The Effects Of Family Dynamics On Relationships, Alexus Nunley

Honor’s College Freeman Research Journal

For my Advanced Statistics class, Professor Floyd assigned us to research and collect data on a topic that we were interested in. Since my goal for my future career is to become a marriage and family therapist, I decided to research if individuals choose their significant other based on their parents. The results of my research led me to wonder about the effects of family dynamics on relationships. Understanding how family dynamics affect relationships matters because it helps explain why individuals choose the partners they do. This research can help reduce relationship departures. Critics argue that family dynamics strongly influence …

Nonacademic Factors That Effect Early College High School Student's Resilency, Amy Draper

Electronic Theses and Dissertations

This qualitative descriptive study was an exploration of how counselors in early college high

schools (ECHSs), administrators in ECHSs, and the technical coaches who support the ECHS

model contribute to students’ resilience toward academic recovery. Using semistructured

interviews and survey questions, a sample of 15 counselors, administrators, and technical

coaches shared factors that impact ECHS recruiting practices, attrition rates, and the educational

success of individual ECHS students. Three themes were extracted from a sample of educators’

descriptions regarding their perception of the ECHS environment and the benefits and challenges

they experienced while working with ECHS students. They included the combined …

Foster Youth Experiencing Homelessness In Texas: An Analysis Of Risk And Protective Factors That Impact Housing Stability, Monique Willoughby

Electronic Theses and Dissertations

While research on youth homelessness continues to grow, not much is known about the differences that exist between states. To address specific concerns effectively, a more nuanced and granular approach to assessment is needed. Specifically, Texas youth who are transitioning from foster and other systems of care into young adulthood and more independent living will need tailored support to adequately address their needs. This study is a step in that direction. Through identification of risks factors that predict homelessness for these youth, social workers, counselors, case managers, and other human services providers and advocates can better assess, plan, and intervene …

The Disappearing Fishermen, Areli Palomo Contreras

Kroc IPJ Research and Resources

The Disappearing Fishermen is one of a series of ethnographic journalism stories about the violence embedded in the web of power structures shaping our global market system. In the Honduran wetlands of the Central American Gulf of Fonseca, these structures result in multiple forms of harm and damage to artisanal fishing communities. During the eighties and the nineties, the shrimp farming industry that settled in these wetlands was conceived to meet the Global North’s “need” for shrimp. Powerful international institutions including the World Bank and development agencies such as USAID provided loans to private companies, while the Honduran government enabled …

Kroc IPJ Research and Resources

I wanted to shed light on the situation of Indigenous women in Colombia and Venezuela, focusing specifically on the situation of Wayuu women living in the northern border of both countries. The identity of an Indigenous woman carries a dual burden—defined by both gender and ethnicity—that determines living conditions and access to rights within a worldview rooted in a collective sense of belonging to an Indigenous people. As a Wayuu Indigenous woman and a human rights researcher, my objective was to identify forms of discrimination by listening to Wayuu women in the territories of both countries. This approach allowed us …

Pathogenicity And Virulence Of Human Respiratory Syncytial Virus: Multifunctional Nonstructural Proteins Ns1 And Ns2, Trudy N Merritt, Jingjing Pei, Daisy W Leung

2020-Current year OA Pubs

Human respiratory syncytial virus (hRSV) is a major cause of lower respiratory tract infections in young children, the elderly, and immunocompromised. Despite its discovery over 60 years ago and the global impact on human health, limited effective prophylactic or therapeutic options have been available for hRSV infections. This has largely been attributed to the legacy of vaccine failure in the 1960s using a formalin-inactivated RSV , which led to enhancement of disease post exposure to hRSV infection and hampered subsequent development of vaccine candidates. Recent FDA approval of vaccines for older adults and pregnant individuals are major advancements but leaves …

Cxcr3-Cxcl11 Signaling Restricts Angiogenesis And Promotes Pericyte Recruitment, Jihui Lee, Megan E. Goeckel, Allison Levitas, Sarah Colijn, Jimann Shin, Anna Hindes, Geonyoung Mun, Zarek Burton, Bharadwaj Chintalapati, Ying Yin, Javier Abello, Lilianna Solnica-Krezel, Amber N. Stratman

2020-Current year OA Pubs

BACKGROUND: Endothelial cell (EC)-pericyte interactions are known to remodel in response to hemodynamic forces; yet there is a lack of mechanistic understanding of the signaling pathways that underlie these events. Here, we have identified a novel signaling network regulated by blood flow in ECs-the chemokine receptor CXCR3 (CXC motif chemokine receptor 3) and one of its ligands, CXCL11 (CXC motif chemokine ligand 11)-that delimits EC angiogenic potential and promotes pericyte recruitment to ECs during development.

