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.
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.
Characterization of expression of Sema1a variants in high-plasticity areas of the Gryllus bimaculatus nervous system

- The well-conserved semaphorin family of guidance molecules is known to play multiple complex roles in directing the growth and orientation of dendrites and axons within the developing invertebrate central and peripheral nervous system. Additionally, the expression of select semaphorins is maintained within some highly plastic areas of the adult central nervous system, such as the mushroom bodies, where they are associated with guidance of newly-born neurons as well as with synapse formation and modification. Within the cricket species Gryllus bimaculatus, deafferentation of the prothoracic ganglia and subsequent dendritic rearrangement of the auditory interneurons is associated with fluctuations in the expression of transmembrane Sema1a and diffusible Sema2a. Here, we characterize the expression of two different variants of Gryllus Sema1a, termed Horch Sema1a and Extavour Sema1a, in tissues associated with both developmental neuronal guidance and adult structural plasticity: the embryonic limb buds, the mushroom bodies of the brain, and the non-deafferented adult prothoracic ganglion. Although we were unable to visualize the expression of Extavour Sema1a in any tissue, we demonstrate via phylogenetic analysis that both Sema1a variants have homologs in species across the Insecta class, suggesting that Extavour SEMA1a is a conserved protein sequence. We observe no expression of Horch Sema1a in the embryonic limb bud, and suspect that Extavour Sema1a, which has a high pairwise identity with Schistocerca Sema1a, could be facilitating guidance of the tibial pioneer neuron growth in the limb bud, along with Sema2a. In the adult brain, we observe a colocalization of Horch Sema1a and Sema2a in the mushroom bodies and in a vertical stripe across the calyx, which may be indicative of interactions between Horch SEMA1a and SEMA2a in maintaining synaptic plasticity and guiding newly-born Kenyon cells. We also report a colocalization of Horch Sema1a and Sema2a in the anterior and posterior of the prothoracic ganglia on the ventral side, in the region of auditory interneuron cell bodies, suggesting the possibility that auditory interneurons may express both Horch Sema1a and Sema2a, which could interact with each other or with Plexin receptors to regulate dendrite morphology at the midline.
The Scars of War: The Demonic Mother as a Conduit for Expressing Victimization, Collective Guilt, and Forgiveness in Postwar Japanese Film, 1949-1964

Creator: Sophia Walker
Access: Open access
- Contemporary American viewers are familiar with the vengeful and terrifying ghost women of recent J-Horror films such as Ringu (Nakata Hideo, 1998) and Ju-On (Shimizu Takashi, 2002). Yet in Japanese theater and literature, the threatening ghost woman has a long history, beginning with the neglected Lady Rokujo in Lady Murasaki’s 11th century novel The Tale of Genji, who possesses and kills her rivals. Throughout history, the Japanese ghost mother is hideous and pitiful, worthy of fear as well as sympathy, traits that authors and filmmakers across the centuries have exploited. This project puts together four films that have never before been discussed together -- Kinoshita Keisuke's Shinsaku Yotsuya Kaidan (1949), Nakagawa Nobuo's Tokaido Yotsuya Kaidan (1959) Mizoguchi Kenji's Ugetsu (1953), and Shindo Kaneto's Onibaba (1964) -- and discusses them as four different iterations of the demonic mother motif, presented as a projection of the Japanese collective’s postwar uncertainty over both the memory of suffering during World War II and the question of personal culpability.
"Cooperate with Others for Common Ends?": Students as Gatekeepers of Culture and Tradition on College Campuses
Date: 2017-05-01
Creator: Pamela Zabala
Access: Open access
- As colleges and universities have increased efforts to make their campuses more racially and ethnically inclusive, students of color still perceive their campuses as hostile spaces to racial and ethnic minorities. On the other hand, white students often feel as though their institutions do too much, leaving administrators to balance the interests of both groups. This thesis draws on archival, ethnographic, and interview data collected at Bowdoin College to examine the relationship between students and between students and administrators given the role of students as major agents of change on college campuses. I have found that when students feel threatened by institutional change, they go into crisis and create spaces of resistance on campus. Institutions are incapable or unwilling to find solutions that meet the needs of the various constituencies within the student body. Therefore, students and administration become locked in a power struggle that produces only surface-level institutional change rather than meaningful reform in the face of rising racial tensions.
Examining the role of GRP and LIK1 in Wall Associated Kinase (WAK) perception of pectin in the plant cell wall
Date: 2017-01-01
Creator: Jack Ryan Mitchell
Access: Open access
- Wall associated kinases (WAKs) are cell membrane bound receptor kinases that bind pectin and pectin fragments (OGs).The binding of WAKs to pectin sends a growth signal required for cell elongation and plant development. WAKs bind OGs with higher affinity than native pectin and instead activate a stress response. Glycine rich proteins (GRPs) are secreted cell wall proteins of unknown function. Seven GRPs with 65% sequence similarity are coded on a 90kb locus of Arabidopsis chromosome 2. GRP3 and WAK1 have been shown to bind in vitro, but single null mutations have no discernible phenotype, suggesting that the GRPs are redundant. Low recombination frequency has made multiple mutations difficult to achieve, but in this thesis, CRISPR/Cas9 technology was used to induce deletions of the GRP locus. The promoters pYAO and pICU2 drove Cas9 expression in transformed Arabidopsis plants. The presence of a deletion and Cas9 were detected by PCR. While somatic mutations were induced, there was no inheritance of the GRP deletion, indicating that pYAO and pICU2 do not drive Cas9 to induce deletions in progenitor cells. LIK1 is a CERK1 interacting kinase implicated in mediating response to various microbe associated molecular patterns (MAMP) such as chitin, flagellin, and peptidoglycans. LIK1 exhibits a drastic increase in phosphorylation in response to OG treatment, making it a candidate for a co-receptor to WAK. T-DNA insertions to the 5’UTR of LIK1 were used to examine the effect of a lik1 mutation on the OG induced stress response. lik1/lik1 mutant seedlings were grown in the presence and absence of OGs, and RNA was isolated. qPCR was used on cDNA to examine FADLOX expression, a reporter for the transcriptional response to OGs. The lik1/lik1 mutant caused a reduction in the OG induced transcriptional response. However, increased LIK1 expression was associated with the T-DNA insertion indicating that LIK1 inhibits the WAK stress response pathway. Understanding the roles of GRP and LIK1 in moderating WAK mediated pathogenic response in Arabidopsis will enable a better understanding of plant resistance to pathogen invasion in the greater plant kingdom.
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.
