Relations Among Academic Program Elements And Students' Sense Of Belonging, Rosemary Ashby

Undergraduate Honors Theses

This thesis studies specific elements of an academic program and their relationship with students’ sense of belonging. To gather data, participants responded to a questionnaire that contained items designed to understand their experience in their major. The quantitative portion asked about the program elements (independent variables) and used the General Belongingness Scale to measure their sense of belonging (dependent variable). This also included questions that had participants report their perception of how each element affected their sense of belonging. The final item was open-ended and asked for their general thoughts on belonging in their program. The findings suggest that the …

A Comparison Of Rfssw And Rsw For Automotive Manufacturing, Damon Michael Gale

Theses and Dissertations

Historically, automotive body panels have been made of steel and joined by a process called resistance spot welding (RSW). However, in efforts to reduce vehicle weight to improve the energy efficiency of the vehicle, automotive manufactures have begun substituting aluminum in place of steel. While aluminum can be joined with RSW, a myriad of challenges arise from doing so. These challenges result in less consistent weld quality and accelerated electrode wear. Refill friction stir spot welding (RFSSW) is an emerging joining technology that could replace RSW as it is believed to be capable of creating superior joints in thin sheet …

Discharge-To-Water Level Conversion Using Monthly Duration Curves (Dwl-Mdc): Enhancing The Utility Of The Geoglows Ecmwf Hydrological Model, Darlly Judith Rojas Lesmes

Theses and Dissertations

Flood early warning systems are crucial for disaster risk reduction strategies, enabling communities to take timely action against threats. However, the effectiveness of these systems depends on accurate and timely hydrological data, particularly river discharge and water level measurements. Unfortunately, many regions, face significant challenges in obtaining hydrological data, especially discharge data due to outdated rating curves, high equipment costs, and logistical constraints. Water level measurements, by contrast, offer reduced uncertainty and are often more accessible, providing an alternative for hydrological modeling in data-scarce regions. To address these limitations, we developed and validated the Discharge-to-Water Level Conversion Using Monthly Duration …

Controlled intracellular delivery of biomolecular cargo is critical for developing targeted therapeutics and cell reprogramming. Conventional delivery approaches (e.g., endocytosis of nano-vectors, microinjection, and electroporation) usually require time-consuming uptake processes, labor-intensive operations, and/or costly specialized equipment. Here, we present an acoustofluidics-based intracellular delivery approach capable of effectively delivering various functional nanomaterials to multiple cell types (e.g., adherent and suspension cancer cells). By tuning the standing acoustic waves in a glass capillary, our approach can push cells in flow to the capillary wall and enhance membrane permeability by increasing membrane stress to deform cells via acoustic radiation forces. Moreover, by coating …

Stress, Screens, And Social Skills: Parental Stress As A Longitudinal Predictor Of Preschool Social Behavior Mediated By Parental Technoference, Sarah Ashby

Theses and Dissertations

This study examines the longitudinal relationship between parental stress, parental technoference, and preschool children's social behavior, including physical aggression, relational aggression, and prosocial behavior. Using data from Project M.E.D.I.A., the study explores how parental stress may be linked to disruptions in parent-child interactions through increased use of digital media, termed "technoference." It was predicted that an increase in parental stress would increase physical and relational aggression, and decrease prosocial behavior over time, as mediated by parental technoference. A sample of 460- parent-child dyads was analyzed across three time points using structural equation modeling. Despite expectations, results did not find significant …

The Impact Of Positive-To-Negative Teacher Interaction Ratio On Student Performance, Naomi L. Phillips

Theses and Dissertations

Challenging behavior is a growing problem for teachers. Praise has been promoted as a positive strategy for addressing problem behavior. The ratio of praise-to-correction (positive-to-negative) may be important to the effectiveness of praise. A 4:1 ratio has been recommended as optimal to improve student performance. This ratio has never been experimentally tested. There is little known of the feasibility and social validity for maintaining a high positive-to-negative ratio. The purpose of this study was to evaluate the effect of a 4:1 positive-to-negative ratio (PNR) on problem behavior and academic performance of junior high students with an intellectual disability classification in …

Frequent and unresolved conflict is a significant relationship risk factor for divorce, but it has also been shown that religion strengthens marriages, specifically in ways that give direction and motivation for couples in resolving marital conflict or other marital hardships. Thus, a study of how successful religious couples resolve conflict is pertinent in helping us better understand how to strengthen marriages and families. Our qualitative study of 113 highly religious women of diverse faiths and races found that women’s perceived relationship or connection with God reportedly impacted conflict resolution and coping with marital hardship. Results suggest greater reconciliation and unity …

Design And Synthesis Of Bimetallic Catalyst And Multifunctional Peptide Catalysis For Organic Synthesis And Synthesis Of Proteolysis Targeting Chimeras (Protacs) For Sphk1 And Sphk2, Mariur Rodriguez Moreno

Theses and Dissertations

In the first part of this dissertation (chapters 1-4) we discuss the development of bimetallic and monometallic palladium complexes scaffolded on 2-phosphinoimidazole ligands and their application to cross-coupling reactions. Specifically, we discovered a bimetallic Pd(II) dimer that performs a tandem arylation/annulation reaction to produce naphthalene products from aryl iodides and ketones (Chapter 2). We then show that bimetallic Pd(II) and Pd (I) complexes have different activity in different transformations and that the starting oxidation state of our catalysts is important for reactivity (Chapter 3). For example, we demonstrate that our Pd(I) dimer is much more active in Buchwald- Hartwig amination …

