Grassland Productivity And Water Quality: A 21st Century Issue, David M. Nash, P. M. Haygarth

IGC Proceedings (1977-2023)

1. Irrigation and other changes to the hydrological cycle can increase soil and water salinity.
2. Primary salinisation is a natural process that affects much of Europe, Asia, Africa, the Americas and Australia. Secondary salinisation is caused by human activities such as irrigation and land clearing that mobilise salt stored in the soil.
3. The critical water contaminants exported from grasslands are nitrogen, phosphorus, potential pathogens and sediment.
4. The mechanisms responsible for diffuse pollution from grasslands and mitigation strategies are most effectively investigated using a ‘source-mobilisation-transport’ framework.
5. There is a lack of coherent interaction across discipline boundaries that links pollutant sources to impact. …

Adoption Of Tropical Legume Technology Around The World: Analysis Of Success, H. M. Shelton, Steven Franzel, M. Peters

IGC Proceedings (1977-2023)

Grassland In Ireland And The Uk, Myles Rath, S. Peel

IGC Proceedings (1977-2023)

1. Grassland is the dominant land use option in Ireland and the UK, and is characterised by a long growing season.
2. Dynamic, interactive systems of grassland management have been developed which combine high grass dry matter intakes with good sward quality. In the better grassland areas milk yields in excess of 7000 kg/cow are attainable with low levels of concentrate supplementation. In the times to come, measures to protect the environment will constrain stocking rates, and fertiliser and manure use on intensive grassland enterprises.
3. A high proportion of beef and sheep farms participate in voluntary, EU-funded agri- environmental schemes that promote …

Reconnaissance Of Landslides And Debris Flows Associated With The July 2022 Flooding In Eastern Kentucky, Matt M. Crawford, Zhenming Wang, Seth Carpenter, Jonathan Schmidt, Hudson J. Koch, Jason M. Dortch

Report of Investigations--KGS

Between July 25 and July 30, 2022, a series of convective storms generated approximately 14–16 inches of rainfall across parts of eastern Kentucky, predominately in Clay, Leslie, Perry, Breathitt, Knott, and Letcher Counties. The peak rainfall occurred on the evening of July 27 and the morning of July 28, with the hardest-hit areas experiencing more than 10 inches in a 24-hour period. The historic rainfall led to catastrophic flooding along many rivers and streams, but also triggered widespread landslides and debris flows that damaged roads, homes, property, and other infrastructure. Once initial relief and recovery efforts were established, the Kentucky …

High Volume Multiplex Staining Of Mouse Model In Alzheimer’S Associated Disease Pathology, Chloe Embry

Lewis Honors College Thesis Collection

Although neurodegenerative diseases are often clinically distinct, they typically share common pathological markers. One of the most common causes of clinical dementia is Alzheimer’s disease (AD). Pathologically, AD is defined by the presence of intercellular tangles composed of hyperphosphorylated tau proteins and extracellular plaques made of abnormally cleaved amyloid-beta proteins. However recent genome-wide association studies have also found that many of the predispositions for AD are located on or near genes highly expressed in microglia. In the healthy CNS, microglia act as the brain’s immune system and are chiefly involved in neuronal support and maintaining homeostasis throughout the CNS. Typically, …

Community Supported Agriculture Values: A Comparison Across Groups, Thomas B. Pierce

Theses and Dissertations--Agricultural Economics

Community Supported Agriculture (CSA) programs offer consumers the chance to share the risk with farming operations while gaining access to fresh, local foods. While research on CSA shareholder values such as share affordability or the local impact of participation has been conducted in the past decade and beyond, less attention has been paid to direct value-mapping of the shareholders themselves. This research seeks to determine consumer values around the CSA purchasing decision using the Best-Worst Scaling Approach. Based on a focus group discussion with CSA shareholders in a university wellness voucher program, we used affinity diagramming to develop a list …

Exploring The Therapy Experiences Of Latinx Individuals Working With Non-Latinx Therapists, Edith Del Moral

Theses and Dissertations--Family Sciences

Latinos are the largest minoritized ethnic group in the United States. Despite having a population of 62.1 million Latinos in the United States, the representation of Latinx therapists remains low. Therefore, the chance for Latinx individuals and families to receive mental health services from a Latinx therapist is very low. This phenomenological study examines the experiences of six Latinx individuals who worked with non-Latinx therapists. The resulting themes included therapist client match, awareness, respect for boundaries, and genuineness. These themes informed by the personal stories of people who have gone through the therapeutic process will aid professionals in the field …

Ideal Body Weight And Body Fat Percentage Predict Relative Energy Deficiency In Sport (Red-S) Scores In Collegiate Athletes, Emily Norman

¿El Papel Lo Aguanta Todo? Linguistic Nationalism In Hispanic Constitutions, Mihir Kale

Gaines Fellow Senior Theses

Linguistic nationalism is among the most well-documented sections of nationalist study, as it is one of the predominant mechanisms in which nationalist sentiments are codified or enforced within a state. Cultural or ethnic nationalist preferences are typically expressed through the imposition and preference of a certain nation’s language to demonstrate power, and examples of linguistic nationalism have been recorded across all continents and societies throughout history.

