The Power-Duration Relationship Is Just As Reproducible In Females As Males, Despite The Presence Of The Menstrual Cycle, Jessica Joy Linde May 2022

The Power-Duration Relationship Is Just As Reproducible In Females As Males, Despite The Presence Of The Menstrual Cycle, Jessica Joy Linde

Theses and Dissertations

PURPOSE: To investigate the effect of the menstrual cycle (MC) on exercise performance across the power-duration relationship (PDR). We hypothesized females would exhibit greater variability in the PDR across the MC than males across a similar timespan, with critical power (PCRIT) and Work prime (W') being lower during the early follicular phase than the late follicular and mid-luteal phases. METHODS: Eumenorrheic, endurance-trained females (n = 10, age = 24.1 ± 5.59) performed multiple constant-load-to-task-failure and maximum-power tests at three time points across the MC (early follicular, late follicular, midluteal phases). Endurance-trained males (n = 10 age = 29.5 ± 9.18) …

Between The Garden And The Gardener, Sara Lynne Lindsay May 2022

Between The Garden And The Gardener, Sara Lynne Lindsay

Theses and Dissertations

My work uses plant material and soil as a record of personal, cultural, and ecological history. History is not only held in the buildings and monuments, but in the soil itself. I gather this soil and foliage from both cultivated and uncultivated locations for my artwork. Using traditional domestic techniques of drying and canning, I preserve the materials that I have gathered. These will then be sewn together, cooked, and encrusted into objects. Despite my labor of preserving, these organic art supplies are transient. When made into works of art, they can be viewed in their vulnerable state, fighting against …

The Christian Approach To Psychology, Preston Keller May 2022

The Christian Approach To Psychology, Preston Keller

Student Works

This article analyzes the implications of the current worldview of contemporary psychology and demonstrates that these implications are not compatible with the worldview of a Christian approach to psychology. The contrast between Greek Naturalism and Hebrew Theism are presented as the historical foundations for the worldviews of contemporary psychology and Christianity, respectively. The ontological, epistemological, and ethical assumptions of a Christian approach to psychology are explored. The Christian approach to human flourishing, psychopathology, and psychotherapy are contrasted against contemporary psychology's approach to these three areas. The article concludes by suggesting that the field of contemporary psychology should make space for …

Mite Infestation Of Two Species Of Xenosaurus (Squamata: Xenosauridae) From Contrasting Environments, Jonhatan Olvera-Arrieta, Geoffrey R. Smith, Guillermo A. Woolrich-Piña, Julio A. Lemos-Espinal, Héctor Gadsen May 2022

Mite Infestation Of Two Species Of Xenosaurus (Squamata: Xenosauridae) From Contrasting Environments, Jonhatan Olvera-Arrieta, Geoffrey R. Smith, Guillermo A. Woolrich-Piña, Julio A. Lemos-Espinal, Héctor Gadsen

Western North American Naturalist

Mite prevalence and load can vary among populations and species of lizards. We report on chigger mite (Eutrombicula alfreddugesi) prevalence and load in a temperate population of Xenosaurus fractus and a subtropical population of Xenosaurus rectocollaris. Mites were more prevalent and found in greater numbers (i.e., higher load) on X. rectocollaris than on X. fractus. Mite load in both species did not differ between July/August and October/November. Differences in mite load and prevalence among populations and species of Xenosaurus from different types of environment suggest that more study is needed to understand how environmental factors affect …

Number Manipulation For Profit, Or Just For Fun?, Paul Y. Hoskisson May 2022

Number Manipulation For Profit, Or Just For Fun?, Paul Y. Hoskisson

Insights: The Newsletter of the Neal A. Maxwell Institute for Religious Scholarship

When the writer of the Gospel of Matthew listed the genealogy of Christ, he divided it into three sections, each containing 14 generations, to wit, Abraham to David, David to the Exile, and the Exile to Christ (Matthew 1:17; also 1–17). In order to do this he had to manipulate the names by leaving out several ancestors mentioned in the Old Testament. The reason Matthew thought it necessary to create this mathematical/genealogical fiction has never been explained adequately.

Tabletop Extreme-Ultraviolet Source Using High Harmonic Generation For Polarization Sensitive Imaging, Taylor Jordan Buckway May 2022

Tabletop Extreme-Ultraviolet Source Using High Harmonic Generation For Polarization Sensitive Imaging, Taylor Jordan Buckway

Theses and Dissertations

We are developing a tabletop extreme-ultraviolet source using high harmonic generation at Brigham Young University. The thesis goes over the theory of high harmonic generation using the three-step model. This tabletop source was designed for probing magnetic domains of iron nanoparticles. We present optimization of the 42 eV and 52 eV harmonics through phase matching. Phase matching consists of tuning the intensity of the IR beam and pressure of the gas medium. The target gas medium used for this thesis is argon. The 42 eV harmonic was optimized to 8.2 billion photons per second. This was used with a 1500 …

Who's Hiding On The Savanna?, Amanda Morgan

Children's Book and Media Review

From sunset to sunrise, the savannah is full of interesting animals. In the morning, female lions can be found in the shade with two or three cubs. In the afternoon, hippos hold their breath for up to five minutes underwater. In the evening, vervet monkeys eat leaves and flowers as they lurk in branches. At night, superb starlings gather in large groups to sleep in trees.

