Modeling Subglottic Stenosis Effects On Phonation Threshold Flow In The Porcine Larynx, Robin Michelle Smith

Theses and Dissertations

Subglottic stenosis (SGS) is an abnormal narrowing of the airway at the level of the cricoid cartilage, above the first tracheal ring and immediately beneath the vocal folds. Individuals with SGS experience a reduction in their ability to breathe as well as adverse effects on voice function. SGS can result from a variety of causes with the type of treatment depending on stenosis severity. Surgical techniques such as laryngotracheal and cricotracheal reconstruction are beneficial for airway maintenance; however, these procedures have resulted in negative effects on voice production. On the other hand, there are patients with SGS who do not …

A Discourse Analysis Of Clinician-Child Interactions Within A Meaning-Based Phonological Intervention, Brittany Appleby Long

Theses and Dissertations

This qualitative study analyzed interactions between clinicians and a male child, aged 5 years 9 months old, with significant phonological as well as language deficits within a meaning-based phonological intervention implemented over a nine-month period. Play-based intervention strategies were presented in activities that varied in communicative complexity. The clinician, along with graduate-student assistants, frequently modeled and elicited target word productions as they interacted with the child in routines and scripted play contexts. Transcriptions of interactions were analyzed using a conversational analysis that explored engagement and participation, turn taking, and linguistic complexity of utterances produced in adjacent turns. The analyses illustrated …

Spanish For Lunch: Engaging Young Interpreters In Teacher Professional Development, Kevin Landon Johnstun

Theses and Dissertations

Across the United States, schools are largely segregated by race and ethnicity, resulting in schools that are densely Latino and teaching staff who are overwhelming monolingual English speakers, as most teachers are white women. This has created difficulty in home communication in these schools. Given the positive impacts of personal and frequent home communication, a greater capacity of teachers to communicate with parents may be an important asset in school improvement efforts. This study looks at ongoing design-based research efforts to engage bilingual students in helping their teachers become more capable of communicating in Spanish. Through online-delivered challenges, teachers and …

Antibacterial And Antifungal Activity Of Ceragenins, Mimics Of Endogenous Antimicrobial Peptides, Marjan Mohammadihashemi

Theses and Dissertations

The continuous emergence of drug-resistance pathogens is a global concern. As a result, substantial effort is being expended to develop new therapeutics and mechanisms for controlling microbial growth to avoid entering a "post-antibiotic" era in which commonly used antibiotics are no longer effective in treating infections. In this work, we investigate the efficacy and application of ceragenins as non-peptide mimics of antimicrobial peptides (AMPs). First, this work examines the susceptibility of drug-resistant Gram-negative bacteria. The susceptibility of colistin-resistant clinical isolates of Klebsiella pneumoniae to ceragenins and AMPs suggests that there is little to no cross-resistance between colistin and ceragenins/AMPs. Furthermore, …

Impacts Of Novel Fire And Herbivory Regimes On Snow-Waterresources And Resilience Of Aspen Forests, Jordan Daniel Maxwell

Theses and Dissertations

Human activities and expansion have created novel disturbance patterns across Earth’s landscapes. Disturbance is an ecological interruption after which ecosystem recovery or transition into a new state can occur, affecting biodiversity, ecosystem functioning, and theavailability of ecosystem services. Fire and herbivory are two of the most widespread forces of disturbance which shape ecosystems globally. In temperate forest ecosystems, fire affects forest composition, which influences the diversity and resilience of ecosystems (chapters 1 and 2) and forest canopy structure, which is important to snowpack accumulation and the availability of water resources (chapters 3 and 4). In chapter one, the effects of …

Conversions, Arrests, And Friendships: A Story Of Two Icelandic Police Officers, Fred E. Woods, Kari Bjarnason

Religious Educator: Perspectives on the Restored Gospel

In 1881 in Reykjavík, Iceland, two Icelandic police officers, Þorsteinn (Thorsteinn) Jónsson and Jón Borgfirðingur, were sent to arrest Latter-day Saint missionaries. These missionaries had baptized the first three converts to The Church of Jesus Christ of Latter-day Saints in Reykjavík a year earlier, and one of those converts, Sigríður Jónsdóttir, happened to be the wife of one of the arresting officers. But a remarkable friendship, one that thrived irrespective of time, distance, and religious differences, developed due to the arrests and the events surrounding them. Although the story and historical context of the missionaries’ experience in Reykjavík have been …

The Bread Of Life, With Chocolate Chips, Samuel Morris Brown

BYU Studies

I learned to cook when my wife was recovering from cancer surgery. There’s a hollowness, kindred to cancer, hungry to swallow you up when a beloved’s life is threatened. I still remember, with a soul-deep ache, that time when her body was a battleground for scalpeling surgeons and monstrously mutated cells. Those harrowing days and their fulminating awareness of her mortality still haunts me. I’ve seen a lot of death in my short life; nothing disoriented me like her cancer.

