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 …

Preserved Motor Asymmetry In Late Adulthood: Is Measuring Chronological Age Enough?, Sydney Y. Schaefer

Kinesiology and Health Science Faculty Publications

When comparing motor performance of the dominant and nondominant hands, older adults tend to be less asymmetric compared to young adults. This has suggested decreased motor lateralization and functional compensation within the aging brain. The current study further addressed this question by testing whether motor asymmetry was reduced in a sample of 44 healthy right-handed adults ages 65-89. We hypothesized that the older the age, the less the motor asymmetry, and that ‘old old’ participants (age 80+) would have less motor asymmetry than ‘young old’ participants (age 65-79). Using two naturalistic tasks that selectively biased the dominant or nondominant hands, …

Effect Of Aggregation At A Winter Feeding Station On Intestinal Parasite Load In Elk (Cervus Canadensis), Morgan Jaromilla Hughes

Undergraduate Honors Capstone Projects

Winter feeding stations are used throughout the western US to reduce elk depredation of crops and haystacks on private lands. Many of the unintended effects of such artificial congregation remain unexamined, but generally, across species, locally increased host densities result in increased parasite loads. This adds physiological stress to individual animals and in game species such as elk it could reduce their value to sportsmen. Through laboratory analyses of fresh samples, we recorded nematode egg densities in elk feces collected during two periods ( early and late) in the supplementary feeding season. Mean nematode egg density remained fairly constant in …

Common Threads: An Examination Of Common Threads Of Design Value, Woven Together By Designers To Achieve Elevated Products Across Disciplines, Laura Taylor

Undergraduate Honors Capstone Projects

Though what defines good design is subject to personal opinion, some objectivity of good design in existing products is mutually and consistently recognized by design professionals, the business sector, and the consumer public. Despite the complexity of defining good design, there clearly exist measurable, objective, common threads of design value which create elevated designs, across disciplines, which are identifiable and accepted by those within and beyond design professions.

By first examining over 100 contemporary product designs and identifying measurable, objective commonalities which elevate them, this thesis then individually examines and outlines ten categories of common design values. Once these design …

Dna Methylation Analysis Of Lin28a & Hand1 In Electrostimulated Genetically Unmodified Porcine Fibroblast Cells Grown In Vitro, Sara E. Calicchia

Undergraduate Honors Capstone Projects

Pluripotent (undifferentiated) cells are important for their applications in regenerative medicine. However, gene-based nuclear reprogramming of adult somatic cells is a slow and inefficient process, and poses some risk to recipient patients. Therefore, a major goal within the field of stem cell biology is to find a way to accomplish adult somatic cell de-differentiation using small chemical modulators of gene expression or other non-genomic mechanisms. Pilot studies in our laboratory have suggested that cells exposed to silver ions generated by the passage of a weak electrical current through a silver wire show morphological and gene expression changes reminiscent of de-differentiation. …

Exploring The Relationship Between Utah's Wages And Utah's Real Estate Values, S. Scott Laneri

Undergraduate Honors Capstone Projects

This paper uses a variety of multiple regression analysis techniques to attempt to answer whether a direct relationship exists between Utah's employee wages and Utah's residential real estate values. Unexpected declines in real estate values can have seriously negative impacts on businesses, individuals, and local governments in Utah. Conversely, unexpected increases represent missed opportunities. Researchers have used various statistical and mathematical methods to explain or predict changes in real estate values, but no method has consistently predicted values for a long period of time or across multiple geographical areas. This paper focuses on exploring the relationship between variables in Utah …

Genetic And Environmental Interactions On Schizophrenia-Like Phenotypes In Chl1 Deficient Mice, J. Daniel Obray

Undergraduate Honors Capstone Projects

Schizophrenia is a debilitating disorder which is often characterized by dysregulation of the processing of sensory information. Schizophrenia has been shown to have a strong genetic component, as well as a strong environmental component. As such, a number of hypotheses such as the diathesis stress hypothesis have been developed to explain the etiology of schizophrenia. As most of these theories attempt to account for a genetic and an environmental factor, they are often viewed as double-hit models of schizophrenia. Several theories have emerged as potential explanations for the symptoms of schizophrenia. The dopamine hypothesis suggests that the basal level of …

Monitering And Addressing Light Pollution At Utah State University, Rachel Kim Nydegger

Undergraduate Honors Capstone Projects

Many outdoor light fixtures illuminate in all directions, meaning that a large portion of light is emitted upwards. This excess light - light pollution - represents wasted energy and money, decreases public safety, is a health hazard for humans as well as wildlife, and inhibits the view of the night sky. In order to quantify the anthropogenic contribution of local light pollution, I studied detection methods at the National Optical Astronomy Observatory though a summer REU in 2013. Upon my return to USU, I monitored the night sky brightness from September 2013 to April 2015 at Utah State University. Due …

