Improving Restoration Success Of Winterfat: Influences Of Hydrophobic Seed Coatings And Planting Depth On Seedling Emergence, Kyle Andrew Cook

Theses and Dissertations

In western North America, winterfat (Krascheninnikovia lanata (Pursh) A. Meeuse & Smit) is a valuable protein-rich subshrub whose restoration has been limited by poor seed flowability and low rates of seedling establishment. Seed flowability can be limited by a dense covering of hairs on winterfat fruits that can cause them to clog in mechanized equipment. Seedling establishment can be limited by premature germination of fall-sown seeds that can cause over-winter seedling mortality from freezing, pathogen attack, and winter drought. Seed coatings may provide a way to overcome both of these barriers to winterfat restoration. Coatings can compress hairs against the …

The Effects Of An Oral Narrative And Expository School-Age Language Intervention: A Low-Dosage Study, Giana H. Hunsaker

Purpose: This study is Phase One of a multi-phase research initiative. The purpose of this study was to examine how well a low-dose, dual oral narrative and expository language intervention delivered in a small group setting improved expressive and receptive oral narrative and expository language in kindergarten, first grade, and second grade students who have been identified as having language disorder or emerging English academic language. Method: We administered a dynamic assessment of language to 325 kindergarten, first, and second grade students from two elementary schools in two school districts. The results of the dynamic assessment identified 61 students who …

Evaluating Parameter Uncertainty In Transportation Demand Models, Natalie Mae Gray

Theses and Dissertations

The inherent uncertainty in travel forecasting models -- arising from errors in input data, parameter estimation, or model formulation -- is receiving increasing attention from the scholarly and practicing community. In this research, we investigate the variance in forecasted traffic volumes resulting from varying the mode and destination choice parameters in an advanced trip-based travel demand model. Using Latin hypercube sampling to construct several hundred combinations of parameters across the plausible parameter space, we introduce substantial changes to mode and destination choice logsums and probabilities. However, the aggregate effects of of these changes on forecasted traffic volumes is small, with …

Instructional Psychology and Technology Graduate Student Projects

Graphite recently experienced four times the growth in a single quarter as the company has experienced in an entire year. Future growth projections are even higher, and the need for more rapid and effective onboarding is abundantly clear—our growth will outpace our ability to train and hire new employees and therefore slow down business.

This project provided new employees with an onboarding program consisting of eight learning modules.

Know Better, Do Better?: Parental Financial Socialization's Indirect Association With Couple Financial Communication Through Financial Self-Efficacy, Rachel M. Okamoto

Theses and Dissertations

Emerging adults find themselves in a time of great transition, especially related to finances and relationships. This study used a sample of 1,950 U.S. emerging adults currently in romantic relationships to investigate the role that parent financial socialization plays in the financial communication for emerging adult couples. This study also investigated if financial self-efficacy, in part, explained this association. Parent financial socialization was found to be positively associated with couple financial communication. In addition, financial self-efficacy was found to partially mediate this relationship. Individuals whose parents taught them effectively regarding finances had higher levels of self-efficacy regarding finances and had …

Semantic Memory And Decision-Making: An Fmri Study Regarding Covid-19 Vaccine Misinformation, Morgan Chase

Undergraduate Honors Theses

With the continued use and prevalence of social media, misinformation is likewise becoming more prevalent. Information about the COVID-19 pandemic was an example of the way misinformation spreads and presents challenges to society through polarization and discord. As people made decisions regarding whether to receive the COVID-19 vaccine, misinformation may have impacted their decision making. The goal of this study was to understand how misinformation and corrections to misinformation differentially activate the brain, in contrast to how correct information activates the brain, and how misinformation impacts decision making.

Interpreting Communally: How Service Learning Impacts Interpreting Proficiency, Breanna Michele Jones

Theses and Dissertations

Experiential learning programs, such as service learning, help students in Spanish medical interpreting classes to increase their interpreting proficiency, which includes their cultural understanding, linguistic performance, and professionalization (Rudvin & Tomassini, 2011). Currently, the Spanish Medical Interpretation class at Brigham Young University uses a community service-learning project in which students volunteer six hours of their time interpreting within the community. While largely beneficial, not all community partners offer the same learning opportunities. Some include training and shadowing programs, while others do not. This thesis seeks to determine the impact that shadowing opportunities and community partnerships have on interpreting proficiency and …

Behavioral And Physiologic Relationships Between Sensory Processing, Attention, And Prediction In Autistic Children: An Eye Tracking Study, Courtney Hunter

