Assessing Invasive Plant Species In Louisville’S Urban Forest, Elizabeth Winlock

Cities and the Environment (CATE)

Within Louisville, KY’s network of urban green space and forests, invasive plant management is vital to protecting biodiversity and allowing native species to thrive. Partners across the city have been working to identify non-native invasive species, map their spread, monitor how they affect native species, and mitigate damage from invasive plants. Much of that falls into three categories:

1) Mapping patterns of invasive plant presence in relation to disturbance

2) Recording the effects of various management practices and

3) Tracking forest health through the regeneration of native tree seedlings and saplings

This data is used to inform management plans and …

Non-Music Major Participation In Collegiate Marching Bands: A Necessary Demographic Required For The Survival Of The Collegiate Marching Band, Alexander Scott Kirby

Doctoral Dissertations and Projects

The collegiate marching band can be the face of a university and the heartbeat of campus. Marching bands attract students from all majors across the campus, where those who major in music have the opportunity to be the smallest demographic in the ensemble if the ensemble is open to the entire college or university. Without non-music majors’ participation in collegiate marching bands, programs would not thrive as they do today. Numerous researchers have discovered that many students who had joined an ensemble did not participate in a collegiate performing ensemble after high school graduation. In particular, Mantie and Dorfman described …

Sartorial Representations Of Trans Men In The Post-Frontier West: A Case Study In Gender, Class, And Concepts Of Societal Degeneration, Rose Caughie

University Honors Theses

Clothing is communication. How it is perceived reveals a society's values and anxieties. In the post-frontier American west, moralistic laws against cross-dressing combined with fears of societal degeneration, resulting in the formation and enforcement of normative visions of gendered dress. When trans men Harry Allen and Milton Matson were arrested, images of them were published in newspapers across the nation. Allen's working class wear and close criminal contact with racial minorities reflects one perceived source of degeneration while Matson's high class look and British immigrant status reflects the other. This essay will consider how these men's clothing and bodies were …

Relationship Between Social Support And Stress In Accelerated Nursing Students, Karen L. Bravo

Dissertations

Nursing program attrition rates and retention rates in the first year of professional practice are excessive due to stress. Investigating through this quantitative, correlative research study is due to the lack of information related to accelerated students and stress. Theories framing this study, the Transactional Model of Stress and Coping, and Triadic Reciprocal Determinism Theory, posit that the environment, whether internal or external, affects stress reactions. The research questions included relationships of Significant Other Support, Family Support, and Friend Support to Perceived Stress Score in a two-part online survey of 116 United States participants.

Civil and Environmental Engineering Faculty Publications

Grease, oil, hydrocarbon residues, heavy metals, and surfactants are all present in car wash wastewater (CWW), which all can have detrimental effects on the environment and human health. This study was designed to assess CWW treatment using an upgraded physical technique combined with a range of conventional and more sustainable coagulants. Physical treatment effectively lowered the oil and grease (O&G) and chemical oxygen demand (COD) of the CWW by 79 ± 15% and 97 ± 1.6%, respectively. Additional treatment was provided using chemical coagulation–flocculation– settling. In jar test studies, humic acid (HA) and alum were found to provide significantly higher …

Model-Assisted Online Optimization Of Gain-Scheduled Pid Control Using Nsga-Ii Iterative Genetic Algorithm, Shen Qu, Tianyi He, Guoming Zhu

Mechanical and Aerospace Engineering Faculty Publications

In the practical control of nonlinear valve systems, PID control, as a model-free method, continues to play a crucial role thanks to its simple structure and performance-oriented tuning process. To improve the control performance, advanced gain-scheduling methods are used to schedule the PID control gains based on the operating conditions and/or tracking error. However, determining the scheduled gain is a major challenge, as PID control gains need to be determined at each operating condition. In this paper, a model-assisted online optimization method is proposed based on the modified Non-Dominated Sorting Genetic Algorithms-II (NSGA-II) to obtain the optimal gain-scheduled PID controller. …

Celebrity Affect, Social Media Fandom, And Parasocial Interactions: A Thematic Analysis Of Fan Reactions To Kris Wu’S Sexual Scandals In China, Yan Zhao

Communication ETDs

In this thesis, the rise and fall of a popular Chinese celebrity, Kris Wu, provided the context to examine fans’ negotiation of parasocial and affective relationships in online interactions with the celebrity and other fans. On the basis of a thematic analysis of Chinese fans’ comments on social media before and after Wu’s arrest and conviction for rape and other sexual crimes in 2022, I highlight the fluidity of fans’ positive and negative parasocial interactions and emotional attachments to a celebrity. The analysis suggests how fans can prioritize their continued support and admiration for a celebrity above matters of morality …

