The Iron Pyramid: Expanding The Iron Triangle To Integrate Safety As A Fundamental Dimension Of Construction Success, Laura Cooley

All Theses

For more than fifty years, construction project success has been judged by staying on schedule, remaining within budget, and completing the planned scope of work—an approach commonly known as the “Iron Triangle” (Barnes, Ph.D., 2006). While these measures are important, they do not capture the full range of factors that determine whether a project truly succeeds.

This study introduces the “Iron Pyramid” (Cooley, 2025), a model that expands the traditional framework by adding a fourth dimension: safety. Safety is understood not simply as regulatory compliance or the absence of injuries, but as a holistic construct encompassing project culture, leadership practices, …

Reliable-Data-Split (Rds): Maximizing Model Potential With Reinforced Selection Strategy, Hoang D. Nguyen, Xuan-Son Vu, Quoc Tuan Truong, Duc-Trong Le

Research Collection School Of Computing and Information Systems

The nexus between data characteristics and parametric models is fundamental for developing effective and reliable artificial intelligence (AI) systems. Mismatches in data properties for model development may lead to deleterious effects on AI model performance in machine learning practice. This paper proposes a Reliable Data Split (RDS) procedure to learn how to select data points that will generalise the target domain adequately by employing prior knowledge of the data generative process. We introduce a reinforced selection strategy using deep reinforcement learning with diverse black box predictors in maximising ensemble rewards as the proxy of model performance potential while maintaining an …

Scalable Graph Indexing Using Gpus For Approximate Nearest Neighbor Search, Zhonggen Li, Xiangyu Ke, Yifan Zhu, Bocheng Yu, Baihua Zheng, Yunjun Gao

Research Collection School Of Computing and Information Systems

Approximate nearest neighbor search (ANNS) in high-dimensional vector spaces has a wide range of real-world applications. Numerous methods have been proposed to handle ANNS efficiently, while graph-based indexes have gained prominence due to their high accuracy and efficiency. However, the indexing overhead of graph-based indexes remains substantial. With exponential growth in data volume and increasing demands for dynamic index adjustments, this overhead continues to escalate, posing a critical challenge.In this paper, we introduce Tagore, a fasT library accelerated by GPUs for graph indexing, which has powerful capabilities of constructing refinement-based graph indexes such as NSG and Vamana. We first introduce …

Effective Transfer Of Tumor Annotations From Hematoxylin And Eosin To Fluorescence Images Of Breast And Lung Tissues, Tianling Niu, Emi Ampo, Julie M. Jorns, Mollie Patton, Tongtong Lu, Dong Hye Ye, Tina Yen, Bing Yu

Biomedical Engineering Faculty Research and Publications

Significance: Accurate transfer of annotations from histological images to fluorescence images is essential in developing deep learning (DL)-based optical imaging systems for intraoperative assessment of tumor margins. Manual annotation is time-consuming, prone to interobserver variability, and impractical for large-scale datasets.

Aim: We present a semi-automated method that can effectively transfer tumor annotations from pathologist-annotated hematoxylin and eosin (H&E) images to fluorescence images captured using microscopy with ultraviolet surface excitation (MUSE). This method is not intended for intraoperative use but rather to facilitate the creation of annotated datasets for DL model development.

Approach: Our semi-automated method consists of nonrigid image registration, …

Factors Influencing Employees’ Ai Adoption Intentions In Occupational Settings, Emma G. Wituk

All Theses

Artificial intelligence (AI) is a burgeoning technology whose development has many implications for organizations and employees. Using a modified version of the Unified Theory of Acceptance and Use of Technology (UTAUT) framework, this study tested performance expectancy (PE; the belief that AI will enhance personal job performance) and prior AI experience (EXP) as predictors of behavioral intention (BI) to use an AI coaching tool, Nadia. We expected both PE and EXP to be positively related to adoption intentions. Additionally, social influence (SI; respondent’s belief that other individuals think they should adopt AI) and facilitating conditions (FC; appropriate infrastructure and adequate …

Barriers To Mindfulness Training Among Athletes: A Transtheoretical Approach, Annabelle L. Thomas

All Theses

Mindfulness, originating from ancient Eastern traditions, involves developing intentional, nonjudgmental awareness of the present moment (Kabat-Zinn, 2012). In recent years, mindfulness-based interventions (MBIs) have gained recognition in Western contexts for improving both well-being and athletic performance (Hut et al., 2021). Despite growing evidence for the benefits, many athletes still do not engage in mindfulness training. Common barriers include limited time (Gao et al., 2024), stigma (De Petrillo et al., 2009), lack of structure (Bühlmayer et al., 2017; Weber et al., 2023), and doubts about effectiveness (Augustus & Zizzi, 2022). This study examined these barriers among NCAA Division I and club …

Environmental Sanitation In Long-Term Care Facilities: A Focus On Regulations And Implementations, Ruwan Dissanayake Dissanayake Mudiyanselage

All Theses

Environmental sanitation is a fundamental component of infection prevention in long-term care facilities (LTCFs), where residents are at increased risk due to advanced age, underlying health conditions, and communal living arrangements. Despite its critical role, significant gaps remain in implementing environmental sanitation procedures and the regulatory frameworks that guide them.

