An investigation of the K-ABC,WISC-R,and W-JPB,part two,with learning disabled children

The purpose of this study was to examine the relationship of the Kaufman Assessment Battery for Children (K-ABC), the WISC-R, and the Woodcock-Johnson Psychoeducational Battery (W-JPB), Part Two, with children who experience learning disabilities. Correlational analyses were used to examine relationships among the WISC-R, K-ABC Mental Processing and Achievement scales, and the W-JPB Achievement scales. Thirty-four children with learning disabilities (mean age 8–11 years) received all three measures. Correlation coefficients indicated stronger and more consistent relationships between the WISC-R and W-JPB Achievement tests than between the K-ABC and W-JPB Achievement tests. Significant relationships between the WISC-R Full Scale IQ and the K-ABC Mental Processing Composite (MPC) revealed evidence of validity for this learning disabled sample. However, correlation coefficients among the K-ABC Achievement subtests and the W-JPB Achievement clusters indicated both convergent and discriminant validity. Thus, it is suggested that both the K-ABC MPC, for assessment of cognitive abilities, and the W-JPB Achievement clusters could be employed in discrepancy formulas for special education placement of children with learning disabilities.     

Understanding the experiences of bilingual,Latino/a adolescents: Voices from gifted and general education

Eight gifted and eight general‐education students engaged in discussions regarding their observations of, experiences in, and recommendations for education. Six categories emerged through qualitative analysis of their conversations. These categories include: problem solving, task commitment, self‐perceptions, education, communication, and discrimination. Content within each category provides a glimpse into the students’ perceptions of their schooling experiences. The roles of ethnic identity development, identification with majority culture, adolescence, and gifted‐ness are examined and recommendations for future research are provided.     

一种基于Kalman滤波和能量原理的实时损伤识别方法(英文)

目的:建立一种损伤识别方法,能够实时地监测多自由度复杂结构中构件的损伤情况。方法:1.用能量原理对结构刚度进行解构,建立结构单元刚度和节点响应之间的关系;2.用Kalman滤波原理分析结构刚度的预测值和测量值,迅速对结构的刚度进行识别(图6–9);3.对每一步计算进行耗时监测,确保算法的实时性(图10)。结论:1.该方法能够较准确地得到结构的刚度信息,同时得出损伤单元的损伤位置和损伤量;并且收敛速度快,计算量小,具有很强的实时性和抗噪能力;2.对于本文的桁架结构,所有杆件刚度均能在0.4 s内收敛,平均每一荷载步计算时间约为0.0012 s,小于采样周期1/256 s,说明该方法可以迅速、准确地对结构进行实时的监测。
