Improving Operating Room First-Case On-Time Starts And Reducing Turnover Times: A Quality Improvement Project, Ashley Cote

Master's Theses and Capstones

Abstract

Background: Delays in first case on-time starts (FCOTS) contribute to decreased operating room (OR) efficiency, increased healthcare costs, workflow disruptions, and reduced staff and patient satisfaction. Evidence suggests that standardized workflows, improved communication, and Lean Six Sigma methodologies can improve perioperative efficiency and reduce delays.

Local Problem: Baseline data from a local OR microsystem demonstrated an FCOTS rate of 77%, below the organizational benchmark of 80%. Root cause analysis identified inconsistent preoperative workflows, communication gaps, and variable staff adherence to standardized processes as primary contributors to delayed first-case starts.

Methods: A quality improvement project utilizing the Define, Measure, Analyze, …

The Effects Of Environmental Complexity On Brain Development And Personality Expression In Western Hognose Snakes, Gokulan Nagabaskaran

Theses and Dissertations (Comprehensive)

There is growing interest in snake cognition, personality, and welfare as more snakes are kept as pets, yet little research has been conducted. The effects of enrichment and environmental factors have been well documented in other taxa, and recent evidence suggests that snakes may benefit in similar ways. This dissertation investigated the impact of environmental and social enrichment on personality expression, personality stability, and brain development. Western hognose snakes (Heterodon nasicus) were used as the model species, as they are a popular choice in the pet trade. This allows the research to be readily translatable to husbandry practices of many …

Science Fiction Cinema And The Technological Sublime: Spectacle And The Infinite From Early Cinema To Digital, David Jackson Dr.

Theses and Dissertations (Comprehensive)

This dissertation examines how science fiction cinema constructs and reimagines the technological sublime in the twentieth century: the experience of awe, terror, and admiration provoked by human-made power and scale. Drawing on the philosophical foundations of the sublime in Edmund Burke and Immanuel Kant and extending through Leo Marx’s and David E. Nye’s theorization of the technological sublime, I propose an aesthetic mode in which representation inflected with affect translates technological spectacle into examinations of humanity’s role and agency in the face of overwhelming technologized worlds and in some cases, even the universe itself.

Through three distinct historical periods …

Cultivating Diversity In Sustainable Food Systems: Black Farming And Lived Experience In Rural Southern Ontario, Kadeem Jerofy Morgan-Adamson Mr.

Theses and Dissertations (Comprehensive)

This research examines the lived experiences of Black food growers in rural Southern Ontario to understand how their perspectives challenge dominant narratives of rurality and inform broader discussions on food sovereignty in Canada. Grounded in postcolonial theory, the study highlights how historical dispossession and persistent inequities shape the access of Black communities to land and resources. Using a mixed-methods approach that includes surveys, semi-structured interviews, and reflexive journaling within a community-based research framework, the study documents the barriers Black food growers face. These include limited land access, insufficient funding, inadequate training pathways, and experiences of racial isolation in rural contexts. …

When Civilians Involve Themselves In Crime Control: Do Perceived Police Legitimacy And Trust In The Police Predict Support For Vigilantism And Citizen’S Arrests?, Charlotte T. Parque

Electronic Theses & Dissertations (2024 - present)

Recent cases in which civilians involved themselves in the crime control process have garnered divided reactions, with some people supporting and others disapproving the civilians’ actions. Although existing research shows that perceptions of the police predict support of civilians involved in crime control, exact directions of the effects conflict. I address these conflicting findings by examining how people conceptualize police legitimacy and trust in the police, whether those conceptualizations align with scholarly definitions of legitimacy and trust, and explore if the two constructs differentially predict support of vigilantism. Additionally, I explore whether people approve of two types of civilian crime …

Evaluating The Potential Of Genomic Selection For Grain Yield And Yield Component Traits In South Dakota Winter Wheat, Dante Koupal

