Understanding Potential Profitability Estimates for Western Kentucky Grain Production
No full textThe objective of this project is to develop a model to predict profitability within the Western Kentucky grain markets, with a particular focus on corn and soybeans. The research was conducted utilizing historical data on production budgets, yields, and market prices spanning from 2007 to 2021. Through the course of this study, a series of simulations were conducted, which generated a broad range of potential profit outcomes. These profit ranges were subsequently converted into Probability Distribution Functions, offering a spectrum of probabilities ranging from 0% to 100%. The resulting outcomes , along with the supplementary simulation data, have the potential to serve as valuable tools for grain producers, helping them navigate external factors that may influence profitability during any given growing season
Comparing the hydrology of newly established and remnant wetlands over time
No full textThe Wetland Reserve Program (WRP) was developed by the National Resources Conservation Service (NRCS) of the USDA to reverse the conversion of wetlands to cropland that has occurred in the past two centuries. The importance of wetlands is something that is more understood in recent years, inspiring the efforts to restore and protect wetlands that were previously destroyed. Landowners can participate in the WRP to allow those wetlands to be restored and provide the ecosystem services that they once offered. These pieces of land can then be studied to investigate the functioning of these restored wetlands. Monitoring two WRP sites along the Obion Creek and two along the Bayou de Chien in Western Kentucky, we studied how hydrology differs in remnant bottomland forests compared to newly established forests. Remnant areas are those that contain secondary forests while newly established areas contain younger tree plantings (within the last 10 years). Hydrology is an important aspect of wetlands and can alter the biotic communities present and how the wetland functions. We examined water level data from four different WRP sites and calculated hydrologic metrics including median water level, mean monthly water level, stage duration, return time, hydrologic flashiness, and stage excursion frequency. We found that there was a statistically significant difference in the hydrology between the remnant and newly established forests at all four sites. There was also a significant difference in the hydrology at each site based on the time of year the sample was taken. This indicates that hydrology differs between remnant and newly established forests, creating a variable environment within restored wetlands. It also shows that hydrology changes seasonally in the restored wetlands
The Price of Applause: Analyzing the Impact of Tony Awards on Broadway Show Revenue
No full textThis project evaluates the potential difference in weekly gross revenue between shows that won a Tony Award – the theatre industry’s most prestigious honor – and shows that were nominated for a Tony Award but did not win. This research has the potential to offer analysis of if winning a Tony Award tends to indicate more revenue and also some insight into the elasticity of the Broadway show market
Effects of Cabin1 loss-of-function in nervous system development
No full textUnchecked overproduction of cerebellar cells can lead to medulloblastoma, the most common pediatric brain tumor. Cerebellar granule cells are normally overproduced and pruned into adulthood under the regulation of the transcription factors MADS/myocyte-enhancer-factor 2 (MEF2) and p53. MEF2 and p53 have opposing effects on healthy granule cell populations: MEF2 promotes cell survival and p53 promotes apoptosis. In medulloblastoma, the reverse appears: abnormal p53 activity is associated with tumor proliferation and impaired MEF2 regulation promotes apoptosis of tumor cells, while most other genetic determinants are unknown. Both MEF2 and p53 are regulated by calcineurin-binding-protein 1 (Cabin1). A major obstacle in understanding the roles of Cabin1 in normal cerebellar development and tumorigenesis lies in reconciling that Cabin1 appears to play opposing roles targeting MEF2 and p53 in normal versus diseased cells. Determining where and when Cabin1 is expressed during normal development and understanding its roles therein will provide clarification. Our central hypothesis is that Cabin1 functions in the cerebellum as a negative regulator of MEF2 and p53 to ensure appropriate numbers of granule cells are generated and maintained. We are using behavioral tests to assess the effects on organismal function in Cabin1 loss-of-function mutants. We conclude that loss-of Cabin1 impairs certain behaviors
Snake-Handling in American South
No full textSnake-handling traditions have often been considered absurd or uncivilized due to the stereotypes that not only come from extreme religion, but from the secluded environment of the practitioners in the Appalachian mountains. When looking deeper into the tradition of snake-handling, there is much to uncover when it comes to the church environment and the role of women within these church hierarchies. Researching first-hand accounts of believers allows deep insight to the workings of the church and what these believers account for. Looking at outsiders’ accounts of the faith, yet accepted into their church, allows an outside and objective look at their faith and how they celebrate it. By researching this stereotyped religion, it allows readers to understand that despite its villainization through media and being misunderstood, this religion retains respect from its members, despite the ‘othering’ of its female members
