Over the twentieth century, a growing group of students has been transferred into considerably expanded special education systems. These programs serve children with diagnosed impairments and disabilities and students with a variety of learning difficulties. Children and youth “with special educational needs” constitute a heterogeneous group with social, ethnic, linguistic, and physical disadvantages. An increasingly large percentage of those students at risk of leaving school without credentials participate in special education, a highly legitimated low status (and stigmatizing) school form. While most countries commit themselves to school integration or inclusive education to replace segregated schools and separate classes, cross-national and regional comparisons of special education’s diverse student bodies show considerable disparities in their (1) rates of classification, (2) provided learning opportunities, and (3) educational attainments. Analyzing special education demographics and organizational structures indicates which children and youth are most likely to grow up less educated and how educational systems distribute educational success and failure. Findings from a German-American comparison show that which students bear the greatest risk of becoming less educated depends largely on definitions of “special educational needs” and the institutionalization of special education systems.

Population growth, urban development, and increased commercial and industrial activity in the south-central Puget Lowlands of Washington State has led to an increased demand for groundwater. The Vashon till is a glacially consolidated, low-permeability unit comprising unstratified clay, silt, cobbles and boulders with ubiquitous coarse-grained lenses and is an extensive surficial unit throughout the south-central Puget Lowland. Thus, understanding the physical and hydrological characteristics – specifically, the hydraulic conductivity – of this unit is a necessary component of a groundwater model. This study provides (1) a record of the physical characteristics of Vashon till deposits within the study area; and (2) an estimate of the highest, lowest, and average value of saturated hydraulic conductivity based on the grain-size distribution of Vashon till samples collected from six field sites in the Puyallup River Watershed. Analysis shows that the average moisture content ranges between about 1 and 6%, average dry bulk density is about 2.20 g/cm3, and average porosity is about 17%. Grain-size distributions show that half of the samples analyzed are well graded, while the other half is poorly graded. Grain-size distributions also show an average d10 value of about 0.20 mm, and average ff values ≤ 16%, which are key values in estimating the saturated hydraulic conductivity of over-consolidated glacial deposits. Based on these observed values, the estimates of hydraulic conductivity range from a minimum of 0.02 m/d to a maximum of 1.38 m/d in within the general Vashon till.

The quantitative literature on physical activity participation patterns leaves many questions about the place and significance of physical activity in the lives of young people unanswered. This paper begins to address this absence by attempting to understand physical activity from the point of view of young people and in relation to other aspects of their lives. It discusses interviews with 28 female and 34 male students from three Australian high schools chosen because they provided the opportunity to include students from different geographical, social and cultural locations. Students were asked to reflect upon their past and current engagement in physical activity, and the impact of factors such as their location, family, and school in their access and interest. Different spaces and places proved important in the nature of the physical activity available, its significance to young people and the kinds of identities which could be constructed.

Loading of the femoral neck (FN) is dominated by bending and compressive stresses. We hypothesize that adaptation of the FN to physical activity would be manifested in the cross-sectional area (CSA) and section modulus (Z) of bone, indices of axial and bending strength, respectively. We investigated the influence of physical activity on bone strength during adolescence using 7 years of longitudinal data from 109 boys and 121 girls from the Saskatchewan Paediatric Bone and Mineral Accrual Study (PBMAS). Physical activity data (PAC-Q physical activity inventory) and anthropometric measurements were taken every 6 months and DXA bone scans were measured annually (Hologic QDR2000, array mode). We applied hip structural analysis to derive strength and geometric indices of the femoral neck using DXA scans. To control for maturation, we determined a biological maturity age defined as years from age at peak height velocity (APHV). To account for the repeated measures within individual nature of longitudinal data, multilevel random effects regression analyses were used to analyze the data. When biological maturity age and body size (height and weight) were controlled, in both boys and girls, physical activity was a significant positive independent predictor of CSA and Z of the narrow region of the femoral neck (P < 0.05). There was no independent effect of physical activity on the subperiosteal width of the femoral neck. When leg length and leg lean mass were introduced into the random effects models to control for size and muscle mass of the leg (instead of height and weight), all significant effects of physical activity disappeared. Even among adolescents engaged in normal levels of physical activity, the statistically significant relationship between physical activity and indices of bone strength demonstrate that modifiable lifestyle factors like exercise play an important role in optimizing bone strength during the growing years. Physical activity differences were explained by the interdependence between activity and lean mass considerations. Physical activity is important for optimal development of bone strength.
