The Emperor's New Clothes: How The New Atheists Are Reminding The Humanities Of Their Place And Purpose In Society., David Ira Buckner
The Emperor's New Clothes: How The New Atheists Are Reminding The Humanities Of Their Place And Purpose In Society., David Ira Buckner
Electronic Theses and Dissertations
This dissertation will examine the social and intellectual impact of the so-called “New Atheism” as evidenced by the writings and public careers of its four principal protagonists: evolutionary biologist Richard Dawkins, philosopher Daniel Dennett, journalist Christopher Hitchens, and neuroscientist Sam Harris. I will argue that the New Atheists together provide an account of reality philosophically superior to that of theism, including those superficially sophisticated variations espoused in the writings of scholars William Lane Craig, John Lennox, Allister McGrath, Alvin Plantinga, etc. Yet, even if this were not so, I would still contend that the accessible, informative, and provocative style of …
The Role Of Aldehyde Dehygrogenase 2 In Liver Injury Caused By Vinyl Chloride And High-Fat Diet., Liya Chen
The Role Of Aldehyde Dehygrogenase 2 In Liver Injury Caused By Vinyl Chloride And High-Fat Diet., Liya Chen
Electronic Theses and Dissertations
Background. Vinyl chloride (VC) is an abundant environmental contaminant that causes steatohepatitis at high exposure levels. We have shown previously that low concentrations of VC exacerbate high fat diet (HFD)-induced liver injury in mice. The mechanisms involved in the progression of liver injury caused by VC and HFD include oxidative stress, inflammation, metabolic and mitochondrial dysfunction. Mitochondrial aldehyde dehydrogenase 2 (ALDH2) serves as a key line of defense against most reactive aldehydes, including lipid aldehydes (e.g., 4-HNE) and chloroacetaldehyde (VC metabolite). We hypothesize that this defense may play a key role in the interaction between HFD and VC in fatty …

Is The Sum Greater Than The Parts? A Qualitative Case Study Of Cross-Functional Team Creativity., Tracy J. Richardson
Electronic Theses and Dissertations
Creativity is an important capability for organizations to develop solutions for complex challenges. Cross-functional teams are often used within organizations in the hope of leveraging diverse perspectives to develop creative ideas. However, the process by which cross-functional teams generate new ideas is often elusive in practice and poorly understood in research. A case-study design was used to explore the complex nature of the creative process within a services industry organization, which is an understudied context for creativity. The study focused on the knowledge sharing and knowledge integration processes for cross-functional teams as well as overall team effectiveness. The results of …

The Regional Distribution And Molecular Interactions Of Phospholipids And Glucose In Mammalian Vitreous Humors., Abigail Nicole Schnepf
The Regional Distribution And Molecular Interactions Of Phospholipids And Glucose In Mammalian Vitreous Humors., Abigail Nicole Schnepf
Electronic Theses and Dissertations
The vitreous humor (VH) is located in between the lens and the retina. It is composed of 98% water, hyaluronan (HA), collagen, proteins, phospholipids (PLs), and other metabolites. With aging, the VH undergoes liquefaction, a process that causes the gel-like structure of the VH to turn into a liquid and can lead to serious ocular diseases, including retinal detachment, vitreal detachment, and macular hole formation. The liquefaction process is expedited in diabetic VHs. This project focuses on understanding the molecular changes that lead to liquefaction and the reasons for which this process is accelerated with diabetes. Matrix-assisted laser desorption ionization/mass …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Some children with autism spectrum disorder (ASD) struggle to perform a series of academic tasks, like academic worksheets, independently. Photographic activity schedules are one technique that has been demonstrated to promote independent behavior in individuals with ASD. This study examined how activity schedules impacted the accurate and independent completion of a series of academic worksheets for three young children with ASD ages 6 and 7. Participants needed to performed a series of math and reading worksheets in the presence of an adult, but struggle to display those concepts accurately in the absence of an adult. Procedures involved training participants to …

