Characterizing The Effect Of Plasticity Index On Monotonic And Cyclic Shear Behavior Of Natural Low-Plastic Silt Mixtures, Amir Barati-Nia

Dissertations and Theses

Low-plasticity silts are "transitional" soils prevalent in many seismically active regions, including the Pacific Northwest. Most research in the literature has historically focused on sand materials or clay materials, while low plastic silt does not fit either traditional "sand-like" or "clay-like" frameworks, resulting in a knowledge gap regarding this type of soil. Knowing the behavior of this type of soil is more important because it is susceptible to liquefaction or cyclic softening. Existing research on low-plastic silts is mostly based on either intact soil, where some parameters, such as the overconsolidation ratio (OCR) and plasticity index (PI), cannot be accurately …

Ureilite Meteorite Petrofabrics: Evolution And Formation Deformational Conditions, Benjamin Botwe Agyemang

Dissertations and Theses

This thesis examines the origin and development of crystallographic fabrics in ureilites, which are primitive achondritic meteorites interpreted as residues of partial melting from a differentiated parent body. In this study, we evaluate three fabric-forming mechanisms: gravitational cumulate crystallization, shock-induced deformation, and flow alignment associated with melt extraction and convective stirring. A quantitative Electron Backscatter Diffraction (EBSD) analysis was conducted on six ureilitic meteorites to assess olivine Lattice Preferred Orientation (LPO), Shape Preferred Orientation (SPO), the connection between SPO and LPO, and other deformation metrics, including Grain Orientation Spread (GOS), and Crystal Rotation Axis (CRA). Our results suggest that most …

Opera Houses In Aberdeen, Huron, And Watertown, Sd: 1880-1910s, Janet M. Meyer

Dissertations and Theses

In the 1880s, many newcomers arrived in Dakota Territory for a new start in Aberdeen, Huron, and Watertown. Their arrival coincided with the popularity of opera houses, so it was not surprising that entrepreneurs built opera houses in these new towns. The early opera houses included several benefits. They provided important gathering places for growing communities to hold meetings and social functions. The settler-colonial society included people from foreign countries and eastern states. Opera houses were also beneficial by providing familiar shows and concerts, perhaps some shows the residents previously enjoyed in their homes back east. Knowing that an entertainment …

A Poor Man's Cup: Chicory Experimentation In Nebraska,1890-1900, Rebecca Hupp

Dissertations and Theses

“A Poor Man’s Cup” explores how Nebraskans actively confronted the problems of the late nineteenth-century through experimenting with new commodities. Prolonged severe drought, economic depression, and poor grain prices created a troublesome situation that grew in complexity as U.S. markets expanded globally and agriculture underwent professionalization. Some lay farmers, like Gabriel and Philomena Bazelman of Holt County, did not wait for new methods to find their way through the experiment station system and instead conducted trials themselves. Through piecing together the story of Nebraska chicory production with periodicals from the 1890s, experiment station bulletins, and Congressional reports, this thesis demonstrates …

Exploring The Role Of Pleasure In Cognitive Tasks, Nafisa Kazi Iqbal

Dissertations and Theses

The present study investigates whether the experience of a pleasant-valenced physical stimulus will positively influence performance on a cognitive task. The concept of hedonics is explored as hedonic responses, emotional reactions to stimuli involving feelings of pleasure and displeasure, play a crucial role in various psychological processes. There is a limited amount of literature regarding pleasant smell and its impact on the performance of cognitive tasks. The reported study addresses this limitation by comparing Stroop task performance of participants in two conditions, pleasant scent and neutral scent. These findings add to our understanding of the impact of pleasant smell on …

Large Language Model Communication And Data Transfer Across A Simulated Telephone Line, Jared Reyes

Dissertations and Theses

This thesis presents a proof-of-concept communication system in which two local large language model endpoints communicate across a simulated analog telephone line using legacy USB modems. The project combines modem voice mode, modem data mode, local speech processing, and structured machine messaging into a single staged session. During the voice phase, one endpoint places a call, the other answers, speech generated by a locally hosted LLaMA-family model is synthesized with Piper, transmitted through the modem voice path, captured on the remote side, and transcribed with Faster-Whisper to drive the next response. After the voice exchange, the system transitions to a …

