Changes in short-term power output in 10- to 12-year-olds

In this study, we used multi-level regression modelling to assess the influence of age, sex, body size, skinfold thicknesses, maturity, thigh muscle volume and isokinetic leg strength on the development of load- and inertia-adjusted peak (1 s) and mean power (30 s) determined using the Wingate anaerobic test. Fifteen males and 19 females were measured twice, first aged 10.0 +/- 0.3 years and then aged 11.8 +/- 0.3 years. Initial models identified body mass and height as significant explanatory variables (P < 0.05) for peak power and mean power, with an additional age effect for the former. No significant differences between the sexes or maturity effects were observed for either peak or mean power (P > 0.05). The introduction of sum of skinfolds improved the fit of the model and rendered the height term non-significant for both peak and mean power (P> 0.05). An age effect became apparent for mean power. When isokinetic leg strength and thigh muscle volume were entered into the model, the latter exerted a significant effect on both peak and mean power (P< 0.05), whereas isokinetic leg strength was not a significant explanatory variable for either (P> 0.05). In conclusion, thigh muscle volume exerts a positive influence on young people's short-term power output, which is additional to the effects of body mass, sum of skinfolds and age.     

Safe Schools/Healthy Students initiative: Pinellas County,Florida

The Safe Schools/Healthy Students (SS/HS) Initiative in Pinellas County, FL, emerged as a part of a broader local effort to implement creative educational and mental health programs to support children and families. This initiative focused on capacity building, prevention, and intervention efforts and comprehensive evaluation to address the barriers to learning and enhance healthy development. This article describes Pinellas County's plan, and highlights the instrumental roles played by school psychologists, which included grant writing, program and resource coordination, clinical services, program evaluation, staff training, parent advocacy, and steering committee membership. Promising outcomes and generalization of these findings to other communities is also discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 489–501, 2003.     

Dreaming our future: Developing democratic professional practice?

This paper addresses issues in relation to recent criticism of teacher education, set in the broader context of political agitation for changes to the purposes, role and outcomes of education within society. The paper raises questions around the purpose of schooling and its role in modern societies and argues for the pedagogical importance of critical dialogue to a democratic conceptualisation of education and promotes the idea of professional education as democratic practice.     

THE STUDENT–TEACHER RELATIONSHIP QUALITY OF ABUSED CHILDREN

Considering the association between children's quality of relationships with teachers and their academic adjustment, information pertaining to how abused children are functioning in their relationships with teachers could be useful in promoting their academic success—yet there has been limited research in this area. The purpose of this study was to use cluster analyses to explore within‐group differences in relational schemas and quality of student–teacher relationships for 70 abused children. Two clusters of abused children emerged, and as hypothesized, there were significant differences in student–teacher relationships for the two clusters. The cluster with more positive relational schemas had less conflict and less dependency reported by their teachers compared to the cluster with negative relational schemas. However, there were no differences between the clusters in terms of closeness with teachers. Implications for practice in schools are discussed.     

Social support,academic adversity and academic buoyancy: a person-centred analysis and implications for academic outcomes

The present study employed person-centred analyses that enabled identification of groups of students separated on the basis of their perceptions of social support (home and community), academic support, academic adversity and academic buoyancy. Among a sample of 249 young people, including many from high-needs communities, cluster analysis revealed three distinct groups of students: the thriver, supported struggler and at-risk struggler. We compared the three groups on their academic motivation. Analyses revealed significant differences between groups in adaptive motivation outcomes, but no differences in impeding or maladaptive motivation outcomes. Combined, the results speak to the importance of support and academic buoyancy for positive student outcomes.     

Assessment of Autism Symptoms From 6 to 18 Months of Age Using the Autism Observation Scale for Infants in a Prospective High-Risk Cohort

The objectives were to characterize behavioral signs of autism spectrum disorder (ASD) in younger siblings of diagnosed children (high-risk; HR) and examine classification features of the Autism Observation Scale for Infants (AOSI). Participants (501 HR and 180 low-risk [LR]) were assessed between 6 and 18 months using the AOSI and at age 3 for ASD diagnoses. Total AOSI scores differentiated HR infants later diagnosed with ASD starting at 12 months. ROC analyses identified 12- and 18-month cutoff scores associated with 0.52 sensitivity and 0.74 specificity and 0.73 sensitivity and 0.65 specificity, respectively. Although classification accuracy does not support use as a standalone screen, the AOSI identifies features associated with ASD starting at 6 months and differentiates HR infants with ASD by 12 months.     

A treatment and education program for parents and children who are at-risk of abuse and neglect

A treatment program for families at-risk of abusive or neglectful parenting was described and evaluated. The program combined intervention strategies and concepts based on research on abuse, early intervention, education and social service. Treatment and education for the parent and child were provided in the three services of the program: Home-Based, Family School, and Neighborhood Peer Support Groups. At-risk families were identified by a high-risk stress index. Program evaluation was based on 46 families and their 74 preschool-age children. Data collected were: incidence of child abuse or neglect, family stresses, observations of parent-child interactions, family goal measurement, and developmental testing of the children. A significant reduction occurred in the number of children abused or neglected as compared to a similar high-risk, nonintervention sample. The family stresses were reduced, parent-child interactions improved, and the intellectual decline of the children was prevented. Families who participated in all three services gained the most from the program.