The Primacy Of Openness In Ecological Complexity Theory, Colby Clark

Theses and Dissertations--Philosophy

Five principles are at the foundation of complex systems theory: emergence, openness, contingency, historicity, and indeterminacy. Of those five, the principle of emergence is easily the most prevalent. Simply put, emergence refers to the idea that some wholes cannot be properly accounted for by appealing to individual explanations of the parts that compose it. In ecological complexity theory, the principle of emergence is strongly associated with the self-organizing feedbacks that often identify the structural framework of ecosystems.

Within the last half century, the intense focus on the principle of emergence has engendered the development of many conceptual distinctions that have …

Effects Of Elevated Extracellular Dopamine On Astrocytes In The Nucleus Accumbens, Mengfan Xia

Theses and Dissertations--Pharmacology and Nutritional Sciences

Nucleus accumbens is involved in processing of motivational and affective behaviors and plays a significant role in development and maintenance of substance use. Released from the ventral tegmental area into the nucleus accumbens, the mesolimbic dopamine controls incentive salience and facilitates learning of reinforcement and reward-related motor functions. Recent studies reveal that, in the context of cocaine exposure, dopamine transmission in the ventromedial striatum is pivotal to the regulation of initial drug use. Astrocytes, a major subpopulation of the brain glial cells, are an active component of the so-called tripartite synapse and communicate with neurons through the release of transmitters …

"It's All Lateral Violence": How Sexual Minority Men Cope With Appearance Discrimination, Matthew T. Richardson

Theses and Dissertations--Educational, School, and Counseling Psychology

Sexual minority men experience higher rates of body dissatisfaction (BD) than heterosexual men (Frederick & Essayli, 2016). BD is associated with negative health outcomes in this population, including eating disorders (Yean et al., 2013), depression (Blashill et al., 2016), suicidality (Grunewald, Calzo, et al., 2021), and risky sexual behavior (Goedel et al., 2017). Sexual minority men who use dating apps may be at greater risk of experiencing BD via exposure to appearance-based discrimination (Tran et al., 2020), sexual objectification, and weight stigma (Filice et al., 2019). Little is known about sexual minority men’s experiences of appearance discrimination on dating apps …

The Effect Of Exceptionality Label On School Psychologists During The Evaluation Process, Rachel Jacob

Theses and Dissertations--Educational, School, and Counseling Psychology

School psychologists often lead the evaluation process that is responsible for identifying students with an education-based disability. They are also responsible for providing recommendations for the student following the evaluation. The current study is focusing on the variable of exceptionality label as it is a universally present variable that has the potential to affect all evaluations. Two recent studies have examined and found labeling bias on preservice educators (Allday et al., 2011; Fisher et al., 2022). This study sought to expand this research by looking at labeling bias in school psychologists. The study measured the effect of exceptionality label on …

An Examination Of Factors Impacting Home-School Collaboration In Head Start Populations, Madison Mei-Mei Yee

Theses and Dissertations--Educational, School, and Counseling Psychology

Two essential pillars in a preschool-age student’s life include their caregiver and their teacher. In turn, it is unsurprising that a more cohesive relationship between these two figures can promote better wellbeing, academic skills, and overall developmental growth in young children. Unfortunately, a multitude of barriers impede home-school collaboration, such as socioeconomic status, non-English speaking households, and caregiver mental health, just to name a few. Head Start, a federally funded preschool program, targets underserved populations who often relate to these named barriers. Head Start works out of the Parent, Family, and Community Engagement (PFCE) Framework, a framework specifically geared toward …

Disparities In Mental Health Technology Among African Americans: Breaking Cultural Inclusion Barriers, Nyoki Cosey-Brown

DSW Capstone Projects

Mental health technology is a healthcare delivery model of the future. The engagement in virtual healthcare was intensified when traditional healthcare methods were inaccessible during the federal restrictions implemented due to the COVID-19 pandemic. Utilizing digital apparatuses for healthcare improved the convenience, efficiency, and accessibility of various mental health services that were inoperable in past healthcare models. However, the historical constructs of stigma, discrimination, inequity, exclusion, and structural racism in mental healthcare were prevalent problems that remained present in virtual mental health platforms concerning the experiences of African-American patients and professionals who utilized the spaces.

This research explored mental health …

Cyborgs, Dolls And Passing Narratives: Trans-Femininity In Popular Music, Quinn J. Troia

Lewis Honors College Thesis Collection

The Cyborg is a figure that has been used by feminist scholars as a metaphor for feminist issues and transgender identity because the embodiment of both transgender people and cyborgs challenges binary understandings of male/femaleness and human/nonhumanness respectively. This comparison has also suggested the potential of reading cyborgs as passing figures who attempt to perform normative social identities; however, scholarship analyzing Cyborg figures has not explored this in ways that are specific to trans-feminine people. By combining contributions from the theory of gender performativity and research on transgender linguistic practices and identity construction, I perform a visual and textual analysis …
