In this study, it is aimed to investigate the effects of various factors on the performance of the methods used in the determination of differential item functioning (DIF) in the DINA model included in the Cognitive Diagnosis Models. The current study is limited with Logistic Regression and Wald test methods which were used to determine the…

Methods to generate random correlation matrices have been proposed in the literature, but very few instances exist where these correlation matrices are structured or where the statistical properties of the algorithms are known. By relying on the tetrad relation discovered by Spearman and the properties of the beta distribution, an algorithm is…

Innovation is important to organizations' long-lasting success, yet many organizations fail to successfully promote innovation. One factor likely to bear an important influence on whether an organization successfully innovates, but that has received relatively little research attention, is the personality of the CEO. The present research examines…

Purpose: This review article provides a scoping review of the literature on mathematical abilities in developmental language disorder (DLD). Children with DLD typically struggle with learning in school; however, the mechanism by which DLD impacts academic success is unclear. Mathematics involves demands in the multiple domains and therefore holds…

Tendencies to marketization and privatization in higher education, along with other factors, have challenged the idea of higher education as a public good in many countries over the years. China has experienced this situation to some extent. During the last 20 years, this has triggered various discussions on higher education and public good(s) in…

The Vale and Maurelli algorithm is a widely used method that allows researchers to generate multivariate, nonnormal data with user-specified levels of skewness, excess kurtosis, and a correlation structure. Before obtaining the desired correlation structure, a transitional step requires the user to calculate the roots of a cubic polynomial…

Many psychometric measures yield data that are compatible with (a) an essentially unidimensional factor analysis solution and (b) a correlated-factor solution. Deciding which of these structures is the most appropriate and useful is of considerable importance, and various procedures have been proposed to help in this decision. The only fully…

Accounts of the creative process tend to be retrospective and implicitly ground the creative act within the person, the mind, the moment, the idea; in doing so, they often miss the larger sociomaterial qualities that can provide us with important insights about the social relationality and playfulness of the creative process. In this article, we…

Shyness has been found to have a negative impact on creativity. However, little attention has been given to the underlying process of the relationship between shyness and creativity. On the basis of literature, we hypothesize that shyness has an indirect impact on creativity through creative process engagement. Two studies were conducted on…

Previous studies of individual differences have revealed strong correlations between children's vocabulary and grammatical abilities, and these data have been used to support theoretical accounts positing direct developmental relations between these two areas of language. However, between-person differences do not necessarily reflect…

What is engineering? What do engineers do? How is engineering related to, but distinct from, science? These questions all relate to the nature of engineering (NOE), and as engineering is incorporated into K-12 education across the United States, the NOE is becoming increasingly important for students and teachers. While many policy documents call…

Large-scale surveys have pointed to considerable country variations in the prevalence and nature of bullying victimisation. In seeking to explain these, one possible explanatory factor has been the cultural values of a country, such as expounded by (Hofstede 1980; Hofstede et al. 2010). Of his six dimensions of cultural values, the most…

Objective: Maladaptive daydreaming (MD) is characterized by vivid, excessive fantasy activity that becomes prioritized over other activities and may result in avoidant coping strategies. Little is known about the relationship between MD and internalized stigma in the neurodivergent sample. The current study aimed to examine emotional…

The assessment of English speaking in EFL environments can be inherently subjective and influenced by various factors beyond linguistic ability, including choice of assessment criteria, and even the rubric type. In classroom assessment, the type of rubric recommended for English speaking tasks is the analytical rubric. Driven by three aims, this…

Introduction: Prescription stimulants are an effective FDA approved treatment for attention deficit hyperactivity disorder (ADHD) however their safety has come under scrutiny. Multiple studies demonstrate safe use in pediatric populations, but prescriptions are increasing to adults and it is not evident which comorbidities might place people at…
