Developing latent constructs of dialogic interaction to examine the epistemic climate: Rasch modeling

This chapter presents an introductory overview of concepts that underscore the general framework of item response theory. “Item response theory” is a broad umbrella term used to describe a family of mathematical measurement models that consider observed test scores to be a function of latent, unobservable constructs. Most musical constructs cannot be directly measured and are therefore unobservable. Musical constructs can therefore only be inferred based on secondary, observable behaviors. Item response theory uses observable behaviors as probabilistic distributions of responses as a logistic function of person and item parameters in order to define latent constructs. This chapter describes philosophical, theoretical, and applied perspectives of item response theory in the context of measuring musical behaviors.

Mediating Mechanisms

We tested the Youth Physical Activity Promotion (YPAP) framework on Romanian students in order to identify actionable determinants to support participation in physical activity. Our sample consisted of 665 responses to an online survey, with participants aged 18–23 (mean = 19 years); 70% were women. We used the partial least squares algorithm to estimate the relationships between students’ behavior and possible predictors during the COVID-19 pandemic. Our results indicate that all the theoretical dimensions of YPAP (predisposing, enabling and reinforcing) have a positive and significant impact on physical activity, with two mediating mechanisms expressed as predisposing factors: able and worth. Unlike previous research, we used second-order latent constructs, unveiling a particular structure for the enabling dimension that only includes sport competence, fitness and skills, but not the environmental factors.

Managerial Innovation

Companies in South Africa should realise the important influence of greening their suppliers and of innovation to achieve environmental goals and competitive advantages. In order to prove this, a questionnaire survey was conducted with 75 companies from 11 industries in the City of Johannesburg Metropolitan Municipality region, South Africa. A confirmatory factor analysis was done, followed by bivariate correlations to determine the strength of association between the latent constructs. Correlations between greening the supplier, innovation, environmental performance and competitive advantages were done. The research found that a green innovative process had a significant effect on environmental performance. Green managerial innovation further had a significant correlation with competitive advantage. The primary result of the study indicated that all the constructs positively related to each other, meaning that greening suppliers, by means of green innovation, leads to an enhanced environmental performance and to competitive advantages.

Computer Based

In this article, we describe an exercise in instrument selection applicable to both undergraduate and graduate courses. The exercise consists of 5 progressive steps that involve choosing and defining a theoretical construct (Steps 1 and 2), using computer-based technology to obtain 2 distinct instruments that measure this construct (Steps 3 and 4), and comparing and contrasting these 2 instruments along multiple dimensions (Step 5). This activity generates awareness of the issues involved in measuring latent constructs and teaches at least 3 lessons: (a) The 1st step to accurate instrumentation is precisely conceptualizing the construct of interest; (b) there is more than 1 way to measure latent constructs, and these multiple approaches should be compared; and (c) it is crucial to measure a construct in a way that best matches its underlying definition.
