Book Review: Walter Scheidel. The Great Leveler: Violence And The History Of Inequality From The Stone Age To The Twenty-First Century, Leland Conley Barrows

Comparative Civilizations Review

Inspired by the work of Thomas Piketty, particularly his Capitalism in the Twenty-First Century (2013), and Albrecht Dürer’s 1497-1498 woodcut, “The Four Horsemen of the Apocalypse,” Dr. Walter Scheidel, Professor of Classics and History at Stanford University, argues in his massive 521-page volume that for most of human history reductions in socio-economic equality, supposedly a positive good, have resulted from more-or-less violent compressions entailing destruction and death. The implication is that in “normal” times, societies are characterized by inequality even though it is not perceived as a positive good.

What Constitutes Evidence For An Historical Explanation?, Kenneth Feigenbaum

Comparative Civilizations Review

What constitutes evidence for an historical explanation? What constitutes evidence for the explanations of the falls and rises of civilization? Better, what constitutes evidence for the best explanation of this phenomenon?

The purpose of this article is to acquaint the readers of the Comparative Civilizations Review with the work of a philosopher of history, Raymond Martin. In particular, I will present his approach on what constitutes how a decision should be made as to which explanation of an historical event is superior to another and why this is so.

Alegaatr The Bandit, Ethan Pedersen

Theses and Dissertations

One design strategy for developing intelligent agents is to create N distinct behaviors. At each time step during task execution, the agent, or bandit, chooses which of the N behaviors to use. Traditional bandit algorithms often (1) assume the environment is stationary, (2) focus on asymptotic performance, and (3) do not incorporate external information available to them. Each of these simplifications limits these algorithms such that they often cannot be used successfully in practice. In this paper, we propose a new algorithm, called AlegAATr, as a step toward overcoming these deficiencies. AlegAATr utilizes a technique called Assumption-Alignment Tracking (AAT), proposed …

The Rise Of Antisemitism In Germany, Susan M. Watts

Ballard Brief

Antisemitism has been rising in Germany since the country's reunification in the 1990s. In the modern day, antisemitism takes many forms, including hate speech, violent attacks, and anti-Jewish conspiracy theories. Although antisemitism has been rising in many parts of the world, Germany's history during the Holocaust causes its rise to be especially alarming to the Jewish community. The rise in antisemitism has been caused by the internet, current events like the pandemic and the Israel-Palestine conflict, and rightwing political extremism. Due to the rise in antisemitism, the fear of harassment and violence among Jews in Germany has risen, along with …

Undernutrition Among Children In Guatemala, Ellie Ostvig

Ballard Brief

Undernutrition in Guatemala is a serious issue that affects physical, mental, and social well-being. Children are most vulnerable to this dangerous condition, and in Guatemala, almost 50% of children experience inadequate growth and development due to a lack of appropriate nutrient intake. Because of food insecurity and lack of nutrients, young children do not have adequate access to the nutrition that they need. Guatemala is located in an area that makes it prone to natural disasters, which also contributes to the high rates of undernutrition. Undernourished children also experience intense disadvantages because of their weakened immune systems and cognitive underdevelopment. …

Tracing East Asian Librarianship In Correspondence: A Data Analysis Of Eastlib Messages From 1995 To 2020, Tang Li, Junjiro Nakatomi, Xiang Li

Journal of East Asian Libraries

The Eastlib listserv, established by the Council on East Asian Libraries (CEAL) as its official mailing list in the early 1990s and hosted at the University of North Carolina, Chapel Hill until the end of May 2022, has been the primary communication channel for East Asian librarians in North America for nearly 30 years. In 1999, Eastlib’s functionality was enhanced to allow its subscribers and the general public to browse and search through email discussions online. However, due to unanticipated system setting changes, it was discovered in March 2020 that access to the online Eastlib archive was limited to postings …

Exploration Of The Mechanisms Underlying Cortical Spreading Depolarizations Associated With Familial Hemiplegic Migraines, Brit Hepworth, Ryley Parrish

Library/Life Sciences Undergraduate Poster Competition 2023

Cortical Spreading Depolarization (CSD) - wave of cellular depolarization followed by wave of depression/inhibition • Familial Hemiplegic Migraine (FHM3) - monogenic subtype of migraine with aura; caused by Scn1A mutation, leading to gain-of-function of Nav1.1 (voltage gated sodium channel) • Hm1a - compound which potentiates the persistent current in Nav1.1; mimics the Scn1A gain-of-function mutation observed in patients with FHM3 • It is commonly hypothesized that CSDs are triggered via raised extracellular potassium, threshold for induction ~12mM • Modifications of Hm1a compound in development for treatment of Dravet Syndrome, but has been shown in a few cases to induce CSDs.

