The Meanings Of The Millennium, Bernard J. Mcginn

The Thetean: A Student Journal for Scholarly Historical Writing

As we approach the year 2000-2001 of what we now ecumenically term the Common Era words like millennium and apocalypse seem to meet us everywhere. Millennial madness, as I call it, may be in large part a media event, but no age in Western history has lacked for those who believed that the end of history, which is what the word apocalypse signifies for most people, was near. While apocalypse conjures up images of dread and destruction in most minds, the history of the broader phenomenon of apocalypticism in Christianity, Judaism, and Islam, has always been an intricate fusion of …

Your Mission, Should You Choose To Attempt It, Is To Save The Mona Lisa! Gamification As A Method For Teaching Art, Caleb Ovard

Theses and Dissertations

To increase student engagement in their classroom, the author created an art curriculum using gamification methods that incorporates elements of tabletop role-playing games. The Role-playing Art Curriculum is a key element of this thesis. Possible research approaches involving game-based learning and gamification were examined to point toward future research and reflection regarding games and game-like content into an art curriculum. Action research methods were used to create and run the Role-playing Art Curriculum. The author concludes that the gamified curriculum took extra preparation and required more management to run then other traditional art curriculums.

An Advanced Sensor Network To Calculate Net Unit Heat Rate Of A Coal-Fired Boiler In Real-Time For Use In Dynamic Optimization, Keane Christopher Stewart

Theses and Dissertations

Dynamic operation of dispatchable energy sources is crucial for enabling the efficient integration of intermittent renewable energy into the electricity grid. Coal-fired boilers have been required to increase transient operation as renewable energy expands in order to avoid excess renewable energy going to waste. The frequent transient operation required to meet residual energy demand has created a challenge for coal-fired units to operate efficiently. This work utilizes an Advanced Sensor Network (ASN) to calculate Net Unit Heat Rate (NUHR) of a coal-fired boiler in real time through combustion calculations and statistical correlations to provide the tools for optimizing dynamic operation. …

Understanding The Origin, Evolution, And Dynamics Of Transneptunian Binaries, Benjamin C N Proudfoot

Theses and Dissertations

This dissertation discusses research that focuses on understanding transneptunian objects (TNOs) using a variety of techniques and approaches. In Chapter 1, I introduce the main concepts used throughout this dissertation and discuss the current understanding of the transneptunian region. In Chapter 2, I discuss my efforts to understand how Neptune's late stages of migration affect the Haumea family, the only known collisional family in the transneptunian region. Using advanced simulations of Neptune migration, I find that the Haumea family can plausibly form before the termination of giant planet migration and show that this extensively mixes the family. The simplest explanation …

From Congregations To Candidates: How Religion Explains The Partisan Gender Gap In State Legislatures, Ashlan Gruwell

Undergraduate Honors Theses

While much has been said about both the gender gap and partisan gender gap in representation in Congress and state legislatures, most of this research ignores the critical role of religion as an explanatory variable. I propose a new theory where the presence of a high proportion of evangelical Protestants in the electorate explains both the gender gap in representation that has long existed as well as the emergence of a partisan gap among women in state legislatures. As evangelical Protestants became politicized and flocked to the Republican Party in the 1980s and 1990s, more Democratic women were elected and …

Progress Towards The Development Of Asymmetric Conditions For Intramolecular Heteroatom/Dehydro-Diels-Alder Reactions For Synthesizing Furo[3,4-C] Pyranones And Anticancer Podophyllotoxins, Peter Mpaata

Theses and Dissertations

Furo[3,4-c] pyranone is a unique bicyclic molecular structure found in bioactive sesquiterpene isobolivianine and in artificial cytotoxic stilbene derivatives. The structure of furo[3,4-c] pyranone is analogous to cyclopenta[c] pyran structure found in potent cytotoxic iridoids like catapol. Chiral substrates for intramolecular hetero-Diels-Alder (IHDA) reaction have been synthesized in yields ranging from 39% to 81%. These compounds undergo [4+2] cycloaddition via ambimodal/ bispericyclic process to give a mixture of furo[3,4-c] pyranone in yields ranging 40-70% and aryl tetralin lactone derivatives. Density functional theory (DFT) calculations have been performed to gain insight into the mechanism leading to the formation of these compounds. …