All She Ever Wanted Was The World: The Emergence Of Vocal Methodology, Pedagogy, And Opera Performance For Women In The Nineteenth Century, Emma Hawkinson

Dissertations and Theses

Important music methods books began to emerge in the 1750s with instrumental treatises for flute, piano, and violin. By the end of the nineteenth century, there was a multitude of treatises for a variety of instruments, including classical voice. This study investigates and analyzes the content of treatises from four individual women who performed, taught, and published vocal treatises in the nineteenth century: German Mathilde Marchesi (1821–1913), Italian Virginia Boccabadati (1828–1922), Spanish Matilde Esteban (1841–1915), and English American Clara Kathleen Rogers (1844–1931). These methods books are set in the historical context of the music industry before and during the nineteenth …

A Mixed Methods Study On Mexican American Satisfaction And Perception Of Clinical Trials, Grace Manzo

Dissertations and Theses

In the United States, the Food and Drug Administration sets expectations on the collection and reporting of race and ethnicity data. Ethnic data for Mexican Americans is often reported as “Hispanic or Latino.” Mexican Americans make up a significant percentage of “Hispanic or Latinos,” however, they remain significantly underrepresented in clinical trials. Grounded in Expectation-Disconfirmation Theory (EDT) and Social Cognitive Theory (SCT), this mixed-methods study investigates the relationship between satisfaction and perception of Mexican Americans who have participated in an ophthalmology clinical trial. This research aimed to understand the relationships among satisfaction with the clinical trial process, patient-reported outcomes, and …

Effects Of Hurricane Weather Events On Perceived Stress, Academic Motivation, And Resilience In College Students From Louisiana, Courtney Renee Harrington

Dissertations and Theses

In the fall semester of 2020, five hurricanes were projected to make landfall along the coast of Louisiana. The following fall semester of 2021, Hurricane Ida, a major category 4 storm landed and wreaked havoc among Louisiana’s coastal universities. The purpose of this study was to assess the effects of hurricane events on students’ perceived stress, academic performance, and resilience. It was hypothesized that students affected by the landfall of a hurricane would have increased stress, decreased academic motivation, and decreased resilience compared to normative college students. A cross-sectional survey was administered at two southern Louisiana universities as well as …

Interactional Synchrony In Mother-Infant Dyads: Developmental Changes And The Impact Of Maternal Emotion Dysregulation Over Time, Jessica Taylor Kelly

Dissertations and Theses

Infancy is a period of rapid development, while motherhood is often a time of heightened emotionality (Bjelica et al., 2018; Leclère et al., 2014). Synchrony between mother and infant is one of the earliest bonding experiences, with short- and long-term implications for the infant’s development and the mother-infant relationship (Leclère et al., 2014). However, little research has characterized developmental shifts in mother-infant synchrony. Maternal emotion dysregulation is likely to influence mother-infant synchrony (Doba et al., 2022; Lotzin et al., 2015, 2016). Yet little research has evaluated the impact of maternal emotion dysregulation on mother-infant synchrony over time. This project aims …

The Efficaciousness Of Generative Ai For Integrated Stem Planning And Its Impact On Stem Teacher Self-Efficacy, Julie Ann Olson

Dissertations and Theses

With evolving workforce needs, global challenges, and national science education initiatives calling for STEM instruction with purposeful connections between the four domains, there is a need for methods to support educators facing the challenges this pedagogical approach presents. Challenges may weaken teachers' self-efficacy, potentially reducing the probability that an integrated STEM (I-STEM) pedagogy would be sustained in the classroom. There is limited research addressing how generative artificial intelligence (GAI) has been used for I-STEM lesson development, combined with its effects on I-STEM teaching self-efficacy (SE) grounded in social cognitive theory. This study investigated how GAI influences I-STEM teaching SE, when …

“A Loving and Faithful Wife” provides a procedural and gender-based analysis of twenty-five Dakota Territory divorce cases, from Clay County, ranging from 1867-1884. This analysis is based on an understanding of the procedural aspects of the territorial divorce court system, as well as nineteenth century gender ideologies, include the ideals of True Womanhood, and Separate Spheres. By employing a close reading method, this research analyzes the language in court filings, allegations used in complaints, and the outcome of the cases. This analysis reveals men and women used unspoken gender scripts to present their marriages to the court and attempt to …

