In contemporary times, there is a compelling need to understand the nature of positive community relationships that value diverse others. This dissertation is a hermeneutic phenomenological inquiry into the essence of what it means to feel a sense of community. Specifically, I explored this phenomenon from the perspective of middle school teachers and students through the following questions: What meanings do students and teachers ascribe to feeling, experiencing, and developing a sense of community in their classes? To what extent do students’ and teachers’ ideas about feeling a sense of community include the acceptance of individual differences? Together these questions contributed to the overarching question, what is the essence of feeling a sense of community? As the data pool for the research, I used 192 essays and 218 posters from students who had been asked to write or draw about their visions of a positive classroom community where they felt a sense of community. I conducted 9 teacher interviews on the topic as well. My findings revealed one overarching ontology, Being-in-Relation, which outlined a full integration between individuality and community as a “way of being.” I also found five attributes that are present when individuals feel a sense of community: Supporting Others, Dialogue, An Ethic of Respect and Care, Safety, and Healthy Conflict. Contributions from this research include extensions to the literature about community; clarity for those who wish to establish a strong foundation of community relationships within formal and non-formal educational programs; insight that may assist educators, leaders, and policy makers within formal educational systems; and an opportunity to consider the extent to which the findings may point toward broader implications.

Scientists have overwhelmingly concluded that global warming occurs as a consequence of human activities and that climate change, combined with the depletion of resources, could have catastrophic consequences for the human civilization later this century. However, in political circles and in the public sphere these conclusions are not taken seriously, or they are laid aside for future generations to deal with; at the same time, significant efforts are being deployed to discredit the scientific evidence. In this thesis I have studied the positions of climate scientists as well as those of climate change deniers, and I also examined how their points of view are likely to impact the interests and habits of corporations and citizens. The work of Thomas Homer-Dixon was used as an important source for analyzing the complex interaction between our natural, economic, and social systems, and John Dewey's pattern of inquiry provided the theoretical foundation for an analysis of the current crisis and its possible solutions. No concerted action to deal with climate change has yet been taken by the leaders of the Western world; I corroborated data from four reliable sources (Hansen, 2009; IPCC, 2007; Lynas, 2007; Steffen, 2011) regarding several development scenarios and their likely consequences on greenhouse gas emissions, and I concluded that a future temperature increase of more than 2°C appears now as unavoidable. In the light of this conclusion I argue that education for increasing the resilience of smaller communities is a realistic alternative that can offer some hope in dealing with the challenges ahead.

Parent education programs offered by a variety of public health services are effective support and knowledge resources that enhance positive parenting competencies in early childhood and adolescence. However, parenting education programs are less effective and encompass fewer benefits for fathers in comparison to mothers. This study sought to investigate trends of paternal involvement in early childhood and to compare the influence of parenting education programs on paternal involvement and conceptualization of fathers. A sample of 52 fathers, between the ages of 19 to 54, with children 6 years old and younger completed an electronic or hard copy version of a survey questionnaire reporting on their fathering and experiences as a dad. Findings indicate the sample of Canadian fathers self-reported high levels of paternal involvement, including many who favoured play-based interactions with their children. Although no significant difference in levels of involvement was noted between fathers who had versus those who had not previously participated in a parenting education program, half of the Canadian fathers indicated that supports are needed to strengthen their role as fathers. Results suggest that future initiatives to strengthen parent education program services available in Canada should specifically consider the father’s role.

This narrative study examined women’s experiences in leadership positions in an educational setting in Southern Ontario. Semi-structured interviews with 4 women (2 principals and 2 vice principals) revealed 4 key themes: (a) considerations prior to entering into leadership and confidence instilled by others to continue on that path; (b) ongoing challenge of maintaining work−life balance; (c) others’ perceptions of women in leadership positions; and (d) increasing number of women in leadership positions. The researcher used feminist standpoint theory to analyze data collected during interviews, which gave voice to the study’s participants and shed some light on women’s gendered experiences in leadership positions. Findings suggest that historical roots significantly influence society to continue with stereotypical gender roles, though some participants have overcome certain stereotypes. The literature review and participants’ experiences suggest that women have made some progress throughout history yet society needs to remain vigilant while striving for gender equality.

This narrative case study describes an English as an Additional Language teacher’s struggle to understand her young adult learners’ apparent resistance toward multiliteracies pedagogical practices in a college setting. Multiliteracies Pedagogy (New London Group, 1996) advocates the use of digital media, and home languages and culture, to engage diverse youth in designing personally meaningful multimodal texts that can significantly impact learner identity, voice, and agency. This arts-based study uses an innovative sonata-style format to document the making of a class documentary, accompanied by teacher reflections on the video project in the form of poetry, journal excerpts, and classroom dialogue. The sonata form provides a unique methodology for teacher inquiry, allowing the teacher-researcher to explore the ways in which curriculum, pedagogy, and sociocultural influences intersect in the classroom. The study does not end with a clear resolution of the problem; instead, the process of inquiry leads to deeper understandings of what it means to teach in the complex worlds of diverse learners.

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.

This mixed-methods research study sought to determine the impact of an informal science camp—the Youth Science Inquiry Development Camp (YSIDC)—on participants’ science inquiry skills, through self-assessment, as well as their views and attitudes towards science and scientific inquiry. Pre and post data were collected using quantitative surveys (SPSI, CARS), a qualitative survey (VOSI-E), interviews, and researcher’s observations. Paired sample t-tests from the quantitative surveys revealed that the YSIDC positively impacted participants’ science inquiry skills and attitudes towards science. Interviews supported these findings and provided contextual reasons for these impacts. Implications from this research would suggest that informal and formal educational institutions can increase science inquiry skills and promote positive views and attitudes towards science and scientific inquiry by using non-competitive cooperative learning strategies with a mixture of guided and open inquiry. Suggested directions for further research include measuring science inquiry skills directly and conducting longitudinal studies to determine the lasting effects of informal and formal science programs.

Epilepsy is a chronic neurological disorder characterized by recurrent seizures (Stein & Kanner, 2009). The purpose of this study was to understand the essence of being a young woman living with epilepsy using heuristic inquiry (Moustakas, 1990). The research was built upon the assumption that each experience is unique, yet commonalities exist. Five women aged 22 to 28 years living with epilepsy were interviewed. Additionally, the researcher described her life with epilepsy. Participants characterized life with epilepsy as a transformative journey. The act of meeting and interacting with another woman living with epilepsy provided an opportunity to remove themselves from the shadows and discuss epilepsy. Three major themes of seizures, medical treatment, and social relationships were developed revealing a complex view of an illness requiring engaged advocacy in the medical system. Respondents frequently make difficult adjustments to accommodate epilepsy. This study provides a complex in-depth view of life with epilepsy.
