Case Study: Teacher Mindset And Its Impact On Instruction In An At-Risk Classroom, Michelle L. Rice
Electronic Theses and Dissertations
The achievement gap between disadvantaged students and their advantaged peers is a problem that has been a concern since the Brown vs. the Board of Education Supreme Court case in 1954. The problem continues to exist, and little progress has been made in closing the gap. Research shows a teacher’s mindset can significantly impact the achievement gap. This mixed-methods case study aims to examine teacher mindsets in at-risk, suburban elementary campuses to determine its impact on instruction. A purposeful selection sample of nine teachers from various levels, experience, and specialties in grades PK-5 took part in the study. The quantitative …

Intellectual Property Rights In The Seed Industry: Barriers To Sustainable Agriculture, Elena A. Filatova
Electronic Theses and Dissertations
The dynamics of the dominant industrial agriculture system restrict the seed industry’s innovative landscape, leading to significant negative consequences including an exacerbation of environmental risks which threaten global food security. This thesis explores how exclusionary intellectual property rights (IPRs) in the context of the seed industry constrict innovation, evolutionary pathways, and opportunities for the implementation of sustainable agriculture methods. To overcome these barriers, the application of an open source framework to seed innovation, specifically through the platform of the Open Source Seed Initiative, is evaluated as a tool for enhancing innovative capacities in seed development while broadening the accessibility and …
Understanding Patterns And Functional Impacts Of An Invasive Tree And Its Biological Control In A Riparian System, Annie L. Henry
Understanding Patterns And Functional Impacts Of An Invasive Tree And Its Biological Control In A Riparian System, Annie L. Henry
Electronic Theses and Dissertations
Invasive species have become an inextricable part of the landscape, particularly in riparian plant communities, and removal is often a key component of restoration programs. Biological control (biocontrol) is a method of removal that is often both efficient and effective. However, the impact of biocontrol on target species and indirect effects from invasive species removal can be hard to predict. While monitoring the impact of invasive species removal usually involves some species-based assessment such as changes in diversity, historically dominant species or native species, these strategies do not typically provide insight into the mechanisms underlying plant community response to removal. …
Testing A Sociocultural Model Of Body Image In Women Athletes With Disabilities, Brooke R. Lamphere
Testing A Sociocultural Model Of Body Image In Women Athletes With Disabilities, Brooke R. Lamphere
Electronic Theses and Dissertations
Evidence suggests that athletes and people with disabilities (PWD) experience multiple body images that change relative to their social context (e.g., Petrie & Greenleaf, 2012). The powerful influence of social factors on body image and disordered eating in women athletes is well-documented (e.g., Schaefer, et al., 2015; Fitzsimmons-Craft et al., 2014), as is the centrality of the body in the lived experience of athletes and PWD (Behel & Rybarczyk, 2012; Galli et al., 2016); yet, limited research has explored the effects of social factors on body image in athletes with disabilities (i.e., AWD; e.g., Galli et al., 2016; Sousa et …
Children’S Health And Maternal Work Activities, Termeh Tavangar
Children’S Health And Maternal Work Activities, Termeh Tavangar
Electronic Theses and Dissertations
I estimate the effect of poor child health on maternal labor force participation. Mothers of health-impaired children may decide not to work and stay at home to take care of their children. Alternatively, mothers may choose to enter the labor force to pay for these children’s additional resources. Which action dominates is the empirical question I answer in this paper. I control for the potential endogeneity of a child’s health status by using an instrumental variables approach. I find that if mothers have a child in poor health, the probability that the mother works is decreased by thirteen percentage points, …

Operationalizing A New Method For Defining And Scaling Social Innovations Using Tiny Home Communities As A Case Study, Jennifer H. Wilson
Operationalizing A New Method For Defining And Scaling Social Innovations Using Tiny Home Communities As A Case Study, Jennifer H. Wilson
Electronic Theses and Dissertations
Social innovations are new approaches to addressing unmet need. In an increasingly globalized and interconnected world, social innovations propagate rapidly in response to the dynamic conditions of our modern world. An example of an emergent social innovation, tiny home communities are gaining traction as a more economically, socially, and environmentally favorable response to homelessness and inadequacies in the current shelter and housing system. The use of tiny homes communities (that is, intentional clusters of small-scale structures) as an innovative response to homelessness is relatively new. As such, there is limited empirical evidence on the topic. Lack of research and defined …

