Understanding Public Library Services And Use: A Structural Equation Modeling Framework, Ian Burke

Electronic Theses and Dissertations

This dissertation describes the process of fitting publicly available data from the 2015 Public Libraries Survey and 2015 American Community Survey to a structural equation model based on a theory of action for public libraries relating operating revenue to latent factors measuring service availability and library use within the context of matched community demographic data. The process of using theory-based data analysis to investigate publicly-available data is examined. Key findings include acceptable estimates of goodness-of-fit for hypothesized factors representing public library service availability and public library use, an inconsistent mediation effect of service availability on the relationship between public library …

Assessment Of Multiple-Form Structure Designs Of Multistage Testing Using Irt, Hanan M. Alghamdi

Electronic Theses and Dissertations

The current study investigated multistage testing (MST) as an alternative to classical linear testing (CLT) for the General Aptitude Test (GAT). The aim was to assess the effects of two assembly methods (narrow vs. wide range—NR vs. WR), two routing methods (Defined Population Intervals—DPI— and the Approximate Maximum Information method—AMI), and two panel structures (two-stage and three-stage) on precision of ability estimates and accuracy of classification for both sections of the GAT (Verbal and Mathematics). Thus, eight conditions were examined and compared: 2 (assembly conditions) * 2 (panel structures) * 2 (routing methods).

The dataset that included a sample of …

Classification Of One-Year Student Persistence: A Machine Learning Approach, Ben Siebrase

Electronic Theses and Dissertations

Multilayer perceptron neural networks, Gaussian naïve Bayes, and logistic regression classifiers were compared when used to make early predictions regarding one-year college student persistence. Two iterations of each model were built, utilizing a grid search process within 10-fold cross-validation in order to tune model parameters for optimal performance on the classification metrics F-Beta and F-1. The results of logistic regression, the historically favored approach in the domain, were compared to the alternative approaches of multilayer perceptron and naïve Bayes based primarily on FBeta and F-1 score performance on a hold-out dataset. A single logistic regression model was found to perform …

Now You See Me: A Black Feminist Autoethnographic Poetic Polemic Of Radical Reflexivity And Critical Arts-Based Inquiry, Myntha Anthym

Electronic Theses and Dissertations

This dissertation is an autoethnographic poetic illness narrative based on the author's year-long ordeal with unrelenting undertreated chronic pain. The project is grounded in the epistemological tradition of Black Feminist Thought and presented in alignment with the emergent methodological paradigm of critical arts-based inquiry. The purpose of the project is for the author to develop and articulate a radical reflexive praxis within the paradigm of critical arts-based inquiry while demonstrating the value of lived experience as a source of knowledge and poetry as a method of inquiry in revealing subjugated truths about the experiences of marginalized people. The dissertation lives …

Examining The Role Of Liaison Librarians As Research Collaboration Partners: A Mixed-Methods Multiple-Case Study, Kawanna Michelle Bright

Electronic Theses and Dissertations

This sequential, mixed-methods study explored the professional relationship-building experiences of academic liaison librarians and university professors with a focus on research collaborations. A survey was administered and Chi-square and Spearman's rho analyses conducted on 2,650 responses to identify associations between organizational and individual factors and liaisons' work, perceptions of relationship-building experiences, and confidence in supporting faculty research. Following the survey, seven liaison-faculty pairs were identified and interviewed, and case study analysis utilized to explore specific liaison-faculty research collaboration relationships.

The study explored factors associated with liaisons' work, perceptions of faculty relationship-building, and confidence in supporting faculty research. The most salient …