Pathology Research and Scholarship

Electronic cigarette (Ecig) use has become more common, gaining increasing acceptance as a safer alternative to tobacco smoking. However, the 2019 outbreak of Ecig and Vaping-Associated Lung Injury (EVALI) alerted the community to the potential for incorporation of deleterious ingredients such as vitamin E acetate into products without adequate safety testing. Understanding Ecig induced molecular changes in the lung and systemically can provide a path to safety assessment and protect consumers from unsafe formulations. While vitamin E acetate has been largely removed from commercial and illicit products, many Ecig products contain additives that remain largely uncharacterized. In this study, we …

The Intellectual And Diplomatic Discourse Of American Progressives And The Late Ottomans, 1830–1930, Brigitte Maricich Powell

Doctoral Dissertations and Projects

The American intellectual and diplomatic discourse with the late Ottoman Empire is an understudied field of history. Major works to date are primarily focused on the US relations with the Turkish Republic starting in 1924, which at best may highlight the Barbary Wars and the Treaties of 1830 and 1862 as a precursor. Few works offer, if any, a comprehensive insight into the diplomatic relationship that evolved between the US and the Near East from 1830 to 1930. This research is meant to fill the absence by probing into the service of key American diplomats and intellectuals who visited and …

Enhancing Culturally Responsive Practices: A Phenomenological Study On How Elementary School Leaders Demonstrate Cultural Proficiency In Teacher Development, Dana Synora Jones

The Historical And Modern Significance Of The Choctaw Hymnody, Angela M. Boatner

Doctoral Dissertations and Projects

Working with the Native Choctaw populations of early America, missionaries did much in the way of music and composition. One result was a compilation of original hymns written by English missionaries in the native Choctaw tongue, but there were also Choctaw composers and contributions. Singing these hymns in church services, gatherings, and social situations remains an activity where the Oklahoma and Mississippi tribal members participate today. The recorded history of the known hymns and composers is scarce and is disappearing daily in favor of teaching the ancient cultures rather than the religion of the white colonists. The research chose a …

Restoration Of Key Middle Age Demographic Can Save The African Methodist Episcopal Church, Geromy D. Johnson

Doctoral Dissertations and Projects

St. Luke faced years of struggles resulting in a dwindling ministry and membership with specific impacts resulting in missing generations within the church. The missing generations include Generation X who were born between 1965-1980, Generation Y who were born between 1981-1996, and generation Z who were born between 1997-2012. There are many methods used to combat church decline and incentivize membership growth including evangelism, mega facilities, appealing ministry, and church legacy attracting the community. This research sought to prove that if ministries were developed specifically targeting the wants and needs of the missing generations souls would be won for Christ …

Examining The Research To Practice Gap In Targeted Violence Threat Assessment In School Psychology Practice: A Phenomenological Study, Zachary Zilinski

Doctoral Dissertations and Projects

Preventing acts of targeted violence in schools is a necessary good because of institutional and social harms. Acts of targeted violence in school are low probability, though high-impact events have often garnered a high degree of media attention and thus attention from society at large. In lieu of attempts at perpetrator profiling, current best practice approaches emphasize prevention and intervention measures that consider the environmental factors such as school climate that can serve to incubate school violence. School psychology as a field straddles education and applied psychology. For this reason, school psychologists are often called upon to participate in threat …

The Declining Enrollment Of San Diego County High School Music Programs From 2006-2021, Charles James Jirkovsky

Doctoral Dissertations and Projects

Since 2006, many San Diego County High Schools have experienced a dramatic decline in music program enrollment. The effects of the COVID-19 pandemic and the new teaching paradigm served as catalysts that caused some San Diego County high schools to discontinue their music programs entirely. The enrollment statistics for San Diego County high school music programs during the fifteen years from 2006-2021 fall far below the national average. The effects of these changes have left many students and communities with either a struggling music program or without a music program at all. This case study examined a set of San …

Vested Interest And Preparedness Policy: Increasing Preparedness Behaviors Among American Individuals And Families, Nicholas Evan Winters

Doctoral Dissertations and Projects

Natural disasters take place throughout the United States many times annually, from localized storms to hurricanes or earthquakes affecting many states. The federal government develops and implements preparedness policies, which are then translated into state, county, and municipality preparedness policies. Individual and family preparedness is a component of these preparedness policies; however, existing federal preparedness policies fail to prompt American individuals and families to prepare for natural disasters. The purpose of this study is to understand how the failures of the current preparedness policies contribute to the lack of individual and family preparedness and the political, social, and psychological factors …
