Problem Solving In Latino Families, Eliza Torres

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this dissertation is to learn if the quality of problem solving, parent engagement, and child engagement improve as a result of participating in a parenting intervention. The quality of problem solving was coded by independent observers watching a 5-minute videotaped task. Parent and child engagement were also coded by an observer and were evident in behaviors such as making eye contact, using good social skills, using humor, minimizing problems, and showing empathy were also rated by individual coders who were blinded to treatment/control groups. Each parent-child pair had a total of three scores, one for each variable …

Integration Of Nutrition Education Classes Into English As Second Language Classes For Refugees, Sarah Gunnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Each year approximately 73,000 refugees are resettled into the United States because it is unsafe for them to return to their country of origin. Resettlement agencies help refugees learn about their new environment and provide assistance with housing, food, English classes, and job skills training. The goal of resettlement programs is to help refugees become self-sufficient as quickly as possible.

Recently resettled refugees face many challenges that make it difficult to eat healthy food. Transportation, English skills, and conflicting work hours are some of the barriers to receiving nutrition education. This research evaluated the integration of nutrition lessons into English …

Social Organization And Decision Making In North American Bison: Implications For Management, Ryan A. Shaw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Social organization varies widely among herbivores, and the level of social organization in bison is widely debated. I hypothesized that when mother-daughter relationships are allowed to develop, bison form long-term associations. In my study, 25 treatment mothers were selected from a free-ranging herd and kept together with their calves, while 25 control females had their calves forcefully removed. Treatment mothers and offspring had by far the greatest number of associations with a greater percentage of individuals with a half weight index (HWI) > 0.50. The strongest associations (HWI > 0.31) were among treatment mothers and their offspring. Moreover, these associations persisted over …

Systematics Of Multillidae (Hymenoptera) With Special Emphasis On Dasymutilla And Their Allies, Kevin A. Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Velvet ants are solitary wasps that are excellent candidates as model organisms for studying evolutionary phenomena like mimicry and biogeography. They can also be used in conservation studies because of their local abundance. Their abundance, coupled with parasitic lifestyle on native pollinators, suggests they will be economically important as native pollinators are implemented more widely. Velvet ants, however, are rarely studied and their research potential is drastically hindered by lack of phylogenetic and taxonomic data and lack of interest in the scientific community. In this dissertation, I sought to overcome the hindrances to mutillid research with a holistic systematic research …

Rationalizing Structure, Stability, And Chemical Bonding Of Pure And Doped Clusters Isolated And Solvated Multiply Charged Anions, And Solid State Materials, Alina P. Sergeeva

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chemistry is the study of materials and the changes that materials undergo. One can tune the properties of the known materials and design the novel materials with desired properties knowing what is responsible for the chemical reactivity, structure, and stability of those materials. The unified chemical bonding theory could address all these questions, but we do not have one available yet. The most accepted general theory of chemical bonding was proposed by Lewis in 1916, though Lewis’s theory fails to explain the bonding in materials with delocalized electron density such as sub-nano and nanoclusters, as well as aromatic organic and …

Assessing And Enabling Independent Component Analysis As A Hyperspectral Unmixing Approach, Matthew R. Stites

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Perhaps the most common way to distinguish materials is by color. For example, this is typically how one determines, from some distance, whether a material on the ground is grass (green), soil (brown), or asphalt (black). To accomplish this, most digital cameras (along with the human eye) produce images that are comprised of three different colors, called spectral bands: red, green, and blue. The combination of these bands enables material discrimination. Working in the same way, but on a much larger scale, hyperspectral imaging sensors produce images that are comprised of hundreds of spectral bands. This combination of bands enables …

Unsteady Computational Fluid Dynamics (Cfd) Validation And Uncertainty Quantification For A Confined Bank Of Cylinders Using Particle Image Velocimetry (Piv), Brandon M. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Computational modeling is of particular interest to science and engineering for the improvement of design and development of products and research of physical phenomena. However, confidence in a computational model must be validated prior to it's application through comparison to experimental data. The nuclear power industry has interest in the application of computational modeling to plant design, safety, and development for the increased understanding of heat transfer and fluid dynamics. Fluid dynamics, particularly time-varying phenomena within the reactor core, has a strong effect on heat (energy) transfer and transient accident scenarios of a nuclear power plant. While this work was …

Exitus: An Agent-Based Evacuation Simulation Model For Heterogeneous Populations, Matthew T. Manley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Evacuation planning is important for businesses given the continuing occurrence of both natural and human-caused disasters throughout the world. Unfortunately, the traditional fire-drill approach is impractical for many large organizations but especially those responsible for airports and sports arenas. The purpose of this research was to develop a new computer program capable of simulating large scale evacuations in such buildings. The program, called Exitus, is different from other evacuation simulators in the way it considers the physical, psychological, and social characteristics of individuals with disabilities during emergency situations.

