Outcome Measures Or Graduation Rates, That Is The Question, Miran Kang May 2024

Outcome Measures Or Graduation Rates, That Is The Question, Miran Kang

Graduate Theses and Dissertations

The study compared the Outcome Measures (OM) to the traditional Graduation Rates (GR) to ascertain if OM portrayed the performance of higher education institutions differently than GR and to determine which of the two metrics aligned better with accountability policy objectives. GR refers to the percentages of first-time, full-time students who obtain a degree or certificate within 150% of the normal time. OM presents the award status of all degree/certificate-seeking undergraduate students on four cohorts: first-time, full-time (FTFT); first-time, part-time (FTPT); non-first-time, full-time (NFTFT); and non-first-time, part-time (NFTPT). OM was a more comprehensive indicator than GR, particularly for 2-year institutions, …


Examining Eight-Year Bachelor’S Degree Completion Rates For U.S. Institutions Offering Competency-Based Education And Comparable Traditional Institutions, Gray Carpenter Church May 2024

Examining Eight-Year Bachelor’S Degree Completion Rates For U.S. Institutions Offering Competency-Based Education And Comparable Traditional Institutions, Gray Carpenter Church

Graduate Theses and Dissertations

Competency-based education (CBE) is a learner-centric framework that emphasizes what students “know and can show” more than how much time they spend in the classroom. CBE advocates claim that by allowing students to take as little or as much time as they need to demonstrate their mastery of course competencies, students develop higher levels of proficiency and are better prepared to enter the workforce. Despite having been in existence for decades, CBE has not been widely adopted in postsecondary education, and studies of CBE as a viable alternative to traditional methods of education remain scarce. The purpose of this cross-sectional …


Does Diversity Ideology Moderate Participants’ Perceptions Of Therapists Who Do And Do Not Broach?, Emily Allen May 2024

Does Diversity Ideology Moderate Participants’ Perceptions Of Therapists Who Do And Do Not Broach?, Emily Allen

Graduate Theses and Dissertations

Introduction. The literature has grown considerably regarding the act of broaching racial, ethnic, and cultural factors in therapy. Many have highlighted its positive impact on the therapeutic alliance, but little empirical work explores how individual differences influence a client’s response to broaching. This study assessed the effects of participant diversity ideology and therapist broaching behavior on perceptions of a therapist’s effectiveness. I hypothesized that participants in the therapists broaching condition would perceive the therapist to be more effective than participants in the no broaching condition. I also hypothesized that participants’ colorblind diversity ideology and therapist broaching condition would interact, such …


Generalizations Of The Hardy Spaces And The Schwarz Boundary Value Problem, William L. Blair May 2024

Generalizations Of The Hardy Spaces And The Schwarz Boundary Value Problem, William L. Blair

Graduate Theses and Dissertations

We prove that many of the boundary properties associated with functions in the classic holomorphic Hardy spaces on the complex unit disk are present in Hardy classes of solutions to certain nonhomogeneous Cauchy-Riemann equations and higher-order generalizations of these equations. Also, we explicitly solve generalizations of the Schwarz boundary value problem on the complex unit disk and the upper-half plane when the boundary condition is in terms of boundary values in the sense of distributions.


The Effect Of Gentle Yoga On Average Daily Step Count, Francesca D'Agrosa May 2024

The Effect Of Gentle Yoga On Average Daily Step Count, Francesca D'Agrosa

Graduate Theses and Dissertations

While walking is a widely accessible form of exercise that is highly effective at increasing overall wellness (Kadir et al., 2019; Zhao et al., 2015) and is a recommended form of physical activity for overweight and obese individuals, studies still indicate low step counts and levels of physical activity in people with obesity (Shultz et al., 2011). Sedentary overweight individuals may avoid walking for several reasons, including physiological and/or biomechanical factors that make walking more difficult. This study attempted to explore and address these avoidant behaviors by employing a single-case ABAB reversal design to implement bi-weekly gentle yoga sessions over …

Developing Anisotropic Soft Matter As Functional Materials To Interface With Biological Systems, Homa Ghaiedi May 2024

Developing Anisotropic Soft Matter As Functional Materials To Interface With Biological Systems, Homa Ghaiedi

Graduate Theses and Dissertations

Liquid crystals (LCs) constitute a subset of soft matter possessing hybrid characteristics from both liquid and crystalline phases. In this state, the center of masses remains uncorrelated similar to an isotropic phase, while the long axis of molecules aligns in parallel, resulting in molecules exhibiting orientational and positional order, either individually or concurrently. The directional alignment inherent in LCs arises from the asymmetrical shape and structure of the constituent molecules, causing a spontaneous self-assembly into ordered phases. This cooperative molecular behavior manifests distinctive optical features when subjected to cross polarizers. The remarkable sensitivity of LCs to external stimuli, including temperature, …

The Role Of The Patterning Cascade Model In Human Mandibular Premolar Variation, Molly Militello May 2024

The Role Of The Patterning Cascade Model In Human Mandibular Premolar Variation, Molly Militello

Graduate Theses and Dissertations

Human mandibular premolars represent a morphologically transitional tooth class, possessing a relatively caniniform third premolar (P3) and a more molariform fourth premolar (P4). Marked variation in cusp height and lingual cusp number are characteristics unique to these postcanine teeth. The aim of this study is to determine if human premolar variation aligns with predictions outlined by the patterning cascade model (PCM). The PCM posits that tooth size and enamel knot spacing/surrounding inhibitory fields (approximated by cusp tip positioning) play a role in determining ultimate crown morphology, providing a predictive framework for examining crown variation within and between individuals. While there …
