The Ethiopian Student Movement and the Dilemma of Eritrean Sovereignty
Date: 2024-01-01
Creator: Liat G. Tesfazgi
Access: Open access
- From the perspective of Ethiopian royalists, Pan-Africanists, Marxist internationalists, supports of union, and the broader international community, Eritrean nationalism revealed distressing fissures in many different arguments for preserving Ethiopian territorial unity– arguments not necessarily or explicitly problematic, but nevertheless in opposition to Eritrean demands for the right to national self-determination. For the Ethiopian Student Movement (ESM) specifically, Eritrean sovereignty demanded a reconfiguration of Pan-African unity that conflicted with Ethiopian exceptionalist historiography. Through an analysis of student politics at Haile Selassie University, from 1960-1974, this thesis seeks to complicate existing historiography on the ESM by examining the periodically divergent experiences of Eritrean student activists.
Neural compensation in response to salinity perturbation in the cardiac ganglion of the American lobster, Homarus americanus
Date: 2024-01-01
Creator: Josephine P. Tidmore
Access: Open access
- Central pattern generator (CPG) networks produce the rhythmic motor patterns that underlie critical behaviors such as breathing, walking, and heartbeat. The fidelity of these neural circuits in response to fluctuations in environmental conditions is essential for organismal survival. The specific ion channel profile of a neuron dictates its electrophysiological phenotype and is under homeostatic control, as channel proteins are constantly turning over in the membrane in response to internal and external stimuli. Neuronal function depends on ion channels and biophysical processes that are sensitive to external variables such as temperature, pH, and salinity. Nonetheless, the nervous system of the American lobster (Homarus americanus) is robust to global perturbations in these variables. The cardiac ganglion (CG), the CPG that controls the rhythmic activation of the heart in the lobster, has been shown to maintain function across a relatively wide, ecologically-relevant range of saline concentrations in the short-term. This study investigates whether individual neurons of the CG sense and compensate for long-term changes in extracellular ion concentration by controlling their ion channel mRNA abundances. To do this, I bathed the isolated CG in either 0.75x, 1.5x, or 1x (physiological) saline concentrations for 24 h. I then dissected out individual CG motor neurons, the pacemaker neurons, and sections of axonal projections and used single-cell RT-qPCR to measure relative mRNA abundances of several species of ion channels in these cells. I found that the CG maintained stable output with 24 h exposure to altered saline concentrations (0.75x and 1.5x), and that this stability may indeed be enabled by changes in mRNA abundances and correlated channel relationships.

Digital Market Concentration: An Institutional and Social Cost Analysis
Date: 2022-01-01
Creator: Jack Shane
Access: Open access
- In this thesis, I develop an analysis of the industry concentration seen in digital markets today. I begin with a description and argument for the use of institutional economics. This framework allows for the integration of an interdisciplinary approach to economics. My analysis details the socioeconomic and political impacts, as well as the underlying market dynamics that have pushed digital markets towards concentration. I offer novel explanations for the lack of firm behavior that should theoretically increase profit, the existence of barriers to competition, and consumer behavior that focus on the role of social institutions. I also detail many of the social costs of these concentrated markets, such as their impact on democracy, power to influence social institutions, and the impact they have on concentration in other markets. This is done to show that the fears surrounding monopolies do not end with prices. Even in digital markets, where many times prices are very low, if not zero, there are reasons that monopoly is economically inefficient and socially sub-optimal. However, due to the path-dependent nature of the extreme benefits associated with digital markets, policymakers cannot reasonably propose breaking up these companies. Instead, they must use the power of the government to counteract the conglomerations of social power seen in these private companies in search of an optimal outcome.