Electronic Theses and Dissertations

Wheat (Triticum aestivum L.) is a major cereal crop worldwide, but recent gains in grain yield (GY) have not kept pace with projected demand. GY is a highly quantitative trait with low heritability that requires multi-year, multi-location phenotyping, limiting selection efficiency. Targeting higher heritability yield component traits, such as kernel size and weight, and incorporating them into the genomic selection (GS) pipeline has the potential to accelerate genetic gain for GY. The objectives of this study were to (i) understand the relationship between GY and the kernel-size traits, including thousand kernel weight (TKW), kernel length (KL), kernel width (KW), and …

Impacts Of Management Practices And Soil Properties On Free-Living Nitrogen Fixation In Eastern South Dakota, Laura Galvan Nuevo

Electronic Theses and Dissertations

Free-living nitrogen (N) fixation (FLNF) may represent a sustainable pathway to supplement crop N demand in agroecosystems, yet edaphic and management factors regulating this process under field conditions remain poorly understood in the Northern Great Plains. Using 15N2 direct method to quantify potential FLNF (pFLNF) and baseline FLNF (bFLNF), this thesis investigates how crop rotations (2-, 3-, and 4-year systems), tillage management (conventional vs. no-till), cover cropping, and soil properties affect the potential of free-living diazotrophs to supply N via FLNF in a long-term no-till corn-based system in Southeastern South Dakota. A two-year field study evaluated pFLNF across four growing …

Theses and Dissertations

School counselors are First-Responders as the role and responsibilities continue to increase and the needs of the school community changes. Diversity has notably increased within the last century in school settings. While, the impact of the COVID-19 crisis has shed light on the gaping and persistent inequities faced by marginalized school communities, the heightened racial crisis of 2020 serves as an additional impact to the students within vulnerable communities. School counselors are expected to support students in navigating the impact that these crises bring. The demand for school closure forced students to shift to online platforms. The intersection of the …

Ai Vs. Genai: Combating Llm Generated Prescription Fraud With Transformer Based Detection Models, Ankitha Vokkaleri Shankarappa

Selected Full-Text Master Theses 2021-

The rapid evolution of Large Language Models (LLMs) has introduced a sophisticated new vector for healthcare fraud: the generation of high-fidelity, synthetic medical prescriptions. Traditional fraud detection systems, which rely on rule-based engines and basic statistical anomalies, are increasingly ill-equipped to identify these AI-generated forgeries that mimic the structural and clinical logic of authentic records. This thesis presents a robust detection framework using Transformer-based architectures to distinguish between human-authored Medicare Part D prescriptions and fully synthetic records generated by GPT-4.

The research was conducted across two distinct phases: an initial pilot study using 4,000 samples and a rigorous validation stress …

Systematic Study On Preparation And Characterizations Of High Performance Bimetallic Pt-Co/Sba-15 Catalyst In N-Heptane Isomerization, Talib M. Albayati, Khalid A. Sukkar, Nisreen S. Ali, Mahir A. Abdulrahman, Basheer A. Abdulhussein, Issam K. Salih, Narges Elmi Fard

ASEAN Journal on Science and Technology for Development

Bimetallic catalysts were prepared by deposition of 1% of loading of (Pt-Co) onto SBA 15 support using heterogeneous reaction for enhancing hydroisomerization and promoting hydrocracking for the decomposition of n-heptane. The catalytic performance of the catalysts was subsequently evaluated thereafter. Characterization of the prepared catalysts was done by various techniques, which include XRD, FTIR, BETBJH, SEM/EDS, and TEM. The temperature range studied for this catalytic activity was 250 to 400 °C, at atmospheric pressure in a plug-flow reactor. The experimental setup kept a very rigorous control over the temperature, flow rate for the reactants, and pressure, while gas chromatographic techniques …

Elucidating The Results Of Multiple Linear Regression: A Systematic Literature Review And Monte Carlo Comparative Simulation Study Of Relative Importance Methodologies, Oscar Gaytan

