Wildfire-Altered Geotechnical Soil Properties And Their Impact On Subsequent Landslides, James M. Kellogg

Theses and Dissertations

Wildfires result in altered landscape as well as altered soil properties. Wildfires result in conditions that are more susceptible to geotechnical hazards introducing a potential for cascading events in the surrounding area. Shallow landslides are common geohazards that result in a post-wildfire landscape. With an ever-increasing trend in wildfires, the need to better understand the impact wildfire-altered soil properties play on shallow slope instability is critical to evaluating risks to existing or planned development, mitigation of potentially hazardous conditions, prioritization of post-wildfire planning, and post-wildfire response preparation. The primary objective of this study is to provide a comprehensive overview of …

Relationships Between Heat Alerts, Extreme Heat Days, And Heat Related Mortality Within The Contiguous United States Over The Last Decade, Maggye Jo Brand

Theses and Dissertations

A gap of knowledge lies within the hazard of extreme heat within the United States and the public’s response and perception of their own vulnerability. Even with constant communication from meteorologist at the National Weather Service and within the broadcast industry, there are still ongoing issues which include the possibility that ambient air temperature from fixed sites do not accurately reflect what the general population is experiencing, that the thresholds for excessive heat warnings are not appropriate, and that the most vulnerable individuals do not have the knowledge, and/or ability to protect themselves when extreme heat does occur. Assessment of …

Identifying Barriers To Data Use On U.S. Beef Cow-Calf Operations And Developing Solutions To Improve Cow-Calf Record-Keeping, William Isaac Jumper

Theses and Dissertations

Cattle health and production records (CHPR) are data collected by cattle producers and veterinarians in the form of measurements, observations, counts of events over time, and physiologic attributes that describe individual and group-level health and production. These data are useful to both veterinarians and cattle producers for making evidence-based decisions on cow-calf operations. Currently, there are no uniform, industry-wide methods of capturing and recording CHPR in the U.S. cow-calf industry. Although many cow-calf producers in the U.S. are thought to collect some form of CHPR, it is believed that relatively few are doing so in an electronic manner that facilitates …

Results indicate that the PG juveniles had significantly smaller femoral lengths-for-age than VR …

​​Evaluating The Utility Of Trial-Based Functional Analyses Of Inappropriate Mealtime Behavior: A Comparison Of Identified Functions Across Functional Analysis Methods, Meredith Huff Staggers

Theses and Dissertations

A critical first step in addressing problem behavior is to identify the function of the problem, or reason for engaging in the problem behavior, using systematic assessment procedures known as a functional analysis (FA). The literature consistently demonstrates the effectiveness of FAs, and variations of FAs (e.g., trial-based functional analysis [TBFA]) for assessing a variety of topographies of problem behaviors across populations, age groups, and settings; however, the use of TBFAs for assessing the function of inappropriate mealtime behavior (IMB) has been documented in the literature only once. The purpose of the current study was to contribute to the research …

Host-Acquired Virus Genes Support An Ancient Antiviral Role Of The Pirna Pathway In Dipterans, Rebecca Christian

Theses and Dissertations

Endogenous viral elements (EVEs) have been recently investigated as a source of transgenerational immune memory. These “viral fossils” are abundant in Aedes mosquitoes and partner with the host’s primary antiviral defense system, the RNA interference (RNAi) pathways. This partnership appears unique to mosquitoes, which encode an expansion of the Piwi endoribonucleases. To interrogate EVE-Piwi partnerships and their role in antiviral defense, I performed a comparative small RNA analysis of two naturally occurring EVE-virus pairs – one in the mosquito Aedes albopictus, and one in the midge Chaoborus americanus. Both express an EVE related to the nucleoprotein of their …

"What Would It Mean For Us To Seem 'Good' To Each Other?": Contemporary Black Women+ On Fat Phobia And Misogynoir, Devon Ariel Thomas