"Cap No Belong To Busha:" Property-In-Labor And Apprenticeship In Jamaica, 1834-1838, Ashley S. Getting

Dissertations and Theses

The four-year period of apprenticeship in Jamaica was a critical period in the transition of labor relations between enslaver/enslaved and master/apprentice. This study examines the Abolition of Slavery Act of 1833 and colonial office records to consider the ways masters and apprentices interpreted property-in-labor and how they employed those interpretations to begin negotiation what a 'free labor' sugar economy might look like post-apprenticeship. Using the lens of freedom practices to examine colonial dispatches and court records, I construct the apprentice understanding of their new labor relation. Apprenticeship meant a new legal status where individuals were no longer chattel, and the …

Painted By Hand, Written In The Sky: Martin Wong’S Fingerspelling As Invented Visual Language, 1982-1985, Bella Clemente

Dissertations and Theses

This thesis examines Martin Wong's (1946-1999) hand-painted fingerspelling as an invented personal visual language and vehicle of self-portraiture, analyzing three paintings created during his time in New York between 1982 and 1985: Attorney Street: Handball Court with Autobiographical Poem by Piñero (1982-1984), Compulsion (1984-1985), and Stanton Near Forsyth Street (1983). Through iconographic analysis of lingual elements in each work, including fingerspelling, graffiti, calligraphy, and poetry, this thesis argues that Wong's stylized adaptation of the American Sign Language manual alphabet reflects an evolving sense of self-identity, drawing on influences from Chinese artistic traditions, calligraphy, Kufic script, and the Nuyorican poetry and …

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.

Identifying Barriers To High School Graduation Based On Experiences Of Former Students With Limited Or Interrupted Formal Education (Slife): A Case Study, Marcia Gaudet

Dissertations and Theses

Multilingual students with limited or interrupted formal education (SLIFE) were underrepresented in the professional literature. Accordingly, the purpose of this research brief was to contribute to an emerging line of research by documenting the voices of SLIFE with regard to barriers to high school graduation they experienced during their educational experiences alongside what supports they experienced that helped remove such barriers. Data was collected through interviews and focus groups, where participants provided first hand accounts of their high school experiences. The researcher’s results showed the importance of personal relationships with teachers, administrators, and mentors from the community. The researcher’s findings …

Teaching Kitchen Safety Using A Modified Coach In The Kitchen Curriculum Paired With Behavioral Skills Training Procedure With Young Adults With High Functioning Autism, Ryan Michael Groeneweg

Dissertations and Theses

Few intervention studies address the needs of young adults with high‑functioning autism spectrum disorder (ASD) as they transition toward adulthood. This study used a single‑subject multiple‑baseline design across participants and skills to evaluate the effects of a modified Coach in the Kitchen curriculum paired with Behavioral Skills Training (BST) on the acquisition of kitchen safety behaviors. Three adults with high‑functioning autism were taught task‑analyzed steps for safe use of a kitchen peeler, knife, and hot liquids. Instruction incorporated modeling, rehearsal, feedback, prompting, and strategies for generalization and maintenance. Performance was measured as the percentage of safety steps correctly completed during …

Creating A Modern American Piano: Antecedent, Launch, And Reinvention Of Mason & Hamlin's Piano Line Through 1905, Arian Sheets

Dissertations and Theses

The American piano industry was in a significant period of technical innovation, increased production, and standardization during the second half of the nineteenth century. This resulted in the American form of the instrument dominating the design and sound ideals still expected of the modern piano. Mason & Hamlin, a major reed organ company, entered the piano market in the early 1880s, relatively late compared to the largest, and most market-dominant companies, such as Steinway and Chickering. This thesis examines the origin and early implementation of the designs and innovations that have become standard for the modern American piano, and how …

Development Of An Adhesive Emulsion Hydrogel For Soft Tissue Reconstruction, David J. Alpert

