The Impacts Of Maturation And Experience On Volumetric Neuroplasticity In Solitary And Social Bees, Mallory A. Hagadorn

All Graduate Theses and Dissertations, Fall 2023 to Present

Some animals are incredibly social, living and working together as one cohesive group. Alternatively, many animals are solitary, never living with and rarely interacting with others. A large body of biological research has focused on understanding the role that brains play in promoting these behavioral differences across species. Even so, it remains unclear why some brains facilitate social behavior while others do not. My dissertation aims to advance our understanding of this concept by characterizing bees’ brains and how they change over a lifetime. Bees are beneficial for investigating relationships between the brain and social behavior because some species are …

Virtual Structures Based Autonomous Formation Flying Control For Small Satellites, Tyson K. Smith

All Graduate Theses and Dissertations, Fall 2023 to Present

Many space organizations have a growing need to fly several small satellites close together in order to collect and correlate data from different satellite sensors. To do this requires teams of engineers monitoring the satellites orbits and planning maneuvers for the satellites every time the satellite leaves its desired trajectory or formation. This task of maintaining the satellites orbits quickly becomes an arduous and expensive feat for satellite operations centers. This research develops and analyzes algorithms that allow satellites to autonomously control their orbit and formation without human intervention. This goal is accomplished by developing and evaluating a decentralized, optimization-based …

Phenology Of The Invasive Balsam Woolly Adelgid, Adelges Piceae (Ratz.) (Hemiptera: Adelgidae), On Subalpine Fir In Northern Utah, Elizabeth L. Rideout

All Graduate Theses and Dissertations, Fall 2023 to Present

Balsam woolly adelgid (BWA) is an invasive true fir pest in North America. Native to Europe, BWA was first discovered in Utah attacking subalpine fir in 2017. Recent BWA-caused subalpine fir mortality in northern Utah has prompted the need for baseline biological research to support pest management. Small-bodied and blending easily with its environment, BWA is a challenging pest to detect and study. Phenology, or the timing and characteristics of life stages through the year, of BWA varies depending on elevation and climate and is unstudied in Utah. This research focuses on defining aspects of BWA’s phenology, including the number …

Evaluating Implementer Preference For And Correspondence Between Structured Descriptive Analysis And Trial Based Functional Analysis, Kacy Rodamaker

All Graduate Theses and Dissertations, Fall 2023 to Present

Determining the function of maladaptive behavior aides in the creation of effective intervention measures to change that behavior. Three assessments that are used to determine behavioral function include the trial based functional analysis (TBFA), structured descriptive analysis (SDA), and antecedent-behavior-consequence (ABC) recording. In the present study, we compared the time it took to conduct each of these assessments as well as the similarity between the functions identified by each assessment. Additionally, we compared procedural acceptability and implementer preference between the SDA and TBFA by collecting survey results from a staff participant who implemented the two measures with the support of …

Using Telehealth To Teach Caregivers Mand Training Using A Speech Generating Device, Sara Jeppson

All Graduate Theses and Dissertations, Fall 2023 to Present

Children with ASD often have struggles with social communication and developing a functional vocal output. Alternative and augmentative communication (AAC) can be used in different modes such as speech generating devices (SGDs) to help these individuals develop a vocal output. Caregivers are optimal to aid their children in learning these communication skills. Past studies such as Suberman and Civindini-Motta showed that behavioral skills training (BST) can be effective to teach caregivers communication training using an SGD. The current study aimed to replicate the procedures of Suberman and Civindini-Motta but extended it by adapting the procedures described using telehealth.

