From American Dream to American Reality: The Effect of Educational Expenditures on Intergenerational Mobility and the Great Gatsby Curve
Date: 2022-01-01
Creator: Isabel Krogh
Access: Open access
- Income inequality and intergenerational mobility are two common measures of economic fairness in society. While they measure distinct ideas, they are significantly related in an inverse way across countries as well as across regions in the United States. This relationship is illustrated on the Great Gatsby Curve. Unequal access to education is one factor that has been found to drive the negative relationship between these two measures and therefore create the negatively sloping Great Gatsby Curve. Therefore, creating more equal access to education, such as through government spending, could lessen the connection between these two factors. The primary purpose of this research is to explore the effect of public educational expenditure on intergenerational mobility as well as on the slope of the Great Gatsby Curve. At the primary/secondary education level, this study finds that places with higher public spending on education tend to have higher levels of intergenerational mobility. However, no significant relationship is found between spending on tertiary education and intergenerational mobility. In addition, while higher primary/secondary educational spending is associated with a flatter Great Gatsby Curve at the school district level, these results were not consistent at the commuting zone level, so no strong conclusions can be made about the effect of public educational expenditures as a mediating factor of the Great Gatsby Curve.

Bodies, Memories, Ghosts, and Objects or Telling a Memory
Date: 2023-01-01
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.
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.
Modeling and Testing Consumer Engagement in the U.S. Organic Food Market
Date: 2016-05-01
Creator: John L Anderson
Access: Open access
- This study specifies the types of consumers that participate in the U.S. organic market and investigates their revealed preferences. I propose three theoretical consumer types – indifferent consumers, informed organic food lovers, and uninformed organic food lovers – and conduct cross-sectional and time-trend analyses utilizing organic fruit purchase data compiled by The Neilsen Company. The cross-sectional analysis is estimated with a two-stage Heckman selection model, while the time-trend analysis uses simple descriptive statistics and a differenced OLS regression technique. Households are most likely to participate in the organic fruit market if they have a well-educated white or Asian head, are located in a metropolitan area on the West coast, have higher income, have young children, are married, and are making decisions in the spring, summer, or fall. However, households are estimated to purchase more organic fruit, conditional on participating, if they live in a rural area in regions other than the West coast. Having a higher income, being married, having a child less than six years old, being college-educated, and living in a metropolitan area on the West coast are all associated with more dedication to the organic fruit market over time. Households who increased their organic expenditures from 2011 to 2012 likely lived in metropolitan areas on the West coast. Average per-household contribution to the nationwide increase in organic fruit expenditures from 2011 to 2012 on the extensive and intensive margins is estimated to have been about $7 and $14, respectively. I posit relationships between empirical results and the theoretical consumer types.

Dietary diversity correlates with the neuromodulatory capacity of the stomatogastric nervous system in three species of majoid crabs
Date: 2023-01-01
Creator: Elise Martin
Access: Open access
- This project sought to answer the following question: what is the relationship between the extent of neuromodulation in a nervous system, and the behavioral demands on that system? A well-characterized CPG neuronal circuit in decapod crustaceans, the stomatogastric nervous system (STNS), was used as a model circuit to answer this question. The stomatogastric ganglion (STG) in the STNS is responsible for muscular contractions in the stomach that aid in digestion. It has been shown that the neural networks in the STG are subject to neuromodulation. One feature of neuromodulation is that it enables circuit flexibility, which confers upon a system the ability to produce variable outputs in response to specific physiological demands. It was hypothesized that opportunistic feeders require more extensively modulated digestive systems compared to exclusive feeders, because opportunistic feeders require a greater variety of digestive outputs to digest their varied diets. In this study, Chionoecetes opilio and Libinia emarginata, the opportunistic feeders, showed greater neuromodulatory capacity of the STNS than Pugettia producta, the exclusive feeder. The hypothesis that neuromodulatory capacity of the STNS correlates with dietary diversity was supported. The results detailed in this study lend credence to the idea that evolutionary basis for neuromodulatory capacity of a system is related to the behavioral demands on that system.
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.