Quantifying Non-Game Fish Sampling Biases And Demographics To Better Understand The Role Of Fish In Pelican Diet And Distribution At Strawberry Reservoir, Ut, Jamie Reynolds

Undergraduate Honors Capstone Projects

Predation and competition are natural ecological processes, though these interactions occasionally cause concern among humans when ecosystem services are involved (e.g., popular fisheries in highly managed systems). The population of American white pelican (Pelecanus erythrorhynchos) at Strawberry Reservoir (Utah) has increased dramatically in the last decade, as have the populations of Utah sucker (Catostomus ardens) and Utah chub (Gila atraria). Anglers and managers are concerned that predation by pelicans and competition from non-game fish species are negatively impacting the reservoir's prized Bonneville cutthroat trout (Oncorhynchus clarkii utah) fishery. My project focused on …

The Effects Of Zno Nanoparticles On Egg, Larva, And Adult Rough-Skinned Newts (Taricha Granulosa), Austin Reid Spence

Undergraduate Honors Capstone Projects

The objective of this study was to examine the effects of zinc oxide (ZnO) nanoparticles on egg, larva, and adult rough-skinned newts, Taricha granulosa. To date, little research has been done to investigate the potentially detrimental effects of nanoparticles on amphibians, especially salamanders and newts (caudates). Chronic toxicity was tested on eggs and larvae, and acute toxicity was tested on eggs, larvae, and adults. For eggs, chronic exposure to ZnO nanoparticles caused higher mortality at 10.0 and 100.0 mg/L compared to 0.0, 0.1, and 1.0 mg/L. When given an acute exposure (24h) to nanoparticles at a late incubation stage, …

Graphic Memoir As A Tool For Imaginative Leaping, Shay Larsen

Undergraduate Honors Capstone Projects

The idea for this capstone was sparked in the last semester of my third year of undergraduate research at Utah State University. I had been researching the ways in which creative nonfiction writers approached the realm of surreality in their work with my honors contract advisor, Dr. Jennifer Sinor. Sinor herself had written a piece ("Holes in the Sky") that dealt heavily in abstractions paralleled with the works of American artist Georgia O'Keeffe. While discussing the difficulties of expressing surreality in writing I made an offhand comment along the lines of "makes you wish you'd been a painter instead of …

The Influence Of Invasive Plants On The Small Mammal Community In A Cold Desert, Trinity N. Smith

Undergraduate Honors Capstone Projects

Exotic invasive species can alter ecosystem health. Cheatgrass (Bromus tectorum), Russian thistle (Salsola kali) and tall tumble mustard (Sisymbrium altissimum) are widely distributed invasive plants occurring throughout desert and shrub-steppe communities in the western United States. Due to the relative ease of capture, small mammal community metrics are often used to quantify overall ecosystem health. Studies examining small mammal communities are numerous but few have specifically examined the effects of invasive plants at the community level in arid ecosystems. In this study I examined community level small mammal responses to changes in microhabitat features, …

Meta-Analysis On Zoonotic Infectious Diseases Between Humans And Non-Human Primates, Madalyn R. Page

Undergraduate Honors Capstone Projects

Due to genetic similarity, non-human primates are often the focus of zoonotic infectious disease research. The objective of zoonotic disease research can vary depending upon whether the study is focusing on human health or the health of wild non-human primate populations. Research with non-human primates is often associated with their use in medical laboratories for the benefit of human health. However, other studies focus on both the health of wild non-human primate populations and human interactions. This study reviews zoonotic disease research published in three main primatology journals: American Journal of Primatology, International Journal of Primatology, and Primates. …

Embedding Language In Snack For Children With Disabilities, Alicen Irene Waldron

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

The number of children that are identified as having a language delay is increasing. According to Rescorla (p. 4 (1984)), “Language delay is the most common developmental problem found in preschool children.” Children with a language delay often struggle with reading and/or develop other types of learning disabilities (Aram & Nation, 1980). It is imperative that children with a language delay are identified early and that interventions are both effective and functional (Dunst, Raab, & Trivette, 2012). The preschool years are a critical period for language development. The impact of language delays can be lessened with interventions and support. Children …

Lady Macbeth And Early Modern Dreaming, Michela Schulthies

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

Lady Macbeth, the bloodthirsty queen of Scotland, wife of the butcher king Macbeth, is one of the most memorable female villains of English literature. Though William Shakespeare takes much of the content of Macbeth from Raphael Holinshed’s Chronicles of England, Scotland, and Ireland, Lady Macbeth is almost entirely his own creation. He takes a one-sentence character from his source and expands and elevates her to the infamous rank of Macbeth’s “dearest partner in greatness,” from which position she acts as the driving force behind his horrific deeds through much of the play (I.v.11). Perhaps the most famous of Shakespeare’s additions …

