Investigation Of Yy Production Methods For Invasive Channel Catfish Ictalurus Punctatus Population Management, Andrew M. Wisniewski

All Graduate Theses and Dissertations, Fall 2023 to Present

Aquatic invasive species are one of the leading causes of native fish declines in the Southwestern United States. Channel Catfish Ictalurus punctatus were introduced into the Colorado River Basin, including the San Juan River, New Mexico, Colorado, and Utah for fishery enhancement during the 20th century. This introduction has contributed to the decline of native species and despite intensive mechanical removal efforts, the Channel Catfish population has persisted in the San Juan River. The Trojan Sex Chromosome approach is a promising eradication strategy that proposes the production and release of Trojan sex chromosome carriers (YY) to skew a targeted population’s …

Understanding And Predicting Precipitation Characteristics In The United States Through Machine Learning, Numerical Modeling And Measurements, Cody Luther Ratterman

All Graduate Theses and Dissertations, Fall 2023 to Present

Precipitation is one of the most important yet uncertain variables in the climate system. It varies dramatically in terms of timing, accumulation, rate, and phase, depending on location, season, circulation patterns, and atmospheric conditions. Precipitation forecasts, especially snowfall, are essential to supporting drought mitigation and water management in the Intermountain West. Because rainfall and snowfall lead to opposite effects on snowpack, accurately partitioning rain and snow is important to estimate snowpack levels, winter recreation, mountain ecosystems and runoff. The research findings in this dissertation have advanced the understanding and prediction of precipitation and snowpack in the U.S. by addressing the …

Strain Monitoring And Site Characterization At Birds Landing From Transmission Tower Implosions Recorded Using Das And Nodal Stations, Prajwal Panthi

All Graduate Theses and Dissertations, Fall 2023 to Present

When two old electrical transmission towers in the Sacramento River Delta in California were demolished by Pacific Gas and Electric Company, Utah State University saw an opportunity hiding inside the demolition. Because one of the towers stood close to the Sacramento River and its protective levee, they used the controlled collapse not only to monitor strains in the levee and surrounding ground, but also to learn what lied beneath the ground surface.

To capture this event, the researchers buried a 1.4-kilometer fiber optic cable along the ground and connected it to a system called Distributed Acoustic Sensing (DAS), which can …

The Role Of Individual Specialization In Migration Phenology And How Restored Habits Are Used By Native And Nonnative Fishes, Austin Garner

All Graduate Theses and Dissertations, Fall 2023 to Present

Native fish species around the world have declined due to habitat loss, habitat fragmentation, and the spread of non-native species. Because these problems often happen at the same time and interact, recovery efforts can stall unless they address all of the factors limiting a species' comeback. The June sucker (Chasmistes liorus), native only to Utah Lake, UT, has declined for many of these reasons, though its recovery effort has made significant progress due in large part to a successful hatchery program. Yet, the recovery efforts have not yet been able to establish a self-sustaining population in Utah Lake, …

Microbes In Pollination Systems: Effects On Pollinator Health, Floral Traits, Nectar Robbing, And Plant Fitness, Valerie Nicole Martin

All Graduate Theses and Dissertations, Fall 2023 to Present

Flowers produce nectar to attract pollinators, but nectar is also a habitat for yeasts and bacteria that arrive via pollinators, robbers, and other visitors. These microbes consume nectar sugars and release byproducts that change the smell and taste of nectar. Whether these changes affect how pollinators find and choose flowers, and whether they ultimately affect how many seeds a plant produces, is not well understood. In this dissertation, I studied how a common nectar yeast and a plant-associated bacterium affect the scent of wildflowers, the behavior of bumble bees and hummingbirds, and plant reproduction in montane meadows in central Colorado. …

Autistic Students' Experiences With Hybrid Flexible Instruction In Higher Education: An Interpretive Phenomenological Study, Tracey Nicole Barr

STEMPS Theses & Dissertations

During the twenty-first century, autistic learners have enrolled in colleges and universities in greater numbers; however, the majority of research focused on their experiences in higher education has found them to be less academically successful than their neurotypical peers. The academic skills that autistic students bring to higher education are often tempered by social, emotional, and self-regulative challenges. The body of research focusing on autistic learners’ experiences in higher education is currently limited and focused primarily on fully in-person and online course models. No extant research has focused on autistic students’ experiences with hybrid or blended course models.

