“To Moderate And Unify” The Role That Latter-Day Saint Citizen-Rhetors Can Play In Healing American Political Discourse, Kristine Hansen Jan 2022

“To Moderate And Unify” The Role That Latter-Day Saint Citizen-Rhetors Can Play In Healing American Political Discourse, Kristine Hansen

BYU Studies

In the April 1997 general conference of The Church of Jesus Christ of Latter-day Saints, then-Elder Henry B. Eyring stated, “When the words of prophets seem repetitive, that should rivet our attention.” Repetition, he asserted, means the Lord’s servants are “warning the people, telling them the way to safety.” In both the October 2020 and the April 2021 general conferences, President Dallin H. Oaks stressed the importance of the rule of law and the best ways to participate as citizens in political processes. Although he focused on the United States, President Oaks reassured his global audience that the principles he …

"The Least Of These", Tinesha Zandamela Jan 2022

"The Least Of These", Tinesha Zandamela

BYU Studies

While imprisoned in Birmingham, Dr. Martin Luther King Jr. wrote of the struggle for civil rights: “I am cognizant of the interrelated- ness of all communities and states. I cannot sit idly by in Atlanta and not be concerned about what happens in Birmingham. Injustice anywhere is a threat to justice everywhere. We are caught in an inescapable network of mutuality, tied in a single garment of destiny. Whatever affects one directly affects all indirectly.”

On Being A Disciple Of Hope, Jessica Robinson Preece Jan 2022

On Being A Disciple Of Hope, Jessica Robinson Preece

BYU Studies

I am a political scientist, which means that I study patterns in politics. Most of the patterns in politics that I study are patterns of sexism. I work to accurately measure and carefully describe patterns of sexism in how political parties recruit candidates, how voters vote, how we deliberate with each other, or how Congress operates. Some of my work even identifies sexism in the methods other political scientists have used to study these topics in the past. On top of that, as a professor, I spend a significant part of my workday introducing these and other patterns of sexism …

The Saints And The State: The Mormon Troubles In Illinois, James Simeone, Brent M. Rogers, Reviewer Jan 2022

The Saints And The State: The Mormon Troubles In Illinois, James Simeone, Brent M. Rogers, Reviewer

BYU Studies

The history of the Latter-day Saint experience in Nauvoo, Illinois, still has a great deal to teach us. It is not just the simplistic story of religious persecution and expulsion that is often rehearsed. In seven dense chapters, James Simeone, professor of political science at Illinois Wesleyan University, unveils a complex political milieu to explain the tension that led to the 1846 departure of the Saints from Illinois—and ultimately the United States. Relying on political theory and philosophy and his deep knowledge of politics in frontier Illinois, Simeone unpacks the paradox of a developing democracy, which he defines as the …

Khovanov Homology & Uniqueness Of Surfaces In The 4-Ball, Isaac Sundberg Jan 2022

Khovanov Homology & Uniqueness Of Surfaces In The 4-Ball, Isaac Sundberg

Bryn Mawr College Dissertations and Theses

We use the functoriality of Khovanov homology to examine the smooth, boundary-preserving isotopy of surfaces embedded in the 4-ball. We exemplify an infinite family of prime knots that bound an arbitrarily-large number of smoothly-distinct slice disks by distinguishing the maps they induce on Khovanov homology. Similar techniques produce an infinite family of knots that each bound a pair of exotic surfaces of arbitrary genus.

Tracing The Evolution Of Welfare Discourse From 1990 To 2016, Jenifer A. Norton Jan 2022

Tracing The Evolution Of Welfare Discourse From 1990 To 2016, Jenifer A. Norton

Bryn Mawr College Dissertations and Theses

In August 1996, Temporary Assistance for Needy Families (TANF) replaced Aid to Families with Dependent Children (AFDC) as the primary cash welfare program for single mothers and children. A political debate during the early to mid-1990s that was particularly hard on welfare recipients culminated in a block grant to states tied to mandatory work requirements and time-limited lifetime benefits for recipients. Media coverage during this period closely tracked the unfolding political discourse around welfare reform and recipients. Following TANF’s implementation, though, coverage dwindled to near nonexistent levels. At this writing in early 2022, TANF remains part of the social safety …