The Language Of Mathematics: Early Childhood Mathematics For Children Who Are Deaf Or Hard-Of-Hearing And The Role Of Parental Involvement, Alexandra Carlton

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

The development of the Common Core Standards sought to guide educators across the nation in providing commensurate academic programs and to define what students should know for career and college readiness. As of August 2013, forty-three states, the District of Columbia and four territories had adopted the Common Core Standards for grades kindergarten through twelve in the areas of English language arts and mathematics (National Association for the Education of Young Children [NAEYC], 2012; National Governors Association Center for Best Practices & Council of Chief State School Officers, 2010; Race to the Top Fund, 2014). To ensure kindergarten readiness, rigorous …

Landscapes Of Movement: Exploring A Contemporary Approah To Long-Distance Non-Motorized Backcountry Recreation Trail Planning, Christopher Monroe Binder

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

The discipline of long-distance non-motorized backcountry recreation trail planning and design has traditionally been defined by ad hoc, volunteer-based approaches. Despite the notable physical, affective, and cognitive benefits to individuals and populations derived from utilizing such trails, little progress has been made in framing a rigorous and contemporary method for their planning and design. Without such a framework, attempts in the field may fail to engage the advantages associated with the application of ordered process, cross-disciplinary proficiency, and geospatial technology that are continually evolving in the professional and academic landscape architecture, environmental planning, and natural resource management fields. This study …

Music: A Tool For Expressive And Receptive Vocabulary For Children Who Are Deaf Or Hard Of Hearing, Lauren Smith

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

Children with congenital hearing loss are at risk for speech, language, and academic delays. Early identification of hearing loss provides the opportunity for children who are deaf or hard of hearing (DHH) to obtain appropriate technology, such as hearing aids or cochlear implants, and to receive early intervention services to optimize development of listening and spoken language. Almost all industrialized countries have adopted policies for universal newborn hearing screening (National Center for Hearing Assessment and Management, 2011). This has significantly reduced the average age of identification from 2 ½ -3 years of age to 2-3 months of age (White, Forsman, …

Development Of Awwa Recommendations For Ccl4 Prioritization And Process, Ryan Worth Bench

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

Every 5 years the USEPA is responsible to publish a list of unregulated contaminants that are known or expected to occur in public water systems in the United States that may pose a risk on public health. This list is known as a contaminant candidate list (CCL). This year it is expected that the USEPA is to publish the 4th such list of the CCL or CCL4. Candidacy to be on the CCL4 is based on a compound’s occurrence in the environment, public health toxicity and recommendation from expert opinion. Methods to qualitatively determine occurrence and toxicity for compounds were …

Those Who See: Emily Dickinsons And May Swensons Poetic Language Of Spiritual And Scientific Possibility, Samantha Latham

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

Emily Dickinson and May Swenson are major American poets who use scientific language in order to explore the productive tension developed when core spiritual beliefs are challenged by new scientific observations and theories. Rather than shrink from the uncertainty resulting from the challenge to faith posed by Darwin in nineteenth-century America, Dickinson and Swenson blend scientific and spiritual language to move beyond the binary opposition often seen as separating these discourses. Dickinson responds most immediately to the advent of Darwinian thought, while Swenson builds on the work of Dickinson as she examines twentieth-century scientific discoveries ranging from the microscopic (the …

Managing The Spread Of Alfalfa Stem Nematodes Ditylenchus Dipsaci: The Relationship Between Crop Rotation And Pest Re-Emergence, Scott Jordan

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

Alfalfa is a critical cash/rotation crop in the western region of the United States, where it is common to find crops affected by the alfalfa stem nematode (Ditylenchus dipsaci). Understanding the spread dynamics associated with this pest would allow end-users to design better management programs and farming practices. This is of particular importance given that there are no nematicides available against alfalfa stem nematode and control strategies largely rely on crop rotation to non-host crops or by planting resistant varieties. I present a basic host-parasite model that describes the spread of the alfalfa stem nematode on alfalfa crops. With this …

The Effectiveness Of Livestock Exclosures In The Restoration Of Steelhead Onchorychus Mykiss Habitat And Populations In The John Day River Basin Of Eastern Oregon, Matthew Archibald

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

On March 25, 1999, the National Marine Fisheries Service (NMFS) listed the anadromous Oncorhynchus mykiss (O. mykiss), or steelhead, population in the Middle Columbia Evolutionarily Significant Unit (ESU) as threatened under the Endangered Species Act, and deemed that the federal Columbia River Hydropower System (FCRPS) posed jeopardy to this ESU. To mitigate for the impacts of the dams, the FCRPS Biological Opinion issued by NMFS, emphasized improving spawning and juvenile rearing habitat in the tributaries to achieve recovery of the population.