Human Resource Development Theses and Dissertations

Theory-supported multiple linear regression models are often formed to assess the impact of HR practices on organizational performance and other desired outcomes. Several methods are available to determine which predictors contribute most to said outcomes. However, researchers may make agential cuts in the method selection phase, with their histories, experiences, or perspectives on relative importance measures influencing their decisions. When multiple measures are employed, discordant results leave room for differing interpretations, potentially leading to suboptimal guidance. Correlation-Adjusted coRrelations (CAR) scores offer a unique alternative to established relative importance methodologies. However, a systematic literature review indicated that no large-scale comparison of …

High Temperature Creep Deformation Mechanism Of Fe28.2ni18.8mn32.9al14.1cr6 High Entropy Alloy And Its Modified Alloys, Edwin S. Jiang, I. Baker

Dartmouth College Ph.D Dissertations

Fe28.2Ni18.8Mn32.9Al14.1Cr6 eutectic high entropy alloy exhibits a good combination of room-temperature and high temperature properties, including tensile strength, ductility, and corrosion resistance, making it a promising candidate for structural applications in extreme environments. However, the creep deformation behavior of this alloy— and high-entropy alloys (HEAs) in general—remains insufficiently understood. This dissertation systematically investigates the high-temperature creep deformation mechanisms of Fe28.2Ni18.8Mn32.9Al14.1Cr6 and its derivatives.

Creep mechanisms and associated microstructural changes were examined across a wide range of strain rates using strain-rate jump and constant-stress tests. Two dominant regimes were identified: dislocation glide/solute-drag at low strain rates, and dislocation climb at high …

Immune Suppression And Epigenetic Reprogramming In Epithelial-Mesenchymal Transition, Hanxu Lu

Dartmouth College Ph.D Dissertations

Epithelial-mesenchymal transition (EMT) is increasingly recognized as a dynamic spectrum of cellular programthat contributes to tumor progression, metastasis, and therapeutic resistance. Rather than existing as discrete epithelial or mesenchymal phenotypes, tumor cells undergo intermediate EMT states in which epithelial and mesenchymal features are partially and variably expressed. In this thesis, I studied EMT state heterogeneity through two complementary and integrated dimensions: tumor-immune interactions and the dynamic remodeling of epigenetic programs across the EMT spectrum. Using a clonal EMT model derived from the murine triple-negative 4T1 mammary carcinoma cell line, including epithelial, intermediate, and mesenchymal states that are stably maintained in …

The Influence, Dependency, And Targeting Of Fatty Acid Uptake In Er+ Breast Cancer, Abigail E. Goen

Dartmouth College Ph.D Dissertations

Estrogen Receptor-positive/ Human Epidermal Growth Factor 2-negative, breast cancer (ER+/HER2- BC) is the most prevalent subtype of BC, impacting millions of individuals. Although early screening and treatment with endocrine therapy has greatly enhanced survival, this subtype sustains a steady increase of risk for recurrent disease for decades after diagnosis, indicating the persistence of residual cancer cells that are capable of maintaining dormancy for >20 years prior to metastatic outgrowth. Dormant cells reprogram metabolic pathways which can be profoundly influenced by the tumor microenvironment in promoting quiescence or proliferation. Fatty acid oxidation dependency has been noted as a hallmark of drug …

Governing Agroecological Transitions: Landscape Legacies, Participation, And Socioecological Change In The Northeastern United States, Kristen Jovanelly

Dartmouth College Ph.D Dissertations

Agroecological transitions are often presented as purposeful shifts toward more resilient, equitable, and ecologically sustainable landscapes. In practice, these transitions unfold through histories, ecological feedback, institutional arrangements, and contested forms of participation. This dissertation examines how these forces shape what agroecological transitions become, for whom, and with what socioecological consequences across urban and working landscapes in the northeastern United States.

