Sexual Knowledge in Late-Colonial Bombay: Contested Authority, Politicized Sciences
Date: 2022-01-01
Creator: Rahul Prabhu
Access: Open access
- Sexuality was at the fulcrum of various issues facing late-colonial India from social reform projects such as child marriage, women’s rights and birth control to concerns of socioeconomic, physical and sexual weakening. The question of sexual modernity became implicated in imaginations of the modern post-colonial nation, setting the stage for a period of energized, linguistically plural projects of sexual knowledge production. While science was used to authorize such projects in the West, where could authority be located in a context where science held plural meaning and authority itself was highly contested? This paper asks how scientific authority was understood, deployed and shaped by the eugenics project of Narayan Sitaram Phadke (1894-1978) and the sexology project of A.P. Pillay (1890-1956). This thesis argues that the mechanics of each figures’ utilization of science captures how the interaction between scientific authority and society was understood by Phadke and Pillay in different ways. While both figures subscribed to the idea that science was universally authoritative in the making of sexual modernity, Phadke’s and Pillay’s projects show the plurality in how science was understood by social reformers. Furthermore, the thesis presents the differences between Phadke’s and Pillay’s projects as a product of the larger movements – British-era birth control advocacy, Hindu nationalism, upper-caste marriage reform and global sexology – that Phadke and Pillay were distinctly invested in or separated from. Scientific authority and the mechanics of its use is proposed as a vivid lens into the complex dynamics of modernization in late-colonial India.

Narration, Nation et Nationalisme dans les récits d’enfance de Mouloud Feraoun et Mohammed Dib
Date: 2022-01-01
Creator: Reed Foehl
Access: Open access
- During the mid-20th century, a new form of Algerian literature emerged, thematically detached yet linguistically tied to France. Novelists aligned with this littérature algérienne de langue française used their narrative power to expose the atrocities of the colonial period, while emphasizing the rising nationalist spirit throughout the country. A peculiar aspect of this national literature is the presence of a child protagonist. Many of Algeria’s most prominent authors centered their first novels on a young boy. This leads to my central question: does the récit d’enfance (childhood narrative) possess certain qualities that lend it useful for representing ubiquitous suffering, as well as an imminent national awakening. My research focuses on two Algerian novelists, Mouloud Feraoun and Mohammed Dib, who employ the récit d’enfance for different aims. In this paper, I first define the récit d’enfance and show how Feraoun and Dib implement this literary style. Secondly, I argue that Mohammed Dib’s trilogy is distinctly political. Employing the critical theories of Frantz Fanon and Benedict Anderson, I contend that Dib’s trilogy, published between 1952-1957, is a littérature de combat (combat literature). Although Feraoun’s publication of Le Fils du Pauvre in 1950 inaugurated Franco-Algerian literature, his work is more reflective than political. Comparing Feraoun and Dib’s early work, allows me to expose the disparate narratives arising in the decade prior to Algerian independence. Their portrayal of colonial oppression, as well as the courage and ambition of an exploited people, remains useful when studying models of colonial and post-colonial nationalism and nation-state.

The Role of ELMO5 in Arabidopsis thaliana Cell Adhesion
Date: 2022-01-01
Creator: Isabel Kristina Ball
Access: Open access
- Plant cell growth and development relies on proper cellular adhesion. As the extracellular matrix serves as the area of connection between two cells, its synthesis and maintenance are essential for cellular adhesion. The middle lamella region, the layer of the extracellular matrix between two adjacent cell walls, is diffuse with the polysaccharide pectin due to its delivery by Golgi vesicles early during cell division. A Ruthenium Red screen for cellular adhesion mutants identified the family of 5 ELMO proteins that are critical for proper cellular adhesion. To further our understanding of plant cellular adhesion and pathways of pectin synthesis and modification, this work investigates ELMO5. Plants homozygous for a T-DNA insertion in ELMO5 and a new deletion mutant allele generated using CRSPR do not have a cellular adhesion phenotype, suggesting it is either not critical for cellular adhesion or is redundant with another gene. Redundancy within the ELMO family is identified through the analysis of double mutants of elmo5 and each of the other four elmo genes. Both elmo1-/- elmo5-/-and elmo4-/- elmo5-/-mutants have a visibly worse cellular adhesion defect phenotype, suggesting partial redundancy through the ELMO family. The mutants are also rescued by growth on agar, pointing to the importance of turgor pressure and osmotic potential in modulating cellular adhesion. Both ELMO4 and ELMO5 were found to localize to the Golgi using a GFP fusion, consistent with a role for ELMOs as scaffold for pectin biosynthesis.

