Sport Commitment in Wheelchair Basketball: An Interpretive Look into the Lives of Individuals with Physical Disabilities

It is estimated that over 4.4 million people are living in Canada with a reported disability. Due to a number of risk factors associated with potential health concerns and sedentary lifestyles, it is important for people with physical disabilities to lead an active lifestyle. Recreation and leisure pursuits are a great outlet for this to take place. However, in order to gain the long terms benefits of these pursuits one must be committed to an activity. With the use of a collaborative interview method, with the Sport Commitment Model serving as the guiding framework, this study sought to find the underlying factors for continued participation for people with physical disabilities in wheelchair basketball. Through utilizing an interpretive approach it was found that enjoyment, social support, perceived ability and to some extent involvement opportunities, were the main contributors to overall commitment. Criticisms and suggestions for future research are also provided.

The Future of Physical Education in Higher Education: A Delphi Investigation

Despite the profound and widespread concern for the future of higher education physical education, there has been little systematic study on the topic. This research investigated the future by utilizing a two-round interview Delphi method. Five international experts were asked to project possible, probable, preferable and undesirable futures of the academic discipline in fifteen years time; specifically in regards to issues within the undergraduate degree programs, and the research sub-disciplines. The results of quantitative descriptive statistics and qualitative content analysis reveal an ever-changing higher education environment in the postmodern information age, which presents a complicating future for the academic discipline. The experts expressed concern that some disciplinarians will be a-futuristic and unable to operationalize the vast potential of the discipline at the institutional level, by continuing to use outdated and inappropriate frameworks of a modern era gone by.

The impact of social competence between physical activity and motor performance

Objective: To identify the association of low physical activity (PA) participation in children with various motor performances (MP) and to establish the impact of social competence (SC). Methods: Sixth grade children from PHAST study at Brock University (n=1958; 50.53% males) had MP test results from Bruininks-Oseretsky Test of Motor Proficiency, Participation Questionnaire (PQ) used for PA and Harter Social Competence Scale for self-perceived SC. Comparative tests, multiple and logistic regressions were performed. Results: Significant differences in PQ measures in MP quartiles and SCs. MP and SC are independent predictors of PA (p<.05) except with SES on free play activity, making MP not significant. Lower MP increased the odds of low total PA and organized sport participation but not for free play activities (OR~1). Higher SC reduced the risk of low participation in all PA measures. Conclusions: SC improves PA participation, including free play and organized sports, despite the child’s MP.

Daily Physical Activity as an Intervention Strategy for Anxious Elementary Students

The focus of this project was twofold: a comprehensive examination of provincially mandated, school-based physical activity programming beyond physical education, as well as an exploration of the potential relationship between school-based physical activity and student anxiety. The data were collected using a descriptive research methodology consisting of a qualitative document analysis of provincial government publications pertaining to school-based physical activity programming and the literature on the relationship between physical activity and student anxiety. The findings revealed inconsistencies between the Canadian provinces and territories in providing mandated school-based physical activity beyond physical education. It was also revealed that regular school-based physical activity has the potential to make a positive impact on students’ lives in many ways. Students are living more sedentary lives, and evidence shows that regular physical activity could prevent and treat student anxiety.

Is Pride a Vice or a Virtue? Associations to Well-Being and Physical Activity

The first objective of the present study was to determine patterns of association between authentic and hubristic fitness-related pride to outcomes of well-being and leisure-time physical activity (LTPA). A second objective was to examine motivation as a potential mediator of these relationships. Participants (N = 119) were young adults who completed self-report questionnaires at two time points separated by 4-weeks. Authentic and hubristic pride were associated with well-being and LTPA at Time 1 and Time 2. Changes in pride were associated with changes in well-being but not LTPA. Results of the mediation analyses highlight the role of more autonomous motives, specifically intrinsic motivation, as important mediators between pride and well-being. Motivation did not mediate the relationship between pride and LTPA. Overall, both authentic and hubristic pride seem to be important in the promotion of well-being More research is needed to elucidate the relationship between pride and LTPA.

Challenging Weight Loss: The Effectiveness of a 12 Week Weight Loss Challenge on Weight Loss, Physical Activity and Motivation

The objective of this study was to examine the effectiveness of a 12 week weight loss intervention in a commercial fitness centre on body mass index (BMI), moderate to vigorous physical activity (MVPA) and behavioural regulations consistent with Organismic Integration Theory (OIT, Deci & Ryan, 2002). The intervention group received weekly coaching sessions and bi-weekly seminars designed to increase MVPA and improve dietary intake. The results of the mixed model analyses of variance showed a significant within-subjects main effect for BMI (F = 3.57, p = .04). Changes in MVPA were not observed over time or between conditions. Changes in behavioural regulations congruent with OIT (Deci & Ryan, 2002) favoured the intervention condition. Study results indicate that 12 week weight loss challenges in commercial fitness centres may be effective to support the internalization process of exercise behavioural regulations but ineffective at producing sustainable weight loss or behavioural changes.

