"A priori" power analyses allow researchers to estimate the number of participants needed to detect any effects of an intervention. However, power analyses are only as valid as the parameter estimates used. Effect sizes vary greatly depending on several study characteristics, including the nature of the intervention, the developer of the…

Mediation in multi-level data can be examined using conflated multilevel modeling (CMM), unconflated multilevel modeling (UMM), or multilevel structural equation modeling (MSEM). A Monte Carlo study was performed to compare the three methods on bias, type I error, and power in a 1-1-1 model with random slopes. The three methods showed no…

This study analyzed the meta-data collected from a honeypot that was run by the Federal Bureau of Investigation for a period of 5 years. This analysis compared the use of existing industry methods and tools, such as Intrusion Detection System alerts, network traffic flow and system log traffic, within the Open Source Security Information Manager…

Prior research pertaining to the behaviors that related to the acceptance and use of technology was primarily focused on individual end users with little concentration on the collective organizational perspective. Infrastructure changes in organizations developed as they transitioned from serviceable information technology systems to enterprise…

Using data from a prospective population based study, the prevalence and psychopathological correlates of sibling bullying in children with and without autism spectrum disorder (ASD) were estimated. There were 475 children with ASD and 13,702 children without ASD aged 11 years. Children with ASD were more likely to be bullied by their siblings…

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…

This paper explores the student experience of multidisciplinarity within the undergraduate Geography curriculum. It considers the drivers that have underpinned this development before considering the findings of research into student experiences in two universities in the south of England. The results suggest that most students view this…

Contemporary research about purpose suggests that adolescents benefit in multiple ways when they develop purpose, and at the same time, that many adolescents are not purposeful. Adolescents in Catholic high schools may receive a unique set of contextual supports that help them develop a sense of purpose and understand what that purpose is. This…

This study records findings of a study carried out in a group of 100 students at a South African university. This study examines the group's assignments as a way of gathering evidence about pre-service teachers' achievements in the process of education and training. The empirical study was based on comparative analysis of scores obtained by…

The use of statistics in second language acquisition (SLA) research has increased over the past 30-40 years and continues to increase in both complexity and sophistication (Gass, 2009; Loewen & Gass, 2009). The increased use of statistical procedures has drawn attention to the current state of statistical literacy among second language (L2)…

Objective: To assess evidence of the effectiveness of school-based education programs for the prevention of child sexual abuse (CSA). The programs deliver information about CSA and strategies to help children avoid it and encourage help seeking. Methods: Systematic review including meta-analysis of randomized controlled trials (RCTs), cluster…

Although scholars have acknowledged the role of collaborative relationships of teachers in improving the quality of instruction, teacher collective efficacy continues to be a neglected construct in educational research. The purpose of this paper is to explore the relations between transformational school leadership, teacher self-efficacy and…

Early warning systems use school record data--such as attendance rate, behavior records, and course performance--to identify students at risk of dropping out. These are useful predictors of graduation-related outcomes, in large part because they indicate a student's level of engagement with school. However, these data do not indicate how invested…