Optimal Method To Obtain Soil Strength Properties In Sands For Laterally Loaded Pile Analysis In Lpile, Troy Roger Washburn

Theses and Dissertations

One common software program developed for analyzing single laterally loaded piles is called LPILE. Soil properties are required as input into LPILE. For sands, the soil properties required are effective soil unit weight, γ’; subgrade modulus, k; and the internal friction angle, ϕ’. There are two commonly used methods to obtain ϕ’ and subsequently k: the API method and Bolton method. Fourteen different pile test sites were used in the analysis of the API and Bolton methods to obtain soil strength properties in sands for laterally loaded single pile tests. Between the fourteen pile test sites, a total of 26 …

Local Atomic And Magnetic Structure Of Multiferroic (Sr,Ba)(Mn,Ti)O3, Braedon Jones

Theses and Dissertations

We present a detailed study of the local atomic and magnetic structure of the type-I multiferroic perovskite system (Sr,Ba)(Mn,Ti)O3 using x-ray and neutron pair distribution function (PDF) analysis, polarized neutron scattering, and muon spin relaxation (μSR) techniques. The atomic PDF analysis reveals widespread nanoscale tetragonal distortions of the crystal structure even in the paraelectric phase with average cubic symmetry, corresponding to incipient ferroelectricity in the local structure. Magnetic PDF analysis, polarized neutron scattering, and μSR likewise confirm the presence of short-range antiferromagnetic correlations in the paramagnetic state, which grow in magnitude as the temperature approaches the magnetic transition. We show …

Motives And Methodologies For Improving 3d Displays, Dylan Charles Barton

Theses and Dissertations

This work contains two key contributions to the development of 3D displays. First a successful exploratory human trial research study. By comparing multiple real displays in human trials, the factors of ease of use, time, and accuracy were able to be examined in a general setting, instead of isolated to only a specific type of 3D display. These human tests showed that 3D displays in general offer better ease of use and accuracy compared to 2D displays when showing 3D media. This differs from previous studies where only a single display was examined or theoretical papers discussing factors on paper. …

The large cache of scrolls from Herculaneum were opened to scholars in spite of and because of the destruction of the volcano and damaging unfurling techniques. The fragments inherited have been studied closely by scholars. Digitization and technological work on the Herculaneum papyri, including the important infrared imaging completed by BYU in the early 2000s, and the 3-D imaging and inchoate virtual unwrapping technology by EduceLab, have amplified and aided scholarship on the scrolls and will continue to do so. P.Herc. 817 is a unique Latin text within the collection that has been heavily studied by scholars due to its …

Revisiting Marshallese Causative Constructions Using Lexical Aspect, Damon Hatch Swain

Theses and Dissertations

This thesis reexamines causative constructions found in Marshallese; an Austronesian language spoken in the Republic of the Marshall Islands. Both Bender, Capelle & Pagotto (2016) and Willson (2008) hint that lexical aspect is a necessary predictor of causative behaviors in Marshallese, but offer no explanations. The primary focus of this thesis is to examine lexical aspect's influence on causative derivations. This project shows that Marshallese stative verbs display two distinct causative constructions: stative causatives and causative abstract nouns. The Marshallese causative prefix, ka-, tends to exhibit common crosslinguistic patterns of causative constructions as laid out by Dixon and Aikenvald (2000). …

Assuring Netlist-To-Bitstream Equivalence Using Physical Netlist Generation And Structural Comparison, Reilly Mckendrick, Jeffrey Goeders, Keenan Faulkner

Faculty Publications

Hardware netlists are generally converted into a bitstream and loaded onto an FPGA board through vendor-provided tools. Due to the proprietary nature of these tools, it is up to the designer to trust the validity of the design’s conversion to bitstream. However, motivated attackers may alter the CAD tools’ integrity or manipulate the stored bitstream with the intent to disrupt the functionality of the design. This paper proposes a new method to prove functional equivalence between a synthesized netlist, and the produced FPGA bitstream. The novel approach is comprised of two phases: first, we show how we can utilize implementation …

This transformation sought to address this gap, recognizing the increasing significance of online education in adapting to unforeseen challenges such as the COVID-19 pandemic and aligning with the advancements in the global educational landscape.

