Mediation analyses are crucial for understanding the mechanisms through which interventions or theoretical constructs influence outcomes within nested structures, commonly found in education, psychology, and sociology. Recognizing the importance of these effects, designing and analyzing robust studies to detect them is essential. This dissertation…

Summary statistics and data visualizations are often used to explore data and draw preliminary conclusions. Although valuable, these tools do not always reveal the underlying patterns and trends in the data and can sometimes be misleading. We describe an approach for teaching the need for more advanced statistical analysis using multiple linear…

We study flexible Bayesian methods that are amenable to a wide range of learning problems involving complex high dimensional data structures, with minimal tuning. We consider parametric and semiparametric Bayesian models, that are applicable to both static and dynamic data, arising from a multitude of areas such as economics, finance and…

I examined the use of meditation practices among collegiate-level musicians (N = 255), along with the degree to which these practices contributed to music performance anxiety (MPA) when controlling for trait perfectionism and trait mindfulness. Findings indicated that approximately 48% of the participants sampled had engaged in meditation during…

This research connects several data-driven educational data mining approaches to a framework for interaction developed in educational research. In particular, 10 million usage data points collected by a Learning Management System used by students and teachers in 450 online undergraduate courses were analyzed with this framework. A range of…

This research study explored possible relationships of professional mental health counselors who have experienced a phenomenon called posttraumatic growth (PTG), which is a positive cognitive and emotional change that stems from surviving a traumatic life crisis. The current study aimed to investigate a connection of PTG in professional counselors…

The purpose of this study is to better understand the relationship among factors affecting social workers' overall readiness to respond to intimate partner violence (IPV) in a sample of recent MSW graduates (N = 205). Findings suggest MSW IPV education and postgraduate IPV training are significantly associated with perceived preparedness and…

Since the seminal work of Davis in 1989 produced the Technology Acceptance Model (TAM), researchers have sought to extend the framework and use the resulting models to describe the predictors of technology adoption specific to various populations. Although the TAM has been used to understand the adoption of technology in higher education, most of…

This study explored factors that predicted learners' transformative learning in an online employee training program in a higher education institution in the U.S. A multivariate multiple regression analysis was conducted with a sample of 74 adult learners on their learning of a new learning management system. Four types of participants' behaviors…

Anger regulation among adolescents is important to investigate given theoretical and empirical support for its critical association with peer relationships. This study examined two aspects of anger regulation (i.e., inhibition, dysregulation) using self-report and peer-nominations and their associations with social acceptance among 163 Black and…

Social work education stresses training students to understand oppressive structural barriers and promote social and economic justice. Social empathy, which is rooted in a deep understanding of those who are different from us through contextual understanding and macro perspective-taking, offers a framework for teaching social justice that…

As both universities and students demonstrate an increasing interest in offering and taking online courses, a better understanding of the causes of student outcomes, such as student achievement has become increasingly important. Exploring the causes of varying rates of student success in online courses of higher education is an ongoing challenge…

Entry into school represents as much a challenge for children as it does for their parents. The authors examined the ways in which transition practices help children and their families feel prepared for school entry, as measured by the child's emotional adaptation during the first days in class and the family's sense of being prepared for this…