Animal Atlas, Amanda Morgan

Children's Book and Media Review

There are animals from every continent and ocean. In North America, monarch butterflies migrate from Canada and the US to Mexico. The bee hummingbird lives in what little remains of the Cuba tropical forest. In Asia, the Baikal seal can be found in Lake Baikal, where two-thirds of the plants and animals are unique to the lake. In Australia, kiwis roam among the kauri trees, and saltwater crocodiles live in the brackish rivers leading to the Indian Ocean. Deep in the Mid-Atlantic Ridge, find mysterious animals like Murray’s abyssal anglerfish, and in the seagrass meadows of the Indian Ocean, leafy …

Network Specialization: A Topological Mechanism For The Emergence Of Cluster Synchronization, Ethan Walker May 2022

Network Specialization: A Topological Mechanism For The Emergence Of Cluster Synchronization, Ethan Walker

Theses and Dissertations

Real-world networks are dynamic in that both the state of the network components and the structure of the network (topology) change over time. Most studies regarding network evolution consider either one or the other of these types of network processes. Here we consider the interplay of the two, specifically, we consider how changes in network structure effect the dynamics of the network components. To model the growth of a network we use the specialization model known to produce many of the well-known features observed in real-world networks. We show that specialization results in a nontrivial equitable partition of the network …

Disproportionate Exposure To Air Pollution For Low-Income Communities In The United States, Elisabeth Currit May 2022

Disproportionate Exposure To Air Pollution For Low-Income Communities In The United States, Elisabeth Currit

Ballard Brief

While air pollution is a major problem in much of the United States, individuals of low socioeconomic status are disproportionately exposed to air pollution compared to wealthier individuals.1 Contributing factors to the problem of disproportionate exposure to air pollution for low-income communities in the United States include lack of emissions regulations and enforcement, disproportionate placement of pollution sources nearby low-income neighborhoods, and the excessive political power of large emitters. The negative consequences that low-income individuals suffer because of this include both physical and mental health as well as impaired cognitive function. NGOs and other organizations are creating programs to help …

Age-Related Differences In Food-Specific Inhibitory Control: Electrophysiological And Behavioral Evidence In Healthy Aging, Whitney D. Allen Apr 2022

Age-Related Differences In Food-Specific Inhibitory Control: Electrophysiological And Behavioral Evidence In Healthy Aging, Whitney D. Allen

Theses and Dissertations

The number of older adults is estimated to double from 52 million to 95 million by 2060. Approximately 80-85% of older adults are diagnosed with a chronic health condition. Many of these chronic health conditions are influenced by diet and exercise, suggesting improved diet and eating behaviors could improve health-related outcomes. One factor that might improve dietary habits in older adults is food-related inhibitory control. We tested whether food-related inhibitory control, using behavioral (response time, error rate) and scalp-recorded event-related potential (ERP; N2 and P3 components) measures of food-related inhibitory control differed between younger and older adults over age 55. …

Acoustofluidics For Simultaneous Nanoparticle-Based Drug Loading And Exosome Encapsulation, Zeyu Wang, Joseph Rich, Nanjing Hao, Yuyang Gu, Chuyi Chen, Shujie Yang, Peiran Zhang, Tony Jun Huang Apr 2022

Acoustofluidics For Simultaneous Nanoparticle-Based Drug Loading And Exosome Encapsulation, Zeyu Wang, Joseph Rich, Nanjing Hao, Yuyang Gu, Chuyi Chen, Shujie Yang, Peiran Zhang, Tony Jun Huang

Faculty Publications

Nanocarrier and exosome encapsulation has been found to significantly increase the efficacy of targeted drug delivery while also minimizing unwanted side effects. However, the development of exosome-encapsulated drug nanocarriers is limited by low drug loading efficiencies and/or complex, time-consuming drug loading processes. Herein, we have developed an acoustofluidic device that simultaneously performs both drug loading and exosome encapsulation. By synergistically leveraging the acoustic radiation force, acoustic microstreaming, and shear stresses in a rotating droplet, the concentration, and fusion of exosomes, drugs, and porous silica nanoparticles is achieved. The final product consists of drug-loaded silica nanocarriers that are encased within an …

