Non-Suitable Habitat A Cause For Declining Bobolink Populations In Northern Utah, Bethany Q. Unger

Undergraduate Honors Capstone Projects

Bobolink, Dolichonyx oryxivories, populations are declining in Utah. I characterized the habitat conditions of known bobolink nesting sites in Utah and compared these conditions to those for nest sites in Wisconsin where bobolinks are abundant. My habitat assessment included identifying vegetation species, vegetation cover, pH, temperature, and precipitation at each site location. Vegetation cover different between Utah and Wisconsin nest sites. Precipitation varied for both locations with no correlation between water availability and bobolink presence. One possible driver for the reduction in bobolinks throughout Utah is the drastic increase in temperature. Other possible external factors include livestock grazing, edge distance, …

Women, Higher Education, And The Labor Market: A Cross-Cultural Understanding Of The Impact Of Religion, Allison Fife Hale

Undergraduate Honors Capstone Projects

How do deeply-held cultural perspectives shape the desire and ability of women to pursue higher education and or careers? More specifically, how do predominant religious and cultural perspectives on the family, the role of women, and the role of education influence a woman's decision to obtain higher education and her perceived ability or desire to seek full-time employment upon graduation? To answer these questions, this research utilized a cross-cultural survey instrument to compare and contrast the perceptions of female, undergraduate students in one predominantly Muslim/Middle Eastern society -- Dubai, U.A.E -- and one predominantly Mormon/Western society -- Utah, U.S.A. We …

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 …

The Poverty Of Prefectures: A Reevaluation Of The Memoir Of Zhang Daye, Joshua Defriez

Undergraduate Honors Capstone Projects

Everything today's readers know about the man Zhang Daye comes from his memoir, The World of a Tiny Insect (Wei Chong Shijie, 微蟲世界). The manuscript was distributed locally after its completion in 1894, though it never achieved wide-scale circulation. Wang Yongyuan of Zhejiang Normal University donated the only complete copy to the Chinese Academy of Sciences in the early 1950s where Harvard scholar Xiaofei Tian later discovered the manuscript. Since Tian's publication of an English translation in 2013, Zhang's writings have reached a wider audience than he likely ever imagined. As we read The World, Zhang's words …

Group Housing And Social Stress In Side-Blotched Lizards (Uta Stansburiana), Marilize Van Der Walt

Undergraduate Honors Capstone Projects

Stress in regards to an animal's social housing environment is well studied in mammals; however there are few studies examining this in reptiles and the results are thus far unclear. For example, behavioral evidence shows adverse effects from individual housing in juvenile chameleons, however physiological measures in whiptail lizards show adverse effects from group housing. Because some reptiles appear to be affected negatively by their social housing environment while others are impacted positively, if we can discover the reason for these differences, we will be able to implement the most effective housing regimes for reptiles. In this study, we tested …

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. …

Investigating The Pathogenecity Of Chl1 Leu17phe Polymorphism In Schizophrenia, Brooke Nichole Hansen

Undergraduate Honors Capstone Projects

Schizophrenia is a devastating brain disorder that affects a surprising 1% of the world's population. Despite this prevalence, little is known about the molecular aspects of this disorder making it both difficult to diagnose and treat. Several studies have identified the CHL1 gene (Close Homolog of L1), sometimes referred to as CALL, as a risk gene for schizophrenia. CHL1, a neural cell adhesion molecule, has major roles in cell migration, and the development of dendritic and axonal projections. Therefore any deficiency in CHL1 may result in brain defects similar to those identified in schizophrenic populations. Moreover, in genetically engineered mice, …

Increasing Vaccine Accessibility Through Cost Alternative Manufacturing And Elimination Of The Cold Chain, Jorgen Madsen

