Abstract

Statistical Methods for Assessing Individual Oocyte Viability Through Gene Expression Profiles

By

Michael O. Bishop

Utah State University, 2017

Major Professor: Dr. John R. Stevens

Department: Mathematics and Statistics

Oocytes are the precursor cells to the female gamete, or egg. While reproduction may vary from species to species, within humans and most domesticated animals, the oocyte maturation process is fairly similar. As an oocyte matures, there are various processes that take place, all of which have an effect on the viability of the individual oocyte. Barring outside damage that may come to the oocyte, one of the primary reasons …

Management Of Predators, Prey, And Aviation Safety At Naval Air Station Patuxent River, Maryland: Can Coyotes Help Reduce Deer Strike Hazards?, Robert Lewis

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

In the past 100 years, coyotes (Canis latrans) have expanded their range eastward. During their expansion, coyotes hybridized with gray wolves (Canis lupus) in the north and red wolves (Canis rufus) in the south. Coyotes were historically occupants of the plains, but now may be found in environments as varied as the sagebrush steppe, deserts, swamps, and inner cities. St. Mary’s County, MD, home to Naval Air Station Patuxent River (Pax River), was one of the last counties in the country to be colonized by coyotes. Pax River is a research and development/flight test and evaluation center, and houses numerous …

Hanging From The Poplar Tree: Kanye West And Racism In Internet Folklore, Magen Olsen

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Folk ideas regarding African-Americans in nineteenth century America fueled racially charged stereotypes that served to promote segregation into the 1960s. Despite the belief of many Americans that the Civil Rights movement has ushered in an era of “postracism,” artifacts of digital culture prove that racism is still prevalent in American culture. Members of online social groups spread rumors and memes of popular African-American figures to propagate old racist stereotypes and spread conspiracy rumors among younger audiences.

Folklorists Bill Ellis, Gary Fine, Véronique Campion-Vincente, and Patricia Turner provided foundational scholarship on rumors, conspiracy theories, and how they divide ethnic groups in …

The Influence Of Wind Energy Development On Columbian Sharp-Tailed Grouse (Tympanuchus Phasianellus Columbianus) Breeding Season Ecology In Eastern Idaho, Matthew C. Proett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus; CSTG) has experienced range-wide population declines, primarily as a result of habitat loss or degradation, and currently occupies <10% of its historic range. Expansion of wind energy developments across the remaining occupied CSTG range has been identified as a potential threat to the species. To assess the potential influence of wind energy development of CSTG breeding season ecology, I captured and radio-marked 135 female CSTG drugin 2014-2015 at leks located between 0.1-13.8 km from wind turbines in restored grassland habitats. Using radio-telemetry, I monitored 147 nests and 68 broods and developed models to assess the influence of wind turbines, roads, habitat features temporal factors, and precipitation on CSTG nest site selection, nest survival, brood success, and chick survival. Female CSTG in my study selected nest sites in grassland habitats where >30% of the canopy cover in the nesting core use area was composed of forbs (i.e., broadleaf plants). The strength of selection for this habitat type increased as its availability increased on the landscape. Nest survival increased with higher visual obstruction readings (i.e., concealment) at the nest bowl and in grassland habitats where forb cover exceeded 30% in the nesting core use area. I did not detect an influence of wind turbines or …

Effects Of Changing Environments On Survival Of A Widely Distributed Ungulate, S Andrew Sims

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wildlife species distributed over large areas of land inhabiting varying environments are experiencing shifts in their home ranges due to human expansion and climate change. As these species home ranges shifts out of familiar, critical habitat they are forced to interact with novel environments, which in turn affects the species population demographics. In order to manage and conserve these species accordingly, specifically in a time of large-scale change, it is imperative that we add to current understandings of how they interact with various environments. Furthermore, frequently generating short-term predictions of demographic drivers will allow for conservation and management insight that …

A Stochastic Model For Water-Vegetation Systems And The Effect Of Decreasing Precipitation On Semi-Arid Environments, Shannon A. Dixon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Current climate change trends are affecting the magnitude and recurrence of extreme weather events. In particular, several semi-arid regions around the planet are confronting more intense and prolonged lack of precipitation, slowly transforming these regions into deserts. Many mathematical models have been developed for purposes of analyzing vegetation-water interactions, particularly in semi-arid landscapes. Most models are based on the average behavior of the system as a whole, and how it is influenced by external changes. These models may be termed "macro-scale" models. Other models have concerned themselves with the interactions between individuals, in this case the interactions between individual plants …

