Molecular Studies Of 5-Azacytidine-Induced Early-Flowering Lines Of Flax, Megan A. House

Theses and Dissertations (Comprehensive)

Several early-flowering flax (Linum usitatissimum L.) lines were derived from treatment of germinating seeds with 5-azacytidine in 1990. These lines are also shorter, have fewer leaves, and their DNA is hypomethylated, relative to their corresponding controls. The work presented in this thesis used early-flowering and control lines of the Royal (R) flax genotype, and the Large (L) flax genotroph. Firstly, levels of cytosine methylation were measured over a 24-hour period in the early-flowering line RE2 and its control (RC), using an HPLC method. Secondly, to determine the response of the flax lines to short-day conditions, control and early-flowering …

An Apple A Day: Exploring Food And Agricultural Knowledge And Skill Among Children In Southern Ontario, Shannon Alberta Kornelsen

Theses and Dissertations (Comprehensive)

While the literature on food has somewhat addressed rudimentary food skills and their importance in the creation and maintenance of a healthy population, there remains a serious lack of research into the importance of food and agricultural skills and knowledge transference to children, especially given the rise in diet-related illnesses. This study focuses on the perceived importance of food and agricultural education initiatives, as well as the opportunities and barriers that exist within the elementary school classroom to incorporate food and agricultural topics, in the context of southern Ontario, specifically Wellington County. Drawing on Wilkin's concept of ‘food citizenship’ as …

Interviewing Children About Repeated Events: Does Mental Context Reinstatement Improve Young Children’S Narratives?, Donna M. Drohan-Jennings

Theses and Dissertations (Comprehensive)

This study examined mental context reinstatement (MCR) as a technique to increase the quantity and accuracy of information provided by children during repeated-event narratives. Children (N = 46, 4-, 5- and 6-year olds) participated in four repeated laboratory activities and were interviewed 4-7 days later about the last occurrence with a control or MCR interview, including both a free narrative and specific questions about the events. Older children (6-year olds) provided a greater number of accurate instantiations (specific details) compared to 4-year olds. Five and 6-year olds reported a greater number of instantiations than 4-year olds, but this effect …

Concussions In Ice Hockey: Baseline Testing, Reporting Accuracy, And Cervical Functioning, Craig J. Coghlin

Theses and Dissertations (Comprehensive)

The purpose of this study was threefold: firstly, to demonstrate the utility of the SCAT2 as both a baseline measurement and a tool to aid in the decision making process following the occurrence of a concussion; secondly, to assess the accuracy of reporting and/or relaying a diagnosis of a concussion; and finally to attempt to measure a relationship between cervical spine functioning and past concussion occurrence. Eighty hockey players were assessed for cognitive, neuropsychological, and physical measures pertaining to concussive injuries within ice hockey. The results of the study showed a marked underreporting of concussions due to either fear of …

An Evaluation Of A Dialogic Book-Reading Program For At Risk Children, Daniel Anthony Colangelo

Theses and Dissertations (Comprehensive)

Children from low-income backgrounds are at a higher risk for reading difficulties partly because they are read to less frequently in the home (Adams, 1990). When shared reading does occur in low-income homes, it is usually of poorer quality when compared to reading in middle- or upper-income homes (Arnold, Lonigan, Whitehurst, Epstein, 1994). Dialogic reading, a form of enhanced discussion and structured questioning during shared-book reading, can be a cost effective way of improving the language and literacy skills of young children. The current research examines the effectiveness of a community-based, four-month dialogic reading intervention called the Dialogic Reading Club …

Mathematical Modeling And Control Of Nonlinear Oscillators With Shape Memory Alloys, Mohamed Bendame

Theses and Dissertations (Comprehensive)

Shape memory alloys (SMAs) belong to an interesting type of materials that have attracted the attention of scientists and engineers over the last few decades. They have some interesting properties that made them the subject of extensive research to find the best ways to utilize them in different engineering, biomedical, and scientific applications. In this thesis, we develop a mathematical model and analyze the behavior of SMAs by considering a one degree of freedom nonlinear oscillator consisting of a mass connected to a fixed frame through a viscous damping and a shape memory alloy device. Due to the nonlinear and …

