Do Poor Countries Catch Up To Rich Countries? Structural Change In The World-Economy, 1816-1916, Jared Walker

All Graduate Theses and Dissertations, Fall 2023 to Present

Do poor countries catch up to rich countries? To answer that question, countries were divided into upper class (core), middle class (semi-periphery), and lower class (periphery) based on degree of industrialization as indicated by primary energy consumption data. Findings indicated twenty-three upward transitions and five downward transitions during the period examined. Asymmetrical upward mobility was understood in the context of geographic expansion of the system. This sufficiently increased the population of the lower class (periphery) to support larger populations in the middle class (semi-periphery) and upper class (core). Nevertheless, probability analysis indicated a stable system characterized by high levels of …

Nutrient Management Of Cannabis In Controlled Environments, Julie A. Hershkowitz

All Graduate Theses and Dissertations, Fall 2023 to Present

Cannabis has been cultivated for millennia as a multipurpose crop for food, fiber, and medicine. Secondary metabolites called cannabinoids, including cannabidiol (CBD) and the psychoactive Δ-9 tetrahydrocannabinol (Δ-9 THC), are responsible for the medicinal properties of cannabis. The intoxicating nature of THC resulted in legislation prohibiting the possession and production of cannabis within the United States during the 20^th century. As a result, research programs on cannabis production were halted at most institutions. In recent years, cannabis production has become widespread within the US as a result of increasing legalization. However, modern cannabis production nutrient management programs often include …

“Get Tough!”: A Case Study On The Development Of The Sport Ethic In Youth Lacrosse, Ross Budziszewski

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

While participation in youth sport is often linked with positive psychosocial and physical outcomes (Holt et al., 2017), this context can also cultivate ideals that lead to the development of unethical beliefs as well as unsafe sport practices (Al-Yaarbi & Kavussanu, 2017). The sport ethic is described as the deviant overconformity by an athlete to fit societal expectations of a sport’s high-performance culture (Hughes & Coakley, 1991). Strong beliefs in the sport ethic can lead to moral disengagement, antisocial behavior, and viewing sport like warfare (Shields, Funk, & Bredemeier, 2015). Although the sport ethic has been examined in competitive adult …

An Examination Of Entrainment In Typically Developing Children, Kiersten A. Pope

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Purpose: Conversational entrainment describes the tendency for individuals to align their behavior with their communication partners and is essential for successful interaction. Evidence of entrainment in adults is robust, yet research regarding its development is sparse. Here, we investigate the effectiveness of a quasi-conversational paradigm for the purpose of identifying the speech rate entrainment abilities of children.

Method: Data were collected from a total of 50 typically developing children from 5-14 years old. Participants completed an entrainment task to identify the presence of speech rate modification depending on the presence of “fast” or “slow” stimuli. The entrainment task utilized a …

Identifying And Assessing Conflicts Between Future Development And Current Migratory Bird Habitat Around Farmington Bay, Utah, Aubin A. Douglas

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Every year, the Great Salt Lake (GSL) and its associated wetlands provide critical habitat for over 250 migratory bird species from both the Pacific and Central Flyways. The GSL borders the Wasatch Front, which is the fastest growing and most populous region in Utah. To support the ever-increasing working population, the government of Utah aspires to increase the robust economic growth of the region through economic incentives and development of infrastructure. As this area continues to develop, greater pressure will be placed on the surrounding natural resources, including the GSL, its wetlands, and the open space and agricultural land that …

Development Of An Animal Model For Enterovirus For Evaluation D68 For Screening Of Antiviral Therapies, W. Joseph Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Enterovirus D68 (EV-D68) virus has become more prevalent over the last 15 to 20 years. EV-D68 attacks the respiratory system and can cause severe disease in individuals who have underlying respiratory problems. There have also been reports of individuals with EV-D68 showing signs of neurological system problems and acute flaccid paralysis. Because of the increase in patients with EV-D68 and also the potential for neurological disease, an animal model is needed to study the disease and to evaluate experimental therapies for EV-D68 infection.

To develop the animal model, 4-week old AG129 mice that lack alpha and beta interferon receptors, making …

Community Wildfire Planning And Design: A Review And Evaluation Of Current Policies And Practices In The Western United States, Carlene C. Klein

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wildland fire is an important and complex issue, particularly in the fire-prone ecosystems of the Western United States. At the same time that the number of catastrophic wildland fires is increasing across the United States, more people are moving in to wildland areas growing the interface between urban and wildlands. Managing wildfire in the Western United States is becoming increasingly more complex and costly as growth and development continues to push the edge of municipalities into undeveloped wildlands. Communities in this wildland urban interface are exacerbating the problem of wildfire in the West.

