The Impact Of Sibling Sexual Abuse On Parenting Stress, Giuliana Berry

Theses and Dissertations

Sibling sexual abuse is the most common yet least reported, treated, and studied manifestation of child sexual abuse (Bertele & Talmon, 2023; Caffaro & Conn-Caffaro, 2005; Krienert & Walsh, 2011; O’Brien, 1991). It is a particularly challenging form of intrafamilial sexual abuse for parents and caregivers because their children are both the victim and the perpetrator of the abuse. They struggle to balance the needs of both children (Duane et al., 2002; Tener et al., 2020) and may experience heightened stress and associated psychological difficulties. Parenting stress is linked to child and adolescent posttraumatic stress and internalizing and externalizing problem …

Creating Systems Of Professional Learning To Encourage Deep Thinking In Social Studies: A Qualitative Study, Elizabeth Poda King

Theses and Dissertations

This paper describes a problem that developed due to a lack of systems in place to provide professional learning for teachers in social studies. This problem was ignited when revised standards were adopted which shifted from heavy content focus to skills and content. Standards requiring both skills and content encourage student inquiry and promote deep thinking by students through the use of historical evidence. Therefore, the purpose of the improvement science plan-do-study-act (PDSA) cycles was to develop a system of job-embedded professional learning to assist teachers with teaching strategies that use historical evidence to promote deep thinking in social studies …

The Design And Optimization Of Optical Systems For The Detection And Characterization Of Phytoplankton, Caitlyn M. English

Theses and Dissertations

Phytoplankton are among the smallest organisms found in marine and freshwater ecosystems. Despite their small size, phytoplankton play a vital role in sustaining life on Earth as primary producers. Through oxygenic photosynthesis phytoplankton are also responsible for large scale carbon fixation and oxygen production. The distribution of phytoplankton in a given water resource can exhibit a high degree of variability across time and space, and this is in large part due to their varying sensitivities to environmental conditions such as resource availability and grazing by predator organisms. As such, phytoplankton community structure is widely used as an investigative tool for …

Racial Contestations Of Space: Rural Preservation And Black Municipal Development In The South Carolina Lowcountry, Sydney Elizabeth Potter Smith

Theses and Dissertations

As newcomers flock to the South Carolina Lowcountry and drive development, the region has generally implemented strategies to preserve what remains of the region’s iconic rural landscapes by restricting new development in places that are designated as “Rural Areas”. These multi-scaler growth management strategies are problematic because they frame rural preservation as benefiting the greater good and prescribe a universal solution to urban sprawl, regardless of the individual needs of rural communities. This naturalizes and perpetuates forms of racial inequality across the landscape. Simultaneously, there are alternative spatial practices that aim to improve the quality of life for rural residents …

Limit Tests: Sociodemographic Representation In Public Organizations, Christopher Dee Eddy

Theses and Dissertations

Bureaucratic institutions are a critical yet often underappreciated nexus of democratic legitimacy. However, public agencies frequently fail to represent key constituencies of the American public, significantly influencing citizens' attitudes toward governing institutions and challenging effective governance. Research suggests that improving sociodemographic representation within political institutions can reinforce institutional support and citizen trust through symbolic processes and promote equitable policy outcomes through actions of bureaucrats from historically excluded groups.

Despite these insights, past research is divided on if, how, and when descriptive or passive representation leads to beneficial symbolic or active effects. While the existing body of representative bureaucracy theory offers …

Keep Your Head Up: An Examination Of Out-Of-School Literacy Practices In An Intergenerational Family System, Johnnie D. Bryant-Johnson

Theses and Dissertations

The asset-based qualitative study used a phenomenological approach within a Community Cultural Wealth framework to question the practices of an intergenerational family system in the Southeastern United States. The study investigated the family system’s out-of-school literacy practices and the exposure to culturally relevant literature. The study revealed that an elder who actively participated in rearing school-aged children intentionally introduced culturally relevant literature. Similarly, the study revealed that the primary caregivers did engage their school-aged children in conversations related to social justice and introduced them to culturally relevant texts. However, a child's inquiry into the topic initiated primary caregivers’ introduction to …