Understanding Academic Success For Onkwehonwe (Indigenous) Students Through The Use Of An Onkwehonwe'neha (Indigenous Methodology), Ashley Victoria Dorothy Johnson

Theses and Dissertations (Comprehensive)

School-retention rates for Indigenous (Onkwehonwe) students are disproportionately lower than the non-Indigenous population in Canada (Mendelson, 2006). Currently, few studies on Native education acquire the perspectives and knowledge from successful OS. Many nonpersistence factors for OS have been uncovered, but few studies have offered solutions. Additionally, there is minimal (re)search using an Indigenous methodology (Onkwehonwe’neha) in the exploration Onkwehonwe education. This search (study) focused on the perspectives and experiences of six successful OS (i.e., five graduate students and one entering a graduate program). Two of the six participants were Aboriginal student-services coordinators at accredited universities within Ontario, Canada. Through the …

Reconstructing Sex: Women Having Sex With Women, Alixandra Holtby

Theses and Dissertations (Comprehensive)

This study examines the experience of exclusion from the dominant understandings of sex for women who have sex with women, including queer, pansexual, bisexual, and lesbian women. Using ideas of the constructed nature of sex, particularly the use of sexual scripts (Simon & Gagnon, 1973), as well as the (hetero)sexist context in which these scripts are formed, qualitative interviews with 11 queer, pansexual, bisexual, and lesbian women were analyzed regarding their development of their understandings of what constitutes sex, their expectations and experiences of sex, their negotiation of desire and sexual identity, and their perspectives on sex between women and …

A Qualitative Examination Of Sport Transitions In First Year Collegiate Female Athletes, Carolyn Mcewen

Theses and Dissertations (Comprehensive)

First year student athletes transitioning from high school to university experience simultaneous transitions in athletics, academics, social lives, family structures, support systems, and peer sport groups. These changes in their personal, social and occupational lives, can impact them cognitively, emotionally and behaviourally (Taylor & Ogilvie, 1994). The purpose of this study was to qualitatively examine the multi-dimensional transition experience of first-year collegiate athletes transitioning to higher level sports. A sample of eleven female varsity hockey, basketball, or volleyball athletes participated in two semi-structured interviews at beginning of the season and midseason. The first series of interviews were conducted face-to-face, with …

Interfaith Grand River: The Potential And Limits Of Dialogue To Transform Participants And Impact Communities, Jonathan Andrew Napier

Theses and Dissertations (Comprehensive)

The purpose of this thesis is to analyze the dynamics between an interfaith dialogue group and its community. While interfaith dialogue is used for various reasons, I will study how Interfaith Grand River (IGR) deals with issues of religion in Canadian society through their monthly discussions. IGR began in September 2001 as an initiative to ensure different religious adherents in the Kitchener/Waterloo and surrounding area could meet regularly to discuss different faith topics and develop relationships. IGR serves as an illustration to compliment the theoretical works on the limits and possibilities of dialogue. Data on IGR has been derived through …

Insights Into The World Of Pea Nodulation Using The Low Nodulator R50, Scott Clemow

Theses and Dissertations (Comprehensive)

Cytokinin oxidase (CKX) is the enzyme responsible for the degradation of cytokinin, a class of adenine-based plant hormones that stimulate cell division, among other physiological processes. The pea mutant R50 is characterized by having a pale leaf phenotype, dwarf stature, few lateral roots, low nodule formation, and elevated levels of endogenous cytokinins in its shoots, roots and nodules. When compared to that of the wild-type Sparkle, total CKX activity is low but the transcript levels of PsCKX1 are significantly higher. In this study, I investigated the expression of PsCKX1 throughout the development of a nodule and the localization of PsCKX1 …

The Thompsons’ Town: Family, Industry, And Material Culture In Indiana, Ontario, 1830–1900, Laura Kathleen Quirk

Theses and Dissertations (Comprehensive)

