In response to the concern that Minnesota Multiphasic Personality Inventory-2 (MMPI-2; J. N. Butcher, W. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989; J. N. Butcher et al., 2001) Variable Response Inconsistency (VRIN) and True Response Inconsistency (TRIN) score invalidity criteria recommended for use with American samples results…

This paper studies high school classroom sequences, compiled through critical sociolinguistic ethnography, where norm-transgression is made explicit, and how authority is recovered by the teacher after an open period where class participants generally seize to digress. This way, we will be able to approach several dimensions of linguistic…

Biostatistics is traditionally a difficult subject for students to learn. While the mathematical aspects are challenging, it can also be demanding for students to learn the exact language to use to correctly interpret statistical results. In particular, correctly interpreting the parameters from linear regression is both a vital tool and a…

Academic research and newspaper stories suggest that academic misconduct, including plagiarism, is on the increase. This apparent increase coupled with new internet enterprises selling "pass" papers and customized research are worrying trends. Academic misconduct is deeply harmful in a number of ways by devaluing awards, frustrating…

In this article, we operationalize identification of mixed racial and ethnic ancestry among adolescents as a latent variable to (a) account for measurement uncertainty, and (b) compare alternative wording formats for racial and ethnic self-categorization in surveys. Two latent variable models were fit to multiple mixed-ancestry indicator data from…

The purposes of this study were to compare the age of onset of the voice change in African American, White, and Hispanic male students, as well as to describe characteristics of the changing male voice in fourth-, fifth-, and sixth-grade students, using Cooksey's maturation stages. Participants included volunteers from two urban elementary…

Objective: An examination of the academic achievement of children with ADHD by stimulant treatment status must consider this heterogeneity of the disorder. With the dissemination of the final wave of data, the Special Education Elementary Longitudinal Study presents an opportunity to examine the academic achievement of students with ADHD using a…

Early research on the socialization of Latino children has posited that mothers exercise authoritarian practices, compared with lateral reasoning (authoritative) strategies emphasized by Anglo mothers. This work aimed to categorize fixed types of parenting practices tied to the mother's personality rather than to culturally bounded contexts; it…

In this study I examine the relationship between graduating from college with two majors rather than one and labor market earnings using the 2003 National Survey of College Graduates. Because institutions are heterogeneous both in terms of overall quality and in the availability of opportunities to double major, I attempt to control for such…

Autism is one of the most heritable neurodevelopmental conditions and has an early onset, with symptoms being required to be present in the first 3 years of life in order to meet criteria for the "core" disorder in the classification systems. As such, the focus on identifying a prodrome over the past 20 years has been on pre-clinical…

How can we teach science to English language learners (ELLs) when even our native English speakers have trouble reading the textbook? To help science teachers meet this challenge, this article presents six text-comprehension strategies used by English for Speakers of other Languages (ESOL) teachers: metalinguistic awareness development,…

The incidence of basic concepts in early childhood educational standards is explored across all 50 US states. Concept inclusion in state standards is described in terms of the representation of the universe of basic concepts, representation of concept categories, the depth and breadth of individual concept inclusion, and unique examples.…

Objective: To determine if meaningful groups of at-risk pre-adolescent youth could be identified based on their self-report of physical and sexual abuse histories. Methods: Youth participating in a consortium of ongoing longitudinal studies were interviewed using an audio-computer assisted self-interview (A-CASI) when they were approximately 12…

Classification procedures are common and useful in behavioral, educational, social, and managerial research. Supervised classification techniques such as discriminant function analysis assume training data are perfectly classified when estimating parameters or classifying. In contrast, unsupervised classification techniques such as finite mixture…