HIDING IN PLAIN SIGHT- Sustainable Physical Activity Program Development and Evaluation for Youth with Special Needs: An Evaluative Case Study

The purpose of my research was to contribute to the improvement and sustainability of the Special Needs Activity Program, and develop program implementation strategies that had practical outcomes. I conducted an evaluative case study of S.N.A.P in order to determine what a quality adapted physical activity (APA) program is, why S.N.A.P is considered a quality APA program, and what institutional policies and practices exist to support it. Data was collected via interviews, questionnaires, and observations. Data analysis involved inductive and deductive methods, and a SWOTAR evaluation. Results indicate that quality APA programs include: ‘people’, ‘environment’, and ‘expectations’; there are benefits of experiential learning; activity stations that promote creativity are valuable; several stakeholders do not know the details about S.N.A.P but recognize its value; the institution values what S.N.A.P provides, yet, there is nothing being done to sustain it. Future research should investigate the feasibility of implementing S.N.A.P in various contexts.

Understanding the Integration of Living Skills Through the Context of Health and Physical Education: A Case Study of Educators’ Experiences

The research presented is a qualitative case study of educators’ experiences in integrating living skills in the context of health and physical education (HPE). In using semi-structured interviews the study investigated HPE educators’ experiences and revealed their insights relative to three major themes; professional practice, challenges and support systems. Professional practice experiences detailed the use of progressive lesson planning, reflective and engaging activities, explicit student centered pedagogy as well as holistic teaching philosophies. Even further, the limited knowledge and awareness of living skills, conflicting teaching philosophies, competitive environments between subject areas and lack of time and accessibility were four major challenges that emerged throughout the data. Major supportive roles for HPE educators in the integration process included other educators, consultants, school administration, public health, parents, community programs and professional organizations. The study provides valuable discussion and suggestions for improvement of pedagogical practices in teaching living skills in the HPE setting.

Developing Physical Activity Habit in Schools for Active Lifestyle Among Children and Adolescents

This study sought to identify and suggest ways to develop physical activity habits in school-aged children and adolescents that could help them continue healthy active practices throughout their lifespan. A systematic review of the literature identified 4 key factors that may influence school-based physical activity habit formation—motivation, enjoyment, commitment, and sustainment—and how each may be achieved in schools. The research paper begins by exploring the definitions and meaning of a habit, how it is developed, and its effect on a healthy active lifestyle. The study proposes a framework comprising 3 major components (i.e., programs, teachers, students) and offers practical strategies that support and nurture the development of students’ physical activity habits in schools. The study concludes by making recommendations for further study.

Physical Activity and the Entanglement of Meaning Making for Females

This research takes a phenomenological approach through narratives to investigate the meanings females attribute to their experiences with physical activity. Nine females across the age ranges of 10-80 were asked to share three meaningful physical activity stories. These experiences could be positive or negative in nature as long as they were reflective of a meaningful experience for the participant. The aim of the research was to explore the types of physical activity experiences that females find meaningful. The results indicate that participants perceived the following to be meaningful within their experience: social support, benefits to personal health and well-being, recognition and acknowledgment, empowerment, body control, early positive experience and identity formation. Participants’ stories offered an enlightened understanding of the meanings active females associate with physical activity across their lifespans that perhaps can assist in formulating and developing strategies to encourage and promote involvement in physical activity.

Teacher-Student Rapport: Investigating its Impact on the Dropout Rate in Physical and Health Education

This study was an investigation into whether strong teacher-student rapport relates to the drop-out rates of students in grade 9 and 10 health and physical education (HPE). In the study, One hundred and thirty-six grade 9 students from five high schools in Ontario participated in this study. Findings of whether or not rapport related to students’ decision to take an additional HPE credit beyond grade 9 did not prove conclusive. A significant multivariate interaction effect was not found; however, tests of between-subject effects on sex and grade 10 dropouts showed some interesting trends. More research is needed to further illuminate the link between teacher-student rapport and students’ enrollment in optional HPE classes.

Finding and Implementing Relevant Resources in Adapted Physical Activity (APA): It's easier said than done...

The purpose of this research was to explore challenges to operationalizing and implementing relevant resources for Adapted Physical Activity (APA) and to develop a framework on how resources should be developed and implemented to foster appropriate APA. An unobtrusive methodology was used to examine existing resources and training/learning opportunities for practitioners teaching APA. Data were collected via unobtrusive methods: documents, records, literature and feedback forms. After the findings were summarized, expert consultations were completed using a modified Delphi- technique to confirm the findings. A constructivist approach and phenomenological orientation was used to analyze the data and develop the “ideal” resource. Results indicate there are limited APA resources and teaching/learning opportunities for practitioners and there is a need for practitioner facilitation through professional development on finding and implementing resources. Future research should develop and evaluate the “ideal” resource and strive to improve the connection and consistency of resources in APA.