Bayesian Joint Modeling Of Longitudinal Data And Interval-Censored Failure Time Data, Yuchen Mao

Theses and Dissertations

Longitudinal data are a collection of repeated observations of the same subjects at different points in time. Interval-censored data arise when the time to the event of interest for each subject is never exactly observed but known to fall between two consecutive points in time. Joint analysis of longitudinal data and interval-censored failure time data can lead to more accurate estimates compared to separate modeling when the correlation among events of interest or intracluster correlation is present. The aim of this dissertation is to develop efficient and reliable joint analyses of longitudinal and interval-censored failure time data using Bayesian methods. …

The Impact Of Equity Literacy In Understanding, Creating, And Sustaining An Equitable School Climate, Kristen M. Ewing

Theses and Dissertations

There is an extraordinary culturally and linguistically diverse student population in America today; however, there is an overwhelmingly homogenous representation in educators, being predominantly White, middle-class, female, and monolingual (Howard, 2020; Tanase, 2020). The racial disparity between educators and students has serious consequences for marginalized students leaving many students undereducated and unprepared to compete in the world today (Howard, 2020). hooks (1994) claimed that educators are poorly prepared to confront diversity and we must focus on diversity and inclusion if we want to be more equitable and close the achievement gap. This qualitative action research study was centered around the …

The Effect Of Lexical Characteristics On Speech Pausing For People With Broca's Aphasia, Anna Kathryn Walker Smith

Theses and Dissertations

This study examines the connection between speech pause patterns and the lexical characteristics of the words that follow. Speech samples of 16 people with moderate Broca's aphasia and 16 age-matched neurologically healthy controls were evaluated in terms of word length, word frequency in the English language, syntactic category, and articulatory complexity. In general, people with aphasia (PWA) produced pauses more frequently before monosyllabic, very high frequency words with lower articulatory complexity, most of which were content words. The length of these pauses did not significantly correlate with any of the lexical factors examined in this study. The control group had …

Hybrid Bermudagrass Drought Tolerance In A Cool-Season Climate, Ashley J. Beazer

Theses and Dissertations

Kentucky bluegrass (Poa pratensis L.) (KBG) is the most commonly grown cool-season C3 turfgrass. However, as global temperatures rise, KBG struggles to tolerate higher temperatures, leading to increased irrigation demands--a growing concern in arid and semi-arid regions facing escalating drought conditions. In contrast, hybrid bermudagrass (HBG; Cynodon dactylon [L.] Pers. x Cynodon transvaalensis Burtt Davy), a warm-season C4 grass, has demonstrated promising adaptability in traditionally cool-season climates. Since 2008, HBG has been successfully grown with minimal winterkill in Provo, UT, USA, and is now being considered for broader adoption in similar climates. Two separate studies were conducted to evaluate the …

Assessing The Impact Of Internal Flow Dynamics On Detection Region Concentrations Of Low-Cost Optical Particle Counters, Livingstone Quarshie

Theses and Dissertations

Particulate matter (PM) poses significant risks to human health and the environment, making accurate measurement essential for exposure assessment and regulatory decisions. While traditional reference methods provide reliable data, they are often bulky, expensive, and difficult to maintain. Optical Particle Counters (OPCs) offer a cost-effective alternative, commonly used in clean rooms, residential spaces, and personal exposure monitoring. These devices rely on light scattering to measure PM concentrations. However, low cost OPCs face challenges related to calibration and measurement accuracy, requiring careful performance evaluation. This study used computational fluid dynamics (CFD) tools, CONVERGE Studio and ANSYS Fluent, to simulate a simplified …

The Right To Gender-Affirming Care, Justin J. Soulas

Theses and Dissertations

As of recent, twenty-four states have enacted bans on gender-affirming care, restricting minors from accessing medically necessary treatment. Existing scholarship has begun to explore the profound impact of these bans on transgender youth, their parents or guardians, and the medical professionals who support them. However, the body of literature on this rapidly evolving issue remains limited. This thesis aims to fill that gap by offering a legal defense of gender-affirming care, grounded in judicial precedent. It argues that parental rights to make medical decisions for their children—recognized in constitutional jurisprudence—extend to decisions involving gender-affirming treatment. Additionally, it draws on anti-discrimination …
