Practical Keyword Private Information Retrieval From Key-To-Index Mappings, Meng Hao, Weiran Liu, Liqiang Peng, Cong Zhang, Pengfei Wu, Lei Zhang, Hongwei Li, Deng, Robert H.

Research Collection School Of Computing and Information Systems

This paper introduces practical schemes for keyword Private Information Retrieval (keyword PIR), enabling private queries on public databases using keywords. Unlike standard indexbased PIR, keyword PIR presents greater challenges, since the query’s position within the database is unknown and the domain of keywords is vast. Our key insight is to construct an efficient and compact key-to-index mapping, thereby reducing the keyword PIR problem to standard PIR. To achieve this, we propose three constructions incorporating several new techniques. The high-level approach involves (1) encoding the server’s key-value database into an indexable database with a key-to-index mapping and (2) invoking standard PIR …

Integrating Art Therapy And Emerging Technologies For Enhanced Neuroplasticity And Ptsd Intervention, Piper Hutson, James Hutson

Faculty Scholarship

Post-traumatic stress disorder (PTSD) remains resistant to many conventional treatments, underscoring the need for integrative approaches that harness neuroplasticity. Art therapy, with its capacity to facilitate nonverbal trauma processing and multisensory engagement, has shown distinctive advantages over verbal and pharmacological interventions. Recent innovations, including virtual reality (VR), artificial intelligence (AI), and biofeedback have amplified the therapeutic efficacy of art-based interventions by enabling adaptive, real-time modulation of emotional and physiological states. This review synthesizes current research on technologically enhanced art therapy, comparing it to established treatments such as cognitive behavioral therapy (CBT) and eye movement desensitization and reprocessing (EMDR). Findings indicate …

Exploring Promising Practices In Temporary Informal Education Programs For Visitor And Community Engagement In The United States National Park Service, Cameron L. Miller

All Theses

According to the National Association for Interpretation (NAI), interpretation is “a purposeful approach to communication that facilitates meaningful, relevant, and inclusive experiences that deepen understanding, broaden perspectives, and inspire engagement with the world around us” (NAI, 2021). Interpretation is an integral part of a visitor’s experience to informal education venues like museums, zoos, aquariums, and parks and is at the heart of experience planning within the National Park Service (NPS). However, traditional interpretation methods, such as formal interpretation programs, tend to engage a small percentage of overall park visitors, that are typically older and white. Recognizing the need for interpretation …

The Future Research Direction Of Cgiar: Lessons Learned From One Cgiar, Katie Loethen

Graduate Theses and Dissertations

Since its founding in 1971, CGIAR (formerly the Consultative Group on International Agricultural Research) has been at the forefront of agricultural innovation, credited with launching the Green Revolution and delivering 1.78 trillion USD in net present value (NPV) benefits globally, particularly in low- and middle-income countries. Despite these accomplishments, CGIAR now faces internal and external pressures that threaten its future impact. The 2019 reorganization into “One CGIAR” aimed to enhance coordination but has been criticized for adding bureaucracy and reducing scientific autonomy. Simultaneously, public funding for agricultural research is shrinking, while private sector investment often overlooks low-margin, high-need areas central …

Pricing The Unknown: An Analysis Of Expected Value Of Young Horses And Price-Determining Factors, Rupasri Sura

Graduate Theses and Dissertations

From a seller’s point of view in a market, it is crucial to plan the pricing strategies based on perceptions of buyer preferences and their willingness to purchase to ensure market success in selling and pricing. Applying this to the equine industry, this paper studies the factors determining the price of young horses (age ≤ 2 years) in digital auction platforms. Using data from Professional Horse Services, LLC (2012–2023), a Heckman’s two-step approach was employed, which involves a probit model as the first step and a hedonic price model as the second, aiming to correct for sample selection bias in …

Optimal Distributed Energy Resource Control And Scheduling In A Microgrid Framework, Timothy M. Dodge

All Graduate Theses and Dissertations, Fall 2023 to Present

As we use more renewable energy, such as solar power, and add new devices, such as electric vehicle chargers and battery storage, to our buildings, the management of electricity becomes more complex. These local energy sources and devices can form small "microgrids" that need careful coordination to work efficiently with the main power grid. The system figures out the best times to use, store or charge different devices (such as batteries and EVs) to avoid costly, high electricity demand spikes and help stabilize the main power grid, especially when asked by the utility company. A major part of this work …

The project was a coordinated effort among researchers from the University of Montana’s Institute for Tourism and Recreation Research (ITRR), the Department of Public Administration and Policy, and …

What Is The Distribution Of National Historical Parks?, Randall K. Johnson

Southern Illinois University Law Journal

In an increasingly polarized nation, which no longer can reach any consensus about what is meant by the term “common good,” it might be wise to extend additional protections to national monuments from executive branch interference. But prior to doing so, the U.S. Congress may want to undertake some additional research work. Such research could build on the existing charge of the National Park Service as well as other interested parties. By doing so, Congress gains insight into whether and how this federal legislature should make greater use of the national historical parks designations.

