Investigating Limitations To Nitrogen Fixation By Leguminous Cover Crops In South Texas, Stephanie L. Kasper

Theses and Dissertations

Many farms use leguminous cover crops as a nutrient management strategy to reduce their need for nitrogen fertilizer. Biological nitrogen fixation (BNF) depends on a symbiotic relationship between legumes and nitrogen-fixing rhizobia. Under certain conditions despite inoculation with appropriate rhizobial strains, this symbiosis fails to form. Such failure was observed in a 14-acre winter cover crop trial in the Rio Grande Valley of Texas when three legume species (forage pea, crimson clover, and hairy vetch) produced no signs of nodulation and nitrogen fixation. This study examined nitrogen, phosphorus, moisture, micronutrients and biotic interference as potential causes for the failure and …

The aim of this study was to analyze how prepared early educators are in identifying children that fall under the category of autism …

Evaluation Of Protein Utilization In Low And High Protein Forage Sources And The Economic Value Of Supplementing Field Peas (Pisum Sativum) To Growing Cattle Grazing Crested Wheatgrass Pastures, Braden C. Troyer

Department of Animal Science: Dissertations, Theses, and Student Research

Field peas are widely grown in the panhandle of Nebraska; however, markets quickly become saturated. A two year experiment was conducted comparing field peas to dry distillers grains with solubles (DDGS) as a protein supplement. The objective was to establish a price producers could pay for field peas relative to DDGS. There was a significant difference in ADG due to type of supplement (P = 0.02). Field pea supplemented heifers had 10% lower ADG compared to DDGS supplemented heifers. Economically, this means if DDGS is priced at or $124.58/ 909 kg DM a producer could pay $2.89/27 kg, for …

Selective Harvest Methods And Chemical Treatment Of Baled Corn Residue For Utilization In Growing Calf And Dry Cow Diets, Ashley C. Conway

Department of Animal Science: Dissertations, Theses, and Student Research

Three studies were conducted to evaluate baled corn residue using selective harvest method and anhydrous ammonia treatments to assess utility in growing calf and dry cow diets. Baled corn residue was harvested using conventional rake-and-bale (CONV) method, or harvested using the New Holland Cornrower in which either eight rows (8ROW), or two rows (2ROW) of corn stalks were chopped into the windrow with tailings. Bales were either not treated or ammoniated at 5.5% DM. When fed to wether lambs in a mixed ration (65% residue, 30% wet corn gluten feed) to determine digestibility, the 2ROW residue had greater apparent DM, …

How To Protect The Poor Food Insecure In The Mena Region?, Racha Ramadan

Topics in Middle Eastern and North African Economies

The Middle East and North Africa (MENA) region faces important challenges concerning food insecurity reflected in the double burden of malnutrition, under nutrition and over nutrition, with high prevalence of anaemia especially among children and women. Social Protection Programs may play significant role in affecting food security “directly” by affecting food supply and availability through providing basic goods at low prices or through agricultural subsidies. But the SPPs in the region are fragmented, poorly targeted, covering only formal employees with an increasing budget and low adequacy. This yields to an impact on food security and poverty less than what is …

Condition-Dependent Begging Elicits Increased Parental Investment In A Wild Bird Population, E. Keith Bowers, Jonathan B. Jenkins, Alexander J. Mueller, Kelly D. Miller, Charles F. Thomspon, Scott K. Sakaluk

Faculty Publications – Biological Sciences

The coevolution of parental supply and offspring demand has long been thought to involve offspring need driving begging and parental care, leaving other hypotheses underexplored. In a population of wild birds, we experimentally tested whether begging serves as a negatively condition-dependent signal of need or a positively condition-dependent signal of quality. Across multiple years, we supplemented nestling house wrens with food shortly after hatching and simultaneously manipulated corticosterone levels to simulate the hunger-induced increase in glucocorticoids thought to mediate begging. This allowed us to also test whether begging is simply a proximate signal of hunger. Days after supplementation ended, food-supplemented …

The Hemoglobin A1c Of African-Americans/Blacks With Diabetes Mellitus Type Two Using Low-Fat Diabetes Plate Diet, Ednah K. Makori