Finding Words For God: Poetic Foraging In Louise Glück's The Wild Iris, Rachel Cardall

Theses and Dissertations

The primary speaker of Louise Glück's The Wild Iris is a wanderer in her own garden. She relentlessly searches for God among her foxgloves and daisies, straining to hear God's voice. Two other speakers, God and the collective plants of the garden, offer their perspectives without acknowledgement by the human speaker. Many critics read these two other speakers as, in fact, narcissistic projections of the human speaker, a God and a world made in her own image. In this thesis, I clarify that the kind of narcissistic projection that occurs in The Wild Iris is actually productive for genuine spiritual …

Development Of Battery-Grade Silicon Through Magnesiothermic Reduction Of Halloysite-Derived Silica, Nathan Clarke

Theses and Dissertations

The production of halloysite-derived silicon (HDS) is investigated as a potential anode material in lithium-ion batteries (LIBs). Other researchers have found HDS to be electrochemically active in small test cells. To test larger electrochemical cells, the production process needs to be scaled up and optimized. HDS is produced through magnesiothermic reduction of acid-etched halloysite. The reduction process is very exothermic and requires special consideration while being scaled up. A reactor and pressure release system were designed and fabricated to perform the reduction process in a safe manner. Various steps of the process were tested to determine their influence on the …

Void Formation And Mortality During Liquid Composite Molding, Jared Michael Turner

Theses and Dissertations

Within the high-performance composite manufacturing industry, there exists a need to improve the reliability of LCM (Liquid Composite Molding) manufacturing processes in producing composite parts that better approach the quality and consistency of pre-impregnated composite tapes that are cured in autoclaves with cost being a driving factor of this need. One obstacle to that end is the phenomenon of void formation during the LCM infusion processes. The formation of these voids through different mechanisms leads to composite parts with lower mechanical properties and consistency than their pre-impregnated autoclave cure counterparts. The objective of this research is to investigate the different …

Characterizing Quirky Signals, Joshua D. Forsyth

Theses and Dissertations

Large collider facilities such as the Large Hadron Collider (LHC) employ a variety of search methods in hopes of finding new particles. It may be that new physics beyond the SM is waiting to be discovered at energies accessible to the LHC. Quirks are particles charged under a new confining gauge group with masses much larger than their confinement scale. This project details the dynamics of quirks, as well as the production and decay of electrically charged bound states of scalar quirks. The cross section for these states is compared to existing Wγ resonance searches at the LHC. Such a …

The Experience Of Teaching Disengaged Students In Stem: Examined Through The Lens Of The Abc Engagement Framework, William Randall Hjorth

Theses and Dissertations

Young people today are increasingly disengaged from their education. Studies indicate that of all school subjects, American students struggle to engage in STEM subjects more than others. For decades, we have known that student engagement/disengagement impacts teachers. Researchers have also claimed that engagement/disengagement can be described as a construct made up of affective, behavioral, and cognitive dimensions (ABC). However, we do not understand how teachers experience student disengagement in these three areas. At a crucial time in education, investigation into the experiences of teachers with disengaged students is needed to uncover insights which may help us understand how teachers interpret …

In-Depth Geochemical Analysis Of Turbidite-Associated Shales Of The Pindos Basin, Greece, Jonathon Michael Sevy

Theses and Dissertations

Detailed geochemical analysis of the turbidite-associated shales of the Cretaceous Katafito Formation, Greece, reveals important details regarding the paleoenvironment, paleoproductivity, and regional tectonics of the Pindos Basin. The Katafito Formation was deposited along an active margin at the early onset of closure of the Tethys Sea in the Pindos sub-basin. While careful studies of the coarse clastic component of turbidites are common, this study consisted of a detailed geochemical characterization of the fine-grained portions, which helped reveal paleoenvironmental information about the basin. This study combined organic and inorganic geochemistry utilizing elemental, mineralogical, and organic chemical signatures from fine-grained turbidite-associated sediments …

Age At First Marriage And Marital Success In The Context Of Stress Theory: An Updated Investigation With A Longitudinal, Nationally Representative Sample, Anne Marie Wright Jones