Modeling the Development & Expression of Political Opinion: A Zallerian Approach
Date: 2024-01-01
Creator: Avery C Ellis
Access: Open access
- Research focused on John Zaller's famous RAS model of political opinion formation and change from "The Nature and Origins of Mass Opinion" (1992). Analyzed the mathematical and psychological underpinnings of the model, the first paper to do so in over fifteen years and the first to do so through an analysis of motivated reasoning and Bayesian reasoning. Synthesized existing critiques of Zaller's model and other literature to suggest ways to build on Zaller, utilizing fundamental reunderstandings of opinions and messages from political and mathematical perspectives. Found verification for Zaller's model, confirming its value, but also found support for the proposed RAIS model, which suggests foundational changes in the way citizens interact with information in the current political environment. Confirmed the utility of a Zallerian framework for analyzing shifts in mass opinion over time and suggested ways to improve the creation of surveys and polls for understanding elections and reported opinions on issues.

The role of modulation on the pyloric neurons and the neuromuscular junction in a pattern generator-effector system
Date: 2023-01-01
Creator: Jackie Seddon
Access: Open access
- Neuromodulation, the process of altering the electrical outputs of a neuron or neural circuit, allows an organism to control its physiological processes to meet the needs of both its internal and external environments. Previous work shows that the pyloric pattern of the kelp crab (Pugettia producta) stomatogastric nervous system (STNS) neurons responded to fewer neuromodulators than the Jonah crab (Cancer borealis). Since the kelp crab diet primarily eats kelp, it is possible that the movements of the foregut that control digestion may require less flexibility in functional output compared to an opportunistic feeder. To determine whether a reduced flexibility is correlated with diet, this study compared the modulatory responses in Pugettia to two other species of majoid crabs: Chionoecetes opilio and Libinia emarginata, which are both opportunistic feeders. Pooled data for this study found that Libinia and Chionoecetes responded to all twelve modulators tested. When considering the effect of modulators on stomatogastric ganglion (STG) motor outputs, we must consider whether these modulators also alter the excitatory junction potentials (EJPs) at the neuromuscular junction (NMJ), and whether there are differences in responses across species. To test this, the dorsal gastric nerve (dgn) was stimulated while recording intracellularly from the muscle fibers of the associated gm4 muscles. The NMJ of the gm4 in Cancer borealis did not appear to be broadly modulated, as only RPCH and CabTRP showed increases in amplitude, and RPCH decreased facilitation at 5 Hz.

New Institutional Economics: Political Institutions and Divergent Development in Costa Rica and Honduras
Date: 2022-01-01
Creator: Maynor Alberto Loaisiga Bojorge
Access: Open access
- For most of their histories, Costa Rica and Honduras were primarily agricultural societies with little economic diversification. However, around 1990, after the implementation of Washington Consensus reforms, the economies of both nations began to diverge. Costa Rica’s economy rapidly expanded for the following 30 years, while Honduras remained stagnant. Through a New Institutional Economics approach, I argue that institutional differences between Costa Rica and Honduras are responsible for the impressive economic growth Costa Rica has been able to achieve in the past few decades. Specifically, early political developments in Costa Rica have deeply imbedded relatively egalitarian values into the population, helping shape formal and informal inclusive political institutions. Meanwhile, Honduras experienced the development of extractive political institutions, as political and economic power was heavily concentrated in the hands of a select few. These political institutions were crucial during the implementation stages of Washington Consensus reforms, as strong and inclusive political institutions attracted Foreign Direct Investment that helped propel the Costa Rican economy and materialize its position as an outlier in the region. In contrast, lack of institutional guarantees discouraged foreign investors from investing money into the Honduran economy. Through a deep dive into the political histories of both nations, from European discovery to modernity, I conclude that the political institutions of these Central American nations have determined their economic growth paths.

Empire of Horror: Race, Animality, and Monstrosity in the Victorian Gothic
Date: 2022-01-01
Creator: Grace Monaghan
Access: Open access
- This project examines Victorian England through the analysis of three Victorian gothic novels: Bram Stoker’s Dracula (1897) and The Jewel of Seven Stars (1903/1912), and Richard Marsh’s The Beetle (1897). The end of the nineteenth century and the final years of the Victorian era brought with them fears and uncertainties about England’s role in the world and its future, fears that the Victorian gothic sought to grapple with, but inevitably failed to contain. In examining this genre, I draw on “Undisciplining Victorian Studies” (Chatterjee et al, 2020), which calls for the field of Victorian studies to center racial theory. As such, I foreground race and whiteness in these novels, in conjunction with animality, empire, and sexuality, all of which were crucial tools in the imperial gothic’s project of constructing the monstrous Other. The British empire relied on the establishment of a physical and moral boundary between itself and the colonized Other, in order to justify its imperialism and maintain its own perceived superiority. Yet, ultimately, this project demonstrates that the boundaries between the self and the Other, between morality and monstrosity, and between mainland England and its empire, were dangerously porous.

