Centering Access: Reimagining Basic Writing Through Critical Disability Frameworks, Jason Burton Mccormick

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Despite decades of scholarship arguing otherwise, developmental writing spaces are still often treated as places of deficit in higher education. This deficit positioning emerges in the ways the courses are discussed (as barriers and burdens to graduation), the way learners are imagined (being “unprepared” for college work), and the way placement is understood as punishment. Developmental educators continue to fight this stigma, but rely on stories of students “overcoming” rather than acknowledging that the stigma is a product of the institution and its discriminatory norms, not the offering itself.

My work reimagines the developmental writing classroom as an essential liminal …

James And Paul: Conflict Or Continuity, Brian Allan Elensky

Doctoral Dissertations and Projects

This dissertation investigates whether the Epistle of James presents a fundamentally different gospel from Pauline theology, a claim advanced by Robert Eisenman and other scholars who portray James as the leader of a rigorist, non-resurrectional, sectarian movement. The study employs a forensic investigative model shaped by the researcher’s experience as a police officer, combining historical-grammatical exegesis of James with analysis of key New Testament texts, early Christian witnesses such as Eusebius and Hegesippus, and modern scholarship on James, Paul, and the Dead Sea Scrolls.

The research concludes that James does not oppose Paul but complements him. James 2:14–26 rejects a …

Building Human-Aware Ai: Learning From And Assisting Human Decision-Makers, Saumik Narayanan

McKelvey School of Engineering Graduate Student Theses & Dissertations

As artificial intelligence systems become more capable, they are increasingly used not only as standalone problem-solvers, but as systems that learn from and interact with humans. In these settings, success depends not only on the strength of the model in isolation, but also on how well it fits the humans it is trained on or deployed alongside. This dissertation argues that human heterogeneity is a central ingredient in the design of effective human-aware machine learning systems. Rather than treating differences between people as noise to be averaged away, I show that variation in human expertise and preferences can provide useful …

Benefits Of Traffic Reprofiling For Delay Sensitive Networking, Jiaming Qiu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Deterministic networking systems, such as Time-Sensitive Networking (TSN) and Deterministic Networking (DetNet), require strict end-to-end delay guarantees while efficiently utilizing limited network resources. Conventional approaches typically focus on fixed traffic profiles, which can lead to suboptimal resource utilization in scheduling or admission control problems. This dissertation investigates traffic reprofiling—the proactive reshaping of traffic arrival patterns—as a complementary mechanism for improving both resource efficiency and delay performance under strict service guarantees. The dissertation consists of three parts. The first part studies bandwidth minimization under hard delay constraints for Service Curve Earliest Deadline First (SCED) schedulers. We show that traffic reprofiling can …

Acquired Von Willebrand Syndrome From Pathological Cardiovascular Flow, Alice Liu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Acquired von Willebrand syndrome (AVWS) is a bleeding disorder characterized by the loss of high molecular weight von Willebrand factor (VWF) multimers. It is often associated with a wide range of underlying diseases, including individuals who receive mechanical circulatory support (MCS) and myeloproliferative neoplasm (MPN) patients, yet the mechanical mechanisms remain incompletely understood. In circulation, VWF undergoes force-dependent conformational changes that regulate its susceptibility to cleavage by the metalloprotease ADAMTS13. While elevated shear has long been believed to the main cause, pathological VWF cleavage cannot always be explained by shear alone, suggesting more factors are at play. The goal of …

Lateral Habenula And Dorsal Raphe Neurons Signal Value Computations In Multi-Attribute Decision-Making, Yang-Yang Feng

McKelvey School of Engineering Graduate Student Theses & Dissertations

Decision-making is a fundamental part of adaptive behavior and can be compromised in psychiatric illness. Humans and animals are continuously presented with objects and opportunities as options to decide between. One challenge is that these options may independently vary along multiple dimensions or attributes that we care about. This can include attributes of physical reward, such as amount, delay, or uncertainty. When these attributes are present, the possibility of an abstract, cognitive reward, advance information to resolve uncertainty, may also motivate our decisions. It is unclear how the brain makes these subjective decisions, trading off between these multiple attributes based …

Revisiting Visualization Literacy: What Standardized Assessments Reveal And Conceal Across Instruments, Cultures, And Ai Systems, Saugat Pandey

McKelvey School of Engineering Graduate Student Theses & Dissertations

Data visualizations are now a primary medium for public communication, scientific reasoning, and decision-making. By transforming complex data into accessible graphical forms, visualizations are widely assumed to make information comprehensible to broad audiences. Yet the ability to accurately read, interpret, and critically evaluate a visualization, what researchers call visualization literacy, is neither uniform nor universal. It is a learned, multidimensional skill shaped by prior exposure, educational opportunity, and context. While the field has developed standardized instruments to measure visualization literacy, these tools were built under narrow assumptions: participants are typically paid, English-speaking, and recruited from Western online panels. When any …

Deep Learning Enhanced Multimodal Endoscopy For Colorectal Cancer: From Real-Time Software Architecture To Clinical Response Assessment, Haolin Nie

McKelvey School of Engineering Graduate Student Theses & Dissertations

Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the second leading cause of cancer-related deaths in the United States, with a concerning rise in incidence among younger adults. Clinical management is currently shifting toward organ-preserving ``watch-and-wait" strategies for rectal cancer and precision endoscopic resection for early-stage polyps. However, current diagnostic standards, including white-light colonoscopy (WLC) and magnetic resonance imaging (MRI), lack the resolution and functional specificity to accurately assess the invasion depth of precancerous polyps or to reliably distinguish post-treatment fibrosis from residual viable tumor. This dissertation advances colorectal cancer diagnostics through three integrated contributions: CPU-optimized photoacoustic …
