Factor analysis of the abbreviated conners teacher rating scale: Implications for the assessment of hyperactivity

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.     

Factor analysis of the metropolitan readiness test on first-grade children

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.     

Preliminary norms and technical data for use of the Revised-Children's Manifest Anxiety Scale with kindergarten children

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.     

Who pays? Who benefits? Who decides?

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.      

A Geohistorical Study of ‘The Rise of Modern Science’: Mapping Scientific Practice Through Urban Networks, 1500–1900

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.

Two games in town: a comparison of dealer and auction prices in contemporary visual arts markets

The article tests a couple of hypotheses relating to markets where demand is not taken as a given, but subject to sophisticated and encompassing price-building strategies. The study uses a data set that provides quoted dealer prices for medium-sized works of 100 leading visual artists from 1970 to 2004. These data are compared with auction price results for works by the same artists. The study reports significant discrepancies with respect to the relationship between the age of artists and prices paid for their works in the two markets, and with respect to general price developments in the two markets as measured by indices.