Patterns Of Use Before And After A Labeling Intervention Among Collegiate Division I Athletes At A Fueling Station, Julie A. Buzzard
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Fueling Station at Utah State University was created to provide pre-workout fueling and post-workout recovery foods to the Utah State University athletes. The athletes use an online survey to mark what foods they selected after each visit to the Fueling Station.
There is a large amount of research on the lack of sports nutrition knowledge in collegiate athletes, but there is little information on the dietary intake of athletes, the education of athletes, and the education of macronutrient timing in athletes.
A food labeling system named “Gain Your Edge” food labels that targeted the education of timing was created …
Sociodemographic And Climatic Factors Shaping The Development Of Drought Policies In Major U.S. Cities, Riana S. Gayle
Sociodemographic And Climatic Factors Shaping The Development Of Drought Policies In Major U.S. Cities, Riana S. Gayle
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In most parts of the world, drought is an inevitable and natural occurrence. However, as the climate continues to warm, and populations grow and expand, the negative impacts of this extreme weather event are predicted to become more pronounced. This leads many communities and stakeholders to question what is being done to prepare society for widespread drought? The following research determines different social and atmospheric characteristics that affect a city’s likelihood of having a drought policy in place.To do this, a thorough search was conducted at the city level to determine where drought policies are currently located in theU.S. The …
New Ca-Id-Tims Detrital Zircon Constraints On Middle Neoproterozoic Sedimentary Successions, Southwestern United States, Abigail R. Bullard
New Ca-Id-Tims Detrital Zircon Constraints On Middle Neoproterozoic Sedimentary Successions, Southwestern United States, Abigail R. Bullard
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Three related sedimentary successions located in Arizona, Utah, and California were deposited in basins on proto-North America during the early rifting of Rodinia (~780 Mya). Previous detrital zircon U-Pb maximum ages for the units are inexact, making it difficult to piece together what happened at this point in Earth history.
We report better maximum age constraints on these units obtained by subjecting detrital zircons to high-precision CA-ID-TIMS analysis, which provide more exact 206Pb/238U ages. These new data significantly improve the precision for the base of the ChUMP units, with an average age of 775.63 ± 0.27 Ma …
Improving Accuracy Of The Edgebox Approach, Kamna Yadav
Improving Accuracy Of The Edgebox Approach, Kamna Yadav
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Object region detection plays a vital role in many domains ranging from self-driving cars to lane detection, which heavily involves the task of object detection. Improving the performance of object region detection approaches is of great importance and therefore is an active ongoing research in Computer Vision. Traditional sliding window paradigm has been widely used to identify hundreds of thousands of windows (covering different scales, angles, and aspect ratios for objects) before the classification step. However, it is not only computationally expensive but also produces relatively low accuracy in terms of the classifier output by providing many negative samples. Object …
Historical Channel Change Caused By A Century Of Flow Alteration On Sixth Water Creek And Diamond Fork River, Ut, Jabari C. Jones
Historical Channel Change Caused By A Century Of Flow Alteration On Sixth Water Creek And Diamond Fork River, Ut, Jabari C. Jones
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Changes in the amount of water and sediment that enter a river can change its shape and size. The way that rivers change is affected by a variety of factors, including the size of the sediment in the river, and past changes to the river. The Diamond Fork River in central Utah has been altered by water delivered from the Colorado River system for over a century. Beginning in 1915, water used for irrigation was delivered through a tributary, Sixth Water Creek, with daily summer flows that were much larger than natural flows. This caused drastic change to the rivers, …
Organic Matter Sources, Composition, And Quality In Rivers And Experimental Streams, Julia E. Kelso
Organic Matter Sources, Composition, And Quality In Rivers And Experimental Streams, Julia E. Kelso
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Organic matter (OM) is often considered the “currency” for ecosystem processes, such as respiration and primary production. OM in aquatic ecosystems is derived from multiple sources, and is a complex mixture of thousands of different chemical constituents. Therefore, it is difficult to identify all the sources of OM that enter and exit aquatic ecosystems. As humans develop undisturbed land, the rate at which terrestrial OM (e.g. soil and plants) and associated nutrients (e.g. nitrogen) enters rivers has increased. Increased nutrients may lead to increased primary production from aquatic plants and algae, potentially causing eutrophication and harmful algal blooms. …
Supporting Adolescent Metacognition In Engineering Design Through Scripted Prompts From Peer Tutors: A Comparative Case Study, Kristin Marie Strong
Supporting Adolescent Metacognition In Engineering Design Through Scripted Prompts From Peer Tutors: A Comparative Case Study, Kristin Marie Strong
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In 2013, developers of the Next Generation Science Standards implemented national K-12 directives and elevated engineering design to the level of scientific inquiry. Teaching design, however, is challenging to educators due to the complex nature of design problems, which cannot be solved via simple algorithms. Solving design problems requires a more reflective and iterative approach that emphasizes metacognitive skills like planning, monitoring, and taking another person’s perspective. Educators are further challenged by children’s immature metacognitive skills, which may be insufficient to engage in the entire design process.
A qualitative study of paired seventh graders demonstrated a pragmatic learning activity for …

