The link between extracurricular activities and academic achievement for youth in grades 5 and 7 /

This study examined the link between involvement in extracurricular activities and academic success for 504 youth in grades 5 and 7, using the first-year survey data from a longitudinal study conducted by Youth Lifestyle Choices-Community University Research Alliance (YLC-CURA). Specifically, the study investigated whether a linear or curvilinear relation existed between extracurricular activities and academic achievement for both in- and out-of-school activities. It was hypothesized that stress may be a possible mediator in the link between extracurricular activities and achievement Results indicated that students in grades 5 and 7 were involved in club and sport activities both inside and outside of school at fairly equal fi-equencies, with a mean frequency of approximately once a month. The hypothesis that a positive relation j between in- and out-of-school extracurricular activities and achievement was supported. The hypothesis that a curvilinear relation would exist between extracurricular activities and achievement was only supported for out-of-school activities. This finding supports the argument that too much or too little involvement in out-of-school activities is related negatively to a student's academic success; however, a moderate amount of involvement appears to be positive. The hypothesis that there would be a relation between involvement in extracurricular activities and stress level for both in-school and out-ofschool activities was not supported. Results were discussed in terms of educational implications and community resources for extracurricular activities.

Longitudinal associations between passions and adjustment in adolescence: Positive mood and unstructured leisure activities as mediators

Passions are activities that people find important, like or enjoy, and on which they spend large amounts of time. Research examining passions in adolescence has been limited, despite a tendency for adolescents to explore their identity by trying new activities (Dworkin et aI., 2003). The purpose of the present study was to examine the association between adolescent passions and positive adjustment (psychological well-being, optimism, purpose in life, and low risktaking), as well as investigate possible underlying mechanisms for the link between passions and adjustment. High school students (N=2270, 48.7% female) from Southern Ontario completed questionnaires in grades 10, 11, and 12. Path analyses were conducted to examine cross-lag paths among all study variables. Passions predicted higher optimism and purpose, as well as lower negative risk-taking, over time, but these adjustment indicators in tum did not predict higher passions over time. Additionally, positive mood and unstructured leisure activities partially mediated these associations. Passions appears to be important for adolescent adjustment, and may serve as a protective factor or help to foster thriving.

Community Recreation and Leisure Activities in Adults with Developmental Disabilities who have Recently Relocated to Community-based Residences in Ontario

In 2009, the Ontario Government closed the last three remaining large-scale institutions for people with Developmental Disabilities (DD). The purpose of this study is to examine the community-based recreation and leisure activities of 87 adults with DD who have recently moved into the community. Study 1 provided a descriptive insight into the community recreation and leisure activities, and revealed that people with DD engage in low levels of community activities, however are reported to have the desire to engage more often. Staff reported that people with DD do not have the opportunities to engage in their preferable activities. Study 2 investigated the prbspective predictors of the number and frequency of community, recreation and leisure activities and found that a higher level of functioning predicted a greater number of community activities ([beta] = .26, P < .05), while both a higher level of functioning ([beta] = .38,p < .001) and greater preference ([beta] = .23. p < .05) predicted more frequent access to community activities. Future research and the implications of the findings for clinical practice and policy development were discussed.

Promoting Early Reading: A Parent Handbook for Developing Children's Phonological Awareness Using Authentic Activities

The purpose of this project was to create a handbook for parents to develop their children's phonological awareness using authentic activities that parents and children can complete together. The handbook aims to provide parents with fundamental background information regarding phonological awareness as well as effective instruction practices, followed by authentic activities that are clearly laid out and easy to implement. Through a comprehensive study of the literature it became evident that parents should be the target audience for the handbook as they have the greatest influence on the development of their young children. Phonological awareness was also found to be an important contributor to early literacy development including oral language skills and reading. The handbook was reviewed by 2 teaching professionals in order to claim face validity of the document. The results of the project indicate that the handbook which was produced meets its goals of creating a product that is easy to use, practical, and effective for both parents and children. The implementation of the handbook in the home environment can benefit children's phonological awareness and in turn improve their oral language and reading abilities.

The effect of synchronized group activities on pain threshold as a predictor of cooperation

Recent research suggests that participating in vigorous synchronized physical activity may result in elevated levels of endorphins, which may in turn affect social bonding (Cohen et. al., 2009). The present research aimed to examine whether or not the change in pain tolerance would be able to predict participants’ willingness to cooperate after statistically controlling for the groups’ condition. Participants were asked to run on a treadmill for 30 minutes under one of two conditions (control vs. synchronized). Prior to and after the run participants underwent a pain tolerance test. Once completed, a second activity was introduced to the participants; a cooperative game. A public goods game was used to measure an individual’s willingness to cooperate. The results showed the synchronized condition was able to predict that participants cooperated more during the public goods game (p = .009), however the change in pain threshold was unable to significantly predict cooperation (p = .32).

