Much previously published material for estimating the reliability of classification has been based on the assumption that a test consists of a known number of equally weighted items. The test score is the number of those items answered correctly. These methods cannot be used with classifications based on weighted composite scores, especially if…

More research is needed to distinguish between actual and artificial sex differences, and greater attention should be paid to individual differences, since at this point sex appears to account for very little variability in human performance. (JC)

Results from the National Assessment of Educational Progress (NAEP) and other large scale tests are often reported as rank ordered lists showing mean values for each of the 50 states. Using data from the 2003 State NAEP Assessment, this paper examines the standard errors associated with State NAEP scores and explains why the use of rank order…

Three alternative models are presented to represent the decreased importance of the status of first job on current occupational status overtime; there is evidence that the effects of first job erode with time. Models not explicitly incorporating labor force experience may suffer a serious specification error. (Author/AJ)

Modern software practices call for the active involvement of business people in the software process. Therefore, programming has become an indispensable part of the information systems component of the core curriculum at business schools. In this paper, we present a model-based approach to teaching introduction to programming to general business…

Leow (2001a) employed concurrent data elicitation procedures (think aloud protocols) to investigate the benefits of textual enhancement, premised on the roles of attention and awareness (noticing), in second/foreign language (L2) learning. The present study follows this methodological approach to further investigate these benefits in addition to…

Based on an analysis of 46 small geographic areas, birth weight statistics were related to variables of income, home maintenance, medical and dental care, and aid to dependent children. It was suggested that birth weight statistics may be more effective than infant mortality statistics for many purposes where death data are now used. (EH)

A group of students on a post-graduate teacher training course took part in a Reluctant Learner Project. On one afternoon a week for a term, each student took a small group of comprehensive school pupils from a low stream class out of school and engaged in mutually agreed activities. (Editor)

As part of a larger investigation of the effects of introducing a formal unit structure into elementary schools, an attempt was made to predict in which of the newly unitized schools teachers would first show an increase in task interdependence. Prominent among the various features under consideration in the prediction study are teacher norms…

This volume contains 10 original papers discussing methodologies applicable to performing psychosocial research on substance abuse, particularly abuse with drugs. Eight data analysis strategies are discussed by the authors: automatic interaction detection, actuarial prediction, cluster and typological analysis, path analysis, factor analysis,…

Despite considerable progress in narrowing the health gap between whites and nonwhites (including blacks, American Indians, Asian Americans) in the last 20 years, substantial differences persist. According to most indicators, nonwhites are less healthy than whites. Yet nonwhites see physicians somewhat less often and are less likely to have…

The derivation and analysis presented in this report allow the experimenter to perform multifactor contrasts on correlation coefficients for several populations in an experimental design. Cells of the design constitute independent groups of subjects on which two measures have been taken and correlated. Measures need not be identical for each…

This paper examines the effect of enforcement of Equal Employment Opportunity (EEO) laws, between 1967 and 1974, on the earnings of females and males, and on the male/female earnings differential. Although discrimination in employment against women has been illegal for more than a decade, between 1967 and 1974 the male/female earnings differential…

This study investigated the relationships between the organizational behavior perceptions of superintendents and elementary principals and the amount of role conflict and ambiguity expressed by elementary principals. A sample of 74 nonurban school districts yielded a total of 343 administrator respondents. The study analyzed relationships between…