Theses and Dissertations

Autism spectrum disorder (ASD) prevalence has risen to one out of every 36 children born in the United States being diagnosed. Many individuals diagnosed experience sensory processing difficulties that make life challenging for them and their caregivers. However, there is no clear consensus on why sensory processing issues occur. Previous research has linked attention function to atypical sensory processing. Our study aimed to understand potential underlying mechanisms and correlates of this relationship. We theorized that prediction is a key contributing factor to how attention and sensory processing interact. The purpose of this study was to examine the relationship between sensory …

Hamiltonian Monte Carlo For Reconstructing Historical Earthquake-Induced Tsunamis, Jacob Paul Callahan

Theses and Dissertations

In many areas of the world, seismic hazards pose a great risk to both human and natural populations. In particular, earthquake-induced tsunamis are especially dangerous to many areas in the Pacific. The study and quantification of these seismic events can both help scientists better understand how these natural hazards occur and help at-risk populations make better preparations for these events. However, many events of interest occurred too long ago to be recorded by modern instruments, so data on these earthquakes are sparse and unreliable. To remedy this, a Bayesian method for reconstructing the source earthquakes for these historical tsunamis based …

Emotion, Sensory Processing, And Prosody In Neurotypical And Autistic Young Adults, Annika Henderson

Theses and Dissertations

There is a paucity of research regarding autistic adults, yet as autistic individuals grow to adulthood, they are often met with several barriers because of their differences from the neurotypical (NT) population. Given the demands of adult social interaction, some of the social difficulties experienced by autistic adults are likely related to emotion processing and prosody function. With sensory processing differences added as a diagnostic criterion for autism within the last decade, an investigation into its relationship with emotional processing, another marked difficulty for this population, is warranted. There are logical connections between sensory processing, emotion, and prosody, such that …

The film is a personal reflection of Norma’s experience with the Quechua language, a historically marginalized and currently endangered language. Her reflections are framed within the context of Cusco’s …

The Impact Of Growth Mindset Training On Entrepreneurial Action Among Necessity Entrepreneurs: Evidence From A Randomized Control Trial, Shad Morris, W. Chad Carlos, Geoffrey Kistruck, Robert Lount, Tumsify Elly Thomas

Faculty Publications

Although entrepreneurship training programs are designed to help necessity entrepreneurs acquire skills and capabilities to take entrepreneurial action, participants in these programs often fail to do so. In partnership with a local government agency, we conducted a randomized field experiment involving 165 entrepreneurs in rural Tanzania where in addition to providing technical-skills training, approximately half of the participants also received ‘growth mindset’ psychological training. Those who received the growth mindset training displayed more entrepreneurial action in their business than those in the control group. Importantly, higher levels of entrepreneurial self efficacy mediated the positive impact on entrepreneurial action displayed by …

Design Of A Transparent Cryogenic Silicon Carbide Probe Card With Tungsten Probe Tips, Ryan Beazer

Theses and Dissertations

DoD EO/IR applications continue to push imaging technology. Next generation advances require new material systems, novel device structures, as well as the improvement and development of read out integrated circuits. The common methodology used to assess devices and materials is to process test chip structures and focal plane arrays. Test chips have advantages over focal plane arrays; such as, variable area and stand alone devices and can be measured as a function of bias and temperature; however, focal plane arrays are the heart of the imager, but are measured through the read out integrated circuits, which can add complexity to …

Bringing The Analysis Of Electrodeposition Signals In Voltammetry Out Of The Shadows, Devin Rappleye, Ranon G. Fuller

Faculty Publications

Voltammetry studies of electrodeposition are growing rapidly. Yet, relations for the analysis of electrodeposition reactions in voltammetry remain relatively obscure in the literature. The existing cyclic and square wave voltammetry relations for electrodeposition and their limitations are discussed to increase awareness. A retrospective analysis is performed to demonstrate the impact of model selection in improving the analysis of electrodeposition behavior with voltammetric data. A repository for voltammetry models of electrodeposition is proposed to further increase familiarity and application of the most appropriate models, which would support a rapidly growing area of research and technological development.

