Soft Prompt Tuning For Augmenting Dense Retrieval With Large Language Models, Zhiyuan Peng, Xuyang Wu, Qifan Wang, Yi Fang

Computer Science and Engineering

Dense retrieval (DR) converts queries and documents into dense embeddings and measures the similarity between queries and documents in vector space. One of the major challenges in DR is the lack of domain-specific training data. While DR models can learn from large-scale public datasets like MS MARCO through transfer learning, evidence shows that not all DR models and domains can benefit from transfer learning. Recently, researchers have resorted to large language models (LLMs) to improve the zero-shot and few-shot DR models. However, the hard prompts or human-written prompts utilized in these works are suboptimal and the generated weak …

Fire District Impacts On Coastal Access In Rhode Island, Annie Longo

Open Access Master's Theses

There are forty-two fire districts in the coastal state of Rhode Island, nine of which are now archaically named, as they no longer provide firefighting services nor have any firefighting responsibilities. Weekapaug, Watch Hill, and Bonnet Shores fire districts are three coastal fire districts that are uninvolved with fire suppression generally, aside from the occasional bonfire permit or fireworks show. Fire districts are quasi-public entities with taxing authorities and land ownership capabilities that act as the “keepers” of many miles of pristine coastline, instead of strictly as fire departments. The actions of these fire districts often conflict with coastal access …

Development Of An Autonomous Lab-On-Paper Device For Enzymatic Activity Assays- Proof Of Concept, Cameron Hahn

Open Access Master's Theses

This work aims to build on URI’s autonomous Lab on Paper (LoP) platform technology, which was used to conduct enzyme-linked immunosorbent assays (ELISAs), to conducting enzymatic activity assays. This requires new optimizations and designs to accommodate the test. In this work we use alkaline phosphatase (ALP) enzyme as the model analyte for the proof-of-concept. To accompany the new device, new MATLAB analytical tools were written and tested, to aid in robust colorimetric signal analysis. The test fixture was designed to be reusable, when a new paper circuit and reagent vials are supplied, however, it was assumed that an eventual final …

The Influence Of Gender On Perceptions Of Warmth And Competence In Leaders, Atticus Carroll

Open Access Master's Theses

Humans rely on stereotyping to simplify and process a complex world. The Stereotype Content Model (SCM) identifies two main dimensions of stereotyping known as warmth and competence. Previous literature has focused on perceptions of cisgender men and cisgender women, referring to those whose gender identity aligns with their sex assigned at birth, along these dimensions. However, nonbinary individuals reject the traditional gender binary, and it is not known how warmth and competence perceptions will be applied to this demographic. This study investigated whether a nonbinary leader would be rated lower on warmth, competence, and desire to have as a boss …

A Systematic Review Of The Role Of Emotion Regulation In Predicting Behavioral Inhibition Symptoms Among School-Aged Youth, Anne C. Nields

Open Access Master's Theses

Mental health challenges represent a key construct to focus on in support of childhood and adolescent well-being. Mental health challenges represent the leading cause of disability among children and adolescents. Recent research on critical periods in brain development shows that early childhood and adolescence mark times in which behavioral, neurodevelopmental, and mental health features arise. Anxiety disorders, which involve the excessive presence of fear and anxiety, are among the most common psychiatric disorders affecting youth and adults today. Emotion regulation (ER) and behavioral inhibition are important constructs correlated to anxiety which may be leveraged to predict and intervene on the …

Predicting Evapotranspiration, Quick Flow, And Recharge In The Contiguous United States Through 2100, Paige Aldenberg

Open Access Master's Theses

Groundwater pumping has more than doubled since 1950 across the United States and now accounts for more than 50% of water use in much of the country. These high pumping rates have exceeded recharge in many aquifers, especially in the dry Western United States. As a result, water levels are declining, increasing water scarcity for humans, and causing various adverse ecosystem impacts. So, predictions of future groundwater recharge rates, especially in the face of changing climates, are necessary for informing future water management practices. While historical groundwater recharge rates have been estimated across broad geographic regions, high-resolution predictions of future …

Association Between Vitamin D Status And Cortisol Concentration Among Pregnant Women, Kenneth Addae

However, limited research has explored the association between vitamin D status and cortisol concentration during pregnancy. Our objective for this study was to determine the association between vitamin D status and cortisol concentration among pregnant women.

