Teaching Computers to Teach Themselves: Synthesizing Training Data based on Human-Perceived Elements
Date: 2019-05-01
Creator: James Little
Access: Open access
- Isolation-Based Scene Generation (IBSG) is a process for creating synthetic datasets made to train machine learning detectors and classifiers. In this project, we formalize the IBSG process and describe the scenarios—object detection and object classification given audio or image input—in which it can be useful. We then look at the Stanford Street View House Number (SVHN) dataset and build several different IBSG training datasets based on existing SVHN data. We try to improve the compositing algorithm used to build the IBSG dataset so that models trained with synthetic data perform as well as models trained with the original SVHN training dataset. We find that the SVHN datasets that perform best are composited from isolations extracted from existing training data, leading us to suggest that IBSG be used in situations where a researcher wants to train a model with only a small amount of real, unlabeled training data.

Performing Sor Juana: Reimagining a Mexican Literary Figure in the 21st Century
Date: 2020-01-01
Creator: Uriel López-Serrano
Access: Open access
- Sor Juana Inés de la Cruz (c. 1648-1695) was a Mexican nun, poet, playwright, and scholar from the colonial era. She has become an icon for various global, social, and political movements. This project looks at four dramatic works created by Sorjuanistas who reimagine Sor Juana’s story for contemporary audiences living in the United States. The works included in this essay are Estela Portillo-Trambley’s Sor Juana (1986), Karen Zacarías’s The Sins of Sor Juana (2001), and Alicia Gaspar de Alba’s “Interview with Sor Juana Inés de la Cruz” (1998/2014) and her newest work, Juana: An Opera in Two Acts (2019), libretto by Carla Lucero. In addition to reimagining Sor Juana’s story, these dramatic works expose the sexism, racism, and xenophobia perpetuated by U.S institutions of power that discriminate against Latin@ and Chican@ individuals. By shedding light on the social injustices that existed during the colonial era, an embodied Sor Juana teaches audiences how to resist and mobilize against such oppressive powers. Sor Juana’s narrative on stage is necessary because she is a role model for Latin@s/Chican@s. Sorjuanistas remind us that the body can be used to retell the narratives of the silenced individuals who are victims of oppression. By developing heritage performances, Sorjuanistas challenge histories that silence and overlook social injustices. Witnessing Sor Juana on stage triggers emotional responses to the past which allow historical actors to obtain intellectual, emotional, and political agency in an effort to affirm and remember particular contemporary and future commitments to fighting social injustices.
Classifying Flow-kick Equilibria: Reactivity and Transient Behavior in the Variational Equation
Date: 2020-01-01
Creator: Alanna Haslam
Access: Open access
- In light of concerns about climate change, there is interest in how sustainable management can maintain the resilience of ecosystems. We use flow-kick dynamical systems to model ecosystems subject to a constant kick occurring every τ time units. We classify the stability of flow-kick equilibria to determine which management strategies result in desirable long-term characteristics. To classify the stability of a flow-kick equilibrium, we classify the linearization of the time-τ map given by the time-τ map of the variational equation about the equilibrium trajectory. Since the variational equation is a non-autonomous linear differential equation, we conjecture that the asymptotic stability classification of each instantaneous local linearization along the equilibrium trajectory indicates the stability of the variational time-τ map. In Chapter 3, we prove this conjecture holds when all of the asymptotic and transient behavior of the instantaneous local linearizations is the same. To explore whether the conjecture holds in general, we ask: To what degree can transient behavior differ from asymptotic behavior? Under what conditions can this transient behavior accumulate asymptotically? In Chapter 4, we develop the radial and tangential velocity framework to characterize transient behavior in autonomous linear systems. In Chapter 5, we use this framework to construct an example of a non-autonomous linear system whose time-τ map has asymptotic behavior that differs from the asymptotic behavior of each instantaneous linear system that composes it. Future work seeks to determine whether this constructed example can arise as a variational equation, and thus provide a counterexample for our conjecture.
Guarding Whiteness: Disability, Eugenics, and Rhetorical Agency in Southern Renaissance Fiction
Date: 2023-01-01
Creator: Philip Carl Bonanno
Access: Open access
- This project explores fiction from white authors in the Southern Renaissance, specifically William Faulkner, Flannery O’Connor, and Carson McCullers. By examining their work alongside some of the performers that appeared historically in freak shows of the South, chapter one investigates how physically enfreaked individuals (usually phenotypically white) have access to power and the powers of whiteness. Chapter 2 interrogates how the South pathologizes promiscuity as mental illness with words such as moronic or feeble-mindedness, and the ramifications it has for the stratification on class divides among Southern elites and “White Trash.” The chapter seeks to answer the question of why, for a short period in the 1940s, white women were more likely to be punished with forced sterilization than Black women. Chapter 3 uncovers the rhetorical agency used by Benjy in Faulkner’s The Sound and the Fury, looking at how he resists the powers of whiteness through crip time and his trauma responses to his family that seeks to reinsert the Antebellum South. Using an intersectional approach of critical whiteness studies, disability studies, crip theory, and queer theory, relies on a variety of scholars including, but not limited to; David Mitchell and Sharon Snyder, Rosemarie Garland-Thompson, Richard Dyer, Matt Wray, Jasbir Puar, Ellen Samuels, and Allison Kafer. The primary works examined include promotional materials of historical freaks, McCullers’ The Ballad of a Sad Café, William Faulkner’s The Hamlet and The Sound and the Fury, and Flannery O’Connor short stories “Good Country People” and “A Temple of the Holy Ghost.”