Navigating The Outdoor Recreation Folk Group: A Functional Analysis Of The Personal Narrative, Lori Lee

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

Among the participants of the outdoor recreation folk group, or people who participate regularly in human-powered outdoor recreation as a lifestyle, personal narratives are an integral and integrated part of interaction. This group is particularly rife with stories, because in the natural order of their lifestyle they regularly engage in activities filled with adventure and challenge. As members of this folk group engage in recreation together they share their personal narratives because it is the common tie between them, not only in interest, but in current participation and thus natural conversation. This common and simple tie sets the stage perfectly …

Climate, Latitude And Wealth, Trevor Greg Stringham

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

So many of the world's most impoverished nations are found in warm climate regions that some economists have referred to "tropical" as synonymous with "underdeveloped". In this paper I study the difference in GDP per capita throughout the world based on latitude, and show that there is a significant, positive correlation between distance from the equator and GDP per capita. I find that consumption is different in wealthier countries and that these differences are correlated with latitude. I use these differences in consumption as a new approach to evaluating the problem of what causes temperate climate nations to be rich …

Through Word Of Mouth Alone, Aiya Sakr

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

When I was five, my parents walked my older brother and me into what would become our bedroom. It had walls of bare cement, and they told us we could choose to paint it whatever color we wanted. My brother, the seven-year-old self-declared animal and nature expert, and I, his loyal follower, chose forest-green walls for trees, a gold-yellow ceiling for the sun, and dirt-brown carpeting for earth—mimicking the environment in Philadelphia, Pennsylvania, from which we had just moved to Amman, Jordan. That room, with its colored reminiscence of the world of my early childhood, would serve as the backdrop …

Methods For Growing Retinal Pigment Epithelial Cells: Current Protocols And Future Recommendations, Aaron H. Fronk

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

The retinal pigment epithelium (RPE) is a layer of tissue found in the vertebrate eye between Bruch’s membrane and the photoreceptor layer of the neural retina [1]. It is derived from the outer layer of the optic cup [2], possesses an innate immune system [3], and consists of a monolayer of highly pigmented cells that fit together in a tight matrix (fig. 1) [4]–[6]. The monolayer is often compared to a mosaic or cobblestones in its configuration, while the shape of the individual cells is usually described as polygonal/hexagonal, columnar (aligned perpendicular to the underlying membrane), or “epithelioid”. The cells …

Laboratory Study On The Effects Of Exit Face Inclination Of Critical Gradients, Richard Allen Keizer Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective of this research is to help better understand the effects of exit face inclinations on critical gradients. This will lead to more practical ways to predict critical hydraulic gradients and slope stability using soil properties and exit face conditions. Current geotechnical engineering does not consider these factors because they are not thoroughly understood. Despite the attempts to better predict critical gradients, methods developed over 70 years ago to model the heave mechanism are used to model failure mechanisms such as backward erosion (or piping). This critical hydraulic gradient is only calculated by means of the buoyant unit weight …

Greater Sage-Grouse Seasonal Habitat Models, Response To Juniper Reduction And Effects Of Capture Behavior On Vital Rates, In Northwest Utah, Avery Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The greater sage-grouse (Centrocercus urophasianus; sage-grouse) is a species of conservation concern in Utah and across their range throughout the western US and southern Canada. Sage-grouse decline is primarily a result of declines in sagebrush habitat on which sage-grouse depend for winter, summer, nesting, and brood habitat. Detailed site-specific knowledge of sage-grouse ecology and distribution in needed to effectively conserve the species. To expand knowledge of local populations within the West Box Elder Sage Grouse Management Area (SGMA) in NW Utah and gain insights into the effectiveness of vegetation treatments intended to benefit sage-grouse, I radio marked and …

Systems Optimization Models To Improve Water Management And Environmental Decision Making, Omar Alminagorta Cabezas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The degradation of water quality and wetlands is one of the most challenging environmental problems around the world. In spite of the magnitude of these environmental problems, few efforts identify how scarce resources (e.g., water, budget) can be more efficiently used to solve these problems. This dissertation presents a set of tools to help solve environmental problems related to excess phosphorus levels in water bodies and wetland degradation caused by water shortages and invasive vegetation. These tools are presented in three studies. The first study presents a simple optimization model that identifies the cost-effective combination of management practices to reduce …

Methods Of Processing Kenaf Chopped Strand Mats For Manufacturing Test Specimens And Composite Structures, Joshua W. Heil

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Every year in the United States, 10 to 11 million vehicles reach the end of their life cycle. Nearly all of these go to a recycling facility. After the recycling process is complete an average of 25% of each vehicle, by weight, goes to waste. This demonstrates the need to use natural fibers in parts that could be recycled, like parts that can be made from kenaf. There are many reasons to consider using natural/bio-fiber composites (bio-composites). These reasons include human health and environmental factors as well as advantages that natural fibers have over fiberglass, such as: lower costs and …