With more people living in wildfire prone …

The Development Of English Learners As Writers Of Opinion Pieces, Auri Ann Squire

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The population of English learners (ELs) is growing rapidly across the U.S. Concurrently, elementary students throughout the country are being required to produce more sophisticated writing products than ever before as a result of the heavy emphasis on writing instruction in the recently adopted Common Core State Standards. This qualitative study examined how to best support ELs as they develop as writers. It also addressed the strong need to investigate the impact of students discussing ideas with a partner throughout the writing process.

In order to determine how ELs develop as writers, a multiple case study was conducted in a …

Language Brokering Consequences As A Function Of Development, Brent M. Gage

Undergraduate Honors Capstone Projects

Language brokering can be defined as a child mediating linguistically for a parent or other adult figure, either in spoken or written communication. This situation is a common occurrence among migrant and refugee families as children tend to acquire a new language at an accelerated rate in comparison with adults. As the immigrant and refugee populations continue to grow in comparison with native groups within the United States, it is increasingly important to understand the phenomenon of child language brokering. Moreover, it is particularly relevant to understand how the expectations for and consequences of language brokering may help to shape …

Adoption, Adaptation, And Abandonment: Appropriation Of Science Education Professional Development Learning, Max L. Longhurst

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Understanding factors that influence teachers to use certain practices from training they receive will help improve learning experiences for students. This study examined how two teachers with the same teacher training experience use learning from that training in their instruction differently. This research attempted to account for multiple factors that influenced teachers learning. Educator’s incorporation of teaching practices can vary from teacher to teacher and from training to training. This variability is understood in terms of their appropriation of new teaching practices into their teaching and delivery of learning. Two teachers were selected as a result of their participation in …

Framing Fracking: Media Coverage Of Unconventional Oil And Gas Development In South Texas, Jebadiha E. Potterf

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The rapid growth of unconventional oil and gas development in the United States has greatly increased the production of these minerals, but has also raised the public’s concern over the dangers involved in this process. Due to the contested nature of unconventional development gaining an understanding of both how the public perceives this development and the influences on these perceptions is vital. As several previous research studies have investigated public perceptions this project addresses the second of these requirements.

This is done using qualitative methods to analyze the content of the online communications of proponents and opponents of this development. …

Development And Validation Of An Instrument To Measure Participant Engagement In State-Federal Vocational Rehabilitation Programs, Joshua D. Southwick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Rehabilitation Act of 1973, as amended, calls for participants to become “active and full partners in the vocational rehabilitation process.” This study represents the first research to specifically address the actual meaning and importance of participant engagement in the state-federal Vocational Rehabilitation program. Defining the construct of participant engagement is an important first step in creating more effective services for persons with disabilities. It was proposed that engagement in vocational rehabilitation would include three factors: (a) attendance at meetings with the counselor, (b) fulfillment of an expected contribution during meetings, and (c) completion of homework tasks between meetings. Through …

Development Of A Coupled Fluid And Colloidall Particle Transport Model, Scott Ripplinger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A colloidal system usually refers to when very small particles are suspended within a solution. The study of these systems encompasses a variety of cases including bacteria in ground water, blood cells and platelets in blood plasma, and river silt transport. Taking a look at these kinds of systems using computer simulation can provide a great deal of insight into how they work. Most approaches to date do not look at the details of the system, however, and are specific to given system. In this study a program called OpenFOAM is used as a basis to build a computer simulation …

Development Of Standards, Objectives, And Curriculum Guide To Teach Basic Electronics For Utah Science Credit In Secondary School Education, Rick Pierce

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Recently, the Utah State Office of Education (USOE) has accepted Basic Electronics, Classification of Instructional Programs (CIP) code 47.0105, as an elective to fill the required third science credit for secondary education (grades 10-12) students. The current Utah state core standards and objectives used for curriculum development in the Basic Electronics classes are now inadequate, as they are more than 15 years old, and designed specifically for students pursuing a technical career path. A formatting change to the document was implemented in 2008, but the standards and objectives were not changed.
Students are subsequently being taught the fundamentals of technology …

Evaluation Of Survey Methods And Development Of Species Distribution Models For Kit Foxes In The Great Basin Desert, Stephen J. Dempsey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Historically, kit foxes (Vulpes macrotis) once occupied the desert and semi-arid regions of southwestern North America, ranging from Idaho to central Mexico. Their range-wide decline has warranted the kit fox to be designated as a state sensitive species in Utah. Once considered the most abundant carnivore in western Utah, the kit fox has been in steep decline over the past decade, creating a demand to determine kit fox presence in the Great Basin desert. Currently there is little consensus on which survey methodology is best for detecting kit fox presence. We tested 4 survey methods (scat deposition, scent …