Undergraduate Honors Capstone Projects

Millions of people die each year from infectious diseases. This is partly due to the difficulty of transporting temperature dependent vaccines through what is called the cold chain in developing countries. I hypothesize that we can increase vaccine accessibility by finding cost effective alternatives to vaccine production and by eliminating the cold chain through vaccine stabilizers. The gold standard in purification of influenza virus is by means of ultracentrifugation. Although effective, this process is very expensive and thus impractical for developing countries. I hypothesize that column chromatography can be a cost efficient alternative that is as effective as ultracentrifugation. The …

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 …

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 …

An Overview Of Batrachochytrium Dendrobatidis In Utah, With A Focus On Boreal Toads And Their Changing Conservation Status, Samantha A. Beirne

Undergraduate Honors Capstone Projects

The Boreal Toad (Anaxyrus boreas) has disappeared from a large portion of its range in southern Utah and it has been questioned whether Batrachochytrium dendrobatidis (Bd, also known as chytrid) has played a role in its disappearance. The role of chytrid in range contraction of Boreal Toads and other amphibians in Utah is unknown. The primary objective of this project is to determine if any historic Boreal Toad specimens have chytrid to determine its arrival in Utah. If any old specimens test positive, the secondary goal of this study is to determine if there is a relationship between …

Unwanted Sexual Experiences: Exploring Conservative Socialization As An Important Contextual Factor, Analise Barker

Undergraduate Honors Capstone Projects

This mixed methods study examined sexual assault experiences and interpretations within a conservative religious context. In study one, male and female undergraduates (n=234) responded to survey questions assessing religious dogmatism, sexist ideology, traditional gender roles, and rape myth acceptance. Religious fundamentalism was related to rape myth acceptance for women, but not men, and both benevolent sexism (e.g., chivalry) and traditional gender role adherence fully mediated the relationship between religious fundamentalism and rape myth acceptance for women. In study two, 14 women were interviewed about their unwanted sexual assault experiences (USE) and were asked to evaluate their experiences with reference to …

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, …

This project was designed as a way for me to create lesson plans that incorporate the research proven highly effective method of using storytelling to teach math. My plan is to incorporate these lesson plans into my future classroom. All of the lesson plans are based on the math common core standards and as such are designed to help students understand and be able to apply these concepts in real-life situations. The main objective of using storytelling to teach these lessons is to help make math "come alive" for these students and help to show them that math can be …

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, …

Cultural Influences On Women In Leadership: An Extension Of The Hofstede And Globe Dimensions, Wendy Bosshardt

Undergraduate Honors Capstone Projects

Technology has forever changed the face of business. Although in the past business markets have been limited to local geographic areas, the concept of outsourcing has opened a diverse spectrum of international markets. An increase in suppliers and consumers can improve business effectiveness and efficiency, but entering international markets can be detrimental if the business is unaware of the subtle differences the new market has in regard to leadership styles and cultural values. Hofstede's cultural dimension analysis has been the primary research study for many industry and academic professionals (Bond 2002; Hofstede 1997). However, many scholars are questioning whether Hofstede's …

Developing A Portable System For Measuring Human Motor Learning, Karen Elizabeth Tew

Undergraduate Honors Capstone Projects

Point-to-point reaching is a commonly used paradigm in the field of human motor control. By studying how people move their arms from one location in space to another, researchers have gained insight into how the central nervous system controls and learns skilled movement. Many experimental methods that are designed to study reaching are not portable. This makes it difficult for researchers to access certain clinical populations with limited mobility or motor dysfunction. We have addressed this issue by developing a point-to-point reaching system that can capture key movement variables (e.g. speed and accuracy) yet is portable and inexpensive. We have …

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 …

Sources Of Uncertainty In Stream Nutrient Sampling Below A Point Source, Alexandria Hayden Campbell

Undergraduate Honors Capstone Projects

The goal of this study was to determine what aspects of sampling and sample storage could lead to uncertainty when taking samples in a stream below a point source. Sources of uncertainty studied were the locations where the samples were taken to assess if nutrients were adequately mixed within a cross-section, different filtration techniques, dilution errors, analytical uncertainty, and freezing time. Bootstrapping analyses were used to determine whether mixing and dilution errors led to uncertainty, while one-way ANOVAs were used to evaluate filtration techniques and storage time. Sample spikes to determine percent recovery of nutrients and repeat sample analyses are …