Theses and Dissertations

The purpose of this study is to use family stress theory to examine the relationship between age at first marriage and marital quality and divorce. Age at marriage continues to increase and the demographics keep changing. Past research suggests that early age at marriage has been a contributing factor to divorce risk. Marital quality outcomes can also give us an idea of how well couples are faring in their marriages. This study employs a sample from a longitudinal, nationally representative investigation (CREATE), which has followed newlywed couples since 2016. The sub-sample for this study comes from wave one and includes …

Pullout Strength Of Welded Wire And Ribbed Strip Reinforcement In Lightweight Cellular Concrete Backfill Behind Mechanically Stabilized Earth Wall, Mathew Robert Bueckers

Theses and Dissertations

Lightweight cellular concrete (LCC) is a cement, water, and air entrained mixture that consists of 25-80% voids. The air voids reduce the material strength but also decrease the material weight. Due to its lightweight properties LCC is an attractive alternative to soil backfill for retained structures, such as mechanically stabilized earth (MSE) walls. Although LCC is widely used behind MSE walls, limited information exists regarding the pullout strength of MSE wall reinforcements in LCC backfill. This research attempts to fill the knowledge gap through performing pullout tests on welded wire and ribbed strip reinforcements in MSE walls to determine the …

Student Works

The purpose of this literary review is to explore how psychological and acute stress affect the academic abilities of college students. We will explore the effects of stress and how they directly impair the academic, social, emotional, and mental well-being of college students in the United States.. This can be seen as you observe and study what stress looks like on a college student. It is found that over 1⁄3 of most universities have students that struggle with intense stress. Often, students do not know or understand how to cope. This lack of knowledge can stem from their childhood, where …

Design And Fabrication Of Transparent Ultrasonic Transducers For Optoelectronic Applications, Stephen Colby Warren

Theses and Dissertations

Acoustic levitation utilizes general principles of ultrasonics to trap particles in midair without external support. This is done by creating an array of ultrasonic transducers to propagate sound waves to a focused point in space. In order to optimize the particle trap it is necessary to design transducers that can produce enough sound to create pressure pockets. In this work I examine the fundamental principles of acoustics by testing the sound pressure levels (SPL) of a known transducer in both air and water mediums. A comparison between domed and bimorphed transducers are also examined. Experimentation was performed on the feasibility …

The participants included two third-grade teachers and two fourth-grade teachers engaged in an alternative PLC process during their collaboration time. Interviews were conducted and focused on how the teachers thought about student thinking as the driving force of their collaboration. The teachers found their PLC time was more focused, student thinking led the discussions and lessons, they were more responsive to student needs, and their own mathematical understanding increased. The teachers also …

Evaluation Of Unmanned Aerial Vehicle Flight Parameters That Impact Stockpile Volume Computations, Nicole Marie Hastings

Theses and Dissertations

Stockpile volumes are monitored by their companies as the product (i.e., aggregate, soil) is moved in and out of the facilities to ensure minimal product loss. Companies are mandated to report product movement to the government to ensure that the aggregate and soil is going where it is supposed to go. Many tools are used to monitor stockpile volumes including truck scales (to weigh incoming and outgoing trucks), light detection and ranging (LiDAR), Global Navigation Satellite System (GNSS) equipment, and unmanned aerial vehicle (UAV) photogrammetry. These processes give a good estimate of stockpile volumes. Errors in these estimates typically come …

The researchers observed three types of training: self-training, didactic training through a pre-recorded lesson, and one-on-one training. A repeated acquisition single case design across participants was used along with a control group. The participants included nine parents from the surrounding areas of Brigham Young University who were randomly selected for either the intervention group or the control group. Four of the five participants in the intervention or treatment group achieved mastery once they received didactic …

Dynamic Segmental Kinematics Of The Lumbar Spine During Diagnostic Movements, Paul Mcmullin

Theses and Dissertations

While lumbar kinematics can be measured in vivo, most measurements are invasive (such as percutaneous bone pins), provide high doses of radiation (such as biplane fluoroscopy), or are taken with the patient in a static position (such as MRIs). Recent work suggests that lumbar kinematics can be determined by dynamic measurements of epidermal strain in the lower back. This work aims to develop and examine a method of examining lumbar kinematics via optoelectronic motion capture utilizing skin-mounted markers in the lumbar region. Two studies were performed. One study examined lumbar epidermal strain in 28 asymptomatic subjects during diagnostic movements, while …