Biology Faculty Research and Scholarship

Understanding patterns and drivers of species distribution and abundance, and thus biodiversity, is a core goal of ecology. Despite advances in recent decades, research into these patterns and processes is currently limited by a lack of standardized, high-quality, empirical data that span large spatial scales and long time periods. The NEON fills this gap by providing freely available observational data that are generated during robust and consistent organismal sampling of several sentinel taxonomic groups within 81 sites distributed across the United States and will be collected for at least 30 years. The breadth and scope of these data provide a …

Synthesis Of Highly Reactive Sulfone Iminium Fluorides And Their Use In Deoxyfluorination And Sulfur Fluoride Exchange Chemistry, James A. Vogel, Rania Hammami, Ara Ko, Hiya Datta, Yael N. Eiben, Karley J. Labenne, Ellis C. Mccarver, Ebrar Z. Yilmaz, Patrick R. Melvin Jan 2022

Synthesis Of Highly Reactive Sulfone Iminium Fluorides And Their Use In Deoxyfluorination And Sulfur Fluoride Exchange Chemistry, James A. Vogel, Rania Hammami, Ara Ko, Hiya Datta, Yael N. Eiben, Karley J. Labenne, Ellis C. Mccarver, Ebrar Z. Yilmaz, Patrick R. Melvin

Chemistry Faculty Research and Scholarship

We report the synthesis of sulfone iminium fluorides (SIFs), a reactive class of sulfur(VI) molecules. The synthesis is tolerant of a variety of substituents on the sulfur and nitrogen components. The SIF reagents were applied to the deoxyfluorination of alcohols and carboxylic acids, providing high yields of fluorinated products in 60 s at room temperature. The SIF reagents were then utilized in sulfur fluoride exchange (SuFEx), creating the first ionic SuFEx products to date.

Rapid Radiation Of Zeiformes Revealed Through Comparison Of Jaw Morphologies, Jeffrey Peters Jan 2022

Rapid Radiation Of Zeiformes Revealed Through Comparison Of Jaw Morphologies, Jeffrey Peters

Master's Theses

Zeiformes (e.g., Dories, Lookdown dories, Tinselfishes, Oreos) are a deep (1000 m) to mid-water (100 m) marine order of acanthomorph fishes with a circumpolar distribution, and a fossil record extending back to the Late Cretaceous. The order consists of 33 species across six families. The phylogenetic placement of the Zeiformes within Teleostei has been debated, but more recent studies based on both molecular and morphological data place Zeiforms within Paracanthopterygii closely related to Gadiformes. Zeiformes are characterized by anal and dorsal profiles that contain a variable number of fin rays and spines. They are mostly deep bodied, highly compressed fishes …

The Implementation Of Restorative Justice Practices: An Exploration Into Administrators' Experiences, Sacha Starr Helling-Christy Jan 2022

The Implementation Of Restorative Justice Practices: An Exploration Into Administrators' Experiences, Sacha Starr Helling-Christy

Education Dissertations

In this paper, transformative learning theory and restorative justice practices, as well as the empirical research done to link theory to practice, are explored. As Mezirow (2018) stated, transformative learning is “the process by which we transform problematic frames of reference (mindsets, habits of mind, meaning perspectives)—sets of assumption and expectation—to make them more inclusive, . . . open, reflective and emotionally able to change” (p. 116). In other words, people’s life experiences help shape their opinions and worldviews, and most people are resistant to change these ideas the more solidly they are planted in one’s minds as being correct. …

Oncogenic Gq/11 Signaling Acutely Drives And Chronically Sustains Metabolic Reprogramming In Uveal Melanoma, Michael D Onken, Sarah E Noda, Kevin M Kaltenbronn, Cheryl Frankfater, Carol M Makepeace, Nikki Fettig, Kisha D Piggott, Philip L Custer, Joseph E Ippolito, Kendall J Blumer Jan 2022

Oncogenic Gq/11 Signaling Acutely Drives And Chronically Sustains Metabolic Reprogramming In Uveal Melanoma, Michael D Onken, Sarah E Noda, Kevin M Kaltenbronn, Cheryl Frankfater, Carol M Makepeace, Nikki Fettig, Kisha D Piggott, Philip L Custer, Joseph E Ippolito, Kendall J Blumer