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 …

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. …

Empowering Community Partners: A Case Study Motivating Environmentally Sustainable Behavioral Changes In Latino Migrant Agricultural Families, Jessica Ivy Thomson

Undergraduate Honors Capstone Projects

Environmental sustainability outreach programs can benefit significantly through adaptation that connects to and fosters change within the Spanish speaking community. This article demonstrates a case study in which the authors partnered with a local Latino organization through an undergraduate service-learning project. The goal of this project was to incorporate environmentally sustainable behaviors both with young Latino students in school and with their families at the household level.

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 …

The Affordable Care Act: Five Years Later, Andrew Dana Izatt

Undergraduate Honors Capstone Projects

The challenges facing the American health care system are well known and manifold. The United States pays substantially more for its health care than any other developed, industrialized nation. Per capita health care spending in 2012 was $8,745, up from $356 in 1970 without marked improvements in life expectancy, quality of life, or outcomes. But despite all of our health spending, large portions of our population go without health insurance. Being uninsured carries real consequences. A report published in the American Journal of Public Health, by researchers at Harvard Medical School, using statistics from the Centers for Disease Control and …

Quality Of State Attorneys' Oral Arguments In Supreme Court Litigation, Kaylee Johnson

Undergraduate Honors Capstone Projects

In my thesis, I evaluate the conventional wisdom that attorneys representing state governments performed poorly in oral arguments before the Supreme Court. This led the National Association of Attorneys General in 1982 to create the Supreme Court Clearinghouse Project. The project was implemented in an effort to improve the quality of states' efforts before the Court. Pulling from Justice Blackmun's ratings of attorneys in oral arguments, I conduct a quantitative analysis to determine whether such efforts actually led to an improvement in states' performance in Supreme Court litigation. I take the 1,142 cases in which states were involved from 1970-1993 …

Improving Micro-Finance Productivity Through Data Analysis, Ryan D. Taylor

Undergraduate Honors Capstone Projects

After nearly three months of gathering, creating, organizing, and analyzing data from social entrepreneurship programs in Peru and Ghana, correlations have been found within the data which may be used in the pursuit to eliminate poverty around the globe. These correlations were found through completing both linear relationship analyses and multi-variable regression analyses. The most statistically significant factors when looking at correlational relationships with number of missed and late payments were APR, loan duration, loan date (year fraction), gender or principle loan participant, and participation in incentive programs. The most poignant of these variables in terms of statistical significance was …

Ethnic Minority High School Students: Academic Self-Efficacy And College Preparedness, Melanie Ann Faustino Hansen

Undergraduate Honors Capstone Projects

In an effort to better understand high school student's academic self-efficacy and college preparedness, 165 students were surveyed at the Utah State University event Diversity Day held on November 21st, 2014. As such, we collaborated with the Utah State University Admissions office so that all evaluation materials and results could be used for future recruitment purposes. Students were asked questions designated to gain insight into the factors they determined to be important when choosing to attend college, selecting a college to attend, and how prepared they viewed themselves to succeed in college. In addition, basic measures were also taken that …

Wickiup Site Structure: A Comparison Of Aboriginal Wooden Features From The Great Basin And Colorado Plateau, Brandi Jensen Allred

Undergraduate Honors Capstone Projects

Throughout all of human history, people have built shelters for themselves whenever they stop for more than a few minutes. Many of these structures, built from wood and brush, are today colloquially known as wickiups. Wickiups are temporary housing structures, but were sometimes used for longer duration or even winter stays. In the Great Basin and surrounding montane West, we have a surprising amount of still standing wickiups. These have yet to fall to time's ravages and were initially built within the last several hundred years. Older sites, those around the world and deep into time, no longer have the …