Doctor of Nursing Practice Projects

Diabetes Mellitus type two (DMT2) is a chronic disease that leads to high blood sugar in the body and if not corrected over a period of time, it leads to development of complications. Some of those complications include blindness, kidney failure, and retinopathy, among others. DMT2 continues to affect many people in the USA, especially African-Americans/Black who have the highest prevalence as compared to other races. Proper diet management especially the Low-Fat diabetes diet helps to decrease Hemoglobin A1c, which could result in reduction of risk of developing complications and morbidity related to DMT2. This project was done to educate …

The Role Of Tbx5 In Sinoatrial Node Differentiation In Mouse Embryonic Stem Cell Derived Cardiomyocytes, Yunkai Dai

All Dissertations

The sinoatrial node of the mouse embryo arises from the wall of the right atrium near the border of the sinus venosus. Early in development this region expresses the transcription factor Tbx5. Because of this, Tbx5 is thought to sit at the apex of a transcriptional cascade leading to sinoatrial node (SAN) differentiation. To test this we produced a mouse embryonic stem cell line B1 (pTripZ-mTbx5; αMHC::GFP) that conditionally overexpresses Tbx5, to determine if this would lead to enhanced SAN differentiation. We found that ES cells overexpressing Tbx5 showed enhanced overall cardiac differentiation and that cardiac cells showed increased beat …

This research study was conducted to understand the phenomenon of preschool enrollment by refugee parents. The phenomenography research methodology was chosen for this study because it explores how a group collectively perceives a phenomenon. In this study, the research addresses how refugee parents perceive enrollment in public preschool programs. The data …

Exploring The Indian Opinion : Interpretations Of Colonialism, Anti-Colonial Activism, And Gandhi's Influence In Three African Countries, 1950-1960., Alexander Ganesha Kaliannan

Electronic Theses and Dissertations

My research began by uncovering connections between the Non-Cooperation movement in India, led by Mohandas Gandhi and the Pan-Africanist movement in Ghana, led by Kwame Nkrumah, illuminating the process in which Nkrumah engaged with Gandhi’s political non-violence and non-cooperation. The research then sought to understand how the Mau Mau uprising acted as anti-colonial activism in Kenya, and how the Indian diaspora in both South Africa and Kenya, were interpreting the colonial response to the Mau Mau. This thesis aims to answer two questions: How did Gandhi’s political philosophies of non-violence influence/inform leaders, activists, and movements in Kenya and Ghana during …

Inspiratory Muscle Recruitment During Swallow And A Comparison Across Airway Behaviors., Allison V. English

Electronic Theses and Dissertations

During swallow, a negative esophageal pressure is present that, along positive pressure from the tongue, which works to move the bolus through the pharynx into the esophagus. This negative esophageal pressure is thought to be produced via recruitment of chest wall inspiratory muscles (diaphragm and parasternal). This current study aimed to examine respiratory muscle recruitment across behaviors which have known inspiratory muscle activity (eupnea, augmented breath and cough) and compare to swallow. It was hypothesized that there would be no significant difference in amplitude and muscle recruitment over 75 ms between swallow and eupnea, but cough and augmented breath would …

Hormone Signaling, Gene Expression, And Mitochondrial Hormone Receptor Expression In Avian Muscle (Cells), Kentu Rushadd Lassiter

Graduate Theses and Dissertations

Mitochondria are vital to the proper growth and function of muscle cells since they’re responsible for the majority of ATP production used for cellular energy. Previous studies have investigated how differences in mitochondrial function affects feed efficiency (FE) in broilers phenotyped for High and Low FE. Low FE broilers have been shown to have increased levels of reactive oxygen species (ROS), thus contributing to higher levels of oxidative stress and damage seen in these birds. Global gene and protein expression studies conducted on breast muscle of the High FE and Low FE phenotypes have suggested that differences in mitochondrial function …

Economic Base In Emerging Economies: Estimating Regional Multipliers In Ecuador, Justin Perry

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

When a subnational input-output matrix is unavailable, a non-governmental organization (NGO) may turn to a shortcut method in order to project its indirect economic impact in a region. The location quotient is the most common choice in developed nations, but has serious theoretical flaws in a developing-nation context. We explore the minimum requirements method as a cost-effective yet robust method to project the impact of an NGO in the Imbabura province of Ecuador. We find that every $1 of exogenous local spending stimulates between $1.32 and $1.62 of indirect economic impact in the region.