This interpretive …

De Facto Captivity In The Land Of The Free: Exploring The Confining Effects Of Network And System Avoidance, Brianna Ovalle

Sociology & Criminal Justice Theses & Dissertations

Encroaching state surveillance has primarily targeted people of color living in urban, inner cities, resulting in both much higher likelihoods of encountering state agents and the consequences of such contact. The ceaseless surveillance has led some individuals to engage in protective behaviors aimed at minimizing encounters with agents of the CLS. These behaviors are adaptable to present risks of surveillance and contact with the system. While there are various types of avoidance, the focus of this research is system avoidance and network avoidance. Previous literature for both types of avoidance focuses on the experiences of lower SES men. Further, as …

Time-Frequency Analysis Of Arterial Pulse Signals Of Cardiovascular Disease Patients Measured By A Microfluidic-Based Tactile Sensor, Md Mahfuzur Rahman

Mechanical & Aerospace Engineering Theses & Dissertations

This dissertation presents a single-degree-of-freedom (SDOF) based time–frequency analysis framework that can simultaneously extract a comprehensive set of cardiovascular autonomic indices from arterial pulse wave recordings obtained at rest and post-exercise, supporting non-invasive monitoring of autonomic recovery during cardiac rehabilitation. The framework rests on three technical contributions.

First, an SDOF analytical model of motion artefacts quantifies two physically distinct distortion mechanisms: additive baseline drift and Time-Varying System Parameter (TVSP) generated distortion of the Tissue-Contact-Sensor (TCS) stack. Baseline drift is slowly varying and removable by filtering; TVSP distortion rides on all harmonics of the true pulse signal and cannot be removed …

Background: Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated.

Procedure: We obtained data on maternal and perinatal characteristics, congenital anomalies, and pediatric sarcoma diagnoses for all live births in nine states. We used Cox proportional hazards regression to estimate the hazard ratio (HR) and 95% confidence interval (CI) of sarcoma (overall and by subtype) among children with non-syndromic congenital anomalies. We considered all non-syndromic …

A Finite Element Model To Analyze Crack-Tip Fields In A Transversely Isotropic Strain-Limiting Elastic Solid, Saugata Ghosh, Dambaru Bhatta, S. M. Mallikarjunaiah

School of Mathematical & Statistical Sciences Faculty Publications

This paper presents a finite element model for the analysis of crack-tip fields in a transversely isotropic strain-limiting elastic body. A nonlinear constitutive relationship between stress and linearized strain characterizes the material response. This algebraically nonlinear relationship is critical as it mitigates the physically inconsistent strain singularities that arise at crack tips. These strain-limiting relationships ensure that strains remain bounded near the crack tip, representing a significant advancement in the formulation of boundary value problems (BVPs) within the context of first-order approximate constitutive models. For a transversely isotropic elastic material containing a crack, the equilibrium equation, derived from the balance …

Prediction Of Pasture Condition In The Kimberley Rangelands Of Western Australia Using Simple Classification Tree Models, Ben Nestor, Kath Ryan, Charles Martin, Philip Thomas, Chris Hetherington, Matthew Fletcher, Robert Sudmeyer, Karyn Reeves

Natural Resources Research Articles

Pasture condition assessments assist pastoralists, regulators, and policy makers in making informed decisions around livestock production and the preservation of natural resources in the Kimberley rangelands of Western Australia (WA). Reliable qualitative assessments of pasture condition require assessors with extensive expertise, which means frequent and reproducible assessments can be difficult to achieve. To develop a quantitative approach that can complement existing qualitative assessment approaches in the Kimberley, we investigated the use of simple classification tree models to predict pasture condition using assessment data from the Western Australian Rangeland Monitoring System (WARMS). Quantitative traits were derived from WARMS observation data for …

Wisdom In Counseling And Psychotherapy: A Conceptual Model For Practice, Mitchell Waters

Posters

Wisdom is increasingly recognized as an important construct in counseling and psychotherapy, yet its clinical application remains underdeveloped. This article presents an integrative model of wisdom as a dynamic, context-sensitive capacity that coordinates cognitive, affective, temporal, and spiritual processes in response to complex life challenges. The model includes four dimensions: (a) cognitive-affective integration, combining emotion and reason; (b) temporal integration, linking past experiences with future possibilities; (c) intrinsic spirituality, fostering meaning-making and reducing egocentric bias; and (d) regulatory flexibility, enabling adaptive shifts among domains. Implications for therapeutic practice, outcomes, and future research are discussed.

The Price Of Possessiveness: How Parental Materialism Undermines Child Psychological Wellbeing, Miao Li

Sociology Publications

Materialism, a value system that places the pursuit of possessions at the core of happiness and life meaning, is a dominant cultural force in modern societies. While its associations with individual well-being are well-documented, its intergenerational implications remain understudied. This study conceptualizes materialism as a potential family stressor contributing to the intergenerational transmission of stress. An intergenerational crossover model of materialism was tested using data from 1,996 parent-child pairs in Zhengzhou, China. Results indicate that higher parental materialism is associated with stronger materialistic values in children, weaker family relationships, and more frequent parental comparisons, each of which is linked to …