Dominant Cognitive Strategy In Aphantasia, Sarah N. Pope

All Graduate Theses and Dissertations, Fall 2023 to Present

The purpose of this research was to explore the impact on thinking when an individual is not able to "see with a mind's eye." This is known as aphantasia and is the reduction or absence of visual imagery, which can have large impacts on problem solving and remembering one's own past. The current study examines these impacts by exploring the different ways in which thinking may occur, verbal-analytical, visual imagery, spatial imagery, and how a one's dominant thinking strategy affects performance on a paired work task, a mental rotation task, and an object memory task. Comparing those with typical imagery …

Relative Hepatotoxocity, Carcinogenicity, And Toxicogenomics Of Select Dehydropyrrolizidine Alkaloids In Mice, Michael J. Clayton

All Graduate Theses and Dissertations, Fall 2023 to Present

Dehydropyrrolizidine alkaloids are arguably the most important plant derived toxins in terms of impact on human and animal health. Dehydropyrrolizidine alkaloids are a large group of chemically related compounds found in 3% of flowering plants worldwide. Human exposure occurs from ingestion of herbal products including teas supplements or contaminated grain. Animals are exposed through contaminated feed or grazing. There are at least 350 identified toxic PAs, from more than 6,000 plants. The toxins primarily cause liver damage, but some are proven to cause cancer. Indidvidual dehydropyrrolizidine alkaloids vary in their toxic effects. Riddelliine is the only dehydropyrrolizidine alkaloid with extensive …

Restoration Strategies For Wetlands In The Arid West: Seeding And Planting Approaches For Lakeshore Ecosystems, Jes Braun

All Graduate Theses and Dissertations, Fall 2023 to Present

Wetlands are widely recognized for their valuable benefits such as providing habitat, improving water quality, and reducing the impacts of flooding. However, wetlands face threats from development, drought, and invasive species. This is particularly apparent in the arid west, where upstream water use and drought make water scarcer and contribute to dramatically changing water levels. Here, I investigated revegetation techniques for lakeshore wetlands, using Utah Lake as a case study. Although recent management efforts have minimized invasive Phragmites cover, the desired plant communities are not returning as quickly as needed, highlighting the need to research restoration techniques. Through my research, …

Metapopulation Genomics Of American Goshawks In The Intermountain West, Megan M. Sidran

All Graduate Theses and Dissertations, Fall 2023 to Present

Understanding a species dispersal ecology and population dynamics is essential to effectively manage and conserve a species. As advancing technology improves our knowledge of species movements, it is becoming clear that many species form metapopulations to some extent. A metapopulation is a network of interconnected subpopulations that exchange reproductive individuals with subpopulations occupying nearby patches. Metapopulations have been observed in a variety of species, ranging from plants to vertebrates, and can vary greatly in their dynamics (level of connectivity and gene flow) based on the species behavior and life history strategy.

Forming a metapopulation can add much resilience to the …

Essays On The Economics Of Hurricanes, Haishan Yang

All Graduate Theses and Dissertations, Fall 2023 to Present

This dissertation explores how Hurricanes Katrina and Rita affected the economy in New Orleans and nearby areas in Louisiana. Using a variety of econometric techniques, my dissertation aims to understand the effects of these storms on employment, wages, and housing prices.

In the first essay, I focus on employment in New Orleans. I find that Katrina led to significant and lasting job losses in nearly every sector, while the construction sector stood as an exception, recovering within just three months. Interestingly, wages increased in most sectors. This suggests that with fewer workers available, those who remained became more valuable, leading …

Reducing Inputs And Adding Value To Turfgrass Systems Through Clover Inclusion And Plant Growth-Promoting Rhizobacteria Applications, Paige E. Boyle

All Graduate Theses and Dissertations, Fall 2023 to Present

Recently, the US has seen an expansion in the amount of turfgrass land cover (lawns, parks, roadsides, sports fields, and golf courses), as well as an interest in reducing fertilizer, water, and pesticide use in these grass systems. To help maintain quality and function while reducing resource inputs, two promising approaches have emerged: planting clover into lawns and applying plant growth-promoting rhizobacteria.