Establishing A Kinetic Assessment Of Reactive Strength, Talin Louder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three neuromuscular characteristics are identified in Sheppard and Young’s model of agility: concentric strength and power, bilateral symmetry, and reactive strength. Measures of reactive strength attempt to model the neuromuscular regulation of tissue stress and strain. The Coefficient of Reactivity (CoR) is the first known assessment of neuromuscular reactivity. The CoR was developed as an assessment of neuromuscular performance in drop jumping. The construct validity of the CoR was placed in question when Warren Young proposed the Reactive Strength Index (RSI). The RSI improved the theoretical validity of reactive strength assessment since it included a component measure (ground contact time) …

Do Data Structures Matter? A Simulation Study For Testing The Validity Of Age-Period-Cohort Models, Sun Young Jeon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Age, period, and cohort are three temporal dimensions that can make unique contributions to social and epidemiological changes that occur in populations over time. However, while the theoretical underpinnings for each temporal dimension are well established, the statistical techniques to assess the distinctive contributions of age, period and cohort are controversial. Unless questionable assumptions are imposed on the data, traditional linear regression models are incapable of estimating the independent contribution of each temporal dimension due to the linear dependence between age, period and cohort (A=P-C). Two recently developed methods, Hierarchical Age-Period-Cohort (HAPC) and Intrinsic Estimator (IE) models, enable researchers to …

Wolf In Sheep’S Clothing: Model Misspecification Undermines Tests Of The Neutral Theory For Life Histories, Matthieu Authier, Lise M. Aubry, Emmanuelle Cam

Wildland Resources Faculty Publications

Understanding the processes behind change in reproductive state along life-history trajectories is a salient research program in evolutionary ecology. Two processes, state dependence and heterogeneity, can drive the dynamics of change among states. Both processes can operate simultaneously, begging the difficult question of how to tease them apart in practice. The Neutral Theory for Life Histories (NTLH) holds that the bulk of variations in life-history trajectories is due to state dependence and is hence neutral: Once previous (breeding) state is taken into account, variations are mostly random. Lifetime reproductive success (LRS), the number of descendants produced over an individual's reproductive …

Relative Effects Of Sleep Hygiene Behavior And Physical Exercise On Sleep Quality, Austin Dopp

Undergraduate Honors Capstone Projects

Numerous studies have shown the relationship between sleep and overall health. A common measure of sleep is sleep quality which has been shown to be influenced by a variety of factors such as physical activity, diet, stress, social engagement, cognitive stimulating, and sleep hygiene behaviors. Data was analyzed from a previous study to determine whether trying to change one’s sleep would improve sleep quality and if this was more effective than physical exercise. A group of 104 individuals, randomized to the treatment group, were asked to log their daily activities, via smartphone app, within these six behavioral domains for six …

The Impact Of High School Extracurriculars: Similarities And Differences In Sense Of Community Among Competitive, Performance, And Participatory Activities, Erica M. Hawvermale

Undergraduate Honors Capstone Projects

Extant research links high sense of community in adolescence to adaptive outcomes such as enhanced motivation, self-efficacy, and coping ability (Battistich, Solomon, Watson, & Schaps, 1997; Vieno, Perkins, Smith, & Santinello, 2005; Henry & Slater, 2007), as well as reduced stress, anxiety, and depression (Chipuer, Bramston, & Pretty, 2002). In light of these findings, the present study was designed to assess the relationship between high school students’ participation in extracurricular activities and their perceptions of sense of community, enjoyment, and commitment, as well as the aspects of these organizations that help to facilitate feelings of community. Study 1 participants (N= …

From Disaster To Sustainability: The Story Of The Pacific Groundfish, Matthew Richards

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This paper reviews the circumstances that led to the collapse of the Pacific groundfish fishery and the steps that fishery managers took to curb over-harvesting and bring the fishery back to sustainability. Fishery managers utilized various management tools such as a vessel buyback program, regulatory mechanisms, and market strategies to improve the available data on the fishery, improve safety for fishermen, and reduce harvest rates and overcapitalization. By employing a diverse range of measures, managers developed a system by with they successfully balanced conservation objectives and minimized adverse impacts to fishing communities. Overcapitalization and overharvest continue to degrade the health …

Evaluation Of Long-Term Effects Of Mild Traumatic Brain Injury On Visual Motor Control Of Ncaa Division I Football Athletes, Kathryn Delost

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Context: Current concussion evaluation assessments rely largely on static measures that may not detect subtle changes in behavior. Dynamic evaluation, such as visual-motor tracking tasks, may reveal subtle and meaningful changes in motor behavior post-concussion. Objective: This study compared measurements of performance regularity over a time series (approximate entropy; ApEn), which was derived from a visual-motor tracking task performed before concussion, post concussion, and at one month, three months, and six months post concussion. ApEn values were compared for number of previous concussions and playing position groups. Design: ApEn values were collected from the visual-motor tracking task, and history of …