Drainage Area Limitations Of Single Watershed, Peak Flow Estimates From Nrcs Methods, Timothy Alexander Maughan

Theses and Dissertations

Most roadway design sections of state Departments of Transportation predict peak flow for culvert design using Natural Resources Conservation Service (NRCS) TR-20 methodology. Even though the approach is more than 50 years old, there is no clear guideline for how large a single watershed drainage area may be while remaining appropriate for predicting peak discharge with this method. Our objective is to identify the drainage area where TR-20 peak flow predictions significantly deviate from flow frequency predictions. We aim to recommend to the Nebraska Department of Transportation (NDOT) a range of basin drainage areas appropriate for predicting peak flow using …

Cellular Air Quality Sensors With Lora Backchannel A Robust Sensor Suited For Remote Deployment In Harsh Environments, Joseph R. Miera

Theses and Dissertations

Air quality significantly impacts health and overall quality of life, making its measurement essential. However, most affordable air quality devices are designed only for use within WiFi range and cannot handle extreme temperatures, limiting their usefulness for people in remote or extreme environments, such as regions with harsh winter climates. This limitation is concerning, as winter often brings worse air quality due to temperature inversions that trap pollutants and increase fuel burning for heating. Inversion is a problem as close to home as Utah Valley, and as far away as Ulaanbaatar, Mongolia. Most low-cost air quality sensors are not built …

Family Ties: How Families Of Origin And Procreation Influence Women’S Migration And Integration, Becca Goldrup

Undergraduate Honors Theses

Women's migration is an increasingly important focus of interest in understanding the family-level factors shaping individual and family-level migration decisions. Utilizing interviews with 30 immigrant women residing in Utah who migrated to the US at three different ages (childhood, young adulthood, and later adulthood), I ask: “How do familial relationships impact the immigration experience for women in the US, and how does this vary by age at migration?” I find that family significantly shapes women's migration decisions and experiences post-migration for women of all ages, but this influence has subtle differences based on their age at migration. Women who migrated …

Analyzing The Relationship Between Tree Canopy Coverage And Snowpack In The Great Salt Lake Watershed, Kyle J. Bird

Undergraduate Honors Theses

This study examines the influence of tree canopy coverage, climate, and topography on snow water equivalent (SWE) within the Great Salt Lake Watershed. Using SNOTEL data, NLCD land use/land cover rasters, t-tests, and multiple linear regression (MLR), the study analyzed SWE variability in relation to canopy density, winter precipitation, elevation, temperature, and latitude. Initial t-tests showed significant differences in SWE between sites with canopy coverage below and above 70%, yet tree canopy was excluded as a significant predictor in the MLR model. Instead, SWE was primarily explained by mean winter precipitation, elevation, average winter high temperatures, and latitude. Additionally, canopy …

"All Power Over Ouranos And Gaia": The Maiestas Domini Supra Caelum Motif In Matthew 28:18 And The Junius Bassus Sarcophagus, Calan Christensen

Studia Antiqua

The maiestas domini supra caelum motif, as depicted in the central vignette of the upper register of the Junius Bassus sarcophagus, is widely understood as epitomizing a Christian ideal or an eschatological adventus as opposed to a representation of any “historical” biblical narra- tive. Nevertheless, this paper addresses the compelling iconographical al- lusion between the Bassus enthronement scene over Caelus and the final chapter of Matthew, specifically highlighting Jesus’s declaration of divine power “ἐν οὐρανῷ καὶ ἐπὶ γῆς.”

Through an examination of the relevant contemporaneous theological and ritual literature produced during the period of Matthew’s authorship and the crafting of …

Case Study On A Shift To Open Educational Resources In An Academic Department, Karina May Jackson

Theses and Dissertations

Open educational resources (OER) have the potential to significantly impact the landscape of higher education. However, many users of OER find it difficult to adopt programmatically due to the barriers of awareness, quality assurance, institutional culture, and sustainability. This case study of the successful OER adoption in an education department serves as a look into the conditions and practices that allowed for the promotion, continued use, and production of open educational resources. The results indicate that the climate, technology, and opportunity costs surrounding tenure and promotion were key factors in the faculty's experience with acting on their inclinations toward openness.

Nonlinear Thomson Scattering In An Intense Tightly Focused Ultrashort Laser Pulse, Yance Sun

Theses and Dissertations

We investigate nonlinear Thomson scattering generated by intense laser pulses focused in noble gases. Electrons are ionized from low-density helium or argon early during the laser pulse and scatter light out the side of the focus. We measure fundamental, second, and third harmonic light focus over nearly the entire emission sphere. We investigate the influence of electron bunching, when individual atoms ionize multiple electrons sequentially as the laser field increases early during the laser pulse. Simulations suggest that correlation between electron positions for the ten electrons ionized from argon should distort the spatial pattern of nonlinear Thomson scattering relative to …

Cross-National Prevalence And Legality Of Consanguinity & Its Implications For State Security, Emma Dart

Undergraduate Honors Theses

This thesis examines the impact of cousin marriage prevalence on state stability and the development and behaviors of terrorist organizations, with a special focus on the destabilization of states through the power of kinship networks. Cousin marriage, often intertwined with other social practices such as patrilocality and polygyny, creates an isolated power structure that reinforces the fraternal structure present in kinship networks. The kinship network then uses the power gained through the trust in the community to undermine the legitimate rule of law. This research emphasizes the importance of understanding cousin marriage and its contribution to state stability and finds …