White clover and grass mixtures have been studied for their ability to cut down on fertilizer usage and provide a uniform, dark green lawn, but other clover types have not been as widely studied and may provide similar …

Organisational Drivers And Sustainability Implementation In The Mining Industry: A Holistic Theoretical Framework, Prince Amoah, Gabriel Eweje

Research outputs 2022 to 2026

While few studies have examined the role of institutional pressures on sustainable business practices, there is a dearth of empirical research regarding the influence of internal organisational characteristics on sustainability implementation in developing countries. This paper examines internal organisational features and how they influence multinational companies (MNCs) operating in a resource-rich developing country to embrace and embed sustainability into corporate policies and practices. The findings show that the history of past sustainable practices, the level of internationalisation and managerial cognition internally drive MNCs to implement sustainability in their host countries. We discuss that managerial cognition drives MNCs to embrace sustainability …

How Does Apolipoprotein E Genotype Influence The Relationship Between Physical Activity And Alzheimer’S Disease Risk? A Novel Integrative Model, Jaisalmer De Frutos Lucas, Kelsey R. Sewell, Alejandra García-Colomo, Shaun Markovic, Kirk I. Erickson, Belinda M. Brown

Research outputs 2022 to 2026

Background:

Wide evidence suggests that physical activity (PA) confers protection against Alzheimer’s disease (AD). On the other hand, the apolipoprotein E gene (APOE) ε₄ allele represents the greatest genetic risk factor for developing AD. Extensive research has been conducted to determine whether frequent PA can mitigate the increased AD risk associated with APOE ε₄. However, thus far, these attempts have produced inconclusive results. In this context, one possible explanation could be that the influence of the combined effect of PA and APOE ε₄ carriage might be dependent on the specific outcome measure utilised.

Mapk1 Promotes The Metastasis And Invasion Of Gastric Cancer As A Bidirectional Transcription Factor, Yue Wang, Zheng Guo, Yueli Tian, Liang Cong, Yulu Zheng, Zhiyuan Wu, Guangle Shan, Yao Xia, Yahong Zhu, Xingang Li, Ying Song

Research outputs 2022 to 2026

Background: The Mitogen-activated protein kinase 1 (MAPK1) has both independent functions of phosphorylating histones as a kinase and directly binding the promoter regions of genes to regulate gene expression as a transcription factor. Previous studies have identified elevated expression of MAPK1 in human gastric cancer, which is associated with its role as a kinase, facilitating the migration and invasion of gastric cancer cells. However, how MAPK1 binds to its target genes as a transcription factor and whether it modulates related gene expressions in gastric cancer remains unclear. Results: Here, we integrated biochemical assays (protein interactions and chromatin immunoprecipitation (ChIP)), cellular …

Village-Level Processing Of Pangi (Pangium Edule Reinw.) Seeds By The Obu Manuvu Improves The Edibility And Level Of Some Nutritional Factors [Research Note], Rovi Gem E. Villame-Gayagas, Jennifer P. Fronteras, Maria Christna D. Nacar, Aaron P. Lorilla, Pedro A. Alviola Iv

The Philippine Agricultural Scientist

Pangi (Pangium edule Reinw) seed is known to be a poisonous material. However, it becomes safe for consumption after processing. This study determined the effect of village-level processing by the Obu Manuvu community of Marilog District, Davao City, Philippines on the antinutrient and nutritional composition of Pangi seeds. Processing methods involved washing with running water for about 15 s, boiling in water for 30 min, and soaking in flowing water in a nearby river overnight. Results showed that after processing, the levels of antinutrients such as cyanogenic glycosides and oxalates were reduced significantly (p < 0.05) by 99.15% and 78.23%, respectively. Further, the tannin content was also significantly reduced by 96.15%. The crude fat content significantly increased (p < 0.05) by about 54%. Crude ash and fiber decreased, while protein did not change significantly (p < 0.05). Minerals such as calcium and zinc increased (p < 0.05) by 221.43% and 64.39%, respectively while the iron and manganese levels remained unaffected. Findings of the study suggested that the processing method by the Obu Manuvu effectively reduces the level of antinutrients, thereby improving the edibility and safety of Pangi seeds. Further, the processing method improves the level of some nutrients, specifically crude fat, calcium, and zinc.
