Protocol Transformations Across Osi Network Stack Layers For Attack, Evasion, And Defense, Nathan Tusing

All Dissertations

Network endpoints frequently contend with errors and deviations within protocols. Many factors account for these deviations including noise, tampering, and algorithm implementations. Intermediate nodes are expected to modify instantiated protocols and not guarantee correctness. This ability to modify traffic enables all sides of network security to alter security and performance properties of protocols, and we define this intermediary modification of an instantiated protocol as a transformation. Protocol transformations traverse layers of the OSI reference model and changes a protocol's time series byte sequence. Within this thesis, we show that this framework applies to multiple domains and protocols. Common examples of …

Soil Organic Matter Processes From The Treetops To The Clay Particle: The Role Of Climate, Minerals, And Organic Matter Chemistry In Soil Carbon Accumulation And Stability, Jessica G. Murray

All Graduate Theses and Dissertations, Fall 2023 to Present

Soils store more carbon than plants and the atmosphere, yet release ten times more carbon dioxide (CO₂) to the atmosphere than human activities each year. Small shifts in the balance of soil carbon storage and soil carbon emissions could make climate change less severe, by acting as a sink for the carbon plants pull from the atmosphere, or make climate change worse, by releasing even more planet-warming greenhouse gases. The processes governing whether soils store or release carbon depend on tiny soil microorganisms which convert plant carbon to soil organic matter, releasing CO₂ in the process. In …

Pavlovian Conditioned-Reinforcer Training As A Means Of Reducing Impulsive Choice, Emma Visser

All Graduate Theses and Dissertations, Fall 2023 to Present

Impulsive choice is associated with a host of human maladaptive behaviors warranting investigations aimed at reducing impulsive choice. Pavlovian conditioning was explored in 22 male Wistar rats. The experimental group was exposed to a stimulus that signaled a large delay-reduction to an food, whereas the control group experienced a stimulus that was controlled by a random schedule that did not predict food. Subsequently, a test of conditioned reinforcement was conducted, indicating a difference in conditioning between groups. Finally, a test of impulsive choice failed to find effects of training on impulsive choice.

Moose Movement In An Urbanizing Landscape, Lucian R. Mcdonald

All Graduate Theses and Dissertations, Fall 2023 to Present

Humans disturb the environment in specific places and at specific times. As wildlife learn to navigate these disturbances, they react as they would to the risk of predation. Wildlife biologists can identify where and when these disturbances will lead wildlife to congregate by comparing geospatial data, such as metrics that represent vegetation, topography, or other environmental conditions, to known locations of the animal(s) in question. In Chapter I, I discuss the impact of human disturbances, like urbanization and roads, on wildlife behavior. In Chapter II, I compare the risk of moose-vehicle collisions (MVCs) to moose selection of urbanized landscapes to …

Investigating The Biochemical Aspects Of Meat Tenderness, Chandler D. Stafford

All Graduate Theses and Dissertations, Fall 2023 to Present

Of all the attributes that define beef's eating quality, tenderness stands out as one of the most important. Previous studies have shown that consumers are willing to pay a premium for beef that is guaranteed to be more tender and are more likely to purchase that product repeatedly. Yet, due to the influence of numerous internal and external factors, controlling and predicting tenderness remains to be difficult. However, among these factors, meat aging is the primary contributor to end-product tenderness, as it is recognized for breaking down muscle tissue via enzymes present within the muscle. The activity of these enzymes …

However, a prominent Beat culture was also present on the West Coast throughout the 1950s and 1970s. The thesis explores how the West influenced the literature and art produced by Beats during this time.

Ecological Interactions Of Cougars, Deer, And Wild Pigs In The Central Coast Range, California, Mitchell A. Parsons

All Graduate Theses and Dissertations, Fall 2023 to Present

Wild pigs are an introduced species in the Americas that negatively affect ecosystems in many ways. Previous research has documented their negative effects on water quality and vegetation and their potential to spread disease among wildlife, domestic animals, and humans. However, how wild pigs affect predator-prey interactions between native wildlife has received little attention. This research explores multiple interactions between wild pigs, a native predator (cougars), and a native prey (black-tailed deer). First, I studies cougar diet to understand how frequently pigs are used as prey. During this project, I also placed wildlife cameras at cougar killed prey to monitor …

Detecting Community-Level Ethnic Variation Through Classic Vernal Style Rock Art, Victoria Ramirez

All Graduate Theses and Dissertations, Fall 2023 to Present

The Uinta Basin in Northeastern Utah was where farming first took hold in the far north of western North America. This shift from hunting to farming saw the rise of many farming communities among the Fremont people. These communities left behind stunning rock art known as the Classic Vernal style. Recent studies suggest that these communities were made up of two different groups who came from the Four-Corners area around AD 300, bringing farming with them. This idea means that different cultural groups may have created the Classic Vernal style rock art in the Uinta Basin. By looking closely at …

From Pasture To Plate: Striking An Omega Balance Between Grass-Fed And Grain-Fed Beef Ribeyes - Fatty Acid Composition, Minerals, Soil, And Forage Analysis, Travis Earl Statham

All Graduate Theses and Dissertations, Fall 2023 to Present

Most beef cattle in the US are feedlot-finished where intensive feeding of grains is used to increase weight and yield; however, a minority are raised in grass-fed operations that use exclusive pasture, rangeland, and hay for feeding, possibly leading to benefits for the land, soil, ecosystems, forages, and the meat itself. These operations use a variety of methods, and the goal of this was to recognize differences in the soil and forage metrics to help understand the resulting meat fatty acid composition and mineral content. We collected these samples from 78 sets of farmers while testing 25 sets of grain-fed …

Immune Variation Across Different Contexts In Non-Model Systems, Kwanho Claudia Ki

All Graduate Theses and Dissertations, Fall 2023 to Present

The immune system is important to an animal’s survival against disease-causing agents and physical injuries. Accordingly, many resources are required to maintain and activate the immune system (such as energy). However, as these resources also need to be shared with other important systems of the body, the portion of resources that can be allotted to the immune system is variable. Thus, many different factors may alter how well the immune system operates. My dissertation sought to understand what sorts of factors can lead to changes in the immune system. Reptiles are known to have a very robust immune system. Therefore, …

Genomic Selection For Dwarf Bunt Resistance In Winter Wheat, William Krause

All Graduate Theses and Dissertations, Fall 2023 to Present

Dwarf bunt (DB), caused by the pathogen Tilletia controversa J.G. Kühn [as 'contraversa'], is a fungal disease that poses yield and grain quality risks to winter wheat (Triticum aestivum) production in the Intermountain West and abroad. The infection replaces the grain with a collection of spores that are spread by wind during the following harvest. In addition to wheat, DB also infects other cereal grains and wild grasses. Genomic selection (GS) is a plant breeding method that can determine percent infection of related varieties by using phenotypic data and genetic data within a prediction model. A panel …

Designing Technology-Enriched Learning Environments: The Effects Of An Agent-Based Computer Model On Biology Students' Understanding Of The Covid-19 Pandemic And The Nature Of Models In Science, April Sullivan

All Graduate Theses and Dissertations, Fall 2023 to Present

Science education researchers have called for increased attention to the science practice of modeling to engage students in authentic scientific inquiry. A major challenge to integrating the modeling practice into science instruction is that students tend to conceptualize models as static end-products of research rather than generative tools for theory-building. Engaging students in using computer models, specifically agent-based computer models (ABMs), to explain and predict scientific phenomena could improve students' understanding of models in science. In this design-based research project I investigate the effects of an ABM-supported learning environment on high-school biology students' understanding of the COVID-19 pandemic and the …
