Red-Sensitive Photopolymerizable Glass For Fabrication Of Holographic Optical Elements, Jamshed Aftab, Izabela Naydenova, Tatsiana Mikulchyk

Research Outputs: 2025-Present

Water-resistant photopolymerizable glass, which represents a photopolymerizable hybrid sol–gel (PHSG) material, has emerged as a compelling platform for holographic optical elements fabrication (HOEs), owing to its exceptional mechanical and thermal robustness with high holographic recording performance. Until now, PHSG compositions have been limited to blue/green-sensitive systems, despite significant interest in extending sensitivity into the red spectral region. Here, we report the first holographic photopolymerizable glass with sensitivity to red light, achieved through the incorporation of methylene blue (MB) as a photosensitizer and N-phenylglycine (NPG) as a co-initiator, with an optimal MB/NPG ratio of 1:150. This PHSG composition is capable of …

Ai-Supported Socratic Questioning And Instructional Scaffolding: Effects On Student Comprehension, Reshma John

All Electronic Theses and Dissertations

This literature review examines how the intentional use of artificial intelligence (AI) designed for Socratic questioning and instructional scaffolding affects students' comprehension of course content. The literature suggests that AI is most likely to support comprehension when it prompts students to explain their reasoning, respond to guided questions, reflect on their understanding, and receive support adapted to their needs. In contrast, systems that primarily provide direct answers may encourage overreliance and mask gaps in students' understanding. Overall, the educational value of AI depends less on its availability and more on how it is designed and implemented.

Teaching Primary Sources To Increase Engagement And Build Literacy, Lindsey L. Beaulieu

All Electronic Theses and Dissertations

This thesis reviews the use of primary sources in education. This literature review analyzes 30 articles regarding educators’ use of primary sources. There are four major themes within the articles: literacy with primary sources, engagement with primary sources, comprehension with primary sources, and examples of primary source units or lessons. While specific teaching topics vary, the overall consensus is that primary sources can help students’ skills with literacy, engagement, and comprehension. A main topic among the research is the educators’ understanding of scaffolding, pre-teaching, choosing primary sources, and re-using the primary sources, to be able to teach students effectively.

Meconium Metal Concentrations And Infant Temperament And Development, Fiona Fogarty

Dissertations and Theses

BACKGROUND: Prenatal exposure to metals poses significant health consequences for early childhood development. Understanding the factors influencing metal concentrations that infants are exposed to in-utero is crucial for developing targeted interventions, particularly when maternal characteristics and environmental factors, may contribute to varying levels. Meconium offers insight into in-utero exposures for the developing infant, and the effect of each individual metal may be mediated or exacerbated by another and therefore should be studied in the context of a mixture. The effect of metal mixture exposure, as measured in meconium, on milestone and temperament outcomes has yet to be determined.

An Engine, Not A Vessel: Place, Politics, And Health In The United States, Philip B. Rocco

Political Science Faculty Research and Publications

Social scientists often treat places as containers for social and economic phenomena that shape health outcomes. Yet this analytic practice conceals more than it reveals. Local governments in the United States should be understood as engines of both health promotion and stratification. As the contributions to this symposium suggest, governments not only occupy a formal place in the U.S. public health system, their decisions on everything from housing to transportation infrastructure can also have profound impacts on health outcomes. Local political economies likewise renegotiate the parameters of acceptable health interventions, public understandings of health disparities, and the status of population …

A Thymine Dimer Stalls A High-Fidelity Dna Polymerase By Providing No Template Information In The Same Manner As An Abasic Site, Amanda R. Walsh, Hye Rhee Kim, Lorena S. Beese, Eugene Y. Wu

Biology Faculty Publications

Cyclobutane pyrimidine dimers are photolesions that form when UV-B irradiation causes adjacent thymine or cytosine bases to covalently bond and can arrest DNA synthesis by replicative polymerases. To gain insight into the effects of cis-syn cyclobutane thymine dimers (T=T) on DNA replication in a model polymerase, we conducted solution and crystallographic studies of the Bacillus DNA polymerase I large fragment (BF) in complex with a T=T-containing template and an incoming dNTP. A thymine dimer lesion blocked nucleotide addition by BF in solution. The crystal structure of the BF-T=T-dATP complex indicated that the thymine dimer is too large to enter the …

Good Girl Bootcamp: Performative Femininity, Purity Culture, And Other Things Girls Are Taught, Kiersten Holland

Masters Theses

Performative femininity is a dangerous and controlling idea that subjugates women and places their inherent worth on how well they can conform to societal standards in male dominated spaces. Consequently, the reactionary messaging that surfaced as a result of these social pressures created a series of stereotypical female characterizations often depicted in the material and visual cultures of each period. By comparing contemporary literature with literature from the Victorian time period, it emphasizes the longstanding and controlling gender stereotypes pervasive throughout the past few centuries. This thesis attempts to understand and analyze the way that literature both critiques and supports …

Independence Of Spectral Contrast Effects Across Different Frequency Regions In Speech Perception, Christian E. Stilp, Matthew B. Winn

