Families with Children with Autism, Developmental Delay, and Typical Development: The Relationships of Parenting Self-Efficacy, Parenting Strategies, and Child Problem Behaviour

Parents of children with autism spectrum disorders (ASD) and developmental delays (DD) may experience more child problem behaviours, report lower parenting selfefficacy (PSE), and be more reactive than proactive in their parenting strategies than those who have children with typical development (TD). Differences in PSE and parenting strategies may also influence the extent to which child problem behaviours are experienced by parents who have children with ASD and DD, compared to those who have children with TD. Using a convenience sample of parents of children with ASD (n = 48), DD (n = 51), and TD (n = 72), this study examined group differences on three key variables: PSE, parenting strategies, and child problem behaviour. Results indicated that those in the DD group scored lower on PSE in preventing child problem behaviour than the ASD group. The TD group used fewer reactive strategies than the DD group, and fewer proactive strategies than both the ASD and DD groups. For the overall sample, higher reactive strategies use was found to predict higher ratings of child problem behaviour, while a greater proportion of proactive to reactive strategies use predicted lower ratings of child problem behaviour. PSE was found to moderate DD diagnosis and child problem behaviour. Implications for a behavioural (i.e., parenting strategies) or cognitive (i.e., PSE) approach to parenting are discussed.

Conceptual Analysis of Web 2.0 Technology Use to Enhance Parent–School Relationships

Parent–school relationships contribute significantly to the quality of students’ education. The Internet, in turn, has started to influence individuals’ way social communication and most school boards in Ontario now use the Internet to communicate with parents, which helps build parent–school relationships. This project comprised a conceptual analysis of how the Internet enhances parent–school relationships to support Ontario school board administrators seeking to implement such technology. The study’s literature review identified the links between Web 2.0 technology, parent–school relationships, and effective parent engagement. A conceptual framework of the features of Web 2.0 tools that promote social interaction was developed and used to analyze websites of three Ontario school boards. The analysis revealed that school board websites used static features such as email, newsletters, and announcements for communication and did not provide access to parents for providing feedback through Web 2.0 features such as instant messaging. General recommendations were made so that school board administrators have the opportunity to implement changes in their school community with feasible modifications. Overall, Web 2.0-based technologies such as interactive communication tools and social media hold the most promise for enhancing parent–school relationships because they can help not only overcome barriers of time and distance, but also improve the parents’ desire to be engaged in children’s education experiences.

Investigation into the relationships between molecular chaperones, mitochondrial antioxidant enzymes, and endothermic vertebrate longevity

The maximum lifespan (MLSP) of endothermic vertebrates can range from as little as a year to over two centuries, yet the underlying phenotype of aging is very similar amongst this group of organisms. One organelle that may be important in the phenotype of aging is the mitochondrion. When damaged, this organelle is thought to contribute to many of the neurodegenerative diseases of aging. For this thesis, mitochondria from brain tissues of 7 mammalian and 2 avian species were isolated to assess whether the antioxidant glutathione system and major molecular chaperone, HSP60, is correlated to species MLSP. Furthermore, HSP60, and the major endoplasmic reticulum chaperone, GRP78, were measured under basal conditions, and following the introduction of an oxidative stress (hydrogen peroxide) in cultured mammalian myoblasts from 10 different species. My results indicate that the enzymes involved in the glutathione defense system are not correlated to species MLSP in brain mitochondria; however HSP60 levels are indeed higher in the longer-lived species. HSP60 levels are also higher at the basal level in cultured mammalian myoblasts and after 1 hour of hydrogen peroxide exposure. GRP78 induction is not correlated to species MLSP at the basal level or following hydrogen peroxide exposure. Therefore, these results suggest that HSP60 is a correlate of longevity in endothermic vertebrate species, but neither the glutathione antioxidant defense system, nor GRP78, correlates to species longevity.