Benefits of Using Target Activities to Assist in Improvement of Striking in Striking and Fielding Games for Individuals with Autism: A Comparative Case Study

The purpose of the research study was to increase understanding about the potential benefits of combining target activities with striking-fielding games for individuals with high functioning autism spectrum disorder. A comparative case study was conducted to understand if target activities can assist in improving the skills of striking and throwing, aid the learning of tactics and add to current understanding of how certain teaching skills might be linked to the transfer between target and striking-fielding games. Data was collected through observations, student journals and interviews and were analyzed using both inductive and deductive methods. Results show an appearance of improvement in throwing, striking, bowling and badminton for overall skill levels. In regards to teaching skills, appropriate and effective teaching techniques, appropriate and effective equipment, dynamic of participants and student-instructors and consistency of attendance are vital. Future research should further look at the transferability to outdoor settings and interview the participants.

Mindfulness Practices and Children’s Emotional and Mental Well-Being: Activities to Build and Strengthen Everyday Resilience Adapted for Primary School Teachers

This project reviewed current research on mental health and Canadian children, and then examined the practice of mindfulness as a means of supporting well-being and circumventing the potential detrimental effects of mental health problems. By contextualizing these findings within the recently released educational vision of the Ontario Ministry of Education (2014), which identifies well-being as one of the core principles of education in Ontario, this project investigated how mindfulness-based practices can be brought into the primary grade classroom. The ultimate purpose of this project is the development of a handbook for Ontario teachers of students in grades 1 to 3 (ages 6 to 8). This resource was developed from a comprehensive literature review and provides educators with easy-to-follow activities to use in the classroom to encourage the development of resilience and emotional well-being through mindfulness. The handbook also includes additional information and resources regarding both mindfulness and mental health that may be helpful to teachers, students, and parents.

Organizational Design of R&D Activities

This paper addresses the question of whether R&D should be carried out by an independent research unit or be produced in-house by the firm marketing the innovation. We define two organizational structures. In an integrated structure, the firm that markets the innovation also carries out and finances research leading to the innovation. In an independent structure, the firm that markets the innovation buys it from an independent research unit which is financed externally. We compare the two structures under the assumption that the research unit has some private information about the real cost of developing the new product. When development costs are negatively correlated with revenues from the innovation, the integrated structure dominates. The independent structure dominates in the opposite case.

Association between independence in daily activities and social roles in older adults with stroke

La réadaptation des personnes âgées ayant subi un accident vasculaire cérébral vise à améliorer les capacités et l’indépendance dans les activités de la vie courante. Les personnes âgées reprennent leurs rôles sociaux lorsqu’elles retournent vivre dans la communauté. L’objectif de ce mémoire est de clarifier la relation entre l’indépendance dans les activités de la vie courante au congé de la réadaptation intensive et la reprise des rôles sociaux six mois plus tard. L’échantillon se compose de 111 participants recrutés au congé et réévalués 6 mois plus tard. L’indépendance dans les activités de la vie courante est mesurée avec les sections pertinentes du Système de Mesure de l’Autonomie Fonctionnelle (SMAF). Les rôles sociaux sont mesurés avec la Mesure des Habitudes de Vie (MHAVIE); un score total ainsi que 4 sous-scores pour les responsabilités civiles, la vie communautaire, les relations interpersonnelles et les loisirs sont générés. Des analyses de régression hiérarchique sont utilisées pour vérifier l’association entre les activités de la vie courantes (variable indépendante) et les rôles sociaux (variables dépendante) tout en contrôlant pour les capacités (variables de contrôle). Les résultats suggèrent des associations significatives (p < .001) entre les activités de la vie courante et les rôles sociaux (score total de la MHAVIE), les sous scores des responsabilités civiles et de la vie communautaire, mais aucune association avec les relations interpersonnelles et les loisirs. Les scores les plus faibles sont obtenus pour les loisirs. Une deuxième phase de réadaptation après le retour à domicile pourrait permettre le développement des loisirs.

Managing Antimicrobial Resistance In Food Production : Conflicts Of Interest And Politics In The Development Of Public Health Policy

Antimicrobial resistance is a growing public health concern and is associated with the over or inappropriate use of antimicrobials in both humans and agriculture. While there has been recognition of this problem on the part of agricultural and public health authorities, there has nonetheless been significant difficulty in translating policy recommendations into practical guidelines. In this paper, we examine the process of public health policy development in Quebec agriculture, with a focus on the case of pork production and the role of food animal veterinarians in policy making. We argue that a tendency to employ strictly techno-scientific risk analyses of antimicrobial use ignores the fundamental social, economic and political realities of key stakeholders and so limits the applicability of policy recommendations developed by government advisory groups. In particular, we suggest that veterinarians’ personal and professional interests, and their ethical norms of practice, are key factors to both the problem of and the solution to the current over-reliance on antimicrobials in food production.

