There has been considerable interest in nonlinear latent variable models specifying interaction between latent variables. Although it seems to be only slightly more complex than linear regression without the interaction, the model that includes a product of latent variables cannot be estimated by maximum likelihood assuming normality.…

The purpose of this study was to explore the areas of cooperation in which parent and teacher expectations were the same and where they differed. Data were obtained from a sample of 55 randomly selected primary schools. We analyzed school-to home communications, parental influence on school decisions, and parent involvement in different school…

Holding a bank account is crucial to the income-maximizing and asset-building of households. This study uses 2008 survey data of EITC-eligible households assisted at Volunteer Income Tax Assistance (VITA) sites to document their tax filing behavior and use of Alternate Financial Services (AFS). Specifically, the differences in tax filing and AFS…

Numerous procedures have been suggested for determining the number of factors to retain in factor analysis. However, previous studies have focused on comparing methods using normal data sets. This study had two phases. The first phase explored the Kaiser method, Scree test, Bartlett's chi-square test, Minimum Average Partial (1976&2000),…

For diagnosing many mental disorders, the current "Diagnostic and Statistical Manual of Mental Disorders" ("DSM") system weights each diagnostic criterion equally--each criterion counts the same toward meeting the diagnostic threshold. Research on the diagnostic efficiency of criteria, however, reveals that some diagnostic criteria are more useful…

Over 2000 teachers in the state of Washington received reduction-in-force (RIF) notices in the past two years. The authors link data on these RIF notices to a unique dataset that includes student, teacher, school, and district variables to determine the factors that predict the likelihood of a teacher receiving a RIF notice. They find a teacher's…

This paper analyzes the sum score based (SSB) formulation of the Rasch model, where items and sum scores of persons are considered as factors in a logit model. After reviewing the evolution leading to the equality between their maximum likelihood estimates, the SSB model is then discussed from the point of view of pseudo-likelihood and of…

During the past decade Georgia has received strong international support for education reform, and it represents an interesting case by which the effectiveness of particular interventions in the region can be assessed. Most attempts to analyse progress within the system have so far been concentrated on two aspects of formal education: private and…

This paper estimates vocational education and training (VET) course-completion rates, in order to fill a gap in performance measures for the VET sector. The technique the authors use is to track all VET course enrolments within a three-year window, centred on the year of interest. Then, using an absorbing Markov chain model for a VET course…

Recent changes to federal guidelines for the collection of data on race and ethnicity allow respondents to select multiple race categories. Redefining race subgroups in this manner poses problems for research spanning both sets of definitions. NAEP long-term trends have used the single-race subgroup definitions for over thirty years. Little is…

A biology teacher has developed a rare and troubling neurologic disorder. He hears of an experimental treatment that has produced impressive results. The treatment involves surgically ablating selective parts of the brain at close proximity to the brainstem. There is a risk that, during the procedure, vital parts of the brain could be…

The present study tested a number of theoretically and empirically derived measurement models of the Career Decision Self-Efficacy Scale-Short Form (CDSES-SF) using confirmatory factor analysis. Betz's five-factor model of the CDSES-SF, along with a number of alternative models, demonstrated adequate model fit in two independent samples. Based on…

Context: For practicing health care professionals, waiting for a teachable moment to identify a gap in knowledge could prove critical. Other methods are needed to help health care professionals identify their knowledge gaps. Objective: To assess the effect of performance feedback on Athletic Trainers' (AT) perceived knowledge (PK) and likelihood…

Recent missing data studies have argued in favor of an "inclusive analytic strategy" that incorporates auxiliary variables into the estimation routine, and Graham (2003) outlined methods for incorporating auxiliary variables into structural equation analyses. In practice, the auxiliary variables often have missing values, so it is reasonable to…

Differential item functioning (DIF) occurs when items on a test or questionnaire have different measurement properties for one group of people versus another, irrespective of group-mean differences on the construct. Methods for testing DIF require matching members of different groups on an estimate of the construct. Preferably, the estimate is…