This article explains, at least in …

Fixing A 100-Year-Old Mistake, Michael J. Graetz

Faculty Scholarship

Posing the question of international tax cooperation versus competition reminds me of multiple-choice exams in which the right answer is “all of the above.” National interests determine which dominates at any given time. And in tax competition among nations, zero is not a lower bound.

In 1918, to encourage U.S. investments abroad, the United States enacted a credit for foreign taxes paid by U.S. companies and relinquished taxing rights to most foreign-source income. With the foreign tax credit, the United States assumed sole responsibility for reducing the double taxation of its residents and citizens. As the influential economist Edwin Seligman …

When Engagement Meets Distraction: The Effects Of Multitasking Types On Learning From Video Lectures, Zubeiru Mahama

Arts & Sciences Graduate Student Theses and Dissertations

Students often multitask with lecture-relevant (e.g., note-taking) and lecture-irrelevant (e.g., texting) secondary tasks during lectures and such behavior tends to be more common in asynchronous than synchronous settings. Two experiments investigated the combined and comparative effects of lecture-relevant and lecture-irrelevant secondary tasks on attention to and retention of a geology video lecture in a simulated asynchronous setting. Participants were randomly assigned to one of four conditions: lecture-only, lecture-relevant multitasking (i.e., taking notes during the lecture), lecture-irrelevant multitasking (i.e., completing a survey in Experiment 1 or instant messaging in Experiment 2 during the lecture), or hybrid multitasking (both note-taking and survey …

Trust Across Difference In Radical Social Movement Organizations: The Case Of The Student Nonviolent Coordinating Committee, Kerstin Miller

Master's Theses

Social movement literature does not properly address trust between activists as a foundation of social movement organizations. This thesis aims to fill that gap by examining how trust within the Student Nonviolent Coordinating Committee, a radical civil rights organization in the sixties, was built and broken over the course of the decade. I drew on first-hand accounts written by SNCC activists to find patterns in how they thought about trust building and trust breaking in their own organization. I found that trust was built primarily through sustained interaction between activists, and that trust in the organization led to activists being …

The study also describes the demographic characteristics of the learners, including gender, race, and age groups, and analyzes their performance on the Test of …

Using Interpersonal Motives To Identify Latent Profiles Of Borderline Personality Pathology: Implications For An Overcontrolled Style Of Bpd, Regina Schreiber

Graduate Theses and Dissertations

Borderline personality disorder (BPD) is conceptualized as a disorder of undercontrol (i.e., behaviorally impulsive, emotionally expressive), with affective, interpersonal, and identity instability. BPD related impairment is high, yet diagnostic accuracy remains a problem for individuals who present with greater overcontrol (i.e., behavioral inhibition, expressive suppression), which occurs in some BPD subtypes. The current study used ecological momentary assessment (EMA) to expand on prior research by identifying latent profiles based on interpersonal motives for agency and relatedness, desire for predictability, perceived dependency, and self-efficacy in a sample of people with elevated BPD features (n = 136). Individual differences in overcontrol, undercontrol, …

Resilience Redefined: Exploring The Impact Of Childhood Trauma On The Value Systems Of High-Achieving Corporate Men, Lana B. Henry

Graduate Theses and Dissertations

This qualitative study employed Interpretive Phenomenological Analysis (IPA) to explore how childhood trauma influences the value systems of high-achieving corporate men. In contemporary corporate culture, where stoicism, performance, and independence are often rewarded, little attention is paid to how early adversity informs internal frameworks of meaning, leadership, and success. Semi-structured interviews were conducted with six high-achieving men, all executives and leaders in high-performing industries, who self-identified as having experienced childhood trauma. Data were analyzed using a six-step IPA process and interpreted through the lens of Schwartz’s Theory of Basic Human Values and social constructivism. Findings revealed that childhood trauma deeply …