Correlation Among Math Anxiety, Attitudes Toward Math, and Math Achievement in Grade 9 Students: Relationships Across Gender

This research evaluated (a) the correlation between math anxiety, math attitudes, and achievement in math and (b) comparison among these variables in terms of gender among grade 9 students in a high school located in southern Ontario. Data were compiled from participant responses to the Attitudes Toward Math Inventory (ATMI) and the Math Anxiety Rating Scale for Adolescents (MARS-A), and achievement data were gathered from participants’ grade 9 academic math course marks and the EQAO Grade 9 Assessment of Mathematics. Nonparametric tests were conducted to determine whether there were relationships between the variables and to explore whether gender differences in anxiety, attitudes, and achievement existed for this sample. Results indicated that math anxiety was not related to math achievement but was a strong correlate of attitudes toward math. A strong positive relationship was found between math attitudes and achievement in math. Specifically, self-confidence in math, enjoyment of math, value of math, and motivation were all positive correlates of achievement in math. Also, results for gender comparisons were nonsignificant, indicating that gender differences in math anxiety, math attitudes, and math achievement scores were not prevalent in this group of grade 9 students. Therefore, attitudes toward math were considered to be a stronger predictor of performance than math anxiety or gender for this group.

The Cenozoic Gonyaulacacean Dinoflagellate Genera Operculodinium Wall, 1967 and Protoceratium Bergh, 1881 and Their Phylogenetic Relationships

The palynology of Ocean Drilling Program Site 1007, leeward of the present Bahamas Bank, provides insights into upper Oligocene–lower Pleistocene dinoflagellate cyst associations in the tropical Americas. These associations are reviewed along with the sedimentary paleoenvironment to provide context for a morphological study of the cystdefined dinoflagellate Operculodinium bahamense and its comparison with the thecadefined dinoflagellate Protoceratium reticulatum which produces a cyst assignable to the cyst-defined genus Operculodinium. Detailed reconstructions of the tabulation in both species reveal strong similarities, having a sexiform hyposomal tabulation and L-type or modified L-type ventral organization. Protoceratium reticulatum has dextral torsion of the hypotheca, requiring assignation of the genus to the subfamily Cribroperidinioideae, whereas Operculodinium bahamense has neutral torsion requiring assignation to the subfamily Leptodinioideae. Results either imply polyphyletic origins for the genus Operculodinium or that combinations of ventral organization and torsion cannot always be applied rigidly to subdivide the family Gonyaulacaceae.

Investigating the Relationships Between Teacher Identity Norms and Collaboration

The purpose of this study was to investigate how teacher identity norms relate to teacher collaboration among the practices of elementary teachers in Ontario. Using quantitative research methods, the data indicated two clusters of teacher identity norms. The norm cluster of innovation, interdependence, and cooperation showed positive correlations with collaboration and the norm cluster of conservatism, individualism, and competition showed negative correlations with collaboration. The two clusters of norms also correlated with each other. The data showed that teachers highly valued collaboration as part of their teaching practice but did not always experience it in their school setting. The analysis suggested that if schools reinforce norms of innovation, interdependence, and cooperation, collaboration will be nurtured. Further, the data showed that if norms of conservatism, individualism, and competition are continued in school cultures, then collaboration will not be sustained. As a broad educational reform agenda, teacher collaboration is used (a) to support school cultures, (b) to change teaching practices, and (c) to implement policy-based initiatives. This research is expected to benefit teachers in its capacity to inform policy makers concerning the highly complex nature of teacher collaboration and some of the factors that impact it. With an understanding of the relationships between teacher identity norms and collaboration, it may be possible for policy makers to provide appropriate support structures that reinforce collaboration in teachers' practices as well as predict potential levels of collaboration within school cultures.

Associate-Candidate Relationships: A Study of Teacher Education Field Experiences

Past research has identified the importance of the relationship between teacher candidates and their associate teachers during field experiences. Through the research questions that framed the study, I sought to contribute to a growing understanding of how the associate teacher-teacher candidate relationship develops from the perspective of teacher candidates. Using an interpretive lens, I explored the associate teacher-teacher candidate relationships of 5 teacher candidates at a mid-sized university in Southern Ontario. In this instrumental multicase study, the 5 participants described 13 pairs of relationships with associate teachers who modeled varying practices. The qualitative data surrounding these case relationships were collected through a focus group and semistructured interviews. Participants’ responses were analyzed using axial coding and constant comparative analysis. Participants identified feedback, guidance, support, genuine interactions, and relationship dynamics as central to successful field experiences. Participants also suggested that associate teachers might be better supported in their role if they were offered increased professional development from the faculties of education that organize the field experiences. The findings documented offer a fresh perspective of the role of the associate teacher in successful teacher education programs, particularly as experienced by the 5 participants.