Snakebite!: Antivenom And A Global Health Crisis, Jennifer Haltli Apr 2022

Snakebite!: Antivenom And A Global Health Crisis, Jennifer Haltli

Children's Book and Media Review

One million people suffer from snake bites annually. Over 100,000 of them die, mostly in the eastern hemisphere. With 680 species of venomous snakes residing on all habitable continents, the antivenom crisis is global. The major economic barrier to antivenom is that the countries with the most desperate need are the very same countries that cannot afford it. Consequently, bite victims have learned not to rely on expensive antivenoms that would be effectively administered in hospitals, defaulting instead to ineffective folk remedies. Production of antivenom is expensive, but that's not the only problem. The world’s countries have different medical approval …

Tidal Translations: Thinking-With Untranslatability In Craig Santos Perez's From Unincorporated Territory, Maryn Gardner Apr 2022

Tidal Translations: Thinking-With Untranslatability In Craig Santos Perez's From Unincorporated Territory, Maryn Gardner

Theses and Dissertations

Craig Santos Perez's poetic series from Unincorporated Territory describes and decries the U.S. militarization, colonization, and environmental degradation of Guam in the Western Pacific through multilingual, excerpted, and series-long poems. Perez's writing style requires slow, careful reading with translations sometimes appearing on the same page, various pages later, or not at all. I describe this kind of elongated translation as slow translation, recalling translation theorist Michael Cronin's "Slow Language" movement. This thesis invites readers, especially multispecies ethnographers, to slow down the translation of nonhuman species and their stories by paying attention to moments of untranslatability in multispecies literature and interactions. …

Assessing Augmented Reality Instruction In Manufacturing Engineering Education, Janine Draper Price Apr 2022

Assessing Augmented Reality Instruction In Manufacturing Engineering Education, Janine Draper Price

Theses and Dissertations

Augmented Reality (AR) is fast-growing technology that has proved itself in many applications, including manufacturing environments. Manufacturing engineers benefit in an industrial environment by harnessing this technology in the workplace to guide workers through a variety of tasks. It is no longer a question on whether it is useful, but what are the best ways of applying the technology. Currently there are no published studies on ways to use augmented reality in a Manufacturing Engineering Educational Environment (MEEE). This study examines various ways that AR can be used in an MEEE setting and assesses the value of such applications. This …

Mindfulness And Observational Drawing, Corinne Christopherson Sonderegger Apr 2022

Mindfulness And Observational Drawing, Corinne Christopherson Sonderegger

Theses and Dissertations

Observational drawing has many benefits, yet it can be a difficult and frustrating curriculum for students and teachers alike. As I was teaching elementary and college art classes simultaneously, I noticed a significant discrepancy between my younger and older students. Students in my elementary art classes loved to draw and often expressed how excited they were to make art. However, students in my college art classes were more hesitant and self-conscious about drawing and did not believe they could progress artistically. Many of these students had abandoned drawing in elementary or middle school. This pattern evokes the U curve of …

Orienting Pacha: Value As Action In The Late Horizon Xauxa-Pachacamac Axis, Ridge C. Anderson Apr 2022

Orienting Pacha: Value As Action In The Late Horizon Xauxa-Pachacamac Axis, Ridge C. Anderson

Theses and Dissertations

The Andean Late Horizon (ca. AD 1438–1532) was a period of exceptionally rapid and far-reaching cultural change. Over this short span of only a few generations, the Inka ethnic group established an empire that was greater in size than any other pre-colonial American polity. The Inka accomplished their expansion without the use of certain institutions (i.e., a standing army, formal writing system, monetary system, or price-setting markets) that the received anthropological wisdom has long held as being necessary preconditions to imperial expansion. Standard explanations of Late Horizon culture change tend to overemphasize the roles of environmental constraints, social evolution, and …

Accurate Band Energies Of Metals With Quadratic Integration, Jeremy John Jorgensen Apr 2022

Accurate Band Energies Of Metals With Quadratic Integration, Jeremy John Jorgensen

Theses and Dissertations

Materials play an important role in society. Historically, and even at present, materials have been discovered by trial and error, and many of the most useful materials have been discovered by chance. The high-throughput approach aims to remove (as much as possible) chance and guesswork at the experimental level by filtering out materials candidates that are not predicted to exist. Many successes have been recorded. In the high-throughput approach to materials discovery, machined-learned models of materials are created from databases of theoretical materials. These databases are the result of millions of density-functional-theory (DFT) simulations. The size and accuracy of the …

Parental Incarceration As A Predictor Of Legal Cynicism, Mackenzie Joy Heim Apr 2022

