Many current theories and models include creativity as a component of giftedness, conceptualizing the construct in numerous ways that complement giftedness. Variations in creativity have also been studied among different academic disciplines, suggesting that although there may be higher levels of creativity for some, major choice is a complex…

Terrorism is a complex and evolving phenomenon. In the past few decades, we have witnessed an increase in the number of terrorist incidents in the world. The security and stability of many countries is threatened by terrorist groups. Perpetrators now use sophisticated weapons and the attacks are more and more lethal. Currently, terrorist incidents…

Educator evaluation is of significant interest and concern for all members of the national school community. School-based speech-language pathologists (SLPs), share these sentiments with their classroom counterparts. Frequently included in such evaluation systems, it is of concern to the SLP community that research documenting how school-based…

The purpose of the study was to determine if significant relationships existed among measures of elementary principals' leadership practices and measures of teacher self-efficacy as perceived by rural elementary teachers. Teachers' sense of efficacy has been related to teacher performance and student achievement. Teachers who have a strong sense…

This study provides the results of a latent class analysis (LCA) using data from the Trends in International Mathematics and Science Study -- 2011 (TIMSS-2011) with a focus on the 8th grade mathematics section. The study presents the analysis of item data with Mplus 7.31 to determine if results obtained yielded distinct latent subgroups. The data…

This article proposes a methodology for measuring institutional diversity and applies it to Ontario's university sector. This study first used hierarchical cluster analysis, which suggested there has been very little change in diversity between 1994 and 2010 as universities were clustered in three groups for both years. However, by adapting…

To further understand the properties of data-generation algorithms for multivariate, nonnormal data, two Monte Carlo simulation studies comparing the Vale and Maurelli method and the Headrick fifth-order polynomial method were implemented. Combinations of skewness and kurtosis found in four published articles were run and attention was…

This review introduces classical item response theory (IRT) models as well as more contemporary extensions to the case of multilevel, multidimensional, and mixtures of discrete and continuous latent variables through the lens of discrete multivariate analysis. A general modeling framework is discussed, and the applications of this framework in…

The purpose of this study was to determine the metacognitive skill levels and motivation of preservice chemistry teachers and to investigate the effect of different metacognitive skill levels on their motivation. The study was conducted during 2014-2015 spring semester. In this research, survey method was used to reveal the effect of different…

Realistic response rate expectations are important for successfully allocating and managing data collection efforts under limited resources. Interviewer performance is often evaluated against response rate standards, and face-to-face interviewer performance can vary due to, in part, the socioeconomic characteristics of the neighborhoods in which…

Purpose: This study obtained judgments of sentence intelligibility using orthographic transcription for comparison with previously reported intelligibility judgments obtained using a visual analog scale (VAS) for individuals with Parkinson's disease and multiple sclerosis and healthy controls (K. Tjaden, J. E. Sussman, & G. E. Wilding, 2014).…

This article examines whether the 7 abilities found in a previous study carried out by the authors to constitute fraction understanding of sixth grade elementary school students determine hierarchical levels of fraction understanding. The 7 abilities were as follows: (a) fraction recognition, (b) definitions and mathematical explanations for…

This paper reports in part on a major study, carried out in 2013, in which data were collected from university senior executives and academics in the five university business schools in the North East of England: it focuses on the quantitative findings produced. Whilst prima facie evidence would suggest that universities are strategically…

Children with autism spectrum disorder (ASD) are at high risk for sleep disturbance and behavioral dysregulation. However, the relationships between these difficulties are not fully understood. The current study examined the relationships between specific types of sleep and behavioral problems among 81 children with ASD. Sleep problems were…

To describe and facilitate the identification of child school behavior patterns, we developed a typology of child school behavior (ages 6-11 years) using the norming data (N = 2,338) for the second edition of the Behavior Assessment System for Children Teacher Rating-Child form). Latent profile analysis was conducted with the entire data set,…
