The focus of the present study is the use of complex noun groups, in the dissertations written 100 EdD and 100 PhD degrees in educational leadership. Four research questions were investigated: Research Question 1: What, if any, differences exist in the frequency of attributive adjectives that function as noun modifiers in the corpora of PhD and…

A slightly modified version of Lotka's mechanism that gives rise to sustained oscillations is shown to mimic observations of electrochemical oscillations reported during the dissolution of iron from iron electrodes in acidic media. The presentation of the modified mechanism includes only familiar chemical species and, in comparison to other…

Systematic reviews with meta-analyses are powerful tools that can answer research questions based on data from published studies. Ideally, all relevant data is directly available in the text or tables, but often it is only presented in graphs. In those cases, the data can be extracted from graphs, but this potentially introduces errors. Here, we…

Methods for indirect comparisons and network meta-analysis use aggregate level data from multiple studies. A very common, and closely related, scenario is where a company has individual patient data (IPD) from its own trial, but only has published aggregate data from a competitor's trial, and an indirect comparison of the treatments evaluated in…

We systematically review the concept and main characteristics of everyday creativity. First, we highlight the fact that a comprehensive definition of everyday creativity is still missing. The evidence reveals that the lack of a single approach for assessing everyday creative outcomes has led to an ambiguous understanding of this concept.…

Methods for group comparisons using predicted probabilities and marginal effects on probabilities are developed for regression models for binary outcomes. Unlike approaches based on the comparison of regression coefficients across groups, the methods we propose are unaffected by the scalar identification of the coefficients and are expressed in…

Introduction: There is considerable international research indicating health disparities between people with and without intellectual disabilities. It is important that comparative studies use representative population samples. This study compares a total administrative population of adults with intellectual disability to a random stratified…

Building on the original work of Bunker and Thorpe and their Teaching Games for Understanding (TGfU) approach to physical education, there is now a proliferation of Game Based Approaches (GBA) in the research literature (Bunker & Thorpe, 1982, A model for the teaching of games in secondary schools. "Bulletin of Physical Education,"…

Differential equations are an important mathematical concept used to model processes in many disciplines. However, the literature shows that students experience many difficulties when studying this topic. We investigate the effect of using context while teaching differential equations on engineering students' ability to construct and interpret…

To retrospectively explore the characteristics of plasma amino acids (PAAs) in children with autism spectrum disorder and their clinical association via case-control study. A total of 110 autistic and 55 healthy children were recruited from 2014 to 2018. The clinical phenotypes included severity of autism, cognition, adaptability, and regression.…

Understanding student cognitive states is essential for assessing human learning. The deep neural networks (DNN)-inspired cognitive state prediction method improved prediction performance significantly; however, the lack of explainability with DNNs and the unitary scoring approach fail to reveal the factors influencing human learning. Identifying…

This article explores the potential impact of Artificial Intelligence (AI) tools on Instructional Design (ID) workflows and organizations from a systems thinking perspective (Meadows, 2008). We provide an in-depth analysis of how three AI tools, ChatGPT, Midjourney, and Descript, can enhance efficiency in instructional design content creation…

Science, technology, engineering, and mathematics (STEM) fields are incredibly valuable to the world as innovations can help improve infrastructure and save lives. The United States has called for improvements in mentoring to help build a larger STEM workforce. Many studies and reports have focused on the experience of mentees within communities…

Post-instrument covariates are often included as controls in instrumental variable (IV) analyses to address a violation of the exclusion restriction. However, we show that such analyses are subject to biases unless strong assumptions hold. Using linear constant-effects models, we present asymptotic bias formulas for three estimators (with and…

HyFlex learning environments have been meeting the unique needs of students and institutions for nearly 20 years. However, it was the pandemic that gave HyFlex its widespread acceptance and application. Literature suggests that HyFlex may now be considered part of the new norm in education and therefore, further study is needed on how it affects…
