Benjamin L. Edelman – ProQuest LLC, 2024
This dissertation is about a particular style of research. The philosophy of this style is that in order to scientifically understand deep learning, it is fruitful to investigate what happens when neural networks are trained on simple, mathematically well-defined tasks. Even though the training data is simple, the training algorithm can end up…

Piecewise latent growth modeling (PLGM) is a class of longitudinal models using a structural equation modeling framework to describe stage-like, discontinuous change of individuals over time. PLGM breaks the overall time window into non-overlapped segments where separate functions can be fitted to represent differential growth patterns for each…

Jordan Tait – ProQuest LLC, 2022
Once research questions are posed, researchers must answer many a priori questions regarding research design before analysis can be performed and any conclusions can be made, including sample selection criteria, data collection method, model specification, analysis and estimation technique. The choices made by researchers along this forking path…

Jungsun Go – ProQuest LLC, 2023
The purpose of this study was to investigate the effectiveness of four different models (bifactor, CTC(M-1), CTCU and unidimensional) as to optimal model selection when the wording effect associated with negatively worded items was present. A Monte Carlo simulation study was conducted to compare model-data fit and accuracy in parameter estimates…

Collins, Elizabeth I. – ProQuest LLC, 2023
There has been extensive research into the underrepresentation of minoritized students in STEM disciplines since the 1990s with limited success in improving the representation of Black women in math-intensive STEM fields. This dissertation aims to address how the guiding tenets of critical quantitative (QuantCrit) methods work when used with…

Beth A. Perkins – ProQuest LLC, 2021
In educational contexts, students often self-select into specific interventions (e.g., courses, majors, extracurricular programming). When students self-select into an intervention, systematic group differences may impact the validity of inferences made regarding the effect of the intervention. Propensity score methods are commonly used to reduce…

Kathleen V. McGrath – ProQuest LLC, 2021
School climate is a well-studied issue in educational research. However, surveys of school climate tend to be analyzed using item-centered as opposed to person-centered methods. The current study evaluated the 2018 South Carolina School Climate Survey using advanced applications of mixture modeling in an attempt to identify latent profiles at the…

Sheila Christine Mullooly – ProQuest LLC, 2022
Our institutional approaches to problems in the changing global landscape of internationalized higher education are being challenged, and many scholars call for new approaches for understanding and addressing the complex problems we face (e.g., la paperson, 2017; Lee, 2021; Patel, 2016; Stein, 2019, 2020). The COVID-19 pandemic has sped up the…

Dai, Shenghai – ProQuest LLC, 2017
This dissertation is aimed at investigating the impact of missing data and evaluating the performance of five selected methods for handling missing responses in the implementation of Cognitive Diagnostic Models (CDMs). The five methods are: a) treating missing data as incorrect (IN), b) person mean imputation (PM), c) two-way imputation (TW), d)…

Young, Jonathan – ProQuest LLC, 2017
Translational research (TR) is the process of bringing innovations from basic science into applied science, usually referring to the practice of medicine. It has been assumed that cross-disciplinary collaboration, or interdisciplinarity research (IDR), is essential to translation. Yet there is a gap in the literature regarding the interaction…

Santana, Carlos Gray – ProQuest LLC, 2016
This dissertation contains a collection of essays centered on the relationship between theoretical model-building and empirical evidence-gathering in linguistics and related language sciences. The first chapter sets the stage by demonstrating that the subject matter of linguistics is manifold, and contending that discussion of relationships…

Muldoon, Deirdre – ProQuest LLC, 2016
Three teachers and one assistant principal were recruited from a middle school in a large metropolitan area of the southwestern United States to implement evidence-based practices (EBP). The teachers implemented EBPs in self-continued classrooms to ameliorate the disruptive behavior of three students. The recruited teachers and assistant principal…
