Where Evidence-Based Research Meets L2 Pedagogy: Classroom Instruction Of Russian Case Morphology, Ryder L. Myrick

Senior Theses

Learners of Russian as a second language (L2) have long been documented to struggle with the Russian case system. However, pedagogy-oriented research on the acquisition of Russian case morphology remains limited. Addressing this gap, the current classroom-based and theoretically-motivated study reports a partial replication of Kisselev, Rubina and McManus (2025) with the addition of a delayed post-test, tutoring sessions, and improved materials. Quantitative findings match those of the original study, further supporting the effectiveness of Usage-Based instruction in Russian case pedagogy (90% average experimental-group score and 66% control-group score on a post-test). Qualitative analysis reveals additional factors shaping learning outcomes, …

America’S First Comic Role, “The Negro”: An Analysis Of Historical Caricatures And Their Influence On African American Characters And Archetypes, Skyla A. Praylow

Senior Theses

A stereotype is defined as “a set of ideas that people have about what someone or something is like, especially an idea that is wrong.”1 Even though stereotypes are understood to be harmful, “contributing to prejudice and discrimination,” they are still believed to have some “kernel of truth,” and are viewed as “overgeneralized beliefs about social groups in society.” These stereotypes are then used as propaganda to reinforce oppressive systems in the US.2 Stereotypes create the basis of opinions that are used to create caricatures. A caricature is “a picture, description, or imitation of a person in which certain striking …

Suture Augmentation With Ucl Repairs In Baseball Pitchers As An Alternate To Reconstructions: An Evidence-To-Practice Review, Kayleigh A. De Koker, Kenneth E. Games

Clinical Practice in Athletic Training

An injury to the ulnar collateral ligament (UCL) is sustained through repetitive valgus motions, increasing in prevalence across all levels of baseball due to the increasing workload demands placed on the medial elbow in pitching. Traditionally, UCL tears have been managed through reconstructions followed by a lengthy rehabilitation process. In recent years, the UCL repair with suture augmentation has gained favor given the enhanced patient and clinician outcomes in return-to-play timelines, decreased medial gapping, improved Kerlan Jobe Orthopedic Clinic (KJOC) scores, and long-term functionality. Utilizing 4 databases (MEDLINE, Embase Cochrane library, Science Direct, and Scopus), literature was obtained addressing the …

Regulation Of Zygotic Genome Activation By The Nucleocytoplasmic Ratio, Lily Acker, Hui Chen

Faculty Publications

During early development, embryos undergo the maternal-to-zygotic transition (MZT), when control of development shifts from maternal factors to the newly activated zygotic genome. Decades of studies in various model organisms suggest that the nucleocytoplasmic (N/C) ratio is a key regulator of zygotic genome activation (ZGA), though this relationship is more nuanced in some organisms than others. Changing the nuclear content, nucleus size or cell size has been shown to shift the timing of ZGA. Mechanistically, the N/C ratio is linked to fundamental cellular processes that regulate genome activities, including nuclear import, repressor titration, activator accumulation, cell cycle lengthening, and chromatin …

Multiscale Computational Modeling Of The Cardiopulmonary Consequences Of Postnatal Hyperoxia With Implications For Preterm-Born Children, Salla M. Kim, Filip Jezek, Pim J. A. Oomen, Gregory P. Barton, Feng Gu, Daniel A. Beard, Kara N. Goss, Mitchel J. Colebank, Naomi C. Chesler

Faculty Publications

Moderate to extreme preterm birth (<  32 weeks gestation) affects cardiopulmonary structure and function and is associated with increased risk of heart failure through adulthood. The rat hyperoxia (Hx) model (term born; postnatal Hx exposure) captures biventricular changes, including at the cell and organ scale, and pulmonary vascular remodeling seen in preterm humans. However, synthesizing these measures across scales and organ systems is challenging. We hypothesized that in silico modeling of biventricular mitochondrial, myofiber, and organ-scale function plus circulatory function could capture key features of cardiopulmonary abnormalities due to preterm birth. Therefore, we calibrated a multiscale model to subject-specific biventricular pressure–volume data previously obtained from Hx rats alongside normoxic (Nx) controls to investigate the abnormalities in cardiopulmonary function at multiple scales in this animal model of human preterm birth. The calibrated model demonstrates excellent agreement with the data and captures the expected pulmonary vascular changes and right ventricular dilation seen in preterm-born children. Our multiscale modeling approach captures cardiopulmonary abnormalities across spatial scales and provides an innovative approach to explore the consequences of preterm birth beyond preclinical experimental data alone. This is a foundational step in understanding the impact of preterm birth on cardiopulmonary disease in childhood as well as adulthood.