Sensory Acceptability And Nutrient Stability In Micronutrient-Fortified Soymilk Prepared In Small-Scale Batch Processes, Dallin Max Hardy

Theses and Dissertations

Fortified and unfortified soymilk were produced from the same production batches for comparative evaluation. Fortification included a comprehensive array of micronutrients of interest to community and humanitarian nutrition programs. The effects of time after fortification prior to cooling, cooling method, and light or dark refrigerated storage on the stability of 5 vitamins (vitamin A, vitamin C, thiamine, riboflavin, and folate) were investigated for both fortified and unfortified soymilk. Significant vitamin C loss (6%) and mild vitamin A isomerization occurred while soymilk was hot immediately following fortification. Cooling bottled soymilk in an ambient water bath or ice water bath made no …

Space Use And Annual Survival Of Hybridized Mouflon Sheep In Hawaii And Comparing Estimates Of Population Size Through Instantaneous Sampling And Photographic Capture-Recapture, Bradley Jay Adams

Theses and Dissertations

Significant efforts in conservation are devoted to the management and study of ungulates, due to their significant roles in ecosystems as well as their potential economic value. This is especially true for species considered exotic, such as mouflon sheep (Ovis musimon) in Hawaii. Effective management of an exotic species requires an understanding of ecological metrics such as space use, survival, and population size. We provided these metrics for a population of mouflon that have hybridized with feral sheep (Ovis aries) on the island of Hawaii. In Chapter 1, we quantified space use and annual survival of sheep in an area …

“Chosen Instruments”: Tolkien’S Hobbits And The Rhetoric Of The Dispossessed, Samuel Bennett Watson

Theses and Dissertations

Tolkien’s hobbit characters are capable of a particular type of rhetorical persuasion, one which relies on their ability to leverage their status as outsiders among the other people of Middle-earth. The hobbits are uniquely suited to the task of bringing unity to Middle-earth’s people because of the simplicity of their rhetoric, which focuses on proving their own morality and presenting truths without elaboration. When compared with the text, the film adaptations of The Lord of the Rings also help highlight the importance that Tolkien placed on the simplicity of hobbit rhetoric. These abilities of the hobbits become clear through a …

Currently, a MoVNbTe oxide is the most promising catalyst but it …

Brazil And Bashō: Negotiating Japanese-Brazilian Hybrid Identity Through Mujōkan In Adriana Lisboa’S Rakushisha, Suzanne Noelle Shibuta

Theses and Dissertations

Hybrid identities occupy a unique space within the field of identity and culture. Due to the instability and transitory nature of hybrid identities, individuals who fall within the category of hybridity often struggle to recognize and accept their identities. Do such individuals identify with one culture, the other, neither, or both? Adriana Lisboa’s novel Rakushisha offers new insight into the realm of hybridity through the exploration of mujōkan, a uniquely Japanese awareness of impermanence that also helps to explain the cycle of suffering, continuity, and regeneration that Lisboa’s characters experience. Although hybrid identities by nature are unstable, constantly in motion …

In early winter 2018, two Douglas’s squirrels were observed and …

Notes On The Predation Of Rough-Footed Mud Turtles (Kinosternon Hirtipes) In West Texas, Usa, Steven G. Platt, Jennifer L. Smith, Thomas R. Rainwater, Wiebke J. Boeing

Western North American Naturalist

Little is known concerning predation of rough-footed mud turtles (Kinosternon hirtipes), a species of conservation concern in Texas, USA. During field studies conducted from 2007 to 2016, we documented 8 instances (1 juvenile, 2 males, and 5 females) of predation among individuals of one of the few (<10) remaining populations of K. hirtipes in Texas. Predation was attributed to raccoons (Procyon lotor; n = 5) and feral pigs (Sus scrofa; n = 2); the predator responsible for the death of one of the turtles could not be determined. Turtles are vulnerable to predation when exposed by low water levels …

Fight, Flight, And Freeze: Human Responses In A Business Strategy Environment, Michael Nixon

Student Works

Fight, flight, and freeze responses are a natural part of how we operate as humans. These responses permeate our lives and affect our decisions in major ways. This thesis first employs a case study to help the reader understand natural reaction processes, then analyzes case studies where businesses applied strategies that closely resembled these reaction processes. I then propose a framework to mimic physiological reaction processes to help companies arrive at the optimal solution.

On The Persecution Of The Salvadoran People, Jacob Newman

Undergraduate Honors Theses

El Salvador is the focal point of an American refugee crisis. This crisis owes its origins to protracted abuse and negligence suffered by the Salvadoran people. They are confronted with violence, apathy, and corruption in their homeland and throughout the international sphere. A complex system of harms has come to a concentrated fruition in the form of governments and gangs, histories and happenstance. The purpose of this thesis is, first, to document the persecution faced by Salvadorans and, second, argue that the conditions in El Salvador put many Salvadorans in need of asylum.

