Signals Of Trust: How Privacy Disclosures And Public Responses Drive User Behavior In Digital Markets, Jose Pius Nedumkallel

All Dissertations

This dissertation examines how data privacy practices and complaint response strategies influence user behavior and market outcomes in digital marketplaces. The first study analyzes the impact of Google Play’s Data Safety Label, launched in April 2022 to standardize data collection, third-party sharing, and security disclosures. Grounded in signaling and prospect theories, the label is treated as a compound signal users interpret holistically. A difference-in-differences analysis of 23,877 top Android apps over two years shows that disclosures increase user app adoption. Internal data collection boosts adoption, while third-party sharing reduces it, reflecting behavioral loss aversion. Security disclosures moderate these effects by …

Secure Control And Trust Evaluation Framework For Autonomous Transportation Systems, Grace Muriithi

All Dissertations

This dissertation advances the cybersecurity of hybrid tracked vehicles (HTVs) and ship power systems (SPSs) by developing innovative cyber-attack models and corresponding defence frameworks. First, we formulate stealthy false-data-injection attacks (FDIAs) on HTV energy-management systems as a partially observable Markov decision process (POMDP) solved via deep reinforcement learning. A novel sniffing-based reward function guides the attacker to covertly degrade battery capacity and energy efficiency, which we evaluate using custom stealth–impact metrics and a sliding-window anomaly detector (Isolation Forest with Dynamic Time Warping). Additionally, we model sophisticated control-layer attacks in HTVs, including reinforcement-learning-optimised replay attacks and denial-of-service (DoS) attacks targeting generator-speed …

In this context, nutraceuticals represent an alternative or adjuvant to therapy worthy of exploration. The reviewed literature highlights the anti-carcinogenic activity in selected nutraceuticals, marjoram, thyme and persimmon, considering their phytochemical constituents and secondary metabolites. Metabolomic profiling using the Biolog Phenotype Mammalian …

Pseudo-Soft-Switching Switched-Capacitor Drive Circuits For Small-Scale Dielectric Actuators, Yanqiao Li

Dartmouth College Ph.D Dissertations

Applications including micro-robotics and haptics have motivated extensive exploration of dielectric actuators due to their high bandwidth and high efficiency at cm and mm scales. To maximize their benefits, dielectric actuators, including piezoelectric and electrostatic actuators, typically require high driving voltages, ranging from 100V to several kV. Generating such high driving voltages presents a challenge for drive circuits, particularly when powered by a small battery. Dielectric actuators are predominantly capacitive in most circumstances, necessitating the drive circuits to deliver and recover reactive energy for efficient operation. In some applications, such as micro-robotics, the drive circuits may need to have a …

How Was Rehab? A Follow-Up To A Randomized Effectiveness Control Trial Of A Brief Acceptance And Commitment Therapy Protocol For Inpatient Detoxification Patients, Alexander J. Twohy

Dissertations

Residential treatment for Substance Use Disorders (SUD) is a common treatment modality. However, the literature is sparse on modifiable predictors that affect change during the residential treatment stay. Acceptance and Commitment Therapy (ACT) has been shown to be an effective treatment for SUDs. Weststrate et al. (2023), in a randomized controlled effectiveness trial, compared ACT plus medication management to medication management during detoxification. The addition of ACT increased consumer satisfaction and ACT skills use, while decreasing psychological inflexibility and reducing withdrawal symptoms.

This study explored whether the brief ACT intervention had impacts during participants' subsequent residential stay. Forty out of …

Coding Manual: Analyzing Semistructured Interview Data For Master Narratives, Jayson Seaman, Cindy Hartman, Andrew D. Coppens

Faculty Publications

This coding manual accompanies a methodological reorientation in narrative identity research, one that challenges the field’s prevailing “protagonist bias” — the assumption that first-person autobiographical accounts are the primary or most valid source for identifying cultural master narratives as psychological resources. While much psychological research has centered on how individuals narrate their own lives, this approach can obscure the ways that broader cultural narratives are circulated, reinforced, and contested through discourse beyond the self. This method provides researchers with a systematic approach for identifying how master narratives operate across multiple narrative levels, often outside of biographical storytelling.

