Stable Complexity: Verbal Inflection In Prominent And Frequent Environments, Lukas Denk

Linguistics ETDs

Despite presenting challenges for speakers, complex linguistic features such as lexically conditioned inflection (LCI) persist across different languages. LCI forms part of not entirely predictable paradigms which require lexeme-specific knowledge to master. Moreover, LCI remains one of the oldest morphological phenomena in certain languages. Previous research has linked the persistence of such complexity to language-external factors like geographic and social circumstances of speech communities.

This dissertation delves into the question whether language-internal properties are associated with the distribution of inflectional complexity. LCI is compared with other inflectional paradigms across 41 genetically and geographically distant languages. The study shows that LCI …

Strategies To Reduce Chronic Disease: Adding Role To Community Health Workers, Ingrid J. Renwanz Dnp, Pmhfnp-Bc/Aprn, Msn, Rnc

Doctor of Nursing Practice (DNP) Projects

Background: Underserved, rural, immigrant, low-income Latinx communities need to strengthen healthcare access to improve their quality of life (Capitman et al., 2009; McCartney et al., 2019; Save the Children [STC] Organization, 2021). Non-communicable chronic disease of physical and behavioral origin is the leading cause of morbidity for adults and children in Latinx communities (Campbell et al., 2020). Estimates of greater than 30% of the Latinx populations within the United States have these health needs, with projections to reach 28% of the U.S. population by 2060 (Eghaneyan & Murphy, 2019; Ortega et al., 2018).

Servant-Leadership In The Military: An Investigation Of Servant-Leadership Among Technical Sergeants In The United States Air Force, Tracey M. Richardson, Matthew P. Earnhardt, Tori Morris, Steven M. Walker

International Journal of Servant-Leadership

Servant-Leadership, developed by Greenleaf (1970), is a leadership theory which prioritizes the follower. Greenleaf contended that putting others first as leaders could lead to a change in society. Patterson (2003) developed a model from Greenleaf’s theory which identified several attributes of the Servant-Leadership model including agapao love, humility, altruism, vision, trust, empowerment, and service. In the military, researchers have used Patterson’s construct to conclude that Servant-Leadership does exist in the military. Though some research involving Servant-Leadership and the military has been conducted, there is a dearth in the literature. In the United States Air Force, leadership development for Non-Commissioned Officers …

Absolving Conflict Through Principles Of Servant-Leadership, Brandon Stoddard

International Journal of Servant-Leadership

This article explores the inevitable and unchecked conflicts that arise between people and how it can turn into unmanageable rage and harmed relationships. Both instigators and recipients of conflict are ultimately wounded by its accompanying outcomes. By sharing several examples from my life, including the threat of harm from a deadly weapon towards my three-year-old son by his uncle, I demonstrate the hurt caused by conflict and how principles of servant-leaders can help individuals restore positive associations. When faith is stronger than the bitterness and hostility that often plagues humanity, love offers a longer-term perspective thereby opening a way towards …

Radio Insights Into Gamma-Ray Mysteries, Seth M. Bruzewski

Physics & Astronomy ETDs

In the time since its launch, the \textit{Fermi Gamma-Ray Space Telescope} has provided new and unparalleled views of the $\gamma$-ray sky, dramatically increasing our understanding of sources of high-energy radiation. During that same time, however, its ``unassociated'' sources have provided a consistent mystery: approximately one third of the modern gamma-ray sky remains completely unaccounted for in other electromagnetic regimes. While some of the fainter sources simply pose challenges in achieving the necessary signal-to-noise ratio, others are well constrained and have resisted traditional investigations for years, and in some cases, for over a decade. Radio astronomy has traditionally been the best …

"I Know The Dream Mine Is True": Mormons, Mining, And The Making Of "Bad Religion" In Early Twentieth-Century Utah, Christine V. Shell

American Studies ETDs

In 1894, folksy Mormon farmer-turned-prophet John H. Koyle, Jr, dreamed that an angel from the Book of Mormon showed him where and how to mine for golden ore and Book of Mormon treasures. Shortly afterwards, Koyle and a handful of friends established the “Dream Mine” at the revealed location, and as word spread additional workers joined the cause—for this was a mine destined to save the Church of Jesus Christ of Latter-day Saints and its members from financial and spiritual ruin during the long-foretold apocalyptic “Last Days.”

Koyle’s followers took delight and solace from their participation in the Dream Mine’s …

Green Is The New Black: Exploring How A Philosophical Approach To The Fashion Industry Will Reduce Its Environmental Impact, Darion A. Gibbs

Student Theses and Dissertations

The fashion industry is the third largest contributor to pollution globally, behind only oil and agriculture. It also accounts for one-fifth of the plastic produced annually. Despite its impact, it is hard to trace accountability. For example, mega-retailers often outsource production to developing countries, without strong structures of accountability for their environmental impact. In addition, companies often claim to be environmentally sustainable, but it is easy to inflate the truth, and entities designed to protect consumers have limited enforcement. In this context, who should be held responsible for the fashion industry’s contribution to climate change?

In response, this thesis delves …

Design And Fabrication Of A Low Power 7.2 Terabit Transmitter For Exascale Computing, Scott Mcwilliams

Electrical Engineering Theses and Dissertations

Enhanced Coupled Strength (ECS) gratings fabricated into III-V based devices offer high reflected power per unit length and broad band reflectivity as compared to conventional 1st order gratings, desired qualities for short-haul high speed transmitters that can be implemented without the need for chip-level temperature control, contributing to the low power per transmitted bit. For commercial DBR lasers, the grating reflectivity results in an extremely narrow reflectivity spectrum, which is highly desired for most/many applications, but requires a power hungry thermo-electric cooler to maintain a fixed frequency. The proposed LEAM (laser electro-absorption modulator) requires a broad reflectivity spectrum, which, by …

Transport And Mixing Of Water Masses Across The Southeast Caribbean Ocean Imaged By Seismic Reflection Data, Joseph Renzaglia

Earth Sciences Theses and Dissertations

The Caribbean Sea serves as a major pathway for global thermohaline circulation (THC), which is a complex and vital component of the Earth’s climate system, influencing global heat distribution and oceanic circulation. Though relatively stratified, it is the boundary layer that distributes mass and temperature between the surface waters and the deep ocean where we observe various multiscale mixing processes from mesoscale to fine-scale. In regions where bathymetry is shallower and mechanical mixing forces, such as winds and tides, are more dominant, diapycnal diffusivity is typically stronger, driving vertical mixing. This type of mixing occurs at small scales, typically as …

Characterizing The Ecology Of Plains (Spilogale Interrupta) And Eastern (Spilogale Putorius) Spotted Skunks: A Systematic Literature Review And Population Assessment In Kansas, Jenell De La Peña

Electronic Theses & Dissertations

The plains spotted skunk (Spilogale interrupta) has recently been recognized as a distinct species from the eastern spotted skunk (Spilogale putorius). While once abundant across the central and eastern United States, both species have experienced population declines, resulting in their review for listing under the Endangered Species Act (1973). In Kansas, the plains spotted skunk has suffered a particularly dramatic decline, the last detection in the state having occurred in 2020. Additionally, due to the recent taxonomic split, many past studies reporting on S. putorius ecology actually describe findings of two species, potentially complicating our understanding …