Management And Dietary Strategies To Mitigate Environmental Stressors In Northern Plains Cattle Feeding Systems, Warren Carl Rusche
Electronic Theses and Dissertations
Three studies were undertaken to examine strategies to mitigate environmental stress faced by Northern Plains cattle feeders. In the first study, 46 feedlot managers from SD (n = 21), MN (n = 6), and NE (n = 19) were surveyed on use and perceptions of heat stress (HS) mitigation strategies. All respondents avoided cattle handling during heat stress events and incorporated some method of HS mitigation. Buildings or shades were perceived as the most successful strategy (60.9%) and were most commonly named as strategies managers would like to employ (63% for shades and 17.4% for buildings). Increasing dietary corn silage …
Identification Of Loci Influencing Teosinte Crossing Barrier 1 (Tcb1) Efficacy In Maize By Quantitative Trait Loci (Qtl) Mapping And Genome-Wide Association Study (Gwas), Namrata Maharjan
Electronic Theses and Dissertations
Pollen cross-contamination has been a major problem for maize breeders. Various mechanical methods applied to avoid the contaminations are ineffective. The genetic factors related to maize fertilization can be used to develop an effective method to prevent pollen contamination. Pollen rejection ability controlled by Teosinte crossing barrier 1 (Tcb1) is such a genetic system. Silks possessing dominant Tcb1-s reject pollen possessing the recessive allele (tcb1). Successful fertilization occurs when Tcb1-s pollen falls upon tcb1 silks. The efficacy of dominant Tcb1-s was, however, reduced when repeatedly backcross with maize inbred lines, which suggests that there are modifiers to Tcb1-s. To find …

Develop Biochar-Based Controlled Release Nitrogen Fertilizers, Zhisheng Cen
Develop Biochar-Based Controlled Release Nitrogen Fertilizers, Zhisheng Cen
Electronic Theses and Dissertations
The current efficiency of conventional nitrogenous fertilizers (e.g. urea, ammonium sulfate, etc.) in agricultural practices is low, fluctuating from 30 to 40%. Approximately 60% of nitrogenous fertilizers were wasted due to vaporization into the air, runoff or leaching into water systems. The lost nitrogen (N) resulted in not only high production cost but also serious environmental problems, such as greenhouse gas (N2O) emission in the atmosphere, algal blooms, oxygen depletion, fish kills, and loss of biodiversity in surface water due to eutrophication or pollution. To address these problems, this study aimed to utilize low-cost biochar-based materials to develop a controllable, …
Milk Phospholipids Extraction Using Switchable Solvents, Kaavya Rathnakumar
Milk Phospholipids Extraction Using Switchable Solvents, Kaavya Rathnakumar
Electronic Theses and Dissertations
Phospholipids (PLs) found in milk are of great interest due to their health and nutritional benefits associated with their consumption. By-products generated during the manufacture of dairy products represent a source of PLs with potential for value-added opportunities. Currently, the extraction of PLs from by-products results in overall lowefficiencies, and it involves subsequent solvent separation and lipid recovery. This dissertation studied the extraction of milk PLs from by-product streams with a tertiary anime (N, N-dimethyl cyclohexylamine, CyNMe2) as a switchable hydrophilicity solvent. This type of solvents can be reversibly switched between a hydrophobic and hydrophilic form in the presence or …

The Role Of The Auxin Biosynthesis And Signaling In Soybean Root Nodule Development, Mucahid Bozkus
The Role Of The Auxin Biosynthesis And Signaling In Soybean Root Nodule Development, Mucahid Bozkus
Electronic Theses and Dissertations
Nitrogen(N) is one of the most important plant nutrients for plant growth and yield, however, its abundance in the soil is not sufficient for profitable crop production. The use of chemical fertilizers helps address soil N deficiency in agriculture. However, due to the environmental pollution resulting from excessive use of fertilizers, alternative forms of N for agriculture are a necessity. Leguminous plants such as soybean (Glycine max) form a symbiotic association with N-fixing rhizobia to meet their N demands. Legume-rhizobia symbiosis results in the formation of unique structures called nodules where rhizobia convert atmospheric nitrogen into plant usable forms, thus …

