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.

The WISC-R scores for groups of children identified by school personnel as needing special education services were factor analyzed according to type of classification. WISC-R factor loadings were obtained for the scores of children labeled Learning Disabled, Educable Mentally Impaired, and Emotionally Impaired, as well as groups labeled Other and None. Overall, results show the WISC-R to be factorially similar for all groups, with two principal factors emerging which correspond to the Verbal-Performance structure of the test. Significance tests among mean scale scores and IQ scores yielded few meaningful differences across groups. 相似文献

Inspection of the 1972 revised norms for the Stanford-Binet demonstrate that the average mental age for a particular CA no longer numerically corresponds to that CA. Thus, mental ages derived from the test cannot any longer be interpreted as mental ages. A table of test ages based on the 1972 norms is provided. 相似文献