AiXGa1−XN (0.7 < X < 1) Schottky Diodes Using Distributed Polarization Doped Layer With A Current Density Of 14 Ka/Cm2, Tariq Jamil, Abdullah Al Mamun Mazumder, Mafruda Rahman, Muhammad Ali, Grigory Simin, M. Asif Khan

Faculty Publications

High Al-content Al_xGa_1-xN (0.7 < x < 1) quasi-vertical Schottky barrier diodes (SBDs) with distributed polarization doping were grown on the bulk AlN substrate. They exhibit excellent rectification behavior with a large forward current density (~14 kA/cm² ) and a high breakdown field of ~8.3 MV/cm. The SBDs also exhibited low ideality factors of (n~1.2) with a high Schottky barrier height (Φ _b~ 1.7 eV). Thus, this study demonstrates the feasibility of the distributed polarization doping approach for high current–high voltage devices.

Who Is Presidential? Women’S Political Representation, Deflection, And The 2016 Election, Kaitlin M. Boyle, Chase B. Meyer

Faculty Publications

In 2016, Hillary Clinton was the first woman to gain the presidential nomination from a major political party in the United States, yet she was unsuccessful. The current study explores barriers to being elected as president for women generally and Hillary Clinton specifically. Using the propositions and tools of affect control theory, we demonstrate how women’s political representation shapes cultural sentiments about women and the president. In a nationwide sample of Americans surveyed shortly before the election, we find women’s representation on the state level influences voter preferences through these cultural sentiments: More women in politics makes a woman president …

Optimal Error Estimates Of The Diffuse Domain Method For Second Order Parabolic Equations, Wenrui Hao, Lili Ju, Yuejin Xu

Faculty Publications

In this paper, we study the convergence behavior of the diffuse domain method (DDM) for solving a class of second-order parabolic partial differential equations with Neumann boundary condition posed on general irregular domains. The DDM employs a phase-field function to extend the original parabolic problem to a similar but slightly modified problem defined over a larger rectangular domain that contains the target physical domain. Based on the weighted Sobolev spaces, we rigorously establish the convergence of the diffuse domain solution to the original solution as the interface thickness parameter goes to zero, together with the corresponding optimal error estimates under …

General Timing Games With Multiple Players, Alexander Matros, Vladimir Smirnov, Andrew Wait

Faculty Publications

We examine innovation in an n-player market-entry timing game with complete information and observable actions. In our novel multi-player setup, we allow for heterogeneous payoffs between players and leader payoff functions to be multi-peaked and non-monotonic, only requiring that followers’ payoffs are non-increasing with the time of the leader’s entry. We outline the conditions under which an n-player asymmetric game leads to standard second-mover advantage and preemption equilibria. In the context of a two-player game, we provide a comprehensive characterization of the pure-strategy equilibria for a general case. This includes the potential for the emergence of a new …

Wadsley-Roth (WR) niobates have emerged as high-rate anode materials that can combine rapid ionic diffusion with good electronic conductivity. WR compounds have been defect-enhanced by limited annealing, however, such materials often contain multiple types of defects. In particular, both Wadsley defects (variable block size) and transition metal disorder have the potential to modify transport rates, however the corresponding effects are not well understood mechanistically. Here, MoNb12O33 (MNO) was calcined at two different temperatures to compare a defect-rich condition (MNO-800) with a proximal order-rich condition (MNO-900) as assessed through XRD, XANES, EXAFS, and STEM characterizations.

Mechanical Performance Of Equilateral Triangular Lattices: The Role Of Nodal Fillets, Fakhreddin Emami, Andrew J. Gross

Faculty Publications

Triangular lattices are widely employed for their high strength to weight ratios, yet their mechanical performance is sensitive to geometric features, particularly the nodal geometry. This study investigates the influence of nodal geometry on the mechanical behavior of equilateral triangular lattices across a broad range of relative densities using high fidelity finite element simulations. We characterize the elastic properties, and strength limits as functions of fillet radius. Our results confirm the expected trend that, in stretching-dominated lattices with low relative density, the introduction of fillets reduces both stiffness and buckling resistance. In contrast, at higher relative densities, filleted nodes can …
