Theses and Dissertations--Chemical and Materials Engineering

Decades of use of per- and polyfluoroalkyl substances (PFAS) in a multitude of consumer and industry-based products have led to a devastating amount of soil and water contamination. Although these chemicals and compounds possess advantageous qualities – such as that of PFAS in the role of fire-fighting foams that have no doubt saved countless lives and homes, we must take responsibility for the anthropogenic hazards that threaten our global health. This entails being able to cost-effectively remediate problems created in the past from overuse of toxic substances that could negatively impact our future, and in this case, the future of …

Developing And Modeling Tunable Nanofiltration And Functionalized Membranes For The Separation Of Organics And Inorganics From Water: Per- And Polyfluoroalkyl Substances, Lanthanides, And More, Francisco Cecil Leniz-Pizarro

Theses and Dissertations--Chemical and Materials Engineering

In a world where clean water predictability is challenged by both global warming and the contamination of our natural resources, it is our responsibility to advance water separation technologies into more efficient processes and to lessen their environmental footprint. Pore and surface functionalization of membranes can enhance the separation of ions from water and even help overcome intrinsic challenges that some current separation technologies possess. If we begin with a complete fundamental understanding of the nanoscale interactions that occur in the process of separating ions from water, then we can engineer new functionalized composite membranes to provide alternative processes keeping …

Solid-State Electrolytes For Long Duration Molten Sodium Batteries, Ryan C. Hill

Theses and Dissertations--Chemical and Materials Engineering

Rechargeable batteries have become a staple of modern society, driving the development and expansion of portable electronics and electric vehicles. The long lifetime and high energy density provided by batteries have made them excellent candidates for use in the emerging field of long duration, grid-scale energy storage. However, traditional battery chemistries, such as Li-ion, are not an ideal solution for grid-scale storage, due to high-cost raw materials that are often sourced from volatile markets. Sodium-based batteries are a promising alternative for long duration storage, owing to the domestic abundance of raw materials and energy densities that nearly rival that of …

Leveraging Cell-Substrate Adhesion And Cell Migratory Properties In Skeletal Muscle Constructs And Cancer Metastasis Assays, Lauren E. Mehanna

Theses and Dissertations--Chemical and Materials Engineering

Volumetric muscle loss (VML) remains one of the few skeletal muscle injuries without a reliable and repeatable treatment. In large volume muscle injuries, muscle fibers as well as the surrounding connective tissue are damaged, preventing therapeutic muscle stem cells, called myogenic progenitor cells (MPCs), from reaching the injury site and initiating repair. There is a clinical need to rapidly fabricate in vitro muscle tissue constructs that mimic the native tissue organization, with aligned myotubes, for insertion and integration at the patient’s injury site. In this dissertation, we utilize the MPC’s natural propensity to close gaps across an injury site to …

Surface Modification Of Carbon-Based Electrodes For Electrochemical Conversion Processes: Oxygen Reduction Reaction And Bicarbonate Conversion, Udari Shyamika Kodithuwakku Arachchige

Theses and Dissertations--Chemistry

Oxygen reduction reaction (ORR) and conversion of bicarbonate into value-added chemicals are two significant electrochemical processes for energy storage and conversion. ORR is an important electrochemical reaction in fuel cells and metal-air batteries that provide power conversion and storage capacity, respectively, for portable electronics, and electric vehicles. However, the performance of catalysts (e.g., platinum-based) is critically limited by slow kinetics, inefficient four-electron pathway, and surface deactivation. This limited performance of platinum-based catalysts, the scarcity of platinum, and vulnerable supply chains for critical minerals require the development of alternative electrocatalysts now more than ever. Carbon-based materials possess several key properties that …

Investigating Ru(Ii) Anticancer Agents With Non-Canonical Mechanisms Of Action, Richard Joseph Mitchell

Theses and Dissertations--Chemistry

Platinum(Pt)-based agents are used in approximately 50% of all cancers that are treated with chemotherapy. Unfortunately, the dose-limiting toxicity of these agents remains problematic for patients undergoing treatment. Additionally, Pt(II) therapeutics suffer from transporter-dependent uptake, limited chemical functionalization, and high susceptibility to inactivation by free thiols within the cytosol. Developing small molecules with non-canonical mechanisms of action is one strategy that can be employed to circumvent these limitations. Utilization of coordination complexes with ruthenium(Ru) metal centers is one attractive strategy. Ru(II) compounds are often octahedral, facilitating greater accessibility for chemical diversity; Ru(II) complexes use passive transport and transferrin-mediated transport for …

Just Because We Are Black: Exploring The Impact Of Racial Trauma On African American Adults And Introducing An Approach To Assessment, Charessa L. Mcintosh

This Is Who I Am: Identity Development And Importance Among Diverse Youth From Lgbtq+ Parent Families, Madison T. Diomede

