Inclusionary practices prescribe that chl1dren, regardless of exceptional1ty shall benef1t from receiv1ng educational serv1ce 1n the context of the regular class sett1ng. The result1ng el1minat1on of separate spec1al classes could be v1ewed as an econom1c advantage. In point of fact, many school boards and d1str1cts 1n both Canada and the United States are mov1ng towards 1mplementat1on of inclusionary practice, possibly for the above stated reason. Regardless, 1nclusion as 1t relates to the emot1onally/behav1ourally disordered youth in our school systems may not be successful. Regular educat ion teachers may not be prepared profess1onally or personally to deal w1th this very special student population. Th1s study focused on teacher attitude 1n this regard. As well, poss1ble factors that may lead to successful 1nclusion of these students are examined. Of these, teacher exper1ence, educat10n spec1f1c to the d1sab1l1ty of emot1onal/behavioural d1sordered comb1ned w1th teacher self-perception of success appear to hold the greatest promise. In view of these findings, recommendat1ons are made for professional pract1ce and future research d1rect1ons.

Within the field of early childhood education, the ideologies of child development and its parent discipline, developmental psychology, dominate both theory and practice. In recent years, educators have attempted to reconceptualise early childhood education by adopting more progressive approaches to teaching and learning. The aim of this present research study was to critically examine the experiences of early childhood educators who have adopted a Reggioinspired approach to educating young children. To explore their experiences, an institutional ethnography was employed involving seven educators from a large child care organization in Hamilton, Ontario. In line with the intent ofthis study, qualitative data were collected through in-depth semi-structured interviews, participant-observations and textual analyses to explore the presence of developmental-psychological ideologies within early childhood education and Reggio-inspired practice. The present study also examined the challenges faced by educators who have adopted a Reggio-inspired approach. The results of this study indicate that ideologies associated with the developmental-psychological paradigm dominate the practice of early childhood educators and that the conflicting ideologies that surround Reggio educators may play a role in some of the challenges educators experience. The findings of this study thus demonstrate a need to adopt alternative approaches toward understanding both children and childhood, in both early childhood educational theory and practice.

Background: Increasing Overweight and Obesity (OwOb) prevalence in pediatric populations is becoming a public health concern in many countries. The purpose of this study was to determine if childhood stature components, particularly the Leg Length Index (LLI = [height - sitting height]! height), were useful in assessing risk of OwOb in adolescence. Methods: Data was from a longitudinal study conducted in south Ontario since 2004. Approximately 2360 students had body composition measurements including sitting height and standing height at baseline. Among them, 1167 children (573 girls, 594 boys) who had weight and height measured at the 5 th year follow-up, were included in this analysis. OwOb was defined using age and sex specific BMI (kg!m 2 ) cut-off points corresponding to adults' BMI ~ 25. Results: Overall, 34% (n=298) of adolescents were considered as OwOb. The results from logistic regression analysis indicated that with 1 unit increase in LLI the odds of OwOb decreased 24% (Odds Ratio, [95% Confidence Interval], 0.76, [0.66-0.87]) after adjusted for age, sex and baseline waist circumference. Further adjusting for birth weight, birth order, breastfeeding, child's physical activity, maternal smoking, education, mother's age at birth and mother's BMI, did not change the relationship. Our results also indicated that mother's smoking status is associated with LLI. Discussion: Although LLI measured at childhood in this study is related to OwOb risk in adolescents, the underlying mechanism is unclear and further study is needed.

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.

This study investigated parent and child perspectives of childhood cancer survivors' return to school. Four specific areas were examined including cognitive and academic concerns, social issues, perceived support, and the impact on siblings. Participants consisted of parents and childhood cancer survivors who were recruited through a regional parent support group. Data was collected during a focus group and interviews. Using a descriptive content analysis, results indicated that participants generally received the necessary resources, however issues such as consistency and having to advocate in order to attain these resources served as barriers for the families.