Social competence following mild head injury and moderate traumatic brain injury: Investigating the neuropsychological relationships between arousal, social decision-making and depression

Client-directed long-term rehabilitative goals and life satisfaction following head injury emphasize the importance of social inclusion, rather than cognitive or physical, outcomes. However, very little research has explored the socio-emotional factors that pose as barriers to social reintegration following injury. This study investigates social barriers following head injury (i.e., decision-making - Iowa Gambling Task [IGT] and mood – depression) and possible amelioration of those challenges (through treatment) in both highly functioning university students with and without mild head injury (MHI) and in individuals with moderate traumatic brain injury (TBI). An arousal manipulation using emotionally evocative stimuli was introduced to manipulate the subject’s physiological arousal state. Seventy-five university students (37.6% reporting a MHI) and 11 patients with documented moderate TBI were recruited to participate in this quasi-experimental study. Those with head injury were found to be physiologically underaroused (on measures of electrodermal activation [EDA] and pulse) and were less sensitive to the negative effects of punishment (i.e., losses) in the gambling task than those without head injury, with greater impairment being observed for the moderate TBI group. The arousal manipulation, while effective, was not able to maintain a higher state of arousal in the injury groups across trials (i.e., their arousal state returned to pre-manipulation levels more quickly than their non-injured cohort), and, subsequently, a performance improvement was not observed on the IGT. Lastly, head injury was found to contribute to the relationship between IGT performance and depressive symptom acknowledgment and mood status in persons with head injury. This study indicates the possible important role of physiological arousal on socio- emotional behaviours (decision-making, mood) in persons with even mild, non-complicated head injuries and across the injury severity continuum.

The Conceptualization and Exploration of Place Allegiance: Towards a Unified Model of Person-Place Relationships within Outdoor Recreation

The academic study of place has been generally defined by two distinct and highly refined discourses within outdoor recreation research: place attachment and sense of place. Place attachment generally describes the intensity of the place relationship, whereas sense of place approaches place from a more holistic and intimate orientation. This study bridges these two methodological and theoretical separate areas of place research together by re-conceptualizing the way in which place relationships are viewed within outdoor recreation research. The Psychological Continuum Model is used to extend the language of place attachment to incorporate more of the philosophy of sense of place while attending to the empirical strength and utility of place attachment. This extension results in the term place allegiance being coined to depict the strong and profound relationships outdoor recreationists build with their places of outdoor recreation. Using a concurrent mixed methods research design, this study explored place allegiance via an online survey (n = 437) and thirteen in-depth qualitative interviews with outdoor recreationists. Results indicate that place allegiance can be measured through a multi-dimensional model of place allegiance that incorporates behaviours, importance, resistance, knowledge and symbolic value. In addition, place allegiance was found to be related to an individual's influence on life course and his/her willingness to exhibit preservation and protection tendencies. Place allegiance plays an important role in acknowledging the importance of authentic place relationships in an effort to confront placelessness. Wilderness recreation is an important avenue for outdoor recreationists to build strong place relationships.

Affect, ontology, and pedagogy: An autoethnographic study on student-teacher relationships

In studying affect within the realm of student-teacher relationships my thesis project use the concept of “affect” as composed by Baruch Spinoza (1992, 2007). I focus specifically on how Deleuze (1988) interprets and implements the term within his own philosophy, as well as on Antonio Negri’s (2011, 1991) work on Spinoza including his and Michael Hardt’s (2000, 2004, 2009) more recent works. This thesis will explore Spinoza’s affect within the discourse of Affective Pedagogy and Critical Pedagogy while remaining committed to a Spinoizist ontology as outlined by Deleuze (1988). I used artefacts from my past experiences as a student and teacher to produce evocative writing pieces which act as affective continuances of my past experiences as a student, student-teacher, and teacher, and the relationships of affect that composed them. This project used these artefacts and the writings they produced as sites of intensity that are carried through from traces, to evocative thresholds, to concepts, and finally into analysis.