METHODS: We investigated the role of CXCR3 on vascular development using both 2- and 3-dimensional in vitro assays, to study EC-pericyte interactions and EC behavioral …

Higher Abundance Of Disturbance-Favoured Trees And Shrubs In European Temperate Woodlands Prior To The Late-Quaternary Extinction Of Megafauna, Elena A. Pearce, Florence Mazier, Ralph Fyfe, Charles W. Davison, Signe Normand, Maria Antonia Serge, Paolo Scussolini, Jens Christian Svenning

School of Geography, Earth and Environmental Sciences

Large herbivorous mammals strongly influence vegetation structure by creating and maintaining open areas and causing disturbance within closed woody habitats. The herbivores alive today in Europe are only a small remnant of the large species that existed in high diversity and abundance before modern humans. The extinction of so many large herbivores during the last 50,000 years, and the loss of megaherbivores (body weight ≥1000 kg) from most of the continent before the Pleistocene–Holocene transition, is likely to have had cascading effects on vegetation structure and composition. To evaluate these effects within the European temperate forest biome, we examine the …

Solid-State Nmr Compositional Analysis Of Sputum From People With Cystic Fibrosis, Kathy Duong, Evan Moss, Courtney Reichhardt

2020-Current year OA Pubs

People with the genetic disease cystic fibrosis (CF) often have chronic airway infections and produce airway secretions called sputum. A better understanding of sputum composition is desired in order to track changes in response to CF therapeutics and to improve laboratory models for the study of CF airway infections. The glycosylated protein mucin is a primary component. Along with extracellular DNA, mucin gives rise to the high viscoelasticity of sputum, which inhibits airway clearance and is thought to promote chronic airway infections in people with CF. Past studies of sputum composition identified additional biomolecular components of sputum including other proteins, …

Carceral Apartheid: Centering State Responsibility For The Racial Order, Ion Meyn

Cardozo Law Review

Racial harms are often attributed to private ordering. But the power of White communities to subordinate communities of color is not a constellation of private acts independent of state violence. When scrutinized, acts of racial exclusion, segregation, and violence persist to the extent they are aligned with the political order and backed by the state’s violent guarantee. The knowledge that any resistance to these acts will be met with state retribution bristles in the background.

There are different ways in which state violence produces and reproduces the racial order: (1) direct violence; (2) a violent guarantee backing communal acts of …

A One-Egg Wonder: Working To Cure Judicial Gender Bias And Increase Access To Pre-Embryos For Infertile Parties, Nicole Marks Kaufman

Cardozo Law Review

The first live birth of a child conceived from in vitro fertilization (“IVF”) happened in 1978. Today, over eight million children have been born through IVF procedures. The first dispute over the resulting pre-embryos was in 1990 when the Tennessee Supreme Court outlined a balancing approach with a presumption favoring non-use of the pre-embryos for courts to follow when resolving these matters. Numerous states have taken differing approaches—some have taken a contractual approach, others an approach requiring contemporaneous mutual consent before there can be a departure from the status quo, and very few state legislatures have directly addressed how to …

Soil Organic Matter Processes From The Treetops To The Clay Particle: The Role Of Climate, Minerals, And Organic Matter Chemistry In Soil Carbon Accumulation And Stability, Jessica G. Murray

All Graduate Theses and Dissertations, Fall 2023 to Present

Soils store more carbon than plants and the atmosphere, yet release ten times more carbon dioxide (CO₂) to the atmosphere than human activities each year. Small shifts in the balance of soil carbon storage and soil carbon emissions could make climate change less severe, by acting as a sink for the carbon plants pull from the atmosphere, or make climate change worse, by releasing even more planet-warming greenhouse gases. The processes governing whether soils store or release carbon depend on tiny soil microorganisms which convert plant carbon to soil organic matter, releasing CO₂ in the process. In …

Moose Movement In An Urbanizing Landscape, Lucian R. Mcdonald

All Graduate Theses and Dissertations, Fall 2023 to Present

Humans disturb the environment in specific places and at specific times. As wildlife learn to navigate these disturbances, they react as they would to the risk of predation. Wildlife biologists can identify where and when these disturbances will lead wildlife to congregate by comparing geospatial data, such as metrics that represent vegetation, topography, or other environmental conditions, to known locations of the animal(s) in question. In Chapter I, I discuss the impact of human disturbances, like urbanization and roads, on wildlife behavior. In Chapter II, I compare the risk of moose-vehicle collisions (MVCs) to moose selection of urbanized landscapes to …

Investigating The Biochemical Aspects Of Meat Tenderness, Chandler D. Stafford

All Graduate Theses and Dissertations, Fall 2023 to Present

Of all the attributes that define beef's eating quality, tenderness stands out as one of the most important. Previous studies have shown that consumers are willing to pay a premium for beef that is guaranteed to be more tender and are more likely to purchase that product repeatedly. Yet, due to the influence of numerous internal and external factors, controlling and predicting tenderness remains to be difficult. However, among these factors, meat aging is the primary contributor to end-product tenderness, as it is recognized for breaking down muscle tissue via enzymes present within the muscle. The activity of these enzymes …

Development Of A Multidimensional Index Of Fall Risk For Older Adults: The Cache County Study, Alexandra G. Hammond

All Graduate Theses and Dissertations, Fall 2023 to Present

One out of four adults over the age of 65 are estimated to fall each year in the U.S. alone, with that number expected to rise to 52 million falls per year by the year 2030. Improving accuracy for identification of older adults at a higher risk of falling is increasingly important and may be integral in informing the distribution of limited resources and assist in preventing falls in older adults. This project examined the relationship between previously identified risk factors and fall risk to create multidimensional fall risk indexes for older adults, specific for each sex.