Dietary Supplementation With Tart Cherries For Prevention Of Inflammation-Associated Colorectal Cancer In Mice, Ashlie Hunter

Undergraduate Honors Capstone Projects

The cherry fruit is a nutrient-dense food with comparatively low caloric content and significant amounts of key nutrients and bioactive food chemicals. Much of the health benefit of cherries is attributed to their high amounts of anthocyanins, which have anti-oxidant and anticancer properties that contribute to changes in cell signaling pathways involved in inflammation, carcinogenesis and angiogenesis. In this project, we aimed to determine whether dietary supplementation with tart cherries prevents colon tumor development in mice consuming a Western diet compared to a prudent diet. Previously, our research team developed the Total Western Diet (TWD) for mice to emulate typical …

Pairing Of Anaerobic And Aerobic Treatment Of Petroleum Wastewater, Zachary Fica

Undergraduate Honors Capstone Projects

The objective of this project was to treat petroleum refinery wastewater using a combination of anaerobic and aerobic processes, namely an Up-flow Anaerobic Sludge Blanket (UASB) reactor paired with a Rotation Algae Biofilm Reactor (RABR), respectively, to produce a treated effluent. The treatment method developed needed to produce a cost-effective and efficient way to decrease nitrogen, phosphorous, total suspended solids (TSS), and COD concentrations to below State of Utah limitations. It was demonstrated that RABR treatment was capable of reducing effluent concentrations of nitrogen, phosphorus, and TSS to State of Utah limitations. RABR treatment did not significantly reduce COD from …

Caffeine And Acetaminophen Concentration And Other Water Quality Parameters Along The Middle To Lower Bear River, Autumn Slade

Undergraduate Honors Capstone Projects

Various water quality parameters were measured at seven sites along the Middle to Lower Bear River and compared across the sites, to past data and to set standards in Utah and Idaho. Much of the data was comparable to past data with most state standards being met. However, nitrate was above indicator level for half of the sites, and turbidity is a problem at the last two sites. Also, chloride and unionized ammonia are at high levels by the last site. Overall, the river tended to decrease in water quality as it moved downstream, with dams like at Cutler Reservoir …

A Deeper Look Into The Vastus Medialis: A Stabilizer For The Knee, Connie Nicole Barnes

Undergraduate Honors Capstone Projects

Anterior cruciate ligament tears are one of the most common injuries that occur, especially in female athletes. It requires surgery and months of physical therapy to get these athletes back in playing condition. The angle of women’s hips and lack of strength of inner quadriceps muscles enhances the risk of injuries to the knees. One specific muscle that is known for being a stabilizer of the knee and may help in preventing ACL tears is the vastus medialis. By understanding what exercises activate this muscle the most, conditioning plans and preventative workouts need to be created to help female athletes …

Teaching Social Studies Through Drama, Colin Anderson

Undergraduate Honors Capstone Projects

Educators and researchers have long discussed methods for improving student achievement in the social studies and history. Research on student attitudes reveals that the social studies suffers from a lack of interest among students. Common complaints among students are that the subject is tedious, does not relate to their lives, is not particularly useful for their future careers, is repetitive, or that it is simply boring (Schug et al., 1982). Even when students recognize the utilitarian value of skills they learn from social studies / history, they rarely express an interest in the subject (Chiodo, 2004). After reviewing the body …

Delay Discounting Mechanisms In Eating Disorders: A Call To Arms, Rowan Crowder

Undergraduate Honors Capstone Projects

Delay discounting, or temporal discounting, is a measure of impulsivity that describes the devaluation of a reinforcer as a function of its receipt in time. Several studies have shown that individuals diagnosed with a variety of behavioral maladies such as obesity/over-eating, substance abuse, cigarette smoking, heavy drinking, and problematic gambling exhibit greater discounting rates. To be specific, they are more impulsive and less willing to wait for delayed reinforcement than healthy controls. Several of these studies have found that obese women discount at a steeper rate than non-obese women, similar results have been shown in binge eating disorder. The relationship …

Spatial And Behavioral Patterns Of Captive Coyotes, Jeffrey T. Schultz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Environmental enrichment is a technique used at many captive animal facilities that can improve the well-being of their animals. It seeks to enhance habitat features and promote natural behavior by providing a variety of practical ways for captive animals to control their environmental settings, especially during stressful circumstances. Enclosure features, such as shelter structures, are one tool that promotes wild behavior by adding complexity to an enclosure’s physical environment. Enrichment efforts for captive wildlife are most effective when they are specialized to the biological needs of the animals. Human activity may alter captive animal behavior and utility of enclosure features, …