Drawing on historical and critical analysis, ecological modeling, greenhouse experimentation, ethnographic fieldwork, and institutional analysis, I trace transition through urban forests, community-garden seed banks and soils, temperate agroforestry systems, and a participatory tree nursery. Analyses of urban greening and agroforestry …

Ecce Leadership Development: Supports, Barriers, And Identity Formation, Andrea Weidele

Open Access Dissertations

Early childhood care and education (ECCE) leadership development is not given the attention it deserves. Despite the proven link between high-quality ECCE programs and positive societal outcomes, leadership development within the sector is significantly under-resourced. Because program quality is inherently tied to leadership efficacy, there is an urgent need to investigate the supports and structures that foster effective ECCE leadership. This study addressed that gap by using a qualitative multiple case study to explore how six ECCE program leaders of licensed ECCE programs from a New England state describe their leadership development, including supports and barriers they encountered and how …

Extending Low-Frequency Traveling-Wave Propagation In A Water-Filled Cylindrical Waveguide Using Active Impedance Control, William Slater

Open Access Dissertations

This dissertation investigates extending the frequency range over which a one-dimensional, plane traveling wave can be generated in a water-filled, steel-walled waveguide under ocean temperature and hydrostatic pressure conditions. The wave guide considered is a thick-walled, steel cylinder filled with a water/glycol mixture with a transducer at each end and a hydrophone array along the length. One transducer excites a plane wave while the other cancels reflections, resulting in a traveling wave in the waveguide. The current (open-loop) measurement system is advertised to generate traveling waves for low frequencies where only 3.4% of a wavelength can be measured (kL …

Optimizing Markov Chain Monte Carlo Algorithms For Fairness, Scalability, And Interpretability In Electoral Redistricting, Madhukara Kekulandara

Open Access Dissertations

Gerrymandering undermines democratic representation by manipulating electoral district boundaries to dilute the political influence of targeted communities. While Markov Chain Monte Carlo (MCMC) based redistricting algorithms have become a standard computational tool for detecting partisan gerrymandering, their effectiveness in addressing racial gerrymandering and their scalability on modern computing systems remain limited. This dissertation advances the theory and practice of algorithmic redistricting by optimizing MCMC-based approaches across three dimensions: racial fairness, computational efficiency, and interpretability.

First, this work introduces the Partial Map MCMC algorithm, a novel redistricting method designed specifically to address racial gerrymandering under the legal framework of Section 2 …

Colorectal Cancers With Distinct Metastatic Potential Trigger Divergent Early T Cell Responses, Marwa Ahmed Saad

Student Theses and Dissertations

The intestinal mucosa harbors the largest immune compartment in the mammalianbody, where resident and recruited immune cells must maintain tolerance to commensal and dietary antigens while preserving their ability to mount effective responses against pathogens and malignant transformation. Uncontrolled epithelial proliferation leads to colorectal cancer (CRC), the second leading cause of cancer-related deaths worldwide. More than 85% of human CRC cases arise from accumulating sporadic or hereditary mutations in the tumor suppressor genes Apc, Tp53, Smad4, and the oncogene Kras. Although immune checkpoint blockade has transformed the treatment of certain solid tumors, most CRCs, particularly those with a proficient mismatch …

Noncanonical Roles Of Hepatitis B Virus Precore Rna In Reverse, Mengyin Zhang

Student Theses and Dissertations

Hepatitis B virus (HBV) is a partially double-stranded DNA virus that replicates through reverse transcription. Transcription from the HBV core promoter generates two genome-length RNAs: pregenomic RNA (pgRNA) and precore RNA (pcRNA). pcRNA contains the entire pgRNA sequence plus an additional 32 nucleotides at its 5’ end that include the precore start codon, enabling translation of the precore protein, the precursor of the secreted HBV e antigen (HBeAg). Whereas pgRNA is translated to produce core and polymerase and serves as the template for reverse transcription by cis-acting HBV polymerase, pcRNA has long been considered unable to support HBV DNA synthesis. …

Collaboration And Co-Management Ahead Of Permitting: Understanding How Actors And Their Interactions Lead To Non-Optimal Shoreline Projects, Juita-Elena (Wie) Yusuf, Mariana Saitgalina, Michelle Covi