Theses and Dissertations

White supremacy's impact on Black bodies is well-known. Starting with the enslavement of millions of Africans and their descendants, to Reconstruction, Jim Crow laws, the race-based War on Drugs, mass incarceration, police murders--and now, through fat phobia. Fat phobia--the hatred of and discrimination against fatness--is problematic for all bodies because it limits basic opportunities and privileges. However, it becomes particularly dangerous at the intersection of structural racism and misogyny. Francis Beale argues that as both Black people and women+, Black women+ carry a "double strike" against them; consequently, they experience both racism and misogyny, termed "misogynoir" by Moya Bailey. Language …

Dad Talk: Father-Child Communication When A Parent Has Cancer, Elizabeth A. Reed

Theses and Dissertations

Most individuals are impacted by a cancer diagnosis, in fact 54% of Americans say they or someone in their immediate family has been diagnosed with cancer at some point (CBS Interactive, 2017). While most Americans have a family member with cancer, most research has been done to understand the mother-daughter relationship during such a time. Unfortunately, there is little research regarding father-child communication during a cancer diagnosis, and father-child communication is understudied. The father-child dyad is an important relationship that impacts a child throughout their lives (Fellers & Schrodt, 2021). To further understand these relationships and how cancer may impact …

Experiences Of Youth In Confinement: Pathways Of Racial-Ethnic Disparities In Juvenile Corrections, Kimbla Newsom

Theses and Dissertations

Of the vast body of research focusing on the racial and ethnic disparities (RED) phenomenon in the juvenile justice system, much of the attention has been at critical points of system contact such as arrest and disposition, while overlooking what happens within critical stages such as confinement facilities. This dissertation investigates the ways in which youth experiences in juvenile confinement facilities differ across racial and ethnic groups. Findings reveal that race and ethnicity is a significant predictor of a youth experiencing more control-oriented interventions, longer lengths of stay in confinement, and fewer connections to reentry services. The dissertation concludes with …

The Role Of Developmental Stage, Compensatory Support, And Coping In The Relationship Among Adverse Childhood Experiences, Mental Health, And Resilience In Emerging Adults, Melanie Abbondola

Theses and Dissertations

Children and adolescents who experience adverse childhood experiences (ACEs) often must deal with mental and physical effects lasting well into adulthood. However, much research shows ACEs are related to poorer mental and physical health in adulthood. Much less work has focused on the psychological and social resources that can create resilience. This study examined how compensatory social support and coping strategies potentially moderate the relationship between ACEs and mental health outcomes, and if the age/developmental stage at which the ACEs occurred, and the frequency and intensity of the ACEs affected mental health. Self-report data were obtained from 241 emerging adults, …

Or Read The Wikipedia Entry For The Parable Of The Tower Of Babel But Imagine It’S 2023 This Time And We’Re Getting So Close Just Give The Artist A Little More Of Your Money, David Thonis

Theses and Dissertations

Systems and their inherent design underlie everything in contemporary life. Design exists to facilitate interaction, to ease workflow, to keep us producing. As such, it exerts its own control.

Through disassembling recurring conventions in design, I look to break with preconceptions of logic. To deny functionality. In doing so, my intention is to dislocate the user from the usual patterns of applicable systems.

The resulting discomfort may feel strange, disembodied, but it should be embraced. Long have capitalism’s solutions created more problems. In the face of this complexity, and beyond it, there can be freedom.

The Flex Voice In The Soundtracks For The Nintendo Game Boy, Matthew Dineiro

Theses and Dissertations

The Nintendo Game Boy had a sound chip which allowed for only three pitched voices and one unpitched percussive voice. These limitations affected the music that was written for this video game system. Of the three pitched voices, one voice typically performs the melody, and one voice typically is the bass and harmonic foundation. This thesis analyzes the third voice, typically in the middle of the musical texture, and the various functions that it can hold. As is discussed, the middle voice sometimes pairs in harmony with the melody or the bass. In other cases, however, it forms a musical …