The Impact Of Master’S Level Education On The Assessment And Intervention Of Pediatric Swallowing, Andrea Seagren

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Purpose: Pediatric swallowing disorders is increasing in prevalence as medical advancements are made. This increase raises the need for more speech-language pathologists (SLPs) to be involved in the assessment and intervention of pediatric swallowing. However, discrepancies exist in the amount and level of education being provided during academic coursework in the area of pediatric swallowing.

Method 1: The investigation had a two-tier approach. Part one included a survey specifically targeting SLPs who graduated within the most recent accreditation standards (2014 to present) and masters level students in their second year of graduate school (n=100). Part two explored academic courses offered …

The Impact Of Exposure To The Thin Ideal On Chocolate Cravings In U.S. -Born Women, Kathryn M. Helm

Psychology

Food cravings are experienced by a large proportion of the population and have a variety of negative implications- including overweight/ obesity, heart disease, and type 2 diabetes. Prior research has shown a lack of support for biological causes of craving. As such, we look to other factors such as culture, cognition, and sex, to explore why such factors have an influence on craving. The purpose of this study is to look at the impact of viewing thin ideal images on chocolate cravings in United States born women-including (but not restricted to) their reports of ambivalence towards chocolate. Participants were randomized …

Avocado Root Rot: Steep, Rocky Terrain And Biodiversity Help Protect Small Farmers In Post-Conflict Colombia, Morgan Frankel

Master's Theses

In recent years, small avocado producers in coastal Colombia returned to their farms after decades of war to discover they must battle the pathogen Phytophthora cinnamomi devastating their trees. While this disease is well-described in the U.S., Australia, and Europe, no previous research has examined environmental correlates of P. cinnamomi in avocado in the diverse tropical agroecosystem of the Colombian Montes de Maria. I used agroecosystem inventory, in-field diagnostics, and disease observations to describe avocado agroecosystem diversity and identify relationships among P. cinnamomi presence, root rot disease, slope, pH, soil compaction, elevation, and distance to the household in remote smallholder …

Photovoltaic Waste Management And Implementing Extended Producer Responsibility In The Solar Industry In California, Lee-Tan Lu

Master's Theses

Electronic waste issues impact humans and the environment, primarily because most industrial designs have not considered the impact of products when they reach their end-of-life (EOL) stage. This study focuses on photovoltaic (PV) modules that are widely installed in California residential properties. While PV modules do not generate waste while operating, they will become waste at the end of their expected lifespan of 25 to 40 years. Thus, it is important to identify PV waste management strategies before the materials in the modules become a discard problem. In California, despite hazardous materials that are used in the production of PV …

"Notjustgirls": Exploring Male-Related Eating Disordered Content Across Social Media Platforms, Jessica Pater, Lauren Reining, Andrew D. Miller, Tammy Toscos Phd, Elizabeth D. Mynatt

Mirro Center Articles

ABSTRACT: Eating disorders (EDs) are a worldwide public health concern that impact approximately 10% of the U.S. population. Our previous research characterized these behaviors across online spaces. These characterizations have used clinical terminology, and their lexical variants, to identify ED content online. However, previous HCI research on EDs (including our own) suffers from a lack of gender and cultural diversity. In this paper, we designed a follow-up study of online ED characterizations, extending our previous methodologies to focus specifically on male/masculine-related content. We highlight the similarities and differences found in the terminology utilized and media archetypes associated with the social …

Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, Donya L. Ralph-Quarnstrom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Consumer demand for organic products has shown double-digit growth in recent years encouraging the development of a wider range of goods (Greene, 2017). Americans with an annual household income under $30,000 actively purchase organic foods at nearly the same rate as households with over $75,000 in annual incomes, 42% versus 49% (Greene et al., 2017). Previous research observed the adoption of organic farming practices on a combination of different grains, fruits and vegetables, meat, and dairy products from across the globe. However, this is the first study to examine the adoption of organic wheat in the Western U.S. By addressing …
