The twenty-question survey inquired about demographic information, medical history, and the timing and perceived comprehension of education received. The researcher discovered that the majority of patients did not receive education that identified hypertension and diabetes as contributing factors of kidney disease until after diagnosis of kidney disease. The vast majority of participants reported that education regarding the life implications of dialysis, including fluid and dietary restrictions, …

Translational Approaches To Understanding Resilience To Alzheimer's Disease., Sarah M Neuner, Maria Telpoukhovskaia, Vilas Menon, Kristen M S O'Connell, Timothy J Hohman, Catherine Kaczorowski

Faculty Research 2022

Individuals who maintain cognitive function despite high levels of Alzheimer's disease (AD)-associated pathology are said to be 'resilient' to AD. Identifying mechanisms underlying resilience represents an exciting therapeutic opportunity. Human studies have identified a number of molecular and genetic factors associated with resilience, but the complexity of these cohorts prohibits a complete understanding of which factors are causal or simply correlated with resilience. Genetically and phenotypically diverse mouse models of AD provide new and translationally relevant opportunities to identify and prioritize new resilience mechanisms for further cross-species investigation. This review will discuss insights into resilience gained from both human and …

Are Some Analysts Superior At Forecasting World Grain Supplies?, Emmie M. Noyes

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Whether agriculture is how you make your living or simply a means of putting food on your table, the prices of agricultural commodities and products affect us all. When buying and selling agricultural commodities, both farmers and firms use futures markets. Futures markets help minimize price risk, which is important to both sides of the transaction.

Recently, private analysis firms have started to forecast the information contained in the USDA’s WASDE report. This is relevant because future prices react to new information contained in WASDE reports. These firms will release their information a few days before the WASDE comes out …

A Comprehensive Bison Management And Research Plan For The Crane Trust, Joshua D. Wiese

Other Publications in Wildlife Management

The Great Plains were once a vast grassland ecosystem, but, due to agricultural and human development, are one of the most endangered ecosystems in North America. What remains is generally fragmented, threatened by invasive species, and lacks the natural ecosystem processes that shaped these grasslands such as periodic wildfire and bison grazing. Since 1978, the Platte River Whooping Crane Maintenance Trust, Inc. (dba “Crane Trust”) has worked to maintain the function of grassland and riparian habitats to benefit endangered Whooping Cranes, Sandhill Cranes, and other migratory bird species. They protect ~8,100 acres, including the largest contiguous portion of lowland tallgrass …

Identification Of Translesion Synthesis Inhibitors That Target Rev7/Rev3 Protein-Protein Interactions, Seema Patel

University Scholar Projects

Translesion synthesis (TLS) is a cellular mechanism utilized by cancer cells to tolerate DNA damage caused by chemotherapeutics, like cisplatin, by replicating past unrepaired lesions. This increases the rate of mutations, which leads to the emergence of drug-resistant cancer cells. Preliminary studies have shown that disrupting the protein-protein interactions (PPI) in the TLS heteroprotein complex increases cells’ sensitivity to first-line genotoxic chemotherapy, illustrating how inhibiting TLS assembly and function can significantly increase cancer cell death. These results underscore the therapeutic potential of targeting TLS PPI. My thesis focuses on identifying inhibitors capable of disrupting the Rev7/Rev3 TLS PPI. This study …

Fate Of Listeria Monocytogenes On Two Salad Blends At Ideal And Abusive Temperatures, Taran Virdi

Master's Theses

The consumption of ready-to-eat (RTE) foods has increased with popular RTE salad blends including non-traditional ingredients such as shredded Brussels sprouts, kale, red and green cabbage, chicory, and broccoli stalk. Concurrently, there has been an increase in the number of foodborne illnesses and outbreaks associated with leafy greens. The potential risk associated with these ingredients must be addressed as they have not typically been consumed raw, especially since L. monocytogenes continues to be a leading cause of foodborne illnesses and outbreaks. This study evaluated the survival of L. monocytogenes on two RTE salad blends at refrigeration, mildly abusive, and abusive …

Effects Of Sunrise/Sunset Lighting On Corticosterone Levels In Coturnix Quail (Coturnix Coturnix), Hannah Feuerborn

Poultry Science Undergraduate Honors Theses

Both genetics and environment play an important role in the growth, performance and overall welfare of poultry species. Current commercial production practices typically do not mimic the natural environmental conditions of ancestral poultry species, specifically lighting requirements. In nature, poultry species are subjected to natural day length and the slow rising and setting of the sun. This is compared to commercial conditions in which lights are sudden on/off, not mimicking the natural trajectory of the sun in terms of light intensity and exposure. The current study aimed to evaluate the impact of genetics and the effect of sunrise/sunset lighting on …

