The Final Girl Without The Slasher: Final Girls, Gender, And Community In Psych, Cassidy Crosby

All Graduate Reports and Creative Projects, Fall 2023 to Present

This thesis focuses on the “Final Girl” trope, a hallmark of slasher films of the 1970s and 1980s, as it appears in detective procedural television show Psych to analyze what changes in the trope’s usage says about broader changes in American culture. I engage with two key episodes, “Scary Sherry: Bianca’s Toast” and “Tuesday the 17^th,” which contain the program’s most direct engagements with the Final Girl trope. Ultimately, I conclude that Psych rejects the hyperindividualism embedded in the Final Girl and some of the trope’s more binary gender norms, while also failing to interrogate other aspects of …

A Provable Semi-Infinite Programming Approach For Solving Dynamic Nash Games, Tyler C. Gardner

All Graduate Theses and Dissertations, Fall 2023 to Present

Many engineering problems must account for the non-cooperative decisions and actions of multiple players. These problems can be modeled within a game-theoretic framework. The approach herein is to model problems as Nash games, convert them to semi-infinite programs, and leverage provable semi-infinite algorithms to solve the original problem. A particular algorithm that leverages off-the-shelf solvers is used to solve four low-dimensional benchmark problems successfully. Two types of linear quadratic dynamic games are then investigated: ones where each player’s problem is convex and ones where at least one player’s problem is nonconvex. Within each type, variations based on information structure, communication …

Adapting To Change In Amenity-Oriented Communities: Innovative Strategies For Shifting Social And Environmental Needs, Emma L. R. Epperson

All Graduate Theses and Dissertations, Fall 2023 to Present

Amenity-oriented communities are places with significant and desirable natural amenities that are highly visited and plentiful within the Intermountain West. These high rates of visitation create complex challenges such as congestion in recreation spaces and in towns and increase costs of living. These communities are typically rural and often do not have the resources, funding, or infrastructure to combat these challenges. Although tourists provide financial stability and other amenities to these towns, local wellbeing is highly impacted. Outdoor recreation and the nature connections derived from outdoor experiences are major contributors to wellbeing in amenity communities. This research investigates the changes …

Aquatic Habitat Representation For Robust Water Resources Management And Fish Conservation Decision-Making, Gregory C. Goodrum

All Graduate Theses and Dissertations, Fall 2023 to Present

We rely on rivers to provide water supply, flood control, and hydroelectricity for people and to sustain aquatic ecosystems. The development of dams and reservoirs to provide water for people did not consider environmental impacts to rivers, leading to widespread decline of freshwater species and habitat. Improving environmental outcomes of water management is needed to protect and restore aquatic ecosystems. However, rivers are complex and variable, making them difficult to represent as objectives for water management. This dissertation explores approaches to improve aquatic habitat representation and environmental objectives for water resources management and river conservation and restoration.

Traditionally, this approach has been limited to High-Performance Computing (HPC) environments, leaving some researchers, students and educators without resources to explore cutting-edge simulations and analyses. This work attempts to show that powerful scientific simulations and real-time analysis can be made available by using more easily obtained commodity hardware. This approach may enable a broader participation in the scientific computing discovery process.

In this paper, we explore how advanced simulation and visualization frameworks …

Warfare And Woodlands: Tracing Environmental And Military History In The Hürtgen Forest, Cedar Williams

All Graduate Theses and Dissertations, Fall 2023 to Present

This thesis explores what happens when war enters a forest. From 1944 to 1945, American and German forces fought a long, brutal battle in the Hürtgen Forest near Germany’s western border. The dark, wet, and heavily wooded terrain made the fighting unusually difficult. Soldiers struggled not just with enemy fire, but with freezing rain, deep mud, low visibility, and constant stress. The forest shaped how the battle unfolded and intensified its hardships.

But the war’s impact on the forest continued long after the soldiers left. Unexploded bombs and artillery shells littered the ground. During a heatwave in 1947, many of …

Exploring Biotic And Abiotic Drivers Of Ecosystem Properties: The Influence Of Waterbirds And Photodegradation On Wetland Ecosystems, Lindsay Miller

All Graduate Theses and Dissertations, Fall 2023 to Present

Wetlands provide a wide range of valuable ecosystem services: these are benefits from the environment that support human well-being, such as water filtration, fish and bird habitat, and shoreline protection. Despite their importance, wetlands are among the most threatened ecosystems, facing increasing pressure from natural and human activities. To better predict the future of wetlands and guide effective management and restoration practices, we need to understand the various forces shaping their ecological properties. In this thesis, we examined the influence of two forces: waterbirds and photodegradation (the process by which sunlight breaks down plant material). To explore each of these …

Protecting The Dreams Of Indigenous Psychology Trainees: Stories Of Culturally Competent Supervision, Erica Ficklin
