The central roles of science in the field of remedial and special education are to (a) identify basic laws of nature and (b) apply those laws in the design of practices that achieve socially valued outcomes. The scientific process is designed to allow demonstration of specific (typically positive) outcomes, and to assist in the attribution of…

Qualitative and multimethod scholars face a wide and often confusing array of alternatives for case selection using the results of a prior regression analysis. Methodologists have recommended alternatives including selection of typical cases, deviant cases, extreme cases on the independent variable, extreme cases on the dependent variable,…

Translational research (TR) is the process of bringing innovations from basic science into applied science, usually referring to the practice of medicine. It has been assumed that cross-disciplinary collaboration, or interdisciplinarity research (IDR), is essential to translation. Yet there is a gap in the literature regarding the interaction…

Objective: Conduct a scoping review of food and alcohol disturbance (FAD) in US college students to overview the literature within this population and identify research opportunities. Methods: Studies (n = 39) were selected using systematic searches of databases and references. Search terms included: drunkorexia, "food and alcohol…

Whether selection processes contribute to group-level disparities or merely reflect pre-existing inequalities is an important societal question. In the context of observational data, researchers, concerned about omitted-variable bias, assess selection-contributing inequality via a kitchen-sink approach, comparing selection outcomes of…

This study investigates the relationship between the designated research project system independent variables of Labor, Travel, Equipment, and Contract total annual costs and the dependent variables of both the associated matching research project total annual academic publication output and thesis/dissertation number output. The Mahalanobis…

This article reports on a study of six Grade 11 learners' levels of understanding of concepts related to the function definition and representation. Task-based clinical interviews were used to elicit the learners' interpretations and reasoning when working with these function-related concepts. Indicators for Action-Process-Object-Schema (APOS)…

Multisite trials, in which individuals are randomly assigned to alternative treatment arms within sites, offer an excellent opportunity to estimate the cross-site average effect of treatment assignment (intent to treat or ITT) "and" the amount by which this impact varies across sites. Although both of these statistics are substantively…

This study examined how specific guidelines and heuristics have been used to identify methodological rigor associated with single-case research designs based on quality indicators developed by Horner et al. Specifically, this article describes how literature reviews have applied Horner et al.'s quality indicators and evidence-based criteria.…

The acceptance of new growth theory relates, in part, to a number of highly touted regional success stories--or what I term "Knowledge Based Economic Areas" (KBEAs) in this and past essays. The United States, and California in particular, is viewed as perhaps the most robust creators of KBEAs, providing an influential model that is…

Exploratory Factor analysis is a research tool that can be used to make sense of multiple variables which are thought to be related. This can be particularly useful when a qualitative methodology may be the more appropriate method for collecting data or measures, but quantitative analysis enables better reporting. This case first gives a brief…

The purpose of this study, with reference to Community of Inquiry, is to evaluate the comparative effectiveness of Learning activities based on Online Inquiry differentiating as Open and Guided Inquiries. This study employs mixed research method and explanatory design. The data were collected with the Community of Inquiry Index and the Student…

Little attention has been paid to understanding faculty-student productivity via undergraduate research from the faculty member's perspective. This study examines predictors of faculty-student publications resulting from mentored undergraduate research, including measures of faculty-student collaboration, faculty commitment to undergraduate…

Pregnancy is relatively a distinct research area given the perception of positive lifestyles mothers follow during their pregnancy. While the assumption may have validity, complications do occur during pregnancy and childbirth. It is predicted that every 4.5 minutes an infant is born with a birth defect, and, on average, 1 in 33 infants are born…

The central aim of this study was to investigate how different countries practice social and emotional education (SEE) using a comparative research design to create a cross-cultural conceptual framework. The study used a sequential quantitative-qualitative analysis with a comparative design that included 750 teachers. Cross-cultural differences…