Factors Affecting Graduation With Honors: A Case Study In Business, William Litzinger

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Many first-year college students elect to enroll in their university’s honors program. These programs offer students many educational benefits not provided to non-honors students, such as smaller class sizes, priority registration, and added faculty interaction. However, of the students that enter the university as an honors student, many fail to complete their honors program. Researchers have documented completion rates as low as 18.45% (Campbell and Fuqua, 2008). So why are honors graduation rates so low? In this study, variables were examined that the literature suggests affects honors graduation rates (High School GPA, ACT/SAT scores, AP credits, GPA 1^st term …

Carnarvon Floodplain Management - Working Group Report, Department Of Primary Industries And Regional Development, Western Australia, Department Of Water And Environmental Regulation, Western Australia, Canarvon Growers Association, Department Of Fire And Emergency Services, Western Australia, Shire Of Canarvon, Western Australia

Horticulture research reports

Periodic flooding of the lower Gascoyne River floodplain at Carnarvon is a natural event. The flooding results from cyclonic and thunderstorm activity in the catchment, with the risk period generally from November to May, associated with the wet season in the north of WA. The Carnarvon horticultural area has suffered considerable damage following flooding of the Gascoyne River in 1960,1961, 1974, 1980, 1995, 2000, 2009, 2010/11 and 2021.

The WA Government has undertaken restoration programs to replace soil lost for most of these major flooding events. Apart from the soil loss and risks of permanent damage to the natural resource, …

Ongoing Calculus In The Cerebral Cortex, Luke Long

Physics Undergraduate Honors Theses

Various modes of neuronal computations have long been theorized to be possible based on the structure and geometry of the brain. These computations also seem necessary for many of the integral functions of the brain, like information processing and regulatory processes in the body. However, experimental data directly supporting these claims have been rare.

In this study, data collected in mice from a large number of neurons over a long period of time provided the opportunity to search for some of these computations, specifically change detection and squaring calculations. Using Matlab, the goal of this analysis was to find statistically …

Scale-Free Behavioral Dynamics Directly Linked With Scale-Free Cortical Dynamics, Sabrina Jones

Physics Undergraduate Honors Theses

In organisms, an interesting phenomenon occurs in both behavior and neuronal activity: organization with fractal, scale-free fluctuations over multiple spatiotemporal orders of magnitude (1,2). In regard to behavior, this sort of complex structure-- which manifests itself from small scale fidgeting to purposeful, full body movements-- may support goals such as foraging (3-6), visual search (4), and decision making (7,8). Likewise, the presence of this sort of structure in the cerebral cortex in the form of spatiotemporal cascades, coined “neuronal avalanches,” may offer optimal information transfer (9). Thus, when considering the functional relationship between the cerebral cortex and movements of the …

Food Allergy Education In The Hospitality Industry, Hayley Stull

Human Nutrition and Hospitality Management Undergraduate Honors Theses

Food allergies affect thousands of people, because hospitality foodservice workers come into contact with the public, it is necessary that they need to be fully trained to ensure the safety of the public. This is especially important for those who possess food allergies. Previous research has shown major gaps in knowledge amongst these workers, which can lead to the potential to harm individuals with a food allergy. There is a lack in the consistency of training specifically concerning food allergies for food service workers across all states in the U.S. There are previous forms of educational tools concerning food allergies …

Camp: Children’S Acceptance Of Muffins With Different Proteins, Amber Knoernschild

Human Nutrition and Hospitality Management Undergraduate Honors Theses

In 2019, around 40% of school-aged children in Arkansas were classified as overweight (~17%) and obese (~23%), according to BMI data collected. Children with obesity have an increased risk of developing type 2 diabetes, hypertension, and dyslipidemia. Unhealthy eating habits, such as skipping breakfast, have been strongly associated with overeating, weight gain and obesity. Breakfast is a key component of a healthy diet and can positively impact children’s health and well-being. However, there has been a steady decline in breakfast consumption in US children over the past 40 years. Specifically, breakfast consumption declined among 8–10-yearold children by 9% and adolescents …

Effects Of Glucocorticoids Upon Pro-Inflammatory Responses To Acute Sleep Fragmentation, Hunter Weaver

Masters Theses & Specialist Projects

Sleep loss is a common problem in humans who suffer from obstructive sleep apnea. Sleep aids in the regulation of immune responses, some of which induce inflammatory responses. Cytokines regulate the inflammatory process and are released in response to sleep fragmentation (SF) in mice. Glucocorticoids are hormones that are released from the adrenal cortices during a stress response and are considered to be anti-inflammatory and immunosuppressive at high doses but may stimulate immune function on an acute level. The first hypothesis tested was that normal physiological expression of glucocorticoids (Sham) will display increased IL-1β and TNFα expression levels, while high …