Identifying Deep Brain Photoreceptors In The Larval Zebrafish Optic Tectum, Emalie A. Christensen, Allison G. Pickens, Sarah Y. Jarrett, Maurice Hunt, Arminda Suli

Library/Life Sciences Undergraduate Poster Competition 2023

Deep brain photoreceptors (DBPs) are light sensing neurons present in mammals and non-mammalian vertebrates. In non-mammalian vertebrates, studies have shown DBP involvement in various time and light dependent behaviors including circadian rhythm, phototaxis, and seasonal reproduction. In adult teleosts, DBPs are present throughout the brain, including the optic tectum (OT). While their approximate location in teleosts is known, DBP’s function is relatively unknown. In this study, we focused on DBPs present in the larval zebrafish OT, a multilaminated midbrain structure responsible for multisensory integration. Single-cell RNA sequencing of the larval zebrafish OT showed the presence of several opsins. We focused …

Salty Genes: Rapid Discovery Of Salt Tolerance Genes In The Bacteria Kushneria, Andrew Jenkins, Brent Nielson, Jonathon T. Hill

Library/Life Sciences Undergraduate Poster Competition 2023

1st place poster design

Global rising levels of soil salinity have led researchers to seek microbial solutions to increase agricultural plant viability in high salt soils.

Kushneria increases growth of inoculated alfalfa in high salt soils, but little is known about how Kushneria survives in these environments1 or how it can be used to reduce the economic burden of salted soil.

Sootlib: A Soot Model Library For Combustion Simulation, Victoria B. Stephens, Joshua Bedwell, Alex J. Josephson, Keturah Oldham, David O. Lignell

Faculty Publications

Soot formation in combustion is an important process that affects radiative heat transfer, flame temperatures, and emissions with health and environmental impacts. Soot formation involves complex chemistry for nucleation, growth, oxidation, and coagulation processes. The soot particles vary widely in size and accurate modeling requires representation of the particle size distribution (PSD). Modeling soot is not trivial, and is only one of several physical processes active in combustion systems. This paper presents a software package called SootLib, which is an open-source library for modeling soot formation and other aerosol systems. SootLib is written in C++, is documented with Doxygen, and …

Developing Methods For Measuring In Vivo Lipid Metabolism, Russell L. Denton

Theses and Dissertations

Lipid metabolism is critically important to the normal function of individual cells and for signaling between tissues of the human body. There is a great need to quantify changes in lipid metabolism because of its implications in both normal healthy conditions and during disease development. In our first study, we developed a liquid chromatography mass spectrometry based workflow to assess in vivo metabolism of murine brain lipids. This involved sample preparation, data acquisition, and analysis software development and improvements. Regarding sample preparation, we maintained the mice at 5% body water for the duration of the experiment. As mouse metabolism proceeds, …

Turbulent Mixing Simulation Using The Hierarchical Parcel-Swapping (Hips) Model, Tommy Starick, Masoomeh Behrang, David O. Lignell, Heiko Schmidt, Alan R. Kerstein

Faculty Publications

Turbulent mixing is an omnipresent phenomenon that permanently affects our everyday life. Mixing processes also
plays an important role in many industrial applications. The full resolution of all relevant flow scales often poses a major challenge to the numerical simulation and requires a modeling of the small-scale effects. In transported Probability Density Function (PDF) methods, the simplified modeling of the molecular mixing is a known weak point. At this place, the Hierarchical Parcel-Swapping (HiPS) model developed by A.R. Kerstein [J. Stat. Phys. 153, 142-161 (2013)] represents a computationally efficient and novel turbulent mixing model. HiPS simulates the effects of turbulence …

Characterization Of Telsam Chaperone Linker To Improve Crystallization Resolution And Structural Elucidation Of The Hydrogenase Maturase Complex, Parag Laljibhai Gajjar

Theses and Dissertations

TELSAM crystallization can be a revolutionary tool for the facile crystallization of proteins. TELSAM can increase the rate of crystallization and form crystals at low protein concentrations without direct contact between TELSAM polymers and, in some cases, with very minimal crystal contacts overall. To further understand and characterize TELSAM crystallization, we sought to understand the requirements for the composition of the linker confirmation between TELSAM and the fused target protein. We evaluated four linkers, AlaAla, AlaVal, ThrVal, and ThrThr, between 1TEL and the human CMG2 vWa domain. We compared the number of successful crystallization conditions, the number of crystals, the …

Development Of The Tlvmie Force Field And A Standardized Methodology For Improved Pure-Component And Mixture Liquid Viscosity Predictions, Daniel J. Carlson