Theses and Dissertations--Psychology

Although the literature on identity and related constructs among adolescents, emerging adults, and diverse populations is growing, little research has investigated identity among adolescents and emerging adults specifically in the context of LGBTQ+ parent families. The present study seeks to fill this gap in the literature by qualitatively investigating identity development and importance among diverse youth with LGBTQ+ parents. Participants are 51 youth (ages 12-25 years) with at least one LGBTQ+ parent. Trained personnel conducted remote, audio-recorded, semi-structured interviews from December 2018-February 2020. Interviews included questions about participants’ individual identities and conversations they have had with their parents about those …

Prenatal Ethanol Exposure Impairs Performance On Spatial And Tactile Sequential Discrimination Task In Juvenile Rats, Caleb S. Bailey

Theses and Dissertations--Psychology

Fetal alcohol spectrum disorders (FASDs) are a set of cognitive and behavioral abnormalities that arise in ~5% of children who have been prenatally-exposed to alcohol. Prenatal alcohol exposure (PAE) can cause impairments in learning acquisition, working memory, response inhibition, and attentional-set shifting that result in exaggerated deficits in executive function and impairments in goal-seeking behavior. There are standard procedures used in rodent research to address some components of these deficits, but few procedures are sensitive enough to comprehensively assess such deficits. To address this issue in FASDs research techniques, we developed a procedure that requires prolonged executive function in a …

Effect Of Menstrual Cycle Phase On The Rewarding Properties Of Alcohol In Women, Annie K. Griffith

Theses and Dissertations--Psychology

Compared with men, women are disproportionately affected by alcohol, including greater risks of behavioral impairment and relapse. One likely mechanism underlying this disparity is fluctuations of ovarian hormones, particularly estradiol (E2), across phases of the menstrual cycle. Pre-clinical and clinical studies have shown that higher E2 levels correlate with heavier patterns of alcohol consumption, suggesting E2 may modulate drinking. This relationship is thought to be mediated by the rewarding properties of alcohol. The present thesis tested the hypothesis that elevated E2 during the late follicular phase would increase the rewarding properties of alcohol. Fifty young-adult women participated in a within-subjects …

Ethanol Decreases Expression Of Developing Neurons, But Not Neuronal Viability, In A Cultured Rat Hippocampus, Cassidy Count

Theses and Dissertations--Psychology

As of 2019, alcohol use disorders (AUDs) affect roughly 14.1 million individuals over the age of 18 and cost up to $249 billion in economic burden in the United States. In addition to central nervous system (CNS), those affected by AUDs can present with cognitive and behavioral abnormalities. Specifically, those affected by AUDs experience deficits in memory consolidation and retrieval as well as executive functioning, which may be due to cellular changes within the hippocampus. There are at least two prominent and contended theories which explain the mechanism of functional impairment caused by alcohol: 1) alcohol induces excitotoxic neuronal death …

Personalized Longitudinal Network Models Of Alcohol Use: A Mechanistic Approach, Stephen Semcho

Theses and Dissertations--Psychology

AUD and high-risk drinking are significant public health concerns, and prevailing diagnostic models fail to account for the within-person variability in AUD presentation and the role of functional mechanisms that maintain drinking outcomes. The ETOH Framework highlights the importance of three primary superdomains that maintain and characterize AUD – reward salience, cognitive dyscontrol, and negative emotionality. The current study was the first attempt to investigate the role of the primary ETOH mechanisms, along with positive and negative affect, on alcohol use outcomes, using a novel approach to model individual-level networks of relations over time. This study gathered twice-daily diary data …

The Condom Use Outcomes And Sexual Functioning Of Young Adult Latinas: The Roles Of Intimate Partner Violence, Posttraumatic Stress Disorder, And Marianismo Beliefs, Jessica Flores

Theses and Dissertations--Psychology

Intimate partner violence (IPV) has been linked to poorer condom use outcomes and sexual functioning in women broadly. Limited studies have examined these associations in Latina samples through a culturally sensitive, trauma-informed lens. A sample of 383 U.S. Latina/Latinx/Hispanic women (Mage = 25.29 years; SD = 4.44) who had a past-year intimate relationship completed a cross-sectional online survey of IPV history, posttraumatic stress disorder (PTSD) symptoms, marianismo beliefs (i.e., traditional Latina gender role expectations), condom use outcomes (i.e., condom use attitudes, efficacy, negotiation efficacy, and behaviors) and sexual functioning. Linear regression models found that past-year IPV was positively related …

Body-Based Harassment And Eating Disorder Symptomology In Cisgender, Transgender, And Gender Nonconforming Individuals, Sharla D. Biefield

Theses and Dissertations--Psychology

Past research estimates that over 60% of adolescents and young adults report eating disorder symptomology (EDS), increasing their risk for psychiatric and physical comorbidities, substance abuse, and self-harm. EDS rates are also higher among transgender and gender nonconforming (TGNC) individuals. TGNC individuals also experience higher rates of bias-based harassment, than their cisgender peers. Much of this harassment is body-based harassment (BBH), such that the harassment often targets aspects of an individual’s body. The current study utilized a pantheoretical framework, incorporating minority stress theory and objectification theory, and a multi-method approach to investigate (1) if BBH increases TGNC individuals’ risk for …