Parental Incarceration As A Predictor Of Legal Cynicism, Mackenzie Joy Heim

Theses and Dissertations

Researchers have established that legal cynicism is linked to violence, deviant behavior, and crime. In response to the potentially dangerous implications of a legally cynical society, research in recent years has attempted to identify experiences and conditions that play a role in the development of legal attitudes. Given that youths' familial and social conditions appear to be influential predictors, this study tests the relationship between parental incarceration and legal cynicism. Data from the Fragile Families and Child Wellbeing Study were used for this analysis. Results from three OLS regression models indicate that parental incarceration is not a significant predictor of …

The Role Of Bacterial Genotype In The Persistence Of The Microbiota Of Drosophila Melanogaster, Sarah J. Gottfredson Apr 2022

The Role Of Bacterial Genotype In The Persistence Of The Microbiota Of Drosophila Melanogaster, Sarah J. Gottfredson

Theses and Dissertations

In this work we use the fruit fly Drosophila melanogaster as a model to identify bacterial genes that help bacteria to persist in their animal hosts. Early work on this model system established that dietary replenishment drives the composition of the D. melanogaster gut microbiota, and subsequent research has shown that some bacterial strains can colonize the fly for much longer than the flow of bulk diet through the gut. In this work we reveal that bacterial genes influence bacterial persistence by studying the correlation between bacterial genotype and persistence in the D. melanogaster gut microbiota. We performed an initial …

Biophysical Factors Control Invasive Grass Hot Spots In The Mojave Desert, Tanner Corless Smith Apr 2022

Biophysical Factors Control Invasive Grass Hot Spots In The Mojave Desert, Tanner Corless Smith

Theses and Dissertations

The social, economic, and ecological costs of plant invasions are vast, through their ability to alter ecosystem structure and function. Invasive annual grasses are a nuisance in the American Southwest through promotion of the grass-fire cycle. Annual grasses such as Bromus rubens, Bromus tectorum, Schismus barbatus, and Schismus arabicus have invaded the Mojave Desert and increased fire occurrence, thus it is important to identify and characterize the areas where persistent invasion has occurred and subsequently fire risk is increased by understanding the distribution of these invasive grasses. Previous plot and landscape-scale research has revealed anthropogenic and biophysical correlates with the …

Inhibition Of Cell Adhesion And Actin Localization During Migration Upon Protective Antigen Mutant Ligand Binding To The Capillary Morphogenesis Gene 2, Sai Lun Lee Apr 2022

Inhibition Of Cell Adhesion And Actin Localization During Migration Upon Protective Antigen Mutant Ligand Binding To The Capillary Morphogenesis Gene 2, Sai Lun Lee

Theses and Dissertations

Capillary Morphogenesis Gene 2 protein (CMG2) is a type 1 transmembrane receptor known as the anthrax toxin receptor 2 (ANTXR2). While it is documented that the cell surface receptor CMG2 mediates anthrax toxin entry into the cell via endocytosis, the physiological role of CMG2 is not well understood. Others have suggested that CMG2 may have a role in mediating ECM homeostasis and angiogenesis. Additionally, both anthrax protective antigen (PA) and a furin protease-resistant mutant, PASSSR, inhibit corneal neovascularization in a mouse model, and interestingly PASSSR has a greater affinity to CMG2 receptor. PASSSRalso has a more potent antiangiogenic effect than …

Settler-Author Allyship In Centering Indigenous Ecologies: Communal Will Through Collective Environmental Guilt In This Tender Land And Caleb's Crossing, Elena Marie Arana

Theses and Dissertations

The January 2021 edition of PMLA housed an entire cluster on "Indigenous Literatures and the Anthropocene," in which at least four of the eight non-Indigenous contributors directly addressed and supported a call for learning from and collaborating with Indigenous voices. The unanimity of the discussion dissolves somewhat drastically when considering exactly how this should be done, leading Melanie Taylor to voice one of the framing questions of the cluster: "If it is increasingly clear that not all members of Anthropos are equal drivers of the Anthropocene, and that not all are uniformly compromised by its havoc, how can we begin …

Physics-Guided Machine Learning In Ocean Acoustics Using Fisher Information, Michael Craig Mortenson Apr 2022

Physics-Guided Machine Learning In Ocean Acoustics Using Fisher Information, Michael Craig Mortenson

Theses and Dissertations

Waterborne acoustic signals carry information about the ocean environment. Ocean geoacoustic inversion is the task of estimating environmental parameters from received acoustic signals by matching the measured sound with the predictions of a physics-based model. A lower bound on the uncertainty associated with environmental parameter estimates, the Cramér-Rao bound, can be calculated from the Fisher information, which is dependent on derivatives of a physics-based model. Physics-based preconditioners circumvent the need for variable step sizes when computing numerical derivatives. This work explores the feasibility of using a neural network to perform geoacoustic inversion for environmental parameters and their associated uncertainties from …