This study considers the industrial development and subsequent decline of the town of Indiana, Ontario, during the years 1830–1900, a period of intense socioeconomic change and population mobility. This dissertation applies interdisciplinary frameworks, especially those derived from archaeological inquiry, in order to assess the documentary evidence and also the material culture of nineteenth-century Indiana, in the interests of understanding both the historic process of rural industrialization by means of a case study and also the elusive processes of social and familial interaction in the Ontario towns caught up by the swirl of socioeconomic change during this period. How, and why, …

Exploring The Concepts Of Partnership And Their Implications For Hiv And Aids Prevention And Care In Two Ghanian Communities, Jonathan Lomotey

Theses and Dissertations (Comprehensive)

This study was an exploration of the concepts of partnership in the La and Nsawam-Adoajiri communities of Ghana and their implications for HIV and AIDS prevention, treatment, care and support. Using qualitative data gathering methods, this study sought to discover what is referred to as a partnership, how it is initiated, why it is initiated, the meanings ascribed to it, and its structure and processes in either community. The study further sought to understand how the concepts of partnership in each community could facilitate the development of an effective community-based initiative for HIV and AIDS prevention and care in either …

The Warrior Women Of Transnational Cinema: Gender And Race In Hollywood And Hong Kong Action Movies, Lisa Funnell

Theses and Dissertations (Comprehensive)

In The Warrior Women of Transnational Cinema, I consider the significance of transnational Asian action women in the post-1997 Hong Kong cinema; more specifically, I explore how Pan-Asian (e.g. Michelle Yeoh, Pei Pei Cheng, Ziyi Zhang), Asian American (Lucy Liu, Maggie Q, Marsha Yuen), and Asian Canadian (e.g. Francoise Yip, Charlene Choi, Kristy Yang) warrior women function as a source of transnational female identity for local, Pan-Asian (i.e. East and Southeast Asian), and diasporic Asian audiences. I argue that the post-1997 Hong Kong cinema—and not Hollywood—has offered space for the development of Pan-Asian and Asian North American screen identities …

The Dance In Contexts: Exploring The Complexity Of The Helping/Healing Process With A Focus On Client Satisfaction, Margriet De Zeeuw Wright

Theses and Dissertations (Comprehensive)

This multiperspectual study was undertaken to explore and describe the complexity of the helping / healing process in a community-based counselling centre. The standard for evaluation was client satisfaction. Client and worker participants’ perspectives were sought in an exploration of whether and / or how the client as an individual, the worker both as an individual and as a staff member, the therapeutic relationship, and the organizational setting impacted client satisfaction.

Former clients of the agency (N=400) were asked to complete Greenfield, Attkisson, and Pascoe’s (©2005) Service Satisfaction Scale (SSS-30). Respondents (N=73) were profiled using descriptive statistics which led the …

Self-Knowledge And Rationality, Stephen Blackwood

Theses and Dissertations (Comprehensive)

Several basic asymmetries are normally thought to exist between first- and third-person present-tense ascriptions of mental states. First of all, when a speaker ascribes, for instance, a belief that p to another, she must do so on the evidence provided by the utterances and actions of the other. However, it at least appears that typically she need not do so when ascribing a belief to herself. In other words, there is an immediacy to a self-ascription of a belief (that is, an utterance of the form ‘I believe that p’) that thirdperson ascriptions (‘He believes that p’) lack. …

Rethinking Biodiversity Conservation Effectiveness And Evaluation In The National Protected Areas Systems Of Tropical Islands: The Case Of Jamaica And The Dominican Republic, Suzanne Mae Camille Davis

Theses and Dissertations (Comprehensive)

Island conservation theory and practice with regard to conservation of tropical terrestrial biodiversity in protected areas systems has yet to be adequately addressed in conservation literature. This knowledge gap is identified as a key contributor to the adoption of scientific principles for in situ biodiversity conservation, and “universal” conservation and protected area management paradigms that are unsuitable for island contexts and geographical scale. The underlying assumption is that “universal” concepts of biodiversity conservation, protected areas management, and evaluation of their effectiveness are transferable to the ecological and socio-economic contexts of tropical islands. The expected outcome of this knowledge transfer is …