Methods: The Prenatal Health and Nutrition (PHAN) study was a pilot cross-sectional study of 30 healthy pregnant women conducted in targeted areas in Rhode Island. Data was collected on sociodemographic characteristics, substance use, perceived stress scale, household food security, …

Adam Smith And The Division Of Labor, Maria Pia Paganelli

Economics Faculty Research

For Adam Smith, people need to be free to receive the fruits of their labor both because it is their right and also because it will give incentives to produce more and innovate more. Increased production and innovation will generate the prosperity that brings people out of absolute poverty. They create the means to support a growing population, and a cheerful society.

The Role Of Socioeconomic Indicators On Child Behavior And Academic Outcomes During Elementary School, Ashlee Mineau

Open Access Master's Theses

The impact of a child's socioeconomic status (SES) impacts all aspects of development. Children’s SES will be examined to determine the potential impact they may have on children's academics and behavior. The SES variables that will be examined are parent education, parent occupation, and household income. Parent education is one of the strongest predictors of child school achievement (Martinez et al., 2022). Children who come from a lower SES household are more likely to display externalizing behaviors (Barry et al., 2022). This study in particular looks at its impact for academic achievement in reading, math, and science and external problem …

Impact Of Adverse Childhood Experiences And Hostile Attribution On Adult Romantic Relationship Dynamics, Richeila Lora

Open Access Master's Theses

The purpose of this study was to examine whether experiencing ACEs and hostile attributions led to engaging in conflict behaviors in adult romantic relationships. Additionally, it was examined whether hostile attributions served as a moderator in the relationship between experiencing ACEs and engaging in conflict behaviors. Participants were adults (N = 3.684) from the German Family Panel dataset. Structural equation modeling was used to examine the associations between experiencing ACEs, hostile attributions, and conflict behaviors. It was found that both experiencing ACEs and hostile attributions were related to engaging in conflict behaviors. However, hostile attributions did not serve as …

The Effects Of Shoe Forefoot Design On Center Of Pressure And Knee Moments During Running In A Fatigued And Non-Fatigued State, Tyler Tran

Open Access Master's Theses

Runners experience high injury prevalence, which can be attributed to the overloading of the musculoskeletal system during the repetitive motion of running (Kakouris et al. 2021, Lopes et al. 2012). While some running mechanics are associated with better performance or increased risk for developing an orthopedic condition, many are still poorly understood (Van Hooren et al. 2024, Willwacher et al. 2022). Center of pressure and frontal plane knee moments are two such mechanics with a limited body of evidence leading to its importance (Mehdizadeh et al 2021, Baker et al. 2018). Although running mechanics describe the motion, the origin of …

Diet Quality And Quality Of Life Among People With Parkinson’S Disease, Elizabeth Tierney

Open Access Master's Theses

Poor diet quality (DQ) and reduced quality of life (QoL) are concerns for people with Parkinson’s disease (PwPD). Non-motor (NMS) and motor symptoms (MS) significantly impact the DQ and QoL of PwPD which can be alleviated through diet intervention. This study examined the relationship between DQ and QoL in PwPD and investigated participant perspectives to identify themes related to nutrition care. This was a secondary data analysis of EMPOWER PD. Diet intake was assessed via the Dietary Screening Tool (DST). Quality of life was assessed by the Parkinson’s Disease Questionnaire-39-item (PDQ-39). Participant perspectives were collected through 1:1 interviews. Nineteen participants …