Comparing Performance Of Gene Set Test Methods Using Biologically Relevant Simulated Data, Richard M. Lambert
Comparing Performance Of Gene Set Test Methods Using Biologically Relevant Simulated Data, Richard M. Lambert
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Today we know that there are many genetically driven diseases and health conditions. These problems often manifest only when a set of genes are either active or inactive. Recent technology allows us to measure the activity level of genes in cells, which we call gene expression. It is of great interest to society to be able to statistically compare the gene expression of a large number of genes between two or more groups. For example, we may want to compare the gene expression of a group of cancer patients with a group of non-cancer patients to better understand the genetic …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Chocó-Darien Global Ecoregion (CGE) in South America is one of 25 global biodiversity hotspots prioritized for conservation. I performed the first land-use and land-cover (LULC) change analysis for the entire CGE in this dissertation. There were three main objectives: 1) Select the best available imagery to build annual land-use and land-cover maps from 2001 to 2015 across the CGE. 2) Model LULC across the CGE to assess forest change trends from 2002 to 2015 and identify the effect of proximate causes of deforestation and reforestation. 3) Estimate the effects of underlying drivers on deforestation and reforestation across the CGE …
Development Of An Improved Low-Order Model For Propeller-Wing Interactions, Joshua Taylor Goates
Development Of An Improved Low-Order Model For Propeller-Wing Interactions, Joshua Taylor Goates
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
For aircraft that have propellers mounted in front of the wings or tail, the prop wash produced by the propellers can have a strong influence on the aerodynamics of the aircraft. As the accelerated air from the propeller flows over the wings and tail, it can cause an alteration in the aerodynamic forces produced by those surfaces. Thus, an understanding of propeller-wing interactions is essential for the design and analysis of many aircraft.
There are multiple existing methods for analyzing the propeller-wing interactions. High order methods, such as wind tunnel testing or computational fluid dynamics, provide very accurate results but …
Renewable Portfolio Standards And Environmental Goals, Josh T. Smith
Renewable Portfolio Standards And Environmental Goals, Josh T. Smith
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Renewable portfolio standards (RPS) are one of the most common state policies meant to encourage clean energy use. They require that utilities purchase electricity from certain qualifying electricity generators, usually with no reference to the cost of that electricity. AlthoughRPS are meant to clean up electricity generation through using clean energy sources instead of fossil fuels, they may not do so effectively. Further, some energy companies may lobby state legislators to include their energy sources regardless of their actual environmental benefit. The actual relationship between enacting an RPS and a state’s emissions from energy production is unclear. I explore RPS …
Study Of The 3Ω Measurement Of The In-Plane And The Cross-Plane Thermal Properties On Anisotropic Thin Film Materials, Daxi Zhang
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Due to the size of the nano-scale and micro-scale materials, traditional method for measuring the thermal properties of the bulk materials cannot be applied. The 3 Omega Method was developed by D. G. Cahill in the early 90s. It was used extensively to measure the thermal properties of thin film dielectric materials. Compare with other simulations or experimental methods, the 3 Omega Method has many advantages. Previous research has indicate that the 3 Omega method is capable of measuring the cross-plane thermal conductivity of thin film materials. In extension, an alternative improvement for measurement of the in-plane thermal conductivity and …
Identification Of Sperm Chromatin Proteins As Candidate Markers Of Stallion Fertility, Chelsea C. Ketchum
Identification Of Sperm Chromatin Proteins As Candidate Markers Of Stallion Fertility, Chelsea C. Ketchum
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
During spermatogenesis, histones are largely replaced by transition proteins and protamines in normal stallions. Incomplete nucleoprotein exchange results in the abnormal retention of histones and transition proteins, which is an indicator of poor sperm quality. Equine nucleoprotein exchange has not previously been investigated in detail, so that equine sperm chromatin quality problems, which are often responsible for poor breeding performance of stallions, are not well understood. In order to characterize chromatin remodeling events in stallion spermatogenesis and to identify proteins indicative of sperm chromatin defects, such as excessive amounts of histones, we identified antibodies that recognize equine testis-specific proteins of …