Speech Pathology and Audiology Faculty Research and Publications

Identification of speech sounds is influenced by spectral contrast effects (SCEs), the perceptual magnification of spectral differences between successive sounds. SCEs result in the categorization of a target sound being biased away from spectral properties in the preceding acoustic context. Given remarkable consistency in the magnitudes of these contrast effects within the same frequency region, it was hypothesized that they would also show stable relationships across different frequency regions. In this study, normal-hearing listeners’ phoneme categorization and contrast effects were assessed where phonetic contrasts were driven by changes in low-frequency F₁ (“big”-“beg” continuum), mid-frequency F₃ (“dot”-“got”), or high-frequency …

Ebola In The Drc: A Different Problem Compounded By Violence, David Brett-Major

Journal Articles: Epidemiology

A Public Health Emergency of International Concern (PHEIC) has been declared in the Democratic Republic of Congo (DRC) due to Ebola disease from Bundibugyo virus. Non-health-focused factors should be fundamental to how DRC and its partners respond to and recover from the current emergency. Filovirus emergencies are violent in every sense-the disease experience of patients and their caregivers, the tumult in impacted communities, sometimes the physical manifestations of frustration against healthcare services, the fits and starts of concerted response, and the milieu of conflict in which this emergency occurred. Yet, interpersonal and organized violence may contribute to frequency of health …

Perceived Adolescent Insecure Attachment With Mothers And Fathers, Helena Pipová, Martin Dolejš, Jaroslava Suchá, Alexander T. Vazsonyi

Sociology Faculty Publications

The aim of this study was to test relationships between adolescent insecure attachment (anxious and avoidant) with mothers and fathers and three outcomes: food addiction, eating disorders, and weight status, in a large multi-regional sample of Czech adolescents. Anonymous, self-reported data were collected from 3,677 adolescents (1,688 boys, 45.9% and 1,989 girls, 54.1%). Both anxious and avoidant attachment with mothers were positively associated with food addiction (p <.001) and eating-disorder risk (p <.001). Importantly, avoidant attachment with fathers uniquely and additively explained variance in both food addiction (p <.001) and eating-disorder risk (p =.003), after controlling for maternal attachment. Weight status was unrelated to attachment and was predicted by sex and parental education only. Study findings highlight the salience of insecure attachment with both mothers and fathers for food addiction and eating disorders among adolescents and identify the parental relationship as a key potential preventative strategy.

This study evaluates audience and Photovoice participants’ experiences of dissemination events presenting the results of 21 Photovoice projects that supplemented the HEALing Communities Study (HCS), a multistate community-based study of strategies to reduce opioid overdose deaths. The Photovoice projects captured the perspectives of people with lived experience of substance use disorder and front-line providers regarding their …

Regulatory History And Judicial Review, Todd Phillips, Anthony L. Moffa

Faculty Publications

The Administrative Procedure Act requires federal agencies to simply "incorporate in the rules adopted a concise general statement of their basis and purpose" after they receive comments from the public, and the Supreme Court ruled in Overton Park that courts are to adjudicate whether rules are arbitrary and capricious based on agencies' contemporaneous rationales. Judge-created doctrines incentivize agencies to rely on these "concise" statements to elucidate their rationales, and as a result, rulemaking preambles have ballooned in size as agencies seek to insulate themselves from critical courts.

This article contends that although the APA's statutory requirement is in tension with …

Understanding Resilience In Children In Out-Of-Home Care: Using Person-Centered Health Services Research, Hyeeun K. Shin

Theses and Dissertations--Health Services Research (HSR)

Adverse childhood experiences (ACEs), which refer to exposure to traumatic life events before age 18, and instability in caregiving experiences contribute to poor physical, mental, behavioral, and developmental health outcomes for both children and adults. Previous research shows that these experiences can have negative effects both in the short term and throughout a person’s life. However, children’s strengths, which are the internal and external assets that support their development, can help protect against the impact of ACEs. Effective parenting, positive social support, and self-regulation skills are essential factors that build resilience, helping individuals adapt to challenges that may affect their …

Suicide Stigma In A Cross-Cultural Context: Comparison Between Mexican And Mexican American Communities., Robin E. Gearing, Micki Washburn, Kathryne Brewer, Luis R. Torres-Hostos, Pedro Isnardo De La Cruz, Miao Yu, Natalia Giraldo-Santiago, Alberto Cabrera, Adelaido Garcia Andres

School of Social Work Faculty Publications

Suicide and suicide-related stigma are serious public health issues affecting Latine communities and often serve as a barrier to help-seeking Mexicans and Mexican Americans experiencing mental health concerns. Despite this, there are still gaps in our understanding of how suicide stigma specifically impacts Latines of Mexican heritage. While Mexicans and Mexican Americans share many familial, cultural, and religious values, their exposure to different societal norms may shape distinct perceptions of suicidal ideation and mental health. To better understand suicide-related stigma in these communities, we conducted a community-based survey with 248 Mexican Americans in Houston and 203 participants in Mexico City …
