The National Occupational Competency Testing Institute (NOCTI) has been serving the career and technical education (CTE) community for almost 45 years. It is in the unique position to produce longitudinal data that indicates technical competence levels based on end-of-program testing across the country. NOCTI's data confirms that CTE is indeed…

This paper tests the external effect of household childbearing behavior by drawing on microfertility data from China. The test is executed by regressing one woman's fertility on the average fertility of neighboring women. China's unique affirmative birth control policy provides us with quasi-experimental fertility variation that facilities…

This article explores the configural weighted average (CWA) hypothesis suggesting that extension biases, like conjunction and disjunction errors, occur because people estimate compound probabilities by taking a CWA of the constituent probabilities. The hypothesis suggests a process consistent with well-known cognitive constraints, which…

Maintaining a safe, orderly learning environment is a significant challenge for education leaders, especially when students insist on bringing alcohol, weapons, and drugs into schools. To compound that challenge, educators who wish to uncover contraband must do so within the confines of the Fourth Amendment's prohibition against unreasonable…

A three-stage paradigm for telephonically assessing suicidal risk and triaging suicidal callers as practiced in an Employee Assistance Program Call Center was investigated. The first hypothesis was that the use of the procedure would increase the probability that callers would accept the clinician's recommendations, evidenced by fewer police…

Nanoscale science and engineering are disciplines that examine the unique behaviors and properties of materials that emerge at the size range of 1 to 100 nanometers (a billionth of a meter). Nanobiotechnology is a sub-discipline of nanoscience that has arisen more recently. Nanobiotechnology is already impacting the fields of healthcare and…

Compared to unidimensional item response models (IRMs), cognitive diagnostic models (CDMs) based on latent classes represent examinees' knowledge and item requirements using discrete structures. This study systematically examines the viability of retrofitting CDMs to IRM-based data with a linear attribute structure. The study utilizes a procedure…

Child development is accompanied by a robust increase in immediate memory. This may be due to either an increase in the number of items (chunks) that can be maintained in working memory or an increase in the size of those chunks. We tested these hypotheses by presenting younger and older children (7 and 12 years of age) and adults with different…

We tested the hypotheses derived from investment theory that quality of alternatives and institutional preference exert additive and interactive effects on institutional commitment in a sample of 1166 first-year college students at a large state university, who were surveyed within two weeks of the start of their first semester. As predicted, a…

We hypothesized that novel stimuli represent salient learning signals that can motivate "exploration" in search for potential rewards. In computational theories of reinforcement learning, this is referred to as the novelty "exploration bonus" for rewards. If true, stimulus novelty should enhance the reward anticipation signals in brain areas that…

This paper describes research on newborns' responses to music. Video observation and electroencephalogram (EEG) were collected to see whether newborns' responses to random sounds differed from their responses to music. The data collected were subjected to both qualitative and quantitative analysis. This paper will focus on the qualitative study,…

The main objective of this study was to compare pre-service English teachers' self-efficacy beliefs with the instructors' views of the teaching competence of these pre-service teachers. Thirty-nine student teachers (13 males and 26 females) and five female instructors participated in the study. For data collection, student teacher and instructor…

The major purpose of this study is to describe a conceptual framework for examining differential item functioning (DIF) and differential person functioning (DPF) as types of model-data misfit within the context of assessing students with disabilities. Specifically, DIF and DPF can be viewed through the lens of residual analyses. Residual analyses…

Differentiation of self, a cornerstone concept in Bowen theory, has a profound influence over time on the functioning of the individual and his or her family unit. This 5-year longitudinal study tested this hypothesis with 50 developing nuclear families. The dimensions of differentiation of self that were examined were goal direction and…

This article presents a comprehensive evaluation of the Pediatric Attention Disorders Diagnostic Screener (PADDS). PADDS was developed as a computer-based assessment system to screen for attention and executive function disorders in children aged 6 through 12 years. The evaluation of the PADDS indicated that it can be a useful and efficient…