POCN-type Pincer Complexes of NiII and NiIII : synthesis, reactivities, catalytic activities and physical properties

Cette thèse décrit la synthèse, la caractérisation, les réactivités, et les propriétés physiques de complexes divalents et trivalents de Ni formés à partir de nouveaux ligands «pincer» de type POCN. Les ligands POCN de type amine sont préparés d’une façon simple et efficace via l’amination réductrice de 3-hydroxybenzaldéhyde avec NaBH4 et plusieurs amines, suivie par la phosphination de l’amino alcool résultant pour installer la fonction phosphinite (OPR2); le ligand POCN de type imine 1,3-(i-Pr)2PC6H4C(H)=N(CH2Ph) est préparé de façon similaire en faisant usage de PhCH2NH2 en l’absence de NaBH4. La réaction de ces ligands «pincer» de type POCN avec NiBr2(CH3CN)x en présence d’une base résulte en un bon rendement de la cyclométalation du lien C-H situé en ortho aux fonctions amine et phosphinite. Il fut découvert que la base est essentielle pour la propreté et le haut rendement de la formation des complexes «pincer» désirés. Nous avons préparé des complexes «pincer» plan- carrés de type POCN, (POCNRR΄)NiBr, possédant des fonctions amines secondaires et tertiaires qui démontrent des réactivités différentes selon les substituants R et R΄. Par exemple, les complexes possédant des fonctions amines tertiaires ArCH2NR2 (NR2= NMe2, NEt2, and morpholinyl) démontrent des propriétés rédox intéressantes et pourraient être convertis en leurs analogues trivalents (POCNR2)NiBr2 lorsque réagis avec Br2 ou N-bromosuccinimide (NBS). Les complexes trivalents paramagnétiques à 17 électrons adoptent une géométrie de type plan-carré déformée, les atomes de Br occupant les positions axiale et équatoriale. Les analyses «DSC» et «TGA» des ces composés ont démontré qu’ils sont thermiquement stables jusqu’à ~170 °C; tandis que la spectroscopie d’absorption en solution a démontré qu’ils se décomposent thermiquement à beaucoup plus basse température pour regénérer les complexes divalents ne possédant qu’un seul Br; l’encombrement stérique des substitutants amines accélère cette route de décomposition de façon significative. Les analogues NMe2 et N(morpholinyl) de ces espèces de NiIII sont actifs pour catalyser la réaction d’addition de Kharasch, de CX4 à des oléfines telles que le styrène, tandis qu’il fut découvert que l’analogue le moins thermiquement stable (POCNEt2)Ni est complètement inerte pour catalyser cette réaction. Les complexes (POCNRH)NiBr possédant des fonctions amines secondaires permettent l’accès à des fonctions amines substituées de façon non symétrique via leur réaction avec des halogénures d’alkyle. Un autre avantage important de ces complexes réside dans la possibilité de déprotonation pour préparer des complexes POCN de type amide. De telles tentatives pour déprotoner les fonctions NRH nous ont permis de préparer des espèces dimériques possédant des ligands amides pontants. La nature dimérique des ces complexes [P,C,N,N-(2,6-(i-Pr)2PC6H3CH2NR)Ni]2 (R= PhCH2 et Ph) fut établie par des études de diffraction des rayons-X qui ont démontré différentes géométries pour les cœurs Ni2N2 selon le substituant N : l’analogue (PhCH2)N possède une orientation syn des substitutants benzyles et un arrangement ressemblant à celui du cyclobutane du Ni et des atomes d’azote, tandis que l’analogue PhN adopte un arrangement de type diamant quasi-planaire des atomes du Ni et des atomes d’azote et une orientation anti des substituants phényles. Les espèces dimériques ne se dissocient pas en présence d’alcools, mais elles promouvoient l’alcoolyse catalytique de l’acrylonitrile. De façon intéressante, les rendements de ces réactions sont plus élevés avec les alcools possédant des fonctions O-H plus acides, avec un nombre de «turnover» catalytique pouvant atteindre 2000 dans le cas de m-cresol. Nous croyons que ces réactions d’alcoolyse procèdent par activation hétérolytique de l’alcool par l’espèce dimérique via des liaisons hydrogènes avec une ou deux des fonctions amides du dimère. Les espèces dimériques de Ni (II) s’oxydent facilement électrochimiquement et par reaction avec NBS ou Br2. De façon surprenante, l’oxydation chimique mène à l’isolation de nouveaux produits monomériques dans lesquels le centre métallique et le ligand sont oxydés. Le mécanisme d’oxydation fut aussi investigué par RMN, «UV-vis-NIR», «DFT» et spectroélectrochimie.
