This study evaluates how domains of physical activity (PA) in youth predict later PA and assesses factors influencing changes in sports participation. Young people from the Children’s Sport Participation and Physical Activity study (n = 873; baseline age 10–18 years; 30.4% male) completed self-report surveys in 2009 and 2014. In a multiple linear regression analysis, participation frequency in club sport (β = 0.18) and extracurricular sport (β = 0.13) significantly predicted PA 5 years later, adjusted for age, sex and urban/rural classification (P < 0.01). Overall, rates of regular (at least once per week) youth sports participation were high (males 79.3–85.5%; females 74.8–83.2%). Uptake and dropout of specific sports varied widely. Despite high levels of migration into and out of Gaelic games, they remained popular at follow-up. Weight training was the only sport that increased in both sexes (P < 0.05). Fitness, friends and enjoyment were top motivations for taking up a new sport. Other commitments, a lack of interest and time were important factors leading to sports dropout. PA promotion strategies should include youth sport, take into consideration what sports are attractive to young people and address reasons for uptake and dropout. 相似文献

Research indicates that the performance-gap between English Language Learners (ELLs) and their non-ELL peers is partly due to ELLs' difficulty in understanding assessment language. Accommodations have been shown to narrow this performance-gap, but many accommodations studies have not used a randomized design and are based on relatively small sample sizes. Addressing such issues, we administered a standard-based mathematics assessment to approximately 3,000 Grade 9 ELL and non-ELL students under five different language-based accommodations. Results indicate that many of these accommodations did not produce significant gains for the recipients. Some even had a negative impact. We believe several factors may explain these findings. First, newer assessments, including those developed for this study, may have been linguistically modified to the point that further modification has only a limited effect. Second, the language of instruction may have not adequately prepared students for the assessment. If the language of instruction (textbook, etc.) contains unnecessary linguistic complexity, then students may not have had the opportunity to learn the assessed content. A third factor is students’ unfamiliarity with these accommodations because they are seldom used in classroom instruction and teacher assessments. We discuss our findings and implications for policymakers, assessment developers, practitioners, and researchers. 相似文献

Knowledge management (KM) is crucial for organizations to enhance competitive advantage. While the issues of KM have been widely discussed by numerous researchers, there is a paucity of studies pertaining to KM adoption and practice for the life insurance industry. Therefore, this paper aims to investigate the main factors affecting the life insurance business in adopting and applying KM. An exploratory field study utilizing an inductive methodology involving a multiple-case study approach was undertaken by conducting interviews with 10 key knowledge workers from life insurance enterprises in various stages of KM development and use. We utilized content analysis techniques to identify the factors with their associated variables and further developed a research model. This study offers a comprehensive model for future KM research and provides managerial implications for organizations, particularly life insurance enterprises, to better realize the worth of KM and the possible impediments involved in the processes of adopting and implementing KM. 相似文献

The transition from maternity services to community child health services on discharge from hospital occurs at a potentially vulnerable time for women in their transition through the childbearing/early parenting continuum. Their experiences contribute to their developing maternal efficacy and parenting skill. The ideal attributes of services that aim to support women and their families during this time include continuity of care, service integration, and birth in accessible, community-based contexts. The purpose of this study was to investigate aspects of maternal experience of mothers attending with their infants a publicly funded drop-in postnatal health-care service, as well as their reasons for attending and their perceptions of its usefulness to them as a mechanism of continuity and a source of support. 相似文献

Long-standing and enduring problems in quantitative studies of educational effectiveness relate to fitting models that adequately reflect the complex inter-relationships among multivariate, multilevel factors affecting students’ educational progress, particularly among those that operate within classrooms. This article illustrates one approach to solving such difficulties by combining the analytic approaches of multilevel analysis and structural equation modeling in a two-stage process. The data used are drawn from a longitudinal study of teacher and school effectiveness for three Grade-level cohorts of 4,558 students clustered within 334 class/teacher groups in 52 elementary schools. The article provides estimates of inter-relationships among achievement and social background factors including ‘critical events’ on students’ progress in mathematics, together with their affective schooling experiences and inattentive behaviors in the classroom. Findings are presented indicating the extent to which progress can be accounted for by the grouping effects of students within classes and schools, highlighting the importance of accounting for the interdependent effects among variables. Both the substantive and methodological implications of the findings are discussed. Résumé De longue date et de manière persistante, les problèmes posés dans les études quantitatives sur l’efficacité de l’enseignement tiennent à la capacité d’élaborer des modèles qui reflètent de manière adéquate la complexité des interrelations parmi les multiples variables, avec leurs multiples niveaux, qui interviennent dans la progression des étudiants, particulièrement en ce qui concerne celles qui opèrent à l’intérieur même des classes dans les écoles. Cet article présente une approche cherchant à résoudre de telles difficultés en combinant les techniques de l’analyse multivariée avec un modèle d'équation structurale impliquant un processus à deux niveaux. Les données utilisées sont tirées d’une étude longitudinale sur l’efficience des écoles et des enseignants portant sur des cohortes de trois degrés scolaires touchant 4558 élèves provenant de 334 groupes classe/enseignant dans 52 écoles élémentaires. L’article fournit des estimations concernant les interrelations entre la réussite scolaire et des facteurs relevant de l’environnement social incluant des “événements critiques” dans la progression des élèves en mathématiques, mis en rapport avec leur expérience scolaire affective et des comportements inattentifs en classe. Les conclusions présentées indiquent la mesure dans laquelle le progrès peut être expliqué par des effets de groupes d’élèves à l’intérieur des classes et des écoles. Elles éclairent l’importance de la prise en compte de l’interdépendance des éléments parmi les variables. La justification et les implications méthodologiques des conclusions sont discutées.