The Revival Of America's First Genre: Exploring The Panther Narrative's Feminist Principles In Post-Revolutionary War America, Abigail Bentley

Undergraduate Honors Capstone Projects

America’s victory in the War of Independence posed new challenges for the men who drafted the Constitution. Gender roles shifted dramatically during the war, creating a new attitude about women’s roles in the new republic. Before the Constitution was ratified, women like Abigail Adams advocated for women to have a more active role in the new nation. Radical literature regarding women’s roles also became a driving force in the movement. The Panther Narrative used the resurgence of America’s first genre, the captivity narrative, to combine the new republic’s obsession with personal freedom and radical ideas about gender spheres. The anonymous …

Spatial Ecology Of Coyotes And Cougars: Understanding The Influence Of Multiple Prey On The Spatial Interactions Of Two Predators, Peter J. Mahoney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The coyote (Canis latrans) has expanded throughout much of North America over the past century following the regional extirpation of apex predators. These highly adaptable canids can occupy a variety of landscapes from the rainforests of Central America to the dense, human-dominated urban centers of the United States. As a generalist predator, coyotes can capitalize on a variety of food resources, including anthropogenic subsidies such as domestic livestock and food tailings at landfills. These tendencies often bring coyotes in direct conflict with humans, forcing managers to consider mitigation strategies ranging from the targeted removal of problem individuals to …

Evaluating Habitat-Based Niche Requirements And Potential Recruitment Bottlenecks For Imperiled Bluehead Sucker (Catostomus Discobolus), Bryan C. Maloney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Changes to rivers that alter physical and thermal habitat may cause fish population abundance to decline, due to fewer individuals maturing and entering the adult population. The Weber River has become highly degraded with many dams and diversions altering fish habitat, river volume, velocity, and temperature, and limiting movement between reaches. Bluehead suckers (Catostomus discobolus) occupy only 47% of their historical range and the genetically-distinct Weber River (northern UT) population is declining and contains few young, juvenile fish. My objectives were to determine whether spawning and rearing habitat available in the Weber River may be limiting bluehead sucker …

Strategies For Increased Lactic Acid Production From Algal Cake Fermentations At Low Ph By Lactobacillus Casei, Tom J. Overbeck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

We explored using de-oiled algal biomass (algal cake) as a low-value substrate for production of lactic acid in fermentations with Lactobacillus casei, and strategies for increasing lactic acid production at low pH. L. casei 12A algal cake (AC) fermentations showed carbohydrate and amino acid availability limit growth and lactic acid production. These nutritional requirements were effectively addressed with enzymatic hydrolysis of the AC using α-amylase, cellulase, and pepsin. Producing 0.075 g lactic acid per g AC from AC digested with all three enzymes. We explored heterologous expression of the cellulase gene (celE) from Clostridium thermocellum and the …

Sclerocactus Wetlandicus: Habitat Characterization, Seed Germination And Mycorrhizal Analysis, Kourtney T. Harding

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Uinta Basin hookless cactus (Sclerocactus wetlandicus) is a threatened species native to Eastern Utah. The cactus is found in a landscape highly disturbed by non-renewable energy production. To understand the environmental conditions that support natural growth of this cactus, we asked what types of plants were present in the same areas as the cactus, and if the types of plants were different in environments that were disturbed. From our assessment, we determined that the types of plants present in disturbed areas were drastically different from those present in undisturbed locations. Areas previously used for energy production are …

Increasing Knowledge And Detection Of Racial And Ethnic Microaggressions In White College Students, Christina A. Patterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Scholars have strongly suggested that to combat microaggressions and their impact on persons of color, there needs to be an increased awareness and ability to detect microaggressions when they occur. There is limited research on how to practically address these concerns. This study examined the efficacy of a multimedia intervention aimed at increasing White individuals’ ability to accurately detect microaggressions. The high-exposure intervention was compared against two other conditions, low-exposure and control, at pre-, post-, and 1-week follow-up from intervention.

Undergraduate university students were recruited from two predominantly white universities (PWU). Participants watched a series of videos to determine if …

Direct And Indirect Effects Of Climate Change On Plant Populations And Communities In Sagebrush Steppe, Andrew R. Kleinhesselink

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rapid climate change presents humanity with a number of big problems. Foremost among these is the sad fact that the climate we will pass on to our children will likely be nothing like the climate that we inherited from our parents. Ecologists have collected solid evidence that climate change has already begun to affect the living things around us and the ecosystems humans depend on. Unfortunately, predicting the future effects of climate change on life on earth is not easy. We focused on three research goals as part of an effort to improve our ability to predict how plants and …
