Forty-nine learning disabled (LD), 30 emotionally disturbed(ED), and 44 unclassified (UC) boys originally sampled by Brooks (Note 1) and Jackson (Note 4) when they were 6 to 11 years of age, were relocated in 1979, and their current classification determined. Lambda, an index of predictive association, showed that a 53% improvement in the accuracy of prediction of 1979 classification was obtained when 1975 classification was given. The ED classification was the least stable, with 60% of the children originally classified ED changing their classification over four years, though only 19% of the originally LD and ED children were unclassified four years later. 相似文献

A set of behavioral objectives was developed for the consultant role of the school psychologist, based on Meyers' consultation model. A Likert-type questionnaire was developed to assess the degree to which teachers and school psychologists agreed upon the desirability and the actual accomplishment of these objectives. Based on a sample of 120 teachers and 83 school psychologists, it was found that both groups perceived a difference between the “desired” role and the role that school psychologists actually fulfill. However, there were also significant differences between teachers' and school psychologists' rating of the “actual” role, the school psychologists' rating agreeing more with the consultation model. Examination of individual items showed greater acceptance of objectives relating to Meyers' level of indirect service to the child, and less acceptance of Meyers' levels of direct service to the teacher and service to the school system. 相似文献

This study assessed kinematic differences between different foot strike patterns and their relationship with peak vertical instantaneous loading rate (VILR) of the ground reaction force (GRF). Fifty-two runners ran at 3.2 m · s?1 while we recorded GRF and lower limb kinematics and determined foot strike pattern: Typical or Atypical rearfoot strike (RFS), midfoot strike (MFS) of forefoot strike (FFS). Typical RFS had longer contact times and a lower leg stiffness than Atypical RFS and MFS. Typical RFS showed a dorsiflexed ankle (7.2 ± 3.5°) and positive foot angle (20.4 ± 4.8°) at initial contact while MFS showed a plantar flexed ankle (?10.4 ± 6.3°) and more horizontal foot (1.6 ± 3.1°). Atypical RFS showed a plantar flexed ankle (?3.1 ± 4.4°) and a small foot angle (7.0 ± 5.1°) at initial contact and had the highest VILR. For the RFS (Typical and Atypical RFS), foot angle at initial contact showed the highest correlation with VILR (r = ?0.68). The observed higher VILR in Atypical RFS could be related to both ankle and foot kinematics and global running style that indicate a limited use of known kinematic impact absorbing “strategies” such as initial ankle dorsiflexion in MFS or initial ankle plantar flexion in Typical RFS. 相似文献