Herbivore Kairomones Affect Germination Speed, Seedling Growth, And Herbivory, Brooke Pellegrini

Open Access Master's Theses

Seeds and seedlings are particularly vulnerable to herbivory. Unlike mature plants, which can wait until herbivory is experienced to induce defense, seeds and seedlings face mortality if they wait. Slug mucus functions as a kairomone, a non-attack-related substance emitted by consumers that is detected by a prey species (in this case, plants). While snail mucus has been shown to induce defense in seedlings, it is not widely confirmed whether slugs have the same effect and whether seeds can also detect and react to such herbivore cues. We investigated how exposure to Arion subfuscus mucus affected growth and defense in Brassica …

Financial Factors And Relationship Satisfaction: A Systematic Review Using The Tccm Framework, David Gardner

Open Access Master's Theses

Relationship satisfaction is critically important for the overall health of the relationship and is therefore inherently desirable for anyone who wants to maintain a long-term romantic relationship. Financial factors have been associated with relationship satisfaction in past research, demonstrating a need for systematic exploration. The purpose of the study is to systematically explore how financial behaviors, values, and macroeconomic systems are connected to relationship satisfaction. The current systematic review follows the PRISMA framework for exclusion and identifies 30 articles studying financial factors and relationship satisfaction from Scopus, PsychInfo, and Web of Science. The analysis followed the Theory, Context, Characteristic, and …

Using A Self-Report Survey To Determine Students’ Self-Concept, Math Attitudes, And Achievement In Ability-Grouped Math Classrooms, Jessica T. Blake

Theses and Dissertations--Educational, School, and Counseling Psychology

Ability grouping is a common practice in the United States that aims to acknowledge differences in student ability by dividing students into more homogeneous groups. Numerous studies have examined factors associated with ability grouping such as self-concept, math achievement, and attitudes toward math, but there is little empirical research exploring these three factors simultaneously. The current study examines the differences in achievement level, achievement gains, math self-concept, and attitudes toward math in middle school students enrolled in math classes based on student ability. Participants included 407 middle school students across two schools that use between-class ability grouping for math. Students …

A Scoring Approach For Evaluating And Ranking Complete Streets Projects, Eirini Stavropoulou

Theses and Dissertations--Civil Engineering

Complete Streets is a vital strategy for developing an equitable transportation network that provides access to all users and transportation options to communities. A growing interest in this concept has been noted in the United States, with over 1,700 Complete Streets-related policies implemented nationwide. The Kentucky Transportation Cabinet (KYTC) has developed the “Complete Streets, Roads, and Highways Manual” and the “Complete Streets Policy” aiming to promote a safer and more inclusive transportation system statewide through Complete Streets implementation. A recent KYTC initiative was the development of a scorecard to systematically evaluate Complete Streets projects competing for funding. The scorecard is …

Advancing Vapor Intrusion Science Using Systematic Frameworks To Foster Informed Decision Making, Hong Cheng Tay

Theses and Dissertations--Civil Engineering

Vapor intrusion, the migration of subsurface vapors into indoor air spaces, is an important source of indoor air contamination to consider at hazardous waste sites contaminated by volatile organic compounds (VOCs). There is considerable uncertainty and variability in the factors that influence vapor intrusion processes, which poses a significant challenge for decision making, despite advancements in vapor intrusion science. This dissertation consolidates knowledge from existing scientific advances and investigates scientific gaps associated with the vapor intrusion preferential pathway conceptual model (i.e. conduit vapor intrusion), associated with the vapor entry pathway into buildings via sewer systems. The overall goal of this …

The Disappearance Of Shannon White, Kathryn J. Limberg

Theses and Dissertations--English

The Disappearance of Shannon White is a Mystery-Thriller novel. The aim of the piece is to explore thematic components including perseverance, socio-economic inequities, the stigmas and medical malpractice of the American mental health system in the late twentieth century, and, ultimately, to entertain. My earliest love in the literary world was science fiction and fantasy. Writers like Robert Jordan, and more recently, Simone St. James, create worlds that test the bounds of reality in a way that I find liberating, and I seek to implement this in my own work. Such authors have taught me that fiction offers freedom to …

