Context: National financial data show that rural referral center (RRC) hospitals have performed well financially. RRC hospitals' median cash flow margin ratio was 10.04% in 2002 and grew to 11.04% in 2004. Purpose: The aim of this study is to compare the ratio analysis of key operational and financial performance measures of for-profit RRCs to…

Factor analysis is arguably one of the most important tools in the science of mental abilities. While many studies have been conducted to make recommendations regarding "best practices" concerning its use, it is unknown the degree to which contemporary ability researchers abide by those standards. The current study sought to evaluate the typical…

This article suggests a method for estimating a test-score equating relationship from small samples of test takers. The method does not require the estimated equating transformation to be linear. Instead, it constrains the estimated equating curve to pass through two pre-specified end points and a middle point determined from the data. In a…

The objective of this study was to investigate the effect of surgical rapid maxillary expansion (SRME) on vowel production. The subjects included 12 patients, whose speech were considered perceptually normal, that had undergone surgical RME for expansion of a narrow maxilla. They uttered the following Turkish vowels, ([a], [[epsilon]], [[inverted…

This "What Works Clearinghouse Procedures and Standards Handbook (Version 3.0)" provides a detailed description of the standards and procedures of the What Works Clearinghouse (WWC). The remaining chapters of this Handbook are organized to take the reader through the basic steps that the WWC uses to develop a review protocol, identify…

The Type I error rates and the power of IRT likelihood ratio test and cumulative logit ordinal logistic regression procedures in detecting differential item functioning (DIF) for polytomously scored items were investigated in this Monte Carlo simulation study. For this purpose, 54 simulation conditions (combinations of 3 sample sizes, 2 sample…

In as much as educational research is concerned with individual student assessment and development, it is surprising that single-subject designs are not more readily utilized in classroom-based action research. The purpose of this article is to emphasize benefits of single-subject research in the K-12 setting, given that teachers teach and assess…

This study utilized a replicated one-group pretest-posttest design with 3 month follow-up to evaluate the impact of a one-day continuing education training on the evidence-based practice (EBP) process with community practitioners (N = 69). Outcome measures assessed the level of workshop participants' familiarity with the EBP process, their…

The importance of phonological awareness for learning to read may depend on the linguistic properties of a language. This study provides a careful examination of this language-specific theory by exploring the role of phoneme-level awareness in Mandarin Chinese, a language with an orthography that, at its surface, appears to require little…

This report examines the consequences of differential item functioning (DIF) using simulated data. Its impact on total score, item response theory (IRT) ability estimate, and test reliability was evaluated in various testing scenarios created by manipulating the following four factors: test length, percentage of DIF items per form, sample sizes of…

Based on previous research, it is apparent that many National Collegiate Athletic Association (NCAA) Division I institutions benefit from the existence of and success in intercollegiate athletics. However, there are few, if any, studies that have researched the impact of intercollegiate athletics at National Association of Intercollegiate…

Purpose: The purpose of this paper is to explore the significance of cross-cultural training and career attitudes for expatriation career move in the context of China, whether cross-cultural training is perceived necessary, and the consequence of providing such cross-cultural training. Design/methodology/approach: Data were collected from 82…

Pretest-posttest experimental designs often are used in randomized control trials (RCTs) in the education field to improve the precision of the estimated treatment effects. For logistic reasons, however, pretest data often are collected after random assignment, so that including them in the analysis could bias the posttest impact estimates. Thus,…

This study is an evaluation of the behavior of the Liu-Agresti estimator of the cumulative common odds ratio when identifying differential item functioning (DIF) with polytomously scored test items using small samples. The Liu-Agresti estimator has been proposed by Penfield and Algina as a promising approach for the study of polytomous DIF but no…

This study examined the relationship between characteristics of the Broader Autism Phenotype (BAP) and nonverbal sensitivity, the ability to interpret nonverbal aspects of communication, in a non-clinical sample of college students. One hundred and two participants completed a self-report measure of the BAP, the Autism Spectrum Quotient (AQ), and…