The psychology of exclusivity

L’amitié et l’amour romantique sont, de par leur nature, des relations exclusives. Cet article suggère que l’on peut mieux comprendre la nature de l’exclusivité dont il est question en comprenant l’erreur au coeur de la vision du raisonnement pratique que je nomme « le point de vue englobant » . Selon le PVE, pour que le raisonnement pratique soit rationnel, il doit s’agir d’un processus ayant pour but de choisir la meilleure alternative possible à partir d’une perspective qui est aussi détachée et objective que possible. Quoique cette vision cherche à être neutre à l’égard des porteurs de valeurs, elle incorpore en fait un biais contre les porteurs de valeurs qui ne peuvent être appréciés qu’à partir d’une perspective qui n’est pas détachée - qui ne peuvent être appréciés, par exemple, que par les agents qui sont engagés à long terme envers les valeurs en question. Dans le contexte des relations personnelles, de tels engagements tendent à donner naissance à la sorte d’exclusivité qui caractérise l’amitié et l’amour romantique ; ils empêchent l’agent d’être impartial entre les besoins, les intérêts, etc. de la personne qui lui est chère, d’une part, et ceux des autres, d’autre part. Je suggère que dans de tels contextes les besoins et les revendications des autres personnes peuvent être réduites au silence, de la même manière que, comme le suggère John McDowell, les tentations de l’immoralité sont, pour l’agent vertueux, réduites au silence.

Luther on love and law : a historical investigation of Martin Luther's application of scriptural authority to Church and State

Cette thèse s’ouvre avec des commentaires du siècle dernier sur les opinions de Luther à propos de l’autorité du gouvernement et de l’Église, ainsi que sur la nature humaine et la fonction de la loi. Je présente ensuite où ces critiques situent Luther par rapport à la tradition scholastique et par rapport à la tradition romaine au sein de l’Église. Puis, j’explore les œuvres de Luther pour mettre en lumière ses arguments concernant l’Église, la source de son autorité, ainsi que la relation de celle-ci avec les gouvernements, autrement dit les autorités temporelles. De là, je m’intéresse à la comparaison que le réformateur fait entre la place de l’Église dans la société et celle de l’autorité temporelle. Enfin, j’analyse les écrits de Luther à propos de deux évènements concernant la construction du Royaume de Dieu et plus précisément, dans quelle mesure l’Église dépend, ou non, des autorités temporelles pour construire ce Royaume. Nous allons trouver une réponse surprenante à la question de comment l’église est indépendante de l’autorité temporelle dans l’ouvrage spécifique au royaume de Dieu. Le but de ma thèse est de répondre à certains critiques qui reprochent à Luther de s’appuyer sur l’autorité temporelle pour établir l’Église, et par conséquent de donner au temporel le contrôle sur le spirituel. Nous découvrirons que Luther tire son autorité des Écritures. Nous découvrirons aussi les conséquences que cette autorité a sur sa philosophie politique, c'est-à-dire l’importance de la soumission aux autorités gouvernantes en même temps que la libération des individus de la tyrannie d’une fausse doctrine.

Recasts, uptake and learning : effects and relationships

L’uptake est la réponse immédiate de l’apprenant suite à la rétroaction de l’enseignant (Lyster & Ranta, 1997). Cette étude investigue la relation entre l’uptake et l’apprentissage des déterminants possessifs et des questions d’anglais L2. Elle examine aussi l’effet des reformulations implicites et explicites en termes d’uptake et d’apprentissage. Deux classes intensives (ESL) de sixième année du primaire (N=53) à Montréal ont participé à cette étude. Les deux classes ont été réparties en deux groupes : reformulations explicites et reformulations implicites. L’intervention comportait des activités communicatives. Les élèves ont été testés sur les formes cibles immédiatement avant et après le traitement pédagogique en utilisant des taches orales. Les résultats ont confirmé l’effet supérieur des reformulations explicites en termes d’uptake et d’apprentissage et que l’effet des reformulations dépend de la cible. Cette étude a montré aussi que l’uptake peut faciliter l’apprentissage et que son absence n’est pas signe de manque d’apprentissage.