Dissertations and Theses

Soft tissue filling materials are most commonly associated with various aesthetic, cosmetic procedures, primarily using lightly cross-linked hyaluronic acid to fill wrinkles and give facial features a more youthful appearance. These natural materials are biocompatible but degrade over time while more persistent synthetic fillers may provoke a chronic inflammatory response. Migration from the injection site is also a key factor as this may not only render the implant non- functional but necessitate further procedures for removal of the foreign material. Such concerns are more pronounced for soft tissue reconstruction procedures (e.g., to treat congenital defects or traumatic injuries), which require …

Design, Testing And Controls For Air Source Heat Pump System In Cold Climates Using Natural & Conventional Refrigerants, S M Abdur Rob

Dissertations and Theses

Fossil-fuel based heating systems used in the residential buildings in northeastern U.S region are not only inefficient but also largely responsible for the greenhouse gas emissions in U.S. Electrification of the buildings has been proved to be the most efficient way to reduce the greenhouse gas emissions where Heat Pumps can be the best alternative to replace the natural gas based heating system to accelerate the electrification process. Among different types of heat pumps, the Air Source Heat Pump (ASHP) system is widely used due to the easy installation and energy efficiency. Conventional heat pump technologies use various types of …

Hybridization And Introgression In Marine Invertebrates: Population Genomics Of Phymactis Papillosa And Asterias Sea Stars, Christopher J. Dookie

Dissertations and Theses

Hybridization and introgression are evolutionary significant processes in marine invertebrates (Sanford & Kelly,2011) yet genome-wide investigations of gene flow in these taxa remain limited relative to vertebrate systems (Marchi et al., 2021). This thesis presents genomic analyses of hybridization and introgression in two marine invertebrates occupying contrasting oceanographic settings and characterized by contrasting genomic datasets: restriction-site associated DNA sequencing (RADseq) SNP data for the eastern Pacific sea anemone Phymactis papillosa and whole genome sequencing (WGS) data for the North Atlantic sea stars Asterias rubens and Asterias forbesi. For each system, I applied coalescent-based species tree inference using CASTER (Zhang …

Mad Or Uncontrollable? Reading Female Madness In Three Gothic Texts, Amy Marie Bueno

Dissertations and Theses

My thesis employs comparative close reading framed by disability studies to analyze representations of female madness in Charlotte Brontë’s Jane Eyre, Jean Rhys’ Wide Sargasso Sea, and Isabel Allende’s “If You Touched My Heart.” Drawing on theories of socially constructed disability, it argues that Bertha, Antoinette, and Hortensia are framed as “mad women” not through inherent pathology, but through patriarchal violence, colonial domination, and institutional power. By integrating the social model of disability with feminist theory, this thesis examines how women are rendered disabled within societies influenced by Social Darwinism and eugenic ideologies.

This thesis further incorporates Gothic theory and …

Financing Global Health Governance: The World Health Organization, The Who Foundation, And The Shifting Landscape Of Development Financing, Johanny O. Reyes

Dissertations and Theses

This thesis analyzes the structural financing challenges facing the World Health Organization (WHO) and their implications for global health governance. It argues that WHO’s financial fragility is not merely a technical problem but the result of long-standing political and institutional choices that have shifted the Organization away from predictable public financing toward donor-driven, earmarked voluntary contributions. Drawing on WHO constitutional provisions, programme budget data, governance documents, and academic literature, the study traces the evolution of WHO’s financing model and examines how this transformation has constrained the Organization’s priority-setting authority, operational flexibility, and normative leadership.

The COVID-19 pandemic serves as a …

Disaster Risk Management During Climate Emergencies In The Dominican Republic And Puerto Rico, Rosleny Ubinas

Dissertations and Theses

This paper analyzes the DRM approach as an effective framework in addressing climate emergencies across the Dominican Republic and Puerto Rico. These two Caribbean regions, with high hurricane exposure and differing response structures, are deeply shaped by their governments and affiliated international organizations. Disaster Risk Management is the systematic process of using laws, plans, institutions, and community networks to reduce vulnerability to hazards and coordinate effective response when disasters occur. It covers the full cycle, from prevention to reconstruction and rebuilding more resiliently. The Dominican Republic’s law-based intervention led to greater local-level community participation during disasters with its embedded volunteer …

Executive Self-Management Of Reading And Writing For College Students With Adhd, Jiajie Li

