedicated to interactions involving persons with mental illness (PMI). As a result, Mobile Crisis Rapid Response Teams (MCT) comprised of mental health professionals have been recently implemented to assist police officers in more efficiently handling police calls for service involving PMI. The current ethnographic study used data collected through researcher ride-alongs with police officers at a mid-sized police service in Ontario to assess how police officers interact with and perceive MCTs. Results from thematic analysis indicated that officers value the skill sets possessed by MCT workers, had relatively positive perceptions towards …

Meeting The Needs Of Victims: An Examination Of Victims' Coping Strategies And Victim Services In Canada, Jenniffer Olenewa

Theses and Dissertations (Comprehensive)

Victimization creates harms that can take an emotional and financial toll on victims and their communities. As a result of the trauma, many victims will have physiological, safety, and emotional needs that require support. All community members benefit when victims can receive support that meets the needs generated by the harms of a victimization. This mixed-methods study using Canadian data examines what factors contribute to victims engaging in behavioural changes to meet their safety needs, and explores how Victim Service workers view their role in assisting victims to meet their needs. Using data from the 2014 General Social Survey, Study …