Open Access Publications

Metabolic reprogramming has been shown to occur in uveal melanoma (UM), the most common intraocular tumor in adults. Mechanisms driving metabolic reprogramming in UM are poorly understood. Elucidation of these mechanisms could inform development of new therapeutic strategies for metastatic UM, which has poor prognosis because existing therapies are ineffective. Here, we determined whether metabolic reprogramming is driven by constitutively active mutant α-subunits of the heterotrimeric G proteins Gq or G11 (Gq/11), the oncogenic drivers in ∼90% of UM patients. Using PET-computed tomography imaging, microphysiometry, and GC/MS, we found that inhibition of oncogenic Gq/11 with the small molecule FR900359 (FR) …

Identification And Dosimetry Of Irradiated Pistachio (Pistacia Vera L.) Using Epr, Elsayed Salama, Ahmed M. Maghrabya, Samy A. Anwar, M. El-Sayed Jan 2022

Identification And Dosimetry Of Irradiated Pistachio (Pistacia Vera L.) Using Epr, Elsayed Salama, Ahmed M. Maghrabya, Samy A. Anwar, M. El-Sayed

Basic Science Engineering

In the current study, the EPR signal of both gamma-irradiated shell and kernel of the pistachio is recorded and investigated. The spectrum properties, microwave power dependency of signal intensities, short- and long-term temporal dependencies, and other significant factors are studied. This investigation was done on how varying radiation doses (0–10 kGy) affected the reactions of pistachio shells and kernels. The time dependence of the radiation-induced signal intensity of pistachio showed that the maximum intensity reached about 98.75% and 67% of its original value for shells and kernels, respectively, after the first six hours. These results indicate that EPR is an …

Extreme Temperatures During Pregnancy And Adverse Birth Outcomes: Evidence From 2009 To 2018 U.S. National Birth Data, Gulcan Cil, Jiyoon Kim Jan 2022

Extreme Temperatures During Pregnancy And Adverse Birth Outcomes: Evidence From 2009 To 2018 U.S. National Birth Data, Gulcan Cil, Jiyoon Kim

Economics Faculty Research and Scholarship

We provide the first estimates of the impacts of prenatal exposure to extreme temperatures on infant health at birth using the latest national birth data from 2009 to 2018 from all U.S. states. We consistently find that an additional day with mean temperature greater than 80°F or less than 10°F increases preterm births and low birthweight. Strikingly, the adverse effects are borne disproportionately by Black and Hispanic mothers, suggesting that the projected increase in extreme temperatures may further exacerbate the existing birth health disparities across different race/ethnicity groups. We also contribute by investigating the impact of deviations from the normal …

Goethe’S Faust And The Philosophy Of Money, Thimo Heisenberg Jan 2022

Goethe’S Faust And The Philosophy Of Money, Thimo Heisenberg

Philosophy Faculty Research and Scholarship

Philosophers today do not think of Goethe’s Faust as an important contribution to the philosophy of money. But to discount the work in this way is a mistake, I argue. Underneath Faust’s lyrical form, Goethe develops a comprehensive view of money that came to be an important influence on left-wing (Karl Marx) and right-wing (Oswald Spengler) discussions of money. Centrally, Goethe argues that modern economic practices have transformed money obsession (long conceived of primarily as an individual vice) into a structural problem: social structures are now set up to systematically require individuals to engage in quasi-obsessive behaviors towards …

Fichte And Hegel On Free Time, Thimo Heisenberg Jan 2022

Fichte And Hegel On Free Time, Thimo Heisenberg

Philosophy Faculty Research and Scholarship

To us today, it seems intuitive that an ideal society would secure for its citizens some time for leisure that is, some time to do “whatever they want” after having attended to their various responsibilities and natural needs. But, in this essay, I argue that—in 19th century social philosophy—the status of leisure (Muße) in an ideal society was actually surprisingly controversial: whereas J.G. Fichte makes a strong case for leisure as part of an ideal society (going even so far as considering it its central good), G.W.F. Hegel implicitly argues against this idea. For him, leisure is …

History Faculty Research and Scholarship

Drawing on oral traditions and archival materials, this article examines the validity of claims made by the French colonial physicians and administrators that the African patients’ mistrust of and resistance to biomedicine had to do with their superstition, apathy, and ignorance, as well as with the pressure exercised upon them by healers, marabouts, and midwives. It argues that the African patients’ therapeutic choices were rational and were informed by their cultural history.

