Indigenous-Industrial Heritage: Centering Indigenous Voices In Minnesota's Iron Range, Larissa A. Juip

Dissertations, Master's Theses and Master's Reports

Industrial heritage refers to the material remains, sites, landscapes, and practices associated with industrial and extractive activities. As a field, it has historically been concerned with the conservation, management, and interpretation of industrial sites and activities and forms a central narrative within Minnesota's museums. Yet such accounts often privilege object-centered narratives while silencing the presence, knowledge, and contributions of Indigenous and Descendant communities, obscuring their enduring relationships to extractive landscapes. In recent decades, critiques of traditional industrial heritage approaches have identified gaps in the discipline related to the exclusion of marginalized populations, including Indigenous Peoples. Minnesota is home to eleven …

The Music Education Gender Divide At The University Of Northern Iowa, Abigail Wendland

Honors Program Theses

While anyone with proper training can direct a band well, the definitive stereotype in music education is that male directors are the default. Women face a multitude of challenges when going into the field because of this stereotype, which is the direct result of decades of prejudice that are now historical tradition. These challenges include the perceived need to adopt a male persona while on the podium, the challenges of working as a public school band director while being a mother, and the guilt that accompanies many women in the field. Obstacles such as these have strongly contributed to the …

Comparing Custom And Transfer-Learning Cnn Models For Chest X-Ray Classification: Evaluating Performance And Scalability With Kubernetes Orchestration., Christopher Anich

ICT

Chest radiography (CXR) is the primary imaging tool for respiratory diseases, but interpretation can be time-consuming and requires expertise. This study compares a small custom CNN (Victorio) with three transfer-learning models (MobileNetV2, EfficientNet-B0, ResNet-50) for three-class CXR classification (normal, pneumonia, tuberculosis) and evaluates deployment on a Kubernetes cluster. Using a balanced dataset of ~13,500 CXRs, models were trained with ImageNet pre-training and from scratch. Transfer-learning models achieved near-perfect accuracy (99–100%) and AUROC, while the custom CNN reached 87–91%. Explainability analyses confirmed models focused on relevant pulmonary regions. Kubernetes deployment showed low latency, with most delays due to service overhead rather …

Predicting S&P Corporate Credit Ratings Using Financial Ratios And Machine Learning: An Analysis Of European Non-Financial Companies., Gabriele Frattaroli

ICT

This study investigates the prediction of multi-class S&P corporate credit ratings for European non-financial firms from 2010 to 2024 using a machine learning framework grounded in financial fundamentals. To ensure robustness and generalizability, the analysis excluded the Year variable, which was identified as a source of data leakage. After this correction, non-linear ensemble models demonstrated a clear advantage over linear baselines. The top-performing Random Forest model achieved a weighted F1-score of approximately 0.60, more than doubling the performance of the Logistic Regression benchmark used as a baseline (0.26), with most misclassifications concentrated in adjacent rating categories. This indicates that while …

Language Assessment In Pediatric Speech-Language Pathology, Sierra Kay Buscher

Honors Program Theses

Standardized language assessments of children are commonly used to diagnose language disorders, yet these tools are often normed on a narrow demographic of monolingual, middleclass, white children. This narrow normative data has led to misdiagnosis of children who fall outside of the norm created. Studies highlight how cultural, linguistic, and normative test biases disproportionately affect children who speak non-mainstream dialects, are multilingual, have disabilities, or are from lower socioeconomic backgrounds. The findings of this literature review calls attention to a disconnect between research, policy, and clinical practice, indicating that SLPs rely on standardized assessment tools out of accessibility or in …

The Practice Of The Communal Pot -Olla Común- By Low-Income Women As A Strategy To Face Hunger On The North Coast Of Peru, Ricardo M. Sabogal-Suji