Influence of Psychotropic Drugs on Developmental Gene Expression in Zebrafish
No full textRecent studies have provided evidence of the relationship between environmental factors and susceptibility to neurodevelopmental disorders. Some findings suggest that long-lasting disruptions in the structure and function of the nervous system are frequently caused by prenatal exposure to drugs of abuse. The inappropriate use of both legal and illegal drugs has long been a major issue in the United States. A substantial amount of prescribed and illicit psychotropic drugs is excreted through urine and feces every day. Wastewater treatment does not effectively remove drug residues, resulting in contaminated water being discharged into surface water sources, which ultimately reaches the drinking water that is consumed by humans and animals. Although the drug levels detected in source water bodies are low, the real impact of the mixture of these low drug doses on the nervous system remains unknown. Zebrafish (Danio rerio) are used as a toxicity model due to their significant neurological resemblance to humans. Our central hypothesis is that developmental exposure to low levels of psychoactive drugs through contaminated water will significantly affect protein and gene expression involved in the development and function of the nervous system

Abstract:
This study compares the influence of legume and non-legume crops on soil properties for a better understanding of the roles that crops play in maintaining soil health and sustainability. The ability of leguminous crops to take nitrogen out of the air and store it in the soil-in the case of soybean, for instance-naturally enriches the soil. This attribute of legumes reduces the use of external nitrogen fertilizers and, consequently, enhances the fertility of the soil by replenishing the key nutrients naturally. Other crops, such as maize, do not have this attribute and hence must be supported with nitrogen application through fertilizers. This is perhaps a very critical difference in methods of nutrient inputting that may have consequences for the quality and health of the soil and for sustainable agriculture in the long term.
For this reason, field soil samples from legumes and non-legumes were collected for analysis, considering some of the key properties of soil including SOM, pH, bulk density, porosity, and water-holding capacity of soil. In this case, SOM has been considered one of the most critical properties responsible for soil fertility. On the other side, bulk density and porosity are the properties of soil that directly influence the root growth, water retention, and aeration in the soil. Thus, soil pH affects nutrient availability, and water-holding capacity is one of the important factors for drought tolerance. In addition, some plots of legume and non-legume species were compared to investigate crops that would be selected based on physical properties of soil. It is expected that the investigation of these variables will show how, on one side, legume crops can improve the quality of the soil over time and, on the other, reduce dependency on chemical fertilizers toward more viable and sustainable agriculture. This work may give insight that could allow farmers and land managers to give useful recommendations on how to enhance soil fertility and maintain healthy and productive soils within the context of sustainable agriculture. The present work underlined the basic role crop diversity plays over farming practices, or more precisely legume strategic deployment, in building more fertile and resilient soils.

Implementing Stress Reduction Strategies in New Graduate Nurses
No full textNew graduate nurses (NGN’s) experience significant stress as they transition into their roles, particularly in the Emergency Department, due to high responsibilities, staffing issues, and demanding environments. Stress, along with factors like poor leadership and high nurse-to-patient ratios, contributes to burnout and increased turnover. This DNP project aimed to evaluate the effectiveness of stress management interventions during NGN orientation in the emergency department. A pre- and post-intervention survey using the Nurse Stress Index (NSI) measured stress levels before and after the orientation period. The NSI survey was completed at the beginning of the program to establish baseline stress levels, and after the orientation period to assess any changes in stress following an intervention. NGNs were encouraged to implement stress management strategies throughout their orientation. Results from both pre- and post-intervention surveys showed stress levels ranging from “very little pressure” to “moderate pressure,” using a 5-point Likert scale. The pre-intervention mean score was 2.15, while the post- intervention mean was 2.38, indicating a slight increase in stress levels by the end of orientation. Most participants reported using the stress management interventions 4-6 times during orientation. These findings suggest that while stress management interventions may be beneficial, they did not lead to a reduction in stress during orientation. Future interventions may need to be adjusted to more effectively decrease stress levels. Further research is needed to explore alternative strategies to support NGN’s and enhance the impact of stress reduction efforts.