Factors best associated …

Ecological Interactions Of Cougars, Deer, And Wild Pigs In The Central Coast Range, California, Mitchell A. Parsons

All Graduate Theses and Dissertations, Fall 2023 to Present

Wild pigs are an introduced species in the Americas that negatively affect ecosystems in many ways. Previous research has documented their negative effects on water quality and vegetation and their potential to spread disease among wildlife, domestic animals, and humans. However, how wild pigs affect predator-prey interactions between native wildlife has received little attention. This research explores multiple interactions between wild pigs, a native predator (cougars), and a native prey (black-tailed deer). First, I studies cougar diet to understand how frequently pigs are used as prey. During this project, I also placed wildlife cameras at cougar killed prey to monitor …

Immune Variation Across Different Contexts In Non-Model Systems, Kwanho Claudia Ki

All Graduate Theses and Dissertations, Fall 2023 to Present

The immune system is important to an animal’s survival against disease-causing agents and physical injuries. Accordingly, many resources are required to maintain and activate the immune system (such as energy). However, as these resources also need to be shared with other important systems of the body, the portion of resources that can be allotted to the immune system is variable. Thus, many different factors may alter how well the immune system operates. My dissertation sought to understand what sorts of factors can lead to changes in the immune system. Reptiles are known to have a very robust immune system. Therefore, …

From Pasture To Plate: Striking An Omega Balance Between Grass-Fed And Grain-Fed Beef Ribeyes - Fatty Acid Composition, Minerals, Soil, And Forage Analysis, Travis Earl Statham

All Graduate Theses and Dissertations, Fall 2023 to Present

Most beef cattle in the US are feedlot-finished where intensive feeding of grains is used to increase weight and yield; however, a minority are raised in grass-fed operations that use exclusive pasture, rangeland, and hay for feeding, possibly leading to benefits for the land, soil, ecosystems, forages, and the meat itself. These operations use a variety of methods, and the goal of this was to recognize differences in the soil and forage metrics to help understand the resulting meat fatty acid composition and mineral content. We collected these samples from 78 sets of farmers while testing 25 sets of grain-fed …

Designing Technology-Enriched Learning Environments: The Effects Of An Agent-Based Computer Model On Biology Students' Understanding Of The Covid-19 Pandemic And The Nature Of Models In Science, April Sullivan

All Graduate Theses and Dissertations, Fall 2023 to Present

Science education researchers have called for increased attention to the science practice of modeling to engage students in authentic scientific inquiry. A major challenge to integrating the modeling practice into science instruction is that students tend to conceptualize models as static end-products of research rather than generative tools for theory-building. Engaging students in using computer models, specifically agent-based computer models (ABMs), to explain and predict scientific phenomena could improve students' understanding of models in science. In this design-based research project I investigate the effects of an ABM-supported learning environment on high-school biology students' understanding of the COVID-19 pandemic and the …

Genomic Selection For Dwarf Bunt Resistance In Winter Wheat, William Krause

All Graduate Theses and Dissertations, Fall 2023 to Present

Dwarf bunt (DB), caused by the pathogen Tilletia controversa J.G. Kühn [as 'contraversa'], is a fungal disease that poses yield and grain quality risks to winter wheat (Triticum aestivum) production in the Intermountain West and abroad. The infection replaces the grain with a collection of spores that are spread by wind during the following harvest. In addition to wheat, DB also infects other cereal grains and wild grasses. Genomic selection (GS) is a plant breeding method that can determine percent infection of related varieties by using phenotypic data and genetic data within a prediction model. A panel …

Responses Of Medical Cannabis To Daily Light Integrals Higher Than Summer Sunlight: Yield, Morphology, And Quality, James D. Nielson

All Graduate Theses and Dissertations, Fall 2023 to Present

Cannabis sativa L. is a crop with growing medical and commercial significance. However, cannabis is not as well studied or understood as many of the most common crops. A novel area of research surrounds how much light the plant can tolerate or use to keep increasing flower yield. In agriculture, light intensity is often measured by how many light particles interact with a given area in a second, referred to as photosynthetic photon flux density (PPFD). For example, at Utah State University in Logan, Utah, during the peak of summer, the sun's light intensity can reach about 2000 μmol·m^{-2 …}