Unraveling Snow And Rain Contributions To Streamflow Through A Methodological Investigation On Cold And Warm Season End-Members, Rachel Grena

Boise State University Theses and Dissertations

Water supply and demand are encountering unique challenges in the western United States as climate change impacts the availability of water resources. Much of the west relies on high mountain snowpack to maintain consistent streamflow throughout the dry, warm season months. Temperatures often rise above freezing in the cold season, diminishing the snowpack size, and altering the timing of snowmelt. As droughts become more frequent, water managers are increasingly concerned about the risk of reduced summer streamflow. To understand changing hydrologic patterns, this study utilizes phase changes in precipitation, specifically the distinction between cold and warm season precipitation, and their …

Open Educational Resources In Elder Refugee Esl Contexts: Instructor And Administrator Perspectives, Alison Elliott

Boise State University Theses and Dissertations

Open Educational Resources (OER) offer a promising solution to educational disparities through their free, adaptable, and shareable nature, fostering collaboration and innovation in pedagogy. While OER, alongside Open Educational Practices (OEP), has seen a vibrant and growing integration within K-16 foreign language contexts, its application within adult English as a Second Language (ESL) education remains significantly under-researched. Adult ESL contexts, especially those serving refugees, present unique challenges: learners have experienced trauma, interrupted education, and have urgent practical English needs, while adult educators contend with inconsistent training, demanding part-time workloads, and a fragmented professional ecosystem that limits professional development and research …

Social And Economic Gradients Of Resource Transfer Behavior In Gorongosa, Mozambique, Karl J. Mertens

Boise State University Theses and Dissertations

Why do people who experience the same environmental and social conditions vary so much in their resource transfer behavior? This dissertation addresses that question through examination of behavioral variation in subsistence horticulturalists in the dry tropical forest bufer conservation area of Gorongosa National Park in Mozambique. In this region of moderate and acute food shortages at both household and regional levels, individuals face similar challenges of addressing social and resource uncertainty yet respond with marked behavioral variation that cannot be explained solely by diferences in wealth, kinship, or reciprocity patterns.

Using a Behavioral Reaction Norms (Dingemanse et al., 2010) (BRN) …

Aging Effect On Effective Connectivity Within The Prefrontal-Motor Network And Postural-Related Muscle Responses During Dual-Task Paradigms, Jiahao Pan

Boise State University Theses and Dissertations

Falls are a significant global public issue for older adults, leading to severe health and social impacts. To understand the underlying mechanism of increased fall risk with aging, loss of postural automaticity has been suggested as increased prefrontal cortex and motor cortices activation, as well as worse balance performance in response to the secondary cognitive task. However, the interaction within these cortical regions and its effects on postural-related muscle responses are poorly understood. This dissertation investigated age-related changes in effective connectivity within the prefrontal-motor network, postural related lower limb muscle response, and biomechanical characteristics in response to the secondary cognitive …

Considerations For Developing Dna-Templated Dye-Aggregate Systems, Simon Kristopher Roy

Boise State University Theses and Dissertations

Molecular excitons have been the subject of significant research interest for nearly 100 years. Molecular excitons arise when conjugated organic molecules (dyes) are excited such that the resulting excitation is delocalized over multiple dyes in a wavelike manner. The shared excited states that allow the excitation energy to hop between molecules is of particular interest for applications that can make use of the wavelike properties of excitons, including applications in quantum information science. A key challenge for developing materials for these advanced applications is to overcome the knowledge gaps associated with precisely templating dyes with spatial control of their aggregation, …

Sustainability: Buzz Word Or Future Of Fashion? Measuring The Feasibility Of Outright Sustainability Among Fast Fashion’S Biggest Agents, Ryan Miller