This study combines two components: (1) an across-state regulatory review of environmental sanitation in LTCF regulations and (2) a cross-sectional survey assessing environmental sanitation characteristics of nursing homes (NHs) and assisted living facilities (ALFs) and Rural and Urban LTCF observation study in South Carolina (SC) . For the regulatory review …

Locomotion And Balance Control In A Biped Robot With Continuum Legs And A Kangaroo-Inspired Tail, Gavin A. Platt

All Theses

This thesis work presents the design, testing, and validation of a continuum-legged biped robot equipped with a kangaroo inspired tail for enhanced stability and adaptability. Unlike traditional rigid link robots, this one expands on soft-legged robots and utilizes tendon-driven continuum robots to mimic octopus and kangaroo behavior for locomotion. The robot uses a hierarchical hybrid control framework to implement walking, obstacle avoidance, vaulting, and push recovery behaviors. To test the performance of the robot four sets of experiments were conducted to validate these systems and evaluate how they performed. The results demonstrate stable walking with rhythmic tail load transfer, effective …

Understanding Policy Transfer Under Decomposition And Coordination: Sequential Reinforcement Learning With Relaxation-Based Feasibility Control, Aannand Lal

All Theses

This thesis investigates how decomposition and coordination (D&C) choices influence exploration, learning, and transfer in reinforcement learning (RL) based design frameworks. A unified methodology is developed to evaluate generality under decomposition and to demonstrate sequential coordination on a representative physical task. The generality study holds the underlying physics constant while varying problem presentation - specifically scalarization weights, objective orientations, and feasibility handling. A train-evaluate matrix is constructed in which each trained policy is assessed across all alternative decompositions. Set-based diagnostics quantify generality through exact-match identity, Jaccard similarity of distinct feasible states, total feasible coverage, and Pareto-front quality. Results show that …

Care Starts Before Entering The Clinic – A Holistic Approach To Assessing Primary Care Access At Walter Reed National Military Medical Center, Cory E. Hauptman

All Theses

Walter Reed National Military Medical Center is the world’s largest military treatment facility and the primary provider of healthcare to the military, their families, and military retirees in the Washington DC area. The federal government is legally bound to provide access to primary healthcare services to Tricare enrollees within a 30-minute travel time of their residences. This time constraint has only been applied to the transit period from a patient’s residence to the base where the care is provided and has not accounted for the time it takes a patient to get to the clinic once they arrive at the …

Tools Of The Trade: Exploring Precision Agriculture, Social Media, And Support Services In Modern Farming, Virginia Wayt

All Theses

We need to know more about farmers’ relationships to tools that can help them, including Precision Agriculture (PA) tech from within the field, human service providers (SPs), and social media (SM). To evaluate these relationships, three research projects were conducted. Two were surveys focusing on perceptions - one was on technology and the other was on social media. The technology survey was on vegetable growers and aimed to understand how open and interested they were in PA, which are agricultural technologies that use data to make life easier. They could monitor soil or weather, steer vehicles, limit water, and more …

Feedback Loops: Fly On The Wall, Patrick Barry

Articles

I recently turned to an interesting source to get some feedback on the way I communicate when leading meetings and speaking to large groups: artificial intelligence (AI) tools. Born into a family of fast-talking New Yorkers who don’t always wait for you to finish your thoughts before they jump in with theirs (my mom grew up in Manhattan and my dad grew up in Long Island), I recently realized that I have developed what the linguist Deborah Tannen calls a “high-involvement” conversation style, especially when I take the lead in meetings or teach my classes. I nod as other people …

Developing Standardized Testing Datasets For Benchmarking Automated Quality Control Algorithm Performance With Aquatic Sensor Data, Ehsan Kahrizi

All Graduate Theses and Dissertations, Fall 2023 to Present

Advances in water monitoring technologies have led to a large increase in the amount of data collected from rivers, lakes, and other water systems. However, ensuring that these data are accurate and reliable remains a major challenge. Traditional data quality checks are done manually by a technician, which can be slow, inconsistent, and not practical for real-time monitoring. This research addresses these challenges by developing standardized datasets for testing computer-based methods that automatically detect and correct errors in water data. Using information from the Logan River Observatory in northern Utah, we created a step-by-step process to identify, categorize, and label …

Financial Well-Being Among Self-Employed Older Americans, Cal J. Halvorsen, Byeongju Ryu

Harvey A. Friedman Center for Aging

As people live longer, there has been growing attention in recent years on extending working lives. Although many older adults fully retire, those who continue to work often turn to self-employment—a broad category that includes entrepreneurs, small business owners, consultants, contractors, gig workers, and people who take on side jobs. Rates of self-employment rise sharply with age, with nearly 30 percent of employed adults in their 70s working for themselves—approximately twice the share of those in their 60s.