Grounding Diaspora In Experience: Niagara Mennonite Identity, Cynthia Anne Jones

Theses and Dissertations (Comprehensive)

This qualitative case study grounds theoretical notions of diaspora in personal accounts of Russian Mennonites living on the Niagara peninsula of Canada. The focus is on successive, complex interrelationships with ‘place’ (in a fixed sense, and a globally connected sense), with attention to gender, generation, and life-stage. How have these individuals experienced diaspora, and how has this influenced their culture and identity? Interrelationships with place are examined within an analytical framework composed of three key elements as identified in diaspora literature: cultural hybridity, social heterogeneity (internal divisions), and responsibility flows. The results are both descriptive and theoretical, featuring first person …

The Problem Of Causal/Explanatory Exclusion, Dwayne Moore

Theses and Dissertations (Comprehensive)

The problem of mental causation, at least in one of its most basic forms, is how to reconcile two plausible but potentially incompatible intuitions. The first intuition is that the mind makes a difference in the world. For example, I am writing this paragraph for certain reasons, and before long I will stop to eat something because of certain desires for food. Seemingly, these reasons and desires play a role in what happens. The second intuition is that the physical world is causally complete, so everything that happens is the result of the movement of physical particles. For example, the …

But Where Will They Build Their Nest? Liberalism And Communitarian Resistance In American Cinematic Portrayals Of Jewish-Gentile Romances, Holly A. Pearse

Theses and Dissertations (Comprehensive)

This dissertation analyzes approximately fifty American films that feature predominantly heterosexual interfaith/intercultural romantic, sexual or marital relations between Jewish and Gentile protagonists. It asks what political or social ideals can be illustrated by these portrayals, and how these films can be taken cumulatively to explore trends in modern life. The author places liberalism at the heart of the mainstream Hollywood discourse on intermarriage, and shows how films that run counter to the expectations of liberal romances may reflect communitarian critiques of liberal tenets.

The issue of intermarriage is contextualized with a discussion of the endogamous tradition in Judaism, and by …

Tundra Snow Cover Properties From In-Situ Observation And Multi-Scale Passive Microwave Remote Sensing, Andrew Rees

Theses and Dissertations (Comprehensive)

Tundra snow cover is important to monitor as it influences local, regional, and global scale surface water balance, energy fluxes, and ecosystem and permafrost dynamics. Moreover, recent global circulation models (GCM) predict a pronounced shift in high latitude winter precipitation and mean annual air temperature due to the feedback between air temperature and snow extent. At regional and hemispheric scales, the estimation of snow extent, snow depth and, snow water equivalent (SWE) is important because high latitude snow cover both forces and reacts to atmospheric circulation patterns. Moreover, snow cover has implications on soil moisture dynamics, the depth, formation and …

Bringing Medicine To The Hamlet: Exploring The Experiences Of Older Women In Rural Bangladesh Who Seek Health Care, Md. Abul Hossen

Theses and Dissertations (Comprehensive)

The purpose of this study was to explore the experiences of older women in rural Bangladesh who seek health care. Qualitative methods were used to collect data from 17 older women in Bibirchar Union, Sherpur District, Bangladesh in June 2006. The study is intended to generate findings to help policy makers plan appropriate strategies to improve the health of this highly vulnerable population group.

The findings reveal that women’s culturally and socially determined roles greatly impair their health and play an important role in health-seeking behaviour through a complex web of social, economic, religious/cultural and behavioural interrelationships and synergies that …

An Exploration Of Counselling Practices With Women Survivors Of Childhood Sexual Abuse: Should Therapists Ask About Thoughts Or Behaviour Involving Sex With Children?, Angela Karen Hovey

Theses and Dissertations (Comprehensive)

Helping professionals and women, themselves, have been reluctant to recognize or acknowledge that females can and do sexually abuse children and adolescents. Research has also demonstrated that females most at risk to abuse children are those who were themselves victims of severe child sexual abuse (CSA) The purpose of this research was to explore whether or not current counselling practices with women survivors of CSA reflect the belief that women do not sexually abuse children. This study also focuses on whether or not therapists create space for discussion about thoughts and behaviour involving sexual abuse of children and adolescents with …