Diatom blooms in Harpswell Sound: seasonality, succession, and origin
Date: 2023-01-01
Creator: Charlie Francis O'Brien
Access: Open access
- Harpswell Sound (HS) is an inlet in northeastern Casco Bay that exerts control on Gulf of Maine ecosystem health, yet its complex phytoplankton community dynamics have not been characterized with sufficiently detailed analyses. In this research, high-resolution automated microscopy and current velocity observations were used to test the seasonality, ecological succession, bloom origin location, and potential toxicity of populations in HS between 2020 and 2022. Winter months could exhibit slow accumulation of diatom biovolume. Cold, salty surface water has net outflow in winter as nutrients from depth are replenished during net upwelling conditions, and populations could be exported from the inlet at the surface. Extreme current velocity variability in spring due to the Kennebec River plume in HS destabilizes spatially uniform populations. Warm, low-salinity surface water with net inflow in summer (net downwelling which retains populations at the head of the sound) corresponds with temporally separate dinoflagellate and diatom blooms. Large, multi-peaked spring and fall diatom blooms are recurrent, contrasting small, short-lived blooms in summer. A successional pattern from diatoms to dinoflagellates is confirmed for summer but refuted for other seasons. The hypothesis that diatom succession during all blooms in HS is characterized by large centric cells preceding small cells or pennate cells was explored but no clear pattern in decreasing cell size was observed. Observed tidal effects on biovolume concentration could mask that blooms develop at coherent times but spatially separated. A diverse community of toxic phytoplankton, including dinoflagellates and Pseudonitzschia, are observed throughout the year.
Eroding the Bedrock: The Future of Public Administration Without Chevron Deference
Date: 2024-01-01
Creator: Rose Keller
Access: Open access
- When Congress passes a bill, it produces words on a page. Who decides what those words mean? Historically, the onus of a statute’s interpretation has rested with the federal agencies charged with its implementation. The Chevron doctrine, a two-step standard that affords federal agencies significant latitude in interpreting their own enabling legislation, has been the applicable deference regime in statutory interpretation cases since 1984. Contrary to this tradition, recent Supreme Court jurisprudence has reasserted the primacy of the judiciary in statutory interpretation cases, often ignoring Chevron entirely. In 2023, the Court granted certiorari to Loper Bright Enterprises v. Raimondo, a case that explicitly asked the Court to consider overruling Chevron vs. NRDC, a foundational case in the field of administrative law. This thesis explores the implications of eroding deference to federal agencies through a case study of the Food and Drug Administration and two of its responsibilities. Ultimately, there are potentially negative consequences to limiting agency jurisdiction via eviscerating judicial deference that counsel a more discerning approach.

Blockholders and Their Effect on Project Value: An Empirical Approach of Understanding Ownership Concentration and Firm Value Using an Event Study Framework
Date: 2017-05-01
Creator: Xuanming Guo
Access: Open access
- This study uses an event study framework to find the relationship between ownership concentration and project value. I find that project value first increases with ownership concentration when block size, the percentage ownership of the largest blockholder, is smaller than 10%, then declines with ownership concentration when block size gets larger, and finally rises again when block size exceeds 30%. However, my research only suggests an ambiguous relationship between ownership concentration and firm value. Additionally, ownership concentration seems to affect both the timing of market responses and the market’s interpretation of large investment projects.

Activation of Hydrogen by Sterically Modulated Coinage Metal Catalysts via Mutual Quenching of Hard/Soft Acid/Base Mismatches
Date: 2024-01-01
Creator: Zach Leibowitz
Access: Open access
- To mitigate the devastating environmental impacts of climate change in the coming decades, it is imperative that we replace the use of fossil fuels with renewable energy sources such as wind, solar, and hydroelectric. As these renewable energy sources are inherently intermittent, there exists a need for sustainable mechanisms to store renewable energy for later use. While the direct use of dihydrogen (H2) as a combustible fuel would allow for energy storage without the harmful release of carbon dioxide (CO2) upon combustion, the practicality of H2 as a synthetic fuel is limited by its low volumetric energy density. Combining sustainable H2 production (e.g. electrolysis using energy from renewable sources) with subsequent carbon fixation (e.g. the hydrogenation of CO2) represents a promising pathway to the sustainable production of high-density synthetic fuels. We hypothesize that such a process could be catalyzed by an IPr**-supported catalyst containing a hard/soft acid/base (HSAB) mismatch, with a polarizable coinage metal acting as a soft acid. As such, the aim of our project is the construction of a catalogue of IPr**-supported copper, silver, and gold catalysts that we anticipate will facilitate the heterolysis of dihydrogen and subsequent hydrogenation of CO2. In the present paper, we report the synthesis and characterization of an IPr**-silver complex which will serve as a precursor to many of our proposed HSAB mismatch catalysts and discuss next steps as we construct our catalogue of catalysts.