Social Transformation During The Middle - Late Preclassic (1,000 Bce - 150 Bce) At Ucí, Yucatan Mexico, Daniel Vallejo-Cáliz

Theses and Dissertations--Anthropology

The focus of this project is to track the social change developments in Ucí, Yucatan, Mexico, during the Middle (1,000 – 400 BCE) and Late Preclassic (400 – 150 BCE) that served as foundations to institutionalized hierarchy. This research is geared towards understanding if there were any expressions of social differentiation in the earliest, detectable moments in the history of Ucí, and what were the mechanisms used to eventually make distinctions permanent. Applying an agency approach, I argue that social actors may cause structural change, both consciously and inadvertently, through the application of several strategies aimed to enhancing their role …

Nursing Faculty Publications

Background: Family caregivers are at a high risk for low quality of life due to caregiving-related stress. Caregivers' stress is commonly assessed using self-reported measures, which reflect relatively subjective and long-term stress related to caregiving, but objective biological markers of stress are rarely used for caregivers. The purposes of this study were (1) to determine whether caregiver characteristics were associated with stress assessed using a stress biomarker (serum cortisol) and a self-reported caregiving distress measure (Caregiver Burden Inventory) and (2) to determine the predictability of both stress measures for quality of life in caregivers of patients with heart failure. Methods: …

Broken Down: A Mixed Methods Inquiry Examining The Mechanics Of The Segmenting Principle Using Flipped Math Instruction For Automotive Technicians, John David Baumgarten

Theses and Dissertations--Curriculum and Instruction

Mayer’s Segmenting Principle requires an instructional designer to both break the instruction into small functional pieces and pause instruction between each of these pieces until a student signals readiness to move on. Over decades of research, investigators have consistently demonstrated that segmented multimedia content achieves better learning assessment outcomes than continuous content across various academic disciplines, ages, and ability levels. While current segmenting research has shown impressive results in tightly controlled experimental scenarios, there is far less research on its application in the real world. To date, the vast majority of segmenting principle studies only assess short-term knowledge using an …

Principals As Instructional Leaders: Building Knowledge Of Applied Learning To Confidently Lead Implementation, Janell Lynn Mcclure

Theses and Dissertations--Educational Leadership Studies

Principals need to understand best practices and research-based strategies that foster student success and that align to their instructional expectations and professional goals. Some of those practices include applied learning strategies such as integrated learning, student-driven learning, and authentic applications. Unfortunately, little professional learning, specifically for principals, is made available on the topic of instructional leadership, current strategies, or applied learning in general. As a result, school leaders continue to follow a traditional instructional model that includes teacher-directed instruction, student recall of information, and standardized tests as measures of content mastery.

This dissertation was a mixed-methods action research study. The …

Development And Validation Of An Instrument To Measure Teacher Self-Efficacy For Meeting The Needs Of Military-Connected Children, Amy M. O'Neill

Theses and Dissertations--Education Sciences

The average military child changes schools six to nine times before graduating high school. With those moves come significant educational challenges, but there is currently no known instrument designed to measure whether teachers believe they are capable of meeting the needs of this population. The purpose of this study was to develop, pilot, and provide initial psychometric evidence for a scale, the Teacher Self-Efficacy Scale for Military Kids (TSES for MilKids), that measures teacher self-efficacy for meeting the needs of military-connected children. A 19-item instrument was created and distributed to regular education teachers in Grades 1-5 in civilian school districts …

The Protection Of Student Data Privacy In Wisconsin School Board Policies, Curtis Clyde Rees

Theses and Dissertations--Education Sciences

American schools have increasingly adopted technology resources to fulfill their educational obligations. These tools are for instruction, communication, and storing and analyzing student information. Student data can be directory information, enrollment records, achievement data, and student-created products. This increased utilization began with the passage of No Child Left Behind in 2001, and the COVID-19 pandemic led to more educational technology use of student data. Districts turned to third-party vendors for assistance with data systems and virtual learning resources. Before, during, and after the pandemic, stakeholders were concerned about information security and the students' privacy. School leaders looked to federal regulations …

The Perceptions And Usage Of The Interactive Video Playposit In A General Chemistry Course, Tracy Gastineau-Stevens

Theses and Dissertations--Education Sciences

Technology within science, technology, engineering, and mathematics (STEM) classrooms has been a topic of discussion for decades (Reiser, 2001, 2007). With the inclusion of more technologies or digital tools in the classroom has pushed classes towards a blended learning or flipped classroom approach (Atkins 2015; Tayebinik & Puteh, 2013; Williams et al., 2008). One such digital tool that has started gaining traction in the STEM classroom is the interactive video (M. K. Seery, 2013; Smith, 2013). Interactive videos allow students to watch the general lecture material outside of class and work through problems during normal class time (M. K. Seery, …
