Two approaches for the statistical analysis of social network generation are widely used; the tie-oriented exponential random graph model (ERGM) and the stochastic actor-oriented model (SAOM) or Siena model. While the choice for either model by empirical researchers often seems arbitrary, there are important differences between these models that…

Research on the characteristics shown by children who cyberbully others is scarce. The objective of this research is to know the variables that predict the involvement of youngsters in cyberbullying perpetration. The current study examined the relation between socio-cognitive and emotional variables and cyberbullying perpetration. It examined the…

Summer break sets students in grades K-12 back by at least one month of instruction and has the strongest impact on mathematics retention. This study investigates whether there is evidence of the summer gap effect at the university level for engineering students enrolled in the introductory calculus course sequence, and possible demographic…

Including all children in large-scale educational studies is a pressing concern. Omitting certain types of children from studies can lead to skewed findings that promote inaccuracies about learning levels or educational quality. Increasingly, assessments are a method for investigating the quality of education systems, but national assessments are…

The observed increase in economic inequality, where the major concern is relative to the huge growth of the highest incomes, motivates to revisit classical measures of inequality and to offer new ways to synthesize the variability of the entire income distribution. The idea is to provide policy makers a way to contrast the economic position of the…

The Cattell-Horn-Carroll (CHC) model is a comprehensive model of the major dimensions of individual differences that underlie performance on cognitive tests. Studies evaluating the generality of the CHC model across test batteries, age, gender, and culture were reviewed and found to be overwhelmingly supportive. However, less research is available…

The objectives of this research were to compare the happiness and thinking styles of undergraduate students in the Physical Education and Sports Teaching Department and different departments, and to examine the relations between the students' happiness levels and their thinking styles. Using the correlational study design 661, undergraduate…

Purpose: Listening tests for emotion identification were conducted with 8-17-year-old children with hearing impairment (HI; N = 25) using cochlear implants, and their 12-year-old peers with normal hearing (N = 18). The study examined the impact of musical interests and acoustics of the stimuli on correct emotion identification. Method: The…

This study examined a sample of community college students from a diverse, large urban community college system in Texas. To gain a deeper understanding about the effects of background characteristics on student borrowing behaviors and enrollment outcomes, the study employed descriptive statistics and regression techniques to examine two separate…

In this study, the academic suspension levels of the students of the Faculty of Sports Sciences students and the Faculty of Education students in terms of age, gender, active sports making, department, graduated high school, mother education level, father education level, mother profession and father occupation variables have been examined. A…

Body mass index is a common proxy for proportion of body fat. However, body mass index may not classify youth similarly across ages and ethnicities. We used sex- and ethnic-specific receiver operating characteristic curves to determine how obesity classifications compared between body mass index and dual energy x-ray absorptiometry-based body fat…

The aim of the study is to investigate gender-bound language use in Turkish and English languages and to identify the differences and similarities across cultures and genders in the plays with family and social themes. Four English and five Turkish plays were chosen randomly for comparison. The number of words in the plays were taken into…

Researchers are often interested in establishing equivalence of population variances. Traditional difference-based procedures are appropriate to answer questions about differences in some statistic (e.g., variances, etc.). However, if a researcher is interested in evaluating the equivalence of population variances, it is more appropriate to use a…

Purpose: To characterize physical activity patterns among people with disabilities using data from a nationally representative health survey. Method: Individual-level data came from the Behavioral Risk Factor Surveillance System 2011 survey. Pearson's chi-squared tests were conducted to assess the difference in the proportion distribution of…

The purpose of the present study is to compare nonnormal distributions (i.e., t, skew-normal, skew-t with equal skew and skew-t with unequal skew) in growth mixture models (GMMs) based on diverse conditions of a number of time points, sample sizes, and skewness for intercepts. To carry out this research, two simulation studies were conducted with…