Assessment Of Mental Health Needs For Chronically Unhoused Individuals Living In A Bridge Housing Community, Isabel Furse Augur

Graduate Theses and Dissertations

Higher rates of psychopathology and substance use are reported in individuals experiencing homelessness compared to the general population, especially in those who are chronically unhoused. Chronically homeless individuals are also less likely to access treatment for these problems because of barriers to care. Addressing housing needs is an important first step in engaging people who are homeless with the care they need. This project focused on assessing the mental health needs of a Housing First community in Northwest Arkansas, which has few barriers for entry but does not provide direct support for mental health. This project adopted a community-based participatory …

End Times: American Mortality, Death Materiality, And Social Death In The 1990s, Jordan A. Savage

Graduate Theses and Dissertations

The United States in the 1990s was marked by pervasive representations of death in popular culture. As death imagery became increasingly visible in entertainment, there was a growing detachment from the embodied, biological realities of death, a tension intensified by the ongoing AIDS crisis. This project explores how death is politicized and how decisions about who lives and dies are shaped by power. I draw on a constellation of theoretical frameworks that collectively illuminate the operations of state-sanctioned death and social abandonment. These include Michel Foucault’s concept of biopolitics, which examines the management of life by state power; Giorgio Agamben’s …

A Grounded Theory Investigation Of The Experiences Of Rehabilitation Administrators, Counselors, And Supervisors Providing Services To Women With Disabilities Experiencing Intimate Partner Violence, Dana Posey

Abstract There is a noticeable gap in the literature as it relates to how rehabilitation and disability service providers have worked with women with disabilities who have experienced intimate partner violence. To address the dearth of knowledge, a qualitative grounded theory study was conducted with 12 rehabilitation administrators, counselors, and supervisors regarding their experiences providing services to women with disabilities who have been in or are in an intimate partner violence relationship. Semi-structured interviews were administered, recorded, and transcribed verbatim in an ongoing manner throughout the process. As data was collected, it was analyzed using NVIVO 15, which is a …

The Black Bombers Of Ghana: Sport, Nation-Building And Pan-Africanism, 1958 To The 21st Century, Kenneth Tagoe

Graduate Theses and Dissertations

Ghana’s Amateur Boxing Team, known as the Black Bombers, has impacted the country’s political and socio-economic development since its formation in 1958. This thesis argues that amateur boxing was one of the sports that Kwame Nkrumah, Ghana’s first president, used to promote nation-building and, more broadly, a Pan-African agenda. The team’s success in international competitions has widely projected Ghana's sporting reputation and reinforced the Pan-African principles of Black pride and excellence in the global athletics arena, and beyond. This thesis traces the origins of amateur boxing and the formation of the Black Bombers, the squad’s participation in international athletics events …

Impact Of Three Professional Development Models (Online, Face-To-Face, And Hybrid) On Bhutanese Inservice Science Teachers' Conceptions Of Aspects Of Nature Of Science (Nos) With Reports Of Translation Of Nos Content Into Classroom Teaching Practices, Pabi Maya Das

Graduate Theses and Dissertations

Having a scientifically literate citizenry is an asset nationally and globally, and knowledge of the nature of science (NOS) is a crucial element in such literacy. Science teachers are a vital link if students are to understand key elements of the NOS, yet teachers themselves often lack knowledge of NOS and how to integrate NOS content into science lessons. Investigating the impact of a series of inservice professional development experiences using three distinct delivery modes (face-to-face, hybrid, online) for teachers in my home country of Bhutan is the overarching goal of the study reported here. The study used a mixed-methods …

Classifying Advanced Persistent Threat Stages And Techniques Via Graph-Enhanced Network Flow Representations, Md Taef Uddin Nadim

Graduate Theses and Dissertations

Advanced Persistent Threats (APTs) are complex, stealthy attacks that involve multiple stages and many attack techniques used in each stage, making them difficult to defend against. Although many solutions can detect APTs, most of them only detect the existence of attack, but cannot produce fine-grained classification over the stage of the APT and the specific attack technique used. Some existing solutions can classify the stages of APT, but few of them provide attack technique classification, and existing work do not provide interpretability for the classification or countermeasures for the attack. In this thesis work, we propose a solution named CAPTure, …

Small Angle X-Ray Scattering Studies Of Collagenase H Mutant, Colh-E416q, Madelyn Millsap