The Independent State Legislature Theory and Partisan Gerrymandering: How Moore v. Harper May Reshape Congressional Elections
Date: 2023-01-01
Creator: Luke Porter
Access: Open access
- In 2019, the U.S. Supreme Court ruled in Rucho v. Common Cause that partisan gerrymandering is not a justiciable question for federal courts. Four years later, the Court is reviewing a new case, Moore v. Harper. In Moore, the question presented is whether state courts can review partisan gerrymandering. The central question in Moore is the validity of the Independent State Legislature Theory. Proponents of the ISLT believe that state legislatures derive their authority to draw Congressional districts from the Federal Constitution and are therefore not subject to state-level checks and balances such as gubernatorial vetoes and state courts when redistricting. Critics argue that neither precedent nor the intent of the Framers grants state legislatures exclusive authority over redistricting. This paper analyzes the history of the Independent State Legislature Theory and outlines potential standards that the Court may adopt based off past-precedent. It then applies these standards to the redistricting process, arguing that nearly any form of the Independent State Legislature Theory would harm American democracy by making it easier for state legislatures to draw Congressional districts for partisan advantage. This paper concludes with strategies for mitigating the harm that would be caused if the Court legitimizes the Independent State Legislature Theory.
James Joyce’s Prose Pedagogy: Language in Freirean Dialogue
Date: 2023-01-01
Creator: Jack McDermott Wellschlager
Access: Open access
- My project concerns the pedagogical nature of James Joyce’s Ulysses. Across the various styles and forms of Ulysses’ chapters, or “episodes,” I theorize the pedagogy of James Joyce’s prose by tracking the ways that the text demands readers participate in a Freirean dialogue. I will also discuss how Ulysses understands language as a practice of resistance: the novel’s characters have personal linguistic practices that help them open up the worlds that occupy them. I will appreciate the control these characters take of their world as I argue, through Paulo Freire’s work, that no true change occurs without the presence of a cooperative worldbuilding effort.
Effects of Picrotoxin Application on the Cardiac Ganglion of the American Lobster, Homarus americanus
Date: 2023-01-01
Creator: John T Woolley
Access: Open access
- Picrotoxin (PTX) has been employed extensively as a tool within the crustacean stomatogastric nervous system (STNS) for its efficacy in blocking K+ and Cl+ currents gated by both GABA and glutamate. Through blocking some currents in the STNS, PTX allows for examination of other components without their presence. However, effects of PTX are relatively unknown within the lobster’s cardiac ganglion (CG). As an incredibly small nervous system of only nine neurons, the lobster CG presents an excellent model system for studying neural circuits. Given that the chemical synapses in the CG are mediated by glutamate, the present study aimed to investigate the action of PTX in the lobster CG with the intent of better understanding its pharmacological impacts as a potential tool for studying the system. Therefore, this study aimed to establish the effects of PTX on CG responses to the application of exogenous GABA or glutamate. When data from both modulators were pooled, PTX applied at a concentration of 10-5M had significant effects on burst duration but not duty cycle or burst frequency of the CG. PTX did suppress GABA (5x10-5M) mediated inhibition of burst duration and duty cycle. PTX did not have any significant effects on burst duration, duty cycle, or frequency compared to exogenous glutamate application. These results indicate that glutamatergic inhibitory synapses are not present in the CG and PTX partially suppresses only GABAergic responses in this system.
Bodies, Memories, Ghosts, and Objects or Telling a Memory

Creator: Natsumi Lynne Meyer
Access: Open access
- I think it started in December 2017, when my Mama sent me to Japan to take care of my grandparents, Baba and Jiji, alone. I had been to Japan almost every year since I was eleven years old, and several times before that too, but this was my first time without Mama. When Mama was there, Japan was filtered through her. I could poke bits of myself through her editing and approval. I could read street signs because of the way she read them, and I could understand my grandparents’ sighs from the timbre of her translation. That December, though, I had to see and hear alone. The tiny shakes in Baba’s legs and the indentation in Jiji’s forehead from when he fell down the stairs crystallized in my memory, and I had to write about it. This project includes a series of creative nonfiction and fiction pieces centered around telling my family stories. Writing from interviews, observations, and generational memories, I weave together these story fragments to discuss Asian American identity and immigration, WWII trauma, aging, and inheritance.
