The Graduate Record Examination And Graduate Admissions: Issues In Diversity, Lauren Rankin

Dissertations

Doctoral education is an expensive and difficult endeavor. Program faculty are interested in finding students who will be successful in completing their courses and obtaining employment. The Graduate Record Examination (GRE) is often used to assess a student’s readiness for the rigors of graduate education. A student’s readiness for doctoral education can be assessed through analyzing the predictive validity of the GRE with various outcomes such as grade point average, scholarly output, and time to completion. However, this measure may not predict success for all students with potential bias towards students who are international and linguistically diverse. A total of …

Hiv And Early Life Stress On Neuroimaging And Risky Behavior, Paola Garcia Egan

Dissertations

This study examined the interactive effects of early life stress (ELS) and HIV on brain morphometry, diffusion-basis-spectrum-imaging (DBSI), risky decision-making, and sex-risk behavior. 122 people with HIV (PWH) and 113 people without HIV (PWoH), free of major psychiatric illness and neurological confounds, were stratified into high (≥ 3 events) vs. low (< 3 events) ELS [PWoH/low ELS (n = 57), PWoH/high ELS (n =56), PWH/low ELS (n = 43), PWH/high ELS (n = 79)] and underwent structural magnetic resonance imaging, DBSI, neuropsychological, and risky-behavior assessment; all PWH were virologically controlled. Compared to PWoH, PWH had smaller orbitofrontal cortex (OFC), parietal lobes, insula, caudate and anterior cingulate. No ELS effects were detected in volumetric measures. Significant interactions were found between HIV serostatus and ELS on the OFC and on cellularity of the inferior fronto-occipital fasciculus after multiple comparisons adjustment. Specifically, PWH/high ELS exhibited significantly smaller OFC and PWoH/high ELS show significantly larger OFC than the other groups. PWoH/high ELS exhibited higher DBSI cellularity (neuroinflammation proxy) of the inferior-occipital-fasciculus compared to PWoH/high ELS. Regardless of HIV status, executive function moderated the relationship between the OFC and sex-risk behavior such that individuals within the sample who performed above average on a measure of executive function and had a larger OFC reported fewer sex partners in past six months than individuals with smaller volumes. No interaction was found between HIV serostatus and ELS on risky behavior measures. Clustering analyses defined ELS subgroups in PWH that were determined by demographic characteristics, duration of infection, recent CD4+ T-cell count, nadir CD4+ T-cell count and high/low ELS.Even in PWH that are virologically controlled, without major current psychiatric comorbidities, there is evidence of a synergistic impact of ELS and HIV on OFC volumes. Higher volumes in the OFC were detrimental when associated with lower executive function scores or advantageous when associated with higher executive function. Findings suggest that ELS is associated with different brain signatures among PWoH and virally suppressed PWH. However, ELS was not directly associated with risky behaviors, and subgroups in PWH were characterized by demographic variables, past substance use and HIV clinical variables.

In 27 open …

The Effects Of Segmenting Worksheets And Behavior Specific Praise On Independent Seatwork With Elementary Students, Lauren Peak

Dissertations

While the education system has seen many changes over the years due to COVID-19, one constant is that students must complete independent seatwork at certain times throughout the day. As teachers accommodate the many students in their classroom, an intervention that could increase students’ amount of academic production when doing independent seatwork would be mutually beneficial. For students, the increased contact with learning opportunities would provide the students means to increase fluency for that skill. Examining the effects of segmented and whole worksheets on production would, therefore, create additional learning opportunities.

This study sought to assess the effectiveness of the …