Electronic Theses and Dissertations

During the COVID-19 pandemic in Peru, the ancient practice of the communal pot (olla común) has become even more popular. This consists of neighbors spontaneously organizing themselves to collect food to cook for needy people. Peru is characterized by informality and ontological precarity that persist over time regardless of the political context, leading to endemic food insecurity. The pandemic crisis further aggravated the situation of Peruvians, leading the Peruvian government to support the growing communal pots that had traditionally been autonomous. The food crisis has persisted in post-pandemic times, which is why communal pots have multiplied, many of them becoming, …

Assessing Trophic Pathways In The Southern Indian River Lagoon Using Fatty Acid Markers, Joedeelee Rigdon

Electronic Theses and Dissertations

The Indian River Lagoon (IRL) comprises over 200 Km of the Florida’s east coast and is a bar-built estuary making up one of the most biodiverse estuarine environments in North America. Toxins produced by increasingly frequent harmful algae blooms in the IRL are found throughout the food web, from zooplankton to fish, to apex predators. The impact of species characterized as harmful algae can be traced using fatty acid markers, as phytoplankton and algae that make up HABs produce characteristic poly-unsaturated fatty acids (PUFA), which have conservative ratios between trophic levels. This study measured the fatty acid composition of two …

A Virus Of The Mind: The Neurological Impact Of Neonatal Herpes Simplex Virus Infection, Abigail Jeanne Dutton

Dartmouth College Ph.D Dissertations

The ability of herpes simplex virus (HSV) to establish lifelong latency in sensory neurons makes it one of the most pervasive viruses worldwide. Although most HSV infections are asymptomatic or cause limited cutaneous symptoms, some give rise to serious central nervous system (CNS) manifestations. Both primary HSV infection and subsequent reactivation events can cause viral replication and spread within the brain, ultimately leading to pathologic inflammation and direct CNS damage. In addition to fulminant presentations of HSV encephalitis, subclinical HSV CNS infections have been implicated in neurodevelopmental, cognitive, and neurodegenerative impairment. To model the lifelong effects of subclinical HSV infection, …

Leveraging Epigenomics And Transcriptomics To Develop High-Dimensional Biomarkers Of Neuroinflammation, Steven C. Pike

Dartmouth College Ph.D Dissertations

Neuroinflammation is a critical physiological phenomenon implicated in most neurological disorders, either as a cause or a consequence of pathology. Our understanding of neuroinflammation is limited by the inability to directly profile the cells of interest. Thus, developing biomarkers of neuroinflammation is clinically urgent as we know neuroinflammation correlates with patient outcomes and treatment success. The recent advances in “omics” technologies, particularly epigenomics and transcriptomics, provides the opportunity for high-dimensional profiling of biospecimens for potential biomarkers. Within this dissertation, I demonstrate that biomarkers obtained from “omics” platforms can detect neuroimmunological phenomena in clinical and preclinical settings. In chapter one, DNA …

Optical Methods For Time-Resolved Dosimetry And Oximetry Of Ultra-High Dose Rate Radiation Therapy, Megan A. Clark

Dartmouth College Ph.D Dissertations

Radiotherapy (RT) is a cornerstone method used to treat over 50% of the 2 million new cancer diagnoses each year in the United States. The success of RT directly relies on an optimal balance between maximizing the dose to the tumor while minimizing dose to surrounding normal tissues. Achieving this balance is often challenging due to underlying radiation transport and the presence of anatomical constraints that limit the beam delivery geometry. In turn, minimizing healthy tissue toxicity prevents use of a more aggressive tumor killing approach, and even in curative cases may decrease the patient’s quality of life due to …

The Inevitability Of Adaptability – Comparative Contributions To Understanding Originalism, Anna Conley

Emory International Law Review

What can comparative law teach us about originalism as a constitutional interpretation method? After synthesizing existing comparative analyses, this article seeks to redefine comparative law’s role in understanding originalism. When defining originalism strictly to require adherence to fixed original meaning, originalism is not used by courts anywhere in the world. Instead, courts use history purposively to understand the intent behind constitutional text as one of many methods of interpretation. Comparative works suggest historical constitutional interpretation has a complex relationship with rights, politics and culture.

Comparative law can provide not only descriptive understandings of originalism but also interrogate its mandate that …