Apparel Merchandising and Product Development Undergraduate Honors Theses

Abstract

The fashion industry is currently experiencing unsustainable rates of pollution within its supply chains. The rapid increase in demand for short lead times perpetrated by large-scale retailers has led to hazardous practices negatively affecting both the environmental conditions and working conditions of producing countries. With this increased pressure, relationships between brands and suppliers have become untenable. Limited transparency and imbalanced power dynamics at the hand of the industry’s leading retailers require restructuring in order to build more sustainable and equitable supply-chain practices. Further, governmental regulation is currently limited in its capacity to enforce sustainable business practices on a global …

Risk Perceptions And Water Governance: Experiences Of Irrigation Companies In The Great Salt Lake Basin Of Northern Utah, United States, Bailey M. Holdaway

All Graduate Theses and Dissertations, Fall 2023 to Present

Irrigation companies are important water management entities in the Western US. However, these companies often face barriers when managing water. Particularly as the state of Utah grows and water resources are drying, there is much finger pointing at those in irrigation and agriculture for better water management. However, pointing fingers without the participation of these companies often does not lead to effective water management outcomes. Therefore, it is important to understand the role of these irrigation companies, and particularly how they are approaching water management.

I set out to understand the role of these irrigation companies, specifically in the Great …

To measure this, the study compares changes in trust over for …

An Embodied Social Demography For Trans And Nonbinary Workers, Jesse Ezra Shircliff

All Graduate Theses and Dissertations, Fall 2023 to Present

Recently, the separation of “sex” and “gender” has seen intense debate in public discourse, stemming from skepticism about the social sciences and the measurement and study of gender specifically. Meanwhile, the United States population is becoming more gender diverse, with roughly 1 in 200 people now identifying as trans gender or gender nonbinary (that is, as a gender that is different from that person’s sex assigned-at-birth or outside of the sex-gender binary). This growing population experiences numerous disadvantages across social life, including obstacles in one particularly important aspect of the American Dream: the right to have and hold a job. …

Optimizing Delphinium And Larkspur Through Timing And Protective Cultivation Methods For Cut Flower Production, Nicholas Kirwan Volesky

Habitat Selection Analysis Of Mule Deer To Determine Efficacy Of The Coyote Bounty Program In Utah, Xaela M. Walden

All Graduate Theses and Dissertations, Fall 2023 to Present

Mule deer populations have been declining over the past couple of decades in many parts of the western United States. Often times, predators are blamed for the decreases in deer populations. Because of this, wildlife managers implement programs focused on reducing the number of predators on the landscape in an attempt to increase deer populations. However, predator removal programs have had mixed results, thus further investigation is needed to determine if coyote removals by the public through a bounty program have a positive effect on mule deer populations. My study investigated whether coyote removals through the bounty program in Utah …

"Why Does Coach Do That?" Exploring Influences Of Coach Behavior In Non-Elite Women's Artistic Gymnastics, Katherine Vernay Adams

All Graduate Theses and Dissertations, Fall 2023 to Present

This two study dissertation explores coaching in women's artistic gymnastics, as the sport has been criticized for harsh and controlling coaching methods.

While there was no direct link, those with a history of mistreatment tended to struggle more with managing their emotions. The second study tested whether coaches view controlling coaching as more acceptable for younger or more advanced gymnasts. The results showed that neither age nor skill level made a difference—controlling coaching was generally viewed as unacceptable, while supportive …

A Numerical Investigation Of Erection Bridging In Double-Pitched Open-Web Steel Joists, Logan Joshua Ward

All Graduate Theses and Dissertations, Fall 2023 to Present

Open-web steel joists are truss members used to support roofs and floors in steel buildings. They are commonly used because they are lightweight and inexpensive to manufacture on a large scale but have a large load carrying capacity due to their depth. Because of this depth, these joists are very unstable laterally, which is addressed by adding bridging (horizontal or diagonal) members between them to resist rotation of the joists. One of the bridging types is erection bridging, which is used to prevent a joist from buckling laterally while steel erectors are traversing it during construction.

The current erection bridging …