Theses and Dissertations

Existing viscosity prediction methods and relevant literature are reviewed. An exhaustive review of group contribution, corresponding states, and interpolative prediction methods finds that even the best of these models produces large prediction errors and often require significant experimental data. Molecular dynamics simulation techniques for viscosity prediction are evaluated and compared to one another to determine the best choice for this work. A thorough investigation finds that Equilibrium Molecular Dynamics (EMD) simulations are the best option for reproducible and reliable liquid viscosity predictions. The many tuning parameters available in molecular dynamics simulations are investigated for their effects on prediction uncertainty and …

Changes In The Mechanical Performance Of An Ortho-Planar Spring After Aging Tests, Lucas F. L. Santos, Larry L. Howell, Jose J. R. D’Almeida

Faculty Publications

This paper analyzed an ortho-planar spring (OPS) compliant mechanism and evaluated its mechanical performance after hygrothermal and ultraviolet radiation aging tests. The aging analysis performed here addresses the performance of compliant mechanisms after aging processes which can help inform the design of future compliant mechanisms. ASTM D638 tensile test type I samples were also submitted to aging to serve as a comparison for OPS samples. The samples were submitted to three different kinds of aging conditions, namely water immersion, oil immersion, and ultraviolet radiation. In conclusion, tensile samples showed significant statistical changes in Young's modulus and elongation at break, whereas …

Hard To Be Won: A Theatrical Interpretation Of Elizabeth Keckly’S “Behind The Scenes, Or Thirty Years A Slave And Four Years In The White House”, Selah Degering

Undergraduate Honors Theses

Hard to Be Won is a musical adaptation of a memoir by Elizabeth Keckly, a black woman of considerable success who earned the confidence of Abraham Lincoln and his wife, Mary, in war-torn 1860s America. My adaptation of this story showcases a new perspective: that of Elizabeth herself. Despite her memoir narrating these events in her own voice, Elizabeth as an individual has been largely ignored or misrepresented in modern, idealistic, and racially ignorant retellings and criticism. Elizabeth as a token black person in the narrative of the Lincoln household cannot stand as representation of this woman’s legacy when she …

Active Control Of Equilibrium, Near-Equilibrium, And Far-From-Equilibrium Colloidal Systems, Mark N. Mcdonald, Qinyu Zhu, Walter F. Paxton, Cameron K. Peterson, Douglas R. Tree

Faculty Publications

The development of top-down active control over bottom-up colloidal assembly processes has the potential to produce materials, surfaces, and objects with applications in a wide range of fields spanning from computing to materials science to biomedical engineering. In this review, we summarize recent progress in the field using a taxonomy based on how active control is used to guide assembly. We find there are three distinct scenarios: (1) navigating kinetic pathways to reach a desirable equilibrium state, (2) the creation of a desirable metastable, kinetically trapped, or kinetically arrested state, and (3) the creation of a desirable far-from-equilibrium state through …

The New Cd Set From Immortal Performances: Essential Listening, Henry Fogel

Journal of the Jussi Björling Societies of the USA & UK

Almost all performing artists exhibit differences between their studio recordings and their live performances (and, hopefully, also between different live performances). The degree of that difference can vary mightily from artist to artist. One tenor in whom this difference was very strongly pronounced was Jussi Björling. As fine as his studio recordings are, and some of them are extraordinary, the intensity and musical imagination he brought to live performances invariably increase compared with what we hear on his studio records. This remarkable compilation from Immortal Performances is essential listening for anyone who admires the great Swedish tenor. The three performances …

Healthcare Access Disparities Among Rural Populations In The United States, David Clove

Ballard Brief

In the United States, people living in rural areas face significant disparities in access to healthcare, quality of treatment, and the presence of chronic physical and mental ailments. Given their geographic isolation, it is relatively difficult for these individuals to seek emergency care, an issue that is exacerbated by socioeconomic gaps. These relationships flow in both directions-health and wealth often rise and fall in unison. Rural individuals also have to travel further to access healthcare, and the number of practitioners is sparse in comparison to metropolitan areas. Cultural and behavioral risks such as smoking, as well as the aforementioned shortage …

Period Poverty In The United States, Katie Krumperman

Ballard Brief

Period poverty is the lack of access to menstrual products and inadequate education surrounding menstruation. Period poverty affects menstruators worldwide, including those in the United States. In a 2019 study, 64% of menstruators noted that they struggled to afford menstrual products within the last year. Stemming from the cost of products, stigmas, education, and the world pandemic, those who menstruate struggle to afford menstruation products and have adequate education on the subject. The effects of period poverty include effects on menstruators' physical and mental health as well as their productivity at work. Lawmakers are fighting to end period poverty with …