Church Space as Queer Place? LGBTQ+ Placemaking, Assimilation, and Subversion within Progressive Faith-Based Spaces in Maine
Date: 2023-01-01
Creator: Salina Chin
Access: Open access
- In popular discourse, understandings of queerness and religiosity as antithetical proliferate. However, the political involvement of Portland, Maine’s First Parish Unitarian-Universalist Church in Maine’s queer political movement points to a more complex relationship between the LGBTQ+ community and progressive religious institutions. Through participant observation, archival research, and semi-structured interviews with nine LGBTQ+ community members and informants, I reveal the crucial role of Portland’s First Parish Unitarian-Universalist Church in Maine’s queer political movement from the late 1980s into the present day. On the one hand, progressive faith-based spaces across Maine provide safe spaces for queer political organizing. On the other hand, “ephemeral placemaking” in progressive faith-based spaces represents an assimilationist political strategy that stresses LGBTQ+ respectability. Thus, I argue that queer placemaking in progressive faith-based spaces reflects both subversive and assimilationist politics. LGBTQ+ activists utilize ephemeral placemaking strategies within progressive faith-based spaces to challenge political opposition from the religious Right while also reinforcing what Mikulak (2019) terms “godly homonormativity”: the normalization of LGBTQ+ identity and the upholding of heteronormativity by emphasizing respectability and monogamy. My analysis of queer political organizing within progressive faith-based spaces “queers” religion and LGBTQ+ politics, disrupting dominant narratives of religion as homophobic and LGBTQ+ politics as radical.
Power Play: The President's Role in Shaping Renewable Energy Regulation and Policy
Date: 2023-01-01
Creator: Luke Bartol
Access: Open access
- With the impacts of climate change becoming more and more apparent every day, finding means of effective action to mitigate its effects become increasingly critical. While localized work can play an important role, federal action is necessary to have the most widespread and effective impact, especially on interconnected issues such as clean energy. Congressional action is the avenue of change at this level, however in an increasingly partisan and divided environment, progress on this front is far short of what is needed. Looking to the president is logical here, both as a single actor more insulated from partisan fights, but also as head of the branch in charge of implementing the nation’s laws. This paper looks to explore what means of influence the president has on the action taken by federal agencies and how such methods can be made more effective. Through a principal-agent framework, the role of regulatory and appointment powers are examined with a variety of historical and contemporary case studies. While only a subset of the powers afforded to a president, the areas explored offer wide latitude for action, in areas that are particularly important for energy development. The paper concludes with some reflections for the future, suggesting how these considerations can be practically applied.
“Something most girls don’t do” An Ethnographic Study of Women in Extreme Sports
Date: 2022-01-01
Creator: Jacqueline Boben
Access: Open access
- Extreme sports, like skateboarding, whitewater kayaking, and skiing, have historically been male-dominated. As women’s participation in these sports grows, my research asks: how do women navigate sports spaces and cultures that have for so long been defined by men? To answer this question, I draw on ethnographic research on communities of skateboarders, whitewater kayakers and skiers conducted during the summer of 2021 in Bozeman, Montana. I found that the specific landscapes where these extreme sports take place are often conceptualized by participants as more masculine spaces. Within these spaces and communities, women participants often leverage gender performances associated with masculinity to gain entry into these male-dominated communities. Performing in more masculine ways mitigates feelings of hypervisibility, while also helping to build connections to established members of the community. More than simply fitting in, women find that these gendered performances also help them to build competence in the sport. At the same time, women are transforming skateboarding, whitewater kayaking, and skiing through their participation by creating opportunities for more dynamic and fluid gender performances.
Modeling UV Light Through N95 Filters

Creator: Lorenzo Hess
Access: Open access
- Reuse of N95 FFRs helps mitigate the effects of shortages. UV-C exposure is an ideal method for the decontamination necessary for FFR reuse. Recent research quantifies the transmittance of UV-C through the 3M1870+ and 3M9210+ FFRs [1]. Other research measures the reduction in viral load in relation to UV-C exposure time [11]. We design and program a ray tracing simulator in MATLAB to characterize the distribution of scattered photons in N95 FFRs. We implement an object-oriented FFR with configurable physical characteristics. We use the simulator to record the number of photons available for decontamination in each sub-layer of the filtering layers of the 3M1870+ and 3M9210+ for a given number of photons incident to the layers. We make assumptions about the photon absorption and viral deactivation in each sub-layer to derive a relation between the number of incident photons and the number of viruses remaining. The transmittance computed by our simulator matches the experimentally measured transmittance. The diameter of the simulated scattered beam also matches the experimentally measured scattered beam diameters. Our data, combined with our assumptions about absorption and deactivation, however, fail to account for the dropoff in viral load observed at about 25 seconds of exposure time in the 3M1870+.