The Loss Of The Moral Principal: How The Attitude Of School Discipline Changed From The 1950s Through The 1980s, Brendan Webster

Honors Projects

This comparative historical analysis examines the profound ideological transformation of student discipline in American secondary schools between 1950 and 1989. Utilizing a comparative textual analysis of primary source documents published in The High School Journal. This study investigates how administrative philosophy, professional concern, and disciplinary practice responded to the sociological and geopolitical views in the respective decades.

The research identifies a core continuity in the school's role as an agent of social control, but documents a fundamental divergence in the mechanisms used to achieve it. The 1950s view, shaped by mental hygiene and democratic idealism, framed discipline as a developmental …

Perceptions Of Leader Emotional Intelligence During Change: A Qualitative Study Of Middle Managers In Higher Education, Kirk Bennett

Doctor of Business Administration (DBA)

In a world where change is constant, organizations often struggle to adapt. Whether implementing change proactively or responding to external realities, organizational change leaders must navigate the landscape of change with awareness of the potential for follower resistance to derail their efforts. Change and emotion are not easily separated, and change leaders who ignore the emotional realities of change do so at the risk of failure. Leaders who demonstrate emotional intelligence are better equipped to understand and manage the emotions of change in themselves and others. How followers perceive the emotional intelligence of their leaders is crucial to their own …

Ending The Cycle: A New Approach To Decriminalize Mental Illness, Paige E. Kohn

Southern Illinois University Law Journal

Today, America faces a health paradox: the nation’s largest jails are the nation’s largest psychiatric institutions. In a criminal justice system designed for punishment, solutions like mental health units or mental health courts try to address this contradiction. Yet, if mental illness is a health issue, and not a criminal issue, then increased investments in the criminal justice system seem misplaced. Instead, a more promising approach is to stop the mentally ill from entering the criminal justice system at all.

This article presents just that: a new approach to decriminalize mental illness. Viewed under an overarching “health justice” lens, the …

Capstone Projects and Master's Theses

The Latino community in Monterey County faces significant obstacles to accessing hospice care, including language barriers and cultural misunderstandings. Many community members are unfamiliar with available hospice services or hold common misconceptions, such as equating hospice only with dying or abandonment. This capstone project, in partnership with the Central Coast Visiting Nurse Association (VNA), investigated these barriers through interviews conducted at a local senior event. An important outcome of the project was the creation of a bilingual (Spanish and English) resource guide for new Social workers which helps social workers efficiently connect Latino families to appropriate services in their preferred …

Supporting Self-Regulation In Middle Childhood Through Social-Emotional Building, Karen Jimenez

Capstone Projects and Master's Theses

Children in middle childhood, ages 6–12, may struggle to self-regulate their emotions, behaviors, and thoughts. They are becoming more independent, forming deeper friendships, facing greater academic demands, and experiencing more complex situations. Struggles with self-regulation can lead to difficulties in resilience, peer relationships, and school performance, but children who can identify their feelings, understand their emotional triggers, and recognize how these emotions impact their behavior are better able to cope with challenges and stay focused. According to McCabe and Altamura (2011), children with strong social-emotional skills usually have better relationships, more friends, and greater success in school, while those children …

More Than Words: A Parent-Led Approach To Triqui Language Revitalization At Home, Monica Andrade

Capstone Projects and Master's Theses

Preserving indigenous languages is crucial for maintaining cultural identity, strengthening family bonds, and promoting the healthy development of children. For many immigrant Triqui families, the shift to using dominant languages like English or Spanish can lead to language attrition, a gradual loss of their native language when it is no longer spoken regularly at home (McCarty, 2003). To help Triqui parents actively preserve and promote their heritage language, I conducted a workshop specifically for a group of Triqui mothers at the Greenfield Community Center. The workshop provided practical strategies to engage children in everyday Triqui conversations, strengthen intergenerational connections, foster …

Supporting Healthy Eating Habits In Preschoolers, Adrian Arechiga-Martinez

Capstone Projects and Master's Theses

Unhealthy eating habits in early childhood are a growing health concern that has long-term effects on children’s physical and emotional health. Early childhood is an ideal time to support healthy eating habits because nutritious food choices support 1 children’s growth, brain development, and overall well-being. Making healthy food choices also helps prevent diseases such as diabetes and heart disease (Al-Mahshi et al., 2025). However, many young children face limited nutrition education, a lack of parental influence, and inadequate food environments. To address this issue, I created a one-day workshop for children at an early childhood daycare, Ale’s Learn and Play …