In challenging normative social relations, queer cultural studies has shied away from deploying historical materialist theoretical tools. My research addresses this gap by drawing these two literatures into conversation. I do so by investigating how global economic relations provide an allegorical and material context for the regulation, representation and re-imagining of working-class queer childhood through anti- capitalist queer readings of three films: Kes, Billy Elliot, and Boys Village. I deploy this reading practice to investigate how these films represent heteronormative capitalism’s systematic extermination of the life possibilities of working class children, how children resist forces of normalisation by creating queer times and spaces, and how nostalgia engenders a spatio-temporal understanding of queerness through a radical utopianism. My analysis foregrounds visual cultural productions as sites for understanding how contemporary social worlds exclude queer working class children, who struggle to insert themselves into and thereby shift the grounds of normative social relations.

Integrated Ocean Drilling Program (IODP) Site U1313, located at the northern boundary of the subtropical gyre in the central North Atlantic, lies within the southern part of the ice-rafted debris belt. Seventy-three palynological samples were studied from an uninterrupted interval ca. 726–603 ka (upper Marine Isotope Stage [MIS] 18 through lower MIS 15) to resolve conflicting paleoceanographic interpretations. Glacial stages were characterized by high productivity surface waters reflecting a southward shift of the Arctic Front. Sea surface salinities (SSSs) and sea surface temperatures (SSTs) were obtained by transfer functions using the Modern Analogue Technique. The lowest SSTs of 9ºC (±1.3) and 10ºC (±1.3) were recorded in glacial MIS 16 and MIS 18 respectively. However, these reconstructions are influenced by abundant heterotrophic taxa and may reflect elevated nutrient levels rather than lowered temperatures. Reworked palynomorphs uniquely indicate a Cretaceous as well as Paleozoic provenance for the first Heinrich-like events.

This is the first detailed study of organic-walled dinoflagellate cysts (dinocysts) and acritarchs for the latest Miocene–Middle Pleistocene of Ocean Drilling Program Site 1000 in the Caribbean Sea. Well-preserved and moderately diverse dinocysts and other palynomorphs reflect the interplay between neritic (carbonate-platform sourced) and oceanic species. The dinocyst biostratigraphy is tied to an existing marine isotope stratigraphy for the interval 5.5–2.2 Ma. For the interval 5.5–3.8 Ma, palynological samples are coupled to published sea-surface temperature estimates based on planktonic foraminiferal Mg/Ca. Changes in dinocyst assemblage composition are noted at ca. 4.6 Ma when shoaling of the Central American Seaway caused a temperature rise in the Caribbean, ca. 3.8–3.6 Ma, during the cold Marine Isotope Stage M2 when pronounced warming occurred, at ca. 2.7 Ma where possible weak cooling may reflect the onset of Northern Hemisphere glaciation, and in the Middle Pleistocene presumably reflecting global cooling and sea-level fall.

Research studies on labeling of children have either focused on the effects of formal labels on the lives of children with exceptionalities and mental health issues, or the effect of informal labeling by parents, peers and teachers on teenagers. The effects of informal labeling in childhood and its implications in later life or for one’s career choice have not yet been examined. This study adds to the growing research on informal labeling. The purpose of this qualitative study was to determine what negative effects informal labeling of children as deviant had on their lives. Data were gathered through semi-structured interviews conducted with seventeen young adults, between the ages of sixteen and thirty years, from a post-secondary institution and an organization for homeless youth. The results showed an initial negative impact on the lives of the young adults during their childhood and early teenage years but as they progressed into their late teens and early adulthood, most were able to overcome their negative labels suggesting resilience. There were no significant gender differences in the impact of the labels. The implications of the study for policy makers and parents are discussed as well as some recommendations for parents and practitioners are offered.

Some egalitarians argue against public services that are free for all, on the grounds that free access appears to primarily benefit the middle classes. I advocate, instead, the inclusion of the middle classes in public services, arguing that only truly universal intake of public services prevents the inegalitarian effects of economic segregation. Such universal participation in public services is achieved, partly, through subsidies for, and regulation of, privately produced services.

