In second language acquisition, it is well known that an early age of onset and an extensive amount of naturalistic input are key elements promoting successful learning outcomes. What is less well known is what outcomes we can expect when the main source of these elements is full-immersion schooling, defined for the purposes of this study as a…

This study explores how extracurricular activities experiences affect students' leadership development outcomes. The current status of students' experiences of extracurricular activities and leadership development outcomes identified. Also, it analyzed the correlation, as well as how they contribute to the college students' leadership. Lastly, the…

Depression is a risk factor for suicide in adolescents making it essential for school nurses to identify and refer at-risk adolescents for resources. At the project site, there is no current practice to routinely assess for adolescent depression. The purpose of this quantitative, quasi-experimental quality improvement project was to determine if…

Meta-analyses are often used to synthesize the findings of studies examining the correlational relationship between two continuous variables. When only dichotomous measurements are available for one of the two variables, the biserial correlation coefficient can be used to estimate the product-moment correlation between the two underlying…

Empathy, the ability to feel the emotions of others and respond affectively to these emotions, is an important factor in the development of social competence. The purpose of this study was to examine empathy levels in toddlers with moderate hearing loss (MHL) compared to toddlers with no hearing loss (nHL), and to explore the relation between…

Clinically, social interaction, including gaze-triggered attention, has been reported to be impaired in autism spectrum disorder (ASD), but psychological studies have generally shown intact gaze-triggered attention in ASD. These studies typically examined gaze-triggered attention under simple environmental conditions. In real life, however, the…

In equating, when common items are internal and scoring is conducted in terms of the number of correct items, some pairs of total scores ("X") and common-item scores ("V") can never be observed in a bivariate distribution of "X" and "V"; these pairs are called "structural zeros." This simulation…

Rodents require a minimal time period to explore a context prior to footshock to display plateau-level context fear at test. To investigate whether this rapid fear plateau reflects complete memory formation within that short time-frame, we used the immediate-early gene product Arc as an indicator of hippocampal context memory formation-related…

Although tongue twisters have been widely use to study speech production in healthy speakers, few studies have employed this methodology for individuals with speech impairment. The present study compared tongue twister errors produced by adults with dysarthria and age-matched healthy controls. Eight speakers (four female, four male; mean age =…

The aim of our study was to evaluate the frequencies of myeloid dendritic cells (mDCs) and plasmacytoid dendritic cells (pDCs) in children with ASD. Subjects were 32 children with ASD and 30 healthy children as controls. The numbers of mDCs and pDCs and the expression of CD86 and CD80 on the entire DCs were detected by flow cytometry. ASD children…

Purpose: The aim of this study was to add further knowledge about the usefulness of the Voice Range Profile (VRP) assessment in clinical settings and research by analyzing VRP dual-microphone equipment precision, reliability, and room effect. Method: Test-retest studies were conducted in an anechoic chamber and an office: (a) comparing sound…

This brief summarizes "Comparability in Balanced Assessment Systems for State Accountability," published in "Educational Measurement: Issues and Practice" (Evans & Lyons 2017). The study evaluated comparability claims in local scoring of performance assessments across districts participating in New Hampshire's Performance…

In the last two decades, a decisive anti-foundationalist turn has emerged in educational philosophy and theory. With such a shift, both the possibility and the desirability to conceive of educational processes and practices in terms of mastery and predictability has been challenged. In this paper, by locating my work on such an…

There are many well-known or new methods to adjust statistical tests for multiplicity. This article provides an illustration helping lecturers or consultants to remember the differences of three important multiplicity adjustment methods and to explain them to non-statisticians.

The combined usage of qualitative comparative analysis (QCA) and process tracing (PT) in set-theoretic multi-method research (MMR) holds great potential for reaching valid inferences. Established views of case selection after QCA hold that studying negative cases provides lessons about the causes of an outcome in a limited set of circumstances. In…