The Nesting Ecology Of Woodpeckers In The Eastern Cascades And Their Interactions With Nest Competitors And Predators, Samuel D. Cowell
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Woodpeckers create nesting cavities for other birds and animals in forests. This creates dynamic interactions between both woodpeckers and these other animals. Using video cameras, we documented direct behavioral interactions between nesting woodpeckers and other animals in the Eastern Washington Cascades during the 2015 and 2016 breeding seasons. Additionally, we offered 937 students in a General Biology laboratory course to participate in this original research opportunity and described and the impact the experience had on the participants as well as the researchers.
In 2015, Western Blubebirds took over two active Black-backed Woodpecker nests by physically attacking the woodpeckers. In 2016, …

This study examines the price differences of commonly consumed produce between farmers’ markets and grocery stores in Utah. Our first objective is to compare price differences of a basket of produce between farmers’ markets and grocery stores. We compare these price differences in terms of low-income consumer affordability and if an individual can afford a market basket of produce using a combination of Farmers’ Market Nutrition Program (FMNP) dollars and Double Up Food Bucks (DUFB) incentive dollars. Our second objective for this study is to establish the price premiums of individual produce items based on where the produce was sold, …
The Power Law Distribution Of Agricultural Land Size, Lauren Chamberlain
The Power Law Distribution Of Agricultural Land Size, Lauren Chamberlain
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This paper demonstrates that the distribution of county level agricultural land size in the United States is best described by a power-law distribution, a distribution that displays extremely heavy tails. This indicates that the majority of farmland exists in the upper tail. Our analysis indicates that the top 5% of agricultural counties account for about 25% of agricultural land between 1997-2012. The power-law distribution of farm size has important implications for the design of more efficient regional and national agricultural policies as counties close to the mean account for little of the cumulative distribution of total agricultural land. This has …

Spatial Ability Degradation In Undergraduate Mechanical Engineering Students During The Winter Semester Break, Benjamin J. Call
Spatial Ability Degradation In Undergraduate Mechanical Engineering Students During The Winter Semester Break, Benjamin J. Call
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Spatial ability represents our ability to mentally arrange, rotate, and explore objects in multiple dimensions. This ability has been found to be important for engineers and engineering students. Past research has shown that many interventions can be created to boost an individual’s spatial ability. In fact, past research has indicated that engineering students significantly increase in spatial ability without an intervention while they are enrolled in certain engineering courses. Some researchers have claimed that the spatial ability boosts are permanent after an intervention. However, most researchers do not check the validity of that claim with continued assessment after more than …
Predicting U.S. Adolescents’ Purchasing Of Denim Jeans Using Quality Attributes, Behavioral Characteristics, And Sociodemographics, Michelle Clouse

The purpose of this study was to establish a predictive model of the factors that contribute to the decision-making process when purchasing denim by 13- to 19-year-old adolescents living in the U.S. The researcher created an online survey through Qualtrics and administered it to an opt-in panel of adolescents, through Centiment. There were 460 survey responses collected.
Important denim attributes to respondents included comfort and fit, price, durability, and body perception. Significant predictors that increased respondents’ intention to purchase denim jeans included intrinsic attributes-appearance of fabric on the body, cognitive attributes, tighter fit, and purchased denim in the last three …
The Influence Of Mechanical Stratigraphy On Thrust-Ramp Nucleation And Propagation Of Thrust Faults, Sarah S. Wigginton
The Influence Of Mechanical Stratigraphy On Thrust-Ramp Nucleation And Propagation Of Thrust Faults, Sarah S. Wigginton
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Our current understanding of thrust fault kinematics predicts that thrust faults nucleate on low angle, weak surfaces before they propagate upward and forms a higher angle ramp. While this classic kinematic and geometric model serves well in some settings, it does not fully consider the observations of footwall deformation beneath some thrust faults. We examine an alternative end-member model of thrust fault formation called “ramp-first” fault formation. This model hypothesizes that in mechanically layered rocks, thrust ramps nucleate in the structurally strong units, and that faults can propagate both upward and downward into weaker units forming folds at both fault …