Graduate Theses and Dissertations

Collagenase H (ColH) from Hathewaya histolytica plays a central role in collagen degradation through endopeptidase and carboxytripeptidase reactions. To better understand how its domain architecture supports these functions, we examined the solution structure of a catalytically inactive mutant, ColH-E416Q, using small-angle X-ray scattering (SAXS). The E416Q mutant is catalytically inactive because the glutamate residue at position 416, which normally functions as a general acid/base during catalysis, is replaced by glutamine—an amide that cannot donate or accept protons effectively, thus disabling the proton transfer steps essential for peptide bond hydrolysis. SAXS results indicate that the E416Q substitution leaves overall domain architecture …

Minor League: The Journey To The Show, Collin Anderson

Graduate Theses and Dissertations

When thinking about the path an athlete takes to get to the major leagues, many think of the same process: High School, College, Professional. However, the professional level includes is more than just the MLB or NBA that people would assume. Almost all professional U.S. sports leagues have a minor league system associated with them that nearly all players pass through at one point or another. Through the lens of a documentary, this portion in an athlete’s journey will be spotlighted to show what these leagues do for them, how they help them improve, and how they prepare them to …

Strain Induced Quantum Emitters In Monolayer Wse₂: Fabrication And Characterization Of Dimple Dot Devices, Garrett Maxwell Kitterman

Graduate Theses and Dissertations

Strain induced defects in monolayer tungsten diselenide (WSe₂) give rise to localized exciton funnels, offering a promising approach for the development of tunable quantum emitters. The quantum devices fabricated for this thesis used a modified dimple dot geometry, in which nano indentation creates a strain profile on the monolayer WSe₂. This allows for the funneling of excitons to a confined region. These strain induced funnels enable localized emission from single excitons in WSe₂. Device fabrication was carried out through mechanical exfoliation, dry transfer, and electron beam lithography of Cr/Au gates on a SiO₂ substrate. These devices were then characterized using …

Lifetime Stressor Exposure, Race And Ethnicity, And Habitual Stress Processes: An Evaluation Of Repetitive Negative Thinking And Hair Cortisol Concentration, Harrison Dickens

Graduate Theses and Dissertations

Habitual stress processes are thought to influence acute stress reactivity and stress-related disease. Habitual stress processes have been shown to adapt in response to stressor exposure experienced across the lifespan. The current study seeks to explore whether two habitual stress processes, hypothalamic-pituitary-adrenal (HPA) axis activity and repetitive negative thinking (RNT), were associated with lifetime stressor exposure (self-reported and objective neighborhood-level stressors). Additionally, the current study attempts to quantify how this process may be moderated by race and ethnicity. Participants (N = 134, Mage = 18 [SDage= 1.69], 56.7% female) consisting of White (N = 52), Black (N = 37 ), …

Improved Autofluorescence Lifetime Decay Analysis For Identification Of Cellular Autofluorescence Biomarkers For Label-Free, Single-Cell Assessment Of Mitochondrial Membrane Potential, Olivia Isabel Kolenc

Graduate Theses and Dissertations

Optical imaging of metabolism using the autofluorescence of the metabolic cofactors NADH, NADPH, and FAD has a wide range of sensitivities and the capability to collect a great deal of metabolic information. Multiphoton microscopy (MPM) is a non-invasive, label-free optical imaging technique capable of performing fluorescence lifetime imaging (FLIM) using time correlated single photon counting (TCSPC). However, autofluorescence FLIM presents a challenge in collecting sufficient photons to provide adequate signal to noise ratios (SNR) for analysis. Additionally, the specificity of autofluorescence biomarkers of metabolism has not been well-defined. Contextualizing these autofluorescence measures using established functional biomarkers can improve interpretability of …

The Effects Of Background Child-Directed And Adult-Directed Singing On Reading Comprehension Performance, Agnes Yeboah Amfo-Adu

Graduate Theses and Dissertations

Although music features in speech, such as those found in child-directed speech and song, are known to enhance language processing, the underlying mechanism of this benefit remains unclear. Prior research has primarily compared verbal materials presented in a musical, child-directed style to those in a less musical, adult-directed style, leaving it uncertain whether the benefit stems from the music style of verbal presentation or mere exposure to musical features. This study examined whether the language benefits of child-directed input persist when it is presented as background auditory stimuli rather than the primary focus of cognitive tasks. Experiment 1 found that …