Sex-Specific Variation In Deep Brain Shape Is Attenuated In Schizophrenia - An Enigma Consortium Meta-Analysis, Delaina Brooke Cimmino

Theses and Dissertations

Schizophrenia (SCZ) is characterized by a disconnect from reality that manifests as various clinical and cognitive symptoms, as well as consistent neurobiological abnormalities. However, unique sex-related differences have been observed regarding clinical presentation that imply separate brain substrates. The present study characterized deep-brain morphology using shape features to understand whether the neurobiology of schizophrenia varies as a function of sex. This study analyzed multi-site archival data from 1,579 male (M) and 836 female (F) participants with SCZ, as well as 1,934 male and 1,828 female healthy controls (CON) from twenty-four cross-sectional study samples from the ENIGMA Schizophrenia Workgroup. Harmonized shape …

Validating A Predictive Early Kindergarten Dynamic Assessment Of Word Level Reading And Language, Taylor Jordan Cena

Theses and Dissertations

The purpose of this study was to examine the preliminary psychometrics to revisions to the decoding subtest of the Predictive Early Assessment of Reading and Language (PEARL) dynamic assessment and to further examine the predictive validity of the language subtest of the PEARL. Specific aims were to (a) determine if kindergarten students made gains on the PEARL decoding subtest from pretest to a delayed standard posttest and to a delayed novel posttest, indicating that floor effects were mitigated, (b) to examine if there was variance in the delayed standard posttest and novel posttest scores, (c) to determine if there was …

Comparison Of The Unweighted Log-Rank And Weighted Prentice-Modified Wilcoxon Tests With Left-Truncated Data, Ellen Wight

Undergraduate Honors Theses

In survival analysis, there is a potential interaction between left-truncated data and rank test procedures for the difference between two groups that has not yet been investigated in depth. This study explores the effect of left truncation on the absolute and relative performance of the unweighted log-rank test and the weighted Prentice modification of the Gehan-Wilcoxon test. Resulting power from simulation study replications revealed that while left truncation does not affect which test performs better overall, it does affect the relative difference between the tests. It significantly worsens the individual performance of the Prentice-modified test, likely because of left truncation …

The Enduring Influence Of Emerson's Ideas On American Management Literature From The Lens Of Dale Carnegie’S How To Win Friends And Influence People, Taylor M. Dalton

Undergraduate Honors Theses

This thesis considers how the essays of Ralph Waldo Emerson may be seen as an important precursor to Dale Carnegie’s How to Win Friends and Influence People. Through a side-by-side analysis of four key topics—creativity, intention, action, and the idea of a non-hierarchal society—it becomes clear that the independent and creative mindset envisioned by Emerson in essays like “Self-Reliance” and “The American Scholar” finds a full and practical expression in the pages of Carnegie’s famous book. A close reading of these texts will reveal how Carnegie’s application of the philosophical ideas put forth by Emerson served as the foundation …

The Effects Of Time Pressure On Speech Fluency In Aging Adults: Comparisons With Divided Attention, Caleb Henderson Sanford

Theses and Dissertations

This study investigated the impacts of dual task and time pressure conditions on the speech fluency of 60 neurotypical adults between the ages of 26 and 85. Participants retold short stories in baseline, time pressure, dual task, and combined dual task and time pressure conditions. Dependent variables included five measures of speech fluency: words per minute (WPM), fillers per verbalization, false starts and repetitions per verbalization, extended pauses per utterance, and speech naturalness. Each of these variables was compared between age groups of younger, older, and elderly adults and across conditions. Results reveal that time pressure causes speech rate to …

Group Therapeutic Relationships Codevelopment In Short-Term Therapy: A Conceptual Replication And Extension Of Lo Coco Et Al. (2019), Tate M. Paxton

Theses and Dissertations

Objective: The empirical study of member-group mutual influence in group therapy is an emerging area of study. However, few replications have tried to generalize prior findings related to mutual influence. The aim of this study is to conceptually replicate the longitudinal group actor-partner interdependence models (LGAPIM) employed by Lo Coco et al. (2019) measuring how mutual influence and other factors affect the codevelopment of the group therapeutic relationships. Method: 343 clients were included in this archival analysis. Group Questionnaire (GQ) main subscales, positive bond (PB), positive work (PW), and negative relationship (NR), were gathered from early, middle, and late timepoints. …

Switzerland’S Banished Children, Una Suseli O'Connell

Swiss American Historical Society Review

Over a one hundred year period a practice known as verdingen (indentured servitude) operated in Switzerland. Children were removed from their families and sent to work on farms. It is estimated that between 1860 and 1960, one hundred thousand children were verdingt in this way, a quarter of them in the Canton of Bern. Local parishes paid farmers a monthly allowance to provide disadvantaged children with board and lodging. Although some treated their charges well, countless children suffered terrible hardship over many years. A veil of silence fell across entire communities as clergy, social workers and villagers chose to ignore …

Challenges To Swiss Democracy: Neutrality, Napoleon, & Nationalism, Thomas Quinn Marabello