"Where Was I?": Linguistic Reprocessing In Distracted Reading, Katrina Hillam

Undergraduate Honors Theses

This thesis examines the impact of repeated auditory and task-oriented distractors on linguistic processing. Impact was measured through eye tracking software recording first fixation duration, gaze duration, and total time spent on distractor words. This study found consistent significant difference only in the total time category, suggesting that the processing stage most impacted by distraction is global context—our awareness of how a word fits in to the paragraph at large. Participants were skilled at regaining reading speed after distraction, showing no overall impairment for other processing levels. This phenomenon could be dangerous for student comprehension, as reading speed will be …

Лол—Comparing Expressions Of Humor Used In Memes By Russian And English Speakers, Teya Jensen

Undergraduate Honors Theses

This thesis explores trends in the types of humor used by Russian and English speakers in the creation and perpetuation of internet memes. The purpose of this project is to better understand the impact of the globalizing effects of the internet on social identity. Most current scholarship addressing the effects of memes on social communication and research into the specific trends of humor on the internet, focuses on the meme culture of English-speakers. Some researchers have focused on analyzing meme use in other countries, but they have not compared American and Russian humor.

This project demonstrates how patterns of pastiche, …

Legal Supremacy: The Translation Between Tsarist And Communist Constitutions And Criminal Codes, Jennifer Kimball

Undergraduate Honors Theses

This thesis examines the constitutions and criminal codes which appeared at the end of the Tsarist regime of Nicholas II and the beginning of the new regime of the Bolsheviks led by Vladimir Lenin. It contrasts the constitutions and criminal codes of each regime to demonstrate the changes between state ideologies and laws, but also highlight the similarities between the two in terms of their concerns for the state. It shows that despite the changes that occurred in the written law, each regime was primarily concerned with establishing the supremacy of the ruling government.

Computationally Modeling The Trophic Cascade In Yellowstone National Park, Emily Menden

Undergraduate Honors Theses

Many of the world’s ecosystems are facing species elimination (2). Whether this elimination is intentional or accidental, the consequences need to be understood in order to make better resource management decisions. Computational models can be helpful in making these management decisions. Yellowstone National Park gives ecologists a unique opportunity to study species elimination and reintroduction.

In the 1920s, wolves were extirpated from the Greater Yellowstone Area. The absence of wolves allowed the elk population to increase unbounded by a natural predator. Over the years, Yellowstone management took various measures to control the elk population. In the 1970s, the National Park …

The treatment group participated in 8 weeks of Story Champs intervention, the alternate-treatment group participated in 8 weeks of shared storybook intervention, and the no treatment group served as a control. Results indicated that oral narrative intervention delivered through a multi-tiered system of language support (MTSLS) causally impacted the oral language, reading comprehension, and narrative writing …

Wasatch Front Atmospheric Deposition Reflects Regional Desert Dust And Local Anthropogenic Sources, Michael Max Goodman

Theses and Dissertations

Dust originating from dry lakes contributes harmful and toxic elements to downwind urban areas and mountain snowpack that is compounded by local contaminant inputs from anthropogenic sources. To evaluate dust contributions to an urban area from regional playas, we sampled playa dust sources, urban dust deposition, and snow dust deposition in central Utah, USA. Samples were analyzed for grain size, mineralogy, and chemistry. Bulk mineralogy between playa, urban, and snow dust samples was similar, with silicate, carbonate, and evaporite minerals. Grain size distribution between fine playa, urban, and snow dust particles was also similar. Elements found at high concentrations in …

Annual Survival And Harvest Vulnerability Of Elk (Cervus Canadensis), Maksim Sergeyev

Theses and Dissertations

Across the western United States, most populations of Rocky Mountain elk (Cervus canadensis) are managed through hunter harvest (Sandrey 1983). In hunted populations, human harvest is the leading source of mortality (Ballard 2000). With the exception of elk in national parks, populations are primarily managed through hunter harvest. Other sources of mortality include disease, automobile collisions, and predation from mountain lions, coyotes, wolves, and black bears (Childress 2003, Hornocker 1970). As a species of management concern and high economic value (Pickton 2008), hunted populations of elk are carefully managed to target population sizes to guarantee a sustainable supply and ensure …

"Yup, So-Jeer": Interlanguage And Ruptured Translation In Charles Dickens's The Perils Of Certain English Prisoners, Jacob Kurt Nielsen

Theses and Dissertations

Co-authored by Charles Dickens and Wilkie Collins, The Perils of Certain English Prisoners is a tale of linguistic subversion in colonial spaces. Christian George King-a native "Sambo" that betrays the English colonists on Silver Store to a marauding band of pirates-demonstrates a linguistic phenomenon that scholars call interlanguage, or a quasi-language that partially resembles both English and his native language. Because of its status as a language between languages, King's interlanguage disrupts the linguistic hierarchy of the tale by opening possibilities for miscommunication. To combat this underlying tension, the colonists must rely on translation-specifically, on the mistaken belief that all …
