Log-linear models for contingency tables are a key tool for the study of categorical inequalities in sociology. However, the conventional approach to model selection and specification suffers from at least two limitations: reliance on oftentimes equivocal diagnostics yielded by fit statistics, and the inability to identify patterns of association…

This publication presents estimates of apprentice and trainee activity in Australia for the December quarter 2011. The figures in this publication are derived from the National Apprentice and Trainee Collection no.71 (March 2012 estimates). The most recent figures in this publication are estimated (those for training activity from the June quarter…

This publication presents estimates of apprentice and trainee activity in Australia for the September quarter 2010. The figures in this publication are derived from the National Apprentice and Trainee Collection no.66 (December 2010 estimates). The most recent figures in this publication are estimated (those for training activity from the March…

This publication presents estimates of apprentice and trainee activity in Australia for the June quarter 2012. The figures in this publication are derived from the National Apprentice and Trainee Collection no.73 (September 2012 estimates). The most recent figures in this publication are estimated (those for training activity from the December…

This publication presents estimates of apprentice and trainee activity in Australia for the September quarter 2012. The figures in this publication are derived from the National Apprentice and Trainee Collection no.74 (December 2012 estimates). The most recent figures in this publication are estimated (those for training activity from the March…

This study evaluates the effects of an intervention aimed at improving representational flexibility in linear-function problems. Forty-nine students aged 13-16 participated in the study. A pretest-intervention-posttest design with an experimental and control group was used. At pretest, both groups solved a choice test, where they could freely…

The concepts of demand, need, desire, and take-up were discussed in the context of preschool services in three small areas of Inner London. It was shown by using log-linear models that desire for preschool provision could be efficiently predicted by a combination of sociodemographic variables. (Author/IRT)

Data from the 1970 Brazilian Census are used to explore the effects of parents' investments in their children's education on the pattern of future income distribution and on the intergenerational transmission of inequality, using a simulation model. Appended are 21 references. (Author)

Explains some observed library circulation frequency distributions through use of a simple stochastic model for the borrowing of books from a library collection. Parameters of the model are described and the model is applied to circulation data from three academic libraries. (Author/SW)

This study estimates the proportion of academic and public library acquisitions in the United Kingdom for which a UK MARC record is available at the time of cataloging. A beta-binomial model is used to attribute standard errors to each estimate and to compare differences between the two types of libraries. (Author/LRW)

Two models of library circulation, the Markov model and the mixed Poisson Model, are applied to circulation statistics from the University of Saskatchewan. Goodness-of-fit tests indicate that neither model fits the data; in both cases, the set of noncirculating items is larger than that predicted by the model. (Author/LRW)

Using an input-output framework, the author derives hypotheses on wage differentials based on the assumption that human capital (in this case, education) will explain workers' wage differentials. The hypothetical wage differentials are tested on data from the Italian economy. (RW)

Statistical data can be represented in a number of qualitatively different ways, the choice depending on the following three conditions: the concepts to be investigated; the nature of the data; and the purpose for which they were collected. This paper begins by setting out frameworks that describe the nature of statistical thinking in schools, and…

Reports on Commonwealth Scientific and Industrial Research Organization (Australia) efforts to establish library staffing standards by use of statistics on current library operations and comparison of figures for number of libraries. Research methodology, use of mathematical models, factor analysis and regression analysis, and measures of…

Investigates the dimensions underlying performance on the diagrams, tables, and maps subset of the Swedish Scholastic Aptitude Test. Analyzes data from two test versions by using a structural-equation modeling technique on 14,463 and 19,636 examinees respectively. Concludes that gender difference in performance is due, to a great extent, to the…