Biomechanical Investigation Of Plant Vascular Tissue For Bio-Inspired Design And Flexible Composites, Mukesh Roy
Electronic Theses and Dissertations
Since the inception of evolution, nature has continuously optimized all the natural materials. These optimizations are so efficient that scientists and engineers have started taking inspiration from nature. Such inspiration-based solutions provide sustainable development of new materials with enhanced structural properties and functionalities (such as stiffness, stability, toughness, self-healing etc.). This variety of properties and functionalities is mainly due to the hierarchical organization of such components. Abstraction of the hidden cues of the hierarchical organization, principles and underlying structure-function relations are some of the critical approaches of bioinspired materials design. Inspiration from animals and plants has helped develop the design …

Improving Nutritional Properties And Extractability Of Pea Proteins For Human Consumption Via Fungal Bioprocessing, Camille Massmann
Electronic Theses and Dissertations
Yellow peas are a rich source of protein and phytochemicals. Peas are compatible with many diets restricted by sensitivities, allergies, or personal choice. As a result, peas are gaining popularity in food markets, despite the challenges they present. The biggest challenges for pea proteins in food markets are high content of fiber, starch, and saponins. These components cause processing challenges and create undesirable textures and bitter flavors. Pea proteins are typically extracted with alkaline extraction or air classification methods which result in 80% and 50% protein products respectively. With low protein purity, these products are not competitive with other, more …

Cortisol In Hair As A Measure Of Chronic Stress During Sow Gestation And The Pattern Of Cortisol In Blood During Parturition In Sows, Talia Everding
Cortisol In Hair As A Measure Of Chronic Stress During Sow Gestation And The Pattern Of Cortisol In Blood During Parturition In Sows, Talia Everding
Electronic Theses and Dissertations
Cortisol is known as the stress hormone, as it influences many metabolic processes to maintain glucose homeostasis during stressful experiences, including physical and psychological stress. It can be detected in biological matrices such as blood and hair and is released rapidly during sudden stressors and continuously during longterm stress. Blood cortisol fluctuates rapidly in response to acute stressors like pain, exertion, and fear; in hair cortisol accumulates steadily over the period of hair growth and may be useful for detecting chronically elevated cortisol resulting from long-term stress. The objective of this research was to, 1) determine the influence of a …

Are Us Government Foreign Aid Flows And Fdi Flows Intertemporally Related? An Investigation Of Twenty-Three Countries In Sub-Saharan Africa, Ravi Kumar Datt Panchagnula
Electronic Theses and Dissertations
In this thesis, I test my central hypothesis that United States government foreign aid flows and FDI flows from anywhere in the world to Sub-Saharan Africa are intertemporally related; thus, I test to what extent FDI flows follow—and, thus, are caused by—aid flows or to what extent aid flows follow—and, thus, are caused by—FDI flows. My panel dataset includes twenty-three Sub-Saharan countries and spans 1991 to 2018. Based on the results of pooled-OLS and panel fixed-effects regressions, and panel Granger causality tests, I show that aid and FDI are intertemporally related. Additionally, Granger-causality is bidirectional: FDI Granger-causes United States government …

Genome-Wide Association Analysis Permits Characterization Of Stagonospora Nodorum Blotch (Snb) Resistance In Hard Winter Wheat, Rami Altameemi
Electronic Theses and Dissertations
Stagonospora nodorum blotch (SNB) is an economically important wheat disease caused by the necrotrophic fungus Parastagonospora nodorum. SNB resistance in wheat is controlled by several quantitative trait loci (QTLs). Thus, the identifying of novel resistance/susceptibility QTLs is crucial for continuous improvement of the SNB resistance. Here, the hard winter wheat association mapping panel (HWWAMP) comprising accessions from breeding programs in the Great Plains region of the US, was evaluated for SNB resistance and necrotrophic effectors (NEs) sensitivity at the seedling stage. A genome-wide association study (GWAS) was performed to identify singlenucleotide polymorphism (SNP) markers associated with SNB resistance and …

U.S. Consumers' Acceptance And Willingness To Pay For Genetically Modified And Genome-Edited Foods, Bindu Paudel
Electronic Theses and Dissertations
Even though genetically modified (GM) crops have a lot of economic potential for producers and consumers, they have not been widely accepted due to increasing concerns related to food safety, human, animal, and environmental health. Unlike GM technology, genome-editing technology does not involve the transfer of genetic materials. It is simpler, cheaper, more precise, and faster relative to GM technology and has immense potential for incorporating producer and consumer traits. Genome-editing technology, as a novel process, not has been explored much from the consumer’s side. This study uses a nationally representative survey of 1,573 U.S. consumers to examine their acceptance …