Predicting Physical, Verbal, Social, Racial, and Sexual Bullying with Individual and Environmental Factors from an Evolutionary Ecological Framework

Evidence exists for subtypes of bullying, but there is a lack of studies simultaneously investigating the factors that influence each subtype. The purpose of my thesis was to investigate how individual and environmental factors independently and interactively predict physical, verbal, social, racial, and sexual bullying using an evolutionary ecological framework. Adolescents (N = 225, M = 14.05, SD = 1.54) completed self-reports on demographics, HEXACO personality, Rothbart’s temperament, parenting, friendship quality, school connectedness, and socio-economic status. Subtypes were predicted by low Honesty-Humility in addition to other personality and demographic factors with the exception of physical bullying, which was predicted by environmental factors. Results suggest adolescents adaptively and selectively use bullying to exploit victims and obtain resources, although the subtype used may depend on individual factors bullies possess within Bronfenbrenner’s microsystem, instead of the meso- and exo- systems. Anti-bullying efforts should target these factors and reinforce alternative strategies to obtain resources.

The Fast Regulation of Photosynthesis in Diatoms: an inquiry into the physiological and physical origins of non-photochemical chlorophyll fluorescence quenching.

Diatoms are renowned for their robust ability to perform NPQ (Non-Photochemical Quenching of chlorophyll fluorescence) as a dissipative response to heightened light stress on photosystem II, plausibly explaining their dominance over other algal groups in turbulent light environs. Their NPQ mechanism has been principally attributed to a xanthophyll cycle involving the lumenal pH regulated reversible de-epoxidation of diadinoxanthin. The principal goal of this dissertation is to reveal the physiological and physical origins and consequences of the NPQ response in diatoms during short-term transitions to excessive irradiation. The investigation involves diatom species from different originating light environs to highlight the diversity of diatom NPQ and to facilitate the detection of core mechanisms common among the diatoms as a group. A chiefly spectroscopic approach was used to investigate NPQ in diatom cells. Prime methodologies include: the real time monitoring of PSII excitation and de-excitation pathways via PAM fluorometry and pigment interconversion via transient absorbance measurements, the collection of cryogenic absorbance spectra to measure pigment energy levels, and the collection of cryogenic fluorescence spectra and room temperature picosecond time resolved fluorescence decay spectra to study excitation energy transfer and dissipation. Chemical inhibitors that target the trans-thylakoid pH gradient, the enzyme responsible for diadinoxanthin de-epoxidation, and photosynthetic electron flow were additionally used to experimentally manipulate the NPQ response. Multifaceted analyses of the NPQ responses from two previously un-photosynthetically characterised species, Nitzschia curvilineata and Navicula sp., were used to identify an excitation pressure relief ‘strategy’ for each species. Three key areas of NPQ were examined: (i) the NPQ activation/deactivation processes, (ii) how NPQ affects the collection, dissipation, and usage of absorbed light energy, and (iii) the interdependence of NPQ and photosynthetic electron flow. It was found that Nitzschia cells regulate excitation pressure via performing a high amplitude, reversible antenna based quenching which is dependent on the de-epoxidation of diadinoxanthin. In Navicula cells excitation pressure could be effectively regulated solely within the PSII reaction centre, whilst antenna based, diadinoxanthin de-epoxidation dependent quenching was implicated to be used as a supplemental, long-lasting source of excitation energy dissipation. These strategies for excitation balance were discussed in the context of resource partitioning under these species’ originating light climates. A more detailed investigation of the NPQ response in Nitzschia was used to develop a comprehensive model describing the mechanism for antenna centred non-photochemical quenching in this species. The experimental evidence was strongly supportive of a mechanism whereby: an acidic lumen triggers the diadinoxanthin de-epoxidation and protonation mediated aggregation of light harvesting complexes leading to the formation of quencher chlorophyll a-chlorophyll a dimers with short-lived excited states; quenching relaxes when a rise in lumen pH triggers the dispersal of light harvesting complex aggregates via deprotonation events and the input of diadinoxanthin. This model may also be applicable for describing antenna based NPQ in other diatom species.

Deconstructing Child Youth Care: an autoethnographic exploration of physical restraints in children’s residential settings

This thesis is written through the front-line perspective of a child/youth worker who has experienced ‘rupture’ in her personal understanding of the Child Youth Care (CYC) practice. Using a collection of personal journal entries written about her individual experiences of CYC education, mentorship/training, front-line residential practice and frequently used interventions, this thesis takes the reader (and the writer) on a discovery of prominent discourses that exist within the residential CYC profession. Focusing on the use of physical restraints on children by residential Child/Youth Workers, this research project utilizes Deconstructive Discourse Analysis and Liberation Psychologies to illustrate a critical examination of power-knowledge and scientific/medical discourses in CYC practice. By focusing on Foucault’s concepts of disciplinary power, binary division and theory of panopticism, the writer seeks to explore a personal reflection and comprehension of how power is used to assert control over children/youth through mental health treatment and physical interventions.