Dhamma Education: The Transmission And Reconfiguration Of The Sri Lankan Buddhist Tradition In Toronto, Deba Mitra Bhikkhu

Theses and Dissertations (Comprehensive)

This research documents the transition of a religious tradition from a foreign-born generation to a new generation who call Canada home. It examines how first-generation Sri Lankan Buddhists in Toronto transmit their Buddhist tradition to their Canadian children, how the latter receive what is passed on to them, and what happens within the tradition through the process of transmission and reception. These issues are of paramount concern not only for Buddhist communities in North America but also for other immigrant and refugee groups undergoing the process of resettlement. Working with two Sri Lankan temples in Toronto, the Toronto Mahavihara and …

Intentionality, Responsibility, And Social Grouphood, Sherisse Webb

Theses and Dissertations (Comprehensive)

This dissertation examines the theories of collectivity or social grouphood presupposed by accounts of collective intentionality, collective action and collective moral responsibility. I consider the intentionalist theories of social grouphood proposed by John Searle and Margaret Gilbert, Larry May’s conceptual account of social grouphood, and Paul Sheehy’s realist conception of social grouphoood. All three approaches are found to be problematic. The theories of Searle and Gilbert fail to adequately explain the causal relationship between collectives and their members, the heterogeneity of social groups and non-voluntary social groups; May’s theory is problematic insofar as it relies on sameness among individual group …

Place And Food: A Relational Analysis Of Personal Food Environments, Meanings Of Place And Diet Quality, Ellen Desjardins

Theses and Dissertations (Comprehensive)

This study investigates the relational layers of meanings that people experience at places in their food environment, and how individuals express a sense of place through their collective interactions with, and understandings of, food places. It also explores the patterns of difference among these meanings of place and sense of place in terms of their potential association with dietary quality. The context of this inquiry was two-fold: first, the need identified by several population health researchers and to re-imagine place as relational and include it in the study of behavioural responses to the changing food environment; and secondly, my interest …

Individual Responsibility For Collective Harms, Melany Lorraine Banks

Theses and Dissertations (Comprehensive)

The aim of the dissertation is to propose a new theory of collective responsibility that will be able to determine individual responsibility for collective harms from small collectives to large, unstructured collectives. Theories of collective responsibility seek to address the harms that are caused when agents work collectively, and then to determine where responsibility will he in such cases. In the dissertation I show that these theories cannot address large, unstructured harms while being reducible to the individual. The key case for this dissertation is climate change, and I propose a theory of collective responsibility that will both identify this …

It’S Like Jumping Out Of A Plane Without A Parachute: Incarceration And Reintegration Experiences Of Provincially Sentenced Women In Atlantic Canada, Jennifer Robena Bernier

Theses and Dissertations (Comprehensive)

Women are now the fastest rising prison population in the world (Balfour & Comack, 2006). As more and more women are being incarcerated, it becomes increasingly important to understand how they experience imprisonment, as well as their transition back to the community. Scholarly work on women’s incarceration and reintegration is limited. In Canada, the majority of research on reintegration, and otherwise, has focused on the federal correctional system. The goal of this study was to gain a greater understanding of the incarceration and reintegration experiences of women in the provincial correctional system. In order to achieve this goal, I conducted …

What The Body Stories Of Girls Tell Us About Autonomy And Connection During Adolescence, Colleen Mcmillan

Theses and Dissertations (Comprehensive)

This qualitative study aimed to understand what the body stories of girls who exhibit signs of disordered eating reveal about the concepts of autonomy and connection during early adolescence. The study was guided by the research question “Are the symptoms of disordered eating one of the ways the female body “talks” about the experience of disconnection during adolescence?” Informed by Relational Cultural Theory, data was collected from two focus groups of 16 adolescent girls aged 11 to 14 years. Each group met six times over a four month period. Because many aspects of lived experience cannot be expressed verbally, the …