Dissertations and Theses

Background. College students with ADHD often experience difficulties with self managed academic tasks, for which there are currently few specific interventions. The present study examined associations among ADHD symptom severity, executive functioning, academic achievement, and perceived helpfulness of reading- and writing-focused sessions within a cognitive-behavioral intervention for college students with ADHD. Method. N = 41 undergraduate students (Mean age = 21.32 years, SD = 2.74; 70.7% female) with ADHD were recruited into a 12-week group-based cognitive behavioral intervention for executive functioning difficulties. Two sessions were devoted to skills and strategies specific to academic tasks, Reading for Retention and Planning, Organizing, …

The Ick Factor: Explaining The Term Through Lenses Of Sexual Disgust And Avoidant Attachment Style, Maxum O'Halloran

Dissertations and Theses

The phenomenon of the “ick” has gained significant traction in the context of modern romantic relationships, particularly across social media platforms, where individuals describe trivial negative traits and habits in potential and current romantic partners. Despite their trivial nature, icks are often treated as meaningful dealbreakers, raising questions about whether they reflect genuine psychological processes or are simply a social media trend. The present study examined whether the presence of an ick influences perceptions of attractiveness and dateability, and whether individual differences in sexual disgust sensitivity and attachment style help explain icks and reactions to icks. Participants (N = 236) …

Relational Spirituality And Maternal Coping In Carceral Contexts: A Participatory Action Study Of Meaning-Making And Mental Health Among Formerly Incarcerated Mothers, Jessica Peters

Dissertations and Theses

Maternal incarceration carries significant psychological, familial, and community consequences, yet limited research centers the mental health experiences of mothers themselves. This study explored how religious and spiritual engagement shape mental health and coping among formerly incarcerated mothers using a participatory action research framework. Guided by this, small groups and semi-structured interviews were conducted with 10 mothers in collaboration with a community-based organization. This approach prioritized lived experience and aimed to reduce barriers to participation among a population often mistrustful of research institutions. Data were analyzed thematically to identify patterns in psychological distress, coping strategies, and meaning-making. Findings revealed pervasive and …

Shared Burden, Potential Space: A Qualitative Study Of How Psychodynamic Therapists Work With Intergenerational Transmission Of Historical Trauma, Shaun J. Halper

Dissertations and Theses

The intergenerational transmission of trauma (ITT) has been investigated since the 1960s, beginning with research on the descendants of Holocaust survivors. Few qualitative studies, however, have taken up how psychodynamic therapists experience their treatments with adult patients with ITT. This study uses Interpretive Phenomenological Analysis (APA) to analyze adult ITT treatments from the perspective of psychodynamic psychotherapists. Ten licensed clinicians in the NYC tri-state area participated in semi-structured interviews, which were organized around three research aims: how clinicians conceptualized and identified ITT, what effective clinical interventions they used, and how they understood the impact of therapist-patient sameness or difference (regarding …

Examining The Spatial Variability Of Summer Heat In New York City Using Landsat Land Surface Temperature, Ryan Kabir

Dissertations and Theses

Extreme heat is the leading weather-related cause of death in the United States, and in New York City (NYC) approximately 370 heat-related deaths occur annually on average. The spatial distribution of surface heat exposure across NYC is highly uneven, low-income neighborhoods and communities of color consistently face higher temperatures, yet the intraurban spatial structure of land surface temperature (LST) during heatwave events has not been systematically characterized at high resolution. The New York City Panel on Climate Change Fourth Assessment (NPCC4) identifies this as an explicit research gap, noting that its own projections, based on global climate models downscaled to …

Civil War Memory In New York City, 1861-1902, Kevin J. Sugrue

Dissertations and Theses

This thesis examines how New York City experienced, understood, and later remembered the American Civil War, from the outbreak of war (1861) through the dedication of major monuments at the turn of the twentieth century (1902). Although New York was the Union’s largest city and its most significant source of troops, casualties, industrial output, financial capital, and press coverage, the city’s wartime experience was deeply conflicted. As a Democratic stronghold and home to large populations of recent immigrants and working-class laborers, New York’s support for the Union was broad but conditional, fractured by class, ethnicity, race, and political allegiance. These …
