The Role of Experience in the Organization and Refinement of Face Space

Adults code faces in reference to category-specific norms that represent the different face categories encountered in the environment (e.g., race, age). Reliance on such norm-based coding appears to aid recognition, but few studies have examined the development of separable prototypes and the way in which experience influences the refinement of the coding dimensions associated with different face categories. The present dissertation was thus designed to investigate the organization and refinement of face space and the role of experience in shaping sensitivity to its underlying dimensions. In Study 1, I demonstrated that face space is organized with regard to norms that reflect face categories that are both visually and socially distinct. These results provide an indication of the types of category-specific prototypes that can conceivably exist in face space. Study 2 was designed to investigate whether children rely on category-specific prototypes and the extent to which experience facilitates the development of separable norms. I demonstrated that unlike adults and older children, 5-year-olds rely on a relatively undifferentiated face space, even for categories with which they receive ample experience. These results suggest that the dimensions of face space undergo significant refinement throughout childhood; 5 years of experience with a face category is not sufficient to facilitate the development of separable norms. In Studies 3 through 5, I examined how early and continuous exposure to young adult faces may optimize the face processing system for the dimensions of young relative to older adult faces. In Study 3, I found evidence for a young adult bias in attentional allocation among young and older adults. However, whereas young adults showed an own-age recognition advantage, older adults exhibited comparable recognition for young and older faces. These results suggest that despite the significant experience that older adults have with older faces, the early and continuous exposure they received with young faces continues to influence their recognition, perhaps because face space is optimized for young faces. In Studies 4 and 5, I examined whether sensitivity to deviations from the norm is superior for young relative to older adult faces. I used normality/attractiveness judgments as a measure of this sensitivity; to examine whether biases were specific to norm-based coding, I asked participants to discriminate between the same faces. Both young and older adults were more accurate when tested with young relative to older faces—but only when judging normality. Like adults, 3- and 7-year-olds were more accurate in judging the attractiveness of young faces; however, unlike adults, this bias extended to the discrimination task. Thus by 3 years of age children are more sensitive to differences among young relative to older faces, suggesting that young children's perceptual system is more finely tuned for young than older adult faces. Collectively, the results of this dissertation help elucidate the development of category-specific norms and clarify the role of experience in shaping sensitivity to the dimensions of face space.

An Examination of the Development of Online Higher Education in Canada and China: Keeping Pace and Making Space

This study examined the similarities and differences that currently exist between Chinese and Canadian online higher education, and explored the economic, political, and sociocultural environments that have shaped online education in these two jurisdictions. Furthermore, this paper discussed the efficacy of, and potential for, future development of online learning in higher education in both Canada and China. The research employed a collective case study design to gather information and data on the development of online higher education. The analysis on Contact North in Canada and the One-Man University in China provide a comparative perspective on the development of 2 typical online higher educational institutions in these two countries. The study revealed that the development of online higher education is influenced by the economic, political, and sociocultural factors of environment. Contact North and the One-Man University share similarities in many aspects, but are characteristically different. The Contact North can set an example for establishing and operating a self-regulated MOOCs platform. The study also generated implications for both organizations.

Living in the Skin That I Am: An Organizational Autoethnography of an Adult Educator's Plight to Survive the Stigma of Invisible and Episodic Disability in an Academy of Administritiva

Through the reflective lens of an adult educator with invisible and episodic disabilities, this paper has been written as an organizational autoethnography. Through a process of autoethnographical sensemaking, it is intended to illuminate important gaps in organizational theory. Feminist/relational care ethics, critical reflection, and transformative learning serve as the educational theories that comprise its framework. In telling my story, embodied writing and performance narrative are used to convey the felt existence of a body exposed through words—where my “abled” and “disabled” professional teaching and learning identities may be studied against the backdrop of organizational policies and procedures. Words used to describe unfamiliar experiences and situations shape meaning for which new meaning may emerge. At the conclusion of this paper, an alternative frame of reference—a view from the margins—may be offered to articulate authenticity in the expectancy of workplace equity for adult educators with disabilities. Taken collectively on a larger level, it is hoped that this research may provide a source of inspiration for systemic organizational change in adult learning environments.