Swiss American Historical Society Review

The year 1291 is considered the birth of Switzerland as we know it. Yet this is not entirely correct, since it was when the Swiss Confederacy was formed. This defensive alliance between some cantons that would expand over time did not mean Switzerland was a unified nation-state. Most of Europe in 1291 was stuck in the Middle Ages with few unified nations existing at the time. 1648 was an important year for Switzerland and the rest of Europe. The Treaty of Westphalia marked the end of the Thirty Years’ War that involved most of the continent over religion and politics. …

Literature As An "Affective Magnet": Defining, Engaging And Investigating Emotions In A (Russian) Language-Literature Classroom, Sofya Yunusova

Russian Language Journal

The purpose of this article is to conceptualize affective processes in reading literature in a foreign language. While generations of scholars and methodologists have stressed the educational potential of literary texts in terms of engaging learners’ emotions, the field has a relatively poor research base for discussing what these reading-induced emotions are and how to systematically promote them in a language-literature classroom. To this end, the current study first conceptualizes the different types of emotions that are arguably involved in reading literature in a foreign language and then formulates a set of pedagogical principles to foster their emergence in a …

Russian L2 Learners' And Teachers' Perceptions Of Learning Affordances, Marina Tsylina, Jose Luis Garrido Rivera, Hadis Ghaedi

Russian Language Journal

The environment offers a variety of resources for language learning and teaching. However, students and teachers might not recognize the same affordances or may perceive them differently. The mismatch between instructors’ and learners’ perceived affordances may result in ineffective use of time for both students and teachers, lower student motivation, and retard the language learning process. The study draws on the ecological approach (van Lier, 2000) to second language acquisition to investigate L2 Russian learners’ and teachers’ perceptions of language learning affordances, i.e., any physical objects, online materials, humans, and other resources which are embedded in the environment, and emerge …

L2 Writing As A Tool For Improving L2 Speaking Accuracy Through Text-Reconstruction Tasks In A Communicative Language Classroom, Natalia Sletova

Russian Language Journal

This study’s objective was to attract researchers’ attention to the potential role second language (L2) writing can play in improving L2 speaking grammatical accuracy in a communicative language classroom. Twenty-three beginner, twenty-one intermediate, and twenty advanced English learners of Russian completed a ‘noticing the gap’ activity using a text-reconstruction task in both written and spoken modalities, followed by a second text-reconstruction only in the spoken mode. The responses were measured for syntactic and semantic accuracy and complexity. The results indicated that lexical diversity and semantic complexity of produced output significantly improved with each level of proficiency in both written and …

Adolescent's Perceptions Of The Parent's Marital Relationship And The Impact On Their Suicide Risk, Savannah Heaton Hurt

Theses and Dissertations

Suicide risk is rapidly increasing in children and adolescents. It is vital that research explores the causes in child and adolescent suicide risk. Research has failed to identify if the marital relationship may be correlated with this increase in suicide ideation in children. This study set out to determine if a child's perception of their parents' marital conflict impacts the child's suicidal risk. Using the Family Foundations of Youth Development project this study analyzed 1,692 parent and child participants to test if the child's perceptions of the marital conflict impacted their suicide risk and if the parent's own report of …

The Ideal Spanish Candidate: The Effects Of Gender On The Electability Of Religious Candidates, Arabella Smith

Undergraduate Honors Theses

While the existing literature illustrates that voters living in Western countries are likely to elect female candidates and less likely to elect minority non-Christian candidates, literature has not yet addressed how the intersectionality of gender and religion affect voter preference. In this paper, I investigate how a candidate’s gender and religion interact to affect their likelihood of being elected. I use vignettes in a conjoint survey experiment of Spanish voters to show voter preference across two intersecting identities: gender and religion. I find that female Muslim candidates are significantly more electable than male Muslim candidates. This contributes to the body …

The Everydayness Of Instructional Design And The Pursuit Of Quality In Online Courses, Jason K. Mcdonald

Faculty Publications

This article reports research into the everydayness of instructional design (meaning designers’ daily routines, run-of-the-mill interactions with colleagues, and other, prosaic forms of social contact), and how everydayness relates to their pursuit of quality in online course design. These issues were investigated through an ethnographic case study, centered on a team of instructional designers at a university in the United States. Designers were observed spending significant amounts of time engaged in practices of course refinement, meaning mundane, workaday tasks like revising, updating, fine-tuning, or fixing the courses to which they were assigned. Refining practices were interrelated with, but also experienced …