Towards The Determination Of Estrone And 17Β-Estradiol In Dairy Cattle Waste Using Solid Phase And Stir Bar Sorptive Extractions With Liquid Chromatography-Mass Spectrometry And Gas Chromatography-Mass Spectrometry, Pallavi Ragi

Masters Theses & Specialist Projects

Steroidal hormones are naturally produced as a part of many physiological processes and are excreted in the urine and feces of animals and humans. Farm animals in concentrated animal feeding operations (CAFOs) are routinely implanted with synthetic and natural hormones to enhance growth and production, contributing significantly to environmental steroid hormone contamination. Every year around 49 tons of estrogens are generated by livestock waste in the United States alone. Due to rainfall and runoff, these steroid hormones reach the environment when animal waste is applied as manure. Studies show that estrogens and other steroidal hormones present in the surface waters …

Agriculture Education Teacher Perspectives On Stem In Secondary Classrooms -A Delphi Study, Nicholas Kyle Porter

Masters Theses & Specialist Projects

Recent statistics tell us that the number of jobs in Science, Technology, Engineering and Mathematics (STEM) related fields are growing at a rapid rate, it is projected that STEM related careers will grow 17% between 2008 and 2018 (Langdon, n.d.). Within these areas lies agriculture. Given the shift of career opportunities, such as in the areas of research and development, a change has to be made in the way students are educated within agriculture. The ultimate goal of all educators is to better prepare students for their future careers and endeavors because these students are the future of our food …

Factors Influencing Tree Growth In A Bottomland Hardwood Along The Green River In Kentucky, Caleb Miller

Masters Theses & Specialist Projects

In bottomland hardwood forests, large fluctuations in moisture availability can lead to stress from both flooded and drought conditions. These forests can have a complex species composition with different water use and drought strategies. The bottomlands in which these species co-occur can have a complex spatial distribution of alluvial sediments due to the meandering and migration of river or stream channels, which may impact the hydrology, nutrient dynamics, and productivity. At Western Kentucky University's Green River Preserve, approximately 9 ha of bottomland hardwood forest were planted in 2006. Although these hardwoods have received equal amounts of sunlight, rainfall, and wind, …

Impact Of A Cattle Crossing On Water Quality Along A Tributary Of The Muddy Fork Of The Illinois River, Northwest Arkansas, Nicholas Valentini

Animal Science Undergraduate Honors Theses

Cattle are known to have an effect on water quality in various bodies of water. Studying how cattle impact water quality along various streams and tributaries is important to understanding how certain water parameters may be affected at the individual farm level. It is known that unrestricted access to a cattle crossing has been shown to increase the occurrence of downstream pollutants such as E. coli, ammonium, total kjeldahl nitrogen, total suspended solids, total phosphorus, and turbidity. However, many studies focus on large-scale operations and neglect the individual farm level. In this study, samples were collected twice for each …

Pandemics And Animal Welfare: How The Covid-19 Pandemic Has Affected The Companion Animal Industry In Northwest Arkansas, Sabrina Cox

Animal Science Undergraduate Honors Theses

The first cases of coronavirus reported in the United States came in January 2020 (World Health Organization, 2020). In the two years since then, countries around the world have been affected by COVID-19 and the subsequent social, economic, and mental health issues. Previous research shows that the animal healthcare field is already overrun with burnout, substance abuse, depression, and increased levels of stress (Gardner & Hini, 2006), and the pandemic has only compounded these issues (Mair et al., 2020). Observing a lack of meaningful reporting on the issues affecting veterinary staff led the researchers to investigate staff members’ practices, day- …

Rodent Dental Microwear Texture Analysis As A Proxy For Fine-Scale Paleoenvironment Reconstruction, Jenny H. E. Burgman

Graduate Theses and Dissertations

Dental microwear texture analysis (DMTA) of fossil fauna has become a valuable tool for dietary inference and paleoenvironment reconstruction. Most of this work has utilized larger taxa with larger home ranges. These studies may result in broader-scale habitat inferences that could mask the details of complex mosaic habitats. Rodent DMTA offers an opportunity to work at finer spatial scales because most species have smaller home ranges. Rodents are also keystone species within their ecosystems, abundant, ubiquitous, and found in many fossil deposits. These attributes make them excellent proxies for environmental reconstructions. However, the application of DMTA to rodents remains relatively …