Relationship Building with Aboriginal Elders in the Publicly Funded Secondary School Classroom: A Study of Ethical Space from an Aboriginal Persepective

This is a current story of ethical space in education that is often neglected in the design of educational experiences for Aboriginal students. This story is told through an Aboriginal lens rooted in the structured Two Row Wampum Belt relational agreement between Aboriginal peoples and Settlers. Through ethnographic narrative based on an extensive literature review, individual in-depth interviews, and a personal journal, this study documents the processes of acceptance, silence, complications, and then rejection to position Aboriginal Elders as inclusive bodies of knowledge in publicly funded secondary school classrooms. Aboriginal Elders are valued as Knowledge Holders, as Aboriginal teachers, guides, and mentors. Yet, the complexities of colonial rights, politics, and policies continue to intrude deeply into the lives of Aboriginal peoples to cause silence, confusion, and struggle rather than an evolution of new knowledge amongst two co-existing solitudes under the original terms of the Two Row Wampum Belt. The study was delayed and then came to an end when the school boards and local schools scrutinized its operating policies and unresolved funding issues. This study demonstrated that despite the Two Row Wampum Belt agreement that promised a co- existent relationship between Aboriginal peoples and Settlers, the strategy of inviting Aboriginal Elders to work alongside teachers in the classroom was viewed as being in conflict with the Settler’s institutional/educational objectivities, and, as such, was denied to Aboriginal students.

Educational Leadership: Exploring the Influence of Managed and Living Systems in Educational Leadership Discourse

A conceptual analysis of educational leadership explored the influence of managed and living systems on 21st century leadership discourse. Drawing on a detailed understanding of managed and living systems theory compiled from the work of Capra (2002), Morgan (1997), Mitchell and Sackney (2009), and Wheatley (2007), this study draws attention to the managed systems systemic concepts of efficiency, control, and standardization, and the living systems concepts of collaboration, shared meaning, change, and interconnection as markers of systems theory that find resonance within leadership literature. Using these systemic concepts as a framework, this study provides important insights into the espousal of managed and living systems concepts within the leadership discourse.

Leisure as a Facilitator of Posttraumatic Growth in Individuals Living with Cancer

Although there is a growing body of literature that shifts the focus of chronic illness and trauma research to personal growth, there is limited literature on the role that leisure has in this process (e.g., Tedeschi & Calhoun, 2004). This qualitative study explored the role of leisure in the phenomenon of posttraumatic growth (PTG) for individuals living with cancer. The findings revealed that leisure influences PTG in four domains: (a) building meaningful relationships, (b) providing experiences to develop and maintain a sense of self, (c) creating opportunities to experience positive emotions, and (d) finding purpose in life. Findings provide insight on how individuals living with cancer perceive the role that leisure has in facilitating positive change after diagnosis. These findings will better enable healthcare and leisure providers to understand the unique needs of individuals living with cancer, and help them to facilitate meaningful leisure programs to encourage PTG.

Soil-Transmitted Helminths, Poverty, and Malnutrition in Honduran Children Living in Remote Rural Communities

Soil-transmitted helminth (STH) infections are endemic in Honduras, but their prevalence according to the levels of poverty in the population has not been examined. The present cross-sectional study is aimed to determine the role of different levels of poverty in STH prevalence and infection intensity as well as the potential associations of STH infections with malnutrition and anemia. Research participants were children attending a medical brigade serving remote communities in Northern Honduras in June 2014. Demographic data were obtained, and poverty levels were determined using the unsatisfied basic needs method. STH infections were investigated by the Kato-Katz method; hemoglobin concentrations were determined with the HemoCue system; and stunting, thinness, and underweight were determined by anthropometry. Data were analyzed using descriptive statistics and univariate and multivariable logistic regression models. Among 130 children who participated in this study, a high prevalence (69.2%) of parasitism was found and the poorest children were significantly more infected than those living in less poor communities (79.6% vs. 61.8%; P = 0.030). Prevalence rates of Trichuris trichiura, Ascaris lumbricoides, and hookworms were 69.2%, 12.3%, and 3.85%, respectively. In total, 69% of children had anemia and 30% were stunted. Households’ earthen floor and lack of latrines were associated with infection. Greater efforts should be made to reduce STH prevalence and improve overall childhood health, in particular, among the poorest children lacking the basic necessities of life.

Les maux de ventre des enfants haïtiens de Montréal : entre la recomposition culturelle et la souffrance familiale

Le mal de ventre chez les enfants est un lieu de métissage et de créolisation traversé par des dimensions sociales et culturelles. Il est construit collectivement au sein des familles nucléaires avec leurs parcours migratoires et leurs souffrances. Par le biais d’entretiens menés auprès de familles haïtiennes vivant à Montréal, nous documentons les trajectoires de ces douleurs, dans lesquelles les perceptions, les explications et les moyens mis en œuvre pour les soulager interagissent d’une manière dynamique. En général, les enfants perçoivent leurs maux de ventre comme une expérience insaisissable, diffuse et ayant un impact sur leur vie sociale, tout en étant tolérés par les enfants et par les mères. Ces familles n’ont pas reçu de diagnostic médical et elles attribuent à ces maux des explications provisoires en constante recomposition. En général, elles ont recours à différentes méthodes de prise en charge des maux de ventre. L’espace familial, les activités réalisées au sein des églises et la médecine officielle sont des espaces thérapeutiques privilégiés.