Cationic Starch Synthesis, Development, And Evaluation For Harvesting Microalgae For Wastewater Treatment, Renil John Anthony

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Microalgae are the preferred crop for the production of biodiesel. Microalgae are microplants that have the ability to harness sunlight more efficiently than other plants and store 20-80% lipids per g of dry algae in their cells. Microalgae have the extraordinary ability to grow in brackish water or wastewater. Microalgae can be grown in municipal wastewater to uptake phosphorus and nitrogen and remediate the wastewater of these nutrients. Microalgae thus cultivated accomplishes a dual role of wastewater treatment and provides a sustainable feedstock for biofuels and other bioproducts.

This study focused on efficiently harvesting microalgae from water using modified starch. …

Nutritional And Economic Analysis Of Small-Scale Agriculture In Imbabura, Ecuador, Jake Erickson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Intervention projects in the developing world normally aim to satisfy either the nutritional needs of a group, or advancing the economic stability, but not both. One of the many issues that may arise by narrowly focusing and creating an aid program is that although a group may be fed, they are not equipped to mitigate risks that will arise after project completion and thus continue or revert back to a malnourished state. A bridge is required to join the economic and nutritional programs to create aid interventions that are sustainable past the point of donor separation.

This paper proposes the …

Narrative Development In Preschool And School-Age Children, Sara Hegsted

Undergraduate Honors Capstone Projects

Children hear and use narratives in a variety of contexts including school, social situations, and at home. A narrative is a form of discourse that is used to tell the listener what happened in a temporally sequenced, agent-focused way, and these stories can be a production of a real or fictional account. Speech language pathologists take a particular interest in children's narrative abilities because children's story telling capabilities play a large role in language acquisition as well as future academic success, especially literacy. The following literature review seeks to synthesize information on narrative development, production, and intervention from the perspective …

Development Of Methods For Assessing The Effect Of Moisture And Aging On Sliceability Of Cheese, Jess Perrie

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Sliceability is a cheese’s ability to cut cleanly into thin slices, resist breakage or fracture at slices edges, and undergo a high level of bending before breaking. Intuitively, sliceability depends on the chemistry, microstructural, and rheological properties of the casein network. Currently there is no reported scientific research investigating evaluation methods of cheese slice quality, as well as properties that influence a cheese’s ability to slice.

In this study, a method for slice quality evaluation was developed on purchased cheese and performed on commercial cheeses and experimental cheeses manufactured at three different moisture contents (40.6%, 37.0%, and 33.9%). In addition, …

Development Of Assessment Strategies For Sign Retroreflectivity, Travis L. Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Manual on Uniform Traffic Control Devices (MUTCD) now specifies minimum retroreflectivity requirements. These requirements include an obligation for agencies to develop a strategy for maintaining compliance. With budget considerations, it is important that transportation agencies be able to efficiently assess the performance of their assets and adopt management strategies to comply with such requirements. As a foundational work, this research develops specific methodology for assessing the condition and performance of sign assets that are maintained by a large transportation agency. In doing so, this research provides for the determination of key elements that should be considered when developing any …

Father-Child Interactions At 24 And 36 Months And Developmental Outcomes At Prekindergarten, Shareesa L. Mcmurdie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study looked at father teaching interactions and singing in toddlerhood as predictors of child cognitive and language outcomes at prekindergarten in a low-income, ethnically diverse sample. Results found that, overall, father teaching interactions in toddlerhood predicted child cognitive and language outcomes at prekindergarten and father singing in toddlerhood predicted language outcomes. Fathers provided slightly more teaching interactions at child age 24 months than at 36 months, and sang more frequently at 36 months.