Feeling And Experience In American Women's Writing From The First World War, Anika Jensen

Theses and Dissertations--English

This dissertation analyzes the political capacity of feeling in American women’s autobiographical and semi-autobiographical writing from and about their work during the First World War. Women produced emotionally complex accounts that resist easy categorization, and I argue that attending to feeling clarifies not only their emotional experiences with war work but their social and political projects. This dissertation closely examines portrayals and rhetorics of feeling, considering the intersections of gender, class, race, and labor in impacting how feelings are depicted, negotiated, and conveyed. While British women were more compelled to perform and convey feeling according to a rigid class system, …

"These Are The Concepts Of The Father": Proclus' Solution To Parmenides' Dilemma, Daniel J. Grifferty

Theses and Dissertations--Modern and Classical Languages, Literature and Cultures

This master’s thesis will attempt to solve a dilemma presented by Parmenides in Plato’s dialogue of the same name. This dilemma arises because the young Socrates suggests that the forms may be thoughts that come to be in the soul. Parmenides responds to this statement by attempting to force Socrates to admit that this can only lead to one of two outcomes: (1) each thing thinks because it is composed of thoughts or (2) each thing does not think, even though it is composed of thoughts. Both of these outcomes are unsatisfactory and do not provide a solid grounding for …

Applications Of Remote Sensing Data To Understanding Geohazards In Wyoming And Kentucky, Meredith Swallom

Theses and Dissertations--Earth and Environmental Sciences

Shallow geohazards such as earthquakes, landslides, and floods profoundly impact communities globally. Constraining susceptibility to these hazards is critical for effective hazard mitigation and building more resilient communities. This dissertation includes multiple studies that leverage remotely sensed datasets to address hazard susceptibility, including: (1) characterizing a potential northern extension of the Teton fault system, (2) deriving a vegetation-based metric to improve landslide susceptibility maps in eastern Kentucky, with potential global implications, and (3) combining numerical modeling, landscape models, and field constraints to understand how anthropogenic factors affect flood severity in southern Appalachian catchments.

In the first study, analysis of new …

Plastic Gerontologies: Epigenetic Clocks As Instruments Of The Profitable Medicalization Of Aging, Hans T. Purisch

Theses and Dissertations--Geography

Epigenetic clocks are algorithms that use epigenetic biomarkers of aging to calculate an organism’s ‘biological age.’ Through discursive analysis of commercially available epigenetic clock marketing materials, scientific articles, and interviews with actors in the longevity biotechnology industry, this study examines the commercialization of epigenetic clocks in the form of consumer test-kits. The study argues that longevity biotechnology companies leverage the malleable and fluid qualities of epigenetic markers of biological age to extend the domains of profitable therapies. It shows that epigenetic clock companies market the dynamic qualities of epigenetic biological age measurements to redefine health around the project of optimizing …

Woke-Lahoma: Anti-Trans Ideology On The Frontlines, Sarah H. Fogel

Theses and Dissertations--Geography

The past decade (2015-2025) of American politics has been marked by a sharp rise in anti-trans politics. Indeed, during this period, anti-trans rhetoric and legislation have become central to American conservative politics more broadly. As the Republican party under Donald Trump works daily to remake the federal government in its image, studying the recent past of Republican-controlled states like Oklahoma offers a window into the future of anti-trans politics at the national scale. This thesis uses a mix of discourse analysis of anti-trans media and participant observation at 2SLGBTQ+ Pride events to analyze the ideological underpinnings of the present-day anti-trans …

Making Slums Legible, Visible And Calculable: Geospatial Technologies And The Governance Of Urban Land In Mumbai, Sanjana Krishnan

