Previous studies have found evidence for gender and racial/ethnic differences in depressive symptoms in adolescence; however, the mechanisms driving this relationship are poorly understood. The goal of this study was to examine the role of individual differences in dispositional coping in the relationships between gender and depressive…

Online purchasing has increased dramatically over the past 10 years and the pace is expected to continue to accelerate. This new channel of purchasing poses a challenge to online retailers as they strive to increase online repurchasing behavior. This non-experimental study addresses the problem of how to support a rapidly growing online…

Our purpose is to proffer QuantCrit methodological approaches to interrogate notions of statistical practice by convention. We present two approaches to meta-analysis and mean effect size calculations for student achievement. The first approach is the conventional approach which applies between-group differences to calculate effect sizes…

In this study, I used American Community Survey (ACS) 2005-2015 data to examine the enrollment effect of the Post-9/11 GI Bill; the analysis resulted in three main findings: First, although the New GI Bill has increased overall college enrollment by about 3 percentage points on average, the effect was much larger immediately after the bill's…

Summer break sets students in grades K-12 back by at least one month of instruction and has the strongest impact on mathematics retention. This study investigates whether there is evidence of the summer gap effect at the university level for engineering students enrolled in the introductory calculus course sequence, and possible demographic…

Findings from previous cross-sectional studies showed that while toddlers around their first birthday imitate selectively, that is, they systematically omit some kinds of target action steps or they copy only the goal, but not the means of the modeled actions, older toddlers imitate more exactly. The aim of the present article is to provide…

Autism spectrum disorder (ASD) characteristics seem to abate over time, but whether this protracts until late adulthood is largely unknown. We cross-sectionally investigated self- and other-reported ASD characteristics of adults with (ASD: N[subscript max-self] = 237, N[subscript max-other] = 130) and without ASD (COM: N[subscript max-self] = 198,…

The topic of student cheating at higher education has been studied empirically for more than 80 years in the U.S., and has become a subject of concern in the rest of the world, where academic research has spread to other continents. However, institutional research has just begun in South American countries, where studies and surveys conducted in…

Reliable measurements are key to social science research. Multiple measures of reliability of the total score have been developed, including coefficient alpha, coefficient omega, the greatest lower bound reliability, and others. Among these, the coefficient alpha has been most widely used, and it is reported in nearly every study involving the…

The observed increase in economic inequality, where the major concern is relative to the huge growth of the highest incomes, motivates to revisit classical measures of inequality and to offer new ways to synthesize the variability of the entire income distribution. The idea is to provide policy makers a way to contrast the economic position of the…

The present study aims to examine gender differential item functioning (DIF) in the reading comprehension section of a high stakes test using cognitive diagnosis models. Based on the multiple-group generalized deterministic, noisy "and" gate (MG G-DINA) model, the Wald test and likelihood ratio test are used to detect DIF. The flagged…

Including all children in large-scale educational studies is a pressing concern. Omitting certain types of children from studies can lead to skewed findings that promote inaccuracies about learning levels or educational quality. Increasingly, assessments are a method for investigating the quality of education systems, but national assessments are…

The present study investigated developmental differences and stability in possible selves within the educational and occupational domain among a diverse sample of urban youth (N = 319). A secondary aim was to test the "aspiration-expectation gap" while exploring the role of subjective social class and gender differences. Results did not…

The purpose of this study was to provide a cross-cultural comparison between China and the United States of neutralization and academic entitlement on academic dishonesty, often referred to as college cheating. The sample consisted of 434 American Students and 180 Chinese students. Neutralization was a predictor of cheating in college for both the…

Background: Women and students of color are widely underrepresented in most STEM fields. In order to investigate this underrepresentation, we interviewed 201 college seniors, primarily women and people of color, who either majored in STEM or started but dropped a STEM major. Here we discuss one section of the longer interview that focused on…