In this research, Exitus was used to simulate evacuations of three buildings …

The Role Of Fine-Scale Habitat Associations In Structuring Spider Assemblages: Determinants Of Spatial Patterns In Community Composition, Stephanie M. Cobbold

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ecologists strive to identify the mechanisms that drive the identity and abundance of species in different locations, because a better understanding of such factors enables them to better predict the effects of habitat modification on organisms, and to identify landscapes in which species are likely to benefit from conservation interventions. However, there is still no consensus on the mechanisms behind geographical variation in species diversity. The primary objective of this dissertation was to focus on spider assemblages to investigate how the fine-scale habitat associations of organisms may drive the composition of their communities at larger scales. Research was conducted in …

Spider Community Composition And Structure In A Shrub-Steppe Ecosystem: The Effects Of Prey Availability And Shrub Architecture, Lori R. Spears

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Habitat structure is cited as an important factor influencing organisms, but few studies investigate whether habitat structure interacts with other environmental variables to affect community dynamics. The purpose of this study was to determine, using field experiments, the importance of prey availability and shrub architecture on a spider community in northern Utah, USA. We were also interested in determining whether surrounding shrub architectures influence spider and prey responses.

Our results suggest that spider distribution, abundance, and biodiversity are influenced by shrub architecture. Shrub architecture influenced spiders both directly and indirectly via associated changes in prey availability. Spiders were also directly …

Dads' Parent Interactions With Children-Checklist Of Observations Linked To Outcomes (Piccolo-D): Developing An Observational Measure Of Father-Child Interaction, Sheila Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Intervention programs providing support for father parenting skills need a practical but psychometrically strong observational measure of fathers’ early positive parenting interactions with children. The primary purpose of this project was to develop a valid, reliable observational measure of father-child interaction, based on research and theory, that predicts child outcomes, identifies fathers’ strengths, and will be useful for home visiting practitioners. This study sought to fulfill this need by developing a new measure called Dads’ Parenting Interactions with Children—Checklist of Observations Linked to Outcomes (PICCOLO-D) for home visitors to use to identify fathering strengths. Developed with extant video observations of …

The Mechanisms Of Hydride Exchange, Organic Combination And Displacement Reactions, Weifang Hao

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary aim of this dissertation was to seek the answer to the question: “Is the single transition-state model appropriate for the fundamental reactions in organic chemistry?” The goal was accomplished by performing enormous kinetic data collection and detailed mechanistic analysis on several typical fundamental organic chemical reactions. Three new methodologies for differentiating between a simple one-step and complex multi-step mechanism were developed and extensively confirmed during the application in the kinetic studies of all of the reaction discussed in this dissertation. The three methods consist of (1) half-life dependence of kapp, (2) sequential linear pseudo-first-order correlation, and (3) revised …

Treatment Of Pediatric Obsessive-Compulsive Disorder: Utilizing Parent-Facilitated Acceptance And Commitment Therapy, Jennifer Yardley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pediatric obsessive-compulsive disorder (OCD) affects as many as 2.7% of children. Pediatric OCD is associated with significant distress for both families and children in multiple domains. Unfortunately, the majority of children with OCD do not receive adequate treatment. Without treatment pediatric OCD often persists into adulthood.

The current primary psychological treatment for pediatric OCD is cognitive behavioral therapy (CBT) with exposure and response prevention (ERP). However, there are multiple limitations of this treatment. Some children either do not respond to current treatments or respond only minimally, while others drop out or refuse treatment.
Exposure-based treatments yield problems with treatment adherence, …

Use Of Rumen Modifiers To Manipulate Ruminal Fermentation And Improve Nutrient Utilization And Lactational Performance Of Dairy Cows, Christopher M. Dschaak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A series of lactation studies reported in this dissertation hypothesized that supplementing different rumen modifiers would have consistent responses on ruminal fermentation and lactational performance under optimal rumen conditions.

The first experiment investigated the influence of magnesium exchanged zeolite on ruminal fermentation and lactational performance. Intake of dry matter (DM), milk yield, milk fat, and feed efficiency were not affected. Milk protein concentration tended (P = 0.15) to be higher for cows fed the zeolite. Ruminal pH tended to increase (P = 0.11) by feeding the sodium bicarbonate or the zeolite.

A second lactation experiment determined …

On-Farm Water Management Game With Heuristic Capabilities, Mohammed Z. Shaban

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Improved on-farm irrigation practices can result in more economical farming, and better productivity. Very little has been done with regard to improved training tools that can be used to promote better and more effective on-farm irrigation practices. Games considered as an effective decision support tools in which players are able to test alternatives, and demonstrate the effects of their decisions, in a short time, and without being afraid of making mistakes. Training tools in the form of games promotes what is called “learning based on experience” through a schematic version of reality, and observing the effects.

The WaterMan game was …