Theses and Dissertations--Geography

This dissertation examines how geospatial technologies are used to make slums in Mumbai legible, calculable, and hypervisible, and how these practices reshape urban land governance. It situates mapping, remote sensing, and algorithmic systems within their political-economic contexts, showing how technologies intending to see the city often function as instruments of dispossession. The research has three interconnected empirical chapters. The first empirical chapter traces the history of slum mapping in Mumbai, from their absences in early development plans to their selective hypervisibility under the contemporary governance regimes. Using critical cartographic methods, it highlights how novel technologies such as remote sensing, biometric …

Analyzing Agency In Online News Reporting Of The Events Of January 6th, 2021: A Corpus-Based Investigation, Matthew W. Abernethy

Theses and Dissertations--Linguistics

Over the last decade or so, politics in the United States has become increasingly polarized. A central focus of this polarization has been the news media, including both traditional print news, online news, and television news. Results of this have been a rapid rise in misinformation, disinformation, the demonization of news (especially political) providers as purveyors of ‘Fake News’, and distrust in mainstream news outlets. The central focus of this thesis is bias in news reporting, leading naturally to the question of how widespread this bias really is. This thesis uses corpus linguistic and discourse analytic methods to pursue this …

Cognate Facilitation And Processing In English-Speaking Learners Of German, Kaitlin L. Young

Theses and Dissertations--Linguistics

Within the field of second language acquisition, research finds that increased exposure to input results in improved proficiency, especially when those activities are challenging yet manageable for the language learner’s current level. Because of this, listening exercises and speech processing are considered integral to language acquisition, even leading to recommendations of frequent, authentic use of the target language (TL). Instructors’ TL authenticity is, however, sometimes stunted by the demand for comprehensible input and facilitation of classroom activities; they make use of simpler syntax, stronger enunciation, and more cognates (words sharing origins, meanings, and form across languages) than in casual speech. …

Orthographic Errors For Dysgraphic Second Language Learners In Russian And Hebrew, Kyra O. Morgan

Theses and Dissertations--Linguistics

Students of Second Languages might be asked to learn new writing systems in the classroom. This study is interested in how dysgraphic students, that is, students with a specific learning impairment with regards to written expression, make errors in comparison to their peers. These errors revolve around orthography, spelling, and spacing. However, this study will take a turn and focus on how all of the respondents understood the prompt and what that says about their relationship with writing in the classroom.

Shaping A City: Municipal Housekeeping, Civic Activism, And Urban Environmentalism In Progressive Era Louisville Through The Women’S City Club, Amy J. Malventano

Theses and Dissertations--History

At the turn of the twentieth century, rapid industrialization and urban expansion transformed American cities, creating urgent challenges in governance, public health, and environmental management. In response, women across the United States extended their domestic expertise into the public sphere, spearheading initiatives to improve sanitation, waste disposal, and urban infrastructure. This dissertation examines the Louisville Women’s City Club (LWCC) as a case study of municipal housekeeping, demonstrating how middle-class women used their traditional roles to influence systemic reform in Louisville, Kentucky. By bridging gender history, urban environmentalism, and Progressive Era activism, this study reveals how the LWCC shaped public policy …

“A True And Broad Sympathy:” Thomas Hughes, Medievalism, And Social Justice In The Nineteenth Century, Sarah E. Stapleton

Theses and Dissertations--History

Thomas Hughes, author of Tom Brown’s Schooldays (1857), used medievalism to help solve social problems of the Nineteenth Century. This contravenes the traditional view of medievalism, especially Anglo-Saxonism, since others have used it to justify the subjugation of people of lower social status, namely the poor in England, enslaved African Americans in the United States, and Indians under British rule.

While the use of medievalism is veiled in Hughes’ work, the subtext of Tom Brown’s Schooldays demonstrated Hughes’ Anglo-Saxonism. Tom Brown and the intertextual material surrounding his narrative exhibit the characteristics of Anglo-Saxonism through cultural primitivism, the concept of allodial, …