Realizing van der Waals (vdW) epitaxy in the 1980s represents a breakthrough that circumvents the stringent lattice matching and processing compatibility requirements in conventional covalent heteroepitaxy. However, due to the weak vdW interactions, there is little control over film qualities by the substrate. Typically, discrete domains with a spread of misorientation angles are formed, limiting the applicability of vdW epitaxy. Here, the epitaxial growth of monocrystalline, covalent Cr5Te8 2D crystals on monolayer vdW WSe2 by chemical vapor deposition is reported, driven by interfacial dative bond formation. The lattice of Cr5Te8, with a lateral dimension of a few tens of micrometers, …

Bending Waves Excited By Irregular Gas Inflow Along Warps, Tigran Khachaturyants, Leandro Beraldo E Silva, Victor P. Debattista, Kathryne J. Daniel

Physics Faculty Research and Scholarship

Gaia has revealed clear evidence of bending waves in the vertical kinematics of stars in the solar neighbourhood. We study bending waves in two simulations, one warped, with the warp due to misaligned gas inflow, and the other unwarped. We find slow, retrograde bending waves in both models, with the ones in the warped model having larger amplitudes. We also find fast, prograde bending waves. Prograde bending waves in the unwarped model are very weak, in agreement with the expectation that these waves should decay on short, approximately crossing, time-scales, due to strong winding. However, prograde bending waves are much …

Physics Faculty Research and Scholarship

Persistent photoresponses require optical excitations to metastable states, which are rare of ionic origin due to the indirect photon-ion interaction. In this work, we explore the photoinduced metastable proton states in the proton-transfer type molecular ferroelectric croconic acid. We observe that, after the photoexcitation, the changes of structural and ferroelectric properties relax in ∼10^3s, indicating persistent photoresponses of ionic origin. In contrast, the photoconductivity relaxes within 1 s. The 10^3s timescale suggests that the ionic metastable states result from proton transfer both along and out of the hydrogen bonds. This discovery unveils an ionic mechanism for the phototunability, which offers …

Impact Of The Electron Density And Temperature Gradient On Drift-Wave Turbulence In The Large Plasma Device, Conor Perks, Saskia Mordijck, Troy Carter, Bart Van Compernolle, Stephen Vincena, Giovanni Rossi, David A. Schaffner Jan 2022

Impact Of The Electron Density And Temperature Gradient On Drift-Wave Turbulence In The Large Plasma Device, Conor Perks, Saskia Mordijck, Troy Carter, Bart Van Compernolle, Stephen Vincena, Giovanni Rossi, David A. Schaffner

Physics Faculty Research and Scholarship

In this paper we present an experimental study of edge turbulence in the Large Plasma Device at UCLA. We utilize a scan of discharge power and prefill pressure (neutral density) to show experimentally that turbulent density fluctuations decrease with decreasing density gradient, as predicted for resistive drift-wave turbulence (RDWT). As expected for RDWT, we observe that the cross-phase between the density and potential fluctuations is close to 0. Moreover, the addition of an electron temperature gradient leads to a reduction in the amplitude of the density fluctuations, as expected for RDWT. However, counter to theoretical expectations, we find that the …

Physics Faculty Research and Scholarship

Antiferromagnetically (AFM) coupled skyrmions offer potential advantages for spintronic devices, including reduced dipolar fields that may enable smaller skyrmion sizes and a reduction of the skyrmion Hall effect. However, the topological stability of AFM-coupled skyrmions subjected to dramatic spin deformation through low-temperature cycling has not been investigated. Here we report the discovery of a topological spin memory effect for AFM-coupled skyrmion pairs in [Co/Gd/Pt]10 multilayered films. Photoemission electron microscopy imaging shows that bubble skyrmions in the multilayer that are stable at room temperature evolve into complex in-plane spin textures as the temperature is lowered and reform completely when the sample …

We report on the formation of Néel-type magnetic bubble skyrmions at room temperature in [Pt/Co/Ir]3 multilayered thin films after an in-plane magnetic field treatment. Polar magneto-optical Kerr Effect (p-MOKE) microscopy images show that the dendritic magnetic configurations observed after AC demagnetization evolve into magnetic bubble skyrmions after the application and subsequent removal of an in-plane magnetic field. Micromagnetic simulations were used to systematically investigate the role of the in-plane magnetic field magnitude, misalignment of the sample, and the Dzyaloshinskii-Moriya interactions (DMI) in generating bubble skyrmions during the field treatment. The simulations show that in-plane fields slightly below the saturation field …