Within ethnic groups, father teaching interactions were statistically significant in predicting cognitive and language development outcomes for children of African American (approached significance for language outcomes) …

The Intersection Of Multiple Oppressed Identities: Implications For Identity Development, Angela Marie Enno

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Understanding the experiences and identity development of ethnic minority LGBTQ (lesbian, gay, bisexual, transgender and queer or questioning) individuals presents a challenge because the theories of identity development that exist to date may not take into account their unique perspectives. Theories of identity development that are not specific to ethnic minority or LGBTQ identities may not represent their experiences well. At the same time, theories of ethnic identity development may not fit for individuals who are LGBTQ; and theories of LGBTQ identity development may not fit for ethnic minorities. No theory of identity development to date takes into account all …

Cultural Compatibility: Economic Development In Eastern Europe, Daniel Brilliant

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The objective of Daniel Brilliant’s research is to explore the relationship between culture and economic prosperity in the former communist countries of Eastern Europe. Learning why some of these countries do better than others is of interest in discovering what causes a country’s economy to grow in general. Knowing the causes of economic growth helps in determining what policies, if any, can be adopted by a country to help promote economic growth. Some have theorized that government policies are at the heart of prosperity. Others have speculated that cultural factors play a large role in determining if such policies will …

Successfully Incorporating The Participant Perspective: Analysis Of Participatory Research In Development, Zachary T. Revene

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Literature from recent decades has highlighted the importance of incorporating the perspective of communities into development project planning and implementation. In this project, the participant perspective was documented through qualitative ethnographic techniques and illustrates the different ways in which this perspective was either included or excluded in two separate case studies along the northern coast of Peru. The case study of huachaque farmers surrounding the UNESCO World Heritage Site of Chan Chan provided an example of the general failure to incorporate the participant perspective into planning of future biodiversity conservation projects. The case study of Huaca Chotuna provided an example …

An Ethnographic Study Of In-Service And Pre-Service Teacher Collaboration In The Development And Execution Of Mathematics Lessons, Jessica Munns

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

While much is known about effective strategies for teaching mathematics, less is understood about how to lead new teachers to employ research-based practices in their work. To address this issue we followed a Methods of Teaching Secondary and Middle School Mathematics course at Utah State University where collaboration between inservice and pre-service teachers was emphasized. This report documents examples of the implementation of research-based teaching practices by collaborative groups during the course. The structure of collaboration followed a lesson study model involving research and planning, execution and observation, and reflection and revision of lessons. Preservice and in-service teachers met twice …

Development And Implementation Of A Bayesian Model For Sediment Transport In Fluvial Systems, Mark Schmelter

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Recent studies in the field of fluvial sediment transport underscore the difficulty in reliably estimating transport model parameters, collecting accurate observations, and making predictions due to measurement error and conceptual model uncertainty. There is a pressing need to develop models that can account for measurement error, conceptual model uncertainty, and natural variability while providing probability-based predictions as well as a means for conceptual model discrimination. The model presented in this research employs an excess shear sediment transport equation for a uni-size sediment bed developed in a Bayesian statistical framework. This statistical model provides a means to rigorously estimate distributions of …

Comparative Studies On Oxygen Mass Transfer For The Design And Development Of A Single-Use Fermentor, Kristan L. Sorenson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Accurate experimental oxygen mass transfer coefficient, a measure of how quickly oxygen travels from a gas bubble to the bulk liquid, is important for comparing performance and for evaluating the oxygen transfer capability of a fermentor. Delays in probe response and changing gas volumes upon start-up of gassing affect the accuracy of oxygen transfer measurements. To mitigate these inaccuracies, a standard correction procedure for oxygen mass transfer data was established for highly oxygenated, well-mixed fermentation systems. Probe response time correction was generated by applying a second-order response model to dissolved oxygen probes and shown to be effective within 4%. By …

Cell Phone Use And Psychosocial Development Among Emerging Adults, Torrey B. Morrill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The cell phone has rapidly become an integral, and, for some, an essential communication tool that is being used worldwide. With cell phone ownership becoming so widespread, especially among the younger generation, society is starting to see and question the impacts of cell phone use on adolescent development.

Relations between cell phone possession, cell phone use, and psychosocial and identity development were investigated using Erikson's Psychosocial Theory and Marcia's Adolescent Identity Paradigm. A sample of 705 college students, ages 18-24, completed a questionnaire that measured the amount and type of cell phone use, identity development (Extended Objective Measure of Ego …

Phenotypic Plasticity And The Post-Modern Synthesis: Integrating Evo-Devo And Quantitative Genetics In Theoretical And Empirical Studies, Alison G. Scoville

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mainstream evolutionary biology lacks a mature theory of phenotype. Following from the Modern Synthesis, researchers tend to assume an unrealistically simple mapping of genotype to phenotype, or else trust that the complexities of developmental architecture can be adequately captured by measuring trait variances and covariances. In contrast, the growing field of evolutionary developmental biology (evo-devo) explicitly examines the relationship between developmental architecture and evolutionary change, but lacks a rigorous quantitative and predictive framework. In my dissertation, I strive to integrate quantitative genetics and evo-devo, using both theoretical and empirical studies of plasticity. My first paper explores the effect of realistic …