La leucémie lymphoblastique aigüe (LLA) est une maladie génétique complexe. Malgré que cette maladie hématologique soit le cancer pédiatrique le plus fréquent, ses causes demeurent inconnues. Des études antérieures ont démontrées que le risque à la LLA chez l’enfant pourrait être influencé par des gènes agissant dans le métabolisme des xénobiotiques, dans le maintient de l’intégrité génomique et dans la réponse au stress oxydatif, ainsi que par des facteurs environnementaux. Au cours de mes études doctorales, j’ai tenté de disséquer davantage les bases génétiques de la LLA de l’enfant en postulant que la susceptibilité à cette maladie serait modulée, au moins en partie, par des variants génétiques agissant dans deux voies biologiques fondamentales : le point de contrôle G1/S du cycle cellulaire et la réparation des cassures double-brin de l’ADN. En utilisant une approche unique reposant sur l’analyse d’une cohorte cas-contrôles jumelée à une cohorte de trios enfants-parents, j’ai effectué une étude d’association de type gènes/voies biologiques candidats. Ainsi, j’ai évaluer le rôle de variants provenant de la séquence promotrice de 12 gènes du cycle cellulaire et de 7 gènes de la voie de réparation de l’ADN, dans la susceptibilité à la LLA. De tels polymorphismes dans la région promotrice (pSNPs) pourraient perturber la liaison de facteurs de transcription et mener à des différences dans les niveaux d’expression des gènes pouvant influencer le risque à la maladie. En combinant différentes méthodes analytiques, j’ai évalué le rôle de différents mécanismes génétiques dans le développement de la LLA chez l’enfant. J’ai tout d’abord étudié les associations avec gènes/variants indépendants, et des essaies fonctionnels ont été effectués afin d’évaluer l’impact des pSNPs sur la liaison de facteurs de transcription et l’activité promotrice allèle-spécifique. Ces analyses ont mené à quatre publications. Il est peu probable que ces gènes de susceptibilité agissent seuls; j’ai donc utilisé une approche intégrative afin d’explorer la possibilité que plusieurs variants d’une même voie biologique ou de voies connexes puissent moduler le risque de la maladie; ces travaux ont été soumis pour publication. En outre, le développement précoce de la LLA, voir même in utero, suggère que les parents, et plus particulièrement la mère, pourraient jouer un rôle important dans le développement de cette maladie chez l’enfant. Dans une étude par simulations, j’ai évalué la performance des méthodes d’analyse existantes de détecter des effets fœto-maternels sous un design hybride trios/cas-contrôles. J’ai également investigué l’impact des effets génétiques agissant via la mère sur la susceptibilité à la LLA. Cette étude, récemment publiée, fût la première à démontrer que le risque de la leucémie chez l’enfant peut être modulé par le génotype de sa mère. En conclusions, mes études doctorales ont permis d’identifier des nouveaux gènes de susceptibilité pour la LLA pédiatrique et de mettre en évidence le rôle du cycle cellulaire et de la voie de la réparation de l’ADN dans la leucémogenèse. À terme, ces travaux permettront de mieux comprendre les bases génétiques de la LLA, et conduiront au développement d’outils cliniques qui amélioreront la détection, le diagnostique et le traitement de la leucémie chez l’enfant.

Kabazi II est un site de plein air, situé sur la deuxième rangée des Monts de Crimée. Après sa découverte en 1986, les investigations archéologiques effectuées entre 1987 et le milieu des années 90 ont établi que Kabazi II avait auparavant servi de lieu de chasse et d’abattage pour les groupes néanderthaliens de la région. Les études archéozoologiques antérieures (Patou-Mathis 2003, 1999, 2005, 2006a, 2006b) ont déterminé que les stratégies de subsistance des Néanderthaliens du Kabazi II étaient très spécialisées et principalement axées sur la chasse des petits groupes de Equus hydruntinus mais aussi, à l’occasion, sur la chasse d’autres espèces. Ces comportements ont persisté malgré les changements climatiques et technologiques à travers l’histoire d’occupation du site. Cette étude présente l’analyse des assemblages fauniques encore inédits des niveaux II/1,II/2-1, II/2, II/3, II/4, II/5, II/7, II/8, II/9, II/13, II/13A de Kabazi II. Nos résultats sont en accord avec ceux obtenus parles d’études antérieures ; cependant, des différences par rapport à la fonction du site ont été constatées et un lien possible avec Kabazi V, un abri sur roche tout près de Kabazi II, a été établi. On croit que la persistance des activités de subsistance des Néanderthaliens de Kabazi II pendant presque 100 000 ans de présence est due à la polyvalence des ânes asiatiques tels que Equus hydruntinus, au contexte géographique et géologique de la région ainsi qu’aux caractéristiques du site elles-mêmes.