School of Public Service Faculty Publications

Living shorelines are widely promoted as nature-based solutions to coastal erosion and wetland protection, yet hardened shoreline structures continue to dominate even in jurisdictions with explicit policy mandates prioritizing living shorelines. In this research, we examine why non-optimal shoreline modification outcomes persist in Virginia (USA) despite a regulatory framework designed to promote ecological alternatives. We use primary data from interviews with wetlands board members, marine contractors, and nonprofit organizations and findings from a secondary survey of shoreline property owners to analyze shoreline management as a multi-sector collaborative decision-making process. Findings show that shoreline outcomes are shaped less by individual regulatory …

Feddot: Defending Federated Learning Against Overwhelming Targeted Attacks, Priyesh Ranjan, Ashish Gupta, Federico Coro, Sajal K. Das

Computer Science Faculty Research & Creative Works

Federated Learning (FL), which facilitates collaborative model training and protects users' privacy, has drawn great interest from the research community. With FL, participants train their models on local data and submit the corresponding updates for aggregation to a server. While concealing the identities of the participants, FL may attract adversaries in order to hamper the underlying model. In this paper, we propose an FL framework, FedDOT, to defend against adversaries performing targeted attacks. FedDOT incorporates two powerful defense algorithms, Maximum Spanning Tree based attacker detection (MSTAD) and Densest graph-based attacker detection (Density-AD), which leverage correlation between weight updates and graph …

Adversarial Robustness In Biomedical Time-Series Models, Rohan Tiwari

Bioengineering Theses

This study investigates adversarial vulnerabilities in deep learning models for biomedical time-series classification across two clinically important modalities: electrocardiography (ECG) and electroencephalography (EEG). Using the MIT-BIH Arrhythmia and CHB-MIT seizure datasets, I evaluate time-domain attacks (FGSM, PGD), Fourier-domain constrained attacks, and learned spectral perturbations designed to reveal modality-specific sensitivity patterns. Across both tasks, a consistent trend emerges low-frequency components (0–5 Hz) constitute a dominant axis of adversarial vulnerability, with perturbations in this range producing the steepest degradation in classification performance. In ECG models, protecting the physiologically relevant QRS band (5–20 Hz) significantly improves robustness, whereas EEG models remain highly sensitive …

From Weapon To Shield: Risk And Special Intent In South Africa’S Case Against Israel, Heidi Matthews

Articles & Book Chapters

South Africa’s genocide case against Israel at the International Court of Justice is best understood as a mode of judicial self-help, instead of a method of undermining Israel’s sovereignty. The fact that South Africa claims standing – based partly on its own obligation to prevent genocide – has been largely overlooked in scholarly discussions of the case. However, centring this fact allows us to see that it is Israel’s alleged intentional creation of circumstances that give rise to a serious risk of genocide in Gaza that constitutes the core of South Africa’s case. The plausible existence of such a risk …

Rethinking Transnational Adjudication: The Normative Foundations Of Institutional Design, Sanctions-Related Arbitration Frameworks, And Digital Recognition Systems, Avaskhan Asanaliyev

SJD Dissertations

This dissertation examines how emerging judicial and dispute resolution architectures can sustain cross-border commerce, investment, and enforcement in the post-Soviet space and beyond, at a time of institutional fragility, geopolitical tension, and rapid digitalization. Drawing on the experience of Kazakhstan, Russia, Ukraine, and key global hubs, it argues that institutional innovation in courts, arbitration, and enforcement mechanisms is central to rebuilding credible governance frameworks for international business. It does so through three interconnected studies that together explore the evolution of modern adjudication: first, through the transplantation of a common law judiciary model within a civil law state; second, through the …

Pork, Parties, And Power: Money Politics In Japanese Political Parties, Maya Maranto

HMC Senior Theses

This thesis examines the proposition that the LDP utilizes money politics more than opposition parties in Japan, which could explain why the LDP has remained largely dominant since 1955. Focusing on the House of Representatives elections in 2017, 2021, and 2024, I analyze eight case studies, examine the University of Tokyo-Asahi Shimbun Elite Candidate Survey covering over 90 percent of candidates, and quantitatively analyze party manifestos. I operationalize money politics as reliance on support organizations, support for infrastructure and agriculture, forestry, and fisheries, and support for regional funding. I find that, all measures taken together, the LDP remains the most …
