Discriminant analysis was used to examine factors that influenced the educational diagnoses of a sample of 80 referred students in grades 1 to 6. All students had WISCR Full Scale IQs between 63 and 75, which includes the range of scores that is ±2 SEm around the cutoff value of 69 used by the student's school district to define the upper limit of the mildly retarded classification. The results indicate that the recommendations made by the multidisciplinary teams were associated primarily with the level of the Full Scale IQ. 相似文献

A factor analysis of the abbreviated Conners Teacher Rating Scale (CTRS) was completed using a sample of 108 regular and special education students. Two factors accounted for 69.5% of the total response variance: Factor I consisted of items describing attention deficits and motor activity, and Factor II consisted of items describing excessive affective reactions. It is suggested that the abbreviated CTRS be interpreted with respect to its latent structure, rather than to one global score as has been common practice. 相似文献

The factor composition of the Metropolitan Readiness Test was investigated, using 1st-grade subjects in a suburban school district. In this analysis, a total battery score was supported, as well as a second factor believed to represent a language dimension of the test. None of the MRT's other content areas (auditory, visual, or quantitative abilities) or a distinct prereading measure were identified for this sample. 相似文献

The Revised-Children's Manifest Anxiety Scale (Reynolds & Richmond, 1978) was administered to 97 kindergarten children. Coefficient alpha reliabilities of .79 for males (N = 53), .85 for females (N = 44), and .82 for the total sample resulted. Contrary to findings with older children, no sex differences occurred in scoring on the anxiety scale. The kindergarten children generally scored higher on the anxiety scale than did older children. Lie scale scores were comparable to those of other primary grade children. Implications for use of the scale with young children are discussed. 相似文献

This paper was presented at the symposium dedicated to the 25th anniversary of the publication of Patrons Despite Themselves: Taxpayers and Arts Policy (Feld et al. 1983), held by the Association for Cultural Economics International, Boston, June 2008. It considers alternative
means of providing indirect tax-based state support of the arts, such as the use of tax credits as opposed to tax deductions
for charitable contributions, matching grants, and support applied to specific projects. It also considers the problem of
broad-based changes to tax policy that have unintended consequences for arts organizations.

Using data on the ‘career’ paths of one thousand ‘leading scientists’ from 1450 to 1900, what is conventionally called the
‘rise of modern science’ is mapped as a changing geography of scientific practice in urban networks. Four distinctive networks
of scientific practice are identified. A primate network centred on Padua and central and northern Italy in the sixteenth
century expands across the Alps to become a polycentric network in the seventeenth century, which in turn dissipates into
a weak polycentric network in the eighteenth century. The nineteenth century marks a huge change of scale as a primate network
centred on Berlin and dominated by German-speaking universities. These geographies are interpreted as core-producing processes
in Wallerstein’s modern world-system; the rise of modern scientific practice is central to the development of structures of
knowledge that relate to, but do not mirror, material changes in the system.
